Description

Technical Field

[0001] This invention belongs to the field of purification device technology, specifically a nylon ATY oil wastewater cooling and purification device and its working method. Background Technology

[0002] Nylon ATY oil wastewater is an industrial wastewater containing a variety of organic pollutants, mainly originating from the production process of nylon fibers. The pollutants in this wastewater include monomers, additives, oils, and other organic compounds such as amines, esters, ethers, and phenols. Due to the high biotoxicity and chemical stability of these pollutants, nylon ATY oil wastewater poses a significant threat to the environment and ecology.

[0003] The main purpose of wastewater treatment is to reduce the content of harmful substances in wastewater to meet the national or local emission standards, thereby reducing harm to the environment. There are various methods for treating nylon ATY oil wastewater, including physical, chemical and biological methods. Depending on the characteristics of the wastewater and the treatment requirements, different treatment methods can be selected or multiple methods can be combined to achieve the best treatment effect.

[0004] Because the wastewater from nylon ATY oil contains particulate impurities and suspended solids, it not only risks clogging the evaporator but also affects the equipment's wastewater treatment efficiency. Therefore, the wastewater is allowed to stand for a period of time before treatment. However, the standing time for wastewater usually ranges from several hours to several days, which is quite long and leads to low wastewater treatment efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a nylon ATY oil wastewater cooling and purification device and its working method to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a nylon ATY oil wastewater cooling and purification device, comprising a main body of equipment, a cabinet door hinged to one side of the main body of equipment, an evaporator and a cooling tank arranged inside the main body of equipment, the evaporator and the cooling tank being connected by a connecting pipe, an inlet pipe fixedly installed on one side of the evaporator, a first outlet pipe fixedly connected to the bottom end of the evaporator, and a second outlet pipe fixedly installed at the bottom end of the cooling tank;

[0007] The equipment uses low-temperature evaporation of nylon ATY oil wastewater, keeping the evaporation temperature between 37-50℃. This reduces the hardening effect of the dirt, making it less prone to scale formation. Both the equipment and the effluent are below 50℃, eliminating any safety hazards such as burns.

[0008] The evaporator has a first liquid storage chamber and a second liquid storage chamber inside, and a partition is provided between the first liquid storage chamber and the second liquid storage chamber. The partition is fixedly installed on the inner wall of the evaporator. A suction pipe is provided inside the second liquid storage chamber. A moving component is provided at the bottom end of the suction pipe. The suction pipe passes through the inner wall of the partition and extends into the interior of the first liquid storage chamber. A suction pump is installed at the top end of the suction pipe. A cleaning component is provided inside the second liquid storage chamber.

[0009] The evaporator is divided into two chambers by a partition, which avoids the problem that the wastewater usually needs to stand for several hours to several days, resulting in low wastewater treatment efficiency. While the wastewater in the first storage chamber is evaporated at low temperature, the wastewater in the second storage chamber settles, thus improving the wastewater treatment efficiency.

[0010] As a further technical solution of the present invention, an observation window is provided on one side of the evaporator.

[0011] When discharging wastewater, the specific amount of wastewater discharged can be observed, which makes it easier to control the discharge volume; during the wastewater settling process, the settling effect of the wastewater inside the second storage chamber can be observed, which facilitates subsequent treatment.

[0012] As a further technical solution of the present invention, the moving component includes a fixing plate disposed at the bottom end of the suction tube, the fixing plate being fixedly connected to the suction tube, a connecting rod being fixedly installed at the top end of the fixing plate, the connecting rod being slidably installed on the inner wall of the evaporator, a connecting plate being fixedly installed at the top end of the connecting rod, the end of the connecting plate away from the connecting rod being disposed on the outer wall of the threaded rod, and a motor being installed at the top end of the threaded rod.

[0013] When it is necessary to adjust the position of the bottom end of the suction pipe, the motor can be started by controlling the PLC to drive the threaded rod to rotate. The rotation of the threaded rod drives the connecting plate to move, the movement of the connecting plate drives the connecting rod to move, the movement of the connecting rod drives the fixed plate to move, and the movement of the fixed plate drives the suction pipe to move. This changes the position of the bottom end of the suction pipe inside the second liquid storage chamber, thereby sucking up wastewater at different depths. By adjusting the suction depth of the suction pipe, impurities in the wastewater can be avoided, which helps to improve the clarity of the wastewater, reduce the risk of clogging the evaporator, and improve the treatment effect.

