Brief description of the drawings
Fig. 1 show the structural representation of power-free back washing super-filter purifying device in the present invention.
Specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described, and example is served only for explaining the present invention, is not intended to limit Determine the scope of the present invention.
As shown in figure 1, be a kind of structural representation of power-free back washing super-filter purifying device 100 in the present invention, including Water inlet system 10, filtration system 20 and water storage system 30.The bulk shape structure of the power-free back washing super-filter purifying device 100 Square or round can be made, the water inlet system 10, the water storage system 20 and the filtration system 30 are from top to bottom Set gradually.
The water inlet system 10 includes water inlet 11, reaction tank 12, folded plate 13, the valve 15 of water inlet pipe 14 and first.It is described Water inlet 11 is arranged at the side of the reaction tank 12, used as the entrance of raw water.The quantity of the folded plate 13 is more than or equal to two It is individual, multiple folded plates 13 top and bottom for being arranged at the reaction tank 12 successively staggeredly, its effect is mainly to adding The raw water of the medicaments such as flocculant is sufficiently mixed, and more thoroughly particle aggregation powered in raw water is got up, convenient follow-up Filtering is disposed.The water inlet pipe 14 is arranged on opposite side relative with the water inlet 11 on the reaction tank 12, described One valve 15 is arranged on the water inlet pipe 14, and the raw water after the reaction tank 12 is sufficiently mixed can be by the water inlet pipe 14 enter next system.
The filtration system 20 includes Rose Box 21, current divider 22, settling vessel 23, ultrafiltration membrane cavity 24, collecting box 25, draining The valve 27 of pipe 26 and second.The Rose Box 21 is arranged on the lower section of the reaction tank 12.The current divider 22, the settling vessel 23 and the ultrafiltration membrane cavity 24 be arranged in the Rose Box 21 and be sequentially connected, it is described specifically, in order to improve filter efficiency The quantity of settling vessel 23 and the ultrafiltration membrane cavity 24 is more than or equal to two, and both quantity are equal, multiple settling vessels 23 It is uniformly arranged and is connected with the current divider 22 around the current divider 22, multiple ultrafiltration membrane cavities 24 is around the shunting Device 22 is uniformly arranged and is connected with multiple settling vessels 23 respectively.The settling vessel 23 mainly carries out preliminary to raw water The materials such as clarification and precipitation, most of silt, mechanical admixture, colloid in removal raw water, the ultrafiltration membrane cavity 24 is mainly removed Go most of bacterium, virus, microorganism in water so that water quality reaches and is fully cleaned up.The collecting box 25 and the precipitation Device 23 is connected and is arranged at the lower section of the Rose Box 21, is mainly used in being retained down after collection is filtered via the settling vessel 23 Silt and impurity, in order to guarantee in time to exclude the impurity in the collecting box 25 in time, the filtration system 20 is also wrapped The blow-off pipe 28 being connected with the collecting box 25 and the 3rd valve 29 being arranged on the blow-off pipe 28 are included, the described 3rd is opened Valve 29, you can the impurity in the collecting box 25 is discharged via the blow-off pipe 28.The drainpipe 26 and the ultrafiltration The lower end of membrane cavity 24 is connected, and the 3rd valve 29 is arranged on the drainpipe 26, can be by controlling first valve 15 and the switch of second valve 27 the ultrafiltration membrane cavity 24 backwashed.
The water storage system 30 is arranged between the water inlet system 10 and the filtration system 20, including the He of storage tank 31 Delivery port 32.The storage tank 31 is connected with the ultrafiltration membrane cavity 24, and is arranged at the reaction tank 12 and the Rose Box In the middle of 21, for storing the product water after being filtered via the filtration system 20.The delivery port 32 is arranged at the storage tank 31 On, product water can flow out for people to use via the delivery port 32.
In order to be able to the switch switching for automatically controlling first valve 15 and second valve 27 of timing, and control The switch of the 3rd valve 29, the power-free back washing super-filter purifying device 100 also includes control system, the control system The control principle of system is prior art, be will not be repeated here.
Operation principle of the invention is as follows:When being filtered to raw water, first valve 15 is opened, second valve Door 27 is closed, and raw water can enter the filtration system 20 via the reaction tank 12 and the water inlet pipe 14 successively, in the mistake In filter system 20, water can carry out filtration treatment via the isocon, the settling vessel 23 and the ultrafiltration membrane cavity 24 successively, warp The product water crossed after the filtration system 20 is filtered can enter the storage tank 31, and can supply people via the outflow of the delivery port 32 Use;When being backwashed to the ultrafiltration membrane cavity 24, first valve 15 is closed, and second valve 27 is opened, institute The product water in storage tank 31 is stated in the case where additionaling power is not needed, the ultrafiltration membrane cavity can be entered because hydrostatic pressure flows backwards 24, start to backwash the ultrafiltration membrane cavity 24, finally, the product water rinsed after the ultrafiltration membrane cavity 24 is via the draining Pipe 26 is discharged.After the long-play of power-free back washing super-filter purifying device 100, can be overstock in the collecting box 25 More impurity, now need to only open the 3rd valve 29, and impurity is discharged via the blow-off pipe 28.Wherein, described One valve 15, second valve 27 and the 3rd valve 29 can be by the control systems according to program set in advance Control is timed, the switch switching of each valve is completed without staff on duty.
Power-free back washing super-filter purifying device in the present invention, completely solves the device and is moved in system operation The problem in power source, reduces operation and maintenance cost, especially when being backwashed to milipore filter, can directly utilize water storage Impulse force when water purification in case flows downward is rinsed to milipore filter, is backwashed without increasing extra power so that should Device can be suitably used for different water supply environment, and flexibility is strong, meanwhile, can also opening by each valve of control system timing controlled Close, so as to control the automatic switchover filtered and backwash, realize unattended.
The foregoing is only presently preferred embodiments of the present invention, be not intended to limit the invention, it is all it is of the invention spirit and Within principle, any modification, equivalent substitution and improvements made etc. should be included within the scope of the present invention.
