Description
Technical field
This utility model relates to molding field, is specifically related to the granulating chamber of biological granular fuel extruder.
Background technology
Extruding pelletization be former powder is prepared soft material with suitable adhesive after; put into porous annular mould (being typically orifice plate or the screen cloth with sieve aperture); it is made to discharge from the another side of porous annular mould by the mode forcing extruding, then through suitable pelletizing or the prilling process of shaping.At present, extruder is mainly made up of mair motor, reductor, granulating chamber, dust cover, material stirring disc motor, and its granulating chamber is the core position of extruder, completes raw material by granulating chamber and becomes compacting from loose state the granule of shape.
Traditional granulating chamber mainly by sealing circular casing, is positioned at and seals circular die circular casing within, connects 3 ~ 4 set pressure rollers, and the continuous rotation of pressure roller in circular die inner rotation, it is ensured that in raw material can be pressed into circular die and complete granulation；Owing to pressure roller can produce substantial amounts of frictional heat when raw material is pressed into circular die, but owing to sealing circular casing, frictional force is caused not derive in time, and then easily cause circular die and be persistently heated and deform, and the continuous rotation of pressure roller also can increase persistently being heated of circular die, the service life of shortening annular mould.
Summary of the invention
This utility model is intended to provide the granulating chamber of biological granular fuel extruder, cannot shed in time solving the heat in traditional granulating chamber, and the problem that the circular die in granulating chamber deforms owing to being persistently heated.
The granulating chamber of the biological granular fuel extruder in this programme, including circular die and with the circular casing of circular die coaxial line, described circular casing is socketed in circular die, it is characterized in that: also include power set and air-blast device, the inner rotation of described circular die connects binder cam, described power set include motor and for the live roll driving circular casing to rotate, belt it is socketed with between live roll and motor, circular casing is provided with some arc air vents, described air vent includes air inlet and air outlet, and the bore of air inlet to air outlet reduces one by one；Described air-blast device includes some high pressure gas holders, and the exit of high pressure gas holder connects to be had for some conical drum airducts of air vent air blast.
The operation principle of this programme and beneficial effect thereof:
Circular casing is offered air vent, change the sealing of tradition granulating chamber, and the air outside granulating chamber entered air vent and quickly entered in granulating chamber, further according to the second law of thermodynamics (heat can spontaneously from the high object transfer of temperature to colder object), circular die frictional heat produced with granule extruding passes to air, and air is due to heated, the temperature causing air raises, and the density of the air after temperature rising diminishes, the air that temperature is higher is caused to rise, and cause the air pressure in granulating chamber less than normal barometric pressure, and then make the air outside granulating chamber re-inject and take away frictional heat, air pressure in granulating chamber is again below normal barometric pressure subsequently, and the like, reduce the temperature of circular die；Simultaneously, circular casing rotates under the drive of live roll, accelerating extraneous air and inject the speed within granulating chamber, the bore of air vent employing cambered design, and air inlet in addition to air outlet reduces one by one, air in air vent can not only be compressed, add the kinetic energy of air self, moreover it is possible to ensure that the resistance that the air in air vent is subject to is little, and then ensure that air energy vectored injection is in circular die, improve the time of contact of air and circular die, improve heat exchanger effectiveness；And change traditional binder mode at the binder cam within circular die, changed traditional continuous binder into indirect binder, provided the one-step cooling time to circular die.
Use this patent, large quantity of air can be blasted by the air vent on circular casing, and blast air and can take away a large amount of frictional heat, it is to avoid the thermal deformation of circular die, binder cam has changed traditional continuous binder into indirect binder simultaneously, enhances the cooling effect of circular die.
Further, the air inlet outer of described air vent connects curved baffle.When circular casing rotates, increased the wind resistance area of circular casing by curved baffle, wind is inducted in air inlet, and then add the intake of air inlet.
Further, described circular die is provided with some taper perforations, and sieve aperture includes that charging aperture and discharging opening, charging aperture bore are 1.5 ~ 2 times of discharging opening bore.If charging aperture bore is less than 1.5 times of discharging opening bore, charging rate is slow, owing to the air in material can not be discharged in time, air is caused to be overstock at material internal, when granule is extruded from discharging opening, and at internal filling air easily under the self gravitation of granule, rupture, cause granule short and small；If charging aperture bore is more than 2 times of discharging opening bore, charging aperture is excessive, causes the granule in sieve aperture to be difficult to be compacted, causes granule not compact, and density is low and broken, affects granule quality；In charging aperture bore be discharging opening bore 1.5 ~ 2 times, the probability of reinforcement fracture can not only be reduced, moreover it is possible to be compacted by granule, improve grain density.
Further, the outer wall of described circular casing and the surface of live roll are equipped with burr.Increase the outer wall of circular casing and the roughness on the surface of live roll by burr, and then increase frictional force between the two, it is to avoid circular casing and live roll rotation process occur situation about skidding.
Further, described discharging opening bore is 1.2 ~ 1.5 times of air outlet bore, and is coated with screen cloth on the inwall of circular casing.If discharging opening bore is less than 1.2 times of air outlet bore, the pressure making binder cam is born from the granule of discharge outlet, make granule self with certain kinetic energy, and granule is owing to this kinetic energy is from discharging opening moment out, granule is likely to occur jumps, it is likely to cause granule to be just stuck at air outlet, causes air outlet to block；And if discharging opening bore is more than 1.2 times of air outlet bore, causing air outlet bore too small and affect intake, cause the heat of circular die to take away in time, increase the probability that circular die is damaged；And discharging opening bore is between 1.2 ~ 1.5 times of air outlet bore, can effectively avoid granule to be just stuck at air outlet, can guarantee that again the intake of air outlet；Pass through screen cloth, it is to avoid extraneous impurity flies in circular casing, also avoids air outlet to be prematured by solids.
