Description

Counterflow ebullition dryer

The utility model is a kind of drying equipment that is used for industry granular materials such as pharmacy, chemical industry, food, feed, agricultural byproducts.

At present, the drying machine that manufactures and designs both at home and abroad is of a great variety, multifarious, as band drier, vacuum drier, boiling drier, fluid bed dryer, impulse drying machine, hot-air oven etc., but these some problems of drying equipment ubiquity, system's design more complicated, be provided with some as auxiliary devices such as air blast, air-introduced machine, cyclone separator, sack cleaner, steam heater, operating desks, make the complete machine floor space big, manufacturing cost is higher, operating maintenance is difficult; These drying equipment difficult feed, heat transfer rate are slow in addition, power consumption is big, continuous operation and automaticity are low, waste energy, production efficiency is lower, yield poorly, the incompatible production in enormous quantities in enormous quantities, hygienic conditions are poor, pollution is handled bad, the dry working time is longer, and therefore develop a kind of novel adverse current boiling drier is new problem anxious to be solved both at home and abroad always.

The purpose of this utility model is exactly for a kind of structural design is provided, and systematic comparison is simple, the cancellation auxiliary device, floor space is little, cost is low, charging is easy, be suitable for batch process, automaticity height, the production efficiency height, heat transfer rate is fast, and heat exchange is abundant, uniform drying, energy savings, drying time is short, and operating maintenance is convenient, noise is low, shock insulation is good, and is pollution-free, the adverse current boiling drier that the scope of application is wide.

The purpose of this utility model is achieved in that whole device is by blower fan, little screen pack, motor, pedestal, spring, lower plugboard, material holding tray, outer shroud, vibra shoot, screen cloth, the discharging mouth, filter dictyosome, the serious offense filter screen, screw, nut, chimney fan, last plate, silk screen, trough floor, upright tube, heating tube, resistance wire, loading hopper is formed, blower fan is fixed on the pedestal, little screen pack is fixed on the material holding tray bottom on blower fan top, motor is fixed on blower fan both sides intersection and is installed in the material holding tray bottom, the spring bottom is connected with pedestal, top is connected with material holding tray, the material holding tray upper left quarter is loading hopper fixedly, lower plugboard is fixed on the material holding tray middle lower portion, material holding tray top fixed jacket cover, the fixing discharging mouth in shroud top outside, fixed grit in the discharging mouth, the dictyosome of the fixing filtration in shroud top outside, filter dictyosome flange and chimney fan flange screw, nut is fixed, plate is equipped with in the chimney fan exit, upright tube is fixed on the material holding tray, it on the vibra shoot spiral cell body, be fixed on the outer garden of upright tube, trough floor is separately fixed at the upright tube opening part outside, silk screen is fixed on the upright tube opening part outside, heating tube in the upright tube is fixed on the material holding tray, and resistance wire is installed in the heating tube.Main points of the present utility model are its structural shape and operation principle.Its operation principle and method of operating are: settle because two vibrating motors intersect, to inner rotary, settle because two vibrating motors intersect, to inner rotary, produce moment of inertia by unbalance mass; The horizontal component moment of inertia makes and is transferred plastid and does whirling vibration.The vertical component moment of inertia makes and is transferred plastid generation vertical vibration, and will being transferred plastid, resultant vibration throws forward along the vibrating transportation screw channel, so circulation, every resultant vibration once, material is just thrown forward and is jumped once in the screw channel, continuous shaking can will be transferred material and serve along screw channel, and reach the purpose of motion.Particulate material is directly gone into material holding tray by loading hopper, because the effect of vibrating motor, the vibra shoot that particulate material is installed along spiral drives in the wrong direction and up moves, the high-pressure blast that is installed on the high-head blower fan generation of bottom simultaneously enters heating tube through filter screen, resistance wire in the heating tube is with air heat, heated air rises to the top and returns out, down move along the outer wall of heating tube and the passage between the upright tube, enter upright tube simultaneously and go up the fresh air inlet of helical arrangement, enter in the end interlayer of vibra shoot, and from the upper strata high density silk screen of vibra shoot interlayer, get out, the particulate material in the vibra shoot is blown afloat, be fluidized state.Particulate material is up moved with the following boiling of the vibration limit adverse current of vibra shoot under the blowing of hot blast, and in this process, hot-air is passed to wet granular with heat, the water evaporates in it is separated, and the moisture content that evaporates is taken away, to reach the purpose of dried particles.Hot-air promptly is that thermophore is again to carry wet body, and it will pass to particle to the heat of oneself, again the vaporization moisture content of particle is taken away, and it is relevant with the temperature of self that its heat-carrying is carried wet ability, and the high more ability of temperature is big more.When hot blast and particulate material run to the top, discharge from the discharged orifice that has Screening Network with dried granules, damp-heat air is by discharging through carse, medium and small three-stage filtration net, and the smalls of the particle of carrying secretly in the air is filtered nets stifled staying, and wherein the first order and the second level are thick, middle screen pack.Because of on main frame along with the vibration and the special setting of installation site, so the particle that detention is got off can split away off voluntarily with vibrating, and self-cleaning function is arranged.Third level screen pack is very thin, and its stifled smalls that stays can regularly be opened collection.Damp-heat air is wherein just discharged outside the machine can not contain particulate material behind three-stage filtration, can adjust with the size and the dry requirement of water content the drying time of particulate material in machine, and air quantity, blast, wind-warm syndrome can be regulated by plate.

The utility model has compared with prior art been cancelled auxiliary device, floor space is little, cost is low, energy savings, efficient height, use easy to maintenancely, will be widely used in every profession and trade granular material drying.
