A primary effect preconditioner

Abstract

The invention discloses a primary effect preprocessor, which comprises a casing, on which an air inlet and an air outlet are arranged, and between the air inlet and the air outlet are sequentially provided with spiral wind guide blades, The blower and the blower, the casing, the windshield and the blower are combined to form a gas flow channel. After the smoke gas enters from the air inlet, the large particles in the smoke are accelerated by the wind guide blades, and under the action of centrifugal force, Rotating in the gas flow channel, the deceleration of the inner wall of the gas flow channel and the turning points makes the large particles decelerate and fall into the ash hopper below the casing to complete the filtration process. The present invention utilizes the characteristics of centrifugal action With the design of the gas flow channel to filter the large particles in the dust, the structure is simple and the efficiency is high.

Description

technical field [0001] The invention relates to a filter device, in particular to an initial effect preprocessor for filtering welding smoke. Background technique [0002] At present, people are becoming more and more aware of the harm of smoke generated during welding to the human body. During welding, arc discharge generates high temperature and produces a large amount of smoke while melting electrodes and weldments. These smoke contains a large amount of manganese, copper, Hazardous heavy metal substances such as ferric oxide, workers working in such an environment for a long time will cause pulmonary fibrosis. Therefore, many factories have installed primary effect preprocessors for dust removal, and welding fume contains large particles. With Mars, the general primary effect preprocessor cannot handle effectively and safely, therefore, the technical solution of the present invention arises at the historic moment. Contents of the invention [0003] In order to overcom...

[0002] At present, people are becoming more and more aware of the harm of smoke and dust generated during welding to the human body. During welding, arc discharge generates high temperature and produces a large amount of smoke and dust while melting electrodes and weldments. These smoke and dust contain a large amount of manganese, copper, Heavy metal harmful substances such as ferric oxide, workers working in this environment for a long time will cause pulmonary fibrosis. Therefore, many factories have installed primary effect preprocessors for dust removal, and welding fume contains large particles. With Mars, the general primary effect preprocessor cannot handle effectively and safely, therefore, the technical solution of the present invention emerges at the historic moment
