Description

Technical Field

[0001] This utility model relates to the technical field of quartz sand grinding equipment, and in particular to a high-purity quartz sand ultrafine powder processing equipment. Background Technology

[0002] High-purity silica sand needs to be processed into an ultrafine powder state (typically with particle sizes reaching the micron or even nanometer scale) to meet the stringent requirements of product materials for material purity and particle size uniformity. The grinding quality of ultrafine silica sand powder directly affects the performance of downstream products.

[0003] In the prior art, Chinese Patent No. CN 220531804 U discloses a grinding mechanism for a quartz sand grinding device, belonging to the technical field of quartz sand processing equipment. It includes: a support plate, a connecting plate fixedly connected to the top of the support plate, a grinding box fixedly connected to one end of the connecting plate, and a crushing motor installed on one side of the grinding box.

[0004] In this patent, the distance between the grinding plate and the grinding block is constant; in the initial stage, the quartz sand can be crushed by the rotation of the grinding block, making the particles gradually smaller. However, when the quartz sand particles are refined to a certain extent, the distance between the grinding block and the grinding plate cannot be further reduced, and the fine particles easily form a "buffer layer" in the gap, making it difficult for the grinding block to apply sufficient grinding pressure and further refine the particles. Utility Model Content

[0009] In one embodiment, a limiting ring is fixedly connected to the lifting plate, the limiting ring is provided with multiple sets of limiting grooves, multiple sets of limiting strips are fixedly connected to the outside of the grinding table, and multiple sets of grinding balls are fixedly connected to the bottom of the grinding disc.

[0010] In one embodiment, magnets are fixedly connected to the bottom of the grinding table and the inner bottom of the limiting ring, and the magnets are arranged with opposite poles attracting each other.

[0012] In one embodiment, a limiting rod is fixedly connected to the base, and the limiting rod passes through the rack.

[0013] The beneficial effects of this utility model are as follows: Compared with the prior art, in this utility model, after the quartz sand is poured onto the grinding table, the grinding disc is rotated by the motor to grind the quartz sand.

[0022] The following is in conjunction with the appendix Figure 1-5 The present invention will be further described below.

[0023] To address the problems existing in the background technology, this application proposes the following technical solution: a high-purity quartz sand ultrafine powder processing equipment, including a base 1, a gear 5 rotatably connected to the base 1, a top frame 6 fixedly connected to the top of the gear 5, a motor 7 fixedly connected to the top frame 6, a grinding disc 15 fixedly connected to the output end of the motor 7, a lifting plate 8 provided in the top frame 6, a grinding table 11 provided on the top of the lifting plate 8, a lifting component for pushing the lifting plate 8 to slide on the gear 5, a driving component for driving the gear 5 to reciprocate, and multiple sets of guide rods 9 fixedly connected between the top frame 6 and the gear 5, the guide rods 9 passing through the lifting plate 8; the base 1, as the basic support of the entire equipment, is made of heavy cast iron material, which can effectively absorb the vibration generated during the operation of the equipment and ensure the overall stability of the equipment. The gear 5 rotatably connected to the base 1 is the core component for realizing the swing function of the equipment. Its fixed connection with the top frame 6 allows the top frame 6 to rotate together with the gear 5, thereby driving the grinding-related components to achieve angle adjustment. The top frame 6 provides an installation platform for components such as the motor 7 and the lifting plate 8, ensuring that each component maintains a stable relative position during operation.

[0024] Motor 7 provides rotational power to the grinding disc 15. Its fixed connection to the grinding disc 15 ensures efficient power transmission, allowing the grinding disc 15 to grind the quartz sand at a stable rotational speed. Lifting plate 8 supports the grinding table 11 and slides up and down via a lifting assembly, facilitating adjustment of the distance between the grinding table 11 and the grinding disc 15 to accommodate different grinding fineness requirements. The lifting assembly precisely controls the height of lifting plate 8, ensuring stable pressure between the grinding table 11 and the grinding disc 15 during grinding, thus improving the grinding effect.

