[0028] The following combines Figures 1 to 3 the illustrated embodiment to describe the technical solution of the present utility model:
[0029] The present utility model provides a silicon carbide smelting furnace with a silicon carbide tailing recycling and reuse structure, including: a smelting furnace main body 1; a feed inlet 2 opened above one end of the smelting furnace main body 1; slide rails 3 arranged on two opposite sides of the inner wall of the smelting furnace main body 1, and the slide rails 3 are arranged on one side of the side wall of the smelting furnace main body 1 close to the bottom wall; a sliding plate 4 slidably arranged on the slide rails 3, and one end of the sliding plate 4 is fixedly provided with a pull rod 401.
[0030] Figures 1 to 3 An example of a silicon carbide smelting furnace with a silicon carbide tailing recycling and reuse structure of a specific structure is provided. It can be understood that the present utility model provides a silicon carbide smelting furnace with a silicon carbide tailing recycling and reuse structure. By collecting the tailings of silicon carbide and laying them flat at the bottom of the silicon carbide smelting furnace, the output of the silicon carbide smelting furnace can be effectively increased, and at the same time, the power consumption of the silicon carbide smelting furnace can be reduced, increasing the enterprise profit while reducing the production cost, and greatly reducing the environmental pollution.
[0031] The silicon carbide smelting furnace main body 1 has a horizontally placed cylindrical barrel shape with a refractory brick inner liner 101 arranged inside, and its shape is a square heat preservation device. The left and right sides of the silicon carbide smelting furnace main body 1 are open. The left opening is the port for putting silicon carbide raw materials, and the right opening is the outlet after silicon carbide smelting. The silicon carbide raw materials enter the interior of the silicon carbide smelting furnace through the left opening of the silicon carbide smelting furnace main body 1 for smelting. The silicon carbide smelting furnace main body 1 is fixedly arranged on the ground through four pillars, which is convenient for feeding and smelting. At the same time, both ends of the bottom of the refractory brick inner liner 101 arranged inside the silicon carbide smelting furnace have a certain height, that is, the bottom is a groove with a certain depth, which is convenient for laying silicon carbide tailings and avoiding the silicon carbide tailings from sliding outside the smelting furnace.
[0032] The feed inlet 2 is opened above one end of the smelting furnace body 1. The feed inlet 2 is arranged in a hollow cylindrical structure, which is convenient for the workers to add the silicon carbide tailings into the interior of the smelting furnace body 1. The feed inlet 2 is arranged at the inlet end on the left side of the smelting furnace body 1. Before adding the silicon carbide raw materials, it is necessary to first add the silicon carbide tailings into the smelting furnace body 1 through the feed inlet 2.
[0033] There are two slide rails 3 in total, which are respectively arranged on two opposite sides of the inner wall of the square structure in the smelting furnace body 1. The slide rails 3 are arranged in a rectangular structure. The sliding grooves are opened on the opposite sides of the two slide rails 3. The material of the slide rails 3 is the same as that of the inner wall of the refractory brick inner tank 101 of the smelting furnace body 1. The slide rails 3 are arranged on one side of the side wall of the smelting furnace body 1 close to the bottom wall. The slide rails 3 have a certain distance from the bottom wall. The height of the slide rails 3 is matched with the preset paving thickness of the silicon carbide tailings. The length of the slide rails 3 is matched with the length of the inner wall of the smelting furnace body 1.
[0034] The sliding plate 4 is slidably and detachably arranged on the slide rails 3. The two ends of the sliding plate 4 are matched with the shape of the slide rails 3. Since the sliding grooves of the slide rails 3 in the present utility model are in the shape of a horizontally placed T-shaped groove with two narrow openings facing each other, that is, the smaller diameter ends of the two grooves are opened on the opposite sides of the two slide rails 3. The two ends of the sliding plate 4 are rotatable pulleys, and the diameter of the pulleys is matched with the larger diameter part of the sliding groove, which is convenient for the sliding plate 4 to slide freely in the sliding groove. A pull rod 401 is fixedly arranged at one end of the sliding plate 4 away from the left side of the smelting furnace body 1. When adding the silicon carbide tailings, open the door on the right side of the smelting furnace body 1 and close the door on the left side of the smelting furnace body 1 to facilitate the workers to pour the silicon carbide tailings. The pull rod 401 is a cylindrical electric telescopic structure. At the same time, an anti-slip sleeve is arranged at the tail end of the pull rod 401, and the size is selected to be convenient for the workers to hold. When it is necessary to level the silicon carbide tailings, the workers can start the electric telescopic pull rod 401 to easily and evenly add the silicon carbide tailings.
[0035] The silicon carbide smelting furnace with a silicon carbide tailings recycling and reuse structure provided by the present utility model can add the silicon carbide tailings into the silicon carbide smelting furnace, and then through the cooperation of the sliding plate 4 and the slide rails 3, evenly spread the silicon carbide tailings on the bottom wall of the silicon carbide smelting furnace. The average output per furnace of the silicon carbide smelting furnace with the laid silicon carbide tailings has increased by 200 tons. While the enterprise profit has increased greatly, the power consumption per furnace has also decreased by 630 Kwh, having good economic and environmental benefits.
[0036] According to the silicon carbide smelting furnace with a silicon carbide tailings recycling and reuse structure provided by the present utility model: The feed inlet 2 includes a feed pipe 201 and a top cover 202. One end of the feed pipe 201 is communicated with the interior of the smelting furnace body 1, and the other end of the feed pipe 201 is detachably connected to the top cover 202 by bolts. A refractory brick seal is fixedly arranged on the surface of the top cover 202 close to the feed pipe 201.
