Description

Technical Field

[0001] This utility model relates to the field of fused silica powder production and processing technology, and in particular to a fused silica powder drying device. Background Technology

[0002] In the production and processing of fused silica powder, drying and pulverization are crucial steps. Current technologies often suffer from insufficient drying due to limitations in equipment structure and processes. Uneven airflow distribution within the drying equipment prevents some quartz powder from fully contacting the hot air, resulting in significant moisture residue. Furthermore, due to the inherent properties of quartz powder, it is prone to agglomeration during the drying process. These agglomerated quartz powder clumps are tightly packed, making it difficult to effectively break them up in subsequent pulverization processes. This significantly impacts the drying effect, leading to inconsistent final product quality and failing to meet the stringent requirements of high-end markets for high-purity, low-moisture fused silica powder. Utility Model Content

[0003] This utility model aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, the purpose of this utility model is to provide a fused silica powder drying device to crush agglomerated silica powder and fully dry the crushed silica powder.

[0005] To achieve the above objectives, this utility model proposes a fused silica powder drying device, comprising a drying chamber and an air drying mechanism and a grinding mechanism disposed within the drying chamber. The grinding mechanism includes a grinding hopper, a grinding scraper, and a collecting hopper. The grinding hopper has a conical mesh structure. The grinding scraper is rotatably disposed on the inner wall side of the grinding hopper. The collecting hopper is disposed below the grinding hopper, and a discharge port is provided at the bottom of the collecting hopper. The air drying mechanism includes an air inlet panel and an exhaust assembly. The air inlet panel is disposed at the top of the grinding hopper, and the exhaust assembly includes an exhaust fan disposed on the drying chamber.

[0006] Furthermore, a drive motor is provided below the collection hopper, a drive shaft is provided on the power shaft of the drive motor, a spring support rod is provided on the side wall of the drive shaft, and the end of the spring support rod is connected to the rolling scraper.

[0007] Furthermore, a scraper bracket is provided at the top of the rolling scraper, and the end of the spring support rod is connected to the scraper bracket. The rolling scraper and the scraper bracket are connected by an elastic pivot.

[0008] Furthermore, a feeding assembly is provided on the top of the drying chamber. The feeding assembly includes a feeding hopper, a feeding pipe, and a feeding spiral shaft. The feeding pipe is located above the grinding hopper, the feeding spiral shaft is rotatably located inside the feeding pipe, the bottom of the feeding spiral shaft is connected to a drive shaft, and the feeding hopper is located on top of the feeding pipe.

[0009] Furthermore, the exhaust fan has an exhaust filter cover at its air inlet end, which is located inside the drying chamber. The surface of the exhaust filter cover is provided with a scraper brush, and the bottom of the scraper brush is provided with a scraper motor to drive its swing. The bottom of the scraper brush is provided with a balance block. The air inlet panel has evenly distributed air inlet slots.

[0010] Furthermore, a discharge assembly is provided at the bottom of the drying chamber. The discharge assembly includes a hopper, a discharge cylinder, and a discharge screw shaft. The hopper is integrally disposed at the bottom of the drying chamber, the discharge cylinder is horizontally disposed at the bottom of the hopper, and the discharge screw shaft is rotatably disposed inside the discharge cylinder.

[0011] Furthermore, the hopper has a V-shaped cross-section, and a discharge motor that drives the discharge screw shaft to rotate is provided on the outside of the hopper.

[0012] Beneficial effects: This utility model sets a grinding hopper at the feeding end of the drying chamber. During the feeding process, the rotating grinding scraper crushes the agglomerated quartz powder in the grinding hopper. The crushed quartz powder falls from the mesh grinding hopper to the bottom of the drying chamber. At the same time, the exhaust fan generates negative pressure in the drying chamber, and air is introduced through the air intake panel above the grinding hopper to dry and guide the quartz powder ground in the grinding hopper. The powder is then fully mixed with air in the drying chamber to dry thoroughly, thus drying the crushed quartz powder completely.

