[0002] Seawater desalination equipment refers to equipment specially used to desalinate seawater. There are two main methods for desalinating seawater, namely distillation and reverse osmosis. Whether it is seawater desalination or brackish water desalination, water pretreatment is the key to ensure the long-term stable operation of the reverse osmosis system. When formulating a seawater pretreatment plan, it should be fully considered that there are a large number of microorganisms, bacteria and algae in seawater. The reproduction of bacteria, algae and the growth of microorganisms in seawater will not only bring a lot of trouble to the water intake facilities, but also directly affect the normal operation of the seawater desalination equipment and process pipelines.

[0003] Ultrasonic desalination is a link in seawater treatment. However, scale will adhere to the inner wall of the device during the treatment. The long-term accumulation of scale will gradually reduce the treatment efficiency. Therefore, an anti-scaling device for ultrasonic desalination is proposed. Utility Model Content

[0013] 1. The anti-scaling device of the ultrasonic desalination device is provided with a scraper plate, a filter net and a cylinder shaft. The rotation of the cylinder shaft drives the scraper plate to rotate synchronously. The rotation of the scraper plate scrapes the inner wall of the treatment cylinder to prevent scale from adhering and accumulating on the inner wall of the treatment cylinder. The filter net blocks the scale under the scraping to prevent it from being discharged from the treatment cylinder synchronously with water.

The scale enters the lower end of the permeable cylinder shaft through the slot, and then the scale is transported upward during the rotation of the permeable spiral feeding plate. The generated scale can be continuously discharged to prevent a large amount of scale from clogging the upper surface of the filter bag net. BRIEF DESCRIPTION OF THE DRAWINGS
