The utility model discloses the during operation, pack into the medium in to the heating chamber, control electric heating rod work, heat, high temperature medium after the heating passes through heat exchanger and crude oil heat transfer, make the crude oil temperature rise, and carry out the circulation flow of medium through the circulating pump, temperature sensor carries out the detection of liquid temperature in the pipeline, when liquid temperature is less than the setting value in the pipeline, heating structure begins work, when the temperature reaches the setting value in the pipeline, then heating structure stop work, and measure the liquid level through level sensor and change. Compared with the prior art, the beneficial effects of the utility model reside in that: the device simple to operate is convenient for remove, heats defeated crude oil of pipe to the temperature of leaving a station that requires, guarantees that the crude oil temperature is above the crude oil condensation point all the time in the pipe to make its carry smoothly, improve the outer defeated oil temperature of transfer station, reduce defeated oil main line back pressure, prevent that the pipeline from blockking up, guarantee crude oil production.

For the heating is more convenient and flexible, four electric heating rods are fixed, and the electric heating rods are symmetrically arranged on the side wall of the heating chamber in pairs.

In order to ensure that the liquid level meter measures accurately and effectively for a long time and prevent the periphery of the cable from being corroded, the periphery of the cable of the liquid level sensor is sleeved with a protective sleeve.

In order to reduce heat loss in the transmission process, the surface of the pipeline is wrapped with heat insulation cotton.

In order to prevent the electric heating rod from causing electric leakage after being damaged and measuring the power consumption loss, an electric leakage protection device and an electric meter are installed in the control room.

In order to guarantee that the electric heating rod can work safely and normally, a safety protection cover is arranged outside the electric heating rod on the side wall of the heating chamber, and the design can realize rain prevention.
