Description

Technical Field

[0001] This utility model relates to the technical field of mining machinery sorting equipment, specifically a quick-change wear-resistant lining heavy medium cyclone separator. Background Technology

[0002] As is well known, a heavy medium hydrocyclone is a high-efficiency coal preparation device that uses heavy suspensions or heavy liquids as the medium and relies on its own structure and external operating parameters to separate light and heavy products in a centrifugal field and a density field. Because the internal material rotates at high speed during operation, it causes combined wear on the inner wall, including micro-cutting, fatigue, and corrosion. Therefore, wear-resistant linings are used to improve service life and ensure separation accuracy.1 Quick-change components are devices designed for vulnerable parts of heavy medium hydrocyclones, such as wear-resistant linings. They enable rapid disassembly and installation of linings and other components during equipment maintenance, reducing downtime and improving production efficiency.

[0003] The quick-change assembly for the wear-resistant liner of a heavy medium hydrocyclone consists of the liner body and fixing and connecting components. Commonly used materials for the liner body include silicon carbide, wear-resistant ceramics, and polyurethane rubber. Silicon carbide has a high hardness, second only to diamond, and possesses excellent properties such as high strength, corrosion resistance, wear resistance, and high temperature resistance. The fixing and connecting components are used to externally grip the liner body, securing it inside the hydrocyclone.

[0004] In the existing technology, some quick-replacement components for wear-resistant liners of heavy medium hydrocyclones require a lot of time to disassemble and fix using bolts, making it difficult to meet the needs of quick replacement. They are also difficult to use with conventional tools, requiring the use of special small or bending tools, which makes operation difficult and may be inconvenient due to limited space, thus prolonging the disassembly time. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a quick-change wear-resistant liner heavy medium cyclone separator with a simple structure, short disassembly time, fast replacement, and convenient operation.

[0006] The technical solution adopted by this utility model to solve its technical problem is:

[0007] A quick-change wear-resistant lined heavy medium cyclone includes a conical shell and a cylindrical shell, with liners inserted into the inner walls of the conical and cylindrical shells. The conical and cylindrical shells are connected via a detachable connection assembly, which includes a connecting ring and a quick-release compression fitting. The upper and lower sides of the inner end of the connecting ring are respectively sealed to the liners of the conical and cylindrical shells, and the upper and lower sides of the outer end of the connecting ring are detachably connected to the outer walls of the conical and cylindrical shells via quick-release compression fittings.

[0008] The upper and lower sides of the inner wall of the connecting ring of this utility model are respectively fixedly connected to pressure rings, and the outer wall of the pressure ring is fixedly connected to the connecting ring via a connecting plate.

[0009] The present invention provides a sealing ring between the pressure ring and the inner liner. The two ends of the sealing ring are in contact with the ends of the pressure ring and the inner liner, respectively. The pressure ring compresses the sealing ring, thereby achieving a seal between the sealing ring and the pressure ring, and finally achieving a seal between the connecting ring and the inner liner.

[0010] The connecting ring on the outer side of the connecting plate of this utility model is fixedly connected to the docking plate, and the inner wall of the cylindrical shell or cylindrical shell on the outer side of the inner liner is provided with a docking slot. The connecting ring docks with the cylindrical shell or cylindrical shell through the corresponding insertion of the docking plate and the docking slot.

