Description

Technical Field

[0001] This invention relates to the field of ink production technology, and in particular to an environmentally friendly reaction vessel for ink production with good purification effect. Background Technology

[0002] Printing ink is an essential material used in printing to transfer patterns and text onto a substrate through printing or inkjet printing. It consists of binders (resins), pigments, fillers, additives, and solvents, which are uniformly mixed and repeatedly rolled to form a viscous, colloidal fluid used in various printing applications, including books, packaging, architectural decoration, and electronic circuit boards. Pigments determine the color, binders (such as vegetable oils and resins) affect adhesion and drying properties, and additives adjust flowability and abrasion resistance. The preparation and mixing of these inks requires the use of environmentally friendly reaction vessels.

[0003] A search revealed a patent with publication number CN107952310A entitled "An Environmentally Friendly Reactor for Ink Production with Good Purification Effect." The patent addresses the technical problem of toxic gases generated during production, which harm the health of workers. Furthermore, the odor produced during ink production can easily cause dizziness, headaches, or blurred vision in workers during prolonged operation. The patent addresses this issue by using a fixed particle removal chamber and purification device. First, water mist is used to adsorb solid particles in the gas, removing them. Then, ozone water is used to disinfect and sterilize the gas. Next, activated carbon adsorption plates adsorb odors. Finally, heating rods dry the humid gas, and the clean gas is discharged, demonstrating strong environmental protection capabilities.

[0004] However, the following drawbacks still need to be addressed: as flue gas is produced, the activated carbon adsorption plate cannot maintain a high adsorption effect for a long time, and the bactericidal effect of ozone water also decreases as the flue gas containing water vapor reacts, making it impossible to maintain the flue gas purification efficiency and effect. Summary of the Invention

[0005] Based on the existing technical problems that cannot maintain the efficiency and effect of flue gas purification, this invention proposes an environmentally friendly reaction vessel for ink production with good purification effect.

[0006] This invention proposes an environmentally friendly reaction vessel for ink production with good purification effect, comprising a vessel body, an inlet pipe and an outlet pipe fixedly connected to the top of the vessel body, a mixing motor fixedly installed in the middle of the top of the vessel body, a discharge pipe fixedly connected to the bottom of the vessel body, a stirring assembly fixedly installed at the output end of the mixing motor, a spray box arranged on the outside of the vessel body, and a gas guide pipe fixedly connected between the inlet end of the spray box and the circumferential top of the outlet pipe, a purification box fixedly connected to the outlet end of the spray box through a pipe, a spray assembly arranged inside the spray box, and a [missing information - likely a device or component] fixedly installed at the upper end of the spray box.

An adsorption sleeve is slidably inserted into the horizontal section of the purification chamber, with a sealing frame at the inlet and a perforated plate at the outlet. The top of the adsorption sleeve has multiple equally spaced slots, and multiple U-shaped protrusions are provided between the inner wall of the bottom and the inner walls on both sides of the adsorption sleeve. Each U-shaped protrusion is located at the lower end of a slot in the same row. Multiple adsorption components are inserted into the adsorption sleeve.

[0007] Preferably, a drive motor is fixedly installed at the top of the exhaust pipe, and a central frame is fixedly installed at the output end of the drive motor. The central frame is located at the top inside the exhaust pipe, and three scraper blades with equal angles are fixedly installed on the outside of the central frame. The cross-section of the scraper blades is triangular, and a spiral reinforcing strip is inserted between the three scraper blades.

[0008] Preferably, the bottom of the spray box is a slope, and a drain pipe is fixedly installed at one bottom end of the spray box, with the drain pipe located at the lower end of the bottom of the spray box.

[0009] Preferably, the spray assembly includes a water inlet pipe, and a liquid distribution pipe is fixedly installed at the output end of the water inlet pipe. The liquid distribution pipe is located in the middle of the spray box, and a pair of spray nozzles are fixedly installed at the bottom end of the liquid distribution pipe. Multiple spray nozzles are fixedly installed around the circumference of the liquid distribution pipe. The center line of the outlet end of the pair of spray nozzles coincides with the center line of the outlet end of the air guide pipe, and the multiple spray nozzles are arranged in a spiral array.

[0010] Preferably, an exhaust port is fixedly provided at the top of the vertical section of the purification box, and a UV photolysis purification component is provided inside the vertical section of the purification box.

[0011] Preferably, the mesh cover cylinder is sleeved with the horizontal air inlet end of the purification box, and an annular groove is provided inside the mesh cover cylinder, and the annular groove is filled with desiccant.

[0012] Preferably, a condenser column is sealed and inserted at the top of the middle of the mesh cover cylinder, and a cold source pipe is fixedly installed at the top of the condenser column. Multiple heat transfer fins with equal angles are fixedly installed around the circumference of the condenser column, and the bottom of the circumference of the condenser column and the bottom of the multiple heat transfer fins are elliptical.

