Description

Technical Field

[0001] The present invention belongs to the technical field of solid waste treatment, and specifically relates to a solid waste treatment device. Background Art

[0002] Solid waste refers to solid and muddy substances discarded in human production and living activities, abbreviated as solid waste, including solid particles separated from wastewater and waste gas. All substances that are generated during all human activities and are no longer of use value to the owner and are discarded in solid or semi-solid form are generally referred to as solid waste.

[0003] With the development of social economy and the improvement of residents' living standards, the garbage output has been increasing year by year, and garbage treatment has become one of the important environmental problems.

[0004] The main methods of harmless garbage treatment mainly include composting, landfill and heat treatment. Heat treatment has gradually become the main treatment method due to its advantages of harmlessness, reduction and resource utilization. Heat treatment can be divided into methods such as combustion, pyrolysis, and gasification. The combustion process is relatively simple and the product (electricity) is easy to sell, making it the main treatment process in the market. However, the problem of secondary pollution such as dioxin generated during the combustion process is still prominent. Compared with combustion, the pyrolysis process using anoxic reaction can reduce or even eliminate the generation of dioxin in principle, and the pyrolysis products (gas, oil, carbon) can be used as chemical raw materials, with extremely high potential economic value. Therefore, after combustion, pyrolysis is very likely to become the next-generation mainstream garbage treatment technology.

[0005] In the prior art, waste is generally classified for treatment because the optimal pyrolysis conditions for different types of garbage in organic waste are different, such as different temperatures and pyrolysis times. In the actual pyrolysis operation process, there are also co-pyrolysis reactions of different types of waste. Therefore, classifying solid waste is an issue that needs to be considered in the present invention. Summary of the Invention

[0006] Aiming at the deficiencies of the above prior art, the technical problem to be solved by the embodiments of the present invention is to provide a solid waste treatment device.

[0007] To solve the above technical problems, the present invention provides the following technical solutions: A solid waste treatment device, including an outer fixed cylinder and a feeding hopper.

[0032] The technical solutions of the present application will be further described in detail below in conjunction with the specific implementation manners.

[0033] The embodiments of the present application will be described in detail below. The examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation to the present application.

[0034] Please refer to Figures 1 to 12, in one embodiment, a solid waste treatment device includes an outer fixed cylinder 1 and a feeding hopper 2. The feeding hopper 2 is arranged at the top of the outer fixed cylinder 1. The device further includes a bottom plate 4, a mesh cover 40, a driving assembly 3, a pressing plate 5 and a sealing plate 15. The bottom plate 4 is rotatably installed inside the outer fixed cylinder 1. The output end of the driving assembly 3 is connected to the bottom plate 4. A mesh cover 40 is fixedly installed on the outer periphery of the bottom plate 4. The mesh cover 40 is of a conical structure and inclines towards the outside. The driving assembly 3 is used to drive the mesh cover 40 and the bottom plate 4 to rotate. The feeding hopper 2 is communicated with the mesh cover 40. One end of the outer fixed cylinder 1 is detachably installed with a sealing plate 15. A threaded rod 16 is fixedly installed on the outer fixed cylinder 1. The threaded rod 16 penetrates through the bottom plate 4 and is rotatably connected to the bottom plate 4. One end of the threaded rod 16 away from the bottom plate 4 is threadedly connected with a pressing plate 5. A support rod 9 is fixedly installed on the outer peripheral surface of the pressing plate 5. The support rod 9 penetrates through the mesh cover 40 and is slidably connected to the mesh cover 40. A flexible leakage net 6 is installed between the support rods 9. One end of the support rod 9 away from the pressing plate 5 is movably installed with a scraping plate 21.

[0035] In this embodiment, the feeding hopper 2 is arranged at one end close to the bottom plate 4. An aggregate trough 14 is arranged below the open end of the outer fixed cylinder 1. A number of mesh holes are densely arranged on the mesh cover 40. The driving assembly 3 includes a first motor 31, a driving gear 32 and a toothed ring 33. The first motor 31 is installed at one end of the outer fixed cylinder 1. The output end of the first motor 31 is connected to the driving gear 32. A toothed ring 33 is fixedly installed on the bottom plate 4. The toothed ring 33 is meshed and connected with the driving gear 32. The bottom plate 4 is a solid plate. The bottom plate 4 is rotatably connected to the smooth rod section of the threaded rod 16. Both ends of the threaded rod 16 are smooth rods, that is, the pressing plate 5 can freely rotate at the smooth rod position of the threaded rod 16. A limiting plate 160 is installed at one end of the threaded rod 16. The limiting plate 160 is used to limit the position of the pressing plate 5 to prevent the pressing plate 5 from detaching from the threaded rod 16. A sliding groove 42 corresponding to the support rod 9 is arranged on the mesh cover 40. The flexible leakage net 6 can be a rope net. A support plate 17 is fixedly installed on the inner wall of the outer fixed cylinder 1. The bottom plate 4 is rotatably connected to the support plate 17. An outer baffle 110 is arranged at the open end of the outer fixed cylinder 1 at the gap between the mesh cover 40 and the outer fixed cylinder 1. One end of the support rod 9 is slidably installed with a connecting rod 10. A scraping plate 21 is fixedly installed on the connecting rod 10. The connecting rod 10 is rotatably connected to the support plate 17.

