[0029] Specifically, after the motor 4 is turned on, the rotating shaft 5 will drive the scraper 6 to scrub the inside of the evaporator 2, which helps to remove sediment and dirt, keep the equipment clean, and prevent dirt from affecting the evaporation efficiency. At the same time, the water in the evaporator 2 can be stirred during the rotation of the scraper 6, so as to ensure that the water temperature in the evaporator 2 can continue to evaporate, so that the heat can be evenly distributed, improve the evaporation rate of water, and ensure the uniformity of the evaporation process. The evaporated water vapor will be absorbed into the collection box 10, while the material precipitated from the sewage will enter the box at the side of the evaporator 2 through the fixed pipe 13.

[0030] Reference Figure 6 The water inlet mechanism 7 includes a water inlet pipe 701 and a filter plate 707. A fixed box 702 is fixedly installed at the front end of the water inlet pipe 701. A horizontal plate 703 is fixedly installed at the upper and lower ends of the outer side of the fixed box 702. A spring 706 is installed at one end of the two horizontal plates 703 facing each other. A fixed block 705 is fixedly installed at one end of the two springs 706 facing each other.

[0031] The water inlet pipe 701 is fixedly installed on the upper part of the outer side of the evaporator 2, and the filter plate 707 is movably installed between the two filter plates 707.

[0032] The filter plate 707 is movably mounted inside the fixed box 702.

[0033] Specifically, when the sewage enters the fixed box 702, it can be filtered by the filter plate 707. When the filter plate 707 needs to be replaced, pull the movable column 704 upwards, then take out the filter plate 707 outward, release the movable column 704 after putting the new filter plate 707 into the groove on the side of the fixed box 702, and the fixed block 705 will be restored to the original position by the spring 706, thereby clamping the filter plate 707. Through the use of the filter plate 707, suspended solids, impurities and particles in the sewage can be effectively removed, ensuring the cleanliness and qualification of the water quality. The process of quickly replacing the filter plate 707 simplifies the maintenance procedure, enabling the operator to complete the maintenance faster, improving the overall work efficiency and reducing downtime.

[0038] Working principle: after the motor 4 is turned on, the rotating shaft 5 drives the scraper 6 to brush the inside of the evaporation tank 2, and in the process of rotating the scraper 6, the water in the evaporation tank 2 can be stirred. After the spiral heating pipe 15 is opened, hot air will pass through the air inlets 1201 and be discharged into the inner end of the evaporation tank 2 from the air inlets 1202, and after the scraper 6 rotates, it can ensure that the water in the evaporation tank 2 can continuously evaporate water. The evaporated water vapor will be absorbed into the collection box 10, and the material separated from the sewage will enter the box at the side end of the evaporation tank 2 from the fixed pipe 13.

[0039] Secondly, when the sewage enters the fixed box 702, it can be filtered by the filter plate 707. When the filter plate 707 needs to be replaced, pull the movable column 704 upwards, then take out the filter plate 707 outward, release the movable column 704 after putting the new filter plate 707 into the groove on the side of the fixed box 702, and the fixed block 705 will be restored to the original position by the spring 706, thereby clamping the filter plate 707.
