A semi-closed automatic dust reduction device and automatic dust reduction method for belt reload point

Abstract

The invention relates to a semi-enclosed automatic dust-reducing device for a belt transfer point, comprising a semi-enclosed dust cover, an upper belt is arranged in the middle of the semi-enclosed dust cover, a lower lap belt is provided at the lower part, and the semi-enclosed dust cover The opening is provided with a foam film sealing device; the foam film sealing device communicates with the foam injection pump through the foam material injection pipe in the semi-closed dust cover; inside the semi-closed dust cover is provided with a plurality of air-water Spray device, gas concentration monitoring sensor, dust concentration monitoring sensor; the gas concentration monitoring sensor and dust concentration monitoring sensor are electrically connected to the input end of the controller, and the controller is electrically connected to the foam film forming sealing device and the air-water spraying device; use a semi-closed The device can effectively blow and dilute the gas concentration in the confined space, discharge the harmful gas through the top outlet, prevent the accumulation of gas in the confined space, and effectively treat the dust at the same time.

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] Restricted by the production conditions in underground coal mines, a large amount of dust will be generated during many operations such as mining, excavation, belt coal transportation, transshipment, and support removal. Coal mine dust is mainly rock dust and coal dust, which is extremely harmful. It not only pollutes the workplace, endangers human health, causes pneumoconiosis and skin diseases, but also accelerates machine wear, shortens the use time of precision instruments, and reduces the visibility of the workplace. , Increase work-related 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 ensu...

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.
