Description

Technical Field

[0001] The utility model relates to the field of aeration equipment, in particular to a universal aerator nozzle. Background Art

[0002] Aeration is a means of strongly contacting air with water, aiming to dissolve oxygen in the air into the water, or expel unnecessary gases and volatile substances in the water into the air. In other words, it is a means of promoting the mass exchange between gas and liquid. There are many existing types, such as disk aerators, swirl aerators, tube aerators, etc. Among them, the disk aerator uses a number of nano-scale microporous structures on the disk surface to "cut" the gas and separate it into several tiny bubbles.

[0003] Among them, the bubble distribution of the existing disk aerator with a larger micropore diameter is still too concentrated (the main reason is that a relatively stable air pressure cannot be formed inside the disk aerator). After the air flow enters the inner cavity of the aerator from the air supply pipe, effective shunting cannot be carried out, and most of the air flow still exits from the middle part of the aerator ( Figure 1 as shown), resulting in less exhaust gas volume at the outer edge of the aerator and unable to achieve effective distribution of bubbles.

[0004] In summary, it is obvious that the existing technology has inconveniences and defects in actual use, so it is necessary to improve. Content of the Utility Model

[0005] Aiming at the above defects, the purpose of the utility model is to provide a universal aerator nozzle, which can realize the diversion effect on the gas while exhausting through the inclined surface of the concave structure, disperse the air flow, and achieve uniform aeration.

[0006] To achieve the above purpose, the utility model provides a universal aerator nozzle, including an aeration cover body provided with a number of micropores; a concave structure is provided on the aeration cover body, which is recessed into the inner cavity and has a pair of inclined surfaces for gas diversion; when the air flow is exhausted, part of it passes through the micropores, and the other part is driven by the inclined surface to be diverted in the upward inclined direction of the inclined surface.

[0007] According to the universal aerator nozzle of the utility model, the concave structure is a conical concave structure.

[0008] According to the universal aerator nozzle of the utility model, the concave structure is centered on the air supply hole.

[0009] According to the universal aerator nozzle of the utility model, the pore axis of the micropores located on the inclined surface forms a predetermined angle H with the inclined surface.

[0010] According to the universal aerator nozzle of the utility model, a positioning structure for positioning its shape is provided at the center of the concave structure.

[0011] According to the general aerator nozzle of the present utility model, the positioning structure includes a positioning hole provided at the center of the concave structure and a positioning member installed inside to connect the aeration hood body and the base.

[0012] The present utility model provides a general aerator nozzle, which includes an aeration hood body provided with a plurality of micropores and a base used for assembling with the aeration hood body and forming an inner cavity inside. The base is detachably connected to the aeration hood body; an air supply hole is provided on the base, and the air supply hole is connected to an air supply pipeline. When supplying air, the air supply pipeline enters the inner cavity from the air supply hole with gas and further releases it through the micropores. A concave structure that is recessed into the inner cavity and has a pair of inclined surfaces for gas diversion is provided on the aeration hood body; when the air flow is discharged from the inner cavity, part of the air flow is discharged through the micropores, and the other part of the air flow is driven by the inclined surface to be diverted in the inclined direction upward of the inclined surface, achieving the effect of air flow dispersion and avoiding the concentrated discharge of the air flow. In addition, the pore axis of the micropores located on the inclined surface of the present utility model forms a predetermined angle H with the inclined surface. The difficulty of the air flow being discharged during the diversion process is increased. Ensure the diffusion (diffusion to the outer edge of the aeration hood body) amount of the air flow. The concave structure is a conical surface concave structure, and moreover, the concave structure is centered on the air supply hole. At this time, the concave structure of the conical surface concave structure will constitute a divergent diversion distribution from the inside to the outside. Gas enters from the air inlet of the air supply hole in the middle (usually the air supply hole is located in the middle of the base), part of the air flow is discharged from the micropores in the area of the concave structure, and the other part of the air flow is diverted by the concave structure to the outer edge of the aeration hood body and discharged therefrom, realizing the uniformization of the air flow distribution. The present utility model realizes the diversion effect on the gas while discharging the air through the inclined surface of the concave structure, disperses the air flow, and realizes uniform aeration.

[0023] Preferably, in order to prevent the concave structure 2 from deforming due to the air pressure in the inner cavity and thus being unable to perform normal work, a positioning structure for positioning its shape is provided at the center of the concave structure 2 of the present utility model.
