Detailed Embodiments

[0016] In order to better understand the present utility model, the content of the present utility model will be further clarified below in conjunction with embodiments. However, the content of the present utility model is not limited to the following embodiments only.

[0017] Combined with Figure 1 , the utility model is a small magnetic separation device, comprising a vertically arranged separation tube 3, the separation tube 3 can be directly replaced by a burette, a feeding hopper 10 is arranged at the upper end of the separation tube 3, vertical beams 2 arranged parallel to the separation tube 3 are respectively arranged on both sides of the separation tube 3, the lower ends of the vertical beams 2 are respectively fixedly connected to the base 1, the base 1 is a rectangular frame structure, the lower ends of the vertical beams 2 are respectively connected to the long sides of the base 1, a cross beam 6 is arranged between the upper ends of the vertical beams 2, a sleeve 7 is sleeved on the cross beam 6, the sleeve 7 is rotatably connected to the cross beam 6, a support 8 arranged vertically to the cross beam 6 is connected below the sleeve 7 through a connecting rod, a motor 9 is arranged at the rear end of the support 8, a pipe seat 11 is arranged at the front end of the support 8, a meshing drive sleeve 12 is arranged below the pipe seat 11, and a drive sleeve 12 is arranged between the pipe seats 11. The middle parts of the seat 11 and the driving sleeve 12 are correspondingly provided with pipe holes for the separation pipe 3 to pass through. The central axes of the pipe seat 11, the driving sleeve 12 and the separation pipe 3 are in a straight line. The separation pipe 3 is fixedly connected to the pipe seat 11. The motor 9 is connected to the driving sleeve 12 through a transmission member. The motor 9 can drive the pipe seat 11 to drive the separation pipe 3 to rotate through the driving sleeve 12. A moving rod 4 is provided under the cross beam 6. The two ends of the moving rod 4 are respectively movably connected to the vertical beam 2. Magnets 16 are arranged on the left and right sides of the moving rod 4 at intervals. The magnets 16 are correspondingly arranged on both sides of the separation pipe 3. The small magnetic separation device of the utility model has a simple structure, a small footprint, and low power. The device can be used to separate weakly magnetic minerals and non-magnetic minerals, and can also reduce the workload of manual grinding of ferromagnetic materials and improve work efficiency.

[0018] As an optional design, the small magnetic separation device is preferably provided with a cross bar 5 above the movable rod 4, and both ends of the cross bar 5 are respectively connected to the vertical beam 2, and an arc plate 15 extending in the vertical direction is provided on the cross bar 5, and the curvature of the arc plate 15 is matched with the outer cylindrical surface of the separation tube 3. The arc plate 15 can protect the separation tube 3 and limit the separation tube 3.

[0019] As an optional design, the small magnetic separation device is preferably provided with a vertical rod 13 extending vertically downward on one side of the sleeve 7, and a magnetic suction block 14 matching the magnetic suction cup arranged under the cross bar 5 is provided at the lower end of the vertical rod 13. The magnetic suction cup is arranged at the lower rear of the cross bar 5, and the vertical rod 13 is arranged in front of the cross bar 5. When the magnetic suction block 14 at the lower end of the vertical rod 13 is adsorbed on the magnetic suction cup, the position of the sleeve 7 is locked. In this state, the sleeve 7 cannot rotate around the cross beam 6, and finally the position of the selection tube 3 is locked.

[0020] As an alternative design, it is preferred that in the small magnetic separation device, a torsion spring is sleeved on the cross beam 6. One end of the torsion spring is fixedly connected to the cross beam 6, and the other end of the torsion spring is fixedly connected to the inner wall of the sleeve 7. When the sleeve 7 rotates around the cross beam 6, the torsion spring accumulates potential energy to a certain extent and hinders the further rotation of the sleeve 7 around the cross beam 6.

