Description

Technical Field

[0001] The utility model relates to the technical field of quartz sand production devices, in particular to a high-purity quartz sand magnetic separation device. Background Art

[0002] Quartz sand is an important industrial raw material, which is widely used in glass, ceramics, electronics, metallurgy and other industries. However, quartz sand often contains magnetic impurities such as iron and nickel, which seriously affect the purity of quartz sand and thus its application effect.

[0003] In the prior art, after searching, it was found that a Chinese patent disclosed "a magnetic separation device for the production of high-purity quartz sand", and its application number is "202121257277.4". The patent mainly includes a bracket, on which a vertically arranged magnetic separation box is fixedly installed, an input port is arranged at the top of the magnetic separation box, and an output port is arranged at the bottom of the magnetic separation box. Magnetic separation plates are installed in the magnetic separation box, which are arranged cross-spaced from top to bottom. The magnetic separation plates are all installed obliquely in the magnetic separation box, and electromagnets are fixedly installed on the magnetic separation plates. The magnetic field strength of the electromagnets increases from top to bottom; the higher end of the magnetic separation plate is fixedly connected to the inner wall of the magnetic separation box through a support spring, and a support device that cooperates with the lower end of the magnetic separation plate is installed on the magnetic separation box. The support device includes a support tube fixedly installed horizontally on the magnetic separation box and a support rod inserted in the support tube. Although the above-mentioned device can perform multiple magnetic separation treatments on quartz sand by arranging multiple magnetic separation plates in the magnetic separation box, the magnetic separation effect is good and the efficiency is high. However, after the magnetic material on the magnetic separation plate is adsorbed by the electromagnet, as the magnetic separation process continues, the magnetic material gradually accumulates on the magnetic separation plate to form a thick magnetic material layer. The quartz sand is hindered by the magnetic material layer during the flow process, which affects the normal flow of the quartz sand, causing the flow speed to slow down or even stagnate, thereby reducing the magnetic separation efficiency; and when cleaning the magnetic material on the magnetic separation plate, the device usually needs to be shut down for cleaning, which is not only time-consuming and labor-intensive, but also reduces the production efficiency of the magnetic separation device. Therefore, the utility model provides a high-purity quartz sand magnetic separation device to solve the problems raised in the above background technology. Summary of the invention

The sand material falls freely due to the rotation of the drum 3 and gravity, and the bottom of the permanent magnet 6 extends to one side of the bottom of the drum 3. After the magnetic material rotates with the drum 3 to the tail end of the permanent magnet 6, it loses the action of the permanent magnet 6 and can fall freely to complete the separation operation with the drum 3, thereby ensuring the continuity and stability of the magnetic separation process; and two drums 3 and permanent magnets 6 are set for magnetic separation, so that the magnetic material separation effect is better, thereby ensuring the quality of the magnetic separation of the sand material, and being conducive to better improving the purity of the high-purity quartz sand material.

[0026] A first material dividing plate 8 and a second material dividing plate 9 are fixedly connected inside the box body 1 and below the two rollers 3. The first material dividing plate 8 can guide the magnetic material and the sand material screened for the first time to the second magnetic material outlet 12 and the side of the lower roller 3 respectively. Under the action of the second material dividing plate 9, the sand material after magnetic separation and the magnetic material of the second magnetic separation can be guided to the sand material outlet 10 and the first magnetic material outlet 11 respectively. A second magnetic material outlet 12 is provided on one side of the box body 1. The inside of the box body 1 and the bottom of the first material dividing plate 8 and the second magnetic material outlet 1 2 is fixedly connected with a guide plate 13, and the guide plate 13 is inclined to facilitate the discharge of the magnetic material screened out for the first time to the outside of the box body 1 through the second magnetic material outlet 12.

[0027] The driving assembly includes a motor 16 fixedly connected to the outside of the box body 1 and two pulleys 17 connected by belt transmission. The two pulleys 17 are respectively fixedly connected to the rotating shaft 2 and the output shaft of the motor 16. The operation of the motor 16 drives the pulley 17 to rotate.

The rollers 3 rotating towards each other can respectively drive the magnetic materials adsorbed on the two rollers 3 to move to the second magnetic material outlet 12 and the first magnetic material outlet 11.
