Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hydrate drying apparatus that evaporates the water content of hydrates by using heat generated in a metal by electromagnetic induction.

[0002]

2. Description of the Related Art As a conventional apparatus of this type, an apparatus for blowing air heated to a high temperature using an electric heater to a water-containing material to evaporate water, for example, a clothes drying device or a garbage drying device, or containing a water-containing material. 2. Description of the Related Art There is a device for heating a metal storage unit with an electric heater to heat the storage unit to a high temperature and evaporating the water content of a water-containing material using conduction heat or radiation heat, for example, a garbage drying device.

[0003]

However, the conventional clothes drying apparatus uses a hot air of about 75 ° C. for drying.
When garments are entangled with each other, the flow of warm air is hindered, and it is difficult to promote the drying of the entangled portions, so that it takes a long time to finish the drying.

Further, the garbage drying apparatus blows hot air of more than 100 ° C. on the garbage to promote evaporation because the garbage contains a lot of water, or heats the storage section to a high temperature of more than 100 ° C. However, it is difficult to uniformly dry the whole garbage, and the same heat is supplied to the part where the drying is promoted, so that the area is scorched and sticks to the storage part. In the method of heating the storage portion to a high temperature, the sticking to the storage portion acts to hinder the heat transfer performance, and the drying ability is reduced due to a decrease in drying ability, resulting in a longer drying process. Further, when the user cleans the storage unit, there is a risk that the storage unit may be mechanically damaged due to stubborn sticking. To solve this problem, in the latter stage of the drying process, if a method of controlling the amount of heat to be supplied to suppress burning and sticking is employed, the drying process requires a longer time.

The present invention provides a hydrate drying apparatus that evaporates the water content of hydrates by using heat generated in a metal by electromagnetic induction, which suppresses local abnormal heating and shortens the drying processing time. is there.

[0006]

In order to solve the above-mentioned problems, the hydrate drying apparatus of the present invention has a storage portion made of a non-metallic material for storing a hydrate, and a bonding portion provided outside the storage portion. A metal portion made of a plywood of at least a magnetically damping metal material and a low magnetic permeability and low resistivity metal material, and an electromagnetic induction heating coil provided outside the housing portion and provided to face the magnetically damping metal material of the metal portion. It has.

According to the present invention, the magnetically damped metallic material facing the electromagnetic induction heating coil is heated by electromagnetic induction heating and generates heat, and the generated heat is transferred to the storage portion made of the low magnetic permeability and low resistivity material and the nonmetallic material. The heat is transferred to the hydrated material to evaporate the water content of the hydrated product. When the water content of the hydrate decreases, the amount of heat transfer to the hydrate decreases, so that the temperature of the magnetically susceptible metal material increases, and the temperature of the magnetically permeable material reaches the Curie temperature of the material. When the magnetically damped metal material reaches the Curie temperature, heat generation is self-controlled and local abnormal heating can be suppressed. Therefore, the maximum amount of heat transfer can always be supplied from the metal part to the hydrated side without causing abnormal damage to the storage part of the nonmetallic material and causing mechanical damage, and the drying time can be reduced.

The storage section 12 having the above-mentioned various members attached thereto.
Is stored and placed inside a cylindrical resin guide container 17 having a substantially concentric shape with the storage section 12. Thereby, the rotating shaft of the rotary blade 14 of the stirring means is connected to the power system. The clearance between the metal part 15 provided in the storage part 12 and the resin guide container 17 is at most several mm.

An electromagnetic induction heating coil 18 is disposed below the bottom surface of the resin-made guide container 17 so as to face a magnetically damping metal material 15a which is a lower layer of the metal portion 15. Reference numerals 19 and 20 denote sintered ferrite materials, which act to limit the space in which magnetic flux generated when a high-frequency current flows through the electromagnetic induction heating coil 18 is diverted. Reference numeral 21 denotes a heating coil drive power supply for supplying a high-frequency current to the electromagnetic induction heating coil 18.

