Description

  The present invention mainly relates to a garbage disposal system that decomposes food waste into carbon dioxide and water using microorganisms.

  In nature, garbage is weathered over time and is degraded by bacteria such as soil fungi. There is a garbage processing system that applies the natural waste decomposition method, and in particular can decompose food waste in a short time (see, for example, “Patent Document 1”).

  In addition, Guangai Sangyo Co., Ltd., based on the Bacillus genus that prevails in the natural world in soil, dead grass, and air, is a cellulose-degrading bacterium of facultative anaerobic bacteria (amphoteric) and aerobic bacteria Bacteria in which animal oil-degrading bacteria, vegetable oil-degrading bacteria, mineral oil-degrading bacteria, protein-degrading bacteria, lignin-degrading bacteria (woody fungi) and the like were symbiotic to the treated product were developed as KOAI bacteria (trademark pending) (for example, , See “Non-Patent Document 1”).

  By introducing this bacterium into a garbage disposal system, food waste containing polyethylene and polystyrene mainly from garbage is decomposed, and even if it is food waste in plastic bags, cases or packs, Over 24 hours, the volume reduction rate can be over 98%.

  In introducing such a garbage disposal system, first, the amount and components of food waste (generally called “garbage”) such as garbage, leftover food, packed cooked foods, and wrapped foods It is necessary to conduct surveys to determine the location of the garbage disposal system, the processing capacity, the composition of the bacteria used and the maintenance program.

  The maintenance program refers to a schedule related to the treatment and maintenance of the garbage treatment system, such as the composition of the bacteria to be used, the amount of bacteria to be used, the temperature setting in the stirring tank, the inspection, adjustment and repair of the garbage treatment system.

  As for the actual condition survey before the introduction of the system, an appropriate maintenance program could not be created unless the amount and components of garbage discharged by the planned users in the installation area were surveyed and estimated over a long period of about one year. The amount and composition of garbage is varied. For example, depending on the type of business such as restaurants, department stores, convenience stores, stations, etc., their sizes, and regions, the amount and composition of food waste will change even during the day, and the change will be severe depending on the day of the week, season, and weather conditions. Because. Therefore, there is a problem that creation of a maintenance schedule takes time, labor and cost.

JP-A-9-1112 Refer to the Nikkei, published January 9, 2004.

  The present invention provides a system for processing garbage by analyzing the weight of garbage brought in by a user for at least one week while processing the garbage.

  Each of the first aspects of the present invention includes a stirring mechanism for stirring garbage with a motor, a load sensor for detecting the load of the motor, and a deodorizer for deodorizing the smell emitted from the garbage. First and second garbage processing systems for processing garbage, a data input unit for inputting user identification information and garbage input date, and input only when the identification information matches pre-registered information Opening / closing unit that opens the mouth, weight sensor that detects the weight of the garbage thrown in from the inlet, a crusher that crushes the garbage thrown in from the inlet, and a deodorizer that deodorizes the smell emitted from the garbage A switching valve for sending the garbage crushed by the crusher to the first and second garbage disposal systems, the load data detected by the load sensor, and the weight sensor A garbage data file for storing the weight data respectively, and controlling the switching valve based on the load and weight data stored in the garbage data file, and the first and second garbage processing systems perform processing. Inspecting schedule of the agitating mechanism and the deodorizer based on the weight data accumulated for at least one week accumulated in the garbage data file, with the weight of the garbage and the load of the motor being substantially equalized And a processor for determining a schedule for adjustment and replenishment of the bacteria.

  The garbage processing system of the present invention creates and executes a maintenance program based on at least one week's worth of processing results, and accumulates and analyzes the processing data executed in this manner, so that the garbage processing is more realistic. Accurate maintenance inspection can be performed.

  Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing an embodiment of a garbage disposal system to which the present invention is applied. This garbage disposal system includes a controller 11, a garbage inlet 12, an agitation tank 13, a drive motor 14, an agitation mechanism 15, a deodorizer 16 and an exhaust device 17.

