Embodiment:
As shown in Figure 1, household purified water treatment device of the present invention mainly comprises melt-blown core lauter tub 3, check valve 4, hollow fiber film assembly 5, pressure transmitter 8 and diaphragm type air pressure tank 9.Hollow fiber film assembly 5 can adopt the small-sized hyperfiltration membrane assembly of LH3-8Ad type of Hainan liter Pure Water Scientific And Technical Industry Co., Ltd, the water side of melt-blown core lauter tub 3 by communicating pipe the feed-water end with hollow fiber film assembly 5 be communicated with, check valve 4 was installed on this communicating pipe, the water side of hollow fiber film assembly 5 (being treated water outlet 16 places) is connected with and purifies water pipe 11, and the water outlet place that purifies water pipe 11 is equipped with tap water tap 7.Purify on the water pipe 11, pressure transmitter 8 and diaphragm type air pressure tank 9 also are installed between treated water outlet 16 and tap water tap 7.Diaphragm type air pressure tank 9 can select for use the Shenzhen to close the Bertoni stainless steel air pressure jar of sharp Science and Technology Ltd. deeply, and useful volume is according to the domestic water consumption reasonable selection.As preferred implementation of the present invention, treated water outlet 16 places that pressure transmitter 8 is installed in hollow fiber film assembly 5 can have higher accuracy.
Melt-blown core lauter tub 3 of the present invention can constitute by a melt-blown filter is installed in a cylindrical outer casing.Wherein, it is the melt-blown filter of PP cotton that filter core can adopt the clean forever material that reaches the production of purification scientific ﹠ technical corporation in Hangzhou, and cylindrical outer casing can revolve and open, so that regularly carry out the replacing of melt-blown filter.
In embodiment shown in Figure 1, apparatus of the present invention also are equipped with lift pump 1, and according to the difference of each tame rainwater water cellar, lift pump 1 can be selected the magnetic drive pump or Jishui, the Shanghai group company solar DC pump of prosperous dynamo-electric company limited of Leqing market day for use.Lift pump 1 is communicated with melt-blown core lauter tub 3 by water inlet pipe 2, and lift pump 1 is connected with pressure transmitter 8.Further, apparatus of the present invention can be installed a controller 10 as shown in Figure 1, and lift pump 1 is connected with pressure transmitter 8 by controller 10, and promptly controller 10 is electrically connected with lift pump 1, and controller 10 is connected by lead 12 with pressure transmitter 8.Pressure transmitter 8 makes apparatus of the present invention keep required force value, the promptly energy-conservation normal water supply of realizing again according to the work of pressure change by controller 10 control lift pumps 1.The user can also connect solar panel with controller 10 according to actual needs, by the operation of Driven by Solar Energy lift pump 1, lowers working cost.Controller 10 can adopt the controller in the JSS1.38-45-36/210 solar DC pump of Jishui, Shanghai group company.
As shown in Figure 1 to Figure 3, except treated water outlet 16, hollow fiber film assembly 5 also is provided with back flushing water outlet 15, and back flushing water outlet 15 is connected with uses mixedly water pipe 17, and by the 6 control drainings of miscellaneous water tap.
During works better, when apparatus of the present invention pressure reduced, pressure transmitter 8 was opened by controller 10 control lift pumps 1, and lift pump 1 pumps into apparatus of the present invention with accumulative rainwater in the water cellar, behind the primary filter through melt-blown filter bucket 3, enter hollow fiber film assembly 5.As shown in Figure 2, hollow fiber film assembly 5 adopts the inner pressed structures, and after water entered hollow-fibre membrane film silk 13 in the hollow fiber film assembly 5, under the effect of pressure, water saw through film, and suspended impurity then is trapped within the inside of hollow-fibre membrane film silk 13.Collect back treated water outlet 16 through the water behind the hollow-fibre membrane film silk 13 by the perforation collection tube in the hollow fiber film assembly 5 14 and enter diaphragm type air pressure tank 9 by hollow fiber film assembly 5.Diaphragm type air pressure tank 9 is mainly used in storage and presses and water storage, regulates the pressure of buffering apparatus of the present invention, avoids because the keying of head dragon causes the frequent unlatching of lift pump 1; For the ultra-filtration membrane back flushing provides the pressure and the water yield, realized no pump back flushing simultaneously.After diaphragm type air pressure tank 9 pressure reached certain value, controller 10 control lift pumps 1 cut out, after tap water tap 7 waters, pressure is reduced to Schwellenwert, under the effect of pressure transmitter 8 and controller 10, lift pump 1 is opened once again, enters the next round work period.
As shown in Figure 3, after miscellaneous water tap 6 was opened, the dense water of hollow-fibre membrane film silk 13 inside was directly discharged by the back flushing water outlet 15 of hollow fiber film assembly 5, realizes the positive developing result of hollow-fibre membrane; Simultaneously, the water purification in hollow-fibre membrane film silk 13 outsides instead sees through the film surface under the pressure effect of diaphragm type air pressure tank 9, realize the backwash effect of hollow-fibre membrane film silk 13.Positive and negative flushing water outlet is discharged by miscellaneous water tap 6 by using mixedly water pipe 17 through the back flushing water outlet 15 of hollow fiber film assembly 5, as the daily water of using mixedly, has utilized limited Freshwater resources fully.
To sum up, former water enters melt-blown core lauter tub 3 by lift pump 1 and carries out the one-level processing, remove the suspended substance and the impurity of larger particles in the water, enter hollow fiber film assembly 5 through the former water after the one-level processing and carry out second-stage treatment, further remove fine suspension and larger molecular organics in the water, make delivery turbidity reach 0.1NTU, reach national drinking water standard (GB5749-2006).Purifying waste water after the second-stage treatment by 7 water outlets of tap water tap.Add at lift pump 1 and to depress, apparatus of the present invention are carried out the water storage storage by the effect of diaphragm type air pressure tank 9 and are pressed when satisfying water outlet, when capping value that device pressure rises, send the termination of pumping signal by pressure transmitter 8, and lift pump 1 cuts out.7 places fetch water in a large number when the tap water tap, and after device pressure dropped to certain value gradually, pressure transmitter 8 sent the turn on pump signal, and lift pump 1 is opened.The present invention realizes the keying of lift pump, energy-saving and water-saving, the secondary pollution of having avoided water tank to cause automatically by adopting this pressure sensing control mode.After miscellaneous water tap 6 was opened, the water after one-level is handled directly flowed in hollow-fibre membrane under pressure fast, by 6 water outlets of miscellaneous water tap, realized the positive washing action of ultra-filtration membrane; Purify waste water then under 9 effects of diaphragm type air pressure tank, instead see through ultra-filtration membrane, discharge, in this process, realized back flushing ultra-filtration membrane by miscellaneous water tap 6.The back flushing water outlet has made full use of Freshwater resources as miscellaneous water.
