[0002] Silicon carbide is a high-performance inorganic non-metallic material, widely used in ceramics, refractory materials, abrasives and other fields. In the production process of silicon carbide, quartz sand is one of the raw materials, and its purity, particle size and cleanliness have a crucial impact on the performance of silicon carbide. If the quartz sand contains impurities or oil and other pollutants, it will cause defects such as pores and inclusions in the silicon carbide product, thereby reducing the quality and performance of silicon carbide.

[0003] In the prior art, a quartz sand cleaning device for producing silicon carbide proposed by announcement number CN214600700U includes a bracket, a lower hopper is fixedly installed inside the bracket, a cleaning bin is fixedly connected to the bottom of the lower hopper, a stirring roller located inside the cleaning bin is fixedly installed on the front of the bracket, a pad is fixedly installed on the inner bottom of the cleaning bin, a discharge plate is fixedly installed on the left side of the cleaning bin, a separation bin is fixedly installed on the left side of the cleaning bin and at the bottom of the discharge plate, a sieve plate is fixedly installed inside the separation bin, a sleeve is fixedly installed on the top of the sieve plate, a vibrator is fixedly installed inside the sleeve, a shock-absorbing pad is fixedly connected to the top of the sleeve, and a buffer spring is fixedly connected to the top of the shock-absorbing pad.

DETAILED DESCRIPTION

[0026] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0027] Example:

[0028] Reference Figure 1 - Figure 6 The utility model discloses a quartz sand cleaning device for producing silicon carbide, comprising a cleaning bin 1, a feed port 2 and a discharge port 3, wherein the feed port 2 and the discharge port 3 are both arranged on the outer peripheral wall of the cleaning bin 1, a driving motor 4 is eccentrically connected to the side of the cleaning bin 1, an output shaft of the driving motor 4 extends into the cleaning bin 1, a cleaning net cylinder 5 is fixedly connected to the output shaft of the driving motor 4, a plurality of grooves 6 are arranged on the outer peripheral wall of the cleaning net cylinder 5, a rubbing roller 8 is rotatably connected to the groove 6 through a transmission member 7, and an anti-slip member 9 is arranged on the outer peripheral wall of the rubbing roller 8.

[0029] In this embodiment, when in use, unwashed quartz sand is poured from the feed port 2, and the drive motor 4 is started. At the same time, a proper amount of water is injected into the cleaning chamber 1, and the water level should be lower than the position of the discharge port 3. The drive motor 4 will drive the rotation of the cleaning net cylinder 5, and at the same time, it will also drive the rotation of the rubbing roller 8, and then drive the rotation of the rubbing roller 8 through the transmission member 7 provided;

[0030] After the quartz sand enters the cleaning bin 1, it will first be soaked in water, and then the rotation of the rubbing roller 8 will drive the quartz sand to move toward the discharge port 3. Because the driving motor 4 is eccentrically arranged on the side of the cleaning bin 1, the cleaning mesh cylinder 5 is also eccentrically arranged, so that when the quartz sand is pushed toward the discharge port 3, the distance between the inner wall of the cleaning bin 1 and the outer wall of the cleaning mesh cylinder 5 will gradually decrease, and then with the rotation of the rubbing roller 8, the rubbing roller 8 and the quartz sand will rub against each other to achieve a rubbing effect, and then the dust and impurities stuck on the quartz sand can be removed by rubbing, thereby improving the cleanliness of the cleaning. After the quartz sand is rubbed and cleaned, the quartz sand is pushed out from the discharge port 3.

[0031] In a further preferred embodiment of the present invention, Figure 2-5As shown, the transmission member 7 includes a positioning cover 10, and the positioning cover 10 is fixedly installed on the cleaning chamber 1 on one side of the driving motor 4. The axis of the positioning cover 10 is on the same straight line as the axis of the cleaning net cylinder 5. The cleaning chamber 1 is provided with an annular groove 11 at the positioning cover 10, and a dynamic sealing ring 12 is rotatably connected in the annular groove 11. The end of the kneading roller 8 close to the positioning cover 10 is fixedly connected to a transmission rod 13, and the end of the transmission rod 13 passes through the dynamic sealing ring 12 and extends into the positioning cover 10.

[0032] In this embodiment, a positioning cover 10 is fixedly installed on the side of the cleaning bin 1, and an annular groove 11 is opened at the cleaning bin 1 at the positioning cover 10, and the annular groove 11 is in a connected state with the positioning cover 10. With the connection of the positioning cover 10, the cleaning bin 1 is located in the middle of the annular groove 11 and the groove side wall will not fall off, so the driving motor 4 can still drive the cleaning net cylinder 5 to rotate. In order to prevent the water inside the cleaning bin 1 from entering the positioning cover 10, the dynamic sealing ring 12 is rotatably connected in the annular groove 11 and is in a dynamic sealing state. In addition, a transmission rod 13 is provided that passes through the dynamic sealing ring 12 and extends into the positioning cover 10, and the dynamic sealing ring 12 and the transmission rod 13 are also in a dynamic sealing state;

[0033] Therefore, when the driving motor 4 drives the cleaning net cylinder 5 to rotate, it will also drive the rubbing roller 8 to perform circular motion, and at the same time will drive the dynamic sealing ring 12 to rotate. The dynamic sealing ring 12 can act as a seal, and by driving the rubbing roller 8 to perform circular motion, when the rubbing roller 8 gradually approaches the discharge port 3, the rubbing roller 8 squeezes and rubs the quartz sand, thereby achieving the effect of rubbing and cleaning.

[0034] In a further preferred embodiment of the present invention, Figure 4 As shown, a transmission gear 14 is fixedly connected to the end of the transmission rod 13 , and an inner gear ring 15 is fixedly connected to the inner peripheral wall of the positioning cover 10 , and the inner gear ring 15 is meshed with the transmission gear 14 .

[0035] In this embodiment, the transmission gear 14 and the inner gear ring 15 are set, when the kneading roller 8 makes a circular motion, the transmission gear 14 will also be driven to make a circular motion through the transmission rod 13, and the inner gear ring 15 and the transmission gear 14 are meshed with each other, so when the transmission gear 14 makes a circular motion, the transmission gear 14 will be driven to rotate, and then the kneading roller 8 will be driven to rotate, so when kneading the quartz sand, the quartz sand is further rubbed by the rotation of the kneading roller 8, which can further knead the quartz sand, thereby improving the cleanliness of the quartz sand during cleaning.

[0036] In a further preferred embodiment of the present invention, Figure 6As shown, the anti-slip member 9 includes a plurality of mounting holes 16, and the mounting holes 16 are provided on the rubbing roller 8, and the end side wall in the mounting hole 16 is fixedly connected with a return spring 17, and the end of the return spring 17 is fixedly connected with an anti-sliding block 18, and the end of the anti-sliding block 18 is arc-shaped.

[0037] In this embodiment, when the kneading roller 8 rotates in a circular motion, it will drive the anti-sliding block 18 to move in a circular motion, thereby moving and rubbing the quartz sand, avoiding the rotation of the kneading roller 8 causing insufficient friction between the quartz sand and reducing the cleaning efficiency of the kneading.

[0038] In a further preferred embodiment of the present invention, Figure 2 As shown, a water inlet hole 19 is opened in the middle of the side of the cleaning bin 1, and a docking pipe 20 is fixedly connected in the water inlet hole 19.

[0039] In this embodiment, the water inlet hole 19 is used to install the docking pipe 20, which can be connected to an external water pipe, so that water can be transported through the external water pipe and transported to the cleaning chamber 1 to facilitate the cleaning of the quartz sand.

[0040] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
