Description

Technical Field

[0001] This utility model relates to the field of water pollution treatment technology, specifically to an aeration device for water pollution treatment. Background Technology

[0002] Aeration devices for water pollution treatment are a type of equipment that introduces air or oxygen-enriched gas into water bodies to increase the dissolved oxygen content, promote the aerobic decomposition and biodegradation of organic matter, and cause air to form tiny bubbles in the water. These bubbles come into contact with organic pollutants and microorganisms in the water, thereby increasing the oxygen mass transfer rate and improving the oxygen conditions of the water body.

[0003] In existing technologies, gas spraying is relatively limited, resulting in poor overall aeration effects and potentially affecting the efficiency of water pollution treatment.

[0004] To overcome the above shortcomings, a prior art Chinese patent (publication number CN218290590U) discloses an aeration treatment device for water pollution treatment, including an operating frame. A connecting plate is fixedly connected to the upper edge of the operating frame. A sliding groove is formed inside the connecting plate, and a slider is slidably connected inside the sliding groove. A threaded hole is formed through the inside of the slider, and a threaded rod is movably connected inside the slider. A rotating shaft is fixedly connected to the upper end of the threaded rod, and a motor is provided at the other end of the rotating shaft. The motor, in conjunction with the threaded rod and the slider, can move the horizontal plate, thereby adjusting the position of the blower box and the aeration box. This allows the device to be adjusted according to the depth of the sewage aeration tank, greatly increasing its applicability and reducing limitations. The baffle can block the sludge generated during aeration, preventing it from entering the aeration box and clogging the aeration nozzles, while also improving the gas flow efficiency.

[0005] While existing technologies can overcome the shortcomings mentioned above, other problems still exist in their operation, such as: the overall size is relatively large, making it inconvenient for users to carry and transport, and the direction of the gas sprayed during aeration in water pollution treatment aeration devices is relatively unidirectional, resulting in poor overall efficiency. Utility Model Content

[0006] The purpose of this utility model is to provide an aeration device for water pollution treatment, so as to solve the problems mentioned in the background art, which are that the whole device is relatively large, which is inconvenient for users to carry and move, and the gas sprayed in a relatively unidirectional direction during aeration, resulting in poor overall efficiency.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an aeration device for water pollution treatment, comprising a main rod and an air pipe connected to the upper end of the main rod, wherein first aeration ports are equally spaced on the surface of the main rod, and an auxiliary aeration mechanism is provided at the bottom of the main rod to improve aeration efficiency; a fixing plate is installed at the upper end of the main rod, and an auxiliary floating mechanism is provided on the outer side of the fixing plate.

[0008] Furthermore, a base plate is installed at the bottom of the main rod, and the base plate is disc-shaped, with second aeration ports evenly spaced around the periphery of the base plate.

[0009] Furthermore, the first aeration port is elongated, and the second aeration port is circular.

[0010] Furthermore, the auxiliary aeration mechanism is provided with a limiting sleeve, which is fixedly installed on the inner wall of the main rod, and a drive rod is rotatably installed inside the limiting sleeve.

[0011] Furthermore, a fan wheel is fixedly installed at the upper end of the drive rod, and the upper end of the fan wheel is aligned with the lower end of the air pipe. The lower end of the drive rod is fixedly installed at the center of the base plate, and a connection port is provided at the upper end of the base plate where it connects with the main rod.

[0012] Furthermore, the auxiliary floating mechanism is provided with a folding plate, and the end of the folding plate is rotatably connected to the fixed plate. A float plate is fixedly installed at the lower end of the folding plate, and a rubber sleeve is provided at the rotatable connection between the end of the folding plate and the fixed plate.

[0013] Furthermore, a movable plate is fixedly installed at the middle end of the drive rod, and the movable plate is inclined. An auxiliary scraper is sleeved inside the movable plate, and a pressure spring is provided between the end of the auxiliary scraper and the movable plate. The outer side of the auxiliary scraper is attached to the inner wall of the first aeration port of the main rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. By setting up a wind turbine, high-pressure gas acts on the wind turbine, and the drive rod rotates under the constraint of the limit sleeve. As the drive rod rotates, it can drive the bottom plate to rotate together. When the bottom plate rotates, high-pressure gas enters its interior through the inlet and is sprayed out from the second aeration port on the periphery of the bottom plate. Combined with the rotation of the bottom plate, the jet direction can be evenly distributed, thereby improving the efficiency of the aeration process in the water pollution treatment process.

[0015] 2. A fixed plate is installed at the upper end of the main pole, and folding plates are rotatably connected around it. The connection between the folding plates and the fixed plate is equipped with a damped rubber sleeve, which can increase the rotational friction and keep the folding plates stable after unfolding. A float plate is added to the bottom of the folding plates to enhance the overall buoyancy. When transporting or carrying, the folding plates can be rotated and folded up to achieve convenient storage and handling.

