Description

Technical Field

[0001] The utility model relates to the technical field of diamond micropowder production, in particular to a diamond micropowder magnetic separation device. Background Art

[0002] Diamond micropowder is a new type of superhard and ultrafine abrasive formed by special processing of artificial diamond single crystals. It is an ideal raw material for grinding and polishing high-hardness materials such as cemented carbide, ceramics, gemstones, optical glass, etc. Diamond micropowder and its products are widely used in automobiles, machinery, electronics, aviation, aerospace, optical instruments, glass, ceramics, petroleum, geology and other fields. In the production of diamond micropowder, it is generally necessary to use a magnetic separation device to magnetically separate the diamond micropowder to facilitate further processing or treatment of the diamond micropowder.

[0003] In Chinese patent publication number CN220425604U, a diamond powder magnetic separation device is disclosed. An electric push rod drives an electromagnet to move in a vertical direction to adjust the distance between the electromagnet and the diamond powder. A cylinder drives a knocking plate to knock and vibrate the material on both sides of the electromagnet so that the magnetic material in the diamond powder can be fully exposed, thereby facilitating adsorption and screening by a magnetic separation mechanism. However, when magnetically separating diamond powder, the above-mentioned magnetic separation device generally lays the diamond powder on a conveyor belt. During the process of conveying the diamond powder on the conveyor belt, the diamond powder is magnetically separated by a magnetic separation mechanism. However, when manually laying the diamond powder, due to human factors, the diamond powder is often difficult to be evenly laid on the conveyor belt and easily accumulates on the conveyor belt. As a result, after the magnetic separation mechanism magnetically separates the diamond powder on the surface, it is difficult to magnetically separate the diamond powder in the interior, resulting in poor magnetic separation effect and being detrimental to efficient screening of diamond powder.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0027] The utility model provides Figure 1-Figure 5 The diamond powder magnetic separation device shown includes a magnetic separation box 1 with a magnetic separation cavity inside. The top of the magnetic separation box 1 is provided with a feed port, the bottom is installed with a discharge pipe 16, and a non-magnetic powder collection box 7 corresponding to the discharge pipe 16 is provided below the magnetic separation box 1. A magnetic separation component 10 and an adjustment structure for driving the magnetic separation component 10 to move into and / or out of the magnetic separation cavity are provided on one side of the magnetic separation box 1. A placement rack 9 is provided on one side of the magnetic separation box 1, and a magnetic powder collection box 8 is placed on the placement rack 9.

[0028] The magnetic separation box 1 is also provided with a scattering component for stirring and dispersing the diamond powder, and the scattering component includes a roller 14 rotatably installed in the magnetic separation chamber, and a second motor 12 fixed to one side of the magnetic separation box 1. The second motor 12 is used to drive the roller 14 to rotate, and a plurality of dispersion blades 20 distributed in a ring array are installed on the outer circumferential side wall of the roller 14. The material receiving surfaces of the plurality of dispersion blades 20 are all concave inward to form an arc-shaped storage area.

[0029] Specifically, such as Figure 1-Figure 5 As shown, the magnetic separation component 10 includes a mounting plate 101, and a plurality of electromagnets 102 are provided on one side of the mounting plate 101. A slot is opened on one side of the magnetic separation box 1 for the plurality of electromagnets 102 to move into and / or out of the magnetic separation cavity, and when the electromagnet 102 moves into the magnetic separation cavity, the slot is sealed by the mounting plate 101.

[0030] During the magnetic separation of diamond powder, the magnetic separation component 10 can be first moved into the magnetic separation chamber through the adjustment structure, and then the diamond powder can be added into the magnetic separation box 1 through the feed port, so that the diamond powder can be magnetically separated by the electromagnet 102, so that the magnetic powder in the diamond powder is adsorbed by the electromagnet 102, and the non-magnetic powder falls under the action of gravity and is discharged into the non-magnetic powder collection box 7 through the discharge pipe 16. Subsequently, the electromagnet 102 is driven to move out from the slot by the adjustment structure. When the electromagnet 102 moves to the top of the magnetic powder collection box 8, the electromagnet 102 is powered off, so that the magnetic powder loses its magnetic adsorption and falls into the magnetic powder collection box 8 under the action of gravity. Then, the electromagnet 102 is driven to move from the slot into the magnetic separation box 1 again by the adjustment structure, thereby realizing the magnetic separation of diamond powder.

[0031] When the diamond powder is added into the magnetic separation box 1, the diamond powder falls into the storage area on the dispersion blade 20. Then, the second motor 12 drives the roller 14 to rotate, so that the roller 14 drives the dispersion blade 20 to rotate. At this time, the dispersion blade 20 disperses the diamond powder so that the diamond powder falls evenly, making it easier for the electromagnet 102 to magnetically attract the magnetic powder in the diamond powder, thereby achieving efficient magnetic separation of the diamond powder, avoiding incomplete magnetic separation of the diamond powder, and facilitating uniform magnetic separation of the diamond powder.

[0032] It should be noted that, in order to facilitate the operation of the magnetic separation device, a control box (not shown in the figure) can be installed on the side wall of the front of the magnetic separation box 1.

