[0001] This invention relates to the field of lubricating oil filtration technology, and in particular to a lubricating oil cross-flow filtration device for main engines. Background Technology

[0002] Oil filling in ship pipelines, also known as oil filling in ship pipelines, is an essential procedure during ship construction before main engine commissioning. It involves flushing the pipelines with liquid lubricating oil to remove impurities from the pipelines, thus meeting the operational requirements of the main engine's various mechanisms and equipment.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0026] Please see the appendix Figure 1-4 A lubricating oil filter device for main engine, comprising:

[0027] The oil tank section 1 includes a tank body 10, a heating tube 11, an oil quantity control component 12, and a counterweight component 13. The tank body 10 is provided with an oil inlet 100 and an oil outlet 101, and a partition 104 is provided in the middle of the tank body 10 to divide it into a heating chamber 102 and an oil outlet chamber 103. The heating tube 11 is located in the heating chamber 102. The oil quantity control component 12 is fixedly connected to the partition 104. The counterweight component 13 is located in the oil outlet chamber 103 and is fixedly connected to the oil quantity control component 12.

[0028] The filter section 2 includes a U-shaped bend 20, a coarse filter assembly 21, a filter box 22, and a fine filter assembly 23. One end of the U-shaped bend 20 is detachably connected to the oil inlet 100 via two sets of symmetrically positioned connecting assemblies 24, and the other end is provided with an external pipe 200 detachably connected to it. One end of the coarse filter assembly 21 is fixedly connected to the bottom of the U-shaped bend 20, and the other end is detachably connected to the filter box 22. The fine filter assembly 23 is detachably connected to both the U-shaped bend 20 and the oil inlet 100, and is located between the coarse filter assembly 21 and the oil inlet 100.

[0029] In practical use, during the oil transfer process, when the oil carrying impurities enters through the outer pipe 200, large particles of impurities will slowly settle at the U-shaped bend 20 under gravity and enter the coarse filter assembly 21. Small particles or sand-like impurities that do not settle will enter the fine filter assembly 23 for secondary filtration. The portion entering the coarse filter assembly 21 will settle on the inclined block 214, which gradually presses down on the inner sleeve 211 and spring 213 with the help of the inclined block 214, and moves the inclined block 214 downward to the notch 2100. At this time, large particles of impurities will enter the filter box 22 through the notch, and at the same time, the gravity on the inclined block 214 decreases, and the spring 2100... 13 returns to its initial position, causing the inclined block 214 to return to its original position. Impurities entering the fine filter component 23 are first screened by the lower filter screen 233. Larger particles are blocked and, after a longer sedimentation period, return to the coarse filter component 21. The remaining sandy impurities enter the outer cylinder 230 and are gradually adsorbed by the magnetic balls 234. The upper filter screen 232 is set to filter some sandy impurities that cannot be adsorbed. Therefore, the upper filter screen 232 needs to have stronger filtration performance than the lower filter screen 233. When the fine filter component 23 needs to be replaced after a long period of use, it can be quickly replaced through the connecting component 24.

[0030] When the filtered oil enters the heating chamber 102, it is heated by the heating tube 11 and then flows out of the oil chamber 103 through the fixed tube 120 for later use. During this process, when the temperature of the heating chamber 102 is not up to standard, the memory spring 122 is in a compressed state. At this time, the corresponding notch 1210 and the upper notch 1200 are misaligned, and the flow rate is small. When the temperature rises, the memory spring 122 will extend and drive the bottomless outer tube 121 to move upward, so that the corresponding notch 1210 and the upper notch 1200 overlap, and the flow rate reaches its maximum limit.

[0031] While heating, the amount of reserve oil in the oil chamber 103 is detected based on the position change of the buoyancy plate 130. When the oil level decreases, the buoyancy plate 130 descends, causing the counterweight tube 131 to descend as well. During this process, the counterweight tube 131 first compresses the telescopic spring 133 until it reaches its limit, which then causes the ⊥-shaped rod 132 and its other end displacement plate 123 to move downwards until the displacement plate 123 moves to the lower notch 1201. At this time, the oil in the heating chamber 102 flows into the oil outlet chamber 103. As the amount of oil in the oil outlet chamber 103 gradually increases, the rising process of the buoyancy plate 130 first causes the counterweight tube 131 to rise. During this process, the telescopic spring 133 gradually returns to a pressure-free state and is stretched to its limit as the position of the counterweight tube 131 changes. At this time, the continued rise of the counterweight tube 131 will pull the ⊥-shaped rod 132, causing the displacement plate 123 to move upwards and block the lower notch 1201 again, stopping the refueling of the oil outlet chamber 103.

[0032] Specifically, the coarse filtration assembly 21 includes a filter tube 210, an inner sleeve 211, an outer sleeve 212, a spring 213, and a beveled block 214. The filter tube 210 has no top cover and has a notch 2100 on its side wall. Its upper end penetrates the bottom wall of the U-shaped bend 20 and is fixedly connected to it, while its lower end is detachably connected to the filter box 22. The lower end of the outer sleeve 212 is fixedly connected to the bottom wall of the filter tube 210. The spring 213 is located inside the outer sleeve 212. The lower end of the inner sleeve 211 is fitted inside the outer sleeve 212, and its upper end is fixedly connected to the bottom wall of the beveled block 214. The two ends of the spring 213 are respectively connected to the outer sleeve 212. It is fixedly connected to the inner sleeve 211; the sleeve and spring 213 are set to adapt to the gravity change on the inclined block 214, and under the gravity change, it is displaced to the notch 2100, so that the impurities enter the filter box 22 along the inclined surface of the inclined block 214. Because of the presence of the inclined block 214, if there are too many large particles of impurities in the filter box 22, the filter box 22 can be replaced quickly without stopping the machine, and there will be no large-area oil leakage. After the large particles of impurities settle, even if sandy impurities enter the entire oil circuit, the impact on the oil circuit is smaller than that of large particles of impurities entering the oil circuit, which indirectly increases the service life of the device.

