Detailed Description

Embodiments of the present invention are further described below with reference to the accompanying drawings:

as shown in figure 1 of the drawings, in which, fig. 2 shows, microfiltration membrane filter, including bottom open-ended container 11, the top of container 11 is equipped with filling opening 4 and leakage fluid dram 15, be equipped with filling valve 5 and leakage fluid dram 14 on filling opening 4 and the leakage fluid dram 15 respectively, the lateral wall upper end of container 11 is equipped with air inlet 12, be equipped with admission valve 13 on the air inlet 12, the top of container 11 is fixed with upper support seat 16 and motor 17, motor 17 couples to be located the inboard agitator 10 of container 11, the bottom of container 11 can be dismantled and be fixed with adapter sleeve 7, be connected with filter membrane 8 between adapter sleeve 7 and the container 11, the downside of adapter sleeve 7 is fixed with collecting hopper 6, the bottom of collecting hopper 6 is equipped with collecting opening 3, be equipped with collecting valve 2 on collecting opening 3, be equipped with washing liquid import 4 on collecting hopper 6's the lateral wall, be equipped with feed liquor valve 5 on the washing liquid import 4, the bottom of collecting hopper 6 is fixed with lower bearing seat 1.

In a preferred embodiment: the container 11 is in threaded connection with the connecting sleeve 7, so that the disassembly and the assembly are simple, and the filter membrane 8 is convenient to replace and maintain; two corresponding handles 9 are fixed on the side wall of the container 11, which is convenient for the turnover of the device.

When the device is used, the air inlet 12 is connected with a gas pipeline, during filtering, mixed liquid to be filtered is added into the container 11 from the liquid adding port 4, then the liquid adding valve 5 is closed and the air inlet valve 13 is opened, the pressure in the container 11 is increased, so that the liquid in the mixed liquid passes through the filter membrane 8, enters the liquid collecting hopper 6 and is collected through the liquid collecting port 3, and solid impurities are left on the filter membrane 8 in the container 11; during the washing, with 180 degrees of this device upset, connect the washing liquid pipeline with album liquid mouth 3, motor 17 drives the agitator 10 rotatory, open collection liquid valve 2, the washing liquid gets into collection liquid hopper 6 from album liquid mouth 3, and pass in filter membrane 8 gets into container 11, until the washing liquid fills up collection liquid hopper 6, then open flowing back valve 14, the washing liquid is discharged from drain port 15, and carry over container 11, the impurity on filter membrane 8 and the collection liquid hopper 6, because the impurity in the collection liquid hopper 6 is liquid, wash very easily, and under the stirring effect of agitator 10 and the discharge of leakage fluid dram 15, can produce the vortex in the container 1, thereby absorb the solid impurity on filter membrane 8 and the container 11 inside wall very easily, it is also very thorough to wash.

Microporous filter membrane filter, can wash container 11, filter membrane 8 and collecting hopper 6 automatically, need not artifical split one by one and wash, it is very convenient, improved the cleaning efficiency greatly.
