In order that those skilled in the art will better understand the present application, a technical solution in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in which it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present application without making any inventive effort, shall fall within the scope of the present application.

It should be noted that the terms "first," "second," and the like in the description and the claims of the present invention and the above figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1 is a schematic block diagram of a multi-target sorting control system according to an embodiment of the present invention, which is based on the multi-target sorting control system illustrated in fig. 1, including: the conveyor 102, the detector 104, the first blowing mechanism 106, the second blowing mechanism 108, the first dividing plate 110, the second dividing plate 112, and the controller 114,

The first blowing parameters set by the first blowing mechanism 106 include a first pressure parameter and a first solenoid valve flow parameter, the second blowing parameters set by the second blowing mechanism 108 include a second pressure parameter and a second solenoid valve flow parameter, the flow parameter of the first solenoid valve is obtained based on the first pressure parameter and a predetermined upper particle size range limit of the target to be sorted, and the flow parameter of the second solenoid valve is obtained based on the second pressure parameter and the predetermined upper particle size range limit;

the conveying device 102 is connected to the controller 114, and is configured to send the objects to be sorted to a blowing position where the first blowing mechanism 106 and the second blowing mechanism 108 are disposed, using a predetermined conveying speed in response to a conveying instruction of the controller 114;

the detection device 104 is connected to the controller 114, and is configured to detect the target to be sorted, obtain a detection result, and send the detection result to the controller 114;

the controller 114 is connected to the first blowing mechanism 106 and the second blowing mechanism 108, and is configured to receive the detection result, and determine a blowing control strategy for controlling the first blowing mechanism 106 and the second blowing mechanism 108 based on the target information of the targets to be sorted indicated by the detection result;

The first blowing mechanism 106 and the second blowing mechanism 108 are configured to perform blowing processing indicated by the blowing control policy on the target to be sorted in response to a blowing instruction of the controller 114, so that the target to be sorted is sorted into a corresponding region among a plurality of sorting regions, where the region corresponding to the target to be sorted is determined by the controller 114 based on the target information, and the plurality of sorting regions is determined based on the first dividing plate 110 and the second dividing plate 112.

It will be appreciated that the first blowing parameters set by the first blowing mechanism and the second blowing parameters set by the second blowing mechanism in the system described above are associated with a predetermined particle size range. In general, the particle size of the object to be sorted belongs to a characteristic particle size range, objects with large particle size difference are sorted together, and accurate sorting results are difficult, and the pre-sorting step can be set so that the particle size of the object to be sorted is in a predetermined particle size range. And the conveying device can adopt a preset conveying speed to convey the objects to be sorted, so that the objects to be sorted reach the blowing position at the initial speed. The objects to be sorted on the conveying equipment are detected by the detecting equipment, and the detection result is sent to the controller. The controller controls the first blowing mechanism and the second blowing mechanism to execute the blowing process, and determines a blowing control strategy based on target information indicated by the detection result. The blowing instruction of the controller comprises the blowing control strategy, and the first blowing mechanism and/or the second blowing mechanism enable the targets to be sorted into the corresponding areas according to blowing treatment indicated by the blowing control strategy.

Optionally, the first electromagnetic valve flow parameter and the second electromagnetic valve flow parameter belong to the coefficient flow (CV value for short) of the electromagnetic valve, and are a measure for measuring the flow performance of the electromagnetic valve, and are used for indicating the basic flow capacity of the electromagnetic valve and measuring the flow performance of the electromagnetic valve under each design pressure. The CV value is determined by the internal flow path configuration of the solenoid valve and its dimensions, and also varies with ambient temperature, i.e., pressure. In one alternative, to calculate the CV value of the solenoid valve, a flow-to-pressure conversion equation may be used:where Q represents the amount of gas that can flow per second, K represents the CV value of the solenoid valve, P1 represents the inlet valve end pressure, and P2 represents the valve end pressure. In most cases P2 can be close to 0 when the solenoid valve is open, the above formula is simplified to +.>Further, the CV value of the corresponding solenoid valve can be obtained.

In the multi-target sorting control system provided by the embodiment of the invention, a conveying device 102, a detecting device 104, a first blowing mechanism 106, a second blowing mechanism 108, a first dividing plate 110, a second dividing plate 112 and a controller 114 are arranged. The method achieves the aim of reducing the possibility of mismatch caused by special shape of the object blocks, achieves the technical effect of improving the accuracy of target sorting, and further solves the technical problem of non-ideal accuracy of target sorting in the related technology.