[0011] The quick-release compression connector of this utility model includes a base, a protective cover, a fixing block, a pull-out plate, a limiting plate, a guide plate, a push plate, a push rod, a pressing plate, a guide limiting plate, a return spring, and a pull-back spring. The base is fixed to the outer wall of the conical shell and the cylindrical shell. The base is covered with a protective cover, and both ends of the protective cover are respectively provided with pressing holes and pull-out holes. The fixing block is fixedly connected to the outer wall of the connecting ring. One end of the pull-out plate is fixedly connected to the fixing block, and the other end of the pull-out plate extends into the interior of the protective cover through the pull-out hole. Both sides of the pull-out plate extending into the protective cover are respectively provided with snap-fit ​​grooves. A guide limiting plate is installed inside the protective cover, and a limiting slide rail is installed on the guide limiting plate to limit movement. One end of the guide plate is symmetrically connected to the slide rail, and the other end of the guide plate is fixed with a limiting block. The limiting block is inserted into the corresponding slot. The guide plates symmetrically arranged on the slide rail are connected by a pull-back spring. A push-opening plate is provided between the guide plates. The rear end of the push-opening plate is connected to a push rod. The push rod extends out of the pressing hole and is connected to the pressing plate. A return spring is sleeved on the push rod. One end of the return spring is fixedly connected to the push rod via a limiting ring. The other end of the return spring is fixedly connected to the inner wall of the cover. By pushing the pressing plate, the pressing plate drives the push rod to push the push-opening plate. The push-opening plate pushes the two guide plates apart, thereby causing the limiting block to disengage from the slot of the pull-out plate, and thus the pull-out plate is pulled out from the cover.

[0012] The push plate of this utility model has guide arc surfaces at both ends of the contact part with the guide plate, which facilitates the push plate to be inserted between the two guide plates to unfold the two guide plates.

[0013] This utility model, due to the above-mentioned structure, has the advantages of simple structure, short disassembly time, quick replacement, and convenient operation. Attached Figure Description

[0018] The present invention will be further described below with reference to the accompanying drawings:

[0019] As shown in the attached figure, a quick-change wear-resistant lined heavy medium hydrocyclone includes a conical shell 1 and a cylindrical shell 21. A liner 19 is inserted into the inner wall of the conical shell 1 and the cylindrical shell 21. The conical shell 1 and the cylindrical shell 21 are connected via a detachable connection assembly, which includes a connecting ring 2 and a quick-release compression joint. The upper and lower sides of the inner end of the connecting ring 2 are respectively sealed to the liner 19 of the conical shell 1 and the cylindrical shell 21. The upper and lower sides of the outer end of the connecting ring 2 are respectively detachably connected to the outer wall of the conical shell 1 and the cylindrical shell 21 via quick-release compression joints. The feed pipe of the hydrocyclone is located on the upper side of the cylindrical shell, the overflow pipe is located on the upper end face of the cylindrical shell, and the bottom outlet is located at the bottom of the conical shell. Other structures and connection methods of the hydrocyclone are the same as in the prior art and will not be described in detail here.

[0020] Furthermore, pressure rings 17 are fixedly connected to the upper and lower sides of the inner wall of the connecting ring 2, and the outer wall of the pressure ring 17 is fixedly connected to the connecting ring 2 via the connecting plate 16.

[0021] Furthermore, a sealing ring 18 is provided between the pressure ring 17 and the inner liner 19. The two ends of the sealing ring 18 are in contact with the ends of the pressure ring 17 and the inner liner 19, respectively. The pressure ring 17 compresses the sealing ring 18, thereby achieving a seal between the sealing ring 18 and the pressure ring 17, and finally achieving a seal between the connecting ring 2 and the inner liner 19.

[0022] Furthermore, a docking plate 20 is fixedly connected to the connecting ring 2 on the outer side of the connecting plate 16, and a docking slot is provided on the inner wall of the cylindrical shell 1 or cylindrical shell 21 on the outer side of the liner 19. The connecting ring 2 docks with the cylindrical shell 1 or cylindrical shell 21 through the corresponding insertion of the docking plate 20 and the docking slot.

