Description

Technical Field

[0001] The utility model relates to the technical field of particle separators of hollow filters made of flexible materials, in particular to a smoke collecting device for welding workshops. Background Art

[0002] In welding workshops, welding operations generate large amounts of smoke and harmful gases. These pollutants not only seriously pollute the workshop environment but also pose a threat to the health of workers. Therefore, effective smoke collection and purification equipment is crucial to improving the workshop environment and protecting workers' health.

[0003] Traditional fume collection devices in welding workshops mostly use filter bags or filter cartridges as filter elements to separate fume from the air by filtering. However, these devices have some problems during long-term use. Although the pulse cleaner can remove the fume on the surface of the filter cartridge to a certain extent, in the high-concentration and high-viscosity welding fume environment, the filter cartridge is still prone to local blockage or incomplete cleaning. This blockage not only affects the filtration efficiency of the dust collector, but may also shorten the service life of the filter cartridge and increase maintenance costs. Therefore, we propose a fume collection device for welding workshops. Utility Model Content

[0025] See also Figure 1-4 The utility model provides a technical solution: a fume collection device for a welding workshop, comprising:

[0026] Mounting frame 1, downflow cartridge dust collector 2, filter cartridge 3, blower 5 and chimney 6. Downflow cartridge dust collector 2 is mounted inside mounting frame 1, and filter cartridge 3 is mounted inside downflow cartridge dust collector 2.

[0027] The filter cartridge cleaning structure is located on the downflow filter cartridge dust collector 2;

[0028] The filter cartridge cleaning structure includes two fixed frames 13, two drive motors 10, four threaded rods 11 and two belts 12. The four threaded rods 11 are all rotatably connected to the inside of the downflow filter cartridge dust collector 2, and one end of the four threaded rods 11 is rotated and extended to the outside of the downflow filter cartridge dust collector 2. The two belts 12 are respectively driven and sleeved on the outer surfaces of the corresponding two threaded rods 11. The two belts 12 are both located on the outside of the downflow filter cartridge dust collector 2. The two fixed frames 13 are both fixedly connected to the side of the downflow filter cartridge dust collector 2 close to the two belts 12. The two drive motors 10 are both fixedly installed on the corresponding fixed frames 13. The output ends of the two drive motors 10 are rotated through the corresponding fixed frames 13 and are fixedly connected to the corresponding threaded rods 11.

[0029] The filter cartridge cleaning structure also includes two first cleaning frames 14 and two second cleaning frames 16. The two first cleaning frames 14 are installed with the corresponding second cleaning frames 16 by bolts, wherein the corresponding first cleaning frames 14 and the second cleaning frames 16 are respectively threadedly sleeved on the outer surfaces of the corresponding two threaded rods 11, and the two first cleaning frames 14 and the corresponding second cleaning frames 16 are in contact with the corresponding filter cartridge 3.

[0030] A clean gas chamber 7 is fixedly connected to the side of the downflow cartridge dust collector 2 away from the two drive motors 10, and a high-pressure gas storage tank 9 is fixedly installed on the side of the clean gas chamber 7 away from the downflow cartridge dust collector 2. A pulse cleaning system 15 is fixedly installed on the high-pressure gas storage tank 9. The end of the pulse cleaning system 15 away from the high-pressure gas storage tank 9 corresponds to the corresponding filter cartridge 3, and an air outlet 8 is opened on one side of the clean gas chamber 7.

[0031] The air inlet device on the downflow cartridge dust collector 2 is connected to the air collecting hood 4 through a pipeline, the air outlet 8 is connected to the air blower 5 through a pipeline, and the air blower 5 is connected to the inside of the chimney 6 through a pipeline.

[0032] Furthermore, when using the device, the two drive motors 10 are started by connecting an external power supply. The two drive motors 10 will drive the corresponding threaded rods 11 to rotate. The rotation of the threaded rods 11 close to the two drive motors 10 will drive the threaded rods 11 away from the two drive motors 10 to rotate through the corresponding belts 12. The rotation of the four threaded rods 11 will drive the first cleaning rack 14 and the second cleaning rack 16 thereon to move, thereby facilitating the first cleaning rack 14 and the second cleaning rack 16 to clean the outer surface of the filter cartridge 3. The dust-laden gas enters the downflow filter cartridge dust collector 2 through the gas collecting hood 4, and enters the filter cartridge 3 after buffering. The dust in the exhaust gas is intercepted by the filter cloth on the surface of the filter cartridge 3. Larger dust falls directly into the ash hopper, and fine dust is deposited on the filter material surface through the combined effects of Brownian diffusion and screening. As time goes by, more and more dust accumulates on the filter cloth, and the resistance increases, affecting the dust removal effect. At this time, the pulse cleaning device starts to work, using compressed air to expand and deform the filter cartridge, generating vibrations, shaking off the accumulated dust, and causing the dust to fall into the ash hopper. After filtration, the dust in the exhaust gas is intercepted, and the clean exhaust gas is discharged into the atmosphere through the air outlet 8.

[0033] Through the cooperation of the first cleaning frame 14, the second cleaning frame 16, the threaded rod 11 and the belt 12, the threaded rod 11 can drive the first cleaning frame 14 and the second cleaning frame 16 to move horizontally, thereby facilitating the cleaning of the outer surface of the filter cartridge 3, avoiding local blockage or incomplete cleaning of the filter cartridge 3, and further improving the filtration efficiency of the dust collector.

[0034] Working principle: By connecting an external power supply to start the two drive motors 10, the two drive motors 10 will drive the corresponding threaded rods 11 to rotate. The rotation of the threaded rods 11 close to the two drive motors 10 will drive the threaded rods 11 away from the two drive motors 10 to rotate through the corresponding belts 12. The rotation of the four threaded rods 11 will drive the first cleaning rack 14 and the second cleaning rack 16 thereon to move, thereby facilitating the first cleaning rack 14 and the second cleaning rack 16 to clean the outer surface of the filter cartridge 3.

[0035] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the purpose of the present invention.
