Pass the tube aerator petal type attachment device of efficiency.
In order to solve the above technical problems, technical solution adopted in the utility model is:
A kind of tube aerator petal type attachment device, including connecting tube, be vertically installed in connecting tube and for circular arc
The grafting supporting plate of shape and the insertion pipe being installed on grafting supporting plate；One is respectively coaxially arranged in the both ends nozzle of the connecting tube
The current divider for flowing out air only along the inner tubal wall of connecting tube.
Further, the current divider includes for being inserted in connecting tube and for cylindrical inserting column and being fixed on outside inserting column
The circular baffle plate of end, the diameter of baffle is less than the outer diameter of connecting tube and is greater than the diameter of inserting column, on the shaft of inserting column and along it
It is circumferentially uniformly provided with multiple diversion trenches, the outer end of inserting column and is installed with cushion block between two neighboring diversion trench.
Further, the axis of the insertion pipe and the axis of the axis of connecting tube and grafting supporting plate are vertical.
Further, a pair of fixed plate with jack is respectively installed on the axial ends outer wall of the grafting supporting plate.
Further, its periphery for being located at insertion pipe offers seal groove on the grafting supporting plate.
Further, the internal diameter of the grafting supporting plate is equal to the outer diameter of air supply pipe, and the outer diameter of insertion pipe, which is equal to, is opened in confession
The aperture of air vent on tracheae tube wall.
Further, the connecting tube, grafting supporting plate and insertion pipe are an integral structure.
Further, the diversion trench is opened up each along the axial direction of inserting column.
Further, the diversion trench extends to its outer end by the inner end of inserting column.
Further, the inserting column, baffle and cushion block are an integral structure.
The beneficial effects of adopting the technical scheme are that
A current divider is respectively coaxially arranged in the both ends nozzle of the connecting tube of the utility model, current divider makes air straight
It connects on the inner surface for being delivered to aeration tube, accelerates the diffusion velocity into water body, improve the efficiency of oxygen transmitting.
