Description

Technical Field

[0001] This utility model relates to the field of material conveying technology, specifically to a semi-dry material conveying pump. Background Technology

[0002] Semi-dry materials typically refer to substances that contain a certain amount of moisture but are not completely liquefied, exhibiting high viscosity and a certain amount of solid particles. They do not pulverize like dry materials, nor are they as fluid as liquids. Common semi-dry materials include mud, slurry, solid particles in wastewater, slurries used in certain food processing, and intermediate materials in solid waste treatment.

[0003] Semi-dry material conveying pumps are used to convey materials with low moisture content or high viscosity. Due to the physical characteristics of semi-dry materials, the equipment used for conveying them needs to have a strong conveying capacity.

[0004] Currently, the main types of equipment for conveying semi-dry materials include screw pumps, piston pumps, plunger pumps, and gear pumps. However,

[0005] Semi-dry materials tend to adhere to the inner walls and internal components of conventional semi-dry material conveying equipment, thereby reducing conveying efficiency. Utility Model Content
