Description

TECHNICAL FIELD

[0001] The application relates to the technical field of sewage treatment equipment, in particular to energy-saving sewage treatment aeration equipment. BACKGROUND

[0002] In the sewage treatment process, aeration is a very critical link. The main role of aeration is to fill enough oxygen into the sewage to provide a suitable environment for the growth and reproduction of microorganisms and promote the decomposition of organic matter in the sewage by microorganisms, so as to achieve the purpose of sewage purification. At present, the common sewage treatment aeration equipment on the market mostly adopts the mode of motor driving for aeration. However, such aeration equipment driven by the motor has a serious problem of high energy consumption.

[0003] From the operation principle of the equipment, the motor needs to run continuously, and drives the aeration components to work through mechanical transmission to realize the function of blowing air into the sewage. In this process, the power consumption of the motor is not only used to drive the aeration components, but also has various energy losses such as mechanical friction loss, electric energy-mechanical energy conversion efficiency loss, etc. For a sewage treatment plant with a large treatment scale, the number of equipment is large, and the long-term accumulated power consumption leads to a substantial increase in the cost of sewage treatment.

[0004] In addition, in order to ensure the sewage treatment effect, the aeration equipment often needs to run continuously for a long time, which further aggravates the energy consumption problem. Long-term high-load operation causes the motor to heat seriously, and in order to ensure the normal operation of the motor, an additional cooling system such as a fan, a water cooling device, etc. needs to be equipped, which also needs to consume a large amount of electric energy, forming a vicious cycle. Moreover, high energy consumption also brings great pressure on power supply. During the peak period of electricity consumption, the normal operation of the sewage treatment plant may be affected due to insufficient power supply, thereby potentially threatening the surrounding ecological environment and residents' life.

[0005] Therefore, the application provides an energy-saving sewage treatment aeration equipment to solve the problems in the above background. Practical new type content

[0008] Optionally, the water flow driving mechanism comprises a fixing frame fixed in the flow guide channel, a rotatable rotating shaft is arranged on the fixing frame, and a flow guide impeller is arranged at one end of the rotating shaft and rotatably connected in the flow guide channel, so that the flow guide impeller is driven to rotate when water flows through the flow guide impeller.

[0023] Reference Figure 1 , Figure 4As shown in one embodiment: energy-saving sewage treatment aeration equipment includes a floating body 1, in this embodiment, the floating body 1 is a structure with a certain buoyancy, which is made of light material with a density less than water, such as plastic material, and is floated on the surface of sewage by its own buoyancy, providing floating support for the entire device, which can be tied to the floating body 1 in the sewage flow channel using a rope. The middle part of the floating body 1 is fixedly connected with a flow guide cylinder 2, and the two are tightly fixed by bolt connection to ensure the stable installation of the flow guide cylinder 2. One end of the flow guide cylinder 2 is processed into a horn-shaped structure, and the large end thereof faces the flow direction of the sewage. Such design is conducive to guiding the smooth entry of sewage into the flow guide cylinder 2. A through flow guide channel 3 is formed in the middle part of the flow guide cylinder 2, which provides a path for the flow of sewage. A water flow driving mechanism 4 is arranged in the flow guide channel 3, and the water flow driving mechanism 4 is connected and fixed with the inner wall of the flow guide cylinder 2 by a fixing frame 7. A plurality of aeration mechanisms 5 are arranged on the top of the flow guide cylinder 2, and a transmission mechanism 6 is arranged between each aeration mechanism 5 and the water flow driving mechanism 4. The two ends of the transmission mechanism 6 are respectively connected with the water flow driving mechanism 4 and the aeration mechanism 5 by gear meshing or other means to realize power transmission.

