DETAILED DESCRIPTION

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.10 and Fig.13 As shown, a waste gas treatment device for environmentally friendly carton printing according to the present invention comprises a connection box 1, two connection sleeves 3 are fixedly connected to the inside of the connection box 1, an adsorption structure 2 is provided on the connection box 1, an opening and closing structure 4 is provided on the connection sleeve 3, two connection pipes 5 are fixedly connected to the outside of the connection box 1, a fixing structure 6 is provided on the connection box 1, a supporting structure 7 is provided on the connection box 1, a clamping structure 8 is provided on the supporting structure 7, an air intake pipe 9 is fixedly connected to one side of the connection box 1, and an exhaust pipe 10 is fixedly connected to the other side of the connection box 1;

[0037] like Figure 4 , Figure 5 , Figure 6 , Figure 7 , Fig.10 and Fig.11As shown, the opening and closing structure 4 includes a slide rod 402 and a first baffle 403, the connecting sleeve 3 is slidably connected to two slide rods 402, the connecting sleeve 3 is internally installed with two electric push rods 401, the extended end of the electric push rod 401 is fixedly connected to one end of the slide rod 402, the other end of the slide rod 402 is fixedly connected to the first baffle 403, the first baffle 403 is slidably connected to the connecting sleeve 3, the slide rod 402 is fixedly connected to a connecting rod 404, the connecting rod 404 is slidably connected to a connecting pipe 5, the connecting pipe 5 is internally slidably connected to a second baffle 405, the second baffle 405 is fixedly connected to the adjacent connecting rod 404, the adsorption structure 2 includes a connecting frame 201 and a trawl net 2 02, a connecting frame 201 is slidably connected to the connecting box 1, a plurality of trawl nets 202 are fixedly connected to the connecting frame 201, a plurality of openings 204 are respectively provided on both sides of the connecting frame 201, a plurality of activated carbon honeycomb blocks 203 are placed on the top of the trawl net 202, two supporting plates 206 are fixedly connected to the inside of the connecting sleeve 3, a connecting frame 201 is slidably connected between the two opposing supporting plates 206, the bottom end of the connecting frame 201 is rotatably connected to two rotating wheels 205, the cross section of the supporting plate 206 is L-shaped, the cross section of the connecting rod 404 is L-shaped, two sealing pads 11 are clamped on the connecting box 1, and the sealing pads 11 conflict with the adjacent connecting frames 201, that is: during use The exhaust pipe 10 can be connected to one end of the fan, and the exhaust pipe can be connected to the intake pipe 9. Then, the working gas of the fan will enter the interior of the connection box 1 from the intake pipe 9. The air entering the connection box 1 will first enter the interior of one of the connection sleeves 3. During the flow of the exhaust gas inside one of the connection sleeves 3, the exhaust gas can be adsorbed and purified by multiple activated carbon honeycomb blocks 203 inside one of the connection sleeves 3. After the air is discharged from one of the connection sleeves 3, it will enter the interior of another connection sleeve 3 for purification again. The purified air will finally be discharged from the exhaust pipe 10. When it is necessary to replace the activated carbon honeycomb block 203 inside one of the connection sleeves 3, the connection sleeves 3 can be started at the same time. 3, the electric push rod 401 extends to drive the sliding rod 402 to slide on the connecting sleeve 3, the movement of the sliding rod 402 will drive the first baffle 403 to slide on the connecting sleeve 3, and at the same time, the movement of one of the sliding rods 402 will also drive the connecting rod 404 to move, and the movement of the connecting rod 404 will drive the second baffle 405 to slide on the connecting pipe 5. When the two first baffles 403 form a seal on the connecting sleeve 3, the electric push rod 401 stops extending. At this time, since the second baffle 405 does not seal the connecting pipe 5, the exhaust gas can enter the inside of the other connecting sleeve 3 through the connecting pipe 5 to continue the purification work, thereby avoiding the need to stop during the replacement of the activated carbon honeycomb block 203, so that the air purification can be carried out continuously.This prevents the unpurified waste gas from drifting into the surrounding environment during the replacement of the activated carbon honeycomb block 203 and causing damage to the workers, thereby improving the stability and safety of use.

