Description

Technical Field

[0001] This invention relates to the field of industrial solid waste treatment technology, specifically to an industrial solid waste treatment device. Background Technology

[0002] Industrial solid waste, also known as solid waste, generally refers to solid and semi-solid waste materials generated by humans in production, consumption, daily life, and other activities. To reduce the environmental pollution caused by industrial solid waste, it needs to be treated after recycling. This treatment process includes drying the industrial solid waste and then feeding it into a pellet mill to compress it into strip-shaped pellets. The compressed pellets are then cut by a cutting plate and fall onto the conveyor ring of the pellet mill before being discharged for later use.

[0003] When solid waste pellet mills process industrial solid waste, the extruded strip-shaped pellets are usually discharged from the discharge port through a guide plate. If the guide plate is too long, it will hinder the cutting plate from moving in a circular motion with the conveyor ring. If the guide plate is too short, some material will pass through the gap between the guide plate and the solid waste pellet mill, causing the material to keep rotating with the conveyor ring. As a result, some material will not be discharged from the discharge port, thus reducing the feeding speed and resulting in poor feeding effect. Summary of the Invention

[0004] This invention provides an industrial solid waste treatment device. By setting the guide plate as a telescopic structure, it avoids gaps between the guide plate and the outer wall of the extrusion hole, and also does not obstruct the cutting plate from passing through the guide plate. This solves the problems mentioned in the background art, where when the guide plate is too long, it hinders the cutting plate from rotating with the conveyor ring, and when the guide plate is too short, some material passes through the gap between the guide plate and the solid waste pellet mill, causing the material to rotate with the conveyor ring and thus some material will not be discharged from the discharge port, reducing the feeding speed.

[0009] As an optional embodiment of the industrial solid waste treatment device of the present invention, the second baffle has a receiving groove inside, and a first spring is fixed between the inner wall of the receiving groove and the end of the first baffle.

[0010] As an optional embodiment of the industrial solid waste treatment device of the present invention, a rotating rod is fixed on the connecting ring, and the cutting plate is elastically disposed on the circumference of the rotating rod. The cutting plate rotates by abutting against the guide plate. A scraper is elastically disposed on the surface of the cutting plate, and the scraper scrapes the end of the cutting plate by rotating the cutting plate.

[0011] As an optional embodiment of the industrial solid waste treatment device of the present invention, a rotating block is rotatably arranged inside the cutting plate, the rotating block is fixed on the circumference of the rotating rod, a first transmission rod is fixed on the surface of the rotating block, a first hydraulic oil groove is opened inside the cutting plate, a first piston plate is slidably arranged inside the first hydraulic oil groove, and the first piston plate is fixed to the first transmission rod.

[0012] As an optional embodiment of the industrial solid waste treatment device of the present invention, the cutting plate has a second hydraulic oil tank that communicates with the first hydraulic oil tank. A second piston plate is slidably arranged in the second hydraulic oil tank. A second transmission rod is fixed on the second piston plate. A sliding rod is fixed on the surface of the scraper. A limiting groove for the sliding rod to slide is provided on the cutting plate. The end of the second transmission rod is fixed to the sliding rod.

[0013] As an optional embodiment of the industrial solid waste treatment device of the present invention, a pusher plate is slidably provided at the end of the cutting plate, a moving groove is provided inside the cutting plate, a moving block is elastically provided in the moving groove, a sliding groove is provided on the moving block, a push rod is fixed on the pusher plate, and the push rod slides inside the sliding groove to cause the pusher plate to extend and retract to push the material.

[0014] As an optional embodiment of the industrial solid waste treatment device of the present invention, the cutting plate has a third hydraulic oil tank that communicates with the second hydraulic oil tank. A third piston plate is slidably arranged in the third hydraulic oil tank. A third transmission rod is fixed on the surface of the third piston plate. A protrusion is fixed on the surface of the moving block. The protrusion is fixed to the third transmission rod.

[0015] As an optional embodiment of the industrial solid waste treatment device of the present invention, the end of the push rod is fixed with a sliding protrusion, and the inner wall of the sliding groove is provided with a trajectory groove for the sliding protrusion to slide. The trajectory groove includes an extension and a retracting part that are connected together.

[0016] The present invention has the following beneficial effects:

[0017] 1. In this industrial solid waste treatment device, when the guide plate guides the material on the conveying ring, it first ensures that the guide plate fully intercepts the material on the conveying ring, avoiding gaps between the guide plate and the outer wall of the extrusion hole. This allows the material to be discharged from the discharge port along the guide plate, thereby increasing the feeding speed. Simultaneously, by setting the guide plate as a telescopic structure, when the cutting plate rotates with the conveying ring to the guide plate, the end of the cutting plate abuts against the second baffle, causing the second baffle to retract relative to the first baffle. This allows the second baffle to slide along the surface of the cutting plate, avoiding obstruction and facilitating the cutting plate's passage through the guide plate. Thus, while increasing the feeding speed, it does not affect the normal rotation of the cutting plate, resulting in better performance.

