Referring to fig. 1, the utility model discloses a buffer tank 7, group pump 8, ultrafiltration column 9, ultrafiltration column (9) is provided with ultrafiltration column inlet 11, ultrafiltration column return current mouth 12, filtration export 13, and ultrafiltration column 9 feed liquor pipeline end is provided with valve one 1, and ultrafiltration column return current mouth 12 department is provided with valve two 2, and buffer tank 7 return current pipeline inlet is provided with valve three 3, is provided with the drain line on the pipeline between buffer tank 7 and group pump 8, be provided with valve four 4 on the drain line, is provided with back flush return circuit 16 between group pump 8 liquid outlet and ultrafiltration column inlet 11, is connected to ultrafiltration column return current mouth 12, and back flush return circuit 16 is provided with valve five 5 and back flush manometer 17, and ultrafiltration column inlet 11 department is provided with valve six 6 and filtration manometer 10; the buffer tank 7 is provided with an independent water inlet 15 and an independent liquid inlet 14.

When the ultrafiltration machine is used for carrying out ultrafiltration on the liquid medicine, the working process is as shown in figure 2, the first valve 1 and the fourth valve 4 are closed, the second valve 2 and the third valve 3 are kept opened, the liquid medicine enters from the liquid inlet 14 of the buffer tank 7 and flows into the group pump 8 through the buffer tank 7, enters from an ultrafiltration column liquid inlet 11 at the bottom of an ultrafiltration column 9 under the pressurization of a group pump 8, and a filtering pressure gauge 10 arranged at the ultrafiltration column liquid inlet 11 is used for detecting the pressure of the liquid medicine entering the ultrafiltration column 9, so as to prevent the liquid medicine entering the ultrafiltration column 9 from being damaged due to overlarge pressure, remove useless macromolecular substances in the liquid medicine entering the ultrafiltration column 9 through the filter membrane, discharge the liquid medicine after the filtering process from a filtering outlet 13, the residual liquid medicine which is not subjected to the filtering procedure is discharged from the ultrafiltration column return port 12 and returns to the buffer tank 7 through a pipeline to carry out the filtering process again.

And after the ultrafiltration work of the ultrafiltration machine is finished, the group of pumps 8 is shut down, the first valve 1 and the fourth valve 4 are opened, the liquid medicine in the whole set of filtering system pipeline is completely discharged, and then the ultrafiltration machine is cleaned.

The cleaning method for the ultrafiltration apparatus before the modification is shown in FIG. 2: connect earlier and wash independent water inlet 15 entering buffer tank 7 from buffer tank 7, wash buffer tank 7 through spraying the ball, water after the washing flows out from the outlet behind valve four 4, buffer tank 7 is clean after, close valve one 1, valve four 4, open group pump 8, add the flush fluid from independent water inlet 15 on buffer tank 7, the flush fluid flows into group pump 8 through buffer tank 7, through filtering manometer 10 control pressure, the flush fluid enters ultrafiltration column 9, and wash ultrafiltration column 9 from down up under the pressure effect of group pump 8, partly discharge from filtering outlet 13 through the flush fluid of ultrafiltration column 9, the remainder is discharged from ultrafiltration column return port 12 and is got back to buffer tank 7 again and carries out next flushing cycle. So circulate, until the washing liquid colour that is discharged from filtering outlet 13 no longer changes, explain that ultrafiltration post 9 washs and finishes, then stop to add the washing liquid, shut down group pump 8, open valve 1, valve four 4, thoroughly discharge the washing liquid, ultrafiltration machine cleaning work is accomplished.

The utility model provides an improvement device has made following improvement, as shown in figure 1: on the basis of the original ultrafiltration equipment pipeline, a back flush loop 16 is arranged between the liquid outlet of the group pump 8 and the liquid inlet 22 of the ultrafiltration column and is connected to a reflux port 12 of the ultrafiltration column, a valve five 5 and a back flush pressure gauge 17 are arranged on the back flush loop 16, and a valve six 6 is arranged at the liquid inlet 11 of the ultrafiltration column (the dashed box in fig. 3 is the improvement).

The improved cleaning method for the ultrafiltration device provided by the invention is shown in figure 3: firstly, cleaning water is connected to enter a buffer tank 7 from an independent water inlet 15 on the buffer tank 7, the buffer tank 7 is washed through a spray ball, the washed water flows out from a water outlet behind a valve four 4, after the buffer tank 7 is cleaned, the valve four 4, a valve two 2 and a valve six 6 are closed, a valve I1 and a valve five 5 are kept opened, a group pump 8 is opened, cleaning fluid is added from the independent water inlet 15 on the buffer tank 7, the cleaning fluid flows into the group pump 8 through the buffer tank 7, the cleaning fluid pressurized by the group pump 8 flows into a back washing loop 16, the pressure is controlled through a back washing pressure gauge 17, the cleaning fluid enters an ultrafiltration column 9 from an ultrafiltration column return port 12 on the upper portion of the ultrafiltration column 9, the ultrafiltration column 9 is washed from top to bottom, and the cleaning fluid passing through the ultrafiltration column 9 is directly discharged from the water outlet behind the valve I1. When the color of the flushing liquid discharged from the water outlet is not changed any more, which indicates that the ultra-filtration column 9 is completely cleaned, the addition of the flushing liquid is stopped, the pump 8 is turned off, all the valves are kept in an open state, the flushing liquid is thoroughly discharged, and the cleaning work of the ultra-filtration machine is completed.

Ultrafiltration apparatus after the improvement is when wasing, carry out follow last washing down to the ultrafiltration column through the flush fluid, flow direction when filtering with the liquid medicine is opposite, then the residual substance of surviving in the filter membrane work side when carrying out filtering operation can be directly washed away, guarantee that the filter membrane washs thoroughly, very big improvement the abluent quality of ultrafiltration column, and need not to carry out long-time washing like before improving again, purified water and final drip washing water for injection quantity have not only been reduced, the water resource is saved, and the efficiency of ultrafiltration apparatus cleaning work has been improved.
