Description

Technical Field

[0001] This utility model relates to the field of aerator technology, specifically to an inverted umbrella-shaped surface aerator. Background Technology

[0002] As is well known, existing surface aerators are core equipment in wastewater treatment, aquaculture, and industrial water circulation systems. Their function is to mechanically agitate the water to promote the contact between oxygen and water, thereby increasing the dissolved oxygen content and ensuring the activity of microorganisms or the needs of biological metabolism.

[0003] Traditional surface aerators mostly adopt a fixed structure, which achieves aeration by rotating blades or discs striking the water surface. However, they have significant limitations in terms of installation adaptability, operational stability and ease of maintenance.

[0004] Specifically, the main structure of early aerators was usually a rigid fixed design, which could not be adjusted according to changes in pool depth or operating range. In water treatment scenarios with seasonal water level fluctuations, aerators needed to be frequently disassembled to adjust the installation height, resulting in increased downtime and higher maintenance costs. In addition, the motor drive components of traditional equipment were mostly directly exposed to a humid environment, and water vapor corrosion could easily cause short circuits or bearing corrosion, significantly shortening the equipment's lifespan. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this utility model provides an inverted umbrella-shaped surface aerator.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an inverted umbrella-shaped surface aerator, comprising a fixed plate, a distance adjustment component at one end of the fixed plate, a telescopic component at the lower end of the fixed plate, a protective box component at the lower end of the telescopic component, a rotating motor inside the protective box component, a rotating shaft at the lower end of the protective box component, blades at the lower end of the rotating shaft, and the upper end of the rotating shaft connected to the output end of the rotating motor.

[0009] To improve installation efficiency and structural compactness, the present invention includes the following improvements: the distance adjustment assembly includes an extension plate, a damping slide rail, and a damping slider. A groove is provided on one side of the fixing plate, the damping slide rail is symmetrically arranged on both sides of the groove and fixedly connected thereto, the damping slider passes through the damping slide rail and is damped and slidably connected thereto, the extension plate is located between the two damping sliders, and a matching fixing screw is provided at one end of the extension plate.

[0010] To achieve automated adjustment of the telescopic height, this utility model improves upon the following: the telescopic assembly includes a control motor, a support box, a threaded rod, a telescopic rod, and a stop block. The support box is located on the lower side of one end of the fixed plate. The control motor is located on the upper side wall of the fixed plate. The threaded rod passes through the support box and the fixed plate and is connected to the output end of the control motor. The telescopic rod is located on the threaded rod, passing through it and threadedly connected to it. The telescopic rod is fitted and slidably connected to the inner side wall of the support box. The bottom wall of the support box has an opening that matches the telescopic rod. The stop block is located at the upper end of the telescopic rod and matches the support box.

[0011] To prevent moisture and impurities from entering, the present invention is improved as follows: the protective box assembly includes a waterproof box and a sealing plate, the waterproof box has a cavity, the rotating motor is inside the cavity, and the sealing plate is on the front side wall of the cavity and is sealed to it.

[0012] To optimize fluid shear force, the present invention includes the following improvements: the blade is made of titanium alloy with a parabolic cross-section and a titanium nitride coating formed on its surface by plasma spraying.

[0013] To accelerate the dissipation of heat from the motor, the present invention includes the following improvement: multiple sets of heat dissipation fins are provided on the inner side wall of the waterproof box.

[0014] To support wireless control and parameter setting, the present invention is improved by having a built-in remote control system for the aerator.

[0015] To improve the guiding accuracy and vibration resistance during the adjustment process, the present invention is improved by setting the cross-section of the damping slide and the damping slider to be T-shaped.

[0016] (III) Beneficial Effects

[0017] Compared with the prior art, this utility model provides an inverted umbrella-shaped surface aerator, which has the following beneficial effects:

[0018] This inverted umbrella-shaped surface aerator is equipped with a telescopic component. By controlling the threaded transmission between the threaded rod and the telescopic rod driven by the motor, the blade height can be infinitely adjusted. This allows it to quickly adapt to different water depths and prevents the telescopic rod from falling off through the limiting action of the stop block and the support box, ensuring a stable and reliable lifting process.

[0019] The distance adjustment component uses a dynamic combination of a damping slider and a slide rail, allowing the extension plate to slide laterally along the fixed plate and lock its position with fixing screws. This not only meets the installation requirements for changes in the width of the pool edge, but also counteracts the vibration displacement caused by water flow impact through damping resistance, avoiding frequent manual calibration.