In an alternative embodiment, the position of the first dividing plate is determined based on a first type of object block and the first pressure parameter, the second dividing plate is determined based on a second type of object block and the second pressure parameter, the second pressure parameter is determined based on a third type of object block and the first dividing plate, the first type of object block belongs to a first type of object, the second type of object block and the third type of object block belong to a second type of object, the objects to be sorted comprise a first type of object and a second type of object, wherein the first type of object block is a multi-type object block comprising the first type of object, and the object blocks with the closest horizontal distance travel under the condition of respectively receiving a preset first blowing force; the second type object block is a multi-type object block which is included in the second type object, and the object block with the closest horizontal distance is moved under the condition of respectively receiving preset second blowing force; the third type object block is one of the plurality of types of object blocks included in the second type object, which has the farthest horizontal travel distance when receiving the predetermined second blowing force.

It will be appreciated that the first dividing plate is defined in relation to the first mass of the first type and the first pressure parameter of the first blowing mechanism and the second dividing plate is defined in relation to the second mass of the second type and the second pressure parameter of the second blowing mechanism. By means of the block shape, the blowing parameters and the mutual coupling factors between the arrangement of the dividing plates, the arrangement of the dividing plates can be made to be more accurate. The first, second and third type blocks have different blowing force driving capacities and influence the positions of the first dividing plate and the second dividing plate based on the correlation of the blocks and blowing parameters, so that the first, second and third type blocks are not subjectively selected and are regarded as blocks with certain typical characteristics. The first type object blocks belong to a first type object, the first type object blocks comprise multiple type object blocks, the object blocks with the closest horizontal travelling distance under the condition of respectively receiving preset first blowing force are selected and considered to represent the object blocks which are most difficult to blow in the first type object, a critical position is determined according to the first type object blocks and first blowing parameters, and then the position of the first dividing plate is determined. Similarly, the second type object block and the third type object block belong to a second type object different from the first type object, the typical characteristics represented by the second type object block and the third type object block are different, the second type object block is the object block with the closest horizontal distance among the multiple type object blocks included in the second type object under the condition of the preset second blowing force, the second type object block is considered to be the object block with the most difficult horizontal distance among the second type object, and the third type object block is the object block with the farthest horizontal distance among the multiple type object blocks included in the second type object, and the object block is considered to be the object block with the most easy horizontal distance among the second type object. Through the arrangement of the object blocks, the object blocks of the specific type can represent the capability of being driven by the blowing force in the object of the corresponding type, the object blocks which are represented and are most difficult to blow and are most easy to blow are determined, and after the object blocks are matched with the preset transmission speed, the first blowing parameters and other influencing factors, the position accuracy of the first dividing plate and the second dividing plate is better, and the problem of mismatching caused by the fact that the object blocks are driven by the blowing force in a special mode can be avoided to the greatest extent.

It should be noted that, because the objects possibly included in the same kind of objects have different sizes and shapes, the same blowing force is applied to objects with different shapes, and the blowing effect actually caused is not the same, the same kind of objects can be blown into different sorting areas. In the related art, the shape of the sorted object blocks, the setting of the blowing parameters and the mutual coupling factor between the sorting areas are not considered, and the matching adjustment of the factors is not involved, so that the problem that some objects with shapes which are easy to blow or objects which are difficult to blow are mismatched into other sorting areas in the similar sorting targets, and the sorting mismatch is caused is solved. The multi-type object blocks included in the first type object respectively represent the object blocks with different common blowing capability driving capabilities in the first type object, and the object blocks can be selected according to the appearance types of the historic object blocks in the first type object. The first type of mass may preferably be set as a specific cube mass in the first type of object as the ideal mass that is most difficult to blow. Similarly, the multi-type object blocks included in the second type object also respectively represent the object blocks with different driving capacities under the blowing capability commonly found in the second type object, the second type object block can be preferably set as a specific cube object block in the second type object, and the third object block is set as a specific flat object block in the second type object.

In an alternative embodiment, the objects to be sorted include a first type of object, a second type of object, and a third type of object, and the plurality of sorting areas include at least one of: a first region, a second region, and a third region, wherein the first region is a region between the first dividing plate and a predetermined region distal boundary, and is used for sorting the first type of targets; the second area is an area between the first dividing plate and the second dividing plate and is used for dividing the second type of targets; the third region is a region between the second dividing plate and a proximal boundary of a predetermined region, and is used for sorting the third type of objects.

It will be appreciated that in sorting, the object to be sorted is to be sorted into a sorting area corresponding thereto, and the plurality of sorting areas may include at least one of: the first region, the second region, and the third region, which are regarded as combinations among one or more of the first region, the second region, and the third region, may be set according to specific requirements. The first area is used for sorting objects to be sorted into a first type of objects, is the area farthest from the spraying position in the sorting areas, and is arranged as an area between the first dividing plate and the distal end boundary of the preset area. The second area is used for sorting objects to be sorted into a second type of objects, and is arranged as an area between the first dividing plate and the second dividing plate.

