Description

Technical Field

[0001] This utility model relates to a slag conveying device for aluminum melting furnaces that can improve conveying efficiency, and belongs to the field of slag conveying technology. Background Technology

[0002] The aluminum melting furnace is a new type of high-efficiency and energy-saving furnace developed based on the aluminum smelting process. It can well meet the requirements of strict alloy composition, discontinuous production, and large single furnace capacity in the aluminum smelting process. It achieves the effects of reducing consumption, reducing burn-off, improving product quality, reducing labor intensity, improving working conditions, and increasing production efficiency. It is suitable for intermittent operation and smelting with a lot of alloys and recycled materials. Its characteristics are high efficiency and energy saving, high thermal efficiency, stability and reliability, low carbon and environmental protection, and simple operation.

[0003] The existing patent number CN212702133U describes a slag conveying device for an aluminum melting furnace. This device uses a crushing roller inside the crushing box to crush the slag for easy conveying. An inclined screen plate below the crushing roller filters the crushed slag, and slag that does not meet the conveying requirements is discharged through the outlet. A spiral blade inside the conveying cylinder transports the slag by rotating, and the spiral blade can also agitate and crush the slag, improving conveying efficiency. However, this device may not be suitable for conveying slag as it may contain lumps of slag that splash during crushing. Direct discharge is not reliable, as it cannot fully crush the slag and wastes resources. Furthermore, when using an inclined screen plate for slag screening, fragments and substandard slag can clog the screen holes, affecting slag discharge and requiring manual cleaning, thus impacting machine operation and reducing slag transport efficiency.

[0013] The beneficial effects of this utility model are:

[0014] This invention utilizes a feeding hopper to feed slag into a transfer box. A drive motor rotates the crushing rollers to crush the slag. An arc-shaped screen intercepts slag that is not properly crushed. A slow-speed motor rotates a rotating disc that drives a transmission bolt, causing the driven rail plate to swing back and forth along a transmission block and a pushing scraper. This allows the pushing scraper to re-feed the intercepted slag, enabling secondary crushing. A baffle prevents slag splashing, reducing energy waste. The slow-speed motor also rotates a sprocket assembly, which in turn rotates a cam. This cam causes the transmission rollers to move the sliding frame downwards. When the cam's raised end rotates upwards, a spring extends, causing a striking block to automatically strike the arc-shaped screen, preventing slag blockage and ensuring continuous slag transport, thus improving slag conveying efficiency.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please refer to Example 1 Figures 1-5 This utility model provides a technical solution:

[0024] A slag conveying device for an aluminum melting furnace that improves conveying efficiency includes a transfer box 1, a conveying pipe 10, and a feed hopper 12. A crushing roller 2 is rotatably connected to the upper inner side of the transfer box 1. A baffle 3 is provided on the outer side of the crushing roller 2, and the baffle 3 is fixedly connected to the transfer box 1. An arc-shaped screen plate 4 is fixedly connected to the inner lower end of the baffle 3, and a pushing scraper 5 is slidably connected to the inner side of the baffle 3. The pushing scraper 5 is slidably connected to the arc-shaped screen plate 4 and rotatably connected to the transfer box 1. The feed hopper 12 is sealed to the upper end of the transfer box 1. A drive motor 13 is fixedly connected to the left end of the transfer box 1, and the output shaft of the drive motor 13 is fixedly connected to the crushing roller 2. A vacuum cleaner 14 is sealed to the upper front end of the transfer box 1. A fixing frame 15 is fixedly connected to the right end of the transfer box 1. A slow-speed motor 16 is fixedly connected to the upper right end of the fixing frame 15. A rotating disc 17 is fixedly connected to the left end of the output shaft of the slow-speed motor 16, and the rotating disc 17 rotates with the fixing frame 15. The rotating disc 17 is connected to a transmission bolt 18 fixedly on the upper left side. A driven rail plate 19 is slidably connected to the outer side of the transmission bolt 18. The driven rail plate 19 is rotatably connected to the fixed frame 15. A transmission block 20 is fixedly connected to the lower left end of the driven rail plate 19. The transmission block 20 is fixedly connected to the push scraper 5. The slag can be fed into the transfer box 1 by the feeding hopper 12. The rotation of the drive motor 13 enables the crushing roller 2 to crush the slag. The arc screen plate 4 can intercept the slag that is not crushed properly. The rotation of the slow motor 16 enables the rotating disc 17 to drive the transmission bolt 18 to rotate. This causes the driven rail plate 19 to drive the transmission block 20 and the push scraper 5 to swing back and forth. This allows the push scraper 5 to feed the intercepted slag a second time, enabling the slag to be crushed a second time. The baffle 3 can prevent slag from splashing, thereby reducing energy waste.

[0025] Please refer to Example 2 Figure 2 and Figure 4The difference between this embodiment and Embodiment 1 is as follows: a fixed plate 6 is fixedly connected to the lower side of the interior of the transfer box 1; a sliding frame 7 is slidably connected to the inner side of the fixed plate 6; a striking block 8 is fixedly connected to the upper end of the sliding frame 7; a guide pipe 9 is sealed and connected to the middle position of the lower end of the transfer box 1; a conveying pipe 10 is sealed and connected to the lower end of the guide pipe 9; an auger conveying rod 11 is rotatably connected inside the conveying pipe 10; a sprocket assembly 21 is rotatably connected to the right side of the interior of the fixed frame 15; the upper sprocket of the sprocket assembly 21 is fixedly connected to the rotating disc 17; a cam 22 is fixedly connected to the left end of the lower sprocket of the sprocket assembly 21; the cam 22 is rotatably connected to the transfer box 1; and the upper left and right sides of the lower plate of the sliding frame 7 are rotatably connected to... There is a transmission roller 23, which is rolledly connected to the cam 22. The upper rod of the sliding frame 7 is covered with a spring 24. The left end of the conveying pipe 10 is fixedly connected to the feeding motor 25. The output shaft of the feeding motor 25 is fixedly connected to the auger conveying rod 11. The rotation of the slow motor 16 causes the sprocket group 21 to rotate simultaneously, thereby causing the cam 22 to rotate. This causes the transmission roller 23 to drive the sliding frame 7 to move downward. When the cam 22 rotates upward, the spring 24 can extend, thereby causing the striking block 8 to automatically strike the arc screen plate 4, preventing slag from clogging the screen holes and affecting the continuous conveying of slag, thus improving the conveying efficiency of slag.

[0026] The working principle of this utility model is as follows: In use, the feeding hopper 12 feeds slag into the transfer box 1. The rotation of the drive motor 13 causes the crushing roller 2 to crush the slag. The arc-shaped screen plate 4 intercepts slag that is not properly crushed. The rotation of the slow-speed motor 16 causes the rotating disk 17 to drive the transmission bolt 18, which in turn causes the driven rail plate 19 to drive the transmission block 20 and the pushing scraper 5 to swing back and forth. This allows the pushing scraper 5 to crush the intercepted slag. Secondary feeding allows for secondary crushing of the slag, while the baffle 3 prevents slag from splashing, thus reducing energy waste. The rotation of the slow-speed motor 16 causes the sprocket assembly 21 to rotate simultaneously, which in turn causes the cam 22 to rotate. This, in turn, causes the transmission roller 23 to drive the sliding frame 7 to move downward. When the cam 22 rotates upward at its protruding end, the spring 24 extends, allowing the striking block 8 to automatically strike the arc-shaped screen plate 4, preventing slag from clogging the screen holes and affecting the continuous conveying of slag, thereby improving the conveying efficiency of slag.