  In the garbage processing system, garbage is input from the garbage input port 12. The input garbage is sent to the stirring tank 13. The garbage is stirred by the stirring mechanism 15 in the stirring tank 13. Although not shown, the stirring mechanism 15 has a plurality of paddle-shaped arms in the direction of the axis of rotation, and a helical claw that crushes garbage with a small gap on the inner wall of the stirring tank 13 at the tip of these arms. Is attached. For this reason, when the stirring mechanism 15 is rotated by the drive motor 14, the garbage is efficiently crushed. If it is better to crush before stirring, a crusher may be provided.

  Garbage crushed by the stirring mechanism 15 is stirred together with bacteria in the stirring tank 13 as the stirring mechanism 15 rotates. The rotation of the stirring mechanism 15 is reversed, for example, every 30 minutes so that the garbage is uniformly processed, and the garbage is decomposed by bacteria over 24 hours.

  Bacteria are based on bacteria of the genus Bacillus that are ubiquitous in the natural world in soil, dead grass, and air. Cellulolytic bacteria, animal oil-degrading bacteria, vegetable oil-degrading bacteria, vegetable oils Any of the degradation bacteria, mineral oil-degrading bacteria, protein-degrading bacteria, lignin-degrading bacteria (woody fungi) and the like that are symbiotic to the treated product, or known ones that are used for garbage treatment may be used. In the case of the former bacterium, it is possible to treat it including packaging such as vinyl. In addition, the composition and amount of bacteria are adjusted according to the ratio of packaging of food waste and vinyl. Bacteria are put into the stirring tank 13 using a porous ceramic as a fungus bed. The fungus bed has a size of about 15 mm and preferably has a shape with an acute angle rather than a granular shape in order to promote finer crushing of garbage.

  Garbage is decomposed by the decomposition action of bacteria, and a part of the garbage adheres to the inner wall of the agitation tank 13, but is scraped off by a spiral claw, and in the discharge part of the agitation tank 13 as the agitation mechanism 15 rotates. Collected as a residue.

  The gas generated when the garbage is decomposed by the decomposition action of bacteria is heated to a high temperature of 300 ° C., and the platinum catalyst having a honeycomb structure provided in the deodorizer 16 oxidizes the gas. The deodorized gas is released to the atmosphere by the exhaust device 17.

  The residue can be used for secondary processed products such as concrete. The volume reduction rate of the garbage ranges from 97% to 98%, and the garbage with an input capacity of 100 liters (l) is reduced to a residue of 2 liters (l) to 3 liters (l). The volume reduction rate depends on the ratio of food waste and the vinyl that wraps it.

  FIG. 2 is a block diagram of the controller 11. The controller 11 includes a data input unit 21, a sensor unit 23, a slot opening / closing unit 24, a memory 25, a processor 22, a display unit 26, and a printer 27.

  The controller 11 identifies the user, analyzes the garbage that is brought in, processes the analysis data, and creates and executes a maintenance program. For the creation and execution, the processor 22 executes a program stored in the memory 25 to create various data and the data input unit 21, sensor unit 23, slot opening / closing unit 24, memory 25, display unit 26, and printer. This is done by controlling 27.

  The data input unit 21 reads user identification information input from a bar code, credit card, prepaid card or input keyboard held by the user. Since the user often wears gloves and brings the garbage into the garbage disposal system, it is preferable to attach a bar code to the bag containing the garbage in advance so that the user can be identified. Even in the case of applying biometric authentication, it is preferable to recognize by a part other than the hand in consideration of wearing gloves.

  The sensor unit 23 detects the weight of the garbage, the temperature and humidity in the stirring tank 13, or the load of the drive motor 14. Furthermore, in order to obtain analysis data with higher accuracy, it is desirable to provide a sensor capable of detecting the volume, components, pressure in the agitation tank 13, gas or gas component, odor or odor component.

  The inlet opening / closing unit 24 controls the opening / closing of the inlet 12. The insertion port opening / closing unit 24 is provided only when the identification information of the user read by the data input unit 21 is the registered user identification information and the identification information indicating that the user is a maintenance inspector. open. Furthermore, the slot opening / closing unit 24 closes the slot 12 when a predetermined time has elapsed. The charging port opening / closing unit 24 performs the input of garbage by registered users and the maintenance by a maintenance inspector.

