Description

Technical Field

[0001] This utility model relates to the field of tailwater treatment, specifically an aeration equalization tank for tailwater treatment. Background Technology

[0002] An aeration tank is a biochemical reactor designed based on the characteristics of microorganisms. Aeration is a method of intensely contacting air and water, aiming to dissolve oxygen from the air into the water or to release unwanted gases and volatile substances from the water into the air. It promotes the exchange of substances between gases and liquids, enhancing the contact between organic matter, microorganisms, and dissolved oxygen within the tank, thereby ensuring that microorganisms in the tank can oxidize and decompose organic matter in wastewater under conditions of sufficient dissolved oxygen.

[0003] For the treatment of wastewater generated by the aquaculture industry, a relatively large aeration tank is required to meet the efficiency requirements of wastewater purification. During the aeration process, agitation is necessary. Aeration and agitation is an important technical means in the field of water treatment. It combines the dual functions of aeration and agitation. By forcibly introducing air into the water and simultaneously agitating it, oxygenation, mixing, and pollutant removal of the water are achieved. However, using large agitation devices for relatively large aeration tanks will increase investment costs. Furthermore, effective aeration will not be possible at the ends and corners of the aeration tank. Utility Model Content

[0004] The purpose of this utility model is to provide an aeration equalization tank for tailwater treatment in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aeration regulating tank for tailwater treatment, comprising an aeration tank, wherein two slide rails are symmetrically arranged at both ends of the upper opening of the aeration tank, and a movable frame is installed between the two slide rails. The movable frame is slidably connected to the slide rails via a sliding seat, and multiple sets of stirring blades are equidistantly installed along the length direction of the movable frame; a driving mechanism is provided between the aeration tank, the movable frame, and the multiple sets of stirring blades, for driving the multiple sets of stirring blades to move and rotate along the length direction of the slide rails, so that the multiple sets of stirring blades can perform overall stirring of the aerated tailwater in the aeration tank.

[0006] As a further embodiment of this utility model: the driving mechanism includes a first connecting rod, which is mounted on the top of the opening of the aeration tank. A first toothed groove is provided on one side wall of the first connecting rod. A motor is installed in the middle of the moving frame. A first gear is connected to the output end of the motor, and the first gear meshes with the first toothed groove.

[0007] As a further improvement of this utility model: the first connecting rod is located between the two slide rails, and the first connecting rod is arranged parallel to the slide rails.

[0008] As a further embodiment of this utility model: the driving mechanism further includes multiple second connecting rods, which are equidistantly arranged at the upper end of the inner cavity of the aeration tank. Each of the multiple second connecting rods has a second tooth groove on one side wall. A second gear is fixedly sleeved on the upper outer wall of the stirring paddle, and the second gear meshes with the second tooth groove.

[0009] As a further embodiment of this utility model: multiple second connecting rods are arranged parallel to the slide rail, and the second gear and the second connecting rod are at the same horizontal position and height, and the number of stirring paddles is the same as the number of second connecting rods.

[0010] As a further improvement of this utility model: the top of the movable frame is provided with a mounting hole for the upper end of the stirring paddle to pass through, and the mounting hole is rotatably connected to the upper end of the stirring paddle through a bearing.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention uses a drive mechanism to move and stir multiple sets of agitators within the aeration tank, ensuring uniform mixing of the effluent in various parts of the tank. This results in a more even distribution of pollutants, microorganisms, and dissolved oxygen in the effluent, improving treatment efficiency. Especially for larger aeration tanks, this invention not only reduces energy consumption and operating costs but also effectively adjusts the aeration intensity, preventing over-aeration or under-aeration.

[0017] 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.

[0018] Please see Figures 1-3 In this embodiment of the present invention, an aeration regulating tank for tailwater treatment includes an aeration tank 1. Two slide rails 2 are symmetrically arranged at both ends of the upper opening of the aeration tank 1. A movable frame 3 is installed between the two slide rails 2. The movable frame 3 is slidably connected to the slide rails 2 via a sliding seat 32. Multiple sets of stirring paddles 5 are equidistantly installed along the length of the movable frame 3. A mounting hole 31 is provided at the top of the movable frame 3 for the upper end of the stirring paddle 5 to pass through. The mounting hole 31 is rotatably connected to the upper end of the stirring paddle 5 via a bearing. The stirring paddle 5 includes a vertically arranged rod body, with stirring blades installed at the lower end of the rod body.

