Utility model has the beneficial effect that
After air passes through blast pipe, rubber check valve is jacked up by wind pressure by fixed bore, air is by connecing mouth
Reach rotary-cut non-return blade.Because of the vanelets that certain angle arranges on rotary-cut non-return blade, pass through formula rotary-cut non-return leaf through air
Piece is rotated, and is reached cutting air-water mixture for the first time and is formed bubble, allows rear air to pass through the double-deck rotary-cut tooth cover, by every layer
On back-off teeth cut again air-water mixture and carry out low-angle diffusion.Last air reaches diffusion pawl top plate and passes through top
Teeth staggeredly densely covered continue to cut air-water mixture and angle spread on disk, increase diffusingsurface of the microbubble in water body
Product.Air increases bubbles volume, reduces bubble diameter, keep air dissolution rate big into repeatedly cutting forms countless microbubbles excessively
Big improve reaches efficient purification of water quality purpose；When halt production, maintenance or other reasons are to carry out Air Exposure, had in water body
Part silt is precipitated.Such as without new-type rubber check valve and rotary-cut non-return blade, then silt can enter in blast pipe,
Over time blast pipe will block.Being difficult to clean up after air inlet blockage will cause aeration tank and is not available, new-type rubber non-return
Valve and rotary-cut non-return blade can automatically fall off in the case where no wind pressure and seal air intake passage, reach prevent silt enter into
The effect of air hose.
