Description
Technical field
The utility model relates to a kind of horizontal screw unloading centrifuge, is applicable to industries such as chemical industry, sewage disposal, medicine.
Background technology
During alumina by sintering is produced, generally adopt separating tank to carry out the red mud that sodium aluminate solution goes out slurries and separate,, be prone to reversible reaction, reduced the dissolution rate of sodium aluminate because disengaging time is longer with thick liquid.The red mud that the sodium aluminate solution of employing horizontal screw unloading centrifuge realization high concentration goes out slurries separates fast with thick liquid, it is a kind of new trial of in alumina producing, using, can improve the dissolution rate of sodium aluminate solution greatly, but this centrifuge only is applicable to materials such as sewage disposal and is difficult for the operating mode of crystallization, and is then inapplicable for easily-crystallized stocks such as alkalescence.This centrifuge bearing seal has just been adopted the felt sealing at the two ends of housing, and the material of this commute crystallization does not have the effect of sealing basically, and material easily causes the damage of bearings at two ends, causes centrifuge to shut down, and can not adapt to the macrocyclic production of continuity.
Summary of the invention
The purpose of this utility model is the deficiency that exists at said apparatus, proposes a kind of horizontal screw unloading centrifuge that red mud, alkali lye and bearing is kept apart reduce damage of bearings; Another purpose is the deficiency that exists at said apparatus, and it is unimpeded at the centrifuge inner flow passage to propose a kind of material, and resistance is little, reduces the horizontal screw unloading centrifuge of the wearing and tearing of centrifuge charging aperture.
A kind of horizontal screw unloading centrifuge comprises:
Bearing block-be positioned at the two ends of this centrifuge is supported on the basis;
Centrifugal reel-its shape is that the front portion is divided into circular cylinder body, the rear portion is divided into the conical shell that has slag-drip opening, its circular cylinder body front end is connected with the welding neck flange that is circumferentially with liquid outlet, the end of its conical shell is connected with welding neck flange, the welding neck flange at its two ends by bearings on bearing block;
Discharge auger-be is by hollow shaft and the cored screw axle that is welded with the outer flight of hollow shaft, the flight of front end is that isometrical external diameter constitutes cylindrical interface, the flight of rear end constitutes the cone conical interface for formula external diameter decrescence, discharge auger places in the centrifugal reel, its hollow shaft two ends by bearings on the welding neck flange inwall at centrifugal reel two ends;
The outlet that feed pipe-entrance point has adpting flange is the steel pipe of taper, places in the hollow shaft of discharge auger, is fixed on the bearing block by adpting flange;
Two semicircles of protective cover-be are affixed to become a whole cylindrical shell that two ends are with holes, and this protective cover is supported on the support;
It is characterized in that it also comprises:
Blocking material ring-be two annular slabs made from steel plate, the inner periphery of annular slab is welded on the neck of centrifugal reel two ends welding neck flange respectively;
Blowpit-be two circular troughs that are welded with steel plate, be welded on respectively in two stomidiums of protective cover, cover on the blocking material ring;
Guiding awl-to be shaped as the top be the conical steel body that pointed high-abrasive material is made for it, is welded on the discharge auger hollow shaft middle part of feed pipe outlet position, opposite.
Owing to adopted bearing protection structure and reduced charging aperture wearing and tearing structure, prevented that red mud, alkali lye from entering bearing, reduced the resistance when material enters in the centrifuge, runner is unimpeded, and is stable, and long service life can be produced continuously.

The specific embodiment
A kind of horizontal screw unloading centrifuge comprises: bearing block 1-is positioned at the two ends of this centrifuge, is supported on the basis; Its shape of centrifugal reel 6-is that the front portion is divided into circular cylinder body, the rear portion is divided into the conical shell that has slag-drip opening, its circular cylinder body front end is connected with the welding neck flange that is circumferentially with liquid outlet, the end of its conical shell is connected with welding neck flange, the welding neck flange at its two ends by bearings on bearing block; Discharge auger 7-is by hollow shaft and the cored screw axle that is welded with the outer flight of hollow shaft, the flight of front end is that isometrical external diameter constitutes cylindrical interface, the flight of rear end constitutes the cone-shaped interface for formula external diameter decrescence, discharge auger places in the centrifugal reel, its hollow shaft two ends by bearings on the welding neck flange inwall at centrifugal reel two ends; The outlet that feed pipe 2-entrance point has adpting flange is the steel pipe of taper, places in the hollow shaft of discharge auger, is fixed on the bearing block by adpting flange; Protective cover 4-is that two semicircles are affixed becomes a whole cylindrical shell that two ends are with holes, and this protective cover is supported on the support; It is characterized in that it also comprises: blocking material ring 13-is two annular slabs made from steel plate, and the inner periphery of annular slab is welded on the neck of centrifugal reel two ends welding neck flange respectively; Blowpit 3-is two circular troughs that are welded with steel plate, is welded on respectively in two stomidiums of protective cover, covers on the blocking material ring; Guiding awl 14-its to be shaped as the top be the conical steel body that pointed high-abrasive material is made, be welded on the discharge auger hollow shaft middle part of feed pipe outlet position, opposite.
A kind of structure of novel horizontal helical-conveyer centrifugal as shown in Figure 1.It partly is made up of bearing block 1, feed pipe 2, blowpit 3, protective cover 4, centrifugal reel 6, discharge auger 7, charging aperture 8, shelves material ring 13, guiding awl 14 etc.The material that need to separate from feed pipe 2 through charging aperture 8, guiding through guiding awl 14 enters centrifugal reel 6 inside, material relies on centrifugal force to finish separation in centrifugal reel 6, the slag that effluxes to need on stillness of night at centrifugal reel center and its drum wall to appear, under the effect of discharge auger 7, slag on the centrifugal reel wall is discharged from slag-drip opening 10, and filtrate is then flowed out through filtrate collection mouth 12 from filtrate (liquid 5 and entered flow process.From the slag of slag notch discharge and the filtrate of filtrate (liquid discharge; because of centrifugation effect can be leaked to two ends along discharge auger; through stopping of shelves material ring 13; simultaneously under the effect of blowpit 3; can guarantee all to stop and in blowpit is discharged to protective cover 4, played the effect of protection bearing along the material that discharge auger leaks.The material channeling conduct that 14 of guiding awls will be sent into feed pipe 2 reduces material and forms vortex at charging aperture, avoids quickening the wearing and tearing of charging aperture 8.Numbering 9 is for inserting the import of fast device oil circuit among the figure, and numbering 11 supports for vibration damping.
