Technical Field

[0001] The utility model relates to the technical field of crushing and dispersing devices, in particular to a cement material crushing and dispersing device for conveying with a screw pump. Background Art

[0002] The screw pump is a low-pressure, dilute phase conveying equipment. In some cases, a screw pump is used when conveying cement materials. When using a screw pump to convey cement materials, it is necessary to first use a crushing and breaking device to crush the cement materials to facilitate the cement materials to enter the interior of the screw pump and improve the conveying efficiency and effect of the screw pump.

[0003] When using a crushing and dispersing device to disperse cement materials, a conveying mechanism is usually placed under the equipment to convey the crushed cement materials to the feed inlet of the spiral pump. Since the use environments of the spiral pump and the dispersing device are different and the leg length of the dispersing device is fixed, the height of the dispersing device cannot be adjusted according to actual needs during use so as to better place conveying mechanisms of different specifications under the dispersing device, resulting in certain limitations in the use of the crushing and dispersing device. Utility Model Content
