[0015] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention. Example 1:

[0016] Please refer to Figures 1-2 A mobile oil storage tank water circulation heating device, comprising: The mobile carrier, comprising a trailer body 1, serves as the foundation for the entire device, possessing excellent mobility and stability. Both sides of the trailer body 1 are rotatably connected to moving wheels 2, which are made of high-strength, wear-resistant material to ensure smooth movement on various terrains and provide shock absorption, reducing impact on internal components during movement. A hook handle 3 is located at the front of the trailer body 1 for easy towing by operators. The lower front of the trailer body 1 features foldable support legs 4; these legs can be lowered after the device is in position, effectively increasing stability and preventing shaking or displacement during heating. Protective frames 5 are fixedly connected to the upper sides and front of the trailer body 1. These frames are made of high-strength metal, providing impact resistance and protecting internal components such as the heating unit and circulation assembly from external collisions. The heating unit and circulation assembly are located inside the protective frames 5.

[0017] The heating unit includes a heating chamber 6, with a 30KW electric heating element installed inside. This element offers advantages such as high heating efficiency, uniform heating, and long service life. A temperature controller is also included for precise temperature control, allowing for different temperature ranges to be set according to actual needs, ensuring a stable and reliable heating process. An insulation layer is installed on the outside of the heating chamber 6 to prevent heat loss. The sides of the heating chamber 6 are equipped with a level gauge 12, a pressure gauge 13, and a fluid exchange seat 15. An automatic pressure relief valve 14 is located on the top of the heating chamber 6. The level gauge 12 displays the real-time level of the heat transfer medium inside the heating chamber 6, allowing operators to easily monitor the medium level and prevent insufficient medium from affecting the heating effect. The pressure gauge 13 monitors the pressure inside the heating chamber 6, ensuring the heating process operates within a safe pressure range. The automatic pressure relief valve 14 automatically opens when the pressure inside the heating chamber 6 exceeds a set value, releasing excess pressure and ensuring safe operation of the device. The fluid exchange seat 15 facilitates the replacement of the heat transfer medium inside the heating chamber 6 when needed.

[0018] The circulation assembly includes an explosion-proof 4KW hot water circulation pump 7, a first circulation pipe 8, and a second circulation pipe 9. One working end of the hot water circulation pump 7 is connected to the interior of the heating box 6, and the other working end is connected to the first circulation pipe 8. A heat exchange coil 10 is connected to the end of the first circulation pipe 8 furthest from the hot water circulation pump 7. The heat exchange coil 10 is made of corrosion-resistant stainless steel, possessing excellent corrosion resistance and adaptable to the requirements of different heat transfer media. The diameter of the heat exchange coil 10 is compatible with the inlet of the oil storage tank, ensuring smooth connection to the oil storage tank. One end of the second circulation pipe 9 is connected to the interior of the heating box 6, and the other end is connected to the heat exchange coil 10, forming a complete circulation loop.

[0019] The explosion-proof electrical component 11 is fixed to the mobile carrier by a bracket. The heating unit, its matching temperature controller, and circulation assembly are all electrically connected to the explosion-proof electrical component 11. The explosion-proof electrical component 11 adopts an explosion-proof design, and the electrical junction box is sealed to effectively prevent the ingress of external dust, moisture, etc., ensuring the normal operation of the electrical component. Simultaneously, it is equipped with an explosion-proof leakage current protector, which can quickly cut off the power supply in the event of leakage or other abnormalities, ensuring the personal safety of the operators.

[0020] Working principle: Move the device to the side of the oil storage tank, connect the heat exchange coil 10 to the oil storage tank, and inject the heat transfer medium water or antifreeze; start the explosion-proof hot water circulation pump 7 to drive the medium to circulate between the heating unit and the heat exchange coil 10; the electric heating tube heats the medium, which is then transported to the heat exchange coil 10 inside the tank by the hot water circulation pump 7. Indirect heating of the material in the oil storage tank is achieved through heat conduction. The temperature controller monitors the medium temperature in real time to ensure that the heating temperature is stable within the set range. Example 2:

[0021] The mobile oil storage tank water circulation heating device provided in Embodiment 1 is further optimized, specifically, as follows: Figures 3-4 As shown, it also includes a storage rack, which is located above the trailer body 1 and inside the protective frame 5. It is used to store the first circulation pipe 8 and the second circulation pipe 9, so that the pipes are arranged more neatly and orderly when the device is not in use, avoiding the pipes from being messy and tangled and affecting the next use. It is also convenient for transportation and storage.

[0022] Specifically, the storage rack includes two vertically arranged uprights 16. The uprights 16 are made of high-strength metal and have a certain load-bearing capacity. The uprights 16 are fixedly connected to the trailer body 1 and the protective frame 5, ensuring the stability of the storage rack. Brackets 17 are fixedly connected to the sides of the uprights 16. The brackets 17 have an arc-shaped design, adapted to the shape of the first circulation pipe 8 and the second circulation pipe 9. The first circulation pipe 8 and the second circulation pipe 9 can be placed inside the brackets 17, providing good support and fixation. The bottoms of the two uprights 16 are connected and fixed by a horizontal connecting bracket 18, further enhancing the overall structural strength of the storage rack.

[0023] Furthermore, the storage rack also includes a limiting frame 19, which is arranged in an inverted U-shape. One side of the limiting frame 19 is vertically connected to the connecting frame 18 and the protective frame 5, and the bottom of both sides of the limiting frame 19 is vertically connected to the trailer body 1. This plug-in connection method facilitates the installation and removal of the limiting frame 19. When it is necessary to place or remove the first circulation pipe 8 or the second circulation pipe 9, the limiting frame 19 can be removed, making the operation more convenient. After the pipeline is placed, the limiting frame 19 is installed, which can further limit the pipeline and prevent the pipeline from shaking or falling off during the movement of the device.
