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

Embodiment

[0033] see Figure 1-7 , a low-noise and energy-saving double-shell slurry pump, including a bracket 1 and a pump body 2, the pump body 2 is fixedly connected with the bracket 1, the bracket 1 is connected with a stepped shaft 3 through a bearing frame mechanism, and the bearing frame The mechanism includes a support cylinder 31, which is fixedly connected with the bracket 1. The support cylinder 31 is connected with the stepped shaft 3 through a plurality of ball bearings 32, which is convenient to improve the rotation stability of the stepped shaft 3, and has better lubrication and longer service life. Long, the stepped shaft 3 is rotatably connected with the pump body 2, and the pump body 2 is connected with a liquid separation mechanism. The liquid separation mechanism includes a thick tube 26, which communicates with the pump body 2, and the thick tube 26 is fixedly connected with a separation filter plate 27. The separation filter plate 27 is connected to the pump body 2...

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...