[0019] A drive mechanism 4 is provided between the aeration tank 1, the movable frame 3 and the multiple sets of stirring blades 5, which is used to drive the multiple sets of stirring blades 5 to move and rotate along the length of the slide rail 2, so that the multiple sets of stirring blades 5 can stir the tailwater of the aeration tank 1 as a whole.

[0020] The drive mechanism 4 includes a first connecting rod 401, which is mounted on the top of the opening of the aeration tank 1. A first toothed groove 402 is provided on one side wall of the first connecting rod 401. A motor 403 is installed in the middle of the movable frame 3. A first gear 404 is connected to the output end of the motor 403. The first gear 404 meshes with the first toothed groove 402. The first connecting rod 401 is located between two slide rails 2 and is arranged parallel to the slide rails 2.

[0021] The drive mechanism 4 also includes multiple second connecting rods 405, which are equidistantly arranged at the upper end of the inner cavity of the aeration tank 1. Each of the multiple second connecting rods 405 has a second toothed groove 406 on one side wall. A second gear 407 is fixedly sleeved on the upper outer wall of the stirring paddle 5, and the second gear 407 meshes with the second toothed groove 406. The multiple second connecting rods 405 are all arranged parallel to the slide rail 2, and the second gear 407 and the second connecting rods 405 are at the same horizontal position and height. The number of stirring paddles 5 is the same as the number of second connecting rods 405.

[0022] In this embodiment: Aquaculture needs to adjust the aeration rate according to water quality, water quantity and microbial needs to avoid over-aeration or under-aeration. Secondly, it is necessary to ensure that the stirring intensity is moderate so as to prevent sludge sedimentation without damaging the bioflocs. In addition, the aerators, stirrers and pipes should be checked regularly for blockage and wear, and cleaned or replaced in time.

[0023] This solution uses a drive mechanism 4 to drive multiple sets of stirring paddles 5 to move and stir within the aeration tank 1. This allows the multiple sets of stirring paddles 5 to uniformly stir the effluent in various parts of the aeration tank 1, ensuring a uniform distribution of pollutants, microorganisms, and dissolved oxygen in the effluent from aquaculture, thus improving treatment efficiency. Secondly, especially for larger aeration tanks, this solution not only reduces energy consumption and operating costs but also effectively adjusts the aeration intensity of the aeration tank, preventing problems such as over-aeration or under-aeration.

[0024] Specifically, for a relatively large aeration tank 1, this solution utilizes multiple sets of small-sized stirring paddles 5 to perform aeration and stirring treatment inside the aeration tank 1. First, the motor 403 drives the first gear 404 to rotate. Under the meshing action of the first tooth groove 402, the rotating motor 403 pushes the moving frame 3 to move along the length direction of the slide rail 2. During the movement of the moving frame 3, multiple sets of stirring paddles 5 are also driven to move along the length direction of the slide rail 2. At the same time, the second gear 407 on the stirring paddle 5 drives the stirring paddle 5 to rotate, thereby forming a stirring efficiency. The operation steps are simple and convenient, and the aeration and stirring structure is also complex. Low-power reciprocating stirring can be used instead of high-power stirring. This not only achieves the aeration and stirring effect in each section of the aeration tank 1, but also greatly reduces the investment cost and reduces excessive energy consumption.

[0025] The stirring speed of the agitator 5 is affected by the moving speed of the moving frame 3. If the aeration is excessive, the moving speed of the moving frame 3 will be reduced to make the agitator 5 move and rotate relatively slowly. Conversely, when the aeration is insufficient, the moving speed of the moving frame 3 can be increased, and the stirring speed of the agitator 5 will also be increased.

[0026] It should be noted that the bottom of the aeration tank 1 in this solution is equipped with pipes for aeration. This solution does not address existing aeration devices and will not be elaborated upon further. Furthermore, the reciprocating movement of the moving frame 3 can be controlled by rotating the motor 403 in both directions.

[0027] 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.
