Description

Technical Field

[0001] This utility model relates to the field of magnetic mineral processing technology, and in particular to a split-type magnetic microfluidic mineral processing machine. Background Technology

[0002] Currently, the equipment used in magnetite beneficiation plants generally includes magnetic separators, desliming tanks, magnetic separation columns, and washing machines. Magnetic separators are permanent magnet products, working by using magnetic force to attract magnetic materials. However, the concentrate separated by magnetic separators often contains magnetic inclusions, affecting the concentrate grade. Desliming tanks are also permanent magnet products, working by utilizing the combined effects of material gravity, rising water buoyancy, and magnetic field force for separation. However, because the magnetic field of permanent magnet products is a single, fixed permanent magnet, the separation efficiency is low, and fluctuations in the input material significantly affect the separation effect. Magnetic separation columns and washing machines are both electromagnetic products. Their working principle is as follows: the separation cylinder is filled with backwash water flowing upwards. The slurry is fed into the upper part of the separation cylinder, and the concentrate particles agglomerate and sink under the influence of the magnetic field. The tailings overflow and are flushed out from the top of the separation cylinder. This type of equipment can effectively refine the concentrate, improve the concentrate grade, and the adjustable magnetic field helps to improve the separation efficiency. However, current magnetic separation columns and washing machines are all integrated designs. As the equipment size gradually increases, the difficulty of transporting and installing the equipment increases. Utility Model Content

[0020] The purpose of this invention is to provide a split-type magnetic microfluidic sorting machine to solve the problems existing in the prior art, facilitate split transportation and installation, reduce the difficulty of maintenance, and improve the sorting effect.

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-10As shown, this utility model provides a split-type magnetic microfluidic slurry cleaner 100, including a feed trough assembly 1, an overflow trough assembly 2, and a magnetic system assembly 3. The feed trough assembly 1 includes a guide cylinder 102 and multiple guide plates 103 fixedly connected to the guide cylinder 102. The overflow trough assembly 2 is provided with a filter device 5. Specifically, the overflow trough assembly 2 is provided with a liquid inlet channel 201, and the filter device 5 is fixedly connected inside the liquid inlet channel 201. The lower end of the guide cylinder 102 is detachably fixedly connected to the side of the filter device 5 near the guide cylinder 102. The outer wall of the guide cylinder 102 can guide the slurry entering from the feed port 101 of the feed trough assembly 1 to the liquid inlet channel 201. The magnetic system assembly 3 is detachably fixedly connected to the overflow trough assembly 2.

[0023] The feed inlet 101 receives slurry from an external feed pipe. The slurry is guided by the guide tube 102, and the guide plate 103 improves the uniformity of circumferential liquid intake. After entering the inlet channel 201, the filter device 5 performs coarse filtration, removing large particles of impurities. The slurry then enters the working chamber 1001 for magnetic separation. The feed trough assembly 1, overflow trough assembly 2, and magnetic system assembly 3 of this invention are designed as separate units, facilitating separate transportation and installation. Furthermore, after removing the feed trough assembly 1, the top of the overflow trough assembly 2 is open, allowing easy access to the equipment from the top for internal inspection, reducing maintenance difficulty.

[0024] In this specific embodiment, all guide plates 103 extend from the upper end of the guide cylinder 102 to the lower end of the guide cylinder 102. All guide plates 103 are radially fixedly connected to the outer side wall of the guide cylinder 102. A guide channel 104 is formed between two adjacent guide plates 103, which is beneficial to improve the uniformity of circumferential liquid inlet in the liquid inlet channel 201.

[0025] In this specific embodiment, it also includes multiple pressure plates 6 and multiple connectors 8, preferably studs; the liquid inlet channel 201 is annular, and both the guide tube 102 and the filter device 5 are conical. Preferably, the taper of the filter device 5 is the same as the taper of the guide tube 102; the inner wall of the large end of the guide tube 102 contacts the outer wall of the small end of the filter device 5, one end of each pressure plate 6 contacts the outer wall of the large end of the guide tube 102, and the other end of each pressure plate 6 is disposed outside the small end of the filter device 5; each connector 8 is used to fix and connect the pressure plate 6 and the filter device 5, and to clamp the guide tube 102 between the pressure plate 6 and the filter device 5. When installing the ore feeder assembly 1, the guide tube 102 is placed on the filter device 5, and the connectors 8 (such as studs) pass through the pressure plate 6 and the filter device 5 to press the guide tube 102 onto the filter device 5 and fix it, thereby realizing the installation of the ore feeder assembly 1.

