Description

Technical Field

[0001] This utility model relates to the field of sand making equipment technology, and more specifically, to a high-efficiency magnetic separation device in the quartz sand beneficiation process. Background Technology

[0002] Quartz sand, as an important industrial raw material, has wide applications in many fields such as glass, ceramics, and electronics. To meet the stringent purity requirements of different industries, magnetic separation during mineral processing is crucial. Traditional magnetic separation devices are mostly designed based on a single magnetic field strength and a fixed magnetic system structure. While they can remove some magnetic impurities when processing quartz sand, they struggle to achieve precise separation when dealing with impurities of varying magnetic properties, particle sizes, and distributions. Furthermore, traditional devices are prone to decreased magnetic separation efficiency and incomplete impurity removal when processing large volumes, affecting the quality of the final product.

[0003] However, in actual screening processes, due to the complexity of impurities in quartz sand, some impurities, as well as those with similar particle sizes to quartz sand, remain mixed in and are difficult to separate effectively. This results in the quartz sand not meeting the purity standard after one magnetic separation, requiring repeated screening. Repeated screening not only consumes a significant amount of time and extends the production cycle but also consumes additional energy, increasing production costs and reducing the efficiency and economy of the entire quartz sand beneficiation process.

[0004] Therefore, we have made improvements to this and proposed a high-efficiency magnetic separation device for the quartz sand beneficiation process. Utility Model Content

[0005] In order to achieve the above-mentioned objectives, this utility model provides a high-efficiency magnetic separation device in the quartz sand beneficiation process to improve the above-mentioned problems.

[0006] The application is as follows:

[0007] include:

[0008] support;

[0009] A magnetic wheel, disposed on one side of the bracket, has its diameter gradually narrowing from both ends towards the center, and has the following characteristics:

[0010] A drive source, mounted on the bracket, drives the magnetic wheel to rotate about its own axis;

[0011] A fixing column is disposed in the middle of the magnetic wheel and is coaxially arranged with the magnetic wheel;

[0012] A cam is mounted on the fixed post and extends to a radial length greater than that of the two magnetic wheels on both sides;

[0013] The conveyor belt, mounted on the magnetic wheel and driven by the magnetic wheels at both ends of the support, has the following characteristics:

[0014] An inclined surface is formed on the conveyor belt, with the same inclination trend as the cross-sectional edge of the magnetic wheel, forming a concave surface that facilitates the quartz sand to move towards the centerline;

[0015] The receiving rollers are evenly distributed on the support and receive the non-contact surface of the conveyor belt;

[0016] When the quartz sand reaches the vicinity of the magnetic wheel on the conveyor belt, the cam lifts the middle of the conveyor belt and causes the inclined surface to change from a concave surface to a convex surface.

[0017] Preferably, the radial length of the fixed column is less than the radial length of both sides of the magnetic wheel.

[0018] Preferably, the axis of the receiving roller is parallel to the direction of inclination of the inclined plane.

[0019] Preferably, the magnetic wheel further includes:

[0020] Friction grooves are formed on both circumferential surfaces of the magnetic wheel;

[0021] The conveyor belt also includes:

[0022] Friction pads are evenly arranged on the contact path between the conveyor belt and the friction groove, and the spacing is half the groove spacing of the friction groove.

[0023] Preferably, the distance between two adjacent receiving rollers is greater than the axial length of the fixed column.

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] In the scheme of this application:

[0026] To address the problem of insufficient dispersion of magnetic impurities due to encapsulation and excessively high costs caused by repeated magnetic separation processes in the existing quartz sand beneficiation process, this application utilizes components such as a support, magnetic wheel, conveyor belt, and cam. The cam lifts the middle of the conveyor belt, causing the material to roll and disperse. The inclined surface cooperates with the magnetic wheel to form an initial concave surface, reducing the detachment of quartz sand. The friction groove meshes with the friction plate to increase friction, prevent slippage, and generate wave-like intervals to further disperse the material. This achieves secondary and thorough dispersion of the material, exposes internal impurities, and effectively adsorbs them by the magnetic wheel, thereby efficiently completing magnetic separation, reducing losses, and avoiding repeated operations.

