Dust-collecting and dust-falling device for building construction ground surface

Abstract

The invention discloses a dust-collecting and dust-falling device for a building construction ground surface. After dust is sucked into through a fan, cooperating with internal rainfall, dust fallingis conducted. The dust-collecting and dust-falling device is characterized in that inner sleeves are arranged inside outer sleeves, the inner sleeves are connected with one ends of the outer sleeves through square-to-round diameter variable tubes, the inner sleeves are circular tubes, and the outer sleeves are square tubes; one ends of the square-to-round diameter variable tubes are circular, theother ends of the square-to-round diameter variable tubes are square, and flow collecting cavities are formed between the outer walls of the square-to-round diameter variable tubes and the inner wallsof the outer sleeves; sealing rings are arranged on the inner walls of the inner sleeves, the inner sides of the sealing rings are arc-shaped surfaces, and the thicknesses of the sealing rings are gradually increased from the middle to the two sides; a hollow flow guiding frame is arranged on the inner walls of the other ends of the outer sleeves, mist spraying cavities are formed in the hollow flow guiding frame, one ends of water inlet tubes are arranged in the mist spraying cavities, and the other ends of the water inlet tubes penetrate through the hollow flow guiding frame; and a fixing sleeve is arranged in the middle position of the interior of the hollow flow guiding frame and is connected with the inner side of the hollow flow guiding frame through a honeycomb disc.

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
