Description

Concave-convex type patterned roll is to crowded compression forming particle mechanism
Technical field
The utility model relates to concave-convex type patterned roll to crowded compression forming particle mechanism, belongs to technical field of mechanical equipment.
Background technology
Grain forming mainly refers to various biomass grain forming, as pellet, and biomass granule fuel etc.
Present stage, China's biological substance shaped granule was mainly based on flat-die and ring mould two kinds of modes, within nearly 2 years, had mechanical stamping molding mode and arc-shaped gear rod to crowded mode.Now several extruded mode is described below:
A, flat-die and ring mould are a reason in fact, and just template form is different, and discharging direction is different.As depicted in figs. 1 and 2:
Flat-die extruding realizes template and pressure roller by the horizontal shuttering band dynamic pressure roller of rotation to do rightabout and rotate, and the friction and Extrusion produced by the opposite direction rotating of template and pressure roller, is forced through nib and extrudes and be shaped to required particle by biomass material.
The principle of ring mould extruding is about the same with flat-die, is all that biomass material is forced through nib and extrudes and become required particle by the friction and Extrusion power that produces of relative motion between master plate and extruding rod.
B, shaping about mechanical stamping, actual is that raw material is extruded by the powerful extruding force produced by hydraulic machinery from nib.
C, extruded about arc-shaped gear, the extruding force formed when being in fact exactly and utilizing between the hollow wheel gears of two occlusions mutually running relatively, makes raw material realize grain forming by the aperture bottom roller seating space.
The problem to be solved that prior art exists, defect or deficiency:
1, about defect and the deficiency of category-A molding mode: this kind of molding mode only adapts to fine grained and pulverous biomass material, as sawdust class, stalk biomass raw material can not be adapted to.Because stalk biomass raw material after crushed, its physical behavior is not powder or fine grained completely, and mainly elongated strip-shaped fibrous, and this elongated strip-shaped fibrous can be interweaved into cotton-shaped or netted, this cotton-shaped or netted raw material is in opposing compression, extrude easily via nib unlike packing material, but the wadding block be squeezed into as cotton-wool, i.e. fibre agglomerates, this caking place mat has hidden nib and has resulted in blockage in template, so, there is the defect of adaptability to raw material difference in this molding mode, shaping individual organisms raw material that can only be limited, as sawdust, rice bran etc. after pulverizing.Here it is, and a large amount of agricultural crop straw all can not be compressed into the technical reason of biological particles so far.
2, about defect and the deficiency of category-B molding mode: this kind of molding mode seems to improve the adaptability of raw material, but carry out because blanking and extruding are interrupted, can not continuous print and uniform discharging, and compact density is on the low side, be difficult to shaping granule simultaneously, in addition, owing to setting up hydraulic servo, make former bulky, mechanism is complicated, and power configuration is high, the defect of equipment investment large (easily one, hundreds of thousands unit/cover), be not easy to promote in vast rural area, be difficult in mountain area especially be suitable for.
3, the deficiency of two class molding modes above is substantially compensate for about C class molding mode, improve the adaptability of raw material, substantially nib clogging has been stopped, the similar gear of its mould roller, its kind of drive is that the friction that initiatively discaling roll produces after filling by raw material between two rollers drives driven tooth roller to do opposite direction rotating, and intersects by the mould tooth of projection and raw material is extruded by the nib of gullet base to squeezing and realize grain forming.This fashion of extrusion, is in fact exactly utilize two intermeshing gear mesh to squeeze the extruding force of generation, makes raw material extrude by radial compression and by the circular hole of bottom land at teeth groove and be able to shaping.
But there is following major defect and deficiency in this design:
One is because in fact mould roller is not the fit system of gear as gear, there is larger interval (very close to each other just raw material can not be contained) therebetween, this just causes device start idling periods (must drop into raw material again by first starting device, otherwise machine cannot start or there is the infringement of paired reductor and motor because excess load starts).The transmission of two roller between cog can because hard collision make mould roller be subject to major injury even its reaction force can bring disaster to the safety of reductor.
Two is moduluses that this mentality of designing inevitable choice is larger, just may design corresponding forming hole at mould between cog, and general knowledge tells us, modulus is larger, and mould tooth is also larger, mould tooth is larger, its polygon effect can produce compound frictional resistance relative to raw material, thus can offset part torsion and power, which increases motor load, in order to supplement this part power consumption, just only has increase power of motor.
Three is sizes that this mentality of designing limits shaped granule, and that namely particle cannot be done is larger.This defect is that the market popularization value of this design is subject to serious restriction.
Four is that this design is in operation once run into power failure or unexpected block stock, will be stuck, and mould roller is once be stuck, and just can only carry out manual dredging after removing solution machine.
Five is that this design must cause lacking necessary processing spacing between adjacent nib, make nib opening tightly connected, its consequence shows as in heat treatment process, very easily produce stress concentration phenomenon and ftracture, also the machinery having a strong impact on nib because hole partition is too thin is slight, very easily damages under the effect of powerful extrusion friction.
