The technical solution of this application is applied to the sorting equipment in the working process of mineral dry sorting, through periodic detection, it is determined which nozzles have not been sprayed during the cycle time, and these nozzles are cleaned and sprayed , to spray out the dust particles in the nozzles, so that the blowing equipment does not have to stop working to ensure the cleanliness of each nozzle and ensure the working efficiency.

Next, the technical solution of the present application is described with specific examples.

Example 1

As shown in Figure 1, the blowing equipment cleaning method of the present application comprises the following steps:

Step S100 , taking a predetermined detection time as a cycle, to detect whether each nozzle in the blowing device is in the working state of blowing operation.

The method is applied to the blowing equipment, which is a part of the sorting equipment of the whole mineral dry sorting. The nozzle device cleaning method of the present application is applied during the use of the blowing device, that is, the cleaning method of the blowing device is inserted during the normal operation of the blowing device.

As shown in Figure 2, it is a schematic diagram of the scene of mineral dry separation in this application. The sorting device includes: a camera device 100 , a conveyor belt 200 , a blowing device 300 , a nozzle 400 and a recovery bin 500 . There are multiple nozzles 400, which can be arranged in a line on the blowing equipment 300, or can be arranged on the blowing equipment 300 according to a preset array. The conveyor belt 200 is used to convey materials, and the camera device 100 is used to photograph the The pictures of the materials on the conveyor belt 200 are image-recognized to determine the mineral content of each material. The recovery bin 500 is used for recovering materials.

During mineral dry separation, various mineral materials will be poured on the conveyor belt 200, and will be transported by the transmission mechanism to the recovery bin 500. A camera device 100 is arranged above the conveyor belt 200, and the camera device 100 is used for real-time monitoring and photographing of the conveyor belt 200. and identify the materials on it, distinguishing waste rock from required ore. After the material reaches the end of the conveyor belt 200, it will fly over the injection device 300 in a parabola at the speed of the conveyor belt 200 and arrive at the recovery bin 500, wherein the injection device will control the nozzle 400 to perform corresponding injection according to the identification of the material by the camera device 100 Operation, for example, when the ore that needs to be left flies over the injection device 300, the nozzle 400 will spray, change the flying track of the material to the ore collection area in the recovery bin 500, and then do not spray the waste rock, allowing the waste rock to fall. To the waste rock recycling area, etc. The specific dry method sorting logic is not the focus of this application, and only the explanation of the operating environment is given here, so I won’t repeat it here.

The camera device 100 can be wired or wirelessly connected throughout the sorting equipment, and the images captured by it will be sent to the main control of the sorting equipment (not shown in the figure), and the main control will process and analyze the images, and then send the corresponding The control command is sent to the blowing device 300 to control the nozzle 400 to carry out the blowing operation.

It can be seen that in this scene of the injection equipment, the material will frequently fly over the nozzle 400 . The material is various ores of different sizes. These ores themselves contain a lot of dust debris, so it is easy to leave some dust into the nozzle during the flyover process, causing the nozzle to be blocked.

Step S200, within the detection time, put the nozzles that have not been sprayed into the cleaning queue.

To this end, a detection time can be preset as the detection cycle. The detection time is related to the specific working scene, that is, it is related to the dryness of the material. For the drier material, it is more likely to generate dust, so in a short time. The nozzles are more likely to be clogged with dust, so the detection time needs to be shorter, such as 30 minutes. On the contrary, if the dryness of the material is low, for example, it has been cleaned in the previous steps, so that the material has a little humidity, the probability of the material generating dust to block the nozzle is small, so a longer detection time can be set, such as 2 hours. Therefore, the detection time can be preset according to the dry humidity of the material. When the dryness is high, the detection time is short, and when the humidity is high, the detection time is long.

The detection period can be determined by setting up a timer. Take the detection time of 30 minutes as an example. When the whole sorting equipment starts to run, the timer starts counting. During the timing, the injection equipment is operating normally according to the beneficiation logic , when the timer reaches the detection time, it starts to detect the working status of each nozzle. The timer can be a timing device set on the blowing equipment, or a timing module realized by a program.

