[0002] The hydrocyclone for beneficiation plays an important role in the beneficiation process, and its working principle is based on the synergistic action of centrifugal force and gravity. The pulp enters the hydrocyclone along the tangential direction under pressure, forming a high-speed rotating liquid flow. Under the action of centrifugal force, particles with different particle sizes and densities will be subjected to different forces, so as to achieve separation.

However, during beneficiation, due to the presence of large particles, debris or viscous substances in the pulp, they are likely to accumulate at the feeding port and cause blockage. Moreover, the hydrocyclone of this prior art is not equipped with a blockage clearing mechanism. Seriously, it needs to be disassembled and cleaned. The blockage clearing work is laborious and greatly affects the beneficiation efficiency. In view of this, a hydrocyclone for beneficiation is provided. Summary of the Utility Model

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] The front, back, left, right, top and bottom in this embodiment are described with Figure 1 as the reference plane. Please refer to Figures 1-5 , the present utility model provides a technical solution:

[0022] A hydrocyclone for ore dressing includes a hydrocyclone main body 1. An inlet pipe 11 and an overflow pipe 12 are respectively arranged on the outer surface and the upper surface of the hydrocyclone main body 1. A bottom flow pipe 13 is arranged at the bottom of the hydrocyclone main body 1. A connecting pipe 2 is detachably installed between the bottom flow pipe 13 and the blanking end of the hydrocyclone main body 1. A water flushing mechanism is arranged in the connecting pipe 2;

[0023] It should be noted that an installation groove 22 is opened on the inner cavity side wall of the connecting pipe 2. Two through ports 26 are penetrated in the installation groove 22. The water flushing mechanism includes two annular pipes 3. The annular pipes 3 are fixedly installed in the installation groove 22. The water inlet ends of the two annular pipes 3 penetrate through the corresponding through ports 26. A three-way water supply pipe 4 is connected between the water inlet ends of the two annular pipes 3. The three-way water supply pipe 4 is connected to an external high-pressure water supply device for use. A plurality of sprinkler heads 31 are equidistantly installed on the outer surface of the annular pipe 3. The spraying direction of the upper sprinkler head 31 is upward, and the spraying direction of the lower sprinkler head 31 is downward;

[0024] When the blockage needs to be cleared, high-pressure water can be injected into the two annular tubes 3 through the three-way water supply pipe 4 using external high-pressure water supply equipment. The water is sprayed out from the corresponding nozzles 31 to perform high-pressure flushing on the blocked sticky mud. The mud is dispersed and falls naturally, and the material can flow smoothly in the underflow pipe 13, thereby solving the blockage problem in the underflow pipe 13 and ensuring that the blockage unblocking operation can be performed without disassembling the underflow pipe 13. Compared with the prior art, the cleaning efficiency is high and the mineral processing efficiency is not affected.

[0025] In order to ensure that the annular tube 3 can be smoothly installed in the connecting tube 2, the annular tube 3 needs to be set as an annular hose. The annular hose has a certain flexibility and can be bent and placed in the installation groove 22 of the connecting tube 2 for installation.

[0026] In addition, combined Figure 2 and Figure 3 As shown, a fixing ring 23 is fixedly installed in the installation groove 22, and rubber retaining rings 24 are fixedly installed on the upper and lower surfaces of the fixing ring 23. A clamping groove 25 is formed between the rubber retaining ring 24 and the installation groove 22. The annular tube 3 is clamped and arranged in the corresponding clamping groove 25. A clamping groove A241 is provided on the side of the rubber retaining ring 24 away from the fixing ring 23. After the annular tube 3 is installed, the nozzle 31 is clamped in the corresponding clamping groove A241.

[0027] When initially installing the annular pipe 3, Figure 3 As shown, the water inlet end is first passed through the through port 26 and then clamped into the clamping groove 25. Then, the position of the nozzle 31 is adjusted and the nozzle 31 is clamped into the clamping groove A241 of the rubber retaining ring 24. The rubber retaining ring 24 is used to limit the spraying direction of the nozzle 31, and at the same time, the annular tube 3 is blocked and clamped in the clamping groove 25.

[0028] In addition, in order to further ensure the stability of the annular tube 3 when water is flowing and avoid it from being separated from the clamping groove 25, the Figure 2 , Figure 3 and Figure 4 As shown, a rubber limiting ring 5 is clamped and installed between the rubber retaining ring 24 and the mounting groove 22. An arc groove 51 is provided on the side of the rubber limiting ring 5 close to the fixing ring 23. The inner surface of the arc groove 51 fits with the outer surface of the corresponding annular tube 3. A plurality of clamping grooves B52 are uniformly arranged in the arc groove 51. The nozzle 31 is clamped in the corresponding clamping groove B52. After the rubber limiting ring 5 is installed between the rubber retaining ring 24 and the mounting groove 22, the rubber retaining ring 24 can be used to fill the idle space between the annular tube 3 and the mounting groove 22 to prevent it from being separated from the clamping groove 25, thereby ensuring the stability of the annular tube 3 when water is passing.

[0029] Specifically, combined Figure 1 and Figure 2As shown, flanges 21 are fixedly installed at both the upper and lower ends of the connecting pipe 2. The two flanges 21 are respectively fixedly connected to the cyclone body 1 and the underflow pipe 13 by bolts. When it is necessary to disassemble the connecting pipe 2, just unscrew the bolts to separate it from the cyclone body 1 and the underflow pipe 13.
