[0024] A method for operating a high-salt wastewater evaporation and crystallization device, which uses the above-mentioned high-salt wastewater evaporation and crystallization device, is as follows:

[0025] S1: Pour wastewater into the evaporation chamber from the feed pipe, use the heating plate to evaporate excess water in the wastewater and discharge it from the steam pipe. Then, it is fed into the treatment body through the discharge pipe set at one end of the bottom of the evaporation chamber.

[0029] Due to the adoption of the above technical solution, the present invention has the following technical advancements compared to the prior art:

[0030] 1. The present invention provides a high-salt wastewater evaporation and crystallization device and an operating method thereof. The high-salt crystals on the surface of the screen are stirred by a plurality of stripping plates arranged on the inner wall of a rotating shaft ring. Since the bottom of the stripping plate is in a chamfered right-angled shape, the stripping plate causes the high-salt crystals to fall into a lower hopper in small batches along the holes of the screen during rotation. The temperature in the lower hopper is relatively high, and the high-salt crystal clusters, due to their small size, cause the high-viscosity concentrated liquid attached to their surfaces to quickly lose viscosity under the heating of the lower hopper, thereby preventing the high-salt crystal clusters from sticking to each other. This further solves the problem of the traditional high-salt wastewater evaporation and crystallization device in which, during use, the high-salt crystals accumulate with each other after the high-salt wastewater evaporates, making it difficult to effectively peel off the high-viscosity concentrated liquid inside.

[0031] 2. The present invention provides a high-salt wastewater evaporation and crystallization device and an operation method thereof. A plurality of vent pipes are arranged at the bottom of the vent plate, and the number of the vent pipes corresponds to the number of guide pipes. The vent pipes are located inside the guide pipe and are not connected to the guide pipe. An exhaust port is arranged at the bottom of one side of the outer wall of the vent pipe, and the bottom of the inner cavity of the vent pipe is tapered, so that the high-temperature hot air moves along the inner wall of the guide pipe, and part of the high-salt crystals attached to the inner wall of the guide pipe are cleaned, the inner wall of the guide pipe is kept smooth, and the high-salt crystals are prevented from adhering to the inner wall of the guide pipe, causing the guide pipe to be blocked. This further solves the problem that the traditional high-salt wastewater evaporation and crystallization device is difficult to effectively and meticulously process the high-salt crystals in batches during use, 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.

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0044] like Figures 1 to 10 As shown, a high-salt wastewater evaporation and crystallization device described in an embodiment of the present invention includes a processing body, a material distribution component for discharging pretreated salt crystals in batches; a heating component for heating the high-salt crystals in the pipeline; a diversion component for evaporating the high-viscosity concentrated liquid in the salt crystals; a guiding component for preventing the high-salt crystals from sticking to the pipeline; a circulation component for recycling the air heated by the pipeline and heating it for reuse; 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 body 1, and one end of the discharge pipe 20 is fixedly connected to The evaporation bin 21 has a heating plate 22 fixedly connected to the bottom of the inner wall of the evaporation bin 21, and a feed pipe 23 fixedly connected to one end of the top of the outer wall of the evaporation bin 21, and a steam pipe 24 fixedly connected to one side of the outer wall of the evaporation bin 21. The stirring assembly includes a motor 25 fixedly connected to the middle of one side of the outer wall of the evaporation bin 21, and the output end of the motor 25 is fixedly connected to a transmission rod 26, the outer wall of the transmission rod 26 is fixedly connected to a plurality of stirring blades 27, and the outer wall of the stirring blade 27 is fixedly connected to a plurality of support plates 28, one side of the outer wall of the support plate 28 is fixedly connected to a high-frequency vibrator 29, and both sides of the outer wall of the support plate 28 are rotatably connected to elastic plates 30.

