Description

Technical Field

[0001] The present invention relates to the technical field of sewage treatment, and in particular to energy-saving and environmentally friendly water treatment equipment and a treatment process. Background Art

[0002] In the water treatment process, sewage is first smoothly introduced into the sewage pool. This process uses a low-power, high-efficiency water pump. Its optimized hydraulic design significantly reduces energy consumption when transporting sewage. At the same time, the ozone machine continues to operate and continuously produces ozone. The ozone machine uses advanced energy-saving technology. Through the intelligent control system, it accurately matches the amount of ozone produced and the sewage treatment needs, avoiding energy waste caused by excessive ozone production. The generated ozone is accurately transported to the sewage pool through a special pipeline system. Relying on the powerful oxidation characteristics of ozone, it chemically reacts with various pollutants in the sewage, thereby achieving sewage purification, effectively reducing the pollutant content and improving water quality.

[0003] In water treatment, when ozone is introduced into sewage using an aerator, the bubbles generated after the aerator is running are too dense, making it difficult for the ozone to be fully and evenly mixed with the sewage in a limited space and time. At the same time, a large amount of ozone that has not been mixed with the sewage will drift directly into the surrounding air, causing ozone to be wasted on the one hand, and on the other hand, the drifting ozone will also pollute the surrounding environment and pose a potential threat to the ecological environment and human health. There is a need for further optimization in the full mixing of ozone and sewage. Therefore, the present application provides an energy-saving water treatment and environmental protection equipment and a treatment process to meet the needs. Summary of the invention

[0004] The technical problem to be solved by the present invention is to provide an energy-saving water treatment and environmental protection equipment and a treatment process to solve the problem of low mixing efficiency of ozone and sewage.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] An energy-saving water treatment and environmental protection equipment and treatment process, including an ozone generator and a sewage pool, and also including:

[0007] Mobile aeration structure, the mobile aeration structure includes a moving shell arranged inside the sewage tank. Inner threaded sleeves are fixed at both opposite ends of the moving shell. Mounting seats are fixed on both opposite sides of the sewage tank. A servo motor is fixed on the mounting seat. The output shaft of the servo motor movably penetrates through the mounting seat and is fixed with a screw rod. The inner threaded sleeve is threadedly sleeved on the surface of the screw rod. Two rotating motors are fixed on the top of the moving shell. The output ends of the two rotating motors movably penetrate through the moving shell and are fixed with connecting rods. A round tube is fixed at the bottom of the connecting rod. Air inlet holes, first air outlet holes and a plurality of second air outlet holes are formed on the surface of the round tube. The plurality of second air outlet holes are spirally distributed. The air inlet hole is located above the second air outlet hole, and the second air outlet hole is located above the first air outlet hole. A tee pipe is fixedly penetrated through the bottom of the moving shell. The tee pipe is rotatably connected to both round tubes. The tee pipe is communicated with the round tube through the air inlet hole. The tee pipe is connected to an ozone generator through a hose;

[0008] During sewage treatment, the servo motor drives the screw rod to rotate. The screw rod drives the moving shell to reciprocate on the sewage tank through the inner threaded sleeve. The moving shell can drive the round tube to reciprocate in the sewage tank. At the same time, the rotating motor drives the round tube to rotate through the connecting rod, so that ozone is ejected at different depths and positions at different speeds and directions.

[0009] Preferably, rotating plates are rotatably connected to both opposite sides of the moving shell. Vertical parts are arranged at the bottoms of the two rotating plates.

[0010] Preferably, a plurality of hollow floating blocks are fixed on the opposite sides of the two rotating plates. The distances between the plurality of hollow floating blocks are the same.

[0011] Preferably, a guiding surface is arranged on the side surface of the hollow floating block for guiding the discharge of floating foam.

[0012] Preferably, a fixing sleeve is fixed on the surface of the round tube. A spring is fixed at the bottom of the inner wall of the fixing sleeve. A ring is fixed at the top of the spring. The ring is movably sleeved on the surface of the round tube. The outer surface of the round tube is movably connected to the inner wall of the fixing sleeve. A spiral strip is fixed at the top of the ring. A bearing is movably sleeved on the surface of the round tube. The top of the spiral strip is fixed at the bottom of the inner ring of the bearing. An inclined rod is fixed on the outer ring surface of the bearing. The inclined rod abuts against the rotating plate. A guiding rod is fixed on the outer ring of the bearing. A guiding sleeve is movably sleeved on the surface of the guiding rod. The guiding sleeve is fixed at the bottom of the moving shell. When the rotating plate rotates, it can drive the inclined rod to move downward. When the inclined rod moves downward, it can drive the spiral strip to move downward through the bearing. During the downward movement of the spiral strip, the exposed area of the second air outlet hole gradually increases.