Detailed Implementation

[0018] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0019] The fused silica powder drying apparatus of this utility model is described below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 As shown, the fused silica powder drying device provided in this embodiment of the present invention includes a drying chamber 3 and an air drying mechanism 2 and a grinding mechanism 5 disposed in the drying chamber 3. A drying chamber support 31 is provided at the bottom of the drying chamber 3. The grinding mechanism 5 includes a grinding hopper 51, a grinding scraper 531 and a collecting hopper 54. The grinding hopper 51 has a conical mesh structure. The grinding scraper 531 is rotatably disposed on the inner wall side of the grinding hopper 51. The collecting hopper 54 is disposed below the grinding hopper 51. A discharge port 541 is provided at the bottom of the collecting hopper 54.

[0021] The air drying mechanism 2 includes an air inlet panel 21 and an exhaust assembly 22. The air inlet panel 21 is located on the top of the grinding hopper 51, and the exhaust assembly 22 includes an exhaust fan 221 located on the drying chamber 3.

[0022] Specifically, when using the drying device of this application, the quartz powder to be dried is fed into the grinding hopper 51 from above. After the quartz powder enters the grinding hopper 51, the grinding scraper 531 rotates to crush the clumps of quartz powder in the grinding hopper 51. The crushed quartz powder falls from the mesh grinding hopper 51 to the bottom of the drying chamber 3.

[0023] While the quartz powder is being ground, the exhaust fan 221 operates to create negative pressure inside the drying chamber 3. Air is drawn in through the air intake panel 21 above the grinding hopper 51, drying and guiding the quartz powder being ground in the grinding hopper 51. The quartz powder falls rapidly from the mesh grinding hopper 51 to the discharge port 541 and enters the drying chamber 3 from the discharge port 541. Inside the drying chamber 3, the powder is thoroughly mixed with air and dried, resulting in complete drying of the crushed quartz powder. Finally, the dried quartz powder settles at the bottom of the drying chamber 3 for later collection.

[0024] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a drive motor 57 is located below the collection hopper 54, and a motor bracket 571 is located at the bottom of the drive motor 57. A drive shaft 56 is mounted on the power shaft of the drive motor 57, and a shaft bearing 55 is sleeved on the outside of the drive shaft 56. A spring support rod 52 is mounted on the side wall of the drive shaft 56, and the end of the spring support rod 52 is connected to the rolling scraper 531. A scraper bracket 53 is located at the top of the rolling scraper 531, and the end of the spring support rod 52 is connected to the scraper bracket 53. The rolling scraper 531 and the scraper bracket 53 are connected by an elastic pivot connection.

[0025] Specifically, during the crushing of quartz powder, the drive motor 57 drives the drive shaft 56 to rotate, and the drive shaft 56 drives the crushing scraper 531 at the end of the spring support rod 52 to rotate together. The crushing scraper 531 rotates and crushes the clumps of quartz on the inner wall of the grinding bucket 51, and then falls off the mesh grinding bucket 51.

[0026] During the rotation of the grinding scraper 531, the grinding scraper 531 is elastically supported by the spring support rod 52, allowing the grinding scraper 531 to elastically contact the inner wall of the grinding bucket 51, preventing hard contact damage between the grinding scraper 531 and the grinding bucket 51. The grinding scraper 531 and the scraper bracket 53 are connected by an elastic pivot, allowing the grinding scraper 531 to adapt to the protrusion changes of the inner wall of the grinding bucket 51 during the grinding process, ensuring full contact between the grinding scraper 531 and the inner wall of the grinding bucket 51.

[0027] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the top of the drying chamber 3 is provided with a feeding assembly 1, including a feeding hopper 11, a feeding pipe 12 and a feeding spiral shaft 13. The feeding pipe 12 is located above the grinding hopper 51, and the feeding spiral shaft 13 is rotatably located inside the feeding pipe 12. The bottom of the feeding spiral shaft 13 is connected to the drive shaft 56, and a spiral shaft support 14 is provided at the bottom of the feeding spiral shaft 13. The feeding hopper 11 is located at the top of the feeding pipe 12.

[0028] Specifically, during the feeding process, the quartz powder that needs to be dried is fed into the feeding hopper 11. The driving shaft 56 drives the grinding scraper 531 to rotate while also driving the material distribution spiral shaft 13 in the feeding pipe 12 to rotate, so that the quartz powder in the feeding hopper 11 is evenly fed into the grinding hopper 51.

