Mixing stirring system used for cold salt tanks

Abstract

The invention discloses a mixing stirring system used for cold salt tanks. The mixing stirring system used for cold salt tanks comprises a motor, a main driving rod, a first driving wheel, a second driving wheel, a first driven wheel, a second driven wheel, a first driving belt, a second driving belt, a main stirring paddle, a first auxiliary driving rod, a second auxiliary driving rod, and an auxiliary stirring paddle. The mixing stirring system is invented based on improvement of a conventional stirrer; the single motor is used for driving the stirring paddles arranged at different parts ina tank body to stir; the connecting mode of the stirring paddles with the driving rods is capable of providing molten salt in the tank body with a plurality of stirring modes; the three grade gear design of the first driving wheel and the second driving wheel is adopted, so that the motor is capable of realizing stirring at different rotating speed; upward inclined stirring paddles and downward inclined stirring paddles are adopted, so that full convective mixing of molten salt at the upper layer and the lower layer is realized, full uniform mixing of the molten salt at the upper layer and thelower layer in the tank body is realized, molten salt temperature is ensured to be uniform, and it is beneficial for working stability of power generation devices.

Description

technical field [0001] The invention belongs to the field of mechanical devices, in particular to a mixing and stirring system for cold salt tanks. Background technique [0002] Molten salt energy storage technology can solve the problem of energy storage in solar thermal power generation. The technology of using molten salt energy storage directly uses electricity to heat the molten salt and store it. When needed, the molten salt releases heat, and the steam turbine converts it into Electric energy, or through the heat exchange device to release the heat stored in molten salt for heating, this makes it possible to use surplus electric energy for grid-level energy storage. The scalable energy storage technology that uses electric energy to directly heat molten salt is in the power storage market. Wide application will also help reduce the cost of solar thermal power station projects. As the key equipment in the molten salt energy storage technology, the molten salt tank's p...

AI Technical Summary

Problems solved by technology

At present, the problem with ordinary molten salt tanks, especially those with larger capacity, is that the temperature of the molten salt in the molten salt tank cannot be guaranteed to be balanced and consistent, and the inconsistency of the molten salt temperature will affect the stability of the power generation system.
