The aviation kerosene pipeline filter device is a key equipment to ensure the purity and quality of aviation kerosene. It plays an important role in all aspects of aviation kerosene from refining to filling. The aviation kerosene pipeline filter device is mainly used to remove impurities and moisture in aviation kerosene to prevent these pollutants from damaging aircraft engines, thereby ensuring flight safety.

[0003] When traditional kerosene filtering devices filter aviation kerosene, due to long-term filtration, the filter element becomes blocked and cannot be discharged normally. The filter element needs to be replaced after the equipment is opened. There are problems such as low filtration efficiency, easy clogging of the filter element and difficulty in cleaning and maintenance. These problems not only increase maintenance costs, but also may pose a potential threat to aviation safety. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that a filter element cannot be cleared in time after being blocked when filtering kerosene for a long time, and proposes an aviation kerosene pipeline filtering device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A filtration device for aviation kerosene pipelines comprises a filter with a feed inlet and a discharge port and a filter element installed inside the filter, wherein at least two filter elements are provided, and further comprises: a sleeve ring sleeved on the outer wall of the filter element, wherein a swinging part for driving the sleeve ring to swing back and forth is provided inside the filter.

[0007] Preferably, the swinging part comprises a corrugated slide rail fixedly connected to the inside of the filter, the collar on one side is arranged in close contact with the corrugated slide rail, and a lifting part for driving the collar to rise along the corrugated slide rail is provided in the filter.

[0008] In order to ensure synchronous sliding of the rings on both sides, preferably, one of the rings is fixedly connected with a ball, the ball is slidably installed inside the corrugated slide rail, one of the rings is fixedly connected with a slider, a slide groove is opened inside the filter, and the slider is slidably installed inside the slide groove.

[0009] In order to drive the ring to move, the lifting part further includes a connecting plate, the connecting plate is fixedly connected between two adjacent rings, a support rod is fixedly connected to the connecting plate, and both ends of the support rod are fixedly connected to floats.

[0010] In order to facilitate feeding and discharging, further, a bottom plate is fixedly installed in the filter, a partition is fixedly connected to the bottom plate, the free end of the partition is fixedly connected to the filter, and the partition separates the bottom plate and the filter into two cavities, one side cavity cooperates with the feed port, and the other side cavity cooperates with the discharge port, and the two cavities are connected to the filter element.

[0011] In order to preliminarily filter the kerosene, further, connecting holes are opened on both sides of the bottom plate, a filter screen is fixedly installed in the connecting hole close to the feed port, and the discharge port is fixedly connected to the filter element through the connecting hole on the other side.

[0012] In order to cooperate with the vibration of the swinging part, further, the bottom plate and the inside of the filter are fixedly connected to a limiting plate, both sides of the limiting plate are connected to a supporting plate, the filter element is sleeved on the supporting plate, and a supporting spring is fixedly installed between the inner wall of the support plate and the outer wall of the limiting plate.

[0013] Compared with the prior art, the utility model provides an aviation kerosene pipeline filtering device, which has the following beneficial effects:

[0014] 1. The aviation kerosene pipeline filter device, through the setting of the swing part, when kerosene flows through the filter, the float rises with the rise of the kerosene liquid level, and drives the connecting plate and the rings on both sides to slide along the corrugated slide rail and the slide groove through the support rod, forming a reciprocating swinging motion trajectory. This motion process not only promotes the flow of kerosene, but also drives the slight vibration of the filter element, so that impurities and particulate matter attached to the surface of the filter element can fall off, thereby maintaining the patency of the filter element, improving the filtering efficiency, realizing automatic cleaning and dredging of the filter element, and effectively solving the problem that the filter element in the traditional kerosene filtering device is easy to be blocked and difficult to clean and maintain.

[0015] 2. The aviation kerosene pipeline filter device uses a partition design to reasonably separate the internal space of the filter, so that the feeding and discharging processes do not interfere with each other. At the same time, the filter screen near the feeding port is used as a preliminary filtering layer to intercept larger particles of impurities, reduce the burden of the filter element, and extend its service life. The discharge port is directly connected to the filter element through a connecting hole, ensuring that the filtered kerosene can be discharged smoothly.

[0016] 3. The aviation kerosene pipeline filter device provides additional support and buffering for the filter element through the combined use of a limit plate and a support spring. When the filter element is impacted by the flow of kerosene or vibrated by the swinging part, the support spring can absorb part of the impact force to prevent the filter element from being damaged due to excessive vibration. The elasticity of the spring can also be used to apply a reaction force to the filter element to increase the vibration frequency. At the same time, it also ensures the stable position of the filter element in the filter, avoiding the situation where the filtering effect is affected by position offset.

[0017] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. When the filter element is blocked during kerosene filtering, the rising kerosene level drives the swing part to drive the filter element to swing, thereby achieving the effect of automatic unblocking.

