The technical solution adopted in the utility model is for this reason: comprise the support of cylinder body and support cylinder body, cylinder base is provided with electric heater unit, and cylinder body top is provided with infrared heating device; Described inferior part of the cylinder block can oscilaltion.
Described electric heater unit is flat electrothermal tube, and cylinder base is provided with the mounting groove that flat electrothermal tube is installed.
Described infrared heating device is multilayer Ti-Ni alloy web, high efficiency infrared heater, is arranged at the top side of mixing plant.
Described inferior part of the cylinder block moves up and down by hydraulic-driven.
Also comprise stirring motor and be arranged on the agitator that cylinder body both sides are driven by stirring motor.
A course of work for combustion gas and electric Hybrid Heating bituminous mixture down-sliding type mixing plant, carry out according to following steps:
Step 1: first ato unit preheating, open generator, then open electric heater unit and carry out preheating;
Step 2: open gasholder liquid phase valve, guarantee liquid phase pressure; Then open gasification furnace, then open top infrared heating device work;
Step 3: after heating, open agitator pitch is stirred;
Step 4: after finishing, close bottom electrical heating and top infrared element, mix stoneware and still work;
Step 5: close agitator;
Step 6: reduce a mixing bowl cylinder bottom, cleaning clout.
The utility model has the advantages that: 1) the utility model adopts electrical heating in cylinder base, cylinder base is conducted to preheating, thereby played cylinder base pitch and can not stick to the effect of cylinder body; Cylinder body top adopts infrared heating simultaneously, utilizes the permeability of infrared heating, has guaranteed the heating effect of pitch;
2) electrical heating of the utility model setting is pancake electrical heating, and its volume is little, is applicable to being arranged on cylinder base, and the utility model adopts nested mounting means, makes total more compact, can not affect the integral installation of mixing plant;
3) the utility model inferior part of the cylinder block can oscilaltion, the conveniently cleaning to pitch clout like this, and the cylinder base that only need decline when cleaning can realize.
