Description

Technical Field

[0001] This utility model relates to the technical field of tubular aerators, specifically a novel tubular aerator. Background Technology

[0002] Aeration is a crucial process in aerobic biological wastewater treatment systems. Its main purpose is to provide the oxygen needed for microbial metabolism and to act as a mixer, allowing microorganisms to come into full contact with dissolved oxygen and suspended organic matter in the water, thus promoting the microbial degradation of organic matter. It also disperses dissolved gases or volatile substances in the water into the atmosphere.

[0003] An investigation revealed that a Chinese utility model patent discloses a tubular aerator (publication number: CN222834124U), which includes a conduit. The main body of the conduit has a bidirectional through-structure on both the left and right sides, and a flange is fixedly connected to the outer side of the conduit. The main body of the flange has an annular structure, and the diameter of the flange is larger than the diameter of the conduit. There are two flanges, which are fixedly connected to the left and right sides of the conduit respectively. The conduit and the flange together form a connection structure, and a motor is installed at the front end of the outer periphery of the conduit. There are two motors.

[0004] In the aforementioned patent, the height of the aeration pipe is quickly adjusted by moving the sleeve up and down along the guide groove opened in the connecting pipe. This allows the aerated water to be stirred during use, enabling the oxygen in the aeration pipe to mix with the water more quickly. However, the aeration pipe can only move vertically along the guide groove and cannot rotate. Therefore, the bubbles will rise along a fixed vertical or near-vertical path, only promoting the flow of water in a limited area directly above and in the vicinity. Water far from this fixed path is difficult to be effectively stirred, which may reduce the aeration efficiency.

[0005] Therefore, this utility model provides a novel tubular aerator to solve the above problems. Utility Model Content

[0007] This invention provides a novel tubular aerator, which aims to solve the problems mentioned in the background art.

[0008] (II) Technical Solution

[0009] To achieve the above objectives, the present invention provides the following technical solution: a novel tubular aerator, comprising a guide tube, a fixed cylinder fixedly mounted on the guide tube, an aeration pipe disposed above the fixed cylinder, an aeration hole opened on the side surface of the aeration pipe, and a rotating mechanism disposed inside the fixed cylinder for controlling the rotation of the aeration pipe.

[0010] The rotating mechanism includes a sleeve slidably installed inside the fixed cylinder, a connecting cylinder slidably installed inside the sleeve, a guide rail formed on the inner wall of the sleeve, a protrusion fixedly installed on the side surface of the connecting cylinder, a spring disposed inside the fixed cylinder, and a fixed column fixedly installed inside the conduit.

[0011] As a preferred technical solution of this application, multiple aeration holes are provided, and the aeration holes are evenly distributed on the side surface of the aeration pipe. The protrusion is slidably installed inside the guide rail. The spring is sleeved on the side surface of the fixing post. One end of the spring is fixedly connected to the inner wall of the guide tube, and the other end of the spring is fixedly connected to the bottom of the sleeve.

[0014] As a preferred technical solution of this application, the end of the rotating shaft away from the motor passes through the conduit and is fixedly connected to a half gear, and a connecting frame is provided on one side of the conduit.

[0016] (III) Beneficial Effects

[0017] 1. This utility model has a simple structure and is easy to use. Through the setting of the rotating mechanism, the sleeve rises and falls inside the cylinder, compressing the spring and causing the connecting cylinder to descend synchronously. The top of the connecting cylinder is connected to the aeration pipe, thereby driving the aeration pipe to descend. When the bottom of the connecting cylinder touches the fixed column, the sleeve continues to descend, and the protrusion moves along the guide rail, causing the connecting cylinder to rotate 90 degrees. The aeration pipe also rotates 90 degrees. During the rising and falling of the aeration pipe, the rotation function can be realized, thereby achieving the effect of all-round aeration, ensuring uniform aeration of the aerator, and effectively improving the aeration efficiency.

[0018] 2. This utility model has a simple structure and is easy to use. With the arrangement of half gear, rack, connecting frame and connecting plate, when the shaft rotates, due to the meshing mechanism of half gear and rack, rack will move vertically along the side wall of the guide tube. This movement of rack will drive the connecting frame to rise and fall. Through the action of connecting plate, the sleeve will move up and down accordingly, realizing automatic control of the raising and lowering of the aeration pipe. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides a novel tubular aerator, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the novel tubular aerator includes a conduit 1, a fixed cylinder 2 fixedly installed on the conduit 1, an aeration pipe 5 disposed above the fixed cylinder 2, an aeration hole 6 opened on the side surface of the aeration pipe 5, and a rotating mechanism disposed inside the fixed cylinder 2 for controlling the rotation of the aeration pipe 5.

