Description

Technical Field

[0001] This utility model belongs to the field of aerator technology and relates to a vortex aerator that is easy to disassemble and install. Background Technology

[0002] A vortex aerator is a mechanical device used in wastewater treatment, water oxygenation, and mixing processes. Its core principle is to generate a vortex effect through its mechanical structure, efficiently dissolving air into water to achieve water quality improvement or treatment goals. The vortex aerator utilizes rotating components (such as impellers and turntables) moving at high speed in the water to create a negative pressure zone or shear force, drawing in air and breaking it into tiny bubbles. These bubbles come into full contact with the water as they rise, dissolving oxygen and simultaneously promoting water mixing and mass transfer.

[0003] The installation of existing vortex aerators requires aligning the mounting plate with the screw holes at the desired installation location before tightening the bolts. This process demands high concentration and meticulous operation, requiring operators to repeatedly adjust the aerator's position until all screw holes are accurately aligned. This undoubtedly increases installation time. Furthermore, during manual alignment, even slight errors can lead to inaccurate alignment of the mounting plate and screw holes. Such inaccuracies may prevent bolts from being screwed in smoothly, or result in looseness or shaking of the equipment after tightening. Uneven fluid turbulence in traditional aerators also affects oxygen transfer efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a vortex aerator that is easy to disassemble and install.

[0005] This utility model discloses a vortex aerator that is easy to disassemble and install, including a mounting base. The mounting base has a mounting groove, and a mounting plate is installed in the mounting groove. A mounting bracket is installed on the mounting plate. The mounting plate has symmetrical positioning grooves on both sides of the mounting groove. Positioning blocks are symmetrically installed on both sides of the mounting plate and are inserted into the positioning grooves. One of the positioning blocks has a telescopic cavity with a snap-fit ​​component inside. The mounting plate has a sliding cavity on the side near the snap-fit ​​component with a lifting component inside. The mounting plate has four symmetrical bolt grooves with fixing bolts installed in them. The mounting plate also has multiple symmetrical mounting holes.

[0006] The snap-fit ​​component includes four spring telescopic posts, which are installed in the telescopic cavity provided by the positioning block, and one end of each of the four spring telescopic posts is attached to the same snap-fit ​​block.

[0007] The lifting component includes a sliding rod, which is slidably connected to a sliding cavity provided in the mounting plate. A return spring is sleeved on the sliding rod and is disposed in the sliding cavity. The two ends of the return spring are respectively connected to the sliding rod and the sliding cavity. A lifting plate is installed on the end of the sliding rod near the locking block.

[0008] The mounting bracket has a fixed housing and a servo motor mounted on its top two sides respectively. A drive shaft is rotatably connected to the fixed housing. The drive shaft is rotatably connected to the top of the mounting bracket, and one end of the drive shaft is connected to the output shaft of the servo motor.

[0009] A vortex impeller is installed at the end of the drive shaft away from the servo motor. A gear one is provided on the drive shaft, and a gear two is meshed on the gear one. A driven shaft is installed at the center of the gear two, and four turbulence components are provided on the driven shaft.

[0010] The turbulence assembly includes a mounting box and a first bevel gear. The mounting box is rotatably connected to a driven shaft. The first bevel gear is installed inside the driven shaft. A second bevel gear is meshed with the first bevel gear. A connecting shaft is installed on the second bevel gear. The connecting shaft is rotatably connected to the mounting box. A turbulence impeller is installed at the bottom of the connecting shaft. Multiple mounting boxes are mounted on the same fixed bracket. The fixed bracket is installed on a fixed outer shell.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by utilizing the physical guiding effect of the positioning block and the positioning groove, the mounting plate can be quickly and roughly positioned on the mounting base, avoiding the tedious manual alignment process and greatly shortening the preparation time before installation. The snap-fit ​​block automatically embeds into the recess of the positioning groove under the action of the spring telescopic column, realizing the temporary locking of the mounting plate. This step not only prevents the mounting plate from being accidentally displaced in subsequent operations, but also enables the installation position of the fixing bolts to be automatically aligned, further accelerating the installation speed. The entire installation process is simplified into a few intuitive and easy-to-execute steps, which can be quickly mastered even by inexperienced operators.

[0012] The turbulence-inducing component of this invention drives a first bevel gear inside the mounting box via a driven shaft, which in turn drives a turbulence impeller at the end of the connecting shaft to rotate, forming a multi-directional vortex. This vortex breaks the laminar flow state of the water, making the water more active and increasing the opportunity for gas-liquid contact. The presence of the multi-directional vortex increases the contact area between gas and liquid, allowing oxygen to dissolve more effectively into the water and improving aeration efficiency. Since the turbulence-inducing components are distributed on the driven shaft, and each component can independently generate a vortex, these vortices can be evenly distributed in the water, avoiding the problem of uneven aeration.

