In addition, the middle partition 420 is also used for protecting the lower diversion cutting assembly 410, and the upper diversion cutting assembly 430 is prevented from being in direct contact with the lower diversion cutting assembly 410, so that the lower diversion cutting assembly 410 is easily crushed.

The upper diversion cutting assembly 430 is used for cutting the bubbles cut by the lower diversion cutting assembly 410 again, so that the diameters of the bubbles are smaller, and the gas-liquid contact area is increased.

The upper diversion cutting assembly 430 may be a plurality of identical upper annular plates 431, the upper annular plates 431 are respectively sleeved on the air inlet pipe 200 from bottom to top in sequence, each upper annular plate 431 is provided with a plurality of upper cutting columns 432 with triangular sections, and the lower surface of the upper annular plate 431 at the lowest end is in contact with the upper surface of the middle partition plate 420.

Like this, establish the stack through overlapping upper ring plate 431 in proper order on intake pipe 200 to the installation of water conservancy diversion cutting assembly 430 is gone up in the realization, and is very convenient, and the bubble after water conservancy diversion cutting assembly 410 cuts down can contact with cutting post 432 on each, goes up cutting post 432 and can cut the bubble once more.

In addition, the length of any one of the upper cutting pillars 432 is greater than the length of any one of the lower cutting pillars 412, so that the contact area between the upper cutting pillars 432 and the air bubbles can be increased, thereby improving the cutting efficiency of the air bubbles.

Moreover, the lengths of the lower cutting posts 412 on the lower annular plates 411 are the same, and the lengths of the upper cutting posts 432 on the upper annular plates 431 are different and sequentially increase from bottom to top.

Because the ascending orbit of bubble in water is generally the back taper, so through adopting above-mentioned structure setting, the water conservancy diversion cutting structure that is more laminate with the ascending orbit of bubble, so both improved with the area of contact of bubble, improved cutting efficiency, do not influence the rising speed of bubble again, improve purifying effect to the cost has still been practiced thrift.

Moreover, the number of the lower cutting posts 412 on each lower annular plate 411 is the same, and the lower cutting posts 412 on each lower annular plate 411 and the lower cutting posts 412 on the adjacent lower annular plate 411 are arranged at equal intervals, the number of the upper cutting posts 432 on each upper annular plate 431 is the same, and the upper cutting posts 432 on each upper annular plate 431 and the upper cutting posts 432 on the adjacent upper annular plate 431 are arranged at equal intervals, and are arranged at equal intervals.
