Abstract
Description
Technical Field
[0001] This utility model relates to the field of aerator technology, specifically a swirl aerator. Background Technology
[0002] Aerators are essential equipment for aeration and oxygenation in water supply and drainage. According to the method of use, they can be divided into surface aerators and underwater aerators. Underwater aerators mainly include microporous aerators, jet aerators, and swirl aerators. They are commonly used for aeration in sewage treatment and other fields. They consist of aerators, aeration ports, swirl chambers, swirl blades, sewage outlets, air inlet pipes, flanges, and air intake systems.
[0003] The aforementioned and existing related technologies often have the following drawbacks: After air is introduced into the aerator, it forms a vortex through its internal vortex chamber and vortex blades to contact the water. Although the aeration port is in an air-exhausting state for a long time, making it difficult for water sources to approach, the different application areas determine the usage time of the aerator. Therefore, when the aerator is not in use, the water source will directly enter the aerator through the aeration port. In some sewage treatment plants, there are many impurities in the bottom water source, which mix into the aerator and cause blockage of the vortex chamber. Although some aerators have a shielding mechanism, most of them are motor-driven and cannot automatically shield to prevent backflow of water after the machine is stopped.
[0004] Therefore, we propose a swirl aerator. Utility Model Content
[0005] The purpose of this invention is to provide a swirl aerator to solve the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a vortex aerator, comprising an aerator, wherein an aeration port is provided on the inner wall of the aerator, and vortex blades are installed on the inner wall of the aeration port. A sewage outlet is provided on the lower surface of the aerator, and an air inlet pipe is connected to the arc surface of the aerator.

A support plate is fixedly connected to the lower surface of the fixed frame, and the inner wall of the support plate abuts against the rotating frame. A baffle is fixedly connected to the side of the rotating frame near the aerator, and the baffle is located above the aeration port.
[0007] The aforementioned components achieve the effect of automatically blocking the aeration port of the swirl aerator, thereby minimizing the problem of sewage backflow into the swirl chamber and causing blockage when the aerator stops, as the drive device is unable to block the aeration port.
[0008] Preferably, a filling block is fixedly connected to the side of the baffle near the aerator, and the filling block is an arc-shaped block.
[0009] The effect achieved by the above components is that the baffle drives the filling block to fit against the inner wall of the aeration port, and the filling block of the arc-shaped block fills the gap between the baffle and the aeration port.
[0010] Preferably, a sealing ring, which is a rubber ring, is fixedly connected to the side of the baffle near the filling block.
[0011] The effect achieved by the above components is that the baffle moves the sealing ring to fit on the arc surface of the aerator, thereby improving the sealing performance between the baffle and the aerator.
[0012] Preferably, an inclined plate is fixedly connected to the side of the baffle near the rotating frame, and the higher part of the inclined plate is located at the connection point of the rotating frame.
[0013] The effect achieved by the above components is that the water flow impacts the inclined plate, causing the baffle to rotate, and the inclined plate plays a role in improving the success rate of the baffle closing.
[0014] Preferably, the arc surface of the air intake pipe is provided with a support structure, the support structure includes a connecting rope, one end of the connecting rope is fixedly connected to the air intake pipe, the other end of the connecting rope is fixedly connected to a U-shaped plate, one side of the U-shaped plate is fixedly connected to a long rod, and the arc surface of the long rod is slidably connected to the inner wall of the flange.
[0015] The aforementioned components achieve the following effect: they support the flange, allowing the air intake system flange to be supported and limited during the initial installation and maintenance of the aerator, thereby facilitating installation by personnel and improving overall maintenance efficiency.
[0016] Preferably, a positioning rod is fixedly connected to one side of the U-shaped plate relative to the long rod, and the length of the positioning rod is less than the length of the long rod itself.
[0017] The effect achieved by the above components is that after the long rod is inserted a certain distance into the flange hole, the positioning rod is inserted, and the positioning rod plays the role of positioning the flange to rotate.
[0018] Preferably, a round rod is fixedly connected to the lower surface of the U-shaped plate, and the connecting rope is an elastic rope.
[0019] The effect achieved by the above components is to better place the U-shaped board by using the connecting rope, which is an elastic cord.
[0020] Compared with the prior art, the beneficial effects of this utility model are:
[0021] 1. This utility model achieves the effect of automatically blocking the aeration port of the swirl aerator by setting a shielding structure. The internal flow field characteristics of the swirl aerator, combined with the mechanical structure and airflow, reduce the use of electric drive.

Detailed Implementation
[0028] 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.
[0029] Please see Figure 1 and Figure 2This utility model provides a technical solution: a vortex aerator, including an aerator 1, an aeration port 2 on the inner wall of the aerator 1, vortex blades 3 installed on the inner wall of the aeration port 2, a sewage outlet 4 on the lower surface of the aerator 1, an air inlet pipe 5 connected to the arc surface of the aerator 1, a flange 6 fixedly connected to the arc surface of the air inlet pipe 5, and a shielding structure 7 on the arc surface of the aerator 1, which achieves the effect of automatically shielding the aeration port 2 of the vortex aerator 1, thereby minimizing the problem of sewage backflow into the vortex chamber and blockage caused by the inability of the drive device to shield when the aerator 1 stops. A support structure 8 on the arc surface of the air inlet pipe 5 achieves the effect of supporting the flange 6, so that the flange 6 of the air inlet system can be supported and limited during the initial installation of the aerator 1, thereby further facilitating personnel installation and improving overall maintenance efficiency.