[0018] 2. In this industrial solid waste treatment device, after the second baffle contacts the first inclined surface of the cutting plate, the second baffle first retracts relative to the first baffle. When the end of the second baffle slides to the connection between the first and second inclined surfaces, the second baffle can no longer retract. As the cutting plate continues to rotate, the second baffle contacts the second inclined surface of the cutting plate, causing the cutting plate to rotate counterclockwise around the rotating rod. When the cutting plate rotates counterclockwise, the scraper can move upward along the first inclined surface of the cutting plate, so that the scraper can clean the cutting edge of the cutting plate, making it easier to remove the garbage attached to the cutting edge of the cutting plate. This avoids the problem that the contact area between the garbage and the material is too large due to the garbage covering the cutting edge of the cutting plate, which would hinder the cutting edge of the cutting plate from cutting the material, thus making the cutting effect better.

[0019] 3. In this industrial solid waste treatment device, when the second baffle slides along the second inclined surface of the cutting plate, the rotation of the cutting plate drives the pusher plate to reciprocate back and forth. This allows the pusher plate to push the material at the end of the cutting plate, thus pushing the material at the end of the cutting plate forward a certain distance before the second baffle extends and resets. This prevents the material from accumulating at the end of the cutting plate and affecting the reset of the second baffle. It also prevents the material from being stuck by the second baffle, which would affect the feeding effect, and further improves the feeding speed. Attached Figure Description

[0033] 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.

[0034] Example 1, please refer to Figures 1-12 An industrial solid waste treatment device includes a solid waste pellet mill body 1, a plurality of extrusion holes 2 for discharging material are provided on the solid waste pellet mill body 1, a fence 3 is fixedly provided on the edge of the solid waste pellet mill body 1, a conveying ring 4 is rotatably provided between the fence 3 and the extrusion holes 2, and a discharge port 5 is fixed on the outer surface of the fence 3.

[0035] A connecting ring 6 is fixed on the inner side of the conveying ring 4. A cutting plate 7 is provided on the connecting ring 6 for cutting the material extruded from the extrusion hole 2. A guide plate 8 for guiding the material into the discharge port 5 is fixed on the inner surface of the fence 3. The cutting plate 7 abuts against the end of the guide plate 8 by rotating, causing the guide plate 8 to extend and retract.

[0036] A toothed ring 9 is fixed on the lower surface of the conveying ring 4. The toothed ring 9 is rotatably set inside the solid waste pellet mill body 1. A servo motor 10 is fixedly installed inside the solid waste pellet mill body 1. A gear 11 that meshes with the toothed ring 9 is fixed at the output end of the servo motor 10.

[0037] The guide plate 8 includes a first baffle 81 and a second baffle 82. One end of the first baffle 81 is fixed to the fence 3, and the other end of the first baffle 81 is elastically disposed in the second baffle 82.

[0038] The second baffle 82 has a storage groove 12 inside, and a first spring 13 is fixed between the inner wall of the storage groove 12 and the end of the first baffle 81.

[0039] In this technical solution, the top of the solid waste pellet mill body 1 is provided with a feed inlet 39 for feeding in industrial solid waste. The solid waste pellet mill body 1 then processes the industrial solid waste, extruding it from the extrusion hole 2 to form strip-shaped material. Simultaneously, the servo motor 10 drives the gear 11 to rotate, the gear 11 drives the gear ring 9 to rotate, the gear ring 9 drives the conveying ring 4 to rotate, the conveying ring 4 drives the connecting ring 6 to rotate, and the connecting ring 6 drives the cutting plate 7 to rotate. This allows the cutting plate 7 to cut the strip-shaped material, and the cut material falls onto the conveying ring 4. When the conveying ring 4 rotates to the guide plate 8, the material is guided by the guide plate 8 and discharged at the discharge port 5 for subsequent use as fuel. The structure and working principle of the solid waste pellet mill body 1 extruding industrial solid waste are existing technologies and are not the innovation of this application, so they will not be described in detail.

