The black liquor seperator
Affiliated technical field
The utility model relates to a kind of seperator, especially for the horizontal seperator of black liquor processing.
Background technology
At present, horizontal seperator is adopted in the processing of the black liquor that is produced in the paper-making process usually.The structure of traditional horizontal seperator is: in the tubular knockout drum helical blade is housed, during separation, black liquor is by the extruding of knockout drum inwall and helical blade, and the realization Separation of Solid and Liquid, thereby the inwall machining accuracy of knockout drum is higher, the processing technology complexity; And since the abrasive action of material, the parts rapid wear, and separating effect is not satisfactory, operating efficiency is lower.People transform traditional seperator for this reason, are 97244796.2 " high consistency slurry separators " and 99224599.0 " co-rotating twin screw press masters " as the disclosed patent No. of Chinese patent.Though above-mentioned two patented technologies have adopted inwall perforate technical scheme, have improved separative efficiency, have reduced the speed of service, also exist following shortcoming: complex structure, produce more with material, make loaded down with trivial details; Transmission link is more during use, and power consumption is bigger; When breaking down, be difficult to maintenance.
Summary of the invention
Be its complex structure of horizontal seperator that overcomes prior art, the problem that separating effect is relatively poor and efficient is lower, it is a kind of simple in structure, easily manufactured, for ease of maintenaince that the utility model provides, and good separating effect and the high black liquor seperator of separative efficiency.
The technical scheme that its technical problem that solves the utility model adopts is: it mainly is made up of frame, motor, hood, filter cylinder, screw-conveyer-shaft and packing auger blade; The two ends of filter cylinder place on the frame that is fixed on the support; Filter cylinder is equipped with hood outward; Filter cylinder is built-in with the screw-conveyer-shaft that has the screw auger blade and link to each other with motor; Filter cylinder and hood one end top are provided with charging aperture, and its other end is provided with discharging opening; The bottom of hood also is provided with leakage fluid dram.
Be provided with several filter openings on the stack shell of above-mentioned filter cylinder equably, its inwall is provided with screen cloth.
Between filter cylinder and hood, be provided with scavenge pipe.
The beneficial effects of the utility model are: simple in structure, easily manufactured, for ease of maintenaince, good separating effect, power consumption is low and separative efficiency is high.

The specific embodiment
Below in conjunction with drawings and Examples the utility model is further specified.
The utility model mainly is made up of support 1, frame 2, motor 11, hood 8, filter cylinder 6, screw-conveyer-shaft 9 and packing auger blade 5; Two frames 2 longitudinally are fixed on the horizontal support 1, and the two ends of filter cylinder 6 place on the frame 2; Be provided with several equal-sized filter openings on the stack shell of filter cylinder 6 equably, the inwall of filter cylinder 6 is equipped with the steel screen cloth 13 that opening diameter does not wait, and the outer race of filter cylinder 6 is equipped with hood 8; Filter cylinder 6 and hood 8 one end tops are provided with charging aperture 4, and its other end is provided with discharging opening 12; The bottom of hood 8 also is provided with leakage fluid dram 14, is provided with scavenge pipe 7 between filter cylinder 6 and hood 8.Filter cylinder 6 is built-in with the screw-conveyer-shaft 9 that has screw auger blade 5, and the pitch of screw auger blade 5 tapers off from charging aperture 4 to discharging opening 12; Screw-conveyer-shaft 9 is fixed by bearing block and support 3 thereof, and an end of screw-conveyer-shaft 9 links to each other with motor 11 by drive 10 and the driving belt on it.
During work, black liquor to be separated enters in the filter cylinder 6 by charging aperture 4, and black liquor flows into hood 8 by screen cloth 13 and filter cylinder 6, discharges from leakage fluid dram 14; The squeezing action of the screw-conveyer-shaft 9 of the higher black liquor of concentration by power is provided by motor 11, helical blade 5 and filter cylinder 6, black liquor is further concentrated, the paper pulp slag that last moisture content is lower is discharged from discharging opening 12, thereby realizes the Separation of Solid and Liquid of black liquor.Because the paper pulp slag easily stops up the screen cloth 13 in the filter cylinder 6, thereby the utility model should wash with 7 pairs of screen clothes 13 of scavenge pipe after operation a period of time in good time.After the operation, damage if find screen cloth 13 when long, detachable lower machine cover 8 adds at filter cylinder 6 stack shells of screen cloth 13 breakages and to mend screen cloth and get final product.