[0036] When performing waste treatment, first put solid waste into the hopper 2, and then the solid waste enters the inside of the screen cover 40 and is close to the bottom plate 4. At this time, the pressing plate 5 is located at the farthest end of the threaded rod 16 and is in close contact with the limiting plate 160. Then start the driving assembly 3 to drive the screen cover 40 to rotate. When rotating, the pressing plate 5 still stays at the position of the optical rod. As the screen cover 40 rotates freely, the screen cover 40 can facilitate the dispersion of waste during the rotation process. During this process, the waste can be initially dehydrated by the centrifugal force when the screen cover 40 rotates. The separated water and oil overflow from the meshes on the screen cover 40 and deposit at the bottom of the outer fixed cylinder 1. At the same time, due to the outwardly inclined shape of the screen cover 40, the waste will move along the screen cover 40. During the movement, the centrifugal radius gradually increases, making the centrifugal force gradually increase. When the waste completes the centrifugal dehydration operation and the waste is concentrated at the other end of the screen cover 40, at this time, start the driving assembly 3 to make the screen cover 40 rotate in the reverse direction. At this time, while the screen cover 40 rotates in the reverse direction, the pressing plate 5 will gradually move towards the bottom plate 4. During the movement, the waste is concentrated between the pressing plate 5 and the bottom plate 4. Finally, the waste is squeezed by the pressing plate 5, so that further dehydration operation can be carried out. After dehydration is completed, make the screen cover 40 rotate forward again, and the pressing plate 5 moves away from the bottom plate 4. When the screen cover 40 rotates, the compressed waste residue will be dispersed. At this time, discharging can be carried out at the other end of the screen cover 40. In addition, water and oil will be concentrated at the bottom of the outer fixed cylinder 1, so that they can be separately extracted and discharged.

[0037] When the pressing plate 5 moves towards and away from the bottom plate 4, the scraper 21 scrapes the surface of the outer fixed cylinder 1, which can prevent oil and water from adhering to the wall surface of the outer fixed cylinder 1, so that the water and oil can be fully collected.

[0038] By setting the screen cover 40 to be inclined outward, the waste can move in a direction away from the bottom plate 4. During the movement, the centrifugal force of the waste can be increased. By providing the threaded rod 16 and the pressing plate 5, the waste can be squeezed while the screen cover 40 rotates, so that residues, water and oil can be separated.

[0039] Please refer to Figure 1 、 Figure 2 As shown in [relevant figures], in one embodiment, it further includes a mounting base 11. A first telescopic member 12 is fixedly installed on the mounting base 11, and the output end of the first telescopic member 12 is connected to a sealing plate 15.

[0040] In this embodiment, by driving the movement of the sealing plate 15 through the first telescopic member 12, the collection of residues can be easily achieved after dehydration. When the dehydration is completed, the first telescopic member 12 is activated, and the sealing plate 15 will move away from the outer fixing cylinder 1. At this time, the residues in the mesh cover 40 will enter the aggregate tank 14 along the mesh cover 40.

[0041] Please refer to Figure 4 、 Figure 5 In one embodiment, a liquid discharge port 18 is provided at the bottom of the outer fixing cylinder 1, and a liquid collection tank 13 is fixedly installed at the bottom of the outer fixing cylinder 1. The liquid discharge port 18 is communicated with the liquid collection tank 13.

[0042] In this embodiment, both the liquid discharge port 18 and the liquid collection tank 13 are of a flat structure. By setting them in a flat structure, that is, minimizing the area of the upper liquid surface as much as possible, the deposition of oil on the liquid surface can be achieved, so as to facilitate the separate extraction of water and oil.

[0043] Please refer to Figure 8 、 Figure 9 and Figure 10 In one embodiment, a flexible tube 7 is slidably installed on the support rod 9, a flexible rod 8 is slidably installed in the flexible tube 7, one end of the flexible rod 8 away from the flexible tube 7 is slidably connected to another support rod 9, a spring 23 is connected between the flexible rod 8 and the flexible tube 7, the flexible filter net 6 is connected to the flexible rod 8 and the flexible tube 7, and both the flexible rod 8 and the flexible tube 7 are in contact connection with the inner wall of the mesh cover 40.

