An underground multi-stage wind power material conveying device and material conveying method

Abstract

The invention discloses an underground multi-stage wind power material conveying device and a material conveying method. The material conveying device includes a high-pressure air generation and storage device, a high-pressure air pipeline, a material reloading device, an N-level feeding device and a wind conveying pipeline, and the feeding device includes a material inlet and a material inlet, where N is a positive integer And N≥2; the high-pressure air pipeline is connected with the high-pressure air generation and storage device and the wind conveying pipeline, the material inlet of the first-stage feeding device inputs the material conveyed by the material transfer device, and the feed material of the latter-stage feeding device The mouth is connected with the feeding port of the previous stage feeding device through the wind conveying pipeline, and the feeding port of the Nth stage feeding device conveys the material to the filling working face through the wind conveying pipeline; the technical scheme of the embodiment of the present invention realizes Long-distance wind conveying of materials in coal mines.

Description

Technical field [0001] The embodiment of the present invention relates to the technical field of material transportation, in particular to an underground multi-stage wind power material transportation device and a material transportation method. Background technique [0002] China's coal production accounts for nearly one-half of the world's total output. With coal production, a large amount of coal gangue and other materials will be produced. The realization of coal gangue and other materials in underground transportation and in-situ filling mining is the future development trend of coal mining. [0003] The transportation of coal gangue and other materials and the in-situ filling mining process need to transport the sorted coal gangue and other materials to the goaf for filling. The existing conveying devices for coal gangue and other materials mainly use belt conveyors, scrapers, Mainly hydraulic pipelines. In the narrow space underground in coal mines, belt conveyors and scrap...

AI Technical Summary

Problems solved by technology

In the narrow space of underground coal mines, belt conveyors and scraper conveyors need to occupy a large space, which is not conducive to equipment layout and use, and also limits the long-distance transportation of materials such as coal gangue
