Dust collection device for building site

Abstract

Provided is a dust collection device for a building site. The main content is that the device comprises nozzles, a hoop, a pressure resistant rubber water hose, a steel pipe, a rotating joint, nozzle supports, a ball valve, a pressure gauge, a multistage centrifugal pump, a motor, a water filter, a water tank, an elbow, a copper bush, an O-shaped seal ring, a straight pipe, a lock nut, and a stop screw. The device uses a tower crane on the building site to fix a pipeline on the standard knot of the tower crane. The pipeline is connected with a spray boom on the revolving support center of the tower crane through the rotating joint. The spray boom is fixed on a tower crane arm rack. The spray boom is uniformly provided with a plurality of nozzles. The nozzle supports are fixedly installed on the spray boom. The nozzles are fixed on the nozzle supports. Thus, the water of the multistage centrifugal pump can be sent to high altitude of tens of meters and even hundreds of meters, and through rotation of the tower crane, effect of large-area spraying and dust setting is achieved. The device is low in cost and easy in maintenance, and solves a problem of dusts of the building site.

Description

technical field [0001] The invention relates to the technical field of building environmental protection, in particular to a construction site dust removal device. Background technique [0002] With the continuous acceleration of urban modernization, a large number of construction sites inevitably appear in the city. Various construction sites have caused very bad impacts on the surrounding environment, and dust pollution is the first to bear the brunt. A large amount of dust will be generated in the construction site. If it is allowed to fly around, it will cover the whole city with a thick layer of dust; moreover, among these dusts, there are a large amount of substances harmful to human body, which will impact on the health of urban residents. [0003] In order to avoid these problems, in the prior art, a large amount of water spray devices are generally installed on the fixed buildings of the construction site or the surrounding ground, and the spray water of the water ...

Problems solved by technology

However, this method has the following disadvantages: firstly, the water spray device is fixed on the ground, the height of the sprayed water is not enough, and the range that can be controlled is not enough, so it is impossible to reduce the dust in a higher or larger range, and it cannot Work in windy and other weather; secondly, the water spray device fixed on the building is in a state of being unable to move, the height is fixed, the dust control range is fixed and cannot be adjusted, and it cannot handle the dust in all directions; finally, the amount of water sprayed Unable to adjust according to actual needs, resulting in a lot of waste of water
