Description

Technical Field

[0001] The utility model relates to the technical field of cleaning dust accumulation in silicon furnaces, and more specifically, to a cleaning device for cleaning dust accumulation in industrial silicon furnaces used for exhaust gas emission. Background Art

[0002] In industrial production, it is often necessary to produce metallic silicon through silicon furnaces. When processing metallic silicon, since the silicon furnace needs to frequently emit exhaust gas during use, this will cause more silicon ash to be produced inside the silicon furnace exhaust pipe. In order to ensure the stability of exhaust gas emissions, it is very important to clean the silicon ash.

[0003] As retrieved, the relevant patent: CN220206407U discloses an industrial silicon furnace dust cleaning device. This prior art uses an annular cleaning plate to scrape the dust on the inner wall of the exhaust pipe, and uses a second cleaning nozzle to flush and clean the inner wall of the exhaust pipe, which is conducive to thoroughly cleaning the inner wall of the exhaust pipe.

[0004] However, the inventor discovered that the prior art has the following problems when in use: when the annular cleaning plate in the prior art scrapes off the dust on the inner wall of the exhaust pipe, the scraped dust will fall directly into the industrial silicon furnace through the exhaust pipe. However, in actual use, the industrial silicon furnace will emit waste gas through the exhaust pipe for a long time, which will cause a large amount of dust to form on the inner wall of the exhaust pipe, while the inner wall of the industrial silicon furnace has less dust. Therefore, most of the time, only the inner wall of the exhaust pipe is cleaned. If the dust falls into the industrial furnace during the cleaning of the inner wall of the exhaust pipe, the staff will need to clean the industrial silicon furnace, which increases the operating steps of the staff. In response to the above problems, the inventor has designed an industrial silicon furnace dust cleaning device for waste gas emissions. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of the utility model is to provide an industrial silicon furnace ash cleaning device for waste gas discharge that avoids as much as possible the scraped ash falling into the industrial silicon furnace and the need to clean the industrial silicon furnace, reduces the operating steps when cleaning the inner wall of the industrial silicon furnace exhaust pipe, and can quickly clean the inner wall of the industrial silicon furnace exhaust pipe.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0023] See also Figure 1-4 , the utility model provides the following technical solutions:

[0024] Specifically, it refers to an industrial silicon furnace dust cleaning device for waste gas emissions, including an industrial silicon furnace waste pipe 1 and a cleaning component 2 arranged on the industrial silicon furnace waste pipe 1, the cleaning component 2 includes a top plate 201, the top plate 201 is arranged directly above the industrial silicon furnace waste pipe 1, and the lower surface of the top plate 201 is fixedly connected to two supporting legs 202, the lower sides of the two supporting legs 202 are respectively arranged on the outer surfaces of the industrial silicon furnace waste pipe 1 on opposite sides, the supporting legs 202 and the outer surface of the industrial silicon furnace waste pipe 1 are fixed by bolts, so the two supporting legs 202 form a supporting effect on the top plate 201.

[0025] Specifically, a movable slide plate 203 is slidably sleeved on the top plate 201, and the lower side of the movable slide plate 203 extends into the industrial silicon furnace exhaust pipe 1. A circular scraper plate 204 is provided on the lower side of the movable slide plate 203, and the outer surface of the circular scraper plate 204 is in contact with the inner wall of the industrial silicon furnace exhaust pipe 1. A motor 205 is fixedly connected to the upper surface of the top plate 201, and one end of the output shaft of the motor 205 is fixedly connected to the first gear 206. A tooth groove 207 is provided on the side of the movable slide plate 203 close to the first gear 206, and one side of the first gear 206 is meshed with the tooth groove 207. Therefore, when the motor 205 is started, the output shaft of the motor 205 can drive the first gear 206 to rotate, so that the movable slide plate 203 is on the first gear 2 06 moves upward or downward under the meshing transmission with the tooth groove 207. When the inner wall of the industrial silicon furnace exhaust pipe 1 needs to be cleaned, it is only necessary to control the movable slide plate 203 to move upward, so that the outer surface of the circular scraper 204 slides on the industrial silicon furnace exhaust pipe 1, so that the dust attached to the inner wall of the industrial silicon furnace exhaust pipe 1 can be scraped off. Since the outer surface of the circular scraper 204 fits the inner wall of the industrial silicon furnace exhaust pipe 1, the scraped dust will fall on the circular scraper 204. In this way, it is avoided as much as possible that the scraped dust falls into the industrial silicon furnace and needs to be cleaned inside the industrial silicon furnace, which reduces the operating steps when cleaning the inner wall of the industrial silicon furnace exhaust pipe 1, and the inner wall of the industrial silicon furnace exhaust pipe 1 can be quickly cleaned.

