Abstract
A kind of filtration unit of saving type RO pure water device, the strainer and the counter-osmosis device that comprise the positive backwash craft piping of raw water box, raw water pump, band that is linked in sequence with pipeline, extremely dense water tank upper import of concentrated water discharge pipe coupling with counter-osmosis device, dense water tank lower part outlet is connected to the backwashing pump import, the outlet pipe of backwashing pump is connected to the backwash water import of filter bottom, and the wash water outlet pipe with filter bottom is connected to the raw water box import simultaneously.The dense water conservancy that the utility model directly discharges former counter-osmosis device is used as the backwashing water of strainer, the positive wash-down water of former water with strainer is recovered to raw water box simultaneously, strainer does not just have the former water of consumable like this, reduced the former damage by water consumption of reverse osmosis water purifier production process greatly, save precious water resource, reduced production cost.
Description
Technical field
The utility model relates to a kind of filtration unit, particularly the filtration unit of reverse osmose pure-water preparation facilities Central Plains water pretreatment system.
Background technology
The pretreatment filtering device of reverse osmose pure-water preparation, in use, through after a while, the filtering layer surface in the strainer will deposit last layer impurity, influences filtration efficiency, must regularly clean.The cleaning operation of existing strainer is to adopt former water that back flushing is carried out on the filtering layer surface and just washing, and flushing backlash wash water is directly discharged because of containing a large amount of impurity, thereby strainer needs a part of former water of consumable in process of production.
Summary of the invention
The technical problem that the utility model quasi-solution is determined is, for the saves valuable water resources and reduce production costs, and the filtration unit of existing reverse osmosis water purifier is carried out technological improvement, make the cleaning process of strainer not consume former water, and obtain normal cleaning performance equally.
Technical solution of the present utility model is: it comprises the strainer and the counter-osmosis device of the positive backwash craft piping of raw water box, raw water pump, band that is linked in sequence with pipeline, extremely dense water tank upper import of concentrated water discharge pipe coupling with counter-osmosis device, dense water tank lower part outlet connects the import of backwashing pump, and the outlet pipe of backwashing pump connects the backwash water import of filter bottom.
Also the wash water outlet pipe of filter bottom is connected to the raw water box import simultaneously.
The beneficial effects of the utility model are: counter-osmosis device is directly discharged the backwashing water of the dense water conservancy of depleted as strainer, and the positive wash-down water of former water with strainer is recovered to raw water box simultaneously.Strainer does not just have the former water of consumable like this, has saved precious water resource, has reduced production cost; And proof uses the strainer cleaning performance and the filtered water quality of the utility model technology all normal by analysis.
Description of drawings
Accompanying drawing is the utility model overall structure synoptic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail with embodiment.
Raw water box 4, raw water pump 5, the strainer 7 that is provided with positive backwash craft piping and counter-osmosis device 11 and pure water case 13 are connected with pipeline 6,10,12 orders.Set up dense water tank 1, the concentrated water discharge pipe 14 of counter-osmosis device 11 is connected to the upper inlet of dense water tank 1, dense water tank 1 lower part outlet is connected to the import of backwashing pump 2, the outlet conduit 3 of backwashing pump 2 is connected on the backwash water inlet pipe of strainer 7 bottoms, and the dense water backwash water after the backwash is through delivery pipe 9 dischargings; Simultaneously the wash water outlet pipe 8 of strainer 7 bottoms is connected to the import of raw water box 4; Be equipped with control valve on above-mentioned each connecting tube.
