Description

Technical Field

[0001] The present invention relates to the technical field of ethanol recovery, and particularly to an ethanol recovery device for an aqueous ink printing oven. Background Art

[0002] In the aqueous ink printing process, printed products need to be heated and dried in an oven. Although ethanol added during ink manufacturing can improve the drying efficiency, it causes the baking exhaust gas to contain ethanol components and cannot be directly discharged. Therefore, an ethanol recovery device needs to be configured to achieve the resource recovery of ethanol in the exhaust gas.

[0003] Chinese invention application with publication number CN107297125A discloses an ethanol recovery device for an aqueous ink printing oven, including a sealed container, which has a mixed air cavity and a mixed gas-liquid cavity inside; the mixed air cavity has an intake pipe for communicating with the exhaust gas discharged from the aqueous ink printing oven. In the above prior art, the good miscibility of water and ethanol is used, and through gas-liquid mixing, the purpose of recovering ethanol in the oven exhaust gas is achieved, which is economical, energy-saving, and operable. However, this will result in the use of a large amount of water, causing waste of water resources;

[0004] In the prior art, the characteristic that the temperature required for ethanol in the exhaust gas to become liquid is higher than that of water vapor is also utilized. The temperature of the condensation unit is set within a suitable range, so that ethanol in the exhaust gas turns into a liquid phase, while water vapor remains in a gas phase, thereby a large amount of ethanol can be recovered. Subsequently, the remaining exhaust gas is further processed by activated carbon fibers to recover ethanol, thus completing the ethanol recovery process. However, the exhaust gas composition is complex. In addition to water vapor and ethanol, it also contains some ink impurities. These impurities will adhere to the condensation pipes of the condensation unit along with the exhaust gas, resulting in a large amount of dirt on the condensation pipes, thereby affecting the normal operation of the condensation unit and reducing the ethanol recovery efficiency and the service life of the equipment.

[0029] Compared with the prior art, the above technical solutions of the present invention have the following beneficial technical effects:

[0030] The recycled ethanol is collected in the telescopic cylinder. The telescopic cylinder descends as the weight of the ethanol increases, thereby driving the lifting plate to descend. When the lifting plate descends, it first drives the first plate to descend, thus stretching the second elastic member. After a relatively large amount of ethanol is collected in the inner cavity of the telescopic cylinder, the first plate is pressed down to the lowest position by the lifting plate, thereby driving the limiting portion to descend, releasing the clamping connection between the concave portion and the limiting portion. At this time, the pulling force of the third elastic member drives the movable portion to move in the direction of the third elastic member, thereby driving the limiting plate to separate from the second plate, causing the second plate to lose its limit and be pulled down by the second elastic member. At this time, the scraping plate is driven to move on the surface of the condenser tube through the first rope, scraping the ink dirt on the surface of the condenser tube, thereby realizing the automatic cleaning of the condenser tube after a long time of ethanol recycling, and preventing the ink dirt from affecting the condensation efficiency of the condenser tube for waste gas;

[0031] And when cleaning the dirt, the third rope is pulled to move by the limiting plate. The third rope drives the first water blocking portion and the second water blocking portion to move in the hollow plate. The upper part of the telescopic cylinder is blocked by the first water blocking portion, and the second water blocking portion moves into the hollow plate. And water is sprayed through the water spraying member, so that the dirt being cleaned is mixed with water and discharged from the water outlet portion, preventing the dirt from mixing with the recycled ethanol.