[0016] 3. While the drive rod rotates the base plate, it also drives the movable plate to rotate. Both the movable plate and the auxiliary scraper are designed with an inclination to avoid interference from the edge of the first aeration port when the auxiliary scraper rotates. The auxiliary scraper is pressed against the first aeration port on the inner wall of the main rod by the pressure spring inside the movable plate, and can continuously clean the aeration port position when it rotates with the drive rod.

[0025] 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.

[0026] Example 1: As Figures 1-4 The technical solution shown is an aeration device for water pollution treatment. To solve the problem of poor aeration effect due to the relatively unidirectional aeration, the device discloses: a main rod 1 and an air pipe 2 connected to the upper end of the main rod 1. The surface of the main rod 1 is provided with first aeration ports 3 at equal intervals, and the bottom of the main rod 1 is provided with an auxiliary aeration mechanism to improve aeration efficiency. The bottom of the main rod 1 is equipped with a base plate 4, which is disc-shaped. The outer periphery of the base plate 4 is provided with second aeration ports 5 at equal intervals. The first aeration ports 3 are elongated, and the second aeration ports 5 are circular. The auxiliary aeration mechanism is provided with a limiting sleeve 7, which is fixedly installed on the inner wall of the main rod 1. A drive rod 8 is rotatably installed inside the limiting sleeve 7. A windmill 9 is fixedly installed on the upper end of the drive rod 8, and the upper end of the windmill 9 is aligned with the lower end of the air pipe 2. The lower end of the drive rod 8 is fixedly installed in the center of the base plate 4. A connection port 6 is provided at the docking position between the upper end of the base plate 4 and the main rod 1.

[0027] In the aeration process for water pollution treatment, the two ends of the main rod 1 are connected to air pipes 2, which are connected to an external high-pressure air pump. The main rod 1 is placed in the water pollution treatment area. By starting the high-pressure air pump, gas is transported through the air pipes 2 into the main rod 1. The gas entering the main rod 1 passes through the first aeration ports 3, which are set at equal intervals, for aeration. Before the gas passes through the first aeration ports 3, it first contacts the impeller 9. Due to the setting of the impeller 9, the high-pressure gas contacts the impeller 9, causing the drive rod 8 to rotate under the limit of the limiting sleeve 7. As the drive rod 8 rotates, it can drive the bottom plate 4 to rotate. When the bottom plate 4 rotates, with the transport of high-pressure gas, the gas passes through the connecting port 6 and enters the bottom plate 4. The air entering the bottom plate 4 can be sprayed out from the second aeration port 5 on the periphery of the bottom plate 4. With the rotation of the bottom plate 4, the spray direction can be made uniform, which can improve the aeration efficiency in the water pollution treatment process.

[0028] Example 2: Figures 1-5 The technical solution shown, based on Embodiment 1, discloses the following to solve the problem of inconvenient placement: a fixing plate 10 is installed at the upper end of the main rod 1, and an auxiliary floating mechanism is provided on the outer side of the fixing plate 10. The auxiliary floating mechanism is provided with a folding plate 11, and the end of the folding plate 11 is rotatably connected to the fixing plate 10. A float plate 12 is fixedly installed at the lower end of the folding plate 11, and a rubber sleeve 13 is provided at the rotatable connection between the end of the folding plate 11 and the fixing plate 10.

[0029] A fixing plate 10 is provided at the upper end of the main rod 1. Folding plates 11 are rotatably installed around the fixing plate 10. Since a damping rubber sleeve 13 is provided at the connection between the folding plate 11 and the fixing plate 10, the rotational friction of the folding plate 11 can be improved. When the folding plate 11 is unfolded, it can be fixed and floated by the float plate 12 provided at the bottom of the folding plate 11, thereby improving buoyancy. Conversely, when transporting and carrying, the folding plate 11 can be rotated to retract it, making it easy to carry.

[0030] Example 3: Figures 1-7 The technical solution shown, based on Embodiment 2, discloses the following to solve the problem of easy clogging: a movable plate 14 is fixedly installed at the middle end of the drive rod 8, and the movable plate 14 is inclined. An auxiliary scraper 15 is sleeved inside the movable plate 14, and a pressure spring 16 is provided between the end of the auxiliary scraper 15 and the movable plate 14. The outer side of the auxiliary scraper 15 is attached to the inner wall of the first aeration port 3 of the main rod 1.

[0031] When the drive rod 8 rotates and drives the base plate 4, the drive rod 8 can drive the movable plate 14 to rotate. Both the movable plate 14 and the auxiliary scraper 15 are inclined to avoid the auxiliary scraper 15 being blocked by the edge of the first aeration port 3 when rotating. The auxiliary scraper 15 is pressed against the position of the first aeration port 3 on the inner wall of the main rod 1 by the pressure spring 16 inside the movable plate 14, and can clean the position of the first aeration port 3 as the drive rod 8 rotates.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
