Description
Technical Field
[0001] This invention relates to the field of sorting device technology, and in particular to an intelligent vision sorting device for solid waste treatment. Background Technology
[0002] Solid waste encompasses various types, including industrial solid waste and hazardous waste. Its composition is complex and often contains valuable substances, harmful impurities, and ordinary materials. Efficient sorting is a key link in resource recycling and harmless disposal. Currently, solid waste sorting mainly relies on manual sorting and traditional mechanical sorting technology, which has many prominent problems.
[0003] Manual sorting is labor-intensive and inefficient, making it unsuitable for large-scale processing needs. Furthermore, operators directly handle hazardous waste, posing significant health risks. Sorting accuracy is also susceptible to human error. Traditional mechanical sorting devices lack effective material distribution structures, leading to material clumping and obstructing the subsequent inspection field of view, significantly reducing identification accuracy. Simultaneously, their detection methods are limited, relying primarily on visual identification, which cannot accurately determine the composition of waste, especially the content of harmful elements such as heavy metals, easily resulting in the omission of hazardous waste or the waste of valuable materials. Therefore, those skilled in the art have provided an intelligent visual sorting device for solid waste treatment to address the problems mentioned in the background. Summary of the Invention

[0005] Furthermore, a telescopic pipe is connected between the feeding hopper and the loading bin, an inclined partition is provided on the inner wall of the material conveying box, a material equalization chamber is provided on one side of the partition, a feeding port communicating with the telescopic pipe is provided at the upper end of the transfer bin, and a discharge port communicating with the material conveying box is provided at the lower end of the transfer bin. Specifically, the partition restricts the solid waste falling into the transfer chamber. The solid waste conveyed by the hopper enters the transfer chamber through the feed port and is discharged through the discharge port during the rotation inside the transfer chamber.
[0006] Furthermore, the material feeding box is provided with limiting plates at the upper edge of the conveyor belt at both the front and rear ends, and symmetrically distributed conveyor rollers are rotatably installed inside the frame. The upper support rollers that fit against the inner wall of the upper end of the conveyor belt are also rotatably installed inside the frame. Specifically, the limiting plates at the edges of the conveyor belt prevent solid waste from falling into the outside world, and the upper idler rollers enhance the support strength of the conveyor belt as it travels.
[0007] Furthermore, the intelligent vision sorting mechanism is fitted with a baffle box on the outside of the conveying structure, and material distribution conveyors are provided on both the front and rear sides of the frame; Specifically, the external environment is reduced to reduce light interference during the visual sorting process by using baffles, and the material conveyor is used to transfer and transport materials during the clamping and sorting process.
[0008] Furthermore, the intelligent vision sorting mechanism includes an industrial CCD camera, a laser contour sensor, an X-ray fluorescence spectrometer, and a supplementary light source. The industrial CCD camera and the laser contour sensor work together to collect the shape, size, color, and surface texture features of the waste. The X-ray fluorescence spectrometer is used to quickly detect the content of heavy metal elements in the waste. The supplementary light source is a ring-shaped high-brightness LED light source, and its light intensity can be automatically adjusted according to the color of the waste to ensure recognition accuracy. Specifically, the industrial CCD camera and laser contour sensor work together to collect the shape, size, color and surface texture features of the waste. The X-ray fluorescence spectrometer can quickly detect the content of heavy metal elements in the waste. The supplementary light source adopts a ring-shaped high-brightness LED light source, and its light intensity can be automatically adjusted according to the color of the waste to ensure recognition accuracy.
[0009] Furthermore, a torsion spring is sleeved on the outer side of the rotating shaft, with its two ends respectively connected to the rotating arm and the bracket, and a limiting rod is provided on the inner wall of the material distribution box to fit against one side of the lower end of the rotating arm; Specifically, the pivot provides rotational support to one end of the rotating arm, and a torsion spring provides torsional elastic support. A limit rod prevents the rotating arm from falling downwards from its lower position.
[0010] Furthermore, the sorting structure includes an electromagnetic guide rail fixed above the conveyor belt, reciprocating and equidistantly arranged, an electromagnetic slider electromagnetically slidably mounted on the outer wall of the electromagnetic guide rail, a telescopic rod located at the lower end of the electromagnetic slider, a gripper located at the lower end of the telescopic rod, a positive pressure air source below the frame, a connecting box located at the output end of the positive pressure air source, a blowpipe connected to the connecting box and equidistantly distributed, and a nozzle located at one end of the blowpipe and below the end of the conveyor belt. Specifically, the electromagnetic slider slides on the outer wall of the electromagnetic guide rail, driving the gripper to the designated position. The gripper is driven to descend and clamp the sorted solid waste through the telescopic rod. The positive pressure air source delivers high-pressure airflow, which is sprayed out in a bundle shape through the blow pipe and nozzle to achieve the sorting of different types of solid waste.
