Description

Technical Field

[0001] This utility model belongs to the field of wastewater treatment technology, and more specifically, it relates to water-based ink wastewater treatment equipment. Background Technology

[0002] Water-based ink wastewater mainly originates from ink mixing, printing press cleaning, and ink residue during the printing process. This wastewater contains a large amount of chemical substances such as pigments, resins, solvents, and additives. This water-based ink wastewater treatment equipment utilizes thermal circulation technology to separate ink and water through evaporation.

[0003] Patent document CN118908381A describes a wastewater treatment device for water-based ink production, relating to the field of preliminary impurity removal technology in the purification of wastewater generated during the production of water-based inks. The device features a drain pipe with an internal valve for draining, and a flange fixedly connected to the front end of the drain pipe. A gearbox is fixedly connected to the left side of the treatment component. This addresses the problem that existing wastewater treatment equipment typically relies on sedimentation and filtration for preliminary treatment, which is time-consuming and requires frequent cleaning of the filter screen, thus affecting wastewater treatment efficiency. By utilizing a generator, controller, and adsorption component, the device allows for rapid removal of impurities from the pretreatment component through electrostatic generation by the generator.

[0004] The aforementioned equipment has certain shortcomings in treating water-based ink wastewater. While it employs physical filtration and sedimentation, water-based ink wastewater differs from general wastewater. It contains a large amount of organic matter, such as pigments and resins, which form colloids or dissolve in the wastewater, making them difficult to remove using conventional filtration methods. Furthermore, water-based ink wastewater comes in various colors. When the equipment needs to treat a different color of water-based ink wastewater, some ink residue may remain inside the tank, affecting subsequent treatment. It also lacks an auxiliary cleaning structure. Utility Model Content

[0005] The purpose of this invention is to provide a water-based ink wastewater treatment device that can solve existing problems.

[0006] The problem solved by this utility model is:

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

[0008] 2. Secondly, water-based ink wastewater comes in different colors. When the treatment equipment needs to treat water-based ink wastewater of another color, some ink will remain in the tank structure, which will affect the subsequent treatment of water-based ink wastewater. It does not have an auxiliary cleaning structure.

[0009] The objective of this utility model can be achieved through the following technical solutions:

[0010] A water-based ink wastewater treatment device includes 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 and the condenser are connected by a pipe. An inlet pipe for conveying water-based ink wastewater is provided on one side of the distillation kettle. A first evaporator is fixedly installed inside the distillation kettle, and a second evaporator is fixedly installed inside the condenser. A compressor for use with the first evaporator is fixedly installed inside the cabinet shell, and a condensing fan for use with the first evaporator is provided above the compressor. The compressor, the first evaporator, the condensing fan, and the second evaporator are all connected in a continuous manner. A flushing ring is movably installed inside the distillation kettle, and the flushing ring is movably sleeved on the outside of the first evaporator.

[0011] As a further technical solution of this utility model, a drain pipe is installed through the lower part of the distillation kettle, and a drain pump is provided at the output end of the drain pipe. A clean water pipe is fixedly installed at the output end of the condenser. Water-based ink wastewater is introduced into the distillation kettle through the inlet pipe. The refrigerant is compressed by the compressor and then enters the first evaporator after being compressed into a high-temperature and high-pressure gaseous state. The first evaporator heats the water-based ink wastewater in the distillation kettle, so that the water evaporates and forms water vapor. The water vapor is discharged into the condenser through the pipe. When the water-based ink wastewater has completely evaporated, the remaining liquid is ink, which is discharged out through the drain pump and the drain pipe.

[0012] As a further technical solution of this utility model, a vacuum generator and a centrifugal pump are provided 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 by a pipe body. The refrigerant after releasing heat in the first evaporator is transported to the condenser fan. The condenser fan is used to cool the refrigerant and finally turn it into liquid refrigerant. Then, it enters the second evaporator through the expansion valve to evaporate and absorb heat, thereby absorbing heat from the water vapor in the condenser, so that the water vapor is liquid and discharged from the water purification pipe in conjunction with the vacuum generator and the centrifugal pump.

[0013] As a further technical solution of this utility model, a water tank is provided on one side of the centrifugal pump, and the centrifugal pump and the water tank are fixed together by a pipe. The first evaporator is located in the middle of the distillation vessel, and the bottom of the first evaporator and the distillation vessel are fixed together by a fixing seat. The clean 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 the periphery of the first evaporator does not contact the distillation vessel, allowing the rinsing ring to move up and down through the first evaporator.