[0013] Preferably, the first air outlet hole is inclined.

[0014] Preferably, cleaning plates are rotatably connected to the tops of both opposite ends of the sewage tank.

[0015] Preferably, a protrusion is provided at the top edge of the cleaning plate.

[0016] Preferably, storage boxes are fixed at both ends of the sewage tank, and a sewage discharge port is provided at the bottom of the storage box.

[0017] An energy-saving water treatment process is applied to the above-mentioned energy-saving water treatment and environmental protection equipment, including the following processes:

[0018] S1. Supply sewage into the sewage tank;

[0019] S2. Generate ozone through an ozone generator and fully mix the ozone with the sewage through a mobile aeration structure;

[0020] S3. Drain the sewage in the sewage tank.

[0021] Compared with the prior art, the present invention has at least the following beneficial effects:

[0022] In the above solution, by setting the servo motor, the moving shell and the round tube, the round tube can not only move left and right in the sewage tank, but also rotate itself. Cooperating with the inclined air outlet one and the helically distributed air outlet two, the ozone is ejected from different depths and positions at different speeds and directions, greatly improving the mixing efficiency of the ozone and the sewage, avoiding the problem that a large amount of ozone gushes out at the same position at one time, resulting in insufficient mixing and wasteful dispersion, reducing the ineffective loss of ozone, and thus reducing the energy consumption of ozone preparation and achieving energy saving and efficiency improvement.

[0023] By setting the spiral strip and the rotating plate, the rotation speed of the servo motor is adjusted according to the sewage concentration. When the sewage concentration is high, the speed is increased, so that the spiral strip descends greatly, and the exposed area of the air outlet two is large, thereby increasing the air output of the air outlet two; when the concentration is low, the speed is reduced, the spiral strip descends less, and the exposed area of the air outlet two is small, reducing the ozone ejection amount, accurately adapting to the treatment requirements, avoiding ozone waste, and further enhancing the energy-saving performance.

[0024] Due to the inclined air outlet one, the air outlet one can strongly blow up the impurities deposited at the bottom of the sewage tank, enabling the ozone to fully contact the pollutants, reducing the treatment dead corners in the sewage tank, ensuring more thorough sewage purification, and improving the overall treatment quality.

[0025] By setting the cleaning plate, the rotating plate and the hollow floating block cooperate. The foam generated by aeration can flow out along the guiding surface, and the rotating plate facing the sewage can also gather the foam to one side; when the rotating plate contacts the cleaning plate, the foam can be shoveled up by the cleaning plate and flow into the storage box. The protrusion on the cleaning plate effectively prevents the foam from overflowing, ensuring efficient and thorough foam cleaning and maintaining the smoothness of the treatment process.

[0041] As Figures 1-8 shown, an embodiment of the present invention provides an energy-saving water treatment environmental protection device and treatment process, including an ozone machine 1 and a sewage tank 2, and further including:

[0042] A mobile aeration structure 7, the mobile aeration structure 7 includes a mobile shell 8 arranged inside the sewage tank 2. Inner threaded sleeves 6 are fixed at both opposite ends of the mobile shell 8. Mounting seats 3 are fixed on both opposite sides of the sewage tank 2. A servo motor 4 is fixed on the mounting seat 3. The output shaft of the servo motor 4 movably penetrates through the mounting seat 3 and is fixed with a screw rod 5. The inner threaded sleeve 6 is threadedly sleeved on the surface of the screw rod 5. Two rotating motors 11 are fixed on the top of the mobile shell 8. The output ends of the two rotating motors 11 movably penetrate through the mobile shell 8 and are fixed with connecting rods 12. A circular tube 13 is fixed at the bottom of the connecting rod 12. Air inlet holes 16, first air outlet holes 14 and a plurality of second air outlet holes 15 are formed on the surface of the circular tube 13. The plurality of second air outlet holes 15 are spirally distributed. The air inlet hole 16 is located above the second air outlet holes 15, and the second air outlet holes 15 are located above the first air outlet holes 14. A tee pipe 25 is fixedly penetrated through the bottom of the mobile shell 8. The tee pipe 25 is rotatably connected to both circular tubes 13. The tee pipe 25 is communicated with the circular tube 13 through the air inlet hole 16. The tee pipe 25 is connected to the ozone machine 1 through a hose;

