Description

Technical Field

[0001] The present invention belongs to the field related to wastewater treatment technology, and more specifically, to a wastewater treatment device for water-based ink wastewater. Background Art

[0002] Water-based ink wastewater mainly comes from ink preparation, printer cleaning, and ink residue during the printing process. These wastewaters contain a large amount of chemical substances such as pigments, resins, solvents, and additives. This water-based ink wastewater treatment device utilizes thermal cycle technology to complete the separation operation between ink and water through evaporation.

[0003] The patent document with the publication number CN118908381A records a wastewater treatment device for water-based ink production, which relates to the field of preliminary impurity removal technology in the purification process of wastewater generated during water-based ink production. A valve for discharging liquid is installed inside the drain pipe, and a flange is fixedly connected to the front end of the drain pipe. A transmission is fixedly connected to the left side of the treatment component, solving the problem that in the preliminary treatment of existing wastewater treatment devices, generally, sedimentation and filtration methods are mostly relied on to treat wastewater, but it not only takes a long time during filtration and sedimentation, but also affects the treatment efficiency of sewage because the filter screen needs to be frequently cleaned. By using the settings of the generator, controller, and adsorption component, when in use, the generator can generate static electricity for the controller to quickly remove impurities in the pretreatment component.

[0004] The above device has certain deficiencies during the operation of treating water-based ink wastewater. The above device uses physical filtration and sedimentation methods to treat water-based ink wastewater, while water-based ink wastewater is different from general wastewater. Water-based ink wastewater contains a large amount of organic substances such as pigments and resins. These organic substances form colloids or dissolved states in the wastewater and are difficult to remove by conventional filtration methods. Secondly, water-based ink wastewater has different colors. When the treatment device needs to treat water-based ink wastewater of another color, there will be residual ink in the tank structure, which affects the subsequent treatment of water-based ink wastewater and does not have an auxiliary cleaning structure. Summary of the Invention

[0005] The purpose of the present invention is to provide a water-based ink wastewater treatment device, which can solve the existing problems.

[0006] The problems solved by the present invention are:

[0007] 1. The above device uses physical filtration and sedimentation methods to treat water-based ink wastewater, while water-based ink wastewater is different from general wastewater. Water-based ink wastewater contains a large amount of organic substances such as pigments and resins. These organic substances form colloids or dissolved states in the wastewater and are difficult to remove by conventional filtration methods;

[0008] 2. Secondly, the aqueous ink wastewater has different colors. When the treatment equipment needs to process the aqueous ink wastewater of another color, there will be some residual ink in the tank structure, which will affect the subsequent treatment of the aqueous ink wastewater and there is no auxiliary cleaning structure.

[0009] The object of the present invention can be achieved by the following technical solutions:

[0010] An aqueous ink wastewater treatment device, including a cabinet shell, a distillation kettle and a condenser. The distillation kettle and the condenser are both fixedly installed inside the cabinet shell. The upper end of the distillation kettle is connected to the condenser through a pipeline. One side of the distillation kettle is provided with a liquid inlet pipe for transporting the aqueous ink wastewater. A first evaporator is fixedly installed inside the distillation kettle. A second evaporator is fixedly installed inside the condenser. A compressor for cooperating with the first evaporator is fixedly installed inside the cabinet shell, and a condensing fan for cooperating with the first evaporator is arranged above the compressor. The compressor, the first evaporator, the condensing fan and the second evaporator are all connected through. A flushing ring is movably installed inside the distillation kettle, and the flushing ring is movably sleeved outside the first evaporator.

[0011] As a further technical solution of the present invention, a drain pipe is installed through the lower part of the distillation kettle, and a drain pump is arranged at the output end of the drain pipe. A water purification pipe is fixedly installed at the output end of the condenser. The aqueous ink wastewater is introduced into the distillation kettle through the liquid inlet pipe. The refrigerant is compressed by the compressor. After being compressed into a high-temperature and high-pressure gas state, it enters the first evaporator. The first evaporator is used to heat the aqueous ink wastewater in the distillation kettle, so that the water body evaporates to form water vapor. The water vapor is discharged into the condenser through the pipeline. When the water body of the aqueous ink wastewater has completely evaporated, the remaining liquid is ink, and the ink is discharged outwards through the cooperation of the drain pump and the drain pipe.

