Description

Technical Field

[0001] The utility model relates to the technical field of heating equipment, in particular to a heating equipment which is convenient for replacing a heating tube. Background Art

[0002] The vacuum oil filter is a device used to remove impurities, moisture and gas from oil. Its working principle is to extract the oil in the oil tank through negative pressure and filter the oil through the filter element to achieve the purpose of removing impurities and moisture. In this process, due to the high viscosity of the oil, the filtering efficiency of the filter element is greatly affected. At this time, electric heating can play an important role. Electric heating can speed up the temperature of the oil and reduce its viscosity, thereby achieving a better filtering effect.

[0003] Conventional vacuum oil filter equipment uses electric heaters to directly heat the oil. However, for oils with high requirements, direct heating may cause the oil to be instantly heated when it contacts the heating surface, resulting in carbon deposits and causing problems with the quality of the oil. In addition, the heating tubes are mostly fixed and not easy to replace.

[0004] Therefore, how to provide a heating device that can indirectly heat and facilitate the replacement of the heating tube has become a technical problem to be solved by those skilled in the art. Utility Model Content

[0007] The shell adopts the existing double-layer insulation structure on the market, which makes the shell have good insulation effect. The base plays a role of fixed support for the shell. The heating component is arranged inside the base. The heat energy generated by its operation indirectly heats the oil inside the shell. In this way, carbon deposits on the oil are avoided during heating, thereby ensuring the quality of the oil. The snap-on disassembly and connection design makes it convenient for the staff to replace and maintain the heating pipe at a later time.

[0008] Preferably, an oil inlet pipe is provided on one side of the shell, and an oil outlet pipe is provided on the other side, and the installation height of the oil outlet pipe is higher than the installation height of the oil inlet pipe.

[0018] Preferably, the safety component includes a pressure gauge and a pressure relief valve, and the pressure gauge and the pressure relief valve are installed on the top of the upper cover plate.

[0019] The pressure gauge and the pressure relief valve adopt the existing structure on the market. The pressure gauge is used to detect the pressure inside the shell. The pressure relief valve can automatically open when the upper limit of the safety pressure is reached to reduce the pressure to ensure safety.

[0020] The beneficial effects of the utility model are:
