[0063] 1. Adapt to different functional requirements

[0064] Secondary grid plate 2: located in the distribution tank, mainly for fine filtering of water. The disassembly method adopts the combination of push rod, ratchet plate and locking rack, which is convenient for quick operation and ensures the stability and sealing performance after installation to meet the high requirements of stability in the fine filtering process.

[0065] Primary grid plate 18: located in the processing tower, responsible for coarse filtering. Its disassembly method uses T-shaped handle driving rack and gear linkage, and realizes fixation and release through connecting rope and clamping rod, which is suitable for larger and heavier primary grid plate, and is more labor-saving and safer to operate.

[0066] 2. Optimize operation convenience

[0068] Primary grid plate 18: uses mechanical auxiliary device, reduces the need for direct manual force, especially suitable for large grid plate, reduces the labor intensity of maintenance personnel.

[0069] 3. Improve system stability and durability

[0070] Different disassembly methods are optimized according to the installation position and function of the grid plates, avoiding the possible mismatching problem of a single disassembly method, thereby improving the stability and durability of the entire system.

[0071] The secondary grid plate is designed to be engaged with the locking rack and the ratchet plate, ensuring that it can still be fastened under water pressure; the clamping rod and the clamping groove structure of the primary grid plate provide a stable fixing effect.

[0072] 4. Meet the needs of different maintenance scenarios

[0073] The secondary grid plate is located inside the distribution tank and can usually be directly operated during maintenance, so a relatively simple disassembly method is adopted.

[0074] The primary grid plate is located in the treatment tower and usually needs to handle larger spaces and more complex mechanical structures, so mechanical auxiliary devices such as gears and connecting ropes are used to reduce the limitation on the maintenance space and improve the precision and safety of the operation.

[0075] 5. Clear division of labor, improve efficiency

[0076] By designing disassembly methods according to functional characteristics, the complexity or unsuitability of the disassembly process is avoided, making it possible for maintenance personnel to more efficiently complete the cleaning and replacement tasks of different components.

[0077] Therefore, the secondary grid plate and the primary grid plate use different disassembly methods, which is a comprehensive optimization of functional requirements, operational convenience, system stability, and maintenance scenario adaptability. This differentiated design not only improves the overall system efficiency, but also enhances the safety and reliability of the maintenance process.

[0078] Obviously, those skilled in the art can make various modifications and variations to the present application without departing from the spirit and scope of the present application.
