Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, and in particular to a flow regulating mechanism for the discharge port of a magnetic separator. Background Technology

[0002] Magnetic separators are mineral processing machines that separate minerals or mineral aggregates based on their magnetic differences in a magnetic field. After the slurry flows into the tank through the feed box, the mineral particles enter the feed area of ​​the tank in a loose state under the action of the water flow from the feed water pipe. Under the action of the magnetic field, the magnetic mineral particles undergo magnetic aggregation to form "magnetic clusters" or "magnetic chains". They move towards the magnetic poles in the slurry under the action of magnetic force and are adsorbed onto the cylinder. Since the polarity of the magnetic poles is alternately arranged and fixed along the rotation direction of the cylinder, the "magnetic clusters" or "magnetic chains" will generate a magnetic stirring phenomenon as the cylinder rotates. Non-magnetic minerals such as gangue are dislodged during the agitation. The "magnetic clusters" or "magnetic chains" that are finally adsorbed on the surface of the cylinder are the concentrate. The concentrate is discharged into the concentrate tank under the action of the flushing water flow from the discharge water pipe as the edge of the magnetic system where the magnetic force is weakest. Non-magnetic or weakly magnetic minerals are left in the slurry and discharged out of the tank with the slurry, becoming tailings.

[0003] Traditional magnetic separators mostly use various valves to control the discharge flow rate. However, after a long period of use, the valves may be damaged by friction from the ore, thus reducing the practicality of the flow rate control mechanism. In addition, traditional flow rate control mechanisms generally have poor sealing performance. Therefore, a new flow rate control mechanism for the discharge port of a magnetic separator is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to at least solve one of the technical problems existing in the prior art, and to provide a flow regulation mechanism for the discharge port of a magnetic separator. This can solve the problem that the traditional flow regulation mechanism for the discharge port of a magnetic separator mostly adopts various valves to control the discharge flow. However, after a long period of use, the valves may be damaged by friction from the ore, thus reducing the practicality of the flow regulation mechanism.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a flow regulating mechanism for the discharge port of a magnetic separator, comprising a screening box, a selection box fixedly connected to one side of the screening box, a support frame fixedly connected to the screening box, a drive assembly provided on the support frame, and a magnetic separation roller rotatably connected inside the screening box.

[0006] The magnetic separator roller rotates via a drive assembly;

[0007] Both the screening box and the selection box are fixedly connected to the bottom of the discharge pipe, and both discharge pipes are fixedly connected to the mounting plate, which is equipped with an adjustment mechanism.

[0008] Preferably, the adjustment mechanism includes a motor, which is fixedly mounted on the mounting plate, and an adjustment disc is fixedly connected to the output end of the motor;

[0009] The regulating plate has through holes, which are stepped and arranged in a ring array on the regulating plate.

[0010] The inside of the through hole is equipped with a funnel-shaped flow guide tube;

[0011] An installation hole is provided on the inner wall of the through hole. A spring is fixedly connected inside the installation hole. A slide rod is fixedly connected to the guide tube. The slide rod is slidably connected inside the installation hole and fixedly connected to the spring.

[0012] Preferably, the diameter of the opening of the guide tube is set to increase sequentially.

[0013] Preferably, a water pipe is fixedly connected to the inner wall of the selection box, and a nozzle is provided on the water pipe;

[0014] The water pipes are connected to the external water supply equipment.

[0015] Preferably, a rubber pad is fixedly connected to the surface of the adjustment disc.

[0016] Preferably, one of the flow guides is configured as a frustum and is sealed.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] The magnetic separator uses a flow regulation mechanism at the discharge port. When it is necessary to adjust the outflow speed of the ore, simply start the motor. The motor's output drives the regulating disc to rotate, causing the guide pipe on the regulating disc to engage with the inside of the discharge pipe. This opens the discharge pipe, allowing the ore to flow out. By using guide pipes with different opening diameters, guide pipes of different diameters can be connected to the discharge pipe as needed to regulate the flow rate. Therefore, traditional valve control is no longer required, thus avoiding damage to the valve core caused by the ore during flow, extending service life, and reducing replacement and maintenance costs.

[0019] The magnetic separator uses a flow regulating mechanism at the discharge port. By setting the guide tube in a funnel shape, the inclined surface of the guide tube will not cause mechanical obstruction when it comes into contact with the discharge pipe. At the same time, when the guide tube comes into contact with the discharge pipe, the guide tube is forced to retract into the through hole, which compresses the spring. When the guide tube is perpendicular to the discharge pipe, the spring releases its elasticity, causing the guide tube to be locked into the discharge pipe, thus completing the seal between the two and preventing the ore from spilling out.

[0026] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0027] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, terms such as greater than, less than, and exceeding are understood to exclude the stated number, while terms such as above, below, and within are understood to include the stated number. The use of terms like "first" and "second" is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the quantity or sequence of the indicated technical features.

