Description

Technical Field

[0001] This utility model relates to the field of aviation fuel filtration equipment maintenance technology, and in particular to an auxiliary tool for disassembling the filter element of an oil filter separator. Background Technology

[0002] Aviation fuel filters are primarily used to filter impurities and moisture from aviation fuel during the fuel receiving and dispensing processes, and are crucial equipment for ensuring the quality of aviation fuel. With the rapid development of the aviation industry, the supply of aviation fuel from airport fuel depots has increased dramatically, leading to a corresponding increase in the number of fuel pumps and the corresponding fuel filter separators downstream of these pumps. According to industry standards, fuel filter separators require regular inspection and cleaning to ensure their proper functioning.

[0003] Current oil filter separators typically employ a double-layer design. During maintenance, workers must sequentially remove the upper and lower filter elements for inspection and cleaning. However, due to the large size of oil filter separators (internal wall height exceeding 2m), and the use of caps, rubber gaskets, retaining rings, and bolts to secure the upper filter element during installation, numerous problems arise during disassembly and assembly. For instance, components are prone to falling after removal. Since these components are usually made of stainless steel or rubber, they are difficult to attract directly with a magnet, and oil vapor often adheres to their surfaces. This allows components to easily fall into the oil filter separator, potentially clogging the internal components and affecting normal operation. Furthermore, workers are required to clean up the fallen components, increasing maintenance difficulty and risk, and reducing maintenance efficiency.

[0004] Therefore, there is an urgent need to design an auxiliary tool for disassembling oil filter separator elements to facilitate the disassembly and assembly of filter elements inside the oil filter separator, especially suitable for the disassembly and assembly of upper filter elements. Utility Model Content

[0005] The purpose of this utility model is to overcome the defects of the existing technology and provide an auxiliary tool for disassembling oil filter elements that can facilitate workers to quickly remove the filter element, prevent the disassembled parts from falling and clogging the oil filter separator, reduce maintenance difficulty and risk, and improve maintenance efficiency.

[0006] To achieve the above objectives, this utility model provides an auxiliary tool for disassembling an oil filter separator element, including a sleeve, a baffle, a handle, and a clamping assembly. The baffle is detachably installed inside the sleeve and has a through hole for accessories to pass through. The baffle is used to abut against the top surface of the filter element cap. The handle is movably installed above the baffle, and the clamping assembly is located below the baffle. The clamping assembly includes several clamping plates, which are spaced apart along the circumference of the sleeve. All clamping plates are movably and limitably installed on the sleeve to clamp the filter element.

[0007] Preferably, the sleeve includes a retaining portion and an insertion portion for the filter element to extend into, a plurality of clamps are located on the insertion portion, and an annular flange for mounting the baffle is formed between the retaining portion and the insertion portion.

[0008] Preferably, the baffle is made of a flexible material, and the outer wall of the baffle is provided with a groove along its circumference for the annular flange to extend into.

[0009] Preferably, the outer wall of the insertion part is provided with a plurality of locking holes evenly and at intervals along its circumference, and the clamping assembly further includes a plurality of locking pins, each of which is detachably installed in a plurality of locking holes, and each of the locking pins is provided with a clamping plate at one end extending into the sleeve.

[0010] Preferably, the other end of one or more of the locking pins extends out of the sleeve and is detachably fitted with a throttle.

[0011] Preferably, a flexible pad is provided on the side of any of the clamps away from the inner wall of the sleeve, and anti-slip texture is formed on the side wall of the flexible pad.

[0012] Preferably, the handle is fitted with a flexible sleeve.

[0013] Beneficial effects:

[0014] 1. In the auxiliary tool for disassembling the filter element of an oil filter separator according to this utility model, the sleeve is axially limited by the baffle to facilitate the subsequent clamping assembly to clamp and fix the filter element. The baffle can also block the gap between the filter element cap and the oil filter separator, thereby preventing the disassembled parts from falling into the oil filter separator and causing blockage, ensuring the normal operation of the subsequent equipment. No additional cleaning of fallen parts is required by the staff, which significantly reduces the difficulty and risk of maintenance and makes it reliable in use.

[0015] 2. In the auxiliary tool for disassembling the filter element of the oil filter separator of this utility model, the filter element can be clamped and limited at multiple points by several clamping plates, so that the workers can directly take out the filter element by pulling the handle without wearing oil-resistant gloves or other gripping tools. This not only simplifies the disassembly steps of the filter element and improves the disassembly efficiency, but also effectively avoids the filter element from being damaged due to slipping and bumping.

