Abstract
Description
Technical Field
[0001] This invention relates to waste treatment technology, and more particularly to a solid waste treatment system. Background Technology
[0002] Solid waste is diverse, encompassing virtually every type of garbage, primarily originating from solid and semi-solid waste materials generated during production, consumption, daily life, and other activities. Specifically, it includes hard solid particles, slag dust, sludge, waste metal and wood products, plastic shells, vegetable scraps, clothing fabrics, as well as foam and bags. Due to a lack of proper management and sorting, this waste is often dumped in bulk, leading to difficulties in compression during solid waste processing. The mixture of hard waste and soft foam residue prevents effective compression of the residue, resulting in a waste cake with large internal pores, sometimes even making it difficult to form a proper shape. For example, solid waste from industrial production sometimes includes packaging foam, plastic bags mixed with plastic packaging frames and wooden frames, or a mixture of insulation layers and concrete materials from building decoration, all of which make compression difficult during processing. Summary of the Invention
[0003] The purpose of this invention is to provide a solid waste treatment system to solve the problem that in some existing solid waste treatment processes, the mixture of waste materials makes it difficult to compress and process them sufficiently.
[0004] To achieve the above objectives, the present invention provides a solid waste treatment system, comprising a waste conveying device and a compression device. The compression device includes a plurality of horizontally arranged compression chambers. The opening of the first compression chamber is located below the outlet of the waste conveying device. A blowing system is provided on one side between the first compression chamber and the waste conveying device. The blowing system blows air along the arrangement direction of the compression chambers, so that the solid waste falling from the waste conveying device falls into the corresponding compression chamber according to its own weight.
[0005] Furthermore, an extrusion plate is installed on one side of the inner wall of the compression chamber. All extrusion plates are threadedly mounted on a lead screw, which is horizontally rotatably mounted on the compression device. When the lead screw rotates, all extrusion plates horizontally extrude solid waste in the compression chamber.
[0006] Furthermore, the extrusion plate has a rectangular plate structure, and the two opposite sides of the extrusion plate slide in fit with the two opposite sides of the compression chamber.
[0007] Furthermore, a guide rod is horizontally provided through the extrusion plate, and when the lead screw rotates, the extrusion plate moves horizontally under the action of the guide rod.
[0008] Furthermore, a threaded ring is coaxially threaded onto the lead screw, and the extrusion plate is fitted inside the threaded ring. Between the extrusion plate and the threaded ring, there are several tension springs that are always in a compressed state along the axial direction of the threaded ring. The tension springs make the threaded ring and the extrusion plate a single unit.
[0009] Furthermore, the clamping springs are arranged in a ring array within the threaded ring, and each clamping spring makes contact with the surface of the extrusion plate through a friction plate.
[0010] Furthermore, the bottom plate of the compression chamber is hinged to a column in the center via an ear plate, and a support arm is symmetrically hinged to both sides of the column. The free end of the support arm abuts against the bottom plate so that the bottom plate is in a horizontal position. The end face of the bottom plate near the extrusion plate is an arc surface so that the bottom plate does not contact or interfere with the extrusion plate when it is hinged and rotated on the column.
[0011] Furthermore, the bottom of the ear plate has a rectangular strip plate;
[0012] The support arm includes a bearing plate, a diagonal brace, and an abutment plate. The diagonal brace is L-shaped, with its corner hinged to the side of the column, and the included angle opening of the corner facing away from the column. The bearing plate is fixedly connected to the top of the diagonal brace, and the abutment plate is fixedly connected to the bottom of the diagonal brace. When the silo bottom plate is in a horizontal position, the bearing plate is horizontally pressed against the silo bottom plate, and the abutment plate is vertically set and abuts against the side of the strip plate through a horizontally arranged bearing member.
[0013] Furthermore, at least one of the supporting components is a horizontally positioned hydraulic rod, the free end of which contacts the abutment plate.
[0014] Another structure is that, below the compression device, the present invention also has a horizontally arranged conveyor belt for transporting the compressed garbage cake; the carrier includes a rectangular column and a cylindrical rod, the first cylindrical rod of the carrier on the left side is horizontally slidably inserted into the first rectangular column and elastically contacting the first rectangular column; the second cylindrical rod of the carrier on the right side is integrally fixed to the second rectangular column.
[0015] On the wall of the insertion hole of the first rectangular column for the insertion of the first cylindrical rod, there is an axially oriented groove, and a first contact block is axially slidably disposed in the groove. The first contact block is connected in the groove by a return spring. A second contact block is fixedly connected to the side wall of the end of the first cylindrical rod that is inserted into the insertion hole. When the first contact block and the second contact block are in contact, the circuit of the drive motor of the conveyor belt is turned on.