Detailed implementation manners

[0042] Example 1, as Figures 1-9 shown, an ethanol recovery device for an aqueous ink printing oven proposed by the present invention includes a box body 2, a cleaning mechanism, a locking mechanism, a blocking mechanism, an outer shell 1 and a base 9, and the base 9 is installed in the outer shell 1; further includes:

[0043] A cabinet door and a heat dissipation and dust-proof net are provided on the outer shell 1;

[0044] A condenser 3 and a condensation pipe 4 for condensation are provided in the box body 2, and the condenser 3 and the condensation pipe 4 are connected; Ethanol containing waste gas enters the inner cavity of the box body 2, the condenser 3 and the condensation pipe 4 are started, and the temperature at which ethanol changes from a gas phase to a liquid phase is higher than the temperature at which water vapor changes from a gas phase to a liquid phase. Therefore, the temperature of the condensation pipe 4 is adjusted to a temperature at which ethanol can change from a gas phase to a liquid phase and water vapor will not change from a gas phase to a liquid phase. At this temperature, the ethanol in the inner cavity of the box body 2 becomes liquid, and the water vapor is discharged from the box body 2.

[0045] The cleaning mechanism is arranged in the outer shell 1;

[0046] The locking mechanism is connected to the cleaning mechanism and is used to pull the cleaning mechanism to move;

[0047] The blocking mechanism is connected to the box body 2 and is used to prevent dirt from affecting the recovered ethanol during cleaning;

[0048] The cleaning mechanism includes a collection component, a trigger component, a reset component, a lifting plate 8 and a scraper 15. The collection component is connected to the box body 2 and descends after collecting ethanol. The lifting plate 8 is installed on the collection component and rises and falls with it. The fixed end of the trigger component is connected to the locking mechanism, and its upper end is lifted by the lifting plate 8. The reset component is installed on the box body 2. The reset component is installed on the box body 2. The scraper 15 is sleeved on the condenser tube 4, and both sides of the scraper 15 are respectively connected to the trigger component and the reset component. When the collection component collects ethanol and descends, it pulls the trigger component to descend and store energy and extend. When the collection component descends to the bottom most, it contacts the locking mechanism, and the trigger component is released from the limit of the locking mechanism and contracts and resets, thereby pulling the scraper 15 to clean the condenser tube 4. At this time, the blocking mechanism blocks dirt to avoid pollution.

[0049] The collection component includes a telescopic cylinder 5, a first elastic member 6 and a bottom plate 7.

[0050] The telescopic cylinder 5 is connected to the box body 2. Both ends of the first elastic member 6 are respectively connected to the box body 2 and the bottom plate 7. The bottom plate 7 is installed on the side of the telescopic cylinder 5 away from the box body 2. The telescopic cylinder 5 descends as ethanol is collected. The weight of the ethanol drives the bottom plate 7 to descend, thereby causing the telescopic cylinder 5 to descend, and the first elastic member 6 is stretched as the telescopic cylinder 5 descends.

[0051] The trigger component includes a guide rod 10, a first plate 11, a second elastic member 12 and a second plate 13.

[0052] The guide rod 10 is installed on the locking mechanism.

[0053] Both the first plate 11 and the second plate 13 are sleeved on the guide rod 10. The lifting plate 8 is located between the first plate 11 and the second plate 13, and the second plate 13 is lifted by the lifting plate 8. The bottom plate 7 drives the lifting plate 8 to descend. When the lifting plate 8 descends and contacts the first plate 11, it pulls the first plate 11 to descend. At this time, due to the limit of the locking component on the second plate 13, the second plate 13 does not descend, and the second elastic member 12 is stretched.

[0054] The reset component includes an installation cylinder 17, a torsion spring 18, a rotating shaft, a rope winding disc 19 and a second rope 20.

[0055] The installation cylinder 17 is installed on the box body 2. The torsion spring 18 is installed inside the installation cylinder 17. The rotating shaft is installed at the center of the torsion spring 18. The rope winding disc 19 is connected to the rotating shaft. The second rope 20 is installed inside the rope winding disc 19, and the second rope 20 is connected to the scraper 15. When the scraper 15 moves in the direction of the first rope 14 to clean the condenser tube 4, it pulls the second rope 20 on the rope winding disc 19, thereby driving the rope winding disc 19 to rotate. The rope winding disc 19 drives the rotating shaft to rotate, thereby driving the torsion spring 18 to contract. After the first cleaning is completed, the second plate 13 will rise to slowly reset the first rope 14, and then the torsion spring 18 drives the rope winding disc 19 to rotate in the opposite direction, thereby pulling the second rope 20 to reset, and further pulling the scraper 15 to reset and clean again through the second rope 20.

