Description

Technical Field

[0001] This invention relates to the field of solid waste crushing technology, specifically to a solid waste crushing and treatment device and method. Background Technology

[0002] Solid waste can be divided into household waste and industrial and mining solid waste depending on its source. Among these solid wastes, the largest quantities are mining solid waste generated during the mining and beneficiation process and solid waste generated during industrial production. These solid wastes have complex and diverse compositions, and crushing equipment is needed to pulverize them.

[0003] A solid waste crushing and processing device is disclosed in patent document CN117065857B. Through the layered arrangement of upper and lower processing platforms, the incoming waste can be graded in the vertical direction. After progressive processing, waste particles that meet the standards are obtained. During the processing, the crushing mechanisms located on the upper and lower processing platforms cooperate with each other, so that the transfer process of waste from the upper layer to the lower layer will automatically retain large particles and discharge small particles directly. The crushing and processing is highly targeted, and the upper and lower layer arrangement occupies a small area, effectively saving the space for vertical extension.

[0004] However, this solution still has the following problems in use. Although it can perform multi-stage crushing, the meshing crushing method of the grinding roller and the adapter roller has a large limitation on the size of the material. It cannot adapt well to the crushing of materials of different sizes and types. When the material has a large volume and hardness, it is not easy to enter between the grinding roller and the adapter roller. It will be pushed by the grinding roller and blocked in front of the grinding roller. Not only can it not be crushed well, but it will also prevent other materials from entering between the grinding roller and the adapter roller to participate in the crushing, resulting in a reduction in the crushing efficiency of the equipment. Summary of the Invention

[0005] This invention provides a solid waste crushing and processing device and method, aiming to solve the problem that the meshing crushing method of grinding rollers and adapter rollers in related technologies has a large limitation on the size of materials and cannot well adapt to the crushing and processing of materials of different sizes and types.

[0006] The solid waste crushing and processing apparatus of the present invention includes a body and a crushing unit disposed on the body, and further includes: A conical disc is coaxially rotatably mounted inside the machine body and located below the crusher unit; The crushing component includes a fixed toothed plate and a movable toothed plate. The fixed toothed plate is fixed to the inner wall of the machine body, and the movable toothed plate is set on a conical disk. The conical disk has a radial groove for the movable toothed plate to be installed, and the movable toothed plate can slide radially along the radial groove. The pushing mechanism is located inside the conical disk and connected to the movable toothed plate. As the conical disk rotates, it drives the movable toothed plate to slide radially in the radial groove periodically, so that the distance between the movable toothed plate and the fixed toothed plate changes dynamically.

[0007] Preferably, the push mechanism includes: The central shaft is coaxially fixed inside the machine body, and a closed-loop spiral groove with the beginning and end connected is opened on the central shaft. A ring sleeve is fitted onto the central shaft, and the inner side of the ring sleeve is provided with a protrusion that slides and engages with the sliding groove. The connecting rod has one end connected to the ring sleeve and the other end extending into the radial groove and slidingly connected to the movable toothed plate. When the conical disk rotates, it drives the ring to rotate around the central axis. Through the cooperation of the protrusion and the slide groove, the ring moves back and forth along the central axis, and then drives the movable toothed plate to slide radially through the connecting rod.

[0008] Preferably, the movable toothed plate has a side plate fixed to its side, the side plate is slidably disposed in the radial groove, and the side plate is provided with an inclined part. The end of the connecting rod away from the ring sleeve extends into the radial groove and is slidably assembled on the inclined part of the side plate. When the connecting rod moves with the ring sleeve, its end slides on the inclined part, thereby driving the side plate to move in the radial groove, adjusting the extension length of the movable toothed plate in the radial groove, so as to realize the pressurization of waste material and anti-blockage and unblocking.

[0009] Preferably, the machine body includes a feeding box, which has an upper conical part and a vertical part. The conical disc has an upper conical surface and a vertical surface corresponding to the upper conical part and the vertical part. The upper conical part and the upper conical surface, and the vertical part and the vertical surface together enclose and form an extrusion cavity with a cross-sectional area that gradually decreases from top to bottom. The fixed toothed plate is fixed to the inner wall of the upper conical part and the vertical part, and the movable toothed plate extends into the extrusion cavity.