[0016] Beneficial effects: This invention uses an air-separation grading structure to screen solid waste of different weights. It can coarsely screen some waste such as stone, concrete, steel frame, sheet metal shell, and wooden frame, as well as lightweight waste such as cloth, plastic bags, and vegetable leaves. This allows waste of different weights to fall into the corresponding compression chambers, avoiding the serious impact on the compression degree caused by some wastes being difficult to compress and large in size. It can make the compressed solid waste cake more uniform and facilitate automatic discharge and transportation. Compared with some existing extensive mixed compression treatments, the equipment is not complicated and the cost is not high, but it has a certain improvement in effect and is worth promoting and using.

[0025] The embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0026] The solid waste treatment system of this embodiment mainly includes a waste conveying device 1 and a compression device 2. The waste conveying device 1 is used to transport solid waste to the treatment location, while the compression device 2 is used to compress the solid waste for subsequent transfer and disposal. Figure 1 Specifically, it may include several horizontally arranged compression chambers 4. The opening of the first compression chamber is located below the outlet of the waste conveying device 1, and a blowing system 3 is provided on one side between the first compression chamber and the waste conveying device 1. The blowing system 3 blows air along the arrangement direction of the compression chambers 4, i.e. Figure 1 As shown, the solid waste is blown horizontally to the right, causing it to fall into the corresponding compression chamber 4 according to its weight. The heavier solid waste falls directly into the first compression chamber, while the remaining solid waste falls into the subsequent corresponding compression chambers 4. For example, in actual production, garbage bags, strips of cloth, etc., can fall into the third or fourth compression chamber 4. This allows the garbage to be naturally and reasonably dispersed in the corresponding compression chambers 4 according to its weight, so that the solid waste in the same compression chamber 4 can be compressed to a consistent degree. This ensures that the solid waste in each compression chamber 4 can be compressed more fully, completely avoiding the situation where solid waste such as stones falls into the compression chamber 4 containing plastic bags, and preventing the presence of different materials such as stones, concrete blocks, and iron blocks that are difficult to compress. This ensures that the waste in each compression chamber 4 is compressed into a uniform garbage cake, making the structure very simple and reliable.
[0027] like Figures 1-2 As shown, an extrusion plate 5 is also installed on one side of the inner wall of the compression chamber 4. All extrusion plates 5 are threadedly installed on a lead screw 6. The lead screw 6 is horizontally rotatably installed on the compression device 2. When the lead screw 6 rotates, all extrusion plates 5 horizontally extrude solid waste in the compression chamber 4, thereby realizing the linkage of all extrusion plates 5 and simplifying the transmission mechanism and power supporting equipment.
[0028] More specifically, in this embodiment, the extrusion plate 5 is processed into a rectangular plate structure, and the corresponding compression chamber 4 is also a rectangular structure. In this case, the two opposite sides of the extrusion plate 5 and the two opposite sides of the compression chamber 4 are in sliding engagement, so that when the lead screw 6 rotates, the extrusion plate 5 moves linearly back and forth, realizing the extrusion and release of waste. Alternatively, it can be as follows... Figure 2 A guide rod 22 is also horizontally provided on the extrusion plate 5. When the lead screw 6 rotates, the extrusion plate 5 moves horizontally under the action of the guide rod 22.
[0029] To avoid inconsistent compression levels in different compartments during compression by all compression plates 5, where if one difficult-to-compress compartment reaches its limit, all compression compartments 4 may be unable to continue compressing normally, this embodiment addresses this issue by... Figure 3-4 A threaded ring 7 is coaxially threaded onto the lead screw 6, and a compression plate 5 is fitted inside the threaded ring 7. Several tension springs 8, always in a compressed state, are located between the compression plate 5 and the threaded ring 7 along the axial direction of the threaded ring 7. The tension springs 8 connect the threaded ring 7 and the compression plate 5 as a single unit. If the compression chamber 4 reaches its limit, further rotation of the lead screw 6 will inevitably overcome the elastic force of the corresponding tension spring 8, causing the compression plate 5 to rotate relative to the threaded ring 7 and slip. This does not prevent the lead screw 6 from rotating, allowing the compression plates 5 in the remaining compression chambers 4 to continue moving smoothly. In actual manufacturing, the tension springs 8 are arranged in a ring array within the threaded ring 7, and each tension spring 8 makes contact with the surface of the compression plate 5 through a friction plate 9.
