[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which the present invention pertains. The terms used herein in the present specification are intended only to describe the purpose of a specific embodiment and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0028] like Figure 1 , Figure 2 As shown, an electromagnetic propulsion furnace external circulation and transmission device includes two chambers in a double-chamber smelting furnace 1, and holes are provided at the bottom of the partition wall between the main chamber hot chamber and the auxiliary chamber cold chamber for the flow of molten metal;

[0029] The external chute circulation group includes: main chamber connected circulation chute 2, circulation transition chute 1 3, circulation right angle chute 4, circulation transition chute 2 5, circulation three-way chute 7, auxiliary chamber connected circulation chute 9, and small discharge chute 8;

[0030] The main chamber hot chamber of the double-chamber smelting furnace 1 is connected to the main chamber through the circulating chute 2 to form a circulating flow channel, the main chamber is connected to the circulating chute 2 and the circulating transition chute 3 to form a circulating flow channel, the circulating transition chute 3 is connected to the circulating right-angle chute 4 to form a circulating flow channel, the circulating right-angle chute 4 is connected to the circulating transition chute 2 5 to form a circulating flow channel, the circulating transition chute 2 5 is connected to the circulating three-way chute 7 to form a circulating flow channel, the circulating three-way chute 7 is connected to the auxiliary chamber through the circulating chute 9 to form a circulating flow channel, and the auxiliary chamber is connected to the circulating chute 9 and the auxiliary chamber cold chamber of the double-chamber smelting furnace 1 to form a circulating flow channel.

[0031] In this embodiment, the molten metal melted in the double-chamber smelting furnace 1 is at the same level in the two chambers of the double-chamber smelting furnace 1 and in the chute circulation group outside the furnace.

[0032] like Figure 4 As shown, the circulating three-way chute 7 is connected with the small discharging chute 8 to form a discharging flow channel, and the discharging flow channel is higher than the circulating flow channel.

[0033] like Figure 3 As shown, the electromagnetic propeller 6 is placed in the tunnel at the bottom of the circulating transition chute 2 5. The electromagnetic propeller 6 applies a driving force to the molten metal in the flow channel of the circulating transition chute 2 5. Due to the effect of atmospheric pressure, the liquid in the circulating chute group and the double-chamber smelting furnace circulates as a whole to realize the out-of-furnace circulation function.

[0034] like Figure 1 Figure 2 As shown, when discharging is required, the small discharging chute gate valve 10 placed inside the small discharging chute 8 is opened, and the circulating chute gate valve 11 placed inside the auxiliary chamber connecting the circulating chute 9 is closed. Since the electromagnetic propeller 6 placed at the bottom of the circulating transition chute 2 5 cuts off the flow channel connecting the auxiliary chamber connecting the circulating chute 9 and the auxiliary chamber cold chamber of the double-chamber smelting furnace 1, it continuously applies a driving force to the molten metal, causing the liquid level in the circulating flow channel of the circulating transition chute 2 5 and the circulating three-way chute 7 to continue to rise, and then the molten metal in the flow channel flows out along the discharging flow channel formed by the circulation three-way chute 7 and the small discharging chute 8 to realize the transmission function.

[0035] In this embodiment, a high liquid level warning device 12 is provided on the top of the circulating transition chute 2 5. When the molten metal level reaches a set high liquid level, the power output of the electromagnetic propeller 6 is reduced or stopped to achieve safety and control.

[0036] In this embodiment, a circulating chute cover plate 13 is provided on the top of the external chute circulation group to play a heat preservation function, reduce the diffusion of the temperature of the molten metal in the air, and play an energy-saving function.

[0037] In the present invention, a double-chamber melting furnace 1 is divided into a main chamber (hot chamber) and a sub-chamber (cold chamber). Solid metal is added to the sub-chamber (cold chamber) without burning, and the main chamber (hot chamber) is a combustion chamber without adding solid metal. There are holes at the bottom of the partition wall between the main chamber and the sub-chamber, so that the molten metal can smoothly pass through the partition wall to form a flow channel. The main chamber of the double-chamber melting furnace 1 is connected to the main chamber with the circulating chute 2 to form a circulating flow channel, the main chamber is connected to the circulating chute 2 and the circulating transition chute 3 to form a circulating flow channel, and the circulating transition chute 3 is connected to the circulating right-angle chute 4 to form a circulating flow channel. The circulation right-angle chute 4 is connected with the circulation transition chute 2 5 to form a circulation flow channel, the circulation transition chute 2 5 is connected with the circulation three-way chute 7 to form a circulation flow channel, the circulation three-way chute 7 is connected with the auxiliary chamber to the circulation chute 9 to form a circulation flow channel, and the auxiliary chamber is connected with the circulation chute 9 and the auxiliary chamber cold chamber of the double-chamber smelting furnace 1 to form a circulation flow channel; the electromagnetic propeller 6 is placed in the lane at the bottom of the circulation transition chute 2 5, and the electromagnetic propeller 6 applies a driving force to the molten metal in the flow channel of the circulation transition chute 2 5, so that the molten metal flows rapidly along the circulation flow channel;

[0038] When discharging is required, the gate valve 10 of the small discharging chute 8 is opened, and the gate valve 11 of the circulating chute 9 connected to the auxiliary chamber is closed. Since the electromagnetic propeller 6 at the bottom of the circulating transition chute 2 5 cuts off the flow channel connecting the auxiliary chamber and the circulating chute 9 with the auxiliary chamber cold chamber of the double-chamber smelting furnace 1, it continuously applies a driving force to the molten metal, causing the liquid level in the circulating flow channel of the circulating transition chute 2 5 and the circulating three-way chute 7 to continuously rise, and then the molten metal in the flow channel flows out along the discharging flow channel formed by the circulation three-way chute 7 and the small discharging chute 8 to realize the transmission function.

[0039] The above is a detailed introduction to an electromagnetic propulsion furnace external circulation and transmission device provided by the present invention.