As shown in Figure 3, it is a schematic diagram of the relative position between the nozzle and the material. The blowing device 300 is provided with a plurality of nozzles 400, and the conveyor belt 200 has a width, so the material will also be in different positions on the conveyor belt, and the material has its own size, so the size of the material affects the area covered when it flies over the blowing device. number of nozzles. In Figure 3, material 1 and material 2 cover the position of No. 2 nozzle and No. 3 nozzle, so when the material flies over, these two nozzles may perform spraying operations according to the recognition results. In this embodiment, it will be sprayed when it is covered. Similarly, the two materials on the right cover No. 5 nozzle, No. 6 nozzle, No. 4 nozzle and No. 5 nozzle respectively. The equipment can then control the corresponding nozzles to carry out the blowing operation, while No. 1, 7, and 8 nozzles do not need to carry out the blowing operation. It can be seen that the nozzles that are not covered will not perform the blowing operation. Wherein, the numbers of the nozzles in FIG. 3 are used for convenience of description, and the spraying device 300 can control each nozzle 400 by the number of the nozzles, or by other numbers of the nozzles.

Therefore, it can be seen that during the entire detection period, some nozzles may not have been sprayed once. It is understandable that the spraying operation of the nozzles will spray air from the inside of the nozzles. In this case, dust will not enter For nozzles, if there is no air injection for a long time, dust may enter the nozzle and cause harm. For this reason, the working status of each nozzle will be marked, and the nozzle that has sprayed air during the detection period will be recorded as the trigger state , the nozzle that has not sprayed air once will not mark the working status of the nozzle. When the countdown of the timer returns to 0, the working states of all nozzles are traversed to determine the nozzles that have no blowing operation at all during this detection period. It is understandable that the nozzles that have not been sprayed are likely to fall into dust, so they need to be cleaned to ensure safety, so these nozzles will enter the cleaning queue for subsequent cleaning operations.

The cleaning queue is a queue formed when the above-mentioned nozzles without blowing operation at all are identified, that is, in the internal program, these nozzles will be listed as nozzles that need to be cleaned to distinguish them from other nozzles that are working normally queue. Before the cleaning of the nozzles in the cleaning queue is completed, the normal blowing work will not be performed, but the cleaning blowing operation will be performed according to the cleaning logic.

That is to say, the blowing equipment will check all the nozzles every other detection time, and pick out those nozzles that have not been blown into the cleaning queue. Time, determine the specific detection time point, for example, the device is turned on at 2 o'clock, and the detection time is 30 minutes, so the detection time point is 2:30, 3:00, 3:30, etc., and so on, to get all the detection time points, and then in Before the detection time point is reached, the above-mentioned work of marking the working status of each nozzle is carried out. When the detection time point is reached, the corresponding nozzle working state detection is carried out, and the nozzles that are not working are put into the cleaning queue.

The way to mark the working status of the nozzles can be to mark each nozzle individually, or to create a record array according to the number of nozzles. The number of each position defaults to 0. After the nozzle at the corresponding position performs the blowing operation, it will be The number of this position is set to 1, indicating that it has been sprayed. Then when the detection time is reached, all nozzles with a value of 0 will be put into the cleaning queue.

In addition, after the arrival detection period is detected, the state of each nozzle will be reset, that is, those marked as triggered will cancel the mark and become untriggered, and 1 will be changed back to 0. This starts the detection of the next cycle.

Step S300, monitor the materials on the conveyor belt in real time, respectively determine the cleaning timing of each nozzle in the cleaning queue according to the distribution of the materials on the conveyor belt, and control each nozzle to perform cleaning and blowing operations at their respective cleaning timings until the cleaning queue All nozzles in have been subjected to the cleaning and blowing operation described above.

After the nozzles in the cleaning queue are determined, these nozzles need to be cleaned, but because the current equipment is in normal working condition, these nozzles cannot interfere with the normal work when cleaning and blowing operations, so it needs to be cleaned according to the material The position and coverage of each nozzle are determined to determine the cleaning timing of each nozzle.

For each nozzle, cleaning and blowing requires the nozzle to blow for a certain period of time to ensure that all the dust is blown out. The time used for cleaning and blowing can be customized according to experience. It is understandable that if the time is too long, resources will be wasted, and if the time is too short, it may not be effective, so an appropriate time length should be selected.

