Description

Technical Field

[0001] This utility model relates to the field of waste treatment, and in particular to a large solid waste treatment line. Background Technology

[0002] With the increasing urbanization, a large amount of solid waste is generated, with bulky solid waste, such as construction waste and renovation waste, being a significant type. Previously, bulky solid waste was simply piled up, occupying a large amount of land. Therefore, a process has emerged to break bulky solid waste into smaller pieces, lightweight materials, dust, metals, and film materials, which are then transported to a sorting workshop for further processing. However, this method has several drawbacks: First, the crushing site generates a lot of dust, and the crushed material is prone to dust generation during subsequent sorting, affecting the health and safety of workers. Second, the variety of crushed materials (such as metals and film materials) affects the efficiency of subsequent sorting operations. Furthermore, the mixed composition of the crushed material makes transportation inconvenient and increases processing costs. Utility Model Content

[0018] This large solid waste processing line crushes large pieces of waste and sorts out the metal materials. The dust removal unit 6 classifies and recycles lightweight materials, dust, and film materials. Simultaneously, the dust removal unit 6 connects to the dust removal pipes of each work unit after crushing, enabling centralized dust removal. Its beneficial effects are: First, the processing line has a fully covered dust removal unit 6, which achieves centralized dust removal, ensuring a clean workshop environment. Furthermore, in subsequent sorting sections, because there is no dust in the mixed material, there is no dust generation, effectively ensuring the health and safety of workers. Second, the processing line recovers metal, lightweight, dust, and film materials from the crushed material. Metal materials can be directly sent to the scrap steel processing station, and film materials go to the plastic recycling station, achieving rapid resource recycling. Third, the pre-sorted mixed material has high purity, with no metal or film materials affecting the operation, greatly improving sorting efficiency. Fourth, the high purity of the mixed material allows for direct baling and transportation via a baler, facilitating subsequent transport and significantly reducing processing costs.

[0019] Furthermore, the magnetic separator 4 includes a magnetic separation chamber 41 and a magnetic separation module 40 disposed in the magnetic separation chamber 41.

The powerful magnet 400 is close to the inner end of the annular conveyor belt 401, and the outer end of the annular conveyor belt 401 is located directly above the metal discharge port 43. The two ends of the annular conveyor belt 401 wrap around a passive roller 403 and a drive roller 404. The drive roller 404 is directly connected to the drive motor 402 or connected to the drive motor 402 through a belt drive system. The passive roller 403 and the drive roller 404 are fixedly connected to a side plate frame 405, and the side plate frame 405 is fixedly connected to the magnetic separator chamber 41. The advantages are: the magnetic separator 4 with this configuration has a simple structure, occupies little space, is easy to arrange, and achieves good metal separation.

[0020] Furthermore, the feeding chain conveyor 2 is equipped with first protective baffles 23 at both ends, and a protective staircase 25 is provided on the outside of the feeding chain conveyor 2. The twin-shaft crusher 1 is equipped with a platform 24 on the right end, and the protective staircase 25 connects to the platform 24 on the right side; the discharge belt conveyor 3 is equipped with second protective baffles 30 at both ends. The beneficial effect is that this setting can achieve safe operation and prevent material from being thrown into the external space.

[0021] Furthermore, the discharge port 100 of the crushing host 10 is the large material outlet 13; its beneficial effect is that the structure is simple and the overall production line height is small.

[0022] Furthermore, it also includes a bulk material primary sorting machine 7, which includes a three-dimensional frame 70. The feed inlet 100 of the crushing host 10 is connected to the mixing inlet 701 at the upper end of one side of the three-dimensional frame 70. A vibrating feeder is installed at the lower end of the mixing inlet 701. The light material outlet directly above the three-dimensional frame 70 is connected to the fourth dust removal branch pipe 71. The fourth dust removal branch pipe 71 is connected to the lower left end of the dust removal main pipe 61. The heavy material outlet 13 is located directly below the three-dimensional frame 70. An air inlet 702 connected to a blower is provided on the lower side of one end of the three-dimensional frame 70. Its beneficial effect is that this setting can further separate light film material and dust from below, effectively avoiding the film material and dust mixed by heavy materials and other materials, and further purifying the material.

