Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0031] The present invention will be further described below with reference to the embodiments.
[0032] See attached document Figure 1-9 A dust suppression device for powder coating includes a powerful fan 2, the base of which is fixed above a dust suppression chamber 1. The input pipe of the powerful fan 2 extends into the upper part of the dust suppression chamber 1. A dust collection box 5 is movably connected inside the powerful fan 2. A filter assembly 4 is movably connected inside the powerful fan 2. A processing assembly 3 is provided on the side of the powerful fan 2. The processing assembly 3 includes an air inlet pipe 31. The end of the air inlet pipe 31 is embedded in the side plate of the dust suppression chamber 1. An arc-shaped notch 32 is opened on the outside of the air inlet pipe 31. A baffle plate 33 is inserted inside the arc-shaped notch 32. When the powerful fan 2 is started, the processing assembly 3 draws air into the dust suppression chamber 1. The baffle plate 33 inside the air inlet pipe 31 performs preliminary filtration of the air entering the dust suppression chamber 1. The powerful fan 2 inside the dust suppression chamber 1 performs secondary filtration of the incoming air. The dust in the filtered air falls into the dust collection box 5 for collection.
[0033] In the above technical solution, an air inlet pipe 31 is set on the side of the dust settling box 1, and the outside of the barrier mesh 33 is inserted into the arc-shaped notch 32. When the powerful fan 2 is started, the processing component 3 draws air into the interior of the dust settling box 1. The barrier mesh 33 inside the air inlet pipe 31 performs preliminary filtration on the air entering the dust settling box 1. The outside of the filter component 4 is inserted into the dust settling box 1, and the powerful fan 2 inside the dust settling box 1 performs secondary filtration on the incoming air. The dust in the filtered air falls into the dust collection box 5 for collection.
[0034] According to some embodiments of this utility model, the filter assembly 4 includes a sealing frame 41, and a filter screen mounting port 42 is provided above the sealing frame 41. A filter screen plate 43 is movably installed in the filter screen mounting port 42. The top surface of the filter screen plate 43 abuts against the bottom surface of the pressing plate 45. The outside of the pressing plate 45 is rotatably disposed in a groove 44. The groove 44 is opened above the sealing frame 41 and is connected to the filter screen mounting port 42. By movably installing the outside of the filter screen plate 43 in the filter screen mounting port 42, when the knob presses the plate 45, the filter screen plate 43 can be securely locked in the filter screen mounting port 42. Therefore, the filter screen plate 43 filters the air dust entering the dust settling box 1. When the knob of the pressing plate 45 is turned into the groove 44, the sealing frame 41 is pulled out from the dust settling box 1, thereby realizing the disassembly and replacement of the filter screen plate 43.
[0035] According to some embodiments of this utility model, the inner wall of the sealing frame 41 is fixedly connected to the end of the fixing plate 46, the side of the fixing plate 46 is provided with a movable plate 48, the top surface of the movable plate 48 is fixedly connected with a mounting bracket, the mounting bracket is fixedly connected with a brush plate 47 by bolts, the top of the brush plate 47 is in close contact with the bottom of the filter screen plate 43. By setting the movable plate 48 on the side of the fixing plate 46 and then setting the brush plate 47 on the top surface of the movable plate 48, when the movable plate 48 moves on the fixing plate 46, the brush plate 47 cleans the bottom of the filter screen plate 43 of the dust that has not fallen off, so as to prevent the dust accumulation at the bottom of the filter screen plate 43 from affecting the ventilation and dust reduction effect of the dust collection box 1.
[0036] According to some embodiments of this utility model, a driving component 49 is fixedly connected inside the movable plate 48. The driving component 49 has an opening, and a toggle lever 9 is sleeved in the opening. The end of the toggle lever 9 is fixed to the outside of the driving wheel 10. The inner wall of the driving wheel 10 is fixed to the end of the output shaft of the motor 7. The base of the motor 7 is fixed to the outside of the fixed plate 46. The terminal of the motor 7 is electrically connected to the terminal of the battery box 6. The base of the battery box 6 is fixed to the outside of the fixed plate 46. When the motor 7 is started, the driving wheel 10 drives the toggle lever 9 to rotate, thereby causing the driving component 49 and the movable plate 48 to move back and forth on the surface of the fixed plate 46 through the toggle lever 9. Therefore, the brush plate 47 at the top of the movable plate 48 can automatically clean the dust at the bottom of the filter screen plate 43.
