Referring to figs. 1 to 4, the present invention provides a kind of reverse-flow hot recycling drying roller 1 of Anti-adhesion type, including drying rolling
Cylinder 1, cylinder heater box 2 and high-temperature gas feeding mechanism, drying roller 1 are arranged inside cylinder heater box 2, high-temperature gas supply
Device is connected to 2 one end of cylinder heater box, and high-temperature gas feeding mechanism is to the folder formed between cylinder heater box 2 and drying roller 1
3 supplying high temperature gas of layer enter after high-temperature gas is mobile from 2 one end of cylinder heater box to the other end from 1 discharge port of drying roller
It is discharged again from the feed inlet of drying roller 1 inside drying roller 1；1 both ends of drying roller to extending outside cylinder heater box 2, to
The part of outer extension is equipped with rolling ring 4, and feed inlet one end of drying roller 1 is equipped with cabinet 5, is equipped with feed pipe 6 inside cabinet 5, into
Expects pipe 6 connect drying roller 1 feed inlet, the quantity of feed pipe 6 is either one or more, multiple purposes be for
Can be simultaneously into various materials, cabinet 5 is equipped with air outlet 7；2 bottom of cylinder heater box is equipped with odd-side 8, is equipped in odd-side 8
Space in odd-side 8 is separated into two bypass passageways 10 and a central space 11 by two partitions 9, two partitions 9, and middle part is empty
Between 11 connection interlayers 3, bypass passageways 10 by discharge port connection drying roller 1 inside, two bypass passageways 10 are separately connected height
Warm gas supply device；Primary air inlet 12 is equipped between high-temperature gas feeding mechanism and cylinder heater box 2, two bypass are logical
Road 10 and high-temperature gas feeding mechanism are all provided with an extra-air inlet 13, are mounted in primary air inlet 12 and two extra-air inlets 13
One graduating valve 14；1 outer wall of drying roller is equipped with heat monitoring system.
The present invention, other than high-temperature gas feeding mechanism is independently of drying roller 1, mountable multiple groups adjustable damper can be pressed
Interlayer 3, bypass passageways 10, drying roller 1 that hot wind multichannel enters in heater box need to be controlled, realizes 1 outside wall temperature of drying roller
Controllably；High-temperature gas feeding mechanism can be the hot-blast stove of mating multifuel firing device, be also possible to other.
Cylinder heater box 2 uses highdensity thermal insulation material, efficiently reduces heat-energy losses, and top is combined using modular
Part, can be with quick-assembling, disassembly, equipment convenient for safeguarding；Configuration is not limited to round, rectangular, polygon；
Heat monitoring system by multiple groups temperature monitor, can be multiple infrared measurement of temperature, plug in sensor to roller outside
Wall multi-point temperature measurement, while roller import hot blast temperature, drum outlet exhaust temperature are measured, the temperature of reworked material cooperates automatic control
The adjusting of system processed guarantees that outside wall temperature is correct and stablizes, and guarantee enters inside drying roller 1 from 1 discharge port of drying roller
Hot blast temperature is correct and stablizes, and guarantees that the quality of production of reworked material and production safety ensure the stabilization of various temperature；
The drum driven system of drying roller 1 can also be selected in addition to it can use original four-wheel friction driving method
Body end surface driving transmission device, office does not drive driving method in chain conveyer, gear drive and decelerating motor.
The present invention generates a large amount of high-temperature gases in production, by high-temperature gas feeding mechanism, feeds cylinder heater box 2 and dries
The interlayer 3 formed between dry drum 1；
Initial heating heating period, the control valve for increasing temperature gas supply device are opened to maximum opening, and a large amount of heat is inputted
Wind opens the air valve on primary air inlet 12 and two extra-air inlets 13, controls the air quantity of each heating zone, adjusts hot wind in interlayer 3
In interior, roller, the residence time of heating；
Hot wind enters interlayer 3 by primary air inlet 12, flows along interlayer 3, due to the limitation of interlayer 3 and the work in internal air duct
With hot wind wraps up drying roller 1, concentrates plus 1 outer wall of drying roller, barrel are rapidly heated after being heated, while hot wind flow is to out
After expecting end, entered inside drying roller 1 by primary air inlet 12 from 1 discharge port of drying roller, continues to add to inside drying roller 1
Heat；Heating process can be by monitoring temperature, the variation of temperature, 3 temperature of interlayer in grasp hot blast temperature, drying roller 1, and then controls
Volume of air supply processed；
After initial heating temperature reaches predetermined value, opens extra-air inlet 13 and increases hot wind to the volume of air supply in drying roller 1,
14 aperture of graduating valve in each air duct is gradually adjusted, while reworked material is put by feed inlet, reworked material is dried；Lead at this time
The monitoring of heat monitoring system is crossed, the hot wind intake of heater box cavity is controlled, maintains the temperature in heater box to stablize, it is ensured that peace
Full production；
When production terminates or secondary production waits, reduces the hot wind of high-temperature gas feeding mechanism for amount, pressed from both sides by control
The hot wind intake of layer 3 maintains barrel, the temperature inside drying roller 1, the heels in drying roller 1 is allowed gradually to drain, by
Can be continual and steady in the temperature of barrel, thus heels will not be bonded on barrel after reduction because of temperature fluctuation；
There are one effects for odd-side 2, and heating mainly by more 1 inner walls of drying roller of hot gas and is internally heated, when long
Between heat unavoidably will lead to drying roller 1 that metal is made it is lasting be warming up to very high temperature, will lead to internal structure and
Peripheral structure damage, can at this time close primary air inlet 12, reduce the step of heating to barrel, the bypass passageways in odd-side 2
Hot wind directly can be transported to discharge outlet by 10, be entered in roller 1 from discharge port, realize cooling.
The present invention utilizes hot blast technique, eliminates the combustion zone of old-fashioned regeneration roller, makes effective drying area of reworked material
It is elongated, reworked material is substantially prolonged in the intracorporal drying time of cylinder, improves drying efficiency；Reworked material heating avoids open fire spoke
It penetrates, has prevented ageing of asphalt, easy firing phenomenon；Barrel is in the effect of inside and outside heating simultaneously, eliminates reworked material remnants bonding
Barrel phenomenon；Driving method can be in addition to it can use original four-wheel friction driving method because of the canceling position of burner
Body end surface driving transmission device is selected, office does not drive driving method in chain conveyer, gear drive and decelerating motor；Drying roller
1 feed end uses overhead feeding pipe, shares a cabinet 5 with air outlet 7, reduces cool exterior air and enters；Roller discharge end
Using in line blanking, material mouth is the entrance of hot wind simultaneously, efficiently uses space；The present invention has prevented old-fashioned roller because building stones drop
The heels caking phenomenon that the factors such as temperature, barrel temperature fluctuation are formed, makes production efficiency, the finished product of asphalt regenerative equipment
The quality of material is improved, and is reduced equipment downtime maintenance, the cleaning work of roller coherent mass, has been saved cost, improved life
Produce efficiency.
Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention., rather than its limitations；To the greatest extent
Pipe present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that: its according to
So be possible to modify the technical solutions described in the foregoing embodiments, or to some or all of the technical features into
Row equivalent replacement；And these are modified or replaceed, various embodiments of the present invention technology that it does not separate the essence of the corresponding technical solution