[0014] As a further technical solution of this utility model, the rinsing ring and the distillation vessel are movably connected by a lifting guide rod, and the rinsing ring and the distillation vessel are driven by a lifting screw. The lifting screw is located on one side of the lifting guide rod. The user drives the lifting screw to rotate by a motor, so that the lifting screw drives the rinsing ring to move up and down by means of a threaded structure, so that the rinsing ring passes through the first evaporator, thereby using a nozzle to rinse the surface of the first evaporator.

[0015] As a further technical solution of this utility model, the inner side of the flushing ring is provided with several sets of lifting sleeves that cooperate with the lifting screw and the lifting guide rod. The sets of lifting sleeves are arranged in a ring. One set of lifting sleeves is threaded, and the rest of the lifting sleeves are rollers. The threaded lifting sleeves are used in conjunction with the lifting screw, while the roller lifting sleeves are used in conjunction with the lifting guide rod, so that the flushing ring can move vertically.

[0016] As a further technical solution of this utility model, an annular tube is fixedly installed inside the rinsing ring, and several sets of nozzles are fixedly installed on the inner and outer surfaces of the rinsing ring. The annular tube and the nozzles are connected in a continuous manner. By using the nozzles set inside and outside, the inner wall of the distillation vessel and the outer surface of the first evaporator can be rinsed simultaneously when the rinsing ring moves up and down. Water can be supplied to the nozzles through the annular tube.

[0017] As a further technical solution of this utility model, a cleaner is provided on one side of the distillation vessel, and a hose is provided between the cleaner and the distillation vessel. A cleaning tank is fixedly installed inside the cleaner. During the cleaning operation, one end of the hose is passed through the groove of the distillation vessel so that one end of the hose is connected and fixed with the rinsing ring. The cleaning tank provides cleaning fluid to the rinsing ring through the hose.

[0018] As a further technical solution of this utility model, a pump is fixedly installed at the lower part of the cleaning tank, and a water inlet pipe is installed at one end of the pump. Both the cleaning tank and the water inlet pipe are controlled by a valve body. 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 facilitates the rinsing of the inside of the distillation vessel with clean water.

[0019] As a further technical solution of this utility model, several sets of rinsing rings are arranged in a ring shape, and the outer side of the ring tube is provided with a connector for use with a hose. The upper end of the distillation vessel is provided with a motor for use with a lifting screw.

[0020] The beneficial effects of this utility model are:

[0021] 1. By setting up a distillation kettle and a condenser, the water-based ink wastewater treatment equipment can utilize the temperature changes of the refrigerant to complete the evaporation and cooling treatment of the water-based ink wastewater, so that the ink and water are separated by evaporation, eliminating the discharge of water-based ink wastewater from the source, allowing printing wastewater to be reused, and the treated ink can be reused, thus avoiding water pollution incidents.

[0022] During operation, water-based ink wastewater is introduced into the distillation kettle via the inlet pipe. The refrigerant is compressed into a high-temperature, high-pressure gaseous state and then enters the first evaporator. The first evaporator heats the water-based ink wastewater in the distillation kettle, causing the water to evaporate and form water vapor. The water vapor is discharged into the condenser through a pipe. Once the water in the wastewater has completely evaporated, the remaining liquid is ink. The ink is discharged outwards via a drain pump and drain pipe. The refrigerant, after releasing heat in the first evaporator, is transported to a condenser fan. The condenser fan cools the refrigerant, reducing it to liquid. This liquid refrigerant then enters the second evaporator through an expansion valve for further evaporation and heat absorption. This process further cools the water vapor in the condenser, causing it to cool and form distilled water. This distilled water, along with a vacuum generator and centrifugal pump, is discharged through a clean water pipe. The clean water discharged by the centrifugal pump is stored in a water tank. This equipment uses thermal circulation technology for evaporation treatment, and the treated ink can be reused after adding colorant.

[0023] 2. By setting up a flushing ring and a cleaner, the water-based ink wastewater treatment equipment has a bidirectional flushing structure, which can separately complete the flushing operation of the inner wall of the first evaporator and the inner wall of the distillation kettle, making it convenient to separate and treat water-based ink wastewater of different colors.

