The powder drying device for LATP electrolyte preparation is provided with a collection tank, a supporting plate, a weighing sensor, an LED indicator, and a USB interface. When in use, as the amount of powder in the collection tank increases, the pressure exerted on the weighing sensor by the supporting plate also gradually increases. When the pressure of the weighing sensor exceeds the preset threshold, the LED indicator changes from green to red. The staff can then remove the collection tank for cleaning. The lithium battery provides energy support for the operation of the weighing sensor and the LED indicator, thereby realizing the full-quantity reminding function and solving the problem that the device does not have the full-quantity reminding function.

[0004] However, in the above-mentioned scheme and the prior art, LIFSI, as a solid-state electrolyte powder, needs to be collected by a material receiving device during the preparation process. The material receiving device works to achieve suction and air intake, and then the suction head at the end of the suction tube generates suction force to collect LIFSI. When the material receiving device is not in operation, a protective cover is screw-connected to the end of the suction head to prevent foreign matter from entering the suction head and the suction tube, which affects the subsequent collection of LIFSI. The protective cover at the end of the suction head is easily lost when LIFSI is sucked, which affects the effect of preventing foreign matter. Therefore, improvement and optimization are needed.
