Belt transferring point semi-closed automatic dust removing device and method

Abstract

The invention relates to a belt transferring point semi-closed automatic dust removing device which comprises a semi-closed dustproof cover. An upper belt is arranged in the middle of the semi-closeddustproof cover, and a lower lap joint belt is arranged on the lower portion of the semi-closed dustproof cover. A foam film forming sealing device is arranged on an opening of the semi-closed dustproof cover. The foam film forming sealing device communicates with a foam injection pump through a foam material injection pipeline arranged in the semi-closed dustproof cover. Multiple air-water spraying devices, a gas concentration monitoring sensor and a dust concentration monitoring sensor are arranged in the semi-closed dustproof cover. The gas concentration monitoring sensor and the dust concentration monitoring sensor are electrically connected with the input end of a controller. The controller is electrically connected with the foam film forming sealing device and the gas-water sprayingdevice. The semi-closed device is used, the gas concentration in limited space can be effectively blown away and diluted, the gas harmful gas is exhausted through a top outlet, the gas is prevented from being accumulated in closed space, and meanwhile dust can be effectively treated.

Description

Technical field [0001] The invention relates to the technical field of dust treatment, in particular to a semi-closed automatic dust reduction device and an automatic dust reduction method for a belt transfer point. Background technique [0002] Due to the restriction of production conditions, underground coal mines will generate a large amount of dust during many operations such as mining, tunneling, belt transportation, transfer, and support movement. The dust in coal mines is mainly rock dust and coal dust, which is extremely harmful. It not only pollutes the workplace, harms human health, causes pneumoconiosis and skin diseases, but also accelerates machine wear, shortens the use time of precision instruments, and reduces visibility in the workplace , Increasing work injuries, in addition, dust may explode under certain conditions, causing safety accidents. Therefore, the prevention and control of underground dust is one of the important contents to ensure the safe productio...

AI Technical Summary

Problems solved by technology

The use of closed measures can easily lead to excessive dust concentration in the confined space. For high-gas mines, after the gas decomposed in the coal body escapes in the confined space of the transfer point, it is easy to cause the problem of gas accumulation in the upper space, which seriously affects the safe production of coal mines.
