Abstract
The utility model relates to a screw pulp dewatering machine, which is especially suitable to concentrate and scrub the low-concentration pulp in the waste paper processing system of the pulp and paper making industry. End section screws are connected via an expanding sleeve to comprise a screw main shaft together with an inner filtering drum; the screw main shaft is fixed on a machine casing via both-end bearing seats and arranged on a machine base. The machine casing is provided with a pulp inlet; the machine base is provided with a liquid filtering outlet; after the pulp is extruded by the screw main shaft, the generated filter liquid is exhausted from the liquid filtering outlet on the machine base. The position of the pulp outlet is provided with a pneumatic back-pressure push disk; the opposite pushing force is adjusted, and the pulp outlet concentration can be controlled, and the pulp outlet concentration is caused to be kept stable; the main shaft is provided with the inner filtering drum used for removing the water in the pulp layer, and the consistence between the inside dewatering and outside dewatering in the pulp layer is ensured. The effects are that the screw pulp dewatering machine has simple structure, convenient repairing and changing the spiral shaft; the adopted entire screw shaft is that the root cylinder and the screw pitch are changed; the screw pulp dewatering machine has bigger compression ratio and high production capability, and is widely used for condensing and scouring the low-concentration pulp in the waste paper processing system of the pulp and paper making industry.
Description
Affiliated technical field:
The utility model relates to a kind of acroll press washer, is particularly useful in the pulping and paper-making industry Waste Paper Handling system low underflow material being concentrated and washing.
Background technology:
Prior art is to utilize acroll press washer that low underflow material is carried out concentration.It mainly utilizes the compression ratio of spiral that slurry is concentrated, and specification is less, and output is also less, and pulp concentration is low and unstable; Helical axis is an integral body, and whole helical axis all will be changed after a certain section wearing and tearing, the maintenance cost height, and along with the increasing of production capacity, this structure can not strengthen again.
Summary of the invention:
The purpose of this utility model provides a kind of acroll press washer, and it is that the whole helical axis of employing is to become root footpath, varying pitch, has bigger compression ratio; The latter end spiral is connected on the main shaft by expansion set, and it is convenient to change; At the spiral the tip of the axis interior filter drum is housed.
The utility model acroll press washer takes following technical scheme to realize, it partly is made up of support, casing, screw spindle, filter drum, back-pressure push-plate etc.Screw spindle is fixed on the casing by the bearing block at two ends, is installed on the support, and latter end spiral and interior filter drum are housed on the screw spindle, is fastened on the screw spindle by expansion set, and casing is provided with stock inlet, and support is provided with filtrate (liquid; The filtrate that produces after the screw spindle extruding slurry is discharged by the filtrate (liquid on the support.Slurry enters filter drum by stock inlet, constantly dehydration under screw extrusion with big compression ratio, and be transported to the discharge of grout outlet place; The filtrate of extruding from slurry is passed filter drum and is entered water receiving tank on the support, is pooled to filtrate (liquid and flows out.Be provided with pneumatic back-pressure push-plate at the grout outlet place, regulate anti-pushing force, the controlled slurry concentration of making makes pulp concentration keep stable; Main shaft is provided with interior filter drum, as removing the inner moisture of slurry layer, has guaranteed that the inside and outside dehydration of slurry layer is consistent.
The effect of the utility model acroll press washer is simple in structure, and the maintain and replace helical axis is convenient, and adopting whole helical axis is to become root footpath, varying pitch, has bigger compression ratio; The latter end spiral is connected on the main shaft by expansion set, at the spiral the tip of the axis interior filter drum is housed, and is widely used in the pulping and paper-making industry Waste Paper Handling system low underflow material is concentrated and washs.