[0026] Specifically, the upper surface of the circular scraper 204 is fixedly connected with a U-shaped connecting seat 208, the lower surface of the movable slide plate 203 is fixedly connected with a rotating plate 209, and a rotating shaft 210 is fixedly connected between the U-shaped connecting seats 208. The rotating plate 209 is rotatably sleeved on the outer surface of the rotating shaft 210, so that the circular scraper 204 rotates into a vertical shape with the U-shaped connecting seat 208 as the rotating point. Therefore, when the circular scraper 204 is extended into the industrial silicon furnace exhaust pipe 1, the contact area between the circular scraper 204 and the inner wall of the industrial silicon furnace exhaust pipe 1 is reduced, and most of the accumulated dust on the inner wall of the industrial silicon furnace exhaust pipe 1 is avoided from being scraped off into the industrial silicon furnace when the circular scraper 204 moves downward. When the circular scraper 204 is extended into the industrial silicon furnace, the circular scraper 204 is rotated in the opposite direction, and the circular scraper 204 is controlled to move upward, so that the inner wall of the industrial silicon furnace exhaust pipe 1 can be cleaned.

[0027] Specifically, the U-shaped connecting seat 208 is arranged on one side close to the center of the circular scraper 204, so that when the circular scraper 204 is rotated into a vertical shape, it can be in the same vertical direction as the center of the industrial silicon furnace exhaust pipe 1, thereby avoiding the situation where the circular scraper 204 rotated into a vertical shape cannot be extended into the industrial silicon furnace exhaust pipe 1.

[0028] Specifically, a driving cavity 211 is opened in the rotating plate 209, and a rotating shaft 210 is arranged in the driving cavity 211. A second gear 212 is fixedly sleeved on the outer surface of the rotating shaft 210 located in the driving cavity 211. An adjusting plate 213 is provided on the side of the second gear 212. A plurality of teeth 214 are fixedly connected to the surface of the adjusting plate 213 on one side close to the second gear 212. Therefore, the adjusting plate 213 is meshed and connected with the second gear 212 through the teeth 214. When the adjusting plate 213 moves upward, the adjusting plate 213 can drive the second gear 214 to rotate ninety degrees in a clockwise direction, thereby achieving the purpose of controlling the rotation of the circular scraper 204.

[0029] Specifically, a mounting plate 215 is slidingly sleeved on the upper outer surface of the adjusting plate 213, and the mounting plate 215 is fixedly connected to the inner wall of the driving cavity 211. A rotating shaft 216 is provided on the upper side of the movable sliding plate 203, and the lower end of the rotating shaft 216 rotates and passes through the driving cavity 211. A screw 217 is fixedly connected to the lower end of the rotating shaft 216. A threaded groove 218 threadedly sleeved on the outer surface of the screw 217 is provided on the upper surface of the adjusting plate 213. In this way, by twisting the rotating shaft 216, the adjusting plate 213 can be displaced under the threaded transmission of the screw 217 and the threaded groove 218. At the same time, the threaded transmission method is adopted to make the adjusting plate 213 have a self-locking effect, which further ensures the firmness of the circular scraper 204 after adjustment.

[0030] The working principle of the industrial silicon furnace dust cleaning device for exhaust gas emission provided by the utility model is as follows: the motor 205 is started, and the output shaft of the motor 205 can drive the first gear 206 to rotate, so that the movable slide plate 203 moves upward or downward under the meshing transmission of the first gear 206 and the tooth groove 207;

[0031] When it is necessary to clean the inner wall of the industrial silicon furnace exhaust pipe 1, it is only necessary to control the movable slide plate 203 to move upward, so that the outer surface of the circular scraper 204 slides on the industrial silicon furnace exhaust pipe 1, so that the accumulated dust attached to the inner wall of the industrial silicon furnace exhaust pipe 1 can be scraped off. Since the outer surface of the circular scraper 204 fits with the inner wall of the industrial silicon furnace exhaust pipe 1, the scraped dust will fall on the circular scraper 204.
