Description

Technical Field

[0001] This invention belongs to the field of solid waste separation and recycling technology, and particularly relates to a solid waste sorting and processing device. Background Technology

[0002] Solid waste sorting and treatment is a key step in achieving the reduction, resource recovery, and harmlessness of solid waste. Separating mixed solid waste into different categories lays the foundation for subsequent recycling, sanitary landfill, and other treatment methods, which is beneficial to environmental protection.

[0003] When using a production line to sort solid waste into various recyclable materials, the diverse range of recyclable materials, including but not limited to plastics, metals, and glass, means that the sorted plastics may contain hard materials such as metals and glass. Further processing of the recycled plastics may result in damage to the equipment from these hard materials. Additionally, the sorted plastics and other recyclable materials may be covered with impurities such as soil, fruit pulp, and leaves. These impurities not only lead to impurities in the separated recyclable materials, requiring significant effort to remove them and resulting in low separation efficiency, but also cause dirt buildup on the sorting equipment and may even shorten its lifespan.

[0004] To solve the above problems, a new type of solid waste sorting and processing device is needed. Summary of the Invention

[0005] The purpose of this invention is to provide a solid waste sorting and processing device that can prevent hard materials such as metal and glass from being mixed into the sorted plastics, and can also improve the cleanliness of the sorted plastics and other recyclables, thereby increasing the sorting efficiency.

[0006] To achieve the above objectives, the present invention provides a solid waste sorting and processing device, including a sorting tank. The cavity of the sorting tank is filled with a cleaning liquid with a density less than that of plastic. A sediment conveying assembly is provided at the bottom of the cavity.

An angle is formed between the plastic discharge assembly's conveying direction for plastic and the sediment conveying assembly's conveying direction for sediment.

[0007] Preferably, the bending plate includes a horizontal part and a vertical part. The horizontal part is adapted to the structure of the cleaning chamber. The vertical part is fixedly connected to one end of the bottom surface of the horizontal part near the interceptor plate. The horizontal part has a plurality of vertical through holes. An interceptor mesh plate is detachably connected to the bottom surface of the horizontal part, and the interceptor mesh plate covers all the vertical through holes.

[0008] Preferably, the drive assembly includes a support frame, the top plate of which is provided with guide grooves and a rack arranged in parallel. The rack is located directly above the cleaning chamber and perpendicular to the interceptor plate. A slide block is slidably connected in the guide groove.

The telescopic part of the lifting power device passes through the slide block and is fixedly connected to the bending plate. The output shaft of the travel drive motor is fixedly connected to a travel gear, and the travel gear meshes with the rack.

[0009] Preferably, the sediment conveying assembly includes a first conveyor belt, a connector, and a second conveyor belt arranged along the length of the sorting tank. The first conveyor belt is horizontally arranged, with its two ends respectively fitted onto a first driving roller and a first driven roller. Both the first driving roller and the first driven roller are rotatably connected to the side wall of the sorting tank. The first driving roller is located at one end of the sorting tank and connected to a first motor. The second conveyor belt is inclined, with ribs evenly distributed on its conveying surface. Its two ends are respectively fitted onto a second driven roller and a second driving roller. The second driven roller is rotatably connected to the side wall of the sorting tank and located below the first driven roller. The second driving roller is rotatably connected to a fixed frame on the top surface of the sorting tank and connected to a second motor. The connector is used to connect the first conveyor belt and the second conveyor belt.

[0010] Preferably, the connecting member includes a fixed plate, which is fixedly connected to the bottom of the sorting tank and located below the first conveyor belt. A plurality of guide rods are fixedly connected to one side of the fixed plate, and springs are sleeved on the guide rods. One end of the spring is fixedly connected to the fixed plate, and the other end of the spring is fixedly connected to a movable plate. A guide hole corresponding to each guide rod is opened on one side of the movable plate. The top surface of the movable plate contacts the bottom surface of the first conveyor belt, and the side of the movable plate away from the fixed plate contacts the end of the second conveyor belt.