[0016] 3. In the auxiliary tool for disassembling the filter element of the oil filter separator of this utility model, since the baffle is detachably installed in the sleeve, the operator can meet the disassembly needs of filter elements of various sizes by replacing baffles of different specifications. It has high versatility and flexibility of use, and the structural design is simple and reasonable. Attached Figure Description

[0030] Example 1:

[0031] This utility model proposes an auxiliary tool for disassembling the filter element of an oil filter separator.

[0032] In one embodiment of this utility model, an auxiliary tool for disassembling an oil filter separator element includes a sleeve 1, a baffle 2, a handle 3, and a clamping assembly 4. The baffle 2 is detachably installed inside the sleeve 1, and a through hole is provided on the baffle 2 for the accessory to pass through. The baffle 2 is used to abut against the top surface of the filter element cap 15. The handle 3 is movably installed above the baffle 2, and the clamping assembly 4 is located below the baffle 2. The clamping assembly 4 includes a plurality of clamping plates 5, which are spaced apart along the circumference of the sleeve 1. The clamping plates 5 are all movably installed on the sleeve 1 in a limited manner to clamp the filter element.

[0033] Working principle: In the process of using this utility model, an auxiliary tool for disassembling an oil filter separator element, the operator puts the sleeve 1 on the filter element, so that the bottom surface of the inner baffle 2 of the sleeve 1 abuts against the top surface of the filter element cover 15. The baffle 2 covers the gap between the filter element cover 15 and the oil filter separator, thereby effectively preventing the parts from falling into the oil filter separator after disassembly. At the same time, the filter element can be clamped and fixed by several clamps 5 in the clamping assembly 4. The operator can quickly remove the filter element by pulling the handle 3. The operation is simple and convenient.

[0034] Specifically, such as Figures 1 to 5 As shown, in the auxiliary tool for disassembling the filter element of an oil filter separator according to this utility model, since the sleeve 1 is detachably equipped with a baffle 2, and the baffle 2 has a through hole for accessories to pass through, the accessories include but are not limited to bolts, retaining rings, gaskets, and caps for fixing the filter element, after the operator puts the sleeve 1 on the filter element, the bottom surface of the baffle 2 can abut against the top surface of the filter element cap 15. This not only allows the baffle 2 to axially limit the sleeve 1 so that the subsequent clamping assembly 4 can clamp and fix the filter element, but also allows the baffle 2 to block the gap between the filter element cap 15 and the oil filter separator, thereby preventing the disassembled accessories from falling into the oil filter separator and causing blockage, ensuring the normal operation of the subsequent equipment, eliminating the need for operators to clean up the fallen accessories, significantly reducing maintenance difficulty and risk, and ensuring reliable use.

[0035] Furthermore, after the staff places the baffle 2 on the filter element cover 15, the staff can disassemble the relevant fixing accessories. At the same time, after the accessories are disassembled, the filter element cover 15 releases its abutment limit on the filter element, and the staff can clamp and fix the filter element through the clamping assembly 4 located below the baffle 2 for easy removal. Specifically, since several clamping plates 5 in the clamping assembly 4 are all movably and limitably installed on the sleeve 1, the clamping plates 5 can be movably and limitably installed on the sleeve 1 by means of bolt connection, etc., so that the staff can turn the bolts to drive the clamping plates 5 to move radially along the sleeve 1 and abut against the outer wall of the filter element, thereby realizing multi-point clamping and limiting of the filter element, so that the staff can directly remove the filter element by pulling the handle 3 without wearing oil-resistant gloves to grasp the filter element. This not only simplifies the filter element removal steps and improves the removal efficiency, but also effectively avoids the filter element being damaged due to slippage and impact.

[0036] It should be noted that, since the baffle 2 is detachably installed inside the sleeve 1, the detachable installation method between the baffle 2 and the sleeve 1 can be a threaded connection. This allows operators to meet the disassembly needs of filter elements of various sizes by replacing baffles 2 of different specifications, resulting in high versatility and flexibility of use, and a simple and reasonable structural design. Furthermore, in this utility model's auxiliary tool for disassembling oil filter separator elements, the baffle 2 is preferably a die-cast annular baffle 2, which can be adapted to the filter element cap 15 to ensure a shielding effect.

