Abstract

The utility model relates to a device which can improve the working environment of welding workers, which is characterized in that a welding gun and a smoke suction pipe are designed as integration, and the welding smoke air can be purified with making use of the principle of static electricity aggregation filtering. The utility model has simple structure, small size, convenient maintenance and low cost of purifying components, and the purifying rate can reach 99.98%.

Description

Smoking welding gun clearing machine

The utility model relates to a kind of equipment of the welder's of improvement operating environment, and this equipment is mainly used in the clarifying smoke aspect of the artificial carbon-dioxide arc welding rifle in various welding place.

In many rivet welding manufacturings, weldering smoke pollution operating environment especially severe, personnel inhaled the air that the people is contained a large amount of manganese dirt for a long time around welding personnel reached, and the people who suffers from manganese dirt anthraco-silicosis is a lot.Survey formula through relevant department, in large-scale welding shop, the manganese dust content (is converted into MnO ₂) up to 2.0-2.9mg/m ³, regulation manganese dust content must not surpass 0.2mg/m in " industrial hygiene design standard) " ³For improving welder's operating environment, engineers and technicians develop multiple weldering cigarette cleaning equipment, take the weldering cigarette clearing machine of technology as the leading factor as forms such as: water curtain style, electrostatic, active carbon formula, filtering types.The higher equipment volume of purifying rate is huge, complex structure, and the fault rate height is controlled shortcomings such as cumbersome, so, be difficult to adapt to the mobility of welding gun.

The purpose of this utility model is exactly that to design a kind of welding gun and Smoking pipe be that the electrocoagulation work principle of filter that utilizes of one purifies the smoking welding gun clearing machine of welding place air, makes smoking effect improved, and device structure is simple, volume-diminished.

Smoking welding gun clearing machine described in the utility model is to constitute the smoking function by welding gun rifle head Smoking pipe, smoking pipeline, branch pipe tee connection.Constitute buffering area by entering the mouth district, electrostatic charge electrocoagulation district, Rose Box, powerful blower fan etc. partly constitute main frame.It is that Smoking pipe is fixed on the carbon-dioxide arc welding rifle; the other end links to each other with one-level smoking pipeline; link to each other with secondary smoking pipeline through threeway; the weldering cigarette enters in the clearing machine through this smoking pipeline; the weldering cigarette passes through the corona pole plate again, and collecting plate enters Rose Box, and flue dust is delayed in the Rose Box; clean air welds the purpose that cigarette purifies by outside the blower fan discharge machine thereby reach.

Smoking welding gun clearing machine described in the utility model, simple in structure, volume is little, and attended operation is easy, and the purifying part replacement cost is low, removes stage makeup and costume conveniently, guarantees to handle fume amount and efficient.Through environmental protection and labour department cleaned air passes is tested, purifying rate can reach 99.98%.
