[0027] It should be noted that the ozone generator is divided into two parts, a base 1 and an ozone generating device 7. After the ozone generator is used, the base 1 and the ozone generating device 7 can be separated to facilitate detection of the inside of the base 1 and avoid blockage when sewage is treated inside the base 1. The two sewage treatment chambers 2 are used in turn, and the ozone generating device 7 alternately inputs ozone into the two sewage treatment chambers 2, which is convenient for treating the sewage treatment chambers 2. The sealing gasket 3 is stuck in the groove at the top of the base 1. When the ozone generating device 7 is placed on the base 1, ozone leakage is avoided inside. The bottom plate 4 and the top The plate 6 is welded to the base 1 and the ozone generating device 7 respectively. Under the action of the electric telescopic rod 5, the ozone generating device 7 can be lifted up. Two annular threaded grooves 9 are provided in the two sewage treatment chambers 2, which are adapted to the size of the threaded ring 10. The filter screen 11 is installed inside the sewage treatment chamber 2 by means of the threaded ring 10. When the sewage is treated, some floating objects generated can be filtered out. The connecting pipe 2 13 transports the sewage from the two ends of the connecting pipe 1 12 to the two sewage treatment chambers 2 respectively. The connecting pipe 3 15 can discharge the sediment processed in the sewage treatment chamber 2.

[0028] In the present application, a motor 17 is fixedly mounted on one side of the bottom of the base 1, and rotating shafts 18 are provided on both sides of the bottom of the base 1. The top ends of the two rotating shafts 18 penetrate the base 1 and extend to the interiors of the two sewage treatment chambers 2 respectively. One end of the output shaft of the motor 17 is fixedly mounted on the bottom end of one of the rotating shafts 18 through a coupling.

[0029] It should be noted that the motor 17 and the electric telescopic rod 5 are both connected to an external power supply through a power cord, and the two rotating shafts 18 extend into the sewage treatment chamber 2 from the holes at the bottom of the sewage treatment chamber 2, and there is a sealing ring between the rotating shafts 18 and the sewage treatment chamber 2 to ensure the sealing of the interior of the sewage treatment chamber 2.

[0030] In the present application, a pulley 19 is fixedly installed on the surface of the two rotating shafts 18 and located at the bottom of the base 1. The two pulleys 19 are connected by a belt 20. The top ends of the two rotating shafts 18 are fixedly connected with a stirring member 21. A scraper 22 is fixedly connected on the surface of the two rotating shafts 18 and located on one side of the stirring member 21.

[0031] It should be noted that the belt 20 is sleeved between the two pulleys 19. Under the drive of the motor 17, the two rotating shafts 18 can be driven to rotate in the same direction at the same time. When the rotating shaft 18 rotates, the stirring member 21 can stir the sewage inside the sewage treatment chamber 2. When the ozone is then discharged into the sewage treatment chamber 2, the combination and reaction of the sewage and ozone are accelerated. At the same time, when the scraper 22 rotates with the rotating shaft 18, the side surface can contact the inner wall of the sewage treatment chamber 2 to clean up the impurities adhering to the inner wall of the sewage treatment chamber 2.

[0032] In the present application, connecting pipes 23 are fixedly connected to both sides of the bottom of the ozone generating device 7, and the bottom ends of the two connecting pipes 23 extend to the interior of the two sewage treatment chambers 2 respectively, and the bottom ends of the two connecting pipes 23 are evenly and fixedly connected with multiple branch pipes 24.

[0033] It should be noted that the two connecting pipes four 23 are connected inside the ozone generating device 7. Under the action of the internal control valve, ozone can be discharged through the connecting pipe four 23 on one side. The branch pipes one 24 are welded together with the connecting pipe four 23, and the branch pipes one 24 are dispersed to mix with the sewage more quickly and evenly.

[0034] In the present application, an air intake dustproof net 25 is fixedly installed on the back of the ozone generating device 7, and support seats 26 are fixedly connected to the back of the ozone generating device 7 and on both sides of the air intake dustproof net 25. A sliding rod 27 is fixedly connected between the upper and lower support seats 26, and springs 28 are provided on the surfaces of the two sliding rods 27.

[0035] In the present application, a connecting plate 29 is fixedly connected to the surfaces of the two sliding rods 27 and at the top ends of the two springs 28, a scraper plate 2 30 is fixedly connected to the middle of one side of the connecting plate 29, and a water collecting tank 31 is fixedly connected to one end of the connecting plate 29, and a drainage hole 32 is provided at the bottom of the water collecting tank 31.

