Description
The utility model relates to a kind of spray-drying pelleting machine, belongs to the equipment that makes feed particlesization, especially is applicable to the granulator that medicine, food, chemical industry, light industry operation grain products are produced.
The facility for granulating of known application fluidisation---spray-drying process technology has obtained using widely in industries such as medicine, food, but existing granulator exists many problems: the accumulated powder of the auxiliary material cloth bag of the indoor employing of spray-drying causes group power big, the equipment evaporation capacity is very low, and fluidisation is bad; When needs treat liquid inventory is big, can causes serious dead bed and can't operate, simultaneously because the accumulated powder of cloth bag makes granulating rate lower.
China utility model patent CN2275480Y discloses a kind of " fluidisation---spray-drying pelleting machine ", this patent changes the auxiliary material cloth bag of spray drying chamber into tower outer whirlwind separator, atomizer is arranged on cat head central authorities, this just causes the atomizing just of liquid material promptly to be taken out of tower body, and influences effective ingredient in granulating speed and the finished product; Secondly it is delivered to the isolated powder of cyclone separator around the cat head atomizer with wind, cause secondary air and fluidized wind to collide, the sticking powder in inner wall of tower top is increased, if blow with high-temperature hot-air, then around the atomizer and inner wall of tower top produce coke powder even cause that material burns, if with the air-supply of low temperature wind, have a strong impact on the branch water evaporation of firm atomized liquid material again.
The purpose of this utility model be overcome the above-mentioned weak point of prior art and provide a kind of and be applicable to granular material and liquid material, the dead bed of nothing phenomenon, improve the liquid handling amount, reduce equipment energy consumption, spray-drying pelleting machine that the finished particle qualification rate is high.
The utility model comprises a go-cart, by support with air inlet, be contained in powder bucket, top in the go-cart and have air outlet and have the spray drying chamber of returning charge mouth with the bottom and be connected the spray drying chamber and the bracing frame of support connects and composes a fixing pyramidal structure, be provided with dispersion plate between powder bucket and the support, this dispersion plate and powder bucket are formed fluid bed, between spray drying chamber and powder bucket, be provided with pressure bladder, between powder bucket and support, be provided with pressure bladder, form fluidisation---the spray tower of a complete closed.
The air outlet on top, spray drying chamber and a top have the cyclone separator that exhaust outlet, lower end be provided with discharging opening successively and close air-valve and are connected, the returning charge mouth of bottom, spray drying chamber is connected with a stirring-cage type feeder or air blast feeding device, and the charging aperture of this stirring-cage type feeder or air blast feeding device is connected with the cyclone separator lower end.
Be provided with the adjustable atomizer seat of height and position in the bottom, spray drying chamber, this atomizer seat is provided with a stay pipe and feeds the spray drying chamber, is provided with the atomizer shower nozzle in its termination.
The secondary compressed air passage that compressed air road that the liquid material passage that the atomizer shower nozzle is made up of liquid material pipe in the stay pipe and hydrojet material mouth, compressed air hose and compressed-air atomizer are formed and secondary compressed air pipe and secondary compressed air nozzle are formed constitutes.When material viscosity is big, add and use secondary compressed air.
The go-cart of containing the powder bucket of granular material in being equipped with is pushed between spray drying chamber and the support, with pressure bladder with the gap sealing between them, spray into liquid material and compressed air realization atomization drying with twice outer atomizer shower nozzle that mixes compressed air stream, send into hot blast through the support air inlet, pass dispersion plate, under the thermal current effect, the mist material falls into fluid bed and forms fluidized state with powder, then liquid mist is changed into the granular material surface that small drop is sprayed at motion, progressively form the particle product of constantly growing up.
The utility model compared with prior art has following advantage:
1, the utility model adopts twice outer gaseous mixture streaming atomizer, its installation site is located at the bottom, spray drying chamber, can be according to the dilute phase situation adjusting position of fluidized-bed layer, can contact and adhere to powder immediately by maximum magnitude after making the atomizing of liquid material, can reduce the liquid material and be fluidized the chance that wind is taken tower body out of, accelerate granulation speed, also can avoid the sticking wall on top, spray drying chamber, the liquid handling amount is big, and atomizing effect is good.
2, the utility model will be sent into its returning charge mouth from the bottom, spray drying chamber by cyclone separator isolated frit use stirring-cage type feeder or air blast feeding device and continue to granulate, unlikely and fluidized wind collides, fluid effect is good, the sticking powder in inner wall of tower top significantly reduces, can not produce coke powder, the moisture of atomized liquid material is better evaporated, and the processing time obviously shortens, and granulating rate greatly improves.And then also reduced equipment energy consumption.
3, the utility model is all practical for granular material and liquid material granulation, and granular material then is loaded in the powder bucket, and liquid material then sprays into from shower nozzle.
The explanation of accompanying drawing drawing:
Fig. 1 is a structural representation of the present utility model.
Fig. 2 be among Fig. 1 shower nozzle C to cutaway view.
Following the utility model will describe in detail embodiment (in conjunction with the accompanying drawings).
