The evaporation treatment device for urban sewage treatment uses the movement function of the walking frame 1 to accurately move the evaporation component 6 and the stirring structure 5 to the sewage area. The stirring structure 5 is installed on the top of the evaporation component 6. During the evaporation process, impurities and pollutants in the sewage will gradually concentrate, eventually achieving the purpose of separating water and pollutants.

The sludge discharge component 8 can precisely control the amount and time of sludge discharge, making the entire sludge discharge process more stable and efficient. The drain component 9 can further drain the substances containing a small amount of water after evaporation, draining out as much residual water as possible, improving the treatment effect of sewage, and making the final substance have a lower water content, which is more convenient for subsequent solidification, landfill and other treatment operations. A filter structure 11 is installed on the other side of the upper surface of the walking frame 1. The filter structure 11 is connected to the evaporation component 6 through the steam discharge structure 10. The filter structure 11 is equipped with a filter screen, which can deeply filter the steam coming from the evaporation component 6 through the steam discharge structure 10, effectively intercepting tiny impurity particles and harmful substances carried in the steam, ensuring that the discharged steam is purer and reducing secondary pollution to the environment. The filter structure 11 is also equipped with an automatic cleaning device, which can clean the filter screen regularly to prevent the filter screen from clogging and ensure that the filtration effect is always stable. The sewage pump 2 is fixed on the upper surface of the walking frame 1. A water suction pipe 3 is installed on the input end of the sewage pump 2. The water suction pipe 3 is connected to the top of the evaporation component 6 through the water supply pipe 4. The sewage pump 2 can suck urban sewage into the evaporation component 6 through the water suction pipe 3 and the water supply pipe 4, providing a stable sewage supply for subsequent evaporation treatment.

An insulation layer is also provided between the outer evaporation tank 61 and the inner evaporation tank 62 to effectively reduce heat loss and improve energy utilization efficiency. The inner wall of the inner evaporation tank 62 is specially treated, with a smooth surface that is not easy to adhere to dirt, making it easy to clean and maintain.

[0023] The implementation principle of this application is as follows: When using this utility model, during testing, the water tank to be tested 23 is placed between the rear contour block 9 and the middle contour block 21. Then, the pressing mechanism drives the first sealing block 8 to move down through the connecting block 7, blocking the hole on one side of the water tank 23. During the pressing process, the first sealing block 8 can also press the side of the water tank 23 tightly against the surface of the sealing gasket 10 to maintain a seal. Then, the movable squeezing mechanism drives one end of the moving frame 17 until the second sealing block 18 covers the other side opening of the water tank 23. At the same time as the second sealing block 18 presses against one side of the water tank 23, the clamping mechanism also moves the water tank 23 downwards. The continuous contraction of the push rod 13, through the compression of the compression spring 16, can tightly press the sealing gasket 19 together with the water tank 23 to be tested. Then, the connecting pipe on one side of the main body 24 of the detector is connected to the air inlet 22 and the control cabinet 25 respectively for pressure testing. The test value is displayed on the display on one side of the main body 24 of the detector, and the pressure difference between the two is monitored in real time. If the test sample has a leak, its internal pressure will gradually decrease over time, while the pressure of the standard sample remains stable. The position of the intermediate contour block 21 on the mounting base 20 can be adjusted as needed, and the second sealing block 18 of different sizes can also be replaced to meet the usage effect.
