Anti-blocking slurry pump

Abstract

The invention relates to the field of liquid variable-capacity machinery, in particular to an anti-blocking slurry pump which comprises a supporting assembly, a material pumping assembly and an anti-blocking assembly, the material pumping assembly comprises a first motor, a coupler, an impeller and a supporting rod, the supporting rod can drive the impeller to rotate when rotating, and the first motor rotates to drive the supporting rod and the impeller to rotate through the coupler; the anti-blocking assembly comprises a filter cover, a connecting rod, a brush rod and an outer sweeper, large-size particles can be isolated on the outer side of the filter cover through the filter cover and are prevented from entering the shell to cause blockage, and the supporting rod drives the connecting rod and the brush rod to move, so that the inner side of the filter cover can be cleaned through continuous rotation, and blockage is avoided; and the outer sweeper is rotationally arranged on the outer side of the filtering cover, impurities on the outer side of the filtering cover are cleaned, blocking is further prevented, and therefore impurities in slurry can be continuously filtered in the working process of the slurry pump, and the slurry pump is prevented from being blocked.

Description

technical field [0001] The invention relates to the field of liquid displacement machinery, in particular to an anti-clogging mud pump. Background technique [0002] In the process of oil field drilling, mud pumps are needed to pump out the mud in the oil well. The pumped mud contains various large particles of debris, which can easily block the mud pump, affect the normal operation of drilling work, and reduce work efficiency. Contents of the invention [0003] The object of the present invention is to provide an anti-clogging mud pump, which aims at isolating large particles of impurities outside the mud pump so that the mud pump can work for a long time and prevent the mud pump from being blocked. [0004] To achieve the above object, the present invention provides an anti-clogging mud pump, which includes a support assembly, a pumping material assembly and an anti-blocking assembly, the support assembly includes a base and a casing, the casing is arranged on the base, ...
