Description

Technical Field

[0001] This invention relates to the field of anthraquinone purification technology, and more particularly to an anthraquinone purification apparatus. Background Technology

[0002] Anthraquinone is a synthetic natural dye. The basic nucleus of anthraquinone compounds is anthraquinone, which often has substituents such as hydroxyl, hydroxymethyl, methyl, methoxy and carboxyl groups. In a solvent, it is hydrogenated to produce 2-ethylanthraquinone, and upon re-oxidation, it regenerates 2-ethylanthraquinone and hydrogen peroxide. This reaction is used industrially to produce hydrogen peroxide.

[0003] Currently, the production of anthraquinone requires purification by distillation. However, during the purification process, the steam generated inside the distillation cylinder comes into contact with the top of the cylinder as it rises, condensing into water droplets.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1. In this invention, after steam is generated inside the distillation cylinder, the steam flows upward to the top of the distillation cylinder and is discharged from the top of the distillation cylinder. When the steam is discharged, the water mist in the steam is filtered by the flow guiding device to condense the water mist. During the steam discharge process, the steam provides power to the drive device, which then works to guide the condensed water flow into the collection device. After the collection device is full of water flow, the collected water flow is discharged. At the same time, the reaction force acts on the drive device to discharge the impurities deposited on the bottom surface of the distillation cylinder. 2. When the drive device in this invention is working, the exhaust airflow drives the vortex blades to rotate, which in turn drives the drive shaft to rotate and drive multiple stirring blades to stir the liquid inside the distillation cylinder, so that the liquid forms a vortex inside the distillation cylinder. This allows the liquid to be heated evenly, while also allowing impurities in the liquid to gather towards the bottom center. 3. When the flow guiding device of the present invention is working, the water mist in the steam is condensed by the wire mesh cotton pad, so that the water vapor is condensed into water flow inside the wire mesh cotton pad. Then, the pressure roller rolls along the inner side of the wire mesh cotton pad to press the wire mesh cotton pad, and the water flow condensed inside the wire mesh cotton pad is pressed out along the flow guiding channel. Then, it flows out from the bottom of the pressure roller and the arc-shaped support plate to the collection device for collection. 4. When the collection device of the present invention is working, the position of the floating ring and the samarium cobalt magnetic ring is controlled by the liquid level in the annular storage tank, thereby controlling the adsorption of the samarium cobalt magnetic ring on the wear-resistant magnetic head at the end of the elastic support plate, so as to control the constraint on the annular sliding sleeve, so as to achieve the purpose of collecting the liquid in the annular storage tank and then discharging the liquid.

Detailed Implementation

[0018] 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.

[0019] Please see Figure 1-10The present invention provides a technical solution: an anthraquinone purification device, including a distillation cylinder 1, the top and bottom of the distillation cylinder 1 are closed, and the inner top surface of the distillation cylinder 1 is conical. An annular cavity 23 is formed between the inner side walls of the distillation cylinder 1 near the top edge. One side of the top of the annular cavity 23 extends into the distillation cylinder 1. A collecting device is provided inside the annular cavity 23. A driving device is provided inside the distillation cylinder 1. A flow guiding device is provided on the inner top surface of the distillation cylinder 1. A gas outlet pipe 4 is fixed at the top of the distillation cylinder 1, and a sewage pipe 8 connected to the interior is fixed at the bottom of the distillation cylinder 1. A water inlet pipe 2 is fixedly connected to one side of the distillation cylinder 1 near the bottom edge. A bent cavity 17 is opened between the inner walls of the distillation cylinder 1 near the bottom edge. A bent heating plate 18 is installed inside the bent cavity 17. A bent heat conducting plate 19 is installed between the inner walls of the bent cavity 17. One outer surface of the bent heat conducting plate 19 is aligned with the inner wall of the distillation cylinder 1. A return pipe 3 is fixed to both outer surfaces of the distillation cylinder 1. A side opening 22 connected to the return pipe 3 is opened on the outer inner wall of the annular cavity 23 near both edges. An inner cavity 10 is opened between the inner walls of the distillation cylinder 1 near the top. Multiple gas outlets 9 that penetrate into the gas outlet pipe 4 are equidistantly opened along the circumferential direction on the inner top surface of the inner cavity 10.

