Description

A Mine Silencer Centrifugal Dust Collector Fan

technical field

The utility model relates to the field of mine engineering equipment, in particular to a mine-used sound-absorbing centrifugal dust-removing fan.

Background technique

At present, in the process of mining, a large amount of dust is generated due to processing and crushing, which may cause potential harm to the surrounding environment and human body. Therefore, it cannot be directly discharged into the atmosphere and must be treated by dust removal. The dust removal fans currently in use usually use spray dust removal, which has a single form, high noise and unsatisfactory dust removal effect, which is the deficiency of the prior art.

Utility model content

The technical problem to be solved by the utility model is to provide a mine-used sound-absorbing centrifugal dedusting fan, which is convenient for dedusting in coal mining.

The utility model adopts following technical scheme to realize the object of the invention:

A mine-used sound-absorbing centrifugal dust-removing fan, including a base, is characterized in that: a fixed block is fixed above the base, a motor is fixed above the fixed block, and the output shaft of the motor passes through the small hole on the back of the arc-shaped sound-absorbing shell Hinged with the impeller, the bottom end of the arc-shaped sound-absorbing shell is fixedly connected to one end of the square ventilation duct, and the other end of the square-shaped ventilation duct is fixedly connected to the square sound-absorbing shell, and the upper, middle, and lower parts of the square sound-absorbing shell are respectively fixed with The top plate is fixed with a group of nozzles, the bottom surface of the top plate is fixedly connected with three branch water pipes, the other end of the three branch water pipes is fixedly connected with the water supply tank through the water valve, and the square sound-absorbing shell is fixedly connected with the exhaust hood.

As a further limitation of the technical solution, the arc-shaped sound-absorbing shell and the square sound-absorbing shell adopt multi-layer sound-absorbing materials.

Compared with the prior art, the advantages and positive effects of this utility model are: the motor drives the impeller to rotate, the air in the arc-shaped sound-absorbing shell is moved outwards by the action of centrifugal force, and a vacuum is generated in the center of the impeller, so that the shaft from the air inlet To inhale the air, the inhaled air turns 90° at the impeller inlet, gets kinetic energy and pressure energy under the action of the impeller, and then throws it out from the arc-shaped sound-absorbing shell. housing, exhaust from the exhaust hood. Open the water valve at the same time, the water from the water supply tank passes through the three-branch water pipe, and is sprayed from the nozzle on the top plate along the upper, middle and lower directions, so that the water and the dust in the air are adsorbed and cohesive with each other, and the water falls through its own gravity to achieve The role of dust removal. The arc-shaped sound-absorbing shell and the square sound-absorbing shell adopt multi-layer sound-absorbing materials to achieve good sound-absorbing effect. The utility model has the advantages of novel structure, simple operation and low cost, and can achieve good effects of dust removal and noise reduction.

Detailed ways

A specific embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present invention is not limited by the specific embodiment.

As shown in Figures 1-7, the utility model includes a base 5, a fixed block 4 is fixed above the base 5, a motor 2 is fixed above the fixed block 4, and the output shaft of the motor 2 passes through an arc-shaped noise reduction The small hole on the back of the casing 1 is hinged to the impeller 3, the bottom end of the arc-shaped sound-absorbing casing 1 is fixedly connected to one end of the square ventilation duct 11, and the other end of the square ventilation pipe 11 is fixedly connected to the square sound-absorbing casing 7, and the square The upper, middle and lower parts of the sound-absorbing shell 7 are respectively fixed with a top plate 8, the top plate 8 is fixed with a group of nozzles 9, the bottom surface of the top plate 8 is fixedly connected with a three-branch water pipe 13, and the other end of the three-branch water pipe 13 passes through the water The valve 12 is fixedly connected to the water supply tank 6, and the square sound-absorbing shell 7 is fixedly connected to the exhaust hood 10.

The arc-shaped sound-absorbing shell 1 and the square sound-absorbing shell 7 are made of multi-layer sound-absorbing materials.

The working process of the utility model is as follows: the motor 2 drives the impeller 3 to rotate, the air in the arc-shaped sound-absorbing shell 1 moves outwards under the action of centrifugal force, and a vacuum is generated in the center of the impeller 3, so that the air is axially sucked in from the air inlet, and the air is sucked in. After turning 90° at the entrance of the impeller 3, the air obtained kinetic energy and pressure energy under the action of the impeller 3 is thrown out from the arc-shaped sound-absorbing shell 1, and enters the square sound-absorbing shell through the concentration and diversion of the square ventilation duct 11 7. Exhaust from the exhaust hood 10. Open the water valve 12 at the same time, the water passes through the three-branch water pipe 13 from the water supply tank 6, and is sprayed from the nozzle 9 of the top plate 8 along the upper, middle and lower directions, so that the water and the dust in the air are adsorbed, cohesive with each other, and pass through itself Due to the gravity, it falls to realize the function of dust removal. The arc-shaped sound-absorbing shell 1 and the square sound-absorbing shell 7 adopt multi-layer sound-absorbing materials to achieve good sound-absorbing effect. The utility model has the advantages of novel structure, simple operation and low cost, and can achieve good effects of dust removal and noise reduction.

What is disclosed above is only a specific embodiment of the utility model, but the utility model is not limited thereto, and any changes conceivable by those skilled in the art should fall within the protection scope of the utility model.