[0056] The locking mechanism includes a base 9, an elastic member III 21, a movable part 22, a limiting plate 23, a recessed part 24, an elastic member IV 25, a limiting part 26 and a reset unit;

[0057] The base 9 is installed in the housing 1, the guide rod 10 is installed on the base 9, and the elastic member III 21 is connected to the base 9; the movable part 22 is connected to the elastic member III 21; the limiting unit is installed on the movable part 22; the limiting plate 23 is installed on the movable part 22, and the limiting plate 23 is located between the first plate 11 and the second plate 13. In the initial state, there is a gap between the limiting plate 23 and the second plate 13; the recessed part 24 is connected to the movable part 22, the elastic member IV 25 is installed on the base 9, the limiting part 26 is installed on the elastic member IV 25, and the limiting part 26 is snapped into the recessed part 24 to limit the movable part 22; when the lifting plate 8 drives the first plate 11 to start descending, the second plate 13 is blocked by the limiting plate 23 and does not descend. At this time, the elastic member II 12 is stretched. When there is more ethanol in the inner cavity of the telescopic cylinder 5, causing the bottom plate 7 to descend to the lowest end, it drives the first plate 11 to descend to press the limiting part 26, so that the limiting part 26 descends from the groove of the recessed part 24, thereby releasing the connection between the recessed part 24 and the limiting part 26, and the recessed part 24 will continue to press down on the limiting part 26. Then, the elastic member III 21 pulls the movable part 22 in the direction of the elastic member III 21, causing the limiting plate 23 to leave from below the second plate 13, releasing the limit of the second plate 13. After that, the second plate 13 descends under the pulling force of the elastic member II 12, thereby pulling the rope I 14 to drive the scraper 15 to move.

[0058] The reset unit includes a round rod 27 and an inclined plate 41;

[0059] The round rod 27 is installed on the movable part 22, and the inclined plate 41 is installed on the first plate 11; after the ethanol in the box body 2 is completely discharged, the bottom plate 7 is driven to rise by the pulling force of the elastic member I 6, and then the lifting plate 8 drives the second plate 13 and the first plate 11 to rise. The first plate 11 drives the inclined plate 41 to rise, causing the round rod 27 to move along the inclined plate 41, driving the recessed part 24 at the bottom end of the movable part 22 to move, so that the groove of the recessed part 24 returns to the position of the limiting part 26 again, and the limiting part 26 is snapped into the recessed part 24 again, so that the limiting plate 23 is located between the second plate 13 and the first plate 11 for the next use.

[0060] Embodiment 2, as Figures 2-6 and Figure 8 shown, a device for recovering ethanol in a water-based ink printing oven proposed by the present invention. Compared with Embodiment 1, in this embodiment, the blocking mechanism includes a rope III 28, a hollow plate 29, a water-blocking part I 30, a water-blocking part II 31, a water outlet part 40 and a water-blocking component;

[0061] The hollow plate 29 is installed inside the box body 2; the first water blocking part 30 is slidably connected inside the hollow plate 29; the second water blocking part 31 is connected to the first water blocking part 30; the water outlet part 40 communicates with the box body 2, and the hollow plate 29 inclines and extends towards the direction of the water outlet part 40; the water blocking component is installed on the bottom plate 7; in the initial state, the second water blocking part 31 is located at the hollow part of the hollow plate 29 to prevent the ethanol inside the box body 2 from being discharged from the water outlet part 40, and the first water blocking part 30 is located inside the hollow plate 29; during cleaning, the first water blocking part 30 is located at the hollow part of the hollow plate 29 to block the telescopic cylinder 5 and the box body 2, and the second water blocking part 31 is located inside the hollow plate 29, so that the water mixed with ink dirt is discharged from the water outlet part 40.

