Description

Technical Field

[0001] This utility model belongs to the field of aerator technology, and in particular relates to a multi-stage water-cutting vortex aerator. Background Technology

[0002] The water-cutting cyclone aerator is a new type of aeration device mainly used in the field of water treatment, especially in sewage treatment, aquaculture water oxygenation, and oil flotation in chemical ponds. Its working principle is to mix water and gas through high-speed centrifugal force, forming microbubbles, thereby enhancing the adsorption and oxidation of pollutants in the water. Traditional aerators, to increase oxygen content, use fan blades to disperse the intake mixture, thus increasing the adsorption of the mixture and gas. However, sewage or sludge may contain large and hard stones or other foreign objects. When these impurities enter the aeration chamber, they may collide with the fan blades or the internal cyclone column if not blocked. Prolonged use can cause the fan blades to wear down or the cyclone to be damaged, thus affecting the aeration effect and service life of the equipment. For example, a technical solution disclosed in patent number CN202322347009.7 suffers from the above-mentioned problem, where large impurities can easily damage the fan blades and cyclone. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a multi-stage water-cutting vortex aerator, which solves the problem that large impurities can easily damage the internal parts of the equipment during use.

[0004] This utility model is implemented as follows: a multi-stage water-cutting vortex aerator includes an aeration shell, a vortex column rotatably disposed within the aeration shell, an air pipe penetrating the aeration shell, fan blades fixedly disposed on the lower side of the vortex column, and a protective plate fixedly disposed within the aeration shell, and further includes:

[0005] The filter assembly, located inside the protective plate, is used to filter large impurities. It includes a drive shaft that rotates inside the protective plate and multiple protective meshes mounted on the drive shaft.

[0006] A cleaning component, installed on the protective plate, is used for cleaning when the protective net rotates, including several cleaning plates that are rotated on the protective plate;

[0007] The connecting component is installed inside the aeration shell, and when the fan blades rotate, it drives the protective net to rotate.

[0008] In a preferred embodiment of this invention, there are two protective plates, and the protective net is rotatably disposed between the two protective plates. The protective plates are provided with multiple fan-shaped flow grooves.

[0009] As a preferred embodiment of this utility model, the cleaning component includes a storage groove formed on the lower side of the protective plate, the cleaning plate being rotatably disposed in the storage groove, the cleaning plate being arc-shaped, and torsion springs being sleeved on both sides of the cleaning plate.

[0010] As a preferred embodiment of this utility model, the connecting component includes a gearbox installed inside the aeration shell. The input end of the gearbox is connected to the fan blades via a drive, and the output end of the gearbox is provided with a half gear. A rotating column is rotatably arranged inside the aeration shell. The rotating column is connected to the drive shaft via a drive, and a full gear that meshes with the half gear is provided on the rotating column.

[0011] As a preferred embodiment of this invention, the transmission method of the gearbox and fan blades is chain drive, and the transmission method of the rotating column and drive shaft is also chain drive.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] This invention effectively filters the fluid entering the aeration shell by installing a protective net at the bottom of the aeration shell. This prevents large or sharp objects in the sludge from entering the aeration shell and damaging the fan blades and vortex column inside. During aeration, the fan blades drive the connecting assembly, which in turn drives the protective net to rotate. Combined with the cleaning assembly, this effectively ensures the permeability of the protective net, preventing clogging, while also filtering out large impurities. This further guarantees the effectiveness of the equipment and extends its service life. Attached Figure Description

[0020] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.

[0021] The structure of this utility model will now be described in detail with reference to the accompanying drawings.

[0022] like Figures 1 to 4 As shown in the figure, the multi-stage water-cutting vortex aerator provided in this embodiment includes an aeration shell 1, a vortex column 2 rotatably disposed within the aeration shell 1, an air pipe 3 penetrating the aeration shell 1, a fan blade 4 fixedly disposed on the lower side of the vortex column 2, and a protective plate 5 fixedly disposed within the aeration shell 1, and further includes:

[0023] The filter assembly, located inside the protective plate 5, is used to filter large impurities. It includes a drive shaft 12 that is rotated inside the protective plate 5, and multiple protective nets 6 mounted on the drive shaft 12.

[0024] A cleaning component, set on the protective plate 5, is used for cleaning when the protective net 6 rotates, including several cleaning plates 7 that are rotatably set on the protective plate 5;

[0025] The connecting component is installed inside the aeration shell 1, and when the fan blade 4 rotates, it drives the protective net 6 to rotate.

