AI Technical Summary

Technical Problem

During the filtration process, existing dust explosion-proof bag dust collectors will still adhere to the outer surface of the filter rod, affecting the filtration efficiency and lacking explosion-proof devices, making dust explosions prone to occur.

Method used

A dust explosion-proof bag dust collector is designed, which uses a combination of filtering mechanism and explosion-proof mechanism. The filtering mechanism automatically cleans up dust on the surface of the filter cartridge through the wind wheel drive cleaning plate to prevent clogging. The explosion-proof mechanism uses dust concentration detection sensors and water pump system to monitor dust concentration in real time. When the concentration is too high, the water spray pipe frame sprays water to wet the dust, reducing the risk of dust explosion.

Benefits of technology

The automatic cleaning function of the dust collector is realized, which extends the device's service time, and through real-time monitoring and wetting of dust, it significantly reduces the risk of dust explosion and improves the explosion-proof performance of the dust collector.

Description

Technical Field

[0001] The utility model belongs to the technical field of bag dust collectors, and particularly relates to a dust explosion-proof bag dust collector. Background Art

[0002] Bag filter is a kind of equipment used to remove dust and particles from the air. Bag filter is a highly efficient dust removal equipment. Its core component is the filter bag, which is made of special materials and has high filtration efficiency and durability. When the air passes through the filter bag, the particles and dust in it will be blocked by the filter bag, and the clean air will enter the lower part of the dust collector through the filter bag.

[0003] The Chinese patent with the publication number of "CN219324027U" discloses a dust explosion-proof bag filter, which includes a support leg, a filter air box above the support leg, and an air outlet box above the filter air box, the support leg is fixedly mounted on the four corners of the filter air box, a suction pipe is arranged on the right side of the filter air box, one side of the suction pipe is fixedly connected to the filter air box, a dust hood is arranged at the end of the other side of the suction pipe, and the suction pipe and the dust hood are fixedly connected together. In the utility model, the suction force of the air blowing device can be amplified by the suction pipe and the dust hood, and the dust on the raw material can be sucked down, so as to achieve the effect of directly sucking away the dust on the raw material and avoiding environmental pollution; the dust enters the dust reduction box in the filter air box through the suction pipe, and the air will hit the bottom of the dust reduction box with the dust, and then the larger dust particles will fall, effectively reducing the filtering pressure of the filter rod, so as to achieve the effect of extending the use time of the device.

[0004] Although the above-mentioned device can help reduce the filtering pressure of the filter rod during use, it can only reduce the filtering pressure during the filtering process. Dust will still adhere to the outer surface of the filter rod during the filtering period, which will still affect the efficiency of dust filtration. In addition, there is a lack of corresponding explosion-proof devices during the filtering process. Once the dust concentration inside the bag dust collector is high, it is very easy to cause a dust explosion. It can be seen that the existing equipment has certain defects and shortcomings and needs to be improved. Utility Model Content

[0032] Principle and advantages of use: By setting the filtering mechanism 5, the device can be operated by the suction fan 7 during use. The suction fan 7 generates suction force to absorb dust and air into the interior of the dust collector. At this time, the air is assisted by the filter cartridge 54 for filtration. The air filtered by the filter cartridge 54 is discharged into the exhaust hopper 4 through the circular groove 52, and the filtered dust can fall into the interior of the collecting mechanism 10. At this time, since the air is discharged through the circular groove 52, the air can blow the wind wheel 53 inside the circular groove 52 to rotate. The wind wheel 53 can drive the connecting shaft 55 to rotate when it is in a rotating state. The cleaning plate 56 at the lower end of the connecting shaft 55 can be driven to rotate through the rotation of the connecting shaft 55. At this time, the cleaning plate 56 is attached to the outer surface of the filter cartridge 54, and the dust and impurities on the outer surface of the filter cartridge 54 can be scraped off, so that the device can have a strong dustproof function, the phenomenon of the filter cartridge 54 being blocked can be avoided, and the overall performance of the device can be improved.

[0033] By setting up the explosion-proof mechanism 9, during the use of the device, the dust concentration inside the dust collector body 3 can be detected by the dust concentration detection sensor in the single-chip controller 96. When the dust concentration is too high, the operation of the water pump 92 can be controlled by the single-chip operation, and the water pump 92 is connected to the water supply pipe through the threaded joint at the outer end of the connecting pipe 93, and can supply water through the water supply pipe. At this time, water can be sprayed through the water spray pipe rack 94 and the nozzle 95 thereon, and the dust inside the dust collector body 3 is wetted by the water, which can make the dust inside the collecting mechanism 10 in a moist state, and can prevent the dust inside the collecting mechanism 10 from rolling and floating, thereby reducing the dust concentration content in the air, and can have better explosion-proof performance and avoid dust explosion.