[0045] During operation, high-salt wastewater is poured into the evaporation bin 21 from a feed pipe 23 provided at one end of the top of the outer wall of the evaporation bin 21, and the heating plate 22 provided at the bottom of the inner wall of the evaporation bin 21 is started to heat and evaporate the high-salt wastewater in the evaporation bin 21. A motor 25 is provided in the middle of one side of the outer wall of the evaporation bin 21, and the motor 25 drives the transmission rod 26 provided at the output end. A plurality of evenly arranged stirring blades 27 are provided on the outer wall of the transmission rod 26, so that the high-salt wastewater in the evaporation bin 21 is stirred by the stirring blades 27, so that the high-salt wastewater is heated evenly, and high-salt crystals in the high-salt wastewater are prevented from precipitating and adhering to the inner wall of the evaporation bin 21. A support plate 28 is provided on the outer wall of the stirring blade 27, and elastic plates 30 are provided on both sides of the outer wall of the support plate 28. The plate 30 continuously and repeatedly scrapes the inner wall of the evaporation bin 21 to scrape off the high-salt crystals attached to the inner wall of the evaporation bin 21. Since the high-salt wastewater is easily attached to the surface of the stirring piece 27 during the evaporation process, in order to prevent the high-salt crystals from accumulating on the surface of the stirring piece 27, a high-frequency vibrator 29 is provided on one side of the outer wall of the support plate 28. The high-frequency vibrator 29 is used to make the stirring piece 27 generate a high-frequency slight vibration. While not affecting the rotation of the stirring piece 27 driven by the transmission rod 26, the high-salt crystals are prevented from adhering to the surface of the stirring piece 27. As the high-salt wastewater is continuously heated, a large amount of water vapor is generated in the wastewater. By providing a steam pipe 24 on one side of the outer wall of the evaporation bin 21, the steam is discharged by the steam pipe 24, and as the excess water in the high-salt wastewater is discharged, the steam is discharged. After the water is discharged through evaporation, some high-viscosity concentrated liquid still remains inside the high-salt crystals in the evaporation bin 21, which is difficult to be evaporated and discharged through the heating plate 22. At this time, a discharge pipe 20 is set at one end of the bottom of the evaporation bin 21, and the high-salt crystals are slowly discharged into the processing body 1 through the discharge pipe 20. Then the blast bin 8 is started to heat the inhaled air to 120 degrees Celsius, and the hot air is sent into the diversion bin 10 through the exhaust pipe 9 set at the output end of the blast bin 8. The several blast pipes 11 set on the inner wall of the diversion bin 10 are used to make the hot air blow along the blast pipe 11 to the rotating shaft ring 3, and the hot air fills the inner cavity of the processing body 1 and heats the outer wall of the guide pipe 13. At this time, the high-salt crystals fall onto the surface of the screen 6 and are heated by the exhaust pipe 9 set on the inner wall of the rotating shaft ring 3. The stripping plate 4 squeezes the high-salt crystals and makes them fall into the lower hopper 2 through the gaps in the screen 6, so that small batches of high-salt crystals follow the lower hopper 2 into the guide pipe 13 and are discharged in batches into the discharge hopper 7 provided at the bottom of the processing body 1 through the guide pipe 13. In this process, when the high-salt crystals fall along the guide pipe 13, due to the small diameter of the guide pipe 13 and the high-viscosity concentrated liquid contained in the high-salt crystals, the high-salt crystals are easily attached to the inner wall of the guide pipe 13. At this time, the vent plate 14 is used to discharge high-temperature air into the guide pipe 13. Combined with the high temperature of the guide pipe 13 itself, the high-salt crystals attached to the guide pipe 13 are quickly heated, thereby increasing the distance between molecules in the high-viscosity concentrated liquid and reducing the viscosity of the high-viscosity concentrated liquid.Until the flow resistance is lost, thus achieving the purpose of completely drying the high salt crystals.

[0046] The material distribution component includes a lower material bin 2 fixedly connected to the middle of the inner wall of the processing body 1, the top of the lower material bin 2 is rotatably connected to a rotating shaft ring 3, and the inner wall of the rotating shaft ring 3 is fixedly connected to a plurality of material stripping plates 4, and the outer wall of the rotating shaft ring 3 is fixedly connected to a plurality of arc-shaped plates 5, the top of one side of the inner wall of the lower material bin 2 is fixedly connected to a screen 6, and the top of the screen 6 is slidably connected to the bottom of the material stripping plate 4, the heating component includes a discharge bin 7 fixedly connected to the bottom of the processing body 1, and the top of the discharge bin 7 is close to one end of the processing body 1 It is fixedly connected to a blast bin 8, the output end of the blast bin 8 is fixedly connected to an exhaust pipe 9, and one end of the exhaust pipe 9 is fixedly connected to a diversion bin 10, the outer wall of the diversion bin 10 is fixedly connected to the top of the inner cavity of the processing body 1, and the inner wall of the diversion bin 10 is fixedly connected to a number of blast pipes 11, the diversion assembly includes a distribution plate 12 fixedly connected to the bottom of the inner wall of the lower hopper 2, and the inner wall of the distribution plate 12 is fixedly connected to a number of guide pipes 13, and one end of the guide pipe 13 is fixedly connected to the bottom of the inner wall of the processing body 1.

