Description
The utility model relates to a kind of accumulating mechanism that the hollow fiber ultrafiltration membrane water purifier is carried out back flushing.
At present, hollow fiber ultrafiltration membrane more and more is subjected to people's welcome with safe and reliable and characteristics long service life, is widely used in the fluid purification field.With the pump is power, is washed by reverse with the clean liquid centering hollow fiber ultra-filtration membrane after purifying, and rinses out with the various impurity that are deposited on the film surface stagnating on the micropore, and with the liquid in the chamber to be filtered, discharges purification system by discharge orifice.Here it is for prolonging unique effective way-backwashing technology of hollow fiber ultrafiltration membrane work-ing life and raising effect.Present small-sized cleaner can not be provided with backwashing pump owing to be subjected to the restriction of working conditions, and therefore, the long-lived characteristics of hollow fiber ultrafiltration membrane also are difficult to reveal in bantam.
The purpose of this utility model is exactly at the problems referred to above, and a kind of work system-expanding energy storage of splashing that can carry out back flushing under no pump state to hollow fiber ultrafiltration membrane is provided.
The utility model design principle and each key element are as follows:
1, air chamber: select moulding for use, bloated sebific duct is formed an airtight cavity with splashing.Intracavity gas pressure is about 0.1MPa.
According to Boyle-Marriot law; When temperature-resistant, the gas pressure intensity of certain mass and its volume are inversely proportional to.When the sebific duct expansion, gas chamber volume diminishes, and gas increases by force the sebific duct wall pressure in the air chamber.With sebific duct, expand stopper and the air chamber of splashing be provided with by a certain percentage, can guarantee that the sebific duct of splashing after expanding has enough pressure to intraluminal clean water.
2, sebific duct: select for use the natural preferably or synthetic rubber of elastic deformation to make.
Tap water pipe line pressure generally about 0.4MPa, when clean water flowed into the sebific duct of end sealing under this pressure action, splashed bloated under differential pressure action, and the sebific duct internal volume is constantly increased by sebific duct, and the clean water that injects sebific duct increases gradually.The pressure that produces when sebific duct wall screen resilience adds when gas pressure intensity equals pipe network water pressure in the upper gas chamber, and sebific duct stops to splash bloated, injects water and is stationary state.Open when discharge orifice, when injecting the wall pressure reduction, the clean water in the sebific duct carries out counterflush with certain pressure to hollow fiber ultrafiltration membrane under the strong acting in conjunction of the gentle constant pressure of sebific duct screen resilience.
3, the bloated stopper of splashing: select for use frivolous knitted fabrics or thin chamber to mould materials and parts and all can.
Because hose material has the certain physical mechanical property, be subjected to tensile strength at yield, unit elongation, rebound resilience, anti tear, stretch deformation and restriction such as ageing-resistant surely; Also have process technology limit such as density, uniformity coefficient in the making processes not shortcoming, therefore cause the aging and deformation of local fatigue at work easily, therefore must make sebific duct splash in expanding stressed evenly, deformation is reasonable, the employing stopper structure that expands of splashing can limit sebific duct deformation process and size, avoids local strength not enough, aging that limit causes crossed in deformation, keeps the sebific duct long term operation stable.
4, use for adapting to the low user of ductwork pressure, valve is set on the air chamber wall.When ductwork pressure was low, sebific duct was splashed and can not expanded or not in place, water shortage when causing back flushing.Unclamp sealing bolt, make air chamber pressure maintain 0.1MPa (standard atmospheric pressure) all the time, sebific duct is splashed and is expanded to design attitude, and the clean water that q.s arranged uses during for back flushing.
The utility model major advantage:
1, do not need power supply and pump to realize hollow fiber ultrafiltration membrane is carried out back flushing, prolong the work-ing life of hollow fiber ultrafiltration membrane.
2, volume is little, simple in structure, is easy to make.
Figure one is a structural representation of the present utility model;
Figure two is the utility model embodiment one; Owing to limited by environment for use, also the energy storage delivery outlet can be sealed.By with cleaner and be unified into state shown in the figure two.Except that the clean water outflow was directly flowed out by the cleaner water outlet, its program principle and figure were together.
Figure three is the utility model embodiment two; Because hollow fiber ultrafiltration membrane is carried out two requirements of having purified waste water of back flushing, and the first has certain pressure, it two is that enough water storages are arranged, so the retaining sebific duct must have certain length.For adapting to various environment needs, be suitably to shorten air chamber length, effective equally when the parallel connection of energy-storage type back flushing device is designed to state shown in the figure three in the utility model.
Below in conjunction with accompanying drawing concrete structure of the present utility model is described in further detail:
The utility model comprises being equipped with in prosopyle 1, chamber to be filtered 2, the chamber to be filtered 2 has weep hole 4, tubular fibre cleaner 3 to link to each other with sebific duct 5 on hollow fiber ultrafiltration membrane cleaner 3, chamber to be filtered 2 sidewalls, the other end of sebific duct 5 is a water purification taphole 6, the sebific duct 5 outer suits stopper 7 and form on energy-storage type back flushing devices 12, the gas chamber shell 8 with gas chamber shell 8 valve 9 is arranged of expanding of splashing, valve 9 places have the sealing bolt 11 of 0 RunddichtringO 10 by dress.
Work of the present utility model is achieved in that when water purification taphole 6 and opens that tap water by prosopyle 1, chamber to be filtered 2, is filtered into clean water through tubular fibre cleaner 3 under the hydraulic pressure effect.
Clean water flows out through sebific duct 5, water purification taphole 6, and various impurity are cleaned and are suspended in the chamber 2 to be filtered or on the hollow-fibre membrane outer wall attached to cleaner 3 after device 3 filters.
When water purification taphole 6 is closed, tap water enters sebific duct 5 by prosopyle 1, chamber to be filtered 2, cleaner 3 under the hydraulic pressure effect, and sebific duct 5 is in the effect of inside and outside differential pressure, it is bloated that sebific duct 5 is constantly splashed, when coincideing with the bloated stopper 7 of splashing, end sebific duct 5 outer walls, pressure equilibrium in the system, and water is no longer mobile.
Open when weep hole 4, chamber to be filtered 2 internal pressures reduce; Splash and expand clean water in the sebific duct 5 under air chamber pressure and the effect of sebific duct screen resilience, wash, make attached to hollow-fibre membrane outer wall and the various impurity that are suspended in the chamber 2 to be filtered and discharge purification systems through weep hole 4 by reverse hollow-fibre membrane to cleaner 3.
