Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

The invention aims to provide an oxygenation device, which is used for solving the problems in the prior art and can improve the water-oxygen mixing effect.

In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.

The present invention provides an oxygenation apparatus 100, as shown in fig. 1, in this embodiment, comprising: the water diversion device comprises a frame 1, a top flow guide layer 2, at least one packing layer 3 and a water diversion device, wherein the frame 1 is fixedly arranged above the water surface; the top flow guide layer 2 is fixedly arranged in the frame 1, the top flow guide layer 2 is provided with a first drain plate 21, and water flow can form a rain line through the first drain plate 21; each packing layer 3 is fixedly arranged inside the frame 1, each packing layer 3 is positioned below the top flow guide layer 2 and sequentially arranged from top to bottom at intervals, porous fillers 4 are arranged inside each packing layer 3, water flow is crushed after passing through the porous fillers 4, a second dripping and leaking plate 31 is arranged at the bottom of each packing layer 3, and the water flow can form a rain line after passing through the second dripping and leaking plate 31; the water diversion device is used for guiding water to the top diversion layer 2.
