Description

Technical Field

[0001] The utility model relates to the technical field of water body maintenance and disinfection, in particular to an anti-backflow component for an ozone generator. Background Technique

[0002] An ozone generator is a device used to produce ozone. Ozone is easy to decompose and cannot be stored, so it needs to be produced and used on-site. Therefore, ozone generators are required in all scenarios where ozone is needed. Ozone generators are widely used in the fields of tap water, sewage, industrial oxidation, and space sterilization. Ozone is a globally recognized spectral high-efficiency germicidal disinfectant, which uses air or oxygen as raw materials and generates ozone by high-frequency high-voltage discharge. Ozone has an active chemical property and is a strong oxidant. It can quickly kill bacteria in the air at a certain concentration, leaving no toxic residues and not forming secondary pollution.

[0003] In the technical field of artificial breeding of the Yangtze finless porpoise, a mature breeding and cultivation system has been constructed. The breeding and cultivation process has relatively high requirements for water quality. The ozone generator is one of the important devices used to disinfect the water body during the breeding and cultivation process. The ozone generator generates ozone by means of high-voltage discharge. However, in actual applications, the disadvantage of this device is that in the event of a sudden water cut or power outage, the water flow will directly flow into the quartz glass tube used for high-voltage discharge along with the ejector, resulting in the explosion of the quartz glass tube and directly damaging the core components of the ozone generator. Therefore, there is room for improvement. Content of the Utility Model

[0004] The utility model aims to solve the technical problem in the prior art that water flows back into the quartz glass tube and damages the ozone generator in the event of an accidental power outage, and provides an anti-backflow component for an ozone generator.

[0005] To solve the above technical problems, the technical solution provided by the utility model is: an anti-backflow component for an ozone generator, including a control box and an ozone generator; an air inlet pipe is connected to the upper end of the ozone generator;

[0006] A water cooling control component is arranged between the control box and the ozone generator. The water cooling control component includes an installation plate arranged in the control box, a cooling box arranged on the installation plate, a water tank arranged on the cooling box, a first water distribution pipe connected to the water tank, and the first water distribution pipe is coiled in a serpentine shape in the cooling box; a second water distribution pipe is connected to the first water distribution pipe near the upper end; valves are arranged on both the first water distribution pipe and the second water distribution pipe, and the second water distribution pipe and the lower end of the first water distribution pipe are connected to an outlet pipe through a three-way pipe fitting, and the outlet pipe extends out of the control box and is communicated with the ozone generator; a temperature sensor is arranged in the ozone generator;

[0007] One side of the ozone generator is provided with an anti-backflow structure, which includes a water storage cylinder. The upper end of the water storage cylinder is provided with a water inlet pipe; the lower end of the ozone generator is provided with an ozone output pipe, and the other end of the ozone output pipe extends into the water storage cylinder. The upper end of the water storage cylinder is connected with a second ozone output pipe; one side of the water storage cylinder is connected with a Z-shaped overflow pipe.

[0008] Preferably, an installation bottom plate is provided below the control box and the ozone generator, and cushion feet are provided at both ends below the installation bottom plate.

[0009] Preferably, the intake pipe is connected to an external gas source.

[0010] Preferably, a support frame is provided on one side of the ozone generator, and a through hole capable of accommodating the ozone output pipe is provided on the support frame.

[0011] Preferably, the lower end of the overflow pipe is at one-third of the height of the water storage cylinder, and the upper end of the overflow pipe is at two-thirds of the height of the water storage cylinder.

[0012] The advantages of the present utility model compared with the prior art are as follows: The water level in the water storage cylinder is controlled by the overflow pipe, so that the water level in the water storage cylinder has an upper limit and cannot flow back into the ozone generator through the ozone output pipe. Therefore, in the case of water cut-off and power failure, the water body will not flow back through the port of the ejector and damage the ozone generator;

[0013] In addition, when cooling the ozone generator by water cooling, the water cooling amplitude can be adjusted according to its actual temperature, which is more practical. Brief Description of the Drawings

Detailed Description of the Embodiment

[0018] The following further describes the present utility model in detail with reference to the drawings.