[0025] The drive assembly drives the gear 5 to reciprocate, causing the top frame 6 and related components to swing accordingly. This allows the quartz sand in the grinding table 11 to be subjected to grinding forces in different directions, preventing localized accumulation and achieving uniform grinding. Multiple guide rods 9 between the top frame 6 and the gear 5 pass through the lifting plate 8, not only guiding the sliding of the lifting plate 8 and preventing it from shifting during lifting, but also enhancing the overall rigidity of the connection between the top frame 6 and the gear 5, reducing deformation during swinging. This integrated structural design combines rotary grinding with reciprocating swinging, significantly improving the grinding uniformity and fineness of the quartz sand, meeting the processing requirements of high-purity quartz sand ultrafine powder.

[0026] In this embodiment, the lifting assembly is a hydraulic cylinder 14 fixedly connected to the gear 5. At least one set of hydraulic cylinders 14 is provided, and the output end of the hydraulic cylinder 14 is fixedly connected to the lifting plate 8. The lifting assembly uses the hydraulic cylinder 14 as a power source, which has the characteristics of large output force, smooth operation, and precise control. It can provide sufficient thrust for the lifting plate 8 to move up and down, ensuring that the grinding table 11 can stably approach or move away from the grinding disc 15. The hydraulic cylinder 14 is fixed on the gear 5 and rotates with the gear 5, ensuring that the lifting plate 8 can still be driven normally during the swinging process of the equipment, and the power transmission will not be affected by the change of position.

[0027] At least one set of hydraulic cylinders 14 can be adjusted according to the size and weight of the lifting plate 8. The synchronous operation of multiple sets of hydraulic cylinders 14 can make the lifting plate 8 evenly stressed, avoid tilting during the lifting process, and ensure the parallelism between the grinding table 11 and the grinding disc 15, so that the quartz sand is subjected to uniform grinding force. The output end of the pressure cylinder is fixedly connected to the lifting plate 8, and the connection part is fastened with high-strength bolts, which can withstand the reaction force generated during the grinding process and ensure the reliability of the lifting action.

[0028] By extending and retracting the hydraulic cylinder 14, the operator can precisely control the gap between the grinding table 11 and the grinding disc 15. The smaller the gap, the finer the quartz sand powder produced, meeting the processing requirements of different fineness levels. This adjustment method is simple to operate, requiring only the hydraulic control system, without the need for stopping the machine for complex mechanical adjustments, thus improving the flexibility and efficiency of the equipment. The stable operation of the hydraulic cylinder 14 ensures constant grinding pressure, avoiding inconsistent grinding results caused by pressure fluctuations, and contributing to improved product quality stability.

[0029] In this embodiment, a limiting ring 10 is fixedly connected to the lifting plate 8. The limiting ring 10 has multiple sets of limiting grooves 13. Multiple sets of limiting strips 12 are fixedly connected to the outside of the grinding table 11. Multiple sets of grinding balls 16 are fixedly connected to the bottom of the grinding disc 15. Magnets are fixedly connected to the bottom of the grinding table 11 and the inner bottom of the limiting ring 10, with opposite poles of the magnets attracting each other. The limiting ring 10 on the lifting plate 8 positions and fixes the grinding table 11. The multiple sets of limiting grooves 13 in the limiting ring 10 cooperate with the limiting strips 12 on the outside of the grinding table 11 to form a precise snap-fit ​​structure, preventing the grinding table 11 from rotating or shifting during equipment swing and grinding, and ensuring the relative position of the grinding table 11 and the grinding disc 15 is stable. This snap-fit ​​method makes the installation and disassembly of the grinding table 11 simple and facilitates later cleaning and maintenance.

