Description

Technical Field

[0001] The utility model belongs to the technical field of coal mine engineering, and particularly relates to a circulating cooling device for a coal mine air compressor. Background Art

[0002] A coal mine refers to a mining area rich in coal, generally divided into underground coal mines and surface coal mines. During the mining process of underground coal mines, in order to prevent harmful gases such as carbon dioxide in the mine from exceeding the standard and affecting the health of workers, an air compressor is usually installed in the mine to convey fresh air into the mine. However, in order to prevent the air compressor from being damaged due to long-term operation, a cooling device is generally installed on the air compressor to cool the motor of the air compressor;

[0003] A document with the publication number of CN215949949U discloses a stable circulating cooling device for an air compressor, including an air compressor. A side fixed substrate is fixedly installed on the left side surface of the air compressor. An outer support structure is movably connected inside the side fixed substrate. An outer motor is installed through the outer support structure. A fan blade is fixedly installed on the output shaft of the outer motor. An outer layer plate is fixedly installed inside the outer support structure;

[0004] However, it still has the following drawbacks in actual use:

[0005] 1. In the above-mentioned circulating cooling device for the air compressor, the outer support structure is movably connected inside the side fixed substrate, the outer motor is installed through the outer support structure, and the fan blade is fixedly installed on the output shaft of the outer motor. The fan blade is driven by the outer motor to cool the motor of the air compressor. However, during the use process, since the fan blade is located above the motor of the air compressor, the fan blade dissipates heat unevenly to each part of the motor of the air compressor, which may cause local overheating of the motor of the air compressor;

[0006] 2. In the above-mentioned circulating cooling device for the air compressor, the outer support structure is movably connected inside the side fixed substrate, the outer motor is installed through the outer support structure, and the fan blade is fixedly installed on the output shaft of the outer motor. The fan blade is driven by the outer motor to cool the motor of the air compressor. However, during the use process, since the air in the mine contains a large amount of solid particles and the air humidity in the mine is relatively high, and the above-mentioned cooling device directly uses the air containing a large amount of solid particles and high humidity to cool the motor of the air compressor, which may affect the service life of the motor of the air compressor due to the solid particles or moisture in the air.

[0007] Therefore, we provide a circulating cooling device for a coal mine air compressor to solve the above problems. Content of the Utility Model

At the same time, the moisture in the coal mine air is absorbed by the water-absorbing filler in the filter cylinder, and solid particles are filtered by the filter plate, solving the problem that the existing device is not convenient for avoiding the large air humidity and dust content in the coal mine from affecting the operation of the motor of the air compressor.
