[0042] The working principle of the utility model is as follows:

[0043] The waste water after filtration treatment enters the evaporation device 3 from the waste water inlet pipeline 1, the heating base 5 continuously heats, the waste water at the bottom is firstly heated and then flows upward through the side exchange pipe 10 due to the density effect, so that an automatic circulating power is generated in the evaporation cylinder 6, heated water is continuously exchanged to the upper side, and the heating efficiency of the device is improved.

[0044] During the heating process, the foam generated by the boiling of wastewater accumulates on the upper layer. After the boiling water passes through the holes of the flow stabilizer plate 7, a stable liquid surface is formed on the upper layer. The foam is pushed outward into the steam pipe 2 by the blades 13 of the stirring rod 12 driven by the drive motor a11, thereby removing the foam generated by the boiling of wastewater in time and preventing the foam from covering and reducing the evaporation efficiency of the device.

[0045] The foam generated in the evaporator 3 is pushed to the right by the scraper mechanism a into the steam pipe 2. Because the steam pipe 2 is inclined towards the airflow direction, the foam and some steam enter the tank 14 from the foam pipe 16. After the evaporator 3 has been running for a period of time, the brine pipe 15 automatically opens, discharging the concentrated brine from the lower layer into the tank 14. The level gauge 8 controls the wastewater inlet pipe 1 to add water to the evaporator 3 to maintain the liquid level based on the level signal. The high-temperature concentrated brine and foam evaporate in the tank 14 according to their own temperature and the temperature brought by the steam in the foam pipe 16. The evaporated water vapor flows into the steam pipe 2 through the bypass steam pipe 18. The check valve group 26 prevents the steam in the steam pipe 2 from flowing back into the tank 14. After prolonged use, calcium deposits will form at the bottom of the tank 14. During crystallization and precipitation, the controller controls the extension of the telescopic electric cylinder 21, which drives the sediment scraper 25 at the bottom of the small sleeve 20 to the bottom of the tank 14. The drive motor b24 drives the gear 23 to rotate, which causes the rack 22 to drive the large sleeve 19 to rotate on the tank 14. This causes the sediment scraper 25 at the bottom of the small sleeve 20 to rotate, scraping off the sediment at the bottom and sides of the tank 14. Finally, clean water is introduced from the wastewater inlet pipe 1 and enters the tank 14 through the brine pipe 15. The clean water and the scraped sediment are discharged from the sewage pipe 17. In this way, the high-concentration brine in the evaporation device 3 is separated and evaporated in time. While ensuring that the crystallization and precipitation phenomenon inside the evaporation device 3 is reduced, the heating efficiency of the device is guaranteed. The retractable scraper mechanism b can also prevent the scraper from crystallizing and reduce the workload of device maintenance.

[0046] This concludes the description of the working principle of the device.
