Roller shutter dust catcher

Abstract

The invention relates to a roller shutter type dust collecting net device. The roller shutter type dust collecting net device comprises a frame body, a rotary shaft, a nylon net, a spraying pipe and a chain block, wherein the rotary shaft is installed between two supporting plates on the frame body, the nylon net is connected to the rotary shaft, the spraying pipe is fixed between the two supporting plates on the frame body, a water inlet connector and a spraying head are arranged on the spraying pipe, an installation plate is fixed to the outer side of the frame body, the chain block is installed on the outer side of the installation plate, and a rotary shaft of the chain block is connected with one end of the rotary shaft. In addition, the nylon net is coated with a dedusting agent. The roller shutter type dust collecting net device is reasonable in design, simple in structure, safe, reliable, easy and convenient to maintain, high in mechanical efficiency, small in hand chain pulling force, low in self weight, convenient to install and durable. Due to the arrangement of the spraying pipe, the nylon net and the dedusting agent, dust can be well prevented from exceeding the standard, a safe production environment is created for workers, and the labor intensity of workers is relieved.

Description

technical field [0001] The invention relates to the technical field of downhole dust prevention, in particular to a rolling shutter type dust catcher. Background technique [0002] The function of the dust catcher is to reduce the dust generated in the coal cutting process and prevent the dust from exceeding the standard. The dust catcher net in the tail lane of the fully mechanized mining face is often used poorly. In the past, it was made of door frame type, push-pull type, etc., and it was made of angle iron and square steel. Difficult to move and flawed in design. There are many problems in actual use. When transporting materials or getting in and out of the car, there is not much space, and the bearings on the runway are easily rusted due to moisture in the tail alley, and the activities are not flexible. Contents of the invention [0003] The object of the present invention is to provide a roller shutter type dust catcher device in order to solve the above-mentione...

Problems solved by technology

The dust catcher net in the tail lane of the fully mechanized mining face is often used poorly. In the past, it was made of door frame type, push-pull type, etc., and it was made of angle iron and square steel. Difficult to move, flawed in design

There are many problems in practical use. When transporting materials or getting in and out of the car, the space is not large, and the bearings on the runway are easily rusted due to moisture in the tail alley, and the movement is not flexible.
