Description

Technical Field

[0001] The utility model relates to the field of sewage treatment, in particular to an adjustable water body oxygen supply device for microbial sewage treatment. Background Art

[0002] In the prior art, when treating sewage, microorganisms are cultivated in the water to decompose the waste or harmful substances therein. However, microorganisms need a certain amount of oxygen to reproduce, and the lack of oxygen in the wastewater prevents the microorganisms from multiplying in large quantities. Therefore, it is necessary to add oxygen to the sewage. The prior art method of adding oxygen is often to directly inject oxygen into the water, resulting in the oxygen not being completely dissolved in the water or having a very low solubility.

[0003] After searching, an invention patent with publication number CN108911181A specifically discloses a water oxygen supply device for intelligent microbial sewage treatment, including a main control chip, a submersible floating device, an oxygen dissolving tank, a water inlet pump, an oxygen storage tank, a first concentration sensor for detecting preset types of microorganisms, and a second concentration sensor for detecting the concentration of pollutants to be decomposed; the main control chip is arranged in the submersible floating device, the first concentration sensor, the second concentration sensor, the oxygen dissolving tank and the oxygen storage tank are all detachably connected to the bottom of the submersible floating device, the water inlet pump is arranged on the oxygen dissolving tank for sucking water in the water body into the oxygen dissolving tank, the oxygen dissolving tank is connected to the oxygen storage tank through an air pipe, and a gas flow detector and a first solenoid valve for controlling the conduction and cutoff of the air pipe are respectively arranged in the air pipe, and a drain outlet for removing dissolved oxygen and a corresponding second solenoid valve for controlling the opening and closing of the drain outlet are arranged at the bottom of the oxygen dissolving tank.

[0004] In the above patent, the oxygen concentration of the water in the current range is judged by the concentrations of the first concentration sensor, the second concentration sensor and the fourth concentration sensor to judge whether the oxygen concentration of the water at the current depth meets the standard. If it meets the standard, the submersible floating device is controlled to adjust the water immersion depth so that oxygen can be evenly supplied at each depth, which has the effect of improving the balance of oxygen supply. However, in actual oxygen supply, oxygen is directly transported to the water body after it is produced. Since there are a large number of microorganisms in the water body, the ability of water molecules to fuse oxygen molecules is poor. This direct oxygen supply method cannot maximize the supply of oxygen to the water body, and since the oxygen supply position is fixed, the oxygen supply position cannot be adjusted according to the depth of the water body to improve the oxygen supply effect.

[0005] Therefore, it is necessary to invent an adjustable microbial sewage treatment water body oxygen supply equipment to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide an adjustable water body oxygen supply equipment for microbial sewage treatment, which drives the stirring rod to rotate through a servo motor and drives gear one through gear two, so that the internal threaded cylinder drives the external threaded cylinder to move up and down, so as to achieve the effect of stirring the water body by the stirring rod and adjusting the air outlet position of the air outlet, so as to solve the problems of low oxygen supply efficiency and inability to adjust the oxygen supply position in the prior art.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable water body oxygen supply device for microbial sewage treatment, comprising: a bearing assembly, used to carry the oxygen supply device as a whole on the water surface;

[0008] The oxygen supply regulating structure is arranged in the bearing assembly and is used for supplying oxygen to the water body.

[0009] Preferably, the bearing assembly comprises: a floating platform, four groups of floating bottles are symmetrically fixedly connected to the side of the floating platform, and an oxygen generator is installed above the floating platform.

[0011] Preferably, a stirring rod is fixedly connected below the gear, a servo motor is installed above the floating platform, and an output end of the servo motor is connected to a gear shaft.

[0012] Preferably, the internal threaded barrel is connected to an external threaded barrel via an internal thread, an air outlet is installed below the external threaded barrel, two groups of guide grooves are symmetrically opened on the inner wall of the external threaded barrel, and guide blocks are slidably connected in the guide grooves.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] The servo motor drives the gear 2 to rotate and at the same time drives the stirring rod to rotate, so that the gear 2 can stir the water body, so that the water molecules can quickly combine with the oxygen molecules, and improve the fusion of oxygen and water body. In the process of the rotation of the gear 2, the gear 1 can drive the internal threaded barrel to rotate and drive the external threaded barrel to move downward, so that the air outlet can supply oxygen at different depths, and the oxygen supply position can be adjusted.
