Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of aeration equipment for sewage treatment, and in particular to a vortex aerator with rotating internal components. Background Technology
[0002] A cyclone aerator is a device used for water and wastewater treatment. Its main function is to introduce air into the water to increase the dissolved oxygen concentration. It generally works by using a cyclone to fully mix air and water, thereby improving the oxygen transfer efficiency.
[0003] Currently, cyclone aerators are installed inside water bodies, often through a single air inlet pipe. After the air is guided by the aerator, the gas is cut through the top and discharged in a vortex. However, the airflow path is singular and fixed. Over time, this fixed airflow path can cause particle accumulation inside the wastewater, reducing the overall effect. In addition, the internal component structure of existing cyclone aerators is relatively fixed. The main cutting and swirling rely on the fixed structure. When the airflow is split, it is easy to cause uneven airflow and make it difficult to maintain the overall mixing effect. Furthermore, if the airflow is too fast, the airflow cannot be fully cut. High-speed flow may lead to hydrodynamic instability, such as separation flow, eddies, and shock waves. The mixing degree between gas and liquid is insufficient, and the dissolved oxygen transfer rate will also be worse. Utility Model Content
[0004] The purpose of this invention is to address the deficiencies in the existing technology by proposing a swirl aerator with rotating internal components.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A cyclone aerator with rotating internal components includes a cylindrical body, an air outlet at the top of the cylindrical body, and a plurality of evenly distributed gas cutters at the top of the cylindrical body.
[0007] The bottom of the cylinder is provided with a rotating guide mechanism that divides the airflow by rotation. One side of the rotating guide mechanism is provided with a bidirectional air intake structure that cooperates with it to form two air intake channels. Inside the cylinder is a central support cylinder that cooperates with the rotating guide mechanism. The top of the central support cylinder is provided with a flow guide sleeve, which is located below the gas cutter.
[0008] Furthermore, the bidirectional air intake structure includes a first air intake pipe and a second air intake pipe, which are connected to the same main air intake pipeline. The outlet end of the second air intake pipe is located inside the central support cylinder and intakes air along the tangential direction of the central support cylinder. The outlet end of the first air intake pipe is located between the central support cylinder and the cylinder body and intakes air along the axial direction of the central support cylinder.
[0009] Furthermore, the rotary guide mechanism includes a rotary sleeve, and a plurality of diverter plates are distributed equidistantly in an annular shape at the bottom of the rotary sleeve;
[0010] The top of the rotating sleeve is provided with a rotating fitting frame, and the rotating sleeve is fitted onto the bottom of the central support cylinder. The rotating sleeve drives the diverter plate and the rotating fitting frame to rotate simultaneously.
[0011] Furthermore, the flow divider is a plate structure inclined to the central axis of the rotating sleeve, the rotation trajectory of the flow divider is tangent to the air intake direction of the second air intake pipe, and the air intake point of the second air intake pipe corresponds to the side wall of the flow divider.
[0012] Furthermore, the rotating mating frame is a hollow conical structure, the maximum diameter of the rotating mating frame is smaller than the inner diameter of the cylinder, and the top of the rotating mating frame is provided with several guide grooves.
[0013] Furthermore, the bottom end of the rotating mating frame is provided with a number of evenly distributed rotating cutting blades, which are arc-shaped plates and are distributed equidistantly in a ring on the circumference of the bottom wall of the rotating mating frame.
[0014] Furthermore, the top of the cylinder is provided with several air holes, which are connected to the internal space of the cylinder.
[0015] Furthermore, the outer wall of the flow guide sleeve is provided with spirally distributed flow guide plates, and the top end of the flow guide sleeve is provided with an adjusting cap, which is installed on the flow guide sleeve by a telescopic rod.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] By optimizing the airflow path through multiple air intake channels, the dual-channel design reduces airflow resistance and improves the overall aerodynamic efficiency of the system. Furthermore, it can be combined with a rotating structure to dynamically adjust the airflow direction, thereby achieving flexible flow distribution and a more uniform airflow distribution. In addition, the rotating internal structure can guide the airflow, help form vortices to ensure thorough mixing of air and water, increase the gas-liquid contact area, and effectively cut the airflow, reducing impurity deposition. This expands the ways to process the airflow and ensures the stability and uniformity of the entire gas flow process. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1
[0028] Reference Figure 1-5A cyclone aerator with rotating internal parts includes a cylinder 1, an air outlet 2 at the top of the cylinder 1, and several evenly distributed gas cutters 3 at the top of the cylinder 1.
[0029] The bottom of the cylinder 1 is provided with a rotating guide mechanism 4 that divides the airflow by rotation. The rotating guide mechanism 4 has a rotatable structure and is located at the air inlet position at the bottom. It can pre-divide the incoming airflow and guide the airflow direction by rotation, so that the airflow can flow smoothly from the bottom to the outlet 2 and be discharged, so that water and oxygen can be better mixed.
[0030] The rotary guide mechanism 4 is provided with a bidirectional air intake structure 5 on one side to form two air intake channels, and one of the channels can cause the rotary guide mechanism 4 to rotate.
[0031] The cylinder 1 has a central support cylinder 6 inside that cooperates with the rotation guide mechanism 4. The top of the central support cylinder 6 is provided with a flow guide sleeve 7. The flow guide sleeve 7 is located below the gas cutter 3. The flow guide sleeve 7 is used to guide the airflow to rotate. After the airflow rotates, it is cut by the gas cutter 3 to generate swirling bubbles, which finally flow out through the gas outlet 2.
