Description

Technical Field

[0001] This utility model relates to the field of automotive engine technology, and in particular to an oil filtration assembly for a turbocharger lubrication device. Background Technology

[0002] During the operation of a turbocharger, the lubrication system plays a crucial role. It continuously delivers lubricating oil to provide lubrication and cooling for the high-speed rotating components inside the turbocharger, ensuring the stable operation and service life of the equipment. As the core component of the lubrication system, the oil filter assembly must effectively filter impurities in the lubricating oil to prevent impurities from entering the gaps between moving parts and causing wear, jamming, and other malfunctions. Therefore, the filtration effect and reliability of the filter assembly directly affect the overall working performance of the turbocharger.

[0003] The existing technology has the following drawbacks: impurities in the lubricating oil continuously adhere to the filter screen mesh, which easily causes filter screen blockage as the usage time increases, leading to a decrease in lubricating oil flow efficiency and thus affecting the lubrication effect. Traditional filter screen unclogging methods mostly rely on manual operation, requiring the machine to be stopped and the filter assembly to be disassembled to clean the filter screen impurities. This is not only cumbersome and labor-intensive, but also occupies a lot of equipment downtime, seriously reducing the operating efficiency of the turbocharger. Especially for continuously operating industrial equipment, the downtime losses caused by manual filter screen unclogging are even more significant. Therefore, an oil filtration assembly for a turbocharger lubrication device is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an oil filtration assembly for a turbocharger lubrication device, aiming to solve the problem of cumbersome filter cleaning steps in the prior art.

[0006] The movable mechanism includes a trapezoidal block that is slidably connected to the inner wall of the housing. The left sidewall of the trapezoidal block is elastically connected to the housing via a movable spring.

[0007] As a further description of the above technical solution:

[0008] The sealing assembly includes a rubber block inserted into the inner wall of a long rod, and the inner wall of the rubber block is threaded with bolts.

[0013] As a further description of the above technical solution:

[0014] The top of the unblocking plate is provided with a round rod, which is inserted into the inner wall of the filter screen.

[0015] As a further description of the above technical solution:

[0016] The left sidewall of the trapezoidal block is fixedly connected to one end of the movable spring, and the other end of the movable spring is fixedly connected to the left inner wall of the housing.

[0017] As a further description of the above technical solution:

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by means of an electrically controlled telescopic rod driven linkage structure, impurities in the filter screen can be accurately pushed out through the round rod of the unblocking plate, thereby achieving automatic unblocking of the filter screen. After unblocking, each component can automatically return to its original position under the action of spring force and its own gravity, without the need for additional manual operation, thus improving the convenience and efficiency of unblocking the filter screen.

[0023] 2. In this utility model, in the initial state, the rubber block is deformed by the gravity of the unblocking plate combined with the pulling force of the long rod, which can tightly seal the sliding groove of the long rod, effectively preventing lubricating oil from seeping in. Moreover, when replacing the rubber block, only the bolts need to be unscrewed manually, making the disassembly and assembly steps simple and reducing the difficulty of maintenance.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figures 1-3This utility model provides an embodiment of an oil filtration assembly for a turbocharger lubrication device, comprising a housing 1, an oil inlet pipe 13 fixedly connected to the outer wall of the housing 1 (the oil inlet pipe 13 being the lubricating oil outlet), an electric telescopic rod 2 provided on the inner wall of the housing 1 (the electric telescopic rod 2 being a mechanical device that achieves linear reciprocating motion via electric drive), a disc 3 fixedly connected to the movable end of the electric telescopic rod 2, a pressing rod 4 fixedly connected to the outer wall of the disc 3, a long rod 7 slidably connected to the inner wall of the housing 1, and a slot corresponding to the long rod 7 provided on the housing 1, allowing the long rod 7 to move left and right, and a filter screen 10 fixedly connected to the inner wall of the housing 1 (the filter screen 10 filtering impurities in the lubricating oil). The inner wall of the housing 1 is slidably connected to a drain plate 11, which has multiple sets of round holes to ensure that the lubricating oil flows out. The bottom end of the drain plate 11 is fixedly connected to a bevel block 12, which has bevels on its lower left and lower right sides. The bottom end of the housing 1 is fixedly connected to an oil outlet pipe 14, which is connected to the oil inlet on the turbocharger. The inner wall of the housing 1 is provided with a movable mechanism, and the inner wall of the long rod 7 is provided with a sealing assembly. The movable mechanism includes a trapezoidal block 5, and the housing 1 has a slot corresponding to the trapezoidal block 5, which allows the trapezoidal block 5 to move left and right. The trapezoidal block 5 is slidably connected to the inner wall of the housing 1, and the left side wall of the trapezoidal block 5 is elastically connected to the housing 1 through a movable spring 6.