[0030] The specific setup and function of its shielding structure 7 and supporting structure 8 will be explained below.
[0031] like Figure 2 and Figure 3 As shown, the shielding structure 7 includes a fixed frame 71. One side of the fixed frame 71 is fixedly connected to the aerator 1, and the other side of the fixed frame 71 is rotatably connected to a rotating frame 72. A support plate 73 is fixedly connected to the lower surface of the fixed frame 71. The inner wall of the support plate 73 abuts against the rotating frame 72. A baffle 74 is fixedly connected to the side of the rotating frame 72 near the aerator 1. The baffle 74 is located above the aeration port 2. A filling block 75 is fixedly connected to the side of the baffle 74 near the aerator 1. The filling block 75 is an arc-shaped block. The baffle 74 drives the filling block 75 to fit against the inner wall of the aeration port 2. The arc-shaped filling block 75 fills the gap between the baffle 74 and the aeration port 2.
[0032] A sealing ring 76 is fixedly connected to the side of the baffle 74 near the filling block 75. The sealing ring 76 is a rubber ring. The baffle 74 drives the sealing ring 76 to fit onto the arc surface of the aerator 1. The sealing ring 76 achieves the effect of improving the sealing between the baffle 74 and the aerator 1. An inclined plate 77 is fixedly connected to the side of the baffle 74 near the rotating frame 72. The high point of the inclined plate 77 is located at the connection of the rotating frame 72. The water flow impacts the inclined plate 77, causing the baffle 74 to rotate. The inclined plate 77 plays the role of improving the success rate of the baffle 74 closing.
[0033] like Figure 2 and Figure 4As shown, the support structure 8 includes a connecting rope 81. One end of the connecting rope 81 is fixedly connected to the air intake pipe 5, and the other end of the connecting rope 81 is fixedly connected to a U-shaped plate 82. A long rod 83 is fixedly connected to one side of the U-shaped plate 82. The arc surface of the long rod 83 is slidably connected to the inner wall of the flange 6. A positioning rod 84 is fixedly connected to the U-shaped plate 82 relative to the side of the long rod 83. The length of the positioning rod 84 is less than the length of the long rod 83 itself. After the long rod 83 is inserted into the hole of the flange 6 for a certain distance, the positioning rod 84 is inserted. The positioning rod 84 plays the role of positioning the flange 6 to rotate. A round rod 85 is fixedly connected to the lower surface of the U-shaped plate 82. The connecting rope 81 is an elastic rope. The elastic rope 81 helps to better place the U-shaped plate 82.
[0034] Working principle: When the vortex aerator 1 needs to be used in the water source, firstly, the air intake system is connected to the flange 6 of the aerator 1 through the support structure 8. Then, the aerator 1 is moved to the bottom of the sewage tank. At this time, the aerator 1 is started. The aerator 1 introduces air through the air intake pipe 5. The air forms multiple airflows inside the aerator 1. These airflows generate rotational motion under the action of a special channel structure. Then, they are ejected from the aeration port 2 through the vortex blades 3 at high speed. After being ejected, the water flow impacts the packing block 75, causing the packing block 75 to drive the baffle 74 to move. The baffle 74 then drives the rotating frame 72 to rotate with the help of the fixed frame 71, thereby realizing automatic opening. After rotation, the rotating frame 72 fits against the inner wall of the support plate 73 to prevent the rotation angle from being too tilted. When the aerator 1 stops, the impacted water flow creates a backflow. At this time, the water comes into contact with the inclined plate 77, which improves the success rate of the baffle 74 closing. With the backflow of the inclined plate 77 itself, the inclined plate 77 drives the rotating frame 72 to rotate with the help of the baffle 74. The sealing ring 76 is fitted onto the arc surface of the aerator 1 through the baffle 74, which improves the sealing effect between the baffle 74 and the aerator 1. The filling block 75 contacts the inner wall of the aeration port 2 through the baffle 74. The filling block 75 of the arc-shaped block fills the gap between the baffle 74 and the aeration port 2, thereby quickly completing the automatic closing of the baffle 74 to prevent too many impurities from entering the vortex chamber of the aerator 1 after the water source backflows, which would cause the channel to be blocked.
[0035] When the air intake system needs to be connected to the flange 6, first align the two flanges 6. Then, using the round rod 85 to move the U-shaped plate 82, the long rod 83 is inserted into the hole of the flange 6. The flange 6 can only rotate. At this time, the connecting rope 81 is in a stretched state. Then, rotate the flange 6 slightly to make the hole positions completely aligned. Move the round rod 85 again, using the U-shaped plate 82 to move the positioning rod 84 into the hole of the flange 6. The positioning rod 84 and the long rod 83 are used for positioning, so that the flange 6 cannot rotate or move. At this time, it can be connected by bolts. Finally, pull out the positioning rod 84 and the long rod 83 to connect the remaining holes. The positioning rod 84 plays the role of positioning the flange 6 to rotate. At this time, the connecting rope 81 is in a contracted state, which moves the round rod 85 close to the aerator 1 to return to its position. The connecting rope 81, which is an elastic rope, achieves a better placement of the U-shaped plate 82.
