[0002] Flue gas treatment devices filter and intercept solid or gaseous harmful substances in a substance to prevent them from being directly emitted into the atmosphere and affecting the air quality of the outside environment. They are a green and environmentally friendly environmental purification device. Among them, the high-temperature flue gas of silicon carbide is mainly composed of various solid particulate matter and gas.

[0003] However, if the solid particulate matter in the high-temperature flue gas of silicon carbide is discharged into the atmosphere, it will easily cause pollution to the atmosphere. Therefore, it is necessary to filter out the solid particulate matter in the high-temperature flue gas of silicon carbide through a permeable filter plate. The existing permeable filter plates are all flat plates with limited contact area with the flue gas. Furthermore, the solid particulate matter in the high-temperature flue gas of silicon carbide is easily adhered to one side of the permeable filter plate and the inner wall of the flue gas treatment device after being filtered by the permeable filter plate, which can easily affect the normal operation of the high-temperature flue gas treatment device of silicon carbide.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1 and Figure 2 This utility model provides a technical solution: a silicon carbide smelting flue gas treatment device, including a filter tower 1 and a filter frame 3. The filter tower 1 is connected to an upper tower body 101 on its upper side. The filter tower 1 is supported by a support column 102 welded to its bottom. The filter tower 1 is connected to a slag discharge pipe 202 at its bottom. The filter tower 1 is connected to a flue gas discharge pipe 201 at its top. The filter tower 1 is connected to a filter frame 3 inside its interior. The top of the filter frame 3 is covered with a filter membrane 301.

[0025] This silicon carbide smelting flue gas treatment device includes a filter frame 3 and a filter membrane 301 for filtering and intercepting impurities inside the silicon carbide smelting flue gas. The silicon carbide smelting flue gas after removing impurities is discharged through the exhaust pipe 201 on the upper side of the upper tower body 101, while the impurities accumulated inside the filter tower 1 are discharged through the slag discharge pipe 202.

[0026] exist Figure 2 and Figure 3 In the filter tower 1, an internal connecting pipe 103 is welded inside, and the internal connecting pipe 103 is horizontally arranged inside the filter tower 1. An inlet pipe 2 is inserted inside the internal connecting pipe 103, and the lower side of the inlet pipe 2 is connected to the internal connecting pipe 103 through the pipe. It is used to introduce the silicon carbide smelting flue gas into the filter tower 1. The inlet of the inlet pipe 2 is vertically downward.

[0027] This silicon carbide smelting flue gas treatment device has a horizontally welded internal connecting pipe 103 inside the filter tower 1, which provides suitable space for the reasonable connection of some components. At the same time, the vertically downward-facing inlet pipe 2 can effectively prevent residue inside the filter frame 3 from falling into the inlet pipe 2 and accumulating and clogging it.

[0028] exist Figures 2-5 In the middle: The filter frame 3 has an auxiliary filter ring plate 302 welded inside, which is used to assist the filter frame 3 and the filter membrane 301 in filtering the silicon carbide smelting flue gas. The filter frame 3 and the filter membrane 301 are both semi-circular.

[0029] This silicon carbide smelting flue gas treatment device features a semi-circular arrangement of the filter frame 3 and filter membrane 301, which increases the contact area with the silicon carbide smelting flue gas. This facilitates better and faster contact filtration of the flue gas. Furthermore, the auxiliary filter ring plate 302 welded inside the filter frame 3 further enhances the contact with the flue gas, pre-filtering and removing some impurities. This assists the filter frame 3 and filter membrane 301 in filtering the flue gas, resulting in better performance.

[0030] exist Figure 3 and Figure 4 In the middle: The drive motor 4 is installed inside the inner connecting pipe 103 by locking bolts. The output end of the drive motor 4 is connected to the drive gear 401 through a coupling. The outer side of the drive gear 401 meshes with the transmission gear 402. The middle part of the transmission gear 402 is connected to the rotating rod 403.

[0031] This silicon carbide smelting flue gas treatment device starts the drive motor 4, and the output end of the drive motor 4 drives the drive gear 401 to rotate through the coupling and mesh with the transmission gear 402 on the outside of the rotating rod 403, thereby driving the transmission gear 402 and the rotating rod 403 in the middle of the transmission gear 402 to rotate.

[0032] exist Figures 2-5 In the middle section: the rotating rod 403 is rotatably connected to the inner connecting pipe 103 through a sealed bearing, and the rotating rod 403 is installed through the middle of the inner connecting pipe 103. Scrapers 404 are welded at equal intervals on the top of the rotating rod 403. The surface of the scraper 404 is in contact with the inner wall of the filter frame 3 and the outer wall of the auxiliary filter ring plate 302, and is used to scrape the inner wall of the filter frame 3 and the outer wall of the auxiliary filter ring plate 302.

[0033] In this silicon carbide smelting flue gas treatment device, when the rotating rod 403 rotates, the rotating rod 403 will drive the scraper 404 welded to the top to rotate, scraping the inner wall of the filter frame 3 and the outer wall of the auxiliary filter ring plate 302 that are attached to its surface, and scraping the filtered residue to the bottom of the filter tower 1.

[0034] exist Figures 2-4 In the middle: a scraper rod 406 is welded to the outside of the rotating rod 403 to scrape the residue at the top of the inner connecting pipe 103. Support rods 407 are welded at equal intervals at the bottom of the rotating rod 403. Scraper rods 408 are welded to the outside of multiple support rods 407. The outer wall of the scraper rods 408 is in contact with the inner wall of the filter tower 1.

[0035] In this silicon carbide smelting flue gas treatment device, when the rotating rod 403 rotates, it scrapes the top of the inner connecting pipe 103 through the scraper 406 to prevent the residue from accumulating and growing on the top of the inner connecting pipe 103. At the same time, the rotating rod 403 drives the scraper 408 to rotate through the support rod 407 to prevent the residue from adhering to the inner wall at the bottom of the filter tower 1 and being difficult to discharge later.

[0036] exist Figures 2-4 In the middle: the rotating rod 403 is welded with guide fan blades 405 at equal intervals on the outside, which are used to guide the silicon carbide smelting flue gas introduced into the filter tower 1 to the filter frame 3.

[0037] This silicon carbide smelting flue gas treatment device, by rotating the rotating rod 403 to drive the guide fan blades 405 to rotate, can smoothly guide the silicon carbide smelting flue gas to the filter frame 3 for filtration, preventing the silicon carbide smelting flue gas from escaping around inside the filter tower 1, and can further enhance the filtration efficiency of the filter tower 1 for silicon carbide smelting flue gas.

[0038] Working principle: When using this silicon carbide smelting flue gas treatment device, the silicon carbide smelting flue gas is introduced into the filter tower 1 through the flue gas inlet pipe 2. The drive motor 4 is started and drives the drive gear 401 and the transmission gear 402 to mesh through the coupling, thereby driving the rotating rod 403 to rotate, which in turn drives the guide fan blade 405 to rotate, guiding the silicon carbide smelting flue gas to the filter frame 3, the auxiliary filter ring plate 302 and the filter membrane 301 for filtration. The silicon carbide smelting flue gas after removing impurities will be discharged through the flue gas exhaust pipe 201 on the upper side of the upper tower body 101, while the impurities accumulated inside the filter tower 1 will be discharged through the slag discharge pipe 202. The contents not described in detail in this description are existing technologies known to those skilled in the art.

[0039] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
