Technical Field

[0001] This utility model relates to the field of magnetic separator technology, and in particular to a high gradient magnetic separator for quartz sand. Background Technology

[0002] The high gradient magnetic separator for quartz sand is a wet magnetic separation device based on the principle of high gradient magnetic field. It is designed to remove weakly magnetic iron impurities (such as hematite and limonite) of fine particle size (<0.1mm) from quartz sand.

[0003] However, existing high-gradient magnetic separators for quartz sand often lack a circulating cooling structure for the magnetic separator tubes, which makes the magnetic separator tubes prone to overheating and affecting the operation of the equipment.

[0004] Therefore, it is necessary to provide a high gradient magnetic separator for quartz sand to solve the above-mentioned technical problems. Utility Model Content

[0013] Compared with related technologies, the high gradient magnetic separator for quartz sand provided by this utility model has the following beneficial effects: This invention provides a high-gradient magnetic separator for quartz sand. An excitation coil and steel wool create a high-intensity magnetic field and a local gradient formed by the magnetic medium within the magnetic separator tube. The slurry is introduced into the magnetic separator tube through the feed pipe. Magnetic impurities are captured by the magnetic separator tube and steel wool, while pure quartz sand is discharged along the discharge pipe with the water flow. A forward and reverse washing mechanism washes the inner wall of the magnetic separator tube and the steel wool in both directions. A circulating cooling mechanism circulates and cools the magnetic separator tube, preventing overheating and ensuring stable operation. Water is introduced into a booster pump through the inlet pipe, pressurizing the water flow. The pressurized water then flows through a guide pipe, an inlet tee, and an inlet diversion pipe into the magnetic separator tube, washing the inner wall and steel wool, thus removing impurities and forming tailings that flow through the outlet pipe and outlet water flow. The three-way pipe and drain pipe discharge the oil. By controlling the opening and closing of the first and second diagonal solenoid valves, the inner wall of the magnetic separator and the steel wool can be flushed in both directions. The heat transfer oil in the housing is extracted by the oil pump and injected into the heat transfer copper pipe. The heat in the heat transfer oil is conducted to the heat dissipation fins through the heat transfer copper pipe. The airflow generated by the fan can dissipate heat from the heat transfer fins. The cooled heat transfer oil flows back into the housing along the heat transfer copper pipe, thereby cooling the heat transfer oil in the housing. The cooled heat transfer oil can circulate and cool the magnetic separator. Heat transfer oil can be injected into the housing through the oil inlet and sealed by the sealing cap. The heat transfer oil in the housing and the heat transfer copper pipe can be discharged through the oil drain pipe and oil drain valve. The oil temperature sensor can monitor the oil temperature in the housing. The controller controls the start and stop of the fan and oil pump according to the oil temperature.

The heat in the heat-conducting oil is conducted to the heat dissipation fins 20 through the heat-conducting copper pipe 22. The airflow generated by the fan 21 can dissipate heat from the heat dissipation fins 20. The cooled heat-conducting oil flows back to the housing 3 along the heat-conducting copper pipe 22, thereby cooling the heat-conducting oil in the housing 3.

[0024] The working principle of the high gradient magnetic separator for quartz sand provided by this utility model is as follows: Open the two material valves 7 and close the two first solenoid valves 15 and the two second solenoid valves 17. The excitation coil 8 and the steel wool 9 can form a high-intensity magnetic field and a local gradient formed by the magnetic medium in the magnetic separation tube 4. The slurry can be introduced into the magnetic separation tube 4 through the feed pipe 5. The magnetic separation tube 4 and the steel wool 9 can capture magnetic impurities. The pure quartz sand is discharged along the discharge pipe 6 with the water flow. During operation, the heat-conducting oil in the housing 3 is drawn out by the oil pump 23 and injected into the heat-conducting copper pipe 22. The heat in the heat-conducting oil is conducted to the heat dissipation fins 20 through the heat-conducting copper pipe 22. The airflow generated by the fan 21 can dissipate heat from the heat dissipation fins 20. The cooled heat-conducting oil flows back to the housing 3 along the heat-conducting copper pipe 22, thereby cooling the heat-conducting oil in the housing 3. The cooled heat-conducting oil can circulate and cool the magnetic separator 4. The oil temperature sensor 29 can monitor the oil temperature in the housing 3. The controller 28 controls the start and stop of the fan 21 and the oil pump 23 according to the oil temperature. When it is necessary to perform forward and reverse rinsing on the inner wall of the magnetic separator 4 and the steel wool 9, close the two material valves 7 and open the first solenoid valve 15 and the second solenoid valve 17 diagonally opposite each other. Water is introduced into the booster pump 10 through the water inlet pipe 11. The booster pump 10 pressurizes the water flow. The pressurized water flow enters the magnetic separator 4 through the water guide pipe 12, the water inlet tee pipe 13 and the water inlet diversion pipe 14, thereby rinsing the inner wall of the magnetic separator 4 and the steel wool 9, thereby stripping impurities from the magnetic separator 4 and the steel wool 9, forming tailings that are discharged through the water outlet pipe 16, the water outlet tee pipe 18 and the drain pipe 19. By controlling the opening and closing of the first solenoid valve 15 and the second solenoid valve 17 diagonally opposite each other, the inner wall of the magnetic separator 4 and the steel wool 9 can be rinsed in both directions.

[0025] Compared with related technologies, the high gradient magnetic separator for quartz sand provided by this utility model has the following beneficial effects: This invention provides a high-gradient magnetic separator for quartz sand. An excitation coil 8 and steel wool 9 create a high-intensity magnetic field and a local gradient formed by the magnetic medium within the magnetic separator tube 4. The slurry is introduced into the magnetic separator tube 4 through the feed pipe 5. Magnetic impurities are captured by the magnetic separator tube 4 and the steel wool 9. Pure quartz sand is discharged along the discharge pipe 6 with the water flow. A forward and reverse washing mechanism washes the inner wall of the magnetic separator tube 4 and the steel wool 9 in both directions. A circulating heat dissipation mechanism further cools the magnetic separator tube 4. Circulating cooling is performed to prevent overheating of the magnetic separator 4 from affecting the stable operation of the equipment. Water is introduced into the booster pump 10 through the water inlet pipe 11. The booster pump 10 pressurizes the water flow, and the pressurized water flows into the magnetic separator 4 through the water guide pipe 12, the water inlet tee pipe 13, and the water inlet diversion pipe 14, thereby washing the inner wall of the magnetic separator 4 and the steel wool 9, thus removing impurities from the magnetic separator 4 and the steel wool 9, forming tailings that flow through the water outlet pipe 16, the water outlet tee pipe 18, and the drainage pipe 1. The discharge of oil 9, by controlling the opening and closing of the first solenoid valve 15 and the second solenoid valve 17 diagonally opposite each other, allows for forward and reverse flushing of the inner wall of the magnetic separator 4 and the steel wool 9. The oil pump 23 extracts the heat-conducting oil from the housing 3 and injects it into the heat-conducting copper pipe 22. The heat in the oil is then transferred to the heat dissipation fins 20 via the copper pipe 22. The airflow generated by the fan 21 dissipates heat from the heat dissipation fins 20. The cooled oil then flows back into the housing 3 along the copper pipe 22, thus cooling the housing. The heat transfer oil inside the body 3 is cooled down, and the cooled heat transfer oil can circulate and cool the magnetic separator 4. Heat transfer oil can be injected into the body 3 through the oil inlet 24. The oil inlet 24 can be sealed through the sealing cap 25.