[0012] As a further technical solution of the present invention, a vacuum generator and a centrifugal pump are arranged at one end of the water purification pipe. The vacuum generator is installed on one side of the centrifugal pump, and the vacuum generator and the centrifugal pump are connected through a pipe body. The refrigerant after releasing heat in the first evaporator is transported to the condensing fan. The condensing fan is used to cool down the refrigerant. Finally, it becomes a liquid refrigerant and then enters the second evaporator through an expansion valve for evaporation and heat absorption, so as to perform heat absorption treatment on the water vapor in the condenser, so that the water vapor becomes a liquid and is discharged through the water purification pipe in cooperation with the vacuum generator and the centrifugal pump.

[0013] As a further technical solution of the present invention, a water tank is provided on one side of the centrifugal pump. The centrifugal pump and the water tank are fixed through a pipe body. The first evaporator is located at the middle position of the distillation kettle, and the bottom of the first evaporator and the distillation kettle are butt-jointed and fixed through a fixing seat. The purified water discharged by the centrifugal pump is stored in the water tank, and the fixing seat fixes the first evaporator from the bottom, so that there is no contact between the periphery of the first evaporator and the distillation kettle, allowing the washing ring to move up and down through the first evaporator.

[0014] As a further technical solution of the present invention, the washing ring and the distillation kettle are movably connected through a lifting guide rod, and the washing ring and the distillation kettle are driven by a lifting screw rod. The lifting screw rod is located on one side of the lifting guide rod. The user drives the lifting screw rod to rotate through a motor, so that the lifting screw rod drives the washing ring to move up and down by using a thread structure, enabling the washing ring to pass through the first evaporator, thereby washing the surface of the first evaporator by using a nozzle.

[0015] As a further technical solution of the present invention, several groups of lifting sleeves for cooperating with the lifting screw rod and the lifting guide rod are arranged inside the washing ring. The several groups of lifting sleeves are annularly distributed. One group of lifting sleeves is of a thread structure, and the rest of the lifting sleeves are of a roller structure. The lifting sleeve of the thread structure cooperates with the lifting screw rod, and the lifting sleeves of the roller structure cooperate with the lifting guide rod, enabling the washing ring to move vertically.

[0016] As a further technical solution of the present invention, an annular pipe is fixedly installed inside the washing ring. Several groups of nozzles are fixedly installed on both the inner surface and the outer surface of the washing ring. The annular pipe and the nozzles are connected in a through manner. By using the nozzles arranged inside and outside, when the washing ring moves up and down, the inner wall of the distillation kettle and the outer surface of the first evaporator can be synchronously washed, and the annular pipe can supply water to the nozzles.

[0017] As a further technical solution of the present invention, a washer is provided on one side of the distillation kettle. A hose is provided between the washer and the distillation kettle. A cleaning tank is fixedly installed inside the washer. During the cleaning operation, one end of the hose is passed through the notch of the distillation kettle, and one end of the hose is butt-jointed and fixed with the washing ring, and the cleaning tank provides cleaning liquid for the washing ring through the hose.

[0018] As a further technical solution of the present invention, a pump is fixedly installed at the lower part of the cleaning tank. A water inlet pipe is installed at one end of the pump. Both the cleaning tank and the water inlet pipe are controlled by valves. When the cleaning tank is opened, the pump can be used for the conveying operation of the cleaning liquid. When the water inlet pipe is opened, the pump can be used for the conveying operation of clean water, which is convenient for flushing the inside of the distillation kettle with clean water.

[0019] As a further technical solution of the present invention, several groups of flushing rings are annularly distributed. A connector for cooperating with a flexible hose is provided on the outer side of the annular pipe, and a motor for cooperating with a lifting screw rod is provided at the upper end of the distillation kettle.

[0020] Advantages of the present invention:

[0021] 1. By providing a distillation kettle and a condenser, when the water-based ink wastewater treatment equipment is used, it can utilize the temperature change of the refrigerant to complete the evaporation and cooling treatment of the water-based ink wastewater, so that the ink and the water body are evaporated and separated, preventing the discharge of water-based ink wastewater from the source, enabling the reuse of printing wastewater, and the treated ink can be used again, avoiding water pollution incidents.