[0032] The bidirectional air intake structure 5 includes a first air intake pipe 8 and a second air intake pipe 9. The first air intake pipe 8 and the second air intake pipe 9 are connected to the same main air intake pipeline. The outlet end of the second air intake pipe 9 is located inside the central support cylinder 6, and air is introduced along the tangential direction of the central support cylinder 6. The outlet end of the first air intake pipe 8 is located between the central support cylinder 6 and the cylinder body 1, and air is introduced along the axial direction of the central support cylinder 6. The first air intake pipe 8 and the second air intake pipe 9 are used to distribute the air from the main air intake pipeline to the device, forming two air intake channels. The air intake channels enter the device from the inside and outside of the central support cylinder 6, respectively. The different positions of the channels can reduce the situation where the airflow velocity of the main pipeline is too fast, and will not reduce the final air output effect.
[0033] Example 2
[0034] Reference Figure 1-5 Based on Embodiment 1, the rotating guide mechanism 4 includes a rotating sleeve 10, and a plurality of flow dividers 11 are distributed equidistantly in an annular shape at the bottom of the rotating sleeve 10. The flow dividers 11 are used to initially disperse the intake airflow and guide the flow direction of the airflow.
[0035] The top of the rotating sleeve 10 is provided with a rotating fitting frame 12. The rotating sleeve 10 is fitted onto the bottom of the central support cylinder 6. The rotating sleeve 10 drives the flow divider 11 and the rotating fitting frame 12 to rotate simultaneously. After the flow divider 11 and the rotating fitting frame 12 rotate simultaneously, the effect of the rotating guide mechanism 4 on airflow division and dispersion is enhanced. Furthermore, because the airflow drives the rotation of the rotating guide mechanism 4, kinetic energy loss occurs, reducing the phenomenon of excessive airflow speed. At the same time, it creates a speed difference between the airflow inside and outside the rotating sleeve 10, achieving different swirling cutting effects. When the external airflow and the internal airflow merge, the faster airflow compensates for the slower airflow speed difference, keeping the overall airflow speed stable and allowing it to fully diffuse into the water, increasing dissolved oxygen in the water, and promoting water circulation and mixing.
[0036] The diverter plate 11 is a plate structure inclined to the central axis of the rotating sleeve 10. The rotation trajectory of the diverter plate 11 is tangent to the air intake direction of the second air intake pipe 9, and the air intake point of the second air intake pipe 9 corresponds to the side wall of the diverter plate 11. The rotating fitting frame 12 is a hollow conical structure. The maximum diameter of the rotating fitting frame 12 is smaller than the inner diameter of the cylinder 1. The top of the rotating fitting frame 12 is provided with several guide grooves 13. The bottom end of the rotating fitting frame 12 is provided with several evenly distributed rotating cutting blades 14. The rotating cutting blades 14 are arc-shaped plates and are equidistantly distributed in a ring on the circumference of the bottom wall of the rotating fitting frame 12.
[0037] It is easy to see from the above design that the diverter plate 11 can make full use of the power of the air intake channel of the second air intake pipe 9. The air intake of the second air intake pipe 9 is used as the rotational power to make the rotating sleeve 10 rotate, thereby driving the rotating mating frame 12 to rotate. At the same time, the inclined structure can guide the airflow to the side wall of the ejection cylinder 1 and the rotating sleeve 10, so that it flows upward and enters the conical structure at the bottom of the rotating mating frame 12. The conical structure at the bottom of the rotating mating frame 12 can gather part of the airflow and flow out from the guide groove 13 at a higher flow rate to form a third flow channel. This flow channel is close to the outer wall of the rotating sleeve 10 and flows at a higher flow rate. The remaining airflow that is not gathered will be divided by the rotating cutting blade 14 and guided upward from the circumferential side as it rotates. The high-speed airflow flowing out of the guide groove 13 can also accelerate the rise of these airflows through a higher flow rate, so that the airflow is effectively dispersed and cut.
[0038] Furthermore, the rotatable nature of the rotating sleeve 10 can prevent blockage inside the device, prevent solid particles from accumulating inside the aerator by promoting dispersion, and prevent excessive energy loss after converting the energy of the intake air into rotational power. The rotating structure can generate swirling flow at the bottom, which allows the air and liquid entering the aerator to mix more thoroughly, increases the dispersion of bubbles, and thus improves the oxygen transfer efficiency.
[0039] Example 3
[0040] Reference Figure 1-5 Based on the above embodiments, the top of the cylinder 1 is provided with a plurality of air holes 15, which are connected to the internal space of the cylinder 1.
[0041] The outer wall of the guide sleeve 7 is provided with spirally distributed guide plates 16, and the top of the guide sleeve 7 is provided with an adjusting cap 17. The adjusting cap 17 is installed on the guide sleeve 7 through a telescopic rod 18. The airflow generated by the first air inlet pipe 8 is dispersed by the air hole 15 at the top and diffuses from the inside to the outside. When the flow rate is too fast, the telescopic rod 18 of the adjusting cap 17 is pushed up by the pressure of the airflow generated by the first air inlet pipe 8, and the adjusting cap 17 will generate an exhaust gap at the bottom, thereby reducing the current excessively high gas flow rate. When the airflow rate remains stable, the pressure decreases, the adjusting cap 17 will fit against the rotating guide sleeve, and the airflow will flow out from the air hole 15, and after passing through the guide plate 16, it will be dispersed and flow out.
[0042] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
