Description

Technical Field

[0001] This utility model relates to the field of aluminum slag smelting technology, specifically to an aluminum slag secondary smelting furnace feeding and conveying device. Background Technology

[0002] Aluminum slag is an impure mixed metal slag produced during aluminum smelting, but it still contains a certain amount of aluminum. Some aluminum can be separated and refined. The smelting of aluminum slag requires the use of a smelting furnace. During this process, a conveying device is needed to complete the multiple conveying of aluminum liquid and ensure that the smelting furnace can fully melt the filter slag in the aluminum liquid. In actual use, it has the advantages of simple operation, stable structure and good performance.

[0003] The prior art discloses a high-efficiency smelting device for waste aluminum with application number CN201820203714.6. In the above-mentioned utility model, the return liquid pipeline, the return liquid pump and the liquid guide pipe constitute the aluminum liquid conveying device. When the aluminum liquid passes through the return liquid pipeline, there is no heat preservation structure, which makes it easy for the aluminum liquid to cool down during the conveying process. At the same time, the return liquid pipeline needs to be connected to the smelting furnace and the slag filter box, but there is no auxiliary structure, which makes it difficult to ensure the stability of the connection process. When the connection structure is misaligned, it needs to be realigned, which is cumbersome due to multiple adjustments.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0034] Working principle:

[0035] Before actually using the aluminum slag secondary smelting furnace feeding device, first connect one end of the three-way pipe 7 to the output end of the external liquid pump. Then, connect the external liquid pump, aluminum liquid conveying pump 1, and two sets of electric heating wires 5 to the external control panel via wires. Then, open and close the first valve 8 and the two sets of third valves 12. Using the external control panel, the external liquid pump can be powered on and put into operation. The external liquid pump can inject liquid into the interior of the two sets of protective pipes 4 through the three-way pipe 7. Some of the liquid can enter the interior of the two sets of storage cylinders 18 through the two sets of drain pipes 10. This part of the liquid can push the two sets of piston plates 15 to the right. During this process, the two sets of piston plates 15 can squeeze the four sets of telescopic springs 17. When the two sets of piston plates 15 move to the appropriate position, close the first valve 8. Then, use the external control panel... This stops the external infusion pump. When there is a leak in either of the two sets of protective pipes 4, the four sets of telescopic springs 17, under their own elastic force, can push the two sets of piston plates 15 to the left to reset. When there is no leak in either of the two sets of protective pipes 4, the positions of the two sets of piston plates 15 are fixed. After the test is completed, the two sets of second valves 11 are opened and closed, and the water inside the two sets of protective pipes 4 can be discharged through the two sets of outlet pipes 9. Then, the external control panel is used to start the aluminum liquid transfer pump 1 and the two sets of electric heating wires 5. At this time, the aluminum liquid can be transported through the two sets of liquid guide pipes 2. At the same time, the two sets of electric heating wires 5 heat up to keep the transported aluminum liquid warm. When it is necessary to cool down the two sets of protective pipes 4, the external infusion pump is started using the external control panel, and the first valve 8 and the two sets of second valves 11 are opened and closed, and the water... The liquid can pass through two sets of protective pipes 4, which can then cool the two sets of liquid guide pipes 2 and the two sets of protective pipes 4. The protective pipes 4 have an insulation structure, which can ensure the continuous delivery of high-temperature aluminum liquid, improving the practicality of the aluminum slag secondary smelting furnace feeding device. At the same time, before actually using the aluminum slag secondary smelting furnace feeding device, it is necessary to connect the two sets of flanges 3 to the external smelting furnace and the external slag box. After the connection positions of the two sets of flanges 3 with the external smelting furnace and the external slag box are aligned, the operator moves the two sets of socket plates 6 to the left by hand. When the four sets of suction cups 25 are respectively adsorbed on the outer surface of the external smelting furnace and the external slag box, the two sets of connecting screws 20 and the four sets of connecting nuts 21 on the same side are engaged by the threads. The operator then manually rotates the screws clockwise and counterclockwise. Rotate the four sets of connecting nuts 21 on the same side. When the four sets of connecting nuts 21 on the same side are in close contact with the set of mounting orifice plates 19 on the same side, the alignment and fixing of the two sets of liquid guide pipes 2 is completed. At this time, bolts can be used to connect the two sets of flanges 3 to the external smelting furnace and the external slag box. After the connection is completed, open and close the four sets of fourth valves, and then rotate the four sets of connecting nuts 21 on the same side in the opposite direction. Then move the two sets of socket plates 6 to the left. When the four sets of suction cups 25 are separated from the external smelting furnace and the external slag box, the installation work is completed. When the two sets of socket plates 6 are moved, multiple sets of balls 23 roll inside multiple sets of ball sockets 22. Through the socket plates 6, which have an auxiliary structure, the stability of the alignment connection structure can be guaranteed, which provides a guarantee for the stable alignment connection of the aluminum slag secondary smelting furnace feeding device.
