2. the present invention is essentially identical using the calorific value of electric heating device per unit area in the longitudinal direction, homogeneous heating,
Avoiding heating uneven causes local pitch to lead to the problem of coking and aging due to temperature is excessively high.
3. the present invention has the temperature control device for detecting oil temperature and heating member respectively, pitch overheat carbonization, present invention set are prevented
Temperature sensor detection jacket temperature on cylinder, works after a period of time, the temperature of sleeve reaches set temperature, and sleeve temperature control is opened
Automatic disconnection is closed, after the temperature of sleeve is absorbed, sleeve temperature detect switch (TDS) is closed, and electrical heating core continues to heat, when heating one section
Between after, pitch mobility improves in tank, and the temperature of sleeve is always held under set temperature, and electrical heating core is continued for work
Make, asphalt temperature gradually rises.The temperature sensor detection asphalt temperature being fixed in tank, sets when the temperature of pitch in tank reaches
During definite value, oil temperature temperature detect switch (TDS) disconnects, and heating stops.
4. the present invention is less using preparation before connection joint makes heating is connect soon, simple to operate.
Using six groups of parallel connection electrical heating cores, 5. every group works independently the present invention, when one group of damage open circuit, does not influence other
Group work is not in because can not heated asphalt situation about cannot unload.
6. the present invention using can core pulling electric heating device, when heating core damages, can direct demounting bolt, by electrical heating
Core is replaced.
7. the present invention heats the pitch of asphalt container using electrically heated method, avoid and fired when being heated using flue
The pollution that burner spray burning generates, energy conservation and environmental protection.
