Description

Technical Field

[0001] This utility model relates to the field of magnetic separator technology, specifically a drum device for a permanent magnet drum magnetic separator. Background Technology

[0002] In the fields of mineral processing, building materials, and environmental protection, permanent magnet drum separators are key equipment for separating magnetic and non-magnetic materials, and the drum device, as its core component, directly determines the magnetic separation efficiency and sorting accuracy. A permanent magnet drum separator typically consists of a permanent magnet system, a wear-resistant drum shell, a transmission assembly, a magnetic field adjustment mechanism, and a support structure. Its working principle is as follows: when the drum rotates, the magnetic field generated by the permanent magnet system penetrates the drum shell, adsorbing magnetic particles in the slurry. These particles are carried to the discharge end by the rotating drum, while non-magnetic particles are discharged from the bottom tailings outlet under the influence of gravity and slurry flow. By adjusting the drum speed and magnetic field range, the adsorption intensity and separation speed of the magnetic particles can be controlled. In terms of operation, operators set the drum speed and magnetic field parameters through the control system based on the magnetic characteristics of the material. After starting the equipment, the drum unit works in conjunction with the magnetic separator's feeding and discharging systems. During operation, the separation status can be monitored through an observation window. Periodic shutdowns are necessary to check the wear on the drum surface and clean any adhering materials.

[0003] However, the above-mentioned equipment has obvious shortcomings in use. The permanent magnet blocks of the traditional drum device are fixedly distributed and there is no slurry volume adjustment mechanism. When the slurry concentration is too high, the surface of the drum is quickly filled with magnetic particles, and subsequent particles cannot be adsorbed. Especially for fine magnetic minerals, the recovery rate is low. In view of this, we propose a drum device for permanent magnet drum magnetic separator. Utility Model Content

[0012] Compared with the prior art, this utility model provides a drum device for a permanent magnet drum separator, which has the following advantages: 1. The permanent magnet drum separator uses a drum device to improve the material recovery rate. It is equipped with a drum assembly. This assembly, together with the motor drive output shaft, drives the drum body to rotate. The permanent magnet blocks on the internal arc plate form a stable magnetic field, which adsorbs magnetic particles in the minerals. The feed hopper delivers the slurry evenly to the surface of the drum through the guide plate. Non-magnetic tailings slide down the guide plate to the tailings outlet hopper. Magnetic concentrate rotates with the drum and leaves the magnetic field at the concentrate outlet hopper. The spring rod in the square box pushes the partition to fit against the top of the drum, scraping off excess slurry and preventing magnetic field saturation. At the same time, the tailings and concentrate channels are separated by a tripod.

[0013] 2. The permanent magnet drum separator uses a drum device. To extend the service life of the drum, a cleaning component is installed. This component, in conjunction with a helical spring, pushes a straight rod to make the brush plate fit tightly against the drum surface. The brush bristles penetrate deep into the drum grooves to remove fine slag. Rubber scraper blades scrape away stubborn attached sludge through deformation. Intermittent scraper blades assist in breaking up agglomerated ore. At the same time, multiple sets of cylinders and straight rods form a stepped cleaning process to ensure that there are no dead corners in the cleaning of the entire circumference of the drum. The helical spring buffers the drum vibration and avoids drum wear caused by rigid contact. Attached Figure Description

[0018] Please see Figures 1-7 This utility model provides a technical solution: A drum device for a permanent magnet drum separator includes a support 1, on which a housing 2 is fixedly installed. The support 1 provides a stable support foundation for the entire device, and the housing 2 protects the internal components.

[0019] In one embodiment of this utility model, a roller assembly 3 is provided on the outer shell 2. The roller assembly 3 includes a mounting plate 31. The mounting plate 31 is fixedly mounted on the bracket 1. A motor 32 is fixedly mounted on the mounting plate 31. An output shaft 33 is fixedly mounted on the output end of the motor 32. A roller body 34 is fixedly mounted on the output shaft 33. A mounting bracket 35 is fixedly mounted on the output shaft 33. An arc-shaped plate 36 is fixedly mounted on the mounting bracket 35. A permanent magnet block 37 is fixedly mounted on the arc-shaped plate 36. A feeding funnel 38 is fixedly mounted above the outer shell 2. A guide plate 39 is fixedly mounted inside the outer shell 2. A square box 310 is fixedly mounted inside the outer shell 2. One end of a spring rod 311 is fixedly mounted inside the square box 310. The other end of the spring rod 311 is fixedly mounted... A partition plate 312 is fixedly installed. A tailings outlet funnel 313 and a concentrate outlet funnel 314 are fixedly installed at the bottom of the outer shell 2. A tripod 315 is fixedly installed inside the outer shell 2. Multiple sets of mounting plates 31, mounting brackets 35, permanent magnet blocks 37 and spring rods 311 are provided. Multiple sets of spring rods 311 are set inside the square box 310. The partition plate 312 slides inside the square box 310 and is attached to the top of the drum body 34. The mounting bracket 35, arc plate 36 and permanent magnet blocks 37 are set inside the drum body 34. The tailings outlet funnel 313, the concentrate outlet funnel 314 and the tripod 315 are set below the drum body 34. The tripod 315 is set between the tailings outlet funnel 313 and the concentrate outlet funnel 314.