The second type of object sorted in the second region in the related art often causes mismatching into the first region or the third region due to improper set blowing parameters. In this embodiment, the first dividing plate is determined based on the first type object block and the first blowing parameter, and the second dividing plate is determined based on the second type object block and the second blowing parameter, so that a second area formed between the first dividing plate and the second dividing plate is coupled with the shape of the object block (that is, the driving capability of the blown object is affected) and the corresponding blowing parameter, and the sorting accuracy of the second type object is improved. The third area is used for sorting objects to be sorted into a third type of objects, is an area with the nearest blowing position in a plurality of sorting areas, is arranged as an area between the second dividing plate and the near-end boundary of a preset area, often adopts a mode without blowing, freely falls into the third area, and is difficult to directly mismatch into the second area by virtue of transmission inertia due to the fact that the objects to be sorted are not subjected to blowing treatment. Through the above region arrangement, a plurality of sorting regions can have a plurality of combination modes, corresponding region arrangement can be carried out according to the category number included in a specific target to be sorted, and the mismatch rate of the target to be sorted is reduced through setting the parameter coupling modes of the first dividing plate and the second dividing plate.

Alternatively, the plurality of sorting areas may be provided in the form of a chute. The global zone boundary of the plurality of sorting zones is a zone distal boundary away from the blowing location, and the global zone boundary is a zone proximal boundary near the blowing location, and it is understood that the zone distal boundary and the zone proximal boundary do not change with a change in the zone defined by the first dividing plate and the second dividing plate.

In an alternative embodiment, the first blowing mechanism includes a plurality of first nozzles, and first solenoid valves corresponding to the plurality of first nozzles, respectively, the first solenoid valves are set to the first solenoid valve flow parameters, the second blowing mechanism includes a plurality of second nozzles, and second solenoid valves corresponding to the plurality of second nozzles, respectively, the second solenoid valves are set to the second solenoid valve flow parameters, the plurality of first nozzles are arranged in a single row, and the plurality of second nozzles are arranged in a single row, and the plurality of first nozzles and the plurality of second nozzles are arranged in the blowing position in a side-by-side manner.

It will be appreciated that the first blowing mechanism includes a plurality of first nozzles, each having a respective first solenoid valve, and the first solenoid valves corresponding to the plurality of first nozzles are set as the first solenoid valve flow parameters. Similarly, the second blowing mechanism includes a plurality of second nozzles, each second nozzle has a respective second solenoid valve, and the second solenoid valves corresponding to the plurality of second nozzles are set as second solenoid valve flow parameters. Because the conveying equipment has width, in order to ensure that the objects to be sorted, which are conveyed by the conveying equipment in the width direction, can be uniformly stressed, the first nozzles are arranged in a single row, the second nozzles are also arranged in a single row, the two rows of nozzles are arranged in a front-back side-by-side manner and are in a spraying position, and the front-back positions of the two rows of nozzles can be set according to specific requirements.

In an alternative embodiment, the first pressure parameter is obtained based on the predetermined particle size range, the predetermined transport speed, and a predetermined first air supply pressure range, wherein the first air supply pressure range is a supporting pressure range of a first air supply pipe corresponding to the first blowing mechanism; the second pressure parameter is obtained based on the predetermined particle size range, the predetermined transport speed, and a predetermined second air supply pressure range, the first air supply pressure range being greater than the second air supply pressure range, wherein the second air supply pressure range is a support pressure range of a second air supply pipe corresponding to the second blowing mechanism.

It will be appreciated that in addition to the influence of the characteristics of the mass itself (including particle size, shape, etc.), the precision of the sorting is also influenced by the nozzle selection, the first pressure parameter being based on the predetermined particle size range, the predetermined transport speed, and the predetermined first air supply pressure range, the second pressure parameter being based on the predetermined particle size range, the predetermined transport speed, and the predetermined second air supply pressure range, the first air supply pressure range being greater than the second air supply pressure range. By the nozzle model selection setting, the granularity range, the transmission speed and the supportable air supply pressure are taken as the basis for nozzle model selection, and the first blowing mechanism and the second blowing mechanism which are favorable for setting are coupled with the targets to be sorted.

Optionally, selecting a first nozzle which is matched and is set in the first blowing mechanism from a plurality of preset candidate nozzles according to the first pressure parameter, and selecting a second nozzle which is matched and is set in the second blowing mechanism from the plurality of preset candidate nozzles according to the second pressure parameter.

