Technical Field

[0002] The discharge of industrial wastewater has caused serious environmental pollution. In order to protect the environment, it is necessary to strictly control the discharge of wastewater. All enterprises that produce industrial wastewater need to discharge the wastewater to a special sewage treatment plant for treatment before discharge. Heat pump technology is an efficient, environmentally friendly energy-saving technology that can be widely used in industrial production fields such as chemical industry, low-grade thermal energy utilization, seawater desalination, and sewage treatment. After heat pump evaporation and concentration, distilled water that meets the emission standards can be extracted from the sewage.

[0003] The currently published patent: CN214612004U discloses a low-temperature vacuum evaporator, which is provided with a motor. The motor can drive the stirring blade, the first scraper and the second scraper to rotate through the rotating rod, so that the rotating first scraper and the second scraper can be used to scrape off the impurities adhering to the inner wall of the liquid storage tank, thereby ensuring the normal use of the liquid storage tank.

However, the first scraper and the second scraper only scrape off the impurities adhered to the inner wall of the liquid storage tank, and do not discharge the impurities from the interior of the liquid storage tank.
