[0002] Quartz powder is an important industrial raw material, widely used in photovoltaics, electronics, semiconductors, precision ceramics and special glass. With the continuous improvement of the purity requirements of high-tech industries, more stringent requirements have been put forward for the quality standards of quartz powder. In actual production, quartz powder often contains a certain amount of magnetic impurities, such as hematite, magnetite and other iron oxide impurities, which seriously affect the optical properties, chemical stability and electrical insulation of quartz powder. Therefore, purification of quartz powder is one of the key steps in producing high-purity quartz powder.

[0003] With the development of magnetic separation technology, magnetic separation has gradually become an efficient and environmentally friendly means of purifying quartz powder. The core of magnetic separation is to use the magnetic field to selectively adsorb magnetic impurities and separate the magnetic impurities from quartz powder.

[0004] After searching, a Chinese patent (publication number: CN115193579B) discloses a high-quality quartz sand magnetic separation device, which includes quartz sand magnetic separation equipment, which includes a magnetic separation body, a metal impurity scraping and storing mechanism, a twin-screw material turner, a suspended impurity cleaner, a water circulation mechanism and a quartz sand conveyor. A material guide plate is installed on the right side of the magnetic separation body, the metal impurity scraping and storing mechanism is installed at the upper left corner of the magnetic separation mechanism and the inner side is in contact with the magnetic separation body, the twin-screw material turner is installed at the bottom of the magnetic separation body, the suspended impurity cleaner is divided into two groups and is symmetrically installed on the left and right sides of the magnetic separation body, and the water circulation mechanism includes a water pipe connected to the bottom of the magnetic separation body at one end and a water pump connected to the water pipe.

[0005] In the prior art, when magnetically separating large quantities of quartz materials, the magnetic separation device needs to have a high screening efficiency, and the screened magnetic impurities need to be removed quickly to avoid the problem of reduced magnetic separation performance due to the magnetic impurities covering the magnetic separation part of the magnetic separation device during continuous processing.

[0051] After the two sets of driving mechanisms 3 are started synchronously, the rotating cylinder 4 is driven to rotate inside the supporting seat 1 through the two sets of second connecting parts, while the fixing frame 5 remains stationary relative to the fixing cylinder 2;

[0052] Two groups of extension frames 12 are installed on both sides of the fixed frame 5. Both groups of extension frames 12 extend to one side of the inner wall of the rotating cylinder 4. The area inside the rotating cylinder 4 located below the two groups of extension frames 12 is used as a raw material area for containing the quartz raw material to be magnetically separated.

[0053] A magnetic separation channel 10 is provided on the side of the rotating cylinder 4, and the magnetic separation channel 10 extends to one side of the inner wall of the fixed cylinder 2, and a controllable sealing door assembly is installed inside the magnetic separation channel 10. When the sealing door assembly is closed, the magnetic separation channel 10 is closed, and the inside of the rotating cylinder 4 is converted into a sealed space to prevent the quartz raw material from leaking from the inside of the rotating cylinder 4 during magnetic separation;

[0054] In this embodiment, the sealing door assembly includes a swing unit connected to the magnetic separation channel 10, the swing unit adopts a motor structure, and a plate unit is installed at the output end of the swing unit;

[0056] One side of each magnetic separation element 6 is set as a magnetic separation surface. When the magnetic separation surface faces the inside of the rotating cylinder 4, the magnetic impurities inside the quartz raw material are magnetically separated when passing through the quartz raw material. When the magnetic separation surface faces away from the inside of the rotating cylinder 4, the magnetic impurities are conveniently cleaned;

[0057] After leaving the raw material area, each magnetic separator 6 rotates based on the corresponding flip mechanism 7 to change the magnetic separation surface from a state facing the rotating cylinder 4 to a state facing away from the rotating cylinder 4 , that is, toward the inner wall of the fixed cylinder 2 .

[0058] A discharge plate 11 is installed on the side of the fixed cylinder 2, and one end of the discharge plate 11 abuts against the side of the rotating cylinder 4. When the magnetic separation surface of each magnetic separator 6 passes through the discharge plate 11, the discharge plate 11 discharges the magnetic impurities on the magnetic separation surface of each magnetic separator 6 out of the fixed cylinder 2.

[0059] See also Figure 2 As shown, a feed port is provided on the side of the fixed cylinder 2 facing away from the discharge plate 11, a shielding plate 9 is rotatably connected inside the feed port, and a swing mechanism 8 is installed on at least one side of the fixed cylinder 2, and the output end of the swing mechanism 8 is connected to the shielding plate 9;

When the rotating cylinder 4 rotates, the quartz raw materials are separated, and at the same time, the magnetic separation surfaces in each magnetic separator 6 are started to generate magnetism to adsorb the magnetic impurities in the quartz raw materials. After each magnetic separator 6 leaves the raw material area of ​​the rotating cylinder 4, its corresponding flipping mechanism 7 is started to flip the magnetic separator 6. After the magnetic separator 6 passes the vertex of the rotating cylinder 4, the magnetic separation surface of the magnetic separator 6 stops working and does not generate magnetism. The magnetic impurities corresponding to the outer side of the magnetic separator 6 are separated from the magnetic separator 6 and discharged from the fixed cylinder 2 under the guidance of the discharge plate 11.

[0068] Finally, after the magnetic separator 6 passes through the discharge plate 11, it is driven by the corresponding flip mechanism 7 to flip its magnetic surface again to face the inside of the rotating cylinder 4, and continue to perform magnetic separation on the quartz raw materials in the rotating cylinder 4;

[0069] After completing the magnetic separation, the rotating drum 4 rotates the magnetic separation channel 10 to the upper side of the discharge channel 15 , and finally the sealing door assembly in the magnetic separation channel 10 is opened to discharge the quartz raw material in the rotating drum 4 from the discharge channel 15 .

A magnetic separation device for purifying quartz powder according to claim 1, characterized in that: A plurality of supporting rollers (17) are installed on the outer side of the rotating cylinder (4), and one end of each supporting roller (17) facing away from the rotating cylinder (4) abuts against the inner side of the fixed cylinder (2).
