As it is shown in figure 1, ultrafiltration water cleaning systems 1 according to embodiments of the present invention includes ultra-filtration element 100 and air transporting arrangement 210。
There is in ultra-filtration element 100 ultrafiltration membrane filaments 160 and ultra-filtration element 100 is provided with original water inlet 110, pure water outlet 120 and flushing water outlet 130, original water inlet 110 is connected to former water on-off valve 111, pure water outlet 120 is connected to pure water on-off valve 121, and flushing water outlet 130 is connected to flushing water on-off valve 131。Air transporting arrangement 210 is connected for carrying gas, air transporting arrangement 210 to export 120 with pure water to ultra-filtration element 100。
Ultrafiltration water cleaning systems 1 according to embodiments of the present invention, by arranging the ultra-filtration element 100 with ultrafiltration membrane filaments 160, it is possible to when making the water at water source place pass through ultra-filtration element 100, utilizes ultrafiltration membrane filaments 160 that water is filtered, to realize water purification。
And, ultrafiltration water cleaning systems 1 has the ultra-filtration element 100 of original water inlet 110, pure water outlet 120 and flushing water outlet 130 by arranging, and on original water inlet 110, connect former water on-off valve 111, export at pure water and on 120, connect pure water on-off valve 121, export at flushing water and on 130, connect flushing water on-off valve 131。So can pass through to change the on off operating mode of pure water on-off valve 121, former water on-off valve 111 and flushing water on-off valve 131, ultrafiltration water cleaning systems 1 is made to be switched to the state that ultra-filtration element 100 is washed away from the state preparing pure water, make ultrafiltration water cleaning systems 1 can not only prepare pure water, and ultra-filtration element 100 can be washed away so that impurity is not easily accumulated on ultrafiltration membrane filaments 160。
In addition, by arranging air transporting arrangement 210, air transporting arrangement 210 can be utilized to carry gas to ultra-filtration element 100, ultrafiltration membrane filaments 160 can expand along with transfer of gas, reduce impurity adhesive force on ultrafiltration membrane filaments 160 surface, make the impurity being attached on ultrafiltration membrane filaments 160 surface be more prone to come off under the deformation effect of ultrafiltration membrane filaments 160。So when ultra-filtration element 100 is washed away, can more easily wash away by impurity and discharge with current, to improve the scouring effect to ultra-filtration element 100, it is to avoid impurities accumulation too much causes the flow reduction of ultra-filtration element 100 or breakage occurs, and extends the service life of ultra-filtration element 100。
Therefore, ultrafiltration water cleaning systems 1 according to embodiments of the present invention has the advantages such as good, the long service life of scouring effect。
Below with reference to the accompanying drawings ultrafiltration water cleaning systems 1 according to the specific embodiment of the invention is described。
In some specific embodiments of the present invention, as it is shown in figure 1, ultrafiltration water cleaning systems 1 according to embodiments of the present invention includes ultra-filtration element 100 and air transporting arrangement 210。
Ultrafiltration water cleaning systems 1 also includes the pressure-detecting device 220 exporting 120 place's pressure for obtaining pure water, and whether pressure-detecting device 220 exports the 120 pressure detecting ultrafiltration membrane filaments 160 being connected to export 120 places according to pure water with pure water damaged。So can while inflating to ultra-filtration element 100, whether utilizing pressure-detecting device 220 to detect pure water, to export the pressure at 120 places damaged to detect ultrafiltration membrane filaments 160。Compare the ultrafiltration water purifier in correlation technique, after there is breakage in ultrafiltration membrane filaments 160, whether due to user, cannot to observe directly ultrafiltration membrane filaments 160 damaged, whether the clean water area using different water that also cannot pass through to prepare is fully cleaned up, it is difficult to learn that ultrafiltration membrane filaments 160 is damaged, and water cannot be fully cleaned up by the ultrafiltration membrane filaments 160 of breakage, partial impurities can be passed through the damaged part of ultrafiltration membrane filaments 160 and export 120 discharges from pure water, affect the use water quality of user, even endanger the healthy of user。Whether ultrafiltration water cleaning systems 1 then can detect ultrafiltration membrane filaments 160 damaged, allows users in time ultra-filtration element 100 is replaced when breakage occurs ultrafiltration membrane filaments 160, thus ensureing the purifying water effect of ultrafiltration water cleaning systems 1。
