Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, and specifically relates to a discharge flow regulating mechanism for a magnetic separator. Background Technique

[0002] Quartz sand, as an important industrial raw material, plays a key role in many fields such as the glass industry, foundry industry, ceramic industry, water treatment, and electronics industry. A quartz sand magnetic separator is a device that uses a magnetic field to separate magnetic minerals and non-magnetic minerals. Its working principle is to send quartz sand into a magnetic field. Magnetic minerals (such as iron minerals) are adsorbed onto the magnetic poles of the magnetic separator under the action of the magnetic field, while non-magnetic minerals (such as quartz sand) are not affected by the magnetic field and continue to move forward, thus achieving the separation of magnetic minerals and quartz sand.

[0003] Chinese Patent CN221097510U discloses a discharge port flow regulating mechanism for a quartz sand magnetic separator, including a main body. A placement table is arranged in the middle of the outer wall of the front end of the main body. A fixing plate is fixedly connected to the upper surface of the outer wall of the rear end of the main body. A first motor is arranged in the middle of the upper surface of the placement table. The output end of the first motor penetrates through the upper end of the main body to the inside of the main body and is fixedly connected to a rotating rod. A second motor is fixedly connected to the lower part of one side of the outer wall of the front end of the main body. In this utility model, during actual use, by starting the second motor to rotate the bidirectional threaded rod, the two threaded sleeves on both sides are driven to approach each other, and then the two baffles on both sides are also driven to approach each other along with the threaded sleeves. At the same time, by sliding the guide block on the outer wall of the guide rod, the purpose of assisting the baffle to move is achieved, so as to reduce the cross-sectional area of the outlet and control the discharge flow rate when discharging quartz sand.

[0004] However, in the above technical solution, when adjusting the cross-sectional area of the outlet, since the baffle is horizontally arranged, the material will accumulate on the baffle, thus affecting the feeding efficiency. Content of the Utility Model

[0020] As Figure 1-2 shown, in this embodiment, a magnetic separator discharge flow rate regulating mechanism includes a magnetic separator body 1. A discharge port 2 is provided at the bottom of the magnetic separator body 1. In this embodiment, the discharge port 2 is circular. A blanking mechanism is provided below the discharge port 2. The blanking mechanism includes an adjusting device 3 and a housing 4. The housing 4 is provided below the discharge port 2. Openings 5 are provided at both the top and bottom of the housing 4. The opening 5 at the top of the housing 4 encloses the discharge port 2. The adjusting device 3 is provided at the central position below the discharge port 2. The adjusting device 3 includes a telescopic mechanism 3-1. A plug is provided at the top end of the telescopic mechanism 3-1. The plug includes an adjusting portion 3-2 and a sealing portion 3-3. The adjusting portion 3-2 is provided at the top end of the sealing portion 3-3. The cross-sectional area of the adjusting portion 3-2 increases from top to bottom. The cross-section of the sealing portion 3-3 matches the contour of the opening 5 of the discharge port 2. In this embodiment, the telescopic mechanism 3-1 is an electric control telescopic rod.

[0021] In this embodiment, a plurality of support arms 3-4 are evenly distributed on the side of the telescopic mechanism 3-1. The other ends of the support arms 3-4 are connected to the inner side wall of the housing 4.

[0022] In order to improve the sealing performance between the plugging part 3-3 and the opening 5, in this embodiment, a rubber sleeve 6 is provided at the edge position of the opening 5.

[0023] In this embodiment, the plug is of a hollow structure with a cavity inside. A support frame 3-5 is connected to the inner side of the plugging part 3-3, and the top of the telescopic mechanism 3-1 is connected to the central position of the support frame 3-5.

[0024] In order to facilitate the timely discharge of the materials remaining in the magnetic separator body 1, in this embodiment, a plurality of discharge openings 3-6 are provided on the peripheral part of the inner side wall of the plugging part 3-3. A baffle 3-7 is hinged to the inner side of the upper edge of the discharge opening 3-6. The baffle 3-7 is used to close the discharge opening 3-6. A driving motor 3-8 is vertically arranged in the middle of the top of the adjusting part 3-2. A screw rod 3-9 is arranged at the output end of the driving motor 3-8. The bottom end of the screw rod 3-9 is rotatably connected to the top of the support frame 3-5. A sleeve 3-10 is threadedly connected to the screw rod 3-9. A plurality of connecting arms 3-11 are evenly distributed and rotatably arranged on the outer side wall of the sleeve 3-10. The other end of the connecting arm 3-11 is rotatably connected to the inner side of the baffle 3-7.

[0025] In this embodiment, the top end of the adjusting part 3-2 is of a conical structure.

[0026] The working principle and beneficial effects of the above technical solution are as follows:

[0027] During use, the lifting of the telescopic mechanism 3-1 is controlled by the controller to control the depth of the adjusting part 3-2 extending into the discharge port 2, so as to adjust the size of the gap between the edge of the discharge port 2 and the outer side wall of the adjusting part 3-2, and thus adjust the discharge amount at the discharge port 2. The materials then enter the housing 4 and fall out through the opening 5 at the bottom of the housing 4. When it is necessary to close the discharge port 2, the telescopic mechanism 3-1 is controlled to continue to extend, so that the outer side wall of the plugging part 3-3 is in full contact with the inner edge of the discharge port 2. After the magnetic separator body 1 stops working, when the materials in the machine completely fall into the bottom of the magnetic separator body 1, that is, the discharge port 2 area, the driving motor 3-8 is controlled by the controller to rotate, so as to lift the sleeve 3-10, thereby driving the connecting arm 3-11 to move to open the baffle 3-7, so as to discharge the remaining materials from the discharge opening 3-6. After the discharging is completed, the driving motor 3-8 is controlled to rotate in the reverse direction, so that the sleeve 3-10 descends, thereby driving the connecting arm 3-11 to move to push the baffle 3-7 to close the discharge opening 3-6.

[0028] Compared with the prior art, when the magnetic separator of the present utility model starts initial operation, it will not cause the problem of material accumulation at the discharge port 2, resulting in unstable discharge. At the same time, after stopping work, it will not cause the problem of remaining material siltation at the discharge port 2, resulting in incomplete discharge.
