A return spring 11 is fixed between the pulling plate 10 and the fixing plate 8. A plurality of parallel fixing grooves 12 are provided on the upper surface of the moving plate 3 along its length direction. The fixing grooves 12 are engaged with the fixing strip 9. Among them, the return spring 11 can ensure the stable engagement between the fixing strip 9 and the fixing grooves 12, and there will be no separation without external force, which can ensure the stability during the cleaning process of the cleaning brush 7. A handle 14 is fixed on the other side side wall of the dust removal plate 1. The handle 14 is perpendicular to the dust removal plate 1. The staff can hold the handle 14, and the handle 14 drives the dust removal plate 1 to move for dust removal.

[0021] A collection table 13 is fixed on the upper surface of the dust removal plate 1. A collection channel 15 penetrating left and right is opened on one side wall of the collection table 13. An installation plate 16 is fixed on one side wall of the collection channel 15. A rotary motor 17 is fixed on one side wall of the installation plate 16. The output shaft of the rotary motor 17 passes through the installation plate 16 and is fixed with symmetrically distributed fan blades 23. Symmetrically distributed connecting grooves 19 are opened on the inner walls of both sides of the collection channel 15. A filter screen 18 is connected between the interiors of the collection channel 15. Connecting strips 20 are fixed on the outer walls of both sides of the filter screen 18. The connecting strips 20 are in snap-fit with the connecting grooves 19. Symmetrically distributed stoppers 21 are rotatably connected to the outer wall of the collection table 13. The stoppers 21 limit the connecting strips 20, enabling quick disassembly and assembly of the filter screen 18, facilitating the cleaning of the collected dust. A collection groove 22 is opened on the bottom side wall of the collection channel 15. The collection groove 22 is located below the filter screen 18, capable of collecting the dust on the filter screen 18.

[0022] This solution has the following working process: When cleaning the dust inside the vacuum furnace, hold the handle 14. The handle 14 drives the dust removal plate 1 to move. The dust removal plate 1 drives the cleaning brush 7 to move. Start the drive motor 4 and the rotary motor 17. The drive motor 4 drives the connecting shaft 5 to rotate. The connecting shaft 5 drives the cleaning disc 6 to rotate. The cleaning disc 6 drives the cleaning brush 7 to rotate to clean the inner wall of the vacuum furnace. At the same time, the rotary motor 17 drives the fan blades 23 to rotate. The wind force generated by the fan blades 23 causes the cleaned dust to enter the interior of the collection channel 15. The dust is filtered by the filter screen 18. When cleaning different depths and positions, only need to pull the pull plate 10. The pull plate 10 drives the fixing strip 9 to move. The fixing strip 9 is separated from the fixing groove 12. Then push the moving plate 3. The moving plate 3 drives the cleaning brush 7 to adjust the position. After adjusting to the required position, release the pull plate 10. Under the elastic force of the return spring 11, the fixing strip 9 is in snap-fit with the corresponding fixing groove 12 to fix the position of the moving plate 3. When cleaning the filter screen 18, rotate the stopper 21 so that the stopper 21 no longer limits the connecting strip 20. Then move the filter screen 18. The filter screen 18 drives the connecting strip 20 to move out of the connecting groove 19 for disassembly and cleaning of the filter screen 18.
