Description

Technical Field

[0001] This utility model relates to the field of fused silica sand technology, specifically a magnetic separator for fused silica sand production. Background Technology

[0002] Quartz sand is a hard, wear-resistant, and chemically stable silicate mineral. It is an important industrial mineral raw material, widely used in glass, casting, ceramics and refractory materials, ferrosilicon smelting, metallurgical flux, metallurgy, construction, chemicals, plastics, rubber, abrasives, and other industries. However, in existing technologies, the elemental and fluid impurities present in quartz products made from melted quartz sand significantly affect their quality.

[0003] Fused silica is an amorphous (glassy) form of silicon dioxide (quartz, silica). It is a typical glass with a long-range disordered atomic structure. Its high operating temperature and low coefficient of thermal expansion are provided by its three-dimensional cross-linked structure. Fused silica has a melting temperature of approximately 1713℃, low thermal conductivity, and one of the lowest coefficients of thermal expansion among all refractory materials, resulting in extremely high thermal shock resistance. Therefore, fused silica shells rarely crack due to drastic temperature changes during firing and casting, making it an ideal refractory material for investment casting. It can be used as a face or back coating, as well as a sand-spreading material. Fused silica partially or completely improves the performance of the shell. The low coefficient of thermal expansion of fused silica helps prevent cracking and deformation of the shell during dewaxing and firing, ensuring dimensional stability of the casting. The high purity of fused silica results in good coating stability and improves the high-temperature creep resistance of the shell.

[0004] Currently, magnetic separators are commonly used for the separation of fused silica sand. However, existing magnetic separators typically use fixed permanent magnets to provide magnetic force, making it difficult to adjust the magnetic field to handle different separation levels. This limits the versatility of a single magnetic separator to a single level of separation. Therefore, this paper proposes a magnetic separator for fused silica sand production.

[0028] Further improvements include annularly distributed feeding grooves 13 on the circumferential surface of the feeding roller 10, with an adjusting block 14 embedded inside the feeding groove 13. The adjusting block 14 is fastened to the feeding groove 13. By providing the feeding grooves 13 on the circumferential surface of the feeding roller 10, the molten quartz sand is quantitatively fed into the magnetic separator 2 during the rotation of the feeding roller 10, facilitating material separation by the magnetic separator 3. The adjusting block 14 embedded inside the feeding groove 13 allows for easy adjustment of the volume within the feeding groove 13, enabling adjustment of the feeding amount according to actual production and processing needs, thus improving ease of use and flexibility.

[0029] Further improvements include an outwardly protruding snap-fit ​​edge 15 at the lower edge of the adjusting block 14, and a snap-fit ​​groove 16 on the inner wall of the feeding trough 13. The snap-fit ​​edge 15 and the snap-fit ​​groove 16 are interlocked and connected. The adjusting block 14 is integrally injection molded from engineering plastic.

Moreover, the integrally injection molded adjusting block 14 is easier to process, effectively reducing production costs.

[0030] Further improvements include mounting holes 17 on the surface of the fixed plate 4, with fixing bolts 18 inside the mounting holes 17 for fixing the geared motor 7 and the feeding motor 8. By providing mounting holes 17 on the surface of the fixed plate 4, it is convenient to use the fixing bolts 18 to fix the geared motor 7 and the feeding motor 8, thereby improving the structural strength of the connection between the geared motor 7, the feeding motor 8 and the fixed frame 1, and improving the stability of the magnetic separator operation.

[0031] In a further improvement, an inner liner 19 is embedded inside the magnetic separator 3. Several mounting grooves 20 are fixed on the surface of the inner liner 19. Permanent magnets 5 and counterweights 6 are embedded inside the mounting grooves 20. By fixing the inner liner 19 inside the magnetic separator 3 and using the mounting grooves 20 on the surface of the inner liner 19, it is convenient to adjust the number of permanent magnets 5 according to the usage requirements. At the same time, it is convenient to perform dynamic balancing and improve the rotational stability of the magnetic separator 3.

[0032] Further improvements include an inner liner frame 19 consisting of a connecting shaft 21 and several connecting plates 22. The connecting plates 22 are radially and evenly distributed on the surface of the connecting shaft 21. A support seat 23 is provided at the connection point between the end of the connecting shaft 21 and the fixed frame 1. The connecting shaft 21 and the support seat 23 are rotatably connected. By providing radially distributed connecting plates 22 on the surface of the connecting shaft 21, the stability of the connection between the central shaft and the magnetic separator is improved. By providing a support seat 23 at the connection point between the connecting shaft 21 and the fixed frame 1, the stability of the connection between the magnetic separator roller 3 and the fixed frame 1 is improved.

[0033] Further improvements include a snap-fit ​​groove 24 on one side of the counterweight 6 and a connecting buckle 25 fixedly connected to the other side of the counterweight 6.

[0034] Specifically, the inner wall of the mounting groove 20 is provided with a positioning strip 26, the side wall of the positioning strip 26 is provided with a sliding groove 27, and a support spring piece 28 is provided at the connection between the positioning strip 26 and the mounting groove 20.

By providing a support spring piece 28 with a positioning strip 26 on the inner wall of the mounting groove 20, it is convenient to press and fix the permanent magnet 5 and the counterweight 6 embedded in the mounting groove 20, thereby improving the stability of the installation.

[0035] In operation, the crushed molten silica sand is poured into the hopper 9. The feeding motor 8 drives the feeding roller 10 to rotate, and the molten silica sand deposited in the feeding trough 13 is fed downward into the magnetic separator 2. The reduction motor 7 drives the magnetic separator 3 to rotate, and the molten silica sand is sorted. Different molten silica sand raw materials are discharged through the discharge port 11 and the waste port 12. When adjusting the magnetic force of the magnetic separator 3, permanent magnets 5 of different numbers and positions are installed in the mounting groove 20 inside the magnetic separator 3, and corresponding counterweights 6 are installed to adjust the dynamic balance of the magnetic separator 3.

[0036] The problem solved by this invention is that existing magnetic separators mostly use fixed permanent magnets to provide magnetic force, which makes it difficult to adjust the magnetism when facing different levels of sorting work. This results in a single magnetic separator being able to complete only one level of sorting work, reducing the versatility of the magnetic separator. This invention provides an inner liner 19, permanent magnets 5, and a counterweight 6 inside the magnetic separator roller 3. This allows for easy adjustment of the number and position of the permanent magnets 5 inside the magnetic separator roller 3, making it easy to adjust the magnetic force of the magnetic separator roller 3 according to the needs of production and processing. In conjunction with the adjustable counterweight 6, it is convenient to adjust the dynamic balance of the rotation of the magnetic separator roller 3, thereby improving the stability of the rotation of the magnetic separator roller 3.
