AI Technical Summary
Technical Problem
Existing disc pre-filters have low flow rates and complex structures, making it difficult to efficiently clean impurities between the discs, resulting in decreased filtration efficiency.
Method used
A high-flow-rate disc backwashing pre-filter was designed. By controlling the opening and closing of the drain hole and the direction of water flow, the discs can be automatically cleaned. The filter includes a combination of filter bottle, valve head, mounting bracket, water distribution tank and switching components. The filter is flushed with water flow to switch between filtration and backwashing.
Benefits of technology
This improves the filter's lifespan and filtration efficiency, ensures clean discs, and maintains high-efficiency filtration performance.

Abstract
This utility model discloses a high-flow-rate disc backwashing pre-filter, relating to the field of pre-filter technology. It includes a valve head connected to the filter, the valve head's inner cavity having a partition separating the filter bottle port into a first port and a second port; a mounting bracket slidably disposed within the filter bottle's inner cavity, the mounting bracket having a retaining ring on its outer periphery near the valve head, the retaining ring capable of sealing the second port; a water inlet groove on the upper side wall of the mounting bracket; several discs fitted around the outer periphery of the mounting bracket; and several flushing holes communicating with the water inlet groove; a water distribution groove disposed between the filter bottle port and the mounting bracket, the bottom surface of the water distribution groove having several water distribution holes, each corresponding to the retaining ring; and a switching component for controlling the axial sliding of the mounting bracket. This high-flow-rate disc backwashing pre-filter solves the technical problem of existing pre-filters where, after long-term use, debris accumulates between the filter discs, and the small gaps between the discs make cleaning difficult, leading to filter failure.
