Air filter machine special for electric welding

Abstract

The invention provides an air filter used in electric welding, substantially comprising a cabinet with a through opening at the top to connect an aspiration channel and an upper chamber and a lower chamber in the cabinet, while the upper chamber is communicated with the top through opening, a spark ash baffle device and a movable filter cloth respectively mounted at upper and lower sides inside. The movable filter cloth is provided with a filter cloth rotating some degree while the lower chamber is mounted with a blower inside and an extraction filter device outside to communicate with the lower chamber, to absorb the object air via the aspiration channel when the blower operates, to pass through the spark ash baffle device, the movable filter cloth, the blower and the extraction filter device to be discharge, to baffle the spark ash and filter air effectively.

Description

technical field [0001] The present invention is related to an air filter device, more specifically, it refers to a special air filter for electric welding. Background technique [0002] Many factories, including common metal welding factories such as argon welding, electric welding and heat treatment, are prone to produce welding fume during electric welding operations. The welding fume often contains heavy metal volatiles such as lead, cadmium, manganese, nickel and chromium. Therefore, When electric welders are exposed to the working environment of welding fume for a long time, they will inhale too much heavy metal in welding fume, which will cause various occupational diseases, such as fume fever, zinc cold, brass cold, asthma (nickel poisoning), Parkinson's disease (manganese poisoning), lung cancer (chromium oxide poisoning), etc. have seriously endangered the health of the body, and in order to reduce the risk of health that may be caused by high exposure to heavy meta...

Problems solved by technology

[0003] However, many working environments are limited by buildings, and it is difficult to achieve good ventilation effects. In addition, general ventilation equipment does not have air filtering function. Simply exhausting welding fumes will also cause welding fumes to scurry around, endangering the health of others. , so its effect is not good; secondly, although wearing respiratory protective equipment can prevent welding workers from inhaling the heavy metals contained in welding fume, it does not help others who are not wearing respiratory protective equipment around them, and wearing Wearing respiratory protective equipment is likely to affect the welding process and welding quality, and it is not an effective method; moreover, some factories use industrial air filtration equipment for air filtration, but the industrial air filtration equipment is usually directly connected with one or more The filter screen is used for filtering. Because a lot of oil and impurities are produced in the electric welding operation, the filter screen is often blocked by oil and impurities, and the filter screen must be replaced or cleaned frequently. It is quite inconvenient to use, and it is not replaced in time if neglect or cleaning, the air filtration effect will be greatly reduced. In addition, since most of the industrial air filtration equipment does not have a structural design that can block the inhalation of spark ash, once the spark ash is sucked into the equipment with the air, it will There is a risk of fire and combustion, or even gas explosion, so how to effectively solve the above problems is indeed necessary
