Description

Technical Field

[0001] This utility model provides a water treatment filter element assembly, belonging to the field of water treatment technology. Background Technology

[0002] Water treatment filter cartridges filter and purify water, ensuring the safety of people's drinking water and making it available for their use.

[0003] Existing water treatment filter cartridges can basically meet normal usage needs. They mainly include an outer shell, a cover set on top of the outer shell, and a filter cartridge placed in the space between the outer shell and the cover. The filter cartridge includes a water guide pipe and a filter layer set outside the water guide pipe. When in use, the water to be treated is added into the space between the outer shell and the cover through the inlet. The water is introduced into the water guide pipe through the layers of the filter layer and flows from top to bottom through the outlet.

[0004] Based on the above research and existing technology, it has been found that when filtering particulate impurities from water resources, a small amount of large particles inevitably exist. Direct filtration through a filter cartridge quickly clogs the cartridge, rendering it unusable. Therefore, the filtration efficiency and lifespan of the filter cartridge need to be improved. Accordingly, this invention provides a water treatment filter cartridge assembly. Utility Model Content

[0005] The technical problem solved by this utility model is that when filtering directly through a filter element, a small amount of large particulate impurities accumulate and quickly clog the filter element, rendering it unusable. The filtration effect needs to be improved, and the service life of the filter element needs to be extended.

[0006] To solve the technical problem, the technical solution provided by this utility model is as follows: a water treatment filter cartridge assembly, including a shell and a cover set on the top of the shell, a filter cartridge is provided inside the shell, a water inlet is provided on the top of the cover, a support ring is provided on the top of the cover outside the water inlet, a filter cylinder is threadedly connected to the inner side wall of the support ring, a cross brace is provided between the inner upper walls of the filter cylinder, a rotating rod is rotatably connected to the cross brace, a fan blade is provided at the top of the rotating rod, an L-shaped plate is symmetrically provided on the lower end of the rotating rod, and a scraper is provided on the vertical side wall of the L-shaped plate that fits against the inner side wall of the filter cylinder.

[0007] Furthermore, the top of the inner wall of the cover is provided with an internal thread, and the top of the outer wall of the outer shell is provided with an external thread that matches the internal thread.

[0008] Furthermore, a sealing ring is provided on the top of the outer casing.

[0009] Furthermore, the bottom of the outer casing is provided with a water outlet located at the bottom of the filter element, and the bottom side wall of the outer casing is provided with a drain outlet. Both the drain outlet and the water outlet are provided with control valves.

[0010] Furthermore, the fan blades are positioned above the cross brace, the L-shaped plate is positioned below the cross brace, and the filter cartridge sidewall is provided with multiple filter holes positioned below the cross brace.

[0011] Furthermore, the cross brace is provided with a bearing at its center that is rotatably connected to the rotating rod.

[0012] Furthermore, the filter element includes a water guide pipe and a filter layer disposed outside the water guide pipe, the filter layer including a reverse osmosis (RO) membrane and a water guide membrane disposed between the reverse osmosis (RO) membranes.

[0013] The beneficial effects of this utility model are as follows: large particles of impurities are initially filtered out by the filter cartridge. When the water flows, the fan blades rotate, which in turn causes the scraper to rotate around the rotating rod, thus removing the particles of impurities attached to the filter holes to prevent them from clogging the filter holes and affecting the water treatment effect. Water resources mixed with small particles of impurities are then filtered through the filter cartridge, which can effectively improve the service life of the filter cartridge and greatly improve the filtration effect.

[0027] The principle of this utility model

[0028] In use, the water to be treated flows into the filter cartridge 5 through the inlet 12. Water mixed with small particles of impurities flows from the filter holes 11 into the outer shell 1 from top to bottom. Large particles of impurities remain in the filter cartridge 5. When the water flows, it drives the fan blade 8 to rotate, which in turn drives the rotating rod 7 to rotate, which in turn drives the L-shaped plate 9 and the scraper 10 to rotate around the rotating rod 7. The scraper 10 can remove the particles of impurities attached to the filter holes 11 to prevent them from clogging the filter holes 11 and affecting the water treatment effect. Water mixed with small particles of impurities is introduced into the water guide pipe 19 through the water guide holes after passing through the layers of the filter layer 20. It flows from top to bottom and is discharged through the outlet 16. There is no need to filter large particles of impurities through the filter element 3, which can effectively improve the service life of the filter element 3 and greatly improve the filtration effect.
