Embodiment Construction
[0024] The technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only a part of the embodiments of the present disclosure, but not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present disclosure.
[0025] like Figure 1-2 As shown, an air curtain dust-removing device for a shuttle car in a tunneling face includes a shuttle car 2, and an air curtain generating device is arranged on the upper part of the shuttle car. The device 1 is connected with the high-pressure air pipe 13 through the high-pressure rubber pipe 4 in the outlet section;
[0026] The air flow diffuser 1 is provided with a multi-layer air guide plate 14 near...

The present disclosure discloses an air curtain dust-removing device and method for a shuttle car in an excavation face, belonging to the field of coal mine dust prevention and control. The air flow diffuser is connected with the high-pressure air duct through a high-pressure rubber hose at the outlet section; the air flow diffuser is provided with a multi-layer air guide plate near the outlet, and the air guide plates are evenly distributed on the air guide plate, and the air guide openings between the air guide plates are staggered. , the high-pressure gas flows into the air diffuser, the high-pressure air flow in the air diffuser is depressurized through the first layer of air deflectors, and flows out from the first layer of air guides, and then passes through the second layer of air guides until the last layer of air guides , Under the action of the staggered air guides, an air curtain is formed at the driver's position to disperse the dust at the driver's place, and move along with the shuttle driver's position to dispel the dust.
Description
technical field [0001] The disclosure belongs to the field of coal mine dust prevention and control, and in particular relates to an air curtain dust-repelling device and method for a shuttle car in a tunneling face. Background technique [0002] From now to the future, coal is still not one of the main energy sources in my country. With the comprehensive and mechanized mining of coal mines, dust hazards have gradually become one of the important hazards in coal mine safety production. Mine dust will accelerate mechanical wear and reduce roadways. Visibility can also cause respiratory diseases of dust-exposed personnel. Shuttle car is a kind of trackless rubber-wheeled vehicle that realizes short-distance and fast transportation in coal mines. With the development of tunneling technology, shuttle car is more and more applied to the excavation face, and its main function is to transfer the coal of the continuous shearer. On the feeder crusher, the shuttle car driver is the ma...
