The rotor (auger stripper) of axis rotation, First Speed and second speed are not both to be generated by differential mechanism, so as to realize
Continuous operation.
Auger stripper is usually made of a core cylinder and one group of spiral blade being welded on above, spiral
Blade blows the solid phase being deposited on cylinder inboard wall off.There is one group of radial screw feed en-trance in the centre of core cylinder, and one non-rotary
Along core cylinder axis of rotation reaches near screw feed en-trance feed pipe, and mixed liquor to be processed passes through screw unloading through feed pipe
The screw feed en-trance of device enters in cylinder.To this section for having screw feed en-trance for the auger stripper core cylinder for having special designing
Structure is referred to as accelerator.Herein, linear motion liquid inject core cylinder, by high-speed rotating core cylinder drive rotate, from
Under mental power function, liquid is entered in centrifugation machine drum body by the screw feed en-trance of accelerator.Obviously, liquid to form spiral shell herein
The trend of linear waterpower movement.The polar coordinates mathematical description of the helical is approximately：It is one around pole is zero with initial angular velocity
On the ray of constant angular acceleration rotation, with the track of the point of the certain variable accelerated motion of initial velocity, fluctuating acceleration therein refers to
With radius and the increased centrifugal acceleration of angular speed.
Over time, screw feed en-trance just generates very big abrasion, to influence the normal work of centrifuge.To slow down urgency
Abrasion of the fast logistics to screw feed en-trance, majority centrifuge manufacturer generallys use resistance in one layer of screw feed en-trance spraying at present
Grind material, since the wear-resistant material layer of spraying is relatively thin, along with the bonding force of spraying is slightly worse, to improve its wear-resisting property effect not
It is very ideal.If the abrasion of screw feed en-trance is more serious, screw feed en-trance must just be repaired, if this repair shows in user
Field carries out, due to being limited by its execution conditions, it is difficult to complete to repair at user scene, be typically necessary the life for transporting centrifuge back
It produces producer to be repaired, this just necessarily extends repair time, increases freight, brings great inconvenience to users, together
When also increase the burden of user.

Screw feed en-trance, the screw feed en-trance is arc-shaped flared, and seamlessly transits with distribution cavity, the screw feed en-trance and cloth
The junction of material chamber is provided with abrasion-proof stick.
Preferably, axis centre of the quantity of the screw feed en-trance for two and relative to mandrel is symmetrical.
Preferably, another part circumferential surface exposes to spiral shell in a part of circumferential surface insertion screw feed en-trance of the abrasion-proof stick
Precession material mouth.The mounting structure of abrasion-proof stick is reliable and stable.
Further, one end of the accelerator has charging baffle, and the other end has sealing plate, one end of the abrasion-proof stick
It across charging baffle and is located on sealing plate, is provided with fixed plate on the outside of the charging baffle, the fixed plate passes through fastening
Screw is fixed on charging baffle for compressing abrasion-proof stick, and the fixed plate is fixed abrasion-proof stick by fixing screws.Disassembly and
Easy to assembly quick, the fixing-stable of abrasion-proof stick is reliable, and cost is relatively low.
Beneficial effect：The wear-resistant protection auger stripper of the replaceable accelerator of the utility model, because screw feed en-trance is set
It is equipped with abrasion-proof stick, reduces the rate of wear of accelerator, extends the service life of accelerator, reduces the maintenance of accelerator more
It changes this into, reduces working hour and human cost；Easy to assembly quick, the side not high to machining accuracy and installation requirement of abrasion-proof stick
Just it fabricates, cost is relatively low, does not influence equilibrium problem completely after replacing wear-resisting handful, greatly shortens replacing construction.

Specific embodiment
Embodiment
As shown in Figures 1 to 3, a kind of wear-resistant protection auger stripper of replaceable accelerator including hollow mandrel 1 and is set
The spiral helicine pusher blade 2 on 1 circumferential surface of mandrel is set, the mandrel 1 is rotatably arranged in rotary drum 3, the inner cavity of the mandrel 1
In be provided with accelerator 4, offer distribution cavity 41 in the accelerator 4, one end of the distribution cavity 41 and the inner cavity of mandrel 1 connect
It is logical, the screw feed en-trance 42 being connected to respectively with distribution cavity 41 and rotary drum 3, the spiral are offered on the side wall of the accelerator 4
Axis centre of the quantity of feed inlet 42 for two and relative to mandrel 1 is symmetrical, and the screw feed en-trance 42 is arc-shaped
Flared, and seamlessly transitted with distribution cavity 41, the junction of the screw feed en-trance 42 and distribution cavity 41 is provided with abrasion-proof stick 5.
In order to which firm, function-stable when use is stablized in the installation of abrasion-proof stick 5, a part of circumferential surface of the abrasion-proof stick 5 is embedded in screw feed en-trance
In 42, another part circumferential surface exposes to screw feed en-trance 42.
In order to keep abrasion-proof stick 5 quick and easy for installation, fixing-stable is reliable, and one end of the accelerator 4 has charging baffle
44, the other end has sealing plate 45, and rotary drum 3 includes cylindrical tube interconnected and frustum of a cone cylinder, 44 court of charging baffle
