Abstract
The utility model discloses a kind of conduction oil electrically heated rod, it is that a kind of employing is filled conduction oil in excellent shell, and heating element is earlier with heat-conducting oil heating, and conduction oil is with heat transferred heat bar shell and a kind of electric heater unit that required heat medium is heated.This heating rod can be used for the heating to former wet goods danger medium, relatively has advantages such as long service life is safe and reliable with existing heating rod.
Description
Affiliated technical field
The utility model relates to a kind of crude oil storage tank heating electrically heated rod, the particularly electrically heated rod that conducts heat with conduction oil.
Background technology
Existing crude oil storage tank heating electrically heated rod, it is common doing heater element with electric heating tube, electric heating tube is contained in the excellent shell, fill metal dust or cast aluminium between rod shell and heating element, the temperature control of heating rod is located at the surface of heating rod, this scheme exists the very big heating element of the temperature difference between heating element and excellent shell surface very short useful life, heat bar shell in a single day expose in air excellent shell surface temperature will be raised in very short time very high, the generation of fire hazardous, explosion accident thus.
Summary of the invention
The purpose of this utility model just provides a kind of electrically heated rod that can effectively solve above-mentioned shortcoming.
The technical scheme that its technical problem that solves the utility model adopts is that heater element is contained in the excellent shell, fills conduction oil in the excellent shell and the temperature of heat conduction is controlled.
The beneficial effects of the utility model are:
1, heater element directly contacts with conduction oil, and the heat of generation can be passed to conduction oil rapidly, and there is not hot polymerization collection phenomenon in heater element, and heater element is guaranteed useful life.
2, heater element heats conduction oil earlier, and by heat-conducting oil heating rod shell, because the temperature of conduction oil is under control, surface temperature can not surpass conduction oil yet in air even if excellent shell exposes again, therefore can effectively avoid the generation of fire, explosion accident.
The explanation of accompanying drawing drawing:
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1, be the front view generalized section of the conduction oil electrically heated rod that the utility model proposes.
1. rod shells among the figure, 2. conduction oil, 3. dividing plate, 4. heating element, 5. oily temperature controller, 6. rod shell flange, 7. overtemperature prote switch, 8. terminal box.
Embodiment:
Among Fig. 1, heating element (4) is contained in the excellent shell (1), under the dividing plate (3).Shell flange (6) is provided with oil-in (A), oil-out (B).Conduction oil (2) is injected in the excellent shell (1) from oil-in (A), and the injection rate of conduction oil is 70%～95% of an excellent shell volume, and concrete amount can be determined according to the heating rod applying working condition.Should drain the interior air of excellent shell (1) after charging conduction oil (2) as far as possible, then oil inlet and outlet be shut.Oil temperature controller (5) be located at rod can in be used to control the conduction oil temperature.Overtemperature prote switch (7) can be located in the conduction oil, also can be located at flange and excellent shell surface is used as second class protection.The power supply lead wire of heating element (4), oily temperature controller (5), overtemperature prote switch (7) all is located in the terminal box (8).
Claims (3)
1, a kind of conduction oil electrically heated rod comprises; rod shell (1), conduction oil (2), dividing plate (3), heating element (4), oily temperature controller (5), excellent shell flange (6), overtemperature prote switch (7) terminal box (8); they interconnect and form; it is characterized in that: fill conduction oil (2) in the excellent shell (1), the injection rate of conduction oil (2) is 70%～95% of excellent shell (a 1) volume.
2, conduction oil electrically heated rod according to claim 1 is characterized in that excellent shell flange (6) is provided with heat conductive oil inlet (A).
3, conduction oil electrically heated rod according to claim 1 is characterized in that being provided with oily temperature controller (5) in the excellent shell (1), is used to control the conduction oil temperature.