[0011] 2. Beneficial effects Compared with the prior art, the advantages of this invention are: In this invention, firstly, solid waste enters the transfer bin through the feeding hopper, is initially dispersed by the sorting plate, and then falls into the feeding box. Subsequently, the impact roller and the dispersing block break up large pieces of waste, and the pusher further separates the stacked materials, so that the waste is evenly distributed on the conveyor belt. Then, the conveyor belt transports the single-layer discrete waste to the detection area of the intelligent vision sorting mechanism. An industrial CCD camera, a laser contour sensor, and an X-ray fluorescence spectrometer detector work together to collect data on shape, color, texture, and heavy metal content. The supplementary light source automatically adjusts the illumination to ensure recognition accuracy. Finally, based on the detection results, the sorting structure sorts the waste to the corresponding sorting conveyor by using an electromagnetic guide rail to drive the gripper or a positive pressure air source to drive the nozzle. The uniform material structure achieves homogenization of solid waste treatment, effectively avoiding material stacking and significantly improving waste dispersion. The material distribution plate in the transfer bin works in conjunction with the impact rollers, dispersion blocks, and push blocks in the feeding box. Simultaneously, when passing through the channel below the partition, the push blocks with torsional elastic support automatically hook onto any stacked materials, separating any remaining stacked solids. The push blocks automatically reset via torsional elastic components, ensuring continuous separation and use. This process disperses large or clump-like waste materials and distributes them evenly on the conveyor belt, ensuring that the waste passes through the detection area of the intelligent vision sorting mechanism in a single layer and discrete state. This highly dispersed material state greatly reduces mutual occlusion between materials, providing a clear and complete recognition field for visual inspection equipment such as industrial CCD cameras and laser contour sensors. This improves the recognition accuracy of shape, size, color, and surface texture features, laying a solid foundation for subsequent precise sorting.
[0012] Of course, any product implementing this invention does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

A telescopic pipe 112 connects the feeding hopper 113 and the loading bin. An inclined partition 103 is provided on the inner wall of the material conveying box 101. A material equalization chamber 104 is provided on one side of the partition 103. A feeding port 110 connected to the telescopic pipe 112 is provided at the upper end of the transfer bin 107. A discharge port 111 connected to the material conveying box 101 is provided at the lower end of the transfer bin 107. The front and rear ends of the feeding box 101 are equipped with limiting plates 102 located at the upper edge of the conveyor belt 203. The intelligent vision sorting mechanism 300 and the outer side of the conveying structure 200 are fitted with baffle boxes 122. The front and rear sides of the frame 201 are equipped with material distribution conveyors 205. A torsion spring 118 is sleeved on the outside of the rotating shaft 108, with its two ends connected to the rotating arm 121 and the bracket 116 respectively. A limiting rod 120 is provided on the inner wall of the material distribution box, which fits against one side of the lower end of the rotating arm 121. as well as; Intelligent vision sorting mechanism 300 is fixed above and to one side of the frame 201; The intelligent vision sorting mechanism 300 includes an industrial CCD camera, a laser contour sensor, an X-ray fluorescence spectrometer, and a supplementary light source. The industrial CCD camera and the laser contour sensor work together to collect the shape, size, color, and surface texture features of the waste. The X-ray fluorescence spectrometer is used to quickly detect the content of heavy metal elements in the waste. The supplementary light source is a ring-shaped high-brightness LED light source, and its light intensity can be automatically adjusted according to the color of the waste to ensure recognition accuracy. Sorting structure 400 is fixed between frame 201 and intelligent vision sorting mechanism 300; The sorting structure 400 includes an electromagnetic guide rail 401 fixed above the conveyor belt 203 and arranged in a reciprocating pattern at equal intervals; an electromagnetic slider 402 electromagnetically slidably mounted on the outer wall of the electromagnetic guide rail 401; a telescopic rod 403 located at the lower end of the electromagnetic slider 402; a gripper 404 located at the lower end of the telescopic rod 403; a positive pressure air source 405 located below the frame 201; a connecting box 406 located at the output end of the positive pressure air source 405; a blowpipe 407 connected to the connecting box 406 and arranged at equal intervals; and a nozzle 408 located at one end of the blowpipe 407 and below the end of the conveyor belt 203. It is used when performing material equalization structure 100, conveying structure 200, intelligent vision sorting mechanism 300 and sorting structure 400; Solid waste enters the transfer chamber 107 through the feed hopper 113. Motor 2 115 drives the rotating shaft 108 to rotate the distribution plate 109. The distribution plate 109 