Description

Technical Field

[0001] The invention relates to the technical field of slag removal in a bottom blowing furnace, in particular to slag removal equipment at a feeding port of a bottom blowing furnace. Background Art

[0002] SKS lead smelting method is an oxygen bottom blowing direct lead smelting method independently developed by my country, which belongs to the category of molten pool smelting. The materials are put into the furnace and complete the processes of heating, melting, oxidation, slag making, and matte making at the same time. The charge is added from the top of the smelting furnace, and oxygen-enriched air is sent into the bottom to stir the molten pool. The materials put into the furnace complete the smelting process in the molten pool, and the crude lead, high-lead slag and flue gas produced are discharged from the lead discharge port, slag discharge port, and smoke exhaust port respectively.

[0003] The bottom-blown furnace will cause slag to form at the feed port due to slag jumping inside the furnace, which will affect the flow of goods into the furnace body. Currently, the slag at the feed port is cleaned manually at irregular intervals. This project is mainly to realize the intelligent and automatic slag removal of the slag at the top feed port of the bottom-blown furnace.

[0004] In the prior art, the slag removal method for the slag at the top feeding port of the bottom blowing furnace requires the operator to manually use a pick to squeeze and contact the slag in the feeding port to remove the slag. However, there are some defects in the process. When removing the slag at the feeding port, it is difficult to adjust the length of the pick, which makes it difficult for the operator to remove the local slag in the feeding port. The existing pick has a square head and a flat head. When clamped by a robot, it cannot get a fulcrum on the edge like manual operation, so that the pick can work efficiently. It often cannot work continuously because of the thick and hard slag at the furnace mouth. For this reason, we propose a slag removal equipment for the feeding port of a bottom blowing furnace.

By setting a pushing component 31, when it is necessary to remove the slag inside the bottom blowing furnace inlet, it is necessary to adjust the length of the sleeve 3110 to facilitate the removal of the slag inside the inlet. At this time, the operator connects the first connecting flange 1 and the second connecting flange 2 to the robotic arm, and then turns on the forward and reverse motor 317 to cause the screw rod 318 to rotate. During the rotation of the screw rod 318, the sleeve block 319 is limited by the vertical plate 3123, which will cause the sleeve block 319 to move upward along the outer wall of the screw rod 318. During the upward movement of the sleeve block 319, the sleeve 3110 will be moved upward with it, thereby adjusting the telescopic length of the sleeve 3110. After the telescopic length of the sleeve 3110 is adjusted, the operator turns off the forward and reverse motor 317 to fix the position of the sleeve 3110 after the telescopic length is adjusted, so that the robotic arm can scrape the slag deep inside the inlet.

[0020] A preferred embodiment of the slag removal device for a bottom blowing furnace provided by the present invention is as follows: Figures 1 to 9As shown: a connecting assembly 32 is also provided at the top of the sleeve 3110, and the connecting assembly 32 includes a connecting groove 321 opened at the top of the sleeve 3110, and a positioning column 322 is slidably connected to the inner wall of the connecting groove 321, and a rectangular block 323 is fixedly connected to the top of the positioning column 322, and a pick bit 324 is fixedly connected to the top of the rectangular block 323, and a side plate 325 is fixedly connected to the top of the sleeve 3110, and a limiting column 326 is slidably connected to the inner wall of the side of the rectangular block 323.

By setting the connecting assembly Part 32, before adjusting the telescopic length of the sleeve 3110, the operator needs to connect the pick drill bit 324 with the top of the sleeve 3110, so as to facilitate the scraping of the slag through the pick drill bit 324. At this time, the operator pulls the pull plate 327 to prompt the pull plate 327 to pull the limit column 326 to move, prompting the spring 328 to extend. Then, the operator installs the positioning column 322 to the inside of the connecting groove 321 to make the bottom of the rectangular block 323 fit with the top of the sleeve 3110. Then, by releasing the pull plate 327, the limit column 326 will be reset under the reaction of the spring 328, prompting the limit column 326 to be inserted into the side of the rectangular block 323, thereby fixing the position of the rectangular block 323 and the pick drill bit 324.

