Description

Technical Field

[0001] The present invention relates to the technical field of gas processing equipment, and in particular to an environmentally friendly packaging and printing VOC processing equipment. Background Art

[0002] The inks and solvents used in the printing process contain a large amount of volatile organic compounds (VOCs for short). Most VOCs are toxic and carcinogenic to a certain extent. In order to prevent direct emissions that may harm the human body and the environment, most printing workshops are currently equipped with exhaust gas VOC treatment equipment. Commonly used VOC treatment methods are activated carbon adsorption, photocatalytic decomposition, and catalytic combustion. The photocatalytic principle is based on the redox ability of photocatalysts under light conditions. Normally, photocatalytic oxidation reactions use semiconductors as catalysts and light as energy to degrade organic matter into carbon dioxide and water. To ensure the treatment effect, a composite method is usually used for comprehensive treatment.

[0003] When photocatalytically treating VOCs generated in a printing workshop, it is necessary to first pass the workshop exhaust gas mixed with particulate matter and VOCs into an activated carbon adsorption bed. After preliminary adsorption and purification of the exhaust gas, it is then passed into a photocatalytic reaction device for degradation. The activated carbon bag in the activated carbon adsorption bed needs to be replaced regularly. Currently, most activated carbon replacement methods are still manual. During the replacement process, residual exhaust gas in the activated carbon adsorption bed and the front and rear gas pipes is prone to leakage. For this reason, an environmentally friendly packaging and printing VOC treatment equipment is proposed. Summary of the invention

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. The present invention sets modular filter plates, so that after long-term use of the modular filter plates, the adsorption performance of the activated carbon particles inside the modular filter plates is significantly reduced. At this time, the exhaust gas delivery is stopped, so that the modular filter plates are automatically replaced. When the modular filter plates inside the plate changing box are exhausted or insufficient, the staff can open the replacement magnetic suction door, insert a batch of modular filter plates into the replacement jacks in turn, and make the carrying rack alternately push the new modular filter plates into the innermost side of the plate changing box one by one, so as to realize the rapid replenishment of the modular filter plates. The staff only needs to replenish the modular filter plates in time, thereby reducing the occurrence of exhaust gas leakage;

[0018] 2. The present invention provides a vertical flip rail so that the vertical flip rail can store the modular filter plate inside under normal conditions, thereby positioning the modular filter plate. When replacing the modular filter plate, the vertical flip rail can be rotated to both sides to provide a moving track for replacing the modular filter plate, thereby ensuring that the modular filter plate is stable during movement.

[0019] 3. The present invention provides a positioning slide and a replacement slide, so that when the modular filter plate is added to the plate changing box, the positioning slider on the modular filter plate will slide in the positioning slide, so as to position the modular filter plate. When the modular filter plate is pushed out of the plate changing box by the push plate, the modular filter plate slides out of the passage jack, and the positioning slider moves along the replacement slide on the other side to complete the docking between the internal track of the plate changing box and the horizontal fixed slide rail, so as to prevent the modular filter plate from being misplaced or offset during the replacement process.

[0020] 4. The present invention provides an electric sliding door so that before replacing the modular filter plate, the driving slide rail drives the internal electric sliding door to slide downward until the electric sliding door is fully inserted into the sealed door frame, sealing one end of the two adsorption tubes, disconnecting the two adsorption tubes from the air intake pipe and the air delivery pipe, and preventing the residual exhaust gas in the air delivery pipe from leaking through the unfolded air filter assembly into the plate replacement box, the plate collection box or the photocatalytic purification device, or directly leaking into the external environment;

[0021] 5. The present invention provides an air pump so that after the electric sliding door closes the adsorption tube, the air pump is started to extract the residual waste gas in the adsorption tube and the air filter assembly into the air storage box through the air pump for temporary storage, thereby reducing the leakage of the residual waste gas in the adsorption tube and the air filter assembly when the modular filter plate is replaced. When the modular filter plate is replaced, the air supply inside the adsorption tube is restored, and the waste gas in the air storage box flows back to the air filter assembly under the action of air pressure for further treatment;

