A second handle 16 is fixedly connected to the maintenance door 15. A first fixing block 17 is fixedly connected to the maintenance door 15. A second fixing block 18 is fixedly connected to the middle box body 7. A bolt 19 is threadedly connected to the middle of the first fixing block 17 and the second fixing block 18. A filter screen 28 is fixedly connected inside the dust hopper 6. The reciprocating lead screw 26 penetrates and is rotatably connected to the positioning block 24. The reciprocating lead screw 26 is provided inside the chute 25. The scraper 27 is in close connection with the filter screen 28. The dust hopper 6, the middle box body 7, and the upper box body 8 are communicated with each other. Support legs 5 are fixedly connected to the dust hopper 6. There are four groups of support legs 5 and they are arranged around the dust hopper 6. The dust hopper 6, the middle box body 7, and the upper box body 8 are all composed of Q235A steel plate materials. By providing that the dust hopper 6, the middle box body 7, and the upper box body 8 are all composed of Q235A steel plate materials, the dust removal device can operate safely and stably in an explosive and flammable environment, effectively improving the protection and safety of the dust removal device.
[0033] An upper box door 9 is hinged to the upper box body 8. A groove 12 is provided on the upper box body 8. A first limiting block 11 is arranged in the groove 12. A first handle 10 is fixedly connected to the upper box door 9. A second limiting block 13 is fixedly connected to the upper box body 8. One side of the first limiting block 11 is fixedly connected to the upper box door 9. The middle parts of the first limiting block 11 and the second limiting block 13 are slidably connected to a limiting pin 14. The first limiting block 11 and the second limiting block 13 are arranged in parallel. A ladder 20 is fixedly connected to one side of the middle box body 7. An electromagnetic pulse valve 23 is fixedly connected to the upper box body 8. One side of the electromagnetic pulse valve 23 is arranged inside the upper box body 8. An exhaust valve 29 is fixedly connected to one side of the ash hopper 6. A dust discharge valve 22 is fixedly connected to the bottom of the ash hopper 6. A pulse blower 2 is fixedly connected to the bottom plate 1. A dust suction pipe 3 is fixedly connected to one side of the pulse blower 2.

The side of the dust discharge pipe 4 away from the pulse blower 2 penetrates through and is arranged inside the upper box body 8. An explosion-proof motor 21 is provided. The output end of the explosion-proof motor 21 drives a reciprocating lead screw 26 to rotate. The rotation of the reciprocating lead screw 26 makes the scraper 27 reciprocate along the chute 25 and the reciprocating lead screw 26 under the limitation of the positioning block 24. The reciprocating movement of the scraper 27 further pushes the dust on the filter screen 28, so that the smaller dust passes through the filter screen 28 and falls into the ash hopper 6, enabling the size of the internal particles to be screened during the dust treatment, avoiding the accumulation of larger particles together and causing blockage. By opening the exhaust valve 29, the gas in the ash hopper 6 is discharged. By opening the dust discharge valve 22, the smaller dust in the ash hopper 6 is discharged from the dust discharge valve 22.
[0034] Working principle: In actual use, the dust suction pipe 3 is docked with the dust port, and a pulse blower 2 is set. The dust is sucked through the dust suction pipe 3 and discharged into the upper box body 8 through the dust discharge pipe 4. An electromagnetic pulse valve 23 is set, and the electromagnetic pulse valve 23 controls the dust in the upper box body 8 to move downward and fall onto the filter screen 28. An explosion-proof motor 21 is set, and the output end of the explosion-proof motor 21 rotates to drive the reciprocating screw rod 26 to rotate. The rotation of the reciprocating screw rod 26 causes the scraper 27 to reciprocate along the chute 25 and the reciprocating screw rod 26 under the limit of the positioning block 24. The reciprocating movement of the scraper 27 further pushes the dust on the filter screen 28, so that the smaller dust particles pass through the filter screen 28 and fall into the ash hopper 6, enabling the size of the internal particles to be screened during dust treatment, avoiding the accumulation of larger particles and causing blockage. Open the exhaust valve 29 to discharge the gas in the ash hopper 6, and open the dust discharge valve 22 to discharge the smaller dust in the ash hopper 6 from the dust discharge valve 22. When it is necessary to observe the internal situation of the middle box body 7, rotate the bolt 19, and the bolt 19 rotates and is removed along the fixed block 17. Pull the handle 2 16, and the handle 2 16 rotates and opens. Manually clean the larger dust remaining on the filter screen 28 to avoid dust blockage and affect the dust removal effect. Since the ash hopper 6, the middle box body 7, and the upper box body 8 are all composed of Q235A steel plate materials, the dust removal device can operate safely and stably in an explosive and flammable environment, effectively improving the protection and safety of the dust removal device.
