Abstract
The utility model discloses a novel asphalt concrete heat regenerating device, which comprises an old asphalt concrete heat regenerating, processing and transmission device, a new aggregate processing and transmission device and a mixing tank. The mixing tank is arranged just below the downstream of the old asphalt concrete heat regenerating, processing and transmission device, and the downstream of the new aggregate processing and transmission device delivers new aggregates to the mixing tank from the side edge through a delivery device. The existing ordinary asphalt concrete plant adopts the original asphalt mixing station as the main body of the whole equipment and the old asphalt concrete heat regenerating equipment as the auxiliary device for heat regeneration, and the reclaimed materials after heating are delivered to the mixing tank of the original mixing station through the chute belt or other devices. The utility model solves the problem of the heat mixing and regenerating equipment of the existing plant that the reclaimed materials after heating are adhesive and can not be easily delivered during the delivery to the mixing tank from the side edge.
Description
Technical field
The utility model relates to a kind of asphalt-regenerating equipment, refers to the hot regenerating unit of a kind of novel asphalt concrete especially.
Background technology
Asphalt concrete pavement in use for some time can aged deterioration, need overhaul again.In revision, can produce a large amount of waste material---old asphalt concretes.Consider from environmental protection and recycling economy aspect, need carry out regeneration these old asphalt concretes.Hot in-plant reclaimed method is transported the batching plant back after the old asphalt pavement process being turned over dig exactly, concentrate broken again, quality requirement according to the road surface different levels, carry out proportion design, determine the adding proportion of old asphalt mixture, regenerative agent, new bituminous material, newly gather materials etc. and in lorry mounted mixer, to mix and stir into new compound by a certain percentage again, thereby obtain good Recycled Asphalt Pavement.Its groundwork flow process as shown in Figure 1.
Yet existing asphalt concrete regenerating equipment generally all is with primary agitator---new asphalt concrete mixer (hereinafter to be referred as primary agitator) is as equipment body, and old asphalt concrete is regenerated heating part as ancillary service.A mixing bowl wherein is the core component of primary agitator.Old asphalt mixture after the heating is sent a mixing bowl to by chute or belt conveyor or conveying worm or dolly.Because old asphalt mixture contains the composition of big viscosity such as antistripping agent, SMA, rubber asphalt, these pay-offs so the old asphalt mixture after the subject matter of this structure just is to heat bonds easily, make its steady operation for a long time, and in case the putty that bonds is cleared up very trouble.
The utility model content
Technical problem to be solved in the utility model is to overcome the deficiencies in the prior art, provide a kind of novel asphalt concrete hot regenerating unit, it can utilize the novel old asphalt mixture and the conveying hybrid mode of common new bituminous mixture, to reduce the problem of the old asphalt mixture bonding conveying equipment after heating as far as possible.
For solving the problems of the technologies described above, technical solution of the present utility model is:
The hot regenerating unit of a kind of novel asphalt concrete, comprise old asphalt concrete heat regeneration processing and conveyer, newly gather materials processing and conveyer and a mixing bowl, this a mixing bowl be positioned at that old asphalt concrete heat regeneration is handled and the downstream of conveyer under, newly gather materials and handle and the downstream of conveyer then will newly gather materials by the conveying device of newly gathering materials and send into a mixing bowl from side.
The regeneration of described old asphalt concrete heat is handled and conveyer comprises that the old asphalt concrete after the old asphalt concrete batching conveying device that is provided with in regular turn, old asphalt concrete drying and heating device, the heating stores metering device, and described a mixing bowl be positioned at old asphalt concrete store metering device under; The top of a mixing bowl also is provided with the storage metering flusher of the additive that is used for old pitch reducing/regenerating.
Described newly gathering materials handles and conveyer comprises the cold batching conveying device of newly gathering materials that is provided with in regular turn, the drying and heating device that newly gathers materials, the storage device that newly gathers materials, the scale hooper that newly gathers materials; Described a mixing bowl top also is provided with the storage metering device of material such as stone flour pitch.
Also be provided with the screening plant that newly gathers materials between described drying and heating device that newly gathers materials and the storage device that newly gathers materials.
This device also comprises the exhaust gas processing device that old asphalt concrete drying and heating device and the tail gas that drying and heating device ejected that newly gathers materials are handled.
Described conveying device of newly gathering materials is chute or belt conveyor or conveying worm or dolly.
After adopting such scheme, because the utility model is placed on old asphalt concrete heat regeneration storage bin below with a mixing bowl, add a mixing bowl and will newly gather materials from the side as admixture, this novel hot in-plant reclaimed equipment is that old asphalt concrete is added the main body of thermal agitation main building as complete equipment, as its ancillary service, a mixing bowl wherein is the core component of reclaim equiment part with primary asphalt concrete mixer.Old asphalt mixture after the heating is directly rendered in a mixing bowl of its below through weighing hopper, sends a mixing bowl by chute or belt conveyor or conveying worm or dolly from side and newly gather materials.Owing to newly gather materials and do not possess caking property, so the main feature of this structure just is to have avoided to carry the sizing problem that old asphalt mixture brought after the heating, has reduced breakdown rate.
Description of drawings
Fig. 1 is the process chart of hot in-plant reclaimed mixing plant;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
What the utility model disclosed is the hot regenerating unit of a kind of novel asphalt concrete, as shown in Figure 2, is preferred embodiment of the present utility model.This device comprises old asphalt concrete batching conveying device 1, old asphalt concrete drying and heating device 2, old asphalt concrete after the heating stores metering device 3, the storage metering flusher 4 that is used for the additive of old pitch reducing/regenerating, the cold batching conveying device 5 of newly gathering materials, the drying and heating device 6 that newly gathers materials, the screening plant 7 that newly gathers materials, the storage device 8 that newly gathers materials, the scale hooper 9 that newly gathers materials, the conveying device 10 of sending newly gathering materials into a mixing bowl, the storage metering device 11 of materials such as stone flour pitch, to old asphalt concrete drying and heating device 2 (also claiming hot regeneration and drying tube) and exhaust gas processing device 12 that the tail gas that the drying and heating device 6 that newly gathers materials is ejected is handled, and a mixing bowl 13 that all material is mixed together.Key of the present utility model is: described a mixing bowl 13 be positioned at old asphalt concrete store metering device 3 under, the conveying device 10 of newly gathering materials then is positioned at the side of a mixing bowl 13.The described conveying device of newly gathering materials 10 can be chute or belt conveyor or conveying worm or dolly.
