Description

A kind of electric heating asphalt tank container
Technical field
The utility model relates to a kind of electric heating asphalt tank containers.
Background technique
Currently, the main such as under type of the bulk bin of conveying asphalt heats: fire tube heating, heat-conducting oil heating and electric heating. For fire tube heating, fire tube, which wriggles, is distributed in tank interior, is fired fossil fuel by manual operation portable burner It burns and generates high-temperature flue gas, high-temperature flue gas is transmitted to inside fire tube, thus heated asphalt.Since manual operation cannot accurate control temperature Degree and fire tube internal temperature unevenness, cause the part asphalt temperature around fire tube too high and coking occur and goes bad;It is flowed in fire tube Flue gas take away amount of heat and lead to heat loss;Fire tube diameter is big, need to occupy larger space, and the amount of storage of pitch is caused to become smaller. For heat-conducting oil heating, heat-conducting oil pipes bending is distributed in tank interior, and heavy oil, light oil etc. are heated filling heat-conductive oil pipe In, it is exchanged by heat and realizes heating to pitch.This solve to a certain extent pitch by temperature it is excessively high caused by go bad Problem, but since the oil guide pipe of tank interior is by being welded, weld cracking will lead to conduction oil and be mixed into pitch.For For electric heating, temperature control heating component is built in tank interior, thermal energy is converted to electric energy and heats pitch, by adjusting automatically Whole temperature switch, can be excessively high to avoid fire tube heating temperature and keep pitch rotten, and pollution ring will not be generated during heating The exhaust gas in border.But electric heating assembly is directly inserted into asphalt tank, with Asphalt Contactor, leads to the pitch attachment that part is rotten On electric heating assembly surface, to influence heating effect.In addition, if electric heating tube breaks down, since bitumen solidification is easy Electric heating tube is caused to be difficult to take out.
CN108190275A discloses a kind of asphalt container heating device, including tank body, Drawing-Core electrical heating elements, set Cylinder temperature sensor, Drawing-Core electrical heating elements include sleeve, electrical heating core, connecting flange and electrical heating core connecting flange.Even One end of sleeve is arranged in acting flange, and when the sleeve is plugged in the tank interior, connecting flange is arranged in tank wall On, electrical heating core is fixedly arranged on electrical heating core connecting flange, when electrical heating core is plugged in sleeve inner, connecting flange and electric heating Core connecting flange is adapted;Sleeve outer wall is provided with jacket temperature sensor, for measuring the temperature of pitch.The patent document will Temperature sensor is set to sleeve outer wall, Accurate Determining can not be carried out to the temperature near electrical heating core, to will lead to reality Border heating temperature is excessively high and causes pitch rotten and the problem of electrical heating elements are burnt.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of electric heating asphalt tank container, it can be with Accurate Determining Temperature near electric heating tube to avoid causing pitch to go bad because heating temperature is excessively high, while can reduce electric heating member Part damage.The utility model it is a further objective that provide a kind of electric heating asphalt tank container, can be to avoid electric heating Element is damaged because of shaking.Specifically, the utility model includes the following contents.