[0022] 6. The present invention provides a sealed shell so that the sealed shell accommodates the entire air filter assembly inside, and the access holes on the plate changing box and the plate receiving box are also located inside the sealed shell, so that the replacement of the entire modular filter plate is carried out in the sealed space inside the sealed shell. Even if some exhaust gas leaks from the inside of the adsorption tube, it will not continue to leak to the external environment, and will then flow back into the adsorption tube under the suction of the vacuum pump;

[0023] 7. The present invention provides a sealed electric push rod and a sealed slide plate, so that when the modular adsorption plate is replaced, the vertical flip rail is reset, and the sealed electric push rod drives the sealed slide plate to slide down, so that the sealed slide plate slides to the junction of the two vertical flip rails, so that the gap between the two vertical flip rails is covered by the sealed slide plate, thereby improving the sealing performance of the overall frame of the horizontal fixed rail and the vertical flip rail, and reducing the leakage of exhaust gas;

[0024] 8. The present invention provides a sealing elastic strip so that after the vertical flip rail is rotated and reset, it will be stuck between the front and rear sealing elastic strips, and the sealing elastic strips on both sides are deformed by squeezing, thereby improving the sealing performance of the joint between the vertical flip rail and the adsorption tube. At the same time, after the vertical flip rail is reset, the two sides of the sealing slide plate will also contact the sealing elastic strip, so that the sealing slide plate and the sealing elastic strip jointly cover the gap between the two vertical flip rails, thereby improving the sealing performance between the two vertical flip rails;

[0025] 9. The present invention provides an assembly ring so that when recycling the old modular adsorption board in the board collection box, the assembly ring on the reinforcement frame and the second filter screen can be removed together, and then the activated carbon particles inside the adsorption frame can be poured out for purification or directly replaced, and then the assembly ring can be assembled on the reinforcement frame, so that the modular adsorption board has sufficient adsorption performance again, so as to be put into use again;

[0026] 10. The present invention sets positioning elastic pins so that when a new modular adsorption plate is pushed into the interior of the horizontal fixed slide rail by the push plate, multiple positioning elastic pins will be respectively inserted into multiple positioning slots, so that the positioning elastic pins and the positioning slots can perform preliminary positioning on the modular adsorption plate, thereby preventing the modular adsorption plate from excessively moving under the action of inertia, causing the modular adsorption plate to be misaligned with the frame where the horizontal fixed slide rail and the vertical flip slide rail are located, thereby affecting the subsequent resetting of the vertical flip slide rail.

[0043] The air filter assembly is used to absorb and filter the exhaust gas from the printing workshop before photocatalytic treatment, such as Figure 3 As shown, the air filter assembly includes two adsorption tubes 4 arranged between the air inlet pipe 2 and the air delivery pipe 3. Figure 4 As shown, two horizontal fixed slide rails 5 are fixedly installed between the two adsorption tubes 4.

The same modular adsorption plate is arranged between the two horizontal fixed slide rails 5 and the four vertical flip slide rails 7. The modular adsorption plate includes an adsorption frame 10 that is slidably inserted between the two horizontal fixed slide rails 5 and the four vertical flip slide rails 7. Figure 7 As shown, a plurality of evenly distributed positioning sliders 11 are fixedly installed on the top and bottom of the adsorption frame 10, two vertically arranged reinforcing frames 12 are fixedly installed inside the adsorption frame 10, and a plurality of first filter screens 13 are fixedly installed inside the reinforcing frames 12. In this embodiment, a large amount of activated carbon particles are loaded between the reinforcing frames 12 and the first filter screens 13 on both sides;

