Abstract
Description
Technical Field
[0001] This utility model relates to the field of cyclone aerator technology, and more specifically, to the anti-clogging diffuser head of a cyclone aerator for sewage treatment. Background Technology
[0002] A cyclone aerator is a highly efficient water treatment device, mainly used to inject dissolved oxygen into water. Through the rotation of the airflow, air or oxygen is effectively mixed into the water, increasing the oxygen content in the water and promoting the aerobic degradation process of microorganisms.
[0003] Existing aerators cut bubbles by stirring in one direction. However, when the aerator rotates, it causes the bubbles to flow with it, resulting in some bubbles not being cut and becoming smaller, which affects the dissolved oxygen utilization rate of the mud-water mixture.
[0004] A search revealed that Chinese patent CN222498883U discloses a vortex aerator. By rotating the lower and upper dividing components in two directions, it can prevent water from rotating in one direction, thus preventing bubbles from following the flow and being unable to be properly cut, improving the cutting and tearing effect of bubbles, and ensuring the dissolved oxygen utilization rate of the mud-water mixture.
[0005] In actual use, the aforementioned swirl aerator is prone to encountering various impurities and particulate matter when treating wastewater. These substances tend to accumulate at the diffuser head, causing blockage. Blockage reduces the amount of oxygen output by the aerator, affecting the dissolved oxygen content in the water. Utility Model Content

[0009] The cylinder and the outside of the diffuser head are provided with a disassembly mechanism.
[0010] By adopting the above technical solution, a strong swirling and turbulent flow can be generated in the gas-liquid mixture inside the cylinder, which facilitates the gas-liquid mixing and oxygen dissolution process.

Multiple fixing rods are fixedly connected to the outside of the connecting discs. A cutting blade is fixedly connected to one end of each fixing rod.
[0012] By adopting the above technical solution, the accumulation and residence time of impurities in the gas-liquid mixture inside the diffuser head can be effectively reduced, thereby reducing the occurrence of blockage.
[0013] As a further description of the above technical solution: the disassembly mechanism includes a connecting ring, which is fixedly connected to the outside of the cylinder. Two sliding grooves are formed on the upper surface of the connecting ring. Two threaded rods are threadedly connected inside the connecting ring. Two insert rods are fixedly connected to the outside of the diffuser head. The insert rods are slidably connected to the inside of the sliding grooves.

