Technical Field
[0001] The present application relates to the technical field of powder dust removal equipment, and specifically discloses a dust removal device for silicon carbide production materials. Background Art
[0002] Silicon carbide, also known as corundum, is made from quartz sand, petroleum coke or coal coke, sawdust and other raw materials through high-temperature smelting in a resistance furnace. Silicon carbide ores also exist in nature, and this type of ore is called moissanite.
[0003] In the existing silicon carbide production process, there is a process step of crushing silicon carbide. During the crushing process of silicon carbide, water needs to be passed into the crusher to reduce the generation of silicon carbide dust and reduce the wear of the crusher. However, after the impure silicon carbide is crushed, the silicon carbide particles will also be adhered to water, and the water will also carry dust to the surface of the silicon carbide particles. In the subsequent transportation process of the silicon carbide material particles, as the silicon carbide particles dry, the volatilization of water will cause dust to adhere to the surface of the silicon carbide particles, and then generate dust in the subsequent transportation process.
[0004] Therefore, in view of this, the inventor provides a silicon carbide production material dust removal device to solve the above-mentioned problems. Utility Model Content
[0005] The utility model aims to solve the problem that in the traditional silicon carbide production process, when crushing silicon carbide, water added in the crushing process will carry dust and adhere to the surface of the crushed silicon carbide particles, thereby generating dust in the subsequent transportation and processing of the silicon carbide particles.
[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a silicon carbide production material dust removal device, including a drying barrel, a feed port arranged at one end of the drying barrel, a discharge port arranged at one end of the drying barrel, a feeding structure arranged in the drying barrel for conveying silicon carbide particles from the feed port to the discharge port, and a driving structure for driving the feeding structure, a plurality of air inlets are opened at the bottom end of the drying barrel, the bottom end of the drying barrel is connected to an air inlet pipe barrel that wraps the air inlet and is used to introduce hot air, a plurality of air outlets are opened at the top end of the drying barrel, and the top end of the drying barrel is connected to an air outlet pipe barrel that wraps the air outlet and is used to export hot air.
[0007] Furthermore, the drying barrel is arranged to be inclined, and the inclination direction is downward from the feed inlet toward the discharge outlet.
[0008] Furthermore, the feeding structure comprises a rotating rod coaxially arranged in the drying barrel and driven to rotate by the driving structure, a plurality of material shifting rings coaxially fixed to the rotating rod, and a plurality of material shifting plates circumferentially fixed to the material shifting rings.
[0009] Furthermore, the end surface of the material-diverting plate is inclined toward the material feed port.
[0010] Furthermore, a guide and dust removal structure for separating dust is provided in the air outlet pipe barrel.
[0011] Furthermore, the air guide and dust removal structure includes an arc-shaped guide plate fixedly connected to the inner end of the air outlet duct barrel, an arc-shaped dust removal plate coaxially fixedly connected to the inner end of the air outlet duct barrel inside the arc-shaped guide plate, and a sealing plate respectively fixed between the two ends of the arc-shaped guide plate and the arc-shaped dust removal plate. A dust filter plate is provided on the arc-shaped dust removal plate, and a gap is left between the sealing plate and the inner wall of the air outlet duct barrel for hot air to pass through.
[0012] Furthermore, the air outlet duct barrel is provided with a dust removal groove parallel to the arc-shaped dust removal plate, and the inner walls on both sides of the dust removal groove are respectively fixed with sealing gaskets that fit each other. The air outlet duct barrel is provided with a dust removal plate that slides between the sealing gaskets in the dust removal groove, and the bottom end of the dust removal plate fits with the dust filter plate.
[0013] Furthermore, a guide tube connected to the chamber between the arc-shaped dust removal plate and the arc-shaped guide plate is provided at the end of the air outlet duct barrel, and the end of the guide tube is connected to the air inlet duct barrel.
[0014] The principle and effect of this scheme are:
[0015] 1. Compared with the prior art, the utility model introduces the silicon carbide particles with water adhered to the surface after crushing into the feed port of the drying barrel, and transports them to the discharge port by the feeding structure. During the transportation process, hot air is introduced into the drying barrel from the air inlet through the air inlet duct barrel. The hot air blows through the silicon carbide particles to take away the moisture on the surface, and blows away the attached dust and blows it into the air outlet, and is discharged from the air outlet duct barrel connected to the air outlet. This solves the problem in the traditional silicon carbide production process that when the silicon carbide is crushed, the water added in the crushing process will carry the dust and adhere to the surface of the crushed silicon carbide particles, and generate dust in the subsequent transportation and processing of the silicon carbide particles.
[0016] 2. Compared with the prior art, when hot air blows over the silicon carbide particles, the utility model can also stir the silicon carbide particles in the drying barrel through the rotating rod, the material-switching ring and the material-switching plate arranged in the feeding structure to realize the turning of the materials, so as to shift the silicon carbide particles at the bottom to the surface and break up the accumulated silicon carbide particles, so that the silicon carbide particles can better exchange heat with the hot air and the dust on the surface can be blown away by the hot air. In the process of shifting the silicon carbide particles, the dust attached to the surface of the silicon carbide particles can also hit each other and fall off, and then be carried away by the hot air. At the same time, the feeding structure can also play the role of conveying the silicon carbide particles to the discharge port.
