Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to a quartz sand magnetic separation device with a cleaning mechanism. Background Technology

[0002] Quartz sand is an important industrial mineral raw material, widely used in glass, ceramics, casting, electronics and other industries. High-quality quartz sand requires extremely low iron impurity content. Magnetic separation is one of the most common and effective methods for removing ferromagnetic impurities from quartz sand. A quartz sand magnetic separator is a device used to remove ferromagnetic impurities from quartz sand. Its main function is to remove ferromagnetic impurities from quartz sand through the magnetic separation process to improve the purity of quartz sand.

[0003] Currently, traditional magnetic separators suffer from the problem that impurities easily adhere to the surface of the magnetic rollers, leading to a decrease in sorting efficiency. This necessitates machine shutdown and manual cleaning, which impacts production efficiency. To address this issue, we propose a quartz sand magnetic separator with a cleaning mechanism.

The feeding assembly 8 has an auxiliary feeding roller 801 with a surface covered with anti-slip silicone or polyurethane to ensure uniform feeding of quartz sand, avoid accumulation or blockage, and improve sorting efficiency.

[0025] The working principle of this utility model is as follows:

[0026] When using the equipment, the user first starts the equipment through the control box 9. Quartz sand is evenly fed into the main body box 2 through the auxiliary feeding roller 801 in the feeding assembly 8. Then, the magnetic separation drum 3 rotates under the drive of the power box 301. Its built-in permanent magnet adsorbs ferromagnetic impurities. The pure quartz sand is discharged from the discharge port 201 through the inclined plate 202. The scraper 7 is fixed to the slot 701 of the crossbeam 5 through the locking block 702, and continuously scrapes off the impurities adsorbed on the surface of the magnetic separation drum 3. At the same time, the high-pressure air nozzle 606 of the blowing assembly 6 sprays high-pressure airflow under the action of the high-pressure blower 601, which, together with the scraper 7, thoroughly cleans the magnetic separation drum 3. After that, the cleaned impurities fall into the collection box 4. Finally, the protective door 203 can be opened to remove the collection box 4 to clean the impurities. The whole process realizes continuous magnetic separation of quartz sand and automatic drum cleaning.