[0019] Embodiment 1, combined with the attached Figure 1, An ozone generator anti-backflow component, including a control box 1 and an ozone generator 2; there is an installation base plate 3 under the control box 1 and the ozone generator 2, making the overall integrity high and not scattered. There are feet at both ends under the installation base plate 3 to avoid the bottom plate directly contacting the ground, preventing water and dirt. The upper end of the ozone generator 2 is connected with an air inlet pipe 4, and the air inlet pipe 4 is connected to an external air source and leads into the ozone generator 2.

[0020] Combined with the attached Figure 1 、 2 , There is a water-cooling control component between the control box 1 and the ozone generator 2. The water-cooling control component includes an installation plate in the control box 1, and a cooling box 5 is arranged on the installation plate. There is a water tank 6 on the cooling box 5. The water tank 6 is connected with a first water distribution pipe 7, and the first water distribution pipe 7 is coiled in a serpentine shape in the cooling box 5; a second water distribution pipe 8 is connected near the upper end of the first water distribution pipe 7; valves are arranged on both the first water distribution pipe 7 and the second water distribution pipe 8. The second water distribution pipe 8 and the lower end of the first water distribution pipe 7 are connected with a water outlet pipe 9 through a tee pipe fitting. The water outlet pipe 9 extends out of the control box 1 and is communicated with the ozone generator 2; a temperature sensor is arranged in the ozone generator 2; According to the temperature displayed by the temperature controller, select to open the first water distribution pipe 7 or the second water distribution pipe 8. Since the lengths of the first water distribution pipe 7 and the second water distribution pipe 8 in the cooling box 5 are different, their cooling amplitudes are also different, so the cooling degree of the ozone generator 2 is also different, and it can be selected automatically.

[0021] Combined with the attached Figure 1 、 3 , There is an anti-backflow structure on one side of the ozone generator 2. The anti-backflow structure includes a water storage cylinder 10, and an inlet pipe 11 is arranged at the upper end of the water storage cylinder 10; an ozone output pipe 12 is arranged at the lower end of the ozone generator 2, and the other end of the ozone output pipe 12 extends into the water storage cylinder 10. There is a support frame on one side of the ozone generator 2, and a through hole capable of accommodating the ozone output pipe 12 is arranged on the support frame to make the ozone output pipe 12 more stable and not easy to shake when the air flow is output; an ozone output pipe two 13 is connected to the upper end of the water storage cylinder 10; a Z-shaped overflow pipe 14 is connected to one side of the water storage cylinder 10. The lower end of the overflow pipe 14 is at one-third of the height of the water storage cylinder 10, and the upper end of the overflow pipe 14 is at two-thirds of the height of the water storage cylinder 10. Thus, when the liquid level in the water storage cylinder 10 exceeds one-third, water starts to enter the overflow pipe 14. When the liquid level in the water storage cylinder 10 exceeds two-thirds, the overflow pipe 14 discharges water outward, so that the water volume in the water storage cylinder 10 will not exceed the horizontal plane where the upper end of the overflow pipe 14 is located, and thus will not flow back into the ozone generator 2.

[0022] Working principle of the utility model: The air inlet pipe 4 is connected to an external air source and introduced into the ozone generator 2. After ozone is prepared, it is transmitted to the water storage cylinder 10 through the ozone output pipe 12 and directly output through the ozone output pipe two 13 at the upper end for gas-liquid mixing with the water body. If there is an accidental water cut or power cut, the water in the water body will flow back through the externally connected jet port and will first flow into the water storage cylinder 10. If the water level rises too high and exceeds the horizontal line at the upper end of the overflow pipe 14, it will flow out directly through the overflow pipe 14, thus ensuring that the water level in the water storage cylinder 10 is lower than the upper limit and will not flow into the ozone generator 2.

[0023] The above describes the present utility model and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present utility model, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative efforts without departing from the creative purpose of the present utility model, they shall fall within the protection scope of the present utility model.