[0029] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the exhaust fan 221 has an exhaust filter 222 at its air inlet end. The exhaust filter 222 is located inside the drying chamber 3. The surface of the exhaust filter 222 is provided with a scraper brush 223. The bottom of the scraper brush 223 is provided with a scraper motor 224 that drives it to swing. The bottom of the scraper brush 223 is provided with a balance block 225 to balance the swing force of the scraper brush 223. The air inlet panel 21 has evenly distributed air inlet slots 23.

[0030] Specifically, during the exhaust process of the exhaust fan 221, air enters the grinding hopper 51 through the air intake slot 23 on the air intake panel 21, causing the quartz powder on the grinding hopper 51 to be quickly sieved into the drying chamber 3, where the quartz powder is further mixed with the air to dry the quartz powder.

[0031] Quartz powder mixed with air in the drying chamber 3 is intercepted and filtered by the exhaust filter 222. While the exhaust filter 222 is filtering, the scraper brush 223 on its surface is driven by the scraper motor 224 to reciprocate and sweep, so that the surface of the exhaust filter 222 is always breathable and clean.

[0032] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the bottom of the drying chamber 3 is provided with a discharge assembly 4, including a hopper 43, a discharge cylinder 41 and a discharge screw shaft 45. The hopper 43 is integrally disposed at the bottom of the drying chamber 3, the discharge cylinder 41 is horizontally disposed at the bottom of the hopper 43, and the discharge screw shaft 45 is rotatably disposed inside the discharge cylinder 41.

[0033] The hopper 43 has a V-shaped cross-section, and a discharge motor 44 that drives the discharge screw shaft 45 to rotate is installed on the outside of the hopper 43.

[0034] Specifically, during the discharge process, the dried quartz powder in the drying chamber 3 falls into the bottom of the hopper 43 and enters the discharge cylinder 41. The discharge spiral shaft 45 in the discharge cylinder 41 is driven to rotate by the discharge motor 44, and the quartz powder is discharged from the discharge nozzle 42.

[0035] To clearly illustrate the above embodiments, refer to Figure 1 and Figure 2The specific working principle of the fused silica powder drying device of this utility model is as follows: When using the drying device of this application, the silica powder to be dried is first fed into the feeding hopper 11, and the driving shaft 56 drives the feeding pipe 12 to rotate the feeding spiral shaft 13, so that the silica powder in the feeding hopper 11 is evenly fed into the grinding hopper 51.

[0036] After the quartz powder enters the grinding hopper 51, the drive motor 57 drives the drive shaft 56 to rotate. The drive shaft 56 drives the grinding scraper 531 at the end of the spring support rod 52 to rotate together, thereby driving the grinding scraper 531 to rotate and grind on the inner wall of the grinding hopper 51, crushing the clumps of quartz. The crushed quartz powder is then screened off the mesh-like grinding hopper 51.

[0037] While the quartz powder is being ground, the exhaust fan 221 operates to create negative pressure inside the drying chamber 3. Air enters through the air inlet panel 21 above the grinding hopper 51, drying and guiding the quartz powder being ground in the grinding hopper 51. This causes the quartz powder to fall rapidly from the mesh grinding hopper 51 to the discharge port 541, and then enter the drying chamber 3 from the discharge port 541. Inside the drying chamber 3, the quartz powder is further mixed with air, thus drying the quartz powder.

[0038] Quartz powder mixed with air in the drying chamber 3 is intercepted and filtered by the exhaust filter 222. While the exhaust filter 222 is filtering, the scraper brush 223 on its surface is driven by the scraper motor 224 to reciprocate and sweep, so that the surface of the exhaust filter 222 is always breathable and clean.

[0039] Finally, the dried quartz powder in the drying chamber 3 falls to the bottom of the hopper 43 and enters the discharge cylinder 41. The discharge spiral shaft 45 in the discharge cylinder 41 is driven to rotate by the discharge motor 44, and the quartz powder is discharged from the discharge nozzle 42.

[0040] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
