Description

Technical Field

[0001] This utility model belongs to the technical field of water treatment equipment maintenance tools, specifically relating to a tool for disassembling and assembling a security filter element. Background Technology

[0002] Security filters are key pre-treatment devices in water treatment systems, used to remove tiny particulate impurities from water. During long-term operation, the filter element inside the security filter gradually becomes clogged due to trapped impurities, leading to increased pressure difference between the filter inlet and outlet and decreased water flow. At this point, the filter element must be replaced. In actual disassembly and assembly, the filter element is difficult to remove easily due to vacuum adhesion between it and the filter tank wall, or due to jamming caused by accumulated impurities and scale. Existing disassembly and assembly methods mainly rely on manual operation, usually requiring multiple maintenance personnel to work together, using simple tools such as pry bars to forcibly pull out the filter element. This process is not only labor-intensive and inefficient, but also easily damages the filter element. Therefore, there is an urgent need for a specialized tool that is simple in structure, safe to operate, and efficient and labor-saving to solve the problem of difficult disassembly and assembly of security filter elements. Utility Model Content

[0003] This utility model provides a tool for disassembling and assembling a security filter element to solve the problems mentioned above.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A tool for disassembling and assembling a security filter element includes a screw, on which two nuts are fitted. A support beam is movably mounted between the two nuts on the screw. Support rods are mounted at both ends of the support beam. The upper ends of the support rods abut against the end face of the security filter. A rotating seat is rotatably mounted on the top of the screw. At least three grippers are hinged to the outer circle of the rotating seat. The hooks of the grippers hook onto the outer edge of the security filter element.

[0006] Furthermore, a handle is provided at the bottom end of the screw, and rotating the handle drives the screw to rotate.

[0007] Furthermore, the handle is covered with an anti-slip rubber layer.

[0008] The beneficial effects of this utility model are:

[0009] 1. This utility model utilizes a screw drive to achieve smooth assembly and disassembly of the filter element, avoiding damage to the filter element that may be caused by brute force operation; the frame structure composed of the support beam and support rod provides stable support for the assembly and disassembly work, ensuring the reliability of operation, reducing the filter element damage rate and safety hazards, and improving the assembly and disassembly efficiency; the design of the gripper ensures the stability and uniformity of clamping, avoiding damage to the filter element due to unstable clamping or uneven force.

[0010] 2. A handle is provided at the bottom end of the screw. Rotating the handle drives the screw to rotate, which makes it convenient for the operator to apply force, realize labor-saving operation, reduce labor intensity, and improve work efficiency.

[0011] 3. The handle is covered with an anti-slip rubber layer to increase friction, improve grip stability, prevent hand slippage during operation, and ensure operational safety. Attached Figure Description

[0014] 1. Support beam; 2. Support rod; 3. Screw; 4. Nut; 5. Clamp; 6. Handle; 7. Rotating seat. Detailed Implementation

[0015] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown, a security filter element disassembly and assembly tool is mainly composed of a support beam 1, support rods 2 fixed at both ends thereon, a screw rod 3 threadedly connected to a nut 4 on the support beam 1, a rotating seat 7 connected to the top of the screw rod 3, and a gripper 5 mounted on the rotating seat 7.

[0017] The support beam 1 and the support rod 2 together form a stable support frame. During use, the upper end of the support rod 2 rests smoothly against the end face of the security filter tank, providing a stable support platform and a solid reaction force fulcrum for the installation and removal of the filter element, ensuring stability and balance during the installation and removal process.

[0018] A through hole is made at the center of the support beam 1. The screw 3 passes through this through hole and is threadedly engaged with nuts 4 fixed at both ends of the through hole. The two nuts limit the position of the support beam on the screw, ensuring that the screw 3 can rotate stably and generate axial tension. A handle 6 is connected to the bottom end of the screw 3. The operator can drive the screw 3 to rotate by rotating the handle 6, thereby realizing the installation and removal of the filter element. The handle 6 can be made of aluminum alloy and covered with anti-slip rubber to provide a good grip. The anti-slip rubber layer can effectively prevent the hand from slipping during operation and improve the safety of operation.

[0019] A rotating seat 7 is rotatably mounted on the top of the screw 3. At least three grippers 5 are hinged to the outer circumference of the rotating seat 7. The hook ends of the grippers 5 are used to engage with the outer edge of the filter element of the security filter. In this embodiment, the grippers 5 are made of 65Mn spring steel, possessing excellent elasticity and strength, providing a maximum clamping force of not less than 500N, and are compatible with various filter elements with outer diameters ranging from φ50mm to φ100mm. The grippers 5 and the rotating seat 7 are hinged, allowing the grippers 5 to automatically adjust their angle when clamping the filter element, thus adapting to filter elements of different diameters. The rotating seat 7 and the screw 3 are rotatably connected, preventing torque from being generated on the filter element during screw 3 rotation, thereby avoiding damage to the filter element and ensuring that the pulling process is always an axial linear motion.

[0020] When using this utility model, first, the upper end of the support rod 2 is placed steadily against the end face of the security filter tank to ensure the tool is stable. Then, the claws of the gripper are hooked onto the outer edge of the security filter element. Next, the handle 6 is rotated to drive the screw 3 to rotate, the gripper 5 retracts and grips the filter element. The screw 3 drives the rotating seat 7 to move upward through the nut 4, thereby pulling the filter element out of the security filter. The operator rotates the handle 6 in the opposite direction to open the gripper 5 and remove the device.

[0021] This utility model provides a highly efficient, safe, labor-saving, and effective tool for disassembling and assembling security filter cartridges through ingenious mechanical structure design. It significantly reduces the labor intensity of disassembly and assembly personnel, improves the efficiency and safety of filter cartridge replacement, and reduces equipment damage caused by improper operation. Therefore, this device has good practicality.
