Description

Technical Field

[0001] The utility model belongs to the field of aluminum liquid processing, and specifically relates to an aluminum liquid refining processing unit. Background Art

[0002] After the aluminum ingot is melted into aluminum liquid, hydrogen H2 will be absorbed in the aluminum liquid due to the smelting process, smelting equipment, and water vapor on the surface of the raw materials. The aluminum liquid is usually placed in a transfer bag and then transferred to the refining furnace. The aluminum liquid is refined by a rotary degasser. In the process of transferring the aluminum liquid from the smelting furnace to the refining furnace, forklifts are frequently used for transportation, which increases the labor intensity of the workers. In the process of transportation, the aluminum liquid is prone to sputtering due to the vibration of the vehicle, causing harm to the operators. It is easy to be dangerous when pouring the aluminum liquid. In addition, during the transportation process, the aluminum liquid cools down when it leaves the smelting furnace. In the subsequent processing process, the aluminum liquid needs to be reheated, which increases energy consumption. Transporting aluminum liquid by forklift is not conducive to the realization of automation and intelligence of the workshop.

[0003] Therefore, the above situation needs to be resolved urgently. Utility Model Content

[0004] Purpose of the utility model: In order to overcome the above shortcomings, the utility model provides an aluminum liquid processing device, which eliminates the need to transfer the aluminum liquid between different equipment during the aluminum liquid processing process, and specifically relates to an aluminum liquid refining processing unit.

[0005] Technical solution: In order to achieve the above-mentioned purpose, a molten aluminum refining processing unit includes a melting furnace and a molten aluminum refining pool. The side wall of the melting furnace is connected to the side wall of the molten aluminum refining pool, and the melting furnace and the molten aluminum refining pool are integrated. A culvert is provided at the connection between the melting furnace and the molten aluminum refining pool, and the culvert connects the inside of the melting furnace and the inside of the molten aluminum refining pool. A filter plate is provided inside the molten aluminum refining pool, and the filter plate is perpendicular to the bottom surface of the molten aluminum refining pool. In the utility model, the aluminum block is melted in the melting furnace, and the melted aluminum liquid flows into the aluminum liquid refining pool through the culvert for refining treatment, so as to achieve seamless connection between the melting and refining processes, and there is no need to transfer aluminum liquid between different equipment, which reduces the transfer time and heat loss, improves production efficiency, saves energy costs, reduces smoke and harmful gases generated during the production process, improves the workshop environment, and protects workers from aluminum liquid harm. The melting furnace and the molten aluminum refining pool are integrated to reduce the space occupied by the equipment, simplify the layout of the production line, and facilitate the realization of workshop automation and intelligence. In addition, a filter plate is provided inside the aluminum liquid refining pool to remove impurities in time, ensure the refining effect, and finally obtain aluminum liquid with higher purity, which is beneficial to improve the quality of castings or die-casting products.

[0006] Furthermore, in the above-mentioned aluminum liquid refining treatment unit, the filter plate divides the inner cavity of the aluminum liquid refining pool into a refining chamber and a transmission chamber, and a culvert is set in the refining chamber, and the culvert connects the refining chamber and the melting furnace. The aluminum liquid in the melting furnace enters the refining chamber from the culvert, and the aluminum liquid is fully mixed with the refining agent in the refining chamber. The aluminum liquid passes through the filter plate and enters the transmission chamber. The aluminum liquid is allowed to stand in the transmission chamber to ensure that the reaction is fully carried out. The aluminum liquid enters the transmission chamber through the filter plate, and the filter plate filters the aluminum industry. And during the standing period, the remelting slag in the aluminum liquid further floats to the surface, which is convenient for removal to ensure the cleanliness of the aluminum liquid. Tiny bubbles gather and rise during the standing process, reducing the pores in the casting.