An adjustable pressure relief valve is mounted on the first supply line to control a first pressure parameter in the first blowing mechanism. An adjustable pressure relief valve is mounted on the second supply line to control a second pressure parameter in the second blowing mechanism. The first pressure parameter is a preferred parameter determined for the first supply pressure range and the second pressure parameter is a preferred parameter determined for the second supply pressure range.

Alternatively, the first air supply pressure is preferably set to be in the range of 0.8MPa to 1.0MPa (megapascals) and the second air supply pressure is preferably set to be in the range of 0.5 MPa to 0.8 MPa.

it can be understood that the multi-target sorting control method provided in this embodiment is applied to the multi-target sorting control system described above, and is the same as the arrangement of the first dividing plate and the second dividing plate in the system. The conveying equipment responds to the conveying instruction of the controller to start conveying the objects to be sorted to the spraying position, the conveying equipment adopts preset conveying speed matched with the spraying parameters and the positions of the dividing plates, the preset conveying speed is required to be changed at will, the duration of the objects to be sorted in the spraying position, namely the duration of the spraying stress, is determined, and the objects to be sorted are closely related to the sorting accuracy, so that after the first dividing plate and the second dividing plate are fixed, the conveying speed of the conveying equipment is the fixed preset conveying speed.

It should be noted that, the first type object block, the second type object block, the third type object block, and the objects to be sorted when sorting is actually performed all have initial speeds, because the objects to be sorted are all transported by the transport device at a predetermined transport speed, and the transport speed used when sorting the objects to be sorted actually is required to be consistent with the transport speed of the transport device when the first dividing plate and the second dividing plate are adjusted, that is, the transport speeds are all predetermined transport speeds. This ensures that the mass shape, mass speed, sorting area, blowing parameters are matched with each other.

Optionally, the conveying device is a conveyor belt, and the single-layer uniform mode is adopted to convey the objects to be sorted.

In an alternative embodiment, the method further includes, before the conveying device sends the target to be sorted to the blowing position with the predetermined conveying speed in response to a conveying instruction of the controller: the controller controls the conveying equipment to convey the first type object blocks at the preset conveying speed, wherein the first type object blocks are multi-type object blocks included in a first type object, and under the condition of respectively receiving preset first blowing force, the object blocks with the horizontal distance closest to each other travel, and the object to be sorted includes the first type object; the controller controls the first blowing mechanism to blow the first object block by using the first blowing parameter when the first object block reaches the blowing position; the first dividing plate is arranged at a position determined based on a first drop point of the first type object block after being blown.

It will be appreciated that the manner in which the first divider plate is arranged is not subjectively arranged and is determined based on the first drop point. The controller controls the conveying equipment to adopt a preset conveying speed to convey the first type object block, so that the initial speed of the first type object block, which is separated from the conveying equipment, is the preset conveying speed, and when the first type object block reaches the blowing position, the controller controls the first blowing mechanism to blow the first type object block by adopting a preset first blowing parameter. The position of the first dividing plate is determined based on a first drop point of the first type object block after being blown. Through the processing, the first blowing parameters, the preset transmission speed and the first drop points are mutually related, so that the position setting of the first dividing plate can effectively reduce the occurrence of mispairing.

It should be noted that, the first type object block is preferably set as a predetermined cube object block in the first type object, and is considered as an ideal object block which is most difficult to be blown, and when the object to be sorted is gangue, the cube object block can be difficult to generate under natural conditions, regardless of the coal block or the stone block, therefore, the first falling point is determined by adopting the first type object block, and the object block is weaker in capability of being driven by blowing force than the object blocks naturally generated in the first type object, namely, is closer to the travelling horizontal distance than other object blocks. In order to further avoid that the first partition plate is arranged according to the first falling point to cause interception of the first type object blocks in the first type object, a certain distance can be adjusted to a direction close to the blowing position according to an empirical value, the adjusted distance value is not particularly limited, and the problem that the separation degree of different types of objects is insufficient under the critical state is solved.

Alternatively, the first blowing parameter may be set to include a first pressure parameter and a first solenoid valve flow parameter, where the first pressure parameter is a predetermined maximum value that can be output by the first air supply pipe.

In an alternative embodiment, the method further includes, before the conveying device sends the target to be sorted to the blowing position with the predetermined conveying speed in response to a conveying instruction of the controller: the controller controls the conveying equipment to convey a third type object block by adopting the preset conveying speed, wherein the third type object block is a multi-type object block included in a second type object, and the object block with the farthest horizontal travelling distance is subjected to preset second blowing force respectively, and the object to be sorted includes the second type object; and the controller controls the second blowing mechanism to blow the third block when the third block reaches the blowing position, and determines the second blowing parameter so that the stroke of the second block after being blown does not exceed the first dividing plate.

