[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0022] Example: Please refer to Figure 1 This utility model provides a technical solution: a circulating heat preservation device for aluminum scrap furnace.

[0023] The furnace 1 is equipped with a flip-top 2, a feed inlet 3 at the bottom of the flip-top 2, an aluminum chip tray 6 below the feed inlet 3, a conical hole 18 on the surface of the aluminum chip tray 6, a heating base 7 at the bottom of the aluminum chip tray 6, multiple vertical flow channels 8 inside the heating base 7, a heating area 17 on the side of the heating base 7, a flow guide base 9 at the bottom of the heating base 7, an inclined flow channel 10 inside the flow guide base 9, flow guide plates 11 on both sides of the heating base 7, a heat preservation pipe 13 below the flow guide plate 11, a liquid storage tank 14 at the bottom of the heat preservation pipe 13, and a liquid outlet 15 at the center of the bottom of the liquid storage tank 14.

[0024] In this embodiment, the entire furnace 1 generates heat through the heating components in the heating zone 17, which in turn heats the heating base 7. The flip cover 2 is opened and aluminum chips are poured in. The aluminum chips accumulate on the aluminum chip tray 6. The heating base 7 transfers heat to the aluminum chip tray 6, melting the aluminum chips on the aluminum chip tray 6. The aluminum chips turn into molten aluminum and flow through the conical hole 18. Then, it passes through the vertical flow channel 8 and enters the guide base 9. The vertical flow channels 8 are connected by the inclined flow channel 10. The molten aluminum flows out from the guide base 9 from the side inclined flow channel 10 and meets at the guide plate 11. Then, it flows into the heat preservation pipe 13 from the connecting hole 12 to maintain the flow of molten aluminum. Finally, it enters the storage tank 14 for collection and storage. When needed, the stored molten aluminum can be taken out from the liquid outlet 15. After heating, impurities in the aluminum chips cannot be melted and remain on the aluminum chip tray 6. The aluminum chip tray 6 can be directly removed to clean the impurities. Some unmelted impurities will remain in the conical hole 18, which facilitates subsequent cleaning and prevents impurities from flowing into the vertical flow channel 8.

[0025] The flip cover 2 has a fan 5 installed inside, the top of the fan 5 has a motor 4, and the side wall of the furnace 1 has an insulation layer 16.

[0026] In this embodiment, the fan 5 is driven by the motor 4 to blow the heat generated and overflowing from the heating base 7, causing it to circulate inside the insulation layer 16, ensuring that the bottom insulation pipe 13 can also maintain a high temperature, and the temperature in all parts of the furnace 1 is stable. The insulation layer 16 reduces the loss of internal temperature, thereby reducing energy consumption.

[0027] The furnace 1 has a plate-removing opening 21 on the front, a guide rail 22 on the outside of the plate-removing opening 21, a baffle 23 installed inside the guide rail 22, a hanging ring 24 on the front of the baffle 23 near the top, and a hook 25 on the top of the plate-removing opening 21.

[0028] In this embodiment, the take-out port 21 is closed when the furnace 1 is heated. After heating is completed, the processing baffle 23 is pushed upward along the guide rail 22, and the hanging ring 24 is hung on the hook 25 to hook the baffle 23, ensuring that the take-out port 21 is in a normally open state, so that the operator can easily take the aluminum chip tray 6 out of the furnace 1.

[0029] Among them, a clamping block 19 is fixedly connected to the center of the front end of the aluminum chip tray 6, and buckles 20 are fixedly connected to the left and right sides of the front end of the aluminum chip tray 6.

[0030] In this embodiment, after the aluminum chip tray 6 is heated inside the furnace 1, a large amount of heat remains and it is very hot. The aluminum chip tray 6 can be removed from the heating base 7 by clamping the area of ​​the clamping block 19 with a clamping tool to avoid contact with the high temperature aluminum chip tray 6. When installing the aluminum chip tray 6, the buckle plate 20 is aligned with the notch on the heating base 7 and fastened to install the aluminum chip tray 6 on the heating base 7. The conical hole 18 can be aligned with the vertical flow channel 8 to ensure that the flow of molten aluminum does not leak.

[0031] Among them, the bottom of the furnace 1 is equipped with support feet 26 at the four corners.

[0032] In this embodiment, the support foot 26 lifts and supports the entire furnace 1, while simultaneously freeing up the liquid extraction port 15 for easy liquid extraction.

[0033] Working principle: The aluminum chip tray 6 is installed on the heating base 7 beforehand. The flip cover 2 is opened and aluminum chips are poured into the aluminum chip tray 6. The heating base 7 is heated by the heating component to start melting the aluminum chips. The aluminum chips turn into molten aluminum and enter the vertical flow channel 8 through the conical hole 18 and then enter the guide base 9. Then, it flows out from the guide base 9 through the side inclined flow channel 10, flows through the connection hole 12 and into the heat preservation pipe 13, and finally enters the storage tank 14 for collection and storage. The motor 4 drives the fan 5 to keep the internal temperature of the furnace 1 uniform. After heating is completed, the tray opening 21 can be opened to remove the aluminum chip tray 6 for impurity cleaning.

[0034] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