[0020] The effect is that after steam is generated inside the distillation cylinder 1, the steam will flow upwards from the top of the distillation cylinder 1 and be discharged from the top. When the steam is discharged, the water mist in the steam is filtered by the flow guiding device, causing the water mist to condense. During the steam discharge process, it will provide power to the drive device, causing the drive device to work and guide the condensed water flow into the collection device. After the collection device is full of water flow, it will discharge the collected water flow, and at the same time, it will react with the drive device to discharge the impurities deposited on the bottom surface of the distillation cylinder 1.

[0021] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 8As shown, the driving device includes a drive shaft 28. An annular constraint opening 43 is provided on the outer surface of the drive shaft 28 near its top edge. The top of the drive shaft 28 slides through to the top of the distillation cylinder 1. The annular constraint opening 43 is slidably engaged with the sliding penetration portion between the distillation cylinder 1 and the drive shaft 28. The bottom of the drive shaft 28 extends into the interior of the drain pipe 8, and the outer surface of the drive shaft 28 is slidably and sealingly fitted with the inner wall of the drain pipe 8. Multiple fan-shaped grooves 26 are equidistantly spaced along the circumferential direction on the inner bottom surface of the distillation cylinder 1. A sealing sleeve 27 is fixed to the inner bottom surface of the distillation cylinder 1, with one side of each of the multiple fan-shaped grooves 26 located at the bottom of the sealing sleeve 27. It extends into the drain pipe 8. The sealing sleeve 27 is slidably and sealingly fitted onto the outer surface of the drive shaft 28. A bottom groove 30 is provided at the bottom of the drive shaft 28. Multiple grid openings 31 extending to the outside are equidistantly provided along the circumferential direction between the inner walls of the bottom groove 30 near the top edge. Multiple stirring blades 16 are fixed equidistantly along the circumferential direction on the outer surface of the drive shaft 28. Multiple vortex blades 7 are fixed equidistantly along the circumferential direction on the outer surface of the drive shaft 28 near the top edge. An annular opening 5 is provided between the inner walls of the air outlet pipe 4. An annular ring 6 is slidably provided between the inner walls of the annular opening 5. One end of each of the multiple vortex blades 7 is fixed on the inner wall of the annular ring 6.

[0022] The effect achieved is that the steam generated by distillation is discharged from the outlet 9 through the inner cavity 10. When the steam is discharged from the outlet 9, it blows towards the vortex blades 7, thereby driving the vortex blades 7 to rotate. When the vortex blades 7 rotate, they drive the drive shaft 28 to rotate. When the drive shaft 28 rotates, it drives multiple stirring blades 16 to stir the liquid inside the distillation cylinder 1, so that the liquid forms a vortex inside the distillation cylinder 1. This can make the liquid heat evenly, and can also collect impurities in the liquid to the bottom center. In addition, when the drive shaft 28 rotates, it can also drive the flow guiding device to work.

