DETAILED DESCRIPTION

[0019] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0020] Please refer to Figures 1-4 The utility model provides a technical scheme: a kind of anti-caking quartz sand magnetic separation filtering device, including reaction box 1, reaction groove 2 is set in the inside of reaction box 1, the middle part of reaction groove 2 is fixedly provided with ion exchange membrane 3, two wires 4 are fixedly provided in the inside of one side of reaction box 1, connecting pipeline 5 is fixedly provided in one side of reaction box 1, water pump 6 is fixedly provided at the other end of connecting pipeline 5, the other end of two wires 4 is fixedly connected to the two sides of water pump 6, bottom plate 7 is fixedly provided at the bottom of water pump 6, one end of bottom plate 7 is fixedly connected to the outer surface of one side of reaction box 1, water outlet pipeline 8 is fixedly provided at the top of water pump 6 one end, fluorine ion reaction pool 9 is fixedly connected at the other end of water outlet pipeline 8.

[0021] When specific implementation, quartz sand after magnetic separation screening will enter the inside of reaction box 1 by discharging plate 10 and carry out pickling, reaction box 1 is filled with hydrofluoric acid, when silicon dioxide in quartz sand reacts with hydrofluoric acid, silicon tetrafluoride and water are produced, this reaction removes the impurities and pollution on the surface of quartz sand, so that it becomes more pure. At the same time, due to the generation and volatilization of silicon tetrafluoride gas, part of the pollutants that are difficult to remove are also removed, so that the surface of quartz sand is more dry and clean, and a small amount of silicon in quartz sand and hydrofluoric acid will generate primary cell in closed circuit, so that fluorine ions will gather in the right part of reaction groove 2, and the water pump 6 is powered by the electric quantity generated by primary cell to pump the waste water containing fluorine ions into fluorine ion reaction pool 9, and reacts with sulfuric acid in fluorine ion reaction pool 9 to generate hydrofluoric acid again for repeated use, so as to improve the purity of quartz sand.

[0022] Please refer to Figures 1-4 As shown, discharging plate 10 is fixedly installed on one side of reaction box 1, magnetic separation cylinder 11 is fixedly installed at the other end of discharging plate 10, magnet 12 is fixedly provided on the inner wall of both sides of magnetic separation cylinder 11, power coil 13 is fixedly provided at the bottom center of magnetic separation cylinder 11, discharge port 14 is formed in one side of magnetic separation cylinder 11, the bottom of discharge port 14 abuts against the top surface of discharging plate 10, support 15 is fixedly provided at the bottom of both sides of reaction box 1 and magnetic separation cylinder 11, and base 16 is fixedly connected at the bottom of both supports 15.

[0023] In the implementation, when using the device, first, the energized coil 13 is energized, and the energized coil 13 generates a magnetic field force under the action of the magnet 12. Under the action of the magnetic field force, the magnetic impurities are attracted by the magnet 12, and the non-magnetic quartz sand is discharged from the discharge port 14, so that the preliminary screening of the quartz sand can be realized. However, only magnetic separation cannot screen the weak metal and impurity elements in the quartz sand, which will cause adverse reactions to the quartz sand products.

[0024] In addition, the current direction in the energized coil 13 is perpendicular to the magnetic field line direction of the magnet 12. The current in the energized coil 13 generates a magnetic field force under the action of the magnetic field perpendicular to the current direction, so that the metal impurities in the quartz sand are adsorbed by the magnet 12 under the action of the magnetic field force, and the preliminary screening of the quartz sand is completed.

[0025] In addition, for the acid in the reaction box 1, mixed acid is used, and pickling is an indispensable step for quartz ore purification. Pickling is to use hydrogen ions to react with mineral phases. Compared with single type acid, mixed acid can produce synergistic effect and has high removal rate.

[0026] In addition, since hydrogen fluoride reacts only with most of the quartz sand and impurities, the electrode at the bottom of the lead 4 on the left side of the reaction box 1 is made of aluminum material. Then, the hydrogen fluoride reacts with a small amount of silicon in the quartz sand under the action of the aluminum electrode to generate a primary cell and produce hydrogen gas, and provides power for the water pump 6.

[0027] In addition, the ion exchange membrane 3 is a thin film made of a high molecular material with selective permeability to ions. The ion exchange membrane 3 can isolate the two electrode regions and effectively prevent the substances generated in the two electrode regions from directly contacting, thereby preventing unnecessary chemical reactions. The ion exchange membrane 3 can selectively pass ions and screen according to the charge and properties of the ions. This selective permeability enables the ion exchange membrane 3 to play an important role in balancing the charge and forming a closed loop in the electrochemical process. The ion exchange membrane 3 here concentrates the fluoride ions on the right side of the reaction tank 2, facilitating the removal of fluoride ions.

[0028] Working principle: when using the device, first, the energized coil 13 is energized, and the energized coil 13 generates a magnetic field force under the action of the magnet 12. Under the action of the magnetic field force, the magnetic impurities are attracted by the magnet 12, and the non-magnetic quartz sand is discharged from the discharge port 14, so that the preliminary screening of the quartz sand can be realized. However, only magnetic separation cannot screen the weak metal and impurity elements in the quartz sand, which will cause adverse reactions to the quartz sand products.

[0029] The quartz sand screened by the magnetic separator will enter the inside of the reaction box 1 through the discharging plate 10 to be pickled, and the inside of the reaction box 1 contains hydrofluoric acid. When the silicon dioxide in the quartz sand reacts with the hydrofluoric acid, silicon tetrafluoride and water are generated. This reaction removes the impurities and pollutants on the surface of the quartz sand, making it purer. At the same time, due to the generation and volatilization of silicon tetrafluoride gas, some difficult-to-remove pollutants are also removed, making the surface of the quartz sand drier and cleaner. At the same time, the small amount of silicon in the quartz sand and the hydrofluoric acid will generate a primary cell in the closed circuit, so that the fluoride ions will gather in the right part of the reaction tank 2, and the water pump 6 will be powered by the electricity generated by the primary cell to pump the wastewater containing fluoride ions into the fluoride ion reaction tank 9 to react with the sulfuric acid in the fluoride ion reaction tank 9 to generate hydrofluoric acid again for recycling, thereby improving the purity of the quartz sand.
