Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ozone catalytic oxidation tower. Background Technology

[0002] Ozone catalytic oxidation tower belongs to the field of water treatment technology, specifically involving a wastewater treatment device based on advanced oxidation technology. This technology generates highly oxidizing hydroxyl radicals through the synergistic effect of ozone and catalyst, which efficiently decomposes recalcitrant organic pollutants in water. It is widely used in fields such as deep treatment of industrial wastewater, upgrading and renovation of municipal sewage, and drinking water purification.

[0003] Existing ozone catalytic oxidation towers use filters to remove impurities from the wastewater injected into the tower to ensure the effectiveness of ozone treatment. However, during the filtration process, impurities accumulate on the filters, which can easily clog them, reducing the wastewater flow and consequently decreasing the amount of wastewater the unit can process. This not only affects the unit's treatment efficiency but also its overall treatment effect.

[0004] A Chinese patent discloses a filterable ozone catalytic oxidation tower (authorization announcement number CN221894809U). This patented technology designs a self-cleaning mechanism consisting of a rotating shaft, blades, a cleaning brush, and a limiting disc. During the operation of the device, the filter screen filters impurities in the extracted and transported wastewater. At the same time, the impact force of the wastewater flow drives the blades to rotate. The blades then drive the cleaning brush to rotate on the surface of the filter screen through the rotating shaft. During the rotation, impurities attached to the surface of the filter screen can be cleaned, thereby effectively preventing impurities from clogging the filter screen, ensuring the wastewater flow rate and the amount of wastewater the device can process, and improving the treatment efficiency and effect of the device.

[0005] However, it has certain drawbacks: during long-term operation, the brush will continue to wear down, and the contact pressure between the brush and the filter screen will gradually weaken, resulting in a significant decrease in cleaning efficiency; the worn brush cannot adaptively compensate for displacement, and is prone to forming gaps with the filter screen, causing impurities to accumulate and clog the filter holes, seriously affecting the efficiency of sewage flow.

[0026] Ozone inlet pipe 4 is used for releasing pressurized ozone.

[0027] Wastewater outlet pipe 5 is used for discharging wastewater after catalytic oxidation;

[0029] The stirring rod 9 is used to stir the discharged wastewater and ozone to make them mix evenly;

[0030] Filter screen 10 is used to filter impurities in wastewater.

[0031] exist Figures 1-5In the middle section: A transparent plate 11 is fixedly connected to the front surface of the wastewater inlet pipe 3. A cleaning mechanism 12 is provided inside the filter screen 10. The cleaning mechanism 12 includes a slide tube 13, which is rotatably connected to the filter screen 10. An impeller 14 is fixedly connected to the right end of the slide tube 13, and the impeller 14 is located on the right side of the filter screen 10. A slide rod 15 is slidably connected inside the slide tube 13. A brush 16 is fixedly connected to the left end of the slide rod 15 and is attached to the left side surface of the filter screen 10. A fixing block 17 is fixedly connected inside the slide tube 13 to the right side of the slide rod 15. A spring 18 is fixedly connected to the left side surface of the fixing block 17, and the left end of the spring 18 is fixedly connected to the right end of the slide rod 15. Fixed rods 19 are fixedly connected to both the upper and lower sides of the left side surface of the spring 18. The fixed rods 19 are movably embedded inside the slide rod 15. An adjustment mechanism 20 is provided on the upper surface of the slide tube 13 to the left of the impeller 14. The adjustment mechanism 20 includes a connecting plate 21. The lower end of the connecting plate 21 is fixedly connected to the upper surface of the slide tube 13. A second motor 22 is fixedly connected to the front surface of the connecting plate 21. A connecting rod 23 is fixedly connected to the output end of the second motor 22. A connecting rope 24 is wound around the outside of the connecting rod 23. The connecting rope 24 movably passes through the upper surface of the slide tube 13 and the fixed block 17, and the connecting rope 24 movably passes through the spring 18. One end of the connecting rope 24 is fixedly connected to the right end of the slide rod 15.

[0032] The transparent plate 11 can be made of glass and is used to observe the inside of the wastewater inlet pipe 3;

[0033] The impeller 14 drives the slide tube 13 to rotate under the impact of the wastewater flow, thereby driving the brush 16 to clean the surface of the filter screen 10, so as to prevent the accumulation of impurities on the surface of the filter screen 10 and cause blockage, which would affect the normal flow of wastewater.

[0034] The slide tube 13 and the filter screen 10 can be rotatably connected by a bearing. The slide tube 13 is fixed in the inner ring of the bearing, and the outer ring of the bearing is fixed in the filter screen 10, thus forming a rotating state.

[0035] The front surface of the connecting plate 21 is located outside the motor 22 and a sealing cover can be installed according to actual needs;

[0036] Motor 22 is equipped with a brake, meaning that the motor shaft cannot rotate after power is cut off, and motor 22 is connected to the forward and reverse circuit;

[0037] Motor 22 is preferably a servo motor or a stepper motor, which can rotate a fixed angle each time it is started;

[0038] When the connecting rope 24 is wound up, it can pull the slide bar 15 to move it into the slide tube 13 (in this process, the spring 18 is compressed), so that the bristles of the brush 16 always stick to the filter screen 10. This avoids the situation where the bristles wear down during long-term use and cannot contact the filter screen 10, thus preventing effective cleaning. The condition of the brush 16 can be observed through the transparent plate 11.

[0039] The working principle of this utility model is as follows: When pressurized wastewater enters the tower body 1 through the wastewater inlet pipe 3, the water flow impacts the impeller 14, causing it to rotate and drive the slide tube 13 to rotate. This causes the brush 16, which is fixed to the left end of the slide rod 15, to perform circumferential scraping on the surface of the filter screen 10, filtering impurities and preventing clogging. When the brush 16 becomes worn and has poor contact with the filter screen 10, the motor 22 is started to wind up the connecting rope 24, pulling the slide rod 15 to the right within the slide tube 13 to compress the spring 18, so that the brush 16 can re-adhere tightly to the filter screen 10. At this time, the fixing rod 19 maintains the stability of the movement trajectory of the slide rod 15. At the same time, ozone is injected into the tower body 1 through the ozone inlet pipe 4, and the motor 8 drives the stirring rod 9 to fully mix the wastewater and ozone. After the mixture is catalytically oxidized by the catalytic packing 6, it is discharged from the wastewater outlet pipe 5. The operator can observe the cleaning status of the filter screen 10 in real time through the transparent plate 11.