[0026] As a preferred embodiment of this utility model, there are two protective plates 5, and the protective net 6 is rotatably disposed between the two protective plates 5. Multiple fan-shaped flow grooves 15 are provided on the protective plates 5 to protect the protective net 6. At the same time, liquid and gas flow out from the flow grooves 15, thereby ensuring that the protective net 6 can complete the filtration of liquid entering the aeration shell 1, and preventing large hard objects from entering the aeration shell 1 and causing damage to the fan blades 4 and its internal parts.

[0027] As a preferred embodiment of this utility model, the cleaning component includes a storage groove 14 formed on the lower side of the protective plate 5, and a cleaning plate 7 is rotatably disposed in the storage groove 14. The cleaning plate 7 is arc-shaped, and torsion springs 13 are sleeved on both sides of the cleaning plate 7 to increase the torque of the cleaning plate 7, so that the cleaning plate 7 can effectively adhere to the protective net 6. This enables the cleaning plate 7 to clean the protective net 6 when it rotates, preventing the protective net 6 from becoming clogged, and at the same time preventing large-volume impurities from entering the aeration shell 1.

[0028] As a preferred embodiment of this utility model, the connecting component includes a gearbox 8 installed inside the aeration shell 1. The input end of the gearbox 8 is connected to the fan blade 4 via a transmission. A half gear 9 is provided at the output end of the gearbox 8. A rotating column 10 is rotatably arranged inside the aeration shell 1. The rotating column 10 is connected to the drive shaft 12 via a transmission, and a full gear 11 that meshes with the half gear 9 is provided on the rotating column 10 to drive the protective net 6 to rotate. This achieves the protection of the inside of the equipment during the aeration process while ensuring its permeability during use.

[0029] As a preferred embodiment of this utility model, the transmission method of the gearbox 8 and the fan blade 4 is chain drive, and the transmission method of the rotating column 10 and the drive shaft 12 is also chain drive, which effectively increases the transmission power of the equipment, while increasing the wear resistance and corrosion resistance of the equipment, and avoiding the situation of transmission pulleys.

[0030] The working principle of this utility model:

[0031] refer to Figure 1 and Figure 3 The airflow is injected through the air pipe 3, and at the same time, the gas generates negative pressure in the aeration shell 1, which drives the vortex column 2 to rotate. At this time, the mud and liquid rush in from the bottom of the aeration shell 1 and are discharged from the top of the aeration shell 1. The mud that enters the aeration shell 1 is dispersed by the rotating fan blades 4, thereby increasing the oxygen enrichment of the gas.

[0032] refer to Figure 3 When the sludge mixture and liquid enter the aeration shell 1, the swirl column 2 drives the fan blade 4 to rotate. At this time, the fan blade 4 disperses the sludge and other impurities in the mixture. Simultaneously, the fan blade 4 drives the input end of the gearbox 8, causing the output end of the gearbox 8 to drive the half gear 9 to rotate. When the half gear 9 rotates in the forward direction, the toothed position on the half gear 9 drives the full gear 11 to rotate, thus forming an intermittent drive for the full gear 11 to rotate. When the full gear 11 rotates, the full gear 11 drives the drive shaft 12 to rotate through the rotating column 10, which in turn causes the protective net 6 to rotate inside the protective plate 5. The protective net 6 can effectively filter large objects and prevent them from entering the aeration shell 1 and damaging the fan blade 4 and swirl column 2 inside the aeration shell 1, further ensuring its service life.

[0033] refer to Figure 4 When the drive shaft 12 drives the fan blade 4 to rotate, the torque of the torsion spring 13 acts on the cleaning plate 7, causing the cleaning plate 7 to adhere to the surface of the protective net 6. At the same time, in conjunction with the rotation of the protective net 6, the protective net 6 can be thoroughly cleaned, ensuring the permeability of the protective net 6 and avoiding blockage during its use. At the same time, it also protects the objects inside the aeration shell 1.

[0034] This invention effectively filters the fluid entering the aeration shell 1 by setting a protective net 6 at the bottom of the aeration shell 1. This prevents large or sharp objects in the sludge from entering the aeration shell 1 and damaging the fan blades 4 and vortex column 2 inside the aeration shell 1. During aeration, the fan blades 4 drive the connecting assembly, which in turn drives the protective net 6 to rotate. Combined with the cleaning assembly, this effectively ensures the permeability of the protective net 6, preventing clogging, while also filtering out large impurities. This further ensures the effectiveness of the equipment and extends its service life. The equipment is also simple in structure and highly practical.
