Description

Technical Field

[0001] This invention relates to the field of wastewater purification technology, specifically to an environmentally friendly purification machine for printing wastewater. Background Technology

[0002] During the printing production process, a large amount of printing wastewater is generated in steps such as plate cleaning, equipment rinsing, dampening solution replacement, and ink mixing. In order to prevent printing wastewater from polluting the surrounding water environment, it is usually purified before being discharged.

[0003] For example, a printing wastewater purification and reuse device with announcement number CN215516927U includes a treatment box. The central shaft is driven by a motor to rotate intermittently by a servo, which causes the wiping ring to rotate downwards and upwards. During the movement of the wiping ring, the mixing reaction of the wastewater is accelerated and the sedimentation efficiency of the wastewater is improved. After the wastewater settles, the upper clear water falls into the separation chamber together. At this time, the wiping ring moving up and down can clean the inner wall of the sedimentation chamber.

[0004] The existing technologies mentioned above have the following technical problems: When treating printing wastewater, the existing wastewater purification devices filter the wastewater and add chemicals for mixing and reaction. However, cleaning the filter screen and mixing the wastewater require two sets of equipment, namely, independent cleaning components and mixing components. Although the two sets of equipment can achieve the same function, the two independent sets of equipment require a large layout space and have low integration, which cannot be well adapted to some purification pools or purification devices with limited space.

[0005] Therefore, we propose an environmentally friendly purification and treatment machine for printing wastewater to solve the problems mentioned above. Summary of the Invention

[0006] The purpose of this invention is to provide an environmentally friendly purification treatment machine for printing wastewater, in order to solve the problem mentioned in the background art. Existing wastewater purification devices on the market treat printing wastewater by filtering the wastewater and adding chemicals for mixing and reaction. However, when cleaning the filter screen and mixing the wastewater, two sets of equipment are required, namely, independent cleaning components and stirring components. Although the two sets of equipment can achieve the same function, the two independent sets of equipment require a large layout space and have low integration, which makes them unsuitable for some purification tanks or purification devices with limited space.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an environmentally friendly purification machine for printing wastewater, comprising a purification body and an inlet fixed in the middle of the purification body, wherein a filter plate is fixed inside the inlet, a movable cover is installed at the lower end of the inlet, and the side of the movable cover is connected to a diversion cover via a connecting pipe, a first solenoid valve is installed on the connecting pipe, the diversion cover is fixed at the lower end of the movable cover, a concentrating plate is fixed at the end of the diversion cover away from the movable cover, and the side edge of the concentrating plate is mounted on a positioning ring fixed inside the purification body, wherein a [missing information] is fixed on the positioning ring. A filling branch pipe is provided, and a valve is installed on the filling branch pipe. The filling branch pipe is installed on the guide pipe, and a drug delivery pipe is fixed circumferentially on the guide pipe. A drain pipe is installed at the bottom of the collection plate, and a second solenoid valve is installed on the drain pipe. A limit post is installed at the upper end of the collection plate, and a power cylinder is connected to the upper end of the limit post. A piston disc is installed at the telescopic end of the power cylinder. The piston disc moves inside the limit post to control the movement of the pneumatic mixing vibration component on the diversion hood, so as to integrate the dual functions of intermittent knocking cleaning of the filter plate and thorough mixing of wastewater and chemical agents.

[0008] Preferably, the lower end of the movable cover is mounted on the output end of the servo motor, and the servo motor is fixed on the purifier body. The lower end of the purifier body is provided with a drain port for discharging the purified wastewater outward. The movable cover can rotate at the lower end of the liquid inlet.

[0009] By adopting the above technical solution, the servo motor can be activated to allow the movable cover to rotate at the bottom of the liquid inlet.

[0010] Preferably, the interiors of the diverter and the concentrator are interconnected, and the concentrator is rotatable on the positioning ring. A sealing ring is installed between the concentrator and the positioning ring.

[0011] By adopting the above technical solution, the sealing ring can ensure the sealing between the central plate and the positioning ring, while the rotation of the diversion hood and the central plate can facilitate the mixing of chemical agents and wastewater.

