Abstract
Description
Technical Field
[0001] This utility model relates to the field of magnetic separator technology, and in particular to a plate magnetic separator for removing impurities from mineral sands. Background Technology
[0002] Magnetic separators are widely used separation equipment in industries such as mining, metallurgy, and environmental protection. They are favored for their high efficiency and economy. This type of machine mainly uses the magnetic differences between substances to achieve separation. It can separate magnetic minerals, such as iron ore and rare earth minerals, from mixtures while removing non-magnetic impurities. This technology not only improves the purity of minerals and reduces subsequent processing costs, but also plays an important role in the extraction of renewable resources and environmental protection. In modern industrial production, the application of magnetic separators is not limited to mineral separation, but has also been extended to fields such as waste treatment and soil remediation. For example, in the process of coal ash treatment in power plants, magnetic separators can effectively remove sintered magnetic materials, thereby improving the efficiency and environmental protection effect of subsequent treatment.
[0003] During the processing of mineral sands, impurities need to be removed, and magnetic separation is one of the key steps. Currently, the commonly used magnetic separator is the plate-type magnetic separator, which has high working efficiency and huge processing capacity in impurity removal and screening. For example, Chinese Patent Publication No. CN220258331 U discloses "a plate-type magnetic separator for removing impurities from quartz sand". The lifting column slides inside the bottom column to adjust the length of the support legs. By adjusting the length of the four support legs, the tilt angle of the conveyor frame can be adjusted, which increases the range of use of the magnetic separator and improves its flexibility.
[0004] However, in actual use, magnetic separators usually separate mineral slurries. The magnetic minerals separated tend to adhere to the conveyor belt and drip into the non-magnetic mineral area as the conveyor belt rotates. This reduces the purity of the non-magnetic minerals, affecting subsequent processing and purification, and also reduces the yield of magnetic minerals. Utility Model Content
[0005] The purpose of this invention is to address the shortcomings of existing technologies, such as magnetic minerals easily adhering to the conveyor belt after magnetic separation and dripping into the non-magnetic mineral area as the conveyor belt rotates, leading to a decrease in the purity of non-magnetic minerals and a decrease in the yield of magnetic minerals. Therefore, this invention proposes a plate-type magnetic separator for removing impurities from mineral sands.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] Design a plate magnetic separator for ore sand impurity removal and beneficiation, including a machine body, a feed inlet on the machine body, a crushing component that cooperates with the feed inlet inside the machine body, a magnetic separation component that cooperates with the crushing component inside the machine body, and a discharge outlet and a waste outlet on the machine body;
[0008] The magnetic separation assembly includes a conveyor belt and a magnetic plate. The magnetic plate is inserted into the conveyor belt, and one end of the magnetic plate passes through the machine body and is fixedly connected to a mounting plate.
[0009] Furthermore, the machine body is provided with two guide plates, which correspond to the discharge port and the waste port, respectively.
[0010] Furthermore, the conveyor belt includes a power roller, a passive roller, and a belt body. The machine body is equipped with a motor that is powered and connected to the power roller, and the machine body is equipped with a cleaning component that cooperates with the belt body.
[0011] Furthermore, the cleaning component includes a brush and a scraper disposed within the body of the machine and cooperating with the belt body. A rotating shaft that is rotatably connected to the brush is fixedly disposed within the body of the machine, and a drive mechanism that is poweredly connected to the brush is disposed within the body of the machine.
[0012] Furthermore, the driving mechanism includes a cam rotatably disposed within the machine body, a driving rod eccentrically disposed on the cam, and a driving groove provided on the brush for movably engaging with the driving rod.
[0013] Furthermore, both the cam and the conveyor belt are equipped with pulleys, and the two pulleys are connected by a belt. The machine body is equipped with a tensioning structure that cooperates with the belt.
[0014] The beneficial effects of the plate magnetic separator for removing impurities from mineral sand proposed in this utility model are as follows:
[0015] In this invention, a crushing component is used to process and crush the slurry, thereby crushing large-volume mineral sands in the slurry to prevent the mineral sands from being too large and heavy to be magnetically separated, thus affecting the purity of non-magnetic minerals.
