[0024] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figure 1-4 The present invention provides a bag filter dust collector, comprising a housing 1, with air inlet pipes 2 symmetrically arranged on both sides near the bottom of the housing 1, a fixing plate 3 fixedly connected to the inner wall near the top of the housing 1, a fan 5 fixedly connected to the top of the fixing plate 3, a movable plate 6 movably connected to the bottom of the housing 1 near the fixing bolt 4, dust collector bags 7 arranged in an array on the top of the movable plate 6, a collection box 8 slidably connected to the bottom of the housing 1, and a vibration negative pressure mechanism provided on the movable plate 6.

[0026] By activating the fan 5 on the fixed plate 3, dusty air enters the housing 1 through the air inlet pipe 2. The dust in the air is filtered by the dust collector bag 7 on the movable plate 6. The filtered air is discharged through the exhaust grille near the top of the rear surface of the housing 1. At the same time, the dust on the dust collector bag 7 is cleaned by the vibration negative pressure mechanism to prevent dust from adhering to the dust collector bag 7 and reducing its filtration effect. Then, the cleaned dust is collected by the collection box 8, thereby improving the practicality of the equipment.

[0027] The vibration negative pressure mechanism includes a drive motor 9 fixedly connected to the side wall of the housing 1. A rotating shaft 10 is provided on the drive motor 9 and passes through the housing 1. Cams 11 are symmetrically arranged on the outer contour of the rotating shaft 10. A reset spring 12 is provided at the four corners near the bottom of the fixed plate 3. The bottom of the reset spring 12 is in contact with the movable plate 6. A rectangular rubber sleeve 13 is slidably connected to the bottom of the movable plate 6. The bottom of the rectangular rubber sleeve 13 is slidably connected to the outer edge of the top of the collection box 8. A fixing block 15 is provided at both ends of the reset spring 12. Fastening bolts 18 are screwed at the four corners of the fixing block 15. A weight sensor 14 is fixedly connected at the four corners of the bottom of the housing 1. The top of the weight sensor 14 is in contact with the bottom of the collection box 8. A warning light 19 is fixedly connected to the top of the housing 1. A buzzer 20 is fixedly connected to the side of the top of the housing 1 near the warning light 19.

[0028] The drive motor 9 rotates the cam 11 on the rotating shaft 10, causing the movable plate 6 to vibrate up and down, thus shaking off the dust adhering to the dust collector bags 7 on the movable plate 6. When the movable plate 6 vibrates initially, the return spring 12 stretches and automatically resets, further enhancing the vibration effect of the movable plate 6. As the movable plate 6 moves up and down, it causes the rectangular rubber sleeve 13 to unfold and compress, using the negative pressure generated by the rectangular rubber sleeve 13 to further enhance the cleaning effect on the dust collector bags 7. The cleaned dust is then collected in the collection box 8, and the weight of the dust in the collection box 8 is monitored by the weight sensor 14. The system monitors the collection box 8. When the weight of the collection box 8 reaches the preset value, it transmits an electrical signal to the controller. The controller then activates the warning light 19 and the buzzer 20 to remind the operator to clean the dust collected in the collection box 8. When the collection box 8 is pulled outward, the bottom of the movable plate 6 slides away from the collection box 8. After the dust collected in the collection box 8 is cleaned, the outer edge of the top of the collection box 8 is then slidably connected to the bottom of the movable plate 6 to improve the practicality of the equipment. If the reset spring 12 is damaged, the operator can remove the fastening bolt 18 on the fixing block 15 and then replace the damaged reset spring 12.

[0029] A sealing door 16 is hinged to the surface of the housing 1. An inspection door 17 is provided on the inner wall of the housing 1 near the fixed plate 3. Fixing bolts 4 that are bolted to the inner wall of the housing 1 are provided at the four corners of the inspection door 17.

[0030] When the fan 5 is damaged, the operator removes the fixing bolts 4, then removes the inspection door 17, and then repairs the fan 5. After the rectangular rubber sleeve 13 is damaged, the sealing door 16 is opened and then the sealing door 16 is pulled to separate the two ends of the rectangular rubber sleeve 13 from the movable plate 6 and the collection box 8. Then the rectangular rubber sleeve 13 is replaced.

[0031] Working principle: The drive motor 9 drives the cam 11 on the rotating shaft 10 to rotate. The cam 11 drives the movable plate 6 to vibrate up and down, thereby shaking off the dust adhering to the dust collector bag 7 on the movable plate 6. When the movable plate 6 vibrates first, the reset spring 12 is stretched and automatically reset, further increasing the vibration effect of the movable plate 6. When the movable plate 6 moves up and down, it drives the rectangular rubber sleeve 13 to unfold and compress. The negative pressure generated by the rectangular rubber sleeve 13 further increases the cleaning effect of the equipment on the dust collector bag 7. The cleaned dust is then collected by the collection box 8. The weight sensor 14 monitors the weight of the dust in the collection box 8. When the weight of the collection box 8 reaches the preset value, an electrical signal is transmitted to the controller. The controller then activates the warning light 19 and the buzzer 20 to remind the operator to clean the dust collected in the collection box 8.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
