Description

Technical Field

[0001] This utility model relates to the field of cleaning the central tube of a reduction tank, and more specifically, to a self-cleaning mechanism for cleaning the slag from the central tube of a cone-shaped reduction tank. Background Technology

[0002] The central tube of the reduction tank is an important component of the reduction tank. In processes such as vertical tank magnesium smelting, the main function of the central tube is to provide an upward channel for magnesium vapor.

[0003] The central tube of the reduction tank is usually made of seamless steel pipe. Multiple holes are opened in the wall of the seamless steel pipe and an external negative pressure module is set so that magnesium vapor can enter the condensation chamber from the central tube. During the process of magnesium vapor rising, magnesium crystal dust or slag is prone to adhering to the inner wall of the central tube and the inner wall of the central tube holes, causing blockage of the central tube. This leads to the need for frequent slag cleaning during the use of the central tube, which reduces the working efficiency. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of this utility model is to provide a self-cleaning reduction tank cone center tube cleaning mechanism that can realize the self-rotation of the center tube, so that the cleaning device can clean the inner wall and holes of the center tube, thereby achieving self-cleaning of the center tube.

[0005] To solve the above problems, the present invention adopts the following technical solution.

[0006] The self-cleaning reduction tank cone center tube slag removal mechanism includes a sealing device, a center tube and a slag removal device. The sealing device includes a cover, a connecting pipe installed in the middle of the cover, a shell installed at the bottom of the cover, a reinforcing rod installed in the middle of the shell, and a sliding groove symmetrically opened at the center of the inner wall of the shell. The central tube includes a tube body, a limiting ring is installed on the outer wall of the upper end of the tube body, the limiting ring has protrusions symmetrically distributed along the center position, the protrusions match the sliding groove, multiple air inlets are opened in the middle of the tube body, the air inlets are multiple holes located on the same horizontal line, and a tapered tube is installed at the lower end of the tube body. The slag-cleaning device includes a support frame with multiple vertical rods mounted on its lower end. A first and second latch are mounted on the middle of each vertical rod, staggered in their arrangement. A scraper ring is fixedly connected to the outer side of the first latch, which is on the same horizontal line. A fixing ring is slidably connected to the outer side of the second latch, which is also on the same horizontal line. Multiple scraper blocks are mounted on the outer end of the fixing ring, and these scraper blocks can move inside the orifices. Through the spontaneous rotation of the central tube, the slag-cleaning device can clean the inner wall and orifices of the central tube, achieving self-cleaning of the central tube.

[0007] Furthermore, the upper end of the central tube slides in the middle of the housing, and the limiting ring is engaged in the middle of the housing, so that the central tube can move up and down, and the central tube is not easy to come out of the middle of the housing.

[0008] Furthermore, the lower end of the reinforcing rod is fixedly connected to the bracket, and the slag removal device is located in the middle of the central tube, so that the slag removal device can be limited, and the slag removal device can perform slag removal work on the inner wall and holes of the central tube.

[0009] Furthermore, the scraper ring is attached to the inner wall of the pipe, and the conical pipe is a hollow cone, so that the scraper ring can scrape off the slag blocks on the inner wall of the pipe through movement, and the slag blocks scraped off by the slag removal device can be discharged through the conical pipe.

[0010] Compared with existing technologies, the advantages of this utility model are: (1) This scheme enables the cleaning device to clean the inner wall and holes of the central tube by the spontaneous rotation of the central tube, thereby achieving self-cleaning of the central tube.

[0011] (2) The self-cleaning of the central tube reduces the need for frequent manual cleaning. The inner wall and holes of the central tube can be self-cleaned by the movement of the central tube, which solves the problems of cleaning the inner wall and clogging the small holes, reduces the frequency of the central tube needing to be stopped for maintenance, and improves the working efficiency of the reduction tank.