[0010] Preferably, both the movable toothed plate and the fixed toothed plate are composed of an inclined upper plate and a vertical lower plate. The upper plate is located between the upper cone and the upper cone surface, and the lower plate is located between the vertical part and the vertical surface. The inclination of the upper plate of the movable toothed plate is the same as the inclination of the upper cone surface, and the inclination of the upper plate of the fixed toothed plate is the same as the inclination of the upper cone. This makes the distance between the upper plate of the movable toothed plate and the upper plate of the fixed toothed plate gradually decrease from top to bottom, thereby allowing the waste material to be better gathered between the movable toothed plate and the fixed toothed plate, so as to facilitate the compression and crushing of the waste material.

[0011] Preferably, it also includes a rolling component, the bottom of the conical disc has a lower conical surface, the bottom of the material box has a lower conical part corresponding to the lower conical surface, and a rolling cavity is formed between the two. The rolling component includes a rolling roller and a scraper rotatably mounted on the conical disc. The bottom side of the rolling roller is located above the lower conical part in the rolling cavity. The scraper is located on the side of the rolling roller and fixed to the conical disc. The bottom of the scraper is closely attached to the lower conical part, and the cross-section of the scraper is triangular.

[0012] Preferably, it also includes a transmission mechanism, which includes a gear plate fixed to the machine body and a gear fixed to the end of the rolling roller. The gear meshes with the gear plate. When the conical disc rotates, the gear revolves around the gear plate and rotates on its own axis, thereby driving the rolling roller to roll.

[0013] Preferably, the lower cone is provided with a discharge port, and a screen plate is detachably installed at the discharge port, so that when there is no limitation on the particle size of the crushed waste, the user can remove the screen plate so that the waste can be discharged directly from the discharge port. Alternatively, screen plates with different screen hole diameters can be selected and replaced according to the required particle size of the crushed waste, thereby improving the crushing and discharge effect of the equipment.

[0014] Preferably, the crushing unit consists of crushing rollers and a drive box. There are two crushing rollers, both of which are rotatably assembled inside the machine body. The drive box is located on the machine body and is used to drive the two crushing rollers to rotate in opposite directions.

[0015] A method for crushing and treating solid waste includes the following steps: Step 1: The waste material is initially crushed by the crushing unit; Step 2: The waste material after preliminary crushing enters the extrusion chamber formed by the machine body and the rotating conical disc; Step 3: During the rotation of the conical disc, the moving toothed plate is driven by the pushing mechanism to slide radially periodically, so that it cooperates with the fixed toothed plate to dynamically squeeze and crush the waste material; Step 4: The waste material after being squeezed and crushed enters the crushing chamber and is crushed by the crushing rollers that revolve around and rotate with the conical disc. Step 5: Waste material that has reached the predetermined particle size is discharged through the sieve plate.

[0016] The beneficial effects are: 1. When in use, the present invention uses a pushing mechanism to automatically extend and retract the movable toothed plate during rotation, dynamically adjusting the gap with the fixed toothed plate. This not only increases the squeezing force when it extends, but also allows it to retract in time to clear the material. This improves the squeezing and crushing effect on waste materials, and enables the equipment to intelligently prevent clogging, operate more stably, and better adapt to the crushing of waste materials of different types.

[0017] 2. When in use, this invention combines multiple crushing methods such as shearing, extrusion, and crushing to gradually crush solid waste from coarse to fine, resulting in more thorough crushing and more uniform particle size. The conical structure of the extrusion chamber allows the waste to be naturally compressed during descent, improving the efficiency of the crushing components and making the equipment more efficient and effective.

[0018] 3. When in use, the present invention allows for flexible and controllable discharge particle size through detachable and replaceable screen plates, which can easily adjust the final discharge particle size to meet different process or resource utilization needs, and the equipment has strong adaptability.

[0019] 4. In use, the present invention integrates the two-stage crushing mechanism of extrusion and crushing into the cavity of the conical disc and the material box. It is driven by a single motor and achieves complex actions through a clever mechanical structure. The adjustment mechanism is completely built into and integrated into the core moving component of the rotating conical disc, realizing the integration and automated linkage of crushing action and adjustment action. No additional power source and control system are required, saving space and having relatively low energy consumption, making the equipment structure compact and highly efficient.