The electromagnetic induction heating coil 18 has a configuration in which the heating coil is wound circumferentially so that an induced current flows substantially parallel to the longitudinal direction of the slit of the opening 16 provided in the metal portion 15. Thereby, the flow of the induced current generated in the metal portion 15 is not cut by the opening portion 16, and the high-frequency magnetic coupling with the electromagnetic induction heating coil 18 can be maintained in a good state, so that the metal portion 15 efficiently generates heat. be able to. In addition, a power transmission unit that rotationally drives the rotary wings 14 of the stirring means is disposed at the center of the plane space where the electromagnetic induction heating coil 18 is disposed. A rotary drive gear 22 is provided at one end of the power transmission unit, and a drive motor 2 serving as a power source is provided.
The power is transmitted by being connected to a gear 24 provided on the output shaft 3 and a belt 25.

The power transmitted to the rotary drive gear 22 is transmitted to the stirring means 14 via a rotary shaft 26 and a rotary shaft 27 which is connected to the rotary shaft 26 by fitting and assembling. The rotating shaft 27 and the stirring means 14 are fixed to the pedestal 29 by tightening a nut 28 assembled at one end of the rotating shaft 27.

Reference numeral 32 denotes a suction fan for discharging the water vapor generated from the garbage to the outside of the apparatus. The suction port 32a is connected to an exhaust port 33 provided on the opening / closing door 11 at the upper part of the storage section 12. A spiral sheathed heater 34 and a deodorizing catalyst 35 are provided at the end of the discharge port 32b of the suction fan 32. The exhaust air containing water vapor generated from the garbage sucked by the suction fan 32 is supplied to the sheath heater 3.
4, the temperature is raised to the temperature in the catalyst activation temperature zone, and the deodorizing catalyst 35 oxidizes the odor in the exhaust air. The exhaust air from which the odor has been removed is discharged out of the device.

Above the storage section 12, a fan motor 36 provided on the opening and closing door 11, a blade 37 rotated by the fan motor 36, and a ring-shaped sheath heater 38
It has. 39 is a blade 37 and a sheath heater 38
The protective housing 39 has a large number of openings on a surface facing garbage. The central part of the opening surface 40 of the protective housing 39 is an opening 41 for suction, and the peripheral part is an opening 42 for discharging. As a result, air or water containing water vapor in the storage section 12 is sucked through the suction hole 41, heated by the sheath heater 38, and discharged into the storage section 12 through the discharge hole 42. Due to this flow, the storage unit 12
A circulating flow of air containing water vapor is generated therein. Drying of the garbage is further promoted by receiving heat from the circulation stream. The flow rate of exhaust gas from the storage section 12 by the suction fan 32 is set to about 1/10 of the circulating flow rate. Reference numeral 43 denotes a support for the apparatus main body.

The operation and operation of the hydrate drying apparatus of the present invention having the above configuration will be described below. Garbage, door 11
Is lifted upward and put into the storage section 12. The garbage can be input only once or can be divided into several times.

When there is no more garbage to be put into the storage section 12 or when the inside of the storage section 12 is full of garbage, drying processing of the put garbage is performed. This process is started when the user presses a drying process start button (not shown) provided on the apparatus main body. At the start of the drying, it is possible to control the closed state of the opening / closing door 11 and to execute the drying start. Door 11
Is in the open state, the flow of the circulating flow is disturbed and the heat received from the circulating flow is reduced, so that the drying process is in an unfavorable state.

With the start of drying, electric power is supplied to the heating coil drive power supply unit 21, the drive motor 23, the fan motor 36, and the sheathed heaters 34 and 38, and each starts operation. A high-frequency current is supplied to the electromagnetic induction heating coil 18. An induced current flows through the magnetically damped metallic material 15a magnetically coupled to the electromagnetic induction heating coil 18 to generate heat. The heat of the magnetically damped metal material 15a is transferred to the garbage via the low magnetic permeability and low resistivity metal material 15b and the non-metal material forming the bottom surface 12a of the storage section 12. The water contained in the garbage in the initial stage of heating rises to a temperature of 100 degrees by this heating. On the other hand, about 130 degrees of warm air heated by the sheath heater 38 is blown from above the storage section 12 above the garbage, so that the garbage is heated from both the upper and lower sides and rises in temperature. The agitating means 14 is also driven to rotate at the beginning of the heating, but the driving may be stopped until steam starts to be generated from the garbage as described below.

After a predetermined time, steam starts to be generated from the garbage. The suction fan 32 is driven from this timing. This timing is determined based on a preset time or the operating power of the heating coil drive power supply unit 21. As a result, the generated steam is discharged out of the apparatus via the deodorizing catalyst 35 as needed.