[0030] Regarding the discharge of the compressed solid waste cake, in this embodiment, as follows: Figure 1 and Figure 5 The structure shown has a bottom plate 10 of the compression chamber 4 hinged to a column 11 via an ear plate in the center. A support arm is also symmetrically hinged to both sides of the column 11. The free end of the support arm abuts against the bottom plate 10 so that the bottom plate 10 is in a horizontal position. At the same time, the end face of the bottom plate 10 near the extrusion plate 5 is an arc surface so that the bottom plate 10 does not contact or interfere with the extrusion plate 5 when it is hinged and rotated on the column 11. When it is necessary to discharge the waste cake, the extrusion plate 5 first retracts to its original position, and then the bottom plate 10 rotates to push out and drop the waste cake, which is then discharged.
[0031] As a better implementation structure, the bottom of the ear plate in this embodiment has a rectangular strip plate 16. Meanwhile, in this embodiment, the support arm includes a bearing plate 12, a diagonal brace 13, and an abutment plate 14. The diagonal brace 13 is L-shaped, with its corner hinged to the side of the column 11, and the included angle opening of the corner facing away from the column 11. The bearing plate 12 is fixed to the top of the diagonal brace 13, and the abutment plate 14 is fixed to the bottom of the diagonal brace 13. Specifically, it can be integrally formed. In use, when the bottom plate 10 is in a horizontal position, the bearing plate 12 is horizontally close to the bottom plate 10, and the abutment plate 14 is vertically set and abuts against the side of the strip plate 16 through the horizontally arranged bearing member 15. At this time, the extrusion plate 5 moves horizontally, which can stably extrude and compress the garbage in the compression chamber 4.
[0032] Another specific implementation detail is that at least one of the bearing components 15 is a horizontally placed hydraulic rod, the free end of which contacts the contact plate 14. By controlling the extension and retraction of the hydraulic rod, the movement of the bin bottom plate 10 can also be assisted in controlling the position of the bin bottom plate 10, so as to better compress and discharge the compressed garbage cake.
[0033] As a more complete implementation structure, in this embodiment, such as Figure 1 Below the compression device 2, a horizontal conveyor belt 18 is also provided for transporting the compressed waste cake. The waste cake falls onto the conveyor belt 18 and then moves forward for waste transfer processing. For example, Figure 5 The support member 15 includes a rectangular column and a cylindrical rod. The first cylindrical rod 1501 of the support member 15 on the left side is horizontally slidably inserted into the first rectangular column 1502 and elastically contacts the first rectangular column 1502. This elastic contact can be achieved by using a cylindrical spring 1503. The second cylindrical rod 1506 and the second rectangular column 1505 of the support member 15 on the right side are integrally fixed together; that is, the support member 15 on the right side is a rigid element. The above structure is designed primarily because... Figure 5 As shown, the cylindrical rod and the rectangular column are the same size. Initially, the ends of the rectangular column are pressed against the two opposite sides of the strip plate 16. If the bottom plate 10 rotates counterclockwise, the upper edge of the first rectangular column 1502 on the left side will contact the left side wall of the right-inclined strip plate 16 with a length of K, while the lower edge of the second rectangular column 1505 on the right side will contact the right arm of the right-inclined strip plate 16 with a length of L. Since the included angle between the left side wall and the right arm of the strip plate 16 is the same, both are α, then K = h * tan α, L = H * tan α. H must be greater than h, so L must be greater than K. It can be seen that within the 90-degree angle range of the counterclockwise rotation of the bottom plate 10, the bearing member 15 on the left side will definitely bend or retract; otherwise, the bottom plate 10 will not be able to continue rotating.
[0034] For the elastic telescopic structure of the bearing member 15 on the left, such as Figure 6 On the wall of the insertion hole of the first rectangular post 1502 for the insertion of the first cylindrical rod 1501, there is an axially oriented groove 1504. A first contact block 20 is axially slidably provided in the groove 1504. The first contact block 20 is connected to the groove 1504 by a return spring 19. A second contact block 21 is fixedly connected to the side wall of the end of the first cylindrical rod 1501 that is inserted into the insertion hole. The two contacts are respectively connected to wires 17 so that when the bottom plate 10 rotates, the first cylindrical rod 1501 slides into the first rectangular post 1502 and the two contacts come into contact. That is, when the first contact block 20 and the second contact block 21 come into contact, the circuit of the drive motor of the conveyor belt 18 is turned on so that the subsequent conveyor belt 18 can transport the falling solid waste garbage cake.
[0035] The above description discloses only one preferred embodiment of the present invention, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that all or part of the processes of the above embodiments can be implemented, and equivalent changes made in accordance with the claims of the present invention are still within the scope of the invention.
