Low-noise and energy-saving double-shell slurry pump

Abstract

The invention relates to the technical field of slurry pumps, in particular to a low-noise and energy-saving double-shell slurry pump. The double-shell slurry pump comprises a bracket and a pump body,wherein the pump body is connected with the bracket, the bracket is connected with a stepped shaft, the stepped shaft is connected with the pump body, the pump body is communicated with a liquid distribution mechanism, the pump body is connected with a liquid discharging door through a rotating rod, the rotating rod is connected with a driving sleeve, the driving sleeve is connected with the bracket through a moving frame mechanism, a plurality of centrifugal rods are connected to the stepped shaft, the stepped shaft is sleeved with a transmission ring, flexible springs are connected betweenthe plurality of centrifugal rods and mounting grooves correspondingly, the plurality of centrifugal rods are all connected with the transmission ring, a circular ring is connected to the stepped shaft, the circular ring is connected with the moving frame mechanism, the pump body communicates with a telescopic liquid inlet pipe through an end cover, a synchronizing mechanism is installed between the pump body and the end cover, the stepped shaft is connected with a small impeller through a large impeller, and an elastic spring is connected between the large impeller and the small impeller. Thedouble-shell slurry pump is stable in starting, clean in use, long in service life, capable of easily adjusting displacement and good in use flexibility.

Description

technical field [0001] The invention relates to the technical field of slurry pumps, in particular to a double-shell slurry pump with low noise and energy saving. Background technique [0002] As we all know, the low-noise and energy-saving double-shell slurry pump is an auxiliary device used in the transportation of solid-liquid mixed liquid to lift and transport solid and liquid at the same time, so that the mixed liquid can move better. It has been widely used in mines, power plants, dredging, metallurgy and many other fields. [0003] The existing low-noise and energy-saving double-shell slurry pump includes a pump body and a bracket. The pump body and the bracket are fixedly connected. Protective plate, a sheath is installed between the pump cover and the pump body, the pump body is connected to the rotating shaft through the bearing, the impeller is connected to the rotating shaft, the pump cover is provided with a liquid inlet flange, and the liquid inlet flange is c...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned existing technical solutions still have the following defects. After use, the mixed liquid is more likely to remain in the cavity formed by the pump body and the pump cover. Long life, relatively easy to damage, and its displacement is relatively fixed, the flexibility of use is low, and after the mixed liquid is transported, further solid-liquid separation is required, the use limitation is high, and the practicability is poor
