Description
Technical field
The utility model relates to a kind of efficient Double screw pulp extruder, belongs to herbal extraction equipment technical field.
Background technology
In tobacco sheets by paper making method production process, tobacco black liquid extraction uses the Double screw pulp extruder used in paper technology completely.Be extract black liquor equally, but because raw material is different, product final use is different, therefore still use that Double screw pulp extruder that paper industry uses can not meet that tobacco business is efficient to press master, the rigors of high reliability, each side such as easy to clean.
Feed liquid feeder and the frame of all traditional double acroll press washers are all welded as a whole, after installing upper and lower rack and helical axis, space between lower rack, frame, feed liquid feeder just becomes an enclosure space, unless removed upper and lower rack and helical axis, otherwise the part that cannot thoroughly clean in this enclosure space, so just hinders the application of this equipment in more areas produce.Meanwhile, because upper and lower rack securing member is fastened in frame, and frame lower close by feed liquid feeder, lower rack is caused to dismantle very difficult, after upper rack, antero posterior axis bearing, material feeding box, double-screw shaft all need being removed, could dismantle lower rack, it is very inconvenient to keep in repair.
Through the long-term observation to existing press master working condition, we find that the part near rack in press master extruding back segment cavity can form the fine and close material duricrust of one deck, hinder the outer row extruding slurries, thus affect the mass dryness fraction of extruded material.Section must destroy this fine and close material duricrust after extrusion for this reason, allow and extrude slurries outer row smoothly.
Summary of the invention
The purpose of this utility model is the utility model patent number proposed the present inventor: ZL 2007 20104396.X, the basis that name is called " a kind of double spiral tobacco pulp extruding machine " is improved, after providing a kind of shove, high, the convenient lower rack of material mass dryness fraction value is dismantled, is keeped in repair, and full equipment is without the efficient Double screw pulp extruder at clean dead angle.This equipment is made not only to can be used for the extraction of tobacco material but also can be used as the extraction of Chinese medicinal plant.
The utility model provides a kind of so efficient Double screw pulp extruder, comprise the frame of band cavity, be located at frame cavity top by upper, the extrusion cabin formed after lower filter screen frame connects, the cavity be positioned at below extrusion cabin is liquid collection storehouse, charging aperture is established in one end of described extrusion cabin, the other end establishes discharging opening, the augering screw of the band helical blade that two are driven by engine is provided with in extrusion cabin, augering screw is made up of the isometrical straight section of feed zone and the cone section of compression section and straight section, and the pitch of helical blade on augering screw reduces to compression section gradually from feed zone, it is characterized in that the helical blade outer rim on compression section is arranged at intervals with breach, so that by the setting of this breach, allow material in compression section with extruding, loosen, extrude again, the mode loosened again is extruded, effectively prevent the formation of outer material duricrust, the slurries extruded are allowed to arrange smoothly outward, material mass dryness fraction after effective raising shove.
Be connected to the bottom of band leakage fluid dram bottom described liquid collection storehouse by connector active card, so that after dismantling this bottom as required, convenient lower rack and internals thereof to forming extrusion cabin cleans.
Described coupling assembling comprises and is arranged on the inside flanging in bottom upper end, and this flanging snaps onto on the outside flanging in connector lower end, and the upper end of connector is fixed on liquid collection storehouse bottom outer wall.
Described upper and lower screen holder is made up of filter screen, support, installing plate respectively, and the installing plate of upper and lower screen holder is fixed on the fixed block inside frame by hold-down screw.
The utility model has following advantages and effect: adopt such scheme, the material of shove process back segment squeezed tight is arranged change, namely allow material after extrusion section to extrude, to loosen, to extrude again, mode locking is again extruded, effectively prevent the formation of outer material duricrust, allow and extrude slurries outer row smoothly, effectively material mass dryness fraction after raising shove.Owing to arranging movable bottom bottom liquid collection storehouse, so that as required after dismounting activity bottom, can conveniently the lower rack and internals thereof that form extrusion cabin be cleaned, be keeped in repair, fundamentally eliminate cleaning dead angle, and can from rack the dismounting of bottom.The utility model also can be used for traditional Chinese medicine extraction.
