Description
Technical field
The invention belongs to the 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 foamed asphalt generating means is the key core place.Existing foam device is that pitch mixes in foam maker with the foaming medium, and the foaming back is assigned to each nozzle place ejection by pipe arrangement, and this mode nozzle easily stops up, and produces non-uniform phenomenon, and the sprinkling amount is difficult for regulating.On supporting application of incorporate foamed asphalt generating means and the multiple road building equipment, its complex structure, cost an arm and a leg, maintenance difficult, and be difficult to be applied on the dissimilar relevant devices, influence the popularization of foamed asphalt regeneration technology.
Summary of the invention
The technical problem of the present invention for existing in the solution known technology, and a kind of spray cavity type generating apparatus for foam asphalt is provided.
The purpose of this invention is to provide a kind of simple in structure, control is convenient, cost is low, foaming effect is good spray cavity type generating apparatus for foam asphalt.
The technical scheme that the present invention takes is:
A kind of spray cavity type generating apparatus for foam asphalt comprises nozzle, is characterized in: generating means has the asphalt foaming chamber, and (operating) water nozzle, gas jets are arranged in the asphalt foaming chamber, and (operating) water nozzle, gas jets cooperate installation, asphalt foaming chamber to be connected spray nozzle with the pitch inlet port.
The present invention can also adopt following technical measures:
Described spray cavity type generating apparatus for foam asphalt is characterized in: the asphalt foaming chamber connects fairlead, and fairlead connects the cylinder of control pitch switch, and the pitch inlet port is the open annular cover that fairlead connects.
Described spray cavity type generating apparatus for foam asphalt is characterized in: guiding interlocks dress pitch bar, and the pitch bar even is fitted together several foam chambers.
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, the spray nozzle.
Described spray cavity type generating apparatus for foam asphalt is characterized in: mechanical connection manner is a screw connection structure, is threaded exotic material fluorubber potted component is housed.
Advantage that the present invention has and good effect:
Spray cavity type generating apparatus for foam asphalt adopts brand-new technology scheme of the present invention, be connected with cylinder at the fairlead upper bolt, cylinder control hard pitch enters foam chamber, bottom in the asphalt foaming chamber is connected with (operating) water nozzle and gas jets respectively, (operating) water nozzle is connected with air compressor with the 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 the three can produce foamed asphalt, and in foam chamber, produce certain pressure, finally the spray nozzle umbrella that connects via the foam chamber bottom sprays out.The success or not of asphalt foaming or effect quality, foam device structure design are one of core technology of this system.The producing cost of relative mulseal, the major advantage of foamed asphalt technology 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 promptly pitch mixes in each nozzle end (foam chamber) with the foaming medium, sprays this foam device compact conformation, work simplification behind the foaming and intumescing.This invention can be used for the cold reclaim equiment of plantmix, also more is applicable to vehicle-mounted removable, can satisfy the requirement of all kinds of cold-mix asphalt ground surface material regeneration constructions.Greatly reduce cost, help the popularization of the cold regeneration technology of foamed asphalt.

Among the figure: 1, foam chamber, 2, (operating) water nozzle, 3, the 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, characteristics and effect, exemplify following examples now also in conjunction with the accompanying drawings, be described in detail as follows:
Embodiment
A kind of 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 control pitch switch, and the pitch inlet port is the open annular cover that fairlead connects.(operating) water nozzle 2, gas jets 7 are arranged in the asphalt foaming chamber, and (operating) water nozzle 2, gas jets 7 cooperate installation, asphalt foaming chamber to be connected spray nozzle 8 with the pitch inlet port.Employing mechanical connection manner between asphalt foaming chamber and (operating) water nozzle 2, gas jets 7, pitch inlet port, the spray nozzle 8.Mechanical connection manner is a screw connection structure.Guiding interlocks dress pitch bar 3, and pitch bar 3 even is fitted together several foam chambers.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 takes place.Pressure in the aperture of the fairlead 4 at foam chamber place, (operating) water nozzle 2, gas jets 7, pitch bar and the foam chamber, the temperature of pitch and pitch, water, compressed air three's proportioning is the effect that directly influence produces foamed asphalt, needs the control system cooperation to realize.According to the actual requirement of foamed asphalt mix, can on pitch bar 3, deploy a plurality of foam devices.
The operating principle of present embodiment:
Start foaming pitch sprinkling system, bitumenpump, foaming water pump and air compressor arrive foam chamber with 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.Become certain included angle between gas jets 7 and the foam chamber 1, help producing cyclone in foam chamber, help eruption bubble pitch, " on the spot " produces foamed asphalt like this.By actual highway section production engineering specifications, control three's proportioning guarantees foaming effect.The control system parameter is regulated the rotating speed of pump, guarantees the sprinkling amount of necessary requirement.
