Description

Technical Field

[0001] The invention relates to the technical field of ethanol recovery, and in particular to an ethanol recovery device for a water-based ink printing oven. Background Art

[0002] In the water-based ink printing process, the printed product needs to be dried by heating in an oven. Although the ethanol added during the ink manufacturing can improve the drying efficiency, it causes the baking exhaust gas to contain ethanol components, which cannot be discharged directly. Therefore, an ethanol recovery device is required to realize the resource recovery of ethanol in the exhaust gas.

[0003] The Chinese invention application with the publication number CN107297125A discloses an ethanol recovery device for a water-based ink printing oven, comprising a sealed container having a mixed air cavity and a mixed gas-liquid mixing cavity; the mixed air cavity has an air intake duct for communicating with the exhaust gas of the water-based ink printing oven. The above-mentioned prior art uses the good miscibility of water and ethanol to achieve the purpose of recovering ethanol in the exhaust gas of the oven through gas-liquid mixing, which is economical, energy-saving and operable, but this will result in the need to use a large amount of water, resulting in a waste of water resources; In the prior art, the temperature of the condensation unit is set within a suitable range, taking advantage of the fact that the temperature required for ethanol in the waste gas to become liquid is higher than that of water vapor, so that the ethanol in the waste gas is converted into a liquid phase, while the water vapor remains in a gas phase, thereby recovering a large amount of ethanol. Subsequently, the remaining waste gas is treated with the help of activated carbon fibers to further recover ethanol, thereby completing the ethanol recovery process. However, the composition of the waste gas is complex, and in addition to water vapor and ethanol, it also contains some ink impurities. These impurities will adhere to the condensation tube of the condensation unit with the waste gas, causing a large amount of dirt to form on the condensation tube, thereby affecting the normal operation of the condensation unit, reducing the ethanol recovery efficiency and the service life of the equipment.

After the first cleaning is completed, the plate 2 13 will rise, causing the rope 14 to slowly reset, and then the coil spring 18 drives the rope collecting drum 19 to rotate in the opposite direction, thereby pulling the rope 20 to reset, and then pulling the scraper 15 through the rope 20 to reset and clean again.

[0022] The locking mechanism includes a base 9, an elastic member 3 21, a movable portion 22, a limit plate 23, a recessed portion 24, an elastic member 4 25, a limit portion 26 and a reset unit; The base 9 is installed in the housing 1, the guide rod 10 is installed on the base 9, the elastic member 3 21 is connected to the base 9; the movable part 22 is connected to the elastic member 3 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 plate 1 11 and the plate 2 13.

When there is more ethanol in the inner cavity of the telescopic cylinder 5, the bottom plate 7 is lowered to the bottom, driving the plate 1 11 to descend to press the limit portion 26, so that the limit portion 26 descends from the groove of the recessed portion 24, and then the recessed portion 24 and the limit portion 26 are released, and the recessed portion 24 will continue to press down on the limit portion 26, and then the elastic member 3 21 pulls the movable portion 22 in the direction of the elastic member 3 21, so that the limit plate 23 leaves from the bottom of the plate 2 13, releasing the limit of the plate 2 13, and then the plate 2 13 descends through the pulling force of the elastic member 2 12, thereby pulling the rope 14 to drive the scraper 15 to move.

[0023] The reset unit includes a round rod 27 and an inclined plate 41; The round rod 27 is installed on the movable part 22, and the inclined plate 41 is installed on the plate 11; after the ethanol in the box body 2 is discharged, the bottom plate 7 is driven to rise by the pulling force of the elastic member 6, so that the lifting plate 8 pulls the plate 2 13 and the plate 1 11 to rise, and the plate 1 11 drives the inclined plate 41 to rise so that the round rod 27 moves 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 limit part 26, so that the limit part 26 is re-stuck in the recessed part 24, so that the limit plate 23 is located between the plate 2 13 and the plate 1 11 for the next use.

