When the impurities accumulate to a certain amount, the filtration efficiency will be affected. At this time, the through hole 211 of the new filter membrane 24 is connected to the discharge port 12 of the storage chamber 1 by rotating the turntable 21, and the old filter membrane 24 is away from the discharge port 12. The old filter membrane 24 is then replaced, so that the filter membrane 24 can be replaced without stopping the machine, thereby improving production efficiency.
[0030] like Figure 2 , Figure 3 , Figure 4As shown, in some embodiments, a first annular slide 213 is provided on the upper surface of the turntable 21, and a first slide 221 is provided at the lower end of the feed pipe 22; the first slide 221 is slidably arranged in the first annular slide 213; when the turntable 21 rotates, the first slide 221 moves along the first annular slide 213, driving the feed pipe 22 to communicate with other through holes 211, and in the process of converting the through holes 211, the first slide 221 first covers the new through hole 211, and then connects the feed pipe 22 with the new through hole 211 as it moves, to prevent leakage during the conversion process, and at the same time, a seal is also provided on the lower surface of the first slide 221 to prevent leakage.
[0031] In some embodiments, a second annular slide 214 is provided on the lower surface of the turntable 21, and a second slide 231 is provided at the upper end of the discharge pipe 23; the second slide 231 is slidably arranged in the second annular slide 214; wherein, the setting principle of the second annular slide 214 and the second slide 231 is the same as that of the first annular slide 213 and the first slide 221.
[0032] In some embodiments, a connecting shaft 25 is provided at the axis center of the upper surface of the turntable 21, and the connecting shaft 25 is connected to the lower surface of the storage chamber 1. The turntable 21 is rotatably set on the connecting shaft 25, and the upper end of the feed pipe 22 is connected to the discharge port 12 of the storage chamber 1, which can be but not limited to a hose connection; when the turntable 21 is rotated, the feed pipe 22 moves along the first annular slideway 213, and after moving a certain distance, the feed pipe 22 is blocked.
