Description

Technical Field

[0001] The utility model relates to the technical field of filter element disassembly and assembly, and more specifically, to a convenient filter element disassembly and assembly tool. Background Technique

[0002] A filter element is arranged in a produced water coalescing filter of an ethylene glycol regeneration device on an offshore production and storage oil platform for filtering products. During the replacement and cleaning operations, since the filter element has a cylindrical structure and a plurality of keyways are evenly distributed on its top, when cleaning the filter element or replacing the filter element, it is necessary to separate the filter element from the connecting base, and the filter element is long enough and heavy, and the distance between the filter element and the end cover is far. Therefore, the disassembly and assembly of the filter element are extremely inconvenient, and it is extremely difficult for manual disassembly and assembly. Also, because there is a small amount of volatile liquid inside the coalescing filter, close contact poses a potential health hazard to the human body. Therefore, a special disassembly and assembly tool is needed to improve the disassembly and assembly efficiency and save working hours.

[0003] There is a prior Chinese utility model with a publication number of CN213352300U, which discloses a filter element disassembly device for disassembling the filter element in a security filter, including a central vertical rod and a cross rod. A threaded hole is arranged on the cross rod, the central vertical rod vertically penetrates through the threaded hole, an external thread is arranged on the central vertical rod and matches the threaded hole, both ends of the cross rod are arranged on the shell of the security filter, one end of the central vertical rod is connected to the filter element, and by rotating the other end of the central vertical rod to drive the filter element to move vertically. Since the central vertical rod is connected to the filter element, by rotating the other end of the central vertical rod to drive the filter element to move vertically, the workload in the filter element replacement process can be reduced, manpower and material resources can be saved. On the other hand, it can also ensure that the security filter is not damaged during the filter element replacement process and improve the service life of the security filter. In addition, the filter element disassembly device provided by this utility model has a simple structure and is convenient to operate.

[0004] However, in the above technical solution, the vertical rod is threadedly connected to the cross rod, and the movement of the vertical rod in the vertical direction is restricted by the thread, resulting in a low disassembly efficiency. And the cross rod needs to be fixed on the shell of the filter, and during the operation, the user needs to be close to the filter. When there are harmful substances in the working environment of the filter element, it is possible that the user will be harmed when approaching the filter. Summary of the Utility Model

[0005] In order to solve the above problems, the utility model provides a convenient filter element disassembly and assembly tool. By setting an extension rod and a hook-shaped structure, the keyways on the upper surface of the filter element are hooked by the hook-shaped structure, and the filter element is disassembled by rotating the handle. After the disassembly is completed, the filter element can be taken out directly by pulling. The disassembly efficiency is high. At the same time, the extension rod enables the user to perform the disassembly and assembly operations of the filter element at a certain distance from the filter element, avoiding the possibility of harm to the user caused by harmful substances at the filter element installation location.

[0006] To solve the above technical problems, the technical solution adopted by the present utility model is as follows: A convenient disassembly and assembly tool for a filter element, comprising a handle, an extension rod and a hook head. The handle is fixed to one end of the extension rod, the other end of the extension rod is fixed to the hook head, and a plurality of hook-shaped structures are arranged along the circumferential direction at the end of the hook head away from the extension rod.

[0007] In this technical solution, a plurality of hook-shaped structures are arranged on the hook head. The hook-shaped structures can hook the clamping keys on the filter element. When the filter element needs to be disassembled, the hook head is rotated, and the hook-shaped structures on the hook head hook the clamping keys on the filter element, driving the filter element to rotate so as to realize the disassembly of the filter element. A plurality of hook-shaped structures are provided and evenly arranged along the circumferential direction, so that the hook head can hook a plurality of clamping keys at the same time, and ensure that the filter element can be evenly stressed during rotation, avoiding eccentricity during rotation due to uneven stress on the filter element, which affects the normal disassembly of the filter element. There is a small amount of volatile liquid in the environment where the filter element is installed inside the coalescing filter. Close contact poses a risk of injury to the human body. Therefore, it is necessary for the user to operate the rotation of the hook head at a certain distance to disassemble the filter element. At the same time, the plurality of hook-shaped structures on the hook head provide a plurality of fixing points between the hook head and the filter element. After each hook-shaped structure hooks the clamping key on the filter element, the relative position between the filter element and the hook head is completely fixed. The tool can drive the movement of the filter element by driving the movement of the hook head, realizing the handling of the filter element. The hook head is connected with an extension rod, and the user can operate the rotation of the hook head through the extension rod, so that the user can disassemble the filter element at a certain distance from the disassembly position of the filter element, avoiding the situation that the harmful substances in the filter element installation environment cause damage to the staff. A handle is also fixed to the end of the extension rod away from the hook head. The handle is in a rod-shaped structure, and the extension rod is fixed at the midpoint of the handle. When the user uses it, both hands hold the two ends of the handle respectively, forming a labor-saving lever with the extension rod located at the midpoint of the handle, so that the user can more easily loosen the filter element to achieve disassembly. When the filter element is completely loosened, the user can directly pull out the filter element by pulling. The disassembly efficiency is high, and the user does not need to approach the working environment of the filter element during the disassembly and transportation of the filter element, which is suitable for the user to load and unload the filter element in a dangerous working environment.