[0014] As a further technical solution of the present invention, the cleaning component includes a scraper disposed inside the second liquid storage chamber, a rotating plate fixedly installed at the bottom end of the scraper, a first gear meshing with the inside of the rotating plate, a first connecting shaft fixedly installed at the bottom end of the first gear, a second bevel gear fixedly connected at the bottom end of the first connecting shaft, a first bevel gear meshing with the bottom end of the second bevel gear, a rotating shaft fixedly installed on one side of the first bevel gear, a power plate installed on the outer wall of the rotating shaft, and the power plate disposed inside the first liquid outlet pipe.

[0015] When discharging wastewater containing large particles and suspended solids from the second storage chamber, the rotation of the power plate drives the rotation of the rotating shaft, which in turn drives the rotation of the first bevel gear, which in turn drives the rotation of the second bevel gear. Salts in the water may precipitate out and adhere to the surface of the equipment, forming a scale wall that rotates to assist the discharge of wastewater from the bottom.

[0016] As a further technical solution of the present invention, the scraper is slidably attached to the inner wall of the second liquid storage chamber.

[0017] Not only can it assist in the discharge of wastewater containing large particles and suspended solids from the second liquid storage chamber, but it can also scrape the inner wall of the evaporator during rotation to prevent salts in the water from precipitating out and adhering to the equipment surface, forming scale. The scale layer can be removed by the rotation of the scraper, making it easier to keep the inside of the second liquid storage chamber clean.

[0018] As a further technical solution of the present invention, the rotating plate is rotatably installed on the inner wall of the first liquid outlet pipe, and a sealing gasket is installed between the rotating plate and the first liquid outlet pipe.

[0019] The material used to seal between the rotating plate and the first outlet pipe is usually made of soft materials such as rubber, silicone, or metal. Its function is to prevent wastewater leakage inside the evaporator and also to reduce noise and vibration.

[0020] As a further technical solution of the present invention, a second gear is meshed with the outer wall of the rotating plate, a locking block is slidably installed inside the second gear, the locking block is fixedly installed on the outer wall of the second connecting shaft, a motor is fixedly installed at the bottom end of the second connecting shaft, the motor is installed inside the fixed seat, and the fixed seat is fixedly installed at the bottom end of the evaporator.

[0021] As a further technical solution of the present invention, a third connecting shaft is fixedly installed at the bottom end of the second gear, the third connecting shaft is slidably installed on the outer wall of the second connecting shaft, and a movable plate is rotatably installed on the outer wall of the third connecting shaft, the movable plate being slidably installed inside the fixed base.

[0022] As a further technical solution of the present invention, a magnetic block is provided at the top of the movable plate, and the magnetic block is fixedly installed at the bottom of the evaporator.

[0023] A method for operating a nylon ATY oil-based wastewater cooling and purification device includes the following steps:

[0024] S1: First, a certain amount of wastewater is discharged into the second storage chamber through the inlet pipe. During discharge, the amount of wastewater discharged can be observed through the observation window.

[0025] S2: Then, allow the wastewater in the second storage chamber to settle. The settling effect of the wastewater can be observed through the observation window.

[0026] S3: Then, based on the sedimentation effect of the wastewater, choose whether to adjust the position of the bottom of the suction pipe. When adjustment is required, the motor can be started by controlling the PLC to drive the rotation of the threaded rod. The rotation of the threaded rod drives the movement of the connecting plate, the movement of the connecting plate drives the movement of the connecting rod, the movement of the connecting rod drives the movement of the fixed plate, and the movement of the fixed plate drives the movement of the suction pipe, changing the position of the suction pipe inside the second storage chamber.

[0027] S4: Then, by starting the suction pump, the wastewater that has settled in the second storage chamber is drawn into the first storage chamber.

[0028] S5: Then, the wastewater containing impurities in the second storage chamber is discharged through the connecting pipe by the control of the solenoid valve. During the discharge process, the wastewater drives the rotation of the power plate, which in turn drives the rotation of the rotating shaft. The rotation of the rotating shaft drives the rotation of the first bevel gear, which in turn drives the rotation of the second bevel gear. Salts in the water may precipitate and adhere to the surface of the equipment, forming a scale wall that rotates to assist the discharge of wastewater at the bottom.

[0029] S6: After the wastewater is discharged, a new batch of wastewater can be discharged into the second storage chamber through the inlet pipe for sedimentation, which is convenient for subsequent use;

[0030] S7: Finally, the wastewater is evaporated at low temperature in the evaporator. The steam is discharged into the cooling tank through the connecting pipe and condensed. The condensed liquid is discharged from the second liquid outlet pipe.

