Description

Technical Field

[0001] This invention belongs to the field of wastewater aeration technology, specifically relating to a multifunctional aeration device for wastewater treatment. Background Technology

[0002] To accelerate the degradation of organic matter and improve wastewater quality, aeration is often used to enhance wastewater treatment efficiency. Compared to other treatment methods, aeration can significantly reduce wastewater treatment costs and is convenient to use.

[0003] Currently, when aerating livestock and poultry manure wastewater, float-type aerators are often used to reduce the agitation of sediment at the bottom of the pool and prevent its re-suspension. However, because float-type aerators float on the water surface, they are easily affected by external factors such as wind, waves, and water flow, which may lead to aerator displacement or uneven bubble distribution. Therefore, they often need to be tied and secured with connecting ropes or chains. This is inconvenient for daily use when dealing with large wastewater pools that require frequent adjustments to the aeration position. Furthermore, since some livestock and poultry manure wastewater pools are quite large, and the aeration range of float-type aerators is limited, it is often necessary to use additional aerators to improve wastewater treatment efficiency and avoid wasting resources. The aeration position needs to be adjusted according to the dissolved oxygen (DO) concentration. However, due to the large water surface and the presence of a large amount of particulate matter in the water, traditional methods of installing sensors and deploying detection buoys cannot achieve effective detection and are not convenient for practical use. In addition, during the aeration process, livestock and poultry manure wastewater contains more organic matter and protein than other wastewater, which generates a large amount of foam. Existing float-type aerators cannot effectively remove the foam, causing the foam to gradually cover the water surface, reducing the effective dissolution of oxygen, affecting the normal operation of the aerator, and thus reducing the efficiency of wastewater treatment. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional aeration device for wastewater treatment to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A multifunctional aeration device for sewage treatment includes a floating disc, with an installation groove at the center of the top of the floating disc. An aerator is fixedly installed inside the installation groove, and a perforation is provided at the bottom of the installation groove. A three-way pipe is installed inside the perforation. The input end of the three-way pipe is connected to the aerator, and the two output ends of the three-way pipe are connected to an aeration pipe through a second three-way valve. The aeration pipe is located below the floating disc, and the other port of the second three-way valve is connected to a circular pipe through a connecting pipe. Lifting plates are evenly spaced on the circular pipe, and the lifting plates are located between the connecting pipes. A sliding hole is provided on the side wall of the lifting plate, and the circular pipe passes through the sliding hole on the lifting plate.

[0006] Preferably, a controller is also fixedly installed on the inner wall of the mounting groove, an auxiliary component is fixedly installed on the bottom of the floating plate, the auxiliary component is conical, and an auxiliary groove is opened on the top of the auxiliary component. A motor is fixedly installed inside the auxiliary groove, the output end of the motor passes through the auxiliary component, and agitator plates are symmetrically installed at equal intervals on the output end of the motor. A rotating groove is symmetrically opened on the bottom of the floating plate, and the rotating groove is located above the agitator plates.

[0007] Preferably, a bearing is fixedly installed on the output end of the motor, the bearing is used to fill the gap between the output end of the motor and the auxiliary component, and a cover plate is fixedly installed on the top of the inner wall of the mounting groove, the cover plate is used to seal the mounting groove.

[0008] Preferably, the top of the auxiliary component is symmetrically provided with aeration holes, the aeration holes are located on both sides of the auxiliary groove, and the aeration holes are located directly below the second three-way valve, and the aeration pipe passes through the interior of the aeration holes.

[0009] Preferably, the bottom of the auxiliary component is provided with an assembly groove, the assembly groove is located directly below the motor, and a water quality detector is fixedly installed inside the assembly groove, the thickness of the water quality detector being less than the depth of the assembly groove.

[0010] Preferably, a first three-way valve is symmetrically installed at equal intervals on the top of the circular tube, and a first airbag is adhered and fixed to the top of the inner wall of the sliding hole. The first airbag is connected to the circular tube through the first three-way valve.

[0011] Preferably, a second airbag is fixedly installed on the inner wall of the connecting pipe. The second airbag has an annular structure and is located between the floating plate and the circular pipe. The surface of the connecting pipe is symmetrically provided with mounting holes at equal intervals. A nozzle is fixedly installed inside the mounting hole. The nozzle extends through the mounting hole into the interior of the second airbag. The interior of the second airbag is filled with defoaming agent.