[0033] Specifically, the notch 2100 is located inside the filter box 22, and the inclined surface of the inclined block 214 faces the notch 2100; the orientation of the inclined surface of the inclined block 214 is to facilitate the entry of impurities into the filter box 22 through the notch 2100.

[0034] Specifically, the fine filter assembly 23 includes an outer cylinder 230, two sets of oil seal rings 231, an upper filter screen 232, a lower filter screen 233, and multiple magnetic balls 234. The two ends of the outer cylinder 230 are detachably connected to the U-shaped bend 20 and the oil inlet 100, respectively. The two sets of oil seal rings 231 are located at the two ends of the outer cylinder 230. The upper filter screen 232 and the lower filter screen 233 are detachably connected to the inner walls of the two ends of the outer cylinder 230. The multiple magnetic balls 234 are located between the upper filter screen 232 and the lower filter screen 233. The lower filter screen 233 is used to block large particulate impurities that have not been settled in time, and allows sandy impurities to be adsorbed by the magnetic balls 234 first, and then filtered by the upper filter screen 232 to remove some impurities that cannot be settled or adsorbed, so that they are temporarily stored in the outer cylinder 230.

[0035] Specifically, the connecting assembly 24 includes two sets of connecting rings 240, a screw 241, and two sets of nuts 242. The two sets of connecting rings 240 are respectively fixedly connected to the corresponding positions on the outer side wall of the U-shaped bend 20 and the oil inlet 100. The two ends of the screw 241 pass through the two sets of connecting rings 240 and are threadedly connected to the nuts 242. When the fine filter assembly 23 needs to be replaced after a long period of use, it is only necessary to remove the nuts 242 on one side to increase the distance between the U-shaped bend and the oil inlet 100. After removing the fine filter assembly 23 and replacing it with a new one, it can be tightened again by the nuts 242.

[0036] Specifically, the oil quantity control component 12 includes a fixed tube 120, a bottomless outer tube 121, a memory spring 122, and a displacement plate 123. The fixed tube 120 passes through and is fixedly connected to the partition 104, and the fixed tube 120 has an upper notch 1200 and a lower notch 1201. The bottomless outer tube 121 is sleeved on the outer side of the upper end of the fixed tube 120, and its side wall has a corresponding notch 1210 corresponding to the position of the upper notch 1200. The memory spring 122 is located between the bottomless outer tube 121 and the fixed tube 120, and it is fixed to both the fixed tube 120 and the bottomless outer tube 121. The displacement plate 123 is located inside the fixed tube 120 and is slidably connected to the fixed tube 120. By utilizing the memory spring 122's short length at low temperatures and long length at high temperatures, its length changes with temperature, thereby driving the position of the bottomless outer tube 121. The flow rate is controlled by the staggering of the upper notch 1200 and the corresponding notch 1210, preventing unheated oil from entering the oil outlet chamber 103 too quickly. It is worth noting that when the memory spring 122 is at its shortest, the upper notch 1200 and the corresponding notch 1201 cannot be completely staggered. This setting is to avoid the situation where there is no oil in the oil outlet chamber 103.

[0037] Specifically, the memory spring 122 has a memory temperature of 55-65℃. In the hard phase, the corresponding notch 1210 and the upper notch 1200 overlap. Oil at 60℃ is most effective at removing impurities, and the memory spring 122 is set to achieve the optimal oil temperature.

[0038] Specifically, the counterweight assembly 13 includes a buoyancy plate 130, a counterweight tube 131, a U-shaped rod 132, and a telescopic spring 133. The lower end of the counterweight tube 131 is fixedly connected to the buoyancy plate 130. The telescopic spring 133 is located inside the counterweight tube 131. The U-shaped rod 132 is located inside the counterweight tube 131, passing through the telescopic spring 133 and penetrating the top wall of the counterweight tube 131 and the bottom wall of the fixed tube 120, and is fixedly connected to the displacement plate 123. The two ends of the telescopic spring 133 are respectively fixedly connected to the top wall of the counterweight tube 131 and the U-shaped rod 132. The buoyancy plate 130 is used to monitor the liquid level in the oil outlet chamber 103. The change in the position of the buoyancy plate 130 does not immediately change the position of the displacement plate 123, but instead first stretches and compresses the telescopic spring 133 to locate the lowest and highest liquid levels.

[0039] Specifically, a temperature conduction block 1211 is provided on the top wall of the bottomless outer tube 121, and the temperature conduction block 1211 is in contact with the memory spring 122; in order to make better use of the memory spring 122, a temperature conduction block 1211 is added for temperature conduction.

[0040] Specifically, the top wall of the housing 10 is provided with a filling port 105; considering the possible oil loss during the filtration process, the filling port 105 can be used to add oil when the oil level is insufficient.

[0041] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
