Description

It is layered hot milling equipment and the complete unit of the compound in-situ heat regeneration of hot wind and microwave

Technical field

The utility model belongs to road maintenance equipment technical field, and in particular to a kind of hot milling equipment of layering and hot wind are micro- The complete unit of the compound in-situ heat regeneration of wave.

Background technique

The huge maintenance work amount of Trunk highway highway especially highway, the maintenance project quality of high standard and super large Maintenance work environment under traffic conditions promotes us to seek a kind of new maintenance method --- in-situ heat regeneration, is a kind of Using dedicated On-site heat recycling equipment, bituminous pavement is heated, milling, then mix it is certain newly gather materials, new pitch, Regenerative agent etc. such as is mixed and stirred, is paved, being rolled at the processes, disposable to realize to the old asphalt pavement within the scope of the certain depth of surface again Raw technology.

Existing hot reproducer on the spot is primarily present following several respects defect both at home and abroad at present:

(1) road surface is burned, vegetation deterioration, environmental pollution.Road-surface heating machine mostly uses combustion oil/gas open firing, combustion gas red Outside line heating or extensive style high-power diesel Cycling hot-blast heating mode, bituminous pavement heating temperature are not easy to accurately control, Yi Zao At the aging of bituminous pavement, coking, the pavement performance decline on road surface after regeneration；The construction high warm flue gas in periphery easily leads to greening Band, trees it is burned, and with a large amount of toxic blue smoke, pollute environment；

(2) depth disease cannot be handled, construction technology bad adaptability.Hot reproducer on the spot takes one currently on the market Secondary property heat penetration is confined to 30mm~40mm depth more, causes to regenerate finite thickness, deep layer disease cannot be handled well, work Condition bad adaptability；And from construction technology, it is only able to achieve filling remixing regeneration technology at present and remixing overlays technique, can not Realize upper layer and middle surface layer in-situ heat regeneration simultaneously, and remixing overlay technique remixing process do not add it is a certain proportion of New asphalt, and pave to form regeneration zone by remixing after suitable regenerative agent is added, then overlayed on regeneration zone Certain thickness completely new asphalt, and real meaning bilayer is not implemented and paves.

(3) interlayer temperature gradient is big, aggregate destructible when milling, and it is low to form reworked material temperature, influences reproduction quality.According to system Meter, the asphalt material temperature of bituminous pavement top 10mm~20mm thickness is excessively high (up to 240 DEG C), but the drip at the 30mm~50mm of lower part Cobalt blue pigment temperature but only has 70 DEG C~80 DEG C, and interlayer temperature gradient is big, and heating is uneven；And since near-bottom temperature is relatively low, easily cause Destruction (grey material occur) phenomenon of grading of aggregates in milling process asphalt material forms only 120 DEG C or so of reworked material integrated temperature, Direct paving material is relatively low, influences reproduction quality；Take infrared heating or Hot-blast Heating to the secondary temperature raising of reworked material, heating temperature Degree should not be controlled accurately, easily caused the secondary aging of reworked material, influenced reproduction quality.

(4) high temperature road-surface heating and hot milling link flue gas, dust leakage amount are big, pollute environment.In the market again with regard to underground heat Life group lacks the recovery processing measure of high temperature road-surface heating and hot milling link flue gas, dust, and discharge is not up to standard, is unable to satisfy National related environmentally friendly provisions of laws and regulations.

(5) virgin material addition is difficult, and thermal loss is big.Remixing regenerating device frequent intermittent operation, influences reproduction quality.It is new at present The addition of asphalt mostly uses transhipment dumper to complete, and can hold together the material of 200mm~300mm thickness after road-surface heating milling Heap, before transporting dumper filling, more road-surface heating machines and heating milling machine need to move forward 20m~30m, then transport self-unloading For vehicle again across thick material heap, the charging in material heap of riding causes remixing regenerating device frequently to stop into the hopper of remixing regenerating device Only operation, thick material heap is driven out to after charging, and then more heaters and heating milling machine retreat playback, is resumed operation, The defects of there are filling difficulty, interval time length, heat losses for this filling process greatly, regeneration flatness is bad.
