Description

Technical Field

[0001] This utility model relates to the field of lubricating oil station technology, specifically to a leak-proof sealing connection structure for lubricating oil stations. Background Technology

[0002] As a core lubrication guarantee unit for industrial equipment (such as gearboxes, bearings, and hydraulic systems), the core function of a lubricating oil station is to store, pressurize, transport, purify, cool, and recycle lubricating oil, directly affecting the operational stability and service life of downstream equipment. In industrial production scenarios, lubricating oil stations must withstand long-term conditions such as oil pressure fluctuations, equipment vibrations, and changes in ambient temperature and humidity. Therefore, the system's sealing reliability, oil supply continuity, and environmental adaptability become key indicators for evaluating its performance.

[0003] Existing publicly available technical solution CN220851680U discloses an intelligent lubricating oil pump station, including a base, an oil storage tank, and a controller. Both the oil storage tank and the controller are mounted on the base. A lubricating oil filtration assembly is installed on the base, including a spare filter mounted on the base. Each spare filter has a three-way valve at both ends, and each three-way valve has a connecting pipe at both ends. One connecting pipe connects to a supply oil filter, and the other two connecting pipes connect to a return oil filter. This application, through the coordinated use of the lubricating oil filtration assembly and monitoring assembly, utilizes an online lubricating oil monitoring instrument to monitor and control the lubricating oil filtered by the supply and return oil filters. By synchronously providing early warning signals, it facilitates timely detection and handling of lubricating oil filter malfunctions or blockages, reducing system failure risks and ensuring lubrication effectiveness.

[0004] However, when implementing existing technical solutions, the oil is prone to solidification when the outside temperature is low, which leads to increased oil pump suction resistance and may even cause the pump body to suck in air, resulting in start-up failure and seriously affecting the normal production of equipment in winter. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Given that the existing technology has the problem that the oil is prone to solidification when the outside temperature is low, which leads to an increase in the oil pump's suction resistance and may even cause the pump body to suck in air, resulting in start-up failure and seriously affecting the normal production of the equipment in winter.

[0007] To achieve the above objectives, this utility model provides the following technical solution: The anti-leakage sealing connection structure of the lubrication oil station includes: a base, an oil tank, a main oil pump, and a collector; the oil tank is located inside the base, the main oil pump is fixed to the upper end of the base by external bolts, and the collector is connected to the front oil outlet of the main oil pump. It also includes: The oil outlet assembly, the connecting assembly, and the anti-condensation assembly are provided. The oil outlet assembly is located on the front side of the collector, the connecting assembly is located at the oil outlet on the left side of the collector, and the anti-condensation assembly is installed inside the oil tank.

[0008] As a further embodiment of this utility model: the oil outlet assembly includes: a backup oil pump, a double-cylinder mesh filter, a tubular oil cooler, an oil outlet pipe, a return oil pipe, a filter pipe, and a cooling pipe; the backup oil pump is connected to the front end of the collector, and the return oil pipe is welded to the right end of the oil tank.

[0009] As a further improvement of this utility model: a filter tube is installed at the left end of the collector, and a double-cylinder mesh filter is connected to the end of the filter tube.

[0010] As a further improvement of this utility model: the oil outlet of the double-cylinder mesh filter is equipped with a cooling pipe, the end of the cooling pipe is connected to a tubular oil cooler, and the right end of the tubular oil cooler is provided with an oil outlet pipe.

[0011] As a further embodiment of this utility model: the connecting assembly includes: a first flange, a second flange, a leak-proof pipe and a sealing ring; the first flange is welded to the surface of the filter pipe.

[0012] As a further embodiment of this utility model: a leak-proof pipe is provided on one side of the first flange, and a second flange is installed on the other side of the leak-proof pipe. The first flange and the second flange are connected by external bolts; a sealing ring is installed on the surface of the leak-proof pipe.