[0011] Preferably, the plastic discharge assembly includes a support plate fixedly connected to the sorting tank, the support plate being parallel to the interceptor plate and the bottom end of the support plate being immersed in the cleaning liquid, and levers evenly distributed along the width direction of the sorting tank being rotatably connected to the support plate, at least one actuating plate being fixedly connected to the levers, and the levers being connected to a rotary drive assembly.

[0012] Preferably, the rotary drive assembly includes a third motor, a drive gear, a driven gear, and several transmission gears. The third motor is located at one end of the support plate. The drive gear is fixedly connected to the output shaft of the third motor. The drive gear meshes with the driven gear. The driven gear is fixedly connected to one end of one of the levers. The transmission gear is fixedly connected to the lever. Two transmission gears on two adjacent levers are connected by a toothed belt drive.

[0013] Preferably, a drying component is provided below the plastic discharge port of the plastic discharge assembly. The drying component includes a water storage tank, a drying chamber, and a conveyor belt. The drying chamber and the conveyor belt are both fixedly connected to the top surface of the water storage tank. A shielding curtain is provided at both the inlet and outlet of the drying chamber. Fans are evenly distributed along the length of one side of the drying chamber, and the fans face the conveyor belt. The other side of the drying chamber is connected to a bag filter through an air outlet. A filter screen is provided at the air outlet. The conveyor belt runs horizontally through the drying chamber.

The third driven roller and the third driving roller are rotatably connected to the top edge of the water storage tank. The third driven roller is located in a groove on the side wall of the sorting tank. The third driving roller is connected to a fourth motor.

[0014] Preferably, the actuating plate on the lever near the drying assembly has a hollow structure.

[0015] Therefore, the solid waste sorting and processing device of the present invention, which adopts the above-described structure, has the following beneficial effects:

[0016] 1. The bending plate is used to repeatedly press the plastic floating on the surface of the cleaning liquid into the cleaning liquid to achieve the cleaning of the plastic. The vertical through holes and intercepting mesh plate on the bending plate can increase the turbulence of the cleaning liquid in the sorting tank, thereby increasing the cleaning power of recyclable materials such as plastic, metal and glass and improving the sorting efficiency.

[0017] 2. The cleaning fluid causes the less dense plastics to float on the surface. Then, the bending plate moves the plastics from the cleaning chamber to the separation chamber. Finally, the plastic discharge component removes the plastics from the sorting tank. The denser metals and glass sink to the bottom of the sorting tank and are then transported out of the sorting tank by the sediment conveying component. This process completely separates the plastics from the hard materials such as metals and glass in the recyclable materials, preventing equipment damage caused by the mixing of hard materials such as metals and glass into the plastics during further processing.

[0018] 3. The use of a drying unit can prevent liquid from the plastic from dripping directly onto the ground, allowing for the recovery of cleaning fluid and keeping the ground clean and tidy.

[0019] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Attached Figure Description

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Example

[0030] Reference Figures 1-6As shown, this embodiment provides a solid waste sorting and processing device, including a sorting tank 1. A water outlet with a sealed cap is provided at the bottom of one side wall of the sorting tank 1 for easy replacement of the cleaning solution. The cavity of the sorting tank 1 is filled with a cleaning solution with a density less than that of plastic. A sediment conveying assembly 2 is provided at the bottom of the cavity, used to remove hard materials such as metal and glass that have sunk to the bottom of the sorting tank 1. An interceptor plate 3, immersed in the cleaning solution, is fixedly connected inside the cavity. The top surface of the interceptor plate 3 has a plastic channel, and the bottom surface of the interceptor plate 3 has a sediment channel. The interceptor plate 3 divides the cavity into a cleaning chamber 4 and a separation chamber 5, preventing plastic from directly entering the separation chamber 5 without repeated settling and cleaning. A bending plate 6 is provided above the cleaning chamber 4, connected to a drive assembly 7 for lifting, lowering, and translating. A plastic discharge assembly 8 is provided above the separation chamber 5, with an angle between the plastic discharge assembly 8's conveying direction and the sediment conveying assembly 2's conveying direction.

