Convenient Operation Industrial Drying Equipment For Drying Cow Manure

Process Flow

The cow manure will be transported to feeding head of the dryer through the screw conveyor after

scattering, and then it will be sent into the inside of the dryer through the unpowered spiral sealing

feeder (the patent technology of our company), and going through several following working areas after

getting into the dryer:

1. Material leading-in area

The cow manure will come into contact with the high temperature negative pressure air after getting into

this area and plenty of water will be rapidly evaporated, and the cow manure can’t be formed into sticky

stuff under the stirring of large guide angle lifting plate.

2. Cleaning area

The cow manure curtain will be formed while the sludge is lifted up at this area, and it will cause the cow

manure stick on the cylinder wall while it’s falling down, and the cleaning device is installed at this area

(Lifting style stirring plate, X type second time stirring plate, impacting chain, impacting plate), the cow

manure can be quickly removed from the cylinder wall by the cleaning device, and the cleaning device

can also crush the cow manures which are bonded together, so as to increase the heat exchange area,

increase the time of heat exchange, avoid the generation of wind tunnel phenomenon, improve the drying

rate.

3. Inclined lifting plate area

This area is the low temperature drying area, the slime of this area is at the low moisture and loose

state, and there is no adhesion phenomenon at this area, the finished products reach the moisture

requirements after the heat exchange, and then enter the final discharge area.

4. Discharging area

There aren’t stirring plates at this area of the dryer cylinder, and the cow manure will be rolling to the

discharging port. The cow manure gradually becomes loose after drying, and discharged from the

discharging end, and then sent to the designated position by the conveying device, and the fine dust

drawn out along with the tail gas is collected by the dust collector. Hot air enters into the drying

machine from the feeding end, and the temperature is gradually reduced at the same time of cow

manure convection heat transfer, and the water steam taken out under the suction of induced draft fan,

and then emitted into the air after processing.

System Advantages

High thermal efficiency, low drying cost

New internal structure, and strengthen the cleaning of dispersed material and heat conduction, eliminate

the sticking phenomenon of the barrel body’s inner wall, it’s more adaptable to the material moisture

and stickiness, the heat exchanging area and the drying efficiency are increased. The operating

parameters can be changed according to different materials, and the heat exchange of the material in

the dryer is more fully.

Reliable running, good stability

The new type of feeding and discharging device, put an end to the phenomenon of the plug in f

feeding, incontinuity, nonuniform and material return. The "aligning roller device” is adopted by the dryer,

which makes the tug and rolling ring always do the linear contact, and it greatly reduces the abrasion

and power consumption. The “zero horizontal thrust” of the dryer is realized, which greatly reduces the

abrasion of the gear wheel and supporting wheel, the cylinder operation is more stable and reliable.

Wide range of heat source using, environmental protection and non-pollution

The coal, oil, natural gas, liquefied petroleum gas can be used as fuel. It’s determined according to

material requirements and local natural advantages, to improve production efficiency and economic

benefits.