[0024] In use, the mounting base secures the first evaporator from the bottom, ensuring that the evaporator's perimeter does not contact the distillation vessel. This allows the rinsing ring to move up and down through the first evaporator. One end of the hose is threaded through the slot of the distillation vessel, connecting and securing it to the rinsing ring. The cleaning tank supplies cleaning fluid to the rinsing ring via the hose. The user drives the lifting screw via a motor, causing it to move up and down using a threaded structure. The rinsing ring passes through the first evaporator, and the internal and external nozzles simultaneously rinse the inner wall of the distillation vessel and the outer surface of the first evaporator as the rinsing ring moves up and down. Water is supplied to the nozzles via a ring pipe. When the cleaning tank is open, a pump can be used to deliver the cleaning fluid; when the water inlet pipe is open, a pump can be used to deliver clean water, facilitating thorough rinsing of the distillation vessel's interior and quickly completing the equipment cleaning process.

[0032] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0033] like Figure 1 As shown, the water-based 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 and the condenser 3 are connected by a pipe. An inlet pipe 13 for conveying water-based 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 use with the first evaporator 14 is fixedly installed inside the cabinet shell 1. A condensing fan 4 for use with the first evaporator 14 is provided above the compressor 5. The compressor 5, the first evaporator 14, the condensing fan 4, and the second evaporator 12 are all connected in a continuous manner. A flushing ring 20 is movably installed inside the distillation kettle 2. The flushing ring 20 is movably sleeved on the outside of the first evaporator 14.

[0034] To solve the problem of separating water-based ink wastewater, such as Figure 2 As shown, a drain pipe 7 is installed through the lower part of the distillation vessel 2. A drain pump 6 is installed at the output end of the drain pipe 7. A clean water pipe 11 is fixedly installed at the output end of the condenser 3. Water-based ink wastewater is introduced into the interior of the distillation vessel 2 through the inlet pipe 13. The refrigerant is compressed by the compressor 5. After the refrigerant is compressed into a high-temperature and high-pressure gaseous state, it enters the first evaporator 14. The first evaporator 14 heats the water-based ink wastewater in the distillation vessel 2, so that the water evaporates and forms water vapor. The water vapor is discharged into the interior of the condenser 3 through the pipe. When the water-based ink wastewater has evaporated completely, the remaining liquid is ink. The ink is discharged out through the drain pump 6 and the drain pipe 7.

[0035] like Figure 2 As shown, a vacuum generator 10 and a centrifugal pump 9 are installed 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 by a pipe body. The refrigerant after releasing heat in the first evaporator 14 is transported to the condenser fan 4. The condenser fan 4 is used to cool the refrigerant and finally turn it into liquid refrigerant. Then, it enters the second evaporator 12 through the expansion valve to evaporate and absorb heat, thereby absorbing heat from the water vapor in the condenser 3, so that the water vapor is in liquid form and discharged from the water purification pipe 11 along with the vacuum generator 10 and the centrifugal pump 9.

[0036] like Figure 2As shown, 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 together by a pipe. The first evaporator 14 is located in the middle of the distillation vessel 2, and the bottom of the first evaporator 14 is fixed to the distillation vessel 2 by a fixing seat 17. The clean water discharged by 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 the first evaporator 14 does not contact the distillation vessel 2, allowing the rinsing ring 20 to move up and down through the first evaporator 14.

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

[0038] like Figure 3 As shown, the inner side of the flushing ring 20 is provided with several sets of lifting sleeves 26 that work with the lifting screw 19 and the lifting guide rod 18. The sets of lifting sleeves 26 are arranged in a ring. One set of lifting sleeves 26 has a threaded structure, while the rest of the lifting sleeves 26 have a roller structure. The threaded lifting sleeves 26 work with the lifting screw 19, while the roller lifting sleeves 26 work with the lifting guide rod 18, allowing the flushing ring 20 to move vertically.

[0039] like Figure 4 As shown, an annular pipe 25 is fixedly installed inside the flushing ring 20. Several sets of nozzles 24 are fixedly installed on the inner and outer surfaces of the flushing ring 20. The annular pipe 25 and the nozzles 24 are connected in a continuous manner. By using the nozzles 24 installed inside and outside, the inner wall of the distillation vessel 2 and the outer surface of the first evaporator 14 can be flushed simultaneously when the flushing ring 20 moves up and down. Water can be supplied to the nozzles 24 through the annular pipe 25.

