For example, "connected" can mean fixed connection, welding, riveting, bonding, etc., or detachable connection, threaded connection, key connection, pin connection, etc., or integral connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediate medium, or it can be internal communication between two components. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood by those skilled in the art in specific circumstances.

[0021] like Figure 1-3As shown, the utility model proposes a dust removal device for a foundry workshop, comprising a first box body 1, a filter plate 2 and a negative pressure fan 3. The first box body 1 is provided with a first opening passing through it, the filter plate 2 is detachably arranged in the first opening, the negative pressure fan 3 is located in the first opening and is spaced apart from the filter plate 2, the negative pressure fan 3 is connected to the inner wall of the first opening through a connecting block 4, and the side end of the first box body 1 is provided with a cleaning component for cleaning the filter plate 2.

[0022] The utility model discloses that when the device needs to be used, the negative pressure generated by the negative pressure fan 3 accelerates the flow of air and makes the air pass through the first box body 1. When the air passes through the first box body 1, it will pass through the filter plate 2, and the impurities in the air can be cleaned through the filter plate 2, and the filtered air is discharged. As time goes by, dust and impurities will gradually accumulate on the filter plate 2, affecting the filtering effect. Therefore, the filter plate 2 can be disassembled and moved to the cleaning component to complete the cleaning of the filter plate 2, thereby ensuring the filtering performance of the filter plate 2, thereby improving the stability of the device during use. The device can effectively filter the air, and the device can also be disassembled to avoid the need for staff to enter the box body 1 to complete the cleaning of the filter plate 2, and there is no need for staff to manually clean the filter plate 2 when cleaning the filter plate 2, thereby effectively reducing the work intensity of the staff and reducing the work difficulty of the staff.

[0023] In an optional embodiment, the cleaning assembly includes a second box body 6 and a fan 7. The first box body 1 is provided with a second opening for the filter plate 2 to pass through. The second box body 6 is connected to the first box body 1. The second box body 6 is provided with a third opening that is interconnected with the second opening at one end facing the first box body 1. The second box body 6 is provided with a fan 7. The bottom end of the second box body 6 is provided with a discharge port. A collection unit is detachably provided at the discharge port. The filter plate 2 can be moved into the second box body 6 and slidably connected to its top wall. The second box body 6 is provided with a driving unit for driving the filter plate 2 to extend into or out of the second opening. When the first box is working, the filter plate 2 One end enters the first opening and slides with the seal therewith, thereby effectively preventing air from extending out of the first opening, and when cleaning the filter plate 2, the filter plate 2 can be moved to block the second opening. When the filter plate 2 needs to be cleaned, the filter plate 2 can be driven to move by the driving unit, and the filter plate 2 moves into the second box body 6. The fan 7 in the second box body 6 can blow the impurities blocked on the filter plate 2 to separate it from the filter plate 2, and the impurities after separating from the filter plate 2 can be collected by the collecting unit. When the filter plate 2 needs to be cleaned, the device moves the filter plate 2 into the second box body 6 to complete the cleaning, without the need to disassemble it, thereby further reducing the workload of the staff.

[0024] In an optional embodiment, the driving unit includes a threaded rod 8, a threaded sleeve 9, a motor 10 and a rotating shaft 17. The end of the second box body 6 away from the first box body 1 is provided with a first through hole, one end of the threaded rod 8 passes through the first through hole and is connected to the filter plate 2, the threaded sleeve 9 is rotatably connected to the end of the second box body 6 away from the first box body 1, the threaded rod 8 is threadedly arranged in the threaded sleeve 9, the motor 10 is connected to the second box body 6, the rotating shaft 17 is rotatably connected to the second box body 6 through the mounting plate 11, and one end of the rotating shaft 17 is connected to the output of the motor 10. The output shaft is coaxially connected to the rotating shaft 17 and is transmission-connected to the threaded sleeve 9. The rotating shaft 17 can be effectively driven to rotate by the motor 10. The rotation of the rotating shaft 17 drives the threaded sleeve 9 transmission-connected thereto to rotate. Since the threaded rod 8 is connected to the filter plate 2, and the filter plate 2 is slidingly connected to the second box body 6, when the threaded sleeve 9 rotates, the threaded rod 8 moves and drives the filter plate 2 to move into the second box body 6, thereby completing the drive of the filter plate 2. The threaded sleeve 9 rotates to drive the threaded rod 8 to move, thereby driving the filter plate 2 to move, and the automatic extension and extension operation of the filter plate 2 can be realized, thereby simplifying the cleaning process and improving the degree of automation of the equipment.

[0025] In an optional embodiment, a first pulley 12 is coaxially provided on the rotating shaft 17, and a second pulley 13 is coaxially provided on the threaded sleeve 9. The first pulley 12 and the second pulley 13 are connected by a belt 14. The rotating shaft 17 drives the first pulley 12 to rotate, and the rotation of the first pulley 12 drives the second pulley 14 to rotate through the belt 13, thereby driving the threaded sleeve 9 coaxially connected thereto to rotate.

[0026] In an optional embodiment, the collection unit includes two limiting plates 15 and a collection box 16. The two limiting plates 15 are spaced apart and connected to one end of the first box body 1 toward the second box body 6. The two limiting plates 15 are located below the second box body 6. A feed port is provided at the upper end of the collection box 16. The collection box 16 is slidably arranged between the two limiting plates 15. The collection box 16 can be moved to the point where the feed port and the discharge port are connected to each other. When in use, the collection box 16 is moved between the two limiting plates 15 so that the feed port is connected to the discharge port. The material inlet and the discharge port are connected to each other, so that after the fan 7 cleans the filter plate 2, the impurities on the filter plate 2 will fall into the collection box 16 under the action of gravity. The staff can take out the collection box 16 from between the two limit plates 15 after using it for a period of time to complete the cleaning of the impurities in the collection box 16. The device can collect the impurities on the filter plate 2 through the collection box 16 without the need for manual collection by the staff, thereby effectively reducing the work intensity of the staff, wherein the upper end of the collection box 16 is slidingly arranged to fit with the bottom end of the second box body 6.

[0027] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all variations and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents thereof.
