Description

Technical Field

[0001] This utility model relates to the field of hydrocyclones, and in particular to an anti-clogging hydrocyclone. Background Technology

[0002] A hydrocyclone is a device that uses centrifugal force to separate solid-liquid or liquid-liquid mixtures. It consists of a feed inlet, a cylindrical section, a conical section, an overflow pipe, and an underflow outlet. The cylindrical section provides the initial rotation space for the slurry, and its diameter determines the specifications of the hydrocyclone. The conical section is connected at the bottom, and as the diameter decreases, it accelerates the rotation of the slurry and enhances centrifugal separation. The overflow pipe is located in the center and is responsible for discharging the fine particles and feeding the ore along the tangential direction into the ore pipe, giving the slurry rotational power. The sand outlet is at the bottom of the cone and discharges coarse sand particles.

[0003] Anti-clogging hydrocyclones are hydrocyclone devices that can filter and clean. They work by using vortex centrifugal force to achieve efficient material separation, while a driving cleaning mechanism cleans key parts in real time. Combined with pre-treatment filtration, they prevent clumping and ensure continuous and stable operation of the equipment in the processing of high-viscosity and high-impurity materials. They are suitable for scenarios prone to sedimentation and clogging.

[0004] In existing technologies, hydrocyclones have shortcomings in cleaning and filtration. During cleaning, backwashing and other methods are not thorough in removing fine particles and sticky impurities, which are prone to clogging. In terms of filtration, the filter media is easily worn by the impact of large particles, resulting in a decrease in accuracy. Dead corners in the structure are prone to clogging, affecting the flow rate. The unclogging mechanism is inefficient and difficult to quickly remove stubborn particles. Therefore, an anti-clogging hydrocyclone is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an anti-clogging hydrocyclone, which aims to improve the problem of easy clogging and agglomeration in some existing devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A clog-resistant hydrocyclone includes a housing, a cyclone barrel fixedly connected to the top of the housing, a platform fixedly connected to the left side of the housing, a support block fixedly connected to the bottom of the platform, a fixing ring fixedly connected to the top of the platform, a motor fixedly connected inside the fixing ring, a rotating shaft fixedly connected to the drive end of the motor, multiple crossbars fixedly connected inside the housing, a sealing box fixedly connected to adjacent sides of the multiple crossbars, two fixing rings fixedly connected to the outside of the sealing box, a vertical rod rotatably connected inside one of the fixing rings, a bevel gear fixedly connected to the right side of the rotating shaft, multiple cleaning ropes fixedly connected to the outside of the vertical rod, and a detachable filter assembly fixedly connected to the left side of the cyclone barrel to facilitate clog prevention of the housing.

[0008] The anti-clogging detachable filter assembly of this utility model includes an inflow pipe, a plurality of fixing blocks are fixedly connected to the left side of the inflow pipe, two limiting pins are detachably connected inside the plurality of fixing blocks, lifting blocks are detachably connected to the outside of the two limiting pins, a filter block is fixedly connected to the bottom of the lifting block, and a locking pin is provided on the rear side of each of the two limiting pins. An L-shaped pipe is fixedly connected to the bottom left side of the inflow pipe, and a material plug is threadedly connected to the left side of the L-shaped pipe.

[0009] The vortex barrel of this invention is internally fixedly connected to a guide, and the inflow pipe is externally fixedly connected to the inside of the guide.

[0010] The top of the vertical rod of this utility model is fixedly connected to a second bevel gear, and the outer side of the first bevel gear and the outer side of the second bevel gear are meshed together.

[0011] The top of the vortex barrel of this utility model is fixedly connected to a cover plate, the bottom of the cover plate is fixedly connected to an overflow pipe one, and the top of the cover plate is fixedly connected to an overflow pipe two.

[0012] The outer side of the rotating shaft of this invention is rotatably connected to the inside of another fixed ring, and the right side of the support block is fixedly connected to the left side of the housing.

