Problems solved by technology

[0002] At present, asbestos is used as the sound-absorbing material for the sound-absorbing material of the axial-flow fan of the air-driven sprayer used in the domestic market. However, since the spray cylinder is only filled with asbestos, the sound is easily released after being absorbed, and the sound-absorbing area is thin. It is easy to cause the whistling sound generated by the fan to resonate with the wall of the cylinder, forming a lot of noise and causing environmental pollution

Abstract

The invention discloses a dust-removing air supply sprayer provided with a silencer, belonging to the technical field of an air supply sprayer. The environment-friendly dust-removing air supply sprayer provided with the silencer has the technical key points that the environment-friendly dust-removing air supply sprayer comprises an axial flow fan; an air outlet arranged in front of the axial flow fan is connected with a spray cylinder; a silencing ring is sheathed in the spray cylinder; the external diameter of the silencing ring is less than the internal diameter of the spray cylinder; a silencing area is formed between the spray cylinder and the silencing ring; and the silencing area is internally filled with sound absorption cotton. The invention aims at providing the dust-removing air supply sprayer provided with the silencer, which is compact in structure and good in use effect; and the environment-friendly dust-removing air supply sprayer is used for removing and inhibiting dust for the dust pollution caused by a large open coal mine and fugitive dust emission pollution caused by coal storage yard, transportation, crushing and the like.

Description

technical field [0001] The invention relates to a sprayer, more specifically, to an environment-friendly dust-removing air-supply sprayer with a sound-absorbing device. Background technique [0002] At present, asbestos is used as the sound-absorbing material for the sound-absorbing material of the axial-flow fan of the air-driven sprayer used in the domestic market. However, since the spray cylinder is only filled with asbestos, the sound is easily released after being absorbed, and the sound-absorbing area is thin. It is easy to cause the whistling sound generated by the fan to resonate with the wall of the cylinder, forming a lot of noise and causing environmental pollution. Contents of the invention [0003] The object of the present invention is to aim at the deficiencies of the above-mentioned prior art, and provide a kind of environment-friendly dust-removing air-supply sprayer with a sound-absorbing device which has a compact structure and good sound-absorbing effe...