[0022] During operation, the water-based ink wastewater is introduced into the distillation kettle through the liquid inlet pipe. The refrigerant is compressed by a compressor and enters the first evaporator after being compressed into a high-temperature and high-pressure gas state. The first evaporator is used to heat the water-based ink wastewater in the distillation kettle, causing the water body to evaporate into water vapor. The water vapor is discharged into the condenser through a pipeline. When the water body of the water-based ink wastewater is completely evaporated, the remaining liquid is the ink, which is discharged outward through a drain pump and a drain pipe. The refrigerant that has released heat after passing through the first evaporator is transported to a condensing fan, and the condensing fan is used to cool down the refrigerant, which finally becomes a liquid refrigerant and then enters the second evaporator through an expansion valve for evaporation and heat absorption, thereby performing heat absorption treatment on the water vapor in the condenser, causing the water vapor to cool down to form distilled water, which is discharged through a water purification pipe in cooperation with a vacuum generator and a centrifugal pump. The purified water discharged through the centrifugal pump is stored in a water tank. This equipment uses a thermal cycle technology for evaporation treatment, and the treated ink can be used again after adding color paste.

[0023] 2. By providing flushing rings and a washer, when the water-based ink wastewater treatment equipment is used, it has a two-way flushing structure, which can respectively complete the flushing operations of the inside of the first evaporator and the inner wall of the distillation kettle, facilitating the separation treatment of water-based ink wastewater of different colors.

[0024] When in use, the fixing seat fixes the first evaporator from the bottom so that the four sides of the first evaporator are not in contact with the distillation kettle, allowing the flushing ring to move up and down through the first evaporator, and passing one end of the hose through the slot of the distillation kettle so that one end of the hose is docked and fixed with the flushing ring. The cleaning tank is used to provide cleaning liquid to the flushing ring through the hose. The user drives the lifting screw to rotate through the motor so that the lifting screw drives the flushing ring to move up and down using the threaded structure, so that the flushing ring passes through the first evaporator. Using the nozzles arranged inside and outside, the inner wall of the distillation kettle and the outer surface of the first evaporator can be synchronously flushed when the flushing ring moves up and down. The nozzle can be supplied with water through the annular tube. When the cleaning tank is opened, the pump can be used to transport the cleaning liquid. When the water inlet pipe is opened, the pump can be used to transport clean water, which is convenient for flushing the inside of the distillation kettle with clean water, thereby quickly completing the equipment cleaning operation.

[0033] As Figure 1 shown, the aqueous ink wastewater treatment equipment includes a cabinet shell 1, a distillation kettle 2 and a condenser 3. The distillation kettle 2 and the condenser 3 are both fixedly installed inside the cabinet shell 1. The upper end of the distillation kettle 2 is connected to the condenser 3 through a pipeline. A liquid inlet pipe 13 for conveying aqueous ink wastewater is provided on one side of the distillation kettle 2. A first evaporator 14 is fixedly installed inside the distillation kettle 2. A second evaporator 12 is fixedly installed inside the condenser 3. A compressor 5 for cooperating with the first evaporator 14 is fixedly installed inside the cabinet shell 1. And a condensing fan 4 for cooperating with the first evaporator 14 is arranged above the compressor 5. The compressor 5, the first evaporator 14, the condensing fan 4 and the second evaporator 12 are all connected through. A flushing ring 20 is movably installed inside the distillation kettle 2. The flushing ring 20 is movably sleeved outside the first evaporator 14.

[0034] To solve the separation problem of aqueous ink wastewater, as Figure 2 shown, a drain pipe 7 is installed through the lower part of the distillation kettle 2. A drain pump 6 is arranged at the output end of the drain pipe 7. A water purification pipe 11 is fixedly installed at the output end of the condenser 3. The aqueous ink wastewater is introduced into the distillation kettle 2 through the liquid inlet pipe 13. The refrigerant is compressed by the compressor 5. After being compressed into a high-temperature and high-pressure gas state, the refrigerant enters the first evaporator 14. The first evaporator 14 is used to heat the aqueous ink wastewater in the distillation kettle 2, so that the water body evaporates to form water vapor. The water vapor is discharged into the condenser 3 through the pipeline. When the water body of the aqueous ink wastewater has completely evaporated, the remaining liquid is ink. The ink is discharged outward through the drain pump 6 cooperating with the drain pipe 7.