[0040] When the guide plate 8 blocks the material and discharges it from the discharge port 5, if the guide plate 8 is too long, it will hinder the cutting plate 7 from rotating with the connecting ring 6. If the guide plate 8 is too short, some material will pass through the gap between the guide plate 8 and the extrusion hole 2, causing the material to rotate with the conveying ring 4 and not be discharged from the discharge port 5, thus reducing the feeding speed. To address this problem, the guide plate 8 in this application is designed as a telescopic structure. First, the guide plate 8 includes a first baffle 81 and a second baffle 82. During normal feeding, the end of the second baffle 82 is in contact with the outer wall of the extrusion hole 2, reducing the feeding speed. The low clearance allows the material on the conveying ring 4 to be discharged from the discharge port 5 through the guide plate 8. Then, when the cutting plate 7 rotates to the guide plate 8, the cutting plate 7 abuts against the end of the second baffle 82, causing the second baffle 82 to slide relative to the first baffle 81. This causes the first baffle 81 to retract into the receiving groove 12, while compressing the first spring 13 and storing force. This changes the overall length of the guide plate 8, allowing the second baffle 82 to slide along the surface of the cutting plate 7. This prevents the guide plate 8 from being too long and hindering the movement of the cutting plate 7, thus improving the fullness of material feeding.

[0041] In Example 2, during the process of cutting the material by the cutting plate 7, some flaky debris may be coated on the surface of the blade of the cutting plate 7. This increases the contact area between the blade and the material, hindering the cutting of the material and reducing the cutting effect. The cut material tends to form shorter particles, which are less effective than longer particles. Longer particles can balance the reaction contact area and reduce material loss, and they also have a longer combustion time and better performance. To address this issue, this example is an improvement based on Example 1. For details, please refer to [link / reference]. Figures 1-12 A rotating rod 14 is fixed on the connecting ring 6. The cutting plate 7 is elastically set on the circumference of the rotating rod 14. The cutting plate 7 rotates by contacting the guide plate 8. A scraper 15 is elastically set on the surface of the cutting plate 7. The scraper 15 scrapes the end of the cutting plate 7 by rotating the cutting plate 7.

[0042] The cutting plate 7 has a rotating block 16 inside, which is fixed on the circumference of the rotating rod 14. The surface of the rotating block 16 is fixed with a first transmission rod 17. The cutting plate 7 has a first hydraulic oil groove 18 inside, and a first piston plate 19 is slidably arranged inside the first hydraulic oil groove 18. The first piston plate 19 is fixed with the first transmission rod 17.

[0043] The cutting plate 7 has a second hydraulic oil groove 20 that communicates with the first hydraulic oil groove 18. A second piston plate 21 is slidably arranged in the second hydraulic oil groove 20. A second transmission rod 22 is fixed on the second piston plate 21. A sliding rod 23 is fixed on the surface of the scraper 15. A limiting groove 24 for sliding the sliding rod 23 is provided on the cutting plate 7. The end of the second transmission rod 22 is fixed to the sliding rod 23.

[0044] In this technical solution, the cutting plate 7 includes a first inclined surface 71 and a second inclined surface 72. A rotating groove 36 is formed inside the cutting plate 7, and a torsion spring 37 is installed inside the rotating groove 36. The torsion spring 37 is sleeved on the circumference of the rotating rod 14. One end of the torsion spring 37 is fixed to the inner wall of the rotating groove 36, and the other end is fixed to the rotating rod 14. This allows the torsion spring 37 to store force when the cutting plate 7 rotates around the rotating rod 14, facilitating the subsequent reset of the cutting plate 7. Furthermore, the force required for the torsion spring 37 to rotate is greater than the force of the first spring 13 being compressed. After the cutting plate 7 rotates to contact the guide plate 8, the second baffle 82 first... The end of the guide plate 8 first contacts the first inclined surface 71 of the cutting plate 7. At this time, the first spring 13 is compressed first, while the torsion spring 37 does not move, causing the guide plate 8 to shorten as a whole. The cutting plate 7 remains unchanged. During the shortening process of the guide plate 8, the second baffle 82 slides along the surface of the first inclined surface 71 and the scraper 15 until the second baffle 82 slides to the connection between the first inclined surface 71 and the second inclined surface 72. Then the second baffle 82 can no longer retract relative to the first baffle 81, and the guide plate 8 shortens to its shortest length. Then the cutting plate 7 continues to rotate, and the second baffle 82 contacts the second inclined surface 72 of the cutting plate 7. Figure 4 As shown, when the second baffle 82 contacts the second inclined surface 72 of the cutting plate 7, since the second baffle 82 cannot continue to shorten and the second inclined surface 72 protrudes outward, the second baffle 82 will exert a rightward pushing force on the second inclined surface 72, causing the cutting plate 7 to rotate counterclockwise around the rotating rod 14, thus storing force in the torsion spring 37. Figure 9 and Figure 10 As shown, when the cutting plate 7 rotates counterclockwise around the rotating rod 14, the rotating block 16 rotates relative to the cutting plate 7, causing the rotating block 16 to drive the first transmission rod 17 to move. The first transmission rod 17 drives the first piston plate 19 to slide inside the first hydraulic oil tank 18, filling the hydraulic oil inside the first hydraulic oil tank 18 into the second hydraulic oil tank 20 through the first oil guide pipe 40. Figure 11 As shown, when the second hydraulic oil tank 20 is filled with hydraulic oil, the second piston plate 21 moves upward. The second piston plate 21 drives the slide rod 23 to move upward along the limiting slide groove 24 through the second transmission rod 22. A second spring 38 is fixed between the slide rod 23 and the inner wall of the limiting slide groove 24. The slide rod 23 moves upward along the limiting slide groove 24, compressing the second spring 38 and causing the second spring 38 to store force. At the same time, the slide rod 23 drives the scraper 15 to slide upward along the first inclined surface 71 of the cutting plate 7, so that the scraper 15 cleans the cutting edge of the cutting plate 7, making it easier to remove the garbage attached to the cutting edge of the cutting plate 7, and making the cutting effect better.

