Embodiment 1

[0022] Such as figure 1 As shown, a kind of aluminum slag recovery equipment includes primary recovery equipment, secondary recovery equipment and slag ash processing equipment, the primary recovery equipment includes a slag pressing box 1, and the upper part of the slag pressing box 1 is provided with a movable up and down Pressing plate 2, above the pressing plate is provided with a pressure head 3 that can move up and down, the pressing head 3 is connected with the hydraulic press 4, and the pressing head 3 can apply pressure to the pressing plate 2 downward under the action of the hydraulic press 4. The lower bottom surface of the slag box 1 is provided with a through hole for liquid aluminum to pass through, and a liquid aluminum collection box 5 is provided below the slag box 1; the secondary recovery equipment includes a heating furnace 6, and the inside of the slag box 1 is The aluminum slag is transported into the feed inlet of the heating furnace 6 through the convey...

Embodiment 2

[0027] A kind of aluminum slag recovery process, utilizes described aluminum slag recovery equipment, comprises the following steps:

[0028] (1) One-time recovery: put the aluminum slag taken out from the furnace into the slag pressing box 1, and then start the hydraulic press 4, so that the pressure head 3 presses down on the pressing plate 2 under the action of the hydraulic press 4 to squeeze the aluminum slag. The aluminum liquid in the aluminum slag flows into the aluminum liquid collection box 5 through the through hole on the lower bottom surface, and then flows back into the melting furnace for further utilization;

[0029] (2) Secondary recovery: take out the remaining aluminum slag from step 1 from the slag pressing box 1, and then transport it into the heating furnace 6 through the conveying device to heat it to 700°C, keep it warm for 60 minutes, and then transfer it to the centrifuge for separation , the separated molten aluminum is returned to the furnace for fu...

Embodiment 3

[0033] A kind of aluminum slag recovery process, utilizes described aluminum slag recovery equipment, comprises the following steps:

[0034] (1) One-time recovery: put the aluminum slag taken out from the furnace into the slag pressing box 1, and then start the hydraulic press 4, so that the pressure head 3 presses down on the pressing plate 2 under the action of the hydraulic press 4 to squeeze the aluminum slag. The aluminum liquid in the aluminum slag flows into the aluminum liquid collection box 5 through the through hole on the lower bottom surface, and then flows back into the melting furnace for further utilization;

[0035] (2) Secondary recovery: take out the remaining aluminum slag in step 1 from the slag pressing box 1, and then transport it into the heating furnace 6 through the conveying device for heating to 850°C, keep it warm for 30 minutes, and then transfer it to the centrifuge for separation , the separated molten aluminum is returned to the furnace for fur...

Abstract

The invention belongs to the technical field of aluminum slag recovery, and particularly relates to an aluminum slag recovery equipment and process. The aluminum slag recovery equipment can realize two-step recovery of aluminum slag by extrusion treatment and heating centrifugal separation treatment, so that the aluminum slag can be recovered more thoroughly, and the harmless treatment of slag ashcan be realized to prevent the slag ash from harming the environment. According to the aluminum slag recovery process, aluminum in the aluminum slag is completely recovered by two times of the recovery process, and the recovery rate is as high as 93%, so that huge economic benefits are produced, and aluminum resources are greatly saved; no salt fluxing agent is applied, so that the pollution to the environment is reduced; and the slag ash is finally subjected to harmless treatment, harmful substances in the slag ash can be greatly reduced, and the pollution to the environment of the slag ashis reduced.

Description

technical field [0001] The invention belongs to the technical field of aluminum slag recovery, and in particular relates to aluminum slag recovery equipment and an aluminum slag recovery process. Background technique [0002] The demand for metal aluminum and aluminum alloys in modern society is increasing. Aluminum and aluminum alloys are widely used in construction, aviation, power transmission, automobile manufacturing, household appliances and other fields. With the rapid development of aluminum alloy deep processing enterprises, aluminum Alloy processing enterprises produce a large amount of waste aluminum slag in the process of aluminum alloy smelting. Aluminum slag is an important secondary aluminum resource, and the content of metal aluminum reaches 20% to 60%. These waste aluminum slags are usually treated as industrial waste by enterprises, which not only pollutes the environment but also causes a great waste of resources. Even if some enterprises recycle waste al...
