Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of mine safety exploitation auxiliary equipment, specifically is the fire extinguishing material fast supply device for gangue mountain spontaneous combustion prevention. BACKGROUND

[0002] In the process of mining, coal seam spontaneous combustion is one of the major safety hazards. The glue injection fire extinguishing technology is a widely used prevention and control method, which principle is that solid powder base material (such as loess, fly ash, etc.) is mixed with water and liquid coagulant in proportion to form a gel-like slurry, which is injected into high temperature or fire area through the pumping system to play the role of temperature reduction and oxygen isolation.

[0003] The existing fire extinguishing glue slurry needs to wait for a long time to make the slurry mixed uniformly after the quantitative raw materials are put in once during stirring, and then the slurry can be discharged and supplied. If the slurry is completely injected and consumed during fire extinguishing, the next batch of slurry needs to be stirred before the fire extinguishing can continue. The glue injection slurry cannot be continuously and quickly supplied.
