Description

Technical Field

[0001] The invention belongs to the technical field of dust removal and purification, and specifically relates to a dust removal and purification device for a steel pipe production workshop. Background Art

[0002] The steel pipe production workshop is a comprehensive industrial environment for steel pipe production. Steel pipe production includes multiple steps such as raw material preparation, forming and welding, heat treatment, surface treatment and finishing. Each step will produce different pollutants and impurities, especially in the process of steel pipe forming and welding, which will produce a lot of smoke and dust, so the smoke needs to be removed and purified.

[0003] 1. The welding fume of steel pipe contains metal oxides, fluorides, nitrogen oxides and other fine particles, which are usually filtered by filter elements. After filtering, activated carbon is used for adsorption and deodorization before discharge. The treatment effect on fine particles and harmful gases is poor, and the filter element is directly used for adsorption. Larger particles and impurities are in direct contact with the filter element, which can easily cause the filter element to be blocked and shorten the service life of the filter element.

[0004] 2. Before smoke purification, smoke needs to be sucked. The existing method is usually to lay an exhaust duct on the top of the steel pipe production workshop, and use the exhaust duct to suck the smoke into the purification equipment for purification. However, the steel pipe production workshop is large in area, and the welding smoke is distributed in the bottom, middle and high layers of the workshop's internal space. The top suction method has poor suction effect on the middle and bottom layers, which reduces the purification efficiency.

[0005] 3. During filtration and purification, the filter material that first contacts the smoke has more dust and impurities adsorbed on it, while the filter material that contacts the smoke later has fewer impurities. The first layer of filter material is overused, while the utilization rate of the subsequent filter materials is low, resulting in uneven filtration and reducing the overall purification effect.

The driven gear 615 rotates during the lateral movement, synchronously driving the fixed shaft 613 and the active bevel gear 612 thereon to rotate, and at the same time driving the driven bevel gear 631 to rotate, synchronously driving multiple driven gears 634 to rotate at the same time, and then synchronously driving the rotating sleeve 635 and the annular brush 636 thereon to rotate, and the filter element 12 is cleaned by the rotation of the annular brush 636. The filter element 12 is cleaned by the reciprocating lateral movement and rotation of the annular brush 636, and the cleaning effect is good, which effectively avoids the problem of clogging of the filter element 12, and realizes the linkage between the circulation mechanism 5 and the dust removal and cleaning mechanism 6.

[0049] See also Figure 2 and Figure 8 A plurality of filter elements 12 are fixedly connected to a junction box 11 on the left side through a pipeline, the pipeline is fixedly connected to the partition 7, an exhaust pipe 10 is fixedly connected to the center of the left side of the junction box 11, a suction pump is provided in the middle of the exhaust pipe 10, the exhaust pipe 10 is communicated with the inside of the junction box 11, and a nozzle 14 is fixedly connected to the bottom of the exhaust pipe 10, a water tank 9 is fixedly connected to the left side of the bottom surface of the purification box 1, the water tank 9 contains absorption liquid, and the nozzle 14 is located in the absorption liquid, and a plurality of spray holes are opened at the bottom of the nozzle 14, which is conducive to uniformly transporting the gas filtered by the filter element 12 into the absorption liquid, thereby achieving full contact between the gas and the absorption liquid.

[0050] Start the suction pump to suck the gas filtered by the filter element 12 into the junction box 11, then into the exhaust pipe 10, and then discharged through the nozzle 14. The gas enters the water tank 9 and is adsorbed by the absorption liquid. The adsorbed gas is then sucked by the No. 2 suction fan 15 and further adsorbed by the activated carbon adsorption box 8 before being discharged from the exhaust hole 4, thus realizing multi-stage treatment of smoke.

[0051] It should be noted that when the dust removal and purification device of the steel pipe production workshop is used, the driving motor 261 in the multi-level suction mechanism 2 is started, and the output end of the driving motor 261 drives the transmission shaft 263 and the winding wheel 262 thereon to rotate, and the winding wheel 262 loosens the connection to the steel rope 265, thereby lowering the corrugated folding hose 23 to the lowest position, and the No. 1 suction fan 3, the No. 2 suction fan 15 and the suction pump are started. At this time, the multi-level suction mechanism 2 is used to realize the simultaneous suction of the smoke and dust in the upper, middle and lower layers of the steel pipe production workshop, with high suction efficiency and fast speed. After the smoke and dust enters the purification box 1, the filter plate in the circulation mechanism 5 is used for primary treatment, and with the coordinated use of the servo transverse movement module 51, the lifting clamping assembly 52 and the circulating filter assembly 53, the filter plate in the filter frame 532 is used in a circulating manner, thereby avoiding the problem of excessive use of a single filter plate leading to a decrease in filtering effect. Then the filter element 12 is used for secondary treatment. At the same time, when the circulation mechanism 5 is cyclically replaced, the linkage rod 62 and the mounting plate 632 thereon are moved horizontally to the left and right, and the rotating sleeve 635 and the annular brush 636 thereon are driven to move horizontally to the left and right. The annular brush 636 is used to clean the outside of the filter element 12 horizontally and reciprocatingly. Since the active gear 615 is meshed with the rack 611, the active gear 615 rotates simultaneously during the horizontal movement, thereby synchronously driving the dust removal and cleaning mechanism 6 to scrape and rotate the filter element 12 horizontally, and the cleaning effect is good, which effectively avoids the problem of clogging of the filter element 12. The gas filtered by the filter element 12 is ejected by the nozzle 14 and then enters the water tank 9 for adsorption, realizing the three-level treatment of the smoke. After further adsorption by the activated carbon adsorption box 8, it is discharged from the exhaust hole 4, realizing the multi-stage purification of the smoke in the steel pipe production workshop, and the purification effect is good.

[0052] The above-mentioned embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention.
