[0018] See also Figure 1-3The utility model provides a technical solution: a molten aluminum pressing device, including a center pressing plate 2, the center pressing plate 2 is located just above the aluminum melting furnace 1, the center line of the center pressing plate 2 coincides with the center axis of the aluminum melting furnace 1, the upper end of the center pressing plate 2 is provided with a connecting rod 3, one end of the connecting rod 3 is connected to the fixed block 4, the lower end of the fixed block 4 is connected to the hydraulic lifting rod 5, the hydraulic lifting rod 5 is fixed on the supporting platform 6, the supporting platform 6 is located on one side of the aluminum melting furnace 1, the connecting rod 3 is provided with a driving mechanism 8 for controlling the rotation of the edge pressing plate 7, the driving mechanism 8 includes a driven gear 81, a driving gear 82, a driving gear The driving motor 83, the fixed plate 84 and the connecting column 85, the upper end of the fixed plate 84 is fixedly connected to the connecting rod 3 through the connecting column 85, the driving motor 83 is fixed to the lower end of the fixed plate 84, the output shaft of the driving motor 83 is connected to the driving gear 82, the driven gear 81 is sleeved on the outer side surface of the connecting rod 3 and a bearing ring 10 is provided between the driven gear 81 and the connecting rod 3, the driven gear 81 is meshed with the driving gear 82, and the lower end surface of the driven gear 81 is fixedly connected to the edge pressure plate 7 through the inclined rod 9, and the input end of the driving motor 83 and the hydraulic lifting rod 5 is electrically connected to the output end of the external control system.

[0019] The hydraulic lifting rod 5 is lifted and lowered back and forth, thereby controlling the center pressure plate 2 and the edge pressure plate 7 to press the aluminum particles into the aluminum water to accelerate the melting. Since aluminum particles need to be continuously added during the melting process of the aluminum particles, a gap needs to be left between the edge pressure plates 7 to facilitate the feeding. The driving mechanism 8 controls the rotation of the edge pressure plate 7 each time, and the driving motor 83 controls the rotation angle of the edge pressure plate 7 to be 10° each time, so that the aluminum particles outside the coverage area of ​​the center pressure plate 2 are pressed into the aluminum water to ensure the melting efficiency of the aluminum particles.

[0020] Furthermore, in order to reduce the risk of molten aluminum being carried out when the center pressing plate 2 and the edge pressing plate 7 rise and to reduce resistance, the center pressing plate 2 has a conical structure and the upper end surface of the edge pressing plate 7 is an arc surface.

[0021] Furthermore, in order to increase the melting speed of the aluminum particles in the edge area, the number of the edge pressing plates 7 is four, and the four edge pressing plates 7 are evenly distributed on the outer side surface of the central pressing plate 2 .

[0022] Furthermore, in order to ensure that the edge pressing plate 7 and the center pressing plate 2 are pressed into the molten aluminum to the same depth and to facilitate the control of the pressing time, the lower end surfaces of the edge pressing plate 7 and the center pressing plate 2 are flush.

[0023] Furthermore, in order to ensure the pressing area of ​​the edge region, the side of the edge pressing plate 7 close to the aluminum melting furnace 1 is an arc-shaped structure, and the curvature of the arc-shaped structure is adapted to the curvature of the inner side surface of the aluminum melting furnace 1 .

[0024] During use: first set the driving motor 83 to control the rotation angle of the edge pressure plate 7 to 10° each time it is started, and set the time interval for each reciprocating lifting of the hydraulic lifting rod 5. After adding aluminum particles into the molten aluminum, the hydraulic lifting rod 5 contracts, causing the center pressure plate 2 and the edge pressure plate 7 to move downward, pressing the aluminum particles floating in the molten aluminum into the molten aluminum. After the pressing time reaches the set time, the hydraulic lifting rod 5 extends, and the center pressure plate 2 and the edge pressure plate 7 rise. At this time, the driving motor 83 is started, controlling the driving gear 82 and the driven gear 81 to rotate, thereby driving the edge pressure plate 7 to rotate 10°. After adding aluminum particles, the hydraulic lifting rod 5 contracts again, and the above action is repeated.

[0025] The utility model can press the aluminum particles floating in the aluminum melting furnace into the aluminum water by arranging the central pressing plate 2 and the edge pressing plates 7, thereby increasing the melting speed of the aluminum particles in the aluminum melting furnace, shortening the aluminum ingot production time, and improving work efficiency.
