Description
Technical field
The present invention relates to smelting non-ferrous metal and casting field.The device is mainly used for carrying out refining to aluminium alloy melt removing
Gas, particularly applies to the on-line continuous refining degasification of aluminium alloy.
Technical background
Because solubility of the hydrogen in high temperature aluminium alloys liquid is larger, and when solidification, its solubility drastically diminishes, and works as aluminium
The hydrogen dissolved in alloy liquid is excessive, if do not done degassing processing, in aluminum melt process of setting, has a large amount of hydrogen and separates out, casting
A large amount of stomatas are formed in part, cause cast properties not meet the requirements.So aluminium alloy in fusion process, it is necessary to carry out degasification
Processing, presently commercially available refining depassing unit, structure are commonly gear reducer driving belt pulley to drive transmission shaft to rotate, transmission shaft
Top is provided with swivel joint, and transmission shaft bottom is provided with refining rotor and impeller, gear reducer driving belt pulley and essence during work
Rotor and wheel rotation are refined, and refinery gas is passed through to swivel joint, refinery gas is through transmission shaft, refining rotor and impeller center
Hole, is drained into molten aluminum, and the bubble of dispersivity is broken into through high-speed rotation impeller, under the action of gas diffusion pressure, melt
In hydrogen be constantly diffused into refinery gas bubble, and constantly float take aluminium alloy melt out of so that by aluminium alloy melt
Hydrogen remove.
Above-mentioned conventional apparatus can preferably realize the refining degasification of aluminium alloy melt, and conventional apparatus is in use, special
It is not that there is also some problems when being used for on-line continuous refining degasification.First, refining is driven using gear reducer driving belt pulley
Rotor rotates, and gear reducer, belt pulley and transmission shaft are installed on platform, and occupied space is larger, some spaces are compared by
For the aluminium alloy smelting equipment of limit, often since space limits, this refining depassing unit can not be installed, i.e., enabled peace reluctantly
Dress, can also influence the use operation of miscellaneous equipment；Again, fluctuation is produced in refinery gas bleed pressure and flow and molten aluminum liquid level
When, easily there is the venthole that aluminium alloy melt enters refining rotor center, and solidification or slagging block venthole, cause to refine
Gas cannot be introduced into aluminium alloy melt, and cause concise rotor and impeller idle running, and not have gas discharge, can not play refining and remove
Gas act on, as operator for a long time do not realize in time, often lead to batches of castings and scrap.
The content of the invention
The object of the present invention is to be directed to, traditional alloy refining depassing unit space is larger and refining rotor is easy to stifled
The present situation of plug, develops a kind of small volume, the refining depassing unit that refining rotor is not easy to plug, and the present invention changes traditional gear reducer
Driving belt pulley refines the structure of rotor rotation, swivel joint of the creative use to the formula of wearing to drive so that machine shaft,
Transmission shaft, swivel joint, refining rotor and impeller central shaft point-blank, it is required to greatly reduce the depassing unit
Installation space.Meanwhile filler of breathing freely made of not viscous aluminum is packed at refining rotor bottom and impeller center, and
The bottom plug with venthole is installed by wheel bottom to be packaged filler, is conveyed into easy to refinery gas in aluminium alloy melt
While, it is therefore prevented that aluminium alloy melt blocks caused by flowing back into refining rotor vent holes.
Realizing the concrete technical scheme of the present invention is：
A kind of alloy refining depassing unit, including motor（1）, shaft coupling（2）, bearing（3）, bearing block（6）, rotation connect
Head（4）, swivel joint air inlet（11）, transmission shaft（5）, refining rotor（7）, impeller（8）, ventilative bottom plug（9）With ventilative filling
Thing（10）, bearing block（6）There is a flange in upper end, for installing motor（1）, bearing block（6）Lower end flanges are used to set with being refined
It is standby to be connected, transmission shaft（5）Upper end passes through swivel joint（4）Afterwards with motor（1）Pass through shaft joint（2）Connection, transmission shaft (5) lower end
Be connected with refining rotor (7), refine rotor (7) and be connected with impeller (8), impeller (8) lower end cannot not insert viscously aluminium and breathe freely filler
(10) after, encapsulated with the ventilative bottom plug (9) for being provided with venthole, transmission shaft (5) is provided with venthole with refining rotor (7) center.
