Saizhi Huangni Fire Prevention and Extinguishing Grouting Station Integrated Mobile Pulping Station Pulping Capacity 0-120 cubic meters/h

Description :

　　The phenomenon of spontaneous combustion of coal powder in coal mines is one of the causes of coal mine fires. One solution is to inject grout into the goaf of the coal mine to isolate the coal powder from the air and solve the safety hazards of coal powder spontaneous combustion. The coal mine grouting fire prevention technology is to mix loess, fly ash, tailings, etc. with water in a certain proportion to make a uniform slurry, which is transported to the fire treatment area for grouting fire prevention. The high-speed slurry making machine for mining fire prevention and extinguishing grouting system equipment has uniform slurry making, low energy consumption, obvious slag discharge effect, and long service life.

　　High speed slurry machine configuration for mining fireproof grouting system equipment:

　　Including feeding hopper, feeding pipe, slag discharge device, pulping device, slag discharge port, slurry outlet, slurry filter screen, sealing ring, L-shaped fixing frame, Z-shaped fixing frame, spiral blade, agitator, and fixing frame; The feeding hopper is installed at the top of the feeding pipe; The bottom of the feeding pipe is connected to the pulping device and the slag discharge device; The slag discharge device comprises a screw conveyor, a filter cartridge, and a motor; One end of the filter cartridge is inserted into the feeding tube and fixedly connected to the feeding tube, and the other end is vertically connected to a slag discharge port; The spiral conveyor is installed inside the filter cylinder, and its outer end is connected to a slag discharge motor; The pulp making device is installed outside the slag discharge device, including a mixing drum located inside and a fixed frame located outside; The interior of the mixing drum is uniformly distributed with multiple sets of agitators along its length, each set of agitators including multiple arc-shaped blades uniformly distributed along the circumference of the mixing drum, and slurry outlets are provided between adjacent blades; The fixed frame is a set fixed to the outside of the mixing drum, with both ends sealed to the mixing drum, and a gap left between its inner wall and the outer wall of the mixing drum; The two ends of the mixing drum are respectively connected to the slag discharge device through bearings for rotation; The mixing drum is equipped with gears, which are driven by a motor to drive the pulp making device to rotate; The pulp making device is equipped with a pulp outlet at one end away from the feeding pipe.

　　Working principle of high-speed pulping machine:

　　The raw materials and water enter the feeding pipe through the feeding hopper, and the slag discharge device starts to operate. The initial slurry mixed with water is sent to the slag discharge port. During the transportation process, the particle size conforms to the principle of pulp making and is discharged into the pulp making device through the filter screen of the slurry filtration cylinder. The remaining waste raw materials will be discharged from the slag discharge port. After the raw materials are screened and enter the pulp making device, they are continuously stirred by the inner mixing drum and mixer. After the mixing is completed, the valve is opened, and the slurry flows into the outer fixed frame of the pulp making device through the slurry outlet, and is discharged from the slurry outlet. During the flow of the slurry, the double-layer structure has a secondary filtering effect. The pulp making device is driven by a motor to rotate the gears, and the slag discharge device is driven by a slag discharge motor to operate the screw conveyor.

　　Characteristics of high-speed slurry machine for mining fireproof grouting system equipment:

　　Its slag discharge and pulp making use of independent structures, the screw conveyor is horizontal, and the pulp making device adopts a double-layer structure with gaps between the two layers. It also plays a supporting and secondary filtering role and uses a stirrer to accelerate the production of pulp. Impurities in the pulp making process can be filtered without a filter screen inside, which has the advantages of uniform pulp making, low energy consumption, obvious slag discharge effect, small longitudinal space, and long service life.

　　The new high-speed pulping machine reduces the overall height, which is conducive to loading pulping raw materials and improves the height requirements for the loader and pulping plant. The pulp making device adopts a double-layer structure, with the outer layer fixed and suspended for fixing purposes, while leaving a certain gap with the inner layer, playing a role in secondary filtration and pulp discharge. The inner layer of the pulp making device is arranged along the circumference with the blades of the agitator, and there are slurry outlet holes between the blades to allow the slurry to flow out smoothly. The pulp making device relies on gear transmission. The slag discharge device adopts a horizontal structure, which is independent of the pulp preparation device. The pulp raw materials enter the slag discharge device directly from the feeding port and are separated from the slurry and residue under the mixing of water. The residue is directly discharged from the slag discharge port, and the slurry will enter the pulp preparation device for further mixing and stirring by the mixer. The pulping machine adopts a sealing ring form, and both the L-shaped and Z-shaped fixed frames are equipped with sealing devices to prevent the slurry from entering the transmission system. The feed inlet of the pulp mill is connected to the slag discharge device by a circular arc and is tangent at the corner, solving the problem of blockage caused by sudden changes in the transmission channel.