It can be understood that the second dividing plate is arranged in association with the first dividing plate, so that the mismatch of the corresponding targets to be sorted between the second dividing plate and the first dividing plate can be effectively avoided. The controller controls the conveying equipment to adopt a preset conveying speed to convey the third type object block, so that the third type object block has an initial speed which is the preset conveying speed, and when the third type object block reaches a blowing position, the second blowing mechanism is controlled to blow the third type object block, so that the stroke of the third type object block does not exceed the first dividing plate after the obtained second blowing parameter blows the third type object block. It should be noted that the third type object block may be regarded as being strong in driving capability of the blowing force in the second type object, and may have a further horizontal travel distance than other object blocks in the second type object when the same blowing force is applied. Therefore, the third type object is more easily mismatched into a first area formed by the first partition plate and the distal end boundary of the predetermined area, and the blowing parameters of the second blowing mechanism are adjusted so that the third type object cannot cross the first partition plate, and the second blowing parameters are determined. By the aid of the second blowing parameters obtained through processing, the fact that third-type object blocks which are most easily blown in the second-type objects are mismatched to the first area far away from the blowing position can be effectively avoided, and sorting efficiency is improved.

In an alternative embodiment, after the determining the second blowing parameter, the method further includes: the controller controls the conveying equipment to convey a second type object block by adopting the preset conveying speed, wherein the second type object block is a multi-type object block included in the second type object, and the object block with the closest horizontal distance is traveled under the condition of respectively receiving the preset second blowing force; the controller controls the second blowing mechanism to blow the second-type object block by using the second blowing parameter when the third-type object block reaches the blowing position; the second dividing plate is arranged at a position determined based on a second drop point of the second type object block after being blown.

It will be appreciated that the controller controls the conveying device to convey the second-type object block at the predetermined conveying speed, so that the second-type object block has an initial speed which is the predetermined conveying speed, and when the second-type object block reaches the blowing position, the controller controls the second blowing mechanism to blow the second-type object block at the second dropping point by using the second blowing parameter, the second-type object block drops at the second dropping point after being blown, and the position of the second dividing plate is determined based on the second dropping point. Through the processing, after the second blowing parameters related to the first partition board setting are determined, the third type object blocks which are driven by the blowing force and are strong in the second type object are not mismatched to the first area at the far end, and the second type object blocks which are driven by the blowing force and are weak in the second type object are not mismatched to the third area at the near end, so that the accuracy of the second partition board setting is improved, and the probability of mismatch is further avoided.

It should be noted that, similar to the arrangement of the first type object blocks, the second type object blocks are preferably arranged as predetermined square object blocks in the second type object, and the ideal type object blocks which are considered to be the most difficult to be blown are closer to the traveling horizontal distance than other object blocks in the naturally formed second type object. In order to further avoid that the second dividing plate is arranged according to the second falling point to cause interception of the second type object blocks in the second type object, a certain distance can be adjusted to a direction close to the blowing position according to an empirical value, and the adjusted distance value is not particularly limited.

Step S204, the detection equipment detects the targets to be sorted, obtains the detection result, and sends the detection result to the controller;

it can be understood that the detection device detects the objects to be sorted on the conveying device, and obtains a detection result and sends the detection result to the controller.

Alternatively, the detection device may be an X-ray detector, a color sorter, a laser scanner, or the like. The X-ray detector is used for detecting density and component differences in the objects to be sorted by carrying out X-ray scanning on the objects to be sorted, so as to judge whether the objects to be sorted contain non-combustion substances such as ores, stones and the like. The color selector is used for identifying and sorting the colors and the shapes of the targets to be sorted by utilizing photoelectric sensors and computer vision technology and separating coal gangue with specific colors or shapes. And the laser scanner is used for scanning the target to be sorted through the laser beam, measuring the geometric shape and the size of the target, and sorting the target according to preset parameters. The camera and the image processing system are used for shooting targets to be sorted in real time by the camera, analyzing and processing images by the image processing system, and identifying impurities such as stones, mud blocks and the like. These detection devices may be used alone or in combination to improve the sorting efficiency and accuracy of the targets to be sorted.

Step S206, the controller receives the detection result and determines the injection control strategy based on the target information indicated by the detection result;

it can be understood that the controller receives the detection result, the detection result may indicate the target information of the target to be sorted, and after determining the target information of the target to be sorted, the controller may correspondingly determine the blowing control policy.

Optionally, the target information at least includes a target category, a size and a position of the target to be sorted.

In step S208, the first blowing mechanism and the second blowing mechanism respond to the blowing instruction of the controller, and perform blowing processing indicated by the blowing control policy on the target to be sorted, so that the target to be sorted is sorted into a corresponding region of the plurality of sorting regions.

