DETAILED DESCRIPTION

[0023] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: an oxygen supply device for water for microbial sewage treatment, comprising a sewage pool 1, a delivery pipe 3 penetrating the surface of the sewage pool 1 is fixedly connected to the surface of the sewage pool 1, and is used to input sewage into the sewage pool 1, and an air delivery pipe 7 penetrating the surface of the sewage pool 1 is fixedly connected to the bottom of the sewage pool 1, and a Roots blower can be set at one end of the air delivery pipe 7 located outside the sewage pool 1. This is a conventional technical means for personnel in this field and will not be explained in detail.

[0025] The surface of the sewage pool 1 is fixedly connected to a frame plate 2, the surface of the frame plate 2 is rotatably connected to a connecting shaft 8 that penetrates the surface of the frame plate 2, the lower end of the connecting shaft 8 is slidably connected to an aeration pipe 6, and the aeration pipe 6 and the connecting shaft 8 can be connected by a spline, so that the connecting shaft 8 drives the aeration pipe 6 to rotate synchronously and the connecting shaft 8 and the aeration pipe 6 can slide with each other, thereby ensuring the smooth operation of the device.

[0026] Furthermore, the surface of the air supply pipe 7 located inside the sewage pool 1 is fixedly connected to an exhaust pipe 14 connected to the inside of the air supply pipe 7, a connecting pipe 12 is provided at the upper end of the exhaust pipe 14, and a rotating flange 11 is provided between the connecting pipe 12 and the aeration pipe 6. The setting of the rotating flange 11 ensures that the aeration pipe 6 is connected to the connecting pipe 12 while not affecting the rotation of the aeration pipe 6 on the connecting pipe 12, thereby ensuring the smooth operation of the device.

[0027] The inner wall of the exhaust pipe 14 is fixedly connected with a fixing frame 21, and the inner wall of the fixing frame 21 is fixedly connected with a fixing shaft 19. The inner wall of the aeration pipe 6 is also provided with a fixing frame 21. The inner wall of the fixing frame 21 on the aeration pipe 6 is rotatably connected with a mounting shaft 18. The lower end of the mounting shaft 18 corresponds to the upper end of the fixing shaft 19. The lower end of the mounting shaft 18 is fixedly connected with a square rod 22. The surface of the square rod 22 is slidably connected to the inside of the fixing shaft 19. Then, through the setting of the square rod 22, the mounting shaft 18 and the fixing shaft 19 can be connected together, so that the mounting shaft 18 and the fixing shaft 19 can rotate synchronously, thereby ensuring the smooth operation of the device.

[0028] Furthermore, the surface of the aeration pipe 6 is rotatably connected to a rotating shaft 16 protruding from the surface of the aeration pipe 6, and one end of the rotating shaft 16 located inside the aeration pipe 6 is fixedly connected to a bevel gear 17, and the surface of the mounting shaft 18 is also fixedly connected to the bevel gear 17, and the bevel gear 17 on the rotating shaft 16 is meshed and connected with the bevel gear 17 on the mounting shaft 18, and the surface of the rotating shaft 16 is fixedly connected to stirring plates 15 arranged equidistantly in a circle, and then through the setting of the stirring plates 15, when the aeration pipe 6 moves, it can rotate back and forth near the aeration pipe 6, thereby disrupting the water flow near the aeration pipe 6, thereby increasing the retention time of oxygen in the water, thereby increasing the utilization efficiency of oxygen by microorganisms in the water, and thereby improving the use effect of the device, which is worthy of promotion.

[0029] Secondly, a fixed cylinder 5 is fixedly connected to the bottom of the frame plate 2, and a symmetrically arranged annular grooves 9 are opened on the inner wall of the fixed cylinder 5, and the annular grooves 9 are undulating. A sliding rod 10 is fixedly connected to the surface of the aeration pipe 6, and the surface of the sliding rod 10 is slidably connected to the inner wall of the annular groove 9. Furthermore, through the arrangement of the annular groove 9 and the sliding rod 10, when the aeration pipe 6 rotates, the inner wall of the annular groove 9 can be used to push or squeeze the surface of the sliding rod 10, so as to drive the aeration pipe 6 to rise and fall in the fixed cylinder 5, so that the device can supply oxygen to different water layers in the sewage pool 1, thereby improving the oxygen supply range of the device to the water body, improving the oxygen supply effect of the device, and having a high promotion value.

