Description
Technical field
The invention belongs to road building equipment technical field, particularly relate to a kind of spray cavity type generating apparatus for foam asphalt.
Background technology
At present, the spray chamber structure of road building equipment foam asphalt generation apparatus is key core place.Existing foam device is that pitch mixes in foam maker with foaming medium, is assigned to each nozzle place sprays after foaming by pipe arrangement, and this mode nozzle easily stops up, and produces non-uniform phenomenon, and sprinkling amount is difficult for regulating.On the supporting application of integrated foam asphalt generation apparatus and multiple road building equipment, its complex structure, expensive, maintenance difficult, and be difficult to be applied on dissimilar relevant device, affect the popularization of foamed asphalt regeneration technology.
Summary of the invention
The technical problem of the present invention for existing in solution known technology, and a kind of spray cavity type generating apparatus for foam asphalt is provided.
The object of this invention is to provide a kind of simple in structure, control the spray cavity type generating apparatus for foam asphalt convenient, cost is low, foaming effect is good.
The technical scheme that the present invention takes is:
A spray cavity type generating apparatus for foam asphalt, comprises nozzle, is characterized in: generating means has asphalt foaming chamber, has (operating) water nozzle, gas jets in asphalt foaming chamber, and (operating) water nozzle, gas jets coordinate installation, asphalt foaming chamber to be connected spray nozzle with pitch inlet port.
The present invention can also adopt following technical measures:
Described spray cavity type generating apparatus for foam asphalt, is characterized in: asphalt foaming chamber connects fairlead, and fairlead connects the cylinder of controlling pitch switch, and pitch inlet port is the open annular cover that fairlead connects.
Described spray cavity type generating apparatus for foam asphalt, is characterized in: fairlead even fills pitch bar, and pitch bar connects several foam chambers to be fitted together.
Described spray cavity type generating apparatus for foam asphalt, is characterized in: the employing mechanical connection manner between asphalt foaming chamber and (operating) water nozzle, gas jets, pitch inlet port, spray nozzle.
Described spray cavity type generating apparatus for foam asphalt, is characterized in: mechanical connection manner is screw connection structure, is threaded exotic material fluorubber potted component is housed.
The advantage that the present invention has and good effect:
Spray cavity type generating apparatus for foam asphalt adopts the brand-new technical scheme of the present invention, at fairlead upper bolt, be connected with cylinder, cylinder is controlled hard pitch and is entered foam chamber, bottom in asphalt foaming chamber is connected with respectively (operating) water nozzle and gas jets, (operating) water nozzle is connected with air compressor with flow-controllable water pump respectively with gas jets, hard pitch like this, water, compressed air is in certain temperature, under the condition of pressure and proportioning, intersection three can produce foamed asphalt, and in foam chamber, produce certain pressure, finally via the spray nozzle umbrella spraying of foam chamber bottom connection, go out.The success or not of asphalt foaming or effect quality, one of core technology that foam device structure design is this system.The producing cost of relative mulseal, the major advantage of place with Foamed Asphalt is except the investment of initial foam device, the expense of other productions is extremely low.This foam device adopts foam maker and nozzle integral structure, and pitch mixes in each nozzle end (foam chamber) with foaming medium, sprays this foam device compact conformation, work simplification after foaming and intumescing.This invention can be used for the cold reclaim equiment of plantmix, is also more suitable for vehicle-mounted removable, can meet the requirement of all kinds of cold-mix asphalt ground surface material regeneration constructions.Greatly reduce cost, be conducive to the popularization of the cold regeneration technology of foamed asphalt.

In figure: 1, foam chamber, 2, (operating) water nozzle, 3, pitch bar, 4, fairlead, 5, cylinder, 6, sealing ring, 7, gas jets, 8, spray nozzle.
The specific embodiment
For further understanding summary of the invention of the present invention, Characteristic, hereby exemplify following examples also by reference to the accompanying drawings, be described in detail as follows:
Consult accompanying drawing 1.
Embodiment
A spray cavity type generating apparatus for foam asphalt, has asphalt foaming chamber 1, and asphalt foaming chamber 1 connects fairlead 4, and fairlead 4 connects the cylinder 5 of controlling pitch switch, and pitch inlet port is the open annular cover that fairlead connects.In asphalt foaming chamber, have (operating) water nozzle 2, gas jets 7, (operating) water nozzle 2, gas jets 7 coordinate installation, asphalt foaming chamber to be connected spray nozzle 8 with pitch inlet port.Employing mechanical connection manner between asphalt foaming chamber and (operating) water nozzle 2, gas jets 7, pitch inlet port, spray nozzle 8.Mechanical connection manner is screw connection structure.Fairlead even fills pitch bar 3, and pitch bar 3 connects several foam chambers to be fitted together.Pitch bar 3 and guiding exotic material viton seal ring 6.
The mounting structure that this enforcement is executed: consult schematic diagram, pitch bar 3 tight fits are connected with fairlead 4, and its fitting face place is connected with sealing ring 6, and the upper bolt of fairlead 4 connects cylinder 5, (operating) water nozzle 2, gas jets 7 are connected with the lower thread in asphalt foaming chamber 1 respectively, and nozzle inserts foam chamber.The pitch outlet of fairlead 4, (operating) water nozzle 2, gas jets 7 threes' intersection is the cavity that foamed asphalt occurs.Pressure in the aperture of the fairlead 4 at foam chamber place, (operating) water nozzle 2, gas jets 7, pitch bar and foam chamber, the temperature of pitch and pitch, water, compressed air three's proportioning is the effect that directly impact produces foamed asphalt, needs control system cooperation to realize.According to foamed asphalt mix actual requirement, can on pitch bar 3, deploy a plurality of foam devices.
The operating principle of the present embodiment:
Start foamed asphalt sprinkling system, bitumenpump, foaming water pump and air compressor arrive foam chamber by high-temperature liquid state pitch, water and compressed air delivery respectively, the water of (operating) water nozzle 2 ejections directly crosses at open annular cover place with the heated bitumen that the valve port of controlling via cylinder 5 flows out, and can produce stable foaming effect.At a certain angle between gas jets 7 and foam chamber 1, be conducive in foam chamber, produce cyclone, help spray foamed asphalt, " on the spot " produces foamed asphalt like this.By actual section production engineering specifications, the proportioning of controlling three guarantees foaming effect.Control system parameter regulates the rotating speed of pump, guarantees the sprinkling amount of necessary requirement.