[0044] like Figure 1 As shown, a plate changing box 14 for loading modular adsorption plates and a plate collecting box 15 for recovering modular adsorption plates are provided on one side of the photocatalytic purification device 1. The plate changing box 14 and the plate collecting box 15 are distributed on both sides of the air filter assembly. Figure 8As shown, the plate changing box 14 and the plate collecting box 15 are both provided with a passage hole 16 on the side facing the air filter assembly, and the passage hole 16 is consistent with the position of the vertical flip slide rail 7. In this embodiment, the interior of the plate collecting box 15 is provided with unloading claws, an electric slide, a conveying device such as a conveyor belt, which is used to separate or transport the old modular adsorption plates to be replaced to other areas to prevent the modular adsorption plates from piling up at the passage hole 16 of the plate collecting box 15, affecting the subsequent resetting of the vertical flip slide rail 7 and the recovery of the modular adsorption plates. The plate changing box 14 and the plate collecting box 15 are both fixedly installed with a support rail 17 on the side facing the air filter assembly. The two support rails 17 are respectively located below the two passage holes 16, and the support rails 17 are adapted to the vertical flip slide rail 7. Fig. 9 As shown, the top and bottom of the plate changing box 14 are provided with a plurality of positioning slots 1401 adapted to the positioning slide block 11, and a push box 18 is fixedly installed on the side of the plate changing box 14 away from the air filter assembly, and the push box 18 is connected to the interior of the plate changing box 14, as shown in FIG. Fig.10 As shown, a horizontally arranged propulsion guide rail 19 is fixedly installed inside the propulsion box 18, a propulsion electric slide 20 is driven and installed on the top of the propulsion electric slide 20, a propulsion frame 21 is fixedly installed on the top of the propulsion electric slide 20, and the propulsion frame 21 is slidably installed inside the propulsion box 18, one end of the propulsion frame 21 faces the plate changing box 14 and is fixedly installed with a propulsion plate 22 adapted to the passage socket 16, as shown in FIG. Fig. 9 As shown, a carry box 23 is fixedly installed on the top of the plate changing box 14, and the carry box 23 is connected to the inside of the plate changing box 14. A horizontally arranged carry rail is fixedly installed inside the carry rail, and a carry electric slide 24 is driven and installed at the bottom of the carry guide rail. A carry frame 25 is fixedly installed at the bottom of the carry electric slide 24. A replacement socket 1402 is opened on the side of the plate changing box 14 away from the air filter assembly, as shown in FIG. Figure 2As shown, a replacement magnetic suction door 26 is rotatably installed on one side of the plate changing box 14, and the replacement magnetic suction door 26 corresponds to the position of the replacement socket 1402. Two replacement slides compatible with the positioning slider 11 are provided on the top and bottom inner walls of the plate changing box 14. The four replacement slides located on both sides are respectively connected to the replacement socket 1402 and the passage socket 16. A maintenance door 27 is rotatably installed on one side of the plate changing box 14; specifically, when the environmentally friendly packaging and printing VOC treatment equipment is in use, the gas supply pipe 3 is connected to the waste gas extraction equipment of the printing workshop, so that the waste gas of the transport workshop passes through the gas supply pipe 3 through the filter assembly, and is adsorbed and filtered by the internal modular filter plate, and then transmitted to the photocatalytic purification equipment 1 through the air intake pipe 2 for photocatalytic reaction purification, and finally the VOC substances are removed. The purified exhaust gas is discharged to complete the VOC treatment of the exhaust gas. By setting up a modular filter plate, the adsorption performance of the activated carbon particles inside the modular filter plate is significantly reduced after long-term use. At this time, the transportation of the exhaust gas is