The advantages of low construction cost, low operation energy consumption and high equipment operation efficiency are achieved.

[0059] By setting up the slurry adjustment synchronous drive device, the pressure switching device and the water injection device, the zinc ore slurry adjustment tank 12, the zinc ore flash tank 14 and the zinc ore filter press 15 are spatially corresponding to the lead ore slurry adjustment tank 21, the lead ore flash tank 23 and the lead ore filter press 24 respectively, thereby realizing the parallel setting of the zinc ore processing subsystem and the lead ore processing subsystem, making the spatial position setting of the system more reasonable and compact, and the position and processing flow of each equipment more intuitive, which is convenient for operators to observe and operate.

[0060] When the air pump 46 draws out the air in the first connecting pipe 41, negative pressure is generated in the first air storage tank 47, so that air can be sucked in through the first air storage tank 47, ensuring that the air pressure in the zinc ore flash tank 14 and the lead ore flash tank 23 is stably maintained at a low state, thereby ensuring the flash evaporation effect of the zinc ore and the lead ore.

[0062] The water in the water reservoir 61 is respectively input into the first piston sleeve 54 and the second piston sleeve 56 through the first water inlet pipe 62 and the second water inlet pipe 64. The double-rod oil cylinder 53 drives the first piston plate 55 to move toward the first water injection port 51 and drives the second piston plate to move in a direction away from the second water injection port 52. The first water valve 63 is closed and the second water valve 65 is opened, so that the water in the first piston sleeve 54 can be pressed into the first water injection port 51 through the first piston plate 55, and the movement of the second piston plate 57 causes the water in the water reservoir 61 to be sucked into the second piston sleeve 56.
