Description

Technical Field

[0001] The present application relates to the technical field of aerators, and in particular to a compensating cyclone aerator. Background Art

[0002] Aeration is a key process step in sewage treatment and aquatic organism breeding. It increases the dissolved oxygen content in the water by forcibly injecting air into the water to meet the needs of microbial metabolism or the survival of aquatic plants and animals. Existing aeration equipment usually includes a cutter, a diverter, and an air inlet pipe. However, due to temperature changes and / or mechanical vibrations, the air inlet pipe may undergo slight changes in length. If this change cannot be properly compensated, it may cause leakage or damage at the connection, affecting the aeration efficiency and the normal operation of the equipment. Utility Model Content

[0003] The problem to be solved by the present application is that the existing air inlet pipe for aerator may undergo a slight change in length due to temperature change and mechanical vibration, but cannot be properly compensated, resulting in the problem that the connection of the air inlet pipe is prone to leakage or damage.

[0004] In order to solve the above technical problems, the present application provides a compensating cyclone aerator, including a base for serving as a basic support, an air inlet pipe detachably connected to the base is arranged above the base, and a diverter connected to the air inlet pipe to achieve uniform gas distribution is also provided on the upper part of the base, and a cutter for generating fine bubbles and enhancing the oxygen dissolution efficiency is arranged above the diverter, and a plurality of pull plate assemblies for applying circumferential positioning operations to the diverter and the cutter are arranged around the upper part of the base, and a compensation assembly connected to the air inlet pipe and having an elastic compensation effect is arranged at the end of the air inlet pipe.

[0005] Since the aerator of the present application is designed with a pull plate assembly and a compensation assembly, the pull plate assembly can be used to achieve effective fixing operation between the diverter, cutter and the air inlet pipe, and the compensation assembly can be used to achieve deformation compensation operation when the length of the air inlet pipe changes, thereby solving the problem that the air inlet pipe of the aerator in the prior art will undergo slight changes in length due to temperature changes and mechanical vibrations, but cannot obtain proper compensation operation, causing the connection of the air inlet pipe to be prone to leakage or damage.

[0014] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application. Example

[0015] The present application relates to a compensating cyclone aerator, such as Figure 1-7 As shown, the aerator includes a base 6 for serving as a basic support, and an air inlet pipe 5 is arranged above the base 6 and is detachably connected to the base 6 for connecting to an external air source to introduce compressed air or other gases. A diverter 2 is also arranged on the upper part of the base 6 and is connected to the air inlet pipe 5 so as to evenly distribute the introduced gas. In order to enhance the sufficient mixing between the gas and the water body, a cutter 1 for generating fine bubbles and thus enhancing the oxygen dissolution efficiency is also arranged above the diverter 2. When the aerator is in use, the diverter 2 and the cutter 1 can be effectively fixed to the base 6 and can be easily increased or decreased. Therefore, a plurality of pull plate assemblies 3 for applying circumferential positioning operations to the diverter 2 and the cutter 1 are arranged around the upper part of the base 6. In order to achieve a micro-compensation effect on the air inlet pipe 5, a compensation assembly 4 connected to the air inlet pipe 5 and having an elastic compensation effect is arranged at the end of the air inlet pipe 5.

[0016] Since the aerator is arranged vertically, in order to achieve effective air intake operation of the air intake pipe 5, the air intake pipe 5 is composed of two sections of pipe bodies that are arranged perpendicular to each other and connected.

[0017] The diverter 2 includes a diverter tube 9, a partition 10 and a core rod 11. The diverter tube 9 is a straight hollow structure. The partition 10 for guiding the flow is arranged in a mirror-symmetrical manner inside the diverter tube 9. The core rod 11 arranged concentrically with the diverter 2 is arranged at the axial center position of the diverter 2. The side of the core rod 11 is connected to the partition 10, thereby improving the impact resistance of the partition 10 and achieving uniform distribution of the gas.

[0018] The cutter 1 comprises a cutting barrel 7 and a mushroom head 8. The cutting barrel 7 is a straight hollow structure. A plurality of mushroom heads 8 are evenly arranged in the circumferential direction inside the cutting barrel 7 for cutting the gas to improve the mixing efficiency.

[0019] The pull plate assembly 3 includes a vertical plate 12 and a horizontal plate 13. The vertical plates 12 are symmetrically arranged along the vertical direction of the aerator. The inner side walls of the vertical plates 12 are respectively abutted against the diversion cylinder 9 and the cutting cylinder 7, and the bottom side walls of the vertical plates 12 are abutted against the air inlet pipe 5. In order to effectively fix the vertical plates 12, a horizontal plate 13 that is clamped with the vertical plates 12 is also arranged on the upper part of the air inlet pipe 5, so that the fixing operation of the vertical plates 12 is achieved with the help of the horizontal plate 13.

[0020] The compensation component 4 includes an end pipe 14, a bellows 15 and a limit piece. The bellows 15 is arranged on one side of the intake pipe 5 and coaxially therewith. End pipes 14 for connecting are arranged on both sides of the bellows 15, so that a micro-compensation operation of the intake pipe 5 is achieved through the physical deformation of the bellows 15. A limit piece for protecting and limiting the deformation angle and deformation amount of the bellows 15 is arranged on the upper part of the end pipe 14.

[0021] The limiting member includes a block 16, a slide plate 17, and a bolt 18. The block 16 is symmetrically arranged on the upper side wall of the end tube 14 for guiding. The inside of the block 16 is provided with a slide plate 17 that can slide back and forth along its vertical direction. The slide plates 17 are connected by rivets 20. The upper part of the block 16 is also provided with a bolt 18 for limiting the slide plate 17. The upper part of the slide plate 17 is sequentially provided with a slide groove 19 adapted to the bolt 18 and the rivet 20. When the bellows 15 is extended and deformed, the two end tubes 14 will generate a relative back-to-back movement. When the bellows 15 is bent, the two end tubes 14 will generate an inward / outward bending movement, and the slide plate 17 can slide in the slide groove 19 with the help of the connected rivets 20 to complete the bending compensation operation, thereby avoiding leakage or damage of the intake pipe 5 due to temperature changes and / or mechanical vibrations.

[0022] When in use, the aerator is immersed in the water body, and the gas enters the inside of the diverter 2 along the air inlet pipe 5, and then under the action of the partition 10 and the core rod 11 of the diverter 2, it flows upward evenly and comes into contact with the water body. As the gas continues to rise, it will collide with the mushroom head 8 of the cutter 1, causing the gas to burst, thereby increasing the contact area with the water body, so that the gas can fully come into contact with the water body, thereby promoting the oxidation and decomposition of organic matter in the water body, and increasing the dissolved oxygen content of the water body, which is beneficial to the subsequent growth and reproduction of microorganisms. Thanks to the arrangement of the compensation component 4, the air inlet pipe 5 can obtain the elastic compensation of the bellows 15 in time after a slight change in length occurs, and with the help of the limiting operation of the limiting member, the bellows 15 can perform effective compensation operations within the compensation range, thereby avoiding leakage or damage of the air inlet pipe 5.

In addition, under the guidance of the present application, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present application.
