Description
Technical field
The present invention relates to a kind of twin-screw rinsing maching.
Background technology
In the paper-making pulping field, chemical-mechanical pulping field particularly, the chemical treatment meeting produces a large amount of hydrotropes and chemical extract in the pulping process, also can be present in before the washing in the string mill disposed slurry, slurry must be got rid of the aforementioned hydrotrope and chemical extract before being copied paper by the clear water mode of washing, otherwise can have a strong impact on the paper product quality and manufacture paper with pulp.In order to reduce pollution, ton plasm scouring water consumption, national standard is at reduced year by year, and environmental protection policy is more and more stricter, is badly in need of high-efficient washing equipment, more and more comes into one's own as a kind of important pulping equipment.At present, slurry washing machine class is various, and spiral shove washing facility mainly contains single-screw extruding thickener and Double screw pulp extruder.Structure is that the housing that comprises screw rod is the perforate filter structure, after the slurry of concentration lower (3-4%) enters press master after the dilution, gradually the water in the slurry is extruded than (be that volume diminishes gradually, realize compression) by screw compression, reaches the washing purpose.Unit detersive efficiency (being wash degree) is lower, and many series connection just can be finished.Become the high major reason of the water consumption amount of disappearing.
Summary of the invention
The object of the invention is to address the above problem, and a kind of twin-screw rinsing maching of high-efficiency water-saving is provided, and is specifically realized by following technical scheme.
A kind of twin-screw rinsing maching, described twin-screw rinsing maching comprises frame, receiving hopper, warehouse, two bull sticks, some groups are washed the screw casing unit and filter castor, described warehouse is arranged on the frame, this warehouse inside is provided with two described two bull sticks of through hole parallel to each other and is arranged on rotationally described through hole, described some groups of washing screw casing unit are fixedly sleeved on bull stick successively, described washing screw casing unit comprises conveyor screw cover and reverse extrusion screw casing, the pitch of described reverse extrusion screw casing is less than conveyor screw cover and opposite with the hand of spiral of conveyor screw cover, warehouse one end is provided with charging aperture, the other end is provided with discharging opening, described receiving hopper is communicated with charging aperture, described warehouse top is provided with the clear water hole corresponding with the conveyor screw cover, the warehouse bottom is provided with the limber corresponding with the reverse extrusion screw casing, and described filtration castor is arranged on warehouse part corresponding to limber.
Described twin-screw rinsing maching, it further designs and is that described washing screw casing unit has 6 groups, is provided with successively 3 groups of washing screw casing unit on the every bull stick.
The present invention has adopted the twin-screw multistage washing, by adopting some groups of conveyor screw covers in warehouse, to form a plurality of low-pressure areas and higher-pressure region with the reverse extrusion screw casing, after fully absorbing clear water by material, in the higher-pressure region moisture in the material is extruded low-pressure area, realized the repeatedly high-efficient washing in the single device, and water consumption is less, comparatively energy-conserving and environment-protective.
Description of drawings
Fig. 1 is structural representation of the present invention.
Fig. 2 is the plan structure schematic diagram of twin-screw rinsing maching shown in Fig. 1.
The specific embodiment
Below in conjunction with Figure of description and specific embodiment the present invention is further specified.
This twin-screw rinsing maching comprises frame (not shown in FIG.), receiving hopper 1, warehouse 2, two bull sticks 3, some groups of washing screw casing unit 4 and filters castor 5, warehouse 2 is arranged on the frame, this warehouse inside is provided with two two bull sticks of through hole (not shown in FIG.) parallel to each other and that be communicated with and is arranged on rotationally through hole (not shown in FIG.), 6 groups of washing screw casing unit are fixedly sleeved on two bull sticks successively, are provided with successively 3 groups of washing screw casing unit on the every bull stick.
Washing screw casing unit 4 comprises conveyor screw cover 41 and reverse extrusion screw casing 42, and the pitch of reverse extrusion screw casing is less than conveyor screw cover and opposite with the hand of spiral of conveyor screw cover, and the length of conveyor screw cover is longer than the reverse extrusion screw casing.Warehouse 2 one ends are provided with charging aperture 21, the other end is provided with discharging opening 22, receiving hopper 1 is communicated with charging aperture, warehouse top is provided with the clear water hole 23 corresponding with the conveyor screw cover, the warehouse bottom is provided with the limber corresponding with the reverse extrusion screw casing 24, filters castor and is arranged on warehouse part corresponding to limber.
As shown in the figure, twin-screw externally rotates under the driving of driving mechanism, after material enters warehouse 2 by receiving hopper 1, under the effect of conveyor screw cover 41, meet with reverse extrusion screw casing 42, conveyor screw cover 41 is opposite with the direction of transfer of 42 pairs of materials of reverse extrusion screw casing, in both junctions material is fully pushed, and forms the higher-pressure region at this, material is pressed dry, and sewage is discharged from limber 24 after filtering castor; Along with the material that enters feed bin constantly increases, and the reverse extrusion screw casing is shorter, material contacts by the conveyor screw cover 41 of the helicoid on the reverse extrusion screw casing with next washing screw casing unit 4, at this moment, material enters a relative low-pressure area, outside measuring pump injects clear water in the warehouse by the clear water hole, the material that press dry absorbs suitable clear water, again meet with the reverse extrusion screw casing of this washing screw casing unit 4 and again pressed dry, then enter next washing screw casing unit 4, repeat above-mentioned steps, material repeatedly flooded by clear water and press dry after wherein sewage and water-soluble substances all be washed and discharge from discharging opening 22 after clean.
The present invention has adopted the twin-screw multistage washing, by adopting some groups of conveyor screw covers in warehouse, to form a plurality of low-pressure areas and higher-pressure region with the reverse extrusion screw casing, after fully absorbing clear water by material, in the higher-pressure region moisture in the material is extruded low-pressure area, realized the repeatedly high-efficient washing in the single device, and water consumption is less, comparatively energy-conserving and environment-protective.
