Abstract

Technical Field
[0001] The utility model relates to the technical field of slurry pumps, and more specifically to a slurry pump for mineral processing. Background Art
[0002] A slurry pump is a machine that increases the energy of a solid-liquid mixed medium by means of centrifugal force, and converts electrical energy into kinetic energy and potential energy of the medium. Under the action of centrifugal force, the liquid is thrown from the center of the impeller to the outer edge and gains energy, leaving the outer edge of the impeller at high speed and entering the volute pump casing. In the volute pump casing, the liquid slows down due to the gradual expansion of the flow channel, and part of the kinetic energy is converted into static pressure energy, and finally flows into the discharge pipe at a higher pressure and is delivered to the required place. It is mainly suitable for: mining, power plants, dredging, metallurgy, chemical industry, building materials and petroleum industries.
[0003] However, when conveying solid-liquid mixed media, some condensed ore materials are easy to clog the pump body, affecting the medium conveying, and solid ore entering the pump body is easy to damage the impeller. For this reason, we proposed a slurry pump for mineral processing. Utility Model Content
