Description

A new bottom-blown slag furnace for easy cleaning in oxidation smelting Technical Field

[0001] This utility model belongs to the field of bottom blowing furnace cleaning technology, specifically a bottom blowing furnace for easy cleaning of oxidative smelting slag. Background Technology

[0002] During the production process of the bottom-blown furnace, due to the bottom-blowing effect of the oxygen lance, high-temperature slag often splashes onto the inner wall of the water jacket at the feed port and adheres to it. If the adhered slag is not cleaned in time, the slag will accumulate and even form lumps. Over time, this will cause material blockage. The blockage at the feed port will prevent the feed rate from meeting the process requirements, becoming a bottleneck affecting production efficiency and impacting the quality of lead smelting.

[0003] Currently, slag removal from the feed inlet is mainly done manually, which consumes a lot of manpower and time, resulting in low production efficiency. If the blockage is severe, the furnace must be removed for further slag removal, affecting normal production. Furthermore, during manual cleaning, since the person is directly in front of the feed inlet, there is a high risk of burns and other safety accidents if slag is sprayed out.

[0004] In view of this, a new bottom-blown slag furnace for oxidation smelting that is easy to clean is proposed. Summary of the Invention

Detailed Implementation

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0021] Referring to Figures 1-5, a bottom-blown furnace for easy cleaning of oxidative smelting slag includes: a bottom-blown furnace 100, a transfer unit 200, and a cleaning unit 300. The bottom-blown furnace 100 has multiple feeding ports spaced apart along its length on its upper surface. The transfer unit 200 is located on one side of the bottom-blown furnace 100 and includes an X-axis transfer module, a Y-axis transfer module, and a Z-axis transfer module. The cleaning unit 300 is mounted on the Z-axis transfer module and is moved along the X, Y, and Z axes by the X-axis, Y-axis, and Z-axis transfer modules. The cleaning unit 300 includes a detachable drive mechanism and a scraper mechanism that can be placed inside the feeding ports. The scraper mechanism includes scraper rods 34 and scrapers spaced apart circumferentially. Multiple cleaning blades 35 on the outer wall of the scraper 34 are automatically cleaned by an automatically rotating cleaning unit 300 to clean the bottom-blown furnace feed port. During the cleaning process, the cleaning blades 35 are rotated by a drive mechanism to remove slag from the feed port. The cleaning unit is also designed with a transfer unit 200 that can move it in different directions. The cleaning unit can be driven by the X-axis transfer module, Y-axis transfer module and Z-axis transfer module to perform cleaning operations on the feed port at different positions. After cleaning, it can also be moved away from the feed port of the bottom-blown furnace 100 to avoid affecting the normal feeding operation. The whole operation is fully automated, which can greatly reduce the manpower required and make the operation safer.

[0022] The transfer unit 200 and the cleaning unit 300 are electrically connected to an externally installed electrical control box (not shown in the figure), and the operation of the transfer unit 200 and the cleaning unit 300 is controlled by the electrical control box.

[0023] Furthermore, there are four cleaning blades 35, and the bottom of the cleaning blades 35 has a downwardly inclined bevel 351. Of course, in other embodiments, there may be three, six, etc. The bevel 351 of the cleaning blades 35 facilitates the insertion of the cleaning blades 35 into the material blocking the feed port.

[0024] Furthermore, the drive mechanism includes a motor 31 and a rotating rod 32. The output end of the motor 31 is connected to the rotating rod 32. The rotating rod 32 has a mounting groove at the bottom center. The top of the scraper 34 has a mounting rod 341 that matches the mounting groove. When cleaning the feeding port, the scraper mechanism is moved into the feeding port by the transfer unit 200. At this time, the motor 31 drives the rotating rod 32 to rotate. During the rotation of the rotating rod 32, the scraper 34 is driven to rotate. At this time, the scraper 34 synchronously drives the cleaning blade 35 to rotate, so that the inner wall of the feeding port can be cleaned.

[0025] The outer wall of the cleaning blade 35 is in contact with the inner wall of the feeding port, which enables the cleaning operation of the feeding port wall.

[0026] Furthermore, at least one limiting key 321 protrudes from the side wall of the mounting groove, and a keyway 342 that matches the limiting key 321 is recessed inward on the outer wall of the mounting rod 341. The outer wall of the mounting rod 341 is also provided with a threaded hole, and the rotating rod 32 is provided with a smooth hole corresponding to the threaded hole. The mounting rod 341 and the rotating rod 32 are locked together by bolts 33. Through the cooperation of the keyway 342 and the limiting key 321, the position of the mounting rod 341 installed in the rotating rod 32 can be limited, and the position of the smooth hole and the threaded hole can also be limited, resulting in higher installation accuracy. When the blade is damaged to the point of needing replacement, it can be replaced simply by removing the bolts 33, without the need for a complete replacement, which can save on replacement costs.

[0027] Furthermore, the X-axis transfer module includes a horizontal support 20 and an X-axis electric guide rail 23 mounted transversely on the horizontal support 20. Columns 22 are symmetrically arranged on both sides of the bottom of the horizontal support 20, and each column 22 has a base 21 with multiple mounting holes at its bottom. The Y-axis transfer module includes a vertical support 24 and a Y-axis electric guide rail 29 mounted on the side of the vertical support 24. The vertical support 24 is mounted on a slide block provided by the X-axis electric guide rail 23. The Z-axis transfer module includes a vertical support 28 and a Z-axis electric guide rail 25 mounted on the outer wall of the vertical support 28. The vertical support 28 is mounted on a second slide block provided by the Y-axis electric guide rail 29. On seat 27, the bottom of the third slide on the Z-axis electric guide rail 25 is equipped with a mounting base 26 connected to the drive mechanism. The mounting base 26 is connected to the motor 31 of the drive mechanism. This design can drive the cleaning unit 300 to move in different directions. When the bottom of the third slide on the Z-axis electric guide rail 25 moves up and down, it can clear blockages in the feeding port. It can also clean feeding ports at different heights. The cleaning unit 300 can be driven to move along the X-axis and Y-axis through the X-axis transfer module and Y-axis transfer module, thereby enabling cleaning of feeding ports at different positions, making it more versatile.

[0028] In other embodiments, the X-axis transfer module, Y-axis transfer module, and Z-axis transfer module may also employ mechanisms such as lead screw drives or rack and pinion drives, which are not limited here.

[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