[0013] The L-shaped tube of this invention is fixedly connected to the top left side of a conveying pipe, the top of which is fixedly connected to the bottom of two fixed blocks, and the exterior of two limiting pins is fixedly connected to the interior of the two fixed blocks respectively.

[0014] The front and rear sides of the lifting block of this utility model are detachably connected to the adjacent side of the plurality of fixed blocks, and the right side of the filter block is in contact with the left side of the inflow pipe.

[0015] This utility model has the following beneficial effects:

[0016] 1. In this utility model, the motor drives the rotating shaft to rotate, which in turn drives the first bevel gear. The first bevel gear meshes with the second bevel gear at a right angle. The outside is fixed and sealed by a crossbar and a sealing box. The second bevel gear is connected to the vertical rod. Rotating the vertical rod drives the cleaning rope to rotate, thereby achieving the effect of cleaning the inner wall of the shell. This achieves non-fixed cleaning. Compared with the scraper setting of the prior art, it has higher expandability and stability. It will not be blocked by adhesion, and the cleaning device is more comprehensive. The cleaning rope can be increased or decreased according to actual needs. The cleaning rope has less resistance and will not have a significant impact on the eddy current inside the equipment. It is also less prone to damage.

[0017] 2. In this utility model, the filter block is connected to the inflow pipe by an inclined surface. The inclined surface guides and the flushing force of the water flow causes large particles to fall into the L-shaped pipe along the inclined surface. The L-shaped pipe acts as a collection device. With the help of the reaction force of the water flow, the particles are pushed to the material blockage. The fixed block is locked with a limit pin. After the limit pin is pulled out, the lifting block can be pulled upward to disassemble it, realizing the quick disassembly and assembly of the filter block. This achieves accurate filtration of raw materials, ensures accurate and effective separation of materials, automatically guides and intercepts particles, prevents the filter components from clogging, maintains continuous operation of the equipment, simplifies the waste cleaning and filter block replacement process, reduces maintenance costs, and improves equipment operating efficiency.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Reference Figure 1 , Figure 3 and Figure 5 This utility model provides an embodiment of an anti-clogging hydrocyclone, including a shell 1, which serves as the basic load-bearing structure of the device. A cyclone barrel 2 is fixedly connected to the top of the shell 1, serving as the outer shell for initial cyclone feeding. A platform 11 is fixedly connected to the left side of the shell 1, which provides an installation reference surface for a motor 14. A support block 12 is fixedly connected to the bottom of the platform 11. The support block 12 is a cuboid structure, which ensures the verticality of the motor 14 installation, stably supports the weight of the motor 14 during operation, and reduces the vibration transmission of the motor 14 during operation. A fixing ring 13 is fixedly connected to the top of the platform 11. The fixing ring 13 is an annular structure, which serves to fix the motor 14 on the platform 11. The motor 14 is fixedly connected inside the fixing ring 13. The motor 14 drives the rotating shaft 15 to rotate through the torque output from the drive end, thereby driving the operation of the entire cleaning mechanism. The rotating shaft 15 is fixedly connected to the drive end of the motor 14, which is an important component of the transmission and then connects to the bevel gear 20 to rotate.

[0027] The housing 1 has four crossbars 16 fixedly connected internally, each at a right angle to the inner wall of the housing 1. A sealing box 17 is fixedly connected to adjacent sides of the crossbars 16, and is fixed to the center of the housing 1 via the crossbars 16. The sealing box 17 can be made of rust-proof material. During equipment operation, the sealing box 17 prevents impurities and moisture from entering and affecting the operation of its internal components. It also serves to prevent displacement of the first bevel gear 20 and the second bevel gear 21 during rotation. The sealing box 17 has two fixing rings 27 fixedly connected externally, each fitted onto one side of the sealing box 17 to ensure its sealing and provide support for the rotation of the internal vertical rod 18. The device is in operation. One of the fixed rings 27 is internally connected to a vertical rod 18, which serves as the operating component of the cleaning device and drives the cleaning rope 19 to clean. A bevel gear 20 is fixedly connected to the right side of the rotating shaft 15. The bevel gear 20 meshes with the bevel gear 21 on the vertical rod 18, causing the vertical rod 18 to rotate. Multiple cleaning ropes 19 are fixedly connected to the outside of the vertical rod 18. The cleaning ropes 19 serve as the final device in the entire cleaning assembly and can be made of steel wire or rigid nylon rope to clean the clumps on the inner wall of the housing 1 and the bottom low flow port. In particular, the clumps or blockages in the low flow port can be quickly cleared and cleaned. A detachable filter assembly is fixedly connected to the left side of the vortex bucket 2 to prevent the housing 1 from clogging.