[0007] Furthermore, in the above-mentioned aluminum liquid refining processing unit, the filter plate has a gap, and the gap forms a channel from the refining chamber to the transmission chamber. As the aluminum liquid is continuously filtered through the filter plate, the filter residue may block the filter plate, making the aluminum liquid flow unsmooth or completely blocked. The filtration is subjected to a large pressure, which may cause the filter plate to deform or be damaged. The gap serves as a pressure release channel, which can reduce the pressure on the filter plate, avoid damage to the filter plate, and ensure the safe operation of the equipment.

[0008] Furthermore, in the above-mentioned aluminum liquid refining processing unit, the aluminum liquid refining pool is provided with a left fixing seat and a right fixing seat. The left fixing seat is vertically arranged on the inner wall of the aluminum liquid refining pool, and the right fixing seat is vertically arranged on the inner wall of the aluminum liquid refining pool. The left fixing seat and the right fixing seat are arranged in a straight line. The left fixing seat is provided with a left groove near one end of the right fixing seat, and the right fixing seat is provided with a right groove near one end of the left fixing seat. The two ends of the filter plate slide into one end of the left groove and the right groove respectively, and the left groove and the right groove respectively limit the two ends of the filter plate. The filter plate slides into the left groove and the right groove, ensuring that the filter plate is easy to install and maintain.

[0009] Furthermore, in the above-mentioned aluminum liquid refining processing unit, the refining chamber is a chamber with an opening on the upper side, a refining chamber cover is provided at the upper opening of the refining chamber, and a rotor degasser is provided on the refining chamber cover. The rotor degasser passes through the refining chamber cover and extends into the refining chamber to stir the aluminum liquid for degassing.

[0010] Furthermore, in the above-mentioned aluminum liquid refining processing unit, the transmission chamber is a chamber with an upper opening, a transmission chamber cover is provided at the upper opening of the transmission chamber, the transmission chamber cover is provided with a notch, a heater installation cover is provided at the notch, the heater installation cover is provided with a heater, and the heater extends through the heater installation cover into the transmission chamber to heat the aluminum liquid. The heater heats the aluminum liquid in the transmission chamber, and before the aluminum liquid is supplied to the subsequent process, the aluminum temperature is maintained at a set value, thereby improving production efficiency.

[0011] Furthermore, in the above-mentioned aluminum liquid refining processing unit, in order to improve the degassing efficiency and ensure the degassing effect, the number of rotor degassers is set to 2 or more.

[0012] Furthermore, in the above-mentioned aluminum liquid refining processing unit, in order to improve the heating efficiency and maintain the temperature of the aluminum liquid, two or more heaters are provided.

[0013] Furthermore, in the above-mentioned molten aluminum refining processing unit, in order to avoid the excessive temperature of the filter plate and the residual molten aluminum on the filter plate during the maintenance of the filter plate, causing harm to the staff, connecting studs are provided on the upper side of the filter plate, and the filter plate is fixed to the middle cover plate through the connecting studs. The middle cover plate is arranged on the upper side of the opening of the molten aluminum refining pool, and the middle cover plate is arranged between the refining chamber cover and the transfer chamber cover.

[0014] It can be seen from the above technical scheme that the utility model has the following beneficial effects: in the aluminum liquid refining processing unit of the utility model, the aluminum block is melted in the melting furnace, and the molten aluminum liquid flows into the aluminum liquid refining pool through the culvert for refining treatment, so as to realize the seamless connection of the melting and refining processes, and there is no need to transfer the aluminum liquid between different equipment, which reduces the transportation time and heat loss, improves the production efficiency, saves energy costs, reduces the smoke and harmful gases generated in the production process, improves the workshop environment, and protects workers from aluminum liquid harm. The melting furnace and the aluminum liquid refining pool are set as one, which reduces the space occupied by the equipment, simplifies the layout of the production line, and is conducive to the realization of workshop automation and intelligence. In addition, a filter plate is provided inside the aluminum liquid refining pool to remove impurities in time, ensure the refining effect, and finally obtain aluminum liquid with higher purity, which is conducive to improving the quality of castings or die-casting products.
