Welding fume purification and dust removal device used in tank body

Abstract

The invention discloses a welding fume purification and dust removal device used in a tank body. The device comprises a filter cartridge type dust remover, a telescopic hose, a gas collecting hood anda plurality of fixing devices capable of fixing the telescopic hose in the tank body and moving, one end of the telescopic hose is connected with the filter cartridge type dust remover, the other endis connected with the gas collecting hood, can extend into the tank body, is fixed at one end of each fixing device in a suspended manner and can correspond the gas collecting hood to a welding pointinside the tank body, and the other end of each fixing device can be fixed with the inner wall of the tank body. Compared with the prior art, the gas collecting hood can be moved and fixed to the position corresponding to a welding spot at any time in the tank body internal welding process, smoke dust is absorbed from the source, smoke dust accumulation in the tank body is avoided, and the body health of operators is prevented from being affected. An alarm device is arranged, and the situation that the operators cannot call for help when encountering dangers during internal operation is avoided. A gas detection device and a temperature detection device are arranged, so that the environment change in the tank body can be detected in real time, and the danger of operators is avoided.

Description

technical field [0001] The invention relates to a welding fume purification and dedusting device used inside a tank body. Background technique [0002] For large tanks, it is necessary to carry out longitudinal seam welding on the inside of the tank. During the welding process, people need to enter the inside of the tank for welding. Since the tank to be welded is in a closed or semi-closed space, the smoke generated cannot be discharged, especially Especially when working in a limited space, even continuous blowing in the tank cannot discharge the smoke and dust generated during the welding process in time, resulting in the accumulation of smoke and dust in the tank, which seriously affects the health of the workers. Contents of the invention [0003] In view of the above, the present invention provides a welding fume purification and dust removal device used inside the tank to solve at least one problem in the above-mentioned prior art. [0004] In order to solve the pr...
