Description

Technical Field

[0001] The utility model relates to the technical field of fuming furnaces, in particular to a coal conveying pipeline of a fuming furnace which is convenient to clean. Background Technique

[0002] When smelting tin metal in an electric furnace, a large amount of rich slag is produced, containing about 10% tin. It needs to be recovered by slag smelting in a fuming furnace. The electric furnace rich slag is directly sent to the fuming furnace for sulfidation volatilization treatment. The fuming furnace treats the rich slag, and the furnace temperature is about 1200 °C. The tin in the slag is sulfided into volatile stannous sulfide and volatilized, oxidized into oxides, and then recovered in the form of soot. The collected soot is returned to the electric furnace for treatment, and the fuming furnace slag is sold externally. The flue gas is sent to the tail gas treatment system for treatment after recovering waste heat through a waste heat boiler, cooling through a surface cooler, and bag dust collection and reaching the standard for discharge.

[0003] Chinese patent document CN219870507U discloses a fuming furnace for efficiently recovering tin in waste metals and tin-containing materials. It has a furnace barrel and a flue. The furnace barrel has a feeding port, a slag cleaning port, a water jacket device and an air inlet. The flue is a horizontal pipe or a pipe with an elevation angle within 30 degrees. There is an aggregate hopper on the lower wall of the pipe. There is a discharge gate at the lower part of the aggregate hopper. The aggregate hopper can be one or multiple, and the aggregate hoppers are evenly distributed in the settling area. The discharge port of the aggregate hopper is located above the return material port of the furnace barrel, so that the materials in the aggregate hopper can flow back to the furnace chamber for combustion again by gravity. The utility model completely changes the problem of siltation and blockage of the traditional fuming furnace flue. While keeping large-grained materials regularly returning to the furnace chamber for repeated combustion and volatilization, the flue is kept unobstructed. The processing capacity of the fuming furnace is increased by 30 - 50%, the volatilization rate of non-ferrous metals such as tin is 95% - 98%, the production cost is reduced by more than 10%, and it also avoids the work injury accidents and the risk of suffering from occupational diseases brought by workers entering the flue for dredging. However, the coal conveying pipeline of this device is not equipped with relevant cleaning mechanisms. Some pulverized coal will deposit in the pipeline and cannot enter the fuming furnace without external assistance, resulting in a large amount of loss. Moreover, the pulverized coal accumulates in the pipeline for a long time, is easy to melt and adhere to the inner wall of the conveying pipeline, is blocked very severely, and is also very laborious to clean.

[0004] Therefore, in order to solve such problems, we propose a coal conveying pipeline of a fuming furnace which is convenient to clean. Content of the Utility Model

The inside of the storage cylinder 3 is connected to the inside of the coal conveying pipeline 2. An installation block 4 is fixedly installed on one side of the storage cylinder 3 away from the coal conveying pipeline 2. A coal feeding port 5 is arranged at the top of one end of the coal conveying pipeline 2 close to the storage cylinder 3. Pulverized coal is conveyed into the coal conveying pipeline 2 through the coal feeding port 5. A cleaning component 6 is arranged inside the coal conveying pipeline 2 to clean the pulverized coal accumulated inside the coal conveying pipeline 2 and avoid blocking the pipeline;

[0025] The cleaning assembly 6 includes a first motor 61 fixedly installed on the outer side of the mounting block 4. The output end of the first motor 61 is connected to a rotating rod 62 which is telescopic. One end of the rotating rod 62 away from the first motor 61 penetrates and extends into the interior of the storage cylinder 3 and is connected to an adjusting member 63. A moving ring 64 is movably sleeved outside the adjusting member 63. An active rod 65 is rotatably connected to the outside of the moving ring 64. One end of the active rod 65 away from the moving ring 64 is rotatably provided with a fixed bracket 66. A cleaning brush 67 is provided on one side of the fixed bracket 66 away from the active rod 65. One end of the fixed bracket 66 away from the active rod 65 is rotatably provided with a driving rod 68. A fixed sleeve 69 is movably provided at the lower end of the driving rod 68. Positioning blocks 641 are installed on the outer walls of the moving ring 64 and the fixed sleeve 69.

