Simple water curtain dust-settling apparatus

Abstract

A simple water curtain dust-settling apparatus comprises two bases, the lower end of each base is fitted with a plurality of universal wheels, the bases are hinged to lower ends of two support frames, the upper ends of the two support frames are hinged to two ends of a connecting frame, respectively, the connecting frame is an arc frame having a downward opening, the distance between two ends of the connecting frame is less than that between the two bases, each of the support frame and the connecting frame is fitted with a plurality of holding boards that are provided with a water outlet pipe, one end of the water outlet pipe is connected with a water pump and a water supply, the other end of the water outlet pipe is closed, and a plurality of nozzles are evenly disposed on the water outlet pipe. The simple water curtain dust-settling apparatus has the advantages that in the apparatus, the two support frames borne by the bases and the connecting frame form an arch frame, the arch frame may be adjusted according to the size of a tunnel so that the arch frame is as close to the edge of the tunnel as possible without using a tunnel rail, thus using small floor area and facilitating passage of construction equipment and staff, the water outlet pipe on the arch frame sprays along the edge of the tunnel to settle dust, and spray area is large so that dust settling efficiency is high.

Description

technical field [0001] The invention relates to a dust suppressor, in particular to a simple water curtain dust suppressor. Background technique [0002] During the construction of the tunnel, due to inconvenient ventilation, the dust generated during drilling and blasting, ballasting, ballasting, and spraying anchors is diffuse. The existing dust suppression equipment is generally carried by a trolley to carry a mining automatic sprayer to spray water along the track in the tunnel to reduce dust. However, this kind of equipment occupies the track in the tunnel, occupies a large area, makes it inconvenient for personnel and vehicles to pass through, and cannot carry out construction during the dust reduction process. Moreover, this kind of equipment has a small dust reduction area and low dust reduction efficiency. Contents of the invention [0003] In order to solve the above problems, the dust suppression device can be constructed during the dust suppression process with...
