[0002] Silicon carbide is an inorganic substance made from quartz sand, petroleum coke, sawdust and other raw materials through high-temperature smelting in a resistance furnace. Due to the small particle size, high surface energy and easy agglomeration of silicon carbide powder, secondary particles are formed, which makes it difficult to play the advantages of ultrafine powder, and ultimately affects the excellent performance of the finished product. Therefore, it is necessary to modify the surface of silicon carbide powder to make it have good dispersibility. In the process of silicon carbide modification, silicon carbide modification equipment is needed.

[0003] A Chinese patent document with publication number CN220992099U discloses a pickling tank for silicon carbide micropowder production, comprising a tank body and a first stirring component; by setting the first stirring component, the first motor is started during use to rotate the rotating tube, and the rotation of the rotating tube drives the two stirring plates to rotate, so that the material and the strong acid in the tank body can be initially stirred, in this case, the reaction time of the two can be initially accelerated, and by setting the toggle component, the toggle component is started during use to make the second gear swing left and right, and the second gear swings left and right to drive the cross stirring plate to swing left and right, in this case, the material and the strong acid in the tank body can be further stirred.

[0004] The disadvantage of the above-disclosed solution is that the third motor drives the fan-shaped gear to rotate, and the rotation of the fan-shaped gear drives the cross stirring plate to move through the second gear, and cooperates with the action of the torsion spring to drive the cross stirring plate to swing left and right, so that only the material at the bottom of the tank body can be stirred left and right, resulting in a small stirring range for the material at the bottom of the tank body, insufficient stirring, and reduced pickling efficiency of the material and strong acid.

The bottom of the first rotating shaft passes downward through the toothed ring cover and is rotatably connected to the toothed ring cover. A sun gear is fixedly sleeved at the bottom of the first rotating shaft. A ring gear is fixedly arranged at the bottom of the toothed ring cover. An L-shaped connecting plate is fixedly arranged at the bottom of the ring gear. A sliding block is slidably arranged at the bottom of the L-shaped connecting plate. A second rotating shaft is rotatably arranged on the sliding block. A planet gear is fixedly sleeved at the top of the second rotating shaft.

[0010] Further, fixing legs are fixedly arranged on the tank body, and a chassis is fixedly arranged at the bottom of the fixing legs.

[0011] Compared with the prior art, the beneficial effects of the present utility model are:

[0012] A planet gear is fixedly sleeved at the top of the second rotating shaft. The planet gear meshes with the ring gear and the sun gear respectively. A second stirring plate is fixedly arranged on the second rotating shaft. When the motor is started, the motor drives the first rotating shaft to rotate.

An electromagnetic valve 17 is installed on the discharge pipe 16, and the electromagnetic valve 17 controls the discharge of the discharge pipe 16. Fixed support legs 18 are symmetrically and fixedly installed on the outer side of the tank body 1. The bottom of the fixed support legs 18 is fixedly installed with a chassis 19, which plays a role in supporting and stabilizing the tank body 1.

[0019] A motor 3 is fixedly installed at the center of the top of the tank body 1. The output end of the motor 3 passes downward through the tank body 1 and is fixedly installed with a first rotating shaft 4. Stirring plates 5 are symmetrically and fixedly installed on the outer periphery of the first rotating shaft 4. A fixed frame 10 is fixedly installed at the bottom inside the tank body 1. The fixed frame 10 is composed of two L-shaped rods. The two L-shaped rods are symmetrically and fixedly installed on the bottom wall inside the tank body 1. The tops of the two L-shaped rods of the fixed frame 10 are fixedly installed with a gear ring cover 6. The gear ring cover 6 is a cylindrical structure with an opening at the bottom.

[0020] The bottom of the first rotating shaft 4 passes downward through the ring gear cover 6 and is rotatably installed in cooperation with the ring gear cover 6. A sun gear 11 is fixedly sleeved on the bottom of the first rotating shaft 4. A ring gear 7 is fixedly installed at the bottom of the ring gear cover 6. An L-shaped connecting plate 8 is fixedly installed at the bottom of the ring gear 7, and the cross-section of the L-shaped connecting plate 8 is L-shaped. A sliding block 13 is slidably installed at the bottom of the L-shaped connecting plate 8. At the top of the horizontal part of the L-shaped connecting plate 8, a T-shaped guide rail 9 is fixedly installed along its circumference. A T-shaped chute is formed on the sliding block 13, and the T-shaped guide rail 9 is slidably installed in cooperation with the T-shaped chute on the sliding block 13 to prevent the sliding block 13 from detaching from the T-shaped guide rail 9, and the T-shaped guide rail 9 plays a role in guiding the sliding of the sliding block 13.

[0021] A second rotating shaft 14 is rotatably installed at the end of the sliding block 13 away from the L-shaped connecting plate 8. The second rotating shaft 14 is arranged vertically. A planetary gear 12 is fixedly sleeved on the top of the second rotating shaft 14. The planetary gear 12 meshes with the ring gear 7 and the sun gear 11 respectively. A plurality of second stirring plates 15 are fixedly installed on the second rotating shaft 14. The plurality of second stirring plates 15 are arranged in a circumferential array, and the fixing frame 10 does not interfere with the rotation of the second stirring plates 15.

[0022] The working principle of a device for silicon carbide modification provided by the present utility model is as follows:

[0023] During use, first, the acidic liquid is injected into the tank body 1 through the feed port 2, and then the silicon carbide powder is put into the tank body 1 through the feed port 2. The motor 3 is started, and the motor 3 drives the first rotating shaft 4 to rotate. The first rotating shaft 4 drives the first stirring plate 5 to rotate, and the first stirring plate 5 rotates to initially stir the acidic liquid and the silicon carbide powder inside the tank body 1.

[0024] At the same time, when the first rotating shaft 4 rotates, it will also drive the sun gear 11 to rotate. The sun gear 11 drives the planetary gear 12 to rotate. The planetary gear 12 drives the second rotating shaft 14 to rotate self. The self-rotation of the second rotating shaft 14 drives the second stirring plates 15 to rotate around the axis of the second rotating shaft 14. The planetary gear 12 meshes with the ring gear 7 at the same time and rotates around the axis of the first rotating shaft 4. The planetary gear 12 drives the second rotating shaft 14 to revolve around the axis of the first rotating shaft 4. The second rotating shaft 14 drives the sliding block 13 to slide along the T-shaped guide rail 9 at the same time, so that the planetary gear 12 will not disengage from the sun gear 11 during the rotation process.

[0025] The second rotating shaft 14 also drives the second stirring plates 15 to revolve around the axis of the first rotating shaft 4 at the same time. Thus, while the second stirring plates 15 rotate around the second rotating shaft 14, they also revolve around the axis of the first rotating shaft 4, increasing the stirring range of the second stirring plates 15, further stirring the acidic liquid and the silicon carbide powder at the bottom of the tank body 1, shortening the reaction time between the two, and improving the efficiency of pickling and modification of the silicon carbide powder. After pickling is completed, the electromagnetic valve 17 is controlled to discharge through the discharge pipe 16.

[0026] Although embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principle and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