[0044] In this embodiment, in order to prevent waste from overflowing from the gap between the pressing plate 5 and the mesh cover 40 during the movement of the pressing plate 5, therefore, the flexible tube 7 and the flexible rod 8 are provided to fit the inner wall surface of the mesh cover 40, which can hold all the waste and can squeeze all the waste.

[0045] The flexible tube 7 has a certain hardness and a certain toughness and can be bent. The flexible tube 7 can be a metal bellows or a spring-type stainless steel bellows and can be bent in a bending plane. In the present invention, the bending direction of the flexible tube 7 is limited to the radial plane of the pressing plate 5. The flexible rod 8 also has a certain hardness and a certain toughness and can be bent. The flexible rod 8 can be a glass fiber rod. By adjusting various data in the production of the glass fiber rod, the hardness of the glass fiber rod can be controlled so that it has a certain supporting force.

[0046] Both the flexible tube 7 and the flexible rod 8 have a certain hardness and can be bent.

[0047] The connection mode of the flexible strainer 6 with the flexible rod 8 and the flexible tube 7 can be realized in the following form: the outer peripheral surface of the flexible strainer 6 is connected with the flexible tube 7 and the flexible rod 8. The connection mode between the outer peripheral surface of the flexible strainer 6 and the flexible tube 7 is a fixed connection, and the connection mode between the outer peripheral surface of the flexible strainer 6 and the flexible rod 8 is a sliding connection. That is, a number of sliding blocks are fixedly connected to the circumferential surface of the flexible strainer 6 at a certain interval. The connection mode between the outer peripheral surface of the flexible strainer 6 and the outermost end of the flexible rod 8 is a fixed connection, that is, at the position of the support rod 9. A chute corresponding to the sliding block is provided on the flexible rod 8. When the flexible rod 8 is retracted into the flexible tube 7, it will push the sliding block near the flexible rod 8 to move towards the other end of the flexible rod 8. Finally, due to the change of the inner diameter of the mesh cover 40, the flexible strainer 6 of the contracted part of the flexible rod 8 presents a wrinkled state.

[0048] Centrifugal dehydration is achieved by driving the rotation of the mesh cover 40. At this time, the rotation speed is much greater than that during the extrusion process. When rotating, the pressing plate 5 still stays at the position of the smooth rod and rotates freely with the mesh cover 40. During extrusion, the mesh cover 40 and the pressing plate 5 are driven to rotate in opposite directions. While the mesh cover 40 rotates in the opposite direction, the pressing plate 5 will gradually move towards the bottom plate 4. During the process of the pressing plate 5 moving and extruding, the flexible tube 7 and the flexible rod 8 contract or bend synchronously to adapt to the change of the inner diameter on the mesh cover 40. At this time, the flexible strainer 6 gradually presents a folded shape between the flexible tube 7 and the pressing plate 5. At the same time, the pressing plate 5 will rotate while extruding, that is, the materials on one side of the pressing plate 5 are turned up and down. When there are materials staying on the flexible strainer 6, through the continuous rotation of the pressing plate 5, the materials will fall from the flexible strainer 6 to the bottom. So on and so forth. The pressing plate 5 rotates while moving, which can prevent the materials from concentrating in the flexible strainer 6. Even if there are a small part of materials concentrated in the flexible strainer 6, it will not affect the extrusion dehydration. The extrusion dehydration operation can be completed by multiple cycles.

[0049] Please refer to Figure 11 and Figure 12 In one embodiment, a number of rod sleeves 29 are elastically and slidably installed on the pressing plate 5 in the circumferential direction. A support rod 28 is slidably installed in the rod sleeve 29. One end of the support rod 28 abuts against the mesh cover 40. A second spring 30 is connected between the support rod 28 and the rod sleeve 29.

[0050] In this embodiment, a number of mounting blocks 35 are fixedly installed on the pressing plate 5 in the circumferential direction. A third spring 34 is installed on the mounting block 35. The end of the third spring 34 away from the mounting block 35 is connected to the rod sleeve 29. The rod sleeve 29 is slidably installed on the pressing plate 5.

[0051] By sliding one end of the strut 28 inside the rod sleeve 29 and pressing the other end of the strut 28 against the mesh cover 40, the flexible sieve 6 can be supported during the movement of the pressing plate 5.

[0052] Please refer to Figure 8 、 Figure 9 and Figure 10 In one embodiment, a second telescopic member 22 is fixedly installed on the support rod 9, and the output end of the second telescopic member 22 is connected to a flexible tube 7 or a flexible rod 8.

[0053] In this embodiment, a receiving groove is formed on the support rod 9, the flexible tube 7 or the flexible rod 8 is slidably installed in the receiving groove, and the second telescopic member 22 is installed in the receiving groove. The second telescopic member 22 can be an electric telescopic rod or an elastic telescopic rod. When discharging, by starting the second telescopic member 22, the flexible rod 8 located at the bottom of the mesh cover 40 can be contracted into the flexible tube 7, so that the flexible tube 7 and the flexible rod 8 are away from the inner wall surface of the mesh cover 40, and the residue is discharged from the bottom of the mesh cover 40 and enters the aggregate tank 14.

