Cover plate；The center of foaming cavity closure is provided with Stirring device, and Stirring device extend into foaming inside cavity；Foam chamber
Body closure is taper, and the tapered wall of foaming cavity closure is hollow double-decker, is foamed on the inwall of cavity closure
Some spray orifices are provided with, the half of taper is heated bitumen distributor, and second half of taper is foaming media distributor.
Further, it is provided with heated bitumen conduit on the foaming cavity closure outer wall of heated bitumen distributor side；
Foaming media conduit is provided with the foaming cavity closure outer wall of foaming media distributor side.
Further, it is provided with valve on foaming media conduit and heated bitumen conduit.
Further, it is provided with rotary driving unit on the Stirring device of the external side of foam chamber；The rotation of foaming inside cavities
Turn to be fixedly installed some rotating vanes on agitator；The termination of the Stirring device of foaming inside cavities is vertically and fixedly arranged at
Rotate the center of mixing tab.
Further, some through holes are arranged on rotation mixing tab, the edge for rotating mixing tab is not contacted with foaming cavity.
Further, it is provided with filter screen between rotation mixing tab and foaming cavity opposite side seal cover board.
Further, it is provided with foamed asphalt conduit on the opposite side seal cover board of foaming cavity.
Compared with prior art, the utility model has following technique effect：
Foam asphalt generation apparatus of the present utility model, heated bitumen and foaming media enter corresponding by respective conduit
In distributor, it is injected into by distributor in foam chamber body, Stirring device is promoted by rotary driving unit to be rotated, and is revolved
Turning the rotating vane on agitator makes into the more uniform of pitch and the foaming media stirring of foam chamber, and after making stirring
Mixture is delivered on rotation mixing tab, is sufficiently mixed again on rotation mixing tab, is eventually passed at filter screen, this multistage
Reason makes pitch expand to form blister rapidly.Because whole process can be carried out continuously, so as to ensure that the continuity of production, improve
The efficiency of foamed asphalt compound is produced, the foaming effect of pitch is also greatly improved.
