[0025] Reference Figure 1-3 As shown, a dual-chamber furnace aluminum liquid transfer device includes:

[0026] Furnace body 1, which includes a main chamber 11 and a secondary chamber 14, wherein a transmission channel 2 is provided between the main chamber 11 and the secondary chamber 14, and the main chamber 11 is used to transport heated and molten aluminum liquid to the secondary chamber 14 via the transmission channel 2.

[0027] A filter assembly 3 is disposed on the transmission channel 2, and the filter assembly 3 is used to filter impurities from the molten aluminum on the transmission channel 2.

[0028] A feeding assembly is provided on the transmission channel 2. The feeding assembly includes a pumping component 4 and a feeding well 5. The pumping component 4 is used to pump the filtered aluminum liquid into the feeding well 5.

[0029] The conveying channel 6 is located between the transmission channel 2 and the auxiliary chamber 14. One end of the conveying channel 6 is connected to the outlet 51 of the feeding well 5, and the other end is connected to the liquid inlet 22 of the auxiliary chamber 14. The conveying channel 6 is used to transport the aluminum liquid in the feeding well 5 to the auxiliary chamber 14.

[0030] The main chamber 11 of this invention is used to transport the heated and molten aluminum liquid to the transmission channel 2. The pumping component 4 then pumps the filtered aluminum liquid to the feeding well 5. The transmission channel 6 transports the aluminum liquid in the feeding well 5 to the auxiliary chamber 14. The addition of the transmission channel 6 forms a slag chamber for slag removal, which greatly reduces the number of times the auxiliary chamber 14 needs to be slag removed, avoids temperature loss in the auxiliary chamber 14, and reduces heat loss of the aluminum liquid, thereby ensuring the quality of the processed aluminum liquid. The filter component 3 filters impurities from the aluminum liquid on the transmission channel 2 and can extract aluminum slag for easy cleaning. At the same time, filtering the aluminum liquid can improve the service life of the pumping component 4.

[0031] In one embodiment of the present invention, the conveying channel 6 includes a bottom channel 62 and an upper channel 61 that are interconnected. The bottom channel 62 is connected to the discharge port 51, and the upper channel 61 is connected to the liquid inlet 22. An observation opening is provided on the upper channel 61, and a protective cover is provided on the observation opening.

[0032] Specifically, the upper flow channel 61 is equivalent to adding a slag chamber flow channel at one end for slag removal. The observation opening of the upper flow channel 61 forms an open channel that can be used to remove slag from the slag chamber, which greatly reduces the number of times slag is removed from the secondary chamber 14, avoids temperature loss from the secondary chamber 14, and reduces heat loss from the molten aluminum, thereby ensuring the quality of the molten aluminum after processing. A protective cover is installed on the observation opening to prevent temperature loss from the upper flow channel 61 and ensure processing safety.

[0033] In one embodiment of the present invention, the filter assembly 3 includes a filter frame 31, which is disposed on the transmission channel 2. A filter plate 32 is disposed on the filter frame 31, and the filter plate 32 has filter holes 33.

[0034] Specifically, after the main chamber 11 heats and melts the aluminum material into molten aluminum, the molten aluminum flows into the feed end 21 of the transmission channel 2. The molten aluminum is filtered through the filter holes 33 on the filter plate 32. The aluminum slag is filtered and remains on the filter plate 32 and the surface of the transmission channel 2. When it accumulates to a certain weight, the slag can be directly removed from the open channel on the transmission channel 2, making it easy to clean. At the same time, filtering the molten aluminum can improve the service life of the pump feeder 42.

[0035] In one embodiment of the present invention, the filter frame 31 is disposed on the feed end 21 of the transmission channel 2, the feed end 21 of the transmission channel 2 is connected to the liquid outlet 44 of the main chamber 11, and the two inner sidewalls of the transmission channel 2 are provided with fixing slots 34, and the two ends of the filter frame 31 are fixed in the fixing slots 34.

[0036] Specifically, multiple sets of fixing slots 34 can be set on the two inner side walls of the transmission channel 2, so that another filter plate 32 can be installed at the same time to facilitate the replacement of the filter plate 32 that needs to be cleaned. Alternating replacement can achieve uninterrupted processing and high processing efficiency.

[0037] In one embodiment of this utility model, the pumping component 4 includes a pump well 41 and a pump feeder 42. The pump feeder 42 can be a centrifugal pump or other equipment used for pumping aluminum liquid. The pump well 41 is disposed in the transmission channel 2. A pumping frame 43 is disposed on the transmission channel 2. The pump feeder 42 is disposed on the pumping frame 43. A liquid outlet 44 is disposed on the pump well 41. The liquid outlet 44 is connected to the feeding well 5.

[0038] Specifically, after being filtered, the molten aluminum flows into the pump well 41. The outlet 44 on the pump well 41 is connected to the top of the feeding well 5. The pump feeder 42 pumps the molten aluminum into the feeding well 5, which can quickly transfer the molten aluminum.

[0039] In one embodiment of the present invention, the feeding well 5 has a cone-shaped structure, the discharge port 51 is located at the bottom of the feeding well 5, and the liquid outlet 44 on the pump well 41 is connected to the top of the feeding well 5.

