An embedding groove 13 is formed on the bottom side wall of the mold inner shell 12, and a heating wire 14 is installed in the embedding groove 13 by embedding. The heating wire 14 is installed in the embedding groove 13 by embedding, which improves the efficiency of heat generated by the heating wire 14 being transferred through the mold inner shell 12.

[0032] Preferably, the mold outer shell 11 is made of cast iron material, and the mold inner shell 12 is made of boron nitride ceramic material. Since the boron nitride material has excellent heat conduction performance, and since the heating wire 14 is installed on the mold inner shell 12 by embedding, the heat generated by the heating wire 14 can be efficiently transferred through the mold inner shell 12, thereby efficiently drying the aluminum ash in the mold inner shell 12.

[0033] As shown in Figure 3 and Figure 4 , the fin 15 is provided in an L shape, and the two wall plates of the fin 15 in the L shape are fixedly connected to the side wall and the bottom wall plate of the mold inner shell 12, so that the fin 15 can quickly transfer heat.

The heat insulation layer 17 is arranged close to the mold outer shell 11 and is used to insulate the heat in the cavity to avoid heat transfer to the mold outer shell 11, thereby avoiding heat loss through the mold outer shell 11. At the same time, the heat insulation layer 17 can reflect heat, so that the heat is reflected to the surface of the mold inner shell 12 for transmission, thereby making the heat can be efficiently utilized, and further reducing the waste of heat.

[0035] As shown in Figure 4 , a maintenance opening 18 is formed on the bottom wall plate of the mold outer shell 11, and the maintenance opening 18 is used for maintaining the components in the cavity. A cover plate 19 is installed on the maintenance opening 18, and the cover plate 19 is used to block the maintenance opening 18.

[0037] As shown in Figure 1 , Figure 2 and Figure 5 , the air exhaust assembly 2 comprises an air exhaust cover 21 arranged above the mold inner shell 12. The air exhaust cover 21 is used to adsorb and treat the gas generated when the aluminum dross in the mold inner shell 12 is dried. A fixed plate 23 is installed above the air exhaust cover 21, and the fixed plate 23 is fixedly installed on the corresponding connecting piece to ensure the position of the fixed plate 23. An adjusting screw 24 is threadedly connected to the fixed plate 23 in a penetrating manner, so that the adjusting screw 24 can move up and down on the fixed plate 23 by rotating. The lower end of the adjusting screw 24 is connected with the air exhaust cover 21, and the air exhaust cover 21 can be moved up and down by adjusting the movement of the adjusting screw 24, thereby adjusting the distance between the air exhaust cover 21 and the mold inner shell 12.

[0038] As shown in Figure 1 and Figure 5As shown, the upper end of the air suction hood 21 is provided with a negative pressure pipe 22, which is connected to a negative pressure device, so that the air suction hood 21 can suck the harmful gas generated during the drying of the aluminum dross for treatment. The negative pressure pipe 22 is provided as an extendable bellows, so that the negative pressure pipe 22 can move with the air suction hood 21 when the air suction hood 21 moves.

By rotating the adjusting screw 24 in the bearing 25, the adjusting screw 24 can drive the air suction hood 21 to move up and down. The upper end of the adjusting screw 24 is fixedly connected with a rotating block 26, which makes the rotation of the adjusting screw 24 more convenient.

[0040] As shown in Figure 1 , Figure 2 and Figure 5 , the fixed plate 23 is slidably connected with a limiting rod 27 in a penetrating manner, and the fixed plate 23 is provided with a sliding hole for connecting the limiting rod 27.

[0041] As shown in Figure 1 and Figure 5 , the lower end of the limiting rod 27 is fixedly connected to the air suction hood 21, and the upper end of the limiting rod 27 is fixedly connected with a limiting block 28. When the adjusting screw 24 drives the air suction hood 21 to move up and down, the movement of the air suction hood 21 will drive the limiting rod 27 to move, and through the cooperation between the limiting rod 27 and the fixed plate 23, the air suction hood 21 can move stably up and down.

[0042] In use, the aluminum dross to be dried is placed in the inner shell 12 of the mold, and the heating wire 14 can generate heat through the power cord 111 and the power supply connection. The heat of the heating wire 14 can be quickly transmitted through the inner shell 12 of the mold, so as to dry the aluminum dross in the inner shell 12 of the mold. At the same time, the heat is assisted by the plurality of fins 15, so that the heat is more uniformly transmitted to the inner shell 12 of the mold. At the same time, the heat in the cavity is reflected to the inner shell 12 of the mold by the heat reflecting layer 16 for repeated use, reducing the loss of heat and improving the efficiency of drying the aluminum dross. When the aluminum dross is dried, the distance between the air suction hood 21 and the inner shell 12 of the mold is adjusted by rotating the adjusting screw 24, so that the air suction hood 21 can recover and treat the harmful gas generated by the aluminum dross through the negative pressure provided by the negative pressure pipe 22.