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figures 1 to 7 As shown, the solid waste crushing and processing device of the present invention includes a body 10, a crushing unit 20, a conical disc 30, a crushing component 40, a pushing mechanism 50, a crushing component 60, and a transmission mechanism 70. The crushing unit 20 is disposed on the body 10 and is used to perform preliminary crushing processing on the waste entering the body 10. The conical disc 30 is disposed below the crushing unit 20 inside the body 10 and can rotate relative to the body 10. During rotation, the pushing mechanism 50 drives the crushing component 40 to operate and crush the waste. The transmission mechanism 70 drives the crushing component 60 to operate and crush the waste.

[0030] refer to Figure 1 and Figure 2 The machine body 10 includes a crushing box 11, a transfer box 12, and a discharge box 13. The crushing box 11 and the discharge box 13 are respectively fixedly installed on the upper and lower sides of the transfer box 12 and are connected to the transfer box 12 so that the waste in the crushing box 11 can enter the discharge box 13 through the transfer box 12. The crushing unit 20 is set on the crushing box 11. A feed hopper 14 is fixedly installed on the top of the crushing box 11 for adding waste.

[0031] refer to Figure 1 The crushing unit 20 consists of crushing rollers 21 and a drive box 22. There are two crushing rollers 21, both of which are rotatably assembled inside the crushing box 11. The drive box 22 is set on the crushing box 11 and is used to drive the two crushing rollers 21 to rotate in opposite directions, thereby crushing the waste material.

[0032] refer to Figure 2 and Figure 3 The material box 13 is composed of an upper conical part 131, a vertical part 132 and a lower conical part 133. The upper conical part 131 and the lower conical part 133 are respectively arranged on the upper and lower sides of the vertical part 132. The diameter of the upper conical part 131 gradually increases from top to bottom, and the diameter of the lower conical part 133 gradually decreases from top to bottom. The upper conical part 131 is fixed and connected to the transfer box 12. The bottom end of the lower conical part 133 is coaxially fixed with a mounting base 134. The conical disk 30 is coaxially rotatably mounted on the mounting base 134, and a motor is provided on the mounting base 134 to drive the conical disk 30 to rotate.

[0033] refer to Figure 3 The conical disc 30 is provided with an upper conical surface, a vertical surface, and a lower conical surface that are adapted to the material box 13. The upper conical part 131 and the upper conical surface, and the vertical part 132 and the vertical surface together enclose and form an extrusion cavity 135. The crushing component 40 is disposed in the extrusion cavity 135. The distance between the upper conical surface and the upper conical part 131 gradually decreases from top to bottom, so that the cross-sectional area of ​​the extrusion cavity 135 gradually decreases from top to bottom. Therefore, the space of the extrusion cavity 135 gradually decreases from top to bottom. As the waste material enters the extrusion cavity 135 in the material box 13, the space for the waste material to move is gradually compressed, which makes it more convenient for the crushing component 40 to crush the waste material.

[0034] A crushing chamber 136 is formed between the lower cone surface and the lower cone portion 133. The crushing component 60 is disposed inside the crushing chamber 136. A discharge port is also provided on the lower cone portion 133, and a screen plate 137 is provided inside the discharge port for screening waste materials. After the waste materials are crushed and crushed to a suitable particle size, they can pass through the screen plate 137 for discharge. The screen plate 137 and the lower cone portion 133 are detachably connected by bolts, so that when there is no limitation on the crushed particle size of the waste materials, the user can remove the screen plate 137 so that the waste materials can be discharged directly from the discharge port. Alternatively, the user can select and replace the screen plate 137 with a different screen hole diameter according to the required particle size of the crushed waste materials to improve the crushing and discharge effect of the equipment.

[0035] refer to Figure 3 , Figure 5 as well as Figure 6 The conical disc 30 has radial grooves 31, which are evenly distributed in a ring along the circumference of the conical disc 30 and are all connected to the crushing chamber 136 for the installation of the crushing component 40. The conical disc 30 has a circular cavity 32 coaxially connected to the radial grooves 31 for the installation of the pushing mechanism 50. The lower conical surface of the conical disc 30 has an oblique groove 33 for the installation of the crushing component 60. The bottom of the conical disc 30 has an annular groove 34 located on one side of the oblique groove 33 for the installation of the transmission mechanism 70.

