Description

Technical Field

[0001] This utility model relates to the technical field of raw coal washing and beneficiation equipment, and in particular to a durable three-product hydrocyclone. Background Technology

[0002] The heavy medium pressureless three-product hydrocyclone is the "heart" of heavy medium coal preparation. During the washing of raw coal, the raw coal is driven to rotate at high speed by the side-feed heavy medium liquid inside the hydrocyclone, and the Archimedes principle can be used to separate clean coal and other by-products. However, since the clean coal section of the three-product hydrocyclone is integrated, the raw material will continuously scour a certain part at the feed inlet of the hydrocyclone, which will easily wear through and leak material, thus rendering the entire hydrocyclone unusable. In order to improve the service life of the hydrocyclone, this application proposes a durable three-product hydrocyclone. Utility Model Content

[0003] To address the above issues and overcome the shortcomings of existing technologies, this utility model provides a durable three-product hydrocyclone. The technical solution it provides includes a hydrocyclone body, characterized in that a docking flange is coaxially fixedly connected to the inlet of the hydrocyclone body, and a corresponding inlet short pipe is arranged at the inlet of the hydrocyclone body. A live flange, rotatably connected to the outlet end of the inlet short pipe, is coaxially fitted with the live flange. The live flange and the docking flange are connected by bolts. Three limiting rods, evenly distributed along their semi-circumference, are fixedly connected to the outer edge of the inlet short pipe. Each limiting rod has a limiting ring fixedly connected to its end. A sleeve is fixedly connected to the live flange. A rod that inserts into the limiting ring is coaxially movably fitted onto the sleeve. A guide groove parallel to the axis of the sleeve is formed on its side wall. A guide rod that slidably connects to the guide groove is fixedly connected to the outer edge of the rod. A threaded sleeve is fixedly connected to the outer end of the guide rod. A screw threadedly connected to the threaded sleeve is rotatably connected to the live flange.

[0004] Preferably, the screw is coaxially fixedly connected to a dial.

[0005] Preferably, the insertion rod has a rounded corner at one end outside the sleeve.

[0006] The beneficial effects of this utility model are:

[0007] This application divides the traditional integrated hydrocyclone into two parts: the hydrocyclone body and the feed inlet short pipe. A live flange connects the feed inlet short pipe to the hydrocyclone body, facilitating periodic disassembly and maintenance. The feed inlet short pipe can be adjusted according to its wear level caused by erosion; rotating it 1 / 4 or 1 / 2 turn as needed replaces the eroded sections, ensuring the wear-resistant layer thickness meets requirements and preventing complete failure due to localized damage. This significantly extends the service life of the hydrocyclone, greatly increasing its lifespan. It achieves the goal of periodically inspecting and replacing the feed inlet short pipe without replacing the entire body, significantly reducing maintenance costs and time.

[0015] The following is in conjunction with the appendix Figure 1-5 The specific embodiments of this utility model will be described in further detail.

[0016] In embodiment one, the technical solution is as follows: In use, the traditional integrated hydrocyclone is divided into two parts: the hydrocyclone body 1 and the feed short pipe 3. A live flange 4 connects the feed short pipe 3 to the hydrocyclone body 1, facilitating periodic disassembly and maintenance of the feed short pipe 3. Simultaneously, the feed short pipe 3 can be adjusted according to the degree of wear caused by erosion. Rotating the feed short pipe 3 by 1 / 4 or 1 / 2 turn as needed can replace the eroded parts, ensuring the wear-resistant layer thickness of these areas meets usage requirements. This avoids the complete scrapping of the hydrocyclone due to localized damage, significantly extending the service life and lifespan of the hydrocyclone. It achieves the goal of periodically inspecting and replacing the feed short pipe without replacing the entire body, greatly reducing maintenance costs and shortening maintenance time.

[0017] In Example 2, based on Example 1, specifically, when this application is in use, the feed inlet of the hydrocyclone body 1 is provided with a docking flange 2. The docking flange 2 is connected to the feed short pipe 3 by bolts 5 and a live flange 4, which facilitates the disassembly and maintenance of the feed short pipe 3. In order to prevent the feed short pipe from rotating automatically during normal use, a plug rod 9 and a limiting ring 7 are also provided to limit the automatic rotation of the feed short pipe 3 when it is not necessary.

[0018] The live flange 4 is rotatably connected to the inlet short pipe 3, which allows for easy rotation of the inlet short pipe 3 to change the position of the inlet short pipe 3 subject to scouring. When it is necessary to change the position of the inlet short pipe 3 subject to scouring, first release the insertion rod 9 from the limit switch. Specifically, rotate the screw 13 counterclockwise. To facilitate the rotation of the screw 13, a dial 14 is provided at its end. The counterclockwise rotation of the screw 13 will drive the guide rod 11 through the screw sleeve 12. The guide rod 11 is restricted by the guide groove 10. Therefore, under the action of the counterclockwise rotation of the screw 13, the guide rod 11 will move along the guide groove 10 towards the bottom of the sleeve 8. Then, the insertion rod 9, which is fixedly connected to the guide rod 11, will move into the sleeve 8 simultaneously. Then, the insertion rod 9 will disengage from the limit ring 7 at the end of the limit rod 6. The insertion rod 9 disengages from the limit ring 7 and enters the sleeve 8. The feed short pipe 3 is restricted, allowing it to rotate relative to the live flange 4. Depending on the wear of the feed short pipe 3, it can be rotated clockwise by 1 / 4 or 1 / 2 turn. After rotation, one of the other two limiting rings 7 will correspond to the insertion rod 9. Then, the screw 13 is rotated clockwise via the dial 14. The clockwise rotation of the screw 13 will drive the guide rod 11 through the screw sleeve 12. Under the restriction of the guide groove 10, the guide rod 11 will move out of the sleeve 8 together with the insertion rod 9. The insertion rod 9 can then be inserted into the limiting ring 7 corresponding to it, thus restricting the feed short pipe 3 from rotating automatically when not necessary.

[0019] In Example 3, based on Example 2, the insertion end of the insertion rod 9 and the limiting ring 7 is provided with a rounded corner 15 to facilitate its insertion and engagement with the limiting ring 7.