[0014] By adopting the above technical solution, the installation and disassembly process of the diffuser head and the cylinder becomes efficient and convenient, and the disassembly and installation work can be completed quickly.
[0015] The technical effects and advantages of this utility model are as follows:
[0016] 1. By setting up anti-clogging components, compared with existing technologies, the spiral guide vanes can guide the gas-liquid mixture to form an orderly swirling motion, and the spiral blades can use centrifugal force to accelerate the flow of the gas-liquid mixture. Multiple cutting blades can cut and stir the gas-liquid mixture, which can effectively reduce the accumulation and residence time of impurities in the gas-liquid mixture inside the diffuser head, thereby reducing the occurrence of clogging.
[0017] 2.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] The embodiments disclosed in this application are as follows: Figure 1-6 The anti-clogging diffuser head of the swirl aerator for wastewater treatment shown includes a cylinder 1, a flange air inlet 2 fixedly connected to one side of the cylinder 1, a support plate 3 fixedly connected inside the cylinder 1, a bubble generator 5 rotatably connected to the bottom end of the support plate 3, multiple rotating guide plates 6 fixedly connected to the bottom end of the bubble generator 5, a vertical guide plate 7 fixedly connected to the bottom end of the rotating guide plate 6, a first connecting rod 4 fixedly connected to the bottom end of the bubble generator 5, a turntable 8 fixedly connected to the bottom end of the first connecting rod 4, multiple vortex blades 9 fixedly connected to the outside of the turntable 8, and a diffuser head 10 provided at the top of the cylinder 1, with an anti-clogging component installed inside the diffuser head 10.
[0028] A disassembly mechanism is provided on the outside of the cylinder 1 and the diffuser head 10. Under the combined action of the rotating guide plate 6, the vertical guide plate 7, the turntable 8 and the vortex blades 9, the gas-liquid mixture generates strong swirling and turbulence in the cylinder 1. The bubble generator 5 cuts the air into tiny bubbles, which increases the contact area between the bubbles and the sewage liquid, thereby increasing the dissolved oxygen content in the water.
[0029] Reference Figure 4 and 5 As shown, the anti-clogging component includes a spiral guide vane 11, which is fixedly connected to the inside of the diffuser head 10. A second connecting rod 12 is rotatably connected to the top of the support plate 3. Multiple support rods 13 are fixedly connected to the outside of the second connecting rod 12. A spiral blade 14 is fixedly connected to one end of the support rod 13. Multiple connecting discs 15 are fixedly connected to the outside of the second connecting rod 12. Multiple fixing rods 16 are fixedly connected to the outside of the connecting discs 15. A cutting blade 17 is fixedly connected to one end of the fixing rod 16. The spiral action of the spiral guide vane 11 can provide guidance for the gas-liquid mixture. When the sewage fluid swirls and rotates inside the cylinder 1, it can drive the second connecting rod 12 to rotate, so that the second connecting rod 12 can drive the spiral blade 14 to rotate. The conical spiral action of the spiral blade 14 can drive the gas-liquid mixture to be transported upward, thereby reducing the accumulation of the gas-liquid mixture inside the diffuser head 10. At the same time, the multiple cutting blades 17 can cut and stir the gas-liquid mixture, which can effectively reduce the accumulation and residence time of impurities in the gas-liquid mixture inside the diffuser head 10, thereby reducing the occurrence of clogging.
[0030] Reference Figure 6 and 7 As shown, the disassembly mechanism includes a connecting ring 18, which is fixedly connected to the outside of the cylinder 1. Two sliding grooves 19 are formed on the upper surface of the connecting ring 18. Two threaded rods 20 are threadedly connected inside the connecting ring 18. Two insert rods 21 are fixedly connected to the outside of the diffuser head 10. The insert rods 21 are slidably connected to the inside of the sliding grooves 19. The insert rods 21 are threadedly connected to the threaded rods 20 inside. By using the two insert rods 21 to slide inside the sliding grooves 19, the diffuser head 10 can move smoothly along a predetermined path when installed with the cylinder 1, reducing misalignment or jamming. The two threaded rods 20 limit the insertion rods 21 and the connecting ring 18, which can realize the quick disassembly and installation of the cylinder 1 and the diffuser head 10.
[0031] Working principle of this utility model: This utility model designs an anti-clogging diffuser head for a cyclone aerator used in wastewater treatment. The specific structure is shown in the attached instruction manual. Figure 1-6As shown, in this technical solution, through the cooperation of various structures, when compressed air enters the cylinder 1 through the flange inlet 2, it first mixes with the sewage fluid at the bottom of the cylinder 1 to form a gas-liquid mixture. Then, under the combined action of the rotating guide plate 6, the vertical guide plate 7, the turntable 8, and the vortex blades 9, the gas-liquid mixture generates strong swirling and turbulent flow within the cylinder 1. Simultaneously, the bubble generator 5 cuts the air into tiny bubbles, increasing the contact area between the bubbles and the sewage liquid. Afterward, the fully mixed gas-liquid mixture leaves the cylinder 1 at a high velocity and forms a circulating flow around it. The spiral guide vanes 11 inside the diffuser head 10 can provide guidance for the gas-liquid mixture to leave the cylinder 1. At the same time, the second connecting rod 12 is rotatably connected to the support plate 3, so that when the sewage fluid swirls and rotates inside the cylinder 1, it can drive the second connecting rod 12 to rotate. The second connecting rod 12 can drive the spiral blades 14 to rotate through multiple support rods 13. The conical spiral blade 14 accelerates the upward transport of the gas-liquid mixture, reducing its accumulation inside the diffuser head 10. Simultaneously, the second connecting rod 12 drives multiple connecting discs 15 to rotate, which in turn drives the fixed rod 16 to rotate. This intensely agitates the wastewater fluid inside the diffuser head 10, reducing bubble accumulation and breaking up impurities and bubbles within the gas-liquid mixture to minimize blockage. When disassembling and cleaning the diffuser head 10, the two threaded rods 20 are rotated sequentially to separate them from the insert rods 21. The diffuser head 10 is then rotated, causing the two insert rods 21 to slide within the groove 19. When the two insert rods 21 rotate to one end of the groove 19, they pull the diffuser head 10 upward, separating it from the cylinder 1 for cleaning the inside of the diffuser head 10 and the spiral blade 14.

Electrical control components not mentioned in this technical solution are existing technologies and are therefore not shown in the figures and will not be described here.
