[0003] At present, there is an existing raw material silica processing device in a new processing technology of metallic silicon (such as patent number: CN218048120U), which discloses a raw material silica processing device in a new processing technology of metallic silicon, including a crushing box, a disassembly structure and a filter screen, the bottom ends of both sides of the crushing box are fixed with supporting feet, the two sides inside the crushing box are provided with disassembly structures, the inner wall of the crushing box is provided with a noise reduction structure, and the top of the crushing box is provided with a splash-proof structure. The utility model pulls multiple sets of pull rods, and then the pull rod drives the plug block to compress the telescopic spring to leave the slot, and then pulls the filter screen to slide out of the mounting seat to clean and collect the large-sized silica remaining on it for a new round of crushing, while preventing the pores of the filter screen from being blocked, inserting the cleaned filter screen into the mounting seat and moving it to the original position, and then loosening the pull rod, so that the telescopic spring rebounds and pushes the mounting seat into the slot to fix the filter screen, thereby realizing the rapid disassembly function of the device, improving the convenience of the device, facilitating the rapid disassembly of the filter screen, and ensuring the filtering effect of the filter screen.

[0004] However, during the implementation of the above technical solution, it was found that there were at least the following problems: in the process of cleaning the materials accumulated on the surface of the filter, the staff needed to open the side door, and the staff needed to lift the filter and the filter material out of the device together, and install the filter again after cleaning. The height of the filter and the weight of both the filter and the filter material made it difficult for the staff to clean and collect, which increased the time for cleaning and collecting. The increase in cleaning and collecting time increased the downtime of the device, thereby reducing the crushing efficiency. Utility Model Content

The overall idea is as follows:

[0029] By setting the filter screen 3 and cooperating with the filter frame 10, after working for a period of time, no more material is poured into the crushing box 2. At this time, the fixing screw 8 is rotated so that the fixing screw 8 is no longer tightly fitted with the limit plate 9. At this time, the limit plate 9 loses its restriction. At this time, the limit plate 9 slides downward, and the filter screen 3 is rotated downward to make the material on the filter screen 3 slide downward first. At this time, the material falls into the filter frame 10. At this time, the limit plate 9 is rotated so that the limit plate 9 drives the filter screen 3 on the rotating shaft 4 to reset. At this time, the limit plate 9 is inserted into the inside of the fixing groove 6. At this time, the fixing screw 8 is rotated so that the fixing screw 8 is tightly fitted with the limit plate 9 to fix the limit plate 9. At this time, the crushing box 2 is normally Working, at this time, the threaded sleeve 13 is rotated to release the connection between the threaded sleeve 13 and the threaded rod 11, and the fixing block 12 is rotated so that the fixing block 12 is no longer fitted with the filter frame 10. At this time, the filter frame 10 is pulled out to pour out the material in the filter frame 10. In the process of cleaning and collecting the material accumulated on the filter screen 3, the mechanism fixing the filter screen 3 is released so that the material in the filter screen 3 falls downward into the filter frame 10. The filter frame 10 is located at the bottom of the device, which is convenient for the staff to pour the material out of the device, and the difficulty of cleaning and collecting the material is reduced, thereby reducing the cleaning and collection work time, reducing the downtime of the device, and avoiding affecting the crushing efficiency.

[0030] The filter 3 is provided with a mounting groove 14 on the outside, and the rotating shaft 4 is slidably connected to the inside of the mounting groove 14 to facilitate the connection between the rotating shaft 4 and the filter 3. A limiting block 15 is fixedly installed inside the mounting groove 14, and a limiting groove 16 is provided on the outside of the rotating shaft 4. The limiting block 15 is slidably connected to the inside of the limiting groove 16 to prevent the filter 3 from rotating outside the rotating shaft 4. A sliding groove 17 is provided inside the limiting groove 16, and the limiting plate 9 is slidably connected to the inside of the sliding groove 17 to facilitate the release of the connection between the limiting plate 9 and the rotating shaft 4. The limiting plate 9 is externally threadedly connected to a limiting screw 18, and the limiting screw 18 is located below the fixing screw 8 to prevent the limiting plate 9 from being in contact with the rotating shaft 4 during the rotation of the filter 3. The connection is released by setting the mounting groove 14 and cooperating with the limit screw 18. When the work is completed, the fixing screw 8 is rotated so that the fixing screw 8 is no longer tightly fitted with the limit plate 9. At this time, the limit plate 9 loses its restriction and the limit plate 9 slides downward. At this time, the limit screw 18 is rotated to release the connection between the limit screw 18 and the limit plate 9. At this time, the limit plate 9 is pulled to release the connection between the limit plate 9 and the slide groove 17. At this time, one end of the rotating shaft 4 is pulled to release the connection between the rotating shaft 4 and the filter screen 3. At this time, the filter screen 3 slides downward and slides out from the discharge port of the crushing box 2. At this time, the filter screen 3 can be cleaned. At the same time, different filter screens 3 can be selected according to different filtering requirements to improve the applicability of the equipment.

[0031] A handle 19 is fixedly mounted on the outside of the filter frame 10 . The handle 19 is a concave body, which makes it easy to pull the handle 19 .

[0032] Working principle:

[0033] The first step is to set the filter screen 3 and cooperate with the filter frame 10. After working for a period of time, the material is no longer poured into the crushing box 2. At this time, the fixing screw 8 is rotated so that the fixing screw 8 is no longer tightly fitted with the limit plate 9. At this time, the limit plate 9 loses its restriction. At this time, the limit plate 9 slides downward, and the filter screen 3 is rotated downward to make the material on the filter screen 3 slide downward first. At this time, the material falls into the filter frame 10. At this time, the limit plate 9 is rotated to make the limit plate 9 drive the filter screen 3 on the rotating shaft 4 to reset. At this time, the limit plate 9 is inserted into the inside of the fixing groove 6. At this time, the fixing screw 8 is rotated to make the fixing screw 8 fit tightly with the limit plate 9 to fix the limit plate 9. At this time, the crushing box 2 performs normal work. At this time, the threaded sleeve 13 is rotated to release the connection between the threaded sleeve 13 and the threaded rod 11. At this time, the fixing block 12 is rotated so that the fixing block 12 is no longer fitted with the filter frame 10. At this time, the filter frame 10 is pulled out to pour out the material in the filter frame 10;

[0034] In the second step, by setting the installation groove 14 and cooperating with the limit screw 18, when the work is completed, the fixing screw 8 is rotated so that the fixing screw 8 is no longer tightly fitted with the limit plate 9, and the limit plate 9 loses its restriction. At this time, the limit plate 9 slides downward, and the limit screw 18 is rotated to release the connection between the limit screw 18 and the limit plate 9. At this time, the limit plate 9 is pulled to release the connection between the limit plate 9 and the slide groove 17. At this time, one end of the rotating shaft 4 is pulled to release the connection between the rotating shaft 4 and the filter 3. At this time, the filter 3 slides downward and slides out from the discharge port of the crushing box 2. At this time, the filter 3 can be cleaned.

[0035] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
