Description

Technical Field

[0001] This utility model belongs to the technical field of mineral processing equipment, specifically relating to a mud and sand separation device for iron ore crushing and washing. Background Technology

[0002] Iron ore refers to a mineral aggregate from which iron or iron compounds can be extracted under existing technological and economic conditions, and which has economic value for development and utilization.

[0003] When processing iron ore, operators crush it to produce particles of a specific size. Hydrocyclones are then used to wash and separate the crushed ore. The crushed ore is mixed with water to form a slurry, which is then fed into the hydrocyclone. This process separates the iron ore from the sediment, improving the ore's purity. Therefore, a hydrocyclone is a sediment separation device used for iron ore crushing and washing. However, during operation, the slurry typically enters the hydrocyclone at a certain pressure and speed. This causes strong scouring and friction against the inner wall of the feed pipe. Over time, the feed pipe wears down. If not replaced, this can affect the hydrocyclone's performance. Since the feed pipe is usually welded directly to the hydrocyclone's body, it's inconvenient for operators to maintain and replace it, thus complicating the hydrocyclone's maintenance.

[0004] Therefore, this utility model provides a mud and sand separation device for iron ore crushing and washing to solve the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figures 1-4 This utility model provides the following technical solution: a mud and sand separation device for iron ore crushing and washing, including a hydrocyclone body 1, an overflow port 2 on the top surface of the hydrocyclone body 1, and a bottom flow port 3 on the top surface of the hydrocyclone body 1. A through groove 4 is opened on one side surface at the top of the hydrocyclone body 1. A fixed pipe 5 is fixedly connected to one side surface of the hydrocyclone body 1 outside the through groove 4. One end of a connecting pipe 6 is inserted into the fixed pipe 5. The other end of the connecting pipe 6 extends into the through groove 4. A feed pipe 9 is fixedly connected to one side surface of the connecting pipe 6. A connecting block 10 is symmetrically connected to the outer surface of one end of the feed pipe 9. One end of the connecting block 10 extends into the connecting groove 11. The connecting groove 11 is opened on the side surface of the fixing block 12 facing the feed pipe 9. The fixing block 12 is symmetrically connected to the outer surface of one end of the fixing pipe 5. A limiting groove 13 is opened on the top surface of the connecting block 10. One end of the limiting insert 14 is slidably inserted into the limiting groove 13. The other end of the limiting insert 14 passes through the fixing block 12 and is connected to the connecting plate 15. A support frame 21 is connected to the outer surface of the bottom end of the hydrocyclone body 1.

[0023] Preferably, a sealing ring 7 is connected around the outer surface of one end of the connecting pipe 6, and one end of the sealing ring 7 is engaged in the sealing groove 8 opened on the inner surface of the fixing pipe 5.

[0024] In actual use, when the connecting tube 6 is slidably inserted into the fixed tube 5, the sealing ring 7 on the connecting tube 6 will move to the sealing groove 8 opened on the inner side of the fixed tube 5, so that the sealing ring 7 can be elastically locked in the sealing groove 8, thereby increasing the sealing between the connecting tube 6 and the fixed tube 5 and preventing leakage at the fixed tube 5. The sealing ring 7 is made of rubber.

[0025] Preferably, a support frame 16 is connected to one end of the fixing block 12 away from the fixing tube 5. A screw 17 is threaded through the middle of the top surface of the support frame 16. The other end of the screw 17 is connected to the inner surface of the bearing 18. The bearing 18 is embedded in the top surface of the connecting plate 15. Limiting blocks 14 are connected to the bottom surfaces at both ends of the connecting plate 15.

[0026] In practical use, by turning the screw 17, the screw 17 can rotate in the bearing 18, which can change the position of the screw 17 on the stand 16, so that the screw 17 can drive the connecting plate 15 to move inside the stand 16. In this way, the connecting plate 15 will move with the limiting block 14.

[0027] Preferably, both ends of the connecting plate 15 are connected to sliders 19, one end of the slider 19 extends into the slide groove 20, the slide groove 20 is opened on the inner surface of the top of the stand 16, and the slider 19 is slidably connected to the stand 16 through the slide groove 20.

[0028] In practical use, when the connecting plate 15 moves, the sliders 19 at both ends of the connecting plate 15 will also slide in the grooves 20 on the upright 16, thereby ensuring the movement trajectory of the connecting plate 15, so that when the connecting plate 15 moves, it can accurately insert the limiting plug 14 into the limiting groove 13 on the connecting block 10.

