Description

Technical Field

[0001] This utility model belongs to the technical field of impurity removal equipment, specifically a magnetic separation and impurity removal device for diamond micro powder production. Background Technology

[0002] Diamond micron powder refers to diamond particles with a particle size finer than 36 / 54 micrometers. There are single-crystal diamond micron powder and polycrystalline diamond micron powder. Due to the large output and wide range of applications of single-crystal diamond micron powder, the industry generally refers to diamond micron powder specifically as single-crystal diamond micron powder. Single-crystal diamond micron powder is produced by hydrostatic pressing of synthetic single-crystal diamond abrasive grains, which are crushed and shaped using special processes for superhard materials. Currently, when producing diamond micron powder, magnetic separation is required to remove impurities.

[0003] Existing magnetic separation and impurity removal equipment for diamond micron powder production typically involves feeding diamond micron powder into a hopper, allowing it to fall onto a conveyor belt. A drive motor then rotates the conveyor belt to transport the powder. Simultaneously, an electromagnet generates a magnetic field near the discharge pipe on the conveyor belt. When the powder passes through this magnetic field, magnetic materials are attracted to the conveyor belt, while non-magnetic materials continue to be transported. Upon reaching the corresponding discharge pipe, a scraper scrapes the powder off and discharges it, thus achieving magnetic separation of the diamond micron powder.

[0004] However, in actual use, diamond powder may accumulate when it falls from the hopper onto the conveyor belt. This results in the powder on the top layer being far from the magnetic field, which reduces the attraction of the magnetic field to the powder on the top layer. Consequently, the magnetic field fails to attract magnetic impurities, affecting the magnetic separation effect. Utility Model Content

[0025] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0026] like Figure 1-4As shown, this utility model provides a technical solution: a magnetic separation and impurity removal device for diamond micron powder production, including a body 1, a conveyor belt 2 on one side of the body 1, a hopper 3 on one side of the body 1, a discharge pipe 4 on one side of the body 1, an impurity discharge pipe 5 on one side of the body 1, and a leveling device 6 on one side of the body 1. The leveling device 6 includes a support rod 61, a connecting device 7 between the support rod 61 and the body 1, a motor 62 fixedly connected to one side of the support rod 61, a circular hole rod 63 fixedly connected to the output end of the motor 62 via a circular shaft, a circular rod 65 slidably connected to the inner wall of the circular hole rod 63, a rectangular rod 66 fixedly connected to one end of the circular rod 65, and multiple push rods 67 fixedly connected to the side of the rectangular rod 66 near the conveyor belt 2. The surface of the push rods 67 is flush with the conveyor belt 2. The surface of the round rod 65 is close to the surface of the rectangular rod 66, and the two ends of the spring 610 are fixedly connected to the round hole rod 63 and the rectangular rod 66 respectively. By setting the leveling device 6, the motor 62 is started first to drive the round hole rod 63 to rotate, so that the round hole rod 63 drives the rectangular rod 66 to rotate through the round rod 65, so that the rectangular rod 66 drives multiple push rods 67 to rotate, so that the multiple push rods 67 come into contact with the accumulated micro powder during the rotation and push the accumulated micro powder to disperse it, so that the micro powder is evenly spread on the conveyor belt 2, thereby achieving the leveling treatment of the accumulated micro powder. This reduces the accumulation of diamond micro powder after it falls onto the conveyor belt 2 through the hopper 3, which reduces the attraction of the magnetic field to the top layer of accumulated micro powder, causing the magnetic field to fail to attract magnetic impurities, thus improving the magnetic separation effect of diamond micro powder.

