[0032] In the embodiment, the dust removal box 1 is fixedly connected with a connecting plate 5 inside. A plurality of dust removal frameworks 6 are bolted to the connecting plate 5. Each dust removal framework 6 is fixedly connected with a dust removal cloth bag 7 outside.

[0033] The connecting plate 5 can provide installation support for the dust removal framework 6. The connecting plate 5 is provided with a perforation for the installation of the dust removal framework 6. The dust removal framework 6 is passed through the perforation, and then the dust removal framework 6 is limited on the connecting plate 5 by using bolts. The shape of the dust removal framework 6 is cage-shaped, which is mainly composed of a support ring and a longitudinal rib. The dust removal framework 6 is used to stabilize and support the dust filtering position of the dust removal cloth bag 7. The dust removal cloth bag 7 is in a cylindrical structure. The dust removal cloth bag 7 can adopt organic fiber or inorganic fiber filter material.

[0034] In the embodiment, the baffle 15 is arranged on one side of the air inlet pipe 3.

[0035] The arrangement of the baffle 15 can be used to change the flow direction of the exhaust gas at the outlet of the air inlet pipe 3, so that the exhaust gas is evenly filtered through the dust cloth bag 7.

[0036] In this embodiment: the top of the dust skeleton 6 is bolted with a fixed disc 8, the fixed disc 8 is rotatably connected with a support frame 9, the support frame 9 extends into the dust cloth bag 7, and the support frame 9 is composed of a pair of circular rings and a pair of pull plates fixed on the circular rings.

[0038] In this embodiment: the inner side of the support frame 9 is detachably connected with a shaft rod 10, a pair of pull plates are fixedly connected with a support block 16, and the shaft rod 10 is rotatably connected with the support block 16.

[0039] The support block 16 can provide rotary support for the shaft rod 10 based on the inner side of the support frame 9, and the shaft rod 10 can provide power transmission for subsequent dust cleaning of the dust cloth bag 7.

[0040] In this embodiment; the shaft rod 10 is fixedly connected with a support plate 22, the support plate 22 is bolted with an assembly plate 23, the assembly plate 23 is bolted with an assembly plate 23, the assembly plate 23 is provided with a flexible component 11, the flexible component 11 includes a rotating column 111, the rotating column 111 is rotatably connected with the assembly plate 23, a torsional spring 112 is sleeved on the outer side of the rotating column 111, the two ends of the torsional spring 112 are fixedly connected with the rotating column 111 and the assembly plate 23 respectively, and a striker 12 is fixedly connected with one end of the rotating column 111.

[0041] In use, by providing rotary power for the shaft rod 10, the rotation of the shaft rod 10 can drive the assembly plate 23 to rotate, the assembly plate 23 can provide position support for the flexible component 11, the rotation of the assembly plate 23 can drive the striker 12 on the rotating column 111 to rotate, and since the dust skeleton 6 is arranged in a cage structure, after the striker 12 is blocked by the longitudinal ribs of the dust skeleton 6, the striker 12 can drive the rotating column 111 to rotate, the rotation of the rotating column 111 can deform the torsional spring 112, and after the striker 12 is separated from the longitudinal ribs of the dust skeleton 6, the elastic force of the torsional spring 112 can drive the striker 12 on the rotating column 111 to return to the initial position, so that the striker 12 can continue to impact and contact the longitudinal ribs of the dust skeleton 6, so as to provide vibration power, and by transmitting the vibration power from the dust skeleton 6 to the dust cloth bag 7, the dust on the outer surface of the dust cloth bag 7 can be conveniently shaken off.

[0042] And the assembly plate 23 is bolted on the support plate 22, which can provide convenience for disassembly and assembly of the flexible component 11 and the striker 12.

[0043] In the embodiment, the top of one of the annular rings is fixedly connected with a rotating ring 17, the rotating ring 17 is rotatably connected with the fixed disc 8, the shaft rod 10 is boltedly connected with a connecting rod 18, the rotating ring 17 is fixedly connected with a fixed block 19, one end of the connecting rod 18 is boltedly connected with the fixed block 19, and the pull plate is movably connected with the impact block 12.

The shaft rod 10 is connected with the fixed block 19 and the shaft rod 10 through bolts at both ends of the connecting rod 18, so that the shaft rod 10 cannot rotate on the support block 16. When an external force drives the rotating ring 17 to rotate, the support frame 9 and the shaft rod 10 can rotate synchronously.

[0045] When the bolts at both ends of the connecting rod 18 are removed, the shaft rod 10 has the rotatability on the support block 16 at this time. The process is to take out all the structures in the dust removal framework 6. Specifically, since the impact block 12 is arranged to achieve the impact contact with the longitudinal ribs of the dust removal framework 6, the length of the impact block 12 is limited by the support ring of the dust removal framework 6 arranged transversely when the impact block 12 is taken out and moved upward. Therefore, by removing the rotation of the shaft rod 10 and the support frame 9, the support frame 9 including the pull plate can push the impact block 12 by rotating the support frame 9. The impact block 12 can rotate on the assembly plate 23 through the rotating column 111 until the impact block 12 is inwardly stored. In this way, the impact block 12 can avoid the position of the support ring, so as to facilitate the taking out of the support frame 9 and the structures thereon.

[0048] It is worth noting that the top of the dust removal box 1 in the present application can be provided with a detachable box cover, one end of the pulse blowing pipe 13 is bolted in the dust removal box 1, the other end of the pulse blowing pipe 13 is connected to the electromagnetic pulse valve 132 through a flange, so that the pulse blowing pipe 13 can be conveniently taken out in the dust removal box 1, by reserving an effective interval on the inner top of the dust removal box 1, the position of the dust removal framework 6 can be conveniently taken out by the detachable support frame 9.

[0049] In the embodiment, the pulse blowing pipe 13 is provided with a wind pressure driving structure 14 for driving the shaft rod 10 to rotate, the wind pressure driving structure 14 includes a fan blade 141, the fan blade 141 is arranged in the pulse blowing pipe 13, a transmission rod 142 is fixedly connected to the fan blade 141, the transmission rod 142 is sealingly and rotatably connected to the pulse blowing pipe 13, a gear 21 is fixedly connected to one end of the transmission rod 142 away from the fan blade 141, an outer gear ring 20 is fixedly connected to the outer surface of the rotating ring 17, and the gear 21 is meshingly connected with the outer gear ring 20.
