Description

A kind of molten aluminum transmission variable-pitch auger axis
Technical field
The present invention relates to the screw conveyors of molten aluminum, in particular to be molten aluminum transmission helical axis.
Background technique
Currently, the transport of molten aluminum is transported using transfer ladle, which is to lead the aluminum water in smelting furnace Enter transfer ladle, transfer ladle is transported by fork truck, and aluminum water is then poured into final mold, makes product, process companion With scattering and disappearing for temperature of aluminum liquid, molten aluminum fortune during pollution by impurity unknown in air, personnel in transportational process set The disadvantages of standby generated expense.
It omits transfer ladle and generallys use horizontal screw conveyor transmission mode, main component is helical axis, works as starting When machine helical axis rotates, material is acted on by the normal thrust of helical blade, is acted in the axial thrust load of blade normal thrust Under along material one slot axial movement, to realize the conveying of material.Helical axis majority is using cold rolling steel currently on the market Matter, the material are out of question for the transport of common material, but can not only pollute aluminum water purity for the transport of high-purity molten aluminum, but also It is easy to deform at high temperature, service life is short.Due to ceramic material poor toughness, so process is difficult, for spiral shell Complex component as spin axis is easy to be broken in process, but also to guarantee the angle and screw pitch of helical blade. So there are no the helical axis of ceramics currently on the market.The use that our ceramic material can not only meet transport molten aluminum is wanted It asks, but also molten aluminum purity will not be polluted, therefore assault fortified position and develop, rafifinal hydraulic power helical axis has important meaning Justice.
Summary of the invention
Molten aluminum purity is influenced in order to solve the problem of to be contaminated in molten aluminum transport, the invention proposes a kind of aluminium Liquid transmits variable-pitch auger axis.The helical axis makes by using silicon nitride ceramics composite material and forms, the helical-blade of varying pitch Molten aluminum is transported to the other end from one end of conveyer with lower revolving speed by piece, and the ceramic hardness after being sintered is high, not viscous melting Molten aluminum, it is pollution-free to molten aluminum transport, solve the technical issues of influencing purity in molten aluminum transport.
The solution adopted by the present invention to solve the technical problem is that:
Variable-pitch auger axis includes helical axis 1, helical blade 2;Geometry element are as follows: helical blade diameter phi D, helical axis are straight Diameter φ d, helical blade front end pitch P I, helical blade rear end pitch P II and helical blade thickness S, helix angle β, helical-blade Helix angle α at piece inner edge;
φ D=the 130mm, φ d=40mm, P I=200mm, P II=300mm, S=20mm, α=87 °, β=100 °;
The helical axis uses silicon nitride ceramics composite material;
The processing that screw thread is carried out after the helical axis production forming and sintering, in such a way that lathe and milling cutter combine, workpiece Rotary shaft three-shaft linkage, change gear screw pitch 192mm, spindle Turning degree 7.5r/min, every step feed velocity want slow-motion Cheng Yao little, often 90min will carry out tool changing, and to ensure that accuracy reserves 0.2mm, each 0.05mm, angular thread change gear screw pitch is 2mm, in ten times Carry out turning.
Good effect does not glue molten aluminum liquid, to molten aluminum since the present invention is using the production molding of silicon nitride ceramics composite material It transports pollution-free;It is machined out again after sintering, helical blade uses varying pitch structure, and helical blade front end screw pitch is less than spiral The slide surface of blade rear end screw pitch, molten aluminum changes and impurity in molten aluminum is discharged, and accelerates the transmission of molten aluminum.It is suitable for as aluminium Liquid transmits helical axis application.
Detailed description of the invention
Fig. 1 is structure of the invention sectional view.
In figure, 1. helical axis, 2. helical blades, φ D. helical blade diameter, φ d. spiral shaft diameter, I, helical blade of P Front end screw pitch, II, helical blade rear end screw pitch of P, S. helical blade thickness, β helix angle, spiral at α helical blade inner edge Lift angle.
Specific embodiment
According to the figure, variable-pitch auger axis includes helical axis 1, helical blade 2;Geometry element are as follows: helical blade is straight Diameter φ D, helical axis diameter phi d, helical blade front end pitch P I, helical blade rear end pitch P II and helical blade thickness S, spiral shell Revolve lift angle β, helix angle α at helical blade inner edge;
φ D=the 130mm, φ d=40mm, P I=200mm, P II=300mm, S=20mm, α=87 °, β=100 °.
The helical axis uses silicon nitride ceramics composite material.
The processing that screw thread is carried out after the helical axis production forming and sintering, in such a way that lathe and milling cutter combine, Workpiece rotary shaft three-shaft linkage, change gear screw pitch 192mm, spindle Turning degree 7.5r/min, every step feed velocity want slow-motion journey to want Small, every 90min will carry out tool changing, and to ensure that accuracy reserves 0.2mm, each 0.05mm, angular thread change gear screw pitch is 2mm, Turning is carried out in ten times.
The working principle of the invention:
High-purity molten aluminum is very high to apparatus requirement, and easily pollutes in transportational process, omits transfer ladle screw shaft structure and connects Resume it is defeated, can be realized high-purity molten aluminum conveying, handling, can also according to actual needs, during transportation complete mixing, stir It the technological operations such as mixes, heat, and realizing the conveying of high-temperature material.Screw shaft structure is simply durable, small in size and compact, completely It is sealing, it is ensured that dust-proof and Seal Design, molten aluminum heat are not lost, and realize closed conveying, reduce dirt of the environment to molten aluminum Dye.
Helical blade nominal diameter φ D is an important parameter of horizontal screw conveyor, the production with screw conveyor Amount and structure size are directly related.If calculating helical blade nominal diameter in advance according to formula in the case where known quality conveying capacity Q Then φ D can be checked again after determining other parameters.
The size of screw pitch S decides that the size of helix angle β, the size of helix angle directly affect aluminium block in transmission process Component size directly affects the transport status of aluminium in transmission process.Moreover, after conveying capacity and helical blade diameter determine, Screw pitch changes, and fill factor also changes therewith, and the slide surface of material also changes therewith, directly affects horizontal spiral shell Revolve the transmission process of conveyer.The I back segment pitch P II of helical axis leading portion pitch P, mainly being considered using this form will be in molten aluminum Impurity excludes, and accelerates the discharge capacity of aluminum water.
Helical axis journal diameter φ d and screw pitch have codetermined the size of helix angle α at helical blade inner edge, axle journal Size is related with screw pitch, while its size also determines the glide direction and VELOCITY DISTRIBUTION situation of material, so, it to determine rationally Journal diameter φ d and pitch P relationship.The determination of reasonable axle journal and screw pitch relationship will be from the aspect of following two: (1) The friction law of helicoid and aluminium material;(2) the appropriate distribution of velocity component.
Advantages of the present invention:
The material of helical axis uses silicon nitride ceramics composite material, pollution-free to high-purity molten aluminum, but also high temperature resistant, not viscous melting Molten aluminum, so during transportation, solving the problems, such as that high-purity molten aluminum is easy pollution.
