Description

Technical Field

[0001] This utility model relates to the field of heating equipment technology, and in particular to a safe oil heater. Background Technology

[0002] Currently, in crude oil production, crude oil extracted from underground must be transported through pipelines. Due to the high viscosity of crude oil, it often solidifies during transportation, preventing it from being discharged smoothly. Therefore, it is necessary to heat the crude oil. Electric heating is commonly used to heat the crude oil pipelines to reduce the viscosity of the liquid, making it easier to transport and move. This electric heating method usually uses electric heating rods to directly heat the pipeline, which poses significant safety hazards. The main issues are that the temperature of the electric heating rods can become too high during the electric heating process, and the temperature is difficult to control, easily causing localized high or low temperatures. If not properly controlled, this can lead to safety accidents such as pipe bursts and coking. Utility Model Content

[0005] According to another embodiment of the present invention, the outer shell is further provided with a support base on the bottom surface, and the support point is provided with an anti-slip pad on the bottom surface.

[0006] According to another embodiment of the present invention, a check valve is provided on the oil inlet and a solenoid valve is provided on the oil outlet.

[0007] According to another embodiment of the present invention, the first baffle and the second baffle are further offset.

[0008] According to another embodiment of the present invention, a compensation gasket is further provided between the mounting part and the outer casing.

[0009] According to another embodiment of the present invention, a temperature sensor is further provided on the right side of the inner wall of the outer casing, and the temperature sensor is located near the oil outlet.

[0010] According to another embodiment of the present invention, the outer shell further includes, from the outside to the inside, an anti-corrosion layer, a base layer, a thermal insulation layer, and a protective layer.

[0011] According to another embodiment of the present invention, a drain outlet is further disposed between the support bases.

[0012] The beneficial effects of this utility model are: by setting an inner shell inside the outer shell, the heating tube is built inside to avoid direct contact with oil, thus preventing local high or low temperatures, as well as safety accidents such as tube bursting and coking. The inner shell can increase the contact area with oil, thereby improving heating efficiency and heating uniformity. Attached Figure Description

[0017] like Figure 1 This is a schematic diagram of the structure of this utility model, a safety oil heater, including a shell 1. The shell 1 has an oil inlet 2 on its left side, an oil outlet 3 on its right side, and a drain outlet 4 at its bottom. An inner shell 5 is located inside the shell 1. A tube plate 7 for fixing a heating tube 6 is located on the left side of the inner shell 5. A heat-conducting liquid 8 is placed inside the inner shell 5. A mounting part 9 is located on the left side of the inner shell 5 and is connected to the shell 1 by bolts. A first baffle 10 is provided on the inner wall of the shell 1, and a second baffle 11 is provided on the outer wall of the inner shell 5. This utility model, by placing the heating tube 6 inside the shell 1 within the inner shell 1, avoids direct contact with the oil, preventing localized high or low temperatures, tube bursts, coking, and other safety accidents. The inner shell 5 increases the contact area with the oil, improving heating efficiency and uniform heating.

[0018] The bottom surface of the outer shell 1 is provided with a support base 12, and the bottom surface of the support point is provided with an anti-slip pad 13. A temperature sensor 16 is provided on the right side of the inner wall of the outer shell 1, and the temperature sensor 16 is located near the oil outlet 3. The outer shell 1 includes, from the outside to the inside, an anti-corrosion layer 17, a base layer 18, a heat insulation layer 19, and a protective layer 20.

[0019] A check valve 14 is provided on the oil inlet 2, and a solenoid valve 15 is provided on the oil outlet 3.

[0020] The first baffle plate 10 and the second baffle plate 11 are offset from each other, a compensation gasket is provided between the mounting part 9 and the outer shell 1, and the drain port 4 is provided between the support bases 12.

[0021] Example: When in use, connect to an external power source and control the heating element 6 to heat the heat transfer fluid 8 filled in the inner shell 5. When the heat transfer fluid temperature rises to 100°C, oil is introduced through the oil inlet 8. The temperature sensor 16 determines whether the oil temperature has been heated to the specified value. When the specified value is reached, the solenoid valve 15 opens; otherwise, the solenoid valve 15 can be closed.
