Description
Technical field
The utility model relates to a kind of fixedly device of material that sieves, and more particularly, relates to a kind of fixedly device of material of screw mechanism screening that uses.
Background technology
Often need to use the screen cloth screening through solid materials such as the coal cinder of crusher in crushing, ores.The similar WARP-KNITTING of structure of tradition screen cloth, divide plain weave mesh screen and ripple mesh screen, this class screen cloth is easy deformation or breakage under the bump of solid material, extruding not only, but also mesh and the big problem of scarfing cinder difficulty take place to stop up easily, especially the solid material of water was sprayed in screening, the sticking stifled problem of easier generation.In order to solve the problem that prior art exists, people have invented a variety of spiral screens.As, " spiral screen " that China Patent No. 200620077880.3 proposes.Though the technical scheme of this invention has been used screw drive mechanism, " frame is installed a unit along the stepped setting of the direction of motion of material on each grade ladder ".But " ladder " modular construction more complicated in this patented technology scheme is unfavorable for reducing breakdown rate.
Summary of the invention
At the deficiencies in the prior art, the purpose of this utility model provides a kind of screw rod sieve, and its structure is simpler, helps reducing the fault rate and the manufacturing cost of screw rod sieve.
The purpose of this utility model is achieved in that a kind of screw rod sieve, screw rod is a turntable, screw rod connects power driving mechanism through transmission mechanism, have at least 2 screw rods on cabinet, to be arranged in the screw rod working face, there is charging aperture screw rod working face top, screw rod working face below communicates with discharging opening, and screw rod working face front end has material returned passage.
On the basis of technique scheme, the utility model also has following further scheme:
Described transmission mechanism is a jointed gear unit.
Have 2 layers of screw rod working face on the described cabinet at least, the screw rod working face is upper and lower overlaying structure.
Described screw rod working face is a separable structure.
Described screw rod working face below communicates with discharging opening by base.
Have 2 sections screw threads on the described screw rod at least, and constitute 2 above screw rod working faces; The below of every section screw rod working face communicates with corresponding discharging opening.
Advantage of the present utility model is as follows:
Because screw rod is a turntable, screw rod connects power driving mechanism through transmission mechanism, has at least 2 screw rods to be arranged in the screw rod working face on cabinet, and there is charging aperture screw rod working face top, screw rod working face below communicates with discharging opening, and screw rod working face front end has material returned passage; During the screw rod rotation, solid material on the screw rod working face can be advanced by screw rod, solid material can be sized in the process that is advanced by screw rod, the solid material that is sized is from the discharging opening output of screw rod working face below, and the solid material that can not sieve can be from the material returned passage output of screw rod working face front end.The contrast prior art, the utility model has removed " frame is along the stepped setting of the direction of motion of material ", also need not " unit is installed on each grade ladder ".So, after structure of the present utility model is simplified, not only help reducing the manufacturing cost of product, and help reducing fault rate; In addition, the screw rod working face after the simplification is convenient to realize multi-level upper and lower stack, and divides and sift out the suitable solid particle of size.
