[0002] With the rapid development of high-tech industries such as semiconductors, photovoltaics, and optical communications, the demand for high-purity quartz sand (SiO2 content > 99.9%, total impurities < 1000 ppm) as a key basic material is continuously increasing, as are the purity requirements. The content of ferromagnetic impurities (such as magnetite and hematite) in quartz sand directly affects the performance of end products. For example, in the semiconductor field, iron impurities can lead to an increase in the defect rate of silicon wafers; in the photovoltaic field, iron impurities can reduce the light transmittance and high-temperature resistance of quartz crucibles.

[0003] Traditional magnetic separators use a single-stage gear reducer and conveyor belt drive. After long-term use, the conveyor belt may loosen, affecting normal transmission. Therefore, a magnetic separation device for high-purity quartz sand production has been proposed to solve the above problems. Utility Model Content

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] In the embodiments, by Figure 1-3 A magnetic separation device for producing high-purity quartz sand is provided, comprising a magnetic separation support 1, four rotating seats 2 fixedly connected to the magnetic separation support 1, a rotating shaft 3 rotatably connected between two adjacent rotating seats 2 on the left and right sides, pulleys 4 fixedly connected to the outer sides of the two rotating shafts 3, the two pulleys 4 being connected by a belt 5, a support mechanism 6 for supporting the belt 5 provided on the magnetic separation support 1, an adjustment mechanism 7 for adjusting the tension of the belt 5 provided on the magnetic separation support 1, a support frame 8 fixedly connected to the magnetic separation support 1, a drive mechanism 9 for driving the right rotating shaft 3 to rotate provided on the support frame 8, and a magnetic separation plate 10 located above the belt 5 fixedly connected to the left end of the support frame 8.

[0023] With the above settings, the drive mechanism 9 drives the right rotating shaft 3 to rotate. Through the linkage of the pulley 4 and the belt 5, the left rotating shaft 3 rotates synchronously, forming the cyclic motion of the belt 5. The quartz sand raw material is evenly spread on the surface of the moving belt 5 and is conveyed forward with the belt 5. When the material passes under the magnetic separation plate 10, the strong magnetic field generated by the magnetic separation plate 10 adsorbs magnetic impurities such as iron-containing minerals on the belt 5. The non-magnetic high-purity quartz sand is not affected by the magnetic field and continues to move with the belt 5 to the end and naturally detaches, realizing the magnetic separation of quartz sand. The adjustment mechanism 7 can flexibly adjust the tension of the belt 5 to avoid slippage or incomplete separation due to the looseness of the belt 5, ensuring the separation effect. The support mechanism 6 provides stable support for the belt 5, reduces running vibration, prevents material from being bumped and dispersed, and ensures the separation accuracy.

[0024] Reference Figure 1-3 The support mechanism 6 includes a support base 61. Four support bases 61 are fixedly connected to the magnetic separation bracket 1. Support shafts 62 are rotatably connected between two adjacent support bases 61 on the left and right sides. Support rollers 63 are fixedly connected to the outer sides of the two support shafts 62.

[0025] With the above structural setup, four support seats 61 are symmetrically fixed on both sides of the magnetic separator 1. The support shaft 62 and the support roller 63 form two sets of rigid support points on the left and right sides, ensuring that the belt 5 is subjected to uniform force during operation, avoiding uneven material distribution due to local sagging or displacement, and improving the sorting stability.

[0026] Reference Figure 1-3The drive mechanism 9 includes a drive motor 91, which is fixedly connected to the magnetic separation bracket 1. A chain and sprocket transmission mechanism 92 is fixedly connected to the outside of the drive motor 91, and the chain and sprocket transmission mechanism 92 is fixedly connected to the outside of the right rotating shaft 3.

[0027] With the above structural setup, the chain and sprocket transmission mechanism 92 directly transmits the power of the drive motor 91 to the right rotating shaft 3, which has high transmission efficiency and low power loss, ensuring that the belt 5 runs at a uniform and stable speed, and avoiding uneven quartz sand sorting due to power fluctuations.

[0028] Reference Figure 1-3 The adjustment mechanism 7 includes a base plate 71. Two base plates 71 are fixedly connected to the magnetic separation bracket 1. The inner side of each base plate 71 is provided with a racetrack-shaped hole 72. A tensioning shaft 73 is placed between the two racetrack-shaped holes 72. A tensioning roller 74 is fixedly connected to the outer side of the tensioning shaft 73. The tensioning roller 74 is in close contact with the belt 5. Fixing plates 75 are fixedly connected to the front and rear sides of the magnetic separation bracket 1. A hand-tightening screw 76 is threaded to the inner side of each of the two fixing plates 75. An adjusting pressure rod 77 is rotatably connected to the outer side of each of the two hand-tightening screws 76. An arc-shaped part 78 is provided at the bottom end of each of the two adjusting pressure rods 77. The arc-shaped part 78 is adapted to the tensioning shaft 73.

[0029] With the above-described structure, rotating the hand-tightening screw 76 drives the arc-shaped part 78 of the adjusting rod 77 to push the tensioning shaft 73, which allows the tensioning roller 74 to be vertically moved within the racetrack-shaped hole 72, directly changing the tension of the belt 5. The threaded drive design of the hand-tightening screw 76 provides precise displacement control, avoiding over-adjustment or slack, and ensuring that the tension of the belt 5 is adapted to different working conditions. The arc-shaped part 78 of the adjusting rod 77 fits tightly with the tensioning shaft 73, and with the self-locking characteristic of the thread, the position of the tensioning shaft 73 is automatically fixed after adjustment, preventing the tensioning roller 74 from shifting due to vibration during equipment operation, and ensuring the long-term stability of the belt 5 tension.

[0030] Reference Figure 1-3 Two upright plates 11 are fixedly connected to the opposite sides of the two base plates 71. Guide sleeves 12 are fixedly connected between two adjacent upright plates 11 on the front and rear sides through crossbars. Two adjusting pressure rods 77 are slidably connected to the inner side of the two guide sleeves 12 respectively.

[0031] With the above structural setup, the adjusting rod 77 is slidably connected to the inside of the guide sleeve 12. Through the constraint of the guide sleeve 12, the adjusting rod 77 is ensured to move linearly in the vertical direction, avoiding radial offset or swaying of the adjusting rod 77 when the hand-tightening screw 76 is rotated. This ensures that the tensioning shaft 73 moves smoothly laterally along the racetrack-shaped hole 72, improving the accuracy of belt 5 tension adjustment.