[0031] The beneficial effects of this invention are as follows:

[0032] 1. This invention uses equipment to perform low-temperature evaporation of nylon ATY oil wastewater, maintaining the evaporation temperature between 37-50℃. The low evaporation temperature reduces the hardening effect of dirt, making it less prone to scale formation. Both the equipment and the effluent are below 50℃, eliminating any safety hazards such as scalding. The evaporator is divided into two chambers by a partition, avoiding the problem of low wastewater treatment efficiency caused by the long settling time of wastewater, which typically ranges from several hours to several days. While the wastewater in the first storage chamber undergoes low-temperature evaporation, the wastewater in the second storage chamber settles, improving the wastewater treatment efficiency.

[0033] 2. This invention, through the setting of the moving component, allows for adjustment of the position of the bottom end of the suction pipe via PLC-controlled motor startup. This motor rotation drives the threaded rod, which in turn moves the connecting plate, which in turn moves the connecting rod, which in turn moves the fixing plate, which in turn moves the suction pipe. This changes the position of the bottom end of the suction pipe within the second storage chamber, thereby allowing for the suction of wastewater at different depths. This avoids issues caused by different batches of wastewater or varying settling times, which result in different settling depths of large particles and suspended solids. By adjusting the suction depth of the suction pipe, impurities in the wastewater can be avoided, improving wastewater clarity, reducing the risk of evaporator blockage, and enhancing treatment efficiency.

[0034] 3. By setting up the cleaning component, when the wastewater containing large particles and suspended solids in the second storage chamber is discharged, the rotation of the power plate drives the rotation of the rotating shaft, which in turn drives the rotation of the first bevel gear, which in turn drives the rotation of the second bevel gear. Salts in the water may precipitate out and adhere to the surface of the equipment, forming a scale wall, which rotates and assists in the discharge of wastewater at the bottom.

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Example 1

[0047] like Figures 1 to 9 As shown in the embodiment of the present invention, a nylon ATY oil wastewater cooling and purification device includes a main body 1, a cabinet door 2 hinged to one side of the main body 1, an evaporator 3 and a cooling tank 7 arranged inside the main body 1, the evaporator 3 and the cooling tank 7 are connected by a connecting pipe 6, an inlet pipe 4 is fixedly installed on one side of the evaporator 3, a first outlet pipe 5 is fixedly connected to the bottom end of the evaporator 3, and a second outlet pipe 8 is fixedly installed at the bottom end of the cooling tank 7.

[0048] The evaporator 3 has a first liquid storage chamber 11 and a second liquid storage chamber 12 inside. A partition 10 is provided between the first liquid storage chamber 11 and the second liquid storage chamber 12. The partition 10 is fixedly installed on the inner wall of the evaporator 3. A suction pipe 14 is provided inside the second liquid storage chamber 12. A moving component is provided at the bottom end of the suction pipe 14. The suction pipe 14 passes through the inner wall of the partition 10 and extends into the interior of the first liquid storage chamber 11. A suction pump 13 is installed at the top end of the suction pipe 14. A cleaning component is provided inside the second liquid storage chamber 12.

[0049] When it is necessary to cool and purify the wastewater of nylon ATY oil, a certain amount of wastewater is first discharged into the second storage chamber 12 through the inlet pipe 4. Then, the wastewater in the second storage chamber 12 is allowed to settle. After settling, the wastewater in the second storage chamber 12 is sucked into the first storage chamber 11 by starting the suction pump 13. Then, it is evaporated at low temperature through the evaporator 3. The steam is discharged into the cooling tank 7 through the connecting pipe 6 for condensation. The condensed liquid is discharged from the second outlet pipe 8.

[0050] The inlet pipe 4, the first outlet pipe 5, and the second outlet pipe 8 are all equipped with solenoid valves for control of the inlet and outlet of liquid.

[0051] Evaporator 3 is a low-temperature evaporator that uses refrigerant for evaporation.

[0052] If foam is generated during the evaporation process, an appropriate amount of defoamer can be added to eliminate the foam.

[0053] The equipment uses low-temperature evaporation of nylon ATY oil wastewater, keeping the evaporation temperature between 37-50℃. The low evaporation temperature reduces the hardening effect of the dirt, making it less likely to form scale. Both the equipment and the effluent are below 50℃, eliminating any safety hazards such as burns.

