Technical Field

[0001] The utility model relates to the technical field of solid material processing, in particular to solid material screening equipment. Background Art

[0002] Recycled waste materials mainly include discarded items that can be reprocessed or recycled, such as scrap metals, etc. These materials can be converted into new raw materials or products after appropriate treatment and processing.

[0003] In the recycling process of recycled waste materials, the processing of solid materials and the sorting of metals are crucial links. Currently, these waste materials are usually transported in bagged form, and the solid materials need to be poured out of the bags before screening. However, the current operation method generally involves manually cutting the bags and then pouring them out. The process is inefficient, cumbersome, time-consuming and labor-intensive.

[0004] Therefore, a solid material screening device is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a solid material screening device. Through the cooperation of the curved hook and the sharp edge on the circular ring piece, when the bagged solid material passes through, the solid material slides downward to give a rotational force to the turn plate, driving the turn plate and the circular ring piece to rotate, cutting the bag, and the curved hook hooks the bag, so that the solid material scatters from the damaged part of the bag and then detaches from the bag, thereby achieving the purpose of separating the solid material from the bag, and no manual operation is required, thereby improving convenience.

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

[0007] A solid material screening device, comprising:

[0008] A separation box is provided with a feed channel, and the feed channel is arranged to be inclined downward. A discharge port is provided at the lower end of the separation box, and the lower end of the separation box is funnel-shaped.

[0011] Preferably, a plurality of scrapers are provided on the side wall of the separation box, and each of the scrapers is provided with a plurality of grooves, and the grooves cooperate with corresponding annular sheets and blades.

[0012] Preferably, each of the scrapers is vertically arranged directly below the rotating shaft.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The solid material screening equipment described in the utility model cooperates with the curved hook and the sharp edge on the circular ring piece. When the bagged solid material passes through, the solid material slides downward to exert a rotational force on the rotating plate, driving the rotating plate and the circular ring piece to rotate, cutting the bag, and the curved hook hooks the bag, so that the solid material scatters from the damaged part of the bag and then separates from the bag, thereby achieving the purpose of separating the solid material from the bag, and no manual operation is required, thereby improving convenience.

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] See also Figures 1 to 5 , the utility model provides a solid material screening equipment, the technical solution is as follows:

[0025] A separation box 1 is provided with a feed channel 2, and the feed channel 2 is arranged to be inclined downward. A discharge port 3 is provided at the lower end of the separation box 1, and the lower end of the separation box 1 is funnel-shaped. A conveyor belt 4 is provided below the discharge port 3, and a screening unit is connected to the end of the conveyor belt 4. A plurality of rotating shafts 5 are provided on the inner side wall of the separation box 1, and a plurality of rotating plates 6 are rotatably installed on each rotating shaft 5, and the rotating plate 6 is a rotating body of an integrated structure. A circular ring piece 7 is provided on the circumference of the side wall of each rotating plate 6, and a plurality of curved hooks 701 are evenly provided on the circumference of each circular ring piece 7, and a sharp edge 702 is provided on the outer side of each curved hook 701, and a plurality of rotating shafts 5 are arranged in pairs in parallel at the end edge of the feed channel 2.

[0026] The staff puts the bagged solid material into the feed channel 2, and the solid material enters the separation box 1 through the feed channel 2. After passing through the feed channel 2, the solid material contacts the annular sheet 7. The sharp edge 702 on the annular sheet 7 cuts the bag outside the solid material to perform bag breaking. The hook 701 on the rotating plate 6 is used to hook the bag. At the same time, the solid material also provides rotational power for the bag breaking device. The rotating action can prevent the solid material from being blocked on the rotating plate 6 and can also reduce the probability of some solid material adhering to the rotating plate 6. During operation, when the solid material passes through the annular sheet 7, the bag will be cut, and the hook 701 on the rotating plate 6 will hook the bag. The solid material will scatter from the damaged part of the bag, and then separate from the bag, and fall from the discharge port 3 onto the conveyor belt 4, and then be transported to the screening unit via the conveyor belt 4 for screening and sorting. During the process, people can be arranged around the conveyor belt 4 to sort out the bags; multiple rotating shafts 5 are arranged in parallel in pairs, so that the solid material falls between the two rotating shafts 5, which can increase the bag breaking effect and ensure the working quality of the equipment.

[0027] Each rotating shaft 5 is provided with a plurality of blades 8, each blade 8 is located between two adjacent rotating plates 6, and each blade 8 and the rotating plate 6 rotate independently; adding blades 8 between the rotating plates 6 can further ensure that the bags are cut smoothly, and also improve the bag breaking effect, so that the entire structure can adapt to more working conditions; the rotating parts can reduce the chance of garbage accumulation on the parts, so the added blades 8 also adopt a free rotation working mode. When each blade 8 is subjected to different friction from the bag, each blade 8 can rotate in different states respectively, thereby improving the bag breaking efficiency.

[0028] The cutting edge of each blade 8 is located between the root of the hook 701 and the outer side of the hook 701, and the mass range of the blade 8 is 1.5-2 times the mass of the turn plate 6; the rotation speed of the blade 8 needs to be different from the turn plate 6, and considering that the rotational power of the blade 8 is provided by the friction force generated by the bag when it falls, the bag hooks the annular piece 7, and the rotation speed of the turn plate 6 is equal to or less than the falling speed of the bag, the rotation speed of the blade 8 should be slower than the turn plate 6 to increase the effect of the blade 8 in cutting the bag. Therefore, the mass of the blade 8 is set to 1.5-2 times the mass of the turn plate 6, which makes the blade 8 more difficult to rotate than the turn plate 6, but can ensure that the blade 8 can rotate, thereby improving the efficiency of breaking the bag.

[0029] A plurality of scrapers 9 are provided on the side wall of the separation box 1, and each scraper 9 is provided with a plurality of grooves 10, and the grooves 10 cooperate with the corresponding annular pieces 7 and blades 8; the hooks 701 of the rotating plate 6 installed in the same rotating shaft 5 are in the same direction, but the working environment is complex. Considering that there may be bag fragments hooked on the hooks 701, scrapers 9 are set within the rotation range of the rotating plate 6 and the blade 8 to clean up the bag fragments stuck on the hooks 701 and the blades 8; at the same time, the setting of the scraper 9 can also maintain the overall cleanliness of the rotating plate 6 and the blade 8, reducing the chance of bags and material fragments getting stuck on them.

[0030] Each scraper 9 is arranged vertically just below the rotating shaft 5; setting the scraper 9 vertically just below the rotating shaft 5 can ensure the scraping effect. When the solid material rotates to the lowest point with the annular piece 7 and the blade 8, it is easiest to scrape the bag by setting the scraper 9 here, thereby improving the stability of the operation of the annular piece 7 and the blade 8.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