Specifically, as it is shown in figure 1, ultrafiltration membrane filaments 160 limits former pool 140 and pure water district 150 in ultra-filtration element 100, flushing water outlet 130 connects with former pool 140, and original water inlet 110 connects water source and former pool 140, and pure water outlet 120 connects with pure water district 150。Need exist for being understood by, " connect with former pool 140 " and " connecting with pure water district 150 " refers to that directly connection is filtered without ultrafiltration membrane filaments 160, pure water can be passed through between pure water district 150 and former pool 140, ultrafiltration membrane filaments 160 shown in Fig. 1, only for the purposes of describing, is not intended to limit the shape of ultrafiltration membrane filaments 160。
Owing to when rinsing, air transporting arrangement 210 carries gases to exporting 120 sides directly connect in ultra-filtration element 100 with pure water, it is possible to use pressure-detecting device 220 obtains pure water and exports the pressure at 120 places and whether pressure detecting ultrafiltration membrane filaments 160 according to pure water outlet 120 is damaged。Due to the surface tension effects of water, if breakage does not occur ultrafiltration membrane filaments 160, gas will not enter the opposite side of ultrafiltration membrane filaments 160 from the side of ultrafiltration membrane filaments 160 by ultrafiltration membrane filaments 160。So when carrying gas to the side of ultrafiltration membrane filaments 160, if pressure can reach predetermined value, can determine whether that breakage does not occur ultrafiltration membrane filaments 160, if there is breakage in ultrafiltration membrane filaments 160, gas can pass through damaged part through ultrafiltration membrane filaments 160, causes that the pressure that pure water exports 120 places is unable to reach predetermined value。Thus can so that whether breakage detects to ultrafiltration membrane filaments 160, in order to allow users to change in time damaged ultra-filtration element 100, thus ensureing user's water quality。
In other words, due to rinse time air transporting arrangement 210 carry gas to pure water district 150, it is possible to use pressure-detecting device 220 obtain pure water export 120 places pressure and according to pure water export 120 pressure detecting ultrafiltration membrane filaments 160 whether damaged。Due to the tension force of water, when breakage does not occur ultrafiltration membrane filaments 160, gas will not enter former pool 140 from pure water district 150。So when carrying gas to pure water district 150, if the pressure of pure water outlet 120 can reach predetermined value, can determine whether that breakage does not occur ultrafiltration membrane filaments 160, if there is breakage in ultrafiltration membrane filaments 160, gas can pass damaged part and enter former pool 140, causes that pure water exports 120 place's pressure and do not reach predetermined value。
Specifically, air transporting arrangement 210 can be air pump, and connects pure water district 150 and extraneous air, and pressure-detecting device 220 can be pressure switch。So can so that the acquisition of source of the gas。
It will be appreciated by those skilled in the art that ultra-filtration element 100 can also connect to realize gas conveying with compressed gas source, and between ultra-filtration element 100 and compressed gas source, is connected on-off valve control gas can enter。

Specifically, conveying gas and pressure release process can repeatedly, be easy to further improve scouring effect。
Fig. 1 illustrates the ultrafiltration water cleaning systems 1 according to one concrete example of the present invention。As it is shown in figure 1, ultrafiltration water cleaning systems 1 also includes controller 300。Controller 300 respectively with former water on-off valve 111, flushing water on-off valve 131, air transporting arrangement 210, pressure-detecting device 220 and relief valve 230 communication。So can facilitate the use controller 300 and control the on off operating mode of former water on-off valve 111, flushing water on-off valve 131, air transporting arrangement 210, pressure-detecting device 220 and relief valve 230, so that ultrafiltration water cleaning systems 1 whether detect ultrafiltration membrane filaments 160 damaged, and can so that ultrafiltration water cleaning systems 1 switches between controlling the water circulation state and scouring state。