[0030] Furthermore, a bellows 20 is fixedly connected to the lower end of the connecting pipe 12, and one end of the bellows 20 away from the connecting pipe 12 is fixedly connected to the upper end of the exhaust pipe 14, so that the connecting pipe 12 and the exhaust pipe 14 can be changed, and a lug 23 is fixedly connected to the surface of the connecting pipe 12, and a lug 23 is also fixedly connected to the surface of the exhaust pipe 14, and a reinforcing rod 13 is fixedly connected to the surface of the lug 23 on the connecting pipe 12, and the reinforcing rod 13 passes through the surface of the lug 23 on the exhaust pipe 14 and is slidably connected to the inside of the lug 23, and then through the setting of the reinforcing rod 13, the connection between the connecting pipe 12 and the exhaust pipe 14 is strengthened, thereby avoiding the situation where the aeration pipe 6 drives the connecting pipe 12 to rotate when rotating, and then the bellows 20 is torn, thereby ensuring the smooth operation of the device.

[0031] The surface of the frame plate 2 is fixedly connected with a motor 4, and the output end of the motor 4 and the upper end of the connecting shaft 8 are also provided with a bevel gear 17, thereby ensuring that when the output end of the motor 4 rotates, it can drive the connecting shaft 8 perpendicular to the frame plate 2 to rotate, thereby ensuring the smooth operation of the device.

[0032] Specifically, when in use, the motor 4 is started, thereby driving the connecting shaft 8 to rotate, and driving the aeration pipe 6 to rotate. When the aeration pipe 6 rotates, it drives the rotating shaft 16 and the stirring plate 15 to run in a circle. At the same time, since the bevel gear 17 on the rotating shaft 16 is meshed with the bevel gear 17 on the mounting shaft 18, and the mounting shaft 18 is restricted by the fixed shaft 19 through the square rod 22 and cannot rotate, the bevel gear 17 on the mounting shaft 18 is in a stationary state. At this time, the bevel gear 17 on the rotating shaft 16 is on the bevel gear 19 on the mounting shaft 18. The surface of 7 rolls, thereby driving the rotating shaft 16 to rotate, thereby driving the stirring plate 15 to rotate, so that when the device is in the aeration pipe 6 supplying oxygen to the sewage pool 1, the rotating shaft 16 and the stirring plate 15 near the aeration pipe 6 can rotate around the aeration pipe 6 while rotating, thereby stirring the water flow near the air hole of the aeration pipe 6, thereby disturbing the water flow, so that oxygen can stay in the water flow for a longer time, thereby improving the utilization rate of the oxygen cable, improving the use effect of the device, and having a high promotion value.

[0033] Secondly, when the aeration pipe 6 rotates, the slide rod 10 is driven to slide in the annular groove 9, and then the slide rod 10 is pushed or squeezed by the inner wall of the annular groove 9, so that the slide rod 10 is continuously lifted and lowered, thereby driving the aeration pipe 6 to be continuously lifted and lowered. At the same time, the connecting pipe 12 is lifted and lowered by rotating the flange 11, and the bellows 20 is stretched or compressed. At the same time, the square rod 22 and the fixed shaft 19 slide against each other, thereby expanding the oxygen supply range of the device to the water body.

[0034] Working principle: start the motor 4, which in turn drives the connecting shaft 8 to rotate, and drives the aeration pipe 6 to rotate. When the aeration pipe 6 rotates, it drives the rotating shaft 16 and the stirring plate 15 to run in a circle. At the same time, since the bevel gear 17 on the rotating shaft 16 is meshed with the bevel gear 17 on the mounting shaft 18, and the mounting shaft 18 is restricted by the fixed shaft 19 through the square rod 22 and cannot rotate, the bevel gear 17 on the mounting shaft 18 is in a stationary state. At this time, the bevel gear 17 on the rotating shaft 16 rolls on the surface of the bevel gear 17 on the mounting shaft 18, thereby driving the rotating shaft 16 to rotate, thereby driving the stirring plate 15 to rotate.

[0035] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
