Reference：Rotary kiln 1, cools down feed pipe 2, water inlet 21, outlet 22, outer cylinder body 23, inner barrel 24, cooling
Aquaporin 25, dividing plate 26, overhead gage 27, lower baffle plate 28, powder dust separating device 3, air exhauster 4, baling press 5.
Specific embodiment
Below in conjunction with the accompanying drawings this utility model is further illustrated.
As shown in Figure 1 and Figure 2, anhydrous iron phosphate dried bean noodles drying system of the present utility model, including rotary kiln 1, cooling feed pipe
2nd, powder dust separating device 3, air exhauster 4 and baling press 5,2 one end of the cooling feed pipe are connected with the discharging opening of rotary kiln 1,
The other end is connected with the dusty gas entrance of powder dust separating device 3, the air outlet of the air exhauster 4 and powder dust separating device 3
It is connected, the baling press 5 is connected with the powder outlet of powder dust separating device 3；
The cooling feed pipe 2 includes inner barrel 24 and outer cylinder body 23, is formed between the inner barrel 24 and outer cylinder body 23
Cooling-water duct 25,2 bottom of the cooling feed pipe are provided with water inlet 21, and cooling 2 top surface of feed pipe is provided with water outlet
Mouth 22, the water inlet 21 is connected with cooling-water duct 25 with outlet 22.
The operation principle of the system is as follows：
Raw material powder temperature after 1 drying and dehydrating of rotary kiln reaches 480 DEG C of high temperature powder and is entered by the discharging opening of rotary kiln 1
Enter to cool down in feed pipe 2, due to the effect of air exhauster 4, by the air suction cooling feed pipe 2 of a large amount of natural temperatures with high temperature
Powder is mixed, and high temperature powder is fed forward into powder dust separating device 3 with the flowing of air, dust separator by air with
Dust is separated, and clean air is extracted out from the air outlet of powder dust separating device 3 by air exhauster 4, and powder is then from dust separation
The powder outlet of device 3 enters the pack packaging of baling press 5.
Dust in the course of conveying of cooling feed pipe 2 is sufficiently mixed with the natural air of a large amount of suction, can be greatly reduced
Its temperature, while being passed through cooling water from the bottom to top in cooling tube, can reduce conveying ambient temperature, further dust is dropped
Temperature, therefore, powder can be cooled down with fast cooling under this dual-cooled effect, in the cooling feed pipe 2 for arranging appropriate length
Afterwards, the powder temperature for exporting can be made from the powder outlet of powder dust separating device 3 to reach requirement.
Powder is cooled to required temperature by cooling feed pipe 2, needs longer distance, here apart from interior, if only
Arranging a water inlet 21 can cause cooling 2 back segment temperature of feed pipe too high with outlet 22, it is impossible to reach good cooling effect
Really, for this purpose, it is preferred that, be provided with dividing plate 26 in the cooling-water duct 25, the dividing plate 26 is by cooling-water duct 25
It is divided into multiple cooling units, each cooling unit two ends to be connected to water inlet 21 and outlet 22.The setting number of dividing plate 26
Depending on amount is according to cooling water temperature change, it usually needs arrange multiple, be separated out multiple cooling units, to ensure that whole piece cooling is sent
Expects pipe 2 is respectively provided with good cooling effect.
On cooling feed pipe 2, water inlet 21 is opened in lower section, and outlet 22 is then opened in top, to ensure cooling water
Water can be full of in passage 25, and in order to prevent flow of cooling water uneven, causes pipeline hot-spot to affect cooling effect, as
Optimal way, is arranged at intervals with overhead gage 27 and lower baffle plate 28 in the cooling unit；At the top of the overhead gage 27 and outer cylinder body
23 inner wall sealings connect, the interval between 23 inwall of bottom and outer cylinder body with Cooling Water circulation；28 bottom of the lower baffle plate
It is connected with 23 inner wall sealing of outer cylinder body, there is between 23 inwall of top and outer cylinder body the interval of Cooling Water circulation.So just compel
Make cooling water flowing be bent up and down in cooling duct, fully pipeline is cooled down.
Powder dust separating device 3 is that from as the device separated in the air for transporting carrier, which specifically can be with using powder
The separation for selecting cloth bag separator etc. industrially conventional or dust arrester, but it is preferred that, the powder dust separating device 3 is adopted
Use cyclone separator.The dust removal mechanism of cyclone separator is to make dust-contained airflow rotate, by means of centrifugal force by grit from
Wall is separated and is trapped in air-flow, then makes grit fall into ash bucket by action of gravity.Which needs larger in dust removal process
Dedusting wind-force, and the air exhauster 4 for conveying power as dust be able to provide the wind-force, therefore cyclone dust extractor is defeated with air force
Send and agree with the most, be selected as powder dust separating device 3 the most appropriate.
