Abstract
The utility model discloses a purification device of aluminium alloy melt. The device comprises degassing casings and rotors (3), wherein the degassing casings comprise heating devices, charging ports and discharging ports. The purification device is characterized in that the purification device comprises at least two degassing casings, each degassing casing is connected with each other in series through a communication pipeline (4), the degassing casings are provided with at least two rotors (3), and separating plates (5) are arranged between the rotors (3). The purification device can meet quality requirement of both large-scale production and small-scale production, and is suitable for a relatively wide range of aluminum-water flow by using a parallel degassing device way, thereby enabling an ingot casting specification range applied to a production line to be relatively large and facilitating to save investment cost.
Description
Technical field
The utility model relates to degassing device for molten aluminium, particularly a kind of purifying aluminium alloy melt device.
Background technology
The purification of aluminium alloy melt is the gordian technique that guarantees the aluminum alloy materials Metallurgical Quality, and the hydrogen richness in the reduced rate melt is one of main purpose of aluminium melt purifying.The removing hydrogen from aluminum melt purification techniques can be divided into adsorption cleaning and non-adsorption cleaning two large classes in the eyes by effect, adsorption cleaning is by adding sorbent material (such as gas in molten aluminium, solid purificant etc.), so that in sorbent material and the process that melt contacts, with molten aluminium effect chemistry, physics or machinery occuring, thereby reaches the purpose of dehydrogenation.But not adsorption cleaning is by some physical action (such as vacuum, ultrasonic wave etc.), the equilibrium state of change rate melt-gas, thus reach the purpose that gas is separated from melt.
Utilize the gas refinement agent, be that air blast carries out the adsorption cleaning dehydrogenation to molten aluminium and is, owing to can improve by the dynamic conditions that improves degasification the efficient of dehydrogenation, therefore easy to operate and pollution is lacked, present existing air blast is to grow up 20th century 70, the eighties mostly, according to the introduction method of gas can be divided into that single pipe method, porous blow head are sent out, stationary nozzle method and rotating and puffing argon method.
Find through the literature search to prior art, Wang Changhai etc. are in " casting " 2001, Vol50, No.4, in " in the development of removing hydrogen from aluminum melt technology " literary composition of delivering on the P179-183, existing all kinds of dehydrogenation purifying methods are summed up, and existing degasification method comprises the air blast of flux refining, rotary blowing etc.The state of the art of the dehydrogenation treating plant of various countries can drop to the 0.2-0.4ml/100gAl before processing about 0.1-0.09ml/100gAl mostly at present, and along with the raising of degassing effect, the time that aluminium water needs to stop in the degasifying device again also significantly increases.Present most of producer uses single two rotors degasifying device, and when producing common aluminum alloy in enormous quantities, throughput can't meet the demands.
Summary of the invention
The purpose of this utility model provides a kind of purifying aluminium alloy melt device, when solve producing high-performance aluminium alloy in enormous quantities, can be in batches to the problem of melt degasification.
Scheme of the present utility model is by such realization: construct a kind of purifying aluminium alloy melt device, comprise degasification casing and rotor, described degasification casing comprises heating unit, opening for feed and discharge port, described degasification casing has two at least, connects successively with connecting pipe between each degasification casing; Described degasification casing is provided with at least two rotors, is provided with division board between the rotor in the degasification tank.
Principle of work of the present utility model is, by connecting successively with connecting pipe between the degasification casing, subsequently aluminium water is imported in the degasification casing by chute, aluminium water is through stirring and the heating of rotor, except the purpose of hydrogen, and connecting pipe between the degasification casing is connected successively, and adopt turn more from mode, when can aluminium water passing through each degasification tank, so that hydrogen content reduces gradually, the final purpose that realizes dehydrogenation, this scheme are fit to process aluminium liquid in batches.
In the utility model, as preferred version, described degasification casing is two, namely connects with connecting pipe between degasification tank A and the degasification casing B; Be equipped with two rotors on described degasification tank A and the degasification casing B.
The present invention has following beneficial effect:
1, the utility model both can satisfy the specification of quality of production in enormous quantities, also can satisfy the specification of quality of small serial production; And owing to adopt the mode of degasifying device in parallel, be applicable to wider aluminium discharge, the ingot casting specification limit that a production line is adapted to is larger, is conducive to save cost of investment.
2, the utility model cost of manufacture is low, and is simple in structure, is convenient to promote.
Description of drawings
Fig. 1 is the structural representation of the utility model purifying aluminium alloy melt device.
Component title and sequence number among the figure:
Degasification casing A1, degasification casing B2, rotor 3, connecting pipe 4, division board 5;
Opening for feed A1.1, discharging port A 1.2;
Opening for feed B2.1, discharge port B2.1;
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model purifying aluminium alloy melt device is described.
Embodiment 1:
Such as Fig. 1, this purifying aluminium alloy melt device comprises degasification casing A1 and degasification casing B2, and degasification casing A1 comprises opening for feed A1.1, discharging port A 1.2; Degasification casing B2 comprises opening for feed B2.1, discharge port B2.1; Degasification casing A1 and degasification casing B2 are equipped with two rotors 3 by connecting pipe 4 series connection on degasification casing A1 and the degasification casing B2, are provided with division board 5 between the rotor 3.
During operation, aluminium water is imported degasification casing A1 from opening for feed A1.1, the heating unit in the degasification casing A1 heats, and rotor 3 is by rotating, so that the hydrogen in the aluminium water accelerates volatilization, the effect of degasification casing A1 is preliminary dehydrogenation.Aluminium water flows out from discharging port A 1.2 afterwards, and by connecting pipe 4, opening for feed B2.1 further locates hydrogen work by entering to degasification casing B2, flows out from discharge port B2.1 finally by crossing the aluminium water that purifies.