It can be understood that the first blowing mechanism and the second blowing mechanism are controlled by the controller, respond to the blowing instruction of the controller, and perform blowing processing indicated by the blowing strategy on the targets to be sorted, so as to sort the targets to be sorted into corresponding areas.

In an alternative embodiment, the targets to be sorted include a first type of target, a second type of target, and a third type of target, and determining, based on target information of the targets to be sorted indicated by the detection result, a blowing control strategy for controlling the first blowing mechanism and the second blowing mechanism includes: when the detection result indicates that the target information includes the target to be sorted as the first type of target, the controller determines that the injection control strategy is to control the first injection mechanism to adopt the first injection parameter, and control the second injection mechanism to adopt the second injection parameter to inject the target to be sorted, and inject the target to be sorted reaching the injection position, so that the target to be sorted is sorted to a first area; when the detection result indicates that the target information includes the target to be sorted is the second type of target, the controller determines that the injection control strategy is to control the second injection mechanism to inject the target to be sorted by adopting the second injection parameter, so that the target to be sorted is sorted to a second area; and when the detection result indicates that the target information comprises the target to be sorted as the third type of target, the controller determines that the injection control strategy is to control the first injection mechanism and the second injection mechanism not to perform injection, so that the target to be sorted is sorted to a third area.

It can be understood that the targets to be sorted can comprise a plurality of targets such as a first type target, a second type target, a third type target and the like, and the controller determines which type of target to be sorted is according to the indication of the detection result sent by the detection equipment. In the case that the target information is a first type of target, the target to be sorted is regarded as a first region (i.e., a distal region) formed by the first dividing plate and a predetermined region distal boundary. In order to maintain the separation degree between the first type of targets and the second type of targets, the controller controls the first spraying mechanism to adopt first spraying parameters, controls the second spraying mechanism to spray the targets to be sorted by adopting second spraying parameters, and simultaneously controls the first spraying mechanism and the second spraying mechanism to spray, so that the first type of objects which are most difficult to blow in the first type of targets can obtain enough spraying force and further pass through the first dividing plate. And under the condition that the target information indicates that the target to be sorted is a second type target, controlling a second blowing mechanism by using a blowing control strategy, and blowing the target to be sorted by using the second blowing parameters so as to sort the target to be sorted to a second area. And when the target information is that the target to be sorted is the third type of target, the blowing control strategy is to control the first blowing mechanism and the second blowing mechanism not to blow, in other words, the target to be sorted is sorted to a third area by using a free falling mode. Through the processing, the injection control strategy can be performed corresponding to the target information, and the adopted first injection parameter and second injection parameter are correspondingly associated with the preset transmission speed and the setting of the dividing plate, so that the injection processing is favorably performed, and the efficient sorting capability is realized.

In an alternative embodiment, the first blowing mechanism includes a plurality of first nozzles, the second blowing mechanism includes a plurality of second nozzles, the plurality of first nozzles are arranged in a single row, and the plurality of second nozzles are arranged in a single row, the plurality of first nozzles and the plurality of second nozzles are arranged in a side-by-side arrangement in the blowing position; when the detection result indicates that the target information includes the target to be sorted as the first type of target, the controller determines that the injection control strategy is to control the first injection mechanism to use the first injection parameter, and to control the second injection mechanism to use the second injection parameter to inject the target to be sorted, and to inject the target to be sorted reaching the injection position, the method includes: the controller determining a first opening range of the first nozzles and a second opening range of the second nozzles based on the detection result indicating that the target information includes the position and the size of the target to be sorted; the controller determines that the injection control strategy is a first nozzle which is arranged in the first opening range, the first injection parameters are respectively adopted, and a second nozzle which is arranged in the second opening range is respectively adopted to inject the targets to be sorted which reach the injection position by adopting the second injection parameters; when the detection result indicates that the target information includes the target to be sorted is the second type of target, the controller determines that the injection control strategy is to control the second injection mechanism to inject the target to be sorted by using the second injection parameter, including: the controller determines a third opening range in the plurality of second nozzles based on the detection result indicating that the target information includes the position and the size of the target to be sorted; the controller determines the blowing control strategy to control the second nozzles arranged in the third opening range, and uses the second blowing parameters to blow the targets to be sorted reaching the blowing position.