When the kerosene level rises, the float 3 floats up accordingly, and drives the collar 33 to swing through the support rod 31 and the connecting plate 32, thereby achieving the effect of vibration dredging of the clogged filter element 2 and preventing the equipment from being blocked during the filtering process.

[0028] Reference Figure 2-Figure 3A bottom plate 15 is fixedly installed in the filter 1, which provides support and separation functions. A partition 13 is fixedly connected to the bottom plate 15, and the free end of the partition 13 is fixedly connected to the filter 1. The partition 13 separates the bottom plate 15 and the filter 1 into two cavities. One side cavity cooperates with the feed port 11, and the other side cavity cooperates with the discharge port 12. This separation allows the kerosene to go through a preliminary guiding stage before entering the filter element 2. One side cavity cooperates with the feed port 11 as the entrance area of ​​kerosene. Kerosene enters this cavity through the feed port 11 and is ready to be filtered. The other side cavity Cooperating with the discharge port 12, as the outlet area of ​​the filtered kerosene, the kerosene filtered by the filter element 2 will flow out from this cavity through the discharge port 12. Connecting holes are opened on both sides of the bottom plate 15. A filter screen 14 is fixedly installed in the connecting hole close to the feed port 11. The filter screen 14 serves as a preliminary filtering device, which can block larger impurities and particulate matter in the kerosene and prevent them from directly entering the filter element 2, thereby extending the service life of the filter element 2 and improving the filtering efficiency. The discharge port 12 is fixedly connected to the filter element 2 through the connecting hole on the other side, so that the kerosene filtered by the two filter elements 2 can be directly output through the discharge port 12.

[0029] Reference Figure 2 , Figure 3 , Figure 5 The bottom plate 15 and the inside of the filter 1 are fixedly connected with a limit plate 4, and support plates 42 are connected on both sides of the limit plate 4. The filter element 2 is sleeved on the support plate 42, and the support plates 42 are connected on both sides of the limit plate 4, providing additional support for the filter element 2. A support spring 41 is fixedly connected to the support plate 42, and the free end of the support spring 41 is fixedly connected to the limit plate 4. The support spring 41 can also allow the filter element 2 to have a certain movement space when the ring 33 rises and drives the filter element 2 to swing, which helps to prevent the filter element 2 from being deformed or damaged due to excessive pressure. At the same time, the elasticity of the support spring 41 provides a reverse force for the filter element 2, so that the filter element 2 vibrates at a higher frequency, and the blocked filter element 2 is more effectively dredged.

[0030] The working principle of this utility model:

[0031] When aviation kerosene enters the filter 1 through the feed port 11, it will first pass through the filter screen 14 on the bottom plate 15 close to the feed port 11. The filter screen 14 will initially block large particles of impurities in the kerosene to ensure that only relatively clean kerosene enters the filter element 2 area. Then, the kerosene will flow through two separated filter elements 2, filtering the coalescing filter element 2 and the separating filter element 2. The former is responsible for removing tiny particles and impurities in the kerosene, and the latter is responsible for further separating water or other immiscible liquids in the kerosene to ensure the purity of the kerosene.

[0032] During the filtering process, if the filter element 2 is clogged, kerosene will accumulate inside the filter 1, and the change in the kerosene level will trigger the floating ball 3 to float up and down. As the kerosene level rises, the floating ball 3 rises accordingly, and through the transmission effect of the support rod 31 and the connecting plate 32, the ring 33 mounted on the outer wall of the filter element 2 is driven to swing back and forth. This swinging movement of the ring 33 realizes the automatic vibration dredging of the filter element 2 through the linkage mechanism of the connecting plate 32, the support rod 31 and the floating ball 3, and effectively prevents the problem of the filter element 2 being blocked due to long-term work.

[0033] In addition, the swing of the ring 33 is also supported by the corrugated slide 17 and the slide groove 16. The ball 34 slides smoothly in the corrugated slide 17, and the corrugated slide 17 is set high and low, so that the ball 34 drives the ring 33 to vibrate. The stable movement of the slider 35 in the slide groove 16 makes the rings 33 on both sides vibrate synchronously, and ensures the stability and reliability of the two rings 33 during the swinging process. This design not only improves the working efficiency of the filtering device, but also extends the service life of the filter element 2.

[0034] At the same time, the limit plate 4 and the support plate 42 and support spring 41 thereon also play an important role. The limit plate 4 limits the position of the filter element 2 to prevent it from unnecessary movement during operation; and the support plate 42 and support spring 41 provide additional support and buffering for the filter element 2, so that the filter element 2 can remain stable when vibrated by the ring 33, and the elastic force of the support spring 41 further enhances the vibration effect, thereby more effectively clearing the clogged filter element 2.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