As the heating progresses, the water content of the garbage gradually decreases. It is difficult to dry the garbage uniformly, but the dried garbage is reduced in weight and moves well under the influence of the hot air circulating flow and the rotation of the stirring means 14. For this reason, since the progress of drying is slow and the heavy garbage comes into contact with the bottom surface 12a of the storage section 12, heat transfer is applied from below, and drying proceeds efficiently.

The amount of heat transferred to the garbage is substantially proportional to the garbage contact area on the bottom surface 12a of the storage unit facing the metal part 15, but as drying proceeds, the contact area of the garbage with the storage unit bottom surface 12a decreases. As a result, the amount of heat received by the garbage from the metal portion 15 decreases. Accordingly, the temperature of the metal portion 15 gradually increases, and the magnetically damped metal material 15a partially reaches the Curie temperature of the material. The magnetic permeability of the anti-magnetic metal material in the region where the Curie temperature has been reached is reduced, the amount of induced current flowing is reduced, and heat generation is suppressed. The electromagnetic induction heating coil 18
Since the high-frequency current flowing through the coil is uniform over the entire length of the coil, the reduced amount of the induced current flowing through the anti-magnetic metal material flows through the low-permeability metal material 15b. Low permeability metal material 15
Since b is made of a material having low magnetic permeability and low resistivity, it has a small resistance value with respect to the induced current and hardly generates heat.

Accordingly, as the drying proceeds, the calorific value of the metal portion 15 is automatically suppressed, and the dried garbage is not further heated and burnt. Further, since the storage section 12 is made of a resin material which is a non-metallic material, the storage section 12 does not transmit heat to a wide range due to the heat generated by the metal section 15.
Is predominantly heated by the hot air circulating flow. Therefore, the dried garbage is not abnormally heated, and the inner wall of the storage section 12 does not stick.

As described above, the calorific value of the metal part 15 changes with the progress of temperature drying, while the metal part 15 thermally expands as the temperature rises to a Curie temperature of about 150 ° C. The difference in the coefficient of thermal expansion between the magnetically damped metal material 15a and the low magnetic permeability and low resistivity material 15b causes the metal portion 15 to warp. In addition, due to the difference in the coefficient of thermal expansion of the non-metallic material of the storage part 12, there is a danger that the warpage of the metal part 15 may cause the joint between the metal part 15 and the storage part bottom surface 12 a to separate and lower the heat transfer performance. The group of apertures 16 arranged in the portion 15 absorbs the thermal expansion of the metal portion 15 and suppresses the thermal warpage of the metal portion 15, thereby maintaining a good connection state between the metal portion 15 and the storage portion bottom surface 12 a and transmitting the heat. Thermal performance is guaranteed. In addition, although the metal part 15 is adhesively bonded to the storage part bottom surface 12a,
Screw 4 as shown in the figure considering the drying and curing time of the adhesive
4 is accompanied by mechanical assembly. By the structure and assembling method of the metal part 15 described above, a structure for directly and stably transferring the heat generated by the metal part 15 to the storage part 12 made of a non-metallic material is ensured, thereby shortening the drying time of the garbage. Can be achieved.

Further, the progress of drying of the garbage causes a decrease in the operating power of the heating coil drive power supply unit 21 due to the above-mentioned change in the characteristics of the magnetically damped metal material. For this reason, the drying progress can be detected based on the change in the operating power of the heating coil drive power supply unit 21. Then, based on the drying progress information, the flow rate of the hot air circulating flow is increased,
8 can be reduced or stopped.

Accordingly, by controlling the temperature of the side wall surface of the storage section 12 where heating by the hot air circulation flow is dominant to about 120 ° C. or less, dry garbage contacting the wall surface of the storage section 12 is removed from the storage section 12. Is not heated to a higher temperature by the heat reception, and sticking to the storage section can be suppressed. Further, when such a state is reached, the suction capacity of the suction fan 32 is increased, so that the pressure in the storage section 12 is reduced, and the discharge of water vapor can be further promoted. By performing such control, the drying processing time can be reduced.

The end of the drying is executed based on the information of the heating coil drive power supply section 21 described above, whereby the drying performance of the apparatus can be assured independently of the amount of garbage input.

