Description

Technical Field

[0001] This utility model relates to the field of sterilization device technology, specifically a circulating water ultraviolet sterilization device. Background Technology

[0002] The circulating water ultraviolet sterilization device is a sterilization device specifically designed for circulating water systems, such as industrial circulating cooling water, central air conditioning circulating water, swimming pool circulating water, and aquaculture circulating water. It uses ultraviolet light, especially short-wave ultraviolet light with a wavelength of 253.7nm (UVC), as its core medium. By irradiating microorganisms (bacteria, viruses, algae, protozoa, etc.) in the circulating water with specific wavelengths of ultraviolet light, it damages their DNA or RNA molecular structure, causing the microorganisms to lose their ability to grow and reproduce or even die directly. This achieves the elimination of harmful microorganisms in the circulating water, inhibits the growth of biological slime (bacteria and algae), and ensures the stable operation of the circulating water system.

[0003] Existing patent document CN217202159U discloses an ultraviolet sterilization device for recirculating aquaculture systems. The device consists of two parts: an outer and a inner one. The outer part includes a light-transmitting watertight protective cover, a cylindrical titanium alloy pressure-resistant watertight shell, a cable connector, and a base connector. The cylindrical titanium alloy pressure-resistant watertight shell and the light-transmitting watertight protective cover constitute the outer shell. The cable connector is installed at the bottom of the device, used for connecting an external power supply line and also connected to the base connector for controlling the timing circuit. The base connector connects to a control module. The control module regulates the external power supply and converts it into a constant current, which is then input to the ultraviolet light-emitting substrate. This device has a high degree of integration, a small overall size, and is easier to install compared to many existing devices.

[0004] Existing circulating water UV sterilization devices, while effectively sterilizing water during operation, suffer from the problem of scale gradually adhering to the inner wall and surface of the UV lamps after the water flows through the device. Due to structural limitations, it is difficult to effectively clean the accumulated scale on the UV lamps and inner walls. As operating time increases, the scale continues to accumulate, severely hindering the transmission of UV light and significantly reducing the sterilization effect. To address this issue, we propose a circulating water UV sterilization device. Utility Model Content

[0013] Preferably, both the outer cleaning ring and the inner cleaning ring are annular structures, and both are made of rubber material.

[0014] (III) Beneficial Effects

[0015] This invention provides a circulating water ultraviolet sterilization device, which has the following beneficial effects:

[0016] (1) This circulating water ultraviolet sterilization device, through the cleaning motor, cleaning screw and cleaning plate, when the circulating water ultraviolet sterilization device is used, water flows into the sterilization body through the water inlet pipe, and at the same time the sterilization lamp tube emits ultraviolet light to sterilize the water. Then the water is discharged through the water outlet pipe. When the dirt in the water adheres to the inside of the sterilization body, the cleaning motor can be started. At this time, the cleaning motor drives the cleaning screw to rotate, and the cleaning plate moves up and down due to the rotation direction of the cleaning screw. The cleaning outer ring on the outside of the cleaning screw can clean the dirt on the inner wall of the sterilization body, and the cleaning inner ring can clean the dirt on the outside of the sterilization lamp tube. This allows the sterilization device to effectively clean the dirt accumulated on the ultraviolet lamp and the inner wall, and avoid the continuous accumulation of dirt to hinder the transmission of ultraviolet light, thus improving the sterilization effect.
