Detailed description of the invention
The exemplary embodiments embodying feature & benefits of the present invention will describe in detail in the following description.Be understood that the present invention can have various changes in different embodiments, it neither departs from the scope of the present invention, and explanation wherein and accompanying drawing are the use when explain in itself, and is not used to limit the present invention.
Embodiments provide a kind of filter, filter of the present invention has reverse osmosis membrane filter element of the present invention, and reverse osmosis membrane filter element of the present invention is applied to filter.
The reverse osmosis membrane filter element 1 of the embodiment of the present invention as depicted in figs. 1 and 2, comprises filtering body 10.This filtering body 10 can be tubular structure, and inside is provided with the material 11 of water treatment.As shown in Figure 1, reverse osmosis membrane filter element 1 includes intake tunnel 101, water purification path 10 2 and condensed water path 10 3.Need the water carrying out processing to enter in filtering body 10 by intake tunnel 101, after the process of material 11, form water purification part and condensed water part, water purification is flowed out by water purification path 10 2, and condensed water is flowed out by condensed water path 10 3.
Each different reverse osmosis membrane filter element needs the flow proportional determining water purification and condensed water according to actual conditions, to control the water treatment pressure of reverse osmosis membrane, and then forms the water purification of different disposal level.In the present invention, condensed water path 10 3 is provided with the pressurized construction of limited flow, to regulate the flow proportional of water purification and condensed water.This pressurized construction can be controlled, as choke valve, also can determine, such as determine the hole of flow.
In the preferred embodiments of the present invention, pressurized construction is metering orifice 12, and metering orifice 12 regulates condensed water water yield.In the preferred embodiment, condensed water path 10 3 is arranged a baffle plate 120, baffle plate 120 is arranged metering orifice 12, and metering orifice 12 is arranged near the outlet of condensed water passage.In addition, metering orifice 12 can be circular hole, and also can be rectangular gap, as long as can meet flow and pressure requirements, concrete shape be determined according to actual needs.
In the preferred embodiments of the present invention, water purification path 10 2 is provided with an elastomer block 13, this elastomer block 13 can play the effect of check valve.When in water purification path 10 2, water purification flows out, elastomer block 13 becomes to water purification path 10 2 Way out generation bullet under hydrostatic pressure, conducting water purification path 10 2, makes water purification flow out reverse osmosis membrane filter element 1.When reverse osmosis membrane filter element 1 external water stream is for entering filter reverse osmosis membrane filter element 1 inside along water purification path 10 2, elastomer block 13 closes water purification path 10 2 under outside water flow pressure, prevents external water stream from entering reverse osmosis membrane filter element 1.
Can realize the unidirectional control of water purification path 10 2 in this preferred embodiment by means of only an elastomer block 13, and need not arrange check valve, structure is simple, reliable in action.The setting of this elastomer block 13 can be arranged according to actual needs.
