Description
Technical field
The utility model belongs to the melting unit technical field of pitch.
Background technology
Pitch is the organic binder in bituminous concrete, by hydrocarbon and nonmetallic（Oxygen, sulphur, nitrogen etc.）Derivative
Composition, can generally be dissolved in the organic solvent such as trichloro ethylene, stupid, at normal temperatures in gelling state, only be heated to more than softening point
Temperature（130℃~165℃）So that it becomes just can be used for construction or indoor index Test after flow regime.
Therefore, before many pitch index Tests start, the tank bucket for filling gelling state pitch can be placed in electricity by experimenter
Pour out and use again after heating and melting on stove.The method limitation that liquid bitumen is taken in this heating is larger, is mainly reflected in following
Aspect：1st, pitch is mainly by the macromolecular components such as saturation point, fragrance point, colloid, asphalitine, polymer, ideally, pitch
Each constituent should be in uniform distribution, can ensure that pitch possesses preferable warming during in uniform state
The material properties such as property, adhesiveness.However, pitch is when forming gel state, due to each component molecular weight inside pitch and relatively close
The differences such as degree, the composition for tending to cause molten asphalt middle-molecular-weihydroxyethyl heavier such as colloid sinking, lighter fragrance grades floating,
So that pitch internal composition is isolated, the asphalt performance of different layers position is different in same sample（For example：Layer more than saturation point content
Position, bitumen consistency is relatively low, and needle penetration becomes big；The more layer position of gum level, viscosity becomes big etc.）, it is impossible to ensure that it embodies drip
Blue or green original material property.By the way of traditional kind local heating, heat it is uneven, different layers position melt after pitch into
Divide inconsistent, the problem of pitch is isolated is not solved still, it is larger to measure pitch scale error if for pitch index Test；
2nd, from outside to inside, outside heater or zone of heating has most heat to be dissipated in airport to this mode of heating, directly
The heat for acting on pitch is less（I.e. the efficiency of heating surface is low）, the thawing speed for ultimately resulting in pitch is more slow；3rd, ordinary circumstance
Under, asphalt temperature exceedes its softening point（Generally more than 65 DEG C）More than, the gelatinized of itself will be broken, and gradually become stream
Dynamic state.But most pitches（Especially modified pitch）Only heating-up temperature can just be embodied enough after reaching 130 ~ 165 DEG C
Strong viscosity, can carry out many performance tests of asphalt and aggregate（The premise of such as a whole set of index Test of Marshall is
Before product asphalt temperature reach 130 DEG C and more than）；Heating can not be accurately controlled using traditional mode of heating, in heating process
Temperature, even if by asphalt melting but still not reaching test temperature, then needs progress reheating could be up to standard, and reheating one
Aspect delays experiment progress, and two be to be easily caused ageing of asphalt, influence analysis of experiments result；4th, drip is melted in existing export
Blue or green mode is to set discharging opening in tank bottom of the barrel or directly topple over, and in practical operation, reaches the thawing drip of test temperature
Green grass or young crops flow to tank body discharging opening or when run up to it is a certain amount of can topple over when, temperature is generally reduced under test temperature,
I.e. this method can not rapidly export the thawing pitch for reaching test temperature（Pitch up to standard）.
Utility model content
The utility model, which is intended to provide, a kind of prevents that pitch isolation, the efficiency of heating surface are high and can quickly export the room of pitch up to standard
The interior experiment quick heating extraction equipment of pitch.
Technical scheme：A kind of quick heating extraction equipment of pitch for laboratory experiment, including for placing pitch storage
The base of bucket, be provided with the base can oscilaltion cantilever, the cantilever one end is provided with rotatable and pluggable pitch storage

Storehouse, the extraction conduit is communicated with hollow shaft and is connected by rotating seal, and the pitch efferent duct connects with pitch bin
Connect；Some stirring vanes are provided with the hollow shaft, blade interior is provided with the hollow shaft perisporium between heater, blade
On be provided with some pitches and draw holes.
Beneficial effect：The utility model is provided with stirring vane, stirring vane in hollow shaft and carries heater so that
Stirring vane is preheated to after certain temperature, and hollow shaft is also heated, and control cantilever declines until the pitch of hollow shaft and gelatinized
Contact makes it gradually melt, and hollow shaft continues decline and breaks fix-bitumen, starts stirring after molten asphalt reaches certain limit
Blade so that each constituents of pitch are well mixed, and are heated while stirring；Start draw-off pump, reach the thawing drip of test temperature
It is blue or green to be entered in time by pitch absorption hole inside hollow shaft, then pitch bin is entered by pitch efferent duct, then by pitch
Efferent duct is exported, and is used to pitch up to standard test in time, it is ensured that the quick progress of experiment.Advantage of the present utility model exists
In：1. the mode of heating from the inside to the outside used, stirring vane is all acted in pitch completely into pitch inside, heat
Portion, scattering and disappearing, aerial heat is less, and the efficiency of heating surface of pitch is higher；2. heat and stir the mode carried out simultaneously so that
The composition of this stratified sedimentation of fix-bitumen Central Plains（Oils, asphalitine etc.）Sufficiently mixed, prevent pitch from isolating, most
Keep asphalt component as former state to big degree；3. with thermal source（Stirring vane and hollow shaft）The thawing pitch directly contacted reaches at first
Test temperature, pitch draws hole（On agitating shaft between stirring vane）The pitch of absorption is exactly to reach melting for test temperature
Change pitch, pitch enters pitch bin by extracting conduit, mode exported compared to traditional pitch, one be can be in time
The fusion pitch for being up to test temperature is rapidly exported for testing；Two be to prevent pitch superheated up to standard, causes pitch
Mutation occurs for component；4. outside this heating extraction equipment is independently of pitch storage bucket, without doing any improvement to pitch storage bucket,
Suitable for the pitch storage bucket of different size size, have a wide range of application.
Further, the cantilever is connected by electrical-controlled lifting bearing with base, and electrical-controlled lifting bearing is provided with micro electric
Control platform；Contact type temperature sensor is provided with the hollow shaft free end, torque sensor is installed in hollow shaft, it is described
Heater is heating module；The contact type temperature sensor, torque sensor, draw-off pump, heating module are and micro electric
