Description

Technical Field

[0001] This utility model relates to the technical field of devices for steel welding, and in particular to a dust collector for steel welding. Background Technology

[0002] Steel welding fume collectors are industrial environmental protection devices specifically designed for capturing, filtering, and purifying the fume pollutants generated during the welding process. Their core applications cover various steel welding processes such as electric arc welding, gas shielded welding, and submerged arc welding, and they are widely applicable to welding stations in industries such as machinery manufacturing, steel structure processing, and shipbuilding.

[0003] Existing steel welding fume collectors generally employ a basic structural framework of "suction arm + air duct + filter chamber + dust collection box + fan". In the fume collection stage, a single-section or retractable suction arm is typically used, with a fixed suction hood aimed at the welding pollution source. The filtration system usually employs a multi-stage filtration mode, and the cleaning method mainly relies on pulse-type automatic cleaning or manual disassembly and cleaning.

[0004] However, existing fume collectors for steel welding still have significant technical problems: the size of the air inlet is fixed, making it impossible to flexibly adjust the size and suction power according to the needs of the welding scene; the filter plate disassembly and assembly process is cumbersome, requiring the use of professional tools to gradually disassemble the fixed structure; traditional pulse cleaning relies on the back-blowing force of the airflow, which is difficult to completely remove stubborn dust attached to the surface of the filter element, and the multi-part fixing method of the dust collection box makes it necessary to disassemble the clips or bolts one by one when cleaning the dust, which is a cumbersome disassembly and assembly process. Therefore, it is necessary to develop a fume collector for steel welding to solve the pain points of the existing technology. Utility Model Content

A pulse valve is provided on the outer ring of the blowpipe 36. One end of the blowpipe 36 passes through and is fixedly connected to the top of the box 1. When the air compressor 35 is started, the compressed gas is blown onto the filter plate 13 through the blowpipe 36 to blow away the loose dust.

[0022] Working principle: After moving the equipment to the target welding position using the handrail on one side of the housing 1 and the omnidirectional brake wheels at the four corners of the bottom, the exhaust fan 34 is started. The fumes generated during the welding process are collected by the fume hood 12 under the negative pressure of the exhaust fan 34 and then sucked into the air inlet 3. They are then transported into the housing 1 through the telescopic hose 2. After entering the housing 1, the fumes are filtered through three layers of filter plates 13 and then discharged. When it is necessary to adapt to different scenarios, the electric push rod 11 is activated: its output end extends and retracts, which drives the first fixed frame 5 connected to it to rotate around the air inlet 3. This causes the rotating ring 4 to rotate synchronously inside the air inlet 3. The regular hexagonal guide groove at one end of the rotating ring 4 generates a driving force on the connecting column 9, causing the connecting column 9 to slide along the evenly distributed guide grooves on the guide ring 10, thereby driving multiple sealing plates 8 to expand or retract synchronously. When the sealing plate 8 is retracted, the opening area of ​​the air intake decreases, achieving concentrated adsorption of small-area dust; when the sealing plate 8 is unfolded, the opening area of ​​the air intake increases, achieving comprehensive coverage of large-area dust. When the filter plate 13 needs to be cleaned or replaced, the operator pulls the handle at the top of the connecting plate 16 upwards. The second magnetic blocks 15 at both ends of the connecting plate 16 will disengage from the first magnetic blocks 14 at both ends of the top of the housing 1, allowing the filter plate 13 to be directly pulled out of the housing 1 without any tools. When stubborn dust adheres to the surface of the filter plate 13, causing a decrease in suction, the servo motor 28 is activated, and its output end drives the left lead screw 18 to rotate. The left lead screw 18 drives the middle lead screw 18 to rotate synchronously through the first synchronous pulley 24 and the first synchronous belt 25 at the bottom. The middle lead screw 18 then drives the right lead screw 18 to rotate synchronously through the second synchronous pulley 26 and the second synchronous belt 27 at the top, achieving synchronous rotation of the three lead screws 18. When the lead screw 18 rotates, the nut pair 19 threadedly connected to it slides along the sliding groove 21 at the top of the support frame 17. As the nut assembly 19 slides down, it drives the sliding column 22 and brush 23 to move up and down synchronously via the fixing plate 20. The brush 23 contacts one side of the filter plate 13, scraping away stubborn dust on the surface and loosening it. Then, the air compressor 35 is started, and compressed gas is delivered to the inside of the housing 1 through the blowpipe 36. The pulse valve on the outer ring of the blowpipe 36 controls the blowing rhythm, and the compressed gas is evenly sprayed onto the surface of the filter plate 13, completely blowing away the loosened dust and residual fine dust from the filter plate 13 and cleaning up the fallen powder. Dust falls into drawer 29 at the other end of the box 1 under gravity, achieving centralized collection; when drawer 29 needs to be cleaned, the operator slides the sliding blocks 32 on both sides of the fixing block 30 outward, the tension spring 31 is stretched, the pressure plate 33 fixedly connected to the sliding block 32 disengages from the drawer 29, releasing the limitation on the drawer 29, and it can be pulled out for cleaning through the handle at one end of the drawer 29; after cleaning, the drawer 29 is reset, the sliding block 32 is released, the tension spring 31 resets and drives the pressure plate 33 to press the drawer 29 again.