Specifically, when carrying gas in ultra-filtration element 100, controller 300 can record the time of conveying gas, when carrying gas to exceed certain time in ultra-filtration element 100 and pure water exports when the pressure at 120 places fails to reach predetermined value and judges that breakage occurs ultrafiltration membrane filaments 160。
Advantageously, ultrafiltration water cleaning systems 1 also includes prompting apparatus (not shown)。Whether described prompting apparatus is used for pointing out ultrafiltration membrane filaments 160 damaged, described prompting apparatus and controller 300 communication。So can utilize described prompting apparatus prompting user's ultrafiltration membrane filaments 160 that breakage occurs, consequently facilitating ultra-filtration element 100 is replaced by user in time。
Alternatively, as it is shown in figure 1, air transporting arrangement 210, pressure-detecting device 220 and relief valve 230 are connected in parallel。So can so that the connection of air transporting arrangement 210, pressure-detecting device 220 and relief valve 230。
Specifically, former water on-off valve 111 and flushing water on-off valve 131 are electrical ball valve, and pure water on-off valve 121 is faucet, and relief valve 230 is electromagnetic valve。So it is possible not only to be easy to user and takes pure water, and controller 300 can be facilitated the use and open or close former water on-off valve 111, flushing water on-off valve 131 and relief valve 230, so that whether detection ultrafiltration membrane filaments 160 is damaged, it is simple to ultrafiltration water cleaning systems 1 is switching between the state of flushing and controlling the water circulation state。
More specifically, as it is shown in figure 1, pure water on-off valve 121 and air transporting arrangement 210 are connected in parallel。So can so that the connection of pure water on-off valve 121 and air transporting arrangement 210。
Specifically, as it is shown in figure 1, pure water on-off valve 121 can all connect with pure water outlet 120 with air transporting arrangement 210。So can reduce the open amount on ultra-filtration element 100, be possible not only to be easy to the manufacture of ultra-filtration element 100, and can so that ensureing the sealing of ultra-filtration element 100。
The work process of the ultrafiltration water cleaning systems 1 according to one specific embodiment of the present invention is described below with reference to Fig. 1。
During ultrafiltration water cleaning systems 1 normal controlling the water circulation, air transporting arrangement 210 is in halted state, and former water on-off valve 111 is opened, and flushing water on-off valve 131 is closed, and relief valve 230 cuts out。User opens pure water on-off valve 121, and the aquiform stool at water source place enters the former pool 140 of ultra-filtration element 100 through original water inlet 110, enters pure water district 150 by ultrafiltration membrane filaments 160 after being filtered, and exports 120 discharges finally by pure water。
When ultrafiltration membrane filaments 160 is rinsed by ultrafiltration water cleaning systems 1, pure water on-off valve 121 is closed, and former water on-off valve 111 is closed, and flushing water on-off valve 131 is opened, and relief valve 230 cuts out。Air transporting arrangement 210 works, and is entered by air pump in the pure water district 150 of ultra-filtration element 100, makes ultrafiltration membrane filaments 160 deform upon, and promotes the impurity being attached on ultrafiltration membrane filaments 160 to come off。
Surface tension effects due to water, when there is not breakage in ultrafiltration membrane filaments 160, gas will not pass through ultrafiltration membrane filaments 160 and enter former pool 140 from pure water district 150, air pressure in pure water district 150 raises with gas input, and in ultra-filtration element 100, the water in former pool 140 will export 130 discharges from flushing water。Pressure-detecting device 220 detects the pressure in pure water district 150, if in ultra-filtration element 100 pure water district 150 rise to predetermined value (0.1MPa) atmospherically, illustrate that breakage does not occur ultrafiltration membrane filaments 160。After pure water district 150 internal gas pressure reaches predetermined value, air transporting arrangement 210 quits work, and flushing water on-off valve 131 is closed subsequently, and former water on-off valve 111 and relief valve 230 will be opened。Due to the effect of water source place pressure, the water at water source place will be filtered through pure water outlet 120 by ultrafiltration membrane filaments 160 and discharge from relief valve 230。After certain time (1 minute), the air of ultra-filtration element 100 is completely exhausted out, and relief valve 230 cuts out by controller 300, and informs that user's filter element is intact, and detection completes。
