Embodiment Construction
[0019] The specific embodiment of the present invention will be further described in conjunction with the accompanying drawings.
[0020] Such as figure 1 As shown, a drum-type pulping machine includes a drum 4 with concentric cones at both ends and a cylinder in the middle. The two ends of the drum are the inlet 1 and the outlet 2, and the inner wall of the cone at one end of the outlet 2 There are rotating blades 3 on the top, the opening angle α of the inner wall at one end of the feed port 1 is greater than the opening angle β of the inner wall at the end of the discharge port, the diameter of the discharge port 2 is larger than the diameter of the feed port 1, and the roller 4 is supported on the frame mounted on the frame 8. On the roller 6, the frame 8 is also fixed with a driving device 5 that drives the drum to rotate through the ring gear 7 outside the drum, and the drum can rotate forward and reverse under the drive of the driving device.

The invention belongs to the technical field of fire control in mines, and discloses a drum-type grout-making machine, which solves the problems of incapacity of effectively separating impurities from grout, low grout concentration, grout-making discontinuity and high labor intensity in conventional grout-making methods. The two ends of the drum-type grout-making machine are provided with a concentric conical body respectively, while a middle part is provided with a cylindrical rolling drum; a feed port and a discharge hole are reserved at the two ends of the rolling drum respectively; rotating blades are arranged on the inner wall of the conical body at one end of the discharge hole; a divergence angle alpha of the inner wall at one end of the feed port is greater than the divergence angle beta of the inner wall at the discharge hole end; the diameter of the discharge hole is greater than that of the feed port; the rolling drum is supported on carrier rollers arranged on a stander; the stander is also fixed with a drive device which drives the rolling drum to rotate through a gear ring outside the rolling drum; and the rolling drum can positively and negatively rotate under the drive of the drive device. The drum-type grout-making machine has the characteristics of capacity of effectively separating the impurities, such as grass roots, stones and the like, from the grout, high grout concentration, high flow, operation continuity, great labor intensity reduction, long service life, simple structure, small occupation, simple operation and maintenance and low running cost.
Description
technical field [0001] The invention belongs to the technical field of fire prevention and extinguishing in coal mines, and relates to a pulping machine used for fire prevention and extinguishing in coal mines, in particular to a drum type pulping machine. Background technique [0002] Coal mine spontaneous combustion fire is one of the main disasters in the current coal mine production process. Preventive grouting is an effective method widely used in my country to prevent coal spontaneous combustion. Whether the mud can be prepared uniformly and quickly according to the designed concentration is the key factor to determine the grouting effect, and the mud should not contain impurities such as grass roots and stones, so as not to block the grouting pipeline. The pulping machine is the core equipment for mud preparation. At present, two pulping methods are mainly used: hydraulic flushing pulping and stirring tank mechanical stirring pulping. [0003] Hydroscouring pulping ...
