Description
Technical field
The utility model relates to a kind of pair of bituminous mixture lifting machine pumped (conveying) mediums to heat combustion gas booster-type heating device, answer
For double-layer local hot in-place recycling field.
Background technique
, double-layer local hot recycling project be related to asphalt transhipment, process is related to promoting conveying, mixed to pitch in the process
It closes and expects that the heating of locating narrow space mixture mends temperature, heat preservation concerning Project Success.
2, transmission process asphalt mixture heating needs power big, and computer heating control is accurate, and heating process can not be by environment
Condition influences.
3, currently used for the mode of asphalt mixture heating there are commonly electric heating and Gas Infrared heating (injection type+in
Press premixed combustion).Electric heater unit needs to configure huge generating set, current outdoor study hot recycling unit by expense and
Device space limitation can only install small power generator group, and heating power is low, and heating time is long, is not able to satisfy job requirements.Often
By burning oxygen supply, pressure is low is limited for Gas Infrared heating, easily occurs being tempered under the influence of wind-force factor outdoors dangerous
Combustion position.Traditional heating device directly directly heats asphalt, if control failure, will appear showing of burning once in a while
As.
4, a kind of elevator combustion gas booster-type heating device in view of the foregoing drawbacks, is proposed.The device characteristic: 1, burning oxygen supply
Pressure is big (>=800KPa), completely not by outdoor windage.2, the device passes through heating plate radiant heating asphalt, Du
The phenomenon that asphalt is burnt in heating absolutely, and pass through the automatic control of the temperature sensor realization combustion conditions on heating bottom plate
System.3, device oxygen supply air supply duct caliber is small, is convenient for engineering truck site layout project, beautiful.
Utility model content
The utility model can mix mixture progress in view of the foregoing drawbacks, and it is an object of the present invention to provide a kind of structurally reasonable to pitch
Uniformly heated combustion gas booster-type heating device.
The technical solution adopted in the utility model is thus: bituminous mixture lifting machine feeding device include conveying scraper plate and
Upper and lower bottom plate, mixture are constantly sent to eminence from lower by upper plate under traction scraper plate effect, and lower plate bearing is scraped
Plate.As heating space, linear heater is placed in the space two sides in space between upper and lower bottom plate, directly heats to upper plate, leads to
Overshoot heated asphalt mixture.Lower plate is insulation board.The mounting temperature sensor on upper plate is realized to the accurate of heating
Control.
Mixed material heating device includes that 10 groups of linear heaters and gaseous mixture supply control system.Gaseous mixture supply control system
System includes combustion unit and air element, and the uniform blending transportation of air and combustion gas by pressurization is lighted and added to linear heater
Hot bottom plate is realized by the heat radiation of bottom plate to asphalt mixture heating.
Air distributor is provided in air delivery to the path of heater in the air element.
The utility model has the advantages that:
1, the utility model uses pressurized combustion, and oxygen supply pressure is big (>=800KPa), combustion conditions not by outdoor wind-force because
The influence of element, it is safe and reliable.
2, the utility model elevator heating interval is located in the narrow space of elevator upper and lower bottom plate, and power is big, heating
It automatically controls, meets mixture in transmission process and mend temperature, constant temperature thermal requirements.
3, the requires of the utility model oxygen supply air supply duct caliber is small, is also applied for the utility model for other existing works
The transformation of journey vehicle burner.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
1 it is combustion unit in figure, 2 be air element, 3 be linear heater, 4 be upper plate, 5 be air distributor, 6 is
Scraper plate, 7 be chain, 8 be igniter, 9 be lower plate, 10 be temperature sensor.
Specific embodiment
The utility model includes gaseous mixture supply control system, which includes combustion unit and air element, will be passed through
Increased air and fuel gas transmission to heater light heating, are realized by the heat radiation of bottom plate to asphalt mixture heating.
Air distributor is provided in air delivery to the path of heater in the air element.
When the utility model is used: pressure control is provided on the combustion unit and air element, according to reality
After situation adjusts gaseous-pressure and air pressure, it is passed through to distributor and is delivered in heater, the utility model uses
Heater be linear heat device, then lighted a fire by igniter；The heat that burning generates in heater acts on bottom
Plate acts on asphalt by way of upper plate heat radiation.
The utility model is realized by the way of heat radiation to asphalt mixture heating, therefore the upper plate of the utility model
It should be made of tool high emissivity, oxidation-resistant material.
