Abstract

The utility model provides an aluminum alloy deaerator of a suspending type rotating and blowing rotor, which comprising a noble gas bottle, a control cabinet, a blowing hose and a blowing rotor. The utility model is characterized in that the aluminum alloy deaerator is also provided with a circular thermal insulation cover with a central hole, wherein, a supporting frame and a hanging ring are arranged on the thermal insulation cover, a hollow rotating shaft is vertically arranged at the center of the thermal insulation cover by a bearing arranged on the supporting frame, and the blowing rotor is connected with the hollow rotating shaft by screw threads through the central hole of the thermal insulation cover. The motor is arranged on the supporting frame, the hollow rotating shaft is driven to rotate by a pulley speed reducer, and the top of the hollow rotating shaft is connected with the blowing hose by a universal joint. The deaerator has the advantages of simple structure, low cost, good thermal insulation, convenient operation, etc.

Description

Suspension type rotation air blowing rotor aluminium alloy getter

The utility model belongs to the Metal Melting degasifying device, particularly a kind of suspension type rotation air blowing rotor aluminium alloy getter, and degasification is used when being suitable for aluminium alloy smelting.

Aluminium alloy is easy to absorb airborne hydrogen when high temperature fused state, make foundry goods produce needle pore defect, therefore must be with this this gas clean-up in the smelting aluminium alloy process.More effective way is to utilize blow head fast rotational in liquid aluminium alloy in prior art, to be blown into rare gas element in the alloy (as nitrogen by blow head, argon gas) is broken into tiny bubble, makes it slowly come-up and combine with obnoxious flavour (hydrogen) and harmful inclusion and reach degassing purpose.Currently used getter is as a radial drilling machine movably, its housing, rare gas element bottle and column are arranged on the vehicle frame, cantilever is connected with machine art guide rail with guide groove, can move up and down by lifting device, the rotation blow head is loaded on the cantilever front end, and with the driven by motor rotation, its ventpipe is connected with the rare gas element bottle by housing.This getter weak point is a complex structure, and volume is big, the cost height, and inconvenient operation, it is very fast to lower the temperature during processing etc., is not suitable for little factory and uses.

The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of simple in structure, low cost of manufacture, good heat insulation and suspension type rotation air blowing rotor aluminium alloy getter easy to use.

Task of the present utility model realizes by this way; This getter includes the rare gas element bottle, housing, air blowing flexible pipe and air blowing rotor, its feature also has a circular insulation cover that has centre hole, on insulation cover, be provided with support and suspension ring, hollow axle is by being arranged at the perpendicular insulation cover center that places of bearing on the support, the air blowing rotor links together with screw thread and hollow axle by the centre hole of insulation cover, motor is arranged on the support, drive hollow axle by pulley deceleration device and rotate, the hollow axle top is hose connection with air blowing by a universal joint.

The utility model is work like this; The crane that utilizes the workshop during use hangs the insulation cover of getter in body of heater reposefully or waters and wrap, starter motor and open the rare gas element bottle then, electric motor just props up the hollow axle rotation by the pulley deceleration device band, order about the air blowing rotor rotation, meanwhile, rare gas element just passes through the air blowing flexible pipe, hollow axle and air blowing rotor blow out toward the aluminium alloy that dissolves, at the bottom of the air blowing rotor rotation is broken into small bubbles and is uniformly distributed in furnace bottom or casting ladle, slowly rise, thereby realize the degasification requirement.

Compared with the prior art the utility model has following advantage: simple in structure, to make easily, and cost is low; Owing to be provided with insulation cover, in the degassing processing process, can reduce the decline of temperature of aluminum liquid; Easy to operate, flexibly.Therefore, this getter is suitable for middle-size and small-size aluminium alloy casting factory most and uses.

Below in conjunction with accompanying drawing concrete structure of the present utility model is further described.

Fig. 1 is the synoptic diagram of the utility model concrete structure.

Fig. 2 is the local amplification view of rotatable parts among Fig. 1.

With reference to Fig. 2, the insulation cover 3 that has centre hole 15 is that the case 13 that is welded into by steel plate and the refractory brick thermal insulation layer 14 of interior block constitute.Support 8 and suspension ring 9 are welded on the case of insulation cover 3.Hollow axle 4 is by being arranged at the upper and lower bearing 16 perpendicular centers that place insulation cover 3 on the support 8.Motor 5 is arranged on the support 8, and its output shaft is connected with hollow axle 4 by pulley deceleration device 6.Air blowing rotor 2 by centre hole to be threadedly connected on the hollow axle 4.The top of hollow axle 4 is connected with air blowing flexible pipe 10 by a universal joint 7.Air blowing flexible pipe 10 the other ends are by switch and the under meter and 12 bindings of rare gas element bottle of housing 11.The keying of motor 5 is also by housing 11 controls.Suck hydrogen once again and reduce the detrimentally affect of flowing the furnace wall is produced fast in order to eliminate vortex that aluminium liquid produces when the degasification, a refractory baffle 1 made from aluminum silicate fiber that is connected with insulation cover 3 is set in that air blowing rotor 2 is other because of aluminium liquid.The air blowing rotor is made with graphite, from the distance of furnace bottom with 8-12 centimetre for well.