stopped, and each flip motor 9 drives the rotating shaft 6 to rotate, driving a total of four vertical flip slide rails 7 on both sides to flip from a vertical state to a horizontal state. The two vertical flip slide rails 7 located at the bottom will contact the support rails 17 on both sides respectively and be supported by the support rails 17. Then the propulsion electric slide 20 inside the propulsion box 18 slides along the propulsion guide rail 19, and drives the propulsion plate 22 to enter the plate changing box 14 through the propulsion frame 21 and contact the new modular filter plate at the innermost side of the plate changing box 14, and push the modular filter plate toward the air filter assembly. The new modular filter plate is made to slide between the two vertical flip rails 7 on one side until the new modular filter plate contacts the old modular filter plate between the two horizontal fixed rails 5, so that it is pushed to the inside of the plate receiving box 15 through the vertical flip rail 7 on the other side, and then transported to other areas by the conveying device inside the plate receiving box 15, so that the old modular filter plate is separated from the vertical flip rail 7, and then the pushing plate 22 is retracted into the inside of the pushing box 18, and the flip motor 9 drives the vertical flip rails 7 on both sides to reset, so that the upper and lower horizontal fixed rails 5 and the four vertical flip rails 7 on both sides are merged on the surrounding side of the new modular filter plate, completing the replacement of the modular filter plate, and finally, the carrying electric slide 24 inside the plate changing box 14 drives the carrying rack 25 By moving along the carry guide rail, the carry rack 25 pushes all the modular filter panels inside the panel change box 14 toward the position of the access socket 16 for a unit distance, so that the empty positions of the modular filter panels are filled, so as to facilitate the subsequent replacement of the modular filter panels. When the modular filter panels inside the panel change box 14 are used up or insufficient in number, the staff can open the replacement magnetic suction door 26 and insert a batch of modular filter panels into the replacement socket 1402 in turn, so that the carry rack 25 alternately pushes the new modular filter panels one by one into the innermost side of the panel change box 14, so as to realize the rapid replenishment of the modular filter panels and automatically replace the modular filter panels. The staff only needs to replenish the modular filter panels in time, thereby reducing the occurrence of exhaust gas leakage. By setting the vertical flip slide rail 7,Under normal circumstances, the vertical flip slide rail 7 can store the modular filter plate inside, which plays a role in positioning the modular filter plate. When replacing the modular filter plate, the vertical flip slide rail 7 can be rotated to both sides to provide a moving track for the replacement of the modular filter plate, thereby ensuring that the modular filter plate is stable during movement. By setting the positioning slide groove 1401 and the replacement slide groove, when the modular filter plate is added to the plate changing box 14, the modular filter plate passes through the replacement socket 1402, and the top and bottom positioning sliders 11 thereof will slide in the replacement slide groove until the modular filter plate is completely entered into the plate changing box 14 and is in the plate changing box. 14, and then the carrying frame 25 pushes the modular filter plate to slide in the plate changing box 14, and the positioning slider 11 on the modular filter plate will also slide in the positioning slide groove 1401, which plays a role in positioning the modular filter plate. When the modular filter plate is pushed out of the plate changing box 14 by the pushing plate 22, the modular filter plate slides out of the passage socket 16, and the positioning slider 11 moves along the replacement slide groove on the other side until the modular filter plate moves to the vertical flip slide rail 7, completing the docking of the internal track of the plate changing box 14 and the horizontal fixed slide rail 5, preventing the modular filter plate from being misplaced or offset during the replacement process.