[0013] Preferably, a pull rod is fixedly installed in the middle of the outlet end of the adsorption sleeve, and a sealing cover is fixedly installed at the end of the pull rod. The length and width of the sealing cover are both greater than the second insertion port, and the sealing cover is fixedly installed on the outside of the second insertion port.

[0014] Preferably, the adsorption element includes a frame, with the top of the frame sealed to the slot, and the bottom and both ends of the frame sealed to the U-shaped protrusion. The frame is filled with activated carbon adsorbent, and the middle of both ends of the frame is provided with activated carbon fiber mesh.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. This invention proposes an environmentally friendly reaction vessel for ink production with good purification effect. The vessel mixes the ink binder (resin), pigments, fillers, additives, and solvents inside. The resulting flue gas is discharged through an exhaust pipe and passes sequentially through a spray box, a horizontal section of the purification box, and a vertical section of the purification box. Water mist settles particulate matter in the flue gas and lowers its temperature. Multiple adsorbents adsorb volatile organic pollutants, and a UV photolysis purification component decomposes them, ensuring that the exhaust gas from the purification box is superior to emission standards. Settled particulate matter and wastewater at the bottom of the spray box can be discharged through a drain pipe. The condensed droplets from the condenser column fall into the spray box. The adsorption sleeve can be removed from the horizontal section of the purification box. Multiple adsorbents are inserted into the adsorption sleeve, allowing for quick and easy replacement of the adsorbents. This ensures a highly efficient and long-term purification effect on the flue gas.

[0017] 2. The present invention proposes an environmentally friendly reaction vessel for ink production with good purification effect. By driving the motor to start working periodically, the central frame can rotate with three scrapers inside the exhaust pipe. The triangular cross section of the scraper helps to scrape off particulate matter from the inner wall of the exhaust pipe, avoiding long-term accumulation of particulate matter in the flue gas and causing poor flue gas exhaust. In addition, the three scrapers are connected with spiral reinforcing strips, which helps the three scrapers to rotate and scrape off particulate matter in a long-term and stable manner.

[0018] 3. This invention proposes an environmentally friendly reaction vessel for ink production with good purification effect. A stable water flow is continuously delivered into the distributor pipe through the inlet pipe. The center lines of the nozzle outlet at the bottom of the distributor pipe and the outlet of the gas guide pipe coincide. Multiple spray nozzles on the circumference of the distributor pipe are arranged in a spiral array, allowing the flue gas exiting the gas guide pipe to first collide with the water mist sprayed from the nozzles, facilitating rapid settling of particulate matter in the flue gas and reducing its temperature. The rising flue gas then passes through the water mist sprayed from the multiple nozzles, causing fine particles to combine with the water mist and settle. Next, a swirl plate removes the water mist from the rising airflow, leaving condensed droplets around the perimeter of the swirl plate. Finally, the gas is further purified by… A condenser column is installed in the middle of the mesh cover cylinder. The annular groove of the mesh cover cylinder is filled with desiccant, so that the airflow escaping from the spray box is cooled first, and the water mist in the airflow is re-condensed. The bottom of the condenser column and the bottom of multiple heat transfer fins are elliptical, which helps the droplets condensed by the airflow to fall freely. Then the airflow escapes from the mesh cover cylinder, and the desiccant comes into full contact with the airflow to further remove the water vapor in the airflow. In addition, multiple heat transfer fins with equal angles are fixedly installed on the circumference of the condenser column to increase the cooling area of ​​the airflow and expand the cold source diffusion area, so that the airflow introduced into the adsorption unit is dry, and avoids the water vapor in the airflow from affecting the efficient adsorption of volatile organic pollutants by the activated carbon adsorbent.

[0028] Reference Figure 1-8 An environmentally friendly reaction vessel for ink production with good purification effect includes a vessel body 1. A feed pipe 2 and an exhaust pipe 3 are fixedly connected to the top of the vessel body 1. A mixing motor 4 is fixedly installed in the middle of the top of the vessel body 1. A discharge pipe 5 is fixedly connected to the bottom of the vessel body 1. A stirring assembly is fixedly installed at the output end of the mixing motor 4, which helps to quickly and uniformly mix the binder (resin), pigment, filler, additives, and solvent of the ink. A spray box 9 is provided on the outside of the vessel body 1, and a gas guide pipe 10 is fixedly connected between the inlet end of the spray box 9 and the circumferential top of the exhaust pipe 5. A purification box 11 is fixedly connected to the outlet end of the spray box 9 through a pipe. A spray assembly is provided inside the spray box 9. The upper part of the inside of the spray box 9 is fixedly... The purification box 11 is L-shaped and has a swirl plate 18 installed. The top of the horizontal section of the purification box 11 has a first inlet 19 and the bottom of the vertical section of the purification box 11 has a second inlet 25. A mesh cover cylinder 20 is inserted into the first inlet 19. An adsorption sleeve 28 is slidably inserted into the horizontal section of the purification box 11. A sealing frame 29 is provided at the inlet end of the adsorption sleeve 28 and a hollow plate 34 is provided at the outlet end of the adsorption sleeve 28. The top of the adsorption sleeve 28 has multiple equally spaced slots 30. Multiple U-shaped protrusions 31 are provided between the inner wall of the bottom end of the adsorption sleeve 28 and the inner walls of both sides. Each U-shaped protrusion 31 is located at the lower end of the slot 30 in the same row. Multiple adsorption components are inserted into the adsorption sleeve 28.

