Silencing function mechanical blower for mine

Abstract

The invention discloses a mechanical blower with noise reduction function for mines, which comprises a blower body, and the air inlet of the air inlet and the air outlet of the air outlet are both provided with a noise reduction device, the noise reduction device includes a shell, the The left and right sides of the inner cavity of the housing are respectively separated by a first buffer chamber and a second buffer chamber by a plastic plate, and partitions are arranged intersecting between the first buffer chamber and the second buffer chamber, and the outer walls of the partitions The upper and lower sides of the inner wall of the shell are fixed with sound-absorbing wedges, and the bottom end of the blower body is fixed with a shock-absorbing base, and the shock-absorbing base includes a fixed mounting plate, and the left and right sides of the fixed mounting plate are opened. There are fixing holes, the upper surface of the fixed mounting plate is tightly bonded with a sound-absorbing sponge, the upper surface of the sound-absorbing sponge is uniformly fixed with a shock absorbing spring, and the top of the shock absorbing spring is fixedly connected to the lower surface of the buffer rubber pad . The blower has a simple structure and better noise reduction effect.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a mechanical blower with noise reduction function for mines. Background technique [0002] The blower is mainly composed of the following six parts: motor, air filter, blower body, air chamber, base, and drip nozzle. The blower operates eccentrically by the biased rotor in the cylinder, and makes the volume change between the vanes in the rotor slot suck, compress and spit out air. During operation, the pressure difference of the blower is used to automatically send the lubrication to the drip nozzle, and drip into the cylinder to reduce friction and noise, and at the same time keep the gas in the cylinder from flowing back. This type of blower is also called a dicing blower. Blowers are gradually being used in various fields, and the blowers generally used in mines will generate a lot of noise during use due to the particularity of their environment, especially after the reve...

Problems solved by technology

Blowers are gradually being used in various fields, and the blowers generally used in mines will generate a lot of noise during use due to the particularity of their environment, especially after the reverberation of mines, making the noise even louder and greatly It affects the normal work of the staff and prevents the staff from having a good working environment
