Description

Technical Field

[0001] This utility model relates to the field of water treatment equipment technology, and in particular to an ozone disinfection device for direct drinking water storage tanks. Background Technology

[0002] Currently, most direct drinking water storage tank disinfection devices use ozone disinfection technology. Ozone is generated by external equipment and then transported to the water tank through pipelines to mix the gas and liquid, thereby eliminating microorganisms such as E. coli. The aeration tank inside the water tank is used to increase the gas-liquid contact area. Currently, common installation methods for aeration tanks require opening holes in the tank body or welding brackets, which can damage the structural integrity of the water tank. Another method involves suspending the tank inside with steel wire ropes, but in practice, due to the lack of stable support and restraint, some shaking can occur, making it easy for leaks to occur at the hose joints where hose clamps are used. Utility Model Content

[0003] The purpose of this invention is to address the shortcomings of existing technologies, such as the need to damage the water tank structure during installation or the tendency to shake and leak, and to propose an ozone disinfection device for direct drinking water storage tanks.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: The ozone disinfection device for direct drinking water storage tank includes a water tank and a support frame fixedly installed inside it, and also includes: An ozone generator is installed outside the water tank; An aeration tank is vertically suspended inside the water tank and located below the water surface, with a semi-circular plate fixedly installed on its outer wall; The mounting bracket includes a vertical U-shaped frame, a connecting shaft, and a semi-circular frame. The vertical U-shaped frame is laterally inserted into the vertical frame of the support. The two ends of the connecting shaft are respectively fixedly connected to the vertical U-shaped frame and the semi-circular frame. The side wall of the semi-circular frame is provided with a semi-circular groove that engages with the semi-circular plate. The ozone generator is connected to the aeration tank, and the ozone gas forms microbubbles through the microporous aeration disc at the bottom of the aeration tank, thereby achieving gas-liquid mixing and disinfection.

[0005] In one possible design, the mounting bracket further includes a transverse U-shaped plate, a connecting bracket, and a semi-circular shaft. The transverse U-shaped plate is laterally inserted into the transverse frame of the bracket, and the two ends of the connecting bracket are respectively fixedly connected to the transverse U-shaped plate and the semi-circular shaft. The outer wall of the connecting shaft has a notch, the semi-circular shaft is fitted into the notch, and the outer walls of the connecting shaft and the semi-circular shaft share the same set of threads. The outer walls of the connecting shaft and the semi-circular shaft are threaded with threaded sleeves.

[0006] In one possible design, the outer wall of the aeration tank is fixedly provided with a strip, and the outer wall of the semi-circular shaft is provided with a groove that cooperates with the strip to prevent the aeration tank from rotating.

[0007] In one possible design, the ozone generator is connected to the aeration tank via a single flexible hose.

[0008] In one possible design, the two ends of the hose are fixed to the ozone generator and the aeration tank respectively by hose clamps.

[0009] In one possible design, the semi-circular plate has a T-shaped cross-section, and the semi-circular groove is a matching T-shaped groove.

[0010] In this application, during actual use, the horizontal U-shaped plate is hung on the horizontal frame of the bracket from the side, and then the vertical U-shaped frame is attached to the adjacent vertical frame from the side, so that the semi-circular shaft is located inside the notch. Then, the threaded cylinder can be rotated so that the threaded cylinder moves and fits onto the outer wall of the semi-circular shaft to connect it. Then, the aeration tank is attached to the inner wall of the semi-arc frame, and then the attached semi-arc frame is rotated so that the semi-arc plate rotates into the interior of the semi-arc groove for connection. The insert will also rotate synchronously. When the insert rotates into the interior of the groove, the threaded cylinder is rotated again so that the threaded cylinder fits onto the outer wall of the insert, thereby limiting its position and achieving overall fixation.

[0011] In this utility model, the ozone disinfection device for the direct drinking water storage tank, through a combined screw structure, can rotate the threaded cylinder to different positions, so as to fit and limit different components, thereby achieving overall fixation, ensuring convenient operation and stable installation. In this utility model, the ozone disinfection device for the direct drinking water storage tank has a detachable installation structure, which can achieve both stable installation to avoid shaking and disassembly for easy subsequent maintenance. In this invention, the aeration tank can be installed without drilling or welding, thus avoiding damage to the integrity of the internal structure of the water tank. At the same time, it is stable during use and will not shake, thereby avoiding the risk of leakage at the hose interface. Attached Figure Description