[0043] During sewage treatment, the servo motor 4 drives the screw 5 to rotate. The screw 5 drives the moving shell 8 to reciprocate on the sewage tank 2 through the internal thread sleeve 6. The moving shell 8 can drive the circular pipe 13 to reciprocate in the sewage tank 2. At the same time, the rotating motor 11 drives the circular pipe 13 to rotate self - sufficiently through the connecting rod 12, so that ozone is ejected at different speeds and directions at different depths and positions;

[0044] The internal thread sleeves 6 fixed at both ends of the moving shell 8 cooperate with the screw 5 on the mounting seat 3. The mounting seat 3 is fixed on both sides of the sewage tank 2 to provide support for the entire moving system. The servo motor 4 drives the screw 5 to rotate. Due to the threaded connection between the internal thread sleeve 6 and the screw 5, when the screw 5 rotates, it can accurately drive the moving shell 8 to reciprocate on the sewage tank 2, thereby driving the circular pipe 13 to change its position, realizing the aeration treatment of sewage in different areas, expanding the range of ozone action, and avoiding uneven local treatment. The two rotating motors 11 on the top of the moving shell 8 drive the connecting rod 12 to rotate, and then the circular pipe 13 rotates self - sufficiently. This combination of movement and self - rotation enables ozone to be ejected at different speeds and directions at different depths and positions in the sewage, greatly improving the mixing efficiency of ozone and sewage, reducing ozone waste caused by uneven mixing, saving energy and enhancing the treatment effect. The air inlet holes 16 opened on the surface of the circular pipe 13 are used to receive ozone from the tee pipe 25. The tee pipe 25 is connected to the ozone generator 1 through a hose to ensure stable ozone supply. The air outlet holes one 14 and the helically distributed air outlet holes two 15 at different positions on the circular pipe 13 can flexibly adjust the ejection state of ozone according to requirements.

[0045] As Figure 3 and Figure 4 shown, in this embodiment, rotating plates 9 are rotatably connected to opposite sides of the moving shell 8. Vertical parts 10 are provided at the bottoms of the two rotating plates 9. Especially when the sewage concentration is high, the servo motor 4 increases the rotation speed, the resistance between the rotating plate 9 and the sewage increases, and the rotating plate 9 facing the sewage direction rotates downward. The vertical part 10 increases the contact area with the sewage, not only making it easier for the rotating plate 9 to rotate itself, but also further strengthening the stirring effect on the sewage, promoting more violent sewage flow, helping ozone to diffuse better, increasing the contact probability with pollutants, and accelerating the treatment process. At the same time, the rotation of the rotating plate 9 is also related to a series of subsequent adaptive adjustment actions, laying a foundation for the flexible operation of the entire device according to the sewage conditions.

[0046] As Figure 4As shown, in this embodiment, a number of hollow floating blocks 26 are fixed to the opposite sides of the two rotating plates 9. The spacing between the a number of hollow floating blocks 26 is the same. During aeration, the foam is likely to accumulate on the water surface. The hollow floating blocks 26 float on the sewage water surface, and the guiding surface 27 provided on the side thereof can guide the foam to be discharged along a specific direction, preventing the foam from accumulating in large quantities on the surface of the sewage tank 2, reducing the interference of the foam on the subsequent treatment links, maintaining the smoothness of the treatment process, and also being beneficial to improving the overall stability and reliability of the equipment and reducing the maintenance cost.

[0047] As Figure 4 shown, in this embodiment, a guiding surface 27 is provided on the side of the hollow floating block 26 for guiding the discharge of the foam. After the foam is generated, under the action of water flow and buoyancy, it will naturally flow along the guiding surface 27 to achieve preliminary separation and diversion of the foam, preventing the foam from accumulating at the bottom of the rotating plate 9, ensuring the continuous and efficient progress of sewage treatment, and at the same time reducing the burden of subsequent foam cleaning.