[0062] There are multiple first water blocking parts 30, and all the multiple first water blocking parts 30 are located inside the box body 2, and the second water blocking part 31 is located inside the water outlet part 40.

[0063] The water blocking component includes a telescopic tube 32, a tube one 34, a tube two 35, an L-shaped plate 36 and a water blocking rod 37;

[0064] The telescopic tube 32 is connected to the bottom plate 7 and communicates with the box body 2; the tube two 35 communicates with the tube one 34; the L-shaped plate 36 is connected to the limiting part 26, the water blocking rod 37 is installed on the L-shaped plate 36, the water blocking rod 37 is located at the connection of the tube one 34 and the tube two 35, and the recycled ethanol cannot be discharged. When the limiting part 26 is pressed downward by the plate one 11 to drive the water blocking rod 37 to descend in the tube one 34, the ethanol in the telescopic cylinder 5 is discharged from the tube two 35, the ethanol in the inner cavity of the telescopic cylinder 5 decreases, the first elastic part 6 pulls the lifting plate 8 to rise, the lifting plate 8 pulls the plate one 11 to rise, and when the plate one 11 rises and separates from the limiting part 26, the limiting part 26 is still blocked by the concave part 24, so the limiting part 26 does not reset until the ethanol in the inner cavity of the telescopic cylinder 5 is emptied.

[0065] Embodiment 3, as Figures 2-4 shown, an ethanol recovery device for an aqueous ink printing oven proposed by the present invention, compared with Embodiment 2, this embodiment further includes a positive and negative electrode ring 38, a positive and negative electrode rod 39, a conveying device 16 and a water spraying part 33;

[0066] The waste gas enters the inner cavity of the box body 2 from one of the conveying devices 16, and then another conveying device 16 is started to discharge the treated waste gas to the next treatment procedure.

[0067] The positive and negative electrode ring 38 is connected to the base 9, the positive and negative electrode rod 39 is installed on the movable part 22, the conveying device 16 communicates with the box body 2, and the water spraying part 33 is installed inside the box body 2; when the movable part 22 is released from the limit to drive the positive and negative electrode rod 39 to be electrically connected to the positive and negative electrode ring 38, the conveying device 16 is triggered to close to prevent new waste gas from entering the inner cavity of the box body 2, and the water spraying part 33 sprays water to assist in cleaning the dirt.

[0068] In the present invention, the first elastic member 6, the third elastic member 21, and the fourth elastic member 25 are all composed of a spring and a telescopic rod.

[0069] In summary, in the present invention, the waste gas generated by the aqueous ink printing oven is connected to a conveying device 16 through a pipeline, and then the pipeline for collecting and treating the waste gas is connected to another conveying device 16. Then, the two conveying devices 16 are started, and the waste gas enters the inner cavity of the box body 2. The condenser 3 and the condensing pipe 4 are started, and the condensing pipe 4 is adjusted to an appropriate temperature. The waste gas contacts the condensing pipe 4, and most of the ethanol in the waste gas changes from the gas phase to the liquid phase and falls into the inner cavity of the telescopic cylinder 5. The treated waste gas is then discharged from the inner cavity of the box body 2 through another conveying device 16.

[0070] As the weight of ethanol in the inner cavity of the telescopic cylinder 5 increases, it drives the bottom plate 7 to descend. The bottom plate 7 drives the lifting plate 8 to descend. The lifting plate 8 contacts the first plate 11 and presses down the first plate 11. At this time, since the second plate 13 is limited by the limiting plate 23, the second plate 13 will not descend. Therefore, when the first plate 11 descends, the second elastic member 12 is stretched.