[0033] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0034] For an example, please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 A high-efficiency magnetic separation device for quartz sand beneficiation process, comprising:

[0035] Bracket 1;

[0036] Magnetic wheel 2 is disposed on one side of bracket 1, and its diameter gradually narrows from both ends towards the middle, having the following characteristics:

[0037] The drive source is mounted on the bracket 1 to drive the magnetic wheel 2 to rotate around its own axis;

[0038] A fixed column 22 is disposed in the middle of the magnetic wheel 2 and is coaxially arranged with the magnetic wheel 2;

[0039] Cam 23 is mounted on fixed post 22 and extends to a radial length greater than that of the two magnetic wheels 2 on both sides;

[0040] The conveyor belt 3, mounted on the magnetic wheel 2, is driven by the magnetic wheels 2 at both ends of the bracket 1 and has the following characteristics:

[0041] Inclined surface 31 is formed on the conveyor belt 3 and has the same inclination trend as the cross-sectional edge of the magnetic wheel 2, forming a concave surface that facilitates the quartz sand to move closer to the center line.

[0042] The receiving roller 4 is evenly distributed on the support 1 and receives the non-contact surface of the conveyor belt 3;

[0043] When the quartz sand reaches the conveyor belt 3 and then the adjacent magnetic wheel 2, the cam 23 lifts the middle of the conveyor belt 3 and causes the inclined surface 31 to change from a concave surface to a convex surface;

[0044] The working principle of the magnetic separation device is that the magnetic wheel 2 drives the conveyor belt 3 to rotate, so that the magnetic impurities adhere to the surface of the conveyor belt 3 through the magnetic force. When the impurities move away from the magnetic wheel 2 on the conveyor belt 3, the magnetic effect weakens or even disappears, resulting in a weakening of the magnetic attraction effect. Then, the impurities that can be magnetically attracted fall under the action of gravity, thus producing a separation effect.

[0045] The problem this device solves is that impurities that can be magnetically separated are encapsulated by quartz sand, resulting in insufficient dispersion. This requires repeated magnetic separation processes, leading to excessively high costs. This device mainly uses a concave conveyor belt 3 and a magnetic wheel 2 to reduce the loss of quartz sand during transportation, i.e., to prevent it from falling off the conveyor belt 3.

[0046] When the quartz sand and impurities on the conveyor belt 3 move together to a position close to the magnetic wheel 2, the cam 23 lifts the middle position of the conveyor belt 3. Since the main material is in the middle position, this lifting change will cause the material to disperse to both sides, resulting in a rolling effect and movement on the conveyor belt 3. This causes the material to be dispersed a second time, exposing the internal impurities and allowing the magnetic wheel 2 to attract them.

[0047] At the same time, due to the action of the friction groove 21 and the friction plate 32, on the one hand, the friction between the magnetic wheel 2 and the conveyor belt 3 can be increased to prevent the belt from slipping. On the other hand, since the spacing of the friction plate 32 is only half that of the friction groove 21, part of the friction plate 32 engages with the friction groove 21, while part of it is in contact with the circumferential surface of the magnetic wheel 2. This causes the wavy spacing to appear on the circumference of the conveyor belt 3, which further disperses the raw material and separates the material. Ultimately, the material is completely dispersed and then adsorbed by the magnetic wheel 2.

[0048] The radial length of the fixed column 22 is less than the radial length of both sides of the magnetic wheel 2, so that a cavity is created between the fixed column 22 and the magnetic wheel 2 for the inclined surface 31 of the conveyor belt 3 to accommodate.

[0049] The axis of the receiving roller 4 is parallel to the inclination direction of the inclined plane 31.

[0050] Magnetic wheel 2 also includes:

[0051] Friction grooves 21 are formed on both circumferential surfaces of the magnetic wheel 2;

[0052] Conveyor belt 3 also includes:

[0053] Friction plates 32 are evenly arranged on the contact path between the conveyor belt 3 and the friction groove 21, and the interval is half of the groove interval of the friction groove 21.

[0054] The distance between two adjacent receiving rollers 4 is greater than the axial length of the fixed column 22, which allows the receiving rollers 4 to better support the conveyor belt 3.

[0055] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
