Environmental Protection Industrial Pork Manure Drying Equipment

Energy Saving High Humidity Material Industrial Drying Equipment?For Pork Manure

Material Description:

High humidity material generally refers to the material with the water content of 50%-80%, the common

high humidity materials include pork / chicken / cow manure, bean dregs, drug residue, cassava dregs,

lees, fructose powder, soy sauce and vinegar residue, etc., it’ll need to be dried to the safe storage

moisture-13%, if you want to make rational utilization of these materials.

The most traditional disposal way of the livestock manure is to sell as farmyard manure with the low

price and be used directly as the agricultural fertilizer, its economic value is not to fully explored and

utilized. In fact, these are the precious fodder and fertilizer resources, if it can be developed and utilized,

it will have great significance to the organic fertilizer manufacturing, to the development of planting and

breeding industry, to promote agricultural production and income, energy saving and pollution-free green

food, green agriculture development, to environmental protection and people\'s health.

Process Flow:

The dewatered material 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: The material 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 material can’t be

formed into sticky stuff under the stirring of large guide angle lifting plate. The material curtain will be

formed while the sludge is lifted up at this area, and it will cause the material 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 material can be quickly removed from

the cylinder wall by the cleaning device, and the cleaning device can also crush the materials 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. 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. There aren’t stirring plates at this area of the dryer

cylinder, and the material will be rolling to the discharging port. The material 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 material 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:

1. 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.

2. Reliable running, good stability

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

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.

3. 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 advantage
