Description

Technical Field

[0001] This utility model relates to the technical field of water treatment equipment maintenance tools, specifically, to a quick-installation and removal tool for filter membranes in water treatment production equipment. This tool is particularly suitable for disassembling and installing filter membranes within the confined space of pipework in water treatment equipment, aiming to improve the maintenance efficiency and operational safety of water treatment equipment while reducing potential damage to the equipment. In water treatment technology, filter membranes, as core components, are widely used in the separation, concentration, and purification processes of substances, and their performance directly affects the water treatment effect. Therefore, developing a simple and effective disassembly tool to improve the replacement and maintenance process of filter membranes in water treatment equipment is an important development direction in this technical field. Background Technology

[0002] In the maintenance and operation of water treatment equipment, regular replacement and repair of filter membranes are crucial steps to ensure water quality and equipment performance. As a core component of water treatment equipment, the performance of the filter membrane directly affects the water treatment effect. However, in existing water treatment equipment, filter membranes are usually installed inside the equipment pipelines, where the space is limited, restricting the operating space for maintenance personnel. When filter membrane replacement or repair is needed, the confined space inside the pipelines prevents personnel from directly entering to disassemble and move the membrane, causing significant inconvenience to maintenance work.

[0003] Currently, construction workers commonly use wire hooks to replace and repair filter membranes. This method not only requires multiple people working together, increasing the complexity and time consumption of the operation, but also obstructs the view during the operation, making it difficult for workers to clearly observe the internal conditions of the pipeline, resulting in inaccurate operation and poor reliability of the maintenance work. In addition, because the sudden force or release of force on the waist and arms is required during the removal of the filter membrane, it is easy to cause sprains and bumps to the workers, increasing personal safety risks.

[0004] In addition to the problems mentioned above, traditional disassembly methods also include tapping the filter membrane from one side with a tool to push out the cylindrical membrane. However, this method may damage the water treatment equipment during the tapping process, and due to the unpredictability of the tapping, it is difficult to remove the cylindrical filter membrane. More seriously, the fragments generated by the tapping may enter the machine, affecting the normal operation of the equipment, and even causing serious damage to the equipment in some cases.

[0005] Therefore, existing technologies have significant limitations in the replacement and maintenance of filter membranes in water treatment equipment. A new solution is urgently needed to address these problems, improve operational efficiency and safety, and reduce potential damage to the equipment. This invention aims to solve these technical problems by providing a simple and effective disassembly tool to improve the replacement and maintenance process of filter membranes in water treatment equipment. Utility Model Content

[0006] In view of the aforementioned shortcomings of existing maintenance technologies, this utility model provides a tool suitable for disassembling and assembling filter membranes within the confined space of water treatment equipment. This tool is simple in design and easy to operate, allowing for flexible insertion and extraction, making the hooking, replacement, and installation of heavy filter membranes within the narrow piping space of water treatment equipment more efficient. Using this tool can significantly save time and labor, improve work efficiency, reduce the labor intensity of construction workers, and effectively prevent damage to equipment or injury to personnel during disassembly, thereby ensuring the safety of the construction process and reducing operational risks.

[0007] To solve the above technical problems, this utility model is achieved through the following technical solution:

[0008] This utility model discloses a filter membrane disassembly and assembly tool suitable for narrow pipe spaces in water treatment filtration equipment. The tool includes a pull head assembly, characterized in that the pull head assembly consists of a positioning support and a positioning tip with its bottom end installed through the positioning support. A hook is provided on the positioning support on the same side as the top of the positioning tip.

[0009] As an alternative, the hook includes a first hook disposed on one side of the positioning tip and a second hook disposed on the other side.

[0010] As an alternative, the bottom end of the positioning tip is fixedly connected to a connector.

[0011] As an alternative, a pull rod is also included, wherein the two ends of the pull rod are provided with a first pull rod joint and a second pull rod joint, wherein the first pull rod joint is detachably installed on the joint by a clamp.

[0012] Alternatively, the pull rod may be one or more.

[0013] Alternatively, the bottom end of the positioning tip is installed through the positioning support at approximately the center position.

[0014] As an alternative, the positioning support is provided with a sliding component.

[0015] As an alternative, the first hook and the second hook may be one or more.

[0016] As an alternative, the claws of the first hook and the second hook are arranged in roughly opposite directions.

[0017] Alternatively, the pull head assembly and pull rod may be made of stainless steel.

[0018] As an alternative, the sliding component can be a pulley or a bearing.