[0031] In use, the cleaning fluid can be water or medical alcohol. The conveying direction of the plastic discharge component 8 to the plastic and the conveying direction of the sediment conveying component 2 to the sediment are set perpendicular to each other. Solid waste mixed with plastic and other hard materials (metal and glass) is placed into the cleaning chamber 4. The plastic floats on the surface of the liquid, while the other hard materials (metal and glass) sink to the bottom of the sorting tank 1. Then, the repeated raising and lowering of the bending plate 6 repeatedly presses the plastic floating on the surface of the cleaning fluid into the cleaning fluid, creating turbulence and cleaning the plastic and other hard materials (metal and glass). Subsequently, the translation of the bending plate 6 pushes the plastic from the cleaning chamber 4 to the separation chamber 5, and the plastic discharge component 8 removes the plastic from the sorting tank 1. The sediment conveying component 2 conveys and removes the other hard materials (metal and glass) from the sorting tank 1. This device simultaneously separates and cleans plastic and other hard materials (metal and glass), eliminating the need for cleaning after sorting, thus improving sorting efficiency.

[0032] In a further preferred embodiment, the bending plate 6 includes a horizontal portion 61 and a vertical portion 62. The horizontal portion 61 is adapted to the structure of the cleaning chamber 4. The vertical portion 62 is fixedly connected to the bottom surface of the horizontal portion 61 near one end of the interceptor plate 3. The horizontal portion 61 has several vertical through holes 10. An interceptor mesh plate 9 is detachably connected to the bottom surface of the horizontal portion 61, and the interceptor mesh plate 9 covers all the vertical through holes 10.

[0033] In use, the distance between the top of the interceptor plate 3 and the surface of the cleaning fluid is less than the length of the vertical surface of the vertical part 62 of the bending plate, and the distance between the bottom of the interceptor plate 3 and the sediment conveying assembly 2 is greater than the length of the vertical surface of the vertical part 62 of the bending plate. When the plastic floating on the surface of the cleaning fluid is repeatedly pressed into the cleaning fluid by the repeated lifting and lowering of the bending plate 6, the drive assembly 7 moves the bottom of the vertical part 62 of the bending plate to a position flush with the top of the interceptor plate 3. This position is the highest position when the bending plate is repeatedly lifted and lowered. Then, solid waste mixed with plastic and other hard materials (metal and glass) is put into the cleaning chamber 4. The drive assembly 7 drives the bending plate to repeatedly lift and lower. During the repeated lifting and lowering, the lowest position of the horizontal part 61 of the bending plate is not lower than the bottom height of the interceptor plate 3. At this time, the cooperation of the vertical part 62 and the interceptor plate 3 can prevent the plastic from entering the separation chamber 5 directly without repeated settling and cleaning, thus ensuring the cleaning effect of the plastic. During the lifting and lowering of the horizontal section 61, the vertical through hole 10 allows liquid to pass through, thereby increasing the turbulence of the cleaning fluid and improving the cleaning effect on plastics and other hard materials (metals and glass). When the plastic is pushed from the cleaning chamber 4 to the separation chamber 5 by the translation of the bending plate 6, the drive assembly 7 drives the bending plate 6 to rise until the bottom end of the vertical section 62 is higher than the plastic on the surface of the cleaning fluid. Then, the entire bending plate 6 is driven to translate away from the separation chamber 5 until the vertical section 62 moves to the end position of the sorting tank 1. Subsequently, the drive assembly 7 moves the bottom end of the vertical section 62 to be level with the surface of the cleaning fluid, and then drives the entire bending plate 6 to translate towards the separation chamber 5 until the vertical section 62 moves directly above the interceptor plate 3.

[0034] In a further preferred embodiment, the drive assembly 7 includes a support frame 71. The top plate of the support frame 71 has parallel guide grooves 72 and a rack 73. The rack 73 is located directly above the cleaning chamber 4 and perpendicular to the interceptor plate 3. A slide block 74 is slidably connected within the guide groove 72. A lifting power device 75 and a travel drive motor 76 are fixedly connected to the slide block 74. The telescopic part of the lifting power device 75 passes through the slide block 74 and is fixedly connected to the bending plate 6. The output shaft of the travel drive motor 76 is fixedly connected to a travel gear 77, which meshes with the rack 73.

