Description

Technical Field

[0001] The present invention relates to the oil quality detection technology of vacuum oil filters, and particularly to a vacuum oil filter for real-time monitoring of oil quality. Background Art

[0002] A vacuum oil filter is a device used to remove impurities in oil, which can effectively remove moisture, gas and solid particles in the oil, improve the cleanliness of the oil, and is commonly used in industries such as electric power and mechanical manufacturing. During use, operators need to make certain adjustments to the oil filter according to the current impurity content of the oil, so that the oil filter can obtain the best working state and enable the operators to understand the current oil condition.

[0003] Most of the existing oil quality detections directly set monitoring devices such as gas content meters and particle size meters in the oil transmission pipeline. However, this monitoring method has a single function, and the monitoring process requires operators to arrive at the site to obtain monitoring data, and the intelligent efficiency is poor. The oil will pass through multiple devices during the filtration process, so the flow rate of the oil may change due to the influence of the devices, and this change will also cause misjudgment of the monitoring device, affecting the actual monitoring effect. Summary of the Invention

[0004] In order to make up for the deficiencies of the existing technology problems, the purpose of the present invention is to solve the problems existing in the prior art: monitoring devices such as gas content meters and particle size meters may produce misjudgments due to changes in the oil flow rate during the monitoring process, resulting in incorrect monitoring results, and operators are also required to arrive at the site for correction, which is inconvenient, has poor work efficiency, and low monitoring accuracy.

[0005] To solve the existing technical problems, the technical solution of the present invention is as follows: It includes an oil inlet pipeline, an oil discharge pipeline, and a degassing cylinder arranged between the oil inlet pipeline and the oil discharge pipeline. The oil inlet pipeline is successively provided with a manual ball valve, a coarse filter, an oil inlet pump, a manual ball valve, a flow meter, a plate heat exchanger, a heating component, a temperature probe, a pressure probe, a regeneration valve, a primary filter component, and a manual ball valve at the output end of the primary filter component along the input end to the output end, and the output end of the oil inlet pipeline is directly connected to the oil inlet port of the degassing cylinder through a manual ball valve; The oil discharge port of the degassing cylinder is directly connected to the oil discharge pipeline, and a foam probe and a float level transmitter are arranged inside the degassing cylinder. The degassing cylinder is connected with an on-line gas content monitoring component through a pipeline. The oil discharge pipeline is successively provided with an oil discharge pump, an electric control valve, a one-way valve, a secondary filter component, a particle size monitoring component, a manual ball valve, and a manual ball valve at the output end of the oil discharge pipeline from the input end to the output end; An exhaust pipe line is arranged in the degassing cylinder. The exhaust pipe line is sequentially provided with a manual butterfly valve, a vacuum probe, a separator, a vacuum pressure gauge arranged in the separator, a Roots pump, a condenser, an electric ball valve arranged in the condenser, an electric ball valve, a vacuum rotary vane pump and a smoke exhaust condenser from the input end to the output end.

[0006] Further, a branch pipe parallel to the oil inlet pipe is arranged on one side of the oil inlet pipe close to the input end. A branch pipe parallel to the oil inlet pipe is arranged near the input end of the oil inlet pipe, and a manual ball valve is arranged at the end of the branch pipe. Such a design allows bypass control of the oil flow. A manual ball valve is arranged at the end of the branch pipe, and a branch pipe is arranged in the part of the oil inlet pipe between the filter assembly and the manual ball valve, so that selection or flow balancing can be carried out between the primary filter assembly and the secondary filter assembly to optimize the filtering effect. The branch pipe extends and communicates between the check valve of the oil discharge pipe and the secondary filter assembly, and a manual ball valve is arranged at the middle position of the branch pipe here, which can accurately control the direction and flow of the oil flow.

[0007] Further, a branch pipe is arranged at the position between the particle size monitoring assembly and the manual ball valve on the oil inlet pipe, and the branch pipe is respectively communicated with the electric ball valves in the degassing cylinder and the condenser, providing a branch path for the oil flow to achieve more refined control during the oil quality monitoring and treatment process, ensuring the accuracy of the oil quality monitoring and the effective operation of the filtering system.

[0008] Further, a branch pipe with a manual ball valve is directly connected between the oil inlet pipe and the oil discharge pipe, and a branch pipe connecting to the output end side of the manual ball valve on the surface of the oil discharge pipe is arranged at the output end of the manual ball valve on the surface of the oil inlet pipe, and a branch pipe connecting to the output end of the manual ball valve on the surface of the oil inlet pipe is arranged at the input end of the manual ball valve on the surface of the oil discharge pipe, increasing the multi-path selection of the oil circuit, improving the reliability of the system, and reducing the shutdown risk caused by a single-path failure.