[0040] In one embodiment of this utility model, the liquid outlet 44 is tangent to the top circumference of the feeding well 5, so that the aluminum liquid pumped out by the pump feeder 42 forms a spiral downward vortex along the inner wall of the feeding well 5.

[0041] Specifically, the pump 42 pumps the molten aluminum into the feeding well 5 along the top circumference tangentially, so that the pumped molten aluminum forms a downward spiral vortex along the inner wall of the feeding well 5 and is transported into the conveying channel 6. The downward spiral vortex can be understood as the form of a toilet flushing, which can accelerate the flow rate of the molten aluminum and quickly discharge the molten aluminum into the conveying channel 6.

[0042] In one embodiment of this utility model, the liquid inlet 22 and the discharge outlet 51 are at the same height, and the liquid level in the upper flow channel 61 is higher than the liquid level in the feeding well 5 and the auxiliary chamber 14.

[0043] Specifically, since the inlet 22 and the outlet 51 are at the same height, the liquid level in the upper flow channel 61 is higher than that in the feeding well 5 and the secondary chamber 14. This allows the observation opening of the upper flow channel 61 to be used for slag removal in the slag chamber, greatly reducing the number of times slag is removed from the secondary chamber 14, preventing temperature loss in the secondary chamber 14, and reducing heat loss from the aluminum liquid, thereby ensuring the quality of the processed aluminum liquid.

[0044] In one embodiment of the present invention, a baffle plate 63 is provided on the bottom surface of the upper flow channel 61, and a guide slope 64 is provided at both ends of the baffle plate 63. The height of the baffle plate 63 is greater than or equal to the height of the liquid inlet 22.

[0045] Specifically, a baffle plate 63 is provided on the bottom surface of the upper flow channel 61. The height of the baffle plate 63 is greater than or equal to the height of the liquid inlet 22, so that it can turbulent and slow down the flow of the convective aluminum liquid, so that the waste residue in the aluminum liquid flows to the observation opening of the upper flow channel 61 to remove some of the aluminum slag. The baffle plate 63 is provided with guide slopes 64 at both ends, which can make the aluminum liquid flow more smoothly and can make the aluminum liquid and aluminum slag form a certain speed difference to ensure the separation of aluminum slag.

[0046] This utility model also includes a method for transferring molten aluminum in a dual-chamber furnace. The method uses the aforementioned molten aluminum transfer device and includes the following steps: the main chamber 11 heats and melts the aluminum material and then transfers the molten aluminum to the transfer channel 2. The filter assembly 3 on the transfer channel 2 filters the molten aluminum and then transfers it to the pumping component 4. The pumping component 4 pumps the molten aluminum along the top circumference of the feeding well 5 tangentially into the feeding well 5, so that the pumped molten aluminum forms a spiral downward vortex along the inner wall of the feeding well 5 and is transferred to the conveying channel 6. The conveying channel 6 then transfers the molten aluminum after slag removal to the auxiliary chamber 14 to complete the molten aluminum transfer.

[0047] Usage process

[0048] The main chamber 11 is equipped with an existing feeding door 13 and a heating and combustion system 12. The feeding door 13 is used to add aluminum and remove slag, while the heating and combustion system 12 is used to heat and melt the aluminum to form molten aluminum. The auxiliary chamber 14 is connected to an existing molten aluminum discharge device 15 for discharging the molten aluminum. After the aluminum is heated and melted into molten aluminum in the main chamber 11, the molten aluminum flows into the feed end 21 of the transmission channel 2. The molten aluminum is filtered through the filter holes 33 on the filter plate 32. The aluminum slag is filtered and remains on the filter plate 32 and the surface of the transmission channel 2. When it accumulates to a certain weight, the slag can be directly removed from the open channel on the transmission channel 2 for easy cleaning. Multiple sets of fixing slots 34 can be set on the two inner side walls of the transmission channel 2 to install another filter plate 32 at the same time, making it convenient to replace the filter plate 32 that needs to be cleaned. Alternating replacement can achieve uninterrupted processing and high processing efficiency. After filtration, the molten aluminum flows into the pump well 41. Inside, the outlet 44 on the pump well 41 is connected to the top of the feeding well 5. The pump feeder 42 pumps the molten aluminum along the top circumference of the feeding well 5 tangentially into the feeding well 5, causing the pumped molten aluminum to form a downward spiral vortex along the inner wall of the feeding well 5 and be transported into the conveying channel 6. The downward spiral vortex can be understood as a flushing motion similar to a toilet, which can accelerate the flow rate of the molten aluminum and quickly discharge it into the conveying channel 6. One end of the conveying channel 6 is connected to the outlet of the feeding well 5. The upper channel 61 is connected to the inlet 51, and the other end is connected to the liquid inlet 22 of the auxiliary chamber 14. Since the liquid inlet 22 and the outlet 51 are at the same height, the liquid level of the upper channel 61 is higher than that of the feeding well 5 and the liquid level in the auxiliary chamber 14. This allows the observation opening of the upper channel 61 to be used for slag removal in the slag chamber, greatly reducing the number of times the auxiliary chamber 14 needs to be removed, avoiding temperature loss in the auxiliary chamber 14, and reducing heat loss of the aluminum liquid, thereby ensuring the quality of the aluminum liquid after processing.
