Description
Technical field
The utility model belongs to organic fertilizer Preparation equipment, and in particular to arrives a kind of drum-type organic fertilizer dryer.
Background technology
Currently, drying for organic fertilizer mostly uses traditional roller dryer, it is once skewed before and after the roller of dryer
State, front end connect with feeding mechanism, and rear end connects with discharging mechanism, and the inner wall of rotary drum of dryer has discontinuous material rotating plate, dry
Dry hot wind along drying machine drum axial direction and material traffic direction in fair current or adverse current input dryer, in roller by being interrupted
The material that formula material rotating plate stirs is dried, and the tail gas after material drying is by drying and being directly discharged into air after dedusting.It is this
There are four defects for dryer：First, this dryer can basically reach drying requirement to the lower organic fertilizer of water content, to containing
The higher organic fertilizer of water, drying rate and efficiency are too low, cannot meet production requirement；Drying rate and efficiency are improved,
The temperature and air quantity of hot wind, but the excessively high volatilization that can cause nitrogen in organic fertilizer of hot blast temperature can only be improved, the nitrogen of organic fertilizer is reduced
Content influences the quality of organic fertilizer；Second is that the tail gas after material drying is directly discharged into air, contained preheating cannot recycle profit
With, waste of energy, high energy consumption.
A kind of Chinese utility model " efficient low-consume organic fertilizer dryer " (Authorization Notice No. CN206094863U) discloses
A kind of efficient low-consume organic fertilizer dryer, inner wall of rotary drum have continous way helical blade；Roller axially point high temperature section and dries section,
The barrel of high temperature section and section of drying is reticular structure, and high temperature section and section of drying are respectively placed in heat preservation bellows；High temperature section keeps the temperature wind
The both sides of case connect with blast pipe and discharge pipe respectively；Section of drying keep the temperature bellows both sides respectively with section blast pipe and the air draft of drying
Pipe connects；High temperature section discharge pipe is connected by backwind tube with section blast pipe that dries.The organic fertilizer dryer is dried using high temperature section
The waste heat for the low temperature hot wind being discharged after material provides heat source for section of drying, but utilization rate of waste heat is low and only will simply arrange
The low temperature hot wind gone out, which is pooled to, dries section incubator, is radially flowed out by the roller barrel of reticular structure former with organic fertilizer
Material contact is dried.It being found after use, section effect of drying of the device is undesirable, because being packed together when organic fertilizer major part,
Waste heat wind contact area is limited, and waste heat shortage of heat itself.
Utility model content
The purpose of this utility model is that：For problem low to utilization rate of waste heat in the prior art, provide more than one kind
The high organic fertilizer dryer of efficiency of utilization.
The technical solution adopted in the utility model is as follows：