[0054] As shown in the figure, there are two flexible sieves 6. When one flexible sieve 6 is tensioned, it presents a semi-circular ring. The connection mode between the support rods 9 and the flexible sieve 6 can be as follows: a plurality of sliding rods are slidably installed on the side wall of the receiving groove, the sliding rods are arranged at a certain interval, and the sliding block is fixedly connected to one end of the flexible sieve 6. When the support rod 9 slides towards the bottom plate 4 and the flexible rod 8 or the flexible tube 7 approaches the pressing plate 5, the sliding rod will be pushed to move, so as to realize the synchronous contraction of the flexible sieve 6.

[0055] When the pressing plate 5 returns to the initial position, under the action of the elastic restoring force of the elastic telescopic rod and the restoring force of the spring 23, the flexible rod 8 is in contact with the inner wall of the mesh cover 40 again, and the flexible sieve 6 is tensioned.

[0056] Please refer to Figure 4 、 Figure 5 、 Figure 13 and Figure 14 In one embodiment, a feeding cover 20 is fixedly installed in the outer fixed cylinder 1. The feeding cover 20 is communicated with the feeding hopper 2, the feeding cover 20 is in contact with the mesh cover 40, and a rotating plate 41 is rotatably installed on the mesh cover 40.

[0057] In this embodiment, a fixing seat 19 is fixedly installed inside the outer fixing cylinder 1. An inlet cover 20 is fixedly installed on the fixing seat 19. The lower end surface of the inlet cover 20 is in close contact with the mesh cover 40. There is a certain gap between the upper end surface of the inlet cover 20 and the inner wall of the outer fixing cover for giving way to the connecting rod 10 and the scraping plate 21. A rotating plate 41 is rotatably installed at a position corresponding to the inlet cover 20 on the mesh cover 40. There are two symmetrically arranged rotating plates 41. The rotating plates 41 are elastically installed. When not under force, the two side rotating plates 41 close together. When under force, the rotating plates 41 rotate towards the inside of the mesh cover 40.

[0058] Please refer to Figure 4 、 Figure 5 、 Figure 13 and Figure 14 In one embodiment, an arc-shaped filter plate 25 is detachably installed on the feed hopper 2. The arc-shaped filter plate 25 is an electromagnet.

[0059] In this embodiment, the highest point of the arc-shaped filter plate 25 is located in the middle. The feed hopper 2 is in the shape of an inverted funnel. When the waste enters from the feed hopper 2, it first contacts the top of the arc-shaped filter plate 25, that is, the highest point. At this time, if there is metal waste, the metal waste will stay at the highest point position of the arc-shaped filter plate 25, while the waste will fall to the inlet cover 20 in the middle or at both ends of the arc-shaped filter plate 25 and finally enter the mesh cover 40.

[0060] By providing an electromagnet, the metal waste can be sorted. In addition, by setting the filter plate in an arc shape, the metal waste and the organic waste can be separated. Secondly, by setting the electromagnet in the form of a filter plate, the magnetic force can cover the filter plate, which can prevent the metal waste from squeezing the mesh cover 40.

[0061] One side surface of the arc-shaped filter plate 25 is on the same curved surface as the outer fixing cylinder 1. Therefore, when the scraping plate 21 cleans the surface of the outer fixing cylinder 1, it can also clean one side surface of the arc-shaped filter plate 25 at the same time, thereby avoiding the situation of blockage of the arc-shaped filter plate 25.

[0062] Please refer to Figure 4 、 Figure 5 、 Figure 13 and Figure 14 In one embodiment, rotating shafts 26 are rotatably installed at positions on both sides of the arc-shaped filter plate 25 on the feed hopper 2. Blades 27 are fixedly installed on the rotating shafts 26.

[0063] In this embodiment, a power assembly 24 is installed on the feed hopper 2. The power assembly 24 is used to drive the two side rotating shafts 26 to rotate simultaneously. The power assembly 24 includes a second motor 241, a pulley 242, and a belt 243. The output end of the second motor 241 is connected to the pulley 242 and the rotating shaft 26, and the pulleys 242 on the two side rotating shafts 26 are driven by the belt 243.

[0064] When the volume of the waste object is relatively large, it cannot enter the feed cover 20 from the exact middle of the arc-shaped filter plate 25. Therefore, it will roll into both ends of the arc-shaped filter plate 25. Therefore, by providing the rotating shaft 26 and the blade 27, the waste at both ends of the arc-shaped filter plate 25 can be preliminarily crushed.

[0065] For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic characteristics of the present invention, the present invention can be implemented in other specific forms.
