[0002] Silicon carbide, also known as corundum grit or refractory sand, has the molecular formula SiC. Its hardness lies between that of corundum and diamond, while its mechanical strength is higher than that of corundum. It is resistant to high temperatures, wear, thermal shock, chemical corrosion, radiation, and exhibits good electrical and thermal conductivity. Besides being used as an abrasive, it is widely used in metallurgy, chemical engineering, ceramics, aerospace, and other fields. Due to its low natural content, silicon carbide is primarily artificially produced. A common method involves mixing quartz sand with coke, utilizing the silica and petroleum coke, adding salt and sawdust, and heating the mixture in an electric furnace to approximately 2000°C. After undergoing various chemical processes, silicon carbide powder is obtained.

[0023] The middle part of the air outlet pipe 102 is fixedly connected to the connection box 2, and the inner wall of the connection box 2 is fixedly connected to the filter plate 201. The inner wall of the air outlet pipe 102 on the left side of the connection box 2 is fixedly connected to the servo motor 202. The output end of the servo motor 202 is fixedly connected to the rotating shaft 203, and the rotating shaft 203 passes through the filter plate 201. The fan blade 204 is fixedly connected to the side wall of the rotating shaft 203 on the left side of the filter plate 201. The cleaning plate 205 is fixedly connected to the side wall of the rotating shaft 203 on the right side of the filter plate 201, and the cleaning plate 205 is in contact with the surface of the filter plate 201.

[0024] A water tank 206 is fixedly connected to the top of the air outlet pipe 102 above the connection box 2, and a collection box 207 is clamped to the bottom of the connection box 2;

[0025] It should be noted that: when the servo motor 202 is turned on, the servo motor 202 drives the rotating shaft 203 to rotate, and the rotating shaft 203 drives the fan blades 204 to rotate to generate wind force, sucking air from the feed pipe 101 and then discharging it from the air outlet pipe 102. When the feed pipe 101 is used to add materials, the dust of the raw materials in the inner cavity of the feed pipe 101 will be sucked into the inner cavity of the furnace body 1 and then discharged from the air outlet pipe 102, and when the furnace body 1 smelts silicon carbide, the exhaust gas generated will also be discharged from the air outlet pipe 102, and the filter plate 201 set in the inner cavity of the connecting box 2 can filter out all the dust and impurities in the exhaust gas, so that they adhere to the surface of the filter plate 201, and while the rotating shaft 203 rotates, the rotating shaft 203 will also drive the cleaning plate 205 to rotate, and the cleaning plate 205 will scrape the dust off the surface of the filter plate 201 and enter the inner cavity of the collection box 207 for collection.

[0026] Reference Figure 1-4 A partition is fixedly connected to the middle of the inner wall of the water tank 206, a sliding plate 3 is slidably connected between the partition and the water tank 206, and a spring 301 is fixedly connected between the sliding plate 3 and the inner wall of the water tank 206;

[0027] The bottom of the sliding plate 3 is fixedly connected to a connecting column 302, and the connecting column 302 extends to the inner cavity of the air outlet pipe 102. The bottom end of the connecting column 302 above the fan blade 204 is fixedly connected to a collision block 303;

[0028] The bottom of the water tank 206 on the right side of the partition is fixedly connected to an atomizing port 304, and the top of the water tank 206 is fixedly connected to a water inlet pipe 305, and the inner cavities of the atomizing port 304 and the water inlet pipe 305 are both provided with a one-way valve;

[0029] It should be noted that when the rotating shaft 203 drives the fan blade 204 to rotate, the fan blade 204 will collide with the collision block 303, so that the collision block 303 drives the sliding plate 3 to slide upward toward the inner cavity of the water tank 206 through the connecting column 302. At the same time, the spring 301 is squeezed to generate a rebound force. At this time, the water in the inner cavity of the water tank 206 is squeezed and sprayed out from the atomization port 304, quickly degrading the dust in the inner cavity of the air outlet pipe 102 and the impurities in the exhaust gas, and then flows into the collection box 207. cavity, and when the fan blade 204 is away from the collision block 303, under the action of the rebound force of the spring 301, the collision block 303 returns to its original position, waiting for the next collision with the fan blade 204, so that the atomizing port 304 can continue to spray water to reduce dust, wherein the atomizing port 304 and the inner cavity of the water inlet pipe 305 are both provided with a one-way valve, so that the water inlet pipe 305 can only take in water and air, and the atomizing port 304 can only spray water, thereby ensuring that the water tank 206 can always use the atomizing port 304 to spray water.

[0030] Reference Figure 1-4 , the bottom of the collision block 303 is set to be arc-shaped, and the collision block 303 and the fan blade 204 can fit together;

[0031] It should be noted that the arrangement of the collision block 303 allows the collision block 303 to slide upward when the fan blade 204 collides with the collision block 303, thereby preventing the fan blade 204 and the collision block 303 from being stuck to each other.

[0032] Operation method: Turn on the servo motor 202, the servo motor 202 drives the rotating shaft 203 to rotate, and the rotating shaft 203 drives the fan blades 204 to rotate to generate wind force, sucking air from the feed pipe 101 and then discharging it from the air outlet pipe 102. When the feed pipe 101 is used to add materials, the dust of the raw materials in the inner cavity of the feed pipe 101 will be sucked into the inner cavity of the furnace body 1 and then discharged from the air outlet pipe 102. When the furnace body 1 smelts silicon carbide, the exhaust gas generated will also be discharged from the air outlet pipe 102. The filter plate 201 provided in the inner cavity of the connecting box 2 can filter out all the dust and impurities in the exhaust gas and make them adhere to the surface of the filter plate 201. When the rotating shaft 203 rotates, the rotating shaft 203 also drives the cleaning plate 205 to rotate. The cleaning plate 205 will scrape the dust from the surface of the filter plate 201 and enter the inner cavity of the collection box 207 for collection.

[0033] When the rotating shaft 203 drives the fan blades 204 to rotate, the fan blades 204 will collide with the collision block 303, so that the collision block 303 drives the sliding plate 3 to slide upwards in the inner cavity of the water tank 206 through the connecting column 302, and at the same time the spring 301 is squeezed to generate a rebound force. At this time, the water in the inner cavity of the water tank 206 is squeezed and sprayed out from the atomization port 304, quickly degrading the dust in the inner cavity of the air outlet pipe 102 and the impurities in the exhaust gas, and then flows into the inner cavity of the collection box 207, and when the fan blades 204 are away from the collision block 303, under the action of the rebound force of the spring 301, the collision block 303 returns to its original position, waiting for the next collision with the fan blades 204, so that the atomization port 304 can continue to spray water to reduce dust.
