DETAILED DESCRIPTION

[0019] In order to further understand the content, features and effects of the utility model, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0020] The structure of the utility model is described in detail below in conjunction with the accompanying drawings.

[0021] like Figures 1 to 4 As shown, an aeration device for sewage treatment provided by an embodiment of the utility model comprises an aeration tank 6, an air pump 7, an aeration pipe 1 and a plurality of aeration heads 101, the air pump 7 is fixedly mounted at one end of the aeration tank 6, one end of the aeration pipe 1 is rotatably connected to the output end of the air pump 7 via a connecting sleeve 8, a plurality of aeration heads 101 are arranged in a row on the aeration pipe 1, annular limiting rods 5 are fixedly mounted on the side walls at both ends of the aeration tank 6, both ends of the aeration pipe 1 are rotatably connected to the annular limiting rods 5 via a first movable frame 4 and a second movable frame 9 respectively, a stirring mechanism 2 is rotatably arranged in the middle of the aeration tank 6, a transmission mechanism 3 is arranged at one end of the stirring mechanism 2, and the transmission mechanism 3 is connected to the second movable frame 9 via a sleeve 10.

[0022] Furthermore, a first sealing sleeve 102 and a second sealing sleeve 11 are fixedly installed inside both ends of the aeration tank 6, and the aeration pipe 1 and the sleeve 10 rotate through the first sealing sleeve 102 and the second sealing sleeve 11 respectively. A connecting head 401 is provided on one side of the upper end of the first movable frame 4 and the second movable frame 9, and the two connecting heads 401 are respectively rotatably connected to the two annular limit rods 5.

[0023] In the present application, air is filled into the aeration pipe 1 through an air pump 7, and then introduced into the sewage from a plurality of aeration heads 101. The oxygen in the air dissolves in the sewage, increasing the dissolved oxygen content in the sewage, thereby facilitating further decomposition and transformation of organic matter. The aeration pipe 1 is Z-shaped, and the aeration pipe 1 can be guided to limit the position through the rotation cooperation between the first movable frame 4, the second movable frame 9 and the annular limit rod 5, thereby improving the stability of the aeration pipe 1 during rotation, wherein the annular limit rod 5 coincides with the center line of the aeration pipe 1, which can ensure that the aeration pipe 1 rotates along the center line.

[0024] Furthermore, the stirring mechanism 2 includes a motor 201, a mounting rod 202 and a plurality of stirring blades 203. The motor 201 is fixedly mounted at one end of the aeration tank 6 away from the air pump 7. The output end of the motor 201 is fixedly connected to the mounting rod 202. One end of the mounting rod 202 is rotatably connected to the sleeve 10, and the other end is rotatably connected to the lower end of the first movable frame 4. The plurality of stirring blades 203 are evenly distributed on the mounting rod 202 in a row.

[0025] It can be understood that, in the present application, the center line of the mounting rod 202 coincides with the center line of the annular limiting rod 5, one end of the mounting rod 202 is directly rotatably connected to the lower end of the first movable frame 4, and the other end is rotatably connected to the lower end of the second movable frame 9 through the sleeve 10. The first movable frame 4 and the second movable frame 9 can support the mounting rod 202, thereby ensuring the stability of the mounting rod 202 during rotation. By starting the motor 201 to drive the mounting rod 202 and the stirring blade 203 to rotate, the flow of sewage can be accelerated, the substances in the sewage can be evenly distributed, and the mixing of oxygen and sewage can be accelerated, thereby improving the treatment effect.

[0026] Furthermore, one end of the sleeve 10 is rotatably connected to the second sealing sleeve 11 , and the other end is fixedly connected to one side of the lower end of the second movable frame 9 .

[0027] In a specific configuration, the sleeve 10 rotates and penetrates the second sealing sleeve 11 , and the mounting rod 202 rotates and penetrates the interior thereof. When the sleeve 10 rotates, the second movable frame 9 rotates synchronously, thereby driving the aeration pipe 1 to rotate.

[0028] Furthermore, the transmission mechanism 3 includes a reduction gear group and a transmission group, the reduction gear group includes a driving gear 301 and a driven gear 302, the driving gear 301 is fixedly sleeved on one end of the mounting rod 202, the driven gear 302 is rotatably installed on one side of the aeration tank 6 through the mounting shaft 306, the driving gear 301 is meshed and connected with the driven gear 302, the transmission group includes a first transmission shaft 303, a second transmission shaft 304 and a transmission belt 305, the first transmission shaft 303 and the second transmission shaft 304 are fixedly sleeved on the sleeve 10 and the mounting shaft 306 respectively, and the transmission belt 305 is sleeved on the first transmission shaft 303 and the second transmission shaft 304.

[0029] In the specific setting, by setting a reduction gear set, the installation shaft 306 and the installation rod 202 can rotate simultaneously and at a reduced speed. The installation shaft 306 drives the first transmission shaft 303 to rotate at a reduced speed, so that the sleeve 10 drives the second movable frame 9 to rotate at a reduced speed, and then the installation rod 202 and the stirring blade 203 rotate at a relatively high speed while the aeration pipe 1 rotates at a relatively low speed and in the opposite direction. By rotating the aeration pipe 1, oxygen can be more evenly distributed in the entire aeration tank 6, avoiding local hypoxia or oversaturation. The above technical solution can accelerate sewage convection, promote material exchange and reaction, and improve treatment efficiency.

[0030] The working principle of this utility model:

[0031] First, the air pump 7 is started to fill the aeration pipe 1 with air, and the air is passed into the sewage from the aeration heads 101. The oxygen in the air dissolves in the sewage, increasing the dissolved oxygen content in the sewage, which is helpful for the decomposition and transformation of organic matter. Then, the motor 201 is started to drive the mounting rod 202 and the stirring blade 203 to rotate, and the sewage in the middle of the aeration tank 6 is stirred to make the substances in the sewage evenly distributed. The mounting rod 202 drives the driving gear 301 and the driven gear 302 to rotate at the same time, and the driven gear 302 drives the sleeve 10 and the second movable frame 9 to rotate, and the second movable frame 9 drives the aeration pipe 1 to rotate slowly, so that the oxygen is more evenly distributed in the entire aeration tank 6, avoiding local hypoxia or oversaturation, improving the treatment efficiency, and ensuring the treatment effect.

[0032] In summary, the aeration device for sewage treatment drives the mounting rod 202 and the stirring blade 203 to rotate by the motor 201, which can accelerate the flow of sewage, evenly distribute the substances in the sewage, and accelerate the mixing of oxygen and sewage, thereby improving the treatment effect. By setting a reduction gear set and a transmission set, the aeration pipe 1 can be driven to rotate while the stirring blade 203 rotates, so that the oxygen is more evenly distributed in the entire aeration tank 6, avoiding local hypoxia or oversaturation, and improving the treatment efficiency.