[0013] As a further embodiment of this utility model: the anti-condensation component includes: a drive motor, a transmission belt, a stirring rod, and a stirring block; the stirring rod is connected to the inside of the oil tank via a bearing.

[0014] As a further embodiment of this utility model: a stirring block is welded to the surface of the stirring rod, a transmission belt is provided at the upper end of the stirring rod, and a drive motor is provided at the other end of the transmission belt.

[0015] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model, through the collaborative design of the connecting components, is not only used in a single part, but is systematically installed at all key connection points. By tightening bolts, the thin tubes at both ends of the leak-proof pipe are inserted into the upstream and downstream oil pipelines to form a preliminary seal. The sealing ring in the middle thick section is compressed and elastically deformed, simultaneously filling the gaps between the first flange, the second flange and the leak-proof pipe, and the leak-proof pipe and the oil pipeline. This achieves dual protection of insertion sealing and compression sealing, preventing oil leakage and avoiding environmental pollution and oil waste.

[0016] 2. This utility model connects both the main oil pump and the standby oil pump to the collector. Under normal operating conditions, the main oil pump supplies oil to the collector. In the event of a failure of the main oil pump, the standby oil pump can start immediately and continuously supply oil through the collector without interrupting system operation, effectively avoiding wear or shutdown of downstream equipment due to lack of oil. On the other hand, the oil enters the double-cylinder mesh filter through the filter pipe, and is continuously purified by the filter cylinder with one in use and one in standby. Then it is treated by the tubular oil cooler, which not only ensures the cleanliness of the oil, but also prevents high temperature from accelerating oil oxidation and extends the life of the oil and downstream equipment.

[0017] 3. This utility model effectively addresses the problem of oil solidification in low-temperature environments through its anti-condensation component. The drive motor rotates the stirring rod inside the oil tank via a transmission belt. The stirring blocks on the surface of the stirring rod continuously agitate the oil, breaking the network structure formed by paraffin crystals and dispersing precipitated additives (such as anti-wear agents and dispersants). Combined with the rotation of the stirring rod, the heat of the oil can be evenly distributed, preventing local solidification and ensuring that the oil maintains good fluidity in low-temperature environments. This ensures smooth oil intake for the main oil pump and standby oil pump, prevents pump cavitation or damage, and enables the system to operate stably under low-temperature conditions.

[0020] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0022] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0023] Example 1: Please see Figure 1 - Figure 5 This is the first embodiment of the present utility model. This embodiment provides a leak-proof sealing connection structure for a lubricating oil station, including: a base 1, an oil tank 2, a main oil pump 3, and a collector 4; the oil tank 2 is disposed inside the base 1, the main oil pump 3 is fixed to the upper end of the base 1 by external bolts, and the collector 4 is connected to the front oil outlet of the main oil pump 3, and also includes: Oil outlet assembly 5, connecting assembly 6 and anti-condensation assembly 7; oil outlet assembly 5 is located on the front side of collector 4, connecting assembly 6 is located at the oil outlet on the left side of collector 4, and anti-condensation assembly 7 is installed inside oil tank 2.

[0024] Specifically, the oil outlet assembly 5 includes: a backup oil pump 501, a double-cylinder mesh filter 502, a tubular oil cooler 503, an oil outlet pipe 504, an oil return pipe 505, a filter pipe 506, and a cooling pipe 507; the backup oil pump 501 is connected to the front end of the collector 4, and the oil return pipe 505 is welded to the right end of the oil tank 2.

[0025] Furthermore, when the main oil pump 3 fails, the standby oil pump 501 immediately starts and continuously supplies oil through the manifold 4 to avoid interruption.

[0026] Specifically, a filter tube 506 is installed at the left end of the collector 4, and a double-cylinder mesh filter 502 is connected to the end of the filter tube 506.

[0027] Furthermore, the dual-cylinder mesh filter 502 contains two independent filter cylinders, each containing a metal mesh filter element. The two cylinders are connected by a manual reversing valve at the top, forming a parallel passage with one in use and one in standby.

