Description

Technical Field

[0001] This utility model relates to the field of quartz sand purification technology, specifically a quartz sand purification device. Background Technology

[0002] In conventional quartz crucible production, crucible melting and forming is the most crucial step, and high-purity quartz sand used in this process is a vital raw material. Therefore, the particle size and true density of the quartz sand significantly influence the quality of the crucible melting and forming process. Existing quartz sand particle size distribution devices use fixed screens, resulting in uneven distribution of the quartz sand after it falls onto the screens. This leads to insufficient fine particle size separation and fails to meet the requirements for fine particle size separation of different types of quartz sand, resulting in poor particle size separation efficiency. Therefore, there is a need to provide a quartz sand purification device to address the problem of poor particle size separation efficiency in existing technologies.

[0003] Chinese Utility Model Publication No. CN219463994U discloses a quartz sand purification device, applied in the field of quartz crucible processing. It includes a discharge pipe, a sprayer and a sprayer drive device, a screen-separating bin, and a discharge bin. The sprayer is located between the output end of the discharge pipe and the screen-separating bin to spray the quartz sand falling from the discharge pipe into different areas of the screen-separating bin. The sprayer drive device is connected to the sprayer. The screen-separating bin includes a screen. The discharge bin is located below the screen-separating bin.

[0004] The device achieves the purpose of efficient and effective fine separation of high-purity quartz sand. However, when the sprayer rapidly sprays the material, the coarse material cannot accurately pass through the mesh when it hits the side wall of the screen. Some of the coarse material will bounce back and fall to the bottom of the screen, accumulating more and more, thus reducing the screening effect. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] In the prior art, a quartz sand purification device includes a discharge pipe 1, a sprayer 2 and a sprayer 2 driving device, a screen 3 particle distribution bin, a discharge bin and a particle distribution bin driving device. The particle distribution bin driving device is connected to the screen 3 particle distribution bin. The screen 3 particle distribution bin includes a screen 3. The discharge bin includes a high-purity sand discharge bin 7 and a coarse sand discharge bin 8. The screen 3 particle distribution bin includes a first screen 3 and a second screen 3. The first screen 3 is located in the inner ring area inside the screen 3 particle distribution bin, and the second screen 3 is located in the outer ring area inside the screen 3 particle distribution bin. The mesh size of the first screen 3 is higher than that of the second screen 3. This is the prior art and will not be elaborated on here.

[0023] Please see Figure 1-3 This utility model discloses a quartz sand purification device. An extension rod 4 is fixedly installed at the lower part of the sprayer 2. When the sprayer 2 rotates, it drives the extension rod 4 to rotate. A material-pushing component is arranged in a ring array on the side wall of the extension rod 4. The material-pushing component is located inside the screen 3. The material-pushing component rotates with the rotation of the extension rod 4, pushing and rotating the coarse material that falls to the bottom of the screen 3. Then, under the action of centrifugal force, it moves towards the side wall of the screen 3 and is then screened out.

[0024] The feeding assembly includes a pusher plate 5 fixedly installed in the extension rod 4. When the pusher plate 5 rotates, it pushes the coarse material to move. The pusher plate 5 extends horizontally at the bottom of the screen 3 to facilitate the movement of the coarse material.

[0025] The other end of the pusher plate 5 is provided with a feeding plate 6. The material pushed by the pusher plate 5 moves along the end face of the feeding plate 6. The feeding plate 6 extends inclinedly on the inner side of the screen 3. The coarse material moves inclined upward to the side wall of the screen 3 and is then screened out.

[0026] Both the pusher plate 5 and the feed plate 6 are inclined, and the side with an angle greater than 90 degrees between the inclined end face and the screen 3 faces the direction of rotation of the sprayer 2. As the pusher plate 5 and the feed plate 6 rotate, when the coarse material moves on the inclined end face of the pusher plate 5 and the feed plate 6, the excess coarse material falls off along the end face of the pusher plate 5 and the feed plate 6 with an angle greater than 90 degrees, and there will be no situation where the coarse material accumulates on one side of the pusher plate 5 and the feed plate 6.

[0027] Both the pusher plate 5 and the feed plate 6 are sheet-shaped. The sheet shape can push coarse materials, and it uses less material and has a low cost. In addition, there is a gap between them and the screen 3 to avoid friction between them and the screen 3 when they are selected.

[0028] In summary, when using this quartz sand purification device, the power supply is turned on, and the particle size distribution bin drive device and the sprayer 2 drive device are started. The quartz sand to be purified is fed into the device at a constant speed through the discharge pipe 1. The material enters the sprayer 2 through the discharge pipe 1 and is evenly sprayed into the particle size distribution bin of the screen 3 by the sprayer 2. When the sprayer 2 rotates, it drives the extension rod 4 and the feeding component to rotate synchronously. The pusher plate 5 horizontally pushes the coarse material falling to the bottom of the screen 3, so that it generates centrifugal force with rotation. The feeding plate 6 tilts to guide the coarse material to move upward to the side wall of the screen 3. Through the screening action of the screen 3, the quartz sand (high-purity sand) that meets the particle size requirements passes through the screen 3 and falls into the high-purity sand discharge bin 7, while the coarse sand that does not pass through falls into the coarse sand discharge bin 8.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
