The ore pulp is injected into the second feeding cylinder 15 through the feeding pipe 16, and the ore pulp is input into the conical classifier 10 through the first feeding cylinder 14.

[0036] Specifically as shown in the drawings, Figure 1 , Figure 4 , Figure 5 and Figure 6As shown, the bottom of the conical classifier 10 is fixedly installed with a discharge hopper 17, the bottom of the discharge hopper 17 is provided with a discharge valve 18, the inside of the discharge hopper 17 is provided with two groups of holes, one group of high-pressure water pipes 20 and one group of sand pipes 21 are respectively fixedly installed in the holes, and the outer wall of the high-pressure water pipe 20 is provided with a high-pressure water valve 19.

[0041] Working principle: The device monitors the liquid level inside the conical classifier in real time through the monitoring structure. The monitoring part is composed of a first L-shaped pipe 22 and a second L-shaped pipe 23, both of which are transparent pipes for easy observation. One end of the first L-shaped pipe 22 extends into the classifier, and the other end is connected to the control valve 24, while the second L-shaped pipe 23 is completely outside the classifier and is connected to the other end of the control valve 24. When the liquid level inside the classifier rises, the liquid will enter the second L-shaped pipe 23 through the first L-shaped pipe 22, and the liquid level in the second L-shaped pipe 23 can be observed to determine the liquid level inside the classifier. If the liquid level needs to be adjusted, the flow of liquid can be controlled by opening and closing the control valve 24, thereby raising or lowering the liquid level. The ore pulp is injected into the second feed cylinder 15 through the feed pipe 16, and then enters the conical classifier 10 inside the first feed cylinder 14. This design ensures that the ore pulp can enter the classifier smoothly and uniformly, providing favorable conditions for subsequent classification processing. When the liquid level inside the classifier exceeds a certain height, the excess liquid will be discharged through the annular overflow groove plate 11 and the overflow pipe 12 to prevent the liquid from overflowing the classifier. The classified ore pulp and sand are discharged through different channels of the discharge hopper 17. The discharge hopper 17 is equipped with a high-pressure water pipe 20 and a sand pipe 21. The high-pressure water pipe 20 can be used to flush the inside of the classifier or assist in discharging, while the sand pipe 21 is specifically used to discharge larger particles deposited at the bottom. Opening the discharge valve 18, the classified ore pulp can be discharged through the discharge hopper 17. The universal wheel 26 installed at the bottom of the support platform 25 allows the entire device to be easily moved and transferred between different work sites.