[0009] Further, a pipe connected to the electric ball valve is arranged in the degassing cylinder, and the pipe is simultaneously connected between the particle size monitoring assembly and the manual ball valve on the surface of the oil discharge pipe, and a manual ball valve is arranged at one end of the pipe close to the oil discharge pipe. Degassing, particle size monitoring and flow control are realized through the manual ball valve and the branch pipe, increasing the operation flexibility, safety and reliability of the system, and ensuring the high efficiency and stability of the oil treatment.

[0010] Further, a vacuum probe is provided inside the on-line gas content monitoring component, and the on-line gas content monitoring component extends out a branch pipe. The branch pipes are respectively connected between the oil discharge pump and the electric control valve of the oil discharge pipeline, and between the manual ball valve and the flow meter of the oil inlet pipeline. Manual ball valves are respectively arranged at one ends of the branch pipes close to the oil inlet pipeline and the oil discharge pipeline. The gas content of the oil fluid is monitored in real time through the on-line gas content monitoring component and the vacuum probe, and precise control of the oil inlet and oil discharge pipelines is achieved through the branch pipes, the manual ball valves, and the manual ball valves, ensuring the flow rate and quality of the oil fluid, thereby maintaining the normal operation of the system and the oil fluid treatment efficiency.

[0011] Further, manual ball valves are respectively arranged at the input end and the output end of the regeneration valve. A communication pipeline is arranged at the output ends of the manual ball valves and the manual ball valves, providing flexible fluid control, facilitating system maintenance, and ensuring operation safety.

[0012] Further, the above structures are all electrically connected to the PLC control system in the oil filter electric control cabinet, and a frequency converter is arranged at the connection port of the PLC control system. The overall structure can be remotely monitored and remotely controlled through the PLC.

[0013] Compared with the prior art, the advantages of the present invention are as follows: The present invention first conveys the oil fluid to the degassing cylinder through the oil inlet pipeline. During the conveying process, the oil fluid continuously passes through various components and is initially filtered by the primary filtration component to reduce impurities in the oil fluid. The oil fluid entering the degassing cylinder will further remove gas impurities in the oil fluid and contact the on-line gas content monitoring component for gas content detection. Subsequently, the oil fluid passes through various structures of the oil discharge pipeline and enters the secondary filtration component for secondary filtration. The oil fluid that has completed secondary filtration will also be monitored for particle size by the particle size monitoring component and continue to flow out along the oil discharge pipeline. In the overall process, no manual operation by the operator is required. It can meet the remote monitoring and operation of the operator while solving the monitoring of the gas content, water content, and particle size in the oil fluid. And through the branch pipe arranged between the oil inlet pipeline and the oil discharge pipeline, and the PLC remote control, the automatic flow balance between the oil inlet pipeline and the oil discharge pipeline is completed.

[0020] Principle of operation: First, the present invention conveys oil through the oil inlet pipeline 1 by the oil inlet pump 003 in the direction of the degassing cylinder 015. During the flow of the oil, it passes through the flowmeter 005. The flowmeter 005 monitors and transmits the oil flow signal into the PLC. The PLC controls the oil discharge pump and the oil inlet pump through the frequency converter to balance the current oil flow, and automatic control can be completed through the PLC; When the oil enters the degassing cylinder 015 through the oil inlet pipeline 1, it enters the primary filtration assembly 012, where it is filtered once to remove internal impurities. Subsequently, the oil enters the degassing cylinder 015, where gas impurities and moisture are separated. During this process, the online gas content monitoring assembly 018 monitors the gas content in the current oil. Then, the oil leaves the degassing cylinder 015 along the oil discharge pipeline 2. In the oil discharge pipeline 2, the oil receives the power of the oil discharge pump 019 to ensure smooth movement and is filtered a second time through the secondary filtration assembly 023. Subsequently, the oil that has undergone secondary filtration and treatment in the degassing cylinder 015 enters the particle size monitoring assembly 025 to monitor the impurity content in the current oil. Moreover, the online gas content monitoring assembly 019 and the particle size monitoring assembly 025 transmit the monitoring information into the PLC, and the operator can remotely view and analyze the operation data through the data displayed on the PLC.

[0022] The above structures are all electrically connected to the PLC control system in the electrical control cabinet of the oil filter, and a frequency converter is provided at the connection port of the PLC control system.

[0023] Description of working principle: First, the oil in the degassing cylinder 015 is processed, and the gas and part of the liquid contained in the oil are separated. The separated gas enters the exhaust pipe 3 and undergoes gas-liquid separation through the separator 104. At this time, the liquid can be directly discharged outwards, and the gas continues to move under the action of the vacuum rotary vane pump 100 at the end of the exhaust pipe 3 and passes through the Roots pump 103 and the condenser 102 and enters the exhaust condenser 150 for gas-liquid separation again, and finally the gas is discharged.