[0020] The protective box assembly adopts a combined sealing design of waterproof box and sealing plate to form a multi-level waterproof barrier, effectively isolating sewage and water vapor from corroding the rotating motor and greatly reducing the motor failure rate. Attached Figure Description

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0029] Please see Figure 1-4A type of inverted umbrella-shaped surface aerator includes a fixed plate 1. A distance adjustment component is provided at one end of the fixed plate 1, and a telescopic component is provided at the lower end of the fixed plate 1. A protective box assembly is provided at the lower end of the telescopic component, and a rotating motor 11 is housed within the protective box assembly. A rotating shaft 9 is provided at the lower end of the protective box assembly, and blades 10 are provided at the lower end of the rotating shaft 9. The upper end of the rotating shaft 9 is connected to the output end of the rotating motor 11. The telescopic component includes a control motor 2, a support box 5, a threaded rod 12, a telescopic rod 6, and a stop block 13. The support box 5 is located on the fixed plate. 1. On one lower side, the control motor 2 is on the upper side wall of the fixed plate 1. The threaded rod 12 passes through the support box 5 and the fixed plate 1 and is connected to the output end of the control motor 2. The telescopic rod 6 is on the threaded rod 12. The threaded rod 12 passes through the telescopic rod 6 and is threadedly connected to it. The telescopic rod 6 fits against and is slidably connected to the inner side wall of the support box 5. The bottom wall of the support box 5 is provided with an opening that is adapted to the telescopic rod 6. The stop block 13 is on the upper end of the telescopic rod 6 and is adapted to the support box 5. The aerator has a built-in remote control system.

[0030] During use, the fixing plate 1 of the device is initially erected on the edge of the pool or other supporting structure to ensure the overall stability of the equipment. The distance between the fixing plate 1 and the pool edge is adjusted using the distance adjustment component and then fixed. The control motor 2 is started through the remote control system. The control motor 2 drives the threaded rod 12 to rotate. Since the telescopic rod 6 and the threaded rod 12 are connected by threads, and the telescopic rod 6 is restricted by the sliding constraint of the inner wall of the support box 5, the rotation of the threaded rod 12 is converted into the vertical lifting and lowering motion of the telescopic rod 6. When the telescopic rod 6 rises or falls to the target height, the control motor 2 is locked. At the same time, the stop block 13 and the support box 5 also form a physical limit to prevent the telescopic rod 6 from falling off. The gap between the opening and the telescopic rod 6 is filled with a rubber sealing ring to ensure that water vapor cannot enter the support box 5 during the lifting process. Then, the rotating motor 11 is started, and its output end drives the rotating shaft 9 to rotate at high speed, which drives the lower parabolic blade 10 to rotate around the axis. The parabolic cross-section design of the blade 10 makes the water flow form an alternating shear of laminar and turbulent flow on the surface of the blade 10, which efficiently cuts the air into microbubbles and generates an upward lifting force, expanding the gas-liquid contact area. During the aeration process, the immersion depth of the blade 10 can be adjusted in real time through the telescopic component. For example, the blade 10 can be raised to avoid idling when the water level is low, and lowered when the water level is high to enhance the disturbance range.

[0031] In practical use, it needs to be able to adapt to irregular installation scenarios at the edge of the pool. To meet the above requirements, in this embodiment, the distance adjustment component includes an extension plate 3, a damping slide 14, and a damping slider 15. A groove is provided on one side of the fixing plate 1, and the damping slide 14 is symmetrically arranged on both sides of the groove and fixedly connected thereto. The damping slider 15 passes through the damping slide 14 and is damped and slidably connected thereto. The extension plate 3 is located between the two damping sliders 15, and a matching fixing screw 4 is provided at one end of the extension plate 3.

[0032] Manually pull the extension plate 3 to drive the damping slider 15 to slide laterally along the damping slide 14. The sliding resistance of the damping slider 15 can prevent accidental displacement caused by water flow impact and assist in precise positioning. After adjusting according to the actual width of the pool, tighten the fixing screws 4 to fix the relative position of the extension plate 3 and the fixing plate 1 to form a stable lateral support structure.

[0033] In actual use, it is necessary to isolate moisture and impurities from intrusion and significantly reduce the risk of motor corrosion. In order to meet the above requirements, in this embodiment, the protective box assembly includes a waterproof box 7 and a sealing plate 8. The waterproof box 7 is provided with a cavity, the rotating motor 11 is in the cavity, and the sealing plate 8 is on the positive side wall of the cavity and is sealed to it.

[0034] In practical use, it is necessary to optimize fluid shear force and enhance wear resistance and corrosion resistance. In order to meet the above requirements, in this embodiment, the blade 10 is made of titanium alloy, its cross section is parabolic, and its surface is coated with titanium nitride by plasma spraying.

[0035] In actual use, it is necessary to accelerate the dissipation of heat from the motor to prevent high temperature from causing seal aging or motor performance degradation. In order to meet the above requirements, in this embodiment, the inner wall of the waterproof box 7 is provided with multiple sets of heat dissipation fins.

[0036] In practical use, it is necessary to improve the guiding accuracy and vibration resistance of the adjustment process to prevent accidental derailment. In order to meet the above requirements, in this embodiment, the cross-section of the damping slide 14 and the damping slider 15 is T-shaped.
