Description
Technical field
The utility model belongs to the mechanical equipment of ceramic industry field, particularly, relates to a kind of spray dryer.
Background technology
Spray-drying is that liquid stoste is atomized; Warp and hot blast exchange dry and the program formation powder granular products; Its stoste mat high speed rotating plate or pressure nozzle atomizing and getting in the thermal current in spray dryer; This drop moisture content in hot blast evaporates rapidly, stays dry solid powder/particle, again by separating in the air-flow; Because its short drying time, flexible operation and be easy to automation, so extensively apply in the ceramic industry.
Chinese patent CN200820041974.4 discloses a kind of a kind of spray dryer that discloses, and comprises air compressor machine, cyclone separator, peristaltic pump, blower fan, heater, hothouse and atomizer.The shortcoming of this spray dryer is: relatively poor, the inefficiency of atomizing effect.
The utility model content
The purpose of the utility model is the deficiency to prior art, provides that a kind of atomizing effect is good, the spray dryer of high efficiency.
For achieving the above object, the utility model adopts following technical scheme to realize:
Spray dryer comprises drying tower, and said drying tower top is provided with air-supply arrangement; Said drying tower one side is provided with pay-off; Said drying tower opposite side is provided with the laying dust device, and said drying tower bottom is provided with material collecting device, it is characterized in that; Said pay-off comprises mud agitator, the delivery pump that is connected with the mud agitator and the feed pipe that is positioned at drying tower; This feed pipe is connected with said delivery pump through pipeline, and said feed pipe is a ring pipe, and this its circumferencial direction of feed pipe upper edge is provided with some shower nozzles.
Further, said air-supply arrangement comprises air-heater and ajutage.
Further, said laying dust device comprises discharge pipe and whirlwind laying dust device.
Further, said material collecting device involving vibrations sieve.
The beneficial effect of the utility model is: through annular feed pipe and the some shower nozzles on it are set, improved atomizing effect and operating efficiency.
Description of drawings
Fig. 1 is the structural representation of the said spray dryer of the utility model;
Fig. 2 is the pay-off vertical view of the said spray dryer of the utility model.
The specific embodiment
For structure, characteristic and effect thereof to the utility model, can have and further understand and be familiar with, lift a preferred embodiment at present, and be described with reference to the accompanying drawings as follows:
As shown in Figure 1, it is the described spray dryer of the utility model, comprises drying tower 1; Drying tower top 1 is provided with ajutage 6 and air-heater 5; Drying tower 1 one sides are provided with pay-off, and drying tower 1 opposite side is provided with the laying dust device, and drying tower 1 bottom is provided with material collecting device.
Shown in Fig. 1-2, pay-off comprises mud agitator 7, the delivery pump 8 that is connected with the mud agitator and the feed pipe 9 that is positioned at drying tower, and this feed pipe 9 is connected with delivery pump 8 through pipeline.As shown in Figure 2, feed pipe 9 is a ring pipe, and its circumferencial direction of feed pipe 9 upper edges is provided with some shower nozzles 10.
As shown in Figure 1, the laying dust device comprises discharge pipe 3 and whirlwind laying dust device 2.Said material collecting device involving vibrations sieve 11 and conveyer belt (not shown).
During use, need dry raw material promptly in this mud agitator 7, to stir the back, behind delivery pump 8, send into feed pipe, through shower nozzle 10 ejections by the pipeline guiding.Mud after being dried powders; This powder is discharged drying tower 1 and is fallen in the vibratory sieve 11 of below; Powder behind the sieve is delivered to power collecting bucket or suitable position by conveyer belt, and the part waste gas in the tower and aqueous vapor be then by deriving drying towers 1 via discharge pipe 3, and by cyclone 2 collections; All the other then by the sucking-off of primary air fan (not shown), are discharged through exhaust chimney.
The above is merely the preferred embodiment of the utility model; It is not the practical range that limits the utility model with this; Allly be familiar with this operator; The principle and the technical characterictic of utilization the utility model, various changes and the decoration done all should be covered by within the protection category that these claims define.
