[0002] Heavy oil, due to its high asphalt content and low wax content, has high viscosity, poor flow, and is extremely challenging to extract. To address the numerous challenges encountered in the extraction of "three-high" crude oil, such as difficulty in lifting the oil, excessive load on the sucker rod, difficulty in lowering the oil, and increased pumping unit load, heavy oil electric heating devices are required. These devices utilize the heat energy generated by electrical heating to heat the oil throughout the pipeline, improving its fluidity.

[0003] An existing patent (application number: CN212628441U) proposes a novel energy-saving and environmentally friendly heavy oil electric heating device, comprising a heating system and an intelligent control system. The heating system is equipped with an electric heating tungsten filament and a stainless steel pipe sleeve, and is connected to a heavy oil heating inlet and a heavy oil heating outlet. The heavy oil heating inlet is connected to a heavy oil pipeline access port via a heavy oil inlet pipeline, and the heavy oil heating outlet is connected to a heavy oil pipeline access port via a heavy oil outlet pipeline. The heating system is centrally and automatically controlled by the intelligent control system, and the heating system heats the incoming heavy oil into a thin or transportable state.

[0004] There are impurities and particulate matter in heavy oil, and directly heating it may cause damage to the equipment. In addition, the above-mentioned heavy oil electric heating device uses electric heating tungsten filament for heating. It may suffer from wear and breakage when working in a high-temperature environment for a long time, and requires regular maintenance and replacement, so it has certain limitations.

[0038] In the present invention, by adopting the above-mentioned design, after the thick oil enters the filter block 2 through the oil inlet pipe 1, it will first contact the drawer 202, and then enter the through groove after being filtered by the filter mesh 203 to be heated, so that the mixed impurities and large particles therein are retained in the drawer 202 and will not follow it into the heating box 4 to cause damage to the heating box 4. By rotating the positioning rod 302, the positioning rod 302 is no longer limited by the positioning groove 303, the drawer 202 is removed from the filter block 2, and the impurities and large particles in the drawer 202 are regularly cleaned.

[0039] Furthermore, as a specific embodiment of the present invention, the present invention provides a thick oil electric heating device with a filtering function.

[0040] Specifically, such as Figure 4 As shown, a rotating plate 304 is provided on the positioning block 3, a positioning cavity 301 is opened in the positioning block 3, a torsion spring 305 is provided in the positioning cavity 301, and two ends of the torsion spring 305 are fixedly connected to the positioning cavity 301 and the positioning rod 302 respectively.

[0041] When the filter block 2 is installed, the end of the positioning rod 302 is converted to a vertical state by rotating the rotating plate 304, and then the positioning rod 302 is released after the end of the positioning rod 302 is inserted into the positioning groove 303. When the end of the positioning rod 302 moves to the end of the positioning groove 303, the torsion spring 305 drives the positioning rod 302 to rotate so that its end is engaged with the positioning groove 303, so that the drawer 202 is fixed on the filter block 2.

[0042] Furthermore, as a specific embodiment of the present invention, the present invention provides a thick oil electric heating device with a filtering function.

[0043] Specifically, such as Figure 3 As shown, the filter 203 is slidably plugged into the drawer 202 , and the bottom surface of the drawer 202 is tilted, with its lowest end located at the plugging position of the filter 203 .

[0044] In the present invention, by adopting the above-mentioned design, the filter 203 can be removed from the drawer 202 separately for flushing and replacement while the drawer 202 is removed, which further facilitates subsequent maintenance and ensures that no thick oil will remain in the drawer 202 when the drawer 202 is taken out.

During the swirling period, the heavy oil is heated by the PTC heating element 403, thereby improving the fluidity of the heavy oil. In addition, the PTC heating element 403 has low thermal resistance, high heat exchange efficiency, constant temperature, energy saving, and good safety performance. Under any application situation, the surface "reddening" phenomenon of electric heating tube heaters will not occur, and there will be no safety hazards such as burns and fire.

[0056] In the present invention, by adopting the above-mentioned design, the temperature sensor 501 can detect the temperature in the heating chamber 401 and transmit its temperature information in real time to the control panel 5 arranged on one side of the heating box 4, so that the staff can directly observe the temperature in the heating box 4 through the control panel 5, thereby better regulating the power of the PTC heating element 403, further improving the safety of the device.

[0057] Furthermore, as a specific embodiment of the present invention, the present invention provides a thick oil electric heating device with a filtering function.

[0058] Specifically, such as Figure 1 As shown, an antenna 502 is provided on the top of the control panel 5 .

[0059] In the present invention, by adopting the above-mentioned design, the antenna 502 can transmit the information collected in the control panel 5 to the staff through the Internet, so that the staff can remotely monitor the operation of the device.

[0060] Working principle: When in use, the thick oil will enter the filter block 2 from the oil inlet pipe 1 and then enter the drawer 202. After being filtered by the filter screen 203, it will enter the coil 402 through the through slot, and will be sent out from the heating box 4 after circling for several circles. It will be heated by the PTC heater 403 while circling to improve its fluidity. When performing inspection and maintenance, the drawer 202 can be quickly removed from the filter block 2 by rotating the rotating plate 304, and the impurities and large particles therein can be centrally processed. The filter screen 203 can be removed from the drawer 202 separately for cleaning. The inspection door 404 can be opened by pulling the handrail 405 to quickly inspect and maintain the coil 402 and the PTC heater 403.