[0037] In one embodiment, the sleeve 1 includes a retaining portion 6 and an insertion portion 7 for the filter element to extend into, a plurality of clamping plates 5 are located on the insertion portion 7, and an annular flange 8 for mounting a baffle 2 is formed between the retaining portion 6 and the insertion portion 7. Specifically, as Figures 1 to 4 As shown, the enclosure 6 forms an external protective frame, effectively preventing disassembled parts from accidentally falling off the baffle 2 and avoiding loss, while further improving the anti-falling effect. Understandably, in use, the auxiliary tool for disassembling an oil filter separator element of this utility model allows the operator to directly insert the filter element into the insertion part 7 and allow related parts to pass through the through holes on the baffle 2. This enables the sleeve 1 to be installed and positioned, facilitating the subsequent clamping assembly 4 to clamp and limit the filter element. The structural design is simple and reasonable. Furthermore, since an annular flange 8 is formed between the enclosure 6 and the insertion part 7, the operator can detachably install the baffle 2 onto the annular flange 8 using bolt connections or other methods, facilitating the disassembly or replacement of the baffle 2. The operation is simple and convenient.

[0038] In one embodiment, the baffle 2 is made of a flexible material, and a groove 9 for the annular flange 8 to extend into is provided on the outer wall of the baffle 2 along its circumference. Figure 1 and Figure 4As shown, it can be understood that when the staff needs to disassemble or replace the baffle 2, since the baffle 2 is made of a flexible material, specifically a rubber material, the baffle 2 can undergo elastic deformation and return to its original shape when there is no external force. That is, the staff can directly pull the baffle 2 out from the sleeve 1, so that the annular flange 8 and the slot 9 are disengaged and locked, without the need to disassemble bolts or other fasteners. This simplifies the disassembly and assembly steps of the baffle 2, improves the efficiency of disassembly, assembly and replacement of the baffle 2, and is reliable in use.

[0039] In one embodiment, a plurality of locking holes are evenly and spaced along the circumference of the outer wall of the insertion part 7. The clamping assembly 4 also includes a plurality of locking pins 10, which are detachably installed in the plurality of locking holes one by one. Each of the locking pins 10 has a clamping plate 5 at one end that extends into the sleeve 1. Figures 1 to 4 As shown, it can be understood that the locking post 10 can be a stud or the like in the prior art, and the locking hole can be a threaded hole. Through the threaded engagement of the locking post 10 and the locking hole, the clamping plate 5 can not only be stably installed on the insertion part 7, but also facilitate the operator to screw the locking post 10 to adjust the radial installation position of the clamping plate 5 and clamp and limit the filter element. The structural design is simple and reasonable.

[0040] In one embodiment, the other end of a plurality of locking pins 10 extends outside the sleeve 1 and is detachably fitted with a handle 11. Specifically, as shown... Figures 1 to 4 As shown, the throttle 11 allows workers to turn the locking pin 10 without the need for external tools (such as wrenches), facilitating the adjustment of the clamping plate 5 and improving the efficiency of filter element disassembly.

[0041] In one embodiment, a flexible pad 12 is provided on the side of any clamping plate 5 away from the inner wall of the sleeve 1, and anti-slip texture 13 is formed on the sidewall of the flexible pad 12. Specifically, as shown in the figure... Figures 1 to 4 As shown, the flexible pad 12 can be made of rubber material as in the prior art. The flexible pad 12 ensures the uniform distribution of clamping force and prevents damage and slippage on the filter element surface. Furthermore, because anti-slip textures 13 are formed on the sidewall of the flexible pad 12, these textures can break through the oil film on the filter element surface, thereby significantly increasing the friction between the flexible pad 12 and the outer wall of the filter element. This effectively reduces the risk of the filter element sliding relative to the clamping plate 5 during the lifting process, ensuring reliable use.

[0042] In one embodiment, such as Figures 1 to 4As shown, a flexible sleeve 14 is fitted onto the handle 3. Understandably, workers can lift the sleeve 1 and the filter element by gripping the flexible sleeve 14 on the handle 3, thereby improving the comfort of the worker's hands. In addition, anti-slip protrusions can be provided on the flexible sleeve 14 to increase the friction between the worker's hand and the flexible sleeve 14, preventing the filter element from slipping and falling and being damaged during the lifting process.

[0043] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