[0029] In this invention, a drive motor 6 is fixedly installed at the top of the exhaust pipe 5, and a central frame is fixedly installed at the output end of the drive motor 6. The central frame is located at the top inside the exhaust pipe 5, and three scraper strips 7 with equal angles are fixedly installed on the outside of the central frame. The cross-section of the scraper strips 7 is triangular, and a spiral reinforcing strip 8 is inserted between the three scraper strips 7. By periodically starting the drive motor 6, the central frame can rotate with the three scraper strips 7 inside the exhaust pipe 5. The triangular cross-section of the scraper strips 7 helps to scrape off the particulate matter on the inner wall of the exhaust pipe, avoiding the long-term accumulation of smoke particulate matter that leads to poor exhaust. The spiral reinforcing strip 8 inserted between the three scraper strips 7 helps the three scraper strips 7 to rotate and scrape off particulate matter in a long-term and stable manner.

[0030] The bottom of the spray box 9 is a slope. A sewage pipe 14 is fixedly installed at one bottom end of the spray box 9. The sewage pipe 14 is located at the lower end of the bottom of the spray box 9, which helps to discharge flue gas particles, sedimented particles combined with water vapor, and sewage in a timely manner.

[0031] The spray assembly includes a water inlet pipe 13, and a distribution pipe 15 is fixedly installed at the output end of the water inlet pipe 13. The distribution pipe 15 is located in the middle of the spray box 9. A pair of spray nozzles 16 are fixedly installed at the bottom end of the distribution pipe 15. Multiple spray nozzles 17 are fixedly installed around the circumference of the distribution pipe 15. The center line of the outlet end of the pair of spray nozzles 16 coincides with the center line of the outlet end of the air guide pipe 10. The multiple spray nozzles 17 are arranged in a spiral array, continuously delivering a stable water flow into the distribution pipe 15 through the water inlet pipe 13. The center lines of the outlet end of the nozzle 16 and the outlet end of the air duct 10 are aligned. The multiple spray nozzles 17 around the circumference of the liquid distribution pipe 15 are arranged in a spiral array, so that the flue gas discharged from the air duct 10 first comes into full contact with the water mist sprayed from the nozzle 16, which helps the particulate matter in the flue gas to settle quickly and reduce the temperature of the flue gas. Then, the rising flue gas passes through the water mist sprayed by the multiple spray nozzles 17, and the fine particulate matter combines with the water mist and settles. The swirl plate 18 removes the water mist in the rising airflow.

[0032] An exhaust port 12 is fixedly installed at the top of the vertical section of the purification box 11. The vertical section of the purification box 11 is equipped with a UV photolysis purification component. The UV photolysis technology uses high-energy ultraviolet light to break down large molecular compounds (such as benzene series compounds, hydrogen sulfide, etc.) in oil fumes or exhaust gases, converting them into harmless substances such as carbon dioxide and water. At the same time, the ozone generated can deeply oxidize residual odors and bacteria, and can break down the residual volatile organic pollutants in the flue gas, ensuring that the exhaust gas flow is better than the emission standards.

[0033] The mesh cover cylinder 20 is sleeved with the horizontal section of the air inlet end of the purification box 11. The mesh cover cylinder 20 has an annular groove 21 inside, and the annular groove 21 is filled with desiccant. A condenser column 22 is set in the middle of the mesh cover cylinder 20. The annular groove 21 of the mesh cover cylinder 20 is filled with desiccant, so that the airflow escaping from the spray box 9 is cooled first, and the water mist in the airflow is condensed again. Then the airflow escapes from the mesh cover cylinder 20, and the desiccant comes into full contact with the airflow to further remove the water vapor in the airflow. In addition, multiple heat transfer fins 23 with equal angles are fixedly installed on the circumference of the condenser column 22 to increase the cooling area of ​​the airflow and expand the cold source diffusion area. The bottom of the circumference of the condenser column 22 and the bottom of the multiple heat transfer fins 23 are elliptical, which helps the droplets condensed by the airflow to fall freely.

