first circular truncated cone blocks 3 are close to each other to return to the state shown in the figure 1 according to the same working principle, then the trapezoidal block 14 can be directly taken out from the cylinder 9, so that the first circular truncated cone block 3 and the water pipe 5 which are connected with the bottom surface of the trapezoidal block 14 through the connecting rod 15 are synchronously taken out, and then the damaged elements inside the device can be effectively maintained and replaced, the device is designed, and the existing complicated fixing structure is effectively avoided, make when the internal element replaces, it is extremely inconvenient, lead to the operation longer, work efficiency is lower, and easy dismounting like this, can clear up second circle platform piece 22 lateral wall, avoid long-term the use, make second circle platform piece 22 side adhere to impurity, make second circle platform piece 22 can not effectually play sealed effect after collecting a lot of, and the dismouting also makes things convenient for like this to replace the rubber seal on second circle platform piece 22 lateral wall, ensure that second circle platform piece 22 can effectually play sealed effect, also make things convenient for the later stage to maintain and replace its filter screen 18 like this simultaneously.
