[0014] The electrolyte storage bins 4 are divided into two storage bins 4 of different particle sizes, and two storage bins 4 of each particle size are provided. Each outlet of the vibrating screen 3 is connected to two storage bins 4 of the same particle size through an electro-hydraulic three-way distributing valve 2. The particle size of the electrolyte is divided into two specifications, namely 0-3 mm and 3-15 mm, wherein two storage bins 4 of 0-3 mm electrolyte are provided, and two storage bins 4 of 3-15 mm electrolyte are provided. The vibrating screen 3 is provided with two outlets of different particle sizes, wherein outlet A is connected to the storage bin 4 of 0-3 mm correspondingly, and outlet B is connected to the storage bin 4 of 3-15 mm correspondingly, and an electro-hydraulic three-way distributing valve 2 is provided at outlet A and outlet B respectively, wherein the electro-hydraulic three-way distributing valve 2 of outlet A is connected to two storage bins 4 of 0-3 mm respectively, and the electro-hydraulic three-way distributing valve 2 of outlet B is connected to two storage bins 4 of 3-15 mm respectively. This arrangement ensures that the storage bin 4 can store a large amount of electrolyte, and the storage volume can meet the mixing requirements.

[0015] The bucket elevator 1 and the vibrating screen 3 are each provided with 2 sets, and 4 electrolyte storage bins 4 are provided correspondingly, of which 2 are provided for the electrolyte storage bins 4 of 0-3 mm, and 2 are provided for the electrolyte storage bins 4 of 3-15 mm, and these 4 electrolyte storage bins 4 share 1 set of screw conveyor 6, and the corresponding double-shaft mixing and stirring conveyor 8 is also provided with only 1 set. The reason for providing 2 sets of bucket elevators 1 and 2 sets of vibrating screens 3 is to improve the storage and transportation efficiency of the electrolyte and ensure that the storage amount of the electrolyte meets the subsequent mixing usage requirements.

Unloading: The stirred material is transported to the electrolyte transport vehicle 12 through the telescopic joint device 11, and the electrolyte transport vehicle 12 transports the material to the covering material conveying system next to the electrolysis workshop.
