Welding flux atmosphere collecting and filtering device

Abstract

The invention discloses a welding flux atmosphere collecting and filtering device which is convenient to move and install. The height and the angle can be adjusted so as to adapt to the welding degassing device with different angles; the device is characterized in that a base is of an isosceles triangle structure; the bottom edge of the base is an arc-shaped edge; an air pump mounting cavity is formed in the base and is arranged in the air pump mounting cavity; a switch for controlling the air pump to start and stop is arranged on the base; a hinge lug is arranged on the base; one end of the lower support arm is hinged with the hinge lug; fixing is achieved through tightening bolts, one end of the upper supporting arm is hinged to the other end of the lower supporting arm, which are fixedthrough tightening bolts; one end of the hinge rod is hinged to the other end of the upper supporting arm, which are fixed through a tightening bolt; one end of the connecting pipe is connected with the hinge rod, one end of the main pipe is sleeved with the other end of the connecting pipe, the filter element is arranged in the main pipe and attached to the bottom of the main pipe, and a plurality of air exhaust holes are formed in the bottom of the main pipe at equal intervals.

Description

technical field [0001] The invention relates to a welding flux atmosphere collecting and filtering device, which relates to a device for collecting and filtering fume generated by welding rod melting during component welding, and belongs to the field of mechanical processing. It particularly relates to a device that is convenient for mobile installation and can be adjusted in height and angle to adapt to welding degassing at different angles. Background technique [0002] At present, in the process of industrial production and processing, it is often necessary to connect two components by welding, through a welding machine and an electrode. After the electrode is melted, the coating on the surface will generate a large amount of smoke, which is used to change the atmosphere and avoid melting. The metal in the pool is oxidized, and a large amount of smoke affects the operator and causes visual obstruction. Therefore, it is necessary to deal with the smoke. The existing gas ex...

Problems solved by technology

[0002] At present, in the process of industrial production and processing, it is often necessary to connect two components by welding, through a welding machine and an electrode. After the electrode is melted, the coating on the surface will generate a large amount of smoke, which is used to change the atmosphere and avoid melting. The metal in the pool is oxidized, and a large amount of smoke affects the operator and causes visual obstruction. Therefore, it is necessary to deal with the smoke. The existing gas extraction structure is installed on the electrode side to extract the generated smoke, but Its position is fixed, and it is located on one side of the arc, which may easily lead to unstable arc. Other degassing devices have complex structures and are inconvenient to use and adjust.

[0003] Publication number CN201950319U discloses a smoke extraction device for extracting welding smoke, including a welding device and an exhaust pipe connected to the smoke machine. The first end of the smoke exhaust pipe is provided with a smoke port, and the smoke port extends to the side of the welding part of the welding device. The exhaust structure in this device is located on the side of the welding structure, which is prone to arc instability, and the integrated structure , inconvenient to use when moving

[0004] Publication number CN207747009U discloses a smoke-free welding training platform, which includes a pillar, a hood, a welding station, and a drawer. A top plate is provided on one side of the top of the pillar, and an integrated light groove is arranged on the lower side of the top plate. The integrated light groove The lower side is provided with a lamp tube, the two sides of the integrated light groove are provided with light collecting plates, the top of the pillar is far away from the side of the top plate is provided with a hanging plate, the hanging plate is provided with a hanging hole, and the middle part of the pillar is far away from the The smoker is installed on one side of the hanging board, and the tool table is installed on the lower side of the smoker. This device has a complex structure and is not suitable for mobile use in the workshop, and is not suitable for welding at different angles, and the degassing effect is poor.
