Technical Field

[0001] The present application relates to the technical field of aerators, and in particular to a rotary cyclone aerator. Background Art

[0002] In the sewage treatment process, aeration is a crucial step. Air is injected into the sewage to increase the dissolved oxygen content in the sewage, thereby promoting the growth of aerobic microorganisms and accelerating the decomposition of organic matter. Traditional aeration equipment usually includes an air inlet pipe, a diverter and a cutter. However, due to the fixed internal structure of the diverter, the gas distribution is uneven, which affects the oxygen transfer efficiency and treatment effect. Utility Model Content

[0003] The problem to be solved by the present application is that the existing flow divider for aerator has a fixed internal structure, which causes uneven gas distribution, thereby affecting the oxygen transfer efficiency and treatment effect.

[0013] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0014] The present application relates to a rotary cyclone aerator, such as Figure 1-6 As shown, the aerator includes a base 5 for serving as a basic support, and an air inlet pipe 4 is arranged above the base 5 and is detachably connected to the base 5 for connecting to an external air source to introduce compressed air or other gases. The upper part of the base 5 is also provided with a diverter component 2 which is connected to the air inlet pipe 4 so as to evenly distribute the introduced gas. In order to enhance the sufficient mixing between the gas and the water body, a cutter 1 for generating fine bubbles to enhance the oxygen dissolution efficiency is also arranged above the diverter component 2. When the aerator is in use, the diverter component 2 and the cutter 1 can be effectively fixed to the base 5 and can be easily increased or decreased. Therefore, a plurality of pull plate components 3 for applying circumferential positioning operations to the diverter component 2 and the cutter 1 are arranged around the upper part of the base 5. In order to enhance the uniformity of gas distribution, the diverter component 2 adopts a rotatable structure to drive the gas to move inside it to achieve uniform distribution of the gas.

[0015] Since the aerator is arranged vertically, in order to achieve effective air intake operation of the air intake pipe 4, the air intake pipe 4 is composed of two sections of pipe bodies that are arranged perpendicular to each other and connected.

[0016] The flow dividing assembly 2 comprises a flow dividing cylinder 12, a partition 11, a core rod 13 and a support rod 10. The flow dividing cylinder 12 is a straight hollow structure. The partition 11 which plays a guiding role and is arranged obliquely is arranged in a mirror-symmetrical manner inside the flow dividing cylinder 12. The core rod 13 which is arranged concentrically with the partition 11 is arranged at the axial center of the flow dividing assembly 2. The side of the core rod 13 is connected to the partition 11, so that the impact resistance of the partition 11 can be improved and the gas can be evenly distributed. In order to realize the rotation operation of the partition 11, the upper and lower ends of the core rod 13 are symmetrically arranged with rod caps 14 which are concentrically connected with the core rod 13. The upper part of the rod cap 14 is arranged There is a support rod 10 connected to the splitter tube 12 and placed horizontally inside the splitter tube 12, so that when the gas enters along the bottom of the splitter tube 12, it impacts the surface of the inclined partition 11, and then can drive the partition 11 to rotate, and the core rod 13 can stably rotate under the support of the support rod 10. In order to further improve the uniform distribution of the gas, a guide bar 16 that can play a guiding role is arranged on the surface of the partition 11, and a spiral groove 15 is also arranged on the upper part of the inner wall of the splitter tube 12, so that the gas can achieve vortex rise and uniform dispersion under the action of the guide bar 16 and the groove 15.

[0017] The cutter 1 comprises a cutting barrel 6 and a mushroom head 7. The cutting barrel 6 is a straight hollow structure. A plurality of mushroom heads 7 are evenly arranged in the circumferential direction inside the cutting barrel 6 for cutting the gas to improve the mixing efficiency.

[0018] The pull plate assembly 3 includes a vertical plate 8 and a horizontal plate 9. The vertical plates 8 are symmetrically arranged along the vertical direction of the aerator. The inner side walls of the vertical plates 8 are respectively abutted against the diversion cylinder 12 and the cutting cylinder 6, and the bottom side walls of the vertical plates 8 are abutted against the air inlet pipe 4. In order to effectively fix the vertical plates 8, a horizontal plate 9 that is clamped with the vertical plates 8 is also arranged on the upper part of the air inlet pipe 4, so that the fixing operation of the vertical plates 8 is realized with the help of the horizontal plate 9.

[0019] When in use, the aerator is immersed in the water body, and the gas enters the inside of the diversion component 2 along the air inlet pipe 4, and then under the action of the partition 11 and the core rod 13 of the diversion component 2, it flows upward evenly and contacts with the water body. In the process of the gas rising, it will collide with the inclined partition 11 and drive it to drive the core rod 13 to rotate synchronously, and the core rod 13 benefits from the rod caps 14 and the support rods 10 arranged at both ends to achieve stable supporting operation, and further with the help of the guide bars 16 and the grooves 15, the gas can achieve both swirling rise and uniform distribution. As the gas continues to rise, it will collide with the mushroom head 7 of the cutter 1, causing the gas to burst, thereby increasing the contact area with the water body, so that the gas can fully contact with the water body, which can not only promote the oxidation and decomposition of organic matter in the water body, but also increase the dissolved oxygen content of the water body, which is beneficial to the subsequent growth and reproduction of microorganisms.

[0020] It is to be understood that the present application is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present application. In addition, under the guidance of the present application, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present application.
