[0028] Figure 3 for Figure 2 Enlarged view of part A;

[0029] Figure 4 It is a schematic diagram of the filter plate structure of a composite membrane filtration device;

[0030] like Figure 1-4 As shown, a composite membrane filtration device disclosed in the present invention may include: a filtration mechanism, a fixing mechanism, a cover mechanism, a stirring mechanism and other components;

[0031] like Figure 1-4 As shown, the filtering mechanism includes a bottom plate 1, a filtering funnel 2, a liquid tank 3, an air suction nozzle 4, a filter plate 5, a mounting ring 6, and a filter hole 7;

[0032] The filter funnel 2 is arranged above the bottom plate 1, the liquid tank 3 is installed at the output end of the filter funnel 2 and the lower surface is fixedly connected to the bottom plate 1, the air suction nozzle 4 is arranged on the side of the filter funnel 2, the mounting ring 6 is arranged on the inner wall of the filter funnel 2 and is above the air suction nozzle 4, the filter plate 5 is arranged on the upper surface of the mounting ring 6 and is adapted to the filter funnel 2, and a plurality of filter holes 7 are evenly arranged on the upper surface of the filter plate 5;

[0033] The composite membrane liquid is placed in the filter funnel 2, and then the suction nozzle 4 is connected to the suction device to perform air extraction. Under the action of air pressure, the composite membrane liquid flows out through the filter holes 7 of the filter plate 5 and enters the liquid box 3. The composite membrane liquid is filtered by the filter plate 5 to achieve filtration of the composite membrane liquid. After that, the filtered composite membrane liquid can be discharged through the output end of the liquid box 3.

[0034] like Figure 1-4 As shown, the stirring mechanism includes a second motor 14, an electric push rod 15, and a stirring rod 16;

[0035] The running second motor 14 drives the stirring rod 16 to rotate through the electric push rod 15, stirs the composite membrane liquid in the filter funnel 2, speeds up its passage through the filter plate 5, and at the same time controls the extension and retraction of the electric push rod 15 to change the position of the stirring rod 16, thereby changing the stirring position of the stirring rod 16, stirring the composite membrane liquid in the filter funnel 2 at multiple positions, and enhancing its stirring effect;

[0036] The second motor 14 is arranged just above the filter funnel 2, the electric push rod 15 is installed at the driving end of the second motor 14, and the stirring rod 16 is installed at the end of the electric push rod 15;

[0037] like Figure 1-4 As shown, the cover mechanism includes a side column 8, a movable slot 9, a first motor 10, a screw 11, a threaded seat 12, an L-shaped plate 13, a second motor 14, a fixing rod 17, and an upper cover 18;

[0038] The side column 8 is installed on the upper surface of the bottom plate 1 and is located on one side of the liquid tank 3. The moving groove 9 is opened on the side of the side column 8. The first motor 10 is installed on the upper end of the side column 8. The screw 11 is rotatably installed in the moving groove 9 and the upper end is fixedly connected to the driving end of the first motor 10. The threaded seat 12 is set on the screw 11. The L-shaped plate 13 is installed on the side of the threaded seat 12. The lower surface of the second motor 14 is fixedly connected to the L-shaped plate 13. Two fixed rods 17 are correspondingly installed on the lower surface of the L-shaped plate 13. The lower ends of the two fixed rods 17 are fixedly installed with an upper cover 18. The driving end of the second motor 14 passes through the upper cover 18, and the electric push rod 15 is below the upper cover 18.

[0039] The upper cover 18 is used to cover the upper port of the filter funnel 2 to prevent the composite membrane liquid from splashing out of the filter funnel 2 during the stirring process, thereby avoiding the waste of the composite membrane liquid. When the filtration is completed, the first motor 10 runs to drive the screw 11 to rotate and drive the threaded seat 12 to rise. The rising threaded seat 12 drives the upper cover 18 to rise through the L-shaped plate 13 to open the upper port of the filter funnel 2. When the liquid is put into the filter funnel 2 for the next use, the first motor 10 drives the screw 11 to reverse and drive the threaded seat 12 to descend, thereby driving the upper cover 18 to descend and cover the port of the filter funnel 2.

[0040] like Figure 1-4 As shown, the fixing mechanism includes a fixing seat 19, a slot 20, a limit plate 21, a pull rod 22, a spring 23, and a clamp 24;

[0041] Two fixing seats 19 are installed on the side of the filter funnel 2, each card slot 20 is opened on the side of the filter plate 5 and is located on one side of the corresponding fixing seat 19, each limiting plate 21 is arranged in the corresponding fixing seat 19, each pull rod 22 is installed on the side of the corresponding limiting plate 21 and extends to the outside of the fixing seat 19, each spring 23 is sleeved on the corresponding pull rod 22, and each clamp 24 is installed on the other side of the corresponding limiting plate 21 and extends into the alignment card slot 20;

[0042] When the filter plate 5 needs to be removed and replaced, the two pull rods 22 are pulled outward to drive the two limit plates 21 to move. Each moving limit plate 21 compresses the spring 23 and drives the clamp 24 to move out of the slot 20, so that the fixation of the filter plate 5 can be released and the filter plate 5 can be taken out of the filter funnel 2. Then, the filter plate 5 with different types of filter holes 7 is placed above the mounting ring 6 in the filter funnel 2, and the two slots 20 are aligned with the two clamps 24. Then, the two pull rods 22 are released to allow the two springs 23 to rebound and drive the two clamps 24 to be clamped into the two slots 20, so that the filter plate 5 is fixed on the filter funnel 2, and the replacement is completed.
