Abstract
The utility model discloses a grading-type horizontal spiral discharging centrifuge, and the centrifuge comprises a centrifuge body which is equipped with a grading device. The grading device comprises a rotary drum. The interior of the rotary drum is provided with a spiral discharging device which is provided with a vertical baffle plate. The vertical baffle plate divides a spiral channel of the spiral discharging device into a high-speed zone and a low-speed zone. An annular channel is formed between the vertical baffle plate and the inner wall of the rotary drum. Compared with a common horizontal spiral centrifuge, the width of a technology belt of the grading-type horizontal spiral discharging centrifuge is reduced from 15 microns to about 5 microns, the number of big particles in original small particles is reduced by a haft, the number of small particles in big particles is reduced by one third, so the grading effect is better.
Description
Technical field
The utility model relates to a kind of centrifuge, is a kind of Horizontal spiral discharging centrifuge specifically.
Background technology
Industrial have many materials as kaolin, titanium dioxide, and the industries such as chalk, adopt conventional two-phase horizontal spiral discharge sedimentation centrifuge in the time of need to carrying out classification processing.Utilize the separation factor of this centrifuge and the cooperation of draw ratio to realize solid phase particles classification, both big particle had separating effect fine particle there is no separating effect.But horizontal spiral discharge sedimentation centrifuge is due to the stirring of spiral, and middle corase particles is difficult to settle down and is taken away by slurry, and parts of fine particle is entrained in middle corase particles, from slag-drip opening, discharges.Classification efficiency is very poor, and grading technology band is narrow.
Utility model content
Goal of the invention: for the problem and shortage of above-mentioned existing existence, the purpose of this utility model is to provide a kind of stagewise Horizontal spiral discharging centrifuge.
Technical scheme: a kind of stagewise helical-conveyer centrifugal, comprise centrifuge body, in described centrifuge basis, be also provided with grading plant, described grading plant comprises rotary drum, in this rotary drum, be provided with auger stripper, described auger stripper is provided with vertical baffle the helical duct of auger stripper is divided into quick district and district at a slow speed; Between the inwall of this vertical baffle and rotary drum, form circular passage.
Wherein, the discharger that the auger stripper in district is ribbon spiral at a slow speed.
Wherein, in order to make second auger stripper in district at a slow speed more stable, in district, be also provided with at a slow speed the blade of brace rod support helix discharger.
Wherein, in order to make discharging faster, grading effect is more stable, the discharging opening that the discharging opening of rotary drum is double material.
Beneficial effect: the utility model is compared former common horizontal screw centrifuge, technique bandwidth eases down between 5 microns by 15 microns, in former granule, containing bulky grain amount, reduces half, and containing granule, also reduces approximately 1/3 in bulky grain, and grading effect is more accurate.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
With reference to Fig. 1, a kind of stagewise helical-conveyer centrifugal, comprise centrifuge body, in described centrifuge basis, be also provided with grading plant, described grading plant comprises rotary drum 1, in this rotary drum 1, be provided with auger stripper 2, described auger stripper 2 is provided with vertical baffle 3 helical duct of auger stripper 2 is divided into quick district 4 and district 5 at a slow speed; Between the inwall of this vertical baffle 3 and rotary drum 1, form circular passage 6.
Wherein, the discharger that the auger stripper 4 in described district at a slow speed 3 is ribbon spiral.
Wherein, described district at a slow speed 3 is also provided with the blade of brace rod 7 support helix dischargers 2.
Wherein, the discharging opening that the discharging opening of described rotary drum 1 is double material.
During the utility model work, slip enters auger stripper by feed pipe, first enter into the high velocity of auger stripper helical duct, slip is flow at high speed in the high velocity of auger stripper, under centrifugal action, macroparticle in slip is deposited on drum inner wall, and auger stripper can be discharged the corase particles of preliminary classification outside rotary drum.
The slip of separated macroparticle flows into district at a slow speed from the circular passage of baffle plate and drum inner wall, a baffle plate part is immersed in liquid pool, with in, the slip of fine particle is by behind circular passage, flow area increases approximately 15 times suddenly, thereby flow velocity reduction, and district is used ribbon spiral at a slow speed, to slurry, stirs little, medium like this particle also can settle down, and by ribbon spiral, is released.
In process of the test, the particle of weight phase is carried out to passed examination rate.Again the ratio of the particle of slip is adjusted commissioning device again, the technique band scope that inspection machine adapts to.
The foregoing is only better embodiment of the present utility model; protection domain of the present utility model is not limited with above-mentioned embodiment; in every case the equivalence that those of ordinary skills do according to the utility model institute disclosure is modified or is changed, and all should include in the protection domain of recording in claims.
