Abstract
The utility model relates to a machine, namely a biomass tooth mould decompression granulator. The biomass tooth mould decompression granulator comprises a rack (1) and extruding gears (2) which are mutually engaged, wherein each extruding gear (2) is in a barrel shape; and through holes (4) are formed between teeth of gear teeth and/or on tooth tops (8) and/or on tooth sides (9). The biomass tooth mould decompression granulator is characterized in that a plurality of decompression holes (5) are formed in tooth root (10) parts of the extruding gears (2). The biomass tooth mould decompression granulator has the beneficial effects that the tooth root parts are provided with the holes so that a space for allowing materials to pass through is increased and the materials are prevented from being overstocked; the engaging pressure of the gears is relieved and the gears work stably and are not easy to damage; the production efficiency is high, the energy consumption is small and the cost is low; and the performance of the biomass tooth mould decompression granulator is improved, and the biomass tooth mould decompression granulator has very important meanings on sufficiently utilizing biomass resources including crop straws, grass and trees and the like, saving coal power and increasing the rural income.
Description
Technical field
The utility model relates to a kind of machinery, i.e. a kind of living beings tooth mold pressing decompression granulator.
Background technology
In recent years, electrification of the countryside level significantly improves, and the biomass fuel consumptions such as stalk are die-offed.Simultaneously, along with the successful popularization of agriculture dense planting technology and the raising of grain yield, the output of agricultural crop straw also significantly improves.Agricultural crop straw traffic requirements cost, stacking needs the place, and is the main boarding carrier of disease and pest in the coming year.Therefore, many peasants have to concentrate crop straw burning in the open air, have both wasted the energy, cause again air pollution, even initiation fire and aviation accident.On the other hand, along with the quick propelling of China's process of industrialization, coal electric energy day is becoming tight.In this case, biological materials such as agricultural crop straw, vegetations, make the unit volume calorific value near the granular fuel of coal through pulverizing extruding, solved above-mentioned two kinds of contradictions.Therefore, the various places multiple biological particles facility that release one after another.At present, the biomass granulation machine on the market mostly is screw, ring mode, the type such as flat-die type powdered, and the common advantage of above-mentioned facility is that pressure is large, and the grain density of compression is high, but productivity ratio is lower, and power consumption is large, and cost is higher, is difficult to popularization and application.In order to address this problem, our company develops tooth mould granulator, namely adopts intermeshing pair roller tubular extruding gear, leaves a plurality of through holes between cog groove, gear teeth both sides and tooth top, and the biomass powder particle pushes through through hole and forms particle.Experiment shows that this granulator electricity consumption is few, and efficient is high, and cost is low, and grain density also meets the requirements, and is expected to substitute the equipment of other types., because tooth top both sides and the relative easy stacking material in tooth root place during the engagement of existing extruding gear make the engaging pressure increase of gear, strengthen transmission load and power consumption, reduce operating efficiency, improve operating cost, even cause gear shaft bending or fracture defect.
Summary of the invention
The purpose of this utility model provides between a kind of gear tooth particularly the tooth root place can not stacking material, and engaging pressure is less, stable working, not fragile, the living beings tooth mould particle pressing machine that production efficiency is high, energy consumption is little, cost is low.
Above-mentioned purpose is realized by following technical scheme: develop a kind of living beings tooth mould particle pressing machine; comprise frame and intermeshing extruding gear; the extruding gear is tubular; the between cog of its gear teeth and/or tooth top and/or flank have through hole, are characterized in: the tooth root section of said each gear teeth of extruding gear has a plurality of vents.
The corresponding through hole of two gears staggered mutually when said extruding gear was intermeshing.
The corresponding vent of two gears staggered mutually when said extruding gear was intermeshing.
The beneficial effects of the utility model are: the perforate of tooth root section; both increased the space that material passes through; avoided again overstocking of material, the engaging pressure of gear alleviates, stable working, not fragile; production efficiency is high, energy consumption is little, cost is low; improve the performance of living beings tooth mould granulator, for taking full advantage of the biomass resources such as agricultural crop straw, vegetation, saved the coal electricity; increase farmers' income, have great importance.
Description of drawings
Fig. 1 is the front view of the first embodiment;
Fig. 2 is the top view of the first embodiment;
Fig. 3 is the local enlarged front view of the parts extruding gear of the first embodiment;
Fig. 4 is the local enlarged front view of the parts extruding gear of the second embodiment.
Among the figure as seen: frame 1, the extruding gear 2, the gear teeth 3, through hole 4, vent 5, gear shaft 6, engine 7, tooth top 8, flank 9, tooth root 10, root circle 11.
The specific embodiment
The first embodiment: shown in Figure 2 such as Fig. 1; the frame 1 of this living beings tooth mould decompression granulator is equipped with a pair of intermeshing extruding gear 2 by two gear shafts 6; 2 one-tenths of gears of extruding are cylindric, reach between the gear teeth 3 of extruding gear 2 on the tooth top 8 of the gear teeth 3 respectively along a plurality of through holes 4 of radially having of gear.During work, extruding gear 2 relatively rotates under the drive of engine 7, and the engaging piece of the biomass material feeding extruding gear of pulverizing can be extruded as closely granular fuel from through hole 4.Its improvement is: the tooth root section at extruding gear 2 gear teeth 3 has a plurality of vents 5, and this vent 5 also is a kind of through hole, and material can therefrom pass through, and arrives in the cylinder of extruding gear 2, discharges from an end of cylinder again.The vent 5 that represents among the figure is an inclined hole with respect to gear diameter, and its opening is positioned at the junction surface of tooth root 10 and root circle 11, and inner port is converged mutually with the through hole that tooth top 8 is opened.This structure both had been convenient to processing, and less to the intensity effect of member, and material converges rear suffered pressure and increases, and particle is tightr.
In addition, when two extruding gears 2 were intermeshing, each corresponding through hole 4 and vent 5 staggered mutually, made the space plane of the through hole of the through hole of a gear or vent and another gear or vent relative, had further strengthened the effect of pushing.
Experiment showed, increases after the vent 5, and the tooth root place is stacking material no longer, and the fault that causes disappears substantially, and the facility working stability can be worked continuously more than 900 hours.Take the type of 1.5 tons/hour of productivity ratio as example; used motor only is 30KW; than market reaction preferably the ring mode granulator reduced on year-on-year basis 73.2%; the quality of the granular fuel of compression meets the requirements; break through the high bottleneck of stalk compressed fuel power consumption cost, deeply be subjected to sample plot peasant's favorable comment.
The second embodiment: as shown in Figure 4, the tooth root 10 of extruding gear 2 and the junction surface of root circle 11 have a plurality of vents 5, and the inner of vent 5 arrives in the gear cylinder, also can reach the purpose of avoiding the tooth root solid accumulation.
Also can see among the figure, also have a plurality of through holes 4 on flank 9, the through hole 4 of flank converges mutually with the through hole of tooth top, can cooperate vent 5, avoids the accumulation of tooth root material.