[0054] The evaporator 3 is divided into two chambers by the partition 10, which avoids the problem that the wastewater usually needs to stand for several hours to several days, which is a long time and leads to low wastewater treatment efficiency. When the wastewater in the first storage chamber 11 is evaporated at low temperature, the wastewater in the second storage chamber 12 settles, which improves the wastewater treatment efficiency.

[0055] like Figures 1 to 4 As shown, an observation window 9 is provided on one side of the evaporator 3.

[0056] The observation window 9 is made of transparent material, and a window corresponding to the position of the observation window 9 is opened on one side of the main body of the equipment. When wastewater is discharged, the specific amount of wastewater discharged can be observed, which is convenient for controlling the discharge volume. During the wastewater settling process, the settling effect of the wastewater in the second liquid storage chamber 12 can be observed, which is convenient for subsequent treatment.

[0057] like Figures 1 to 9 As shown, the moving assembly includes a fixing plate 15 disposed at the bottom end of the suction pipe 14. The fixing plate 15 is fixedly connected to the suction pipe 14. A connecting rod 16 is fixedly installed at the top end of the fixing plate 15. The connecting rod 16 is slidably installed on the inner wall of the evaporator 3. A connecting plate 17 is fixedly installed at the top end of the connecting rod 16. The end of the connecting plate 17 away from the connecting rod 16 is disposed on the outer wall of the threaded rod 18. A motor 19 is installed at the top end of the threaded rod 18.

[0058] By adjusting the position of the bottom of the suction pipe 14 through the movable component, the motor 19 can be started by the PLC to drive the rotation of the threaded rod 18 when the position of the bottom of the suction pipe 14 needs to be adjusted. The rotation of the threaded rod 18 drives the movement of the connecting plate 17, which in turn drives the movement of the connecting rod 16. The movement of the connecting rod 16 drives the movement of the fixing plate 15, which in turn drives the movement of the suction pipe 14. This changes the position of the bottom of the suction pipe 14 inside the second liquid storage chamber 12, thereby allowing the suction of wastewater at different depths. This avoids the problem of large particles and suspended solids in the wastewater settling at different depths due to different batches of wastewater or different settling times. By adjusting the suction depth of the suction pipe 14, it is possible to avoid suctioning impurities in the wastewater, which helps to improve the clarity of the wastewater, reduce the risk of clogging the evaporator, and improve the treatment effect.

[0059] Example 2

[0060] like Figures 1 to 9 As shown, the cleaning assembly includes a scraper 27 disposed inside the second liquid storage chamber 12. A rotating plate 26 is fixedly installed at the bottom end of the scraper 27. A first gear 25 is meshed inside the rotating plate 26. A first connecting shaft 24 is fixedly installed at the bottom end of the first gear 25. A second bevel gear 23 is fixedly connected at the bottom end of the first connecting shaft 24. A first bevel gear 22 is meshed at the bottom end of the second bevel gear 23. A rotating shaft 21 is fixedly installed on one side of the first bevel gear 22. A power plate 20 is installed on the outer wall of the rotating shaft 21. The power plate 20 is disposed inside the first liquid outlet pipe 5.

[0061] By configuring the cleaning components, when discharging wastewater containing large particles and suspended solids from the second storage chamber 12, the rotation of the power plate 20 drives the rotation of the rotating shaft 21, which in turn drives the rotation of the first bevel gear 22, which in turn drives the rotation of the second bevel gear 23. Salts in the water may precipitate out and adhere to the surface of the equipment, forming a scale wall that rotates, thus assisting in the discharge of wastewater from the bottom.

[0062] like Figures 1 to 9 As shown, the scraper 27 slides against the inner wall of the second liquid storage chamber 12.

[0063] Not only can it assist in the discharge of wastewater containing large particles and suspended solids inside the second liquid storage chamber 12, but it can also scrape the inner wall of the evaporator 3 during the rotation process to prevent salts in the water from precipitating out and adhering to the equipment surface, forming scale. The scale layer can be removed by the rotation of the scraper 27, making it easier to keep the inside of the second liquid storage chamber 12 clean.

[0064] like Figures 1 to 9 As shown, the rotating plate 26 is rotatably mounted on the inner wall of the first liquid outlet pipe 5, and a sealing gasket is installed between the rotating plate 26 and the first liquid outlet pipe 5.

[0065] The material used to seal between the rotating plate 26 and the first outlet pipe 5 is usually made of soft materials, such as rubber, silicone, or metal. Its function is to prevent wastewater leakage inside the evaporator 3, and also to reduce noise and vibration.

