A high-frequency vibrator is fixedly connected to one side of the outer wall of the support plate, and elastic plates are rotatably connected to both sides of the outer wall of the support plate.

[0014] An operation method of a high-salt wastewater evaporation and crystallization device, which uses the above-mentioned high-salt wastewater evaporation and crystallization device, and the method is as follows: S1: Pour the wastewater from the feed pipe into the evaporation chamber. Use the heating plate to evaporate the excess water in the wastewater and discharge it from the steam pipe. Then, send it into the treatment main body through the discharge pipe arranged at one end of the bottom of the evaporation chamber. Use the material distribution component to break up the high-salt crystals, cooperate with the heating component to pre-treat the high-salt crystals, and then use the circulation component to clean the high-salt crystals more meticulously. S2: The material distribution component sets several arc-shaped plates on the outer wall of the rotating shaft ring.

Then, it is discharged into the ventilation disc through the air guiding hose arranged at the output end of the centrifugal fan, and uses the ventilation pipe to reheat the inside of the guiding pipe again.

[0015] Due to the adoption of the above technical solution, the technical progress achieved by the present invention compared with the prior art is: 1. The present invention provides a high-salt wastewater evaporation and crystallization device and its operation method. By setting several feeding plates on the inner wall of the rotating shaft ring, the high-salt crystals on the surface of the sieve mesh are stirred. Since the bottom of the feeding plate presents an inverted right angle shape, when the feeding plate rotates, the high-salt crystals fall into the feeding bin in small batches and multiple times along the holes of the sieve mesh. And the temperature in the feeding bin is relatively high. Due to the relatively small volume of the high-salt crystal clusters, the highly viscous concentrated liquid attached to their surface quickly loses its viscosity under the heating of the feeding bin, thus avoiding the mutual adhesion between the high-salt crystal clusters, and further solving the problem that in the traditional high-salt wastewater evaporation and crystallization device during use, after the high-salt wastewater evaporates, the high-salt crystals are stacked on each other, resulting in the difficult effective peeling of the highly viscous concentrated liquid inside. 2. The present invention provides a high-salt wastewater evaporation crystallization device and its operation method. By arranging a plurality of air pipes at the bottom of the air ventilation plate, and the number of the air pipes corresponding to the number of the guiding pipes, and the air pipes being inside the guiding pipes and not connected to the guiding pipes, and by arranging exhaust ports at the bottom on one side of the outer wall of the air pipes, and the bottom of the inner cavity of the air pipes being conical, high-temperature hot air moves along the inner wall of the guiding pipe, cleaning part of the high-salt crystals attached to the inner wall of the guiding pipe, keeping the inner wall of the guiding pipe smooth, and avoiding the high-salt crystals from attaching to the inner wall of the guiding pipe and causing the guiding pipe to be blocked. Further, it solves the problem that in the process of using the traditional high-salt wastewater evaporation crystallization device, it is difficult to effectively and carefully batch-treat the high-salt crystals, resulting in residual high-viscosity concentrated liquid in the high-salt crystals, and thus when the high-salt crystals are discharged, it is easy to cause the pipeline to be blocked.

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0019] As Figures 1 to 10 shown, a high-salt wastewater evaporation crystallization device according to an embodiment of the present invention includes a processing main body, a material distribution component for discharging the pretreated salt crystals in batches; a heating component for heating the high-salt crystals in the pipeline; a flow splitting component for evaporating the highly viscous concentrated liquid in the salt crystals; a guiding component for preventing the high-salt crystals from sticking to the pipeline; a circulation component for recovering the air heated by the pipeline and reheating and reusing it; an evaporation component for evaporating most of the water in the wastewater; and a stirring component for stirring the heated wastewater. The evaporation component includes a discharge pipe 20 fixedly connected to the top of the processing main body 1, and one end of the discharge pipe 20 is fixedly connected to an evaporation chamber 21. A heating plate 22 is fixedly connected to the bottom of the inner wall of the evaporation chamber 21, and a feed pipe 23 is fixedly connected to one end of the top of the outer wall of the evaporation chamber 21. A steam pipe 24 is fixedly connected to one side of the outer wall of the evaporation chamber 21. The stirring component includes a motor 25 fixedly connected to the middle of one side of the outer wall of the evaporation chamber 21, and the output end of the motor 25 is fixedly connected to a transmission rod 26. A plurality of stirring blades 27 are fixedly connected to the outer wall of the transmission rod 26, and a plurality of support plates 28 are fixedly connected to the outer wall of the stirring blades 27. A high-frequency vibrator 29 is fixedly connected to one side of the outer wall of the support plate 28, and elastic plates 30 are rotatably connected to both sides of the outer wall of the support plate 28.

