Description
Technical field
The utility model relates to a kind of pitch remixing locomotive, specifically is used for the mix and blend of new and old asphalt material.
Background technology
Flexible pavement inevitably can produce the defectives such as rut, depression after long-term the use, these defectives will further be accelerated pavement damage, affect traffic safety.The in-situ heat regeneration method is a kind of flexible pavement restorative procedure of latest development, and its specific embodiment is as follows: at first preheat depositing defective flexible pavement.Because pitch thawings of being heated, itself and the adhesion decline of aggregate are when this road surface is heated to uniform temperature, after namely reaching the road surface and softening, again by in addition milling of milling equipment.Can under less milling active force make flexible pavement by original shakeout compaction state be transformed into loose stacking states, and can not destroy wherein aggregate because softening road surface can not produce excessive resistance to milling and plane operation this moment.Thereby the old asphalt mixture that milling goes out do not change its grating, still can reuse.But old asphalt mixture still needs it is added new pitch because having the material loss in inevitable ageing of asphalt, the mechanism process and improving the factor such as former road surface grating, regenerative agent, the materials such as new bituminous mixture.When adding new material, still need old asphalt mixture through again heating of row, after further stirring at a certain temperature, by the pressing that paves of the equipment such as paver, form qualified new road surface again.
In actual use, the new pavement quality that adopts the method to repair is stable not, sometimes even do not reach acceptance requirement.Its reason is: existing technique be use some preheating locomotives with road-surface heating to uniform temperature, dig the road surface by the milling machine turnning and milling of closelying follow, milling forms the old asphalt mixture of loose depos-its.After this, because the remixing stage need to add new bituminous mixture, new bituminous mixture needs to deliver and unload to the hopper of remixing Che Yiduan by being in the middle tipping truck of milling locomotive and remixing locomotive, and is delivered on the old asphalt mixture according to quantity by the conveyer in the hopper.This just makes the milling machine vehicle tail end separate suitable length one segment distance before the remixing locomotive promotes stirring, and in this segment distance, old asphalt mixture is exposed in the cold air, and can not get heating.So in old process program, before remixer promotes stirring, set up a heater with heat compensation loss and further heating old asphalt mixture, and for improving the efficiency of heating surface, spiral was set before heater divides device and divide old asphalt mixture to increase heating surface (area) (HS.Though such scheme can make the temperature of old asphalt mixture obtain certain raising, but because milling machine vehicle tail end to remixing locomotive heater front end still has one section very long distance, and locomotive driving speed needs very slow during because of operation, this just makes this section old asphalt mixture be exposed to for a long time and lets alone heat radiation in the cold air, can not get heating.If at windy area, meet the construction of strong wind weather or autumn and winter season, because the expansion of the temperature difference and the reinforcement of convection action, material a large amount of heat that scatters and disappears will be made.This just makes the heater of back that very large heating power need to be provided, and one expends a large amount of fuel, and is economical not; Two also make heater excessive long, make mobility, the trafficability characteristic variation of car load.Old asphalt mixture is divided into certain thickness usually, heater is to its limited time that heats again, and old asphalt mixture exists heat conduction bad, the unfavorable factors such as rapid heat dissipation, thereby the heat that heater is produced is limited to the mixed material heating effect, the material on top layer is fully heated, and the temperature gradient of through-thickness is larger, cause different-thickness place material to be in different character and state, be unfavorable for the follow-up operation that mixes, and and then affect the final mass of green road surface.And during the remixing stepwise heating, old asphalt mixture is still and is in the semi-open environment, needs further to improve heating power.And simple dependence increases the method that heat is supplied with, and not only will increase greatly cost, and tend to make the top layer material to burn, and the uneven phenomenon of being heated still exists.Long bringing-up section, making the remixing locomotive is to satisfy certain mobility and trafficability characteristic to have to shorten the length that stirs section, it is even not that this just makes compound stir, and affects the green road surface quality.Therefore, the old asphalt mixture after the milling machine turnning and milling is dug is heated fully and is stirred when the remixing stage is being added necessary new material, and making certain quality requirement that reaches that green road surface can be stable is a major issue.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provide a kind of pitch remixing locomotive, can make the heating of new and old asphaltene and stir more abundant and even, thereby form the new compound mix with temperature stabilization, guaranteed the quality requirement that reaches that the road surface of new formation can be stable.
The technical scheme that provides according to the utility model, a kind of pitch remixing locomotive comprises old material elevating conveyor, virgin material mixing bunker, virgin material hopper conveyer, solid material feed bin, liquid material feed bin, buffering hopper, mixer, heated air circulation device, rear portion conveyer and car body, it is characterized in that: the car body rear end is rotationally connected old material elevating conveyor, old material elevating conveyor both sides connect the hydraulic pressure strut, and hydraulic pressure strut upper end is fixed on the car body.Described old material elevating conveyor rear end connects the buffering hopper, and the buffering hopper is fixed on the mixer.The virgin material mixing bunker is fixed on the car body, other solid material feed bin and the liquid material feed bin of connecting of virgin material mixing bunker.Described virgin material mixing bunker bottom is provided with virgin material hopper conveyer.Mixer is fixed on lower end, car body middle part, and the mixer top is heated air circulation device fixedly.Described mixer rear end connects the rear portion conveyer.
Described old material elevating conveyor, virgin material mixing bunker, virgin material hopper conveyer, buffering hopper, mixer, heated air circulation device, rear portion conveyor surface all cover one deck alumina silicate heat-preservation cotton.
Described virgin material mixing bunker rear end is provided with the virgin material bin stopper.