[0033] Reference Figures 2-4 The sealing assembly includes a rubber block 8, which is inserted into the inner wall of a long rod 7. The rubber block 8 has a protrusion, and the long rod 7 has a slot corresponding to the protrusion. The inner wall of the rubber block 8 is threaded with a bolt 9, and the rubber block 8 has a thread that matches the bolt 9. The top of the rubber block 8 contacts the lower surface of the inclined block 12. When the rubber block 8 presses the inclined block 12, it causes the inclined block 12 to move upward. The bolt 9 is threaded into the inner wall of the long rod 7, and the long rod 7 has a thread that matches the bolt 9.

[0034] Reference Figure 2 , Figure 3 and Figure 5 The extrusion rod 4 is slidably connected to the inner wall of the housing 1. The housing 1 has a slot corresponding to the extrusion rod 4, allowing the extrusion rod 4 to move vertically. The upper right side of the trapezoidal block 5 is provided with an inclined surface. The bottom end of the extrusion rod 4 contacts the inclined surface. When the extrusion rod 4 extrudes the trapezoidal block 5, it causes the two sets of trapezoidal blocks 5 to move closer to each other. The top of the unblocking plate 11 is provided with a round rod, which is inserted into the inner wall of the filter screen 10. The round rod will push out the impurities blocking the mesh of the filter screen 10. The size of the round rod is consistent with the aperture of the filter screen 10. The left side wall of the trapezoidal block 5 is fixedly connected to one end of the movable spring 6. The other end of the movable spring 6 is fixedly connected to the left inner wall of the housing 1. When the two sets of trapezoidal blocks 5 move closer to each other, the movable spring 6 is compressed. When resetting, the elastic force of the movable spring 6 is used to separate the two sets of trapezoidal blocks 5.

[0035] Working principle: When it is necessary to unclog the filter screen 10, the electrically controlled telescopic rod 2 moves the disc 3 and the squeezing rod 4 downwards. The squeezing rod 4 squeezes the two sets of trapezoidal blocks 5 together, and the trapezoidal blocks 5 squeeze the movable spring 6. At the same time, the trapezoidal blocks 5 move the long rod 7 and the rubber block 8 together, and the rubber block 8 squeezes the inclined surface of the inclined block 12, causing the inclined block 12 to move the unclogging plate 11 upwards. When the round rod on the unclogging plate 11 is inserted into the mesh of the filter screen 10, the round rod will push out the impurities in the filter screen 10. When the unclogging is completed, the electrically controlled telescopic rod 2 moves the disc 3 and the squeezing rod 4 back to the initial position. As the squeezing rod 4 no longer contacts the trapezoidal block 5, it moves the long rod 7 and the rubber block 8 back to the initial position under the elastic force of the movable spring 6. At the same time, the unclogging plate 11 moves downwards to the initial position under its own gravity.

[0036] When the drain cleaning plate 11 is in its initial position, the drain cleaning plate 11 will press the rubber block 8 against the inner wall of the housing 1 under its own weight. At the same time, with the pulling force of the long rod 7 on the rubber block 8, the rubber block 8 will deform and block the groove of the long rod 7 to prevent lubricating oil from entering. When the rubber block 8 needs to be replaced, simply unscrew the bolt 9 manually to remove the rubber block 8. During installation, manually align the rubber block 8 with the direction of insertion into the long rod 7 and manually tighten the bolt 9.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