[0038] Specifically, Figure 1 , Figure 2 , Figure 3 and Fig.12As shown, the fixed structure 6 includes a connecting block 601 and a pressure plate 602, one side of the connecting frame 201 is rotatably connected with the connecting block 601, the connecting block 601 is slidably connected with the pressure plate 602, one side of the connecting box 1 is fixedly connected with four baffles 603, the two ends of the pressure plate 602 are respectively in contact with two of the baffles 603, the baffles 603 are threadedly connected with a screw rod 605, one end of the screw rod 605 is fixedly connected with a rotating rod 604, the other end of the screw rod 605 is rotatably connected with a block 606, the block 606 is in contact with the connecting frame 201, the rotating rod 604 is perpendicular to the screw rod 605, the cross section between the screw rod 605 and the block 606 is a T-shaped structure, and the connecting block 60 The middle part of the connecting frame 1 is a hexagonal prism structure, the two ends of the connecting block 601 are cylindrical structures, the cross section of one end of the connecting block 601 is a T-shaped structure, the cross section of the baffle 603 is an L-shaped structure, the supporting structure 7 includes a supporting block 701 and a first connecting shaft 702, one side of the connecting box 1 is fixedly connected with four supporting blocks 701, the bottom end of the rotating wheel 205 is in conflict with the adjacent supporting blocks 701, two of the supporting blocks 701 located at the bottom of the connecting frame 201 are fixedly connected with the same first connecting shaft 702, the two ends of the first connecting shaft 702 are rotatably connected to two towing rods 703, the end of the towing rod 703 is rotatably connected to the second connecting shaft 704, and the two ends of the second connecting shaft 704 are fixedly connected There are two support rods 705, that is, when the activated carbon honeycomb block 203 needs to be replaced, the two rotating rods 604 on one side of one of the connecting frames 201 can be rotated in turn, and the rotation of the rotating rod 604 drives the screw 605 to rotate. The screw 605 will drive the block 606 to move away from the pressure plate 602 during the rotation. When the two blocks 606 are not in conflict with the pressure plate 602, the pressure plate 602 can be rotated from a horizontal state to a vertical state, and then the pressure plate 602 can be pulled to slide on the connecting block 601, so that there is a certain gap between the pressure plate 602 and the connecting block 601, and then the pressure plate 602 can be held to pull the connecting frame 201 out of the inside of the connecting box 1. During the movement of the connecting frame 201, its bottom The rotating wheel 205 at the end will roll on the towing rod 703, so that the connecting frame 201 can be supported by the towing rod 703 during the movement of the connecting frame 201, so that the movement of the connecting frame 201 is smoother. When the connecting frame 201 is pulled out, the hand can be inserted into the interior of the connecting frame 201 through the opening 204, and then the old activated carbon honeycomb block 203 can be taken off the trawl net 202, and the new activated carbon honeycomb block 203 can be placed on the trawl net 202. After the replacement is completed, the connecting frame 201 is pushed into the interior of the connecting box 1, and then the pressure plate 602 is rotated. When the pressure plate 602 is rotated to a horizontal state, its end will contact with the baffle 603, and then the two rotating rods 604 can be rotated in opposite directions in turn to make the two abutting blocks 606 press against the pressure plate 602.After the abutment block 606 and the pressure plate 602 are pressed tightly, the connection frame 201 will also be pressed tightly against the connection box 1, thereby realizing the rapid installation of the connection frame 201. The sealing performance between the connection frame 201 and the connection box 1 can be improved by providing the sealing pad 11.

[0039] Specifically, Figure 7 , Figure 8 , Fig. 9 ,and Fig.13 As shown, the clamping structure 8 includes a pull block 801 and a pull groove 802, the pull block 801 is slidably connected to the tow bar 703, the pull block 801 is provided with a pull groove 802, the interior of the tow bar 703 is slidably connected with two clamping blocks 804, one end of the clamping block 804 is fixedly connected to a connecting rope 803, the two connecting ropes 803 are respectively fixedly connected to the two sides of the pull block 801, and the second connecting shaft 704 is provided with two first clamping grooves 806, one end of one of the clamping blocks 804 is connected to the adjacent first clamping groove 806 The first connecting shaft 702 is provided with four second card slots 807, another card block 804 is engaged with one of the adjacent second card slots 807, the outer sleeve of the connecting rope 803 is provided with a reset spring 805, one end of the reset spring 805 abuts against the card block 804, and the other end of the reset spring 805 abuts against the towing rod 703, and the cross section of one end of the card block 804 is a trapezoidal structure, that is, when the activated carbon honeycomb block 203 does not need to be replaced, the pull block 801 can be pulled, and the pull slot 80 is set on the pull block 801. 2 can avoid slipping when pulling the pull block 801, so that it is more convenient to use. The movement of the pull block 801 will drive the two clamping blocks 804 to move through the two connecting ropes 803, so that one of the clamping blocks 804 moves away from one of the first clamping slots 806, and the other clamping block 804 moves away from one of the second clamping slots 807. When one of the clamping blocks 804 is not engaged with one of the first clamping slots 806, the other clamping block 804 will also be not engaged with one of the second clamping slots 807, and then it can be turned toward the connection box 1. The drag rod 703 is moved, and the support rod 705 is rotated toward the drag rod 703. When the drag rod 703 and the support rod 705 are rotated ninety degrees, one of the blocks 804 will be engaged with the other first slot 806 under the action of the return spring 805, and the other block 804 will be engaged with the other second slot 807. At this time, the drag rod 703 is attached to one side of the connection box 1, and the support rod 705 is also attached to one side of the drag rod 703. Therefore, the drag rod 703 and the support rod 705 can be folded and stored, which reduces the space occupied and is more convenient for transportation and storage.