  The memory 25 includes a garbage data file 25a, a user data file 25b, a maintenance data file 25c, a garbage analysis program file 25d, an input garbage pattern file 25e, a maintenance program file 25f, a charging program file 25g, and a related information file 25h. A control program file 25i is stored.

  The processor 22 controls each unit 21, 23, 24, 25, 26, 27 by executing processing according to the control program file 25i. The display unit 26 and the printer 27 execute data display and output of data processing of the processor 22.

  The garbage data output from the sensor 23 is accumulated in the garbage data file 25a. The user data file 25b stores data such as the user name, scale, type of business, and registration date. In the maintenance data file 25c, information is stored regarding which maintenance inspector has supplied the composition of bacteria, when the bacteria bed has been supplemented, and whether the mechanical parts have been maintained or adjusted. In the related information file 25h, region-specific reference data such as weather and population is stored in advance. The input garbage pattern file 25e stores change patterns analyzed by user name, scale, industry, date, weather, or region.

  An analysis program is stored in the garbage analysis program file 25d. The processor 22 executes processing according to the garbage analysis program file 25d, reads and analyzes the garbage data file 25a and the user data file 25b or the related information file 25h, and stores the names of the accumulated garbage users, Pattern and output changes according to scale, type of business, date and time, weather, or region.

  The maintenance program file 25f stores a maintenance program created in accordance with the input garbage pattern file 25e. In this maintenance program, according to the input garbage pattern file 25e, the replenishment time and composition and amount of bacteria, the replenishment time and amount of fungus bed, the temperature and humidity setting of the stirring tank 13, the stirring mechanism 15 and the deodorant The inspection time for maintenance and adjustment of the garbage disposal system components such as the machine 16 is described.

  The accounting program is stored in the accounting program file 25g. The processor 22 charges the user mainly by the weight of the input garbage by executing the charging program file 25g.

  Charging is performed by accumulating the usage fee values for each user and storing them in the user data file 25b. You may make it accumulate | store the value of a fixed usage charge, but it reads the input garbage pattern file 25e, analyzes the time slot | zone with little input amount of garbage, and uses the usage charge corresponding to the said time slot | zone. The values may be accumulated. For example, the amount of garbage input can be leveled in time zones by reducing the usage fee.

  The user identification information read by the data input unit 21 is collated by the processor 22 with the user data file 25b in the memory 25. When the processor 22 confirms that the user is a registered regular user by collation, the processor 22 outputs a control signal for opening the slot 12 to the slot opening / closing unit 24.

  When the input port 12 is opened and the garbage is input, the sensor unit 23 measures the weight and components of the input garbage. The sensor unit 23 outputs the obtained garbage data to the processor 22, and the processor 22 performs an accounting process for each user from the garbage data according to the accounting program file 25g.

  The accumulated value of the usage fee or the charged value is stored in the user data file 25 b, displayed on the monitor by the display unit 26, and printed by the printer 27. Therefore, the user can immediately check how much the garbage processing cost is incurred from the monitor display data of the display unit 26 and the invoice issued from the printer 27 when the garbage is thrown in.

  FIG. 3 is an example of garbage data indicating a change in the daily garbage amount per hour. FIG. 4 is an example of the daily garbage data for each week and by region. The amount of garbage varies greatly depending not only on the time of the day, but also on environmental conditions such as the user's industry, scale, region, weather conditions, and seasons. FIG. 5 is an input garbage pattern file 25e showing the type of garbage change pattern created by the accumulation of garbage data shown in FIG. 3 and FIG. 4, and the annual garbage input for each user. It shows the amount.

  The present inventor can periodically grasp the amount of garbage discarded by local users and the change of ingredients for each day of the week, at least in units of one week. The amount of waste input also changed gradually, and it was found that the amount of food input for the next week could be predicted for each day of the week using at least one week of raw food data. Further, a correlation was found between the subsequent change pattern of the type that approximates the change in the amount of garbage for one week and the change in the amount of garbage thereafter. In other words, the garbage input process has the property of a 7-fold Markov process.