[0035] As Figure 2 shown, a vacuum generator 10 and a centrifugal pump 9 are arranged at one end of the water purification pipe 11. The vacuum generator 10 is installed on one side of the centrifugal pump 9. And the vacuum generator 10 and the centrifugal pump 9 are connected through a pipe body. The refrigerant after releasing heat in the first evaporator 14 is conveyed to the condensing fan 4. The condensing fan 4 is used to cool down the refrigerant. Finally, it becomes a liquid refrigerant and then enters the second evaporator 12 through an expansion valve for evaporation and heat absorption, so as to perform heat absorption treatment on the water vapor in the condenser 3, so that the water vapor becomes liquid and is discharged through the water purification pipe 11 in cooperation with the vacuum generator 10 and the centrifugal pump 9.

[0036] As Figure 2As shown in the figure, a water tank 8 is provided on one side of the centrifugal pump 9. The centrifugal pump 9 and the water tank 8 are fixed through a pipe body. The first evaporator 14 is located at the middle position of the distillation kettle 2, and the bottom of the first evaporator 14 and the distillation kettle 2 are butt-jointed and fixed through a fixing seat 17. The purified water discharged from the centrifugal pump 9 is stored in the water tank 8, and the fixing seat 17 fixes the first evaporator 14 from the bottom, so that there is no contact between the periphery of the first evaporator 14 and the distillation kettle 2, allowing the flushing ring 20 to move up and down through the first evaporator 14.

[0037] To solve the cleaning problem of the equipment itself, such as Figure 3 As shown in the figure, the flushing ring 20 and the distillation kettle 2 are movably connected through a lifting guide rod 18, and the flushing ring 20 and the distillation kettle 2 are driven by a lifting screw rod 19. The lifting screw rod 19 is located on one side of the lifting guide rod 18. The user drives the lifting screw rod 19 to rotate through a motor, so that the lifting screw rod 19 drives the flushing ring 20 to move up and down by using a threaded structure, enabling the flushing ring 20 to pass through the first evaporator 14, thereby flushing the surface of the first evaporator 14 by using the nozzle 24.

[0038] Such as Figure 3 As shown in the figure, several groups of lifting sleeves 26 for cooperating with the lifting screw rod 19 and the lifting guide rod 18 are arranged inside the flushing ring 20. The several groups of lifting sleeves 26 are annularly distributed. One group of lifting sleeves 26 is of a threaded structure, and the rest of the lifting sleeves 26 are of a roller structure. The threaded lifting sleeve 26 cooperates with the lifting screw rod 19, and the roller-structured lifting sleeve 26 cooperates with the lifting guide rod 18, enabling the flushing ring 20 to move vertically.

[0039] Such as Figure 4 As shown in the figure, an annular pipe 25 is fixedly installed inside the flushing ring 20. A number of groups of nozzles 24 are fixedly installed on both the inner surface and the outer surface of the flushing ring 20. The annular pipe 25 and the nozzles 24 are connected in a through manner. By using the nozzles 24 arranged inside and outside, when the flushing ring 20 moves up and down, the inner wall of the distillation kettle 2 and the outer surface of the first evaporator 14 can be synchronously flushed. The annular pipe 25 can supply water to the nozzles 24.

[0040] Such as Figure 4 As shown in the figure, a cleaner 21 is provided on one side of the distillation kettle 2. A hose 15 is arranged between the cleaner 21 and the distillation kettle 2. A cleaning tank 23 is fixedly installed inside the cleaner 21. During the cleaning operation, one end of the hose 15 is passed through the notch of the distillation kettle 2, so that one end of the hose 15 is butt-jointed and fixed with the flushing ring 20, and the cleaning tank 23 provides cleaning liquid for the flushing ring 20 through the hose 15.

[0041] Such as Figure 5As shown in the figure, a pump 16 is fixedly installed at the lower part of the cleaning tank 23. One end of the pump 16 is equipped with a water inlet pipe 22. Both the cleaning tank 23 and the water inlet pipe 22 are controlled by valves. When the cleaning tank 23 is opened, the pump 16 can be used to transport the cleaning liquid. When the water inlet pipe 22 is opened, the pump 16 can be used to transport clean water, which is convenient for flushing the inside of the distillation kettle 2 with clean water.

[0042] Several groups of flushing rings 20 are all annularly distributed. A joint for cooperating with the flexible hose 15 is provided on the outer side of the annular pipe 25. An electric motor for cooperating with the lifting lead screw 19 is provided at the upper end of the distillation kettle 2.

