Abstract
The utility model discloses a foamed asphalt generation device which comprises a shell and a foaming chamber arranged in the shell, wherein a threaded hole I is formed at the top end of the shell; a pipeline for the asphalt to flow is mounted on the threaded hole I; the foaming chamber is positioned below the threaded hole I; an asphalt nozzle for spraying asphalt to the foaming chamber is mounted on the pipeline; a water spray hole at a 85-degree angle with the horizontal plane is formed on one side of the shell; an air spray hole at a 95-degree angle with the horizontal plane is formed on the other side of the shell; a threaded hole II is formed below the foaming chamber; a bottom plate is fixedly mounted at the bottom end of the foaming chamber through a hollow nut meshed with the threaded hole II; an eccentric hole for discharging the foamed asphalt is formed in the bottom plate; and a splash-proof cover for preventing the asphalt from splashing is arranged below the bottom plate. With simple structure and strong practicability, the device disclosed by the utility model uniformly mixes the asphalt, water and compressed air by changing the spray angles of the water and compressed air, thereby improving the asphalt foaming efficiency and having broad application prospects.
Description
Technical field
The utility model relates to a kind of pitch generating unit, especially relates to a kind of foam asphalt generation apparatus.
Background technology
Generally, by more than asphalt heating to 140 ℃, then in special asphalt foaming apparatus, heated bitumen contact with a small amount of cold water mix, carry out thermal exchange, make pitch cooling, and pitch can produce trickle foam in process of cooling, make the pitch expansion; Pitch is when foamed state, volume can be expanded to original several times, reduced viscosity, but can only maintain the several seconds, and in existing asphalt foaming apparatus, not having to consider affects from changing physical structure the state that heated bitumen sprays, and then affects heated bitumen and water collision process and transformation curve, thereby affects the characteristic of foam asphalt.
The utility model content
The utility model is for deficiency of the prior art, a kind of foam asphalt generation apparatus is provided, this device causes the variation of the degree of heated bitumen and cold water mix by changing water and compressed-air actuated spray angle, pitch, water and pressurized air are mixed more uniformly, thereby reach the effect of improving the asphalt foaming characteristic.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of foam asphalt generation apparatus, comprise housing and be arranged on the foaming chamber in housing, the top of described housing offers threaded hole one, described threaded hole one bottom centre place offers through hole, on described threaded hole one, the pipeline mobile for pitch is installed, described foaming chamber is positioned at the below of described threaded hole one, on described pipeline, be equipped with for the asphalt nozzle to described foaming chamber air blown asphalt, it is characterized in that: a side of described housing offers horizontal by 85 ° of angles and the spout hole for spraying water in described foaming chamber, the opposite side side of described housing offers horizontal by 95 ° of angles and for the gas orifice of jet compression air in described foaming chamber, the below of described foaming chamber offers tapped through hole two, described foaming chamber bottom is installed with base plate by the hollow nut be meshed with described tapped through hole two, on described base plate, offer for discharging the eccentric orfice of foam asphalt, the below of described base plate is provided with the splash guard for preventing that pitch from splashing.
Above-mentioned a kind of foam asphalt generation apparatus is characterized in that: described foaming chamber is ampuliform.
Above-mentioned a kind of foam asphalt generation apparatus is characterized in that: the position symmetry of described spout hole and gas orifice.

Embodiment
A kind of foam asphalt generation apparatus as shown in Figure 1, comprise housing 10 and the foaming chamber 2 that is arranged on housing interior 10, the top of described housing 10 offers threaded hole one, described threaded hole one bottom centre place offers through hole, on described threaded hole one, the pipeline mobile for pitch 1 is installed, described foaming chamber 2 is positioned at the below of described threaded hole one, on described pipeline 1, be equipped with for the asphalt nozzle 9 to described foaming chamber 2 air blown asphalts, one side of described housing 10 offers horizontal by 85 ° of angles and for the spout hole 3 to described foaming chamber 2 interior water sprays, the opposite side side of described housing 10 offers horizontal by 95 ° of angles and for the gas orifice 4 to the interior jet compression air of described foaming chamber 2, the below of described foaming chamber 2 offers tapped through hole two, described foaming chamber 2 bottoms are installed with base plate 5 by the hollow nut 6 be meshed with described tapped through hole two, offer the eccentric orfice 7 for discharging foam asphalt on described base plate 5, the below of described base plate 5 is provided with the splash guard 8 for preventing that pitch from splashing.
As shown in Figure 1, described foaming chamber 2 is ampuliform.
As shown in Figure 1, the position symmetry of described spout hole 3 and gas orifice 4.
As shown in Figure 1, described eccentric orfice 7 is corresponding with the hollow position of hollow nut 6.
Principle of work of the present utility model is: pitch enters in foaming chamber 2 by pipeline 1 and asphalt nozzle 9, injection water sprays in foaming chamber 5 by spout hole 8, pressurized air sprays in foaming chamber 5 by gas orifice 9, because described spout hole 8 and gas orifice 9 and horizontal plane all are 85 ° of angles, pitch, water and air can full and uniformly be mixed, due to the temperature of heated bitumen at 150-180 ℃, heated bitumen and water surface generation thermal exchange, simultaneously, the pitch volume expands rapidly, foaming chamber 2 internal pressures increase, and foam asphalt is by eccentric orfice 7 ejections.
The above; it is only preferred embodiment of the present utility model; not the utility model is imposed any restrictions; every any simple modification, change and equivalent structure transformation of above embodiment being done according to the utility model technical spirit, all still belong in the protection domain of technical solutions of the utility model.