[0020] During operation, high-salt wastewater is poured into the evaporation chamber 21 through a feed pipe 23 provided at one end of the top of the outer wall of the evaporation chamber 21. The heating plate 22 provided at the bottom of the inner wall of the evaporation chamber 21 is started to heat and evaporate the high-salt wastewater in the evaporation chamber 21. By arranging a motor 25 in the middle of one side of the outer wall of the evaporation chamber 21, the driving rod 26 provided at the output end is driven by the motor 25. By arranging a number of uniformly arranged stirring vanes 27 on the outer wall of the driving rod 26, the stirring vanes 27 are used to stir the high-salt wastewater in the evaporation chamber 21, so that the high-salt wastewater is evenly heated, and precipitation of high-salt crystals in the high-salt wastewater is avoided, so as to prevent adhesion to the inner wall of the evaporation chamber 21. By arranging a support plate 28 on the outer wall of the stirring vane 27 and elastic plates 30 on both sides of the outer wall of the support plate 28, the elastic plates 30 are used to continuously and repeatedly scrape the inner wall of the evaporation chamber 21, and scrape off the high-salt crystals adhering to the inner wall of the evaporation chamber 21. Since high-salt crystals are likely to adhere to the surface of the stirring vane 27 during the evaporation of high-salt wastewater, in order to prevent high-salt crystals from accumulating on the surface of the stirring vane 27, a high-frequency vibrator 29 is arranged on one side of the outer wall of the support plate 28. The high-frequency vibrator 29 is used to make the stirring vane 27 generate high-frequency and slight vibrations, which can avoid high-salt crystals from adhering to the surface of the stirring vane 27 while not affecting the rotation of the driving rod 26 driving the stirring vane 27. As the high-salt wastewater is continuously heated, a large amount of water vapor is generated in the wastewater. By arranging a steam pipe 24 on one side of the outer wall of the evaporation chamber 21, the steam is discharged through the steam pipe 24. After the excess water in the high-salt wastewater is evaporated and discharged, there is still some highly viscous concentrated liquid remaining inside the high-salt crystals stored in the evaporation chamber 21, which is difficult to be evaporated and discharged through the heating plate 22. At this time, a discharge pipe 20 is arranged at one end of the bottom of the evaporation chamber 21, and the high-salt crystals are slowly discharged into the treatment main body 1 through the discharge pipe 20. Subsequently, the air supply chamber 8 is started, the inhaled air is heated to 120 degrees, and the hot air is sent into the shunt chamber 10 through the exhaust pipe 9 provided at the output end of the air supply chamber 8. By arranging a number of air supply pipes 11 on the inner wall of the shunt chamber 10, the hot air is blown along the air supply pipes 11 towards the rotating shaft ring 3, and the hot air fills the inner cavity of the treatment main body 1 to heat the outer wall of the guiding pipe 13. At this time, the high-salt crystals fall onto the surface of the sieve 6. The feeding plate 4 arranged on the inner wall of the rotating shaft ring 3 is used to extrude the high-salt crystals, and the high-salt crystals fall into the blanking bin 2 through the gaps of the sieve 6. The small batches of high-salt crystals enter the guiding pipe 13 along the blanking bin 2 and are discharged into the discharge bin 7 arranged at the bottom of the treatment main body 1 in batches through the guiding pipe 13. During this process, when the high-salt crystals fall along the guiding pipe 13, since the inner diameter of the guiding pipe 13 is small and the high-salt crystals contain highly viscous concentrated liquid, the high-salt crystals are likely to adhere to the inner wall of the guiding pipe 13. At this time, the high-temperature air is discharged into the guiding pipe 13 through the air supply disc 14. Combined with the high temperature of the guiding pipe 13 itself, the high-salt crystals adhering to the inner wall of the guiding pipe 13 are quickly heated, so that the distance between molecules in the highly viscous concentrated liquid becomes larger, and the viscosity of the highly viscous concentrated liquid is weakened until the flow resistance is lost.Thus, the purpose of completely drying the high-salt crystals is achieved.

