Abstract
The utility model relates to hot-mix plant recycling equipment for an asphalt mixture, which comprises a recycling material heating system, a recycling material storage bin arranged at the back of the recycling material heating system, a recycling material metering hopper arranged below the recycling material storage bin, a main mixing cylinder and a hot recycling material conveying device for conveying a recycling material to the main mixing cylinder, wherein a recycling material mixing cylinder is also arranged below the recycling material metering hopper, and a recycling agent metering hopper is also arranged above the recycling material mixing cylinder. Compared with the prior art, waste asphalt is uniformly mixed with a recycling agent in a secondary mixing cylinder before being put in the main mixing cylinder, thereby the recycling agent is uniformly pre-mixed with the waste asphalt, simultaneously the mixing time of the main mixing cylinder is shortened, and the production capacity of the whole equipment is improved.
Description
Technical field
The utility model relates to the hot in-plant reclaimed equipment of a kind of bituminous mixture.
Background technology
In recent years in order to respond country about requirements such as " building a conservation-minded society ", " developing a circular economy ", add the rise of the resource price of oil, building stones, what the various places highway division was all positive takes action, with " sustainable development " is aim, with development " green traffic " is target, and the recycling of old road asphalt material obtains paying attention to and paying close attention to again.A lot of research institutions and research institution begin one's study and promote the recycling technology of old road asphalt material.Wherein plant-mix heat recycle technology is exactly to use the most general a kind of regeneration in this class technology.The hot in-plant reclaimed equipment of common bituminous mixture does not have independent a mixing bowl to stir reworked material and regenerative agent specially, its common main technique flow process is: the hot reworked material that will heat is through directly sending into a mixing bowl of former life after measuring, spraying into a certain amount of regenerative agent then stirs in former life a mixing bowl earlier by reworked material and regenerative agent, and then drop into new aggregate and stir in same a mixing bowl with materials such as new pitch, stone flours, then these mixtures of material are transported to pavement construction as new material.New aggregate must be waited until after reworked material and regenerative agent stir and just can render in a mixing bowl with new pitch, stone flour in this process, has prolonged all material like this in the time of stirring link, has reduced the production efficiency of equipment integral body.Simultaneously this flow process also has the another one drawback: after new pitch and stone flour were rendered in a mixing bowl, new pitch was not only wrapped up in and has been attached to new aggregate surface, also wraps up in above the surface that has been attached to the reworked material aggregate.So not only waste new pitch and made the partial regeneration agent also wrap up in again simultaneously to be attached to new aggregate surface, made the attached property variation of wrapping up in of new aggregate and new pitch, thereby influenced the pavement performance of final compound.
The utility model content
Main purpose of the present utility model is to overcome the shortcoming of prior art, provides a kind of bituminous mixture hot in-plant reclaimed equipment.
The utility model adopts following technical scheme:
The hot in-plant reclaimed equipment of a kind of bituminous mixture, include the reworked material heating system, be located at this reworked material heating system rear the reworked material storage bin, be located at reworked material weighing hopper, the main a mixing bowl of this reworked material storage bin below and be used for hot reworked material is sent into the hot reworked material conveying device of main a mixing bowl, also be provided with the reworked material a mixing bowl below described reworked material weighing hopper, this reworked material a mixing bowl top also is provided with the regenerative agent weighing hopper.
Described hot reworked material conveying device is a belt conveyor.
By above-mentioned to description of the present utility model as can be known, compared with prior art, the utility model is owing to be provided with the reworked material a mixing bowl below the reworked material weighing hopper, before waste asphalt is put into main a mixing bowl earlier with its in inferior a mixing bowl with the regenerative agent stirring and evenly mixing, thereby realize that regenerative agent evenly mixes the mixing time that has shortened main a mixing bowl simultaneously in advance with waste asphalt, improved the production capacity of integral device, guarantee the attached property of wrapping up in of new aggregate and new pitch simultaneously, guaranteed the pavement performance of final compound.
Description of drawings
Fig. 1 is the part-structure schematic diagram of the utility model equipment.
The specific embodiment
Below the utility model will be further described by the specific embodiment.
With reference to Fig. 1, the hot in-plant reclaimed equipment of a kind of bituminous mixture of the present utility model, include reworked material heating system 10, be located at the reworked material storage bin 20 at reworked material heating system 10 rears, the reworked material weighing hopper 30 of being located at reworked material storage bin 20 belows, main a mixing bowl 40 and be used for hot reworked material is sent into the hot reworked material belt conveyor 50 of main a mixing bowl 40, also be provided with reworked material a mixing bowl 60 below reworked material weighing hopper 30, reworked material a mixing bowl 60 tops also are provided with regenerative agent weighing hopper 70.
Adopt the hot in-plant reclaimed technology of bituminous mixture of the said equipment, comprise the steps:
The pre-treatment and the metrology steps of new stone flour, its pre-treatment are meant storage and conveying etc.;
The pre-treatment and the metrology steps of new pitch, its pre-treatment is meant thawing, dehydration, heating, insulation etc.;
The pre-treatment and the metrology steps of new aggregate, its pre-treatment are meant that batching, cold burden are carried, oven dry heating, heat material promote, screening storage etc.;
The pre-treatment of waste asphalt and metrology steps, its pre-treatment are meant broken batching, cold burden lifting, heat tracing, storage etc.;
The step that the waste asphalt that metering is finished puts into time a mixing bowl 60, drop into regenerative agent and waste asphalt and regenerative agent are stirred in inferior a mixing bowl 60;
To put in the main a mixing bowl 40 and the step that stirs with waste asphalt, the new stone flour that metering is finished, new pitch and new aggregate that regenerative agent mixes.
Above-mentioned only is a specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