[0036] It should be noted that the air required in the ozone generating device 7 enters the inside of the ozone generating device 7 through the air inlet dustproof net 25, and the air inlet dustproof net 25 filters the air entering. Four support seats 26 are welded to the outside of the ozone generating device 7 to provide support for the two slide bars 27. The bottom ends of the two springs 28 are clamped together with the two support seats 26 at the bottom, and the top ends are clamped together with the connecting plate 29. They are compression springs with good elasticity. The scraper 2 30 is installed on one side of the connecting plate 29 by screws, and the scraper 2 30 can be connected with the air inlet dustproof net 25. When it moves up and down, it cleans up the dust and lint filtered on the surface of the air intake dustproof net 25. The water collecting tank 31 is welded to one end of the connecting plate 29, and the water collecting tank 31 is made of transparent acrylic material. The drainage hole 32 at the bottom is small. The sewage collected in the water collecting tank 31 can drip slowly from the drainage hole 32, and the treated sewage is stored in the transparent acrylic water collecting tank 31. The color and clarity of the sewage in the water collecting tank 31 can be observed by the camera or the staff, so as to judge the treatment effect of the ozone generator on the sewage.

[0037] In the present application, a water collecting tank 2 33 is fixedly connected to the back of the ozone generating device 7 and located at the bottom of the water collecting tank 1 31 . The water collecting tank 2 33 is located directly below the bottom of the water collecting tank 1 31 , and a drain pipe 2 34 is fixedly connected to one side of the water collecting tank 2 33 .

[0038] In the present application, a branch pipe 2 35 is fixedly connected to the top of one of the drainage pipes 1 8 , and a rubber hose 36 is fixedly connected to the top of the branch pipe 2 35 .

[0039] It should be noted that the water collecting tank 2 33 is fixed on the outside of the ozone generating device 7 and is at the bottom of the water collecting tank 1 31. It can collect the sewage overflowing and dripping from the water collecting tank 1 31, and then discharge it outward through the drain pipe 2 34 for further treatment. Part of the sewage in the drain pipe 1 8 is transported to the branch pipe 2 35 through the booster pump, and then discharged into the water collecting tank 1 31 through the rubber hose 36. When the electric telescopic rod 5 controls the ozone generating device 7 to move upward, the water collecting tank 1 31 can be deformed after contacting the rubber hose 36, which will not affect the upward movement of the ozone generating device 7.

[0040] The present invention is specifically implemented:

[0041] In the present invention, when the ozone generator is used to treat sewage, the external air enters the ozone generating device 7 through the air inlet dustproof net 25 to generate ozone. Then, when the sewage in a sewage treatment chamber 2 reaches a certain depth, the ozone can be discharged into the sewage through the connecting pipe 4 23 and the branch pipe 1 24 on one side. In the process of ozone generation, the sewage also enters the corresponding sewage treatment chamber 2 through the connecting pipe 2 13 and one end of the connecting pipe 1 12.

[0042] When ozone is discharged into the sewage treatment chamber 2 and mixed with the sewage, the motor 17 is also turned on, driving one rotating shaft 18 to rotate, and under the cooperation of the pulley 19 and the belt 20, driving the other rotating shaft 18 to rotate, the two rotating shafts 18 rotate together, and the stirring member 21 at the top thereof rotates inside the two sewage treatment chambers 2. After the sewage is stirred by the stirring member 21, it mixes with the ozone more quickly and evenly, thereby improving the sewage treatment effect;

[0043] The sewage in the sewage treatment chamber 2 is increasing, and when the sewage after the reaction with ozone overflows to the height of the drain pipe 8, the sewage can be discharged outward through the drain pipe 8, and when the sewage is discharged outward, the suspended matter on the upper layer of the sewage can also be filtered down by the filter screen 11, so as to avoid the suspended matter from clogging inside the drain pipe 8 when being discharged outward through the drain pipe 8, thereby affecting the normal discharge of sewage later;

[0044] After a sewage treatment chamber 2 has treated the sewage for a period of time, a control valve 14 on the connecting pipe 12 is opened, and another control valve 14 is closed, and the connecting pipe 12 and the connecting pipe 2 13 cooperate to discharge the sewage into another sewage treatment chamber 2, and at the same time, the ozone generated in the ozone generating device 7 can also be discharged through another connecting pipe 4 23, and the sewage is continuously treated in this sewage treatment chamber 2, and the impurities that have been filtered out of the sewage treatment chamber 2 used before can be discharged through the connecting pipe 3 15 at the bottom, so as to ensure the cleanliness of the interior of this sewage treatment chamber 2, and at the same time, it is also avoided that too many impurities are filtered out of the sewage treatment chamber 2, which affects the treatment effect of the sewage;