The driving rod 68 is rotatably arranged on both sides of the positioning block 641 on the fixed sleeve 69 through a screw 642. The fixed sleeve 69 is fixedly arranged on the outside of the rotating rod 62. By controlling the movement of the moving ring 64 through the adjusting member 63, the active rod 65 pushes the fixed bracket 66. Supported by the driving rod 68, the fixed bracket 66 moves towards the inner wall of the coal conveying pipeline 2 until the cleaning brush 67 fits against the pipe wall. By controlling the rotation of the rotating rod 62 through the first motor 61, the cleaning brush 67 is driven to rotate, so that the cleaning brush 67 scrapes off the pulverized coal adhering to the inner wall of the coal conveying pipeline 2, preventing the accumulation of pulverized coal.

[0026] One end of the coal conveying pipeline 2 close to the storage cylinder 3 is provided with an extension block 21. A threaded hole 22 is opened inside the extension block 21.

A sleeve column 634 is movably sleeved on the outside of the lead screw 632. A slide bar 635 is movably penetrated through the inside of the sleeve column 634. Both ends of the slide bar 635 are respectively installed on the stop block 633 and the rotating rod 62. A bearing 636 is sleeved on the outside of the sleeve column 634. A moving ring 64 is sleeved on the outside of the bearing 636. By controlling the rotation of the lead screw 632 by the second motor 631, the sleeve column 634 drives the moving ring 64 to move towards the rotating rod 62. The moving ring 64 pushes the movable rod 65, so that the fixing bracket 66 on the movable rod 65 moves towards the inner wall of the coal conveying pipe 2, and the cleaning brush 67 fits against the pipe wall.

[0029] On one side of the fixed sleeve 69 close to the mounting block 4, a scraper 7 is provided. The scraper 7 is rotatably sleeved on the outside of the rotating rod 62. The scraper 7 fits against the inner wall of the coal conveying pipe 2. The movement of the scraper 7 can take away the pulverized coal accumulated in the pipe. On one side of the scraper 7 close to the mounting block 4, an electric push rod 8 is provided. One end of the electric push rod 8 away from the scraper 7 is arranged on the mounting block 4. Positioning telescopic rods 9 are connected to the scraper 7 on both sides of the electric push rod 8. One end of the positioning telescopic rod 9 away from the scraper 7 is arranged on the mounting block 4. The positioning telescopic rod 9 makes the movement of the scraper 7 more stable. By pushing the scraper 7 to move inside the coal conveying pipe 2 by the electric push rod 8, the pulverized coal cleaned by the cleaning brush 67 is taken away to avoid the loss caused by the accumulation of pulverized coal.

[0030] Working principle: First, pulverized coal is conveyed into the coal conveying pipe 2 through the coal feeding port 5. The coal conveying pipe 2 is in an inclined state to facilitate the pulverized coal to enter the smelting furnace 1. By controlling the rotation of the lead screw 632 by the second motor 631, the sleeve column 634 drives the moving ring 64 to move towards the rotating rod 62. The moving ring 64 pushes the movable rod 65, so that the fixing bracket 66 on the movable rod 65 moves towards the inner wall of the coal conveying pipe 2, and the cleaning brush 67 fits against the pipe wall. By controlling the rotation of the rotating rod 62 by the first motor 61, the cleaning brush 67 is driven to rotate, so that the cleaning brush 67 scrapes off the pulverized coal attached to the inner wall of the coal conveying pipe 2. By pushing the scraper 7 to move inside the coal conveying pipe 2 by the electric push rod 8, the pulverized coal cleaned by the cleaning brush 67 is taken away to avoid the loss caused by the accumulation of pulverized coal.

[0031] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention.