[0024] Embodiment 2, as Figure 2-Figure 6 and Figure 8 As shown, the ethanol recovery device of the water-based ink printing oven proposed by the present invention, compared with the first embodiment, the blocking mechanism in this embodiment includes a rope three 28, a hollow plate 29, a water retaining part 1 30, a water retaining part 2 31, a water outlet 40 and a water blocking component; The hollow plate 29 is installed in the box body 2; the water retaining part 30 is slidably connected in the hollow plate 29; the water retaining part 2 31 is connected to the water retaining part 1 30; the water outlet 40 is connected to the box body 2, and the hollow plate 29 is inclined and extended in the direction of the water outlet 40; the water blocking assembly is installed on the bottom plate 7; in the initial state, the water retaining part 2 31 is located at the hollow part of the hollow plate 29 to prevent the ethanol in the box body 2 from being discharged from the water outlet 40, and the water retaining part 1 30 is located in the hollow plate 29; when cleaning, the water retaining part 1 30 is located at the hollow part of the hollow plate 29 to block the telescopic tube 5 and the box body 2, and the water retaining part 2 31 is located inside the hollow plate 29, so that water mixed with ink and dirt is discharged from the water outlet 40.

[0025] There are multiple water retaining parts 1 30 , and the multiple water retaining parts 1 30 are all located in the box body 2 , and the water retaining part 2 31 is located in the water outlet part 40 .

[0026] The water blocking assembly includes a telescopic pipe 32, a pipe 1 34, a pipe 2 35, an L-shaped plate 36 and a water blocking rod 37; The telescopic tube 32 is connected to the bottom plate 7 and is connected to the box body 2; the tube 2 35 is connected to the tube 1 34; the L-shaped plate 36 is connected to the limiting portion 26, and the water blocking rod 37 is installed on the L-shaped plate 36. The water blocking rod 37 is located at the connection between the tube 1 34 and the tube 2 35, and the recovered ethanol cannot be discharged. When the limiting portion 26 is pressed downward by the plate 11 to drive the water blocking rod 37 to descend in the tube 1 34, the ethanol in the telescopic cylinder 5 is discharged from the tube 2 35, and the ethanol in the inner cavity of the telescopic cylinder 5 is reduced. The elastic member 16 pulls the lifting plate 8 to rise, and the lifting plate 8 pulls the plate 11 to rise. When the plate 11 rises and separates from the limiting portion 26, the limiting portion 26 continues to be blocked by the recessed portion 24, so the limiting portion 26 is not reset until the ethanol in the inner cavity of the telescopic cylinder 5 is emptied.

[0027] Embodiment three, as Figure 2-Figure 4As shown, the ethanol recovery device of the water-based ink printing oven proposed by the present invention, compared with the second embodiment, this embodiment also includes positive and negative electrode rings 38, positive and negative electrode rods 39, a conveying device 16 and a water spraying member 33; The waste gas enters the inner cavity of the box body 2 from one of the conveying devices 16, and then the other conveying device 16 is started to discharge the treated waste gas to the next treatment procedure.

[0028] The positive and negative electrode rings 38 are connected to the base 9, the positive and negative electrode rods 39 are installed on the movable part 22, the conveying device 16 is connected to the box body 2, and the water spray component 33 is installed in the box body 2; the movable part 22 releases the limit to drive the positive and negative electrode rods 39 to be electrically connected with the positive and negative electrode rings 38, triggering the conveying device 16 to close, preventing new exhaust gas from entering the inner cavity of the box body 2, and the water spray component 33 sprays water to assist in cleaning dirt.

[0029] The elastic member 1 6, the elastic member 3 21 and the elastic member 4 25 in the present invention are all composed of a spring and a telescopic rod.

[0030] In summary, in the present invention, the waste gas generated by the water-based ink printing oven is connected to a conveying device 16 through a pipe, and then the pipe for collecting the treated waste gas is connected to another conveying device 16, and then the two conveying devices 16 are started, the waste gas enters the inner cavity of the box 2, and the condenser 3 and the condenser 4 are started, the condenser 4 is adjusted to a suitable temperature, the waste gas contacts the condenser 4, and most of the ethanol in the waste gas changes from gas phase to liquid phase and falls into the inner cavity of the telescopic cylinder 5, and the treated waste gas is discharged from the inner cavity of the box 2 from another conveying device 16.

