Description

Technical Field

[0001] This application relates to the field of aluminum liquid treatment, and particularly to an aluminum liquid filtering and anti-blocking device. Background Art

[0002] In order to reduce the inclusion content in aluminum and aluminum alloy ingots, it is necessary to filter the aluminum liquid. In the existing production system of aluminum ingots, a filter box for filtering inclusions in the aluminum liquid has been added. The existing aluminum liquid filter box generally includes a matching box body and a box cover. A filter cavity is provided in the box body, and a filter plate for filtering is provided in the filter cavity. The aluminum liquid flows into the filter cavity from one end inlet of the box body, and after being filtered by the filter plate, it flows out of the filter box from the outlet on the opposite side of the box body for further processing in the next process. During the aluminum liquid filtering process, the inclusions filtered by the filter plate are likely to block the filter cavity or the filter plate. At this time, the entire production system needs to be stopped, and the filter cavity and the filter plate need to be dredged. After the dredging is completed, the entire production system of the aluminum ingot is restarted to continue production. Such an operation not only reduces the continuous operation ability, but also causes waste of aluminum liquid and energy loss in the congested section during the closing and restarting processes, increasing the overall production cost.

[0003] To solve the problem of shutdown for maintenance after congestion, the prior art CN107354322A adopts the method of setting a plugging member and an emergency flow channel; specifically, when the inclusions in the aluminum liquid block the filter cavity or the filter plate, the plugging members at both ends of the emergency flow channel are removed, and the filter cavity is blocked at the connection with the first inlet and the first outlet of the filtering device by using the plugging members. The aluminum liquid flowing in from the first inlet can no longer flow into the filter cavity, but flows into the emergency flow channel and flows out of the box body from the first outlet for further processing. When the aluminum liquid flows through the emergency flow channel, the aluminum liquid flowing through the box body flows out of the box body without being filtered for further processing. The maintenance personnel can clean the blockage in the filter cavity or replace the filter plate. After completion, the plugging members at both ends of the filter cavity are removed, and the two ends of the emergency flow channel are plugged again. The aluminum liquid entering the box body flows through the filter cavity again and is filtered by the filter plate, and the aluminum liquid filter box is in a normal filtering state.

[0004] Although this solution improves the continuous operation ability, since the aluminum liquid flowing through the emergency flow channel is not filtered, and it often takes a long time to repair the filter cavity. During this period, a large amount of aluminum liquid flows out through the emergency flow channel, resulting in a large number of aluminum ingots having quality problems. And if the repair time is too long, it is necessary to stop the machine to avoid more problems with aluminum ingots, which means that the continuous operation ability has not been improved; and during the period from the congestion of the filter cavity to the closing of the filter cavity, it will still cause waste of aluminum liquid and energy loss in the congested section. Summary of the Invention

[0005] To solve the problems existing in the prior art, the present application discloses an aluminum liquid filtering and anti-blocking device. The aluminum liquid filtering and anti-blocking device includes a housing, an aluminum liquid inlet channel, an aluminum liquid outlet channel, a filtering component, and a vibration component. The housing includes adjacent and perpendicular first and second side walls. The aluminum liquid inlet channel passes through the first side wall, and the aluminum liquid outlet channel passes through the second side wall. The filtering component connects the aluminum liquid inlet channel and the aluminum liquid outlet channel;

[0006] Wherein, the filtering component includes a filter screen. The aluminum liquid entering from the aluminum liquid inlet channel flows through the filter screen and then enters the aluminum liquid outlet channel. The vibration component can impact the filter screen.

[0007] The filtering component includes a filtering rotating shaft, and the filtering rotating shaft can drive the filter screen to rotate.

[0008] The filtering component is located above the aluminum liquid outlet channel, and the vibration component is located above the filtering component.

[0009] The vibration component includes a vibration sphere, a collision precursor, a collision support body, a collision track, a collision connecting rod, a cylinder, and a piston. The collision track and the cylinder are arranged inside the vibration sphere. The piston is arranged inside the cylinder. The piston and the side wall of the cylinder enclose an in-cylinder sealed space, and an inert gas is preset in the in-cylinder sealed space. The connecting rod connects the piston and the collision support body. One end of the collision support body is connected to the connecting rod, and the other end of the collision support body is connected to the collision precursor. The collision support body can drive the collision precursor to move in the collision track. When the collision support body moves in the collision track, the collision support body drives the piston to move in the cylinder through the connecting rod, thereby changing the volume of the inert gas in the in-cylinder sealed space.

