A molten salt submerged pump

Abstract

The invention discloses a fused salt submerged pump. The fused salt submerged pump comprises a motor and a rotating shaft connected with the motor. An impeller is arranged at the bottom of the rotating shaft. The fused salt submerged pump further comprises a sandwich-type tubular shell used for containing the rotating shaft and the impeller. The tubular shell and the rotating shaft are coaxially arranged. An inner layer and a sandwich layer of the tubular shell communicate with each other at the bottom end of the tubular shell. The bottom of the tubular shell is provided with an opening communicating with the external environment. An enclosure of the tubular shell communicates with a water outlet. The inner layer of the tubular shell serves as a water inlet pipe, water at the bottom of the tubular shell can enter the sandwich layer, and the water in the sandwich layer can be discharged out of the water outlet after being accumulated to a certain height. On the basis that the set lift is not influenced, the single-pipe-type design replaces a double-pipe-type design, the pipeline radial area is greatly decreased, and accordingly space occupation of the fused salt submerged pump is reduced; and meanwhile the working efficiency is improved. Moreover, due to the single-pipe-type symmetric design, radial force stressed in the working process is eliminated, and the service life of the fused salt submerged pump is greatly prolonged.

Description

technical field [0001] The invention relates to the technical field of material conveying, and more specifically relates to a molten salt submerged pump. Background technique [0002] High-temperature molten salt can be used for metal preparation and other purposes, and high-temperature molten salt itself needs to be transported by molten salt pump. [0003] At present, the commonly used molten salt submerged pump includes a motor, a rotating shaft and a cylindrical shell. The cylindrical shell is used as the outlet pipe of the molten salt submerged pump. It is also necessary to connect another outlet pipe on the side of the outlet pipe through the bottom of the pump. Water enters the inlet and water exits from two outlet pipes to realize the circulation process of related liquids. The independent outlet pipe often needs to be provided with multiple curved sections to facilitate the flow of the liquid to a suitable direction and position. With the above structural design, ...