[0036] refer to Figure 3 , Figure 5 as well as Figure 6 The crushing component 40 includes a movable toothed plate 41 and a fixed toothed plate 42. Both the movable toothed plate 41 and the fixed toothed plate 42 are composed of an inclined upper plate and a vertical lower plate. The movable toothed plate 41 is disposed in the radial groove 31 and one end extends into the extrusion chamber 135. The inclination of the upper plate of the movable toothed plate 41 is the same as the inclination of the upper conical surface. The upper plate and the lower plate of the fixed toothed plate 42 are respectively fixed to the upper conical part 131 and the vertical part 132. The movable toothed plate 41 is rotated by the rotation of the conical disk 30, so that the movable toothed plate 41 can cooperate with the fixed toothed plate 42 to crush the material. The waste material gathered in the extrusion chamber 135 is extruded and crushed to further reduce the volume of the waste material. The inclination of the upper plate of the movable toothed plate 41 is the same as the inclination of the upper conical surface, and the inclination of the upper plate of the fixed toothed plate 42 is the same as the inclination of the upper conical part 131. This makes the distance between the upper plate of the movable toothed plate 41 and the upper plate of the fixed toothed plate 42 gradually decrease from top to bottom, just like the distance between the upper conical surface and the upper conical part 131. This allows the waste material to gather better between the movable toothed plate 41 and the fixed toothed plate 42, so as to facilitate the extrusion and crushing of the waste material.

[0037] A side plate 411 is fixedly mounted on the movable toothed plate 41 and slidably assembled in the radial groove 31. An inclined part 412 is provided on the side of the side plate 411 away from the movable toothed plate 41. By sliding the side plate 411 in the radial groove 31, the extension length of the movable toothed plate 41 in the radial groove 31 can be adjusted. As the extension length of the movable toothed plate 41 gradually increases, the distance between the movable toothed plate 41 and the fixed toothed plate 42 gradually decreases, thereby applying radial extrusion force to the waste in the extrusion chamber 135, so that the waste can be better crushed. As the extension length of the movable toothed plate 41 gradually decreases, the distance between the movable toothed plate 41 and the fixed toothed plate 42 gradually increases, so that the waste can enter the space between the movable toothed plate 41 and the fixed toothed plate 42 better, effectively avoiding the accumulation and blockage of the waste in the extrusion chamber 135 between the movable toothed plate 41 and the fixed toothed plate 42 due to the arch bridge effect. This allows the conical disk 30 to better crush and extrude the waste during rotation.

[0038] There are multiple movable toothed plates 41 and multiple fixed toothed plates 42. Multiple movable toothed plates 41 are respectively arranged in multiple radial grooves 31, and multiple fixed toothed plates 42 are evenly distributed in a ring in the extrusion chamber 135.

[0039] refer to Figure 3 and Figure 7The pushing mechanism 50 includes a central shaft 51, a ring 52, and a connecting rod 53. The central shaft 51 is coaxially rotatably mounted inside the circular cavity 32. The top end of the central shaft 51 extends and is fixed inside the transfer box 12. The ring 52 is sleeved on the outside of the central shaft 51 and can rotate around the central shaft 51 and slide along the axial direction of the central shaft 51 during rotation. The connecting rod 53 is fixedly mounted on the ring 52. The end of the connecting rod 53 away from the ring 52 extends into the radial groove 31 and is slidably mounted on the inclined portion 412 of the side plate 411. When the conical disk 30 rotates, it pushes the connecting rod 53 so that the ring 52 rotates outside the central shaft 51 and slides axially, thereby driving the connecting rod 53 to slide and rise and fall in the radial groove 31. The end of the connecting rod 53 slides on the inclined portion 412 of the side plate 411 as it rises and falls, thereby driving the side plate 411 to move in the radial groove 31 and adjusting the extension length of the movable toothed plate 41 in the radial groove 31.