[0012] Preferably, there are multiple filling branch pipes evenly distributed on the positioning ring, and each filling branch pipe is connected to the guide pipe.

[0013] By adopting the above technical solution, the injection branch pipe can not only inject chemical agents into the inside of the central plate, but also mix the agents and wastewater inside when the diversion hood and the central plate rotate.

[0014] Preferably, the interior of the limiting post is a hollow structure, and the interiors of the limiting post and the concentrating disk are interconnected. The piston disk inside the limiting post is located at the lower opening of the limiting post in the initial state, and the piston disk is circumferentially wrapped with a sealing ring.

[0015] By adopting the above technical solution, the movement of the piston disc inside the limiting column facilitates the suction of wastewater from the central disc, allowing the wastewater to enter the interior of the limiting column.

[0016] Preferably, the pneumatic mixing vibration component includes a piston block installed inside the flow divider, and the piston block is circumferentially wrapped with a sealing ring. A mixing rod is fixed to the side of the piston block facing the concentrator. The piston block is connected to the flow divider via an internal spring, and the piston block and the flow divider form an air storage chamber. The air storage chamber is connected to a flow collector block inside the movable cover via a transmission pipe. A movable base plate is installed inside the flow collector block, and the movable base plate is also sealed to the flow collector block via a sealing ring. The movable base plate is connected to the flow collector block via a reset spring. A collision rod is provided above the movable base plate, and the collision rod is connected to the flow collector block via an auxiliary spring. A driving magnetic block is embedded in the lower end of the collision rod and the upper surface of the movable base plate.

[0017] By adopting the above technical solution, the reset spring facilitates the reset and rebound of the moving substrate after it has moved inside the current collector.

[0018] Preferably, the piston block and the flow divider are slidably connected, and the piston block and the mixing rod are vertically distributed, with at least one set of mixing rods provided on the piston block.

[0019] By adopting the above technical solution, the movement of the piston block inside the diversion hood can drive the mixing rod on it to move synchronously, thereby facilitating the mixing of chemical agents and wastewater.

[0020] Preferably, the movable substrate forms an elastic telescopic structure through a reset spring and a current collector, and multiple driving magnetic blocks are evenly distributed on the upper surface of the movable substrate.

[0021] By adopting the above technical solution, airflow is transmitted to the inside of the current collector through the transmission pipe, and the moving substrate can be driven to move in the current collector under the action of the airflow.

[0022] Preferably, the magnetic properties of the driving magnetic block on the upper surface of the movable substrate are opposite to those of the driving magnetic block at the lower end of the collision rod, and the upper end of the collision rod is in contact with the lower surface of the filter plate in the initial state.

[0023] By adopting the above technical solution, the collision rod can reciprocate under the magnetic force of the driving magnetic block and the action of the auxiliary spring through the movement of the moving substrate.

[0024] Compared with the prior art, the beneficial effects of the present invention are: the environmentally friendly purification treatment machine for printing wastewater integrates the functions of filter screen vibration cleaning and wastewater turbulence mixing into one unit. When adding wastewater, the pneumatic component can be used to continuously tap the filter screen. When mixing the reagents, the pneumatic component can be used to accelerate the mixing efficiency of wastewater and reagents. 1. Wastewater enters the collection plate and the inside of the diversion hood, which drives the piston block to move. The movement of the piston block forces the airflow inside the storage chamber into the collection block and pushes the moving plate to move. After the moving plate moves, the magnetic force of the driving magnet and the action of the auxiliary spring enable the collision rod to move up and down. The reciprocating movement of the collision rod impacts the filter plate. The vibration generated by the impact shakes out various impurities stuck in the holes of the filter plate, preventing the mesh from being blocked and affecting the water intake. 2. By utilizing the movement of the piston disc inside the limiting column, wastewater can enter the limiting column and then be squeezed out. This allows the piston block inside the diversion hood to move back and forth. Through the reciprocating movement of the piston block, the wastewater inside the diversion hood can be mixed and agitated by the mixing rod on the side. 3. The addition of branch pipes facilitates the addition of chemical agents to the central control plate. At the same time, when the central control plate rotates, the agents inside can be mixed and stirred by the branch pipes. Thus, the branch pipes can also act as a stirring component, improving the mixing effect of wastewater and chemical agents. Attached Figure Description

[0027] 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.

