However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.
[0021] Example 1, as Figure 1-Figure 5 As shown, the utility model provides a novel high-salt wastewater evaporation device, including a preheating box 1, a feed port 2 is provided on the top of the preheating box 1, a power supply box 3 is fixedly connected to the bottom of the preheating box 1, the output end of the power supply box 3 passes through the bottom of the preheating box 1 and extends to the inside, the output end of the power supply box 3 is fixedly connected to a group of heating rods 4, a water inlet is provided on the outer surface of the preheating box 1, the outer surface of the water inlet is fixedly connected to a centrifugal pump 7, the output end of the centrifugal pump 7 passes through the insulation box 8 and the evaporation box 10 in sequence and extends to the inside of the evaporation box 10, a heating wire 9 is provided between the insulation box 8 and the evaporation box 10, a motor 11 is fixedly connected to the top of the evaporation box 10, the output end of the motor 11 passes through the top of the evaporation box 10 and extends to the inside, the output end of the motor 11 is fixedly connected to a rotating shaft 13, and the outer surface of the rotating shaft 13 is fixedly connected It is connected to a ratchet 12, a scraper 14 is fixedly connected to the bottom of the ratchet 12, a plurality of stirring blades 15 are fixedly connected to the outer surface of the bottom of the rotating shaft 13, a valve 16 is fixedly connected to the top of the evaporation box 10, a plurality of first support legs 5 are fixedly connected to the bottom of the preheating box 1, a plurality of second support legs 17 are fixedly connected to the bottom of the insulation box 8, one of the plurality of first support legs 5 and the second support legs 17 is fixedly connected to the bottom of the centrifugal pump 7 with a stabilizing plate 6, the heating wire 9 is distributed in a spiral shape, and the outer surface of the heating wire 9 fits the inner wall of the evaporation box 10, the inner wheel of the ratchet 12 is provided with a plurality of moving blocks, and a plurality of notches are opened inside the ratchet 12, and the notches are the same size as the moving blocks, the scraper 14 is designed to be inclined, and the outer surface of the scraper 14 fits the inner wall of the evaporation box 10, and the bottom of the scraper 14 does not fit the stirring blade 15.
[0022] The effect achieved by the entire embodiment 1 is that when the device is used, the preheating box 1 is stabilized by the first support leg 5, the insulation box 8 and the evaporation box 10 are stabilized by the second support leg 17, and the wastewater is connected to the wastewater pool through the feed port 2 on the top of the preheating box 1, and the wastewater is introduced into the preheating box 1. At this time, the heating rod 4 is energized by the power supply box 3, and the heating rod 4 heats the wastewater for pretreatment, so that the temperature difference of the wastewater rises and evaporates. When the temperature of the wastewater is completely raised, the centrifugal pump 7 is started to extract the wastewater in the preheating box 1 and the wastewater is pumped into the evaporation box 10. At this time, the heating wire 9 between the insulation box 8 and the evaporation box 10 is energized to heat and evaporate the evaporation box 10, and the electric power is started at the same time. The motor 11 drives the rotating shaft 13 to rotate clockwise, and the stirring blade 15 connected to the rotating shaft 13 rotates synchronously clockwise to stir the wastewater entering the evaporation box 10, so that the heating is more balanced. Evaporation and stirring are carried out synchronously, so that the evaporation efficiency is higher. When evaporation is completed, the rotation direction of the motor 11 is changed to make the rotating shaft 13 rotate counterclockwise. Under the action of the ratchet 12 rotating counterclockwise, the stirring blade 15 inside the ratchet 12 stops rotating, and the scraper 14 on the ratchet 12 rotates counterclockwise to perform a comprehensive descaling treatment on the inner wall of the evaporation box 10 to remove salt scale. After evaporation is completed, the valve 16 is opened to release the steam pressure inside the evaporation box 10, making it safer for the next evaporation, and completing the evaporation process.
[0023] Example 2, as Figures 1-4 As shown, it includes a preheating box 1, a feed port 2 is provided on the top of the preheating box 1, a power supply box 3 is fixedly connected to the bottom of the preheating box 1, the output end of the power supply box 3 passes through the bottom of the preheating box 1 and extends to the inside, the output end of the power supply box 3 is fixedly connected to a group of heating rods 4, a water inlet is provided on the outer surface of the preheating box 1, the outer surface of the water inlet is fixedly connected to the input end of a centrifugal pump 7, and the output end of the centrifugal pump 7 passes through the insulation box 8 and the evaporation box 10 and extends to the inside of the evaporation box 10.
[0024] The effect achieved by the entire embodiment 2 is that the wastewater is connected to the wastewater pool through the feed port 2 at the top of the preheating box 1, and the wastewater is introduced into the preheating box 1. At this time, the heating rod 4 is energized by the power supply box 3, and the heating rod 4 heats the wastewater for pretreatment, so that the temperature difference of the wastewater rises and evaporates, and the wastewater is preheated when the temperature of the wastewater is completely risen.
[0025] Working principle: When the device is in use, the preheating box 1 is stabilized by the first supporting leg 5, the heat preservation box 8 and the evaporation box 10 are stabilized by the second supporting leg 17, and the wastewater is connected to the wastewater pool through the feed port 2 on the top of the preheating box 1, and the wastewater is introduced into the preheating box 1. At this time, the heating rod 4 is energized through the power supply box 3, and the heating rod 4 pre-heats the wastewater to make the temperature of the wastewater rise and the temperature difference becomes smaller when evaporating. When the wastewater temperature rises, the centrifugal pump 7 is started to extract the wastewater in the preheating box 1 and the wastewater is pumped into the evaporation box 10. At this time, the heating wire 9 between the heat preservation box 8 and the evaporation box 10 is energized to heat and evaporate the evaporation box 10, and at the same time, the motor 11 is started to drive the rotating shaft 13, and the stirring connected to the rotating shaft 13 The blades 15 stir the wastewater entering the evaporation box 10. When evaporation is completed, the rotation direction of the motor 11 is changed to make the shaft 13 rotate counterclockwise. Under the action of the ratchet 12, the stirring blades 15 stop rotating, and the scraper 14 on the ratchet 12 performs a comprehensive descaling treatment on the inner wall of the evaporation box 10 to remove the salt scale. After evaporation is completed, the valve 16 is opened to release the steam pressure inside the evaporation box 10, thereby completing the evaporation process. The advantage of this device is that through the mutual cooperation of the motor 11, the shaft 13, the ratchet 12, and the scraper 14, when no stirring is performed, the scraper 14 scrapes off the salt scale covering the inner wall of the evaporation box 10 by changing the rotation direction, so that the evaporation process proceeds normally, thereby improving the evaporation efficiency of high-salt wastewater.

The model is selected according to the actual use, so the control method and wiring arrangement of the power supply box 3, the heating wire 9, and the motor 11 are no longer explained in detail.
