Part, the superiority and inferiority of structure directly influence whether the separating property of centrifuge.The discharge port section general structure of auger stripper be
Several holes are directly opened in core pipe, material exits into drum inner wall from several holes, due to more than the number of openings and small, causes material
Discharging is uneven, not in time, over time, gambling plug inside auger stripper, centrifugation machine vibration aggravation；Since the size of aperture limits
It makes, the wear-resistant sleeve thickness on discharge port is necessarily limited, causes the abrasion of wear-resistant sleeve, service life reduction.In addition the Taper Pipe of spiral core tuae
For a simple tapers pipe, escape mouth thereon is small, is not easy to quickly flow out from the material that discharge port section returns, also results in spiral
Gambling plug inside discharger.The structure scene uses the several years, all kinds of problems occurs, such as feeds pipe abrasion, spiral small end inner oil seal, axis
Damage, auger stripper gambling plug etc. are held, it is closely related with auger stripper structure through analyzing.
Summary of the invention
The purpose of the present invention is to overcome the shortcomings of the existing technology, provides a kind of screw unloading with material acceleration function
Device.
The purpose of the present invention is achieved through the following technical solutions: a kind of auger stripper with material acceleration function,
Including hollow spiral core tuae and blade, spiral helicine blade, bolt core pipe packet are provided on the circumferential surface of the spiral core tuae
The core pipe major part successively welded, straight tube, discharge port section and Taper Pipe are included, the discharge port section is provided with discharge port, the cone
It has been disposed radially escape hole on pipe, build-up wear-resistant layer is provided on the working face of the blade on the straight tube, the Taper Pipe
Hard alloy blocks are provided on the working face of blade.
Specifically, the discharge port is arc-shaped flared, and from orthodrome to small arc-shaped transition, discharge port is provided with two
A and relative to spiral core tuae axis centre is symmetrical.
Specifically, the discharge port two sides are circular arc flow-passing surface, are provided with wear-resisting tile on circular arc flow-passing surface.
Specifically, the escape hole is arranged there are three and is mutually perpendicular to.
Specifically, the hard alloy blocks are welded on the working face of blade.
The invention has the following advantages that present invention efficiently solves the discharging of centrifuge auger stripper is uneven, it is too late
When, wear-resistant sleeve is not wear-resisting, all kinds of problems of auger stripper gambling plug.Auger stripper, which has, accelerates discharging functions；Can according to from
The protective cases such as scheming use occasion selection installation monolith hard alloy watt, hardfacing alloy, stainless steel watt, improve the service life；Open type
The problem of discharge port and roomy formula escape mouth have prevented auger stripper discharge port gambling plug completely.

Specific embodiment
The present invention will be further described with reference to the accompanying drawing, but protection scope of the present invention is not limited to following institute
It states.
As shown in figs. 1 to 6, a kind of auger stripper with material acceleration function, including hollow spiral core tuae 1 and leaf
Piece 2, spiral helicine blade 2 is provided on the circumferential surface of the spiral core tuae 1, and blade 2 is welded on spiral shell after forming by a constant pitch
It revolves in core pipe 1, bolt core pipe 1 includes core pipe major part 5, straight tube 6, discharge port section 7 and the Taper Pipe 8 successively welded, the discharging
Mouth section 7 is provided with discharge port 10, and escape hole 9, the work of the blade 2 on the straight tube 6 have been disposed radially on the Taper Pipe 8
Build-up wear-resistant layer 3 is provided on face, build-up wear-resistant layer 3 is welded in the work of nonabradable straight section blade 2 by carbide electrode heap
Make on face, it is ensured that the abrasion-proof corrosion-proof of auger stripper is provided with hard alloy blocks 4 on the working face of the blade 2 of the Taper Pipe 8.
Further, the discharge port 10 is arc-shaped flared, from orthodrome to small arc-shaped transition, has and accelerates function
Can, it flows outwardly material quickly from rotation center, increases residence time of the material in bowl, discharge port 10 is arranged
There are two and axis centre relative to spiral core tuae 1 it is symmetrical, have space big, the big advantage of flow velocity, discharging direction
It is related to auger stripper direction of rotation, material can be made to accelerate to flow out along arc section, without any dead angle, material outlet is smooth, can
The problem of preventing auger stripper discharge port gambling plug completely.
Further, 10 two sides of discharge port are circular arc flow-passing surface, are provided with wear-resisting tile on circular arc flow-passing surface, can
The protective cases such as installation hard alloy watt, hardfacing alloy, stainless steel watt are selected according to centrifuge use occasion.
Further, the advantages of escape hole 9 is arranged there are three and is mutually perpendicular to, the structure is to prevent discharge port 7
The material of return enters in Taper Pipe 8 and can not be discharged, and unobstructed escape mouth 9 can make the material returned quickly flow out Taper Pipe 8, can be complete
The problem of preventing the gambling plug of auger stripper discharge port 10 entirely.
Further, the hard alloy blocks 4 are welded on the working face of blade 2, hard alloy blocks 4 and stainless steel
After being riveted together by screw, it is welded on blade 2 together.
The course of work of the invention is as follows: the mixture of solid phase and liquid phase enters helix core through the feed end of spiral core tuae 1
Pipe 1, mixture enter discharge port section 7,1 high speed rotation of spiral core tuae through spiral core tuae 1, and mixture flies through 10 spiral of discharge port
Out, because discharge port 10 is arc-shaped flared, material can be made to accelerate to flow out along arc section, without any dead angle, material outlet is smooth,
The problem of can preventing auger stripper discharge port gambling plug completely.
The above, only presently preferred embodiments of the present invention not do limitation in any form to the present invention.It is any ripe
Those skilled in the art is known, without departing from the scope of the technical proposal of the invention, all using technology contents described above
