The usefulness of the utility model is only independently controlled parameter by two and is controlled: shearing and pressure.Shearing is to produce through vibrations NF membrane group 32, can use the amplitude of vibration adjusting on control panel to pull, and regulates the amplitude of vibrations, controls the size of vibration amplitude through the speed of motor 33 rotations.Pressure is the power from feed pump.Independently control parameter although shearing and pressure are two, make system performance its powerful performance and normal running, both are indispensable.Will be easily and operate native system reliably, it is to keep it in mind that an emphasis is arranged, and when shaking exactly pressure must be arranged simultaneously, and must shake simultaneously when pressure is arranged.When these vibrations film nanofiltration device (NF) 30 vibrations; NF membrane group 32 diaphragm 308 inside needs certain pressure in vibrations, also can keep the origin-location; Do not have pressure if having only vibrations, may cause diaphragm 308 breakages like this, lost the effect of filtering.On the contrary, moving if system has only feed liquor not arrhea under the situation that does not have vibrations, keep one period very short time only; Because lacked the words of vibrations; When feedstock solution was flowed through diaphragm 308 surface, the material of failing to pass diaphragm 308 can stop and be accumulated on the surface of diaphragm 308, micropore on the diaphragm 308 is caused silt up; The speed that these barriers form is very fast, can make diaphragm 308 lose its usefulness between very short.Thus, the system is note the following: When the system operating pressure of less than 30psi, the system prohibits vibration; vibration amplitude when the system is less than 1/4 inch, the pressure in the environment must not operate longer than 20 seconds; when the first operating system, when it comes to water for the first test, the cleaning, the use of water in the case of very low pressure cleaning systems, and components within the system should be cleaned every one.

In addition, this filtration fluid cylinder 40 is used to collect the soup of depositing after the decolouring, reaches the soup purpose of decolouring.

The course of work that present embodiment is detailed is following:

At first, with in the pending soup input charging fluid cylinder 10.

Next, the feed pump 20 to feed the liquid cylinder 10 in the liquid pumped into vibration membrane nanofiltration unit (NF) 30, the liquid is divided into two liquid from the first input port 301 and the second input port 302 liquid input to the nanofiltration group of 32, while the rotation of the motor 33 and drive connected by a belt 38 soft rotating eccentric block 35, block 35 of the eccentric rotation at high speed centrifugal force generated can cause vibration film nanofiltration device (NF) 30 an upper swing, swinging generated energy to the center drive rod 34, to promote the transmission rod 34 in the center of the group 32 nanofiltration frequency vibration, vibration of the diaphragm 308 via a shearing force to spread sinusoidal surface, although feed pressure via a liquid feed pump constantly pumped into the nanofiltration group 32 are generated, but the shear strength of the diaphragm 308 to the surface while the solids remain in the output from the concentrated liquid discharge port 305, does not precipitate in on the surface of the diaphragm 308, so that the high pressure system base on environment, the continuous and effective separation of the filtered solution and concentrate.The concentrate trunnion of concentrate through NF membrane group 32 belows outwards discharges output and is back in the charging fluid cylinder 10; So that to the concentrate processing of repeatedly decolouring; Simultaneously, filtered fluid extrudes from water producing pipe 323, and this filtered fluid is input to filter in the fluid cylinder 40 and keeps in.

And soup flows at the upper surface of the diaphragm 308 of each standard film part, and filtered fluid sees through diaphragm 308 and flows in the groove 3011 of pallet 307 upper surfaces, and flows in the water producing pipe 323, to obtain filtered fluid through groove 304; And under the soup of the diaphragm 308 upper surfaces through hole through aforementioned correspondence flows into, filter on the diaphragm 308 of the standard film part of one deck; Thus; Flowing of concentrate just had certain direction, and whole NF membrane group 32 is according to aforementioned sequential cascade, and concentrate just is flowing of " S " type; Increased the effective filtration area of unit space upper diaphragm, to enlarge disposal ability more simply.And, contacting with diaphragm 308 at whole flow process herb liquid always, filtered fluid is flowed out by train wheel bridge 321 from the water producing pipe 323 in the middle of the diaphragm 308, and concentrate is separated, from concentrate delivery outlet 305 outputs of NF membrane group 32 sides; Because whole NF membrane group 32 compact conformations, the pressure loss is little, and filtered fluid and concentrate need not to pressurize again and can discharge, for energy consumption has been saved in the separation of soup greatly.

The design focal point of the utility model is: at first; Rotate the centrifugal force that produces and to cause and wave through utilizing motor and belt to drive eccentric block on the drive link of center; The energy that waves generation impels the vibrations of NF membrane group through the center drive link; When the turn up of motor extremely shook the required frequency of environment altogether, the amplitude of NF membrane group vibrations reached to maximum, and the shearing force that high-frequency vibration produced is propagated with sinusoidal manner via the membrane surface in the NF membrane group; Thereby effectively solve the problem of silting up of NF membrane group interior diaphragm, opposing film pollution capacity is stronger; And; Cooperate and to utilize feed pump, charging fluid cylinder and filter fluid cylinder and form piece-rate system, with continuous and effective isolate filtered fluid and concentrate, realized simply and effectively the soup processing of decolouring; Increase operation rate; Can save a large amount of energy, and operation is extremely convenient, is bringing convenience property of user.Secondly; Through utilizing the superimposed filter membrane unit that forms together of the first standard film part, the second standard film part, the 3rd standard film part and the 4th standard film part; And cooperation utilizes the first standard film part and the 3rd standard film part to be monotrysian type standard film part for ditrysian type standard film part, this second standard film part and the 4th standard film part; Make concentrate S-type mobile in the film group, thereby increased the effective filtration area of unit space upper diaphragm, can enlarge soup decolouring disposal ability more simply.Moreover; Through be provided with stoste input port and filtered fluid delivery outlet in train wheel bridge; Form the design of water inlet, upper water-out with this, the bubble that the design of upper water-out makes vibrations film nanofiltration device in separation process, produce is in time got rid of favourable protection diaphragm.In addition, through drive link is provided with two eccentric blocks in the center, but be arranged on the drive link of center with utilizing this two eccentric blocks up-down adjustment and rotatable adjusting; But make two its overlapping areas of eccentric block flexible; To reach the purpose of best vibration amplitude, whole eccentric block is the semi-disc shape, and is provided with arc notch and arc convex in eccentric block; The eccentric force that can strengthen when rotating at a high speed reduces noise, keeps the stability of single rotating manner.At last, through being wrapped in the upper casing the NF membrane group is sealed, motor is installed in the base; And cooperate to utilize between upper casing and the base and be provided with spring, make soup handle in the casing of sealing on the one hand and carry out, protected operating personnel's safety effectively; On the other hand, motor and NF membrane group are independently installed, and noise is low; Good damping effect is moved more stable.

The above; It only is the preferred embodiment of the utility model; Be not that the technical scope of the utility model is done any restriction; So every technical spirit according to the utility model all still belongs in the scope of the utility model technical scheme any trickle modification, equivalent variations and modification that above embodiment did.