[0045] When a sewage treatment chamber 2 is used to treat sewage, the sewage is discharged through a drain pipe 8. During this process, the sewage can be transported upward through a branch pipe 35 and a rubber hose 36. When the sewage drips downward into a water collecting tank 31 through the rubber hose 36, the water collecting tank 31 is slowly filled. During this process, the weight of the water collecting tank 31 gradually increases, and the spring 28 can be pressed downward, thereby driving the connecting plate 29 and the scraper 2 30 to move downward together, cleaning the surface of the air intake dustproof net 25, ensuring the cleanliness of the surface of the air intake dustproof net 25, so that the external air can normally enter the ozone generating device 7, and then the sewage will be collected in the water collecting tank 31. When the ozone generator is filled and overflows, the sewage can drip into the water collecting tank 33 and be discharged by the drainage pipe 34. When the ozone generator is used continuously and the amount of sewage impurities in the water collecting tank 31 increases in the later stage, the ozone generator can be turned off and the ozone generator can be internally treated and repaired. When the sewage treatment chamber 2 is replaced to treat the sewage, the branch pipe 35 no longer delivers water to the water collecting tank 31. The sewage in the water collecting tank 31 can slowly drip into the water collecting tank 33 through the drainage hole 32. The weight of the water collecting tank 31 is reduced, and the spring 28 can support it upward again, so that the surface of the air intake dust screen 25 can be cleaned again.

[0046] When the ozone generator is being inspected and repaired, the electric telescopic rod 5 can be controlled to extend upward to lift the ozone generating device 7. Then the staff can rotate the threaded ring 10 to rotate the filter 11 down from the annular threaded groove 9 for cleaning or replacement. The interior of the sewage treatment chamber 2 is constantly rubbed by the scraper 22, and the staff only needs to use some tools with strong friction to clean it.

[0047] By providing two sewage treatment chambers 2 on the base 1, and two connecting pipes 23 are also provided at the bottom of the ozone generating device 7, sewage enters the two sewage treatment chambers 2 through the connecting pipe 1 12 and the connecting pipe 2 13 respectively, and the sewage is treated alternately, the ozone generator can work continuously, and the inside of the sewage treatment chamber 2 can also be cleaned at the same time, so as to improve the cleanliness of the inside of the sewage treatment chamber 2, and the sewage treatment is faster and the treatment effect is better;

[0048] By arranging a rotating shaft 18 inside the sewage treatment chamber 2, when the motor 17 drives the rotating shaft 18 to rotate, the stirring member 21 can be driven to stir the sewage inside, so that the ozone and sewage are mixed more quickly and more evenly. At the same time, when the rotating shaft 18 rotates, the scraper 22 can also rotate together to scrape and clean the inner wall of the sewage treatment chamber 2, so as to prevent the impurities and the like from being adhered to the inner wall of the sewage treatment chamber 2 during sewage treatment, resulting in a decrease in the cleanliness of the sewage treatment chamber 2, thereby indirectly affecting the sewage treatment effect. At the same time, the filter screen 11 is installed in the annular thread groove 9 through the threaded ring 10, and can filter the discharged sewage, so as to prevent the impurities and suspended matter generated during sewage treatment from entering the drain pipe 8 with the sewage, and then causing the drain pipe 8 to be blocked, thereby affecting the transportation of sewage;

[0049] By installing a branch pipe 2 35 and a rubber hose 36 on one of the drain pipes 8, and arranging a slide bar 27, a spring 28, a connecting plate 29, a scraper 2 30 and a water collecting box 1 31 on the side of the air intake dustproof net 25 on the back side of the ozone generating device 7, the water collecting box 1 31 collects the treated sewage, thereby increasing the weight, pressing the spring 28 downward, and the scraper 2 30 can move downward to treat the air intake dustproof net 25. Later, when the sewage inside the water collecting box 1 31 is discharged through the drain hole 32 and the weight is reduced, the scraper 2 30 and others move upward under the action of the spring 28, and the surface of the air intake dustproof net 25 can be treated again to avoid clogging of the air intake dustproof net 25 due to dust and impurities, affecting the air supply to the inside of the ozone generating device 7, and further affecting the normal production of ozone.