[0021] The material distribution component includes a blanking bin 2 fixedly connected to the middle of the inner wall of the processing main body 1. A rotating shaft ring 3 is rotatably connected to the top of the blanking bin 2. A plurality of material deflecting plates 4 are fixedly connected to the inner wall of the rotating shaft ring 3. A plurality of arc-shaped plates 5 are fixedly connected to the outer wall of the rotating shaft ring 3. A screen 6 is fixedly connected to the top of one side of the inner wall of the blanking bin 2. The top of the screen 6 is slidably connected to the bottom of the material deflecting plate 4. The heating component includes a discharge bin 7 fixedly connected to the bottom of the processing main body 1. One end of the discharge bin 7 close to the processing main body 1 is fixedly connected to a blast bin 8. The output end of the blast bin 8 is fixedly connected to an exhaust pipe 9. One end of the exhaust pipe 9 is fixedly connected to a distribution bin 10. The outer wall of the distribution bin 10 is fixedly connected to the top of the inner cavity of the processing main body 1. A plurality of blast pipes 11 are fixedly connected to the inner wall of the distribution bin 10. The distribution component includes a distribution plate 12 fixedly connected to the bottom of the inner wall of the blanking bin 2. A plurality of guide pipes 13 are fixedly connected to the inner wall of the distribution plate 12. One end of the guide pipe 13 is fixedly connected to the bottom of the inner wall of the processing main body 1.

[0022] During operation, a lower material bin 2 is arranged in the middle of the inner wall of the processing body 1, a rotating shaft ring 3 is arranged on the top of the lower material bin 2, and a plurality of arc plates 5 are arranged on the outer wall of the rotating shaft ring 3. When the blast chamber 8 extracts air and heats the air to 120 degrees, the high-temperature hot air passes through the exhaust pipe 9 arranged at the output end of the blast chamber 8 and enters the diversion chamber 10. The diversion chamber 10 is used to divert the high-temperature hot air and discharge it along the plurality of blast pipes 11 arranged on the inner wall of the diversion chamber 10. Since the exhaust end of the blast pipe 11 is directly facing the arc plate 5, when the high-temperature hot air is discharged from the blast pipe 11, it blows directly to the arc plate 5, so that the arc plate 5 drives the rotating shaft ring 3 to enter the diversion chamber 10. The lower silo 2 rotates, and since a screen 6 is arranged on the top of one side of the inner wall of the lower silo 2, when the high-salt crystals fall onto the surface of the screen 6, the high-salt crystals on the surface of the screen 6 are stirred by a plurality of material-dispensing plates 4 arranged on the inner wall of the rotating shaft ring 3. Since the bottom of the material-dispensing plate 4 is in a chamfered right angle shape, the material-dispensing plate 4 squeezes the high-salt crystals on the surface of the screen 6 during the rotation process, so that the high-salt crystals fall into the lower silo 2 in small batches multiple times along the holes of the screen 6. Since the high-salt crystals contain high-viscosity concentrated liquid and are affected by the hot air discharged from the blast pipe 11, the temperature in the lower silo 2 is relatively high, and the high-salt crystal clusters are attached to the surface due to their small size. The high-viscosity concentrated liquid quickly loses its viscosity under the heating of the lower silo 2, thereby preventing the high-salt crystal clusters from sticking to each other. At this time, a dividing plate 12 is arranged at the bottom of the inner wall of the lower silo 2, and a number of small-amplitude wave blocks are arranged on the surface of the dividing plate 12. When the high-salt crystal clusters fall from the screen 6 to the inclined surface at the bottom of the lower silo 2, they are pulled by the inclined surface to collide with the wave blocks on the surface of the dividing plate 12, and the high-salt crystal clusters are broken and fall into the guide pipe 13 along the holes arranged on the surface of the dividing plate 12. As the hot air discharged from the blast pipe 11 drives the rotating shaft ring 3 to rotate, the residual heat generated by the high-temperature hot air is used to The lower bin 2 and the guide tube 13 in the processing body 1 are heated. Since the inner diameter of the guide tube 13 is relatively narrow, when the high-temperature hot air heats the surface of the guide tube 13, the heat can be more evenly distributed in the guide tube 13, so that the high-salt crystals entering the guide tube 13 can be evenly heated in the guide tube 13, and the high-viscosity concentrated liquid in the high-salt crystals can be more carefully dried, thereby achieving the purpose of keeping the high-salt crystals dry and avoiding sticking, further solving the problem of the traditional high-salt wastewater evaporation and crystallization device being difficult to effectively peel off due to the accumulation of high-salt crystals after the high-salt wastewater evaporates during use.