[0040] like Figure 4 As shown, a cleaner 21 is provided on one side of the distillation vessel 2, and a hose 15 is provided between the cleaner 21 and the distillation vessel 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 slot of the distillation vessel 2, so that one end of the hose 15 is connected and fixed with the rinsing ring 20. The cleaning tank 23 provides cleaning fluid to the rinsing ring 20 through the hose 15.

[0041] like Figure 5As shown, a pump 16 is fixedly installed at the lower part of the cleaning tank 23. A water inlet pipe 22 is installed at one end of the pump 16. Both the cleaning tank 23 and the water inlet pipe 22 are controlled by a valve body. When the cleaning tank 23 is opened, the pump 16 can be used to transport the cleaning solution. When the water inlet pipe 22 is opened, the pump 16 can be used to transport clean water, which facilitates the rinsing of the inside of the distillation vessel 2 with clean water.

[0042] Several sets of flushing rings 20 are arranged in a ring shape. The outer side of the ring tube 25 is provided with a connector for use with the hose 15. The upper end of the distillation vessel 2 is provided with a motor for use with the lifting screw 19.

[0043] When in use, traditional equipment uses physical filtration and sedimentation to treat water-based ink wastewater. However, water-based ink wastewater is different from general wastewater. It contains a large amount of organic matter, such as pigments and resins. These organic matter form colloidal or dissolved states in the wastewater and are difficult to remove through conventional filtration methods.

[0044] By setting up a distillation vessel 2 and a condenser 3, the water-based ink wastewater treatment equipment can utilize the temperature changes of the refrigerant to complete the evaporation and cooling treatment of the water-based ink wastewater, so that the ink and water are separated by evaporation, eliminating the discharge of water-based ink wastewater from the source, allowing printing wastewater to be reused, and the treated ink can be reused, thus avoiding water pollution incidents.

[0045] During operation, water-based ink wastewater is introduced into the distillation kettle 2 via the inlet pipe 13. The refrigerant is compressed by the compressor 5 into a high-temperature, high-pressure gaseous state, which then enters the first evaporator 14. The first evaporator 14 heats the water-based ink wastewater in the distillation kettle 2, causing the water to evaporate and form water vapor. The water vapor is discharged into the condenser 3 through a pipe. After the water-based ink wastewater has completely evaporated, the remaining liquid is ink. The ink is discharged outwards via the drain pump 6 and drain pipe 7, passing through the first evaporator. The refrigerant after releasing heat is transported to the condenser fan 4, which cools it down until it becomes liquid. It then enters the second evaporator 12 through the expansion valve to absorb heat during evaporation, thereby absorbing heat from the water vapor in the condenser 3. The water vapor is then cooled to form distilled water, which is discharged through the clean water pipe 11 in conjunction with the vacuum generator 10 and the centrifugal pump 9. The clean water discharged through the centrifugal pump 9 is stored in the water tank 8. This equipment uses thermal circulation technology for evaporation. The treated ink can be reused after adding color paste.

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

[0047] Therefore, by setting up a flushing ring 20 and a cleaner 21, the water-based ink wastewater treatment equipment has a bidirectional flushing structure when in use, which can respectively complete the flushing operation of the inner wall of the first evaporator 14 and the inner wall of the distillation kettle 2, making it convenient to separate and treat water-based ink wastewater of different colors.

[0048] In use, the fixing base 17 fixes the first evaporator 14 from the bottom, so that the periphery of the first evaporator 14 does not contact the distillation vessel 2, allowing the rinsing ring 20 to move up and down through the first evaporator 14. One end of the hose 15 is passed through the slot of the distillation vessel 2, so that one end of the hose 15 is connected and fixed to the rinsing ring 20. The cleaning tank 23 provides cleaning fluid to the rinsing ring 20 through the hose 15. The user drives the lifting screw 19 to rotate by the motor, so that the lifting screw 19 drives the rinsing ring 20 to move up and down through the threaded structure, so that the rinsing ring 20 passes through the first evaporator 14. Using the nozzles 24 set inside and outside, the inner wall of the distillation vessel 2 and the outer surface of the first evaporator 14 can be rinsed simultaneously when the rinsing ring 20 moves up and down. Water can be supplied to the nozzles 24 through the annular pipe 25. When the cleaning tank 23 is opened, the pump 16 can be used to transport the cleaning fluid. When the water inlet pipe 22 is opened, the pump 16 can be used to transport clean water, which facilitates the rinsing of the inside of the distillation vessel 2 with clean water, thereby quickly completing the equipment cleaning operation.

[0049] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
