Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, specifically relating to an evaporative wastewater treatment device. Background Technology

[0002] Wastewater evaporation treatment is a method that uses heat to evaporate water from wastewater, thereby concentrating and separating pollutants. Based on the principle of evaporation concentration and crystallization, this method is suitable for treating wastewater with high salinity and high concentration. By using multi-effect vacuum evaporation to concentrate and crystallize organic wastewater, salts in the concentrate can be separated and recovered through a salt collector. The condensate after evaporation is generally treated subsequently through biological processes to meet discharge standards. However, currently used wastewater evaporation treatment devices are prone to causing impurities in the wastewater to adhere to the walls of the evaporation chamber during the heating process. If not cleaned and treated promptly, long-term accumulation can create safety hazards for the evaporation device, potentially leading to explosions. To address the aforementioned issues, prior art disclosed in CN223163314U describes a wastewater evaporation treatment device. This prior art cleans the second treatment cylinder using a scraper. However, after prolonged use, this cleaning method causes wear and tear on the inner wall of the second treatment cylinder due to long-term friction, which in turn affects the heating effect on the water.

By driving the rotating shaft 13 to rotate, the rotation of the rotating shaft 13 can drive the stirring shafts 14 to stir the water in the heating inner tank 7, so that the water in the heating inner tank 7 is heated evenly, thereby accelerating the evaporation rate.

[0028] like Figure 1As shown, in a further preferred embodiment, the drive device includes a motor 15, the output shaft of which passes through the mounting bracket 1 and is rotatably connected. Specifically, the rotatable connection is achieved through a sealed bearing. The output shaft of the motor 15 is fixedly connected to the upper end of the rotating shaft 13.