[0029] Preferably, the bottom surface of the support frame 21 is provided with a movable groove 22, the top surface of the inner side of the movable groove 22 is connected to an electric push rod 23, the movable end of the electric push rod 23 is connected to the top surface of the mounting block 24, the bottom surface of the mounting block 24 is connected to a pulley 25, and the mounting block 24 is slidably connected to the support frame 21 through the movable groove 22.

[0030] In practical use, the electric push rod 23 is electrically connected to an external power source via a control switch. This allows the operator to control the electric push rod 23 via the switch. By activating the electric push rod 23, the movable end of the electric push rod 23 can move the mounting block 24 in the movable groove 22, allowing the pulley 25 at the bottom of the mounting block 24 to move out of or retract into the movable groove 22.

[0031] Preferably, an inspection port 26 is provided on one side of the support frame 21 at one side of the electric push rod 23. The position of the inspection port 26 is connected to the position of the movable groove 22, and a door panel 27 is fixedly connected to one side of the support frame 21 outside the inspection port 26 by bolts.

[0032] In practical use, the door panel 27 is fixed to the support frame 21 with bolts, so that the door panel 27 can cover and protect the inspection port 26. The door panel 27 can be removed by unscrewing the bolts, so that the operator can maintain the electric push rod 23 in the movable groove 22.

[0033] Working principle: When using this iron ore crushing and washing mud and sand separation device, by activating the electric push rod 23, the movable end of the electric push rod 23 drives the mounting block 24 to move in the movable groove 22. At this time, the pulley 25 at the bottom of the mounting block 24 can move out of the movable groove 22, so that the pulley 25 contacts the ground and supports the hydrocyclone body 1. At this time, the operator can use the pulley 25 to move the hydrocyclone body 1 to the designated position to prevent manual handling. After the hydrocyclone body 1 has moved to the designated position, the electric push rod 23 is activated again, so that the movable end of the electric push rod 23 drives the pulley 25 at the bottom of the mounting block 24 to retract into the movable groove 22. At this time, the support frame 21 will contact the ground again and support the hydrocyclone body 1, ensuring the hydrocyclone... To ensure the stability of the hydrocyclone body 1 during use, the overflow port 2, underflow port 3, and feed pipe 9 on the hydrocyclone body 1 are connected to their respective pipes. The slurry formed by the crushed iron ore and water can then be transported through the feed pipe 9 into the hydrocyclone body 1 for cleaning and separation. The slurry entering the hydrocyclone body 1 undergoes three-dimensional elliptical shear turbulence. Due to the different densities of the iron ore particles and the sediment, the centrifugal force, centripetal buoyancy, and fluid drag also differ. Under centrifugal settling, the denser iron ore particles are discharged from the underflow port 3, while the less dense sediment is discharged from the overflow port 2 with the secondary upward vortex, thus achieving the separation of iron ore and sediment. The feed pipe 9 then... During feeding, the slurry will strongly scour and rub against the inner wall of the feed pipe 9. After long-term operation, the feed pipe 9 will wear out, requiring replacement. Simply turn the screw 17, allowing it to rotate within the bearing 18. This will change the position of the screw 17 on the support frame 16, causing it to move the connecting plate 15 upwards inside the support frame 16. This will cause the connecting plate 15, along with one end of the limiting block 14, to separate from the limiting groove 13. Pulling the feed pipe 9 will then separate it from the connecting groove 11, along with the connecting block 10. Simultaneously, the connecting pipe 6 at one end of the feed pipe 9 will also separate from the fixing pipe 5. This allows the feed pipe 9 to be disassembled, enabling operators to control the feeding process. After the old feed pipe 9 is removed, the connecting pipe 6 of the new feed pipe 9 is inserted into the fixed pipe 5, with one end of the connecting pipe 6 extending into the through groove 4. The sealing ring 7 on the connecting pipe 6 will also move and engage with the sealing groove 8, thereby increasing the sealing between the connecting pipe 6 and the fixed pipe 5. At this time, the connecting block 10 on the feed pipe 9 will also be inserted into the connecting groove 11. Then, the screw 17 is turned again, causing the screw 17 to move the limiting insert 14 at the bottom of the connecting plate 15 downwards, so that one end of the limiting insert 14 is inserted into the limiting groove 13 on the connecting block 10, thereby fixing the position of the connecting block 10 in the fixed block 12, and installing the feed pipe 9 in the fixed pipe 5. At this time, the installation operation of the feed pipe 9 is completed.This design allows operators to disassemble and assemble the feed pipe 9 without tools, thus facilitating the maintenance of the feed pipe 9 in the mud and sand separation device.
