Technical Field
[0001] This utility model relates to the technical field of coal mine fire prevention and extinguishing equipment, specifically a continuous pulping machine for coal mine fire prevention and extinguishing. Background Technology
[0002] Coal mine fire extinguishing slurry is a special material specifically designed to extinguish coal mine fires or suppress the spread of fire. It is usually composed of a mixture of multiple components and has good flame retardant, cooling, covering, and adhesion properties. During the production process, the materials need to be stirred and mixed by a slurry mixer to give the slurry certain basic properties to meet the requirements for coal mine fire extinguishing.
[0003] This utility model relates to the field of coal mine fire prevention and extinguishing technology, and discloses a continuous pulping machine (CN221207549U) for coal mine fire prevention and extinguishing. It includes a housing, with a feed pipe fixedly connected to the top of the housing. A connecting shaft is rotatably connected inside the housing. A stirring rod is fixedly connected to the left side of the connecting shaft, and a sleeve is rotatably connected to the right side of the connecting shaft. A second stirring rod is fixedly connected to the outside of the sleeve. A bevel gear is fixedly connected to the right end of the sleeve, and a mounting plate is fixedly connected to the right end of the housing. In this utility model, the combined use of the motor, bevel gear, and other structures enables bidirectional stirring of the raw materials, resulting in more uniform mixing. This allows for continuous stirring of the raw materials, eliminating the need for multi-stage stirring and reducing the space occupancy of the pulping machine, thereby improving stirring efficiency. However, due to the adhesive properties of the slurry, auxiliary equipment is needed to guide the slurry during material transportation to ensure effective transportation. This transportation method undoubtedly reduces the utilization rate of equipment space, thereby reducing the space required for pulping, which in turn reduces production efficiency and causes problems for users.
[0004] Therefore, we propose a continuous pulping machine for fire prevention and extinguishing in coal mines. Utility Model Content

[0028] Working principle: For this type of continuous slurry mixing machine for coal mine fire prevention and extinguishing, the gelling material, flame retardant, thickener, and dispersant are first poured into the mixing chamber 1 through the opening at the top of the top cover 11 according to the required proportions of the coal mine fire extinguishing slurry. At this time, the user starts the servo motor 3, which drives the stirring blades 33 and the auger 34 to rotate synchronously through the transmission shaft 31. The stirring blades 33 and the auger 34 mix and stir the water-based slurry. When the water-based slurry is mixed and needs to be opened, the telescopic cylinder 47 is opened. The telescopic cylinder 47 pushes out, causing the storage baffle 4 to move along one side. At the same time, the upper part of the storage baffle 4 is supported by the top cover 11. The lower connecting arm 42 moves along the upper connecting arm 43, and the storage baffle 4 moves synchronously with the lower connecting arm 42. The telescopic cylinder 47 also rotates synchronously through the movable connecting head 471. Under the guidance of gravity and the push of the auger 34, the slurry flows out from the opening of the mixing chamber 1. At the same time, the slurry is received and guided by the slurry guide baffle 49 and falls into the collection device. Then, when the telescopic cylinder 47 retracts, the lower connecting arm 42 rotates back along the upper connecting arm 43, and the bottom of its storage baffle 4 contacts the bottom of the mixing chamber 1 until the bottom of the storage baffle 4 is completely attached to the mixing chamber 1. The opening of the mixing chamber 1 is then closed. The above operation is repeated to carry out the pulping operation.
