Abstract

The utility model relates to a hot blast circulating heating device which is mainly used for heating asphalt mixing materials in reuse of materials of asphalt pavements. The device comprises a combustion device and a heating roller, wherein the combustion device is formed by a combustion chamber and a burner. The device is characterized in that the combustion chamber is connected with a blower; and an exhaust fan is mounted on the roller, and is connected with the combustion chamber through a pipeline. The device can deliver the remaining heat at the tail end of the heating roller into the combustion chamber for reuse through the exhaust fan and the pipeline, thereby effectively improving heat efficiency. Meanwhile, the device can effectively control the temperature of the material heated, and avoids the phenomenon that asphalt ages due to over-high heating temperature.

Description

A kind of heat wind circulation heating equipment
Technical field:
The utility model is mainly used in the asphalt highway material regeneration when utilizing, and bituminous mixture is heated, and is specifically related to a kind of heat wind circulation heating equipment.
Background technology:
During the bituminous mixture regeneration of asphalt highway, need heat it.Present heater is made up of burner and heated roller.The flame of burner directly heats the compound heated roller in the cylinder, and operation easier is bigger, and very easily pitch is caused aging.In addition, after heat and heated material carried out interchange of heat, some remaining heat all was discharged in the atmosphere, not only wasted energy, but also caused environment pollution.
Summary of the invention:
The utility model provides a kind of heat wind circulation heating equipment, is that it carries out indirect heating with hot blast to heated material, but not currently used flame directly heats, so can effectively avoid the further aging of heated material.Simultaneously, can be with the waste heat Recycling, thus improve the efficiency of heating surface effectively.
The realization the technical solution of the utility model is: comprise burner, cylinder, burner connects cylinder, and burner is made up of combustion chamber and burner, and charging aperture and discharging opening are set on the cylinder.It is characterized in that the combustion chamber connects blast fan, an end of cylinder is equipped with induced draft fan, and induced draft fan connects the combustion chamber by pipeline.
Between described cylinder and the burner temperature pick up is installed, on the discharging opening of cylinder temperature pick up is set, between cylinder and the induced draft fan temperature pick up is set.
The ground of cylinder and level is the inclination angle of 0~4 degree, and promptly the feed end of cylinder is higher than the discharge end of cylinder.
The utility model is delivered to the combustion chamber with the after-heat of heated roller terminal by induced draft fan and pipeline and is utilized, can improve the efficiency of heating surface effectively, also can be by opening or close the heat release cylinder and control the temperature that is heated material effectively, thus it is too high and cause the generation of the phenomenon of ageing of asphalt to avoid taking place heating-up temperature.

Temperature pick up 9 is set between the cylinder 4, and the discharging opening 7 of cylinder 4 is provided with temperature pick up 8, and induced draft fan 6 connects combustion chamber 2 by pipeline, and pipeline connects heat release pipeline 14 by threeway 5, and heat release pipeline 14 is realized closing of heat release pipeline or open by cylinder 15.
With above-mentioned facility matching used PLC and program software thereof in addition, by the signal of temperature pick up transmission, PLC and program software thereof are realized control automatically.
Illustrate:
1, by the survey data of temperature pick up to air intake, air outlet and discharging opening temperature, be transferred to the action of PLC and program software control cylinder thereof, realize the closure or openness of threeway, reach the control of compound heating-up temperature.
2, after compound heating is finished, open air draft, to the combustion chamber processing of lowering the temperature.
3, the support facility of burner and cylinder and cylinder is prior art in the utility model, and their structure of Therefore, omited is described.
