Problems solved by technology
Due to the uncontrollable amount of water and the uncontrollable concentration of the slurry in this method, and because the pulping material has a short contact time with water, there is still a large amount of unmelted soil in the filtered slurry, the pulping effect is not ideal and the utilization rate of the pulping materi

The invention relates to a grouting pool for coal mine fire extinguishing grouting, and belongs to the field of fire extinguishing devices for coal mines. The grouting pool for the coal mine fire extinguishing grouting comprises a main chamber, a stirrer, a filtering cavity and a motor, the main chamber is connected with the filtering cavity, a filter screen is arranged at the connecting positionof the main chamber and the filtering cavity, a water adding port is formed in the upper portion of the right side of the main chamber, and the lower portion of the right side of the main chamber communicates with a slurry storage pool. According to the grouting pool for the coal mine fire extinguishing grouting, the problems of pipe blockage and unstable slurry concentration can be greatly relieved, the fire extinguishing efficiency can be improved, and the fire extinguishing speed and quality can be ensured.
Description
Technical field [0001] The invention relates to a grouting tank for fire extinguishing grouting in coal mines, belonging to the field of fire extinguishing devices for coal mines. Background technique [0002] Grouting to prevent and extinguish fire is one of the common methods of coal mine fire prevention. The prepared slurry is injected into the fire area or designated area, and the fire is achieved by cooling and isolating oxygen. The slurry is prepared by uniformly mixing clay and other slurry materials with water. Mud, the residue in the mud is filtered 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 form a slurry into the slurry pipeline after being stirred by a mixer. This method cannot control the amount of water and the concentration of the slurry. Due to the short contact time bet...
