Description

Technical Field

[0001] The utility model relates to the technical field of welding smoke purifiers, in particular to an air outlet mechanism of a welding smoke purifier. Background Art

[0002] Welding fume purifier, also called welding fume hood, electric welding dust collector, electric welding machine protective cover, etc., is used to purify smoke and dust generated during welding, polishing, cutting, grinding and other processes, as well as the recovery of rare metals and precious materials. It can purify a large number of fine metal particles suspended in the air that are harmful to the human body. It is an essential product to protect the health and safety of welders.

[0003] After the welding smoke purifier has been working for a long time, a lot of dust will adhere to the internal filter, and the smoke sucked in cannot be completely purified, thereby reducing the quality of emissions. Therefore, an exhaust mechanism of the welding smoke purifier is proposed to facilitate workers to replace the filter, ensure sufficient purification, and thus improve the quality of emitted air. Utility Model Content

[0006] A filter is arranged in the body of the purifier, a connecting plate is arranged at the bottom of the filter, a connecting pipe is arranged at the bottom of the connecting plate, and an exhaust fan is arranged at one end of the connecting pipe.

[0007] By adopting the above technical solution, smoke and dust are sucked into the purifier body through the exhaust fan through the pipeline and the dust collection arm;

[0008] The dust in the purifier body is absorbed by the adsorption cotton, and the dust in the purifier body and the dust in the smoke, lint and other foreign matter can be filtered together, and then the filter at the air outlet will filter them for the second time, and then the bolts are regularly removed to replace the adsorption cotton to achieve the purification effect;

[0009] When the exhaust fan draws smoke and dust into the purifier body, the larger dust in the smoke is filtered out through the adsorption cotton and filter, and then filtered through the filter for a second time before being discharged. The filter is regularly replaced to improve the quality of the discharged air.

[0010] Pushing the brakeable roller can drive the purifier body to move.

[0011] Specifically, the top of the air inlet is fixed to the dust suction arm by bolts, and the bottom of the dust suction arm is fixed to the dust suction cover by bolts.

[0012] By adopting the above technical solution, the smoke generated during welding can be centrally sucked into the purifier body by using the exhaust fan through the pipeline in conjunction with the dust suction arm and the dust suction hood.

[0013] Specifically, one end of the air outlet is fixed to a connecting pipe by bolts, one end of the connecting pipe is provided with a circular connecting pipe, a mounting groove is opened in the connecting pipe, and a filter sheet is fixed in the mounting groove by bolts.

[0014] By adopting the above technical solution, the smoke and dust are sucked into the purifier body by using an exhaust fan in conjunction with a pipe. The filter screen filters the larger dust in the smoke, and then passes through the filter screen for secondary filtration before being discharged, thereby improving the air quality.

[0015] Specifically, the filter is connected to the adsorbent cotton via screws, the dust collection arm passes through the adsorbent cotton, and the bottom of the filter passes through a reserved hole on the top surface of the connecting plate via a pipe and is connected to the connecting pipe.

[0017] By adopting the above technical solution, the smoke and dust are sucked into the purifier body through the exhaust fan through the pipeline in conjunction with the dust collection arm. While the dust in the purifier body itself is adsorbed by the adsorption cotton, the dust sucked into the purifier body and the dust in the smoke, the lint and other foreign matters can be filtered together, and then filtered for the second time by the filter at the air outlet, and the bolts are regularly dismantled and replaced.

[0018] Specifically, a bottom plate is provided at the bottom of the purifier body, and brakeable rollers are fixed around the bottom of the bottom plate by bolts.

[0019] By adopting the above technical solution, the purifier body can be driven to move by pushing the brakeable roller.