[0024] The implementation principle of the above embodiment is that when the device is placed in sewage, the floating body 1 floats on the surface of the sewage, and the sewage enters the flow guide channel 3 from the large end of the horn-shaped flow guide cylinder 2 under the action of its own flow. The sewage impacts the water flow driving mechanism 4 during the flow through the flow guide channel 3, causing the water flow driving mechanism 4 to rotate. The rotation of the water flow driving mechanism 4 transmits power to the aeration mechanism 5 through the transmission mechanism 6, thereby driving the aeration mechanism 5 to work, realizing the aeration treatment of the sewage. This structure design utilizes the water flow power of the sewage itself to drive the aeration process, without the need for an additional power source, achieving the purpose of energy saving.

[0025] Referring to Figure 4 , Figure 5 As shown in one embodiment: the water flow driving mechanism 4 includes a fixing frame 7, which is a frame structure made of metal material and is fixed on the inner wall of the flow guide channel 3 by bolt fixation to provide installation support for the rotating shaft 8 and the flow guide impeller 9. The fixing frame 7 is provided with an axle hole, and the rotating shaft 8 is installed in the axle hole through a bearing, so that the rotating shaft 8 can freely rotate on the fixing frame 7. The rotating shaft 8 is fixedly installed with a flow guide impeller 9 at one end, and the flow guide impeller 9 is fixed with the rotating shaft 8 by key connection or welding, to ensure synchronous rotation of the two. The flow guide impeller 9 is rotatably connected in the flow guide channel 3, and a certain gap is left between the edge of the flow guide impeller 9 and the inner wall of the flow guide channel 3, which can ensure the free rotation of the flow guide impeller 9 and prevent a large amount of sewage from leaking from the gap.

[0026] The implementation principle of the above embodiment is that when the sewage flows into the guide channel 3, the water flow impacts the blades of the guide vane 9. Since the blades have a certain inclination angle, the water flow generates a force on the blades, thereby driving the guide vane 9 to rotate around the rotating shaft 8. The rotation of the guide vane 9 transmits power through the rotating shaft 8 to provide a power source for the subsequent transmission mechanism 6 and the aeration mechanism 5 to work, achieving the purpose of driving the equipment to run by using the energy of the sewage flow.

[0027] Referring to Figure 4 , Figure 5 An embodiment shown in the drawings is that the transmission mechanism 6 includes a transmission shell 10. In this embodiment, the transmission shell 10 is a closed shell structure which is fixed on the fixed frame 7 by welding to ensure stable installation of the transmission shell 10. The transmission shell 10 is internally provided with a driving bevel gear 11 which is fixedly installed on the rotating shaft 8 so that the driving bevel gear 11 can synchronously rotate with the rotating shaft 8. The transmission shell 10 is also internally rotatably connected with a driven bevel gear 12 which is rotatably installed at the top of the transmission shell 10 by a bearing and can freely rotate. The driving bevel gear 11 and the driven bevel gear 12 are in meshing engagement, and the bevel gear surfaces of the two are in close cooperation to achieve power transmission. The center of the driven bevel gear 12 is fixedly connected with a transmission shaft 13 which is fixed with the driven bevel gear 12 by welding or key connection to ensure that power can be transmitted from the driven bevel gear 12 to the transmission shaft 13.

[0028] The implementation principle of the above embodiment is that when the rotating shaft 8 of the water flow driving mechanism 4 drives the driving bevel gear 11 to rotate, since the driving bevel gear 11 is in meshing engagement with the driven bevel gear 12, the rotation of the driving bevel gear 11 will drive the driven bevel gear 12 to rotate around its own axis. The rotation of the driven bevel gear 12 further drives the transmission shaft 13 connected thereto to rotate, transmitting the power generated by the water flow driving mechanism 4 to provide power for the aeration mechanism 5, achieving effective transmission and direction conversion of power.

