Description
Technical field
The present invention relates to a kind of slender type twin shaft blunger, specifically a kind of slender type with heating and heat preserving function is double
Axle blunger, for mixing and stirring for sheet pavement in-situ heat regeneration construction Asphalt Mixture.Belong to asphalt pavement construction machinery to set
Standby technical field.
Background technology
Blunger is a kind of for being mixed a variety of different materials and forming the plant equipment of mixture, is widely used in
In each industrial production and engineering practice.As a key link of Heat reclaimation technology in site for asphalt surface, asphalt is mixed
The quality of pavement quality is directly influenced with the quality of quality.However, existing blunger mix and stir after asphalt,
Its material temperature often relatively low requirement that can not reach construction when being bonded with road surface, so as to reduce pavement quality.Secondly, it is existing to mix and stir
The abrasion-proof backing block of device is assembled by multiple small wearing plates, and one piece of block dismounting is generally needed when serious wear need to be changed, than
It is more numerous and diverse.Finally, compensation of the existing slender type twin shaft blunger to error is mostly error caused by the manufacture of product, but when thin
The length of elongated twin shaft blunger is longer, and agitating shaft is single overall major axis, when the occasion that local environment temperature change is larger
When, error does not often have remedial measure caused by difference variation.
The content of the invention
The present invention some problems existing for existing equipment, it is proposed that a kind of slender type with heating and heat preserving function is double
Axle blunger, it can be heated and be incubated to the new old asphalt mixture mixed and stirred, it is ensured that when its material temperature reaches construction
Required paving material, in order to realize the excellent bonds with road surface, ensure pavement quality.Secondly, this leptosomatic twin shaft
It blunger, can not only compensate because of error caused by the manufacturing, while can also make up due to the change of temperature and bring
Error, realize that double compensation is double and make up；Finally, the abrasion-proof backing block of the blunger is movable, can be when any need
To mount and dismount, more convenient and quicker.
In order to solve the above-mentioned technical problem, the present invention is adopted the following technical scheme that:
A kind of slender type twin shaft blunger with heating and heat preserving function, including mix cylinder and two agitating shafts.The cylinder of mixing is thin
Elongated, its section are in ω shapes, carry multigroup stirring block on two agitating shafts, and each stirring block on same root agitating shaft is along stirring
Axle helically arranges that the stirring block on two agitating shafts is in axial arranged crosswise.Two agitating shafts, which run through, mixes cylinder both ends.Its feature
It is：
The cylinder of mixing is made up of outer cylinder body and inner cylinder body, and insulation material is filled between outer cylinder body and inner cylinder body.The insulation material
Preferably ceramic fibrous material, can also select asbestos, but asbestos are harmful to not environmentally and to human body, prepare and use during note
Meaning protection.
Described to mix the abrasion-proof backing block that inner cylinder sleeve dress section is in ω shapes, abrasion-proof backing block is arranged on the inwall for mixing cylinder and is fixed on it
End face, to prevent mixing the frayed seriously influence use in the long-term whipping process of compound of the inner cylinder body of cylinder, at this moment it need to only tear open
Unload replacing down.
It is described to mix cylinder, its top covering heating plate.Heating plate（Also referred to as heating pad wall）It is by burning fuel then
The required heat of system simultaneously heats the compound mixed in cylinder by way of radiation, its temperature is increased to certain limit.
The heating plate, the heating plate heated using Gas Infrared, can also use Hot-blast Heating mode.
The agitating shaft is segmented, using connection short axle connection between each segmentation of agitating shaft.The cylinder of mixing is connecting
Short axle top position is provided with mounting bracket, mounting bracket hoisting axis bearing, and connection short axle is arranged in bearing block.Connect short axle and stirring
One of axle, which is segmented into, to be fixedly connected, and is connected with another segmentation of agitating shaft using spline.It is big in temperature to solve agitating shaft
Expanded with heat and contract with cold in changes in amplitude environment problem.
The stirring block, by stirring vane, mounting seat, mix arm and connecting plate forms, mounting seat is fixed on agitating shaft, is mixed
Arm is fixed in mounting seat and vertical with agitating shaft, and connecting plate, which is located at, mixes arm end, and stirring vane is arranged on connecting plate.
Compared with prior art, the invention has the advantages that：
The present invention is heated using heating plate to the compound mixed in cylinder, it is ensured that is paved to the asphalt temperature foot on road surface
It is enough, it is easier to hot adhesion to be produced with road bottom surface, so that the reliability of pavement quality is improved significantly.Torn open using drawing and pulling type
The abrasion-proof backing block unloaded, labor intensity when making that abrasion-proof backing block need to be changed because of serious wear substantially reduce, and save the time, improve
Operating efficiency.The invention belongs to a kind of leptosomatic twin shaft blunger, for needing transmission over long distances to mix and stir the field of compound
To close especially suitable, it can not only realize the floating of bearing, and the axle in structure is also at quick condition at work, so as to
The error brought of manufacture can both be made up by reaching, can be changed again with compensation temperature caused by error, realize double fault difference double compensation, make
The overall accuracy of structure is further improved.The present invention is applied to sheet pavement in-situ heat regeneration technical field of construction, institute
The structural repair of use is convenient, error is small, new old asphalt mixture is mixed and stirred in heating, make the bituminous paving quality after construction it is higher,
Effect is more preferable.