[0026] In this specific embodiment, it also includes a cone assembly 7 and a water supply assembly 4. The water supply assembly 4 includes a water supply pipe 404. The large end of the cone assembly 7 is connected to the end of the magnetic system assembly 3 away from the feed trough assembly 1. The feed trough assembly 1, overflow trough assembly 2, magnetic system assembly 3 and cone assembly 7 are connected in sequence to form a working cavity 1001. The water supply pipe 404 is fixedly connected to the cone assembly 7. The inlet of the water supply pipe 404 is located outside the cone assembly 7. After the cone assembly 7 is connected to the magnetic system assembly 3, the outlet of the water supply pipe 404 extends into the working cavity 1001. The water supply pipe 404 is used to provide backwash water flowing from bottom to top into the working cavity 1001.

[0027] In this specific embodiment, the water supply assembly 4 further includes an annular baffle 401, a water supply cylinder 402, and a transition pipe 403. The water supply cylinder 402 is disposed inside the working chamber 1001. The lower end of the transition pipe 403 is fixedly connected to the bottom wall opening of the water supply cylinder 402, and the upper end of the transition pipe 403 extends upward. After the cone assembly 7 is connected to the magnetic system assembly 3, the outlet end of the water supply pipe 404 extends into the transition pipe 403 and is clearance-fitted with the transition pipe 403. The annular baffle 401 is sleeved outside the outlet end of the water supply pipe 404 and is fixedly connected to the water supply pipe 404. After the cone assembly 7 is connected to the magnetic system assembly 3, the annular baffle 401 is located below the bottom wall opening and forms a water passage 405 between it and the bottom wall of the water supply cylinder 402. The transition pipe 403 is used to supply water into the water supply cylinder 402, and the water supply cylinder 402 is used to supply water to the sorting area inside the equipment. The annular baffle 401 at the bottom of the water supply cylinder 402 can completely block the opening of the bottom wall of the water supply cylinder 402, so a certain gap can be left between the water supply pipe 404 and the transition pipe 403. This increases the assembly gap between the water supply pipe 404 and the transition pipe 403, making it easier for the water supply pipe 404 to be inserted into the transition pipe 403, reducing the installation accuracy requirements, simplifying the difficulty of matching the water supply pipe 404 and the transition pipe 403, and simplifying the installation difficulty of the cone assembly 7 and the water supply pipe 404. The liquid leaking from the gap between the water supply pipe 404 and the transition pipe 403 flows downward to the annular baffle 401. Under the interception of the annular baffle 401, it cannot flow downward, but flows out along the water passage 405 and then into the sorting area inside the equipment, ensuring that the backwashing effect can still be guaranteed even if there is water leakage at the lower end of the transition pipe 403. Furthermore, the water supply pipe 404 is not welded or sealed to the transition pipe 403, which reduces the processing requirements for the water supply pipe 404 and the transition pipe 403.

[0028] In this specific embodiment, the large end of the cone assembly 7 is detachably and fixedly connected to the lower end of the magnetic system assembly 3.

[0029] It should be noted that the cone assembly 7 and the magnetic system assembly 3 can be designed as an integral structure or a separate structure as needed.

[0030] In this specific embodiment, the water supply pipe 404 includes a first pipe body 406 and a second pipe body 407. The inlet end of the first pipe body 406 and the inlet end of the second pipe body 407 are both located outside the cone assembly 7. The outlet end of the first pipe body 406 extends into the transition pipe 403. The annular baffle 401 is sleeved on the outlet end of the first pipe body 406 and fixedly connected to the first pipe body 406. The second pipe body 407 is connected to and communicates with the first pipe body 406.

[0031] In this specific embodiment, the inner diameters of pipe body one 406 and pipe body two 407 are different. Preferably, the inner diameter of pipe body one 406 is larger than that of pipe body two 407. The water supply pipe 404 is formed by the convergence of pipe body one 406 and pipe body two 407. The water flow of both pipes can be controlled by valves. Since pipe body one 406 and pipe body two 407 have different diameters, the larger pipe can be used for coarse adjustment of water flow, and the smaller pipe can be used for fine adjustment of water flow. Thus, the water flow can be adjusted by both pipes together, improving the control accuracy of the water flow rate.

[0032] In this specific embodiment, the magnetic system assembly 3 includes a housing 301 with openings at both ends and a coil 304 disposed inside the housing 301. A magnetic system upper flange 302 is fixedly connected to the upper opening of the housing 301. The magnetic system upper flange 302 is detachably fixedly connected to the overflow groove flange 208 on the overflow groove assembly 2. A sealing ring 9 is provided between the magnetic system upper flange 302 and the overflow groove flange 208.

[0033] In this specific embodiment, a second connector 10 is also included. A magnetic flange 305 is fixedly connected to the lower end of the outer shell 301. A lower magnetic flange 303 is provided at the lower opening of the outer shell 301. A groove 306 is provided on the bottom surface of the lower magnetic flange 303. The second connector 10 can sink into the groove 306 and fix the lower magnetic flange 303 and the magnetic flange 305. The lower magnetic flange 303 is detachably fixedly connected to the upper conical flange 209 on the conical assembly 7. Sealing rings 9 are provided between the lower magnetic flange 303 and the magnetic flange 305, and between the lower magnetic flange 303 and the upper conical flange 209.

