Description
Technical field
The utility model relates to a kind of accessories of metal smelt system, and in particular to one kind goes out for aluminium alloy smelting smelting furnace
The chute device efficiently to remove the gred is realized when liquid.
Background technique
During aluminium alloy smelting, on the one hand due to the activity of material, molten aluminum is easily oxidized, another aspect aluminium ingot
Usual supplied materials is impure, so as to cause a large amount of slag inclusion is contained in molten aluminum.Before being cast, need to separate aluminium slag therein
And remove, it otherwise will greatly influence casting character.
Common practice is directly to flow into molten aluminum in crucible by discharge port, is transferred to degasification station and carries out degasification slagging-off.It removes
Slag device usually passes through addition deslagging agent, is stirred, and separates molten aluminum and impurity, impurity swims in above molten aluminum and gone
It removes.For example, Chinese invention patent application CN105057653A discloses a kind of molten aluminum slag device, including rack, motor, stirring
The hopper of lifter and energy self-emptying that bar, controller, control motor are gone up and down, the hopper and lifter are arranged in rack
On, one end of the stirring rod is fixed on the output shaft of motor, and forms the angle greater than 0 ° with the output shaft of motor, described
Lifter, motor, hopper are electrically connected with controller.Hopper equipped with slagging agent is automatically added to slagging agent into molten aluminum, meanwhile, it rises
Drop device control motor moves down, and makes to stir in bar part immersion molten aluminum, motor drives stirring rod rotation, makes slagging agent and molten aluminum
It is uniformly mixed.
But this method has the disadvantage that
1, aluminium alloy liquid is directly entered crucible by discharge port, then send to degasification station, and in the process, a large amount of surface is floating
Slag can be involved in molten aluminum again, since aluminium slag and molten aluminum density are close, are difficult quick separating, are increased the difficulty of subsequent slagging-off
Degree, reduces the quality of molten aluminum.
2, after deslagging agent is added, generally requiring to carry out preheating in 1 minute or so just can be carried out chemical reaction, reduce production
Efficiency.
3, if deslagging agent is directly sprinkling upon crucible surface, the heated easily agglomeration of deslagging agent is unable to fully contact with molten aluminum, make
At the waste of deslagging agent.
Therefore, it is necessary to improve to existing slagging-off mode, surface scum is separated in molten aluminum discharging, on solving
State problem.
Summary of the invention
The goal of the invention of the utility model is to provide a kind of device for aluminium alloy slagging-off, realizes removing in discharging
Slag.
To achieve the above object of the invention, the technical solution adopted in the utility model is: a kind of dress for aluminium alloy slagging-off
It sets, including chute, deslagging agent charging hopper, dreg collecting slot, the upstream of the chute is molten aluminum import, in the downstream of the chute
Filtering ponds are connected with, filter is equipped in filtering ponds, are discharge hole, the outlet pair of the deslagging agent charging hopper below filter
The upstream end of the quasi- chute.
In use, the discharge port of aluminium alloy smelting furnace is opened, while slagging-off is added into chute from deslagging agent charging hopper
Agent, deslagging agent will be mixed equably with molten aluminum at this time.Mixing liquid flows into filtering ponds, flows into below discharge hole by filter
In crucible.After blowing, it will filter out the slag come and scoop in dreg collecting slot, the cleaning of filtering ponds is kept, to continue next time to put
Material.
Further technical solution, the deslagging agent charging hopper are equipped with control valve.It can be with by the on-off of control valve
Guarantee the in due course addition of deslagging agent.
Further technical solution, the chute upstream are equipped with the connecting flange for connecting aluminium alloy discharge outlet of furnace.
In above-mentioned technical proposal, the dreg collecting slot is located at the side of filtering ponds.
Preferably, the filtering hole area of the filter is 0.5~1.2cm2。
Preferably, the diameter of the filtering ponds is greater than 2 times of chute width, and it is deep that the depth of the filtering ponds is greater than chute
Degree.
Preferably, the volume of the filtering ponds is greater than the volume of the chute.
Due to the application of the above technical scheme, the utility model has the advantage that compared with prior art
1, deslagging device is arranged between discharge port and crucible the utility model, just removes the gred, avoids in discharging
Aluminium slag is involved in the possibility of molten aluminum again, improves slagging-off efficiency.
2, deslagging agent charging hopper is arranged in the upstream of chute in the utility model, thus to deslagging agent during discharging
Sufficient preheating has been carried out, the subsequent time for needing to preheat is omitted.
3, deslagging agent is changed to adjustable funnel by the mode that hand is spread by the utility model, can be by deslagging agent and molten aluminum
The phenomenon that uniformly mixing, avoiding agglomeration, saves the dosage of deslagging agent.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model embodiment；
Fig. 2 is the top view of Fig. 1；
Fig. 3 is the stereoscopic schematic diagram of embodiment.
Wherein: 1, deslagging agent charging hopper；2, chute；3, filtering ponds；4, filter；5, dreg collecting slot；6, control valve.
Specific embodiment
The utility model is further described with reference to the accompanying drawings and embodiments:
Embodiment one: referring to shown in Fig. 1 to Fig. 3, a kind of device for aluminium alloy slagging-off, including chute 2, deslagging agent add
Funnel 1, dreg collecting slot 5, the upstream of chute 2 are molten aluminum import, can pass through the discharging of setting connecting flange and aluminium alloy smelting furnace