It will be appreciated that for a wide conveyor, it will be readily appreciated that the blowing location will be provided at the end of the conveyor, and therefore the first nozzle, the second nozzle are also provided in plurality side-by-side arrangement in the above-described blowing location. According to the target information obtained by the detection result, besides the type of the target to be sorted, the position and the size of the target to be sorted can be indicated, and under the condition that the target information is the first type of target, the controller determines the first opening ranges of the first nozzles and the second opening ranges of the second nozzles, and correspondingly, the injection control strategy is to control the first nozzles arranged in the first opening ranges, respectively adopt the first injection parameters, and control the second nozzles arranged in the second opening ranges, respectively adopt the second injection parameters to carry out injection on the target to be sorted reaching the injection position. Similarly, under the condition that the target information is the second type of targets, the controller determines a third opening range of the plurality of second nozzles, and the injection control strategy is to control the second nozzles arranged in the third opening range to inject the targets to be sorted reaching the injection position. The third opening range and the second opening range may be overlapped or not overlapped, and it should be noted that, under the condition of simultaneously transmitting a plurality of objects to be sorted, the objects to be sorted are distributed on the conveying device in a single layer, so that the problem that the third opening range and the second opening range overlap with each other does not exist for the plurality of objects to be sorted. Through the treatment, the spraying treatment can be finished by only opening a partial first nozzle in the first spraying mechanism and a partial second nozzle in the second spraying mechanism.

Optionally, fig. 3 is a schematic top view of an alternative multi-target sorting control method according to an embodiment of the present invention, where a large circle in fig. 3 represents a first nozzle included in a first blowing mechanism, a small circle represents a second nozzle included in a second blowing mechanism, and a solid black circle represents a nozzle selected to be opened. The timing of the controller controlling the blowing is known, because the conveying device is conveyed at a predetermined conveying speed, the position of the detection area is also fixed, and the timing of the target to be sorted reaching the blowing position can be determined, so that the timing of the blowing is obtained. And the blowing treatment of a plurality of different kinds of targets can be simultaneously executed, and for the first kind of targets (marked as black circles), the treatment can be determined by adopting the nozzles with the first opening range in the first blowing mechanism and the nozzles with the second opening range in the second blowing mechanism. When the second type of targets (marked as black hexagons) pass through the detection area, the controller can determine the position and the size of the second type of targets through the detection result, and when the second type of targets reach the spraying position, the controller determines that the spraying is performed by adopting the nozzles with the third opening range in the plurality of second nozzles. It should be noted that, the objects to be sorted are distributed on the conveying device in a single-layer conveying manner, often appear in a plurality of different objects in an application scene, reach the blowing position at the same moment, and can effectively execute corresponding blowing treatment on the plurality of different objects in a manner of determining the blowing opening range.

Through the steps S202 to S208, the purpose that the setting of the blowing parameters is matched with the granularity of the target to be sorted can be achieved, the technical effect of improving the target sorting accuracy is achieved, and the technical problem that the target sorting accuracy is not ideal in the related technology is solved.

Based on the above embodiment and the optional embodiment, the present invention proposes an optional implementation, specifically the following steps: fig. 4 is a schematic application diagram of a multi-target sorting control system according to an embodiment of the present invention, which is applied to a three-target sorting system, including a conveying device 102 and a detecting device 104, where the blowing device includes a first blowing mechanism 106 and a second blowing mechanism 108, the first blowing mechanism 106 is provided with a plurality of first nozzles (i.e. large nozzles), the second blowing mechanism 108 is provided with a plurality of second nozzles (i.e. small nozzles), the controller 114, the first dividing plate 110, the second dividing plate 112, the regional near-end boundary 402, the regional far-end boundary 404, the first dividing plate 110 and the regional far-end boundary 404 are divided to obtain a first region 406, the first dividing plate 110 and the second dividing plate 112 are divided to obtain a second region 408, the second dividing plate 112 and the regional near-end boundary 402 are divided to obtain a third region 410, and the system is used for sorting targets 412. The above-mentioned conveying device is a conveyor belt, and in fig. 4, a plurality of small nozzles arranged side by side are shown as one (a plurality of large nozzles are the same), and the lower nozzle design is adopted, and two rows of nozzles arranged side by side are arranged at the spraying position.

The targets to be sorted may be in various particle size ranges, for example 300mm-50mm (millimeters), 100mm-25mm, 50mm-10 mm. The belt speed of the conveyor belt is controlled between 1.5m/s (meters per second) and 3.0m/s, and can be determined according to specific requirements.

According to past experience, in order to blow targets to be sorted, for a granularity range of 300mm-50mm, a large nozzle and a first electromagnetic valve flow parameter Cv value 3.5-5 (dimensionless) matched with the large nozzle and a second electromagnetic valve flow parameter 1-2 matched with the small nozzle can be selected; for the granularity range of 100mm-25mm, the large nozzle and the first electromagnetic valve flow parameter Cv value 1-2 matched with the large nozzle and the small nozzle and the second electromagnetic valve flow parameter 0.4-0.7 matched with the small nozzle can be selected; for the granularity range of 50mm-10mm, the large nozzle and the matched first electromagnetic valve flow parameter Cv value of 0.4-0.7, and the small nozzle and the matched second electromagnetic valve flow parameter of 0.1-0.2 can be selected.

