Description
Technical field
The utility model relates to drying device field, is specially the spray dryer of the antiseized wall of efficient energy-saving.
Background technology
Develop rapidly along with China's economy is sent out, all trades and professions need rare material kind of dry process and quantity to get more and more, such as Chinese medicine, jujube powder, honey etc.Spray dryer be a kind of by the liquid materials such as biology, medicine, food by atomization add the equipment for drying being thermally processed into powder material, spray drying system mainly comprises sprayer and drying tower, sprayer has air-flowing type, pressure type and centrifugal, and drying tower part occurs that conical bottom adds agitating device at present.It mainly utilizes different atomizers that solution, emulsion, suspension or the plaster material containing moisture are sprayed into tiny drop in hot blast, in droplets fall process, moisture is powdered or granular product by evaporating, thus in single operation, complete spraying and dry two kinds of techniques simultaneously.
The spray drying device that tradition is single, only be provided with the drive nozzle of feed liquid pipe and atomization in drying tower, drying tower cylindrical shell is longer, and droplet particle is close to the descending at slow speed of automatic falling bodies in drying tower, the powders a large amount of when centrifugal spray drying is on the inclined-plane of spray tower, rapid zoom caking, namely have impact on product quality, very big by loss, during real work, produce and glue wall to just there will be powder when second and third day, progressively increase, finally cannot continue to produce.
Especially, for Chinese medicinal powder, existing centrifugal spray drying room is because be directly be sprayed onto in hothouse at a high speed by liquid Chinese medical concrete material, after long use, dried Chinese medicine dry extract is easily assembled and is bonded on the inwall of hothouse, make troubles not only to the cleaning of dry locular wall, also result in Effective Component of Chinese Medicine content loss simultaneously.
Wall sticking phenomenon is the outstanding problem hindering centrifugal spray dryer normal operating, and the spray-drying process of solid pharmaceutical preparation (particularly Chinese medicine) is particularly evident.Material glues wall and operates not only bad for collection, and along with the prolongation of time, responsive sticky wall material can go bad and become defective material.Wall sticking phenomenon is the major issue that spray-dired design must be considered, because: the material 1. after sticky wall, owing to resting on inwall for a long time, is likely burnt or is gone bad, being affected product quality; 2. the material after sticky wall, caking falls into the operation going out product at the bottom of the product middle finger tower at the end often, makes product sometimes can not reach the moisture content of regulation; 3. because wall material caking falls into product, some product is made to have to increase crushing process, to reach certain fineness.4. many spray drying devices, in order to remove sticky wall material, midway of having to stops spraying, and this just shortens spray-dired operational use time.Therefore be necessary to design a kind of centrifugal spray dryer, reduce material and glue wall degree, be convenient to strike off sticky wall material in time.
Summary of the invention
It is good that the purpose of this utility model is to provide a kind of drying effect, and receive powder rate high, it is few that material glues wall, not easily produces coking denaturalization phenomenon, easily clean, the measured antiseized wall spray dryer of dried material matter.
The utility model spray dryer, comprise drying tower 1, three fluid-type nozzles 2, back-shaped groove 3, porous plate 4, cyclone separator 5, mechanical agitator 8, is characterized in that, described drying tower 1 top becomes cylindric, bottom becomes inverted cone-shaped, cylindrical portion draw ratio is 4: 1-3: 1, and the cone angle alpha that inverted cone-shaped contacts with cylindrical portion is 70-75 degree, and porous plate 4 is positioned at inverted cone-shaped part, porous plate 4 is 60-70 degree with the cone angle beta of cylindrical base, the cylindrical wall of drying tower 1 has some reversion grooves.
Further, spray dryer of the present utility model has electric heater 6, blower fan 7, and blower fan 7 and electric heater 6 are connected to the inverted cone-shaped part of drying tower 1 by pipeline.
Further, spray dryer of the present utility model has pay-off, and pay-off connects three fluid-type nozzles 2.
Further, the drying tower 1 of spray dryer of the present utility model has refrigerating device inside, and cooling device comprises the cold wind chuck being arranged on drying tower 1 inwall and top, and is arranged on the cooling blower that drying tower 1 lower outside is communicated with cold wind chuck.
Further, spray dryer of the present utility model comprises blow device, and blow device comprises the scavenging conduit being arranged on drying tower 1 inside and the purging motor being arranged on drying tower 1 bottom outside, and scavenging conduit is connected by pipeline with purging motor.
Further, spray dryer of the present utility model comprises two cyclone dust collectors set gradually, and is separately positioned on the Blowing stopper bottom cyclone dust collectors; Cyclone dust collectors are communicated with drying tower successively by pipeline.
Further, the back-shaped groove on the cylindrical wall of drying tower 1 can replace with irregular groove or deep-slotted chip breaker.
The utility model medicine extract spray dryer, has following beneficial effect:
1) by having installed porous plate in the bottom of drying tower, the effect of distributing gas is mainly played.By the cone angle of selection inverted cone part and the cone angle of porous plate and bottom of cylinder, ensure that hot blast is uniformly across distribution grid, dried material would not be attached on porous plate, effectively can avoid absorption powder.
2) by arranging the cold wind chuck of integration at the inwall of drying tower and top, the cooling blower be communicated with cold wind chuck has been installed simultaneously, finally effectively can solve and grow due to material time of staying on wall and produce the rotten phenomenon of material coking, do not affect the quality of dry rear material, reach desirable drying effect, dry speed can be improved simultaneously and receive powder rate.
3) adopt three fluid-type nozzles to replace two traditional fluid-type nozzles, and by improving feed temperature to reduce its viscosity, to increase the means raising atomizing effects such as gas liquid ratio, reach the object alleviating sticky wall.
4) by increasing back-shaped groove or irregular groove, deep-slotted chip breaker on the cylindrical wall of drying tower, back-shaped groove or irregular groove, deep-slotted chip breaker go out to form stronger whirlwind at notch due to its structure, effectively avoid the adhesion of material.
