Description

A dust removal device

technical field

The utility model relates to the technical field of dust removal equipment, in particular to a dust removal device.

Background technique

As we all know, construction refers to the production activities in the implementation stage of engineering construction. It is the construction process of various buildings. It can also be said to be the process of turning various lines on the design drawings into real objects at designated locations. Construction activities In the process, the staff often need to cut and build the aerated block with the cutting machine, and a large amount of dust will be generated in the process of cutting the aerated block; the current cutting machine is not convenient for dust removal in the process of cutting the aerated block, and the dust floats It is easy to endanger the health of the staff in the air. In order to provide occupational health protection for the staff, a dust removal device for the construction of the aerated block is needed.

After searching, the utility model patent with the Chinese patent number CN202220952603.1 discloses a construction dust removal device for occupational health protection, which includes an air duct and two dust removal boxes. Both sides of the air duct are fixedly connected to the dust removal boxes. The top of one side of the box is hinged with a sealed door, and the inside of the two dust removal boxes is equipped with a filter assembly and an exhaust fan. The two filter assemblies are respectively fixedly connected with the inner walls of the top of the two dust removal boxes. Move the dust removal box to the wheel, place the two dust removal boxes on both sides of the aerated block cutting machine, the air duct can be located at the top of the aerated block cutting machine, then step on the wheel brake of the universal wheel, lock the universal wheel, and pass the cutting When the machine cuts the air block, the staff turns on the exhaust fan switch, and the two exhaust fans can discharge the air inside the two dust removal boxes through the air outlet, so that the two dust removal boxes are in a negative pressure state, and cutting the air block produces The dust can be sucked into the air duct through the exhaust hood, and finally dispersed into the two dust removal boxes. When the air flows through the filter cloth, the filter cloth can filter the dust in the air flow, and the dust can stay in the dust removal box. Supporting the filter cloth can improve the bearing capacity of the filter cloth. The filter cloth is not easy to be damaged. The purified air can be discharged through the air outlet, avoiding the phenomenon of dust floating in the air and endangering the health of the staff. During the working process, the threaded rod passes through the The horizontal rod can limit the position of the exhaust hood, and the exhaust hood is not easy to shake horizontally. The friction between the nut and the threaded rod can support the horizontal rod, which can maintain the height of the exhaust hood. When the height of the exhaust hood needs to be adjusted, the staff turns the nut, the nut It can drive the horizontal rod up and down to adjust the height of the exhaust hood, which can be used with cutting machines of different heights. When dust needs to be cleaned, the staff can turn off the exhaust fan switch and open the airtight door to collect the dust collected inside the dust removal box. Dust cleaning, the number of aerated blocks required in the process of building construction is large, the time required to cut aerated blocks is relatively long, and the amount of dust generated in the process of cutting aerated blocks is also relatively More, the dust generated by cutting the aerated block is easy to be adsorbed on the filter, which is easy to cause the blockage of the filter. People need to clean the filter frequently in the process of cutting the aerated block, so it takes a certain amount of time , thereby reducing the cutting time of the aerated block and reducing the efficiency of cutting the aerated block.
