Stokehole aluminum slag treatment equipment and method

Abstract

The invention relates to stokehole aluminum slag treatment equipment and method. The equipment comprises a base, the base is installed on the ground, molten aluminum collecting bases are arranged on the two sides of the base, slag boxes are arranged on the top faces of the molten aluminum collecting bases, liquid outlets are formed in the bottom faces of the slag boxes, rotating assemblies are arranged in the base, the rotating assemblies comprise two limiting bearings, the two limiting bearings are located on the inner bottom face and the inner top face of the base correspondingly, the tail end of a rotating shaft is correspondingly connected with a limiting bearing below, a shaft body of the rotating shaft is correspondingly connected with a rotating motor, the rotating motor is correspondingly connected with the base, the head end of the rotating shaft is in interference fit with the limiting bearing above and is fixedly connected with a rotating base after penetrating through the base, and two lifting assemblies are arranged on the top surface of the rotating base, one of the lifting assemblies is used for driving a composite stirring assembly to ascend and descend, and the other lifting assembly is used for driving a cooling assembly to ascend and descend. The equipment can effectively separate aluminum slag from metal melt, and the equipment further has the advantages ofbeing easy to operate and small in occupied space.

Description

technical field [0001] The invention relates to the technical field of aluminum slag treatment, in particular to a treatment equipment and method for aluminum slag in front of a furnace. Background technique [0002] It is known that a part of aluminum slag will be produced during the smelting process of aluminum, and the aluminum slag is mainly composed of metal and non-metallic impurities, and the heat of the aluminum slag is relatively high, but there is a certain amount of metal melt mixed in the aluminum slag in front of the furnace. These metal melts are dispersed in the aluminum slag in granular form and adhere to the aluminum slag, and the aluminum content of these metal melts is about 40-70% of the aluminum slag amount. If the aluminum slag and the metal melt are not treated A large amount of molten aluminum will be lost, which will increase the cost of aluminum smelting; the traditional aluminum slag processing equipment is ash frying machine. The separation speed...

[0002] It is known that a part of aluminum slag will be produced during the smelting process of aluminum, and the aluminum slag is mainly composed of metal and non-metallic impurities, and the heat of the aluminum slag is relatively high, but there is a certain amount of metal melt mixed in the aluminum slag in front of the furnace. These metal melts are dispersed in the aluminum slag in granular form and adhere to the aluminum slag, and the aluminum content of these metal melts is about 40-70% of the aluminum slag amount. If the aluminum slag and the metal melt are not treated A large amount of molten aluminum will be lost, which will increase the cost of aluminum smelting; the traditional aluminum slag processing equipment is ash frying machine. The separation speed of aluminum slag and metal melt is slow, and the metal melt in high-temperature aluminum slag will continue to be burned, so the metal melt in aluminum slag still has a great loss, which leads to higher cost of aluminum smelting In addition, the ash frying machine occupies a large area and needs corresponding dust removal equipment. The investment cost is high, the operation is more complicated, and special ash frying posts need to be set up, resulting in unbalanced distribution of human resources;

[0003] Chinese patent (CN201910075265.6) discloses an aluminum slag recovery equipment and aluminum slag recovery process. The aluminum slag in the slag pressing box is squeezed by a pressing plate, so that the aluminum in the aluminum slag is hydraulically released and flows into the aluminum liquid collection box. , the aluminum liquid in the aluminum liquid collection box is returned to the melting furnace to continue to be used, and the remaining aluminum slag in the slag press box is transported into the heating furnace for heating through the conveying device, and the heated aluminum slag is put into a centrifuge to separate the aluminum liquid and aluminum slag The separation, the separated aluminum liquid also flows back into the furnace, and the remaining aluminum slag is harmlessly treated at this time. Although the equipment can separate the aluminum liquid in the aluminum slag, the steps are cumbersome, because there are many devices involved , so it needs to occupy a large amount of space and high separation cost; therefore, in summary, the current market needs a method that can effectively separate aluminum slag and metal melt, and is simple to operate and occupies a small space. equipment