[0016] Secondly, in this invention, the cleaning component works in conjunction with the driving mechanism to drive the brush to swing back and forth to clean the conveyor belt, sweeping off the magnetic minerals attached to its surface, preventing the magnetic minerals from dripping into the non-magnetic area, improving the purity of the non-magnetic minerals, and at the same time increasing the output of the magnetic minerals.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0024] Reference Figure 1-5 A plate magnetic separator for removing impurities from mineral sand includes a body 1, a feed inlet 2 on the body 1, a crushing component 3 that cooperates with the feed inlet 2 inside the body 1, a magnetic separation component 4 that cooperates with the crushing component 3 inside the body 1, a discharge outlet 5 and a waste outlet 6 on the body 1.
[0025] The magnetic separation assembly 4 includes a conveyor belt 41 and a magnetic plate 42. The magnetic plate 42 is inserted into the conveyor belt 41, and one end of the magnetic plate 42 passes through the machine body 1 and is fixedly connected to the mounting plate 43.
[0026] In this invention, the crushing component 3 processes and crushes the slurry fed into the feed inlet 2, breaking down large-volume mineral sands in the slurry to prevent them from being too large and heavy to be magnetically separated, thus affecting the purity of non-magnetic minerals. Simultaneously, the magnetic plate 42 can be removed for easy maintenance and upgrades.
[0027] Furthermore, in this embodiment, two guide plates 7 are provided inside the machine body 1. The two guide plates 7 correspond to the discharge port 5 and the waste port 6, respectively. The magnetic mineral slurry and the non-magnetic mineral slurry are guided by the two guide plates 7 to prevent them from mixing and affecting the purity.
[0028] Furthermore, in this embodiment, the conveyor belt 41 includes a power roller 411, a passive roller 412, and a belt body 413. The machine body 1 is equipped with a motor 414 that is poweredly connected to the power roller 411. The machine body 1 is equipped with a cleaning component 8 that cooperates with the belt body 413. The power roller 411 is driven to rotate by the motor 414, and the power roller 411 drives the belt body 413 and the passive roller 412 to rotate. The cleaning component 8 cleans the belt body 413 to remove the attached slurry.
[0029] It should be noted that, in this embodiment, the cleaning component 8 includes a brush 81 and a scraper 82 disposed inside the body 1 and cooperating with the belt 413. A rotating shaft that is rotatably connected to the brush 81 is fixedly disposed inside the body 1. A drive mechanism 9 that is poweredly connected to the brush 81 is disposed inside the body 1. The brush 81 is driven by the drive mechanism 9 to reciprocate around the rotating shaft, thereby improving the cleaning effect on the belt 413.
[0030] Furthermore, in this embodiment, the drive mechanism 9 includes a cam 91 rotatably disposed within the body 1. A drive rod 92 is eccentrically disposed on the cam 91, and a drive groove 93 is provided on the brush 81 that is movably inserted into the drive rod 92. When the cam 91 rotates, the drive rod 92 rotates along with it, forming a circular trajectory, and drives the drive groove 93, causing the brush 81 to reciprocate.
[0031] More specifically, in this embodiment, both the cam 91 and the conveyor belt 41 are equipped with pulleys 94, and the two pulleys 94 are connected by a belt 95. The machine body 1 is equipped with a tensioning structure that cooperates with the belt 95. When the conveyor belt 41 is working, it drives the pulleys 94 to rotate, thereby driving the brush 81 to swing and clean, which is more synchronized. At the same time, it avoids the need to set up an additional motor to drive the brush 81 to swing, thus reducing the power consumption of the magnetic separator.
[0032] Working method: During operation, the slurry input from the feed inlet 2 is processed and crushed by the crushing component 3, and the large volume mineral sand in the slurry is crushed. The mineral sand slurry is magnetically separated by the conveyor belt 41 and the magnetic plate 42, and the non-magnetic mineral slurry and the magnetic mineral slurry are discharged along the discharge outlet 5 and the waste outlet 6, respectively.
[0033] The motor 414 drives the power roller 411 to rotate, which in turn drives the belt body 413 and the passive roller 412 to rotate. When the conveyor belt 41 is working, it drives the pulley 94 and the belt 95 to rotate, drives the cam 91 to rotate, and the drive rod 92 rotates to form a circular trajectory, which drives the drive groove 93, causing the brush 81 to swing back and forth to clean the belt body 413.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