[0028] Example 1: Please refer to Figures 1-9Existing wastewater purification devices treat printing wastewater by filtering the wastewater and adding chemicals for mixing. However, cleaning the filter and mixing the wastewater require two separate sets of equipment: a cleaning unit and a mixing unit. While both sets achieve the same function, they require a large layout space and have low integration, making them unsuitable for space-constrained purification tanks or devices. To address this technical problem, this embodiment discloses the following: an environmentally friendly purification machine for printing wastewater, comprising a purification body 1 and an inlet 2 fixed in the middle of the purification body 1. A filter plate 3 is fixed inside the inlet 2. The lower end of the inlet 2... A movable cover 4 is installed, and the side of the movable cover 4 is connected to a diversion cover 6 via a connecting pipe 5. A first solenoid valve 12 is installed on the connecting pipe 5. The diversion cover 6 is fixed to the lower end of the movable cover 4. A concentrating plate 7 is fixed to the end of the diversion cover 6 away from the movable cover 4, and the side edge of the concentrating plate 7 is installed on a positioning ring 8 fixed inside the purification body 1. A filling branch pipe 9 is fixed to the positioning ring 8, and a valve is installed on the filling branch pipe 9. The filling branch pipe 9 is installed on a guide pipe 10, and a drug delivery pipe 11 is fixed circumferentially to the guide pipe 10. A drain pipe 13 is installed at the bottom of the concentrating plate 7, and a second solenoid valve 14 is installed on the drain pipe 13. A limit post 15 is installed at the upper end of the concentrating plate 7, and a power cylinder 16 is connected to the upper end of the limit post 15. A piston disc 17 is installed at the telescopic end of the 16. The piston disc 17 controls the movement of the pneumatic mixing vibration component on the diversion hood 6 by moving inside the limiting post 15, so as to integrate the dual functions of intermittent knocking cleaning of the filter plate 3 and thorough mixing of wastewater and chemical agents. The lower end of the movable hood 4 is installed on the output end of the servo motor 30, and the servo motor 30 is fixed on the purification body 1. The lower end of the purification body 1 is provided with a drain port 29 for discharging the purified wastewater. The movable hood 4 can rotate at the lower end of the liquid inlet 2. The interiors of the diversion hood 6 and the concentrating plate 7 are interconnected, and the concentrating plate 7 can rotate on the positioning ring 8. A sealing ring is installed between the concentrating plate 7 and the positioning ring 8. The interior of the limiting post 15 is set as a hollow structure. Furthermore, the interiors of the limiting post 15 and the concentrating disk 7 are interconnected. The piston disk 17 inside the limiting post 15 is initially located at the lower opening of the limiting post 15. A sealing ring surrounds the circumference of the piston disk 17. The pneumatic mixing vibration component includes a piston block 18 installed inside the flow divider 6, and the piston block 18 is also surrounded by a sealing ring. A mixing rod 19 is fixed to the side of the piston block 18 facing the concentrating disk 7. The piston block 18 is connected to the flow divider 6 via a built-in spring 20, and the piston block 18 and the flow divider 6 form an air storage chamber 21. The air storage chamber 21 is connected to the flow collector 23 inside the movable cover 4 via a transmission pipe 22. A movable base plate 24 is installed inside the flow collector 23, and the movable base plate 24 is also sealed to the flow collector 23 via a sealing ring.The movable substrate 24 is interconnected with the current collector 23 via a reset spring 25. A collision rod 26 is positioned above the movable substrate 24 and is interconnected with the current collector 23 via an auxiliary spring 27. Driving magnetic blocks 28 are embedded in the lower end of the collision rod 26 and the upper surface of the movable substrate 24. The piston block 18 and the flow divider 6 are slidably connected, and the piston block 18 and the mixing rod 19 are vertically distributed. At least one set of mixing rods 19 is provided on the piston block 18. The movable substrate 24 forms an elastic telescopic structure via the reset spring 25 and the current collector 23. Multiple driving magnetic blocks 28 are evenly distributed on the upper surface of the movable substrate 24. The magnetic properties of the driving magnetic blocks 28 on the upper surface of the movable substrate 24 are opposite to those of the driving magnetic blocks 28 at the lower end of the collision rod 26. Initially, the upper end of the collision rod 26 is in contact with the lower surface of the filter plate 3.