[0028] Reference Figure 1 , Figure 2 and Figure 4The anti-clogging detachable filter assembly includes an inlet pipe 4, which serves as the outlet of the anti-clogging filter device. Multiple fixing blocks 22 are fixedly connected to the left side of the inlet pipe 4. There are four fixing blocks 22 in total, which are connected to the inlet pipe 4 to form a stable support structure. They are like solid fulcrums. Two limiting pins 23 are detachably connected inside the multiple fixing blocks 22. The detachable connection of the limiting pins 23 greatly facilitates the maintenance and replacement of the filter assembly. When the filter assembly needs to be cleaned or repaired, the limiting pins 23 can be removed from the fixing blocks 22 to carry out subsequent operations.

[0029] Lifting blocks 24 are detachably connected to the outer sides of the two limiting pins 23. The lifting blocks 24 provide a convenient operating point for the removal and installation of the filter block 26. Operators can easily remove or insert the filter block 26 from the inflow pipe 4 by lifting the lifting blocks 24. The filter block 26 is fixedly connected to the bottom of the lifting blocks 24. The filter block 26 is a key component for the entire filter assembly to achieve its filtration function. When the medium to be filtered flows through the inflow pipe 4, it first passes through the filter block 26. The filter block 26 can effectively intercept impurities and particulate matter in the medium, preventing these impurities from entering subsequent pipes or equipment, thereby playing a role in preventing blockage. A locking pin 25 is provided on the rear side of each of the two limiting pins 23. The locking pin 25 is set on the rear side of the limiting pin 23 to prevent the limiting pin 23 from falling off due to vibration during equipment use. An L-shaped pipe 6 is fixedly connected to the bottom left side of the inflow pipe 4. One end of the L-shaped pipe 6 is connected to the bottom left side of the inflow pipe 4, and the other end extends to the left to form a receiving channel. This channel is mainly used to discharge larger impurities during the filtration process. A material plug 7 is threadedly connected to the left side of the L-shaped pipe 6. The material plug 7 can tightly seal the left end outlet of the L-shaped pipe 6. When the filter assembly is working normally, the material plug 7 is in the closed state to prevent the medium from leaking from the L-shaped pipe 6. When it is necessary to clean the impurities in the L-shaped pipe 6 or drain the accumulated liquid, simply unscrew the material plug 7, and the impurities and accumulated liquid can be discharged.

[0030] Reference Figure 2 , Figure 3 and Figure 5Inside the swirl tank 2, a guide 9 is fixedly connected. The guide 9 is laid along the swirl tank 2. When the material flows out from the inlet pipe 4, it will guide the material into a spiral flow trajectory, avoiding the material from directly impacting the tank wall and causing turbulence. The outside of the inlet pipe 4 is fixedly connected to the inside of the guide 9. The outlet of the inlet pipe 4 is directly facing the inner groove of the guide 9. The two work together like a baton exchange in a relay race, allowing the material to form a stable rotation the moment it enters the swirl tank 2. The top of the vertical rod 18 is fixedly connected to a bevel gear 21. The bevel gear 21 and the bevel gear 1 20 form a transmission ratio. The outside of the bevel gear 1 20 and the outside of the bevel gear 21 are meshed. When the bevel gear 1 20 rotates under the drive of an external force, it transmits the power to the bevel gear 21. The original horizontal rotational force is transformed into a vertical driving force here. The vertical rod 18 then rises or rotates synchronously with the rotation of the bevel gear 21.