[0029] Referring to Figure 1 , Figure 2 , Figure 5 An embodiment shown in the drawings is that the aeration mechanism 5 includes an aeration channel 14 which is a through-hole structure provided at the top of the guide cylinder 2. In this embodiment, one end of the aeration channel 14 is in communication with the guide channel 3, and the other end is in communication with the outside air to provide a path for air to enter the guide channel 3. The aeration channel 14 is internally provided with an aeration impeller 15 which is fixedly installed on the corresponding transmission shaft 13 by key connection to ensure that the aeration impeller 15 can synchronously rotate with the transmission shaft 13. The transmission shaft 13 penetrates through the transmission shell 10 and is in close connection with the aeration impeller 15 to achieve power transmission.

[0030] The implementation principle of the above embodiment is that when the transmission shaft 13 of the transmission mechanism 6 rotates, the aeration impeller 15 fixed thereon rotates in the aeration channel 14. Since the aeration impeller 15 adopts a spiral blade structure, the spiral blades continuously stir the air during rotation, and the air is sucked into the flow guide channel 3 through the aeration channel 14 by using the principle of aerodynamics. After the air enters the flow guide channel 3, it is fully mixed with the sewage, realizing the aeration process of the sewage and improving the content of dissolved oxygen in the sewage, thereby promoting the decomposition of organic matter in the sewage by microorganisms.

[0031] Referring to Figure 2 , Figure 4 , Figure 5 An embodiment shown in the figure is that the aeration impeller 15 adopts a spiral blade structure, and in this embodiment, the spiral blades are spirally distributed on the impeller shaft, and the spiral shape can generate air suction during rotation to suck external air. The blade surface is provided with a plurality of protrusions 16 by mechanical processing or injection molding, and the protrusions 16 are uniformly distributed on the blade surface. The aeration impeller 15 is fixedly installed on the transmission shaft 13 through a shaft hole, and the shaft hole and the transmission shaft 13 are connected in an interference fit or a key connection manner, so as to ensure that the aeration impeller 15 is stably installed and can rotate with the transmission shaft 13.

[0032] The implementation principle of the above embodiment is that when the aeration impeller 15 rotates under the driving of the transmission shaft 13, the spiral blade structure sucks external air by using the negative pressure generated by air flow. The protrusions 16 on the blade surface increase the contact area and friction force between the blade and the air, further disturb the air, so that the air fully contacts the blade before entering the flow guide channel 3, thereby more effectively sucking the air into the flow guide channel 3. At the same time, the protrusions 16 can also break and disperse the air entering the flow guide channel 3, so that the air is more uniformly mixed with the sewage, improving the aeration effect and enhancing the sewage treatment efficiency.

[0033] The working principle of the device is that when the device works, the floating body 1 makes the device float on the surface of the sewage, and the large opening end of the flow guide cylinder 2 faces the water flow. The sewage flows into the flow guide channel 3 and impacts the flow guide impeller 9, and due to the inclination of the blades, the water flow force makes it rotate around the rotating shaft 8. The rotating shaft 8 drives the driving bevel gear 11 fixed thereon to rotate, and meshes with the driven bevel gear 12 to transmit power to the driven bevel gear 12, thereby driving the transmission shaft 13 to rotate. The transmission shaft 13 is connected with the aeration impeller 15, and drives the aeration impeller 15 to rotate in the aeration channel 14. The spiral blade structure of the aeration impeller 15 generates negative pressure by using the principle of aerodynamics during rotation, and sucks external air into the flow guide channel 3. The protrusions 16 on the blade surface further disturb the air, break and disperse the air flow, so that the air is fully mixed with the sewage to complete the aeration process. The whole process does not need an additional power source, and relies on the water flow energy of the sewage itself to drive, realizing energy-saving aeration.

[0034] The working principle of the device has been described through the above-mentioned embodiments, and the above-mentioned embodiments only express several implementation manners of the device, the description is more specific and detailed, but it cannot be understood as the limitation of the scope of the utility model patent. It should be pointed out that for ordinary skilled persons in the art, without departing from the concept of the utility model, a number of modifications and improvements can be made, which belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent should be subject to the appended claims.
