Description

Technical Field

[0001] This utility model relates to the field of oxidation pond technology, specifically to a centrifugal blower-free self-suspending device for oxidation ponds. Background Technology

[0002] An oxidation pond is a facility that uses the metabolic activities of microorganisms to biologically treat wastewater. It mainly includes biological contact oxidation ponds and oxidation pools. During the operation of the oxidation pond, centrifugal blowers are needed to transport and regulate the gas. A suspension blower is a blower that uses non-contact, non-mechanical friction suspension technology. It mainly includes two types: magnetic suspension blowers and air suspension blowers. The working principle of the air suspension blower is to use the dynamic pressure effect generated when the rotor rotates at high speed to form a high-pressure air film that completely suspends the rotor.

[0003] Existing centrifugal blowers require continuous power supply for suspension operation when regulating gas supply in oxidation tanks, resulting in high energy consumption. Therefore, they do not meet current requirements. To address this, we propose a non-powered self-suspending device for centrifugal blowers in oxidation tanks. Utility Model Content

[0004] The purpose of this invention is to provide a non-powered self-suspending device for centrifugal blowers in oxidation ponds, in order to solve the problem mentioned in the background art that existing centrifugal blowers need to be continuously powered for suspension operation when regulating gas supply in oxidation ponds, resulting in high energy consumption.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifugal blower-free self-suspending device for an oxidation tank, comprising an oxidation tank body, a support frame installed at the upper end of the oxidation tank body, a sealing cover installed on the outer side of the support frame, an air inlet pipe fixedly installed at one end of the front face of the oxidation tank body, a blower mounting cover installed at the upper end of the air inlet pipe, a blower body fixedly installed on the inner side of the blower mounting cover, an air inlet filter plate fixedly installed on one side of the blower mounting cover, multiple return pipes installed at the upper end of the blower mounting cover, an oxygen sensor installed in the middle of the return pipe, and a diversion mesh frame installed at the bottom end of the air inlet pipe on the inner side of the oxidation tank body, with multiple exhaust nozzles on the upper surface of the diversion mesh frame.

[0006] Preferably, an exhaust pipe is installed at the other end of the front face of the oxidation tank, and an inlet pipe and an outlet pipe are installed below the exhaust pipe.

[0007] Preferably, the upper end of the oxidation tank is fixedly connected to the sealing cover by a support frame, an oxidation chamber is provided between the oxidation tank and the sealing cover, the bottom end of the return pipe passes through the sealing cover and the blower mounting cover and is inserted into the inner side of the blower body, and the blower body and the oxidation chamber are connected through multiple return pipes.

[0008] Preferably, the upper end of the fan mounting cover is fixedly connected to multiple oxygen sensors via a return pipe, the bottom end of the oxygen sensor is inserted into the inside of the return pipe, and a solenoid valve is provided on the inside of the return pipe.

[0009] Preferably, the bottom end of the air inlet pipe penetrates the oxidation tank and is connected to multiple exhaust nozzles through a diversion mesh frame. Both the air inlet pipe and the diversion mesh frame are fixedly connected to the oxidation tank. The upper end of the air inlet pipe is higher than the liquid level of the oxidation tank. The upper end of the air inlet pipe is connected to the blower body.

[0010] Preferably, the exhaust pipe, the liquid inlet pipe, and the liquid outlet pipe are all connected in a continuous manner to the oxidation chamber, and a valve body is provided on the inner side of each of the exhaust pipe, the liquid inlet pipe, and the liquid outlet pipe.

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

[0012] This invention connects the bottom of an oxygen sensor to the inside of a return pipe, enabling real-time monitoring of the oxygen concentration in the oxidation chamber. A solenoid valve is installed inside the return pipe. When the oxygen concentration is low, the blower body stops, reducing energy consumption. When the oxygen concentration is too high, the blower body simultaneously extracts and mixes external air and oxygen from the oxidation chamber through the intake filter plate and the return pipe. The mixture is then sequentially transported and distributed through the intake pipe and the distribution frame, facilitating uniform exhaust from multiple exhaust nozzles and reducing the oxygen concentration in the oxidation chamber. The return flow through the return pipe reduces the pressure on the intake filter plate and decreases the oxidation tank's oxygen demand from the external air. During the injection process, exhaust is achieved through the exhaust pipe, balancing the internal pressure of the oxidation tank. Attached Figure Description

[0020] Please see Figures 1 to 3 A fan mounting cover 7 is installed at the upper end of the air intake pipe 6. A fan body 13 is fixedly installed inside the fan mounting cover 7. An air intake filter plate 9 is fixedly installed on one side of the fan mounting cover 7. Multiple return pipes 8 are installed at the upper end of the fan mounting cover 7. The bottom end of the return pipe 8 passes through the sealing cover 2 and the fan mounting cover 7 and is inserted into the inside of the fan body 13. The fan body 13 and the oxidation chamber are connected through multiple return pipes 8. An oxygen sensor 12 is installed in the middle of the return pipe 8. The upper end of the fan mounting cover 7 and multiple oxygen sensors 12 are fixedly connected through the return pipes 8. The bottom end of the oxygen sensor 12 is inserted into the inside of the return pipe 8. A solenoid valve is provided inside the return pipe 8. The oxygen concentration in the oxidation chamber can be monitored in real time through the oxygen sensor 12.

[0021] Please see Figure 3 and Figure 4 The bottom end of the air inlet pipe 6 is located inside the oxidation tank 1 and is equipped with a diversion mesh frame 10. The upper end of the diversion mesh frame 10 is provided with multiple exhaust nozzles 11. The bottom end of the air inlet pipe 6 passes through the oxidation tank 1 and is connected to the multiple exhaust nozzles 11 through the diversion mesh frame 10. Both the air inlet pipe 6 and the diversion mesh frame 10 are fixedly connected to the oxidation tank 1. The upper end of the air inlet pipe 6 is higher than the liquid level of the oxidation tank 1. The upper end of the air inlet pipe 6 is connected to the blower body 13. The blower body 13 can simultaneously extract and mix external air and oxygen in the oxidation chamber through the air inlet filter plate 9 and the return pipe 8.

Then, it is transported and distributed through the air intake pipe 6 and the distribution frame 10 in sequence, so that multiple exhaust nozzles 11 can spray evenly and reduce the oxygen concentration in the oxidation chamber. The return through the return pipe 8 can reduce the pressure of the air intake filter plate 9 and reduce the oxygen demand of the oxidation tank 1 from the external air. During the gas injection process, the exhaust through the exhaust pipe 3 can balance the pressure inside the oxidation tank 1. At the same time, the liquid level inside the oxidation tank 1 can be adjusted through the liquid inlet pipe 4 and the liquid outlet pipe 5.
