TDS is the english acronym for Total Dissolved Solids (Total Dissolved Solids) and refers to the concentration of Total Dissolved Solids in water. TDS values are generally used to measure the purity of purified water.
Reverse Osmosis membrane cartridges (RO) are membrane separation filtration cartridges that use osmotic pressure differentials as the motive force. Because the RO membrane aperture is little, under certain pressure, the hydrone can pass through the RO membrane, and inorganic salt, heavy metal ion, organic matter, colloid, bacterium, virus's the impurity in the source aquatic can't pass through the RO membrane to through reverse osmosis membrane filters, can separate pure water and the concentrate that can't permeate the RO membrane promptly strictly.
The RO membrane is in an operating state when installed in the filter cartridge. The raw water, the proportion of waste water in filter core system is far greater than the pure water, the complete machine is shut down the back, the solenoid valve of intaking is closed, the RO filter core forms a confined space, waste water and filter core inside wall and RO membrane waste water end (the RO filter core forms a confined space) in the membrane area in the filter core can mix with the raw water in the filter core and dilute, the TDS of the end of intaking (the water pump to the water route of raw water inlet 101) in whole filter core like this is very high, when waiting to start the machine once more, the solenoid valve of intaking is opened, under the effect of pressure, this part of high TDS value water that deposits in the filter core can filter earlier, because the TDS value of intaking improves, the pure water TDS value of natural restart is just high, so general first cup of water is not advised to drink.
In the related art, a reverse osmosis membrane filter element, which is a filter element for filtering water using a reverse osmosis membrane to obtain pure water, is provided in a water purifier to filter tap water. However, the first water solution of the vertically placed reverse osmosis membrane filter element is not applicable to the whole reverse osmosis membrane filter element placed laterally, namely when the traditional reverse osmosis membrane filter element is placed laterally, the problem that the TDS value of the first water is high still exists.
Referring to fig. 1 and 2, the present invention provides an embodiment of a side-laid reverse osmosis membrane filter cartridge for filtering raw water to produce pure water. In the following embodiments, the following description will be mainly given by taking an example of the application to a water purifier, and other cases requiring a side-release reverse osmosis membrane filter element can be referred to.
Referring to fig. 1 to 7, in an embodiment of the side reverse osmosis membrane filter element according to the present invention, the reverse osmosis membrane filter element includes a housing 100, a reverse osmosis membrane element 200, and a first end cap assembly 300, wherein the housing 100 has a first end and a second end along a length direction thereof, the housing 100 is provided with an installation cavity, and the first end is provided with a raw water inlet 101, a concentrated water outlet 102, and a pure water outlet 103 which are communicated with the installation cavity; the reverse osmosis membrane element 200 is installed in the installation cavity, the reverse osmosis membrane element 200 comprises a central pipe 210 and a membrane unit 220 arranged on the periphery of the central pipe 210, the membrane unit 220 is communicated with the raw water inlet 101 and the concentrated water outlet 102, and the central pipe 210 is communicated with the pure water outlet 103; the outer peripheral wall of the reverse osmosis membrane element 200 and the inner peripheral wall of the shell 100 are enclosed to form a pressure maintaining water storage chamber 201, and the pressure maintaining water storage chamber 201 is communicated with the central pipe 210; the first end cap assembly 300 is disposed at the second end, the first end cap assembly 300 is provided with a first diversion channel 301 communicated with the central pipe 210, and a second diversion channel 302 extending downwards from the end of the first diversion channel 301, and the second diversion channel 302 is communicated with the pressure-maintaining water storage chamber 201.
Specifically, the reverse osmosis membrane element 200 may be installed in the installation cavity of the housing 100 by a sealing member such as a gasket or sealant. It should be noted that the pressure-maintaining water storage chamber 201 is only communicated with the central pipe 210, and other positions are all in a closed structure.
The housing 100 of the reverse osmosis membrane filter element may be composed of a bottle body 110 and a bottle cap 120, the bottle body 110 has a bottle mouth, the bottle cap 120 is disposed on the bottle mouth, the bottle cap 120 may have a plurality of taps to form a raw water inlet 101, a concentrated water outlet and a pure water outlet 103, the tap corresponding to the raw water inlet 101 may have an electromagnetic valve, and the raw water may be pumped into the reverse osmosis membrane filter element by setting a booster pump.
It can be appreciated that the side-loading reverse osmosis membrane cartridge needs to be horizontally positioned when installed. When the side-put type reverse osmosis membrane filter element works and a tap communicated with the pure water outlet 103 is opened, the side-put type reverse osmosis membrane filter element filters raw water, most of pure water initially flows out of the pure water outlet through the central pipe 210, a small part of pure water flows into the pressure-maintaining water storage chamber 201 through the central pipe 210, and when certain pure water is stored in the pressure-maintaining water storage chamber 201, all pure water prepared by the reverse osmosis membrane element 200 at this time flows out of the pure water outlet 103 from the central pipe 210 and finally flows out of the pure water tap.
When the side-put type reverse osmosis membrane filter element stops working, a water tap communicated with the pure water outlet 103 is closed, but the booster pump still continues working, all the produced pure water flows into the pressure maintaining water storage chamber 201 at the moment, the air in the pressure maintaining water storage chamber 201 is compressed, and when the pressure of the air reaches a set value of the high-pressure switch, the high-pressure switch sends a signal to control the booster pump and the electromagnetic valve. Because the booster pump is closed, make the pressure of membrane unit 220 middling water reduce, and because under the effect of the pressure maintaining reservoir 201's air and the pure water of pressure maintaining reservoir 201's gravity, the pure water of pressure maintaining reservoir 201 flows back to in center tube 210 and the membrane unit 220 through second water conservancy diversion passageway 302 and first water conservancy diversion passageway 301, thereby the dense water of extrusion membrane unit 220 is discharged from dense water discharge mouth 102, make the occupation ratio of whole side formula reverse osmosis membrane filter core dense water after the stop work minimum, thereby make the ionic balance in the side formula reverse osmosis membrane filter core, when the next start-up, the TDS value of initial raw water is lower, and then it is lower to make the TDS value of first cup pure water when the start-up.