The first blowing mechanism adopts a first air supply pipe, the second blowing mechanism adopts a second air supply pipe to supply air independently, pressure reducing valves are arranged on the respective pipelines and correspond to the first pressure parameter and the second pressure parameter respectively, in general, the first air supply pressure which can be supported by the first air supply pipe ranges from 0.8MPa to 1.0MPa, and the second air supply pressure which can be supported by the second air supply pipe ranges from 0.5MPa to 0.8 MPa.

For a three-target sorting system, the granularity range of the targets to be sorted is determined, and the targets to be sorted can be the first type of targets: middlings, second kind target: gangue, third class target: the content of the coal in the clean coal is higher than that in the middling coal, and the density of the clean coal is smaller than that of the middling coal. Assuming that the object to be sorted is in the particle size range of 300mm-50mm, the first blowing parameters of the first blowing mechanism and the second blowing parameters of the second blowing parameters can be determined correspondingly, and the predetermined transport speed of the conveying device, which is fixed when the sorting area is determined, and the adjustment of the position of the dividing plate is changed once the transport speed is changed.

The first area formed between the first dividing plate and the distal boundary of the area is used for sorting the first type of targets, in order to determine the position of the first dividing plate, a typical multi-type object block in the first type of targets is selected, and cube objects (namely the first type object block) which are least prone to being blown are determined according to the distance of the horizontal distance traveled by the same blowing force. Firstly, conveying the first type object blocks in the first type object at a preset conveying speed by adopting conveying equipment, so that the initial speed of the first type object blocks in the first type object is the preset conveying speed, controlling a first blowing mechanism to blow the first type object blocks, opening the output of a large nozzle in the first blowing mechanism to the maximum, supposing 0.8MPa (namely, a first pressure parameter in first blowing parameters), recording a falling point (namely, a first falling point) of the first type object blocks in the first type object, obtaining the position of a first dividing plate based on the falling point, and performing position fine adjustment appropriately to increase the separation degree of the target type.

After the first dividing plate is determined, the position of a second dividing plate needs to be determined, and the second dividing plate is close to the blowing position compared with the first dividing plate and forms a second area for sorting the second type of targets together with the first dividing plate. Therefore, the adjustment process is required according to the shape characteristics of the object blocks of the second class, so as to determine the flat object block (i.e. the third type object block) which is most easily blown in the second class and the cube object block (i.e. the second type object block) which is most difficult to blow. And controlling the second blowing mechanism to blow the third type object block (with the initial speed being the preset transmission speed) in the second type object, so that the third type object block cannot be blown to exceed the first dividing plate, and obtaining the second blowing parameter of the second blowing mechanism, and avoiding being mismatched to the first area far away from the blowing position.

And (3) adopting the obtained second blowing parameters to blow the second type object block (with the initial speed being the preset transmission speed), and obtaining the position of the second dividing plate based on the falling point (namely the second falling point) of the second type object block, so that the position fine adjustment can be properly performed.

Through the processing, the positions of the first dividing plate and the second dividing plate are controlled and adjusted, so that the object block shape, the blowing parameter, the nozzle selection, the sorting area division and the preset conveying speed of the objects to be sorted can be effectively matched with each other. For the actual processing of the targets to be sorted of the three-product sorting system, the targets to be sorted are conveyed in a single-layer mode by adopting conveying equipment at a preset conveying speed, and when the targets pass through a detection area of the detection equipment, the controller obtains a detection result of the targets to be sorted. For the first blowing mechanism and the second blowing mechanism, not all the nozzles are opened every time, and the controller determines partial nozzles corresponding to the opening of the targets to be sorted based on the target information indicated by the detection result. Similarly, the local opening control can be performed on the large nozzle and the small nozzle, so that the sorting processes of different targets at the injection position are simultaneously achieved without mutual interference, and the effect of simultaneous sorting can be realized.

At least the following effects are achieved by the above alternative embodiments: the electromagnetic valve is designed and controlled based on the factors of electromagnetic valve selection, nozzle design, material size sorting, belt speed, air supply pressure and mutual coupling of cutting of a spraying target area, so that the aim of accurate spraying is fulfilled, especially for a second area in the middle, the setting precision of spraying force of the nozzle is improved, and the mismatch rate of the sorting target in the second area can be greatly reduced.