[0023] The guide component includes a ventilation plate 14 fixedly connected to the middle part of the inner wall of the lower material bin 2, and a plurality of ventilation pipes 15 are fixedly connected to the bottom of the ventilation plate 14. The circulation component includes a centrifugal fan 16 fixedly connected to the top of the discharge bin 7 away from the end of the blast bin 8, and the input end of the centrifugal fan 16 is fixedly connected to an electric heating pipe 17, one end of the electric heating pipe 17 is fixedly connected to an air intake pipe 18, and one end of the air intake pipe 18 is fixedly connected to the bottom of one side of the outer wall of the processing body 1, the top of the centrifugal fan 16 is fixedly connected to an air guide hose 19, and the outer wall of the air guide hose 19 passes through the processing body 1 and the lower material bin 2, and one end of the air guide hose 19 is fixedly connected to one side of the outer wall of the ventilation plate 14.

[0024] During operation, a centrifugal fan 16 is arranged at one end of the top of the discharge bin 7 away from the blast bin 8, the centrifugal fan 16 is started, an electric heating pipe 17 is arranged at its input end, and an air intake pipe 18 is arranged at one end of the electric heating pipe 17, the high-temperature hot air in the processing body 1 is recovered by the air intake pipe 18, and the high-temperature hot air is secondary heated by the electric heating pipe 17, so that the circulating air is heated to 220 degrees and enters the centrifugal fan 16 for pressurization, and an air guide hose 19 is arranged at the output end of the centrifugal fan 16 so that the pressurized high-temperature hot air is The hot air flows along the air guide hose 19 into the vent plate 14 provided in the middle of the inner wall of the lower silo 2. A plurality of vent pipes 15 are provided at the bottom of the vent plate 14. The number of vent pipes 15 corresponds to the number of guide pipes 13. The vent pipes 15 are located inside the guide pipe 13 and are not connected to the guide pipe 13. An exhaust port is provided at the bottom of one side of the outer wall of the vent pipe 15. The bottom of the inner cavity of the vent pipe 15 is conical. When the high salt crystals flow into the guide pipe 13 along the gap between the vent pipe 15 and the material distribution plate 12, The high-temperature pressurized hot air is discharged into the guide pipe 13 by using the vent pipe 15. On the one hand, it is convenient to blow away the high-salt crystals that fall into the guide pipe 13, so that the gaps between the crystals are increased, and it is convenient to use the heat in the guide pipe 13 to thoroughly dry the surface of the crystals. On the other hand, since the high-temperature hot air is pressurized, the circulation speed is faster. When the high-temperature hot air is discharged from the vent pipe 15, it rushes to the conical block set at the bottom of the inner cavity of the vent pipe 15, so that the high-temperature steam is ejected from the opening of the vent pipe 15 and forms a wind mast, which is helpful to blow away the high-salt crystals. At the same time, the high-temperature hot air is moved along the inner wall of the guide pipe 13 to clean up some high-salt crystals attached to the inner wall of the guide pipe 13, keep the inner wall of the guide pipe 13 smooth, and avoid high-salt crystals adhering to the inner wall of the guide pipe 13, which causes the guide pipe 13 to be blocked. This further solves the problem that it is difficult to effectively and meticulously process high-salt crystals in batches during the use of traditional high-salt wastewater evaporation and crystallization devices, resulting in residual high-viscosity concentrate in the high-salt crystals, which easily causes the pipeline to be blocked when the high-salt crystals are discharged.

[0025] An operation method of a high-salt wastewater evaporation and crystallization device, which uses the above-mentioned high-salt wastewater evaporation and crystallization device, is as follows: S1: Pour the wastewater into the evaporation chamber 21 from the feed pipe 23, evaporate the excess water in the wastewater by using the heating plate 22, and discharge it from the steam pipe 24. Then, send it into the treatment main body 1 through the discharge pipe 20 arranged at one end of the bottom of the evaporation chamber 21. Use the material distribution component to break up the high-salt crystals, cooperate with the heating component to pre-treat the high-salt crystals, and then use the circulation component to clean the high-salt crystals more carefully; S2: The material distribution component sets a number of arc-shaped plates 5 on the outer wall of the rotating shaft ring 3. When the high-temperature hot air is discharged through the air blowing pipe 11, it blows the arc-shaped plates 5 to make the rotating shaft ring 3 rotate, and uses a number of feeding plates 4 arranged on the inner wall of the rotating shaft ring 3 to squeeze the high-salt crystals out of the surface of the sieve mesh 6, so as to complete the separation of the high-salt crystal clusters; S3: The heating component heats the air to 120 degrees through the air blowing chamber 8, and then sends it into the shunt chamber 10 through the exhaust pipe 9. By setting a number of air blowing pipes 11 on the inner wall of the shunt chamber 10, while blowing out the high-temperature hot air through the air blowing pipes 11, it pushes the rotating shaft ring 3 to rotate, and uses the high-temperature hot air to heat the feeding bin 2 and the guiding pipe 13 in the treatment main body 1; S4: The circulation component sucks the high-temperature hot air in the treatment main body 1 through the centrifugal fan 16, and uses the electric heating pipe 17 arranged at one end of the suction pipe 18 to reheat the high-temperature hot air until the air temperature rises to 220 degrees. Then, it is discharged into the ventilation disc 14 through the air guiding hose 19 arranged at the output end of the centrifugal fan 16, and uses the ventilation pipe 15 to reheat the inside of the guiding pipe 13 again.