When taking out the dried refuse from the storage section 12, the storage section 12 is configured to be detachable, and
2 is removed from the apparatus main body, and the contents are transferred to a box or a bag. Dry garbage may be powdered, and when mainly handling this kind of garbage, the dry garbage of the powder is removed from the storage section 12 by suctioning with a vacuum cleaner and easily stored in a garbage bag. be able to. Furthermore, in the case where the storage unit 12 is configured to be detachable, the convenience that the storage unit 12 can be easily washed with water can be provided.

(Embodiment 2) Next, Embodiment 2 of the present invention will be described with reference to FIG.
This will be described with reference to FIG. The second embodiment is different from the first embodiment in that a metal part 45 to be joined and assembled to the bottom surface 12a of the storage part 12 is used.
Is constituted by a plurality of metal pieces 45a and 45b divided from each other. A metal piece cover 46 made of a resin material that covers the metal pieces is provided below the metal pieces 45a and 45b, and a plurality of metal pieces 4 are provided on the bottom surface 12a of the storage unit 12.
A projection 47 functioning as a guide for arranging 5a and 45b at predetermined positions is provided. This projection 47
Is screwed, and is supported and fixed by screws 48 so that the metal piece cover 46 presses the metal pieces 45a and 45b toward the storage unit bottom surface 12a.

The metal pieces 45a and 45b have a substantially concentric shape. With this configuration, the gaps 49 (the projections 47 are present in the gaps) between the metal pieces cut off the flow of induced current generated in the metal pieces by the electromagnetic induction heating coil wound substantially concentrically. do not do. As a result, each of the metal pieces 45a and 45b is efficiently heated by the electromagnetic induction heating coil. Further, the metal portion 45 heated to a high temperature undergoes thermal expansion, but the configuration in which the metal portion is divided into a plurality of metal pieces allows thermal expansion to be dispersed in each metal piece, and the non-metallic resin It is possible to stably maintain the joining state between the storage section bottom surface 12a formed of the material and the metal piece, secure the heat transfer performance from the metal piece to the storage section bottom face, and shorten the drying processing time.

The configuration of the metal pieces is such that a disk or a donut-shaped metal piece is arranged circumferentially, and a small wound electromagnetic induction heating coil is arranged to face each metal piece. Is also good.

Further, a plurality of storage portion support feet 59 are formed at the peripheral edge of the bottom surface of the storage portion 50.
An opening 60 through which the storage portion support foot 59 can be inserted is provided.

In the above configuration, the provision of the reinforcing portion 51 for reinforcing at least the bottom surface 50a of the storage portion 50 made of a non-metallic material enables the mechanical strength of the storage portion to be ensured. For example, it is possible to realize a detachable storage section configuration or an increase in the size of the storage section, for example, a size that can store 10 to 20 kg of garbage that can be dried in one operation.

Also, by ensuring the mechanical strength of the bottom surface of the storage section 50 by the reinforcing section 51, the thickness of the material of the storage section bottom surface 50a can be reduced. Thereby, the generated heat of the metal part 52 can be transferred to the hydrated substance in the storage part with high heat transfer characteristics,
The drying time can be reduced.

The fixed wings 57 are fixedly arranged on the inner surface of the storage section by a fixing tool 58 penetrating the reinforcing section 51 and the storage section 50, so that the reinforcing section 51 and the storage section 50 are mechanically fixed by the fixing tool 58. It is possible to securely assemble and fix the storage section mechanically. As a result, the material thickness of the storage unit bottom surface 50a can be made smaller, the heat transfer performance from the metal unit 52 can be further increased, and the drying time can be further reduced.

The storage unit 50 is formed integrally and is supported by storage unit support feet 59 provided on the periphery of the bottom surface of the storage unit, so that when the storage unit 50 is placed on the floor, for example,
The impact that the storage unit 50 receives from the floor during mounting is reduced by the storage unit support feet 59 made of a non-metallic material, so that the mechanical strength of the storage unit 50 can be secured. Accordingly, the storage unit 50 can be configured to be detachable, and the convenience of the device can be improved.

The peripheral portion of the metal portion 52 is fixedly supported on the reinforcing portion by the metal material of the reinforcing portion 51.
Numeral 1 secures the mechanical strength of the storage section 50 and functions as a fixed support member for the metal section 52, so that the number of components can be reduced and the weight of the storage section can be reduced. Therefore, the heat transfer performance of the storage unit 50 is ensured, and a highly convenient storage unit having portability can be provided.
