Description

Technical Field

[0001] This utility model relates to the field of quartz powder technology, specifically to a high-purity fused quartz powder grinding device. Background Technology

[0002] Quartz powder is a powder produced from pure quartz through multiple processes including crushing, sorting, washing, acid treatment, high-temperature melting, medium crushing, fine grinding, grading, and iron removal. Since quartz particles are relatively large, they need to be ground to form quartz powder. Quartz powder is produced using two methods: dry and wet processing. Various standard sizes are available: 100M, 150M, 200M, 325M, 400M, 600M, 1500M, and 2000M (M represents mesh size). Custom sizes can also be processed according to customer requirements. Dry quartz powder production mainly uses equipment such as a stone crusher, pulverizer, and vibrating screen. The process involves processing quartz ore into smaller stones using a stone crusher, then further crushing the stones into sand particles using a pulverizer, followed by screening using a vibrating screen. During screening, magnetic rods and magnetic separators are used to remove iron. The finished product is then packaged and stored. The water-based method for producing quartz powder primarily uses equipment such as a stone crusher, stone mill, drying oven, vibrating screen, and water system. The general process is as follows: Quartz ore is processed into smaller stones using a stone crusher, then crushed into sand particles using a stone mill. Water is continuously added during crushing, carrying the sand particles into a sedimentation tank. The sand particles from the sedimentation tank are then transported to a drying oven to dry into dry sand particles. These dry-processed sand particles are then screened using a vibrating screen, where magnetic rods and magnetic separators are used to remove iron. The finished product is then packaged and stored. The dry-process quartz powder is available in two grades: ordinary quartz powder and refined quartz powder. Because quartz ore naturally has a yellowish-brown outer layer when it is mined from the mountains. The product obtained by directly crushing and screening smaller quartz ore is called ordinary quartz powder. It has a yellowish-brown and white appearance. Its advantage is that it is inexpensive, but its disadvantage is that it contains more impurities, so it is mostly used in the construction industry. Larger ore is selected, and the yellowish-brown outer skin is removed manually. The resulting product is refined quartz powder. It has a white, shiny appearance, like white sugar. Because the processing is time-consuming and material-intensive, it is more expensive.

[0003] Most high-purity fused silica powder grinding devices currently on the market have the following problems during use:

[0004] Traditional high-purity fused silica powder grinding devices produce some larger quartz particles after grinding and filtration. These larger particles require complete disassembly of the grinding device to collect, which is time-consuming and labor-intensive, increasing the difficulty of operation. Furthermore, traditional high-purity fused silica powder grinding devices generate a large amount of dust during the grinding process, which cannot be blocked at the feed inlet, causing dust to pollute the external environment and thus posing a certain degree of pollution during use. Utility Model Content

[0005] (a) Technical problems to be solved

By installing a support plate inside the tank and connecting a filter screen inside the inner groove, the quartz powder produced after grinding will be filtered through the filter screen. Larger particles of quartz powder will adhere to the surface of the filter screen. The operator can pull out the support plate to collect the residual quartz powder immediately for further grinding, saving time and effort and reducing the difficulty of operation.

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.

[0026] Please see Figure 1-6 This utility model provides a technical solution: a high-purity fused silica powder grinding device, including a device body 1, a groove 9 is formed inside the device body 1, a support plate 13 is connected inside the groove 9 by an inlay, an inner groove 15 is formed inside the support plate 13, a filter screen 16 is connected inside the inner groove 15, a limiting plate 5 is fixedly connected to the outside of the support plate 13, an insert block 14 is fixedly connected to the outside of the limiting plate 5, a slot 8 is formed on the outside of the device body 1, and the insert block 14 is connected inside the slot 8 by an inlay.

[0027] The quartz powder produced after grinding will be filtered through filter screen 16. Larger quartz powder particles will adhere to the surface of filter screen 16. As the usage time increases, the staff can pull out the support plate 13 to collect the residual quartz powder for re-grinding, saving time and effort and reducing the difficulty of operation.

[0028] The device body 1 is externally connected to a rotating shaft 4, and the rotating shaft 4 is externally connected to a baffle 7. The device body 1 has an external feed inlet 21, and the baffle 7 is located outside the feed inlet 21. During grinding, the baffle 7 is rotated by the rotating shaft 4 to tilt, and the quartz stone to be ground is poured into the inside of the device body 1. Then, the rotating shaft 4 is rotated again to make the baffle 7 fit against the outside of the feed inlet 21, so that the feed inlet 21 is closed. In this way, the dust generated during grinding will not be transmitted to the external environment.

[0029] The device body 1 is internally fixedly connected to a fixing block 19, and the support plate 13 is located on top of the fixing block 19. The bottom of the device body 1 is provided with a discharge port 20. When the support plate 13 is placed inside the device body 1, the fixing block 19 will support the support plate 13 to prevent the support plate 13 from becoming unstable.

[0030] The device body 1 has a top cover 2 on its top. The bottom of the top cover 2 is connected to a hydraulic device 10. The bottom of the hydraulic device 10 is connected to a telescopic rod 11. The bottom of the telescopic rod 11 is connected to a grinding body 12. During grinding, the hydraulic device 10 assists the telescopic rod 11 to extend and retract, so that the grinding body 12 contacts the quartz stone for better grinding.

