Description

Technical Field

[0001] This utility model relates to the field of wet magnetic separator technology, specifically a wet magnetic separator. Background Technology

[0002] When producing iron ore, metallurgical enterprises need to grind the collected ore into a slurry and then extract the iron. In order to obtain high-grade iron, magnetic separators are generally used to separate the iron.

[0003] A wet magnetic separator, as disclosed in authorization announcement number CN221536961U, includes a material trough, a magnetic roller, and a scraping mechanism. A receiving hopper is located on the left side of the material trough, and an inclined guide scraper is positioned above the left side of the trough. The higher end of the guide scraper contacts the surface of the magnetic roller, while the lower end connects to the receiving hopper. By adopting the above technical solution, the beneficial effects of this utility model are: stable unloading, improved unloading and mineral processing efficiency, etc.

[0004] Although the aforementioned patent includes a scraping mechanism, it is located on the side of the trough away from the receiving hopper. When the roller rotates clockwise, the scraping mechanism on the right side can scrape off the material, but because its mounting base and support structure are located directly below the scraping trajectory, it completely blocks the material's falling channel. As a result, the scraped material cannot be discharged smoothly by gravity and instead accumulates in the narrow space formed by the back of the scraper and the equipment housing. This accumulation inevitably causes serious blockage, hinders equipment operation, and causes abnormal wear on the roller and scraper, ultimately rendering the scraping function completely ineffective. Utility Model Content

[0005] The purpose of this invention is to provide a wet magnetic separator to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A wet magnetic separator, comprising A tank body with rollers installed on its inner side, and a drive mechanism is installed between the rollers and the tank body; The ore inlet and concentrate outlet are respectively located on both sides of the tank body; The tank is equipped with a cleaning mechanism located above the concentrate inlet on one side.

[0007] Preferably, the drive mechanism includes a frame symmetrically and fixedly connected to the outside of both sides of the tank, and a motor is fixedly connected to the outside of the left side of the frame, with the output shaft of the motor fixedly connected to the roller. Preferably, the cleaning mechanism includes mounting frames symmetrically fixedly connected to both sides of the top of the concentrate inlet of the tank, and a water spray pipe fixedly connected between the two mounting frames, with one end of the water spray pipe passing through the left mounting frame and fixedly connected to a water pipe connector. Preferably, the cleaning mechanism further includes a top frame fixedly connected to the top of the two frames near the mounting frame, and a plurality of spring telescopic rods evenly distributed at the bottom of the top frame.

Preferably, the cleaning mechanism further includes a locking screw threaded to the outer side of the upper end of the two mounting brackets, and a swing arm disposed on the inner side of the upper end of the two mounting brackets. The end of the locking screw passes through the mounting bracket and is fixedly connected to a bushing. One end of the swing arm is provided with a rotating groove that matches the bushing. The other ends of the two swing arms are rotatably connected to a brush roller through a bearing. The pressure roller slides in contact with the swing arm. A second motor is fixedly connected to the outside of the left swing arm away from the rotating groove. The output shaft of the second motor is fixedly connected to the brush roller. Preferably, the bottom end of the water spray pipe and the side near the brush roller are evenly distributed with a number of water spray holes.

[0008] Compared with the prior art, the beneficial effects of this utility model are: This wet magnetic separator, through the combined use of water spray pipes and brush rollers, achieves a dual cleaning effect of high-pressure rinsing and mechanical brushing of the minerals adsorbed on the roller surface. It effectively solves the problems of material blockage, wear and functional failure caused by unreasonable layout of the scraping mechanism in the existing technology, and ensures that the separated minerals fall into the concentrate inlet unimpeded.

[0012] 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.

