Detailed description of the invention
Elaborate to embodiments of the invention below, the present embodiment is implemented under premised on technical solution of the present invention, give detailed embodiment and concrete operating process, but protection scope of the present invention is not limited to following embodiment.
A kind of two-stage compression formula biomass granulation machine, comprise pedestal 1, motor 2, gear-box 3, die holder 4, ring mould 5 and hopper 6, described die holder 4 is fixedly connected with gear-box 3 shell, described ring mould 5 is horizontally placed on described die holder 4, compression chamber is formed in the inner chamber of ring mould 5, it is characterized in that: bottom described compression chamber, be provided with powered turntable 41, by obtaining kinetic energy with the gears meshing in gear-box 3 bottom described powered turntable 41, described rotating disk is provided with main pressure roller 71 and secondary pressure roller, gap between described main pressure roller 71 and ring mould 5 is less than the gap between described secondary pressure roller and ring mould 5.Existing granulator is for the rigors of the moisture content of material; its upper limit general will control below 15%; the highest can not more than 18%; this is because in the process of Contoured squeeze; in material, moisture can not get effective scattering and disappearing, thus cause shaping after particle due to internal steam pressure excessive and burst.This programme is by arranging pony press 72, when pressing materials, first carry out precommpression fast by pony press 72 pairs of materials, because the gap between pony press 72 and ring mould 5 is larger, in pre-compression, material can not compress into forming hole by squeezed, pre-compression is the inwall of ring mould 5 and the extruding action of pony press 72 pairs of materials mainly, the high-speed rotation of powered turntable 41 makes temperature of charge in pre-compression be warming up to more than 100 DEG C instantaneously, after pony press 72 rolls, material pressure is released, moisture in material is scattered and disappeared fast, again through the extruding of main pressure roller 71, express material is entered in forming hole, formation two-stage compression process like this, make the material of high-moisture percentage extruded again after moisture is scattered and disappeared in precommpression, reduce the requirement of granulator for raw material.
Described main pressure roller 71 has two, is symmetricly set in described compression chamber, and described pony press 72 also has two, and described main pressure roller 71 is alternately disposed in compression chamber with pony press 72, and the pressure roller diameter of described main pressure roller 71 is greater than the pressure roller diameter of described pony press 72.Symmetrically arranged main pressure roller 71 and pony press 72 contribute to ensure powered turntable 41 improve quality distribution symmetry, the shake of fuselage when running up can be effectively reduced like this, and can noise be reduced; Effect due to pony press 72 is that extruding produces high temperature; and material clamp-oned forming hole molding, granulating in the effect of main pressure roller 71; pony press 72 is less than main pressure roller 71 for the action intensity of material; so by the size of pony press 72 is reduced; more space can be vacateed for laying main pressure roller 71; each step of two-stage compression is effectively carried out, while ensureing the operating efficiency of granulator, also effectively controls cost of manufacture.
Above described powered turntable 41, be also provided with roll cover 73, described roll cover 73 is arranged on above main pressure roller 71 and pony press 72, and roll cover 73 is provided with guide frustum 8, and the lateral wall of described guide frustum 8 is provided with guide fin 81.Roll cover 73 can prevent the material of top from entering in pressure roller and damage roller bearing, material can lead the edge of compression chamber by the guide frustum 8 simultaneously arranged in roll cover 73, to lead effective constricted zone by material, the speed that material falls under gravity is very slow, rate of feeding is unable to catch up with for preventing the falling speed of material, the lateral wall of guide frustum 8 arranges guide fin 81, because whole guide frustum 8 rotates along with powered turntable 41, material in hopper 6 can extrude downwards by guide fin 81, improve the material density of effective constricted zone, thus raising process velocity, raise the efficiency.
Described guide fin 81 in the shape of a spiral.Spiral helicine guide fin 81 can bear larger lateral pressure, can effectively ensure handling safety and stable conditions.
The top planes of powered turntable 41 is provided with material copy groove 9, described material copy groove 9 head 91 sinks in powered turntable 41, its afterbody 92 floats up to powered turntable 41 top planes gradually, and the afterbody 92 of described material copy groove 9 points to the position, gap between pony press 72 and ring mould 5.During powered turntable 41 High Rotation Speed, the material of bottom can be thrown to effective constricted zone by material copy groove 9, the material density of the effective compressional zone of further increase, the material simultaneously upgraded in time on powered turntable 41, prevents bottoms material hyperabsorption moisture and is bonded on powered turntable 41.
Helical teeth pressure roller all selected by main pressure roller 71 and pony press 72.Helical teeth pressure roller can produce extra axial compression, strengthens the extruding intensification effect to material, makes granulator can process the material of high-moisture percentage.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