[0023] like Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 10As shown, the collecting device includes an annular sleeve 32, which is slidably sealed between the inner walls of the two sides of the annular cavity 23. Annular storage grooves 33 are provided at both the top and bottom of the annular sleeve 32. A spring 24 is fixed to the bottom surface of the annular storage groove 33 at the bottom of the annular sleeve 32, with the bottom of the spring 24 fixed to the bottom surface of the annular cavity 23. Bridge interfaces 35 are provided on the inner walls of the annular storage groove 33 at the top of the annular sleeve 32, extending to the outer surface of the annular sleeve 32. Guide ports 25 extending into the interior of the distillation cylinder 1 are provided near the edges of the inner walls of the annular cavity 23. Support rods 15 are slidably arranged between the inner walls of the two guide ports 25. A retaining ring 14 is rotatably engaged on the outer surface of the drive shaft 28, with one end of each support rod 15 correspondingly fixed to the outer surface of the retaining ring 14. The other ends of the two support rods 15 are fixed to the annular sliding sleeve 32. A floating ring 41 is slidably fitted between the inner walls of the annular storage groove 33 at the top of the annular sliding sleeve 32. A samarium cobalt magnetic ring 42 is embedded between the inner walls of the floating ring 41. A storage opening 29 is opened on both sides of the inner wall of the annular sliding sleeve 32 near the top and the middle. An elastic support plate 21 is fixedly inclined on the bottom surface of the inner surface of the two storage openings 29. One end of the elastic support plate 21 at the top of the annular sliding sleeve 32 extends downward at an angle, and one end of the elastic support plate 21 at the middle of the annular sliding sleeve 32 extends upward at an angle. A wear-resistant magnetic head 40 is fixed to one end of each of the two elastic support plates 21. Limiting openings 34 are opened on both sides of the inner wall of the annular cavity 23 near the top and above the guide opening 25. One end of each limiting opening 34 is inclined. Both wear-resistant magnetic heads 40 extend into the limiting opening 34.

[0024] The effect achieved is that when there is no water flow inside the annular storage tank 33, the elastic force of the spring 24 pushes the annular sleeve 32 to the top surface inside the annular storage tank 33. At this time, the bridge interface 35 is located above the side opening 22, and the bridge interface 35 and the side opening 22 are misaligned and do not conduct. The grid opening 31 is located inside the sealing sleeve 27, and the sealing sleeve 27 seals the grid opening 31. At the same time, the elastic support piece 21 near the top of the annular sleeve 32 is engaged inside the limiting opening 34 near the top of the annular cavity 23. At this time, the elastic support piece 21 located in the middle of the annular sleeve 32 is located between the two limiting openings 34 and slides against the inner wall of the annular cavity 23. When water flows into the annular storage tank 33... During the inflow and storage process, the weight of the annular sliding sleeve 32 increases. Under the constraint of the wear-resistant magnetic head 40 at one end of the elastic support plate 21 near the top of the annular sliding sleeve 32 and the limiting port 34, the annular sliding sleeve 32 is prevented from sliding downwards. Furthermore, inside the annular storage tank 33, the rising water level causes the float ring 41 to slide upwards. When the float ring 41 slides to the top of the annular storage tank 33, the water inside the annular storage tank 33 is full. When the float ring 41 slides to the top of the annular storage tank 33, its internal samarium cobalt magnetic ring 42 is located on the side of the elastic support plate 21 near the top of the annular sliding sleeve 32. The magnetic attraction of the samarium cobalt magnetic ring 42 then engages the wear-resistant magnetic head 40 at the end of the elastic support plate 21. The adsorption process allows the wear-resistant magnetic head 40 at the end of the elastic support plate 21 to slide out from the limiting port 34, thereby releasing the support and limiting of the annular sleeve 32. This allows the annular sleeve 32 to slide downwards and compress the spring 24. After the annular sleeve 32 slides downwards into place, one end of the elastic support plate 21 located in the middle is engaged in the limiting port 34 above the guide port 25 by the wear-resistant magnetic head 40. At the same time, the bridge interface 35 is connected to the side port 22, allowing the liquid inside the annular storage tank 33 to flow from the side port 22 into the return pipe 3 for discharge. During the liquid outflow process, the mass of the annular sleeve 32 becomes lighter. However, under the constraint of the wear-resistant magnetic head 40 and the guide port 25, the elastic force generated by the spring 24 cannot compress the annular sleeve 32. 2. When the liquid in the annular storage tank 33 is drained, the floating ring 41 slides down to the bottom of the annular storage tank 33. At this time, the samarium cobalt magnetic ring 42 is located on one side of the elastic support plate 21 in the middle. The samarium cobalt magnetic ring 42 attracts the wear-resistant magnetic head 40, which can release the constraint on the annular sliding sleeve 32. At this time, the spring 24 can drive the annular sliding sleeve 32 to slide upward and reset. When the annular sliding sleeve 32 slides downward, the drive shaft 28 is driven to slide downward through the support rod 15 and the retaining ring 14, so that the grid opening 31 slides to be opposite to the fan-shaped groove 26 below the sealing sleeve 27. At this time, the dirt deposited on the bottom surface of the distillation cylinder 1 can flow into the grid opening 31 through the fan-shaped groove 26 and finally be discharged through the bottom groove 30.

