Wind power expander type strong power air curtain dust controlling device

Abstract

The invention discloses a wind power expander type strong power air curtain dust controlling device. The wind power expander type strong power air curtain dust controlling device comprises a base and an air curtain generator arranged on the base. The air curtain generator comprises a first fixing plate, a second fixing plate and an air spraying mechanism clamped between the first fixing plate and the second fixing plate. The first fixing plate, the second fixing plate and the air spraying mechanism are fastened through a plurality of screws. The air spraying mechanism comprises a front disc and a rear disc, a gap is formed in a semicircular covering position of the front disc and the rear disc, the rear disc is internally provided with a circular air chamber and an air spraying chamber, the air wall of the air chamber is connected with the air chamber through a diverting port and an air groove, the first fixing plate and the front disc are provided with a round air inlet, and the air inlet is communicated with the air chamber. A small amount of underground pressure wind is adopted as power, a powerful air curtain is formed through the fluid mechanics principle, a protection layer is formed in front of an operator, dust invasion is prevented, power is not needed, and therefore potential safety hazards of electric appliances under a coal mine are avoided.

Description

technical field [0001] The invention relates to the field of dust control, in particular to a wind expander type powerful air curtain dust control device. Background technique [0002] In underground mines, a large amount of dust is generated during the cutting process of the fully-mechanized excavator, which fills the entire operation site. Since the driver of the fully-mechanized excavator is closest to the dust-producing point, the dust obstructs the staff's sight, which is likely to cause accidents and seriously endanger the health of the operators. . [0003] At present, water pipes are generally used for dust removal by sprinkling and spraying, which is mainly realized by internal and external spraying of fully-mechanized excavators.

Problems solved by technology

[0002] In underground mines, a large amount of dust is generated during the cutting process of the fully-mechanized excavator, which fills the entire operation site. Since the driver of the fully-mechanized excavator is closest to the dust-producing point, the dust obstructs the staff's sight, which is likely to cause accidents and seriously endanger the health of the operators.

[0003] At present, water pipes are generally used for dust removal by sprinkling and spraying, which is mainly achieved by spraying inside and outside the excavator. If the spray is too small, it will affect the dust removal effect, and if the spray is too large, it will affect the line of sight of the excavator.

Therefore, relying solely on the spray dust removal effect of fully mechanized excavators is not ideal.

At present, on the basis of water spray dust removal, a fan is added for dust removal, but this dust removal method still has the following disadvantages: because the air volume and speed of the dust removal fan cannot completely process the dust generated in time, the dust will spread, seriously affecting the health of drivers and affecting Fan dust removal effect

However, there are disadvantages of this device: first, the compressed air directly using the compressed air pipe consumes a lot of air, which is not energy-saving; second, it is very noisy; Turbulent flow, the air curtain is uneven and unstable, but the dust is blown away to form new diffuse pollution