[0040] When the present invention is in use, the exhaust pipe 10 can be connected to one end of the fan, and the exhaust pipe can be connected to the intake pipe 9. Then, the working gas of the fan will enter the interior of the connection box 1 from the intake pipe 9. The air entering the connection box 1 will first enter the interior of one of the connection sleeves 3. During the flow of the exhaust gas inside one of the connection sleeves 3, the exhaust gas can be adsorbed and purified by multiple activated carbon honeycomb blocks 203 inside one of the connection sleeves 3. After the air is discharged from one of the connection sleeves 3, it will enter the interior of another connection sleeve 3 for purification again. The purified air will finally be discharged from the exhaust pipe 10. When it is necessary to replace the activated carbon honeycomb block 203 inside one of the connection sleeves 3, the two electric push rods 401 inside the connection sleeve 3 can be started at the same time. The electric push rod 401 extends to drive the slide rod 4 02 slides on the connecting sleeve 3, and the movement of the sliding rod 402 will drive the first baffle 403 to slide on the connecting sleeve 3. At the same time, the movement of one of the sliding rods 402 will also drive the connecting rod 404 to move, and the movement of the connecting rod 404 will drive the second baffle 405 to slide on the connecting pipe 5. When the two first baffles 403 form a seal on the connecting sleeve 3, the electric push rod 401 stops extending. At this time, since the second baffle 405 does not seal the connecting pipe 5, the exhaust gas can enter the interior of the other connecting sleeve 3 through the connecting pipe 5 to continue the purification work, thereby avoiding the need to stop the machine during the process of replacing the activated carbon honeycomb block 203, so that the air purification can be carried out continuously, and avoiding the exhaust gas that has not been purified during the process of replacing the activated carbon honeycomb block 203 from drifting into the surrounding environment and causing damage to the body of the staff, thereby improving the stability and safety of use;

[0041] When the activated carbon honeycomb block 203 needs to be replaced, the two rotating rods 604 on one side of one of the connecting frames 201 can be rotated in turn. The rotation of the rotating rod 604 drives the screw 605 to rotate. The screw 605 drives the stop block 606 to move away from the pressure plate 602 during the rotation. When the two stop blocks 606 do not interfere with the pressure plate 602, the pressure plate 602 can be rotated from a horizontal state to a vertical state, and then the pressure plate 602 can be pulled to slide on the connecting block 601, so that there is a certain gap between the pressure plate 602 and the connecting block 601, and then the pressure plate 602 can be held to pull the connecting frame 201 out of the inside of the connecting box 1. During the movement of the connecting frame 201, the rotating wheel 205 at its bottom end will roll on the towing rod 703, so that the connecting frame 201 can be moved by the towing rod 703 during the movement of the connecting frame 201 is supported to make the movement of the connecting frame 201 smoother. When the connecting frame 201 is pulled out, the hand can be extended into the interior of the connecting frame 201 through the opening 204, and then the old activated carbon honeycomb block 203 is removed from the trawl net 202, and the new activated carbon honeycomb block 203 is placed on the trawl net 202. After the replacement is completed, the connecting frame 201 is pushed into the interior of the connecting box 1, and then the pressure plate 602 is rotated. When the pressure plate 602 is rotated to a horizontal state, its end will contact the baffle 603, and then the two rotating rods 604 can be rotated in reverse order to make the two abutting blocks 606 press against the pressure plate 602. After the abutting blocks 606 and the pressure plate 602 are pressed tightly, the connecting frame 201 will also press against the connecting box 1, thereby realizing the rapid installation of the connecting frame 201. By setting the sealing pad 11, the sealing between the connecting frame 201 and the connecting box 1 can be improved.

[0042] When the activated carbon honeycomb block 203 does not need to be replaced, the block 801 can be pulled. By setting a pull groove 802 on the block 801, it is possible to avoid slipping when the block 801 is pulled, so that it is more convenient to use. The movement of the block 801 will drive the two clamping blocks 804 to move through the two connecting ropes 803, so that one of the clamping blocks 804 moves away from one of the first clamping grooves 806, and the other clamping block 804 moves away from one of the second clamping grooves 807. When one of the clamping blocks 804 is not engaged with one of the first clamping grooves 806, the other clamping block 804 will also engage with one of the second The slots 807 are not engaged, and then the tow rod 703 can be rotated toward the connection box 1, and the support rod 705 can be rotated toward the tow rod 703 at the same time. When the tow rod 703 and the support rod 705 are rotated ninety degrees, one of the blocks 804 will engage with the other first slot 806 under the action of the return spring 805, and the other block 804 will engage with the other second slot 807. At this time, the tow rod 703 is attached to one side of the connection box 1, and the support rod 705 is also attached to one side of the tow rod 703. Therefore, the tow rod 703 and the support rod 705 can be folded and stored, which reduces the space occupied and is more convenient for transportation and storage.