[0019] This invention is simple, practical, and convenient. It utilizes a vertical positioning support on the tool's pull head as a support point. The pull rod and pull head assembly are detachably connected and assembled via clamps. During operation, the operator reciprocates by pulling the disassembly tool in a linear motion, causing the tool's pull head assembly to engage with the filter membrane end cap. Rotating the pull rod allows the hook of the pull head assembly to engage with the filter membrane end cap, thus pulling out the filter membrane from the narrow pipe space of the water treatment equipment. The vertical positioning support prevents direct contact between the tool's pull head assembly and the narrow pipe space of the water treatment equipment, reducing friction. The disassembly process is convenient, quick, safe, and reliable, without damaging the narrow pipe space or the cylindrical filter membrane of the water treatment equipment. This effectively solves the problem of equipment damage during filter membrane removal, safely and reliably reducing construction risks.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. This utility model is simple to operate and easy to use. It can be flexibly stretched and pulled out. The heavier filter membrane can be replaced and installed in the narrow pipeline space of the water treatment filtration equipment by stretching. It saves time and effort, improves work efficiency, reduces the burden on construction personnel, and reduces construction risks.

[0022] 2. The disassembly tool provided by this utility model is suitable for use in narrow pipe spaces. It has multiple tool heads that can be flexibly replaced to improve utilization.

[0023] 3. The pull rod of this utility model can be freely assembled according to actual needs to achieve different length adjustments, which can meet the actual operation requirements of different working conditions.

[0032] To make the technical means, inventive features, achieved objectives, and effects of this utility model readily understandable, the following detailed illustrations further illustrate the present utility model. However, the present utility model is not limited to the embodiments described below. It should be understood that the structures, proportions, sizes, etc., depicted in the accompanying drawings are merely for illustrative purposes and to aid those skilled in the art in understanding the content disclosed herein. They are not intended to limit the implementation conditions of the present utility model and therefore have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by the present utility model, should still fall within the scope of the technical content disclosed in the present utility model.

[0033] Meanwhile, the terms such as "upper", "lower", "left", "right", "middle", "first", and "second" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] like Figure 5 As shown, during operation, industrial water treatment filtration equipment may encounter a large amount of suspended solids, particulate matter, organic matter, and grease in the water. These impurities can clog the micropores of the filter bags, leading to a decrease in filtration efficiency. Therefore, it is necessary to regularly replace and maintain the filter membranes in the industrial water treatment filtration equipment. The water treatment filtration equipment consists of several long pipes, and several cylindrical filter membranes are distributed within the narrow space of these long pipes. The filter membranes are heavy and numerous, making disassembly inconvenient.

[0036] Because the pipeline space for installing filter membranes in industrial water treatment filtration equipment is limited, the filter membrane needs to be removed from the pipeline when the construction personnel disassemble it. Depending on the length of the pipeline of the water treatment filtration equipment, one or more filter membrane assemblies 4 are installed in the pipeline. Filter membrane assembly 4 is provided with filter membrane end caps 5 at both ends. The end caps 5 are generally circular in structure. A fixing ring 501 is provided on the outermost ring of the end cap 5 for fixing and sealing the filter membrane. The center of the end cap 5 is provided with a center hole 502 for installing and removing the filter membrane, which is coaxial with the fixing ring 501. Multiple spoke-shaped end cap components 503 are provided along the outer periphery of the center hole 502 in the direction of the fixing ring 501 to support the filter membrane and the end cap 5 and distribute the load to make the filter membrane more stable. Meanwhile, to facilitate the removal of the filter membrane assembly 4 from the filtration equipment pipeline, one or more loading and unloading grooves 504 are provided on the spoke-shaped end cap component 503 near the middle of the inner side of the filter membrane. The loading and unloading grooves 504 can be one or more; for example, one loading and unloading groove 504 can be provided at the exact center of multiple spoke-shaped end cap components 503 near the inner side of the filter membrane, or multiple loading and unloading grooves 504 can be provided to form a serrated loading and unloading strip. Alternatively, loading and unloading grooves 504 can be provided on the inner side of each spoke-shaped end cap component 503, or they can be provided only on the inner side of some spoke-shaped end cap components 503, such as spaced out on alternating end cap components 503 or spaced apart between two end cap components 503. Any arrangement that satisfies the purpose of replacing and repairing the filter membrane using the filter membrane removal and installation tool of this utility model is acceptable.

[0037] like Figure 1As shown, this embodiment provides a filter membrane disassembly tool suitable for use in narrow pipe spaces in water treatment filtration equipment. It includes a pull head assembly 1 and one or more tool pull rods 2 that can be flexibly installed. The pull head assembly 1 has a positioning tip 101 with a tapered protrusion at the top, which cooperates with the center hole 502 of the end cap of the filter membrane assembly to position the disassembly tool and the filter membrane. The bottom end of the positioning tip 101, opposite to the top end, is inserted through a positioning support 7 perpendicular to the positioning tip 101, and the positioning tip 101 is installed approximately at the center of the positioning support 7. A connector 105 is fixedly connected to the bottom end of the positioning tip 101 extending from the positioning support 7 for detachable connection and installation of the pull rods 2 for extension and expansion.