[0045] In Example 3, after the cutting plate 7 rotates past the guide plate 8, the guide plate 8 loses the resistance of the cutting plate 7 and needs to extend and reset. Because some material accumulates at the end of the cutting plate 7 during rotation, it affects the movement of the guide plate 8 during its extension and reset, preventing it from resetting properly. This results in some material getting stuck between the guide plate 8 and the outer wall of the extrusion hole 2, preventing discharge and thus blocking other materials and reducing the discharge efficiency. This example addresses this problem by improving upon Example 2. For details, please refer to [link to example 2]. Figures 1-12 A pusher plate 25 is slidably provided at the end of the cutting plate 7. A moving groove 26 is provided inside the cutting plate 7. A moving block 27 is elastically provided in the moving groove 26. A sliding groove 28 is provided on the moving block 27. A push rod 29 is fixed on the pusher plate 25. The push rod 29 slides inside the sliding groove 28 to make the pusher plate 25 extend and retract to push the material.

[0046] The cutting plate 7 has a third hydraulic oil groove 30 that communicates with the second hydraulic oil groove 20. A third piston plate 31 is slidably arranged in the third hydraulic oil groove 30. A third transmission rod 32 is fixed on the surface of the third piston plate 31. A protrusion 33 is fixed on the surface of the moving block 27. The protrusion 33 is fixed to the third transmission rod 32.

[0047] The end of the push rod 29 is fixed with a sliding protrusion 34, and the inner wall of the sliding groove 28 is provided with a track groove 35 for the sliding protrusion 34 to slide. The track groove 35 includes an extension 351 and a retraction 352 that are connected together.

[0048] In this technical solution, when the second baffle 82 slides along the second inclined plane 72 and the cutting plate 7 rotates counterclockwise around the rotating rod 14, the hydraulic oil inside the second hydraulic oil tank 20 will also be injected into the third hydraulic oil tank 30 through the second oil guide pipe 41, causing the third piston plate 31 to move to the right. Figure 12As shown, when the third piston plate 31 moves to the right, the third transmission rod 32 drives the protrusion 33 to move to the right. The protrusion 33 drives the moving block 27 to move to the right within the moving groove 26. A third spring 42 is fixed between the moving block 27 and the interior of the moving groove 26. The movement of the moving block 27 to the right pulls the third spring 42, causing the third spring 42 to store force, which facilitates the subsequent reset of the moving block 27. At the same time, the push rod 29 moves to the left along the sliding groove 28. The push rod 29 drives the sliding protrusion 34 to slide along the track groove 35. First, the sliding protrusion 34 slides along the protrusion 351 of the track groove 35, causing the sliding protrusion 34 to drive the push rod 29 to move downward. The push rod 29 pushes the pusher plate 25 to move downward, causing the pusher plate 25 to push the cutting plate 7. The material at the end is pushed away, and then the sliding protrusion 34 slides along the retracted part 352 of the track groove 35, causing the push rod 29 to move upward. The push rod 29 drives the push plate 25 to move upward and reset. At this time, the second baffle 82 slides along the second inclined surface 72 to the end of the cutting plate 7. Then the cutting plate 7 continues to rotate, and the second baffle 82 loses the resistance of the cutting plate 7. The second baffle 82 extends and resets, and the cutting plate 7 rotates clockwise to reset. Through the above process, the material at the end of the cutting plate 7 can be pushed forward a certain distance before the second baffle 82 extends and resets, avoiding the accumulation of material at the end of the cutting plate 7, which would affect the reset of the second baffle 82. At the same time, it can also avoid the problem of the material being stuck by the second baffle 82, which would affect the feeding effect.

[0049] In this technical solution, no extrusion holes 2 are opened in a small section of the solid waste pellet mill body 1 near the end of the second baffle 82, so as to avoid the extruded material directly contacting the end of the second baffle 82, and when the cutting plate 7 rotates to the second baffle 82, the material just extruded from the extrusion hole 2 affects the counterclockwise rotation of the cutting plate 7.

[0050] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0051] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
