[0002] Semiconductor-grade quartz glass crucibles require high purity. To reduce costs while maintaining the purity of the quartz crucible, composite quartz crucibles are generally used. The outer lining of the composite quartz crucible uses high-purity natural quartz sand, but the inner surface containing the molten silicon uses high-purity synthetic quartz sand. First, high-purity natural quartz sand is added to a mold, rotated, and shaped using a forming rod. Then, high-purity synthetic quartz sand is added and shaped again.

[0003] Quartz sand is an important component of building materials, used in areas such as interior design, and in the production of everyday items like thermos cups, automotive glass, and cement boards. However, the utilization of quartz sand is inseparable from the processing of quartz ore. As the processing of quartz ore becomes more refined, the quality of products made from quartz sand will also improve. Quartz sand has a large volume after collection and is powdered after crushing and grinding.

[0004] Currently, the production process of quartz sand lacks a filtration structure for the added quartz sand, resulting in large pieces of material in the quartz sand not being fully melted, and the flow rate of the added material cannot be flexibly selected according to the melting of the quartz sand. Therefore, it is necessary to propose a feeding device for quartz sand molding to solve the above-mentioned problems. Utility Model Content

[0007] A fixed plate is installed inside the feeding chamber.

A turntable is set below the fixed plate, and a notch is opened through the outer wall of the turntable. A second motor with its output end fixedly connected to the turntable is installed on the lower surface of the feeding chamber.

[0008] To allow for flexible selection of different discharge flow rates for the filtered quartz sand, the preferred feeding device for quartz sand molding according to this utility model has two mounting plates fixedly connected to both the front and rear sides of the outer wall of the feeding chamber. A threaded rod is rotatably connected between the two front mounting plates. A third motor with its output end fixedly connected to the threaded rod is installed on the outer wall of the right front mounting plate. A fixing frame fixedly connected to the filter chamber is threadedly connected to the outer wall of the threaded rod. A sliding rod that is slidably connected to the heating chamber through the fixing frame is fixedly connected between the two rear mounting plates.

[0009] In order to facilitate the smooth entry of quartz sand into the furnace, as a preferred embodiment of the feeding device for quartz sand molding of this utility model, the upper end face of the feeding chamber is provided with feeding ports on both the left and right sides, and the lower end face of the feeding chamber is connected to two feeding channels.

[0010] In order to filter quartz sand into the filter chamber, as a preferred feeding device for quartz sand molding according to this utility model, the upper end face of the filter chamber is open, and the lower end face of the filter chamber is connected to a discharge pipe that contacts the upper end face of the feeding chamber and has a valve installed on its outer wall.

[0011] In order to connect the feeding chamber to the furnace via a connecting frame, as a preferred embodiment of the feeding device for quartz sand molding of this utility model, the outer wall of the feeding chamber is fixedly connected to a connecting frame.

[0012] In order to control the normal operation of the first motor, the second motor, and the third motor, as a preferred feeding device for quartz sand molding according to this utility model, a controller is installed on the outer wall of the filter chamber, and the first motor, the second motor, and the third motor are all electrically connected to the controller.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This invention first causes the paddle to rotate along the inner wall of the filter plate, agitating the quartz sand on the filter plate and filtering out large pieces of material in the quartz sand, thereby preventing large pieces of material from affecting the smelting efficiency of the furnace.

[0015] Secondly, aligning the notch with the large mesh allows the quartz sand on the fixed plate to exit through the notch via the large mesh. Aligning the notch with the small mesh allows the quartz sand on the fixed plate to exit through the notch via the small mesh. By setting large and small meshes, the system can accommodate quartz sand of different particle sizes and densities, and the feeding flow rate can be flexibly selected, thereby improving production efficiency.

[0020] Please see Figures 1 to 3 A feeding device for quartz sand molding includes a feeding chamber 2, a filter chamber 1 that can move left and right is provided above the feeding chamber 2, a filter plate 101 is installed inside the filter chamber 1, a lever 103 that contacts the filter plate 101 is rotatably connected inside the filter chamber 1, and a first motor 102 whose output end is fixedly connected to the lever 103 is installed on the outer wall of the filter chamber 1.

[0021] The feeding chamber 2 is equipped with a fixed plate 201. The left side of the upper surface of the fixed plate 201 has multiple evenly distributed large mesh holes 202, and the right side of the upper surface of the fixed plate 201 has multiple evenly distributed small mesh holes 203. A turntable 204 is provided below the fixed plate 201. A notch 205 is provided through the outer wall of the turntable 204. A second motor 206 with its output end fixedly connected to the turntable 204 is installed on the lower surface of the feeding chamber 2.

