A high-efficiency filtration device for hydrocyclones

Abstract

This utility model relates to the technical field of coarse ore slurry filtration devices, and discloses a high-efficiency filtration device for hydrocyclones, including a filter barrel. A fixed column is fixedly connected to the lower side of the inner surface of the filter barrel, and a hollow box is fixedly connected to the top of the fixed column. A fixed disk is fixedly connected to the upper surface of the hollow box. This utility model, by setting up a fixed filter rod, a driven gear block, a movable disk, a driving gear, and a movable filter rod, allows the shaft and driving gear to rotate when the first motor starts. The rotation of the driving gear drives the driven gear block, causing the driven gear block and the movable disk to rotate as a whole. During this process, the maximum gap between the fixed filter rod and the movable filter rod gradually widens, allowing crushed ore that could not originally pass through the fixed and movable filter rods to flow out with the coarse ore slurry beyond them. This achieves the function of adjusting the overall screening range of the filter barrel.

Description

Technical Field

[0001] This utility model relates to the technical field of coarse slurry filtration devices, and more specifically, to a high-efficiency filtration device for a hydrocyclone. Background Technology

[0002] A hydrocyclone is a high-efficiency classifying device that uses centrifugal force to achieve solid-liquid or solid-gas separation. It consists of a cylindrical body, a conical separation section, and a feed inlet. During operation, the mixed medium enters tangentially to form a high-speed rotating flow field. Heavy phase particles settle towards the wall under centrifugal force and are discharged from the underflow outlet, while the light phase medium is discharged through the overflow pipe. It has advantages such as simple structure, no moving parts, and large processing capacity. It is widely used in mining, mineral processing, wastewater treatment, and petrochemical industries. The separation accuracy can be optimized by adjusting the feed pressure and cone angle.

[0003] Before using a hydrocyclone to classify coarse ore slurry, operators need to use a high-efficiency filter to quickly filter out any large pieces of broken ore that may be present in the slurry, so as to prevent the broken ore from damaging the inside of the hydrocyclone. However, in actual use, although existing high-efficiency filters have basic high-efficiency filtration functions, the spacing between the screening columns inside the existing high-efficiency filters is generally fixed, so operators cannot adjust the screening range of the high-efficiency filters. Therefore, improvements are needed. Utility Model Content

[0011] As a preferred technical solution of this utility model, a limiting rod located below the double-threaded rod is fixedly connected to the rear surface of the fixing plate. The front end of the limiting rod passes through the fixing plate and the moving block in sequence and extends to the rear surface of the motor protective sleeve and is fixedly connected to the motor protective sleeve.

At this time, the rotation of the driving gear will drive the driven gear block, thereby causing the driven gear block and the movable disc to start rotating as a whole. During this process, the maximum gap between the fixed filter rod and the movable filter rod will gradually increase, allowing crushed ore that could not originally pass through the fixed filter rod and the movable filter rod to flow out with the coarse ore slurry outside the fixed filter rod and the movable filter rod, thereby realizing the function of adjusting the overall screening range of the filter barrel.

The movement of the moving blocks drives the first connecting rod, causing the first, second, and third connecting rods to rotate. At the same time, the other end of the third connecting rod will adjust the hinge plate, thereby causing the hinge plate, telescopic rod, and cone plate to move upward. At this time, the large pieces of ore located above the cone plate will move upward along with the cone plate, thus facilitating the operator to clean up these large pieces of ore.

[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] like Figures 1 to 6 As shown, this utility model provides a high-efficiency filtration device for a hydrocyclone, including a filter barrel 1. A fixed column 2 is fixedly connected to the lower side of the inner surface of the filter barrel 1. A hollow box 3 is fixedly connected to the top of the fixed column 2. A fixed disk 4 is fixedly connected to the upper surface of the hollow box 3. A driven gear block 5 is movably connected to the middle of the lower surface of the fixed disk 4. The top of the driven gear block 5 passes through the fixed disk 4 and extends to the top of the fixed disk 4 and is fixedly connected to a movable disk 6. The lower surface of the movable disk 6 is movably connected to the upper surface of the fixed disk 4. A fixed filter rod 7 is fixedly connected to the outer side of the upper surface of the fixed disk 4. A movable filter rod 30 is fixedly connected to the outer side of the upper surface of the movable disk 6. A first motor 8 is fixedly installed on the inner surface of the hollow box 3. A round shaft 9 is fixedly sleeved at the other end of the output shaft of the first motor 8. A driving gear 10 is fixedly sleeved at the other end of the round shaft 9. The outer surface of the driving gear 10 and the outer surface of the driven gear block 5 are meshed together.

[0027] When the operator starts motor 8, the circular shaft 9 and the drive gear 10 will start to rotate. Since the outer surface of the drive gear 10 and the outer surface of the driven gear block 5 mesh with each other, the rotation of the drive gear 10 will drive the driven gear block 5, thereby causing the driven gear block 5 and the movable disk 6 to start rotating as a whole.

[0028] The fixed filter rod 7 is fixedly connected to the top end of a fixed ring 11, the lower surface of the fixed ring 11 is fixedly connected to the upper surface of the filter barrel 1, and the movable filter rod 30 is fixedly connected to the top end of a movable ring 12, the outer surface of the movable ring 12 is movably connected to the inner surface of the fixed ring 11.

