Abstract
The invention relates to a flat membrane water purification apparatus with a flushing structure, and a technology thereof. The apparatus is arranged on a water pipeline to purify and filter inlet water. The apparatus adopts a flat micro-filtration membrane as a filtration assembly to purify and filter the inlet water, so particle impurities with the diameters of 0.1-0.5mum can be removed. Problems comprising low filtration precision, bad organic matter and turbidity removal effects, high addition cost of a coagulant and the like of routine pre-positioned water purification apparatuses adopting PP cotton (a polypropylene melt-blown material) or a stainless steel filter screen are solved; and compared with hollow fiber membranes, the apparatus has the advantages of strong pollution resistance, long service life, enough strength, long-term stable operation and the like. The apparatus has a manual back-flushing function, so the flow channel direction of water can be changed through rotating a top back-flushing adjustment handle, the water permeates from the outer cavity of the membrane into the flat membrane for filtration, impurities on the surface of the membrane are cleaned through the rotation water of the adjustment handle, and the water is discharged through a sewage discharge port. The surface of the membrane can be wiped through a pollution discharge scraper plate, so the impurities adhered on the surface of the membrane can be effectively removed, and the cleaning effect is enhanced.

Device has the manual backwashing function, regulates the runner trend that handle changes water by the rotating tip backwash, and when normally using, water is filtered through Flat Membrane by the exocoel of film, cleans the film surface impurity by regulating the handle rotating water, and water is discharged by sewage draining exit.And the blowdown scraper plate can carry out wiper to the film surface, and the impurity that sticks to the film surface is effectively removed, and strengthens cleaning performance.
The technical scheme that its technical problem of the novel solution of the present invention adopts is: a kind of Flat Membrane water treatment technology and device with flushing mechanism, comprise valve body, valve body has water inlet and delivery port, two ends are connected with respectively regulates handle and housing, described housing bottom is provided with the blowdown mouth, be coaxially arranged with filter cylinder in the described housing, described filter cylinder sealing arranges, described water inlet is connected with cartridge interior, described delivery port is connected with enclosure interior, and described filter cylinder inwall is coated with Flat Membrane, and the interior coaxial setting of filter cylinder turns takes out, described rotating shaft is passed valve body and is connected with the adjusting handle, be provided with the blowdown scraper plate in the rotating shaft, described blowdown scraper plate and Flat Membrane inwall are interdependent, and described filter cylinder bottom is fixedly connected with drain plug, described drain plug is connected with the blowdown mouth, is provided with sealing device between drain plug and the blowdown mouth.
The present invention is novel to have following innovative point:
(1), the novel use polyether sulfone of the present invention Flat Membrane is as the core filtering material of the preposition filtration in family expenses water inlet manifold road, filtering accuracy is high, contamination resistance by force, easy fracture not.
(2), the novel use screw of the present invention back-flushing structure can change current deflecting, regularly can be with the impurity blowdown of filtering.
(3), the novel blowdown scraper plate that used of this explanation, can be when backwash wiper film surface, increase cleaning performance.
