In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings needed to be used in the description of the embodiments or the prior art will be briefly described below, it is obvious that the drawings in the following description are only some embodiments of the present invention, and for those skilled in the art, other drawings can be obtained according to these drawings without inventive exercise.
Fig. 1 is a schematic structural diagram of the present invention.
In the figure, a high-level water tank-10, a water outlet-11 and an electric valve-12 are arranged; a drop runner-20, a baffle-21 and saw teeth-22; a water collecting tank-30, a water outlet-31 and an oxygen dissolving instrument-32; an automatic control cabinet-40.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
As shown in fig. 1, the drop-down type oxygenating apparatus according to the embodiment of the present invention includes a drop flow channel 20 in a step shape, a high level water tank 10 is disposed above the top end of the drop flow channel 20, and a water collecting tank 30 is disposed below the bottom end of the drop flow channel 20.
The high-level water tank 10 is arranged at a position 1-1.5 m away from the ground, and a water outlet 11 is formed below the side wall of the high-level water tank. An electric valve 12 is arranged at the water outlet 11 and used for controlling the flow of the water body; the electric valve 12 is electrically connected with the automatic control cabinet 40.
The drop runner 20 is located below the water outlet 11. The drop runner 20 is an open runner, which facilitates the water body to contact with air when flowing. Because the drop runner 20 is in a step shape, the drop time of the water body is longer than that of a vertical drop mode, so that the water body is more fully contacted with the air. Meanwhile, the baffle 21 is arranged at the 90-degree vertex angle of each step, the included angle between the baffle 21 and the vertical direction is 30-60 degrees, and the sawteeth 22 are arranged on the outer surface of the baffle 21, so that the distribution of water flow of each step on the drop flow channel 20 is more uniform, and the dissolved oxygen efficiency is improved.
The water collection tank 30 is placed directly on the ground below the bottom end of the drop runner 20.

High-precision dissolved oxygen is arranged in the water collecting tank 30, and the water collecting tank is provided with an oxygen dissolving instrument 32, wherein the oxygen dissolving instrument 32 is electrically connected with the automatic control cabinet 40. The automatic control cabinet 40 is used for automatically adjusting the on-off of the electric valve 12 according to the set value of the dissolved oxygen so as to control the flow of the water body, thereby automatically and accurately controlling the concentration of the dissolved oxygen in the water collection tank 30.
When the device is used, after the water in the high-level water tank 10 flows out from the water outlet 11, the water flows into the top end of the drop flow channel 20 by utilizing the self gravity, and in the process of flowing through the stepped drop flow channel 20, oxygen in air is sucked into the water, so that the oxygenation process of the water is completed. Then, the water falls into the water collecting tank 30 through the bottom end of the drop runner 20, and is finally discharged through the water discharge port 31.
The utility model provides a drop-out oxygenating device utilizes the gravity of water self to make it fall to low from the high position to in falling the in-process and rolling up the dissolved oxygen in the air and inhaling the water, need not to accomplish the oxygenation process with the help of other power, not only practiced thrift production and use cost, still reducible energy consumption. Meanwhile, the drop flow channel in the oxygenating device is stepped, and the vertex angle of each step is provided with the serrated baffle, so that the oxygenating time is prolonged, and the water flow of each step is distributed more uniformly, so that the water body is in more sufficient contact with the air, and the oxygen dissolving efficiency is higher.