[0028] The rotating mechanism includes a sleeve 3 that is slidably installed inside the fixed cylinder 2, a connecting cylinder 4 that is slidably installed inside the sleeve 3, a guide rail 7 that is opened on the inner wall of the sleeve 3, a protrusion 8 that is fixedly installed on the side surface of the connecting cylinder 4, a spring 9 that is disposed inside the fixed cylinder 2, and a fixed column 10 that is fixedly installed inside the guide tube 1.

[0029] Multiple aeration holes 6 are provided, and the aeration holes 6 are evenly distributed on the side surface of the aeration pipe 5. The protrusion 8 is slidably installed inside the guide rail 7. The spring 9 is sleeved on the side surface of the fixing post 10. One end of the spring 9 is fixedly connected to the inner wall of the guide tube 1, and the other end of the spring 9 is fixedly connected to the bottom of the sleeve 3. The fixing post 10 is located directly below the connecting cylinder 4.

[0030] In use, this novel tubular aerator connects the guide tube 1 to an external aerator via a flange fixed to its outer side. The guide tube 1 is then simultaneously placed inside the water tank. The external aerator is then activated to supply air into the guide tube 1. During air supply, the gas passes through the fixed cylinder 2, sleeve 3, and connecting cylinder 4 into the aeration pipe 5. Once inside the aeration pipe 5, oxygen is rapidly introduced into the water through the aeration holes 6 on its outer surface, achieving aeration and water purification. During aeration, the sleeve 3 is positioned within the fixed cylinder 2... The internal lifting mechanism, via the compression spring 9, causes the connecting cylinder 4, which is movably connected inside the sleeve 3, to descend synchronously. The top of the connecting cylinder 4 is fixedly connected to the aeration pipe 5, thus causing the aeration pipe 5 to descend synchronously. After the bottom of the connecting cylinder 4 contacts the fixed column 10, the sleeve 3 continues to descend, causing the protrusion 8 to move along the guide rail 7. This causes the connecting cylinder 4 to rotate 90 degrees inside the sleeve 3, thereby causing the aeration pipe 5 to rotate 90 degrees, changing the orientation of the aeration holes 6, and achieving all-around aeration operation, thus improving the aeration effect. The return force of the spring 9 causes the sleeve 3 to reset the connecting cylinder 4 and the aeration pipe 5 for easy reuse next time.

[0031] Furthermore, in order to accelerate the entry of oxygen into the aeration pipe 5, such as... Figure 1 , Figure 2 and Figure 3 As shown, a motor 11 is fixedly connected to the side surface of the conduit 1, and a rotating shaft 12 is rotatably connected inside the conduit 1. The output end of the motor 11 passes through the conduit 1 and is fixedly connected to one end of the rotating shaft 12.

[0032] A guide plate 13 is fixedly connected to the side surface of the rotating shaft 12. Multiple guide plates 13 are provided and are arranged in a ring array on the rotating shaft 12.

[0033] When this new type of tubular aerator is in use, the motor 11 starts, driving the rotating shaft 12 to rotate inside the guide tube 1, which in turn drives the guide plate 13 to rotate synchronously. Through the rotation of the guide plate 13, the oxygen entering the guide tube 1 is guided, so that the oxygen enters the aeration tube 5 along the surface of the guide plate 13, which speeds up the speed at which oxygen enters the aeration tube 5, thereby improving the aeration efficiency and thus improving the water purification effect. At the same time, multiple guide plates 13 are provided and distributed in a ring array on the rotating shaft 12, so that the oxygen can be more evenly dispersed into the aeration tube 5, further improving the aeration effect.

[0034] It should be noted that, in order to control the raising and lowering of sleeve 3, such as Figure 1 , Figure 2 and Figure 3As shown, the end of the rotating shaft 12 away from the motor 11 passes through the conduit 1 and is fixedly connected to the half gear 14. A connecting bracket 15 is provided on one side of the conduit 1.

[0035] A rack 16 is fixedly connected to the bottom of the connecting frame 15, and the rack 16 meshes with the half gear 14. A connecting plate 17 is fixedly connected to the top of the connecting frame 15, and one side of the connecting plate 17 is fixedly connected to one side of the sleeve 3.

[0036] When the new tubular aerator is in use, when the rotating shaft 12 rotates, the rack 16 will move up and down along the side wall of the guide tube 1 due to the meshing relationship between the half gear 14 and the rack 16. The movement of the rack 16 drives the connecting frame 15 to rise and fall, and then drives the sleeve 3 to perform corresponding rising and falling movements through the connecting plate 17.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