[0017] 3. Compared with the prior art, the utility model is further provided with a guide dust removal structure. The hot air containing dust enters into the chamber above the arc dust removal plate from the gap between the sealing plate and the inner wall of the air outlet duct barrel, and passes through the dust filter plate. The dust carried by the hot air remains on the dust filter plate. The filtered hot air enters into the gap between the arc dust removal plate and the arc guide plate, and passes into the air inlet duct barrel again through the guide duct to realize recycling.

A feed conduit 4 connected to the feed port is also installed at the left end of the drying barrel 1, and a discharge conduit 8 connected to the discharge port is also installed at the right end of the drying barrel 1.
[0026] The bottom of the drying barrel 1 is provided with a plurality of air inlets, and an air inlet pipe barrel 2 is installed at the bottom of the drying barrel 1 to cover the air inlets and introduce hot air. The top of the drying barrel 1 is provided with a plurality of air outlets, and an air outlet pipe barrel 3 is installed at the top of the drying barrel 1 to cover the air outlets and guide the hot air.
[0027] like Figure 2 and Figure 3 As shown, a support plate is installed on the left side of the feed conduit 4, and the driving structure is specifically a drive motor 5 installed on the support plate. The feeding structure includes a rotating rod 6 coaxially installed in the drying barrel 1, a plurality of material-pickling rings coaxially fixedly installed on the rotating rod 6 and located in the drying barrel 1, and a plurality of material-pickling plates 10 respectively fixedly installed circumferentially on the material-pickling rings. A turntable is installed at the right end of the drying barrel 1 for the right end of the rotating rod 6 to extend into and rotate inside, and the left end of the rotating rod 6 extends out of the drying barrel 1 and passes through the feed conduit 4 and is connected to the output shaft of the drive motor 5 through a coupling. When the output shaft of the drive motor 5 rotates, it will drive the rotating rod 6 to rotate synchronously.
[0028] The inner end of the material stripping plate 10 is in contact with the inner wall of the drying barrel 1, and the end faces of the material stripping plate 10 are inclined toward the feed inlet. Further, in order to be inclined toward the rotation direction, in this embodiment, Figure 3 In the direction shown, the material stripping plate 10 rotates clockwise, and the end surface of the material stripping plate 10 is inclined in the clockwise direction.
[0029] like Figure 2 and Figure 3 As shown, a guide dust removal structure for separating dust is also provided in the air outlet barrel 3. The guide dust removal structure includes an arc guide plate 12 fixedly mounted on the inner wall of the left end of the air outlet barrel 3, an arc dust removal plate coaxially fixedly mounted on the inner wall of the left end of the air outlet barrel 3 on the inner side of the arc guide plate 12, and a sealing plate respectively fixedly mounted between the arc guide plate 12 and the two ends of the arc dust removal plate. A filter groove is also provided on the arc dust removal plate, and a dust filter plate 11 is installed in the filter groove, wherein a gap is left between the sealing plate and the inner wall of the air outlet barrel 3 for hot air to pass through. Moreover, the right ends of the arc guide plate 12 and the arc dust removal plate are both flush with the right end of the air outlet barrel 3.
[0030] A dust removal groove parallel to the arc dust removal plate is also formed on the air outlet pipe barrel 3, and a sealing gasket 13 whose inner walls are fitted to each other is fixedly installed on the inner walls of both sides of the dust removal groove. In this embodiment, the sealing gasket 13 is made of high temperature resistant rubber. A dust removal plate 7 is installed on the air outlet pipe barrel 3, which slides between the sealing gaskets 13 in the dust removal groove, and the bottom end of the dust removal plate 7 is fitted to the dust filter plate 11.

[0033] When the utility model is used, the silicon carbide particles with water adhering to the surface after being crushed are introduced into the drying barrel 1 from the feed port, and before the silicon carbide particles are introduced, the driving motor 5 is started and hot air is supplied in advance;
[0034] After the silicon carbide particles are introduced, the feeding structure transports the silicon carbide particles to the discharge port, and the bottom silicon carbide particles are also moved to the upper layer by the material-moving plate 10 in the feeding structure, so that the silicon carbide particles can better exchange heat with the hot air to evaporate the surface moisture, and the silicon carbide particles hit each other during the movement to fall off the attached dust, and the hot air takes away the dust and enters the air outlet into the air outlet barrel 3, and the dust-removed silicon carbide particles fall from the discharge port;
[0035] The hot air entering the air outlet duct barrel 3 will pass through the gap between the sealing plate and the inner wall of the air outlet duct barrel 3 into the chamber above the arc-shaped dust removal plate, and pass through the dust filter plate 11. The dust carried by the hot air remains on the dust filter plate 11. The filtered hot air enters the gap between the arc-shaped dust removal plate and the arc-shaped guide plate 12, and passes through the guide duct 9 again into the air inlet duct barrel 2 to achieve recycling.