initially breaks up the batch of feed material to prevent clumping and blockage. The broken-up waste falls into the feeding box 101 through the discharge port 111. The partition 103 inside the feeding box 101 guides the waste flow to the equalization chamber 104. Simultaneously, motor 114 drives the impact roller 105 to rotate. The dispersing blocks 106 on the outer wall of the impact roller 105 further impact and break up large or adhered pieces of waste. During this process, the safety device on the support 116 on the inner wall of the feeding box 101... The mounting shaft 117 drives the rotating arm 121 and the lever 119 to move. The torsion spring 118 provides elastic support for the lever 119. When the stacked waste passes by, the lever 119 automatically hooks and separates the stacked material. The limit rod 120 restricts the excessive swing of the rotating arm 121, ensuring that the lever 119 can be reset by the torsion spring 118 after separating the material and continue to play a dispersing role. Finally, under the synergistic action of the impact roller 105, the dispersing block 106 and the lever 119, the waste falls onto the conveyor belt 203 in a single layer and discrete state. The limit plate 102 at the edge of the conveyor belt 203 prevents the waste from falling. The conveyor belt 203 runs smoothly under the drive of the conveyor roller 202. The upper idler roller 204 provides support for the conveyor belt 203 to avoid deformation of the conveyor belt 203 due to the weight of the material, which would affect the conveying stability. When the discrete waste material is conveyed to the detection area of the intelligent vision sorting mechanism 300, the baffle box 122 isolates the external light interference to ensure a stable detection environment. The industrial CCD camera and the laser contour sensor work together to collect the shape, size, color and surface texture features of the waste material. The X-ray fluorescence spectrometer detector quickly detects the heavy metal elements in the waste material and identifies harmful components. The ring high-brightness LED supplementary light source automatically adjusts the light intensity according to the color of the waste material to avoid the surface reflection of the waste material or insufficient light affecting the recognition accuracy. All kinds of detection data are transmitted to the background processing system for analysis in real time. After processing the detection data, the background system sends targeted sorting instructions to the sorting structure 400. If the waste is identified as large pieces of valuable waste, the electromagnetic guide rail 401 drives the electromagnetic slider 402 to move to the designated position. The telescopic rod 403 extends and drives the gripper 404 to close. After accurately grabbing the waste, the electromagnetic slider 402 moves to the top of the corresponding material conveyor 205. The gripper 404 opens to release the waste, completing the grabbing and sorting. If the waste is identified as fine granular waste or lightweight waste, the positive pressure air source 405 is activated. The high-pressure airflow is distributed to the corresponding blowpipe 407 through the connecting box 406, and then sprayed in a bundle shape through the nozzle 408 to blow the waste to the designated material conveyor 205. For different types of mixed waste, the system can simultaneously control the gripper 404 to grab and the nozzle 408 to spray, realizing multi-mode collaborative sorting and ensuring accurate separation of various types of waste. After sorting, the waste material is transferred to the corresponding collection area by the sorting conveyor 205 to complete the classification and collection. After a single sorting is completed, the electromagnetic slider 402, telescopic rod 403, and gripper 404 are reset, the positive pressure air source 405 stops supplying air, the nozzle 408 is closed, and the conveyor belt 203 continues to transport subsequent materials to enter the next sorting cycle. When feeding stops, the device continues to run until all the waste material on the conveyor belt 203 is sorted, each component is reset in sequence, the sensor performs a self-check again, and then enters the standby state. Solid waste to be processed is concentrated and fed into the feed hopper 113. The telescopic pipe 112 between the feed hopper 113 and the transfer bin 107 can adapt to different feed volumes and avoid congestion caused by excessive feeding. Before entering the transfer bin 107, the waste does not require additional manual pretreatment. It is directly dispersed and broken up by the device's own material equalization structure 100, simplifying the initial operation process. The material distribution plate 109 in the transfer bin 107 rotates to initially disperse the batch of feed, breaking up the agglomeration of the material and laying the foundation for subsequent dispersion. The impact roller 105 and the dispersing block 106 rotate at high speed to impact large or sticky pieces of waste, breaking them down into small pieces of material with uniform particle size. The pusher block 119 separates the remaining stacked material through elastic movement, ensuring that the material is distributed in a single layer on the conveyor belt 203 without mutual obstruction, providing a clear field of vision for visual inspection. The conveyor belt 203 adopts a stable conveying mode. The upper idler roller 204 enhances the support strength of the conveyor belt 203 and prevents the material from shaking