Description

Technical Field

[0001] The utility model relates to auxiliary equipment for manufacturing steel structures, and more specifically to an integrated welding fume collection and processing system. Background Art

[0002] Welding is the main process for manufacturing steel structures in large-scale heavy industries. The welding process will produce a large amount of smoke and dust, the main components of which include iron oxides, copper oxides, chromium oxides, nitrogen oxides, carbon monoxide, etc. If not collected and treated in time, it will seriously affect human health and cause diseases such as pneumoconiosis.

[0003] At present, the collection and treatment of welding fume in large-scale heavy industry is mainly carried out by two methods: distributed suction arm and high negative pressure integrated welding gun. Among them, the distributed suction arm is suitable for the scene of dispersed welding operation points, and is mainly used for large component welding operation. It is generally installed on the column of the workshop. By adjusting the angle of each joint, the suction port of the suction arm is suspended just above the welding molten pool, so as to collect and treat the welding fume. However, due to the large working radius of the distributed suction arm, it is easy to form negotiations with the adjacent suction arm. Therefore, the welding operation points need to be dispersed in the scene of using the distributed suction arm, which is not suitable for batch welding of small workpieces, and the suction port needs to be adjusted in time to be just above the molten pool during use, which affects the construction of welding operators; the other method is a high negative pressure integrated welding gun, which mainly has a high negative pressure suction port at the nozzle of the welding gun, and can collect the welding fume as soon as it is generated from the molten pool. However, since the high negative pressure suction port is integrated at the front end of the welding gun, the protective gas protection molten pool is affected, the weld quality is reduced, and the weight of the welding gun increases sharply. When absorbing welding fume, heat is easily accumulated at the handle, which greatly affects the operation of welding operators. Utility Model Content

[0025] In order to better understand the above technical solution of the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0026] Combination Figure 1 As shown, the utility model provides an integrated welding fume collection and processing system, which includes an arc protection isolation cover 1, a welding fume processing unit 2, a main structure frame 3, an air suction cover 4 and a fume collection pipe 5.

[0027] The arc-proof isolation cover 1 is arranged on the main structural frame 3 to form an independent closed space, and the welding smoke generated cannot float out of the closed space.

[0028] There are multiple air suction hoods 4, all of which are arranged on the top of the main structural frame 3 and are connected to the top of the enclosed space.

[0029] The smoke collection duct 8 is located on the top of the main structural frame 3 and is connected to the plurality of suction hoods 4 .

[0030] The welding fume processing unit 2 is arranged at the top of the main structure frame 3 near the end position and is connected to the fume collecting pipe.

[0031] The suction hoods 4 are arranged in an even number, divided into two rows and symmetrically arranged on both sides of the smoke collection pipe 8.

[0032] The suction hood 4 is arranged in a pyramid shape, and the top thereof is connected to the side of the smoke collecting duct 8 through the duct 5 .

[0033] Combination Figure 2 As shown, the welding fume treatment unit 2 includes a box body 9, and a filter cartridge 6 and an air compressor 7 installed in the box body 9. A plurality of filter cartridges 6 are provided, which are divided into two rows and are installed symmetrically in pairs.

[0034] One end of the smoke collecting pipe 8 is connected to the box body 9, and the other end is a closed end.

[0035] The box body 9 is provided with a door panel 10 for facilitating replacement of the filter cartridge 6 or maintenance of the filter cartridge 6 and the air compressor 7 .

[0036] Combination Figure 3 As shown, the main structure frame 3 is a rectangular frame structure.

[0037] The arc-proof isolation cover 1 is composed of four arc-proof isolation plates, and the four arc-proof isolation plates are respectively installed on four side surfaces of the main structure frame 3.

[0038] A plurality of crisscross connecting rods 11 are arranged on the top of the main structural frame 3 to form a plurality of mounting positions 12 adapted to the air suction hoods 4 .

[0039] When welding is in progress, the welding smoke generated gradually drifts from the molten pool to the top of the arc-proof isolation cover 1 in the integrated welding smoke collection and treatment system of the utility model, and the welding smoke is gathered by the pyramid structure of the suction hood 4 and flows through its opening to the smoke collection pipe 8. The welding smoke treatment unit 2 continuously draws air through the air compressor 7 to form a negative pressure space, and the welding smoke flows in the smoke collection pipe 8 to the filter cartridge 6 of the welding smoke treatment unit 2, and is finally adsorbed on the surface of the filter cartridge 6. The purified gas is discharged through the air compressor 7, thereby completing the control, collection and treatment of the welding smoke.

[0040] When multiple welding operation points are working simultaneously inside the integrated welding fume collection and treatment system of the utility model, the arc-proof isolation cover 1 isolates the welding operation area from the non-operation area, blocks the arc, and protects the occupational health of personnel in the non-operation area.

[0041] The utility model integrated welding fume collection and treatment system is used as follows:

[0042] 1) Arrange welding operation points in the integrated welding fume collection and treatment system of the utility model;

[0043] 2) Turn on the power of the welding fume treatment unit 2, and the suction function starts to operate;

[0044] 3) The arc-proof isolation cover 1 is naturally placed vertically on the ground to start welding operation. The arc-proof isolation cover 1 prevents welding smoke from escaping from the system and prevents the welding arc from affecting the occupational health of personnel in non-operating areas;

[0045] 4) The welding fume passes through the suction hood 4, along the fume collection pipe 8, and is filtered by the internal filter cartridge 6 under the action of the suction of the fume treatment unit 2, and then discharged through the air compressor 7, completing the control, collection and treatment of the welding fume.
