Description

Technical Field

[0001] The invention relates to the technical field of silicon carbide production, and in particular to a processing device and method for high-purity silicon carbide synthetic powder. Background Art

[0002] Silicon carbide powder refers to micron-sized silicon carbide powder that is ultra-finely crushed and graded by equipment. Due to the incomplete reaction of raw materials in the production process of silicon carbide, as well as the influence of processing equipment and the external environment, impurities such as free carbon will be generated. When a tube furnace is used to remove carbon from silicon carbide powder, air is introduced, so a small amount of silicon dioxide will be generated during the decarbonization. This is because during the synthesis, excess silicon will combine with oxygen in the air to form silicon dioxide. The presence of silicon dioxide is not conducive to the growth of silicon carbide crystals, so people use acid washing to dissolve the silicon dioxide impurities in silicon carbide powder.

[0003] For example, a pickling device for silicon carbide powder production with announcement number CN212669221U, the coordinated use of an overdilution box, an acid-resistant pump, an acid inlet pipe, a water suction pump, a liquid outlet pipe, a water tank, a submersible pump, a water outlet pipe, a first water supply pipe and a second water supply pipe can effectively collect and treat the solution after pickling, effectively avoid the pollution caused by the direct discharge of the acidic solution into the environment, and greatly improve the cleanliness of the device. However, in actual use, as the pickling of silicon carbide powder proceeds, the acid solution reacts continuously with impurities, and the concentration of the acid solution decreases, and it is necessary to add acid solution. If the acid solution is added directly during the process of adding the acid solution, the addition is not uniform, and violent reactions are likely to occur locally, and it is easy to cause acid splashing. The operation has certain risks. If the acid solution cannot be added evenly, the local concentration of the pickling solution is too high, resulting in poor cleaning effect, and over-pickling is prone to occur, affecting the quality of pickling, and there are certain usage defects.

[0004] Therefore, we propose a processing device and method for high-purity silicon carbide synthetic powder in order to solve the above-mentioned problems. Summary of the invention

[0062] Working principle: When using the high-purity silicon carbide synthetic powder processing equipment, first, according to Figure 1-Figure 9As shown, when the silicon carbide powder is pickled, the silicon carbide powder is added to the water-permeable frame 102, and then the water-permeable frame 102 is hoisted into the pickling tank 1 by a hoisting device, a certain amount of acid is added to the pickling tank 1, and a pH meter is provided in the pickling tank 1, and then the driving motor 204 can be started to drive the first pulley 205 to rotate, and then the second pulley 206 is driven to rotate by the belt, so that the rotating shaft 203 is rotated and connected, and after the rotating shaft 203 rotates, the stirring blade 207 can be driven to rotate, and the powder can be stirred so that the impurities in the powder can react evenly with the acid, and the pH value of the acid is monitored by the pH meter, and then when it is necessary to add acid, the acid can be added to the adding bucket 212, and the acid can enter the adding pipe 210, and the acid can leak out through the second telescopic hose 221, and the rotating shaft 203 can be driven by the rotating frame 209 during the rotation process. The adding pipe 210 rotates, and the rotating frame 209 can drive the arc block 218 to slide inside the annular groove 217 to support and limit the position during the circular rotation. The rotating frame 209 can drive the rotating gear 215 to rotate in a circular manner. After the rotating gear 215 rotates, it can drive the rotating shaft 222 to rotate, so that the column block 224 on the rotating rod 223 rotates in a circular manner. After the column block 224 rotates in a circular manner, it can drive the movable frame 225 to reciprocate up and down through the sliding connection with the movable frame 225. After the movable frame 225 moves, it can drive the movable plate 231 to reciprocate through the connecting frame 227, and then drive the rotating rod 229 to reciprocate through the meshing of the tooth plate 232 and the driven gear 230, so that the installation pipe 220 and the second telescopic hose 221 can swing back and forth, so that the second telescopic hose 221 can swing back and forth while the adding pipe 210 rotates in a circular manner;

[0063] When adding acid solution, the rotating rod 229 rotates back and forth, so that the L-shaped rod 233 can be driven to swing back and forth, so that the second telescopic hose 221 can swing together with the mounting tube 220. During the reciprocating swing of the L-shaped rod 233, the ball slides on the V-shaped plate 236. When the L-shaped rod 233 swings and is no longer vertical, the L-shaped rod 233 slides on the rotating rod 229 under the guidance of the V-shaped plate 236, and the telescopic spring 234 can be stretched. After the movement, the L-shaped rod 233 can stretch the second telescopic hose 221, so that the second telescopic hose 221 can be elongated, and then the reciprocating rotation of the rotating rod 229 can make the second telescopic hose 221 continuously extend and contract. When the water-permeable frame 102 is hoisted, the water-permeable frame 102 is lifted and moved to the top of the pickling tank 1, and the water-permeable frame 102 is controlled to move downward, so that the inclined block 301 and the centering block 302 are fitted together, so that the left and right positions of the water-permeable frame 102 can be adjusted. The locating pin 306 can be passed through the mounting hole 305 and the locating hole 307 to position the water permeable frame 102. The rotating plate 310 can be pushed and rotated so that the rotating plate 310 slides on the column rod 309 and compresses the return spring 311. The locating block 312 on the rotating plate 310 is aligned with the locating groove 313 on the mounting block 308. The rotating plate 310 can be released and the locating block 312 is engaged with the locating groove 313 under the action of the return spring 311. The locating pin 306 can be positioned. The water permeable frame 102 can be positioned by the locating pin 306 to avoid accidental movement of the water permeable frame 102 during the subsequent pickling process, thereby improving the stability of the pickling work.