[0066] like Figures 1 to 9 As shown, a second gear 28 is meshed with the outer wall of the rotating plate 26. A locking block 34 is slidably installed inside the second gear 28. The locking block 34 is fixedly installed on the outer wall of the second connecting shaft 29. A motor 30 is fixedly installed at the bottom end of the second connecting shaft 29. The motor 30 is installed inside the fixed seat 31. The fixed seat 31 is fixedly installed at the bottom end of the evaporator 3.

[0067] When it is necessary to clean the inside of the second liquid storage chamber 12, the motor 30 can be started by controlling the PLC. The start of the motor 30 drives the rotation of the second connecting shaft 29, the rotation of the second connecting shaft 29 drives the rotation of the second gear 28, the rotation of the second gear 28 drives the rotation of the rotating plate 26, the rotation of the rotating plate 26 drives the rotation of the first gear 25, and the rotation of the first gear 25 drives the rotation of the rotating plate 26, so that the rotating plate 26 cleans the inner wall of the evaporator 3.

[0068] like Figures 1 to 9 As shown, a third connecting shaft 35 is fixedly installed at the bottom end of the second gear 28. The third connecting shaft 35 is slidably installed on the outer wall of the second connecting shaft 29. A movable plate 32 is rotatably installed on the outer wall of the third connecting shaft 35. The movable plate 32 is slidably installed inside the fixed base 31.

[0069] The outer wall of the rotating plate 26 meshes with the second gear 28, so that the scraper 27 can not only rotate when draining liquid, but also be controlled by the PLC to rotate for cleaning, thus improving its practicality.

[0070] like Figures 1 to 9 As shown, a magnetic block 33 is provided at the top of the movable plate 32, and the magnetic block 33 is fixedly installed at the bottom of the evaporator 3.

[0071] The moving plate 32 can be attracted by the magnetic block 33, so that the locking block 34 can be engaged with the inner wall of the second gear 28, ensuring the stability of the second gear 28 during rotation.

[0072] When the evaporator 3 is draining, the moving plate 32 is moved downward to separate from the magnetic block 33. The movement of the moving plate 32 drives the movement of the third connecting shaft 35. The movement of the third connecting shaft 35 drives the movement of the second gear 28, causing the second gear 28 to separate from the rotating plate 26. Then the moving plate 32 is rotated to one side to make the moving plate 32 and the magnetic block 33 misaligned, ensuring the stability of the equipment during subsequent draining.

[0073] A method for operating a nylon ATY oil-based wastewater cooling and purification device includes the following steps:

[0074] S1: First, a certain amount of wastewater is discharged into the second storage chamber 12 through the inlet pipe 4. During discharge, the amount of wastewater discharged can be observed through the observation window 9.

[0075] S2: Then the wastewater in the second storage chamber 12 is allowed to settle and the settling effect can be observed through the observation window 9.

[0076] S3: Then, based on the sedimentation effect of the wastewater, select whether to adjust the position of the bottom end of the suction pipe 14. When adjustment is required, the motor 19 can be started by controlling the PLC to drive the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the connecting plate 17 to move. The movement of the connecting plate 17 drives the connecting rod 16 to move. The movement of the connecting rod 16 drives the fixed plate 15 to move. The movement of the fixed plate 15 drives the suction pipe 14 to move, changing the position of the suction pipe 14 inside the second liquid storage chamber 12.

[0077] S4: Then, by starting the suction pump 13, the wastewater that has settled in the second storage chamber 12 is sucked into the first storage chamber 11.

[0078] S5: Then, the wastewater containing impurities in the second storage chamber 12 is discharged through the connecting pipe 6 by the control of the solenoid valve. During the discharge process, the wastewater drives the rotation of the power plate 20, the rotation of the power plate 20 drives the rotation of the rotating shaft 21, the rotation of the rotating shaft 21 drives the rotation of the first bevel gear 22, and the rotation of the first bevel gear 22 drives the rotation of the second bevel gear 23. Salts in the water may precipitate and adhere to the surface of the equipment, forming a scale wall that rotates to assist the discharge of wastewater at the bottom.

[0079] S6: After the wastewater is discharged, a new batch of wastewater can be discharged into the second storage chamber 12 through the inlet pipe 4 for sedimentation, which is convenient for subsequent use;

[0080] S7: Finally, the wastewater is evaporated at low temperature through the evaporator 3. The steam is discharged into the cooling tank 7 through the connecting pipe 6 and condensed. The condensed liquid is discharged from the second liquid outlet pipe 8.

