Based on the embodiments of the utility model, all other implementation methods obtained by ordinary technicians in this field without creative work belong to the scope of protection of the utility model.

[0025] First embodiment:

[0026] See also Figure 1-Figure 4 As shown, the utility model provides a dust explosion-proof bag dust collector, including a chassis 1, an air intake connecting pipe 2 is connected to the outside of the chassis 1, a hose 3 is connected to the air intake end of the air intake connecting pipe 2, an exhaust port and a dust port are respectively provided at the upper and lower parts of the chassis 1, and a fan is provided at the exhaust port of the chassis 1, so that the fan can make air enter the inside of the chassis 1 through the opening of the hose 3 and the air intake connecting pipe 2, and after filtering the gas in the chassis 1, it is guided out from the exhaust port of the chassis 1;

[0027] A sealing plate 101 is provided inside the chassis 1 and is located above the air inlet connecting pipe 2. A plurality of cloth bags 6 are connected to the sealing plate 101. A telescopic cylinder 7 is provided on the inner wall of the chassis 1. The telescopic end of the telescopic cylinder 7 extends upward and is connected to a mesh plate 701. The mesh plate 701 is connected to the high ends of all the cloth bags 6. After the telescopic cylinder 7 is extended, the telescopic cylinder 7 can pull the sealed end of the cloth bag 6 to move upward, and the gas is filtered through the cloth bag 6. After the gas filtration is completed, the telescopic cylinder 7 is shortened, and the telescopic cylinder 7 pushes the sealed end of the cloth bag 6 downward, and the dust inside the cloth bag 6 can fall through the opening of the cloth bag 6 to the dust outlet, thereby assisting the falling of the dust.

[0028] In a preferred embodiment, the exhaust port is in a conical surface, and an exhaust valve is provided at the opening thereof. After the exhaust valve is opened, the dust inside the chassis 1 can be easily discharged;

[0029] Furthermore, a dust detector 5 for detecting dust inside the chassis 1 is connected to the chassis 1 , and the dust detector 5 is close to the exhaust port of the chassis 1 .

[0030] The second embodiment is different from the first embodiment in that:

[0031] An annular tube 4 connected to the air inlet end of the air inlet connecting pipe 2 is provided on the outside of the chassis 1, and a plurality of air guide tubes 401 with through holes are provided on the annular tube 4. By using the through holes on the air guide tube 401 located on the outside of the chassis 1, gas can enter the inside of the air guide tube 401 through the through holes, and be guided to the inside of the chassis 1 through the annular tube 4 and the annular tube 4, so that dust around the device can be cleaned;

[0032] In a preferred embodiment, the air ducts 401 extend vertically and are evenly distributed on the outside of the chassis 1 .

[0033] The third embodiment is different from the first embodiment in that:

[0034] In the structure of the cloth bag 6, the bottom of the cloth bag 6 is an open structure, and the opening is detachably connected to the sealing plate 101 through a threaded ring 102. The threaded ring 102 is an annular structure, which can realize the compression and fixation of the opening of the cloth bag 6. The high end of the cloth bag 6 is provided with a connecting piece 601, and the connecting piece 601 can realize the connection between the cloth bag 6 and the connecting piece 601 by bolts or adhesive. The bottom surface of the mesh plate 701 is rotatably connected with a rotating cap 703 through a vertical rod 702, and the rotating cap 703 is threadedly connected to the connecting piece 601. The high end of the cloth bag 6 is fixed by threading the connecting piece 601 and the rotating cap 703;

[0035] The cloth bag 6 is in a cylindrical or conical structure, and its small end is fixedly connected to the connecting piece 601. In this way, after the telescopic cylinder 7 is shortened, the vertical rod 702 pushes the cloth bag 6 to move downward, and the cloth bag 6 can be pushed to the bottom of the chassis 1, so that the dust inside the cloth bag 6 can be discharged through the dust port. When the cloth bag 6 is in a conical shape, the cloth bag 6 can be turned down more quickly to assist in the discharge of dust inside the cloth bag 6.