[0008] Preferably, the hook head is a cylindrical tubular structure, one end of the hook head is fixedly connected to the extension rod, and the hook-shaped structure is provided on the tube wall at the other end of the hook head.

[0024] Embodiment 1

[0025] As Figure 1As shown in the figure, a convenient disassembly and assembly tool for a filter element includes a handle 1, an extension rod 2 and a hook head 3. The handle 1 is fixed to one end of the extension rod 2, and the other end of the extension rod 2 is fixed to the hook head 3. A plurality of hook-shaped structures 31 are arranged along the circumferential direction at the end of the hook head 3 away from the extension rod 2. A plurality of hook-shaped structures 31 are arranged on the hook head 3. The hook-shaped structures 31 can hook the clamping keys on the filter element. When the filter element needs to be disassembled, the hook head 3 is rotated. The hook-shaped structures 31 on the hook head 3 hook the clamping keys on the filter element, driving the filter element to rotate so as to realize the disassembly of the filter element. A plurality of hook-shaped structures 31 are provided and are evenly arranged along the circumferential direction, so that the hook head 3 can hook a plurality of clamping keys, and it is ensured that when rotating, the filter element can be evenly stressed, avoiding the situation of eccentricity during rotation due to uneven stress on the filter element, which affects the normal disassembly of the filter element. There is a small amount of volatile liquid in the environment where the filter element is installed inside the coalescing filter. Close contact poses a potential health hazard to the human body. Therefore, it is necessary for the user to operate the rotation of the hook head 3 at a certain distance to disassemble the filter element. At the same time, the plurality of hook-shaped structures 31 on the hook head 3 provide a plurality of fixed points between the hook head 3 and the filter element. After each hook-shaped structure 31 hooks the clamping key on the filter element, the relative position between the filter element and the hook head 3 is completely fixed. The tool can drive the movement of the filter element by driving the movement of the hook head 3, realizing the handling of the filter element. The hook head 3 is connected with an extension rod 2. The user can operate the rotation of the hook head 3 through the extension rod 2, so that the user can disassemble the filter element at a certain distance from the disassembly position of the filter element, avoiding the situation that the harmful substances in the filter element installation environment cause damage to the staff. A handle 1 is also fixed to the end of the extension rod 2 away from the hook head 3. The handle 1 is in a rod-shaped structure. The extension rod 2 is fixed at the midpoint of the handle 1. When the user uses it, both hands hold the two ends of the handle 1 respectively, forming a labor-saving lever with the extension rod 2 located at the midpoint of the handle 1, making it easier for the user to loosen the filter element and realize disassembly. When the filter element is completely loosened, the user can directly pull out the filter element by pulling. The disassembly efficiency is high, and during the disassembly and transportation of the filter element, the user does not need to approach the working environment of the filter element, which is suitable for the user to load and unload the filter element in a dangerous working environment.

[0026] As Figure 2 shown, the hook head 3 is a cylindrical tubular structure. One end of the hook head 3 is fixedly connected to the extension rod 2, and hook-shaped structures 31 are provided on the tube wall at the other end of the hook head 3. The cylindrical tubular structure of the hook head 3 is similar to the shape of a steel pipe. The hook head 3 can be directly processed and made of a steel pipe, which is beneficial to reducing the manufacturing cost. At the same time, the hook-shaped structures 31 are directly opened on the tube wall of the hook head 3. Compared with adding hook-shaped structures 31 outside the hook head 3, the connection is more stable and materials are saved.