[0038] like Figure 2 , 3 As shown in Figure 4, one end of the pull rod 2 is provided with a first pull rod connector 201, and the other end is provided with a second pull rod connector 202. The first pull rod connector 201 is detachably connected to the connector 105 of the pull head assembly 1 via a clamp 3. In use, the connector 105 of the pull head assembly 1 is aligned and assembled with the first pull rod connector 201 of the pull rod 2. The clamp 3 is then installed around the connection between the connector 105 and the first pull rod connector 201 for assembly and fixation. Finally, the clamp 3 is tightened with the fastening screw 301 to complete the tight connection and fixation of the pull head assembly 1 and the pull rod 2. Because the inside of the clamp 3's movable groove is an inverted trapezoidal structure, tightening the clamp screw by turning the fastening wrench 302 can make the clamp 3 more tightly and stably fix the connection, forming an integral, non-movable movable connection. The clamp 3 can be implemented using clamp structures commonly used in this field, such as the Kequan brand φ25 stainless steel quick-connect clamp. Furthermore, through the design of the independent connecting rod of this pull rod 2, the number of pull rods 2 can be increased or decreased in actual use according to the specific working scenario and the actual situation and needs on site, thereby forming a long rod disassembly tool to hook and retrieve the filter membranes at different distances inside the narrow pipe of the water treatment equipment.

[0039] Meanwhile, on both sides of the positioning support 7, and in the same direction as the top of the conical protrusion of the positioning tip 101, there are first hooks 601 and second hooks 602 for hooking the filter membrane end cap 5. The free ends of the first hooks 601 and second hooks 602 are provided with claws 603. The claws 603 of the first hooks 601 and second hooks 602 are generally arranged in opposite directions, such as symmetrically arranged at 180 degrees diagonally, or with a slight deviation. However, it is generally advisable that they can be smoothly inserted into the loading and unloading grooves 504. The first hooks 601 and second hooks 602 work together with the loading and unloading grooves 504 provided on the multiple spoke-shaped end cap components 503, so that when replacing and repairing the filter membrane with disassembly and assembly tools, the first hooks 601 and second hooks 602 can be inserted into the loading and unloading grooves 504 provided on the end cap components 503 by rotating the disassembly and assembly tools, so as to more easily remove the filter membrane from the narrow pipe.

[0040] The length of the positioning support 7 is approximately the same as the diameter of the filter membrane end cap, allowing the pull head assembly 1 to move linearly in the pipeline. When the construction worker inserts the pull head assembly 1 into the narrow pipeline of the water treatment filtration equipment, the pull rod 2 is pulled back and forth linearly to pull the pull head assembly 1. The positioning support 7 can cooperate with the inner wall of the pipeline to guide the positioning tip 101 into the center hole 502 of the filter membrane end cap, so that the positioning tip 101 and the center hole 502 of the filter membrane end cap are connected and positioned. Because the end of the positioning tip 101 is a conical protrusion, even if there is a certain range of deviation between the conical protrusion of the positioning tip 101 and the center of the end cap center hole 502, as long as the magnitude of this deviation is less than the radius of the end cap center hole 502, it will not affect the positioning of the positioning tip 101 and the end cap center hole 502. The positioning tip 101 can smoothly enter the end cap center hole 502. After the positioning tip 101 is positioned, the pull rod 2 drives the pull head assembly 1 to rotate simultaneously, so that the first pull hook 601 and the second pull hook 602 accurately hook onto the loading and unloading groove 504 provided on the end cap component 503. Then, by pulling the pull rod 2, the filter membrane can be taken out from the pipeline for replacement and maintenance. In addition, a sliding component 701 can be provided on the positioning support 7. The sliding component 701 can be a pulley or a bearing, etc. The sliding component 701 can be provided at both ends of the positioning support 7, or only at one end of the positioning support 7. The positioning support 7 can have the same sliding component 701 at both ends, or different sliding components 701 at both ends. For example, both ends of the positioning support 7 can be provided with pulleys or bearings, or one end can be provided with a pulley and the other end with a bearing. The setting of similar structures or components that can perform the support and sliding guidance functions of this utility model patent are all intended to be the sliding component 701 described in this patent.

[0041] In this embodiment, the pull head assembly 1 can be made of 304 stainless steel. The rigidity of the steel structure is used to create a disassembly tool with strong load-bearing capacity. The clamp connection structure allows for free assembly and disassembly according to actual needs. Multiple pull rods 2 can be assembled to extend the disassembly tool according to actual working conditions to meet the disassembly needs of filter membranes with different pipeline lengths, thereby enabling flexible replacement and adjustment for different site environments.

It should be noted that the terms "comprising," "including," or any other variations are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
