Description

Technical Field

[0001] The utility model relates to the technical field of slurry pump protection, in particular to a ceramic slurry pump rear guard plate structure. Background Art

[0002] The main material of the ceramic slurry pump is ceramic, which has extremely high hardness and wear resistance, allowing it to withstand a lot of wear and corrosion, thereby extending its service life. In addition, the ceramic slurry pump also has good corrosion resistance and will not be corroded by most chemicals, which makes it usually more efficient than traditional metal pumps when handling liquids containing abrasive particles. Due to the durability of the ceramic slurry pump and the lack of regular replacement of parts, its maintenance cost is usually lower than other types of pumps, further reducing the cost of use. For this reason, a ceramic slurry pump rear guard plate structure is proposed.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN205744477U, which discloses a single-shell ceramic slurry pump, belonging to the field of liquid pump technology. In this technical solution, a bracket body and a pump body are included, and the pump body includes a tail cover, a rear guard plate, a sleeve and an impeller. The pump shaft in the bracket body is connected to the impeller, and the sleeve and the rear guard plate are both provided with a ceramic lining, and the impeller is made of ceramic. By arranging a ceramic lining in the sleeve and the rear guard plate, the impeller is made of ceramic material, which can improve corrosion resistance, cavitation resistance, wear resistance and high temperature resistance. The utility model has the advantages of simple structure, reasonable design and light weight, and can be widely used in various working conditions with high wear, strong corrosion, severe cavitation and high temperature liquid transportation, such as mineral processing, coal washing, desulfurization and dust removal in power plants, petrochemical industry, tailings treatment, etc.

[0004] Based on the search of the above patents and combined with the equipment in the prior art, it was found that since the rear guard plate of the ceramic slurry pump is an integral ceramic structure, when the equipment is in a tightened state, the high external pressure will cause the ceramic sheath and guard plate to be crushed, and when the equipment is filled, the corrosive slurry and the metal body are not separated, resulting in insufficient sealing of the equipment filler. The existence of these problems affects the use of the device. Utility Model Content
