Description

Technical Field

[0001] This application relates to the technical field of wet magnetic separators, and in particular to a slurry electromagnetic wet magnetic separator. Background Art

[0002] Magnetic separators are one of the most widely used and highly versatile machine types in the industrial sector, suitable for the separation of substances with magnetic differences. Magnetic separators are widely used in industries such as mining, timber, ceramics, chemistry, and food. For the mining industry, magnetic separators are applicable to the wet or dry magnetic separation of materials such as manganese ore, magnetite, pyrrhotite, roasted ore, ilmenite, and hematite limonite, and are also used for the iron removal operation of materials such as coal, non-metallic minerals, and building materials.

[0003] Electromagnetic wet magnetic separators are widely used in departments such as ore dressing, coal washing, and chemical industry, for wet separation of strongly magnetic minerals, and classifying minerals into two products: magnetic substances and non-magnetic substances.

[0004] After the existing electromagnetic wet magnetic separator adsorbs the magnetic impurities inside the slurry on the inner wall of the magnetic concentrating medium, it flushes and cleans the magnetic impurities on the inner wall of the magnetic concentrating medium by means of water flow. However, it is difficult for water flow flushing to completely wash away the magnetic impurities on the inner wall of the magnetic concentrating medium, and the remaining magnetic impurities will affect the adsorption effect of the magnetic concentrating medium on the magnetic impurities in the slurry later. Summary of the Utility Model

[0005] In order to be able to completely clean the magnetic impurities on the inner wall of the magnetic concentrating medium, this application provides a slurry electromagnetic wet magnetic separator.

[0006] A slurry electromagnetic wet magnetic separator provided by this application adopts the following technical solutions: including a magnetic separator body, an exciting coil and a magnetic concentrating medium body are installed on the inner wall of the magnetic separator body, a fixing rod is arranged inside the magnetic concentrating medium body, four transmission rods are fixedly connected to the outer surface of the fixing rod, two scrapers are arranged inside the magnetic concentrating medium body, and one end of each transmission rod away from the fixing rod is fixedly connected to the side surface of the corresponding scraper. A long rod is arranged above the magnetic separator body, and gears are fixedly connected to the outer surfaces of the fixing rod and the long rod.

[0007] Optionally, a toothed belt is arranged above the magnetic separator body, and the outer surface of each gear is meshed with the inner wall of the toothed belt.

[0008] Optionally, a motor is installed on the upper surface of the magnetic separator body, and the bottom end of the long rod is fixedly connected to the output end of the motor.

[0009] Optionally, a slurry discharge module is installed on the upper surface of the magnetic separator body, and the outer surface of the fixing rod is rotationally connected to the inner wall of the slurry discharge module.

[0010] Optionally, a support is fixedly connected to the upper surface of the magnetic separator body. The outer surface of the long rod is rotatably connected to the inner wall of the support. A fixing frame is fixedly connected to the upper surface of the magnetic separator body. The outer surface of the fixing rod is rotatably connected to the inner wall of the fixing frame.

[0012] Optionally, four springs are fixedly connected to the bottom surface of the magnetic separator body. The bottom end of each spring is fixedly connected to the upper surface of the corresponding fixing plate.

[0013] In summary, the present application includes the following beneficial technical effects:

[0014] 1. By setting components such as a fixing rod, a transmission rod, and a scraper, the exciting coil is energized with direct current to form an induced magnetic field. When the slurry containing magnetic impurities passes through the magnetic concentrating medium body, the magnetic impurities will be adsorbed on the inner wall of the magnetic concentrating medium body. The rotation of the gear can drive the fixing rod to rotate, drive the transmission rod to rotate through the fixing rod, and drive two scrapers to rotate on the inner wall of the magnetic concentrating medium body through the transmission rod. The magnetic impurities adsorbed on the inner wall of the magnetic concentrating medium body can be cleaned by the scraper, so as to achieve the effect of completely cleaning the magnetic impurities on the inner wall of the magnetic concentrating medium body. Then, according to the existing technology, the magnetic impurities can be discharged to the outside of the magnetic separator body by the water flow flushing through the drain pipe.

[0015] 2. By setting components such as damping rods, fixing plates, and springs, the magnetic separator body can be easily moved through the universal wheels. When moving the magnetic separator body on an uneven road surface, the universal wheels will drive the fixing plate to move upward, the fixing plate drives the spring to compress, and drives the damping rod to contract. Through the cooperation of the damping rod and the spring, the fixing plate can be shock-absorbed, so as to prevent the magnetic separator body from shaking violently when moving the magnetic separator body, and prevent the parts inside the magnetic separator body from being damaged due to shaking.