[0029] When printing wastewater needs purification, it is fed into the inlet 2. The wastewater is first filtered by the filter plate 3, and then enters the movable hood 4 and the diversion hood 6 and the collection plate 7 through the connecting pipe 5. As wastewater is added, the piston block 18 inside the diversion hood 6 is gradually moved. After the piston block 18 moves, it can squeeze the airflow inside the air storage chamber 21 into the collection block 23 through the transmission pipe 22. The increased airflow can drive the movable base plate 24 to move. After the movable base plate 24 moves, the driving magnetic block 2 on it... After the driving magnetic block 28 at the lower end of the collision rod 26 and the collision rod 26 approach each other, the collision rod 26 can move downward under the action of magnetic force. After the moving base plate 24 moves, the driving magnetic block 28 on it and the driving magnetic block 28 at the lower end of the collision rod 26 move away from each other. The collision rod 26 is reset and rebounded under the action of the auxiliary spring 27. Thus, the reciprocating movement of the collision rod 26 can be realized. The reciprocating movement of the collision rod 26 can impact the filter plate 3. The vibration generated by the impact on the filter plate 3 can shake out the impurities stuck in the mesh of the filter plate 3, preventing the mesh from being blocked and affecting the water intake. After filling the interiors of the diversion hood 6 and the concentrator 7 with wastewater, the first solenoid valve 12 on the connecting pipe 5 is closed. The delivery pipe 11 is then connected to the chemical supply equipment, and the chemical is delivered through the delivery pipe 11 to the guide pipe 10. The chemical inside the guide pipe 10 is then added to the concentrator 7 through the filling branch pipe 9. At this time, the servo motor 30 is turned on. After the servo motor 30 is turned on, the movable hood 4 drives the diversion hood 6 and the concentrator 7 to rotate synchronously. The rotation of the diversion hood 6 and the concentrator 7 mixes the wastewater and chemical inside. At the same time, the piston disc 17 is controlled by the power cylinder 16 to reciprocate inside the limit post 15. When the piston disc 17 moves upward inside the limit post 15, it allows the diversion hood 6 and the concentrator 7 to reciprocate. Water from inside the disc 7 enters the limiting post 15. After the water enters the limiting post 15, the piston block 18 will reset a certain distance under the action of the built-in spring 20. When the piston disc 17 moves downward inside the limiting post 15, it can squeeze the water from the limiting post 15 back into the concentrating disc 7. At this time, the piston block 18 will be pushed again. The reciprocating rotation of the piston block 18 can realize the reciprocating movement of the piston block 18. Through the reciprocating movement of the piston block 18, the mixing rod 19 on the side can be used to fully mix the wastewater and the agent inside. After the wastewater is treated for the second time, the second solenoid valve 14 on the drain pipe 13 is opened, and the wastewater in the diversion hood 6 and the concentrating disc 7 is discharged outward through the drain pipe 13 and the drain port 29 on the purification body 1.

[0030] Example 2: The technical content disclosed in this example is a further improvement based on Example 1 described above, such as... Figure 2 and Figure 7 As shown, the following technical content is disclosed in this embodiment: multiple filling branch pipes 9 are evenly distributed on the positioning ring 8, and each filling branch pipe 9 is interconnected with the guide pipe 10. The filling branch pipe 9 extends into the interior of the central plate 7.

[0031] By installing the injection branch pipe 9, chemical agents can be injected into the interior of the diversion hood 6 and the concentration plate 7. At the same time, because the injection branch pipe 9 extends into the interior of the concentration plate 7, when the diversion hood 6 and the concentration plate 7 rotate, the wastewater and chemical agents inside can also be stirred by the injection branch pipe 9. The injection branch pipe 9 can also act as a stirring and mixing component.

[0032] The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
