Description

Technical Field

[0001] The utility model relates to a separation device, in particular to an ore magnetic separation device. Background Art

[0002] Magnetic separation of ore refers to a mineral processing method that utilizes magnetic differences between minerals to separate useful minerals from gangue minerals using magnetic separation equipment. Magnetic separation is based on the principle of magnetic differences in minerals: different minerals respond differently to magnetic fields. By introducing an uneven magnetic field, minerals with stronger magnetism are attracted to the field, while non-magnetic or weakly magnetic minerals are unaffected or less affected by the field, thereby achieving mineral separation. Magnetic separation of ore is a physical mineral processing method that utilizes magnetic differences in minerals for selective separation. It plays a vital role in the processing and refining of mineral resources. Magnetic separation can effectively separate useful magnetic minerals from non-magnetic ore minerals. Magnetic separation not only isolates useful minerals but also further purifies them, removing harmful impurities such as iron and improving their purity, which is critical for many subsequent industrial applications.

[0003] In the existing magnet screening process, workers first need to send large pieces of magnets into a crusher for initial crushing, and then send the crushed magnets into a magnetic separator for magnetic separation. However, this series of operations is cumbersome and inefficient, especially in large-scale production environments. Manual processing has become a bottleneck restricting capacity expansion. Although the magnetic separator can initially separate magnetic minerals from non-magnetic minerals based on magnetic differences, the magnetic and non-magnetic minerals in the screened materials may still be mixed together and not completely separated. Therefore, workers need to manually perform a second screening to ensure the complete separation of magnetic and non-magnetic minerals. This additional manual screening step is not only time-consuming and labor-intensive, but also under high-intensity labor conditions, fatigue may affect the accuracy and work efficiency of the screening, thereby affecting the production capacity of the entire production line.

DETAILED DESCRIPTION

[0020] The technical solution of the present utility model will be further described below with reference to the accompanying drawings.

[0021] Example: A magnetic separation device for ore, such as Figure 1 、 Figure 3 and Figure 4As shown, it includes a supporting base column 1, a conveyor belt 2, a first fixed rod 3, a feed box 4, a first motor 7, a spur gear 8, a rotating rod 9, a crushing wheel 10, a magnetic roller 11 and a magnetic sheet 12. There are four supporting base columns 1 that are symmetrical on the left and right sides. A conveyor belt 2 is provided between the left and right sides of the upper part of the four supporting base columns 1. The first fixed rods 3 are symmetrically connected to the front and back sides of the conveyor belt 2. A feed box 4 is fixedly connected between the left and right sides of the top of the two first fixed rods 3. The front side of the feed box 4 is fixedly connected to the first motor 7. The left and right sides of the inside of the feed box 4 are both rotatably connected to the rotating rods 9. The front sides of the two rotating rods 9 are both rotatably connected to the spur gears 8, and the two spur gears 8 are meshed with each other. The rotating rod 9 on the left It is rotatably connected to the output shaft of the first motor 7, and the two rotating rods 9 are fixedly connected with crushing wheels 10, and the two crushing wheels 10 are both located in the feed box 4. The two crushing wheels 10 crush large pieces of ore, so that magnetic minerals are easier to be adsorbed by the magnetic separator, and non-magnetic minerals are easily excluded, thereby improving the efficiency and accuracy of magnetic separation. A magnetic roller 11 is rotatably connected to the outer side of the rotating shaft on the left side of the conveyor belt 2, and a magnetic sheet 12 is fixedly connected between the two supporting base columns 1 on the left side of the conveyor belt 2, and the magnetic sheet 12 is located at the bottom of the magnetic roller 11. The magnetic roller 11 and the magnetic sheet 12 are both made of neodymium iron boron material, which can achieve efficient magnetic separation and improve the accuracy and efficiency of magnetic separation.