[0031] As the weight of ethanol in the inner cavity of the telescopic cylinder 5 increases, the bottom plate 7 is driven to descend, and the bottom plate 7 drives the lifting plate 8 to descend. The lifting plate 8 contacts the plate 11 and presses the plate 11 downward. At this time, since the plate 2 13 is limited by the limiting plate 23, the plate 2 13 will not descend. Therefore, the plate 11 descends to stretch the elastic member 2 12.

[0032] When the plate 11 drops to the bottom, the limit part 26 is pressed down, thereby releasing the limit of the recessed part 24 and the limit part 26, so that the movable part 22 loses the limit. At this time, the movable part 22 is driven to move in the direction of the elastic part 3 21 by the pulling force of the elastic part 3 21, so that the limit plate 23 leaves from the bottom of the plate 2 13. After the plate 2 13 loses the limit of the limit plate 23, the plate 2 13 is driven down by the pulling force of the elastic part 2 12. The plate 2 13 drops and pulls the rope 14 to move. The rope 14 pulls the scraper 15 to move on the surface of the condenser 4, so as to scrape off the ink dirt on the surface of the condenser 4, thereby realizing the automatic cleaning of the condenser 4 after a long period of ethanol recovery, and preventing the dirt from affecting the condensation efficiency of the condenser 4 for the exhaust gas. When the telescopic cylinder 5 moves in the direction of the rope 1 14, it will pull the rope 2 20 to move, thereby driving the rope collecting drum 19 to rotate, and the rotation of the rope collecting drum 19 drives the winding spring 18 to contract and store force.

[0033] When the movable part 22 moves toward the direction of the elastic part 3 21, it drives the positive and negative poles 39 to connect with the positive and negative pole rings 38, sends a signal to the external control device, closes the conveying device 16 to prevent new exhaust gas from entering, and starts the water spraying part 33 to spray water; At the same time, the movable part 22 pulls the water retaining part 1 30 and the water retaining part 2 31 to move through the rope 3 28, so that the water retaining part 1 30 moves to the hollow part of the hollow plate 29, and the water retaining part 2 31 moves to the inner cavity of the hollow plate 29, so that the water retaining part 1 30 blocks the box body 2 and the telescopic cylinder 5, and then the water sprayed by the water spraying part 33 is mixed with the dirt cleaned by the scraper 15 and discharged from the water outlet 40, thereby avoiding the dirt after the scraper 15 cleans the condenser 4 falling into the ethanol, causing the ethanol to be contaminated by the dirt.

[0034] When the limiting portion 26 descends, the L-shaped plate 36 is driven downward, and the L-shaped plate 36 drives the water blocking rod 37 to descend in the inner cavity of the tube 1 34, so that the ethanol in the inner cavity of the telescopic cylinder 5 is discharged from the tube 2 35 through the telescopic tube 32. The ethanol in the inner cavity of the telescopic cylinder 5 is reduced, and the bottom plate 7 is driven to rise and reset through the pulling force of the elastic member 1 6. During the resetting process, since the recessed portion 24 will continue to press the limiting portion 26, the L-shaped plate 36 will not reset at this time.

[0035] At this time, the elasticity of the coil spring 18 drives the rope collecting disc 19 to rotate in the opposite direction to retract the rope 20, and then the rope 20 pulls the scraper 15 to move in the direction of the rope 20 to clean the condenser tube 4 again.

[0036] When the lifting plate 8 rises, the lifting plate 8 separates from the plate 11 and contacts the bottom of the plate 2 13, thereby lifting the plate 2 13 upward. At this time, the plate 2 13 pulls the plate 11 up through the elastic member 2 12. After the plate 2 13 passes over the limiting plate 23, the plate 11 also rises to a high place. The plate 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 toward the plate 11, thereby making the groove of the recessed part 24 at the bottom of the movable part 22 re-engage with the limiting part 26, and the limiting plate 23 returns to the bottom of the plate 2 13. 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 member 33 is closed; And because the hollow plate 29 is inclined toward the water outlet 40 , the water retaining portion 1 30 and the water retaining portion 2 31 are slid and reset in the inner cavity of the hollow plate 29 by their own gravity.

[0037] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