[0047] During operation, a lower material bin 2 is provided in the middle of the inner wall of the processing body 1, and a rotating shaft ring 3 is provided on the top of the lower material bin 2, and a plurality of curved plates 5 are provided on the outer wall of the rotating shaft ring 3. When the blast chamber 8 extracts air and heats the air to 120 degrees Celsius, the high-temperature hot gas passes through the exhaust pipe 9 provided 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 gas and discharge it along the plurality of blast pipes 11 provided on the inner wall of the diversion chamber 10. Since the exhaust end of the blast pipe 11 is directly facing the curved plate 5, when the high-temperature hot gas is discharged from the blast pipe 11, it blows directly to the curved plate 5, thereby causing the curved plate 5 to drive the rotating shaft ring 3. The lower hopper 2 is rotated. Since a screen 6 is provided on the top of one side of the inner wall of the lower hopper 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 stripping plates 4 provided on the inner wall of the rotating shaft ring 3. Since the bottom of the stripping plate 4 is in a right-angled shape, the stripping 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 hopper 2 in small batches 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 hopper 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 hopper 2, thereby preventing the high-salt crystal clusters from sticking to each other. At this time, a dividing plate 12 is set at the bottom of the inner wall of the lower hopper 2, and a number of small-amplitude wave blocks are set 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 hopper 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 set 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 discharge 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 dried more carefully, thereby achieving the purpose of keeping the high-salt crystals dry and avoiding sticking. This further solves the problem that in the use of traditional high-salt wastewater evaporation and crystallization devices, after the high-salt wastewater evaporates, the high-salt crystals accumulate with each other, resulting in the high-viscosity concentrated liquid inside being difficult to effectively peel off.

[0048] The guide assembly includes a ventilation plate 14 fixedly connected to the middle 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 assembly 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.

[0049] During operation, a centrifugal fan 16 is provided 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 provided at its input end, and an air intake pipe 18 is provided 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 Celsius and enters the centrifugal fan 16 for pressurization, and an air guide hose 19 is provided at the output end of the centrifugal fan 16 so that the pressurized hot air is discharged. The high-temperature 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 hopper 2. A plurality of vent pipes 15 are provided at the bottom of the vent plate 14, and the number of the vent pipes 15 corresponds to the number of the 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, and the bottom of the inner cavity of the vent pipe 15 is tapered. When high salt crystals flow along the gap between the vent pipe 15 and the dividing plate 12 into the guide pipe 13, the high-temperature hot air flows along the air guide hose 19 into the vent plate 14. When the hot air is discharged from the vent pipe 15, the high-temperature pressurized hot air is discharged into the guide pipe 13. On the one hand, it is easy 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 helps to blow away the high-salt crystals. During the separation, the high-temperature hot air is moved along the inner wall of the guide tube 13 to clean up some high-salt crystals attached to the inner wall of the guide tube 13, keep the inner wall of the guide tube 13 smooth, and avoid high-salt crystals adhering to the inner wall of the guide tube 13, causing the guide tube 13 to be blocked. This further solves the problem that the traditional high-salt wastewater evaporation and crystallization device is difficult to effectively and meticulously process the high-salt crystals in batches during use, 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.

[0050] A method for operating a high-salt wastewater evaporation and crystallization device, which uses the above-mentioned high-salt wastewater evaporation and crystallization device, is as follows:

[0051] S1: Pour wastewater from the feed pipe 23 into the evaporation chamber 21, evaporate excess water in the wastewater using the heating plate 22, and discharge it from the steam pipe 24. The wastewater is then fed into the treatment body 1 through the discharge pipe 20 provided at one end of the bottom of the evaporation chamber 21. The high-salt crystals are broken up using the distributing component, pre-treated with the heating component, and then cleaned more carefully using the circulation component.