[0081] Working principle and usage process:

[0082] When it is necessary to cool and purify the wastewater from nylon ATY oil, a certain amount of wastewater is first discharged into the second storage chamber 12 through the inlet pipe 4. During discharge, the amount of wastewater discharged can be observed through the observation window 9.

[0083] Then the wastewater in the second storage chamber 12 is allowed to settle and the settling effect can be observed through the observation window 9.

[0084] Then, based on the sedimentation effect of the wastewater, it is decided whether to adjust the position of the bottom end of the suction pipe 14. When adjustment is required, the motor 19 can be started by controlling the PLC, which drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the connecting plate 17 to move. The movement of the connecting plate 17 drives the connecting rod 16 to move. The movement of the connecting rod 16 drives the fixed plate 15 to move. The movement of the fixed plate 15 drives the suction pipe 14 to move, thus changing the position of the suction pipe 14 inside the second liquid storage chamber 12.

[0085] Then, by starting the suction pump 13, the wastewater that has settled in the second storage chamber 12 is drawn into the first storage chamber 11.

[0086] Then, the wastewater containing impurities that has settled inside the second storage chamber 12 is discharged through the connecting pipe 6 by the control of the solenoid valve. During the discharge process, the wastewater drives the rotation of the power plate 20, which in turn drives the rotation of the rotating shaft 21. The rotation of the rotating shaft 21 drives the rotation of the first bevel gear 22, which in turn drives the rotation of the second bevel gear 23. Salts in the water may precipitate out and adhere to the surface of the equipment, forming a scale wall that rotates to assist the discharge of wastewater at the bottom.

[0087] After the wastewater is discharged, a new batch of wastewater can be discharged into the second storage chamber 12 through the inlet pipe 4 for sedimentation, which is convenient for subsequent use.

[0088] Finally, the wastewater is evaporated at low temperature in evaporator 3, and the steam is discharged into cooling tank 7 through connecting pipe 6 for condensation. The condensed liquid is discharged from the second liquid outlet pipe 8.

[0089] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.

2. The working method of the nylon ATY oil wastewater cooling and purification device according to claim 1, characterized in that, Includes the following steps: S1: First, a certain amount of wastewater is discharged into the second storage chamber (12) through the inlet pipe (4). During discharge, the amount of wastewater discharged is observed through the observation window (9). S2: Then, the wastewater in the second storage chamber (12) is allowed to settle and the settling effect of the wastewater is observed through the observation window (9); S3: Then, based on the sedimentation effect of the wastewater, choose whether to adjust the position of the bottom of the suction pipe (14). When adjustment is required, start the motor (19) through PLC control, drive the threaded rod (18) to rotate, drive the connecting plate (17) to move, drive the connecting rod (16) to move, drive the fixed plate (15) to move, drive the suction pipe (14) to move, and change the position of the suction pipe (14) inside the second liquid storage chamber (12). S4: Then, by starting the suction pump (13), the wastewater that has settled in the second storage chamber (12) is sucked into the first storage chamber (11); S5: Then, the wastewater containing impurities in the second storage chamber (12) is discharged through the connecting pipe (6) by the control of the solenoid valve. During the discharge process, the wastewater drives the rotation of the power plate (20). The rotation of the power plate (20) drives the rotation of the rotating shaft (21). The rotation of the rotating shaft (21) drives the rotation of the first bevel gear (22). The rotation of the first bevel gear (22) drives the rotation of the second bevel gear (23). The top of the second bevel gear (23) is fixedly connected to the first connecting shaft (24). The top of the first connecting shaft (24) is fixedly installed with the first gear (25). The second bevel gear (23) drives the first gear (25) to rotate through the first connecting shaft (24). The first gear (25) drives the rotating plate (26) to rotate through meshing connection, thereby driving the scraper (27) to rotate. The scraper (27) slides and fits against the inner wall of the second liquid storage chamber (12). It not only assists in the discharge of wastewater containing large particles and suspended matter inside the second liquid storage chamber (12), but also scrapes the inner wall of the evaporator (3) during the rotation process to prevent salts in the water from precipitating and adhering to the surface of the equipment, forming scale, and keeping the inside of the second liquid storage chamber (12) clean. S6: After the wastewater is discharged, a new batch of wastewater is discharged into the second storage chamber (12) through the inlet pipe (4) for sedimentation, which is convenient for subsequent use; S7: Finally, the wastewater is evaporated at low temperature through the evaporator (3), and the steam is discharged into the cooling tank (7) through the connecting pipe (6) for condensation. The condensed liquid is discharged from the second liquid outlet pipe (8).