[0035] In use, the lifting power unit 75 can be a hydraulic cylinder. The hydraulic cylinder is connected to an oil tank via an oil pump. When the oil pump pumps oil from the hydraulic cylinder into the oil tank, the telescopic part retracts, causing the bending plate 6 to rise. When the oil pump pumps oil from the oil tank into the hydraulic cylinder, the telescopic part extends, causing the bending plate 6 to descend. After the travel drive motor 76 is started, it causes the travel gear 77 to rotate and travel along the length of the rack 73, thereby driving the entire slide block 74 to move along the length of the rack 73.

[0036] In a further preferred embodiment, the sediment conveying assembly 2 includes a first conveyor belt 21, a connector 22, and a second conveyor belt 23 arranged along the length of the sorting tank 1. The first conveyor belt 21 is horizontally arranged, with its two ends respectively fitted onto a first driving roller 24 and a first driven roller 25. Both the first driving roller 24 and the first driven roller 25 are rotatably connected to the side wall of the sorting tank 1. The first driving roller 24 is located at one end of the sorting tank 1 and is connected to a first motor 26. The second conveyor belt 23 is inclined, and its conveying surface is evenly distributed with ridges 27. These ridges 27 prevent the transported material from slipping on the second conveyor belt 23, thus avoiding affecting the conveying effect. The two ends of the second conveyor belt 23 are respectively fitted onto a second driven roller 28 and a second driving roller. The second driven roller 28 is rotatably connected to the side wall of the sorting tank 1 and is located below the first driven roller 25. The second active roller is rotatably connected to the fixed frame on the top surface of the sorting tank 1 and connected to the second motor 29. The connector 22 is used to connect the first conveyor belt 21 and the second conveyor belt 23.

[0037] In operation, the first motor 26 and the second motor 29 drive the first conveyor belt 21 and the second conveyor belt 23 respectively, thereby conveying metals, glass, and other hard materials. The connector 22 provides a sealed connection between the first conveyor belt 21 and the second conveyor belt 23, preventing metals, glass, and other hard materials from falling through the gap between them to the bottom of the sorting tank 1. The horizontal distance between the two far-away ends of the first conveyor belt 21 and the second conveyor belt 23 is greater than the length of the sorting tank 1. A sediment collection box is installed below the conveying end of the second conveyor belt 23, allowing metals, glass, and other hard materials on the conveying end of the second conveyor belt 23 to fall smoothly into the sediment collection box.

[0038] In a further preferred embodiment, the connecting component 22 includes a fixed plate 221, which is fixedly connected to the bottom of the sorting tank 1 and located below the first conveyor belt 21. A plurality of guide rods 222 are fixedly connected to one side of the fixed plate 221, and springs 223 are sleeved on the guide rods 222. One end of the spring 223 is fixedly connected to the fixed plate 221, and the other end of the spring 223 is fixedly connected to a movable plate 224. One side of the movable plate 224 has guide holes corresponding to the guide rods 222. The top surface of the movable plate 224 contacts the bottom surface of the first conveyor belt 21, and the side of the movable plate 224 away from the fixed plate 221 contacts the end of the second conveyor belt 23.

[0039] In use, when the protrusion 27 on the second conveyor belt 23 moves to the movable plate 224, it applies a force to the movable plate 224, causing the movable plate 224 to move towards the fixed plate 221. At this time, the spring 223 is compressed, and the guide rod 222 extends into the guide hole. After the protrusion 27 continues to move and separates from the movable plate 224, the movable plate 224 is reset under the action of the spring 223. During this process, the movable plate 224 is always in contact with the second conveyor belt 23, ensuring the sealing of the connection between the first conveyor belt 21 and the second conveyor belt 23, and effectively preventing other hard materials such as metal and glass from falling into the bottom of the sorting tank 1 through the gap between the first conveyor belt 21 and the second conveyor belt 23.