[0022] like Figure 1-Figure 2 As shown, it also includes a second fixed rod 5 and an ore conveyor 6. The ore can be directly dropped into the feed box 4 under the transportation of the ore conveyor belt 6, realizing an automated ore feeding process and preparing to be crushed and magnetically separated. The second fixed rod 5 is fixedly connected to the right side of the feed box 4. The ore conveyor 6 is provided on the upper part of the second fixed rod 5, and the conveyor belt of the ore conveyor 6 has its own partition bar. The support legs at the bottom of the ore conveyor 6 are at the same horizontal height as the bottom of the second fixed rod 5. The ore conveyor 6 is arranged as a whole in an inclined manner. The conveying position of the ore conveyor 6 to the highest point is adjacent to the upper end part of the right side of the feed box 4.

[0023] like Figure 3 As shown, a material receiving box 13 is also included. Two material receiving boxes 13 are provided below the conveyor belt 2 , one of which is located at an outer side below the conveyor belt 2 , and the other is located at an inner side below the conveyor belt 2 .

[0024] like Figure 4 As shown, it also includes an electric push rod 14 and a sieve plate 15. The electric push rod 14 is fixedly connected to the left side of the feed box 4. The sieve plate 15 is fixed to the telescopic rod of the electric push rod 14, and the sieve plate 15 is slidably connected to the left side of the feed box 4. The electric push rod 14 drives the sieve plate 15 to start sliding left and right. This action is intended to make the ore more evenly distributed on the conveyor belt 2, thereby improving the processing efficiency and accuracy of the entire magnetic separation device.

[0025] like Figure 3As shown, a buffer plate 16 is also included. The buffer plate 16 is fixedly connected to the lower part of the feed box 4, and the buffer plate 16 is in an inverted V shape. The arched buffer plate 16 helps to evenly distribute the ore on the surface of the conveyor belt, avoiding the accumulation of materials on one side, and ensuring that the materials can smoothly and evenly enter the subsequent processing process.

[0026] When the device needs to be used, the staff needs to first place the large pieces of ore on the ore conveyor 6 and make the ore contact the spacer on the conveyor belt to prevent the ore from falling. Then the motor on the ore conveyor 6 is started, and the motor drives the entire ore conveyor 6 to start operating. The large pieces of ore move to the upper left with the operation of the ore conveyor 6 to achieve transportation and eventually fall into the feed box 4; then the staff starts the first motor 7, and the first motor 7 drives the rotating rod 9 on the output shaft to start rotating, and the crushing wheel 10 on the rotating rod 9 rotates accordingly. At the same time, the spur gear 8 on the rotating rod 9 of the first motor 7 starts to rotate, and the mutual engagement of the two spur gears 8 drives the other rotating rod 9 and the crushing wheel 10 on it to start rotating, and together the ore in the feed box 4 is crushed, and the crushed ore falls downward and is slowly crushed. Thanks to the action of the punch plate 16, the ore is dispersed, and the upwardly convex arc design of the middle part of the buffer plate 16 prevents the ore from falling directly vertically, reducing the impact on the conveyor belt 2; then the staff starts the motor on the conveyor belt 2, and the crushed ore begins to move to the left with the operation of the conveyor belt 2. At the same time, the staff starts the electric push rod 14, and the telescopic rod of the electric push rod 14 drives the screen plate 15 to slide left and right, so as to evenly distribute the crushed ore; when the crushed ore passes through the magnetic separation area, the non-magnetic ore minerals move with the conveyor belt 2 and naturally fall into the receiving box 13 on the outside below the conveyor belt 2, while the magnetic ore minerals are adsorbed on the conveyor belt 2 when passing the magnetic roller 11 below the conveyor belt 2. Subsequently, these adsorbed magnets pass through the magnetic sheet 12 and are further adsorbed and fixed. When the magnetic ores move with the conveyor belt 2 to the end of the magnetic sheet 12 and leave the suction range of the magnetic sheet 12, they fall off the conveyor belt 2 and fall into the material receiving box 13 to the right below the magnetic sheet 12, realizing the effective separation and collection of non-magnetic and magnetic ore minerals.