[0071] When the first plate 11 descends to the lowest end, it presses the limiting portion 26 to descend, thereby releasing the limitation between the concave portion 24 and the limiting portion 26, and the movable portion 22 loses its limitation. At this time, the pulling force of the third elastic member 21 drives the movable portion 22 to move in the direction of the third elastic member 21, so that the limiting plate 23 leaves from below the second plate 13. After the second plate 13 loses the limitation of the limiting plate 23, the pulling force of the second elastic member 12 drives the second plate 13 to descend. The second plate 13 descends and pulls the first rope 14 to move. The first rope 14 pulls the scraping plate 15 to move on the surface of the condensing pipe 4, thereby scraping off the ink dirt on the surface of the condensing pipe 4. Thus, after a long time of ethanol recovery, the condensing pipe 4 is automatically cleaned, avoiding the influence of dirt on the condensing efficiency of the condensing pipe 4 for waste gas;

[0072] When the telescopic cylinder 5 moves in the direction of the first rope 14, it will pull the second rope 20 to move, thereby driving the rope winding disc 19 to rotate. The rotation of the rope winding disc 19 drives the spiral spring 18 to contract and store energy.

[0073] When the movable portion 22 moves in the direction of the third elastic member 21, it drives the positive and negative pole rod 39 and the positive and negative pole ring 38 to be connected, sending a signal to an external control device to close the conveying device 16 to prevent new waste gas from entering, and to start the water spraying member 33 to spray water;

[0074] Meanwhile, the movable part 22 drives the water blocking part one 30 and the water blocking part two 31 to move by pulling the rope three 28, so that the water blocking part one 30 moves to the hollow part of the hollow plate 29, and the water blocking part two 31 moves to the inner cavity of the hollow plate 29, so that the water blocking part one 30 blocks the box body 2 and the telescopic cylinder 5. Then, the water sprayed by the water spraying part 33 is mixed with the dirt cleaned by the scraping plate 15 and discharged from the water outlet part 40, avoiding the situation that the dirt after the scraping plate 15 cleans the condensing pipe 4 falls into the ethanol, resulting in the pollution of the ethanol by the dirt.

[0075] When the limiting part 26 descends, it will drive the L-shaped plate 36 to descend. The L-shaped plate 36 drives the water blocking rod 37 to descend in the inner cavity of the pipe one 34, so that the ethanol in the inner cavity of the telescopic cylinder 5 is discharged from the pipe two 35 through the telescopic pipe 32. The ethanol in the inner cavity of the telescopic cylinder 5 decreases, so that the bottom plate 7 is driven by the pulling force of the elastic part one 6 to rise and reset. During the reset process, since the concave part 24 will continue to press the limiting part 26, the L-shaped plate 36 will not reset at this time.

[0076] At this time, the elastic force of the torsion spring 18 drives the rope winding disc 19 to rotate in the reverse direction and contract the rope two 20. Then, the scraping plate 15 is pulled by the rope two 20 to move in the direction of the rope two 20 to clean the condensing pipe 4 again.

[0077] When the lifting plate 8 rises, the lifting plate 8 separates from the plate one 11 and instead contacts the bottom of the plate two 13, and then lifts the plate two 13 upward. At this time, the plate two 13 pulls the plate one 11 to rise through the elastic part two 12. When the plate two 13 passes over the limiting plate 23, the plate one 11 also rises to a high position. The plate one 11 drives the inclined plate 41 to contact the round rod 27, so that the round rod 27 moves along the inclined plate 41, thereby pulling the movable part 22 in the direction of the plate one 11, and further making the groove of the concave part 24 at the bottom of the movable part 22 engage with the limiting part 26 again. The limiting plate 23 returns below the plate two 13, and the movable part 22 drives the positive and negative electrode rings 38 and the positive and negative electrode rods 39 to separate. The conveying device 16 is turned on and the water spraying part 33 is turned off;

[0078] And because the hollow plate 29 is inclined towards the water outlet part 40, the water blocking part one 30 and the water blocking part two 31 slide and reset in the inner cavity of the hollow plate 29 by their own gravity.

[0079] The embodiments of the present invention have been described in detail above with reference to the drawings. However, the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the knowledge scope of those skilled in the art.