[0021] The pushing assembly 31 also includes a supporting plate 329 fixedly connected to the outer wall of the pick bit 324, and a scraper 3210 is fixedly connected to the top of the supporting plate 329. The side wall of the scraper 3210 is arranged in a serrated shape. By arranging the supporting plate 329 and the scraper 3210 with a serrated shape on the outer wall of the pick bit 324, it is convenient for the robotic arm to scrape the slag on the inner wall of the feed port through the scraper 3210 on the side wall of the pick bit 324.

[0022] Furthermore, there are four reinforcing ribs 311, which are equal in size and are distributed in a circular array along the central axis of the second connecting flange 2 at the top of the second connecting flange 2. By setting up four reinforcing ribs 311, it is convenient to provide stable support for the second connecting flange 2.

[0023] Furthermore, there are two vertical plates 3123 , which are symmetrically distributed on both sides of the sleeve block 319 along the center plane. By providing two vertical plates 3123 , it is convenient to limit the sleeve block 319 and enable the sleeve block 319 to move on the outer wall of the screw rod 318 .

[0024] Furthermore, there are five cleaning rollers 3122 , which are of equal size and are distributed in a circular array along the inner wall of the transmission gear 3115 . The five cleaning rollers 3122 are arranged to facilitate cleaning of the slag attached to the surface of the sleeve 3110 .

[0025] In addition, the outer wall of one end of the limiting column 326 is matched with the inner wall of the side surface of the rectangular block 323 , and the other end of the limiting column 326 is fixedly connected to the side wall of the pulling plate 327 .

[0026] Working principle: Before adjusting the telescopic length of the sleeve 3110, the operator needs to connect the pick bit 324 with the top of the sleeve 3110, so as to facilitate the scraping of the slag through the pick bit 324. At this time, the operator pulls the pull plate 327 to cause the pull plate 327 to pull the limit column 326 to move, causing the spring 328 to extend. Then, the operator installs the positioning column 322 into the inside of the connecting groove 321 to make the bottom of the rectangular block 323 and the sleeve 3110 The top of the rectangular block 323 is fitted, and then the pull plate 327 is released. Under the reaction of the spring 328, the limiting column 326 is reset, so that the limiting column 326 is inserted into the side of the rectangular block 323, thereby fixing the position of the rectangular block 323 and the pick drill bit 324. By arranging a bearing plate 329 and a serrated scraper 3210 on the outer wall of the pick drill bit 324, the robot arm can scrape the slag on the inner wall of the feed port through the scraper 3210 on the side wall of the pick drill bit 324. When it is necessary to remove the slag inside the bottom blowing furnace inlet, it is necessary to adjust the length of the sleeve 3110 to facilitate the removal of the slag inside the inlet. At this time, the operator connects the first connecting flange 1 and the second connecting flange 2 to the robotic arm, and then turns on the forward and reverse motor 317 to cause the screw rod 318 to rotate. During the rotation of the screw rod 318, the sleeve block 319 is limited by the vertical plate 3123, which causes the sleeve block 319 to move upward along the outer wall of the screw rod 318. During the upward movement of the sleeve block 319, the sleeve 3110 is moved upward with it, thereby adjusting the telescopic length of the sleeve 3110. After the telescopic length of the sleeve 3110 is adjusted, the operator turns off the forward and reverse motor 317 to fix the position of the sleeve 3110 after the telescopic length is adjusted, so that the robotic arm can scrape the slag deep inside the inlet. After the slag inside the feed port is removed, during the downward contraction of the sleeve 3110, the operator turns on the drive motor 3112 to cause the output shaft 3113 to rotate. During the rotation of the output shaft 3113, the driving gear 3114 is rotated with it, and after the driving gear 3114 rotates, it engages with the transmission gear 3115. The transmission gear 3115 is limited by the first limit block 3116 and the second limit block 3119, which causes the transmission gear 3115 to rotate, and after the transmission gear 3115 rotates, it causes the U-shaped block 3120 to rotate. When the sleeve 3110 moves downward, the U-shaped block 3120 causes the cleaning roller 3122 inside it to rotate, thereby facilitating the cleaning of the slag attached to the surface of the sleeve 3110 during the slag removal process.
