Description

Technical Field

[0001] The utility model belongs to the technical field of slurry pumps, and in particular relates to a steel rope type stirring paddle with an anti-fracture structure. Background Art

[0002] A slurry pump is a machine that increases the energy of a solid-liquid mixed medium by the rotation of the impeller of a centrifugal pump. It is a device that converts electrical energy into kinetic energy and potential energy of the medium. The impeller is a semi-open impeller with stirring blades at the extension of the impeller suction side. It is mainly used in environmental protection, municipal engineering, thermal power plants, gas coking plants, refineries, steel mills, mining, papermaking, cement plants, food plants, printing and dyeing industries to pump concentrated liquids, thick oils, oil residues, turbid liquids, mud, mortar, quicksand, flowing sludge in urban sewage ditches, as well as fluids containing mud and slag and corrosive liquids.

[0003] The agitator paddles on the market are in use. Since the mud will cause great resistance to the agitator paddles during the pumping process, most of the existing agitator paddles use rigid shafts, which are not flexible and fracture-resistant. When they are subjected to excessive resistance, the shafts are prone to breakage, causing the agitator paddles to fail, thus affecting the use of the slurry pump. Therefore, how to prevent the agitator paddles from breaking and failing during use is a technical problem to be solved. Utility Model Content