[0033] Specifically, regarding the above-mentioned regulatory structure, Figure 1-Figure 5 As shown:

[0034] The adjustment structure includes a support frame 5 and a beam 4 fixed between the top of the support frame 5 and the magnetic separation box 1. A cavity is provided inside the beam 4, and a rotatable screw rod 15 is installed in the cavity. The screw rod 15 is connected to a screw rod seat 17 by a threaded engagement. The screw rod seat 17 is in the cavity, and the bottom of the screw rod seat 17 is fixedly connected to the top of the mounting plate 101. A first motor 6 for driving the screw rod 15 to rotate is fixed on one side of the beam 4.

[0035] After the diamond powder is magnetically separated, the first motor 6 can be used to drive the screw 15 to rotate, so that the screw 15 drives the mounting plate 101 to move through the screw seat 17, and then the mounting plate 101 drives the electromagnet 102 to move out of the magnetic separation box 1. When the electromagnet 102 moves to the top of the magnetic powder collection box 8, the power supply of the electromagnet 102 is cut off. At this time, the magnetic powder loses its magnetic adsorption and falls into the magnetic powder collection box 8 under the action of gravity. Then, the first motor 6 drives the screw 15 to rotate in the opposite direction, so that the screw 15 drives the mounting plate 101 to reset through the screw seat 17. At this time, the mounting plate 101 drives the electromagnet 102 to move from the slot into the magnetic separation box 1, and the mounting plate 101 seals the slot to complete the reset of the electromagnet 102, thereby realizing the discharge of the magnetic powder.

[0036] Furthermore, if Figure 1-Figure 5 As shown, two guide rods 11 are fixed between the support frame 5 and the magnetic separation box 1 , and a through hole for the two guide rods 11 to pass through is opened on the top of the mounting plate 101 , and the two guide rods 11 are symmetrically distributed below the beam 4 .

[0037] When the screw seat 17 drives the mounting plate 101 to move, the mounting plate 101 slides along the two guide rods 11, thereby limiting the mounting plate 101 through the guide rods 11, thereby facilitating the stable movement of the mounting plate 101, and further facilitating the stable adjustment of the magnetic separation component 10.

[0038] At the same time, in this embodiment, in order to facilitate the feeding of the magnetic separation box 1, as shown in FIG. Figure 1-Figure 5 As shown, a hopper 2 for storing diamond powder is also provided on the top of the magnetic separation box 1, and an electromagnetic valve 3 is installed between the bottom end of the hopper 2 and the magnetic separation box 1, and the feed port connects the electromagnetic valve 3 with the magnetic separation cavity.

[0039] During the magnetic separation of diamond powder, the diamond powder can be added to the hopper 2, and then the diamond powder in the feed hopper 2 is quantitatively added into the magnetic separation box 1 through the electromagnetic valve 3, and the electromagnetic valve 3 is closed. After the diamond powder in the magnetic separation box 1 is magnetically separated, the electromagnetic valve 3 is opened again, and the diamond powder stored in the hopper 2 is quantitatively added into the magnetic separation box 1 for magnetic separation, and the electromagnetic valve 3 is closed. This reciprocating process is repeated to realize automatic quantitative feeding of the magnetic separation device, which is beneficial to the efficient magnetic separation of diamond powder.

[0040] In addition, in one embodiment, Figure 6 and Figure 7As shown, a plurality of rotatable rotating seats are installed on one side of the mounting plate 101, and a shaft is fixed at one end of each of the plurality of rotating seats, and one end of each of the plurality of shafts extends to the other side of the mounting plate 101, and a synchronous belt 19 is connected between the shaft in the middle and the shafts on both sides thereof. A third motor 18 is also installed on the side wall of the mounting plate 101, and the main shaft of the third motor 18 is connected to the end of the shaft in the middle, and a plurality of electromagnets 102 are respectively installed on the side walls of the plurality of rotating seats.

[0041] When the electromagnet 102 magnetically separates the diamond powder, the rotating seat can be driven to rotate by the third motor 18 and the synchronous belt 19, and then the rotating seat drives the electromagnet 102 to rotate, so that the electromagnet 102 can magnetically attract the magnetic powder material around its outer wall, thereby improving the magnetic attraction effect of the electromagnet 102, avoiding the problem that the magnetic powder material is magnetically attracted to the same position on the electromagnet 102, resulting in weakening of the magnetic force and affecting the adsorption of the magnetic powder material, and can further achieve efficient magnetic separation of diamond powder, avoid incomplete magnetic separation of diamond powder, and be beneficial to improving the magnetic separation effect of diamond powder and facilitating efficient magnetic separation of diamond powder.

[0042] Furthermore, in order to ensure the normal transmission of the synchronous belt 19, the third motor 18 drives the multiple electromagnets 102 to rotate synchronously, such as Figure 1 as well as Figure 3-Figure 5 As shown, an outer cover 13 is installed on one side of the mounting plate 101 , and the outer cover 13 is used to cover and protect the third motor 18 and the synchronous belt 19 .

[0043] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
