It is equipped with the mounting hole adaptable with the upper end shape of foaming cavity 12.
As shown in figure 8, the outside of the setting asphalt nozzle 19 of foaming cavity 12 is additionally provided with annular groove, it is arranged in annular groove
There is sealing ring.
The foam device 1 of the present embodiment is removable installed on flusher 2.As shown in figure 5, foam device 1 passes through
Stay bolt is connected on flusher 2.And flusher 2 upper surface and foaming cavity 12 between be provided with rubber pad with into
Row sealing prevents asphalt foam from leaking.
The structure of flusher 2 is described in detail below.
Flusher 2 includes the asphalt foam for receiving the output of foam device 1 and makes to spray asphalt foam.Such as Fig. 5
Shown, flusher 2 includes sprinkling cavity 21.Sprinkling cavity 21 is connected to foaming cavity 12 by asphalt foam circulation passage.
As shown in figure 5, the asphalt foam channel of the present embodiment includes bellmouth, the bigger diameter end of bellmouth is set to foam chamber
12 side of body, the miner diameter end of bellmouth are set to sprinkling 21 side of cavity.The setting of bellmouth reduces asphalt foam from foam chamber
Body 12 flow to the speed of sprinkling cavity 21, to increase foamed time of the asphalt foam in foaming cavity 12 to enable pitch
Enough sufficiently foaming are to improve the quality of asphalt foam.
As shown in figure 5, flusher 2 include sprinkling cavity 21, be set to sprinkling cavity 21 on asphalt foam nozzle 22,
For closing the plug 23 and oil cylinder 25 of sprinkling cavity 21.Foam drip can be thus achieved in up and down motion by controlling oil cylinder 25
Green injection.
Oil cylinder 25 is removably disposed relative to sprinkling cavity 21.Sealing plate is provided between oil cylinder 25 and sprinkling cavity 21
24 to prevent asphalt foam from overflowing.
As shown in Figure 3 and Figure 4, the foaming spray unit of the present embodiment includes at least two set up along asphalt delivery side
A foaming spray unit.In order to which the asphalt foam amount for spraying above-mentioned at least two foaming spray unit is essentially identical, this reality
The sectional area for applying the asphalt foam nozzle of at least two foaming spray units of example is different.
It is fixed between the asphalt foam nozzle 22 and sprinkling cavity 21 of the present embodiment by internal and external threads, therefore convenient for more
It changes.
For example, for the foaming spray unit inconsistent with the pitch amount of other foaming spray units, it can be by replacing not
The adjusting to the flow for spraying asphalt foam is realized with the asphalt foam nozzle 22 of sectional area to realize each foaming sprinkling
Unit sprays the consistent of pitch amount.
In the unshowned embodiment of other accompanying drawings, the adjustable setting that saves land of the spout of asphalt foam nozzle.
In summary, the asphalt foaming flusher of the present embodiment is poor in the individual foaming spray unit foaming effects of appearance
The case where when, can replacement foaming cavity or other components by way of be adjusted, and do not have to scrap entire pitch
Foam flusher.