[0030] The multiple sets of grinding balls 16 at the bottom of the grinding disc 15 are made of high-strength wear-resistant material, which can fully crush and grind the quartz sand, increasing the contact area between the grinding disc 15 and the quartz sand and improving grinding efficiency. The uniform distribution of the grinding balls 16 ensures that the quartz sand is subjected to uniform force during the grinding process, avoiding local over-grinding or under-grinding and ensuring the consistency of product particle size.

[0031] The magnets at the bottom of the grinding table 11 and the inner bottom of the limiting ring 10 attract each other, further enhancing the stability of the grinding table 11 installation. This effectively prevents the grinding table 11 from detaching from the limiting ring 10 due to vibration during equipment swinging and grinding. The magnet's attraction is moderate, ensuring a secure connection without affecting the normal placement and removal of the grinding table 11. Operators can easily and quickly remove the grinding table 11 from the limiting ring 10 with minimal force. This double-fixing structure (the limiting groove 13 engages with the limiting strip 12, and the magnet attracts the grinding table 11) ensures the stability of the grinding table 11 during operation, providing a reliable guarantee for uniform grinding.

[0032] In this embodiment, the drive assembly includes a cylinder 2 and a rack 3. The cylinder 2 is fixedly connected to the base 1, and the rack 3 is fixedly connected to the output end of the cylinder 2. A limit rod 4 is fixedly connected to the base 1, and the limit rod 4 passes through the rack 3. The cylinder 2 in the drive assembly serves as a power source, featuring fast response and smooth operation. It can drive the rack 3 to quickly achieve reciprocating motion, providing power for the reciprocating rotation of the gear 5. The cylinder 2 is fixed to the base 1, ensuring a firm connection and the ability to withstand the reaction force generated when the rack 3 moves, thus guaranteeing the stability of the power output.

[0033] The rack 3 is rigidly connected to the output end of the cylinder 2, ensuring that the extension and retraction of the cylinder 2 is fully transmitted to the rack 3, allowing the rack 3 to move stably in a straight line. The limiting rod 4 on the base 1 passes through the rack 3, providing guidance for the movement of the rack 3 and preventing the rack 3 from deviating or wobbling during reciprocating motion. This ensures that the rack 3 and the gear 5 always maintain a good meshing state, avoiding power transmission loss or component wear due to poor meshing.

[0034] The limiting rod 4 enhances the straightness of the rack 3's movement, making the reciprocating rotation of the gear 5 smoother. This ensures uniform oscillation of the top frame 6 and related components, guaranteeing that the quartz sand in the grinding table 11 is subjected to grinding force in different directions, thus improving grinding uniformity. The reciprocating frequency of the cylinder 2 can be adjusted by the control system to adapt to the needs of different grinding stages. A higher frequency can be used in the initial stage to quickly disperse the quartz sand, while a lower frequency is used for fine grinding in the later stages. The design of the drive assembly enables the equipment to achieve a reciprocating oscillation function, which, combined with the rotational motion of the grinding disc 15, significantly improves the grinding effect and fineness of the quartz sand, meeting the processing requirements of high-purity quartz sand ultrafine powder.

[0035] The usage method of this embodiment is as follows:

[0036] Pour the quartz sand to be ground into the grinding table 11, then place the grinding table 11 in the limiting sleeve, so that the limiting strip 12 is engaged in the limiting groove 13. Then start the hydraulic cylinder 14 to push the lifting plate 8 upward until the grinding table 11 surrounds the outside of the grinding disc 15. Then start the motor 7 to drive the grinding disc 15 to rotate, and grind the quartz sand through the grinding disc 15.

[0037] In addition, during the grinding process, the cylinder 2 can be activated to drive the rack 3 to reciprocate, the rack 3 drives the gear 5 to reciprocate, the gear 5 drives the top frame 6 to reciprocate, thereby driving the grinding table 11 and the grinding disc 15 to swing, so that the quartz sand in the grinding table 11 can be fully ground.

[0038] After grinding is complete, turn off motor 7, start hydraulic cylinder 14 to drive lifting plate 8 downward until grinding table 11 leaves grinding disc 15, and then remove grinding table 11.
