Problems solved by technology
Such a large amount of high-concentration welding fume dust removal and purification treatment has become a big problem. Frequent replacement of filter media (filter or bag) for general-purpose dust collectors (filter or bag) not only consumes too much material and labor costs
More importantly, welding operations cannot be performed when replacing the filter medium (filter element or cloth bag), which greatly affects the production efficiency of the whole machine

The invention discloses a welding smoke water-bath purification device, which comprises a smoke collection hood, a smoke branch pipe, an adjusting valve, a gas collection tank, a circulation water pipe, a smoke main pipe, a purification water tank, a circulation water pump, an induced draught fan, and a purification tank assembly. The purification tank assembly comprises a water tank cover, a shower pipe, water tanks, air filtering mesh plates, a water injection port, a communication pipe, a liquid level meter, and a water discharge valve. Two water tanks are arranged on a left side and a right side separately; one air filtering mesh plate is horizontally arranged in each water tank; and two water tanks are connected by the communication pipe to form a U shape structure. The provided device can well purify high concentration welding smoke generated during the welding process. Compared with a bag type dust remover or a filter cylinder type dust remover, the time of stopping the device to change the filter materials is largely reduced, the human cost and filter material cost are reduced, and the equipment utilization efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of fume purification devices, in particular to a welding fume water bath purification device. Background technique [0002] Welding fume is caused by high temperature and ionization during arc heating, resulting in metal vaporization and ionization of metal dust, metal nitrogen oxide oxide particles, and nitrogen oxide gas. Contains heavy metals and toxic and harmful ingredients. Inhalation can cause serious bodily harm. Generally, the concentration of smoke in open space or single arc welding is not very high, and general-purpose dust collectors (filter type, bag type) are generally used for dust removal and purification treatment. High-concentration welding fume using a general-purpose dust collector (filter type, bag type) will block the filter medium very quickly, and the dust cleaning device will not work. The filter medium (filter element or cloth bag) should only be changed frequently. U-rib inner...
