Portable high-negative pressure welding fume purifier

Abstract

The invention discloses a portable high-negative pressure welding fume purifier which comprises a shell, wherein the shell is internally provided with a high-efficiency filter device and a high-negative pressure air blower sequentially from front to back, and the shell comprises a front cover, a rear cover, an upper cover and a bottom plate; two sides of the upper cover downwards extend to be connected with the bottom plate; the front cover is provided with an air inlet, a pressure induction switch, a current induction switch and a speed regulating knob; the speed regulating knob controls the rotating speed of the high-negative pressure air blower, the pressure induction switch is connected with the high-efficiency filter device, and the current induction switch is communicated with the high-negative pressure air blower; the bottom plate is provided with a support pipe, and the support pipe is movably arranged on the lower side of the high-efficiency filter device; and the rear cover is provided with an air outlet and a waterproof connector, and the waterproof connector is communicated with a power supply and a current induction module. The portable high-negative pressure welding fume purifier disclosed by the invention is kept synchronous with the working state of a welder, has the advantages of working efficiency improvement, power supply saving and high automation degree and is more systematized in fume suction, flexible in movement and convenient to disassemble and maintain.

Description

technical field [0001] The invention relates to fume purification, in particular to a portable high negative pressure welding fume purifier. Background technique [0002] There is a lot of smoke and dust in welding, cutting, grinding and other mechanical processing workshops, and these smoke and dust often contain sparks. In order to avoid fires in the workshop and at the same time ensure the health of the operators in the workshop, smoke and dust purification equipment is usually installed in the workshop, and high negative pressure smoke and dust purifiers are the first choice. [0003] The filtration process of the high negative pressure dust purifier is divided into two stages, the first stage is the filtration of large particles of sparks, and the second stage is the filtration of fine dust. The smoke and dust generated during welding, cutting and grinding process enters the high negative pressure smoke and dust purifier through the suction pipe under the action of hig...