[0037] In the silicon carbide smelting furnace with a silicon carbide tailing recycling and reuse structure provided by the present utility model, the feed inlet 2 includes two parts, a feed pipe 201 and a top cover 202. The shape of the feed pipe 201 is a hollow cylinder. The feed pipe 201 is arranged at the left end of the smelting furnace body 1. The diameter of the feed pipe 201 is larger than the diameter of the silicon carbide tailings, which is convenient for the staff to pass the silicon carbide tailings into the smelting furnace through the feed pipe 201. However, there is also a certain distance between the feed pipe 201 and the left end opening of the smelting furnace body 1. When a certain accumulation of silicon carbide tailings is added, it can prevent the silicon carbide tailings from falling outside the smelting furnace body 1.
[0038] The shape of the top cover 202 matches the shape of the feed pipe 201. A refractory brick seal is fixedly arranged on the side of the top cover 202 close to the feed pipe 201. The diameter of the refractory brick seal matches the diameter of the feed pipe 201. When it is necessary to add silicon carbide tailings, the top cover 202 is removed, and the silicon carbide tailings are passed into the interior of the smelting furnace body 1 through the feed pipe 201. After the silicon carbide tailings are spread evenly, one end of the refractory brick seal is aligned with the position of the feed port 2 of the feed pipe 201, and then the top cover 202 is fixed to the top of the feed pipe 201 by bolts, which is convenient for subsequent smelting of the silicon carbide raw materials. Setting the refractory brick seal on the top cover 202 can also ensure the temperature inside the smelting furnace. The length of the refractory brick seal matches the length of the feed pipe 201, and it can ensure to the greatest extent that the temperature inside the smelting furnace does not escape. After the top cover 202 is fixed above the feed pipe 201, the height of the bottom surface of the refractory brick seal is flush with the height of the inner wall at the top of the refractory brick inner liner 101, ensuring a good heat preservation and smelting effect in the silicon carbide smelting furnace.
[0039] In the silicon carbide smelting furnace with a silicon carbide tailing recycling and reuse structure provided by the present utility model: A handle 203 is fixedly arranged at the end of the top cover 202 far from the feed pipe 201, and the surface of the handle 203 is covered with a rubber anti-slip sleeve.
[0040] In the present utility model, a handle 203 is fixedly arranged at the end of the top cover 202 far from the feed pipe 201, which is convenient for the staff to disassemble and install the top cover 202. The surface of the handle 203 is covered with a rubber anti-slip sleeve. Setting the rubber anti-slip sleeve not only facilitates the staff to hold, but also can play a certain degree of heat insulation role, improving the safety and practicality of the staff's work.
[0041] In the silicon carbide smelting furnace with a silicon carbide tailing recycling and reuse structure provided by the present utility model: The length of the slide rail 3 matches the length of the inner wall of the smelting furnace body 1, and there is a certain distance between the sliding plate 4 and the bottom wall of the smelting furnace body 1.
[0042] In the present utility model, the length of the sliding rail 3 matches the length of the inner wall of the smelting furnace body 1. There is a certain distance between the sliding plate 4 and the bottom wall of the smelting furnace body 1, which facilitates the sliding plate 4 to spread the added silicon carbide tailings evenly on the bottom wall of the smelting furnace body 1. The function of the sliding plate 4 is to level the silicon carbide tailings. Therefore, there is a certain distance between the sliding plate 4 and the smelting furnace body 1, so as to ensure that the thickness of the silicon carbide tailings after leveling can meet the requirements.
[0043] According to the silicon carbide smelting furnace with a silicon carbide tailings recycling and reuse structure provided by the present utility model: a rake-shaped notch is provided at one end of the sliding plate 4 close to the bottom wall of the smelting furnace body 1, which facilitates the sliding plate 4 to level the tailings.
[0044] In the present utility model, a rake-shaped notch is provided at one end of the sliding plate 4 close to the bottom wall of the smelting furnace body 1. The shape of the notch is specifically selected as a rectangle, and the rectangles are distributed in an array. This facilitates the sliding plate 4 to evenly spread and level the tailings. After the silicon carbide tailings start to be added from the feed inlet 2, the pulleys at both ends of the sliding plate 4 are placed in the corresponding grooves of the sliding rail 3. Two workers add the silicon carbide tailings while spreading the tailings evenly on the upper part of the inner bottom wall of the smelting furnace body 1 through the sliding plate 4.
[0045] The working principle of the present utility model: Open the top cover 202 of the feed inlet 2 and the door on the right side of the smelting furnace body 1, install the sliding plate 4 on the sliding rail 3, then add silicon carbide tailings into the smelting furnace body 1 while spreading the silicon carbide tailings evenly on the inner bottom wall of the smelting furnace body 1 through the sliding plate 4. After the silicon carbide tailings are evenly spread, close the door on the right side of the smelting furnace body 1 and the top cover 202 of the feed inlet 2. Then open the door on the left side of the smelting furnace body 1 to put the silicon carbide raw material to be smelted, and then close the door on the left side of the smelting furnace body 1 to start smelting. The obtained silicon carbide product increases, and at the same time, the energy consumption decreases. While improving the economic benefits, it also improves the environmental benefits and enhances the development potential of the enterprise.
[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model, rather than to limit them; although the present utility model has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the various embodiments of the present utility model.
