Abstract
The utility model provides an air flow type spray drying machine, comprising an upper tower body, a lower tower body, an air diffusing chamber and a nozzle. The upper tower body is arranged on the upper part of the lower tower body and connected with the lower tower body; a hot air inlet is arranged on the lower part of the lower tower body; the air diffusing chamber is arranged on the lower part of the lower tower body; the nozzle is installed on the bottom of the lower tower body and composed of a nozzle body, an air nozzle, a drainage core and a liquor nozzle; the air nozzle is installed on the nozzle body, the liquor nozzle is installed in the air nozzle, the drainage core is installed in the liquor nozzle, and the nozzle body is provided with an air inlet. The utility model makes the materials dry fast by using the air flow type nozzle, and the liquid drop can be atomized evenly in the process of drying; the drying quality of the product is good, and the product has favorable dispersancy, fluidness and dissolvability; the drying process is carried out in the airtight drying tower, avoiding public hazard, improving manufacturing environment, and being suitable for the serialization mass production.
Description
(1) technical field
The utility model relates to and is used for spray-dired equipment, belongs to the drying machine technical field.
(2) background technology
Liquid material is dried to flowable, as to have certain particle size low-density powder product with spray dryer usually.Spray-dired basic principle is that liquid material atomizing is desired granularity and size distribution, contact with high temperature unsaturation gas, drop by gas carry secretly, drying and be transported to the product gathering-device.Nozzle on the existing spray dryer at high temperature stops up easily, and is inapplicable to solution and plaster pasty materials that viscosity is high, the structure more complicated, and spray amount is little, and evenly decentralization is low.The volume of spray dryer will make droplet have the sufficiently long holdup time, even maximum droplet also can be dried to desired final moisture content, therefore the volume of spray dryer is often very big, and its material saturation is low, the power consumption height, investment is big, and sometimes because need a large amount of dry airs, thereby energy utilization rate is lower.And not really desirable at aspects such as rate of drying, product drying quality, leeway still is significantly improved.
(3) summary of the invention
The utility model provides a kind of fast drying, the measured pneumatic spray drying machine of product drying matter at the deficiencies in the prior art.
The technical solution adopted in the utility model is:
The pneumatic spray drying machine is made up of last tower body, following tower body, air compartment, nozzle, and last tower body is located at down tower body top, and both link together, and following tower body below is provided with the hot blast import; Air compartment is located at down the tower body bottom; Nozzle is installed in down the tower body bottom, is made up of nozzle body, air nozzle, drain core and liquid mouth, and air nozzle is installed on the nozzle body, and the liquid mouth is installed in the air nozzle, and the drain core is installed in the liquid mouth, and nozzle body is provided with air inlet.
Nozzle is an air-flowing type, utilize compressed-air actuated high-speed motion, with feed liquid nozzle exit meet and produce liquid film division and atomizing feed liquid speed not high, and air velocity is very high, there is quite high relative velocity in two kinds of fluids, liquid film is drawn as thread, splits into tiny droplet then, and the size of droplet depends on the viscosity of relative velocity and feed liquid, the relative velocity height, droplet is thin more, and feed liquid increases, and droplet increases.
The utility model is used air flow type jet nozzle makes dry materials rapid, and drop atomizes evenly in the dry run, and temperature is not high, and the quality of product is good, and product has good dispersiveness, flowability and dissolubility, production process simplification simultaneously, convenient operation and control.In airtight drying tower, carry out, can prevent public hazards, improve production environment, be suitable for serialization large-scale production.

Among the figure: 1, go up tower body, 2, tower body down, 3, air compartment, 4, nozzle, 5, the hot blast import, 6, air nozzle, 7, the liquid mouth, 8, the drain core, 9, nozzle body, 10 air inlets, 11, riser, 12, transverse slat
(5) specific embodiment
Fig. 1 has provided the structural representation of the utility model pneumatic spray drying machine.It is made up of basic elements of character such as last tower body 1, following tower body 2, air compartment 3, nozzle 4, hot blast imports 5.Hot blast enters air compartment 3 from hot blast import 5, and under the effect of air compartment 3, hot blast evenly enters down in the tower body 2.Nozzle 4 is installed in down on tower body 2 bottoms, and feed liquid is atomized into tiny droplet by nozzle 4, fully contacts with hot blast from air compartment 3, reaches the purpose of mass-and heat-transfer.
Fig. 2 has provided the structure of nozzle schematic diagram.Air flow type jet nozzle is the critical component of pneumatic spray drying machine, and for can make droplet even, simple in structure, production capacity is big to the requirement of nozzle, and energy consumption is low and easy and simple to handle etc.Nozzle is made up of nozzle body 9, air nozzle 6, drain core 8 and liquid mouth 7, and air nozzle 6 is installed on the nozzle body 9, and liquid mouth 7 is installed in the air nozzle 6, and drain core 8 is installed in the liquid mouth 7, and nozzle body 9 is provided with air inlet 10.The high speed Compressed Gas enters air nozzle 6, feed liquid enters liquid mouth 7 through drain core 8, the two meets at nozzle exit, because feed liquid speed is not high, and air velocity is very high, there are quite high relative velocities in two kinds of fluids, and liquid film is drawn as thread, split into tiny droplet then and produce liquid film division and atomizing.The size of droplet depends on the viscosity of relative velocity and feed liquid, and relative velocity height, droplet are thin more, and feed liquid increases, and droplet increases.Feed liquid is dispersed into droplet into 10mm-60mm by nozzle, and it has very big evaporation surface, is beneficial to reach quick-drying purpose.
Fig. 3 and Fig. 4 have provided the structure chart of air compartment.Form by multi-disc riser 11 and transverse slat 12.Its effect be with the even cloth of hot blast in drying tower.