[0029] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0030] Please see Figure 1-4 This utility model provides a technical solution: a flow regulating mechanism for the discharge port of a magnetic separator, including a screening box 1, a selection box 5 fixedly connected to one side of the screening box 1, a support frame 2 fixedly connected to the screening box 1, a drive assembly 4 provided on the support frame 2, and a magnetic separation roller 3 rotatably connected inside the screening box 1.

[0031] The magnetic separator 3 rotates via the drive assembly 4;

[0032] Both the bottom of the screening box 1 and the selection box 5 are fixedly connected to the discharge pipe 7, and both discharge pipe 7 are fixedly connected to the mounting plate 8, which is equipped with an adjustment mechanism.

[0033] When magnetic separation of ore is required, the ore can be placed inside the screening box 1, and normal magnetic separation can be carried out according to the magnetic separation process. When the screened ore or tailings need to be discharged, the discharge pipe 7 can be opened by adjusting the mechanism. Therefore, the discharge flow of ore can be adjusted according to the demand.

[0034] Furthermore, a water pipe 6 is fixedly connected to the inner wall of the selection box 5, and a nozzle 13 is installed on the water pipe 6;

[0035] Water pipe 6 is connected to the external water supply equipment;

[0036] When the ore is adsorbed by the magnetic separation roller 3, as the magnetic separation roller 3 rotates, the ore rotates to the position of the nozzle 13. At this time, the nozzle 13 sprays water to wash the ore, so it falls from the magnetic separation roller 3 into the interior of the selection box 5.

[0037] Furthermore, the adjustment mechanism includes a motor 9, which is fixedly mounted on the mounting plate 8, and an adjustment disc 10 is fixedly connected to the output end of the motor 9;

[0038] The regulating disk 10 has through holes 14, which are stepped and arranged in a ring array on the regulating disk 10.

[0039] The through hole 14 is provided with a funnel-shaped guide tube 12;

[0040] An installation hole 15 is provided on the inner wall of the through hole 14. A spring 16 is fixedly connected inside the installation hole 15. A slide rod 17 is fixedly connected to the guide tube 12. The slide rod 17 is slidably connected inside the installation hole 15 and fixedly connected to the spring 16.

[0041] The diameter of the opening of the guide tube 12 is set to increase sequentially.

[0042] When it is necessary to adjust the outflow rate of ore, simply start the motor 9. The output of the motor 9 drives the regulating plate 10 to rotate, which causes the guide pipe 12 on the regulating plate 10 to engage with the discharge pipe 7, thus opening the discharge pipe 7 and allowing the ore to flow out. By setting different diameters at the opening of the guide pipe 12, guide pipes 12 of different diameters can be connected to the discharge pipe 7 as needed to adjust the flow rate. Therefore, there is no need to use traditional valve control, which avoids damage to the valve core caused by the ore during the flow process, thereby increasing the service life and reducing the cost of replacement and maintenance.

[0043] By setting the guide pipe 12 in a funnel shape, its inclined surface will not cause mechanical obstruction when it comes into contact with the discharge pipe 7. At the same time, when the guide pipe 12 comes into contact with the discharge pipe 7, the guide pipe 12 is forced to retract into the through hole 14, which compresses the spring 16. When the guide pipe 12 is perpendicular to the discharge pipe 7, the spring 16 releases its elasticity, causing the guide pipe 12 to be inserted into the discharge pipe 7, thus completing the seal between the two and preventing the ore from overflowing.

[0044] Furthermore, a rubber pad 11 is fixedly connected to the surface of the adjustment disc 10;

[0045] The rubber pad 11 ensures that the surface of the adjusting plate 10 fits more tightly with the discharge pipe 7, preventing ore leakage.

[0046] Meanwhile, one of the guide tubes 12 is configured as a frustum and is sealed;

[0047] By setting one of the guide pipes 12 to a sealed state, the discharge pipe 7 can be sealed through this guide pipe 12.

[0048] Working principle: When it is necessary to adjust the outflow rate of ore, simply start the motor 9. The output of the motor 9 drives the regulating plate 10 to rotate, which causes the guide pipe 12 on the regulating plate 10 to engage with the discharge pipe 7, thus opening the discharge pipe 7 and allowing the ore to flow out. By setting different diameters at the opening of the guide pipe 12, guide pipes 12 of different diameters can be connected to the discharge pipe 7 as needed to adjust the flow rate. Therefore, there is no need to use traditional valve control, thus avoiding damage to the valve core caused by the ore during the flow process, thereby increasing the service life and reducing the cost of replacement and maintenance.

[0049] By setting the guide pipe 12 in a funnel shape, its inclined surface will not cause mechanical obstruction when it comes into contact with the discharge pipe 7. At the same time, when the guide pipe 12 comes into contact with the discharge pipe 7, the guide pipe 12 is forced to retract into the through hole 14, which compresses the spring 16. When the guide pipe 12 is perpendicular to the discharge pipe 7, the spring 16 releases its elasticity, causing the guide pipe 12 to be inserted into the discharge pipe 7, thus completing the seal between the two and preventing the ore from overflowing.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
