Technical Field

[0001] The utility model belongs to the technical field of fume treatment, and particularly relates to a welding fume dust collector. Background Art

[0002] A welding fume dust collector, also known as a welding fume suction cleaner, absorbs and treats waste residues and toxic and harmful gases generated during operations such as electric welding, shielded metal arc welding, and gas tungsten arc welding through a filtering purification method. The welding fume dust collector can reduce gas pollution, reduce the health hazards of harmful substances to operating workers, and prevent the occurrence of occupational diseases such as pneumoconiosis.

After long-term use, the filter element becomes blocked, and it is difficult to clean the filter element. The filter element needs to be replaced at regular intervals, resulting in too high costs. Second, the filtering of welding fume is not thorough enough, and the treated welding fume does not meet the standards and still poses a hazard to workers. Summary of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a welding fume dust collector, which includes a box body.

[0005] The box body includes a first partition board, a second partition board, a first air outlet and a first air inlet. The first partition board is vertically arranged in the box body, dividing the box body into a first chamber and a second filtering chamber. The second partition board is horizontally arranged in the first chamber, dividing the first chamber into a third filtering chamber and a first filtering chamber. The first air outlet is arranged on the side wall of the third filtering chamber and is communicated with the atmosphere through an exhaust pipe. The first air inlet is arranged on the side wall of the first filtering chamber, and an air inlet hopper is connected to the outside of the first air inlet through a universal pipe.

Inside the filtering tower, there are successively arranged a cavity, a filter plate fixedly connected to the filtering tower and uniformly provided with small holes, a first filter cloth, activated carbon adsorption particles, and a second filter cloth from bottom to top. A hydraulic cylinder is arranged at the bottom of the filtering tower, and the fixed end of the hydraulic cylinder is fixedly connected to the inner bottom surface of the second filtering chamber. The telescopic end of the hydraulic cylinder penetrates into the bottom of the filtering tower and is slidably and sealingly connected to the filtering tower. The telescopic end of the hydraulic cylinder is fixedly connected with a piston block matching the cross-sectional shape of the filtering tower.

[0008] An air inlet two is provided on the side wall of the filtration tower below the filter plate, and an air outlet two is provided at the top of the filtration tower; the air inlet two is connected to the first channel through an air inlet pipe, and a one-way air inlet valve is provided on the air inlet pipe. The air outlet two is connected to the second channel through an air outlet pipe, and a one-way air outlet valve is provided on the air outlet pipe.

In addition, the universal pipes or filter plates not defined in the present utility model all adopt conventional technical means in the art.

[0017] The working principle of the present utility model is that the device inhales and discharges air through the telescopic movement of the hydraulic cylinder.
