The invention relates to the technical field of dust removal in coal mine roadways, in particular to a movable dust removal and explosion-proof device for coal mine roadways, which includes a main line pipe, a branch line pipe and a suction head. One end is connected with a suction head, the shape of the suction head is a circular plate shell, and one end is integrally connected with a square shell. The inner cavity of the circular plate shell of the suction head is provided with an outer cylinder, a shaft and a blade plate, and the inner cavity of the outer cylinder is There is a movable sleeve with a shaft, and the fixed ring on the outer wall of the outer cylinder is provided with a number of uniformly distributed blade plates. The structure design of the present invention realizes that several suction heads perform suction work intermittently, that is, several suction heads perform suction work alternately. Here, it is enough to adjust the relative position of the propulsion plate and the intercepting device. Several suction heads are not inhaled at the same time, and low-pressure suction is needed in the main line pipe, which can drive the whole of the present invention and realize stable and efficient suction. Gas work, greatly saving energy loss.
Description
technical field [0001] The invention relates to the technical field of dust removal in coal mine roadways, in particular to a movable dust removal and explosion-proof device for coal mine roadways. Background technique [0002] In the coal mine roadway dust removal work in the prior art, the air suction device is installed in the coal mine roadway, and the exhaust work can be realized after extending to the outside through the air pipe. There are certain hidden dangers in this mode. The motor drives the suction device, and The motor and the suction device are fixed together and installed in the coal mine roadway. Once the motor rotates and generates sparks, it may cause a gas explosion in the coal mine roadway. [0003] If a coal mine roadway dust removal device can be invented, the motor and air pump can be placed outside, and the suction head can be placed in the coal mine roadway, and the problem can be solved. For this reason, we have provided a coal mine roadway with a ...
