Description

Technical Field

[0001] The utility model relates to the technical field of grinding pumps, in particular to an anti-clogging and high-efficiency grinding pump. Background Art

[0002] Grinding pumps are commonly used in material processing. These devices utilize high shear and friction forces to grind solid particles while simultaneously dispersing and mixing liquids. Combining grinding, dispersion, and mixing, they are widely used in the chemical, pharmaceutical, food, plastics, and cosmetics industries. Grinding pumps operate by utilizing the high shear and friction forces between a high-speed rotating rotor and stator to grind materials. Liquid is drawn into the pump's inlet and dispersed between the particles, which are sheared and rubbed. This breaks the particles down into smaller pieces while simultaneously mixing them evenly with the liquid.

[0003] For example, the high-efficiency solid-liquid mixing and grinding pump disclosed in authorization publication number CN214439851U features a crushing shaft that moves at the top end of the solid feed inlet. Crushing plates are installed on the outer wall of the crushing shaft, and crushing blades are fixed to the outer wall of the crushing plates. The motor is mounted on one side of the solid feed inlet, which is also equipped with a liquid feed inlet. A reinforcement structure is provided within the solid feed inlet. This utility model not only improves the operating efficiency of the solid-liquid mixing and grinding pump, achieves a vibration-damping effect, and strengthens the rigidity of the solid feed inlet of the solid-liquid mixing and grinding pump.

[0004] However, the above method is mainly for pre-processing and crushing of single fixed materials, and does not crush the materials after solid-liquid mixture. For the objects after solid-liquid mixture, adhesion or even blockage may occur. At the same time, the crushing blade is not easy to replace. For this reason, we propose an anti-blocking and high-efficiency grinding pump. Utility Model Content