[0026] Next, specifically describe the working principle of the high-salt wastewater evaporation and crystallization device and its operation method.

[0027] As Figures 1 - 10As shown in the figure, pour the high-salt wastewater into the evaporation chamber 21 from one end at the top of the outer wall of the evaporation chamber 21 through the feed pipe 23. Start the heating plate 22 provided at the bottom of the inner wall of the evaporation chamber 21 to heat and evaporate the high-salt wastewater in the evaporation chamber 21. Set a motor 25 in the middle of one side of the outer wall of the evaporation chamber 21, use the motor 25 to drive the transmission rod 26 provided at the output end, and set a number of evenly arranged stirring blades 27 on the outer wall of the transmission rod 26, so as to use the stirring blades 27 to stir the high-salt wastewater in the evaporation chamber 21, making the high-salt wastewater evenly heated and avoiding precipitation of high-salt crystals in the high-salt wastewater, thus adhering to the inner wall of the evaporation chamber 21. Set a support plate 28 on the outer wall of the stirring blade 27, and set elastic plates 30 on both sides of the outer wall of the support plate 28, and use the elastic plates 30 to continuously scrape and wash the inner wall of the evaporation chamber 21, scraping off the high-salt crystals adhering to the inner wall of the evaporation chamber 21. As the high-salt wastewater is continuously heated, a large amount of water vapor is generated in the wastewater. Set a steam pipe 24 on one side of the outer wall of the evaporation chamber 21, and use the steam pipe 24 to discharge the steam. As the excess water in the high-salt wastewater is evaporated and discharged, there is still some highly viscous concentrated liquid remaining inside the high-salt crystals remaining in the evaporation chamber 21, which is difficult to be evaporated and discharged through the heating plate 22. At this time, set a discharge pipe 20 at one end of the bottom of the evaporation chamber 21, and use the discharge pipe 20 to slowly discharge the high-salt crystals into the treatment main body 1. Then start the air blast chamber 8, heat the inhaled air to 120 degrees, and send the hot air into the shunt chamber 10 through the exhaust pipe 9 provided at the output end of the air blast chamber 8. Use a number of air blast pipes 11 provided on the inner wall of the shunt chamber 10 to make the hot air blow along the air blast pipes 11 towards the rotating shaft ring 3, and make the hot air fill the inner cavity of the treatment main body 1 to heat the outer wall of the guiding pipe 13. At this time, the high-salt crystals fall onto the surface of the sieve 6, use the feeding plate 4 provided on the inner wall of the rotating shaft ring 3 to squeeze the high-salt crystals, and make the high-salt crystals fall into the blanking bin 2 through the gaps of the sieve 6, so that the high-salt crystals in small batches enter the guiding pipe 13 along the blanking bin 2, and are discharged into the discharge bin 7 provided at the bottom of the treatment main body 1 in batches through the guiding pipe 13. During this process, when the high-salt crystals fall along the guiding pipe 13, due to the small inner diameter of the guiding pipe 13 and the high-salt crystals containing highly viscous concentrated liquid, the high-salt crystals are likely to adhere to the inner wall of the guiding pipe 13. At this time, use the air vent disk 14 to discharge high-temperature air into the guiding pipe 13, and cooperate with the high temperature of the guiding pipe 13 itself to heat the high-salt crystals adhering to the inner wall of the guiding pipe 13 quickly, so that the distance between molecules in the highly viscous concentrated liquid becomes larger, and the viscosity of the highly viscous concentrated liquid weakens until the flow resistance is lost, so as to achieve the purpose of completely drying the high-salt crystals.

[0028] The above generally describes the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