[0027] Specifically, such as Figure 2 and Figure 3 As shown, a plurality of through holes 68 are provided on one side of the rectangular rod 66. The plurality of through holes 68 are arranged at equal intervals. By setting the through holes 68, the fine powder scraped by the rectangular rod 66 can be discharged through the multiple through holes 68, reducing the accumulation of fine powder on one side of the rectangular rod 66 when it is pushed by the rectangular rod 66. A circular plate 69 is fixedly connected to the end of the round rod 65 away from the rectangular rod 66. The surface of the circular plate 69 is larger than the inner wall of the round hole rod 63. By setting the circular plate 69, the round rod 65 can be intercepted during the movement, reducing the possibility of the round rod 65 detaching from the inside of the round hole rod 63 when it is driven by the spring 610. A reinforcing block 64 is fixedly connected to the side of the round hole rod 63 near the motor 62. The reinforcing block 64 is fixed to the round shaft at the output end of the motor 62. By setting the reinforcing block 64, the connection strength between the round hole rod 63 and the shaft of the motor 62 can be increased, reducing the possibility of the round hole rod 63 separating from the shaft of the motor 62 during use.

[0028] Specifically, such as Figure 3 and Figure 4As shown, the connecting device 7 includes a rectangular tube 71, which is fixedly connected to the machine body 1. A threaded hole 72 is provided on one side of the rectangular tube 71, and a bolt 73 is threadedly connected to the inner wall of the threaded hole 72. The surface of the support rod 61 is slidably connected to the inner wall of the rectangular tube 71. A circular hole 76 is provided on one side of the support rod 61. The size and shape of the bolt 73 are adapted to the size and shape of the inner wall of the circular hole 76. By setting the connecting device 7, the support rod 61 is first manually moved to the position of being inserted into the rectangular tube 71, so that the inner wall of the circular hole 76 coincides with the inner wall of the threaded hole 72. At this time, the bolt 73 is manually turned into the position inside the threaded hole 72 and the circular hole 76 to fix the support rod 61, thereby achieving the assembly and fixation between the flattening device 6 and the machine body 1. At the same time, the flattening device 6 can be disassembled later, which improves the flexibility of use of the flattening device 6 and the convenience of later maintenance.

[0029] Specifically, such as Figure 3 and Figure 4 As shown, one end of the bolt 73 is fixedly connected to multiple auxiliary rods 74, which are arranged at equal intervals. By setting the auxiliary rods 74, a force point can be provided for personnel to manually rotate the bolt 73, improving the convenience of manual rotation of the bolt 73. A limit block 77 is fixedly connected to one side of the support rod 61, and a limit groove 75 is opened on one side of the rectangular tube 71. The surface size and shape of the limit block 77 are adapted to the inner wall size and shape of the limit groove 75. By setting the limit block 77 and the limit groove 75, the limit block 77 can be inserted into the interior of the limit groove 75 to assist in limiting the support rod 61, reducing the shaking of the support rod 61 inside the rectangular tube 71, and further improving the connection stability between the support rod 61 and the rectangular tube 71.

[0030] The working principle of this utility model is as follows:

[0031] S1. First, diamond micro powder is fed into hopper 3, allowing it to fall onto conveyor belt 2. Then, the drive motor drives conveyor belt 2 to operate and transport the micro powder. At the same time, an electromagnet generates a magnetic field near the discharge pipe 4 on conveyor belt 2. When the micro powder passes through the magnetic field area, magnetic materials are adsorbed onto conveyor belt 2, while non-magnetic materials continue to be transported forward. When the powder reaches the corresponding discharge pipe 5, it is scraped off by a scraper and discharged into the discharge pipe 5, thus achieving magnetic separation of diamond micro powder.

[0032] S2. First, manually move the support rod 61 to the position inside the rectangular tube 71 so that the inner wall of the circular hole 76 coincides with the inner wall of the threaded hole 72. Then, manually turn the bolt 73 into the positions inside the threaded hole 72 and the circular hole 76 to fix the support rod 61, thereby achieving the assembly and fixation between the leveling device 6 and the machine body 1. At this time, start the motor 62 to drive the circular hole rod 63 to rotate, so that the circular hole rod 63 drives the rectangular rod 66 to rotate through the circular rod 65, so that the rectangular rod 66 drives multiple push rods 67 to rotate, so that the multiple push rods 67 contact the accumulated micro powder during the rotation process and push the accumulated micro powder to disperse it, so that the micro powder is evenly spread on the conveyor belt 2, thereby achieving the leveling treatment of the accumulated micro powder.