[0013] like Figure 1-5 As shown, this utility model provides a technical solution: A wet magnetic separator includes a tank 1 with a drum 2 inside. A drive mechanism is provided between the drum 2 and the tank 1. The drive mechanism includes frames 6 symmetrically fixedly connected to the outside of both sides of the tank 1. A motor 7 is fixedly connected to the outside of the left frame 6. The output shaft of the motor 7 is fixedly connected to the drum 2. An inlet 4 and a concentrate inlet 5 are respectively located on both sides of the tank 1. A cleaning mechanism is provided above the side of the tank 1 where the concentrate inlet 5 is located. The cleaning mechanism includes mounting brackets 8 symmetrically fixedly connected to the top sides of the tank 1 where the concentrate inlet 5 is located. A water spray pipe 9 is fixedly connected between the two mounting brackets 8. One end of the water spray pipe 9 passes through the left mounting bracket 8 and is fixedly connected to a water pipe connector 10. The cleaning mechanism also includes a top frame 11 fixedly connected to the top of the side of the two frames 6 near the mounting brackets 8. A number of spring telescopic rods 12 are fixedly connected to the bottom of the spring telescopic rods 12. A lifting frame 13 is fixedly connected to both sides of the lifting frame 13 via bearings. A pressure roller 14 is rotatably connected to both sides of the lifting frame 13. The cleaning mechanism also includes a locking screw 15 threaded to the outer side of the upper end of two mounting frames 8, and a swing arm 16 located on the inner side of the upper end of the two mounting frames 8. The end of the locking screw 15 passes through the mounting frame 8 and is fixedly connected to a bushing 17. One end of the swing arm 16 is provided with a rotating groove 18 that matches the bushing 17. The other ends of the two swing arms 16 are rotatably connected to a brush roller 19 via bearings. The pressure roller 14 slides in contact with the swing arm 16. A motor 2 3 is fixedly connected to the outside of the side of the left swing arm 16 away from the rotating groove 18. The output shaft of the motor 2 3 is fixedly connected to the brush roller 19. A number of water spray holes are evenly distributed at the bottom end of the water spray pipe 9 and on the side close to the brush roller 19. In this embodiment, the combined use of water spray pipe 9 and brush roller 19 achieves a dual cleaning effect of high-pressure rinsing and mechanical brushing of the minerals adsorbed on the surface of roller 2. This effectively solves the problems of material blockage, wear and functional failure caused by unreasonable layout of scraping mechanism in the prior art, and ensures that the separated minerals fall into concentrate inlet 5 unimpeded.

[0014] Furthermore, the use of the spring telescopic rod 12 in conjunction with the pressure roller 14 provides a constant elastic pressure that can adapt to the undulations of the roller 2 surface, so that the brush roller 19 can always maintain uniform contact with the roller 2 surface, thus solving the problems of unstable unloading, roller surface wear, and poor mineral processing effect caused by uneven pressure in the rigid scraping mechanism.

[0015] Working principle: The slurry enters the tank 1 through the inlet 4. The motor 7 of the drive mechanism starts and drives the drum 2 to rotate. During the rotation, the magnetic field generated by the internal magnetic system of the drum 2 adsorbs magnetic minerals in the slurry onto the surface of the drum 2, while non-magnetic minerals are discharged as tailings from the other side of the tank 1. As the drum 2 with adsorbed magnetic minerals rotates, it gradually detaches from the slurry surface and moves towards the concentrate outlet 5. At this time, the cleaning mechanism starts to work. Its water spray pipe 9 is connected to a high-pressure water source through the water pipe connector 10 and sprays water onto the surface of the drum 2 through several water spray holes at its bottom and near the brush roller 19 for pre-rinsing and wetting. At the same time, the motor 3 starts and drives the brush roller 19 to rotate. The brush roller 19, with the cooperation of the pressure roller 14, is brushed against the surface of the drum 2 by the elastic pressure provided by the spring telescopic rod 12. The pressure roller 14 is connected to the spring through the lifting frame 13. The spring telescopic rod 12 is connected and can adaptively adjust its position according to the undulation of the roller 2 surface to ensure that the brush roller 19 maintains a constant contact pressure with the roller 2 surface. The magnetic minerals that are brushed off fall into the concentrate inlet 5 under the action of gravity and water flow to complete the collection. During the entire cleaning process, the swing arm 16 can rotate around the bushing 17 at the end of the locking screw 15 in the rotating groove 18 to achieve adaptive adjustment of the angle of the brush roller 19, and fix its working position by the locking screw 15. When it is necessary to replace or maintain the brush roller 19, loosen the two locking screws 15 so that the bushing 17 at the end of the swing arm 16 is removed from the rotating groove 18 of the swing arm 16, and the entire swing arm 16 together with the brush roller 19 can be removed from the mounting frame 8 for subsequent operations. After maintenance, align the rotating groove 18 of the swing arm 16 with the bushing 17, insert it and tighten the locking screw 15 to restore the working state.
