Description

Technical Field

[0001] The utility model relates to the technical field of water purification equipment, in particular to a filter provided with a filter element skeleton. Background Art

[0002] The laminated filter is a commonly used filtering equipment. The laminated net is composed of a large number of thin, fine-textured sheets overlapped, and locked into a cylindrical filter element by the end cap and the filter element skeleton. The filter element skeleton has large holes on the basic side, allowing water to flow through, thereby realizing the filtration or backwashing channel. During filtration, the laminate is locked by the filter element skeleton and the end cap through springs and mechanical structures, and water flows from the outside to the inside. The laminate intercepts floating objects, rust, silt and other granular debris in the water. During backwashing, the laminate is loosened, and water flows out from the inside to the outside, washing away floating objects, rust, silt and other granular debris attached to the laminate. However, there are large holes on the side of the filter element skeleton, and the water flow from the inside to the outside is relatively dispersed, and it is impossible to form a high-pressure water flow to impact the granular debris on the laminate. The gap between the laminates becomes larger after long-term accumulation, so that the filtration accuracy cannot reach the expected effect, affecting the service life of the filter, and bringing a bad experience to consumers.

At this time, the water distributor blocks the second through hole, and the water flows through the first through hole into the space between the stack and the filter bottle. After being filtered by the stack, the water enters the inner frame through the first water through hole and the second water through hole. The water flows upward from the inner frame through the two-way pipe and then flows out from the water outlet pipe.

The inner frame moves downward so that the second through hole and the water diversion piece are offset, and the retaining ring moves downward with the inner frame to close the first through hole; water flows from the water inlet pipe into the channel between the middle piece and the two-way pipe. Since the first through hole is closed and the second through hole is opened, water flows through the second through hole into the inner frame, and the second water hole is connected with the small hole. After the water flows through the second water hole and the small hole, the stacking is flushed. The water flows into the space between the stacking and the filter bottle and then flows out from the sewage discharge shaft.
