Description
Technical field
The present invention relates to technical field of engineering machinery, reclaim asphalt heater in particular to one.
Background technology
When the asphalt of bituminous paving is recycled, need asphalt is heated.At present,
Reclaim asphalt heater and all contain the critical piece such as heater and heating cylinder.In existing product, heating
Device is typically mounted on the feed end of heating cylinder, when asphalt rotates and along cylinder in heating cylinder
Inwall move to discharge end after, often result in inwall and the lifting of cylinder discharge end owing to internal temperature reduces
Producing the situation of sizing on device, this not only have impact on the formation quality of material curtain, and reduce cylinder adds thermal effect
Rate, and need workman periodically sizing to be cleared up, have impact on production continuously, thus add user
Use cost, be unfavorable for its marketing.
It is therefore proposed that one adds thermally relieved, and the recovery asphalt heater of sizing situation will not be occurred just to show
Obtain particularly significant.
Summary of the invention
In order to solve at least one above-mentioned technical problem, it is an object of the present invention to provide a kind of heating can
Lean on, and will not the recovery asphalt heater of sizing.
For achieving the above object, the embodiment of first aspect present invention provides a kind of Colophonium that reclaims and adds hot charging
Put, including: cylinder, described cylinder has feed end and discharge end；Heater, described heater is with described
Feed end connects, for injecting high-temperature gas in described cylinder；With wind-guiding reflux, described wind-guiding returns
Stream device is arranged on the described discharge end of described cylinder, for being guided extremely by described discharge end effluent air
The outer wall of described discharge end.
The recovery asphalt heater that the embodiment of first aspect present invention provides, can be by the discharging at cylinder
Wind-guiding reflux is set on end, thus discharge end expellant gas is guided by this wind-guiding reflux available
On the lateral wall of the discharge end of cylinder, so as to utilize discharge end expellant gas again to heat in cylinder
Material, thus just can slow down the cooling rate of the discharge end of cylinder, it is to avoid the discharge end of cylinder interior
Wall and raising material unit be sizing owing to temperature is too low, is effectively improved the formation quality of material curtain, improves product
The efficiency of heating surface, and extend the cleaning cycle of cylinder accordingly, it is ensured that the continuous prodution of product.
It addition, the recovery asphalt heater in above-described embodiment of present invention offer can also have the most attached
Add technical characteristic:
In technique scheme, described wind-guiding reflux includes: plenum chamber, has in described plenum chamber
Cushion chamber, the sidewall of described plenum chamber is provided with opening, and described discharge end passes on the sidewall of described plenum chamber
