Technical Field

[0001] This utility model relates to the field of oil detection and filtration technology, and in particular to an intelligent online oil filtration system. Background Technology

[0002] Tunnel boring machines (TBMs) are the main construction machinery used in underground tunneling projects, and they are widely used in large-scale tunnel projects such as urban subways, river-crossing highway tunnels, and sea-crossing tunnels in my country. The analysis and treatment of the lubricating fluid in TBMs is crucial. Problems with the system can lead to significant issues such as increased costs and risks for both the TBM and the entire project. Therefore, it is essential to monitor key lubricating fluid parameters and address them promptly during TBM construction.

[0003] Numerous studies have been conducted on the management of tunnel boring machine lubrication systems, with most suggesting the use of offline or online monitoring to track oil levels and analyze oil quality and system wear. However, once a problem is detected, the system must be shut down for manual handling. While this ensures the accuracy of the test results, the testing cycle is relatively long and lacks timeliness.

[0004] How to design an ingenious, simple, and intelligent online oil treatment system that can detect system problems in real time by monitoring indicators such as oil viscosity, moisture, and contamination, and automatically and specifically address them to ensure that the oil used by the equipment meets the usage requirements, is a technical problem that needs to be solved in the existing technology. Utility Model Content

[0005] To address the aforementioned technical problems in existing shield machine oil circulation systems, this invention provides an intelligent online oil filtration system. This system features a clever design and simple structure, enabling intelligent oil treatment. By real-time monitoring of oil viscosity, moisture content, and contamination levels, it promptly identifies system problems and automatically addresses them accordingly. This ensures that the oil used by the equipment meets operational requirements, achieving real-time oil monitoring and intelligent online problem-solving.

[0006] The technical solution adopted by this utility model to solve the above-mentioned technical problems is: an intelligent online oil filtration system. The system is installed on the top of the main oil tank. The system includes a main return oil pipeline, a small pump, a suction pump, an online oil detection module, an oil filtration module, a communication control module, and a host computer. The online oil detection module and the oil filtration module are connected in parallel. The online oil detection module and the small pump are connected in series in the first loop formed by the main return oil pipeline and the main oil tank. The oil filtration module and the suction pump are connected in series in the second loop formed by the main return oil pipeline and the main oil tank. The online oil detection module sends the oil data detected on the main return oil pipeline to the communication control module and displays it on the host computer. The system controls the start and stop of the suction pump according to the set detection data. The oil filtration module starts filtering and returns the filtered qualified oil to the main oil tank.

[0007] As a further optimization of the above-mentioned intelligent online oil filtration system, the online oil detection module includes a pressure transmitter, a viscosity sensor, a moisture sensor, and a particle counter. The pressure transmitter, viscosity sensor, moisture sensor, and particle counter are arranged in sequence and connected in series with a small pump in the first circuit.

[0008] As a further optimization of the aforementioned intelligent online oil filtration system, the oil filtration module includes a magnetic filter and a centrifugal oil filter.

[0009] As a further optimization of the aforementioned intelligent online oil filtration system, multiple control ball valves are also installed on the first and second circuits.

[0010] Compared with the prior art, the beneficial effects of this utility model are: First, this utility model's filtration system combines real-time oil monitoring technology and centrifugal oil filtration technology, while avoiding the problems of traditional circulating filtration systems' inability to achieve automatic detection and incomplete oil filtration. This utility model is low-cost, highly operable, and easy to implement. The system is installed near the oil tank of the oil circulation system, and the overall structure is fixed by fastening bolts. A hollow rotating shaft completes dynamic balance testing, ensuring stability even when the centrifugal oil filtration system is running at high speed. Specifically, this invention has the following advantages: 1. By combining real-time oil monitoring technology with centrifugal filtration technology, wear and tear on key components of mechanical equipment can be avoided due to untimely detection of oil performance status and incomplete oil filtration.

[0011] 2. Control the start and stop of the oil pump based on the oil level detection data to prevent the oil pump from working for a long time and affecting its service life.

[0012] 3. Direct economic benefits: Extends the service life of oil by about 2 times; extends the service life of online filter elements by more than 5 times.

The online oil detection module and the oil filtration module are connected in parallel, and the online oil detection module and the small pump 2 are connected in series in the first loop formed by the main return oil pipeline 1 and the main oil tank 5. The oil filtration module and the suction pump 3 are connected in series in the second loop formed by the main return oil pipeline 1 and the main oil tank 5. The online oil detection module sends the oil data detected on the main return oil pipeline 1 to the communication control module and displays it on the host computer 4. Based on the set detection data, the system controls the start and stop of the suction pump 3. The oil filtration module starts filtering and returns the filtered qualified oil to the main oil tank 5.

[0017] The online oil detection module includes a pressure transmitter 6, a viscosity sensor 7, a moisture sensor 8, and a particle counter 9.

[0022] 3. After the system power is turned on, the oil flows through the online oil detection module. The online oil detection module transmits the detection data to the host computer 4 via the communication control module. The communication control module controls the start and stop of the oil pump 3 according to the detection data. If the oil detection data is unqualified, the oil pump 3 can send the high-pressure oil to the centrifugal oil filter 11 when it starts. The centrifugal oil filter 11 returns the filtered oil to the main oil tank 5.

[0023] 4. The hydraulic fluid in the hydraulic system is repeatedly filtered until the oil monitoring parameters reach the qualified standard.

[0024] In practical applications, all pipelines between the oil inlet and outlet ports of the online oil monitoring module are connected using stainless steel pipes. These pipes are flexible, corrosion-resistant, and have good thermal conductivity. Quick-connect fittings are used at the oil inlet and outlet ports for easy and quick assembly and disassembly of the pipelines.

[0025] The centrifugal filter features a removable top cover and rotating drum, allowing maintenance personnel to easily disassemble and clean the internal oil and water.

[0026] A magnetic filter is connected in series at the oil inlet to ensure that metal particles and larger particles inside the oil do not enter the centrifugal filter and cause serious wear to its internal structure.

[0027] This utility model features an ingenious design and simple structure, enabling an intelligent oil handling system. By monitoring indicators such as oil viscosity, moisture content, and contamination levels in real time, it can promptly identify system problems and automatically address them accordingly. This ensures that the oil used in the equipment meets operational requirements.