[0034] A condenser column 22 is sealed and inserted at the top of the middle of the mesh cylinder 20, and a cold source pipe 24 is fixedly installed at the top of the condenser column 22. Multiple heat transfer fins 23 at equal angles are fixedly installed on the circumference of the condenser column 22, and the bottom of the circumference of the condenser column 22 and the bottom of the multiple heat transfer fins 23 are elliptical.

[0035] A pull rod 27 is fixedly installed in the middle of the outlet end of the adsorption sleeve 28, and a sealing cover plate 26 is fixedly installed at the end of the pull rod 27. The length and width of the sealing cover plate 26 are both greater than the second inlet 25. The sealing cover plate 26 is fixedly installed on the outside of the second inlet 25, which facilitates the adsorption sleeve 28 to be moved into and out of the purification box 11.

[0036] The adsorption element includes a frame 32, with the top of the frame 32 sealed to the slot 30, and the bottom and both ends of the frame 32 sealed to the U-shaped protrusion 31. The frame 32 is filled with activated carbon adsorbent, and the middle of both ends of the frame 32 is set with activated carbon fiber mesh 33. The airflow passes through multiple adsorption elements in the horizontal section of the purification box 11, and then flows to the UV photolysis purification component in the vertical section of the purification box 11, so that the volatile organic pollutants in the airflow are first adsorbed and then decomposed, ensuring that the discharged airflow is better than the emission standards.

[0037] Working principle: The binder (resin), pigment, filler, additives and solvent of the ink are stirred and mixed inside the vessel 1. The flue gas generated during the mixing process is discharged from the exhaust pipe 5 and passes through the spray box 9, the horizontal section of the purification box 11 and the vertical section of the purification box 11 in sequence. The water mist settles the particulate matter in the flue gas and reduces the temperature of the flue gas. Multiple adsorbents adsorb and UV photolysis purification components decompose volatile organic pollutants, so that the airflow discharged from the purification box 11 is better than the emission standards. The settled particulate matter and sewage at the bottom of the spray box 9 can be discharged from the drain pipe 14. The condensed droplets of the condenser column 22 fall into the interior of the spray box 9. The adsorption sleeve 28 can be removed from the horizontal section of the purification box 11. Multiple adsorbents are inserted into the adsorption sleeve 28, which makes it easy to replace the adsorbents quickly, thereby maintaining a high efficiency and long-term purification effect on the flue gas.

[0038] By periodically starting the drive motor 6, the central frame can rotate inside the exhaust pipe 5 with the three scraper blades 7. The triangular cross section of the scraper blades 7 helps to scrape off the particulate matter on the inner wall of the exhaust pipe, avoiding the long-term accumulation of smoke particulate matter that leads to poor exhaust. In addition, the three scraper blades 7 are connected by a spiral reinforcing strip 8, which helps the three scraper blades 7 to rotate and scrape off particulate matter in a long-term and stable manner.

[0039] A stable water flow is continuously supplied into the distribution pipe 15 through the inlet pipe 13. The center line of the outlet end of the nozzle 16 at the bottom of the distribution pipe 15 coincides with the center line of the outlet end of the air guide pipe 10. Multiple spray nozzles 17 around the circumference of the distribution pipe 15 are arranged in a spiral array, so that the flue gas discharged from the air guide pipe 10 first comes into full contact with the water mist sprayed from the nozzles 16, which helps the particulate matter in the flue gas to settle quickly and reduce the temperature of the flue gas. Then, the rising flue gas passes through the water mist sprayed by multiple spray nozzles 17. The fine particles combine with the water mist and settle down. Then, the swirl plate 18 removes the water mist from the rising airflow, so that the condensed droplets leave from the periphery of the swirl plate 18. Then, because a cooling device is set in the middle of the mesh cover cylinder 20, the flue gas is further cooled. The annular groove 21 of the condenser column 22 and the mesh cover cylinder 20 is filled with desiccant, which allows the airflow escaping from the spray box 9 to be cooled first, causing the water mist in the airflow to condense again. The bottom of the circumference of the condenser column 22 and the bottom of the multiple heat transfer fins 23 are elliptical, which helps the droplets condensed by the airflow to fall freely. Then the airflow escapes from the mesh cover cylinder 20, and the desiccant comes into full contact with the airflow to further remove water vapor from the airflow. In addition, multiple heat transfer fins 23 with equal angles are fixedly installed on the circumference of the condenser column 22 to increase the cooling area of ​​the airflow and expand the cold source diffusion area, so that the airflow introduced into the adsorption sleeve 28 is dry, avoiding the water vapor in the airflow from affecting the efficient adsorption of volatile organic pollutants by the activated carbon adsorbent.
