The front upper part of the evaporation tank 4 is fixedly connected with a gas-liquid separator 3, and the gas-liquid separator 3 can separate the steam and the mother liquid. The lower parts of the multiple groups of heating tanks 2 are fixedly connected through pipelines. The multiple groups of heating tanks 2 can make the steam be used in stages, thereby improving the efficiency of steam use. The three groups of evaporation tanks 4 and heating tanks 2 can perform three-stage evaporation of the mother liquid. The front part of the front-end gas-liquid separator 3 is fixedly connected to the upper part of the condenser 1, and the gas-liquid separator 3 can discharge the steam into the interior of the condenser 1.

[0034] Reference Figure 2 , Figure 4 The lower end of the condenser 1 is fixedly connected to a circulation pipe 5, which allows the coolant to circulate so that the steam can be cooled into condensed water. The upper part of the circulation pipe 5 is fixedly connected to a liquid outlet 6, and the lower part of the circulation pipe 5 is fixedly connected to a liquid inlet 7. The liquid inlet 7 at the lower end allows the coolant to flow in, and the liquid outlet 6 at the upper end allows the coolant to flow out, so that the coolant can circulate and achieve a better cooling effect, and can be recycled. The inside of the circulation pipe 5 is slidably connected to a scraper frame 13, which is composed of circular rings at the upper and lower ends and trapezoidal rods at the side ends. Impurities inside the circulation pipe 5 can be scraped off so that they can flow out with the water flow, so that the interior does not need to be disassembled for cleaning, reducing the possibility of blockage.

[0035] Reference Figure 4-Figure 6The upper part of the scraper frame 13 is fixedly connected with a supporting groove 14, which keeps the circulation pipe 5 closed and can drive the internal scraper frame 13 to rotate. The upper part of the supporting groove 14 is slidably connected to the upper end of the circulation pipe 5, and the circulation pipe 5 limits the supporting groove 14 to only rotate. The side end of the supporting groove 14 is slidably connected to the inside of the T-block 15, and the T-block 15 is limited by the supporting groove 14 to only slide vertically within a fixed distance, so that the sliding ring 11 will not fall off, and the upper part of the T-block 15 is fixedly connected with a sliding ring 11, and the rotation of the sliding ring 11 can drive the T-block 15 to rotate, so that the support groove 14 can rotate accordingly, and the outer part of the sliding ring 11 is slidably connected to the inner part of the upper end of the circulation pipe 5, and the side end of the sliding ring 11 is fixedly connected with a card block 10. The card block 10 is limited by the upper end of the circulation pipe 5 and will not rotate, so that the sliding ring 11 can remain fixed and will not rotate by itself, and the lower end of the card block 10 is externally slidably connected to the top of the circulation pipe 5, and the middle external sliding connection of the condenser pipe 1 is provided with a cleaning component.

[0036] Reference Figure 1-Figure 3 The cleaning component includes a sliding groove 9, which is a circular tube with circular holes at the upper and lower parts of the side ends. The outer part of the sliding groove 9 is slidably connected to the middle outer part of the condenser 1. The upward sliding can make the lower end of the sliding groove 9 closed and the detergent can be added through the circular hole at the upper end, so that the detergent can enter the interior of the circulation pipe 5 through the circular hole at the lower end for cleaning with the flow of water. The upper and lower parts of the sliding groove 9 are fixedly connected with a block 8, and the block 8 makes the sliding groove 9 only slide vertically within a fixed distance and will not slide out of the middle inner part of the condenser 1. The side of the block 8 is in contact with the middle outer part of the condenser 1, and the lower part of the upper end block 8 is fixedly connected with a magnet 12. The adsorption of the magnet 12 can make the upper end block 8 contact with the middle outer part of the condenser 1, so that the sliding groove 9 remains fixed and does not slide, so that the upper end of the sliding groove 9 is kept closed, and the lower part of the magnet 12 is in contact with the middle upper part of the condenser 1.

[0037] Working principle: The potassium permanganate electrolytic mother liquor can enter the interior of the whole device through the rear heating tank 2, and enter the interior of the evaporation tank 4 for evaporation after being heated by steam. The heating tank 2 allows it to circulate and heat and flow, and can be discharged into the interior of the heating tank 2 of the next level. After the evaporation treatment of the three groups of heating tanks 2 and evaporation tanks 4, the raw materials are discharged, and the gas-liquid separator 3 discharges the steam into the interior of the condenser 1. At this time, the liquid inlet 6 discharges the coolant into the interior of the circulation tube 5 and discharges it through the liquid outlet 7, so that the coolant can circulate and flow to cool the steam to make it condensed water. When cleaning is needed, the sliding ring 11 can be slid up, and the sliding ring 11 drives the block 10 to slide out of the upper end of the circulation tube 5. At this time, the T-block 15 slides up with the sliding ring 11 until the T-block 15 slides up. The lower part of the block 15 is limited by the support groove 14, and then the sliding ring 11 is rotated, the sliding ring 11 drives the T-block 15 to rotate, and the T-block 15 drives the support groove 14 to rotate. The support groove 14 can drive the scraper frame 13 to rotate to scrape the impurities on the inner wall of the circulation pipe 5 and flow out with the water flow, and then slide down so that the sliding ring 11 drives the T-block 15 and the block 10 to slide down until the block 10 slides to the side end and contacts the upper part of the circulation pipe 5, and can slide up so that the sliding groove 9 slides up until the upper part of the lower block 8 contacts the upper part of the circulation pipe 5. At this time, the lower circular hole of the sliding groove 9 is closed, and the detergent is poured into the interior of the sliding groove 9 through the upper circular hole, and then slides down until the upper end block 8 and the lower part of the magnet 12 contact the upper part of the circulation pipe 5. At this time, the detergent dissolves in the water flow for cleaning.
