Abstract
The utility model relates to a pulp grinder used in pulp beating and pulping, particularly a medium concentration pulp grinder for pulp of medium concentration of 5-15%. The medium concentration pulp grinder comprises a grinding chamber composed of a machine shell, a grinding disc arranged in a pulping chamber, and a pulp advancing mechanism, wherein, a movable grinding disc is arranged on a cantilever end of a rotary main shaft inside the pulping chamber, and the pulp advancing mechanism is arranged on the same rotary main shaft and positioned at the front part of the movable grinding disc. With simple structure, the pulp grinder is suitable for grinding pulp of various materials and forms, and with reliable work, the utility model can reduce power consumption.
Description
The utility model relates to a kind of employed fiberizer of every profession and trade defibrination slurrying that is widely used in, be specially adapted to beating consistency and be the fiberizer of 5~15% middle concentration slurry.
In pulping process, be commonly the low concentration making beating at present.And use the low concentration fiberizer, and shown by various experiments that the low concentration making beating is cut staple exceedingly, cause final products to comprise that physical property such as tensile strength is generally on the low side, and energy consumption is big; If directly the above slurry of centering concentration or middle concentration is pulled an oar, the physical property of its product obviously is better than the low concentration making beating.But there is certain technical problem in concentration defibrination in realizing, because slurry concentration height causes difficult feed, also easily because of hard foreign material card machine, damages parts.Therefore up to the present, middle concentration fiberizer is still a technological gap.
Goal of the invention of the present utility model is to provide the middle-density refiner that the concentration slurry is fully pulled an oar in a kind of can successfully the realization.
The middle-density refiner that the utility model is designed, its technical characterstic is that its overall technical architecture is: this fiberizer comprises defibrination chamber and the indoor mill of defibrination that is made of casing, movable grinding disc in the mill is installed in the cantilever end that rotary main shaft is positioned at the defibrination chamber, also includes to be installed on the slurry propulsive mechanism that same rotary main shaft is positioned at the mill front portion.
In technique scheme, the slurry propulsive mechanism is made up of the screw auger and the wing wheel that are installed on rotary main shaft movable grinding disc front end, and its rotating grinding board can be plane mill or taper rubbing disc.When movable grinding disc was selected taper rubbing disc for use, its slurry propulsive mechanism also can be reduced to the screw auger that is installed on main shaft taper rubbing disc front portion.In these two kinds of implementer's cases, the helical blade of screw auger and pan feeding horizontal tube inwall are tangent.
Middle-density refiner provided by the utility model, by the slurry propulsive mechanism rotary power of rotary main shaft is become radial push power, the slurry that denseness is higher is constantly pushed in the abrasive disk space, the making beating operation is finished in brute force friction between main dependence fiber and the fiber, realize that slurry concentration is the making beating operation of 5~15% middle concentration slurry, its range of application is wide, and the raw material of applicable various material, shape.Solve charging, crude fibre and twined technical problems such as causing the card machine.Products such as copying the system corrugated paper can be directly used in by the slurry after the making beating of this equipment, the production technology of some product can be simplified effectively; Its reliable operation, efficient height, low dense fiberizer economize on electricity is at least 40%, and the slurry beating degree after the making beating is equivalent to the work effect after the low dense fiberizer series connection more than two or two, and simple and reasonable for structure, is easy to dismounting, keeps in repair.
Describe technology contents of the present utility model in detail below in conjunction with accompanying drawing.
Fig. 1, Fig. 2 are respectively the two example structure schematic diagrames of this middle-density refiner
Fig. 3 is the structural representation of slurry propulsive mechanism in the middle-density refiner
Fig. 4 is the A-A generalized section of Fig. 3.
The design's middle-density refiner includes the mill in the defibrination chamber 7 that is made of casing and the defibrination chamber 7, movable grinding disc 5 wherein is installed on rotary main shaft 8 and is positioned on the cantilever end of defibrination chamber 7, movable grinding disc 5 is by be fixedly connected abrasive disk seat 6 on rotary main shaft 8 of cone key, be installed on the rotary main shaft 8, movable grinding disc 5 is bolted on the abrasive disk seat 6, and cooperates mill to separate with bolting in the static cutting disk 4 of defibrination chamber 7 inwalls.Among the embodiment as shown in Figure 1, slurry propulsive mechanism before being positioned at abrasive disk seat 6 on the rotary main shaft 8 is to be made of screw auger 2 and wing wheel 10, spiral hinge dragon 2 is arranged in defibrination chamber pan feeding horizontal tube 9, and the edge and the tube wall of the helical blade on it are tangent, and wing wheel 10 is directly fixed on the abrasive disk seat 6.After treating defibrination material pan feeding, screw auger 2 mainly is to be used for and will to treat that the defibrination material axially promotes charging; Wing wheel 10 mainly is to produce radial thrust by its radioactivity arcuation blade, slurry is constantly clamp-oned the mill mill separate in the gap operation of pulling an oar.Screw auger 2 and wing wheel 10 can be made into one, by the screw thread at its installed surface center and the screw rod bolted of rotary main shaft 8 terminations, by some double-screw bolts wing wheel 10 are reinforced with abrasive disk seat 6 and are installed.The slurry propulsive mechanism of the foregoing description mainly designs at the plane mill, and this propulsive mechanism also is suitable for taper rubbing disc.Among the another kind of embodiment as shown in Figure 2, what its mill adopted is taper rubbing disc, movable grinding disc 56 keys wherein are fixedly mounted on the top of rotary main shaft 8, this mill structure just can be separately by screw auger 2 as the slurry propulsive mechanism, to treat that the defibrination material clamp-ons its oblique mill and separate in the gap, because of not installing wing wheel additional, make structure more simple.Screw auger in the present technique can also adopt the screw auger 20 of cone spiral vane as shown in Figure 3 except that can adopting equidistant isodiametric helical blade, its taper blade edge and pan feeding horizontal tube inwall are tangent.This middle-density refiner is simple in structure, is easy to dismounting, and static cutting disk 4 is bolted on the cover 3 of defibrination chamber 7, cover 3 and support seam location, and feeding pipe 1 connects with cover 3 seams location and by bolting.
Middle-density refiner of the present utility model, utilize itself some structure to solve the charging problem of middle concentration slurry dexterously, unless therefore need need not especially before middle concentration slurry pulping, to install stock pump additional, both made dense pump in the needs, its power is also much smaller than the employed stock pump of existing production technology equipment.
