Description
Technical field
It the utility model is related to a kind of for being extruded the raw material vinegar sheet for producing acetate fiber to remove before baking
The device of moisture, belong to vinegar sheet extruding drying technology field.
Background technology
Cellulose acetate is that the hydroxyl in cellulose is esterified and generated.It is divided into three according to the difference of acetyl content
Kind：Wherein acetyl content is in 31%-35%, a referred to as cellulose acetate；Acetyl content in 38%-41.5%,
Referred to as cellulose diacetate；When acetyl content is more than 43%, referred to as Triafol T.Cellulose diacetate is commonly called as vinegar sheet.
Vinegar sheet is used to producing the acetate silk of unfiltered cigarette, acetate silk be by vinegar sheet slurries by spinning-drawing machine spinneret and
Into, vinegar sheet is dissolved in the acetone solvent containing a small amount of water, be made into concentration be 22%~30% spinning solution, filtered and deaeration
After send to spinning.
Vinegar sheet is using high-purity bleached wood pulp as raw material, makees acetylizing agent with aceticanhydride, acetic acid makees solvent, in catalyst action
Under, acetylation is carried out to wood pulp cellulose, by pre-processing, acetifying, hydrolyzing, precipitating, washing, extruding, the process such as drying carry out
Production.Specifically production process is：Wood pulp by crushing stirs in preprocessor together with acetic acid, be then fed into acetifier with
Nitration mixture carries out reaction generation and acetifies thing；Reaction adds the vinegar of a certain amount of aqueous acetic acid, acidic catalyst and excess after terminating
Acid anhydride, thing is acetified through hydrolysis generation cellulose diacetate (vinegar sheet)；Again product vinegar is obtained through processes such as precipitating, washing, extruding, dryings
Piece.
Vinegar sheet is before drier is entered, and is typically that first moisture is extruded to improve drying efficiency, but existing
Moisture extruder is typically the gravity extruding moisture of roller rest wheel, and moisture extrusion rate is poor, and vinegar sheet can not be made to obtain segmentation and torn
Split, preferably to make sufficient preparation for drying in next step.
The content of the invention
The utility model is directed to the deficiency of existing vinegar sheet moisture extrusion techniques, there is provided a kind of simple in construction, moisture extrusion effect
Fruit well and can split vinegar sheet vinegar sheet moisture extruding and segmentation integrated device.
Vinegar sheet moisture extruding of the present utility model and segmentation integrated device, using following technical proposals：
The device, including frame, lower roller shaft and upper roll shaft, the top of frame are provided with guide groove, and the upper end of frame is set
There is dipper crowding gear, crane is provided with guide groove, crane is connected with dipper crowding gear；Lower roller shaft is arranged in frame, upper roller
Axle is arranged on crane, and lower roller shaft is in below upper roll shaft；Lower roller shaft is connected with transmission mechanism.
The dipper crowding gear can use hydraulic cylinder, cylinder, electric cylinders etc..
Axially distributed on the lower roller shaft and upper roll shaft to have a roller tooth, the roller tooth in roller tooth and upper roll shaft on lower roller shaft is handed over
Mistake arrangement.The two sides of the roller tooth are inclined-plane, and the inclination angle in opposed roller increment face is 10 degree of -30 degree.It is distributed in the roller tooth
There is a teeth groove, the teeth groove in adjacent roller tooth staggers.
The movement of crane is driven by dipper crowding gear, the gap in adjustment between roll shaft and the roller tooth of lower roller shaft, makes vinegar
Piece is by suitable extruding force.Lower roller shaft rotates under transmission mechanism drive, and vinegar sheet is between upper roll shaft and the roller tooth of lower roller shaft
It is squeezed and kneads and rotated with roll shaft, moisture is extruded, and makes vinegar sheet segmentation tear.In extrusion process, it can pass through at any time
Dipper crowding gear drives crane to move down, to adjust extruding force.
The utility model can adjust the extruding force of vinegar sheet, ensure that moisture extrudes effect, and make vinegar sheet segmentation tear, be
Good basis has been laid in the drying of next step vinegar sheet, reduces energy resource consumption.
Brief description of the drawings
Fig. 1 is the structural representation of the extruding of the utility model vinegar sheet moisture and segmentation integrated device.
Fig. 2 is the structural representation of roll shaft in the utility model.
In figure：1. right shelf, 2. lower roller shafts, 3. lower roll bearings, roll shaft on 4., 5. guide grooves, 6. dipper crowding gears, 7. lower rolls
Tooth, roller tooth on 8., 9. cranes, roller bearing on 10., 11. drives, 12. teeth groove, 13. left framves.
Embodiment
As shown in figure 1, vinegar sheet moisture of the present utility model extruding and segmentation integrated device, including frame, lower roller shaft 2 and on
Roll shaft 4.Frame is divided into left frame 13 and right shelf 1, and the top of left frame 13 and right shelf 1 is provided with guide groove 5, left frame 13 and right shelf 1
Upper end be provided with dipper crowding gear 6.Crane 9 is provided with guide groove 5, crane 9 is connected with dipper crowding gear 6.Pushing machine
Structure 6 can drive crane 9 to be moved up and down in guide groove 5.Dipper crowding gear 6 can use hydraulic cylinder, cylinder, electric cylinders etc..
The both ends of lower roller shaft 2 are arranged on left frame 13 and right shelf 1 by lower roll bearing 3 respectively.The both ends difference of upper roll shaft 4
It is arranged on by upper roller bearing 10 on left frame 13 and the crane 9 of right shelf 1, upper roll shaft 4 can move up and down with crane 9.
One end of lower roller shaft 2 is provided with drive 11, and drive 11 can be sprocket wheel or belt wheel, by Chain conveyer or with biography
It is dynamic to drive lower roller shaft 2 to rotate.
It is axially distributed on lower roller shaft 2 to have lower roller tooth 7.It is axially distributed on upper roll shaft 4 to have upper roller tooth 8.Lower roller tooth 7 and upper
