Description

Technical Field

[0001] The utility model relates to the technical field related to desalination equipment, in particular to a cathode product desalination device. Background Art

[0002] During the molten salt electrolysis process, the negative electrode product is often mixed with molten salt electrolyte. The traditional way to remove the molten salt electrolyte is generally to use vacuum distillation. The working principle of this process is to separate the molten salt from the material by heating and evaporating the molten salt in a vacuum environment and then condensing and collecting it. The process requires high temperature and vacuum, complex equipment, and high energy consumption.

[0003] The working principle of the rotating basket is to separate materials by melting molten salt in a high temperature environment through rotating motion. The materials are placed in the basket, and then the centrifugal force causes the liquid or smaller particles to pass through the mesh, while the larger solid particles are retained in the basket.

[0004] In the process of cathode product desalination, the cathode product molten salt is placed in a mesh basket for dry post-treatment, and then the mesh basket is rotated at high speed to separate the cathode product from the molten salt. However, most general rotating mesh baskets are only suspended by the top shaft, which causes the mesh basket containing the cathode product molten salt to shake due to the large centrifugal force in a high-speed environment, which is dangerous and may also result in incomplete desalination. Utility Model Content

[0005] Based on this, it is necessary to provide a cathode product desalination device that can prevent the basket from shaking in order to address the problem that the common rotating basket shakes during the desalination process.

[0010] In one embodiment, the upper shaft and the lower shaft are both coaxially arranged with the central axis of the basket body.

[0011] In one embodiment, the lower shaft is rotatably connected to the support member via a bearing.

[0012] In one of the embodiments, a baffle is fixed on the lower shaft, and the projection of the bearing along the vertical direction is located inside the baffle.

[0013] In one of the embodiments, a lateral baffle surrounding the bearing is also fixed to the lower end surface of the baffle, and the bearing is at least partially located in the lateral baffle.

[0014] In one of the embodiments, the outer ring of the bearing is fixed to the support member, and a plug connector is fixed to the bottom end of the lower shaft, and the plug connector can be plugged and fixed to the inner ring of the bearing.

[0015] In one embodiment, the reaction furnace includes a furnace body and a furnace cover detachably fixed to the furnace body, and the motor is fixed to the furnace cover.

[0016] In one embodiment, the bearing is made of silicon nitride ceramic.

[0017] In one of the embodiments, the material basket further comprises a basket cover detachably fixed to the top of the basket body, and the bottom end of the upper shaft is fixed to the basket cover.

[0018] In one embodiment, the bottom of the basket cover has an annular protrusion that can be inserted into the basket body, and the basket cover and the basket body are fixed by bolts that penetrate the basket body and the annular protrusion.