[0012] Preferably, a sealing plug is also sealed inside the mounting hole, and the sealing plug is located directly above the second airbag.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The present invention is equipped with a floating plate, a circular tube and a lifting plate. When in use, the floating plate makes the entire device float on the water surface. Under the action of gravity, the lifting plate slides down on the circular tube, causing the lower part of the lifting plate to be embedded in the water. Since the aeration pipe is located between the lifting plates, when aeration is performed, the bubbles will expand outward from the center point of the floating plate and impact the lifting plate. By using multiple arc-shaped lifting plates, the movement resistance of the floating plate in all directions is increased, and the impact of wind, waves and foam on the device is reduced, making the device tend to be stationary. It is convenient to use without the need for ropes and chains.

[0015] (2) The present invention is equipped with a motor, an agitator plate and a first air bag. When in use, the user can remotely adjust and control the speed of the two ends of the motor through the controller, so that it drives the agitator plate to move the float on the water surface. Before moving, the second three-way valve and the first three-way valve can be remotely activated through the controller, so that the external airflow enters the interior of the first air bag after passing through the three-way pipe, the connecting pipe and the round pipe, thereby pushing the lifting plate to move upward, increasing the stability of the float, reducing the movement resistance of the float, and facilitating the quick adjustment of the aeration position of the equipment.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-3 and Figure 8 As shown, the present invention provides the following technical solution: A multifunctional aeration device for sewage treatment includes a floating plate 8, an installation groove 9 is provided at the center of the top of the floating plate 8, an aerator 4 is fixedly installed inside the installation groove 9, and a through hole 25 is provided at the bottom of the installation groove 9. A three-way pipe 15 is provided inside the through hole 25. The input end of the three-way pipe 15 is connected to the aerator 4, and the two output ends of the three-way pipe 15 are connected to the aeration pipe 18 through a second three-way valve 14. The aeration pipe 18 is located below the floating plate 8. The other port of the second three-way valve 14 is connected to the circular pipe 3 through a connecting pipe 7. Lifting plates 6 are provided at equal intervals on the circular pipe 3. The lifting plates 6 are located between the connecting pipes 7, and a sliding hole 24 is provided on the side wall of the lifting plate 6. The circular pipe 3 passes through the sliding hole 24 on the lifting plate 6.

[0028] With the above technical solution, when in use, the float 8 makes the entire device float on the water surface. At this time, since the lifting plate 6 is slidably set on the circular tube 3, under the action of gravity, the lifting plate 6 slides down along the circular tube 3 and the lower part of the lifting plate 6 is embedded in the water. The lifting plate 6 increases the resistance of the float 8 to move in all directions in the water, making the float 8 more stable and reducing the occurrence of large displacement of the float 8 on the water surface caused by external factors.

[0029] In addition, since the aeration pipe 18 is located directly below the floating plate 8, and the lifting plate 6 is located around the aeration pipe 18, the bubbles generated during aeration will impact outward from the floating plate 8 as the center, which further increases the resistance of the floating plate 8 to move in all directions in the water, making the entire device tend to be stationary and eliminating the need for additional chains for fixation, making it convenient to use.

[0030] Furthermore, a controller 5 is fixedly installed on the inner wall of the mounting groove 9, and an auxiliary component 23 is fixedly installed at the bottom of the floating plate 8. The auxiliary component 23 is conical, and an auxiliary groove 26 is opened at the top of the auxiliary component 23. A motor 17 is fixedly installed inside the auxiliary groove 26. The output end of the motor 17 passes through the auxiliary component 23, and agitator plates 2 are symmetrically installed at equal intervals on the output end of the motor 17. A rotating groove 10 is symmetrically opened at the bottom of the floating plate 8. The rotating groove 10 is located above the agitator plates 2. A bearing 22 is fixedly installed on the output end of the motor 17. The bearing 22 is used to fill the gap between the output end of the motor 17 and the auxiliary component 23. A cover plate 12 is also fixedly installed at the top of the inner wall of the mounting groove 9. The cover plate 12 is used to seal the mounting groove 9. Aeration holes 27 are symmetrically opened at the top of the auxiliary component 23. The aeration holes 27 are located on both sides of the auxiliary groove 26 and are located directly below the second three-way valve 14. An aeration pipe 18 passes through the interior of the aeration holes 27.

