Industrial indoor welding dust-collecting device

Abstract

The invention discloses an industrial indoor welding dust-collecting device, comprising a box, a first support post, a second support post and a bottom plate. The box includes an intake port, an exhaust port, a filter chamber and a dust-collecting bucket; the filter chamber is communicated with the intake port; the filter chamber is releasably connected with the dust-collecting bucket; a suction fan is arranged below the dust-collecting bucket; the box is connected with the first support post via a driving mechanism mounted on the first support post; the driving mechanism includes a motor, a speed changer, a crankshaft, a bearing block and a transmission link; an output shaft of the motor is coaxially connected to one end of the crankshaft; the other end of the crankshaft is fitted in thebearing block; two ends of the transmission link are hinged to a round hole in a box lug and an eccentric segment of the crankshaft; the other side of the box is connected with the second support postvia a spring. The support posts and the driving mechanism allow surplus welding dust, attaching to the sidewall of the filter chamber during working of the device herein, to be shaken into the dust-collecting bucket, so that the service life of an activated carbon net is extended.

Description

technical field [0001] The invention relates to a welding fume dust collection device, which belongs to the technical field of industrial welding dust collection. Background technique [0002] Welding is a process that uses electric energy to heat the metal to be welded locally to a liquid state or close to a liquid state, so that it can be combined to form a firm non-detachable joint. The welding rod is melted at high temperature to reach the boiling point, and partly produces high-temperature steam. As soon as this high-temperature steam leaves the high-temperature zone of the arc, it is rapidly oxidized and condensed into fine solid dispersed particles, which are suspended in the air and form welding fumes. [0003] When the concentration of welding fume in an industrial welding workshop reaches a certain level, it will greatly affect the life and health of the operators; because the particle diameter of welding fume is very small, it will be immersed in the deep part of...

AI Technical Summary

Problems solved by technology

[0003] When the concentration of welding fume in an industrial welding workshop reaches a certain level, it will greatly affect the life and health of the operators; because the particle diameter of welding fume is very small, it will be immersed in the deep part of the lungs and deposited if it is dissolved. The blood causes poisoning, so it is very harmful

[0004] The efficiency of the dust collection device in the prior art is not high. In order to drop the dust attached to the dust collection equipment, it often needs to be beaten and shaken. There are many additional equipment, the dust collection effect is not good, and the volume is large and inconvenient to use.