[0025] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 9 As shown, the flow guiding device includes a wire mesh pad 13. An installation groove 12 is provided on the inner top surface of the distillation cylinder 1. The wire mesh pad 13 is installed inside the installation groove 12. Multiple strip-shaped openings 11 that penetrate into the inner cavity 10 are provided at equal intervals along the circumferential direction on the inner bottom surface of the installation groove 12. Multiple drains 20 are provided at equal intervals along the circumferential direction on the inner bottom surface of the inner cavity 10. The bottom of each drain 20 penetrates into one side of the inner cavity 23. Multiple arc-shaped support plates 39 are provided at equal intervals along the circumferential direction on the upper part of the inner surface of the distillation cylinder 1. The multiple arc-shaped support plates 39 are all inclined. Pressure rollers 37 are rotatably arranged between the inner walls on both sides of the multiple arc-shaped support plates 39. Flow guiding channels 38 are provided on the outer surface of the multiple pressure rollers 37. Connecting rods 36 are fixed at both ends of the multiple arc-shaped support plates 39. One end of each connecting rod 36 is fixed on the drive shaft 28. The pressure rollers 37 roll and press against the wire mesh pad 13. One end of the arc-shaped support plate 39 extends above the annular cavity 23.

[0026] The effect is that when steam enters the inner cavity 10 from the distillation cylinder 1, it first needs to pass through the wire mesh pad 13. Under the action of the wire mesh pad 13, the water mist in the steam is condensed, and the water vapor is condensed into water flow inside the wire mesh pad 13. When the drive shaft 28 rotates, it drives the arc-shaped support plate 39 to slide along the inner side of the wire mesh pad 13 circumferentially through the connecting rod 36. During the sliding process, it will drive the pressure roller 37 to roll along the inner side of the wire mesh pad 13 to press the wire mesh pad 13. During the pressing process, the water flow condensed in the wire mesh pad 13 is pressed out. The pressed water flow flows out from the bottom of the pressure roller 37 and the arc-shaped support plate 39 under the guidance of the guide channel 38 to the collection device for collection.