[0037] According to some embodiments of the present invention, a support rod is fixedly connected to the outside of the fixed plate 46. The support rod is rotatably connected to the inside of the guide wheel 8. An annular groove is provided on the outside of the guide wheel 8. The annular groove on the outside of the guide wheel 8 abuts against the outside of the driving member 49. By providing an annular groove on the outside of the guide wheel 8 and abutting against the outside of the driving member 49, when the moving plate 48 moves automatically back and forth outside the fixed plate 46, the guide wheel 8 provides a guiding, limiting and supporting effect on the driving member 49.
[0038] In the above technical solution, the filter screen plate 43 is externally and movably installed in the filter screen mounting port 42. When the knob presses the plate 45, the filter screen plate 43 can be securely locked in the filter screen mounting port 42. Therefore, the filter screen plate 43 filters the air dust entering the dust settling chamber 1. When the knob of the pressing plate 45 is turned into the groove 44, the sealing frame 41 is pulled out from the dust settling chamber 1, thereby realizing the disassembly and replacement of the filter screen plate 43. When the moving plate 48 moves on the fixed plate 46, the brush plate 47 cleans the bottom of the filter screen plate 43 of the dust that has not fallen off, thus preventing the filter screen from being damaged. Dust accumulation at the bottom of plate 43 affects the ventilation and dust suppression effect of dust collection box 1. When the motor 7 is started, the drive wheel 10 drives the lever 9 to rotate, thereby causing the drive component 49 and the moving plate 48 to move back and forth on the surface of the fixed plate 46. As a result, the brush plate 47 on the top of the moving plate 48 can automatically clean the dust at the bottom of the filter plate 43. By opening an annular groove on the outside of the guide wheel 8 and pressing the annular groove against the outside of the drive component 49, when the moving plate 48 moves back and forth automatically outside the fixed plate 46, the guide wheel 8 provides a guiding and limiting support effect for the drive component 49.
[0039] Working principle: An air inlet pipe 31 is installed on the side of the dust collection chamber 1, and the external part of the filter screen 33 is inserted into the arc-shaped notch 32. When the powerful fan 2 is started, the processing component 3 draws air into the dust collection chamber 1, thereby performing preliminary filtration of the air entering the dust collection chamber 1 through the filter screen 33 inside the air inlet pipe 31. By inserting the external part of the filter component 4 into the dust collection chamber 1, the powerful fan 2 inside the dust collection chamber 1 performs secondary filtration of the incoming air. The dust in the filtered air falls into the dust collection box 5 for collection. The external part of the filter screen 43 is movably installed in the filter screen mounting port 42. When the knob press plate 45 is turned, the filter screen 43 can be firmly locked in the filter screen mounting port 42. Therefore, the filter screen 43 filters the dust in the air entering the dust collection chamber 1. When the knob of the press plate 45 is turned into the groove 44, the sealing frame 41 is pulled out from the dust collection chamber 1. The filter screen 43 can be disassembled and replaced. A movable plate 48 is set on the side of the fixed plate 46, and a brush plate 47 is set on the top surface of the movable plate 48. When the movable plate 48 moves on the fixed plate 46, the brush plate 47 cleans the dust that has not fallen off the bottom of the filter screen 43, so as to prevent the dust accumulation at the bottom of the filter screen 43 from affecting the ventilation and dust reduction effect of the dust collection box 1. When the motor 7 is started, the drive wheel 10 drives the lever 9 to rotate, thereby moving the drive component 49 and the movable plate 48 back and forth on the surface of the fixed plate 46. Thus, the brush plate 47 on the top of the movable plate 48 can automatically clean the dust at the bottom of the filter screen 43. By opening an annular groove on the outside of the guide wheel 8 and pressing the annular groove against the outside of the drive component 49, when the movable plate 48 moves back and forth automatically outside the fixed plate 46, the guide wheel 8 provides a guiding and limiting support effect for the drive component 49.