[0031] Please refer to Figures 1-3 , Figure 5 and Figure 8 When the device is in use, the user can send a signal to the controller 5 via remote control. The controller 5 controls the speed difference between the two ends of the motor 17, which drives the agitator 2 to rotate. The agitator 2 stirs the surface of the sewage, thereby achieving the purpose of surface aeration and improving the aeration effect. While performing surface aeration, the thrust of the agitation can also move the entire device on the water surface. After reaching the predetermined position, the rotation stops, thereby adjusting the aeration position. At the same time, the installed cover plate 12 and bearing 22 ensure that the aerator 4 and the motor 17 do not come into contact with the sewage, ensuring the normal use of the equipment.

[0032] Furthermore, the bottom of the auxiliary component 23 is provided with an assembly groove 28, which is located directly below the motor 17. A water quality detector 16 is fixedly installed inside the assembly groove 28. The thickness of the water quality detector 16 is less than the depth of the assembly groove 28. The top of the circular tube 3 is symmetrically and evenly spaced with first three-way valves 1. The top of the inner wall of the sliding hole 24 is adhered and fixed with a first airbag 13. The first airbag 13 is connected to the circular tube 3 through the first three-way valve 1.

[0033] Please refer to Figures 1-3 and Figure 9Since the bottom of the auxiliary component 23 is fixedly equipped with a water quality detector 16, when moving the equipment, the water quality near the floating plate 8 can be detected in real time by the water quality detector 16, and the obtained data can be sent to the user through the controller 5 to assist the user in moving the floating plate 8 and to improve the aeration effect. At the same time, since the auxiliary component 23 is conical and the water quality detector 16 is located above the aeration pipe 18, the bubbles generated by the normal operation of the aeration pipe 18 will continuously impact the surface of the water quality detector 16, thereby eliminating the impact of particulate matter in the sewage on the water quality detector 16 when the floating plate 8 moves, thus facilitating the use.

[0034] In addition, before moving the floating disc 8, the first three-way valve 1 and the second three-way valve 14 can be remotely activated by the controller 5. This allows the airflow generated by the aerator 4 to pass through the three-way pipe 15, the second three-way valve 14, the connecting pipe 7, and the round pipe 3, and then be injected into the interior of the first air bladder 13 through the first three-way valve 1. This causes the first air bladder 13 to expand and push the lifting plate 6 upward, causing the lifting plate 6 to detach from the sewage. This reduces the moving resistance of the floating disc 8 and makes it easier for users to quickly move the floating disc 8 to adjust the aeration position.

[0035] Furthermore, a second airbag 21 is fixedly installed on the inner wall of the connecting pipe 7. The second airbag 21 has an annular structure and is located between the floating plate 8 and the circular pipe 3. Mounting holes 20 are symmetrically opened at equal intervals on the surface of the connecting pipe 7. A nozzle 11 is fixedly installed inside the mounting hole 20. The nozzle 11 extends into the interior of the second airbag 21 through the mounting hole 20. The interior of the second airbag 21 is filled with defoaming agent. A sealing plug 19 is also sealed inside the mounting hole 20. The sealing plug 19 is located directly above the second airbag 21.

[0036] Please refer to Figures 1-3 and Figure 7 During aeration, since the equipment is not moving, the first three-way valve 1 is not open. The controller 5 can periodically adjust the second three-way valve 14, so that the airflow generated by the aerator 4 is injected into the interior of the connecting pipe 7 through the three-way pipe 15 and the second three-way valve 14. At this time, the air pressure inside the connecting pipe 7 and the round pipe 3 gradually increases, which in turn squeezes the second air bladder 21 inside the connecting pipe 7, causing the volume of the second air bladder 21 to gradually shrink. This causes the defoaming agent inside the second air bladder 21 to be sprayed out through the nozzle 11 under pressure, achieving the effect of removing foam. Since most of the foam is blocked by the lifting plate 6 when it rises, most of the foam generated by aeration gathers on the water surface between the lifting plate 6 and the floating plate 8, thereby increasing the defoaming effect of the defoaming agent.

[0037] In addition, during maintenance, the mounting hole 20 can be opened by rotating the sealing plug 19 to add defoaming agent, which facilitates maintenance and use.

[0038] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
