[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: a filter device that is easy to clean internally, including an outer cylinder 1, a filter screen 5 inside the outer cylinder 1, an inlet 2 welded to the top of the outer cylinder 1, an outlet 3 welded to the bottom of the outer cylinder 1, and a collection box 4 on one side of the outer cylinder 1.

[0023] A fan 404 is installed on one side of the collection box 4 by screws. A corrugated pipe 403 is inserted into the top of the collection box 4. A connecting block 407 is connected to one side of the corrugated pipe 403 by threads. A slider 406 is welded to the outer wall of the connecting block 407. A sliding groove 405 is attached to the outer wall of the slider 406. A cover plate 401 is provided on the other side of the sliding groove 405. A threaded rod 402 is threadedly connected to the inside of the cover plate 401.

[0024] A cleaning brush 507 is attached to the inside of the filter screen 5. An internal frame 506 is inserted into one side of the cleaning brush 507. A connecting shaft 509 is inserted into one side of the internal frame 506. A third bevel gear 501 is inserted into one side of the connecting shaft 509. A first bevel gear 503 meshes with one side of the third bevel gear 501. A second bevel gear 502 meshes above the first bevel gear 503. A rotating shaft 508 is inserted inside the second bevel gear 502. A motor 504 is inserted below the first bevel gear 503. One side of the connecting shaft 509 passes through a fixing ring 505.

[0025] In this embodiment, as Figure 1 and Figure 4 As shown, the first bevel gear 503 forms a rotating structure through the motor 504, and the second bevel gear 502 forms a rotating structure through the first bevel gear 503. The rotating shaft 508 also forms a rotating structure through the second bevel gear 502. This eliminates the need for frequent manual disassembly and cleaning of the filter screen 5, saving time and labor costs and ensuring continuous and stable operation of the filtration device. The motor 504 causes the first bevel gear 503 to rotate clockwise, and the first bevel gear 503 meshes with the second bevel gear 502. The second bevel gear 502 drives the rotating shaft 508 to rotate, which in turn drives the internal frame 506 to rotate. The internal frame 506 causes the cleaning brush 507 to rotate, thus cleaning the inside of the filter screen 5. The clockwise rotation facilitates cleaning.

[0026] In this embodiment, as Figure 1 and Figure 4 As shown, the external structural dimensions of the rotating shaft 508 are consistent with the internal structural dimensions of the connecting shaft 509. The connecting shaft 509 forms a rotating structure through the third bevel gear 501, and the filter screen 5 also forms a rotating structure through the connecting shaft 509. The first bevel gear 503 causes the third bevel gear 501 to rotate, and the third bevel gear 501 causes the connecting shaft 509 to rotate. The connecting shaft 509 rotates counterclockwise, driving the filter screen 5 to rotate, achieving one clockwise rotation and one counterclockwise rotation. This facilitates cleaning the filter screen 5, maintains the good filtration effect of the filter screen 5, and avoids the decline in filtration performance due to clogging of the filter screen 5. The automatic cleaning function can effectively reduce malfunctions or downtime caused by clogging of the filter screen 5, and improve the reliability of the entire system.

[0027] In this embodiment, as Figure 1 and Figure 2 As shown, the outer cylinder 1 and the inlet 2 are connected as a single unit, and the outlet 3 and the outer cylinder 1 are also connected as a single unit. The items to be filtered are poured into the inlet 2 and filtered through the internal filter screen 5, so that they can be discharged from the bottom of the outlet 3. Since the inlet 2 and the outlet 3 are directly connected, the feeding and filtering can be done quickly.

[0028] In this embodiment, as Figure 1 , Figure 2and Figure 3 As shown, the internal structural dimensions of the chute 405 are consistent with the external structural dimensions of the slider 406, and the internal structural dimensions of the connecting block 407 are consistent with the external structural dimensions of the bellows 403. Generally, impurities in the filter screen 5 accumulate inside the filter screen 5, causing impurity buildup. It is necessary to disassemble and clean or replace the filter screen 5 to avoid clogging and affecting its use. The fan 404 causes the bellows 403 to suck out the impurities inside the filter screen 5. The bellows 403 is connected to the connecting block 407. The outer wall of the connecting block 407 is provided with a slider 406. The slider 406 can move within the chute 405 to facilitate the suction out of impurities.

[0029] In this embodiment, as Figure 1 , Figure 2 and Figure 3 As shown, the internal structural dimensions of the outer cylinder 1 are consistent with the external structural dimensions of the filter screen 5; the outer cylinder 1 and the filter screen 5 can facilitate filtration. To filter items, rotate the threaded rod 402 to move the threaded rod 402 out of the cover plate 401, making it easy to take out the filter screen 5 inside the outer cylinder 1 for cleaning and maintenance, and facilitating overall cleaning of the equipment.

[0030] The method of use and advantages of this utility model: This filter device, which is easy to clean internally, operates as follows:

[0031] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the material to be filtered is first poured into the feed inlet 2, allowing it to enter the filter screen 5 to filter impurities. The motor 504 drives the first bevel gear 503 to rotate clockwise. The first bevel gear 503 meshes with the second bevel gear 502. The second bevel gear 502 rotates clockwise in sequence, driving the rotating shaft 508, the internal frame 506, and the cleaning brush 507 to rotate, thus cleaning the filter screen 5 by rotating the cleaning brush 507 clockwise. The first bevel gear 503 meshes with the third bevel gear 501. The third bevel gear 501 rotates counterclockwise, driving the connecting shaft 509 and the filter screen 5 to rotate, thus achieving rotational filtration by the filter screen 5. The filter screen 5 and the cleaning brush 507 rotate in different directions, facilitating cleaning. The material filtered at the discharge port 3 is then filtered. The blower 404 sucks the impurities inside the filter screen 5 into the collection box 4 through the corrugated pipe 403. Since the cover plate 401 is threadedly connected to the threaded rod 402, it is easy to disassemble the cover plate 401 and remove the internal filter screen 5 for cleaning.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
