Background technology
The aluminium melt purifying equipment of producing both at home and abroad is made of hopper, feed threeway, pipeline at present, and the effect by gaseous tension is pressed into powder flux in the container in the liquid aluminium liquid by pipeline, to reach the purification purpose.For example: Shandong Aluminum company limited, Xi'an airplane industry company limited, Dongfeng Precision Casting Co., Ltd. of Second Automobile Works etc.The following problem of ubiquity: Purge gas and flux can not evenly be supplied with simultaneously in the working process; Flux easily stops up in pipeline; The flux dosage is unstable and quantitatively inaccurate etc., makes foundry goods not reach expection purifying treatment effect.The existence of these problems has limited the decontamination effect improving of gas and flux greatly, is unfavorable for obtaining high-quality aluminium liquid.
Summary of the invention
The objective of the invention is to overcome above-mentioned the deficiencies in the prior art, provide a kind of flux in pipeline, not stop up, and can quantitatively control the add-on and the uniform purification equipment for liquid aluminium alloy of feed of flux.
The present invention realizes in the following manner:
A kind of purification equipment for liquid aluminium alloy is characterized in that comprising churning rotor, rotor hoisting appliance, flux material feeder, mixing tank, rotary joint; Hopper is equipped with on material feeder top, and hopper top is provided with top pressure closure, and there is a safety valve at the center of top cover; The outlet of material feeder connects mixing tank, and the sidepiece of mixing tank is provided with an inlet mouth, and the outlet of mixing tank was communicated with rotary joint by communicating pipe; Rotation axis has a central through hole, and rotary joint is installed in rotation axis central through hole top; Rotary joint is fixedlyed connected with rotation axis; The churning rotor is fixed on the rotation axis by the rotor-side variable frequency electric machine control, and the churning rotor center is provided with discharge hole; Be connected by a rotor fixer between rotation axis and the rotor.
Above-mentioned purification equipment for liquid aluminium alloy is characterized in that a screw shaft is arranged in the flux material feeder, and the rotation of screw shaft is controlled by the material feeder variable-frequency motor.
Above-mentioned purification equipment for liquid aluminium alloy is characterized in that the churning rotor adopts graphite material to make.
Above-mentioned purification equipment for liquid aluminium alloy, the mixing tank that it is characterized in that material feeder one end is for circular, and there is a blast fence in the internal mixer exit.
Above-mentioned purification equipment for liquid aluminium alloy is characterized in that being equipped with between rotation axis and the rotor rotor fixer that guarantees its coaxial rotation, and the rotor fixer is made of permanent sleeve, locking swivel nut and two semicircular clips.
When the present invention uses, flux enters material feeder by hopper, in material feeder, evenly move into mixing tank, under the effect of gas, rotate, postrotational flux mixes the formation Dual-Phrase Distribution of Gas olid with gas, under the guiding of mixing tank baffle plate, blow out mixing tank, after rotary joint enters rotation axis and centre of rotor hole, spray.The flux of ejection in fact is a kind of mixing refining gas of impossible blocking pipe.
Flux of the present invention control is owing to realize by the variable-frequency motor rotating speed, thereby can be according to the rotating speed difference, and the defeated material amount difference of material feeder in the unit time realizes the quantitative control of flux.Simultaneously, during material feeder work, the magnetic valve in the pneumatic control circuit is opened, and has guaranteed the synchronous output of refining gas and flux.
