The both ends of pivot 33 are overlapped respectively and are equipped with torsional spring 35, and the one end and the apron 34 fixed connection of torsional spring 35, the other end and baffle 31 fixed connection. When the air pressure in the box body 1 is too large, the cover plate 34 is jacked up by air, and then the air is discharged from the through holes 311, so that the air pressure in the box body 1 is reduced, and the safety of the bag-type dust collector is improved. After the air is exhausted, the cover plate 34 is turned downward by the torsion spring 35 to cover the through hole 311, so that the air is not easily exhausted. The rubber sheet is arranged, so that the buffering force of the cover plate 34 on the baffle 31 can be reduced, the service life of the cover plate 34 is prolonged, and the sealing performance of the cover plate 34 can be improved.

As shown in fig. 1, in order to increase the efficiency of gas discharge, a guide slope 3111 is provided at one end of the penetration hole 311 near the case 1.

As shown in fig. 1, a cleaning device 4 is provided above the explosion-proof device 2, and the cleaning device 4 is disposed symmetrically with respect to the axis of the pressure relief frame 21. Each cleaning device 4 includes a support plate 41 vertically fixed to the pressure-releasing frame 21, and a dust cover 42 is fixedly attached to the support plate 41. The dust cover 42 is internally provided with a driving motor 43 fixed on the supporting plate 41, a rotor of the driving motor 43 is fixedly connected with a lead screw 431, the lead screw 431 is in threaded connection with a cleaning plate 44, one side of the cleaning plate 44 close to the inner wall of the pressure relief frame 21 is provided with a hard hairbrush 441, and the hard hairbrush 441 is in contact with the inner wall of the pressure relief frame 21. A travel switch 45 electrically connected with the driving motor 43 is fixedly connected to the inner wall of the pressure relief frame 21, and the travel switches 45 are located at two ends of the screw 431. When the cleaning device 4 is used, the driving motor 43 drives the screw rod 431 to rotate, in the process of rotating the screw rod, the cleaning plate 44 moves along the screw rod 431, when the screw rod 431 moves to the position of the travel switch 45, the travel switch 45 sends a signal to the driving motor 43, the driving motor 43 receives the signal and then reverses, and then the cleaning plate 44 is driven to move reversely, so that the cleaning plate 44 is driven to move up and down, dust on the inner wall of the pressure relief frame 21 is brushed off, and the service life of the pressure relief frame 21 is prolonged. After the cover plate 34 is opened, the air pressure can discharge the brushed dust together.

As shown in fig. 1, in order to make the cleaning plate 44 more stable in operation, a guide rod 411 is vertically and fixedly connected to a side of the supporting plate 41 facing the cabinet 1, and the cleaning plate 44 moves axially along the guide rod 411.

The specific implementation process comprises the following steps: when the air pressure in the box body 1 is higher than the air pressure when the dust remover works normally, the cover plate 34 is jacked up by the air, and the redundant air is discharged from the through hole 311, so that the pressure relief is realized. After the air pressure is exhausted, the cover plate 34 is turned downwards under the action of the torsion spring 35, so that the lower bottom surface of the cover plate 34 is in contact with the upper surface of the baffle plate 31, the through hole 311 is sealed, and the bag-type dust collector can work normally.

When dust adheres to the inner wall of the pressure release frame 21, the driving motor 43 is started, the driving motor 43 drives the lead screw 431 to rotate, so that the cleaning plate 44 moves along the lead screw 431, and the hard hairbrush 441 brushes the dust on the inner wall of the pressure release frame 21 during the movement of the cleaning plate 44. When the cleaning plate 44 approaches the travel switch 45, the travel switch 45 sends a signal to the driving motor 43 after receiving the signal, and the driving motor 43 reverses after receiving the signal, thereby moving along the lead screw 431. Some dust brushed off by the hard brush 441 is collected on the filter frame 5, and some dust falls on the cover plate 34. When the cover plate 34 is opened again, the dust deposited on the cover plate 34 is discharged together with the gas in the case 1 to be accumulated on the filter frame 5. When the dust accumulated on the filter frame 5 is more, the filter frame 5 can be drawn out to replace the new filter frame 5, so that the filtering effect is improved, and the dust is reduced to be discharged into the air.

In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
