Its core function is to convert the water in the wastewater into steam through heating and evaporation, and then condense and recover it.
[0003] Patent application publication number CN218709338U discloses a wastewater evaporator. It includes a preheating chamber, a heat exchanger, and a wastewater evaporator body. The heat exchanger and the wastewater evaporator body are located on the left and right sides of the preheating chamber, respectively, and are connected by a pipe. A conveying pipe connected to the bottom of the preheating chamber is fixedly connected to its interior. When using this patent, the wastewater enters the wastewater evaporator for evaporation after its temperature rises. However, when using the aforementioned prior art to treat high-salt organic wastewater, the high-salt wastewater easily precipitates inorganic salt crystals during heating, which adhere to the surface of the heating pipe to form a hard scale layer, resulting in a sharp decrease in heat transfer efficiency and requiring frequent cleaning.
[0004] In view of the existing patents, there is a need to provide a self-scaling descaling device for high-salt organic wastewater evaporators. Utility Model Content
[0005] In order to overcome the shortcomings of the existing patents used to treat high-salt organic wastewater, which are prone to precipitating inorganic salt crystals during the heating process and adhering to the surface of the heating tube to form a hard scale layer, resulting in a sharp drop in heat transfer efficiency and requiring frequent cleaning, this utility model provides a self-descaling device for descaling high-salt organic wastewater evaporators.
[0006] To address the aforementioned problems, this utility model adopts the following technical solution: a descaling device for a high-salt organic wastewater evaporator, comprising a mounting plate, a boiling chamber, a heater, a condenser, a compressor, and an air cooler. The boiling chamber is mounted on the mounting plate, the heater is mounted inside the boiling chamber, the condenser is mounted inside the boiling chamber, the compressor is mounted on the mounting plate, and an air cooler is installed on the boiling chamber. The device also includes an electric cylinder, a push rod, a mounting frame, a scraper, and a descaling brush. The electric cylinder is mounted on the boiling chamber, a push rod is mounted on the telescopic rod of the electric cylinder, and the mounting frame is fixedly connected to the push rod. Four descaling brushes are rotatably mounted on the mounting frame, and a scraper is fixedly connected to the mounting frame, with the scraper contacting the inner wall of the boiling chamber.
[0007] In one embodiment, the device further includes a connecting plate, an impact rod, an elastic element, and a vibrating plate. The heater is provided with four vibrating plates, and four connecting plates are fixedly connected to the mounting bracket. An impact rod is slidably provided on the connecting plate, and an elastic element is sleeved on the impact rod. The two ends of the elastic element are respectively connected to the impact rod and the connecting plate.
[0008] In one embodiment, a heat-insulating ring is also included, which is fitted over the boiling chamber.
[0009] In one embodiment, the mounting plate is provided with anti-slip grooves.
[0010] In one embodiment, the vibrating plate is provided with a plurality of elliptical blocks.
[0011] In one embodiment, the surface of the impact rod that contacts the vibrating plate is arc-shaped.
[0012] Compared with the prior art, the present invention has the following technical effects: 1. The extension rod of the electric cylinder drives the push rod to move the mounting bracket up and down, the descaling brush moves accordingly and scrapes off the scale layer on the surface of the heater, and the scraper cleans the adhering material on the inner wall of the boiling chamber at the same time, so as to achieve comprehensive descaling, continuously keep the heating surface clean, maintain a high heat transfer coefficient, and save energy and reduce consumption.
[0013] 2. The impact rod is squeezed by the elliptical block of the vibrating plate. Under the action of the elastic element, the impact rod moves inward and outward to impact the vibrating plate on the heater, generating high-frequency vibration, which causes the hard scale layer on the surface of the heater to break and loosen, thus enhancing the descaling effect.