[0027] As Figure 2As shown, the hook structure 31 includes a fixing slot 311. The fixing slot 311 is an "L"-shaped structure. The "L"-shaped structure includes a vertical portion arranged along the axial direction and a horizontal portion arranged along the circumferential direction. One end of the vertical portion is communicated with one end of the horizontal portion, and the other end of the vertical portion extends to the lower end surface of the hook head 3. When installing or disassembling the filter element, the key on the filter element can enter the hook structure 31 through the communication part between the vertical portion of the fixing slot 311 and the lower end surface of the hook head 3, and finally reach one end of the horizontal portion of the fixing slot 311 away from the vertical portion. After the key reaches this position, it is wrapped by the fixing slot 311 in three directions, restricting the movement of the key in three directions, playing a fixing role, and at the same time not affecting the key to be taken out of the fixing slot 311 along the original path.

[0028] As Figure 2 shown, a pulling slot 312 is also provided on the upper side of one end of the horizontal portion away from the vertical portion. Since the rotation direction when installing the filter element is different from that when disassembling, a structure is also required to be provided in the fixing slot 311 to restrict the key from sliding out of the fixing slot 11 along the original path to adapt to the rotation requirements in different directions for installing and disassembling the filter element. When installing the filter element, the hook head 3 hooks the key on the filter element and transports the filter element to the installation position. When the filter element reaches the installation position, the filter element abuts against the connection base, and the user continuously extends the tool towards the connection base direction, so that the key on the filter element enters the pulling slot 312. At this time, no matter which direction the user rotates the tool, the key on the filter element will abut against the slot wall on one side of the pulling slot 312, thereby restricting the key on the filter element from sliding out of the fixing slot 311.

[0029] As Figure 2 shown, a pulling slot 313 is also provided on the lower side of one end of the horizontal portion away from the vertical portion. When it is necessary to disassemble the filter element, the key on the filter element is snapped into the end of the horizontal portion, and then the user pulls out the tool outward. Since the filter element has not been completely disassembled at this time and the filter element is still restricted by the connection base and cannot move, the key slides into the pulling slot 313. At this time, no matter which direction the user rotates the tool, the key on the filter element will abut against the slot wall on one side of the pulling slot 313, thereby restricting the key on the filter element from sliding out of the fixing slot 311.

[0030] Embodiment 2

[0031] This embodiment is similar to the above Embodiment 1, the difference is that, as Figure 1As shown, a connecting member 4 is further provided between the extension rod 2 and the hook head 3. In order to ensure that the hook head 3 rotates at the same speed in all directions during the rotation of the tool, the extension rod 2 should be fixed on the central axis of the hook head 3. Since the hook head 3 is a cylindrical tubular structure, there is no structure on the central axis of the hook head 3 for connecting with the extension rod 2. A connecting member 4 is provided between the extension rod 2 and the hook head 3. The connecting member 4 straddles above the hook head 3, and the extension rod 2 is fixed on the central axis of the hook head 3 through the connecting member 4, ensuring that all parts of the hook head 3 rotate at the same speed when the extension rod 2 drives the hook head 3 to rotate.

[0032] As Figure 2 shown, the connecting member 4 includes a horizontal portion 41. The horizontal portion 41 is fixedly connected to the extension rod 2. Both ends of the horizontal portion 41 are connected with bending portions 42. The bending portions 42 bend towards the direction of the hook head 3. One end of the bending portion 42 away from the horizontal portion 41 is fixedly connected to the hook head 3. The horizontal portion 41 is parallel to the end face of the extension rod 2, so that there can be a larger contact area between the extension rod 2 and the connecting member 4. The bending portions 42 bend towards the direction of the hook head 3, increasing the length of the tool, enabling the user to load and unload the filter element at a farther position.

[0033] As Figure 2 shown, one end of the bending portion 42 connected to the hook head 3 bends to form a second horizontal portion 43. The bottom surface of the second horizontal portion 43 is a horizontal plane, and the horizontal plane is fixedly connected to the hook head 3. The second horizontal portion 43 is parallel to the end face of the hook head 3 and has a larger contact area with the end face of the hook head 3, making the connection between the connecting member 4 and the hook head 3 more stable.

[0034] Embodiment 3

[0035] This embodiment is similar to the above Embodiment 1, except that, as Figure 2 shown, a gap 5 for facilitating the observation of the working condition of the hook head 3 is formed between the connecting member 4 and the hook head 3. The user can observe through the gap 5 whether the key on the filter element is hooked into the hook-shaped structure 31.

[0036] As Figure 1 shown, the extension rod 2 is made of steel. The steel material has the characteristics of being household and having high structural strength and not being easily deformed, and can withstand the torque during the rotation of the tool and the load during the transfer of the filter element.

[0037] Obviously, the above embodiments of the present utility model are merely examples for clearly explaining the present utility model, and are not limitations on the implementation manners of the present utility model. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present utility model shall be included within the protection scope of the claims of the present utility model.