[0023] Furthermore, the quick-release compression connector includes a base 3, a protective cover 4, a fixing block 5, a pull-out insert 6, a limiting insert 7, a guide plate 8, a push-open plate 15, a push rod 11, a pressing plate 14, a guide limiting plate 10, a return spring 12, and a pull-back spring 9. The base 3 is fixed to the outer wall of the conical shell 1 and the cylindrical shell 21. The base 3 is covered with a protective cover 4, and both ends of the protective cover 4 are respectively provided with pressing holes and pull-out holes. The fixing block 5 is fixedly connected to the outer wall of the connecting ring 2. One end of the pull-out insert 6 is fixedly connected to the fixing block 5, and the other end of the pull-out insert 6 extends into the interior of the protective cover 4 through the pull-out hole of the protective cover 4. The two sides of the pull-out insert 6 extending into the interior of the protective cover 4 are respectively provided with snap-fit ​​grooves. The guide limiting plate 10 is installed inside the protective cover 4, and a limiting slide rail is installed on the guide limiting plate 10. One end of the sliding connecting guide plate 8 is fixed with a limiting plug 7 at the other end. The limiting plug 7 is inserted into the corresponding slot. The guide plates 8, which are symmetrically arranged with limiting slide rails, are connected by a return spring 9. A push plate 15 is provided between the guide plates 8. The rear end of the push plate 15 is connected to the push rod 11. After the push rod 11 extends out of the pressing hole, it is connected to the pressing plate 14. A return spring 12 is sleeved on the push rod 11. One end of the return spring 12 is fixedly connected to the push rod 11 via a limiting ring 13. The other end of the return spring 12 is fixedly connected to the inner wall of the cover 4. By pushing the pressing plate 14, the pressing plate 14 drives the push rod 11 to push the push plate 15. The push plate 15 pushes the two guide plates 8 apart, thereby causing the limiting plug 7 to disengage from the slot of the pull-out insert plate 6, and thus the pull-out insert plate 6 is pulled out from the cover 4.

[0024] Furthermore, the push plate 15 has guide arc surfaces at both ends of the contact portion with the guide plate 8, which facilitates the insertion of the push plate 15 between the two guide plates 8 to unfold the two guide plates 8.

[0025] When disassembling this utility model, pushing the pressing plate 14 causes the push rod 11 to push the push plate 15. The push plate 15 pushes the two guide plates 8 apart, thereby causing the limiting insert 7 to disengage from the snap-fit ​​groove of the pull-out insert 6, and then the pull-out insert 6 is pulled out from the protective cover 4. Finally, the connecting ring 2 and the cylindrical shell 1 and cylindrical shell 21 are pulled out. After being pulled out, the inner liner 19 of the cylindrical shell 1 and cylindrical shell 21 can be replaced. After replacement, reassembly is performed. During reassembly, the mating insert 20 on the connecting ring 2 is inserted into the mating slot of the cylindrical shell 1 or cylindrical shell 21. At the same time, the pull-out insert 6 is inserted into the inside of the protective cover 4 through the pull-out hole on the protective cover 4. The pressure ring 17 compresses the cone shell 1 and the cylindrical shell 21 respectively, while the pressure ring 17 compresses the sealing ring 18, thereby achieving a seal between the sealing ring 18 and the pressure ring 17, and finally achieving a seal between the connecting ring 2 and the inner liner 19. While compressing, the pressing plate 14 is pushed, and the pressing plate 14 drives the push rod 11 to push the push plate 15. The push plate 15 pushes the two guide plates 8 open, and the pull-out insert 6 is inserted between the two guide plates 8. When pushed to the snap-fit ​​groove position, the pressing plate 14 rebounds and resets under the action of the return spring 12. The guide plates 8 move towards each other under the action of the return spring 9, thereby inserting the limiting insert 7 connected to the guide plate 8 into the snap-fit ​​groove, thus completing the installation.

[0026] The above solution improves upon the existing technology, which uses bolts for disassembly and fixing, requiring considerable time and making it difficult to meet the needs of rapid replacement. It also addresses the limitations of conventional tools, requiring specialized small or bending tools, which increase operational difficulty and may be further hampered by confined spaces, thus extending disassembly time. The above solution achieves rapid disassembly, significantly reduces equipment downtime, and substantially improves production efficiency. This reduces worker labor intensity and equipment wear, facilitates equipment maintenance and management, and effectively prevents media leakage, avoiding resource waste and environmental pollution, thereby ensuring a safe production environment. Due to its structure, this invention offers advantages such as simple structure, short disassembly time, rapid replacement, and convenient operation.