[0045] like Figure 3 As shown, the ends of the two adsorption tubes 4 away from each other are fixedly installed with sealing door frames 28, and the two sealing door frames 28 are respectively fixedly installed on one end of the air intake pipe 2 and the air supply pipe 3, and the top of the sealing door frame 28 is fixedly installed with a driving slide rail 29 connected to the sealing door frame 28, and the inside of the driving slide rail 29 is driven to install an electric sliding door 30, and the electric sliding door 30 is adapted to the sealing door frame 28; specifically, by setting the electric sliding door 30, before replacing the modular filter plate, the driving slide rail 29 will drive the internal electric sliding door 30 to slide downward until the electric sliding door 30 is completely inserted into the sealing door frame 28, closing one end of the two adsorption tubes 4, so that the connection between the two adsorption tubes 4 and the air intake pipe 2 and the air supply pipe 3 is disconnected, preventing the residual exhaust gas in the air supply pipe 3 from leaking into the plate changing box 14, the plate collecting box 15 or the photocatalytic purification equipment 1 through the unfolded air filter assembly, or directly leaking into the external environment.

[0046] like Figure 3As shown, the same air pump 31 is fixedly installed on the top of the two adsorption tubes 4, and the air inlet end of the air pump 31 is fixedly installed with an air suction pipe 32, one end of the air suction pipe 32 extends to the inside of one of the adsorption tubes 4, and the same air storage box 33 is fixedly installed between the two driving slide rails 29, and the exhaust end of the air pump 31 is connected to the inside of the air storage box 33. In this embodiment, the inside of the air storage box 33 is provided with an elastic air bag and an electromagnetic control valve for storing the residual exhaust gas extracted by the air pump 31, and a counterflow pipe is provided between the air storage box 33 and the adsorption tube 4, and the counterflow pipe is also provided with an electromagnetic control valve. After the replacement is completed, the exhaust gas temporarily stored in the air storage box 33 can flow back to the adsorption tube 4 through the countercurrent pipe for continued filtering; specifically, by setting the vacuum pump 31, after the electric sliding door 30 closes the adsorption tube 4, the vacuum pump 31 is started, and the residual exhaust gas in the adsorption tube 4 and the air filter assembly is extracted into the air storage box 33 through the vacuum pipe 32 for temporary storage, thereby reducing the leakage of residual exhaust gas in the adsorption tube 4 and the air filter assembly when replacing the modular filter plate. When the modular filter plate is replaced, the air supply is restored inside the adsorption tube 4, and the exhaust gas in the air storage box 33 flows back to the air filter assembly under the action of air pressure for continued processing.

[0047] like Figure 1 As shown, a same sealed shell 34 is fixedly installed between the plate changing box 14 and the plate collecting box 15, and the sealed shell 34 is fixedly sleeved on the air inlet pipe 2 and the air delivery pipe 3, and the intake box 23, the air storage box 33 and the air filter assembly are all located inside the sealed shell 34; specifically, by setting the sealed shell 34, the sealed shell 34 accommodates the entire air filter assembly inside, and at the same time, the pass sockets 16 on the plate changing box 14 and the plate collecting box 15 are also located inside the sealed shell 34, so that the replacement of the entire modular filter plate is carried out in the sealed space inside the sealed shell 34, even if some exhaust gas leaks from the inside of the adsorption tube 4, it will not continue to leak to the external environment, and will then flow back into the adsorption tube 4 under the suction of the vacuum pump 31.

[0048] like Figure 5As shown, one side of the two vertical flip slide rails 7 located at the top is fixedly installed with a vertically arranged sealed electric push rod 35, and the telescopic end of the sealed electric push rod 35 is fixedly installed with a sealing slide plate 36, and the sealing slide plate 36 is slidably installed on the vertical flip slide rail 7; specifically, by arranging the sealed electric push rod 35 and the sealing slide plate 36, before the vertical flip slide rail 7 flips, the sealed electric push rod 35 drives the sealing slide plate 36 to slide upward and disengage from the vertical flip slide rail 7 below, so that the two vertical flip slide rails 7 can be smoothly unfolded. When the modular adsorption plate is replaced, the vertical flip slide rail 7 is reset, and the sealed electric push rod 35 will drive the sealing slide plate 36 to slide down, so that the sealing slide plate 36 slides to the junction of the two vertical flip slide rails 7, so that the gap between the two vertical flip slide rails 7 is covered by the sealing slide plate 36, thereby improving the sealing of the overall frame of the horizontal fixed slide rail 5 and the vertical flip slide rail 7, and reducing the leakage of exhaust gas.

[0049] like Figure 4 As shown, two sealing elastic strips 37 are fixedly installed at one end of the two adsorption tubes 4 that are close to each other, and the two sealing elastic strips 37 located on the same side are respectively in contact with the two sides of the vertical flip slide 7, and the two sealing elastic strips 37 located on the same side are respectively in contact with the two side edges of the sealing slide plate 36. In this embodiment, a clearance groove for the sealing slide plate 36 to move is opened on one side of the sealing elastic strip 37; specifically, by setting the sealing elastic strip 37, after the vertical flip slide 7 is rotated and reset, it will be stuck between the front and rear two sealing elastic strips 37, and the sealing elastic strips 37 on both sides are deformed by extrusion, thereby improving the sealing of the joint between the vertical flip slide 7 and the adsorption tube 4. At the same time, after the vertical flip slide 7 is reset, the two sides of the sealing slide plate 36 will also contact the sealing elastic strip 37, so that the sealing slide plate 36 and the sealing elastic strip 37 jointly cover the gap between the two vertical flip slide rails 7, thereby improving the sealing between the two vertical flip slide rails 7.

