Technical Field

[0001] This utility model relates to the field of heat transfer oil filtration systems, specifically a heat transfer oil filtration system. Background Technology

[0002] The heat transfer oil filtration system is used to filter the heat transfer oil. Heat transfer oil filtration is a key measure to ensure stable operation of the system and extend its service life. Its core is to remove impurities through physical filtration, while combining online cleaning technology to optimize oil indicators. For example, the authorized patent with publication number CN221771749U (Heat Transfer Oil Filtration System) includes an oil injection pump and an oil filter connected in parallel with the oil injection pump. The oil injection pump is installed on the heat transfer oil supply pipeline, and the oil filter is installed on the heat transfer oil bypass filtration pipeline. The input end of the heat transfer oil bypass filtration pipeline is connected to the output end of the oil injection pump, and the output end of the heat transfer oil bypass filtration pipeline is connected to the input end of the oil injection pump. The advantages of this utility model are: simple structure, convenient operation, no need for operators to constantly monitor liquid level and oil temperature changes. Without changing the original heat transfer oil pipeline system, only a bypass filter needs to be installed at both ends of the oil injection pump. Utilizing the pressure difference between the inlet and outlet of the oil filter, impurities in the heat transfer oil can be automatically filtered while the system is running, thereby improving the quality of the heat transfer oil and reducing the wear of the seals in the heat transfer oil system caused by impurities in the heat transfer oil. The existing thermal oil filtration system described above is a split type, which is not convenient to connect and control. It cannot assemble and use coarse and fine filters, making filtration control inconvenient. The waste residue generated during the filtration process cannot be automatically discharged and needs to be disassembled and cleaned, which makes its continuous use capacity insufficient.
