[0036] In this embodiment, the cross-shaped partition is formed by welding four steel plates in sequence, and two of them are perpendicular to each other, so that the bottom of the cylinder 100 is evenly divided into four parts, and the first feeding area 102 is corresponding to the second feeding area 103, and the first discharge area 104 is corresponding to the second discharge area 105. In another embodiment, the steel plates are welded by "7"-shaped steel plates, and the wider sides of the four steel plates are welded together perpendicularly, and the narrower sides are welded to the cylinder 100, so that gaps are formed between the various areas to facilitate the overflow of the ore liquid.

[0040] Further, the first adjusting member includes a first fixing frame 300, a first screw rod 301, a first rotating wheel 302 and a first cone valve 303, wherein the first fixing frame 300 is arranged on the cylinder 100, the first rotating wheel 302 is rotatably connected to the first fixing frame 300, the first screw rod 301 is threadedly connected to the first rotating wheel 302 and passes through the fixing frame and is fixedly connected to the first cone valve 303, the first cone valve 303 is used to close the first discharge port, and the first rotating wheel 302 is used to drive the first screw rod 301 to move and then drive the first cone valve 303 to move up and down, so as to adjust the opening of the first discharge port.

The second cone valve 403 is used to close the second discharge port, and the second rotating wheel 402 is used to drive the second screw rod 401 to move and then drive the second cone valve 403 to move up and down, so as to adjust the opening of the second discharge port.

[0042] In this embodiment, when in use, the second screw rod 401 is moved upward or downward by rotating the second rotating wheel 402, thereby driving the second cone valve 403 to move upward or downward.

When the slurry needs to be distributed to the two slurry pipes 500 more evenly, the first cone valve 303 and the second cone valve 403 are lifted up at the same time, so that the slurry flows evenly into the two slurry pipes 500. When the slurry needs to be fed into only one of the slurry pipes 500, if the first discharge port corresponding to the first adjusting member needs to distribute the slurry, the second cone valve 403 is moved to the bottom, the second cone valve 403 blocks the entrance of the second discharge port, and then the first cone valve 303 is adjusted to a high position, so that the slurry flows into the first discharge port. When it is necessary to precisely adjust the slurry flow rate fed into one of the slurry pipes 500 , one of the cone valves is fully opened, and the other cone valve adjusts the screw opening to achieve precise control of the slurry amount fed into the slurry pipe 500 .

[0043] Furthermore, sealing rubber is provided on the first cone valve 303 and the second cone valve 403. In this embodiment, sealing rubber is provided on the surfaces of the first cone valve 303 and the second cone valve 403.