[0019] like Figures 1-5 As shown, a vortex aerator that is easy to disassemble and install includes a mounting base 1. The mounting base 1 has a mounting groove 4, and a mounting plate 3 is installed within the mounting groove 4. A mounting bracket 2 is installed on the mounting plate 3. The mounting plate 3 has symmetrically arranged positioning grooves 6 on both sides of the mounting groove 4. Positioning blocks 5 are symmetrically installed on both sides of the mounting plate 3, and the positioning blocks 5 are inserted into the positioning grooves 6. One of the positioning blocks 5 has a telescopic cavity containing a snap-fit ​​component. A sliding cavity is provided on the side of the mounting plate 3 near the snap-fit ​​component, containing a lifting component. The mounting plate 3 has four symmetrically arranged bolt grooves 7. The mounting plate 3 has multiple mounting holes 9 symmetrically arranged on it and is equipped with a fixing bolt 8. The snap-fit ​​component includes four spring telescopic columns 10, which are installed in the telescopic cavity of the positioning block 5. One end of each of the four spring telescopic columns 10 is equipped with the same snap-fit ​​block 11. The lifting component includes a sliding rod 12, which is slidably connected in the sliding cavity of the mounting plate 3. A return spring 13 is sleeved on the sliding rod 12 and is located in the sliding cavity. Both ends of the return spring 13 are connected to the sliding rod 12 and the sliding cavity, respectively. A lifting plate 14 is installed on the end of the sliding rod 12 near the snap-fit ​​block 11.

[0020] During operation, the mounting base 1 needs to be installed at the desired location for the aerator, and fixed in the mounting hole 9 with external bolts. To install the aerator, the positioning blocks 5 on both sides of the mounting plate 3 are inserted into the positioning groove 6 in the mounting groove 4 to form a physical guide for quick rough positioning. The operator can achieve initial alignment without fine adjustment, significantly shortening the installation time. When the positioning block 5 is inserted into the positioning groove 6, the snap-fit ​​block 11 is automatically embedded into the recess of the positioning groove 6 under the pressure of the spring telescopic column 10, achieving temporary locking and preventing the mounting plate 3 from shifting. Then, the mounting plate 3 is automatically positioned in relation to the four bolt grooves 7 on the mounting base 1. The fixing bolts 8 are then tightened, and the snap-fit ​​component initially fixes the mounting plate 3 to the mounting base 1, facilitating the installation of the fixing bolts 8 and preventing the aerator on the mounting plate 3 and mounting bracket 2 from moving during bolt installation, thereby reducing the installation complexity and achieving the effect of rapid installation.

[0021] If fine-tuning is required, pressing the lifting plate 14 will push the locking block 11 back via the sliding rod 12, releasing the lock and allowing the mounting plate 3 to slide slightly for precise alignment of the bolt holes. The return spring 13 ensures that the lifting plate 14 automatically returns to its original position after adjustment. Example

[0022] like Figures 2-4 As shown, a fixed housing 15 and a servo motor 16 are respectively mounted on the two sides of the top of the mounting bracket 2. A drive shaft 17 is rotatably connected to the fixed housing 15. The drive shaft 17 is rotatably connected to the top of the mounting bracket 2, and one end of the drive shaft 17 is connected to the output shaft of the servo motor 16. A vortex impeller 18 is mounted on the end of the drive shaft 17 away from the servo motor 16. A gear 19 is provided on the drive shaft 17, and a gear 20 is meshed on the gear 19. A driven shaft 21 is mounted at the center of the gear 20, and four turbulence components are provided on the driven shaft 21. The servo motor 16 drives the drive shaft 17 to rotate on the mounting bracket 2, and the drive shaft 17 drives the vortex impeller 18 to rotate, thus performing aeration. The turbulence components include a mounting box 26 and a first bevel gear 22. The mounting box 26 is rotatably connected to the driven shaft 21, and the first bevel gear 22... Installed inside the driven shaft 21, a second bevel gear 23 is meshed on the first bevel gear 22, and a connecting shaft 24 is installed on the second bevel gear 23. The connecting shaft 24 is rotatably connected to the mounting box 26, and a disturbance impeller 25 is installed at the bottom of the connecting shaft 24. Multiple mounting boxes 26 are equipped with the same fixed bracket 27, which is installed on the fixed outer shell 15. When the drive shaft 17 drives the vortex impeller 18 for aeration, the drive shaft 17 drives the first gear 19 and the second gear 20 to speed up the driven shaft 21. The driven shaft 21 drives the turbulence component connected to it to turbulence, and the driven shaft 21 drives the first bevel gear 22 inside the mounting box 26 to drive the second bevel gear 23, which drives the disturbance impeller 25 at the end of the connecting shaft 24 to rotate, forming a multi-directional vortex, breaking the laminar flow of water, increasing the gas-liquid contact area, and increasing the aeration effect.

[0023] The turbulence-generating components drive the first bevel gear 22 within the mounting box 26 via the driven shaft 21, which in turn drives the turbulence impeller 25 at the end of the connecting shaft 24 to rotate, forming a multi-directional vortex. This vortex breaks the laminar flow state of the water, making the water more active and increasing the chance of gas-liquid contact. The presence of the multi-directional vortex increases the contact area between gas and liquid, allowing oxygen to dissolve more effectively into the water and improving aeration efficiency. Since the turbulence-generating components are distributed on the driven shaft 21, and each component can generate vortices independently, these vortices can be evenly distributed in the water, avoiding the problem of uneven aeration.