[0020] In this embodiment, when in use, the motor 32 on the mounting plate 31 is started. The output end of the motor 32 drives the output shaft 33 to rotate, and the output shaft 33 drives the drum body 34 to rotate. At the same time, the mounting bracket 35 and the arc plate 36 on the output shaft 33 rotate together with the drum body 34. The multiple sets of permanent magnets 37 on the arc plate 36 form a stable magnetic field inside the drum body 34. The slurry to be sorted enters from the feed funnel 38 above the outer shell 2 and is evenly transported to the surface of the drum body 34 through the guide plate 39 inside the outer shell 2. Under the action of the magnetic field, the magnetic particles in the slurry are adsorbed onto the surface of the drum body 34, while the non-magnetic tailings slide down the guide plate 39 to the tailings below. As the drum body 34 rotates, the magnetic concentrate adsorbed on its surface is carried to the concentrate outlet funnel 314, where it is freed from the magnetic field and falls into the concentrate outlet funnel 314 for discharge. During this process, multiple sets of spring rods 311 inside the square box 310 push the partition 312 to slide inside the square box 310, so that the partition 312 is tightly attached to the top of the drum body 34, scraping off excess slurry, avoiding magnetic field adsorption saturation, and improving material recovery rate. The triangular frame 315 inside the outer shell 2 is located between the tailings outlet funnel 313 and the concentrate outlet funnel 314, which serves to separate the tailings and concentrate channels and prevent the two from mixing.

[0021] In one embodiment of this utility model, a cleaning assembly 4 is fixedly installed on the outer shell 2. The cleaning assembly 4 includes a cylinder 41. The cylinder 41 is fixedly installed on the outer shell 2. One end of a helical spring 42 is fixedly installed inside the cylinder 41. One end of a straight rod 43 is fixedly installed on the other end of the helical spring 42. A brush plate 44 is fixedly installed on the other end of the straight rod 43. A rubber scraper 45 is fixedly installed on one side of the brush plate 44, and an intermittent scraper 46 is fixedly installed on the other side of the brush plate 44. The cylinder 41, the helical spring 42, and the straight rod 43 are all fixedly installed. Multiple sets of rods 43 are provided. The helical spring 42 is located inside the cylinder 41. The straight rod 43 slides inside the cylinder 41. The brush plate 44, the rubber scraper 45, and the intermittent scraper 46 are attached to the surface of the drum body 34. The feed hopper 38 and the guide plate 39 are located above the drum body 34. The guide plate 39 is located above the tailings outlet hopper 313. The cylinder 41, the helical spring 42, the straight rod 43, the brush plate 44, the rubber scraper 45, and the intermittent scraper 46 are located above the concentrate outlet hopper 314.

[0022] In this embodiment, during the rotation of the roller body 34, the cleaning component 4 works synchronously. The helical spring 42 inside the cylinder 41 pushes the straight rod 43 to slide inside the cylinder 41, so that the brush plate 44 at the other end of the straight rod 43 is tightly attached to the surface of the roller body 34. The bristles on the brush plate 44 can penetrate into the texture of the roller body 34 to remove the fine slag remaining on the surface. The rubber scraper 45 can effectively scrape off stubborn attached sludge through its own deformation. The intermittent scraper 46 can help break up the lumpy mineral material. Multiple sets of cylinders 41 and straight rods 43 form a stepped cleaning, ensuring that there are no dead corners in the cleaning of the entire circumference of the roller body 34. At the same time, the helical spring 42 can buffer the vibration generated by the rotation of the roller body 34, avoid the rigid contact between the cleaning component 4 and the roller body 34 that causes roller wear, thereby extending the service life of the roller.
