A dust collection and dedusting device for building construction ground

Abstract

The invention discloses a ground dust collection and dedusting device for building construction, which discloses a device for dedusting dust by cooperating with internal precipitation after the dust is inhaled by a fan. It is characterized in that the inner sleeve is placed in the outer sleeve, and is connected with one end of the outer sleeve through a square-circle reducing tube, the inner sleeve is a circular tube, the outer sleeve is a square tube, and one end of the square-circle reducing tube It is circular, and the other end is square. A manifold is placed between the outer wall of the square-circle reducing tube and the inner wall of the outer sleeve, and the sealing ring is placed on the inner wall of the inner sleeve. The inner side of the sealing ring is an arc surface, and The thickness gradually increases from the middle to both sides. The hollow guide frame is placed on the inner wall of the other end of the outer casing. The hollow guide frame has a built-in spray chamber. One end of the water inlet pipe is placed in the spray chamber, and the other end passes through the hollow guide frame. , the fixed sleeve is placed in the middle of the hollow guide frame, and is connected with the inner side of the hollow guide frame through the honeycomb plate.

Description

technical field [0001] The invention relates to a ground dust collection and dedusting device for building construction, which relates to a device for absorbing and dedusting ground dust collected on a construction site during building construction, and belongs to the field of building construction. In particular, it relates to a device for inhaling dust through a blower fan and coordinating with internal precipitation for dust suppression. Background technique [0002] At present, the dust accumulation in the construction site is serious. During the construction process, a large amount of dust will be raised and mixed in the air. With the increase of the dust concentration, the working environment of the construction workers is harsh, and respiratory diseases are prone to occur. When the concentration reaches a certain Explosion will also occur when the value is high. The traditional method is to reduce dust by sprinkling water. The dust is adsorbed by water on the ground t...

Problems solved by technology

[0004] Publication number CN205549857U discloses a ground dust removal device for a construction site, including a car body, an activated carbon filter, a dust extractor, and a sprayer. A push rod is installed on one side of the car body, and a handle is provided on the push rod. A solar panel is installed above the car body, an air outlet pipe is arranged above the car body, an automatic controller is installed on one side of the air outlet pipe, an ash discharge pipe is arranged under one side of the car body, and the ash discharge pipe An ash discharge switch is installed above the pipe, a wheel is installed on the lower side of the car body, a dust sweeping roller is installed in the middle of the lower part of the car body, and an ash collecting hopper is arranged on one side of the ash sweeping roller, and the ash collecting hopper There is a rubber pad at the bottom, and universal wheels are installed on the other side of the car body. This device combines water sprinkling and dust collection, but when sprinkling water, it will also cause the construction site to be muddy. When the indoor dust concentration is high, it will cause explosions and other situations, and there are dead spots in the moving path of the trolley, and the position close to the corner cannot be cleaned
