Description

Technical Field

[0001] The utility model relates to the technical field of crucible production, in particular to a raw material filtering device for producing quartz crucibles. Background Art

[0002] Quartz crucibles, with their high purity, strong temperature resistance, large size and high precision, good thermal insulation, energy conservation, and stable quality, are becoming increasingly popular. Translucent quartz crucibles made using the arc method are essential basic materials for pulling large-diameter single crystal silicon and developing large-scale integrated circuits. During the crucible production process, filtering and filtration of the raw materials are extremely important.

[0003] Existing raw material filtering devices for quartz crucible production usually filter the raw materials through a vibrating screen. However, the screen plate is prone to clogging during use, which affects the efficiency and quality of raw material filtration. In addition, the iron impurities in the raw materials cannot be removed during the filtration process. Iron will oxidize at high temperature during the processing process, causing black spots and other problems in the product, which greatly affects the quality of the product. Utility Model Content

[0023] Example 1

[0024] Combined with attachment Figure 1 A raw material filtering device for quartz crucible production includes a bottom plate 1, a pair of support plates 2 are vertically and symmetrically installed on both sides of the upper end of the bottom plate 1, a sieve barrel 3 is connected to the bearing at the upper position between the pair of support plates 2, a motor 4 driven by the sieve barrel 3 is installed on the outer side of one of the support plates 2, an anti-blocking cleaning component 5 acting on the sieve barrel 3 is detachably installed at the rear end of the pair of support plates 2, a collecting cover 6 is installed in the middle of the pair of support plates 2, and an iron removal component 7 is provided at the lower end of the collecting cover 6, and a collecting box 1 8 and a collecting box 2 9 are placed on the upper end of the bottom plate 1.

[0025] Combined with attachment Figure 2 The sieve barrel 3 is provided with a plurality of annular equidistant sieve holes 301, and a barrel cover 10 connected to the motor 4 is installed at one end of the sieve barrel 3. An opening is provided on the outside of the sieve barrel 3 and a cover plate 11 is hingedly installed at the opening.

[0026] In combination with the above structure, after the quartz crucible raw material is placed into the screen barrel 3 by opening the cover 11, the cover 11 is closed, and the screen barrel 3 is driven to rotate by the motor 4, so that the fine raw material is filtered out.

[0027] Combined with attachment Figure 2 The anti-blocking cleaning component 5 includes an L-shaped clamping plate 12 fixed to the rear end of the support plate 2, and a pair of mounting plates 13 are clamped on the L-shaped clamping plates 12. A brush 14 in contact with the rear side wall of the screen barrel 3 is installed on the inner side of the mounting plate 13.

[0028] Combined with the above structure, when the screen barrel 3 rotates, its outer wall contacts the brush 14, and the large particles of raw materials blocked on the screen holes 301 are cleaned out by the brush 14, preventing a large number of screen holes 301 from being blocked, resulting in reduced efficiency and quality of raw material filtration; and the mounting plate 13 is clamped on a pair of L-shaped clamping plates 12, so that the mounting plate 13 is easy to install and disassemble, thereby making the brush 14 easy to install and disassemble, and easy to replace.

[0029] Combined with attachment Figure 2 The upper end of the collecting cover 6 is larger than the size of the screen barrel 3, which is convenient for collecting the raw materials screened out by the screen barrel 3. The lower end of the collecting cover 6 is connected to a rectangular discharge pipe 15.

The magnet drum 17 is driven to rotate by the motor 2 18, thereby taking away the iron impurities and scraping them off through the scraper 20, thereby separating the raw material from the iron impurities, preventing the iron from being oxidized at high temperature during the processing process, causing black spots and other problems in the product, and ensuring the quality of the product.

[0034] Combined with attachment Figure 3 The collecting box 1 8 and the collecting box 2 9 are respectively located on both sides of the lower end of the magnet drum 17. The filtered raw materials and iron impurities are collected by the collecting box 1 8 and the collecting box 2 9 respectively, which is convenient for collection and processing.

The large particles of raw material blocking the sieve holes 301 are cleaned out by the brush 14 to prevent a large number of sieve holes 301 from being blocked. The filtered raw material is collected by the collecting cover 6 and discharged to the magnet drum 17 through the rectangular discharge pipe 15. The iron impurities in the raw material are adsorbed by the magnet drum 17, which is driven to rotate by the motor 2 18, thereby taking away the iron impurities and scraping them off by the scraper 20.

In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