[0043] In use, traditional equipment uses physical filtration and precipitation methods to treat water-based ink wastewater. However, water-based ink wastewater is different from general wastewater. Water-based ink wastewater contains a large amount of organic substances, such as pigments, resins, etc. These organic substances form colloids or dissolved states in the wastewater and are difficult to remove by conventional filtration methods.

[0044] By setting the distillation kettle 2 and the condenser 3, when this water-based ink wastewater treatment equipment is in use, it can utilize the heat and cold changes of the refrigerant to complete the evaporation and cooling treatment of the water-based ink wastewater, enabling the ink and the water body to evaporate and separate, eliminating the discharge of water-based ink wastewater from the source, making the printing wastewater reusable, and the treated ink can be used again, avoiding water pollution incidents.

[0045] During operation, the water-based ink wastewater is introduced into the distillation kettle 2 through the liquid inlet pipe 13. The refrigerant is compressed by the compressor 5. After being compressed into a high-temperature and high-pressure gas state, the refrigerant enters the first evaporator 14. The first evaporator 14 is used to heat the water-based ink wastewater in the distillation kettle 2, causing the water body to evaporate into water vapor. The water vapor is discharged into the condenser 3 through a pipeline. When the water body of the water-based ink wastewater has completely evaporated, the remaining liquid is the ink. The ink is discharged outward through the drain pump 6 and the drain pipe 7. The refrigerant that has released heat after passing through the first evaporator 14 is transported to the condensing fan 4. The condensing fan 4 is used to cool down the refrigerant, and finally it becomes a liquid refrigerant. Then it enters the second evaporator 12 through the expansion valve for evaporation and heat absorption, thereby absorbing the heat of the water vapor in the condenser 3, causing the water vapor to cool and form distilled water, which is discharged through the water purification pipe 11 in cooperation with the vacuum generator 10 and the centrifugal pump 9. The purified water discharged through the centrifugal pump 9 is stored in the water tank 8. This equipment uses a thermal cycle technology for evaporation treatment, and the treated ink can be used again after adding color paste.

[0046] Water-based ink wastewater has different colors. When the treatment equipment needs to treat water-based ink wastewater of another color, there will be some residual ink in its tank structure, which will affect the subsequent treatment of water-based ink wastewater and does not have an auxiliary cleaning structure.

[0047] Therefore, by setting the flushing ring 20 and the washer 21, when the water-based ink wastewater treatment equipment is in use, it has a two-way flushing structure, which can respectively complete the flushing operations of the inside of the first evaporator 14 and the inner wall of the distillation kettle 2, facilitating the separation treatment of water-based ink wastewater of different colors;

[0048] During use, the fixing seat 17 fixes the first evaporator 14 from the bottom, so that there is no contact between the periphery of the first evaporator 14 and the distillation kettle 2, allowing the flushing ring 20 to move up and down through the first evaporator 14. One end of the hose 15 is passed through the notch of the distillation kettle 2, so that one end of the hose 15 is fixedly docked with the flushing ring 20. The cleaning liquid is provided to the flushing ring 20 by the cleaning tank 23 through the hose 15. The user drives the lifting screw rod 19 to rotate by the motor, so that the lifting screw rod 19 drives the flushing ring 20 to move up and down by using the thread structure, enabling the flushing ring 20 to pass through the first evaporator 14. By using the spray heads 24 arranged inside and outside, when the flushing ring 20 moves up and down, the inner wall of the distillation kettle 2 and the outer surface of the first evaporator 14 can be synchronously flushed. The annular pipe 25 can supply water to the spray heads 24. When the cleaning tank 23 is opened, the pump 16 can be used for the conveying operation of the cleaning liquid. When the water inlet pipe 22 is opened, the pump 16 can be used for the conveying operation of clean water, facilitating the clean water flushing of the inside of the distillation kettle 2, thereby quickly completing the equipment cleaning operation.

[0049] The above are only the preferred embodiments of the present invention, and do not impose any form of limitation on the present invention. Although the present invention has been disclosed above with the preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to obtain equivalent embodiments with equivalent changes, but as long as the technical content of the present invention is not departed from, any brief modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the present invention still fall within the scope of the technical solution of the present invention.