[0010] The vibration component further includes a vibration rotating shaft. The vibration sphere includes a vibration rotation center. The vibration rotating shaft drives the vibration sphere to rotate through the vibration rotation center. The vibration rotation center and the collision track are respectively arranged on both sides of the cylinder. The cross section of the vibration sphere is spherical, and the vibration rotation center does not coincide with the center of the vibration sphere. During the rotation of the vibration sphere driven by the vibration rotating shaft, with the vibration rotation center as the center, the movement track of the collision precursor forms a vibration rotation track, and the vibration rotation track is circular.

[0011] Both the collision track and the collision support body are conical structures.

[0012] The outer shell of the oscillating sphere at the outer end of the collision orbit is the collision position shell. The circle where the outer shell of the oscillating sphere is located is the virtual collision position shell outside the collision orbit. A collision avoidance space is formed between the virtual collision position shell and the collision position shell.

[0013] The aluminum liquid filtering and anti-blocking device further includes a first motor (not shown in the figure), a second motor (not shown in the figure), a first pole column, and a second pole column. The first motor and the second motor are located inside the shell. The first motor is connected to the filtering rotating shaft and can drive the filtering rotating shaft to rotate. The second motor is connected to the oscillating rotating shaft and can drive the oscillating rotating shaft to rotate. The rotation speeds of the first motor and the second motor can be adjusted according to the change of the aluminum liquid flow rate. The first pole column and the second pole column are connected to an external power supply. The first motor is electrically connected to the first pole column and the second pole column. The second motor is electrically connected to the first pole column and the second pole column.

[0014] The filtering assembly further includes a filtering front wall, a filtering rear wall, and a filtering bottom wall. The filter screen is located between the filtering front wall and the filtering rear wall, and the filter screen is connected to the filtering front wall and the filtering rear wall. One side of the filtering front wall is connected to the side wall of the outlet channel of the aluminum liquid outlet channel, and the other side of the filtering front wall is connected to the filter screen. The filtering rear wall is connected to the filter screen and the filtering bottom wall. The filtering bottom wall is connected to the filtering rotating shaft. The filtering rotating shaft can drive the filtering bottom wall, and then drive the filter screen, the filtering front wall, and the side wall of the inlet channel to rotate.

[0015] Wherein, in the vertical direction, the cross-sectional area of the filter screen is larger than the cross-sectional area of the aluminum liquid inlet channel.

[0016] The aluminum liquid filtering and anti-blocking device further includes a filtering lower shell, a filtering upper shell, and an oscillating outer shell located inside the shell. The filter screen, the filtering front wall, the filtering rear wall, and the filtering bottom wall are located in the space surrounded by the filtering lower shell and the filtering upper shell. The lower end of the filtering lower shell is open, and the lower end of the filtering lower shell is connected to the side wall of the outlet channel of the aluminum liquid outlet channel. The filtering rotating shaft passes through the filtering lower shell. The oscillating sphere is located in the space surrounded by the oscillating outer shell. The oscillating rotation trajectory is located in the space surrounded by the oscillating outer shell. The cross-sectional area of the aluminum liquid outlet channel is larger than the cross-sectional area of the aluminum liquid inlet channel.

[0017] The method disclosed in this application has the following advantages:

[0018] By means of oscillating and rotating the filter screen, the enrichment of impurities in the molten aluminum on the filter screen is reduced, the occurrence time of congestion is alleviated, and the continuous operation ability is improved. Moreover, since the cross-section of the filter cavity in the vertical direction is larger than that of the molten aluminum inlet channel in the vertical direction, while the filter cavity has extra space to buffer the molten aluminum, the impurity retention capacity in the filter cavity is also improved, further enhancing the continuous operation ability. In addition, the cross-sectional area of the molten aluminum outlet channel is larger than that of the molten aluminum inlet channel, which also further improves the continuous operation ability.

[0019] The intermittent oscillation mode and the continuous oscillation mode can be selected according to the flow rate of the molten aluminum; and by adjusting the rotational speed difference between the filter component and the oscillation component, different accelerations can be generated on the filter screen by the collision precursor, so as to adjust the magnitude of the oscillation force.

[0020] The conical design of the collision support body and the side wall of the collision track limits the downward movement of the collision support body, preventing the collision precursor from breaking through the filter screen and causing safety problems.

[0021] During the expansion process of the collision precursor and the filter screen, since the filter screen and the oscillation component are rotating, in addition to generating an upward force on the collision precursor, a horizontal force will also be generated on the collision precursor. The setting of the collision avoidance space in the oscillation component weakens the impact on the oscillation ball housing caused by the horizontal force on the collision precursor and the collision support body during the expansion process of the collision precursor and the filter screen, and improves the service life of the oscillation component.