Therefore, the relative position and coverage of the material and the blowing equipment can be obtained first through the camera device to determine the idle time period of each nozzle in the cleaning queue, if the length of the idle time period is longer than the cleaning blowing operation time, the start time of the idle time period is the cleaning timing of the corresponding nozzle.

As shown in Figure 3, we can simply understand the distribution of the material, that is, the position of the material on the conveyor belt, and the distance between the material and the nozzle, combined with the size of the material itself, we can determine the nozzle that will be blocked by the material.

Among them, the camera device shoots images of materials, and for these images, a binarization operation is performed first, and then the regions of interest related to the materials in these images are obtained, and images of individual materials are obtained from these regions of interest Features, the way to obtain image features in this embodiment can be obtained through Blob (foreground/background separation) analysis, so that the position of each material can be obtained, and the position of the blowing device is fixed, so each material can be obtained The relative position with the blowing equipment.

It can be understood that if the nozzles in the cleaning queue have material flying over during the cleaning injection, it may cause false blowing, so when there is material flying over, the cleaning injection cannot be performed.

Therefore, it is necessary to determine the cleaning timing of each nozzle. Taking No. 1, No. 3, and No. 5 nozzles in the cleaning queue as examples, how to determine the cleaning timing is explained respectively.

In Figure 3, there is no material at the position corresponding to No. 1 nozzle. Therefore, for No. 1 nozzle, there will be no material flying over for a long time in the future, so there is no need to worry about the cleaning and blowing operation. The material was sprayed by mistake, so for the No. 1 nozzle, the cleaning injection operation can be carried out now. Therefore, the idle time period of No. 1 nozzle can be regarded as all time periods, and the cleaning and blowing operation of No. 1 nozzle can be started immediately.

No. 3 nozzle is covered by material 1 and material 2. Because the positions of the two materials are obtained through the above-mentioned image processing, the distance between No. 3 nozzle and material 1 and material 2 can be obtained, and the speed of the conveyor belt for transporting materials is constant. Known, so the time point when material 1 and material 2 reach the top of nozzle 3 can be calculated. It can be understood that when the time point is obtained, the time interval is obtained. For example, within the interval formed by the current time point and the time point when material 1 reaches the top of nozzle 3, there will be no material flying over nozzle 3. This time The interval is the idle time period of the nozzle 3. Similarly, the interval formed by the time point when the material 1 and the material 2 reach above the nozzle 3 is also the idle time period at the other end. It can be understood that when the idle time period is longer than the time required for the cleaning and blowing operation, the cleaning and blowing operation can be performed at the beginning of the time period.

For example, if the time required for the material 1 to reach the top of the nozzle 3 is longer than the time required for the cleaning and spraying operation, the nozzle 3 can directly perform the cleaning and spraying operation. If the time required for the material 1 to reach the top of the nozzle 3 is less than the time required for the spray cleaning operation, the cleaning and spraying operation cannot be performed for the nozzle 3, and the cleaning time has not yet arrived, and the idle time formed by the material 1 and the material 2 If the period is longer than the time required for the cleaning and blowing operation, it is necessary to wait for the material 1 to fly before the cleaning and blowing operation can be performed.

For No. 5 nozzle, similar to No. 3 nozzle, it is covered by material 3 and material 4. The idle time period at both ends can also be calculated to determine the cleaning timing of No. 5 nozzle. The logic of the two is the same, so I won’t repeat them here.

Therefore, if the nozzle is not within the coverage range, the idle time period of the nozzle is all time; if the nozzle is within the coverage range, then the position of the material between the nozzle and the corresponding material According to the moving speed of the material, determine the time point when each material covering the nozzle reaches the top of the nozzle, and the interval formed by the time point when two adjacent materials reach the top of the nozzle is the nozzle idle time period.

Obviously, during the cleaning operation above, other nozzles can work normally without being affected by these nozzles, and there is no need to stop the conveyor belt. It can be seen from the screening method that the nozzles with low probability of being triggered are screened out, that is, the nozzles at this position are less covered by materials, so they will not spray air during the detection cycle, so these nozzles will also be sprayed when cleaning. There is a high probability that the cleaning operation can be carried out immediately, so the entire detection and cleaning operation can be carried out quickly without interfering with the normal sorting work, so that the nozzle can be cleaned without stopping the machine, increasing the continuous working time of the machine, Thereby increasing the working efficiency of the machine.