[0031] A cover plate 3 is fixedly connected to the top of the cyclone tank 2. The cover plate 3 is firmly sealed on the top of the cyclone tank 2, which not only prevents the material inside the tank from splashing out when rotating at high speed, but also maintains the pressure inside the tank. An overflow pipe 1 8 is fixedly connected to the bottom of the cover plate 3. The overflow pipe 1 8 extends into the inside of the cyclone tank 2 from the bottom of the cover plate 3, and is specifically used to collect light materials near the center during the rotation. An overflow pipe 2 10 is fixedly connected to the top of the cover plate 3. The overflow pipe 2 10 stands upright on the top of the cover plate 3 and is responsible for discharging impurities or liquids with lower density after preliminary separation. The outer side of the rotating shaft 15 is rotatably connected to the inside of another fixed ring 27. The fixed ring 27 functions similarly to a bearing, encircling the rotating shaft 15 in the middle. The right side of the support block 12 is fixedly connected to the left side of the housing 1. The support block 12 provides support for the platform 11, making the motor 14 above it more stable.

[0032] The top left side of the L-shaped pipe 6 is fixedly connected to the conveying pipe 5, which serves as the initial channel for transporting materials. The top of the conveying pipe 5 is fixed to the bottom of two fixed blocks 22. The fixed blocks 22 are connected to the conveying pipe 5 to form a disassembled filtration device. The exterior of the two limiting pins 23 are respectively fixedly connected to the interior of the two fixed blocks 22. After the limiting pins 23 pass through the holes of the fixed blocks 22, they firmly lock the adjacent fixed blocks 22 to prevent them from shifting during equipment operation. The front and rear sides of the lifting block 24 are detachably connected to the adjacent side of multiple fixed blocks 22. The lifting block 24 and the filter block 26 are connected and locked in multiple fixed blocks 22, and the limiting pins 23 limit the disassembly. The right side of the filter block 26 is in contact with the left side of the inflow pipe 4. The filter block 26 blocks the entrance of the inflow pipe 4. When the material moves from the left side to the inflow pipe 4, it will first perform preliminary screening of the material.

[0033] Working principle: During cleaning, the motor 14 above the platform 11 drives the rotating shaft 15 to rotate. A sealed bearing is set between the middle of the rotating shaft 15 and the housing 1 as a medium. A bevel gear 20 is fixed at the right end. The bevel gear 20 is placed vertically and meshes with the bevel gear 21 below. The two bevel gears are surrounded by a sealing box 17. In order to prevent liquid from corroding the bevel gears during use, the sealing box 17 is fixed with a crossbar 16, which also helps to stabilize the operation of the cleaning device. The bevel gear 21 is placed horizontally and transmits power to the vertical bar 18 below through the transmission of the bevel gear 20. The rotation of the vertical bar 18 drives the cleaning rope 19 to rotate. The cleaning rope 19 gradually changes from an arc shape to a near horizontal shape due to centrifugal force when it is stationary to rotating, and then cleans the blockage inside the housing 1. The cleaning rope 19 at the bottom is used to clean the clumps or blockages in the low flow port, which is more prone to clumps.

[0034] When the equipment is running, the feed pipe 5 delivers raw materials into the filter assembly. The material passes through the filter block 26, which intercepts larger particles. The inclined surface of the filter block 26 is connected to the inflow pipe 4. Even if large particles are intercepted, they are difficult to clog between the filter gaps. After being flushed by the water flow, they will fall down the inclined surface to the L-shaped pipe 6. The L-shaped pipe 6 is a collection device. The intercepted larger particles will be pushed to the vicinity of the material block 7 by the reaction force of the water flow. Finally, the staff can unscrew the material block 7 to remove the waste material. The four fixing blocks 22 are fixed on the inflow pipe 4 and the feed pipe 5. By removing the locking pin 25 in the fixing block 22 and then pulling out the limiting pin 23, the lifting block 24 can be lifted upwards. The lifting block 24 is a fixed limiting device and is also convenient to pick up. It is an integral part of the filter block 26, thus completing the disassembly of the entire filter device.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
