Description

Technical Field

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

[0002] In the process of sewage treatment and water treatment, the aerator is an important equipment used to increase the dissolved oxygen content in the water body and promote the degradation and oxidation of organic matter. The traditional aerator has a fixed structure and cannot be adjusted in height, which cannot adapt to different working environments and needs. Therefore, designing an aerator with adjustable height has important practical application value. Utility Model Content

[0003] The problem to be solved by the present application is that the existing cyclone aerator has a fixed structure and is not height-adjustable, and thus cannot be adapted and adjusted according to the actual aeration height.

[0004] In order to solve the above-mentioned technical problems, the present application provides an extended 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 arranged 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. A plurality of pull rod assemblies for applying circumferential positioning operations to the diverter and the cutter are arranged around the upper part of the base, and the pull rod assembly is an elastic and retractable structure that can perform adaptive contraction adjustment according to the height size of the aerator after increasing or decreasing the cutter.

[0005] Since the cyclone aerator of the present application is designed with a diverter, a cutter and a pull rod assembly, it is possible to achieve uniform distribution of gas through the diverter, sufficient mixing of gas and water through the cutter, and adaptive adaptation and fixing of the aerator height through the pull rod assembly, thereby solving the problem that the cyclone aerator of the prior art has a fixed structure and cannot be adjusted in height, thus being unable to be adapted and adjusted according to the actual aeration height.

[0017] 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

[0018] The present application relates to an extended cyclone aerator, such as Figure 1-10 As shown, the aerator includes a base 5 for serving as a basic support, and an air inlet pipe 4 is arranged above the base 5 and is detachably connected to the base 5 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 5 and is connected to the air inlet pipe 4 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 5 and can be easily increased or decreased. Therefore, a plurality of pull rod assemblies 3 for applying circumferential positioning operations to the diverter 2 and the cutter 1 are arranged around the upper part of the base 5. In order to be able to conveniently increase or decrease the cutter 1 without frequently replacing the pull rod assemblies 3 of different lengths, the pull rod assembly 3 is an elastically retractable structure, so that an adaptive elastic contraction adjustment operation can be performed according to the height size after the cutter 1 is increased or decreased.

[0019] Since the aerator is arranged vertically, in order to achieve effective air intake operation of the air intake pipe 4, the air intake pipe 4 is composed of two sections of pipe bodies that are arranged perpendicular to each other and connected.

[0020] In order to enable water to enter the aerator for circulation operation, a bottom pipe 11 is arranged on the top of the base 5, which is concentric with the air inlet pipe 4 and non-sealed, and a cavity is left between the bottom pipe 11 and the air inlet pipe 4 for water to flow.

[0021] The diverter 2 includes a first cylinder 9, a partition 8 and a core rod 10. The first cylinder 9 is a straight hollow structure. The interior of the first cylinder 9 is mirror-symmetrically arranged with a partition 8 that plays a guiding role. The core rod 10 is arranged concentrically with the diverter 2 at the circumferential center position. The side of the core rod 10 is connected to the partition 8, which can not only improve the impact strength of the partition 8, but also achieve uniform distribution of gas.

[0022] The cutter 1 includes a second cylinder 6 and a mushroom head 7. The second cylinder 6 is a straight hollow structure. A plurality of mushroom heads 7 for cutting the gas to improve the mixing efficiency are evenly arranged in the circumferential direction inside the second cylinder 6. The mushroom head 7 can use a single-stage mushroom head 7 or a bipolar mushroom head 7 according to the needs of use, or the cutters 1 equipped with a single-stage mushroom head 7 and a bipolar mushroom head 7 can be selected and stacked for use.

[0023] The pull rod assembly 3 includes a rod body 13, a nut 12, and a spring 14. The rod body 13 is evenly and socketedly arranged along the circumferential direction of the diverter 2 and the cutter 1. The end of the rod body 13 is provided with a nut 12 for realizing a locking and positioning operation. In order to be able to perform a height limiting and fixing operation on the aerator after adding or removing the cutter 1, the rod body 13 is divided into a two-section structure, and a socketed spring 14 is arranged between the rod bodies 13. The spring 14 is a tension spring with a pre-tightening tension force, so that the physical length of the rod body 13 can be adaptively changed with the increase or decrease of the cutter 1 by means of the elastic traction operation of the tension spring.

[0024] When in use, the aerator is immersed in the water body, and the gas enters the diverter 2 along the air inlet pipe 4, and then flows upward evenly and contacts the water body under the action of the partition 8 and the core rod 10 of the diverter 2. As the gas continues to rise, it will collide with the mushroom head 7 of the cutter 1, causing the gas to burst, thereby increasing the contact area with the water body, so that the gas can fully contact the water body, which can not only promote the oxidation and decomposition of organic matter in the water body, but also increase the dissolved oxygen content of the water body, which is beneficial to the subsequent growth and reproduction of microorganisms. The rod body 13 pulled by the spring 14 enables the pull rod assembly 3 to perform adaptive self-adjusting limit operation on the aerator whose physical height has changed after adding or removing the cutter 1.

[0025] It is to be understood that the present application is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present application. 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. Therefore, the present application is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of the present application are within the scope protected by the present application.
