Description
Technical field
The utility model relates to drying equipment technical fields, and in particular to a kind of drying device of crospovidone.
Background technique
Due to the high molecular weight and cross-linked structure structure of crospovidone, not soluble in water but chance water is introduced the water into rapidly, is promoted
So that the expansion of its network structure is generated calving disaggregation, is also widely used in the excipient of tablet.The preparation method of crospovidone needs
Will under nitrogen protection, using sodium hydroxide solution as initiator, n-vinyl pyrrolidone carries out polymerization reaction, generates crosslinking
Homopolymer crude product, then crospovidone is made through centrifuge washing, spray drying, sub-sieve, wherein drying process is essential, however
Existing spray-drying installation has the disadvantage in that
1. very little for fog-spray nozzle only one and relatively dry tower, the slurry after the atomization of ejection is unevenly distributed, easy to stick
Together, quickly, the drying time before landing is limited for sinking speed, causes drying effect bad, and finished product is in big mostly for knot
Granular, illiquidity powder causes the application of product limited；
It is easily sticked to greatly very much on dry inner wall of tower 2. the raw material just sprayed is moist, material waste is not only caused also to be difficult to clearly
Reason influences continuing to use for equipment when serious；
3. the exhaust temperature being just discharged from gas outlet is very high, it is expelled directly out, waste heat from tail gas can not be recycled, be made
At the wasting of resources.
Summary of the invention
In order to overcome drawbacks described above, the utility model provides a kind of drying device of crospovidone, including drying tower,
The dry tower bottom is provided with discharge nozzle, and the drying tower top is connected with feed pipe, atomization is provided on the feed pipe
Device, the charging tube end protrude into drying tower and are connected with shunting disk, and the shunting pan bottom is evenly equipped with multiple fog-spray nozzles；Institute
State and be provided with interlayer in dry tower side wall, the drying tower is composed of upper tower body and lower tower body, the upper tower body by up to
Lower diameter becomes larger, and the lower tower body is in inverted cone-shaped, is provided with the through-hole of multilayer straight down on the upper tower body side wall,
The inclined hole of several layers obliquely is provided on the lower tower body side wall, the through-hole and inclined hole are connected in interlayer and drying tower
Portion；Escape pipe is connected at the top of the drying tower, the drying tower side-walls are connected with blast pipe, and the blast pipe and interlayer connect
It is logical, hair dryer and air heater are provided on the blast pipe, the escape pipe is connected with heat exchanger, the heat exchanger exit
It is connect with blast pipe by pipeline.
Further, the air inlet tube end is provided with air filter.
The beneficial effects of the utility model are: the utility model practicability is high, effect is good, and material is sprayed again by shunting disk
Mist head sprays, and is evenly distributed, is not easy to bond, drying effect is good；The slurry just sprayed from fog-spray nozzle is in the inner wall close to upper tower body
When, lower section is blowed to by the hot gas that through-hole straight down sprays, can not be bonded on the inner wall of tower body, the object of lower section is blown to
Material is after hot wind is blown, and surface, which has been dried, to be not easy to be sticked on inner wall, and the inclined hole on lower tower body blows hot wind obliquely, from
And extend material fall time, it makes it dry more thorough；The tail gas of escape pipe discharge enters from pipeline again after heat exchanger
Blast pipe reenters in drying tower after heating again, and heat recovery rate is high.
