Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to an ozone dosing device for wastewater treatment. Background Technology

[0002] Ozone, an allotrope of oxygen, has strong oxidizing properties and can decompose organic matter that is difficult to destroy with general oxidants. Moreover, the reaction is safe, short-lived, and does not cause secondary pollution. It is commonly used in wastewater treatment in the environmental protection industry. When using it, ozone needs to be added to the wastewater tank to decompose the organic matter in the wastewater, which requires the use of ozone dosing devices for wastewater treatment.

[0003] Currently, wastewater treatment ponds on the market typically have ozone dosing devices installed at the perimeter, with the ozone delivered into the pond via pipes. Because these pipes cannot be adjusted during use, the treatment efficiency is low at locations far from the dosing device, and it's inconvenient to add or remove them later, making them unsuitable for wastewater treatment. Therefore, an ozone dosing device for wastewater treatment is proposed. Utility Model Content

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 This utility model provides a technical solution: an ozone dosing device for sewage treatment, including a floating platform 1, a motor 2, a water pump 3, an ejector 4, a connecting pipe 5, and an ozone generator 6. The upper surface of the floating platform 1 is fixedly connected to the motor 2 and the water pump 3. The output end of the motor 2 is connected to the water pump 3. The inlet of the water pump 3 is fixedly connected to a filter cylinder 7. The edge of the floating platform 1 is fixedly connected to an annularly distributed ejector 4. An adjusting seat 8 is provided at the connection between the ejector 4 and the floating platform 1. The inlet of the ejector 4 is connected to the outlet of the water pump 3. The surface of the ejector 4 is provided with an air intake pipe 9. The ozone generator 6 is connected to the air intake pipe 9 through a connecting pipe 5.

[0022] Further improvements include the fixed connection of several floats 10 to the lower surface of the floating platform 1, and the provision of a fixing ring 11 at the edge of the floating platform 1. By fixing several floats 10 to the lower surface of the floating platform 1, sufficient buoyancy can be provided to the floating platform 1. By fixing the fixing ring 11 at the edge of the floating platform 1, the floating platform 1 can be fixed, thereby improving the stability of the floating platform 1 during use.

[0023] In a further improvement, the surface of the filter cylinder 7 is provided with evenly distributed water inlet grooves 12, and the surface of the filter cylinder 7 is covered with a filter screen 13. By covering the surface of the filter cylinder 7 with a filter screen 13, it is convenient to filter the sewage sucked in by the water pump 3, avoid the water pump 3 from sucking in foreign objects and causing damage, and improve the safety of use.

[0024] In a further improvement, the bottom of the adjusting seat 8 is fixedly connected to a rotating column 14 and rotatably connected to the surface of the floating platform 1. The surface of the adjusting seat 8 is provided with several mounting holes 15. By providing a rotating column 14 at the bottom of the adjusting seat 8, it is convenient to adjust the angle of the adjusting seat 8, thereby changing the spray angle of the jet 4 to meet different usage requirements.

[0025] Specifically, the inner side of the adjusting seat 8 is provided with an adjusting ring 16 that is rotatably connected to the floating platform 1. A linkage rod 17 is provided at the connection between the adjusting seat 8 and the adjusting ring 16. The surface of the adjusting ring 16 is provided with evenly distributed limiting holes 18. The inside of the limiting holes 18 is provided with a limiting pin 19 that is inserted and connected to the floating platform 1. By providing a rotatable adjusting ring 16 on the inner side of the adjusting seat 8, and cooperating with the linkage rod 17, it is convenient to adjust multiple adjusting seats 8, thereby improving the ease of use.

[0026] In use, the float 10 is fixedly installed on the lower surface of the floating platform 1, allowing the platform 1 to float on the surface of the sewage. The platform 1 is then fixedly connected to the water surface using an iron chain. The ozone generator 6 is connected to the air inlet pipe on the surface of the jet injector 4 using a connecting pipe 5. After the motor 2 is powered on, it drives the water pump 3 to work, causing the water to flow through the jet injector 4 and spray outward, thereby drawing ozone gas into the jet injector 4. The water flow mixed with ozone is continuously sprayed out, which facilitates the purification of sewage. During use, the position and number of the dosing device can be adjusted according to the needs, improving the versatility and convenience of use.

[0027] This invention addresses the problem that existing wastewater treatment ponds typically have ozone dosing devices installed at their edges, with the ozone delivered into the pond via pipes. Because these pipes cannot be adjusted during use, the purification efficiency is low at locations far from the dosing device, and it's inconvenient to add or remove them later, leading to inconvenience in wastewater treatment. This invention utilizes a floating platform 1, an electric motor 2, a water pump 3, an ejector 4, a connecting pipe 5, and an ozone generator 6 to form an ozone dosing device. This allows for easy installation at any location within the wastewater treatment pond, improving the efficiency of the ozone dosing device in wastewater treatment. It also enhances the ease of assembly and disassembly of the ozone dosing device. By providing a rotating adjustment ring 16 on the surface of the floating platform 1, along with a linkage rod 17 rotatably connected to the floating platform 1, the spray angle of the ejector 4 can be quickly adjusted to meet different usage needs, improving the versatility of the ozone dosing device.