[0028] Specifically, the oil outlet of the dual-cylinder mesh filter 502 is equipped with a cooling pipe 507, and the end of the cooling pipe 507 is connected to a tubular oil cooler 503. An oil outlet pipe 504 is opened at the right end of the tubular oil cooler 503.

[0029] Furthermore, the shell-and-tube oil cooler 503 includes a shell, heat exchange tube bundle, tube sheet, end cap, baffle plate, and cooling water inlet and outlet. When the oil flows through the interior of the heat exchange tube bundle, the cooling water flows between the shell and the tube bundle. The heat exchange between the oil and the cooling medium is achieved through heat conduction through the tube bundle wall, thereby reducing the oil temperature and preventing high temperature from accelerating oil oxidation.

[0030] In operation, the main oil pump 3 at the top of the base 1 draws lubricating oil from the oil tank 2 through the suction pipe and delivers it to the collector 4 through the front oil outlet. The standby oil pump 501 draws oil from the oil tank 2 through another independent suction pipe, and its outlet is also connected to the front of the collector 4. When the main oil pump 3 fails, the standby oil pump 501 starts immediately, continuously supplying oil through the collector 4 to avoid interruption. The oil enters the filter pipe 506 through the oil outlet at the left end of the collector 4, and then flows into the double-cylinder mesh filter 502. After impurities are intercepted by the built-in filter screen, it is delivered to the cooling pipe 507 through its outlet, and finally enters the tube. The tubular oil cooler 503 includes a shell, heat exchange tube bundle, tube sheet, end cap, baffle plate, and cooling water inlet and outlet. When the oil flows through the heat exchange tube bundle, the cooling water flows between the shell and the tube bundle. The heat exchange between the oil and the cooling medium is achieved through heat conduction through the tube bundle wall, which lowers the oil temperature and prevents high temperature from accelerating oil oxidation. The cooled oil is transported to the lubrication point of the downstream equipment through the oil outlet pipe 504 at the right end of the tubular oil cooler 503. The lubricated oil flows back to the oil tank 2 through the return oil pipe 505 welded to the right end of the oil tank 2, completing the circulation.

[0031] In summary, this utility model connects both the main oil pump 3 and the standby oil pump 501 to the collector 4. Under normal operating conditions, the main oil pump 3 supplies oil to the collector 4. When the main oil pump 3 fails, the standby oil pump 501 can start immediately and continuously supply oil through the collector 4 without interrupting system operation, effectively avoiding wear or shutdown of downstream equipment due to lack of oil. On the other hand, the oil enters the double-cylinder mesh filter 502 through the filter pipe 506, and is continuously purified through the filter cylinder with one in use and one in standby. Then it is treated by the tubular oil cooler 503, which not only ensures the cleanliness of the oil, but also prevents high temperature from accelerating oil oxidation and extends the life of the oil and downstream equipment.

[0032] Example 2: Please see Figure 1 - Figure 5 This is the second embodiment of the present utility model.

[0033] Specifically, the connecting component 6 includes: a first flange 601, a second flange 602, a leak-proof pipe 603, and a sealing ring 604; the first flange 601 is welded to the surface of the filter pipe 506.

[0034] Furthermore, the connecting component 6 is not used in a single part, but is installed at all key connection points: the connection between the main oil pump 3 and the collector 4, the connection between the standby oil pump 501 and the collector 4, the connection between the filter pipe 506 and the double-cylinder mesh filter 502, the connection between the double-cylinder mesh filter 502 and the cooling pipe 507, the connection between the cooling pipe 507 and the tubular oil cooler 503, and the connection between the return oil pipe 505 and the oil tank 2, etc.