[0034] In this specific embodiment, the overflow trough flange 208 and the magnetic system upper flange 302 are fixed with bolts to assemble the overflow trough assembly 2 and the magnetic system assembly 3; the sealing ring 9 between the overflow trough flange 208 and the magnetic system upper flange 302 is used to achieve sealing between the flanges.

[0035] In this specific embodiment, the lower magnetic flange 303 and the magnetic flange 305 below the magnetic system assembly 3 are fastened together by bolts. The bolt heads are recessed into the groove 306 of the lower magnetic flange 303. By disassembling the lower magnetic flange 303, the magnetic coil 304 inside the housing can be removed for maintenance. The lower magnetic flange 303 can be used for the installation of the magnetic system assembly 3 and can also seal the coil 304 inside the magnetic system assembly 3 to prevent slurry from entering and damaging the coil 304.

[0036] In this specific embodiment, when the magnetic system assembly 3 and the cone assembly 7 are separate structures, a cone upper flange 209 is provided at the upper end of the cone assembly 7. The magnetic system lower flange 303 below the magnetic system assembly 3 is fastened to the cone upper flange 209 of the cone assembly 7 by bolts, thereby realizing the assembly between the magnetic system assembly 3 and the cone assembly 7. The sealing rings 9 between the magnetic system lower flange 303 and the magnetic system flange 305, and between the magnetic system lower flange 303 and the cone upper flange 209, are used to achieve sealing between the flanges.

[0037] In this specific embodiment, the overflow tank assembly 2 includes an outer cylinder wall 203, an inner cylinder wall 204, and an overflow discharge cylinder 205. The inner cylinder wall 204 is sleeved inside the outer cylinder wall 203 and forms an inlet channel 201 between them. The outer shell 301 is detachably and fixedly connected to the lower end of the outer cylinder wall 203 and is sealed. The overflow discharge cylinder 205 is sleeved outside the outer cylinder wall 203 and fixedly connected to it, allowing overflow discharge. The upper and lower ends of the cylinder 205 are sealed to the outer cylinder wall 203. The inner wall of the overflow discharge cylinder 205 and the outer surface of the outer cylinder wall 203 form a liquid collection cavity 206. The overflow discharge cylinder 205 is provided with a discharge port 202. At least two flow pipes 207 are provided between the outer cylinder wall 203 and the inner cylinder wall 204. Preferably, there are multiple flow pipes 207, such as eight, which are evenly distributed circumferentially between the outer cylinder wall 203 and the inner cylinder wall 204.

[0038] Tailings within the inner cylinder wall 204 can enter the collection chamber 206 through the flow pipe 207 under the action of backflushing water and be discharged through the outlet 202. Specifically, after the slurry enters the working chamber 1001 through the inlet channel 201, the magnetic particles in the slurry agglomerate under the action of the magnetic field. Unagglomerated tailings particles flow into the inner cavity of the inner cylinder wall 204 under the action of backflushing water, converge into the collection chamber 206 through the flow pipe 207, and are finally discharged through the outlet 202. This utility model forms a sorting structure of "feeding from all sides and overflowing from the center". Since the magnetic system component 3 is located outside the outer cylinder wall 203, the "feeding from all sides and overflowing from the center" sorting structure allows the slurry to be closer to the magnetic system component 3, improving the sorting effect.

[0039] In this specific embodiment, the axis of the annular baffle 401 is perpendicular to that of the outer cylinder wall 203.

[0040] In this specific embodiment, a plurality of water outlets 408 are provided on the side wall of the water supply cylinder 402. The water flow outlet direction of the water passage 405 between the water supply pipe 404 and the transition pipe 403 is the same as the direction of the water outlets 408 of the water supply cylinder 402.

[0041] In this specific embodiment, the feed trough assembly 1 further includes a buffer cylinder 105. The inlet of the buffer cylinder 105 is located directly below the feed port 101. A guide cylinder 102 is sleeved on the outside of the buffer cylinder 105, and the upper end of the guide cylinder 102 is fixedly connected to the upper end of the buffer cylinder 105. The slurry entering through the feed port 101 can flow into the buffer cylinder 105. The slurry overflows to the surroundings through the buffer cylinder 105 and is guided by the guide cylinder 102 to the liquid inlet channel 201. It then enters the liquid inlet channel 201 through the guide assembly.

[0042] In this specific embodiment, the axis of the water outlet section of the pipe body 406 is parallel or collinear with the axis of the outer cylinder wall 203.

[0043] In this specific embodiment, the outlet section of pipe body two 407 is inclined upward, and water is injected into the outlet section of pipe body one 406 through the inclined pipe.