  The processor 22 analyzes at least one week of garbage data to determine the next weekly checkpoint, residue removal time, bacteria refill time, bacteria composition, bacteria input, bed refill time, and A schedule for maintenance of the mechanical parts, that is, a maintenance program is created. For example, from the input garbage pattern file 25e shown in FIG. 4, next week, bacteria and fungus beds are added on Wednesday, and the temperature in the stirring tank is set on Monday.

  For this reason, the garbage data from the sensor unit 23 is accumulated in the memory 25 for at least one week, and a similar change pattern type is searched from the garbage data file 25a and the input garbage pattern file 25e. Further, a maintenance program for the next week is created from the type of the searched change pattern and the maintenance data file 25c. Here, as described above, the maintenance data file 25c is filed with periodical inspections, replacement and adjustment of mechanical parts, and usage results data of bacteria composition and amount.

  FIG. 6 is a flowchart showing a maintenance program creation operation of the garbage disposal system. The processor 22 of the garbage processing system starts processing in accordance with the control program file 25i in the memory 25 in step 51. In step 52, the garbage data from the sensor unit 23 is read into the garbage data file 25a in the memory 25.

  Next, in step 53, it is checked whether or not the garbage data file 25a has accumulated one week's worth of data. If not, the garbage data is continuously read. In step 54, the processor 22 checks whether there is a maintenance program in the maintenance program file 25f.

  If there is no maintenance program in the maintenance program file 25f, in step 55, using what data has already been stored in the maintenance data file 25c, what kind of bacteria and fungus bed supplement and mechanism Maintenance and adjustment of the parts are necessary. Therefore, a schedule such as the arrangement of the maintenance inspector, the replenishment of repair parts and bacteria, and the preparation of the fungus bed is created, and the process is completed in step 57.

  If there is a maintenance program in the maintenance program file 25f, the closest maintenance program is selected in step 56 in consideration of conditions such as the user's type of business, scale, waste disposal amount, timing, and weather conditions. In step 57, the schedule creation is completed.

  According to the schedule created in this way, the state of garbage disposal is inspected, residues are removed, bacteria are replenished, fungus beds are replenished, and mechanical parts are maintained. Such maintenance is performed by a dedicated operator who handles the garbage disposal system.

  Garbage data accumulated and analyzed every day is maintained and used on a weekly basis, and at the same time, it is accumulated and analyzed along with the user's industry, scale, region, weather conditions, and seasonal environmental conditions. The garbage patterns are classified and stored in the input garbage pattern file 25e in the memory 25.

  Therefore, in the second embodiment of the present invention, if the input garbage pattern file 25e is prepared in advance, the input garbage pattern that is most approximated by using data for at least one week of the garbage data accumulated and analyzed every day. Is selected from the input garbage pattern file 25e, and the maintenance program file 25f is created based on the pattern.

  The processor 22 analyzes the garbage data for at least one week, searches the input garbage pattern file 25e for a type of a similar change pattern from the input garbage pattern file 25e, and from the type of the searched change pattern, A schedule, that is, a maintenance program, is prepared for the next weekly inspection, residue sampling, bacteria replenishment, bacteria composition, bacteria input, fungus bed replenishment, and mechanical parts maintenance.

  By doing so, long-term maintenance resources and short-term maintenance resources can be prepared. In particular, when the garbage disposal system is installed in various places, it is possible to efficiently arrange maintenance personnel, replenish bacteria and fungi beds, and adjust and maintain mechanical parts.

  In the third embodiment of the present invention, the processor 22 analyzes at least one week of data accumulated in the garbage data file 25a by the input garbage analysis program file 25d, and estimates the pattern according to the user's business type and scale. Then, it is stored in the input garbage pattern file 25e, and the most suitable maintenance program according to the pattern is selected from the maintenance program file 25f, and the stirring mechanism and bacteria are inspected and adjusted according to the input date and weight of the garbage. And replenishment maintenance schedules.

  According to the third embodiment, even if the number of users of the garbage processing system increases or decreases, it is possible to create a maintenance schedule by referring to the pattern according to the business type and scale of the user of the input garbage pattern file 25e. it can.

