Abstract

A continuous grout making machine used for fire preventing and extinguishing in a coal mine is provided with a grout cylinder, a rolling cylinder and a drive device of the rolling cylinder, wherein the rolling cylinder and the drive device are contained in the grout cylinder. The grout cylinder and the rolling cylinder are obliquely installed, a material inlet is formed in the higher end of the rolling cylinder, a slag outlet is arranged in the other end of the rolling cylinder, the end, close to the material inlet, of the rolling cylinder is provided with a material inlet flow guide mechanism and a material inlet buffering mechanism, the end, close to the slag outlet, of the rolling cylinder is provided with a slag outlet flow guide mechanism and a slag outlet buffering mechanism, a grout outlet is formed in the end, close to the slag outlet, of the grout cylinder, a filter net is arranged on the outer circumference of the rolling cylinder, the inner wall of the rolling cylinder is fixedly provided with axial stirring pieces, grout raw materials are stirred by the stirring pieces to form grout, the grout penetrates through the filter net, enters the grout cylinder and is discharged from the grout outlet, and slag is discharged out of the slag outlet through the slag outlet flow guide mechanism and the slag outlet buffering mechanism of the rolling cylinder.

Description

Technical field [0001] The invention relates to the technical field of fire prevention and fire prevention for coal mine spontaneous combustion, in particular to a continuous pulping machine for coal mine fire prevention and fire prevention. Background technique [0002] Grouting to prevent fire extinguishing is one of the commonly used methods for coal mine fire prevention. The prepared slurry is injected into the fire area or designated area, and the fire is extinguished by cooling and isolating oxygen. Slurry is prepared by uniformly mixing slurry materials such as clay and water to form a slurry, and filter out the residue in the slurry through a filter to form a slurry. At present, the pulping method of the ground pulping station is to use a high-pressure water gun to flush the mud from the mound, flow into the mud ditch, remove the debris, enter the mud mixing tank, and then inject it into the slurry pipeline after being stirred by a mixer. This method cannot control the a...