[0048] As Figures 4-7As shown, in this embodiment, a fixing sleeve 22 is fixed on the surface of the circular tube 13, a spring 23 is fixed to the bottom of the inner wall of the fixing sleeve 22, a ring 24 is fixed on the top of the spring 23, the ring 24 is movably sleeved on the surface of the circular tube 13, the outer surface of the circular tube 13 is movably connected to the inner wall of the fixing sleeve 22, a spiral strip 21 is fixed on the top of the ring 24, a bearing 17 is movably sleeved on the surface of the circular tube 13, the top of the spiral strip 21 is fixed to the bottom of the inner ring of the bearing 17, and the outer ring surface of the bearing 17 is fixed with The inclined rod 18 is against the rotating plate 9, and the outer ring of the bearing 17 is fixed with a guide rod 19. The surface of the guide rod 19 is movably sleeved with a guide sleeve 20, and the guide sleeve 20 is fixed to the bottom of the moving shell 8. The rotating plate 9 rotates to drive the inclined rod 18 to move downward. The downward movement of the inclined rod 18 can drive the spiral strip 21 to move downward through the bearing 17. During the downward movement of the spiral strip 21, the exposed area of ​​the air outlet 15 gradually increases. When the rotating plate 9 rotates, the inclined rod 18 against it will Move downward, since the inclined rod 18 is fixed to the outer ring of the bearing 17, the bottom of the inner ring of the bearing 17 is fixed with a spiral strip 21, and the top of the spiral strip 21 is fixed to the surface of the round tube 13, the inclined rod 18 moves downward and can drive the spiral strip 21 to move downward through the bearing 17. In this process, the exposed area of ​​the second air outlet 15 gradually increases, which means that the ozone output volume gradually increases. When the sewage concentration is large and more ozone is required to participate in the reaction, the equipment can make adjustments to improve the sewage treatment efficiency and avoid incomplete treatment due to insufficient ozone supply; when the sewage concentration is low, the rotating plate 9 rotates with a small amplitude, the opening of the second air outlet 15 becomes smaller, and the ozone spray volume is reduced to prevent ozone waste, thereby realizing intelligent and energy-saving regulation according to the actual situation of sewage. At the same time, a convex block is provided on the surface of the ring 24, and a groove is provided on the inner wall of the fixed sleeve 22. The convex-convex cooperation of the convex block and the groove jointly ensures the stability of each component during the movement, avoids unnecessary shaking or dislocation, and ensures the accurate and reliable operation of the adjustment system.

[0049] like Figure 7 As shown, in this embodiment, the air outlet 14 is inclined. When ozone is discharged from the air outlet 14, it can impact the bottom of the sewage pool 2 at a certain angle, and blow up the impurities deposited at the bottom, so that the bottom impurities that were originally difficult to contact with ozone are fully exposed to the ozone environment, allowing ozone to contact the pollutants in the sewage in all directions, reducing dead corners in the sewage pool 2, greatly improving the degree of sewage purification, making the treatment more thorough, and improving the overall treatment quality.

[0050] like Figures 1-3As shown in the figure, in this embodiment, cleaning plates 28 are rotatably connected to the tops of opposite ends of the sewage tank 2. During the operation of the equipment, the foam generated by aeration is gathered by the rotating plate 9 and guided to the cleaning plates 28. The special design of the cleaning plates 28 enables them to rotate upward along the inclined surface of the rotating plate 9 until they are separated from the sewage. At this time, the moving housing 8 stays for a period of time, and the foam will be shoveled up and flow into the storage bins 29 at both ends along the cleaning plates 28, realizing the efficient cleaning of the foam, avoiding the circulation of the foam in the sewage tank 2, ensuring the cleanliness of the treatment environment, facilitating the stable progress of subsequent treatment processes, and also reducing the corrosion risk of the foam to the equipment components.

[0051] As Figure 2 shown in the figure, in this embodiment, protrusions are provided at the top edges of the cleaning plates 28. When the foam flows along the cleaning plates 28, the protrusions can effectively prevent the foam from flowing to both sides, ensuring that the foam can only flow into the collection box along the predetermined path, improving the accuracy and integrity of foam collection, preventing the foam from falling back into the sewage tank 2, maintaining the cleanliness of the sewage tank 2 and the entire treatment system, reducing the risk of secondary pollution, and ensuring the orderly progress of the sewage treatment work.

[0052] As Figures 1-3 shown in the figure, in this embodiment, storage bins 29 are fixed to both ends of the sewage tank 2. A sewage discharge port is provided at the bottom of the storage bins 29. The storage bins 29 are used to collect the foam conveyed by the cleaning plates 28. The sewage discharge port facilitates the periodic discharge of the accumulated foam for subsequent treatment, avoiding the accumulation and deterioration of the foam in the storage bins 29, maintaining the accommodation capacity of the storage bins 29, ensuring the long-term stable operation of the foam cleaning link, providing strong support for the continuous and efficient operation of the sewage treatment equipment. At the same time, the reasonable setting of the storage bins 29 also facilitates the overall maintenance and management of the equipment, reducing the operation and maintenance costs.

