Description

Technical Field

[0001] This utility model relates to the field of waste solar panel recycling technology, and more specifically, it relates to a multi-stage separation device for clean energy equipment. Background Technology

[0002] In the multi-stage separation process for recycling waste solar panels, the conveyor is a key piece of equipment for continuous material transport. However, existing conveyors suffer from significant electrostatic adsorption at the discharge end, severely impacting sorting efficiency and recovery rate.

[0003] Specifically, when crushed solar panel material passes through the conveyor belt, static electricity accumulates due to continuous friction between the material and the belt. This electrostatic effect leads to two main problems: first, electrostatic adsorption significantly reduces metal recovery rates, especially for smaller particles of valuable metals such as copper and aluminum, resulting in severe loss; second, the adsorbed mixed debris continuously accumulates on the belt surface, not only wasting resources but also accelerating belt wear. The electrostatic effect is particularly pronounced in dry environments.

[0004] Therefore, a multi-stage separation device for clean energy equipment is proposed to solve the above problems. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-stage separation device for clean energy equipment that improves material recycling efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A multi-stage separation device for clean energy equipment includes a crusher, a conveyor with an inlet and an outlet, the inlet of the conveyor being located near the crusher, a baffle assembly on the outlet side of the conveyor, a first air separator below the baffle assembly, two sets of flow guiding mechanisms symmetrically arranged along the center line of the conveyor below the outlet of the conveyor, and a second air separator on the side of the first air separator away from the conveyor; the baffle assembly has a first base plate, a second base plate on the side of the first base plate away from the conveyor, and an outlet is formed through the top of the first base plate and the second base plate.

[0008] The present invention is further configured such that: the conveyor has a belt, the surface of the belt has multiple sets of conveying rubber strips, a set of side brackets is provided on both sides of the belt, and an installation shaft is provided below the side brackets.

[0009] The present invention is further configured such that: the top of the second base plate has a slope, and the side of the slope near one end of the first base plate is lower than the other end of the slope.

[0010] By adopting the above technical solution and using a second bottom plate with a slope, the ability of mixed debris to flow downward is improved, and the accumulation of mixed debris is avoided.

[0011] The present invention is further configured such that: the flow guiding mechanism has a bearing, the bearing has an inner shaft and an outer shaft, the inner shaft of the bearing is fixedly connected to the mounting shaft, and the outer shaft of the bearing is provided with multiple sets of scrapers, the scrapers being inclined to the center of the bearing shaft.

[0012] The present invention is further configured such that: a damper is installed on the side bracket near the bearing, the axis of the damper is parallel to the scraper, the damper has a damping shell and a damping block, a spring is provided inside the damping shell, the spring is connected to the damping block, and the damping block has two serrated protrusions.

[0013] By adopting the above technical solution, the damper, bearing, and scraper work together to remove the mixed debris adsorbed on the belt below the eddy current separator, thereby improving the equipment's recovery rate and avoiding equipment wear problems.

[0014] Another embodiment of this utility model is configured such that: two sets of third base plates are provided on the side of the second base plate near the conveyor, and the two sets of third base plates are provided on both ends of the discharge port.

[0032] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0033] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.

[0034] Example 1, please refer to Figure 1-8 The present invention provides the following technical solution:

[0035] Specifically, it refers to a multi-stage separation device for clean energy equipment, see [link / reference]. Figure 1-3The system includes a crusher 1, which crushes waste solar panels (after physically removing the battery box and frame) into mixed debris. A conveyor 2 is installed on one side of the crusher 1 to transport the mixed debris upwards. The conveyor 2 has an inlet and an outlet. The mixed debris is transported upwards via the conveyor 2. The inlet of the conveyor 2 is located near the crusher 1. A baffle assembly 3 is installed on one side of the outlet of the conveyor 2 to guide the mixed debris. A first air separator 5 is installed below the baffle assembly 3 to separate glass fragments from the mixed debris. The first air separator 5 is located near the conveyor 2. Two sets of flow guiding mechanisms 4 are provided below the discharge end of the conveyor 2. The flow guiding mechanisms 4 are used to scrape the mixed debris attracted by electrostatics on the conveyor belt from below the conveyor 2, so as to avoid the debris from being attached to the conveyor 2 for a long time due to electrostatic attraction and causing residue, which would affect the operation of the equipment. On the other hand, scraping off the magnetic debris remaining on the conveyor 2 can avoid the waste of mixed debris and improve the recycling rate of waste solar panels. The two sets of flow guiding mechanisms 4 are symmetrically arranged along the center line of the conveyor 2. The first air separation unit 5 is located on the side away from the conveyor 2. The second air separation unit 6 is used to separate various single-element materials in the mixed debris, such as copper, silicon, plastics, etc.

[0036] See Figure 2-5 The conveyor 2 has a belt with multiple sets of conveying rubber strips 21 on its surface. A set of side supports 22 is provided on each side of the belt, and a mounting shaft 23 is located below each side support 22. The guard assembly 3 has a first base plate 31, and a second base plate 32 is provided on the side of the first base plate 31 away from the conveyor 2. The top of the second base plate 32 has a slope. The side of the slope closest to the first base plate 31 is lower than the other side of the slope. A discharge port 33 is formed through the tops of the first base plate 31 and the second base plate 32.

[0037] Specifically, when the conveyor 2 transports the mixed debris to the guard assembly 3, it will enter the guard assembly 3 due to the inertia of the conveyor 2. The second bottom plate 32 catches the mixed debris that falls after impacting the guard assembly 3 and guides the mixed debris towards the discharge port 33, thereby improving the ability of the mixed debris to flow downward and preventing the mixed debris from accumulating.

[0038] Example 2, see Figure 8 Some of the mixed debris will splash onto both sides of the discharge port 33 after impacting the guard assembly 3. Two sets of third base plates 34 are provided on the side of the second base plate 32 near the conveyor 2. The two sets of third base plates 34 are located on both ends of the discharge port 33. The mixed debris is guided to the discharge port 33 through the third base plates 34, so that the mixed debris splashed on both sides flows to the discharge port 33, further improving the ability of the mixed debris to flow to the discharge port 33 and avoiding the accumulation of mixed debris on both sides.

[0039] See Figure 5-7The flow guiding mechanism 4 has a bearing 41, which has an inner shaft and an outer shaft. The inner shaft of the bearing 41 is fixedly connected to the mounting shaft 23. The outer shaft of the bearing 41 is provided with multiple sets of scrapers 42, which are inclined to the axis of the bearing 41. A damper 43 is installed on the side bracket 22 near the bearing 41, and the axis of the damper 43 is parallel to the scrapers 42. The damper 43 has a damping housing 431 and a damping block 432. A spring is inside the damping housing 431, and the spring is connected to the damping block 432. The damping block 432 has two serrated protrusions.

[0040] Specifically, the two serrated protrusions can hold the scraper 42 in place when it is not driven by the conveyor strip 21, thus allowing the mixed debris adsorbed on the belt to be scraped off by the scraper 42, preventing loss due to the electrostatic adsorption of mixed debris by the conveyor belt of the conveyor 2. When the conveyor strip 21 drives the scraper 42, which is originally on one side of the conveyor belt of the conveyor 2, the conveyor strip 21 abuts against the scraper 42 and makes it tend to move downward. However, the scraper 42 is restricted by the bearing 41 and can only rotate around the axis of the bearing 41. The scraper 42, which was originally held by the damping block 432, rotates upward due to the rotational tendency until the conveyor strip 21 has completely passed the scraper 42. The damping block 432 then holds the next scraper 42, thus achieving the scraping of mixed debris on the conveyor belt of the conveyor 2 without external drive, improving the utilization rate of mixed debris.

[0041] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