[0027] Working principle: The liquid to be distilled and purified is injected into the distillation cylinder 1 through the water inlet pipe 2. Heat is generated inside the distillation cylinder 1 by the bent heating plate 18. The heat is transferred to the liquid inside the distillation cylinder 1 through the bent heat conduction plate 19, causing the liquid to distill. The steam generated by distillation is discharged from the outlet 9 through the inner cavity 10. When the steam is discharged from the outlet 9, it blows towards the vortex blades 7, thereby driving the vortex blades 7 to rotate. When the vortex blades 7 rotate, they drive the drive shaft 28 to rotate. When the drive shaft 28 rotates, it drives multiple stirring blades 16 to stir the liquid inside the distillation cylinder 1, causing the liquid to form a vortex rotation inside the distillation cylinder 1. This allows the liquid to be heated evenly, and also allows impurities in the liquid to collect at the bottom center. Steam enters from the distillation cylinder 1. When the water vapor passes through the inner cavity 10, it first needs to pass through the mesh cotton pad 13. Under the action of the mesh cotton pad 13, the water vapor in the steam is condensed, causing the water vapor to condense into water flow inside the mesh cotton pad 13. When the drive shaft 28 rotates, it drives the arc-shaped support plate 39 to slide along the inner side of the mesh cotton pad 13 circumferentially through the connecting rod 36. During the sliding process, it will drive the pressure roller 37 to roll along the inner side of the mesh cotton pad 13, pressing the mesh cotton pad 13. During the pressing process, the water flow condensed inside the mesh cotton pad 13 is pressed out. The pressed water flow flows out from the bottom of the pressure roller 37 and the arc-shaped support plate 39 under the guidance of the guide channel 38 to the collection device for collection. When there is no water flow stored inside the annular storage tank 33, the annular sliding sleeve 32 is pushed to the top inside the annular storage tank 33 under the action of the elastic force of the spring 24. At this point, the bridge interface 35 is located above the side opening 22, and the bridge interface 35 and the side opening 22 are misaligned and non-conductive. The grid opening 31 is located inside the sealing sleeve 27, which seals the grid opening 31. At the same time, the elastic support piece 21 near the top of the annular sliding sleeve 32 is engaged inside the limiting opening 34 near the top of the annular cavity 23. The elastic support piece 21 located in the middle of the annular sliding sleeve 32 is between the two limiting openings 34 and slides against the inner wall of the annular cavity 23. As water flows into the annular storage tank 33, the weight of the annular sliding sleeve 32 increases. Under the constraint of the wear-resistant magnetic head 40 at one end of the elastic support piece 21 near the top of the annular sliding sleeve 32 being engaged with the limiting opening 34, the weight of the annular sliding sleeve 32 increases. As the water level rises inside the annular storage tank 33, the float ring 41 slides upward. When the float ring 41 reaches the top of the annular storage tank 33, the water inside the annular storage tank 33 is full. At this point, the samarium cobalt magnetic ring 42 inside the float ring 41 is located near the elastic support plate 21 at the top of the annular sleeve 32. The magnetic attraction of the samarium cobalt magnetic ring 42 attracts the wear-resistant magnetic head 40 at the end of the elastic support plate 21, allowing the wear-resistant magnetic head 40 to slide out from the limiting port 34. This releases the support and limiting of the annular sleeve 32, causing the annular sleeve 32 to slide downward and compress the spring 24. After the annular sleeve 32 slides downward into place...At this time, one end of the elastic support plate 21 located in the middle is engaged with the limiting port 34 above the guide port 25 by the wear-resistant magnetic head 40. At the same time, the bridge interface 35 is connected to the side port 22, allowing the liquid inside the annular storage tank 33 to flow from the side port 22 into the return pipe 3 for discharge. During the liquid outflow process, the mass of the annular sliding sleeve 32 becomes lighter. However, under the constraint of the wear-resistant magnetic head 40 and the guide port 25, the elastic force generated by the spring 24 cannot push the annular sliding sleeve 32 upward to reset. When the liquid in the annular storage tank 33 is drained, the floating ring 41 slides downward to the bottom surface inside the annular storage tank 33. At this point, the samarium cobalt magnetic ring 42 is located on one side of the elastic support plate 21 in the middle. The samarium cobalt magnetic ring 42 attracts the wear-resistant magnetic head 40, releasing the constraint on the annular sliding sleeve 32. The spring 24 then drives the annular sliding sleeve 32 to slide upwards and reset. When the annular sliding sleeve 32 slides downwards, the support rod 15 and the retaining ring 14 drive the drive shaft 28 downwards, causing the grid opening 31 to slide until it aligns with the fan-shaped groove 26 below the sealing sleeve 27. At this point, the dirt deposited on the bottom surface of the distillation cylinder 1 flows into the grid opening 31 through the fan-shaped groove 26 and is finally discharged through the bottom groove 30.

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.