  FIG. 7 is a network block diagram of the garbage disposal system showing the fourth embodiment of the present invention. In this garbage disposal system network, the garbage disposal systems 61, 62, and 63 and the centralized management system 69 are provided with modems 65, 66, 67, and 68, respectively, to exchange data with each other.

  In the case of this embodiment, there are three garbage disposal systems constituting the network, but more garbage disposal systems can be combined. Moreover, the processing capacity of the garbage processing systems 61, 62, and 63 may be different.

  The configuration of the garbage disposal systems 61, 62 and 63 is basically the same as that of the garbage disposal system shown in FIGS. 1 and 2, and in this embodiment, the same reference numerals as those in FIGS. 1 and 2 are used for convenience. Use to explain each part.

  In the garbage processing systems 61, 62 and 63, the same data processing as in the above-described embodiment is performed. A maintenance schedule is individually created and maintenance is performed, and all data necessary for management is sent to the central management system 69 by a modem and shared with the garbage disposal systems 61, 62 and 63. .

  This centralized management system 69 is composed of almost the same components as the controller of FIG. 2, and includes a processor 22, a memory 25, a display unit 26, and a printer 27.

  This centralized management system 69 collects and accumulates data from the garbage processing systems 61, 62, and 63, and creates the input garbage pattern file 25e and the maintenance program file 25f described above based on the garbage analysis program file 25d. Then, it is sent to the garbage processing systems 61, 62 and 63. Thereby, the garbage processing systems 61, 62, and 63 can search for the maintenance program from the most suitable input pattern.

  However, until the centralized management system 69 creates the input garbage pattern file 25e, it is necessary to accumulate a large amount of data over a long period of time. Until then, the garbage processing systems 61, 62, and 63 are respectively Create a maintenance schedule for the next week with at least one weekly performance data. In this case, for long-term maintenance, common data is read from the main maintenance program file 25f and used.

  The centralized management system 69 exchanges data with the garbage processing systems 61, 62, and 63, and manages which garbage processing system performs when, how much maintenance, and what is required next. can do.

  In the above-described embodiment, data processing is executed mainly based on the weight of the input garbage. However, when data from the load sensor of the sensor unit 23 is used in addition to this, the load sensor detects the activity of bacteria in the agitation tank 13. Since there is a correlation with the degree, a more efficient and accurate maintenance program can be created.

  FIG. 8 is a block diagram of a parallel garbage processing system to which the present invention is applied. This side-by-side garbage disposal system includes a crusher 71, a switching valve 72, a controller 73, and first and second garbage disposal systems 74 and 75.

  The crusher 71, the switching valve 72, and the first and second garbage disposal systems 74 and 75 of this side-by-side garbage disposal system are controlled by the controller 73. This controller has substantially the same configuration as the controller of the above-described embodiment.

  The crusher 71 includes a garbage input port 12, an input port opening / closing unit 24, at least a sensor unit 23 for measuring weight, and a crushing mechanism. The weight of the thrown-in garbage is measured by the sensor unit 23, and the weight data of the garbage is output to the controller 73.

  The controller 73 exchanges data with the first and second garbage processing systems 74 and 75, and grasps how much garbage these systems are processing when garbage is introduced. be able to.

  Further, the controller 73 outputs load data of the respective drive motors 14 detected from the sensor units 23 of the first and second garbage processing systems 74 and 75. Therefore, the processor 73 checks the processing weights of the first and second garbage processing systems 74 and 75 and operates the switching valve 72 so that the processing weights are substantially equal. If the processing weights of the first and second garbage processing systems 74 and 75 are substantially the same, the switching valve 72 is controlled so that the loads are substantially the same.

  Thus, efficiency can be improved by using a plurality of garbage processing systems to increase the garbage processing capacity of the system and controlling the processing to be substantially uniform.

  In such a system as well, as in the above-described embodiment, it is possible to collectively create a maintenance schedule for the side-by-side garbage disposal system based on the accumulated data for one week.

  As described above, the garbage processing system according to the present invention creates and executes a maintenance program based on the processing results for at least one week, and accumulates and analyzes the processing data thus executed to make it more actual. There is a remarkable effect that it is possible to perform appropriate garbage disposal and accurate maintenance inspection.
