Description
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.