or shifting during the conveying process. The conveying speed, material feeding speed, and sorting speed are adaptively matched to ensure that materials have sufficient dwell time in the detection area, allowing the vision sensor to collect complete data. This also prevents sorting delays caused by excessively fast conveying. An industrial CCD camera captures the color and surface texture of the waste, while a laser contour sensor acquires its three-dimensional dimensions. Together, they achieve comprehensive identification of the waste's physical characteristics. An X-ray fluorescence spectrometer rapidly detects heavy metals and other harmful components in the waste, determining its environmental attributes. The supplementary lighting source dynamically adjusts according to ambient light and waste color to ensure the accuracy and consistency of the detection data. The baffle 122 isolates external interference, ensuring a stable detection environment. For large, valuable waste materials, such as precious metal components and high-purity plastic blocks, electromagnetic rails 401 are used for precise positioning, along with telescopic rods 4. 03 Adjust the height of the gripper 404. After the gripper 404 closes and grabs, the material is transferred to the corresponding collection channel to ensure a smooth and damage-free grabbing process. For fine particles or lightweight waste, the positive pressure air source 405 provides high-pressure airflow, which is sprayed directionally through the nozzle 408. The impact force of the airflow is used to separate the waste to the designated area to avoid secondary pollution of the waste. For mixed waste, fine particles are first separated by spray sorting, and then large pieces are recovered by grabbing sorting, so as to realize the simultaneous separation of multiple types of waste and improve sorting efficiency. After sorting, the waste is transferred to the valuable material collection area, hazardous waste collection area and general waste collection area by the material conveyor 205 to realize classified storage and subsequent processing. The separate collection of hazardous waste can avoid secondary pollution, and the centralized recycling of valuable materials can improve resource utilization. The frame 201 is welded from steel to ensure overall stability. The conveyor belt 203 is made of wear-resistant and corrosion-resistant rubber with an anti-slip texture. The conveyor rollers 202 and upper support rollers 204 are made of stainless steel to reduce wear. The limit plate 102 is made of elastic rubber to prevent damage and dust from impacts with waste materials. The feed box 101 and transfer bin 107 are injection molded from PP engineering plastic, which is lightweight and corrosion-resistant. The impact roller 105 and dispersing block 106 are made of high-strength alloy steel to enhance wear resistance. The distribution plate 109, rotating arm 121, and lever 119 adopt a composite structure of elastic rubber and metal skeleton to ensure dispersion effect while avoiding damage to waste materials. The torsion spring 118 is made of stainless steel to ensure elastic stability and service life. The industrial CCD camera is an industrial-grade high-definition camera. The laser contour sensor has anti-interference capabilities. The X-ray fluorescence spectrometer meets national safety standards. The supplementary lighting source is a dimmable ring LED light group. The baffle box 122 uses a combination of a light shield and a sealing strip. The structure ensures a closed and stable testing environment. The electromagnetic guide rail 401 and electromagnetic slider 402 utilize high-precision linear drive components. The telescopic rod 403 is a pneumatic telescopic rod. The gripper 404 uses a wear-resistant rubber gripping surface to avoid damaging valuable waste materials. The positive pressure air source 405 uses a silent air compressor. The connecting box 406 and blowpipe 407 are made of stainless steel. The nozzle 408 has a detachable structure for easy cleaning and maintenance. The material distribution conveyor 205 is a small belt conveyor, seamlessly connecting with the main conveyor belt 203. During assembly, ensure that all components are securely connected. After installation, adjust the conveyor belt 203 to a horizontal position to avoid deviation. The distance between the impact roller 105 and the pusher block 119 of the material equalization structure 100 needs to be adjusted according to the common waste material size to ensure dispersion effect. The detection components of the intelligent vision sorting mechanism 300 need to be calibrated to the same detection plane to avoid detection deviation. The gripper 404 and nozzle 408 of the sorting structure 400 need to be precisely aligned with the inlet of the material distribution conveyor 205 to ensure that the sorted waste material can fall accurately into the conveying channel. The intelligent vision sorting mechanism 300 combines multi-dimensional detection with the differentiated execution of the sorting structure 400, which can accurately identify and separate different types of waste. The separation of hazardous waste can effectively reduce environmental risks, and the recycling of valuable materials improves resource utilization. The entire process does not require manual intervention in the sorting action. Only operators need to monitor the feeding and equipment operation status, which reduces labor intensity and avoids the health risks of operators coming into contact with hazardous waste.
