Abstract
The utility model relates to a stirrer for producing large-scale foamed aluminum, which comprises a main support frame, a motor, a stirring shaft and stirring blades, wherein the motor, the stirring shaft and the stirring blades are mounted on the main support frame; an upper end bearing seat and a bearing are arranged in the main support frame; and the upper end of the stirring shaft extends out from the upper end bearing seat and is further in transmission connection with the motor. The stirrer is characterized in that the main support frame downwardly extends out to form a lower support frame; a lower end bearing seat and a bearing are arranged under the lower support frame; and the lower end of the stirrer extends out from the lower end bearing seat. The stirrer shaft is supported to rotate via two support points of the upper and the lower end bearing seats with a certain spacing therebetween, so that the rotational stability of the stirring shaft is greatly improved.
Description
Technical field
The utility model relates to a kind of mixing plant that foam melt method is produced large-scale foam metal that is used for, especially for the agitator of producing large-size foamed aluminum.
Background technology
Foamed aluminium is a kind of faster new function of development in recent years-structure-integrated material; the foamed aluminium that wherein has hole-closing structure demonstrates application prospects because of having very high specific strength, specific modulus and good performances such as buffering, damping, thermal insulation and sound absorption at industrial circles such as light structures, surge guard, environmental protection.Its typical case uses and comprises the spacecraft landing buffer, lightweight armor, blast shelter and anti-explosion container, the absorbing sound and lowering noise structure of the vehicles such as bullet train, automobile etc.
The technology of preparation hole-closing structure foamed aluminium mainly contains powder foam method, gas-blowing foaming method and foam melt method at present.The parts that wherein suitable preparation porosity of foam melt method higher (general 〉=85%), billet size are greatly, the pore structure uniformity requirement is lower.Described flux foaming technology is: at first with the aluminium ingot fusing, then aluminum melt is poured in the tackify tube, adding tackifier (being generally calcium metal) also stir, and tackifier at high temperature form refractory oxide and aluminum melt viscosity is increased with the oxygen reaction.After its viscosity reaches appropriate value, add blowing agent and (be generally TiH
2) and quick the stirring so that its quick homogenising in melt is poured into foaming and shaping in the shaping dies then.Blowing agent TiH
2Decomposes discharges a large amount of hydrogen, because melt viscosity is higher, hydrogen is trapped in the aluminum melt and forms foaming structure, just obtains foamed aluminium after solidifying.
In the flux foaming production technology of prior art, the agitator that its stirring operation is used generally is made up of the motor and the blade-carrying shaft that are installed on the main support, stretch out bearing that the shaft upper end cooperates in the middle of main support and the upper shaft bearing thereof, and be in transmission connection with motor, it is simple in structure, uses general.But, in general mixer, its shaft has only a upper end bearing block support to rotate, and the shaft length below the upper shaft bearing is much larger than the part more than the upper shaft bearing, make shaft when rotation less stable, and the aluminum melt that stirs high viscosity, big resistance all needs to select powerful agitator coupling usually, when particularly in the high depth mixing drum, stirring aluminum melt, need bigger shaft rotational power, then require higher the shaft rotational stabilization.
Summary of the invention
The utility model provides a kind of agitator that is used to produce large-size foamed aluminum for solving the problem that above-mentioned general mixer exists, and the shaft rotational stabilization is improved.For this reason, the utility model is by the following technical solutions:
A kind of agitator that is used to produce large-size foamed aluminum, comprise main support, be installed on motor, shaft and stirring vane on the main support, be provided with upper shaft bearing and bearing in the described main support, stretch out from the upper shaft bearing shaft upper end, and be in transmission connection with motor, it is characterized in that: stretch out a lower carriage in the described main support downwards, be provided with bottom end bearing seat and bearing below this lower carriage, stretch out from the bottom end bearing seat shaft lower end.
Further, below the described bottom end bearing seat middle (center) bearing and the ring outside is equipped with adiabatic seat, and perhaps bottom end bearing seat appearance sets firmly an adiabatic overcoat.The bearing degree that is influenced by heat in the bottom end bearing seat is reduced, and functional reliability is better.
Described main support is provided with sulky derrick, and the top of sulky derrick is provided with lifting hole(eyelet), and it can be convenient to external agency and hang and connect lifting;
Described main support two ends are respectively equipped with two rollers and movable clamp up and down.Two rollers can roll with two guide upright posts of outside with movable clamp and be connected and the main support that is fixedly clamped, thereby make agitator work more stable.
Described shaft is connected to form by two sections, and stirring vane is fixed on the hypomere shaft, and it makes shaft processing and installs more convenient.
Useful technique effect of the present utility model is: owing to set up the lower carriage and the bottom end bearing seat of the supporting shaft that stretches out downwards below the main support centre, make shaft by upper shaft bearing and the bottom end bearing seat two point supportings rotation of a determining deviation apart, the shaft rotational stabilization is improved greatly.