[0022] In this embodiment: Quartz sand is poured into the filter plate 101 in the filter chamber 1, and the first motor 102 is started at the same time, so that the first motor 102 drives the lever 103 to rotate, causing the lever 103 to rotate along the inner wall of the filter plate 101. In this way, the quartz sand on the filter plate 101 can be moved by the lever 103 to filter the quartz sand, so that large pieces of material in the quartz sand are filtered out, thereby avoiding large pieces of material from affecting the smelting of the furnace.

[0023] Secondly, the filtered quartz sand can be moved left and right to select different flow rates for feeding. The second motor 206 is started, causing the turntable 204 to rotate, aligning the notch 205 with the large mesh 202. When the filtered quartz sand falls onto the large mesh 202 on the left side of the fixed disc 201, it can then be discharged through the notch 205. The second motor 206 is then started, causing the turntable 204 to rotate, aligning the notch 205 with the small mesh 203. When the filtered quartz sand falls onto the small mesh 203 on the right side of the fixed disc 201, it can then be discharged through the notch 205. By setting the large mesh 202 and small mesh 203, different particle sizes and densities of quartz sand can be accommodated, and the feeding flow rate can be flexibly selected, thereby improving production efficiency.

[0024] As a technical optimization of this utility model, two mounting plates are fixedly connected to the front and rear sides of the outer wall of the feeding chamber 2. A threaded rod 3 is rotatably connected between the two front mounting plates. A third motor 301 with its output end fixedly connected to the threaded rod 3 is installed on the outer wall of the front right mounting plate. A fixing frame 302 fixedly connected to the filter chamber 1 is threadedly connected to the outer wall of the threaded rod 3. A slide rod that is slidably connected to the feeding chamber 2 through the fixing frame 302 is fixedly connected between the two rear mounting plates.

[0025] In this embodiment: the third motor 301 is started, which drives the threaded rod 3 to rotate, causing the fixed frame 302 to move the filter chamber 1 left and right. The fixed frame 302 can be limited by the sliding rod, so that the filtered quartz sand can flexibly select different discharge flow rates.

[0026] As a technical optimization of this utility model, the upper end face of the feeding chamber 2 is provided with feeding ports on both the left and right sides, and the lower end face of the feeding chamber 2 is connected to two feeding channels 207.

[0027] In this embodiment: the filtered quartz sand can be fed through two feed ports, and the feed port can be selected according to the feed flow rate. The quartz sand can be smoothly fed into the furnace through the feed channel 207.

[0028] As a technical optimization of this utility model, the upper end face of the filter chamber 1 is open, and the lower end face of the filter chamber 1 is connected to the upper end face of the feeding chamber 2, and a valve is installed on the outer wall of the discharge pipe 104.

[0029] In this embodiment: the upper end face of the filter chamber 1 has an open structure, so quartz sand can be poured into the filter chamber 1 for filtration. By opening the discharge pipe 104, the filtered quartz sand can fall into the feeding chamber 2.

[0030] As a technical optimization of this utility model, a connecting frame 5 is fixedly connected to the outer wall of the feeding chamber 2.

[0031] In this embodiment, the connecting frame 5 facilitates the connection between the feeding chamber 2 and the furnace.

[0032] As a technical optimization of this utility model, a controller 4 is installed on the outer wall of the filter chamber 1, and the first motor 102, the second motor 206, and the third motor 301 are all electrically connected to the controller 4.

[0033] In this embodiment, the controller 4 can control the first motor 102, the second motor 206, and the third motor 301 to work normally.

[0034] Working principle: First, quartz sand is poured into the filter plate 101 in the filter chamber 1. At the same time, the first motor 102 is started, which drives the lever 103 to rotate, causing the lever 103 to rotate along the inner wall of the filter plate 101. In this way, the quartz sand on the filter plate 101 can be moved by the lever 103 to filter the quartz sand.

[0035] Next, start the third motor 301, which drives the threaded rod 3 to rotate, causing the fixed frame 302 to move the filter chamber 1 to the left until the discharge pipe 104 is located at the feed inlet on the left side of the feeding chamber 2. Then, start the second motor 206, which drives the turntable 204 to rotate, causing the notch 205 to align with the large mesh 202. This allows the filtered quartz sand to fall through the discharge pipe 104 onto the large mesh 202 on the left side of the fixed plate 201, thus allowing the quartz sand on the fixed plate 201 to exit through the large mesh 202 and the notch 205. The filter chamber 1 is moved to the right, and the discharge pipe 104 is located on the right feed port. The second motor 206 is started, which drives the turntable 204 to rotate, causing the notch 205 to align with the small mesh 203. When the filtered quartz sand falls onto the small mesh 203 on the right side of the fixed plate 201, the quartz sand on the fixed plate 201 can then be discharged through the notch 205 via the small mesh 203. Furthermore, by setting the large mesh 202 and the small mesh 203, it is possible to accommodate quartz sand with different particle sizes and densities. At the same time, the feed flow rate can be flexibly selected, thereby improving production efficiency.
