A scraper rod 5 is fixedly installed on the lower end of the output shaft of the machine 4, and a bracket 6 is fixedly installed on the inner wall of the upper end of the evaporation barrel 1 on the side of the scraper rod 5, and a blower mechanism 8 is provided on the inner wall of the bracket 6. An air duct 7 is installed on the side of the upper end of the evaporation barrel 1 away from the feed pipe 2, and a bend pipe 10 is fixedly penetrated at the lower end of the end of the air duct 7, and a water tank 11 is fixedly connected to the outer wall of the bend pipe 10, and a water inlet 12 and a water outlet 13 are respectively installed at the upper and lower ends of the water tank 11, and feet 14 are respectively fixed to the lower end outer walls of the water tank 11 and the side of the evaporation barrel 1.

[0022] The scraper rod 5 and the bracket 6 form a rotating structure, and the scraper rod 5 and the evaporation barrel 1 are in close contact, so that the motor 4 drives the scraper rod 5 to rotate stably relative to the bracket 6, so that the scraper rod 5 continuously cleans the inner wall of the evaporation barrel 1, thereby avoiding scaling of the inner wall of the evaporation barrel 1.

[0023] The air blowing mechanism 8 includes a transmission rod 801, a secondary bevel gear 802 and a fan blade 803, and the transmission rod 801 is movably mounted on the inner wall of the bracket 6, and the secondary bevel gear 802 and the fan blade 803 are respectively fixed to the outer walls at both ends of the transmission rod 801, so that the air blowing mechanism 8 can be driven when the scraper rod 5 rotates, so that the air blowing mechanism 8 blows the steam, thereby ensuring the evaporation efficiency of the device.

[0024] The transmission rod 801 and the bracket 6 are rotatably arranged, and the cross-section of the bracket 6 is arranged in an "E" shape, so as to improve the stability of the transmission rod 801 when rotating relative to the bracket 6.

[0025] The outer wall of the scraper rod 5 on the side of the secondary bevel gear 802 is fixedly connected to the main bevel gear 9, and the main bevel gear 9 and the secondary bevel gear 802 are meshed. The fan blades 803 are located inside the air duct 7, so that when the scraper rod 5 rotates, the main bevel gear 9 drives the secondary bevel gear 802, so that the transmission rod 801 drives the fan blades 803 to rotate, blowing the steam to flow rapidly in the air duct 7.

[0026] The cross-sectional shape of the curved pipe 10 is set to a spiral shape, and the water tank 11 and the evaporation barrel 1 are fixedly connected, which is convenient for increasing the contact area between the curved pipe 10 and the water in the water tank 11, so that the water in the water tank 11 can fully absorb the heat of steam, avoid wasting thermal resources, and at the same time facilitate improving the overall stability of the device.

[0027] Working principle: When using the anti-scaling evaporator, first Figure 1-4 As shown, the user injects wastewater into the evaporation barrel 1 through the feed pipe 2, and then the user injects cold water into the water tank 11 through the water inlet 12. Next, the user starts the heating mechanism and the motor 4 arranged on the lower surface of the evaporation barrel 1. At this time, the heating mechanism below the evaporation barrel 1 heats the wastewater in the evaporation barrel 1 to evaporate the wastewater. At the same time, the motor 4 drives the scraper rod 5 to rotate stably relative to the bracket 6. Then, the scraper rod 5 stirs the wastewater while continuously cleaning the inner wall of the evaporation barrel 1, thereby preventing the inner wall of the evaporation barrel 1 from scaling. Then, as the scraper rod 5 rotates, the scraper rod 5 drives the main bevel gear 9 to rotate, and then the main bevel gear 9 drives the secondary bevel gear 802 to rotate, and then the secondary bevel gear 802 drives the transmission rod 801 to rotate relative to the bracket 6. , and then the transmission rod 801 drives the fan blade 803 to rotate. At this time, the steam is discharged from the device through the air duct 7 and the curved pipe 10. As the fan blade 803 rotates, the flow rate of the gas in the air duct 7 is increased, so that the steam is quickly discharged from the device, thereby ensuring the evaporation rate of the device, and as the steam flows in the curved pipe 10, the steam heats the curved pipe 10. At this time, the cold water in the water tank 11 absorbs the heat emitted by the curved pipe 10, thereby avoiding the waste of thermal resources. Therefore, the device is convenient for driving the scraper to rotate stably while increasing the steam flow rate. Then, when the waste water is evaporated, the user opens the discharge pipe 3 to discharge the concentrated waste water from the device, and then the user opens the water outlet 13 to discharge the hot water from the device.
