Welding fume purification device facilitating circulation and replacement

Abstract

The invention relates to a welding fume purification device facilitating circulation and replacement. The welding fume purification device comprises a base, a suction hood, a suction arm, a purification pipe, a water drainage pipe, an exhaust pipe, a controller, a replacement mechanism and an unchoking mechanism; a gas guiding component, a support frame, a pressurizing mechanism and a dust filternet are arranged in the purification pipe; the unchoking mechanism comprises a water tank, a water injection pipe, a water pump and a water outlet pipe; the pressurizing mechanism comprises a pressurizing component, a pressurizing plate and two ventilation components; and the replacement mechanism comprises a replacement room, a sealing block, a sealing cover, a handle, a moving component and a pushing plate. According to the welding fume purification device facilitating circulation and replacement, through coordinate application of the unchoking mechanism and the pressurizing mechanism, waterflow is squeezed downwards, metal particles on the dust filter net are squeezed out, air circulation is ensured, in addition, activated carbon filter nets saturated through absorption in the purification pipe can be replaced in time through the replacement mechanism, the continuous purification capacity of the purification device to air is ensured, and the practicality of the purification deviceis improved.

Description

technical field [0001] The invention relates to the field of environmental protection equipment, in particular to a welding fume purification device which is convenient for circulation and replacement. Background technique [0002] Welding fume purifier is an industrial environmental protection equipment, which is specially designed for welding, cutting and grinding. It is a purification device designed to produce a large number of fine metal particles suspended in the air that are harmful to the human body. It is suitable for single and double stations. It has high purification efficiency, is light and flexible, and is equipped with a flexible suction arm. It can move flexibly in different working places and is easy to operate. , to protect the environment and protect the health of workers.

AI Technical Summary

Problems solved by technology

[0003] When the welding fume purifier is in use, the welding fume is sucked into the equipment mainly through the gravitational force of the fan, and the metal coarse dust particles are isolated through the filter element. After absorbing the harmful gas in the air through the activated carbon filter, the clean and harmless air is discharged. After long-term use, various particles are easy to accumulate in the mesh of the filter element, resulting in poor air circulation. Not only that, when using an activated carbon filter for purification, the activated carbon will reach saturation after a period of use. At this time, the equipment continues to operate, which is easy to cause The harmful gas adsorbed by activated carbon volatilizes, causing secondary pollution of the air and affecting the respiratory health of workers, and workers sometimes forget to replace the activated carbon filter due to negligence, which makes the equipment unable to purify the air at this time, reducing the existing The practicability of the welding fume purification device