[0052] S2: The material separation component is provided with a plurality of curved plates 5 on the outer wall of the rotating shaft ring 3. When the high-temperature hot air is discharged through the blast pipe 11, the curved plates 5 are blown to rotate the rotating shaft ring 3. The plurality of material stripping plates 4 provided on the inner wall of the rotating shaft ring 3 are used to squeeze the high-salt crystals from the surface of the screen 6, so that the high-salt crystal clusters are separated;

[0053] S3: The heating component heats the air to 120 degrees Celsius through the blast chamber 8 and then sends it into the diversion chamber 10 through the exhaust pipe 9. A number of blast pipes 11 are provided on the inner wall of the diversion chamber 10. The blast pipes 11 blow out the high-temperature hot air while driving the rotating shaft ring 3 to rotate, and the high-temperature hot air is used to heat the lower bin 2 and the guide pipe 13 in the processing body 1;

[0054] S4: The circulation component draws the high-temperature hot air in the processing body 1 into the air intake pipe 18 through the centrifugal fan 16, and uses the electric heating tube 17 provided at one end of the air intake pipe 18 to reheat the high-temperature hot air until the air temperature rises to 220 degrees Celsius. It is then discharged into the ventilation disk 14 through the air guide hose 19 provided at the output end of the centrifugal fan 16, and the guide pipe 13 is heated again by the ventilation pipe 15.

[0055] The working principle of the high-salt wastewater evaporation crystallization device and its operation method are described in detail below.

[0056] like Figures 1-10As shown, high-salt wastewater is poured into the evaporation chamber 21 from a feed pipe 23 provided at one end of the top of the outer wall of the evaporation chamber 21, and 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. A motor 25 is provided in the middle of one side of the outer wall of the evaporation chamber 21, and the motor 25 drives the transmission rod 26 provided at the output end. A plurality of evenly arranged stirring blades 27 are provided on the outer wall of the transmission rod 26, so that the high-salt wastewater in the evaporation chamber 21 is stirred by the stirring blades 27, so that the high-salt wastewater is heated evenly, and high-salt crystals in the high-salt wastewater are prevented from precipitating and adhering to the inner wall of the evaporation chamber 21. A support is provided on the outer wall of the stirring blade 27. The plate 28 is provided with elastic plates 30 on both sides of the outer wall of the support plate 28, and the inner wall of the evaporation chamber 21 is repeatedly scraped and cleaned by the elastic plates 30 to scrape off the high-salt crystals attached 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. A steam pipe 24 is provided on one side of the outer wall of the evaporation chamber 21 to discharge the steam. As the excess water in the high-salt wastewater is discharged through evaporation, some high-viscosity concentrated liquid still remains inside the high-salt crystals 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 provided at one end of the bottom of the evaporation chamber 21 to discharge the water through the discharge pipe. 20 The high-salt crystals are slowly discharged into the processing body 1, and then the blast chamber 8 is started to heat the inhaled air to 120 degrees Celsius, and the hot air is sent to the diversion chamber 10 through the exhaust pipe 9 set at the output end of the blast chamber 8. The hot air is blown along the blast pipes 11 to the rotating shaft ring 3 by using the multiple blast pipes 11 set on the inner wall of the diversion chamber 10, and the hot air is filled with the inner cavity of the processing body 1 and heats the outer wall of the guide pipe 13. At this time, the high-salt crystals fall onto the surface of the screen 6, and the stripping plate 4 set on the inner wall of the rotating shaft ring 3 is used to squeeze the high-salt crystals and make them fall into the lower hopper 2 through the gaps in the screen 6, so that small batches of high-salt crystals flow along the lower hopper 2. The high-salt crystals enter the guide pipe 13 and are discharged in batches into the discharge bin 7 provided at the bottom of the processing body 1 through the guide pipe 13. During this process, when the high-salt crystals fall along the guide pipe 13, due to the small diameter of the guide pipe 13 and the high-viscosity concentrated liquid contained in the high-salt crystals, the high-salt crystals are easily attached to the inner wall of the guide pipe 13. At this time, the vent plate 14 is used to discharge high-temperature air into the guide pipe 13. Combined with the high temperature of the guide pipe 13 itself, the high-salt crystals attached to the guide pipe 13 are rapidly heated, thereby increasing the distance between the molecules in the high-viscosity concentrated liquid and reducing the viscosity of the high-viscosity concentrated liquid until the flow resistance is lost, thereby achieving the purpose of completely drying the high-salt crystals.

Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