Detailed Implementation
[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0020] Example 1: A descaling device for a high-salt organic wastewater evaporator, see reference. Figures 1-3 As shown, the system includes a mounting plate 1, a boiling chamber 2, a heater 3, a condenser 4, a compressor 5, and an air cooler 6. The boiling chamber 2 is mounted on the mounting plate 1. The heater 3 is bolted to the lower part of the boiling chamber 2, and the condenser 4 is bolted to the upper part of the boiling chamber 2. The compressor 5 is mounted on the right side of the mounting plate 1, and the compressor 5 is connected to the upper and lower parts of the boiling chamber 2. The upper and lower parts of the boiling chamber 2 are also self-connected. The lower part of the boiling chamber 2 also has a raw material inlet and outlet. The air cooler 6 is located on the left side of the boiling chamber 2, and the air cooler 6 is connected to the upper and lower parts of the boiling chamber 2. It also includes an electric cylinder 7, a push rod 8, a mounting bracket 9, a scraper 10, and a cleaning brush 11. The electric cylinder 7 is bolted to the top of the boiling chamber 2. The push rod 8 is mounted on the telescopic rod of the electric cylinder 7. The push rod 8 is located inside the boiling chamber 2. The mounting bracket 9 is welded to the bottom of the push rod 8. The cleaning brush 11 is symmetrically rotated on both sides of the mounting bracket 9. The cleaning brush 11 can contact the heater 3 when it moves. The scraper 10 is welded to the upper part of the mounting bracket 9. The scraper 10 contacts the inner wall of the boiling chamber 2.
[0021] See Figure 1 As shown, it also includes a heat insulation ring 16, and the lower part of the boiling chamber 2 is fitted with a heat insulation ring 16.
[0022] See Figure 1 As shown, the bottom of the mounting plate 1 is provided with anti-slip grooves.
[0023] When this device is needed, high-salt organic wastewater is injected into boiling chamber 2 through the raw liquid inlet. Heater 3 heats and evaporates the high-salt organic wastewater in the lower part of boiling chamber 2. The generated steam rises to condenser 4 for condensation. Compressor 5 is connected to the upper and lower parts of boiling chamber 2 to form a forced circulation to enhance evaporation efficiency. Air cooler 6 assists in cooling. The condensate is finally discharged from the outlet. The insulation ring 16 fitted at the lower part of boiling chamber 2 is made of heat insulation material to reduce heat loss and maintain a stable internal temperature of boiling chamber 2. After recycling, wait for the boiling chamber 2 to cool down before starting electric cylinder 7. The telescopic rod of electric cylinder 7 drives push rod 8 to move mounting frame 9 up and down. Descaling brush 11 moves accordingly and scrapes off the scale layer on the surface of heater 3. Scraper 10 cleans the deposits on the inner wall of boiling chamber 2 at the same time to achieve comprehensive descaling, continuously keep the heating surface clean, maintain a high heat transfer coefficient, and save energy and reduce consumption.
[0024] Example 2: Based on Example 1, refer to Figure 2 and Figure 4As shown, it also includes a connecting plate 12, an impact rod 13, an elastic element 14, and a vibrating plate 15. Four vibrating plates 15 are provided on the heater 3, and four connecting plates 12 are fixedly connected to the mounting bracket 9. An impact rod 13 is slidably provided on the connecting plate 12, and an elastic element 14 is sleeved on the impact rod 13. The two ends of the elastic element 14 are respectively connected to the impact rod 13 and the connecting plate 12.
[0025] See Figure 2 As shown, multiple elliptical blocks are provided on the vibrating plate 15 to compress and move the impact rod 13.
[0026] See Figure 4 As shown, the contact surface between the impact rod 13 and the vibrating plate 15 is arc-shaped.
[0027] When the mounting frame 9 moves, the mounting frame 9 drives the connecting plate 12 and the impact rod 13 to move. The impact rod 13 is squeezed outward by the elliptical block of the vibrating plate 15. At the same time, the impact rod 13 squeezes the elastic element 14, and the elastic element 14 is compressed accordingly. Under the action of the elastic element 14, the impact rod 13 moves inward and outward to impact the vibrating plate 15 on the heater 3, generating high-frequency vibration, which causes the hard scale layer on the surface of the heater 3 to break and loosen, thereby enhancing the descaling effect.