[0029] The design of the fixed ring 11 and the movable ring 12 allows the movable ring 12 to rotate together with the movable filter rod 30.

[0030] The filter barrel 1 is fixedly connected to the lower surface of the hydrocyclone feed pipe 28. The upper surface of the movable disc 6 is movably connected to the middle of the cone plate 13. The lower surface of the cone plate 13 is fixedly connected to the telescopic rod 14. The bottom end of the telescopic rod 14 passes through the fixed disc 4, the hollow box 3 and the filter barrel 1 in sequence and extends to the bottom of the filter barrel 1 and is fixedly connected to the hinge plate 15. The inner surface of the hinge plate 15 and the outer surface of the hydrocyclone feed pipe 28 are movably connected. The outer surface of the telescopic rod 14 is movably sleeved with the inner surfaces of the fixed disc 4, the hollow box 3 and the filter barrel 1 respectively.

[0031] The length design of the telescopic rod 14 allows the cone plate 13 to move upward and eventually move above the movable ring 12.

[0032] The movable plate 6 has movable grooves 29 on both the front and rear sides of its upper surface, and the inner surface of the movable grooves 29 is movably connected to the outer surface of the telescopic rod 14.

[0033] The design of the movable slot 29 ensures that the telescopic rod 14 does not affect the overall rotation of the driven gear block 5 and the movable disk 6.

[0034] The filter barrel 1 has a sleeve plate 16 fixedly connected to its outer surface, a motor protective sleeve 18 fixedly connected to its outer surface, a second motor 19 fixedly installed on the inner surface of the motor protective sleeve 18, and a fixing plate 17 located behind the motor protective sleeve 18 fixedly connected to both the front and rear sides of the left surface of the sleeve plate 16.

[0035] The design of the motor protective sleeve 18 serves to protect the second motor 19.

[0036] Among them, the other end of the output shaft of the second motor 19 is fixedly sleeved with a double-threaded rod 20. The rear end of the double-threaded rod 20 passes through the motor protective sleeve 18 and the fixing plate 17 in sequence and extends to the rear surface of the fixing plate 17. The outer surface of the double-threaded rod 20 is threaded with a moving block 21.

[0037] When motor 19 is running, the double-threaded rod 20 will start to rotate, and the moving block 21 will move under the drive of the double-threaded rod 20.

[0038] The rear surface of the fixed plate 17 is fixedly connected to a limiting rod 22 located below the double-threaded rod 20. The front end of the limiting rod 22 passes through the fixed plate 17 and the moving block 21 in sequence and extends to the rear surface of the motor protective sleeve 18 and is fixedly connected to the motor protective sleeve 18. The outer surface of the limiting rod 22 and the inner surface of the moving block 21 are movably sleeved.

[0039] The design of the limit rod 22 serves to ensure that the two moving blocks 21 remain stable during movement.

[0040] There are two movable blocks 21. The left surface of each movable block 21 is hinged to a first connecting rod 23, and the bottom end of the first connecting rod 23 is hinged to a second connecting rod 24.

[0041] When the moving block 21 moves, the first link 23 will rotate along with the moving block 21. At the same time, the other end of the first link 23 will drive the second link 24, thereby causing the second link 24 to also start to rotate.

[0042] Among them, the other end of the second connecting rod 24 is hinged to the third connecting rod 25, and the other end of the third connecting rod 25 is hinged to the left surface of the hinge plate 15.

[0043] When link 24 rotates, the other end of link 24 will drive link 3 25, thereby causing link 3 25 to start rotating as well.

[0044] The upper surface of the sleeve plate 16 is fixedly connected to a protective plate 26, and the lower surface of the sleeve plate 16 is fixedly connected to support legs 27 located on the front and rear sides of the hinge plate 15.

[0045] The design of the protective plate 26 serves to protect the double-threaded rod 20.

[0046] Working principle and usage process of this utility model:

[0047] First, the operator starts motor 8. As motor 8 runs, the circular shaft 9 and the drive gear 10 will start to rotate. Since the drive gear 10 meshes with the driven gear block 5, the driven gear block 5 and the movable disk 6 will rotate under the meshing of the drive gear 10. As the movable disk 6 rotates, the maximum gap between the fixed filter rod 7 and the movable filter rod 30 will change until the gap between the fixed filter rod 7 and the movable filter rod 30 meets the operator's filtration needs.

[0048] The operator then pours the coarse slurry into the filter tank 1. The slurry passes through the fixed filter rod 7 and the movable filter rod 30, flows out from the bottom of the hydrocyclone feed pipe 28, and enters the hydrocyclone. Large pieces of ore in the slurry are caught by the fixed filter rod 7 and the movable filter rod 30. When a large amount of large pieces of ore accumulates above the cone plate 13, the operator starts the second motor 19. As the second motor 19 runs, the double-threaded rod 20 begins to rotate. At this time, the moving block 21 moves under the drive of the double-threaded rod 20. Simultaneously, the first connecting rod 23, the second connecting rod 24, and the third connecting rod 25 all begin to rotate with the movement of the moving block 21. The other end of the third connecting rod 25 drives the hinge plate 15 during rotation, causing the hinge plate 15, the telescopic rod 14, the cone plate 13, and the large pieces of ore to move upward, thus facilitating the operator to remove the large pieces of ore from inside the filter tank 1.
