The working process that present embodiment is detailed is following:

(1) the cold-rolling emulsion waste water that iron and steel cold-rolling equipment 10 is produced inputs in the collecting tank 20 keeps in.

(2) the use of the feed pump 20 is collected in the cold pool emulsion into a waste water pump vibration membrane ultrafiltration device (UF) 30, the waste water is divided into two liquid from the first input port 301 and the second input port 302 liquid input to the film set of 32, while the rotation of the motor 33 and drive belt 38 through the flexible connection of the rotating eccentric block 35, the eccentric block 35 rotates at high speed centrifugal force generated can cause shock membrane ultrafiltration device (UF) 30 upper swing , rocking generated energy to the center drive rod 34, to promote the transmission rod 34 in the center of the film on the group of 32 high-frequency vibration, the vibration generated by the shearing force to a sinusoidal surface of the diaphragm 308 to spread, although feed pressure via feed pump continuously pumps the waste into the membrane module 32 to produce, but the shearing force of the diaphragm 308 to the surface while the solids remain in the output from the thick oil discharge port 305 is not deposited on the surface of the diaphragm 308, so that the high pressure in the system base on environment, the continuous and effective separation of the serum of 90% and 10% of the concentration of oil.10% dense oil outwards discharges output through the dense oily trunnion of film group 32 belows, and simultaneously, 90% clear liquid extrudes from water producing pipe 323, keeps in the pond 40 in the middle of this clear liquid of 90% is input to.

And waste water flows at the upper surface of the diaphragm 308 of each standard film part, and clear liquid 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 clear liquid through groove 304; And under the waste water 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 dense oil just had certain direction, and whole film group 32 is according to aforementioned sequential cascade, and dense oil just is flowing of " S " type; Increased the effective filtration area of unit space upper diaphragm, to enlarge processing power more simply.And waste water contacts with diaphragm 308 always in whole flow process, and clear liquid is flowed out by train wheel bridge 321 from diaphragm 308 intermediary water producing pipes 323, and dense oil is separated to come, and discharges from the dense oil outlet 305 of film group 32 sides; Because whole film group 32 compact constructions, the pressure-losses is little, and clear liquid and dense oil need not to pressurize again and can discharge, for energy consumption has been saved in the separation of waste water greatly.

(3) in middle pond 40, replenish the adding emulsifier, utilize emulsifier that clear liquid is carried out further allocation processing and form cold-rolling emulsion, these cold-rolling emulsions are imported into and carry out reuse in the iron and steel cold-rolling equipment 10.

The design focal point of the utility model is: at first, utilize the cf-of the eccentric block rotation generation on motor and the belt drive center transmission rod to cause through cooperation and wave, the energy that waves generation impels the vibrations of film group through the center transmission rod; When the turn up of motor extremely shakes the required frequency of environment altogether; The amplitude of film group vibrations reaches to maximum, and the shearing force that high-frequency vibration produced is propagated with sinusoidal manner via the membrane surface in the film group, thereby effectively solves the problem of silting up of film group interior diaphragm; Opposing film pollution capacity is stronger; Realized simply and effectively cold-rolling emulsion waste water being recycled processing, better processing effect, processing cost are also lower; And; Cooperate and utilize iron and steel cold-rolling equipment, collecting tank and middle pond composition cold-rolling emulsion waste water reclamation to utilize system; With continuous and effective isolate clear liquid and dense oil, but clear liquid be transfused in the middle of pond and obtained the cold-rolling emulsion of reuse through replenish adding emulsifier, in these cold-rolling emulsion reuse to iron and steel cold-rolling equipments; And whole wastewater treatment process need not add chemical, has guaranteed the reuse quality of emulsion.Secondly; Through utilizing the superimposed filtering 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 dense oil S-type mobile in the film group, thereby increased the effective filtration area of unit space upper diaphragm, can enlarge the processing power of cold-rolling emulsion waste water more simply.Moreover, through be provided with former water input and clear liquid delivery port in train wheel bridge, forming the design of water inlet, upper water-out with this, the bubble that the design of upper water-out makes vibrations membrane ultrafiltration device in sepn process, produce is in time got rid of favourable protection diaphragm.At last, through transmission rod is provided with two eccentric blocks in the center, but be arranged on the transmission rod 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; Eccentric force in the time of can strengthening high speed rotating reduces noise, keeps the stability of single rotating manner.

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.