[0023] Furthermore, the three-dimensional frame 70 includes a rectangular three-dimensional steel frame, with four wall panels 72 fixedly connected to the four sides of the steel frame. A set of opposing wall panels 72 are connected to two opposing buffer bases 73 via a second threaded component 79. A reciprocating curved cavity is formed between the two buffer bases 73. Several rectangular plates 741 of the flow channel plate 74 are fixedly attached to the inner side of the buffer bases 73, forming a reciprocating curved air separation channel. A wear-resistant protective plate 75 is fixed to the outer wall of the plates 741, and an elastic rubber pad 76 is provided between them. Preferably, the inner side of the buffer base 73 is provided with vertically spaced triangular blocks 731, and triangular grooves 732 are formed between adjacent triangular blocks 731. The triangular grooves 732 and triangular blocks 731 of one buffer base 73 are respectively aligned with the triangular blocks 731 and triangular grooves 732 of another buffer base 73, forming a reciprocating curved cavity. Its beneficial effects are as follows: First, the integral buffer base 73 can quickly and uniformly distribute the large local inertial load of the material into a smaller, evenly distributed load before transmitting it to the three-dimensional frame 70. Simultaneously, wear-resistant protective plates 75 and elastic pads 76 protect the partition plate 741, greatly improving equipment stability. The partition plate 741 is durable and can be used for a long time without replacement, significantly reducing operating costs. Second, the flow channel plate 74 and protective plate 75 are both separate units; only the damaged part of the partition plate 741 needs to be replaced, reducing spare parts costs and size, greatly simplifying replacement and maintenance. Third, the integral buffer base 73 increases the deformation of the bent wall plate. When there is a risk of tower blockage in the cavity, subsequent feeding squeezes the lower end material, enlarging the cavity opening and automatically clearing blockages. Frequent manual clearing is unnecessary, resulting in a longer stable operating time and higher efficiency.

[0024] One of the wall panels 72 has a horizontal mixing inlet 701 at the upper end and an air inlet 702 at the lower end; the two buffer bases 73 form a light material outlet at the upper end and a heavy material outlet at the lower end, with the upper opening 733 of one of the buffer bases 73 facing the mixing inlet 701 and its lower opening 734 facing the air inlet 702.

[0025] Furthermore, the inner surface of the buffer base 73 is provided with multiple large-sized positioning grooves 730 at equal vertical intervals, and the wall plate 72 is provided with transverse connecting blocks 721 at equal vertical intervals. The positioning grooves 730 are elastically interference-fitted with the connecting blocks 721. The connecting blocks 721 are rectangular blocks or dovetail blocks, and the positioning grooves 730 are rectangular grooves or dovetail grooves. The wall plate 72 and the connecting blocks 721 are fixedly connected or welded together by threaded parts. The beneficial effects are: this arrangement has high connection accuracy and high overall structural strength.

[0026] Furthermore, the buffer base 73 is an integral injection-molded block, and its positioning groove 730, triangular stop 731, triangular groove 732, upper opening 733, and lower opening 734 are all formed during injection molding. The buffer base 73 can be any one of a rubber block, a nylon block, and a polyurethane block. Furthermore, the outline dimensions of each sub-plate 741 are the same as the outline dimensions of the upper and lower sides of the triangular stop 731. A rectangular rubber plate-shaped elastic pad 76 is attached to the outer side of each sub-plate 41. The protective plate 75 can be any one of high manganese steel ZGMn13, wear-resistant cast iron Cr15Mo3, and metal / ceramic composite plate. Its beneficial effect is that the protective plate 75 and the elastic pad 76 can effectively protect the sub-plate 741 and improve the utilization efficiency of the sub-plate 741.

[0027] The positioning groove 730 is an isosceles triangular groove, and the triangular stop 731 is an equiangular triangular protrusion; or the apex angle of the triangular stop 731 is 45°-75°. Its beneficial effect is that this design provides excellent material guiding performance.

[0028] Furthermore, a set of opposing wall panels 72 has multiple rows and columns of transverse first through holes, and the buffer base 73 has transverse connecting holes with a blind hole structure inside. A large-diameter fixing groove is formed at the end of the transverse connecting holes. A nested nut 77 is integrally injection molded to connect to the fixing groove. A first threaded component 78 passes through the first through holes and the transverse connecting holes to connect to the nested nut 77. Alternatively, the nested nut 77 has a toothed structure on its front and rear walls, and the toothed structure is integrally injection molded to connect to the fixing groove; the first threaded component 78 is an internal hexagonal head screw or an external hexagonal head bolt. Preferably, the wall panel 72 has multiple rows and columns of transverse second through holes, and a second threaded component 79 passes through the through holes of the protective plate 75, the elastic pad 76, the dividing plate 741, the oblique through holes of the buffer base 73, and the second through holes to connect to the nut. The advantages are: this arrangement facilitates installation and provides high connection strength.

[0029] The above descriptions are merely some embodiments of this utility model.