[0040] A spiral groove 511 is provided on the central shaft 51, and the grooves 511 are connected end to end to form a closed loop. A protrusion 521 is fixed inside the ring sleeve 52 and slidably disposed in the groove 511. When the ring sleeve 52 rotates, the protrusion 521 slides along the groove 511, causing the ring sleeve 52 to slide back and forth along the axial direction of the central shaft 51, thereby realizing the lifting and lowering of the ring sleeve 52. This allows the side plate 411 to slide in the radial groove 31 as the conical disk 30 rotates, thereby adjusting the extension length of the movable toothed plate 41 in real time.

[0041] refer to Figure 4 and Figure 6 The crushing component 60 includes a crushing roller 61 and a scraper 62. The crushing roller 61 is rotatably mounted inside the inclined groove 33, and the bottom side of the crushing roller 61 is located above the lower cone portion 133 inside the crushing chamber 136. The scraper 62 is located on the side of the crushing roller 61 and fixed to the conical disk 30, with the bottom of the scraper 62 closely attached to the lower cone portion 133. By rotating the conical disk 30, the crushing roller 61 is driven to move within the crushing chamber 136, continuously crushing and pulverizing the waste material entering the crushing chamber 136, so that... Waste material can be discharged through screen plate 137 after reaching the required particle size. The scraper 62 pushes and scrapes up the waste material that adheres to the screen plate 137 after crushing, so that the waste material stuck on the screen plate 137 can enter the mesh of the screen plate 137 better. The cross-section of the scraper 62 is triangular, which allows the scraper 62 to pass under large waste material better without pushing large waste material to move. This prevents the waste material from being stuck between the scraper 62 and the crushing roller 61 and forming a crushing dead angle, thereby improving the crushing and pulverizing effect of the waste material.

[0042] refer to Figure 4The transmission mechanism 70 includes a gear 71 and a gear disk 72. The gear 71 is located in the annular groove 34 and is coaxially fixed to the end of the crushing roller 61. The gear disk 72 is coaxially fixed on the mounting base 134 and meshes with the gear 71. When the conical disk 30 rotates and drives the crushing roller 61 to revolve in the feed box 13, the gear disk 72 pushes the moving gear 71 to rotate, thereby causing the crushing roller 61 to rotate in motion and crush the waste material.

[0043] A method for crushing and treating solid waste includes the following steps: Step 1: The waste material is initially crushed by the crusher unit 20; Step 2: The waste material after preliminary crushing enters the extrusion chamber 135 formed by the machine body 10 and the rotating conical disc 30; Step 3: During the rotation of the conical disk 30, the moving toothed plate 41 is driven by the pushing mechanism 50 to slide radially periodically, so that it cooperates with the fixed toothed plate 42 to dynamically squeeze and crush the waste material. Step 4: The waste material after being squeezed and crushed enters the crushing chamber 136 and is crushed by the crushing roller 61, which revolves around and rotates with the conical disc 30. Step 5: Waste material that has reached the predetermined particle size is discharged through screen plate 137.

[0044] In this invention, the pushing mechanism 50 automatically extends and retracts the movable toothed plate 41 during rotation, dynamically adjusting the gap with the fixed toothed plate 42. This increases the squeezing force when extending and allows for timely retraction to clear the material, improving the crushing effect on waste materials. It also enables the equipment to intelligently prevent clogging, ensuring more stable operation and better adaptability to crushing different types of waste materials. Furthermore, it combines multiple crushing methods such as shearing, extrusion, and rolling to progressively crush solid waste from coarse to fine, resulting in more thorough crushing and more uniform output particle size. The conical structure of the extrusion chamber 135 naturally compresses the waste material during descent, improving the efficiency of the crushing component 40 and making the equipment more efficient and effective. The detachable and replaceable screen plate 137 allows for flexible and controllable output particle size, easily adjusting the final output particle size to meet different process or resource recovery needs, making the equipment highly adaptable. The two-stage crushing mechanism of extrusion and rolling is integrated into the cavity of the cone disc 30 and the discharge box 13. It is driven by a single motor and achieves complex movements through a clever mechanical structure. The adjustment mechanism is completely built into and integrated into the core moving component of the rotating cone disc 30, realizing the integration and automated linkage of crushing and adjustment actions. No additional power source and control system are required, saving space and having relatively low energy consumption, making the equipment compact and highly efficient.

[0045] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