[0050] like Figure 7 As shown, an assembly ring 38 is fixedly installed on one of the reinforcement frames 12, and a second filter screen 39 is fixedly installed inside the assembly ring 38. In the present embodiment, a circular gap is provided on one of the reinforcement frames 12 of the same modular adsorption plate, and on one side of the gap, the reinforcement frame 12 is installed with the assembly ring 38 by fastening bolts; specifically, by providing the assembly ring 38, when the old modular adsorption plate in the collecting box 15 is recovered, the assembly ring 38 and the second filter screen 39 on the reinforcement frame 12 can be removed together, and then the activated carbon particles inside the adsorption frame 10 can be poured out for purification or directly replaced, and then the assembly ring 38 can be assembled on the reinforcement frame 12, so that the modular adsorption plate can regain sufficient adsorption performance to be put into use again.

[0051] like Figure 6As shown, positioning plates 40 are fixedly installed on both sides of the horizontal fixed slide rail 5, and positioning elastic pins 41 are fixedly installed on the side of the positioning plate 40 facing the adsorption frame 10. Positioning slots 1001 compatible with the positioning elastic pins 41 are opened on both sides of the top and bottom of the adsorption frame 10. In this embodiment, the positioning elastic pin 41 can be an elastic pin composed of an outer cylinder, a spring and a round-headed slide rod, which is convenient for frequent plug-in and positioning; specifically, by setting the positioning elastic pin 41, when the new modular adsorption plate is pushed into the horizontal fixed slide rail 5 by the push plate 22, the adsorption frame 10 will first contact the positioning elastic pin 41 and shrink the positioning elastic pin 41 until a plurality of positioning elastic pins 41 are respectively inserted into a plurality of positioning slots 1001, so that the positioning elastic pin 41 and the positioning slots 1001 perform preliminary positioning on the modular adsorption plate, thereby preventing the modular adsorption plate from excessively moving under the action of inertia, causing the modular adsorption plate to be misaligned with the frame where the horizontal fixed slide rail 5 and the vertical flip slide rail 7 are located, affecting the subsequent resetting of the vertical flip slide rail 7.

[0052] In summary: VOC treatment: the gas pipeline 3 is connected to the waste gas extraction equipment of the printing workshop, so that the waste gas from the transport workshop passes through the gas filter component through the gas pipeline 3, is adsorbed and filtered by the internal modular filter plate, and then is transmitted to the photocatalytic purification equipment 1 through the air intake pipe 2 for photocatalytic reaction purification, and finally the waste gas after VOC substance purification is discharged, completing the VOC treatment of the waste gas;

[0053] Before replacement: After the modular filter plate is used for a long time, the adsorption performance of the activated carbon particles inside it is significantly reduced. At this time, the transportation of the exhaust gas is stopped, and the driving rail 29 drives the internal electric sliding door 30 to slide downward until the electric sliding door 30 is completely inserted into the sealing door frame 28, and one end of the two adsorption tubes 4 is closed, so that the connection between the two adsorption tubes 4 and the air intake pipe 2 and the air delivery pipe 3 is disconnected, so as to prevent the residual exhaust gas in the air delivery pipe 3 from leaking into the plate changing box 14, the plate collecting box 15 or the photocatalytic purification device 1 through the unfolded air filter assembly, or directly leaking into the external environment. After the electric sliding door 30 closes the adsorption tube 4, the vacuum pump 31 is started, and the residual exhaust gas in the adsorption tube 4 and the air filter assembly is extracted into the air storage box 33 through the vacuum pipe 32 for temporary storage, thereby reducing the leakage of the residual exhaust gas in the adsorption tube 4 and the air filter assembly when replacing the modular filter plate;

