[0021] The present invention will be further described in detail below with reference to specific embodiments.

[0022] like Figure 1 The aluminum melting furnace shown has a feed inlet 2 on the upper rear side of the furnace body 1. Aluminum material enters the furnace body 1 through the feed inlet 2 and is heated and melted into aluminum liquid.

[0023] like Figure 2 As shown, a cement base 8 is provided at the furnace bottom 10, with its front extending outside the furnace body 1. Figure 3 and Figure 4The furnace body 1 has an aluminum molten material outlet 30 on the left and a bottom material outlet 40 on the right at the lower front side. The aluminum molten material outlet 30 is equipped with an aluminum molten material gate 5, and the bottom material outlet 40 is equipped with a bottom material gate 6. The lower edge of the aluminum molten material outlet 30 is higher than the furnace bottom 10, and the lower edge of the bottom material outlet 40 reaches the furnace bottom 10. The base 8 has an aluminum molten material flow channel 3 at the front corresponding to the aluminum molten material outlet 30, and a bottom material flow channel 4 at the bottom material outlet 40.

[0024] When it is necessary to remove molten aluminum, operate to open molten aluminum gate 5, such as... Figure 3 As shown, molten aluminum flows out through the molten aluminum outlet 30 and then through the molten aluminum flow channel 3. The side wall of the molten aluminum flow channel 3 is inclined, allowing the molten aluminum on the wall to naturally flow to the bottom of the channel. After the material is collected, the molten aluminum gate 5 is closed. The bottom material gate 6 remains closed, so the molten aluminum in the furnace body below the lower edge of the molten aluminum outlet 30 will not be completely drained, and the furnace body 1 will not be damaged by dry burning. The molten aluminum gate 5 is hinged with a first handle 51. Pulling the first handle 51 upwards moves the molten aluminum gate 5 upwards along the first track 52 to open the molten aluminum gate 5; pressing the first handle 51 downwards moves the molten aluminum gate 5 downwards along the first track 52 to close the molten aluminum gate 5.

[0025] When it is necessary to drain the molten aluminum from the bottom of the furnace (10), open the bottom material gate (6). Figure 4 As shown, the molten aluminum at the furnace bottom 10 can flow out through the bottom material outlet 40 and then through the bottom material flow channel 4. Figure 2 As shown, the furnace bottom 10 is inclined, guiding the molten aluminum in the furnace bottom 10 towards the bottom material outlet 40. After the molten aluminum in the furnace bottom 10 is emptied, the bottom material gate 6 is closed. To prevent the bottom material gate 6 from being accidentally opened to empty the molten aluminum in the furnace body 1 and damaging the furnace body 1, the bottom material gate 6 is equipped with a safety locking structure as follows: the bottom material gate 6 is hinged to a second handle 61, such as... Figure 6 As shown, the second handle 61 has a limit hole 631, and a locking block with a locking hole 632 protrudes from the outer wall of the furnace body 1. The locking bolt 630 passes through the locking hole 632 and is inserted into the limit hole 631 to fix the second handle 61, preventing the second handle 61 from being accidentally pulled open by the bottom material gate 6 to drain the aluminum liquid in the furnace body 1 and damage the furnace body 1. See Figure 7 When it is necessary to open the bottom material gate 6, the locking bolt 630 must be pulled out before the second handle 61 can be pulled upward to move the bottom material gate 6 upward along the second track 62 to open the bottom material outlet 40. When it is necessary to close the bottom material gate 6, the second handle 61 should be pressed down to move the bottom material gate 6 downward along the second track 62 to close the bottom material gate 6. Then, the locking bolt 630 should be inserted into the locking hole 632 and the limit hole 631 to fix the second handle 61.

[0026] like Figure 1As shown, the base 8 is provided with a first platform 81 at the left side of the aluminum liquid channel 3, a second platform 82 between the aluminum liquid channel 3 and the bottom material channel 4, and a third platform 83 at the right side of the bottom material channel 4. The first platform 81 is wider than the second platform 82, and the third platform 83 is also wider than the second platform 82. A footboard 9 for the worker to walk on is hinged on the second platform 82. When the worker walks from the first platform 81 to the third platform 83, the footboard 9 is first laid flat to span above the aluminum liquid channel 3. The worker walks from the first platform 81 to the second platform 82 between the aluminum liquid channel 3 and the bottom material channel 4 via the footboard 9, and then turns the footboard 9 to be placed on the third platform 83 to span above the bottom material channel 4, so as to walk on the third platform 83 over the bottom material channel 4. Figure 5 As shown, the base 8 is provided with a first platform 81 at the left side of the aluminum liquid channel 3, a second platform 82 between the aluminum liquid channel 3 and the bottom material channel 4, and a third platform 83 at the right side of the bottom material channel 4. The first platform 81 is wider than the second platform 82, and the third platform 83 is also wider than the second platform 82. A footboard 9 for the worker to walk on is hinged on the second platform 82. When the worker walks from the first platform 81 to the third platform 83, the footboard 9 is first laid flat to span above the aluminum liquid channel 3. The worker walks from the first platform 81 to the second platform 82 between the aluminum liquid channel 3 and the bottom material channel 4 via the footboard 9, and then turns the footboard 9 to be placed on the third platform 83 to span above the bottom material channel 4, so as to walk on the third