[0053] An energy-saving water treatment process is applied to the above-mentioned energy-saving water treatment and environmental protection equipment, including the following processes:

[0054] S1. Supply sewage into the sewage tank 2;

[0055] S2. Generate ozone through the ozone generator 1 and fully mix the ozone with the sewage through the mobile aeration structure 7;

[0056] S3. Drain the sewage in the sewage tank 2.

[0057] Working principle:

[0058] First, the sewage is introduced into the sewage tank 2, and at the same time, oxygen is introduced into the ozone generator 1;

[0059] The ozone generator 1 makes oxygen into ozone, and the generated ozone is transported through a hose. To prevent the hose from contacting and lapping with the sewage, a hose winding and unwinding device is provided on the side of the sewage tank 2 for winding and unwinding the hose, and the ozone is finally sent into the tee pipe 25;

[0060] After the ozone enters the tee pipe 25, it enters the circular pipe 13 through the air inlet hole 16. At the same time, the servo motor 4 on the mounting seat 3 starts to drive the screw rod 5 to rotate reciprocally. The screw rod 5 drives the internally threaded sleeve 6 sleeved with threads to move synchronously reciprocally. The internally threaded sleeve 6 further drives the moving shell 8 to move reciprocally on the sewage tank 2. During the movement of the moving shell 8, the two rotating motors 11 on its top drive the connecting rod 12 to rotate, and the connecting rod 12 drives the circular pipe 13 to rotate. In this way, the circular pipe 13 can not only move left and right in the sewage tank 2 but also rotate itself;

[0061] When the circular pipe 13 rotates, the ozone is discharged from the inclined air outlet one 14 and several spiral-distributed air outlets two 15. The ozone discharged from the air outlet one 14 impacts the bottom of the sewage tank 2, blowing up the deposited impurities, making the ozone fully contact with the pollutants, and reducing the treatment dead angle; the spiral-distributed air outlets two 15 allow the ozone to be ejected at different speeds and directions at different depths and positions, greatly improving the mixing efficiency of the ozone and the sewage, avoiding ozone waste, and reducing energy consumption;

[0062] According to the different sewage concentrations, the rotation speed of the servo motor 4 is changed. When the sewage concentration is high, the rotation speed of the servo motor 4 is increased, so that the resistance between the rotating plate 9 and the sewage increases. The rotating plate 9 facing the sewage direction rotates downward, and the vertical part 10 at the bottom of the rotating plate 9 increases the contact area with the sewage, making it easier to rotate. The rotation of the rotating plate 9 drives the inclined rod 18 to move downward, and the inclined rod 18 drives the bearing 17 and the spiral strip 21 to move downward. During the process, the exposed area of the air outlet two 15 gradually increases, and the ozone output gradually increases, improving the sewage treatment efficiency; at the same time, the spiral strip 21 drives the ring 24 to move downward, compressing the spring 23. When the sewage concentration is low, the rotation speed of the servo motor 4 decreases, the downward rotation amplitude of the rotating plate 9 decreases, the opening of the air outlet two 15 becomes smaller, and the ozone ejection amount decreases, avoiding waste. During this process, the guide rod 19 and the guide sleeve 20 guide the movement of the bearing 17, and the ring 24 and the fixed sleeve 22 are matched through a concave-convex structure to prevent the components from rotating and ensure stable operation;

[0063] When the moving shell 8 moves, one rotating plate 9 rotates downward, and the other rotating plate 9 rotates upward under the action of the sewage resistance. The hollow floating block 26 at the bottom of the rotating plate 9 floats on the sewage surface, and the foam generated by aeration flows out along the guiding surface 27 on the side of the hollow floating block 26. The rotating plate 9 facing the sewage also gathers the foam to one side;

[0064] When the rotating plate 9 contacts the cleaning plates 28 added at the top of both ends of the sewage tank 2, the cleaning plates 28 rotate upward along the inclined surface of the rotating plate 9 until they are separated from the sewage. At this time, the moving housing 8 stays for a period of time, and the rotating plate 9 shovels up the accumulated floating foam. The floating foam flows into the storage boxes 29 at both ends along the cleaning plates 28. The protrusions at the top edge of the cleaning plates 28 prevent the floating foam from flowing to both sides, ensuring that the floating foam only flows into the collection box, realizing the efficient cleaning of the floating foam. After the cleaning is completed, the moving housing 8 moves in the reverse direction, and the cleaning plates 28 fall back to their original positions.
