Further, the abnormity, which is mixed, is additionally provided with hot blast flow direction disturbance mouth 8025 on leaf 802.
Structure of the invention principle is described in detail below with reference to specific attached drawing:
As shown in Figs. 1-2, in-situ heat regeneration malaxation device of the present invention includes driving platform, to mix cylinder, regenerative agent case etc. more for heating
A component, key point be the hot air circulation heating for mixing leaf with abnormity in the middle part of machine mix cylinder and top using air as carrier
Hypoxemia hot air circulating system, present device is no bitumen flue gas during the work time.
As seen in figures 3-6, the structural principle that cylinder and its top burner are mixed in heating is mainly shown, arrow direction represents in figure
The flow direction of hot wind.The burner on top is that hot wind, which enters, mixes cylinder, the work temperature of hot wind using air as carrier hot air cycling heater
Degree is 500--850 DEG C, and mixing cylinder blade has scraper structure, and the reworked material that front end heater has been heated to 120 DEG C is sharp from feed inlet
It is forced into the loose device of rake and mixes cylinder, mixed cylinder blade angle 30--60 degree and utilize the abnormity for mixing limb edge while pusher backward
Material strip is played highest point and fallen by structure, is formed material curtain, is heated hot wind sufficiently when passing through, and cylinder blade rear pusher oriented simultaneously is mixed
Function, be discharged after the heating of pavement recycling material from discharge port, hot wind after blower, there is 50%-- from the return air inlet for mixing cylinder back upper place
70% part burns away into combustion chamber, and 20%--40% is discharged after entering insulating layer from burner housing, most of thermal energy
All it is to be recycled by carrier of air, saves very much fuel, burner is low-oxygen burner, and fuel is diesel oil.
As Figure 7-8, the hot blast flow direction that the heat preservation of cylinder outer wall is mixed in heating is mainly shown, arrow direction represents hot wind in figure
Flow direction.After hot wind has heated the reworked material for mixing cylinder, remaining 20%--40% is discharged after entering insulating layer from burner housing
This partial fume, mixing cylinder two sides has insulating layer, puts after the warm layer of waste heat to idle discharge, since there are also 100- for this part hot wind waste heat
200 DEG C, this partial heat is made full use of adequately to keep the temperature the two sides for mixing cylinder, the hot air temperature after emptying is in 50--80
℃。
Fig. 9 a-9d, Figure 10-Figure 14 show the second key point of malaxation device of the present invention.It is traditional that mix cylinder to mix leaf be usually 45
The function of degree, only mix and pusher backward, and of the invention this mixes limb portion and increases an edge for abnormal shape, utilizes this side
After the reworked material scraping mixed in cylinder, recycle this side that reworked material is raised highest point, reworked material falls to form material naturally
Curtain, hot wind sufficiently can heat reworked material by material curtain, and the heat that reworked material can fully absorb hot wind completes heat exchange
Process.Fig. 9 a-9d shows the structure that abnormity of the present invention mixes leaf.Figure 10, which shows abnormity and mixes leaf, to be raised reworked material to form material curtain and fall
Under.Figure 11 shows hot wind and moves towards figure across the i.e. hot wind of material curtain.Figure 12 is that working drawing when cylinder advances is mixed in this heating.Figure 13 is to mix
The structure principle chart of cylinder interior.Figure 14, which shows hot wind arrow direction in the direction of advance for mixing waveform in cylinder, figure and represents hot wind, to be walked
To.It can be seen that this abnormity is mixed and opened a fan-shaped mouth among leaf in Fig. 9 a-9d, the function of this mouthful is disturbance hot wind
Flow direction, due to mixing leaf in work rotary course, mixing leaf installation site and mixing the fan-shaped mouth on leaf for helical arrangement is hindered
Speed of the hot wind directly from air inlet to air outlet, the present invention are exactly that the wind speed of hot wind is allowed to slow down mixing in cylinder, such benefit
The heat-exchange time for exactly increasing hot wind and reworked material heats reworked material while mix more abundant.
Figure 15 is the front elevation of complete machine of the present invention.Figure 16 is that structural schematic diagram at the feed inlet of cylinder is mixed in heating, is mainly shown
The liftable roller shutter of adjustable intake.It is provided with liftable roller shutter 17 at the feed inlet that cylinder is mixed in heating, liftable roller shutter exists
While guaranteeing charging, it is adjustable enter mix the new air capacity of cylinder interior, due to this heater outlet 20%--40% air,
These new air, nothing after low-oxygen burner is exactly the new air of this 20%--40% using supplement and has burnt must be just supplemented
Contain a large amount of bitumen flue gas while oxygen to burn again.
Figure 17 is that structural schematic diagram at the feed inlet of cylinder is mixed in heating, the active guide rake after mainly showing roller shutter.It can rise
Active guide rake 18 is provided with behind drop roller shutter 17, major function is that loose device is harrowed after heater to be heated to road surface by claw pine shape
At material ridge, material then is forced to harrow into heating to mix cylinder by active guide rake 18.
Figure 18 is the discharge outlet structural schematic diagram that cylinder is mixed in heating, and discharge hatch door 19 after discharge outlet is provided with, and is passed through
Discharging hatch door 19 can be according to load come the size of automatic regulating switch afterwards.
Figure 19 is the structural schematic diagram that the adjustment of cylinder height is mixed in heating, and one end that cylinder is mixed in heating is connected by connecting rod 20 and vehicle frame 1
It connects, the other end that cylinder is mixed in heating is connect by lift cylinder 21 with vehicle frame 1.Cylinder is mixed by the adjustable heating of control lift cylinder 21
Vertical height.
It takes or uses for reference prior art and can be realized in the part that do not addressed in aforesaid way.
Above only describes basic principle of the invention and preferred embodiments, it is noted that for the technology of this field
For personnel, without departing from the structure of the invention, several modifications and improvements can also be made, these also should be considered as this
The protection scope of invention.