[0017] Please see Figure 1-9 The self-cleaning reduction tank cone center tube slag removal mechanism includes a sealing device 1, a center tube 2 and a slag removal device 3. The sealing device 1 includes a cover 101, a connecting tube 102 installed in the middle of the cover 101, a shell 103 installed at the bottom of the cover 101, a reinforcing rod 104 installed in the middle of the shell 103, and a sliding groove 105 symmetrically opened at the center position of the inner wall of the shell 103. The central tube 2 includes a tube body 201. A limiting ring 202 is installed on the outer wall of the upper end of the tube body 201. The limiting ring 202 has protrusions 203 symmetrically distributed along the center position. The protrusions 203 match the sliding groove 105. Multiple air inlets are opened in the middle of the tube body 201. The air inlets are multiple holes 204 located on the same horizontal line. A tapered tube 205 is installed at the lower end of the tube body 201. The slag removal device 3 includes a support 301. Multiple vertical rods 302 are installed at the lower end of the support 301. A first buckle 303 and a second buckle 304 are installed in the middle of the vertical rods 302. The first buckle 303 and the second buckle 304 are staggered in the middle of the vertical rods 302. A slag scraping ring 305 is fixedly connected to the outside of the first buckle 303 located on the same horizontal line. A fixing ring 306 is slidably connected to the outside of the second buckle 304 located on the same horizontal line. Multiple slag scraping blocks 307 are installed at the outer end of the fixing ring 306. The slag scraping blocks 307 can move inside the hole 204.

[0018] Please see Figure 2-4 The upper end of the central tube 2 slides in the middle of the housing 103, and the limiting ring 202 is engaged in the middle of the housing 103, allowing the central tube 2 to move up and down, and preventing the central tube 2 from easily detaching from the middle of the housing 103. The lower end of the reinforcing rod 104 is fixedly connected to the bracket 301, and the slag cleaning device 3 is located in the middle of the central tube 2, allowing the slag cleaning device 3 to be limited, and enabling the slag cleaning device to clean the inner wall of the central tube 2 and the holes 204. The slag scraping ring 305 fits against the inner wall of the tube body 201, and the conical tube 205 is a hollow cone, allowing the slag scraping ring 305 to scrape off the slag from the inner wall of the tube body 201 through movement, and the slag scraped off by the slag cleaning device 3 can be discharged through the conical tube 205.

[0019] During metal reduction smelting, the device is placed inside the reduction tank and installed together with the reduction tank through the cover 101. At this time, the bottom of the conical tube 205 abuts against the bottom of the inside of the reduction tank. The bottom of the inside of the reduction tank causes the central tube 2 and the sealing device 1 to move relative to each other through the conical tube 205. The upper end of the central tube 2 moves towards the side closer to the cover 101. At this time, the protrusion 203 moves inside the slide groove 105. The protrusion 203 drives the central tube 2 to rotate through the slide groove 105. At the same time, the central tube 2 drives the scraper block 307 to rotate along the center of the fixed ring 306 through the hole 204. At this time, the scraper block 307 is located at the bottom of the hole 204. The reduction vessel is placed in a high-temperature furnace, and the upper end of the connecting pipe 102 is connected to the negative pressure module. The reduction vessel starts the metal reduction process. The metal vapor is extracted by the negative pressure module through the hole 204 and the pipe 201. A small amount of metal vapor condenses and adheres when passing through the hole 204 and the pipe 201. After the metal reaction in the reduction vessel is complete, the cover 101 is opened, and the device is removed from the middle of the reduction vessel. At this time, the bottom of the middle part of the reduction vessel no longer restricts the bottom of the conical tube 205. Under the action of gravity, the central tube 2 moves downward and moves away from the cover 101. During the downward movement of the central tube 2, the hole 204 and the scraper block 307 move relative to each other. The scraper block 307 scrapes off the metal slag adhering to the inner wall of the hole 204. At the same time, the scraper ring 305 and the fixing ring 306 move relative to the tube body 201. The scraper ring 305 and the fixing ring 306 scrape off the metal slag adhering to the inner wall of the tube body 201. The attached metal slag is scraped off. Simultaneously, during the movement of the central tube 2, the protrusion 203 moves in the middle of the slide groove 105. The protrusion 203 drives the central tube 2 to rotate via the slide groove 105. During this movement, the central tube 2, through the scraper block 307, drives the fixing ring 306 to rotate around its center position, causing the second latch 304 and the fixing ring 306 to move relative to each other. The second latch 304 scrapes off the metal slag attached to the outer wall of the fixing ring 306, and the central tube 2 returns to its original position. Simultaneously, the scraped metal slag is discharged through the bottom of the conical tube 205, completing the self-cleaning operation of the central tube. The self-rotation of the central tube 2 enables the cleaning device 3 to clean the inner wall and holes 204 of the central tube 2, achieving self-cleaning of the central tube 2.

[0020] The above description is merely a preferred embodiment of this utility model; however, the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the technical scope disclosed in this utility model, based on the technical solution and its improved concept, should be included within the protection scope of this utility model.
