Grinding liquid mixing and supplying system

A grinding liquid mixing and supplying system, comprising:

• a stock solution barrel outputting a stock solution from a stock solution pipeline;
• a stock solution circulation tank receiving the stock solution transferred by the stock solution pipeline, the stock solution circulation tank being provided with a first pipeline, the first pipeline being provided with a first filter and a first pump, and the first pipeline allowing the stock solution to flow out from the stock solution circulation tank, to be pressurized by the first pump, to be sent to the first filter, and to flow back to the stock solution circulation tank, so as to be circulated and filtered;
• a grinding liquid mixing tank receiving the stock solution transferred by the first pipeline and preparing a grinding liquid, the grinding liquid mixing tank being provided with a second pipeline and a maglev stirrer, the second pipeline being provided with a second filter and a second pump, the second pipeline allowing the grinding liquid to flow out from the grinding liquid mixing tank, to be pressurized by the second pump, to be sent to the second filter, and to flow back to the grinding liquid mixing tank, so as to be circulated and filtered, and the maglev stirrer being configured at a bottom of the grinding liquid mixing tank with an inclination angle of 15-25 degrees with respect to a horizontal line;
• a grinding liquid supplying tank receiving the grinding liquid transferred by the second pipeline, the grinding liquid supplying tank being provided with an output pipeline, the output pipeline being provided with at least one output pump and a diverting valve box, the output pipeline allowing the grinding liquid to flow out from the grinding liquid supplying tank, to be pressurized by the output pump, to be sent to the diverting valve box, and to be output in a diverting manner;
• and
• a plurality of capacitive liquid level sensors, the stock solution circulation tank, the grinding liquid mixing tank, and the grinding liquid supplying tank being each connected in parallel with one capacitive liquid level sensor of the plurality of capacitive liquid level sensors, and the capacitive liquid level sensor detecting a liquid level of a liquid in the respective connected tank and monitoring whether the liquid level is normal in the connected tank.