[0035] Specifically, a leak-proof pipe 603 is provided on one side of the first flange 601, and a second flange 602 is installed on the other side of the leak-proof pipe 603. The first flange 601 and the second flange 602 are connected by external bolts; a sealing ring 604 is installed on the surface of the leak-proof pipe 603.

[0036] Furthermore, the leak-proof pipe 603 has a stepped structure that is thin at both ends and thick in the middle. The thin pipes at both ends can be inserted into the upstream and downstream oil pipelines to form a preliminary seal, and the two ends of the thick section in the middle are engaged with the sealing ring 604.

[0037] Specifically, the anti-condensation component 7 includes: a drive motor 701, a transmission belt 702, a stirring rod 703, and a stirring block 704; the stirring rod 703 is connected to the inside of the oil tank 2 via a bearing.

[0038] Furthermore, the drive motor 701 drives the stirring rod 703 inside the oil tank 2 to rotate via the transmission belt 702.

[0039] Specifically, a stirring block 704 is welded to the surface of the stirring rod 703, a transmission belt 702 is provided at the upper end of the stirring rod 703, and a drive motor 701 is provided at the other end of the transmission belt 702.

[0040] Furthermore, the stirring block 704 continuously agitates the oil, breaking the paraffin crystal network structure and dispersing the additive precipitation.

[0041] In use, the connecting component 6 is not used in a single part, but is installed at all key connection points of the system: the connection between the main oil pump 3 and the collector 4, the connection between the standby oil pump 501 and the collector 4, the connection between the filter pipe 506 and the double-cylinder mesh filter 502, the connection between the double-cylinder mesh filter 502 and the cooling pipe 507, the connection between the cooling pipe 507 and the tubular oil cooler 503, and the connection between the return oil pipe 505 and the oil tank 2, etc. Each connection is secured with a first flange 601 and a second flange 602 by bolts. The leak-proof pipe 603 in the middle has a stepped structure that is thin at both ends and thick in the middle. The thin pipes at both ends can be inserted into the upstream and downstream oil pipelines to form a preliminary seal. The two ends of the thick section in the middle engage with the sealing ring 604. When the bolts are pre-tightened, the sealing ring 604 is compressed and elastically deformed, while filling the gaps between the flange and the leak-proof pipe 603, and between the leak-proof pipe 603 and the oil pipeline, to achieve double protection and ensure no oil leakage. In low-temperature environments, the drive motor 701 of the anti-condensation component 7 drives the stirring rod 703 inside the oil tank 2 to rotate through the transmission belt 702. The stirring blocks 704 on its surface continuously agitate the oil, breaking the paraffin crystal network structure and dispersing the additive sediment.

[0042] In summary, through the coordinated design of the connecting component 6, this utility model is not only used in a single part, but is systematically installed at all key connection points. By tightening bolts, the thin tubes at both ends of the leak-proof pipe 603 are inserted into the upstream and downstream oil pipelines to form a preliminary seal. The sealing ring 604 in the middle section is compressed and elastically deformed, simultaneously filling the gaps between the first flange 601, the second flange 602 and the leak-proof pipe 603, and between the leak-proof pipe 603 and the oil pipeline. This achieves dual protection of insertion sealing and compression sealing, preventing oil leakage and avoiding environmental pollution and oil waste. This invention effectively addresses the problem of oil solidification in low-temperature environments through the anti-condensation component 7. The drive motor 701 drives the stirring rod 703 inside the oil tank 2 to rotate via the transmission belt 702. The stirring blocks 704 on the surface of the stirring rod 703 continuously agitate the oil, breaking the network structure formed by paraffin crystals and dispersing precipitated additives such as anti-wear agents and dispersants. Combined with the rotation of the stirring rod 703, the heat of the oil can be evenly distributed, preventing local solidification and ensuring that the oil maintains good fluidity in low-temperature environments. This ensures smooth oil intake for the main oil pump 3 and the standby oil pump 501, prevents pump cavitation or damage, and enables the system to operate stably under low-temperature conditions.