[0040] In a further preferred embodiment, the plastic discharge assembly 8 includes a support plate 81 fixedly connected to the sorting tank 1. The support plate 81 is parallel to the interceptor plate 3, and the bottom end of the support plate 81 is immersed in the cleaning solution. A lever 82 evenly distributed along the width direction of the sorting tank 1 is rotatably connected to the support plate 81. At least one actuating plate 83 is fixedly connected to the lever 82, and the lever 82 is connected to the rotary drive assembly 84.

[0041] In use, the height of the lever 82 is higher than the top surface of the sorting tank 1, and the lowest position of the lever 83 is lower than the liquid level of the cleaning fluid. The rotation drive assembly 84 drives the lever 82 to rotate in the same direction. When the lever 82 rotates, it can move the plastic floating above the separation chamber 5 in one direction, thereby pushing the plastic out of the sorting tank 1.

[0042] In a further preferred embodiment, the rotary drive assembly 84 includes a third motor 841, a drive gear 842, a driven gear 843, and several transmission gears 844. The third motor 841 is located at one end of the support plate 81. The drive gear 842 is fixedly connected to the output shaft of the third motor 841. The drive gear 842 meshes with the driven gear 843. The driven gear 843 is fixedly connected to one end of one of the levers 82. The transmission gears 844 are fixedly connected to the levers 82. The two transmission gears 844 on two adjacent levers 82 are connected by a toothed belt drive.

[0043] When in use, the third motor 841 starts, causing the driving gear 842 to drive the driven gear 843 to rotate, which in turn drives one of the levers 82 to rotate. Since the two transmission gears 844 on the two adjacent levers 82 are connected by a toothed belt (not shown in the attached diagram of the instruction manual), the lever 82 driven to rotate by the third motor 841 can drive all the other levers 82 to rotate in the same direction.

[0044] In a further optimized design, a drying assembly 11 is located below the plastic discharge port of the plastic discharge assembly 8. The drying assembly 11 includes a water storage tank 111, a drying chamber 112, and a conveyor belt 113. Both the drying chamber 112 and the conveyor belt 113 are fixedly connected to the top surface of the water storage tank 111. Blind curtains 114 are installed at both the inlet and outlet of the drying chamber 112 to prevent plastic from being blown out of the drying chamber 112. Fans 115 are evenly distributed along the length of one side of the drying chamber 112, facing the conveyor belt 113. The other side of the drying chamber 112 is connected to a bag filter 116 via an air outlet. The bag filter 116 prevents air convection within the drying chamber 112 and also prevents small plastic particles from being blown into the air and causing pollution. A filter screen is provided at the air outlet. The conveyor belt 113 runs horizontally through the drying chamber 112. The two ends of the conveyor belt 113 are respectively sleeved on the third driven roller and the third driving roller. The third driven roller and the third driving roller are rotatably connected to the top edge of the water storage tank 111. The third driven roller is located in the groove on the side wall of the sorting tank 1. The third driving roller is connected to the fourth motor 117.

[0045] Before use, a plastic collection box can be installed below the end of the conveyor belt 113. During use, the plastic sent out from the sorting pool 1 falls onto the conveyor belt 113, and the liquid on the plastic falls into the water storage pool 111 through the conveyor belt 113 for collection, avoiding waste of cleaning fluid and pollution of the ground. Then, the plastic enters the drying chamber 112 under the conveyor belt 113. The fan 115 in the drying chamber 112 dries the plastic, and finally it is collected by the plastic collection box.

[0046] In a further optimized design, the actuating plate 83 on the lever 82 near the drying component 11 has a hollow structure.

[0047] When in use, the hollow structure can reduce the amount of cleaning fluid pushed out by the agitator plate 83, thus reducing the frequency of adding cleaning fluid to the sorting tank 1.

[0048] Therefore, the solid waste sorting and processing device of the present invention with the above-described structure can avoid mixing hard materials such as metal and glass into the sorted plastics, and can also improve the cleanliness of the sorted plastics and other recyclables, thereby improving the sorting efficiency.

[0049] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.

[0050] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention.