[0021] As an alternative design, it is preferred that in the small magnetic separation device, the magnet 16 is in a long strip structure. Claws for clamping the magnet 16 are provided on the moving rod 4. The magnet 16 is detachably connected to the claws, which facilitates the replacement of magnets 16 of different specifications. The performance and grade of the magnet 16 depend on specific requirements. The thickness and length of the magnet 16 are determined according to the specifications of the separation tube 3, and the total length of the magnet 16 does not exceed one-third of the total length of the separation tube 3.

[0022] As an alternative design, it is preferred that in the small magnetic separation device, the vertical beam 2 can vertically lift and adjust the height of the cross beam 6, which facilitates adjusting the height of the cross beam according to the length of the separation tube 3.

[0023] The working process of the present utility model is as follows:

[0024] During operation, according to the length of the separation tube 3, adjust the height of the moving rod 4 so that the magnet 16 is set at an appropriate height relative to the separation tube 3. Weigh 0.2 - 0.5 grams of sample powder into a 100 ml small beaker, rinse the inner wall of the small beaker with a small amount of water, place a 500 ml large beaker under the separation tube 3 to collect the waste liquid, clamp the rubber head at the bottom of the separation tube 3 with a clip, leaving a small hole the size of a needle tip. Start the motor 9. The motor 9 drives the tube seat 11 to rotate around its center through the driving sleeve 12. The rotation of the tube seat 11 drives the separation tube 3 to rotate. Through the rotation of the separation tube 3, the substances can be fully mixed with the water flow, enhancing the magnetic separation effect. At the same time, it can prevent magnetic substances from accumulating inside the separation tube 3 due to their own mass, thus affecting the magnetic separation. First, pour distilled water along the wall of the feed hopper 10 into the separation tube 3 to heat and rinse the separation tube 3, so that the water level in the separation tube 3 is above the magnet 16 (the water level line is at about 2 / 3 of the height of a 25 ml burette). Hold the small beaker in one hand, hold a small magnet in the palm close to the bottom of the small beaker, place the mouth of the small beaker against the feed hopper 10, and use the wash bottle in the other hand to gently rinse the sample in the small beaker. The non-magnetic substances in the small beaker first enter the separation tube 3 along the feed hopper 10, and the magnetic substances are adsorbed by the small magnet and concentrated at the bottom of the small beaker. The non-magnetic substances flow downward along the separation tube 3 and finally are collected in the large beaker below the separation tube 3. Rinse the separation tube 3, then remove the small magnet in the palm, use the wash bottle to rinse the small beaker with water, and the magnetic substances at the bottom of the small beaker enter the separation tube 3 along the feed hopper 10. Under the action of the water flow and the rotation of the separation tube 3, when the magnetic substances flow to the position corresponding to the magnet 16 along the separation tube 3, the magnetic substances are adsorbed on the inner wall of the separation tube 3 by the magnet 16. Then pull the lower end of the separation tube 3, the sleeve 7 rotates around the cross beam 6, and the separation tube 3 moves away from the magnet 16. The magnetic substances in the separation tube 3 are no longer under the magnetic adsorption of the magnet 16. Slowly rinse the separation tube 3 with distilled water, and use a clean Erlenmeyer flask to catch the magnetic substances washed out by the distilled water at the bottom of the separation tube 3 until all the magnetic substances are washed into the Erlenmeyer flask. Then analyze the content of the magnetic substances in the Erlenmeyer flask by chemical methods, and finally calculate the content of the magnetic substances in the sample. The small magnetic separation device disclosed by the present utility model has a simple structure, occupies a small area, and has a low power. Using this device, the separation of weakly magnetic minerals and non-magnetic minerals can be achieved.

[0025] The above description is only for the application implementation mode of the present utility model, but the protection scope of the present utility model is not limited thereto. It cannot be used to limit the scope of the rights of the present utility model. Any equivalent changes made according to the technical solution of the present utility model should be covered within the protection scope of the present utility model.