[0031] The device body 1 is internally connected to a fixed disk 17. The fixed disk 17 has transfer holes 18 inside. The transfer holes 18 are evenly distributed. The grinding body 12 will contact the fixed disk 17, and the quartz powder produced by grinding will be transferred to the bottom through the transfer holes 18.

[0032] The device body 1 is externally fixedly connected to the limiting frame 3, and the upper cover 2 is connected to the inside of the limiting frame 3 by means of embedding. When the upper cover 2 is installed on the top of the device body 1, the limiting frame 3 will be fixed to the outside of the upper cover 2, thus playing a limiting role.

[0033] The bottom of the device body 1 is connected to the support base 6 by welding. The support base 6 is evenly distributed. As the usage time increases, the support base 6 can provide support, thereby improving the stability during use.

[0034] The working principle of this high-purity fused silica powder grinding device is as follows: First, place the device body 1 in the desired position. Then, install the top cover 2 on top of the device body 1, while the limiting frame 3 is fixed to the outside of the top cover 2, providing a secure fit. Next, the baffle 7 is rotated via the rotating shaft 4 to an inclined state, allowing the quartz to be ground to be poured into the interior of the device body 1. Then, the rotating shaft 4 is rotated again to make the baffle 7 fit against the outside of the feed inlet 21, thus closing the feed inlet 21. Then, the hydraulic device 10... The auxiliary telescopic rod 11 extends and retracts, allowing the grinding body 12 to contact the fixed disc 17 for grinding. The lime powder produced during grinding is transferred to the bottom through the transfer hole 18, and the quartz powder produced is filtered through the filter screen 16. Larger quartz powder particles adhere to the surface of the filter screen 16, while smaller quartz powder particles flow out through the discharge port 20. As the usage time increases, the operator can pull out the support plate 13 to collect and remove the remaining quartz powder for further grinding, saving time and effort and reducing the difficulty of operation.

[0035] This utility model comprises: 1. Device body; 2. Top cover; 3. Limiting frame; 4. Rotating shaft; 5. Limiting plate; 6. Support base; 7. Baffle; 8. Slot; 9. Groove; 10. Hydraulic device; 11. Telescopic rod; 12. Grinding body; 13. Support plate; 14. Insert block; 15. Inner groove; 16. Filter screen; 17. Fixed disc; 18. Transfer hole; 19. Fixed block; 20. Discharge port; 21. Inlet port. All components are general standard parts or parts known to those skilled in the art. The structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. The problem solved by this utility model is that quartz powder can be produced by two methods: dry method and water method. Various conventional specifications are available: 100M, 150M, 200M, 325M, 400M, 600M, 1500M and 2000M (M is the mesh number). In addition, special specifications can also be processed according to customer requirements. Generally, it is also possible to process quartz powder with requirements on particle size distribution. The main equipment for dry method production of quartz powder includes stone crusher, crusher, vibrating screen, etc. The process involves processing quartz ore into smaller stones using a stone crusher, then further crushing the stones into sand particles using a pulverizer, followed by screening using a vibrating screen. During screening, magnetic rods and magnetic separators are used to remove iron. The finished product is then packaged and stored. The water-based method for producing quartz powder primarily uses equipment such as a stone crusher, stone mill, drying oven, vibrating screen, and water system. The general process is as follows: Quartz ore is processed into smaller stones using a stone crusher, then crushed into sand particles using a stone mill. Water is continuously added during crushing, carrying the sand particles into a sedimentation tank. The sand particles from the sedimentation tank are then transported to a drying oven to dry into dry sand particles. These dry-processed sand particles are then screened using a vibrating screen, where magnetic rods and magnetic separators are used to remove iron. The finished product is then packaged and stored. The dry-process quartz powder is available in two grades: ordinary quartz powder and refined quartz powder. Because quartz ore naturally has a yellowish-brown outer layer when it is mined from the mountains.The product of directly crushing and screening smaller quartz ore is called ordinary quartz powder. It has a yellowish-brown and white appearance. Its advantage is that it is cheap, but its disadvantage is that it contains more impurities, so it is mostly used in the construction industry. Larger ore is selected, and the yellowish-brown outer skin is removed manually. The resulting product is refined quartz powder. It has a white and shiny appearance, like white sugar. Because the processing is time-consuming and material-intensive, the price is higher. In actual use, traditional high-purity fused quartz powder grinding equipment will produce some larger quartz particles after grinding and filtering. The grinding equipment needs to be completely disassembled to collect the larger quartz particles, which is time-consuming and laborious, and increases the difficulty of operation. Traditional high-purity fused silica powder grinding devices generate a large amount of dust during the grinding process, and since the feed inlet cannot be blocked, the dust contaminates the external environment, causing pollution. This invention addresses this issue by combining the aforementioned components. A support plate is installed inside the tank, and a filter screen is connected inside the groove. The quartz powder produced after grinding is filtered through the filter screen, while larger particles adhere to its surface. The operator can then remove the support plate to collect the remaining quartz powder for further grinding, saving time and effort and reducing operational difficulty.

It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
