Description

Technical Field

[0001] This utility model relates to the field of fused silica processing technology, specifically to a sieving device for fused silica particles. Background Technology

[0002] Fused silica is an amorphous (glassy) state 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 the cross-linking of its three-dimensional structure. Fused silica requires a sieving device during processing and grading.

[0003] In existing technologies, screening devices typically feed molten silica particles directly into an inclined filter screen for screening. However, due to the varying particle sizes of the molten silica particles, incomplete screening of particles of different sizes occurs during centralized feeding, resulting in poor screening efficiency. A screening device for molten silica particles is needed to address these problems. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a screening device for fused silica particles to solve the problems mentioned in the background art. This utility model has a reasonable structure, complete screening, and good screening effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a sieving device for fused silica particles, comprising:

[0006] The housing has multiple sieve filters arranged from top to bottom with decreasing aperture sizes and tilting downwards.

[0007] A cylindrical body is provided above the housing, and a drive motor is provided at the end of the cylindrical body. An auger shaft located inside the cylindrical body is provided on the output shaft of the drive motor. An arc-shaped filter screen is provided at the bottom of the cylindrical body. A material guide channel is provided at the bottom of the cylindrical body and is connected to the upper side of the inner wall of the housing to cover the arc-shaped filter screen. A feed pipe for connecting to the inside of the housing is provided on one side of the bottom of the cylindrical body.

[0008] Furthermore, each of the screening and filtering screens is provided with a guide plate located inside the housing, the guide plate is inclined downwards, and the lower end of the guide plate is located directly above the upper end of the screening and filtering screen.

[0009] Furthermore, a support plate is symmetrically arranged on the top of the shell, and an arc-shaped groove matching the side wall of the cylinder is opened on the top of the support plate.

[0010] Furthermore, a feed inlet is provided at the top of the cylinder, and a feed hopper is provided inside the feed inlet.

[0011] Furthermore, the housing is provided with an inclined plate located below the bottommost screening and filtering screen, and a vibration motor is provided at the bottom of the inclined plate.

[0012] Furthermore, the side wall of the housing is provided with a discharge port that communicates with the lower end of the screening filter screen and the lower end of the inclined plate, and the side wall of the housing is provided with a guide plate located below the discharge port.

[0013] The beneficial effects achieved by the present invention using the above structure are as follows:

[0014] This invention uses a drive motor to rotate an auger shaft, which in turn causes molten silica particles to be conveyed and tumbled inside the cylinder. Small molten silica particles pass through an arc-shaped filter screen during conveying and tumbling, and are then screened sequentially through multiple screening screens. Larger molten silica particles flow out from the feed pipe and are also screened sequentially through multiple screening screens. By separating the small and large molten silica particles for feeding, concentrated screening is avoided, ensuring that molten silica particles of different sizes are completely screened before being discharged, resulting in a good screening effect.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1 As shown, this utility model provides a technical solution: a sieving device for fused silica particles, comprising:

[0023] The housing 1 has multiple sieve filters 9 arranged from top to bottom with decreasing aperture sizes and tilting downwards.

[0024] A cylindrical body 3 is positioned above the shell 1. A drive motor 2 is located at the end of the cylindrical body 3. An auger shaft 21 located inside the cylindrical body 3 is mounted on the output shaft of the drive motor 2. An arc-shaped filter screen 11 is located at the bottom of the cylindrical body 3. A guide channel 4, connected to the upper inner wall of the shell 1 and used to cover the arc-shaped filter screen 11, is located at the bottom of the cylindrical body 3. A discharge pipe 5, connecting to the interior of the shell 1, is located on one side of the bottom of the cylindrical body 3. This design places molten silica particles inside the cylindrical body 3. The drive motor 2 rotates the auger shaft 21, which in turn causes the molten silica particles to be conveyed and tumbled inside the cylindrical body 3. Small molten silica particles pass through the arc-shaped filter screen 11 during conveying and tumbling, and are then screened sequentially through multiple screening filters 9. Large molten silica particles flow out from the discharge pipe 5 and are also screened sequentially through multiple screening filters 9. By separating small and large molten silica particles for discharge, concentrated screening is avoided, and molten silica particles of different sizes are completely screened before being discharged, resulting in good screening effect.

[0025] Reference Figure 2 and Figure 3 Each screening filter screen 9 is equipped with a guide plate 10 located inside the housing 1. The guide plate 10 is inclined downwards, with its lower end directly above the upper end of the screening filter screen 9. This design, through the guide plate 10, facilitates the delivery of molten quartz to the upper end of the screening filter screen 9, further ensuring that the molten quartz is completely screened and discharged, thus enhancing the screening effect.

[0026] Reference Figure 1 and Figure 4 The top of the shell 1 is symmetrically provided with support plates 6, and the top of the support plates 6 has an arc-shaped groove that matches the side wall of the cylinder 3. This design facilitates the support of the cylinder 3 through the support plates 6.

[0027] Reference Figure 1 and Figure 2 The top of the cylinder 3 is provided with a feed inlet, and a feed hopper 31 is provided inside the feed inlet. This design facilitates the feeding of molten quartz into the cylinder 3 through the feed hopper 31.

[0028] Reference Figure 2 and Figure 3The housing 1 has an inclined plate 12 located below the bottom screening filter screen 9 inside, and a vibration motor 13 is installed at the bottom of the inclined plate 12. This improves the rationality of the design.

[0029] Reference Figure 1 and Figure 3 The shell 1 has a discharge port 8 on its side wall, which is connected to the lower end of the screening filter screen 9 and the lower end of the inclined plate 12. The shell 1 also has a guide plate 7 located below the discharge port 8 on its side wall. This design facilitates the discharge of molten quartz from the interior of the shell 1 through the discharge port 8 and the guide plate 7.

[0030] Reference Figures 1-4 As an embodiment of this utility model: when it is necessary to screen fused silica particles, the operator feeds the fused silica particles into the cylinder 3 through the feed hopper 31. The drive motor 2 drives the auger shaft 21 to rotate, and the auger shaft 21 drives the fused silica particles to be conveyed and tumbled inside the cylinder 3. Small fused silica particles pass through the arc-shaped filter screen 11 during conveying and tumbling, while large fused silica particles flow out from the feed pipe 5 and fall onto the guide plate 10. The fused silica is sent to the high end of the screening filter screen 9, ensuring that the fused silica is completely screened before being discharged, thus enhancing the screening effect. By separating the small and large fused silica particles for feeding, centralized screening is avoided, and fused silica particles of different sizes are completely screened before being discharged, resulting in a good screening effect and improving the practicality of this utility model.