[0054] During replacement: the sealing electric push rod 35 drives the sealing slide plate 36 to slide upward and disengage from the vertical flip slide rail 7 below. Each flip motor 9 drives the rotating shaft 6 to rotate, driving a total of four vertical flip slide rails 7 on both sides to flip from a vertical state to a horizontal state. The two vertical flip slide rails 7 located below will contact the support rails 17 on both sides respectively and be supported by the support rails 17. Then the push electric slide 20 inside the push box 18 slides along the push guide rail 19, and drives the push plate 22 to enter the plate changing box 14 through the push frame 21 and contact the most horizontal state of the plate changing box 14. The new modular filter plate is pushed into the filter assembly, and the modular filter plate slides out of the passage socket 16. The positioning slide block 11 moves along the replacement slide groove on the other side until the modular filter plate moves to the vertical flip slide rail 7, completing the docking of the internal track of the plate replacement box 14 and the horizontal fixed slide rail 5 to prevent the modular filter plate from being misaligned or offset during replacement. The new modular filter plate slides between the two vertical flip slide rails 7 on one side until the new modular filter plate contacts the old modular filter plate between the two horizontal fixed slide rails 5, so that it is pushed to the inside of the plate receiving box 15 through the vertical flip slide rail 7 on the other side, and then is transported to other areas by the conveying device inside the plate receiving box 15, so that the old modular filter plate is separated from the vertical flip slide rail 7, and then the pushing plate 22 is retracted into the inside of the pushing box 18, and the flip motor 9 drives the vertical flip slide rails 7 on both sides to reset, so that the upper and lower horizontal fixed slide rails 5 and the four vertical flip slide rails 7 on both sides are merged on the surrounding side of the new modular filter plate, and the vertical flip slide rail 7 is reset, and the sealing electric push rod 3 5 will drive the sealing slide plate 36 to slide down, so that the sealing slide plate 36 slides to the junction of the two vertical flip slide rails 7, so that the gap between the two vertical flip slide rails 7 is covered by the sealing slide plate 36, and the modular filter plate is replaced. Finally, the electric carry-in slide 24 inside the plate changing box 14 drives the carry-in frame 25 to move along the carry-in guide rail, so that the carry-in frame 25 pushes all the modular filter plates inside the plate changing box 14 to move a unit distance toward the position of the pass socket 16, so that the vacant positions of the modular filter plates are filled, so as to facilitate the subsequent replacement of the modular filter plates.

[0055] After replacement: the electric sliding door 30 slides upward to reset, so that the adsorption tube 4 is reconnected, and then the gas supply is restored. When the modular filter plates inside the plate changing box 14 are used up or insufficient, the staff can open the replacement magnetic suction door 26 and insert a batch of modular filter plates into the replacement socket 1402 in turn. The positioning sliders 11 at the top and bottom of the modular filter plates will slide in the replacement chute until the modular filter plates are completely inserted into the plate changing box 14 and contact the inner wall of the plate changing box 14. Then the carrying frame 25 pushes the modular filter plates to slide in the plate changing box 14, and the positioning sliders 11 on the modular filter plates are pushed into the replacement chute. It will also slide in the positioning groove 1401 to position the modular filter plate, so that the advancement rack 25 alternately pushes the new modular filter plates one by one into the innermost side of the plate changing box 14, thereby realizing the rapid replenishment of the modular filter plates. When the old modular adsorption plates in the plate collecting box 15 are recovered, the assembly ring 38 and the second filter screen 39 on the reinforcement frame 12 can be removed together, and then the activated carbon particles inside the adsorption frame 10 can be poured out for purification or directly replaced, and then the assembly ring 38 can be assembled on the reinforcement frame 12, so that the modular adsorption plate has sufficient adsorption performance again, so that it can be put into use again.
