The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment, further illustrate the utility model, should understand the following specific embodiment only be used to the utility model is described and be not used in the restriction the utility model scope.
Extremely shown in Figure 3 like Fig. 1; The utility model discloses a kind of flat-die granulator; Comprise body, template 5 and rolling device; The driving shaft 10 that rolling device comprises pressure roller shaft 3, be connected pressure roller axle bed 9 on the pressure roller shaft 3, be installed in that at least 2 pressure rollers 1, template 5 on the pressure roller axle bed 9 is installed in the body and form the granulation chamber and be connected with pressure roller shaft 3 with the internal body space; Pressure roller 1 is a tapered roller, and the axis of tapered roller is intersected in the central point O of template 5 upper surfaces, the tangent and formation crush-zone of the upper surface of the conical surface of tapered roller and template 5.The disclosed flat-die granulator of the utility model drives the roll mode of extruding of tapered roller and carries out production operation through adopting the axis tapered roller with the template circle centre position that crosses, adopting simultaneously; Avoided the sliding friction between roller and the template upper surface effectively; Reduced roller that sliding friction causes and the frictional dissipation between the template effectively, reduced the wear rate of equipment, simultaneously owing to only have a friction between rolling friction and material and the equipment between roller and the template; And there is not the sliding friction between roller and the template; Reduce the power consumption in the production of equipment effectively, reduced production cost simultaneously, improved production efficiency.
As a kind of preferred, tapered roller is 2-16.This improvement is through the quantity of the tapered roller in the control flat-die granulator; Make full use of flat-die granulator power-equipment and granulation cavity space, and effectively the cost of control appliance the time, improving the production efficiency of flat-die granulator; Reduce production cost, realized the efficient output of unit cost.
As a kind of preferred, the inwall in the outer edge of crush-zone and granulation chamber bottom is tangent on the tapered roller.The extruding dead angle has been eliminated in this improvement, has avoided being detained in the equipment appearance of material, has reduced maintenance cost; Improved the efficient of producing; Increase the granulation output of granulator effectively, made granulation chamber wall not be required to be the waist drum type simultaneously, thereby reduced the production difficulty of granulator.
4 pressure roller shaft 3 are installed on the pressure roller axle bed 9; Its axes intersect and O point, O point are the central point of template 5 upper surfaces simultaneously, adopt the mode of centre-driven; Avoided tapered roller and template 5 upper surface generation sliding frictions effectively, improved production efficiency and reduced energy consumption and capacity loss; Pressure roller axle bed 9 is installed on the pressure roller shaft 3; Bearing A2, bearing B7, sealing device 8, end cap 4 etc. are housed on the pressure roller shaft.The material that granulation chamber wall 6, pressure roller 1,9 fillings of pressure roller axle bed remain to be granulated during production, driving shaft 10 rotates through flat key 11 drive pressure roll shaft seats 9, pressure roller shaft 3, and under the frictional resistance effect of pressure roller 1 and storeroom, pressure roller 1 is around pressure roller shaft 3 rotations.Because pressure roller 1 is taper; Pressure roller 1 is tangent with template 5; And the axis of pressure roller 1 all through the center O point of template 5 upper surfaces, so pressure roller only bears rolling frictional resistance, no longer bears sliding-frictional resistance; Power consumption is greatly reduced, and can reach 150% ~ 200% of cylinder roller structure the service life of pressure roller, template.The thorough elimination of sliding friction also makes the temperature rise that is transmitted on the bearing reduce greatly, has improved the service life of bearing.
Because the axis of pressure roller is the center O point through the template upper surface all, and pressure roller is taper, and pressure roller and template are tangent; So can make the length of pressure roller reach maximum; Make full use of the space, the outward flange in extruding granulation zone can expand the edge of granulation chamber wall to, compares the cylinder roller structure; Perforated area increases more than 30%, makes production capacity increase more than 30%.
In this programme, can make the specification of bearing at inner diameter D1 and this place of pressure roller constant; It is maximum that outer end diameter D2 then can reach; Reach existing more than 1.5 times of D1 (being D2:D1 >=1.5), improved the force-bearing situation of tapered roller effectively, improve tapered roller in the granulation chamber stress area with granulation cavity template 5; Improved extruder grain area and production output effectively, thereby the bearing capacity of bearing, force-bearing situation are taken on a new look greatly.Because the axis of pressure roller all through the center O point of template upper surface, also makes average extruding angle, crush-zone reach maximum, has improved granulation ability and production capacity greatly.
The disclosed technological means of the present invention program is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme of being made up of above technical characterictic combination in any.
