Environment-friendly welding fume purification device for environmental protection

Abstract

The invention provides an environment-friendly welding fume purification device for environmental protection. The device comprises positioning insertion rings, an activated carbon adsorption net, a photocatalysis plate, an air filter net, a tightening fixing plate, a clamping groove plate, springs, lamp tube power connection plug bushes, ultraviolet lamp tubes and an insertion ring positioning supporting frame. A wind gathering cover is arranged at the top end of a settling box in a supporting communication mode, a purification box is welded to the top end of the wind gathering cover in a supporting communication mode, and an axial flow fan is arranged at the top end of the purification box through locking by screws. Four bent supporting legs are symmetrically welded at the bottom positions of the left and right side walls of the settling box in a supporting mode. Two fire-retardant boxes are respectively positioned between the supporting legs in the left group and between the supporting legs in the right group, and two rows of connecting supporting plates are symmetrically welded between the fire-retardant boxes and the two groups of supporting legs on the left side and the rightside of the fire-retardant boxes. By means of the arrangement of the photocatalysis plate, under triple filtration of the activated carbon adsorption net, the photocatalysis plate and the air filter net, harmful substances in welding fume are almost decomposed, adsorbed and exhausted, and therefore, the filtering effect of the device body is effectively improved.

Description

technical field [0001] The invention belongs to the technical field of welding fume purification devices, and more specifically relates to an environment-friendly welding fume purification device for environmental protection. Background technique [0002] In the welding workshop, various welding operations will produce a large amount of welding fumes. If the human body inhales welding fumes in large quantities or for a long time, it will seriously affect the health. Inhalation of welding fumes into the lungs will easily lead to lung diseases, and at the same time, it will irritate the eyes of workers. , affecting eyesight, working in a workshop full of welding fumes for a long time, causing great physical and mental harm to workers. When the concentration of welding fume in the welding workshop is too high, the visibility of the workshop will be affected, and safety accidents will easily occur. [0003] After searching, for example, the patent No. CN206862155U discloses a m...

Problems solved by technology

[0007] In order to solve the above technical problems, the present invention provides an environmentally friendly welding fume purification device for environmental protection, to solve the problem that the existing welding fume purification device has a small number of settling cavities in the process of flue gas circulation, which in turn causes damage to welding slag. The effect of sedimentation and separation is poor, and the operation of collecting, removing and dumping welding slag is also inconvenient. In addition, the overall purification of the device is poor due to the relatively simple means of filtration and purification.
