The application discloses a shotcrete rebound-reducing agent and a preparation method thereof. The shotcrete rebound-reducing agent is prepared from the following raw materials in mass percentage: 15-30% of a quick-setting component, 2-5% of a viscosity-increasing component, 10-15% of a reinforcing component, 2-5% of an anti-freezing component, 1-4% of a stabilizer, and the rest of water; and the viscosity-increasing component is a combination of polyvinylpyrrolidone and modified carboxymethyl cellulose. The prepared shotcrete rebound-reducing agent has the advantages of good sprayability, high hourly strength, good anti-freezing and stability, and the like, can improve the working performance of shotcrete, reduce the content of a quick-setting agent and significantly reduce the rebound rate of shotcrete, and has good economic benefits.

The utility model discloses a long -acting anti -block filter device relates to agricultural irrigation technical field, including the water tank, the water tank one side is connected with the water inlet pipe, the water tank opposite side is connected with the water delivery pipe, the inside of water tank is provided with the stirring broken subassembly, the water delivery pipe one end is connected with the connecting pipe, the inside of connecting pipe is provided with the filter drum, the utility model discloses beneficial effect is: the filter drum adopts 304 stainless steel and constitutes, and this material is firm and durable, corrosion -resistant, can adapt to various complex water quality environment, can prolong the service life of filter drum, at the same time, the filter drum inner wall is connected with the plug tube and the sleeve pipe cooperation, the sleeve pipe inner wall fixed three sets of sealing rings, not only guarantee the leakproofness of connection, prevent water leakage, still can block the impurity and enter the connecting pipe inside to a certain extent, reduce the accumulation of impurities at the connecting pipe, reduced the risk of blockage.

This invention provides a high-lift, long-distance filling pump device, belonging to the technical field of mining filling systems. It addresses the problem in existing mining filling operations where filling slurries such as tailings and waste rock slurries, due to their gravity and high concentration, easily form a sedimentation stratification phenomenon within the hopper, resulting in a thinner top and thicker bottom. The device includes a mounting plate, a second stirring paddle, a fixed guide box, an anti-sedimentation component, and an opening and cleaning component. The top of the second stirring paddle is rotatably connected to the inside of the fixed plate, and the bottom of the second stirring paddle is rotatably connected to the bottom of the hopper. The fixed guide box is fixedly connected to the front of the hopper. The anti-sedimentation component is located inside the hopper. The opening and cleaning component is located on the left side of the hopper. This invention disrupts the sedimentation stratification of the slurry, promotes the convergence of materials from the edges to the center, achieves stable pumping concentration and improves the uniformity of the filling body strength. The sliding door makes it easier to clean materials adhering to the internal structure of the hopper.
