In the smelting process, ash and slag are gradually separated from newly melted aluminum water, and the ash and slag float on the surface of the aluminum water.
Step S2, after smelting is completed, a cover of the furnace body 11 is opened, ash is gathered towards one side of the inner wall of the furnace body 11 by rotating the furnace body 11, and the principle is that, referring to FIG. 6, when the furnace body 11 rotates anticlockwise, the inclined furnace body 11 drives contacted aluminum water to move during rotation, so that liquid at the right end of the surface of the aluminum water is brought into depth, liquid at the left end of the aluminum water is brought into the surface of the aluminum water, a phenomenon of rightward flowing is generated at the liquid level of the aluminum water, and ash is gathered towards the right side in the furnace body 11 based on the principle.
Step S3, pushing the trolley 2 to be close to the mouth of the furnace body 11, controlling the electric sliding block 42 to move towards the furnace body 11, controlling the oil cylinder II 23 to stretch and retract, enabling the barrel front section 51 to enter the furnace body 11, enabling the barrel rear section 52 to be located at the mouth of the furnace body 11, enabling the barrel front section 51 to be completely immersed in aluminum water, enabling the axis of the barrel front section 51 to be horizontal, and enabling the slag baffle 53 to protrude out of the surface of the aluminum water.
In step S4, referring to fig. 7, the furnace body 11 is rotated in the opposite direction (clockwise in the present embodiment), so that the slag on the surface of the molten aluminum moves to the other side, and the slag is blocked by the slag blocking plate 53, and the principle of the slag movement is described in step S2, which is not repeated herein.
And S5, controlling the extension of the second oil cylinder 23, and lifting the second oil cylinder to the height of the front section 51 of the cylinder to lift the second oil cylinder away from the surface of the aluminum water, so that ash enters the front section 51 of the cylinder, and the aluminum water in the front section 51 of the cylinder flows out from the front end of the front section 51 of the cylinder and the liquid leakage hole 55.
In the process of moving the front section 51 of the cylinder, the first oil cylinder 44 is controlled to extend slightly, so that the front end of the front section 51 of the cylinder is tilted slightly, and ash is prevented from leaving the collecting cylinder 5 from the front end of the front section 51 of the cylinder. After the front section 51 of the barrel leaves the molten aluminum completely, the ash in the front section 51 of the barrel enters the rear section 52 of the barrel for temporary storage.
And S6, controlling the electric sliding block 42 to move in a direction away from the furnace body 11, so that the collecting cylinder 5 is retracted into the trolley 2, and pushing the trolley 2 away from the furnace body 11.
And S7, placing a container below the front end of the front section 51 of the cylinder, controlling the first oil cylinder 44 to shorten and incline the collecting cylinder 5, enabling the front end of the collecting cylinder 5 to incline downwards, pouring ash in the collecting cylinder 5 into the container from the front end of the front section 51 of the cylinder, and completing slag removal.
In summary, through the equipment and the slag removal process thereof, manual slag removal can be avoided, the problems of severe working environment and potential safety hazard existing in manual slag removal are avoided, and the automatic operation can be realized through the controller, through most actions of the first oil cylinder 44 and the second oil cylinder 23, so that the operation amount of personnel is reduced.
Through this equipment and scarfing cinder technology, just accomplish before pouring out the aluminium water and take off the sediment, compare with the form that current in-process that the aluminium water poured through filtration ash, avoided the ash to spill and get into the mould with the aluminium water in to improve the quality after the aluminium water casting, also avoided a large amount of ash to block up filtration structure's problem, also reduced the condition that the ash is stuck to the inner wall of furnace body 11 and is difficult to the clearance.
The above embodiments are not intended to limit the scope of the application, so that the equivalent changes of the structure, shape and principle of the application are covered by the scope of the application.
