Description

Technical Field

[0001] The invention relates to the technical field of waste gas treatment, and in particular to a printing waste gas treatment system. Background Art

[0002] Printing is the process of transferring the approved printing plate to the substrate through printing machinery and special ink.

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1: Please refer to Figures 1 to 7 The present invention provides a technical solution: a printing waste gas treatment system, comprising a dust removal box 1, an air duct 11, an adsorption box 12, a mounting frame 13 and a dust removal bag 14, wherein the air duct 11 is fixedly mounted above the dust removal box 1 and communicated with the dust removal box 1, the adsorption box 12 is fixedly mounted at the bottom of the dust removal box 1 and communicated with the dust removal box 1, the mounting frame 13 is movably mounted in the inner cavity of the dust removal box 1, the dust removal bag 14 is mounted in the inner cavity of the mounting frame 13, a toggle assembly is arranged on the adsorption box 12, the toggle assembly comprises a carbon box 2, the carbon box 2 is movably mounted in the inner cavity of the adsorption box 12, a fixing frame 21 is fixedly mounted on the bottom of the carbon box 2, a servo motor 22 is fixedly mounted on the inner side of the fixing frame 21, and an electric push rod 23 is fixedly mounted on the output shaft of the servo motor 22;

[0036] A first fixing plate 24 is fixedly mounted on the output shaft of the electric push rod 23, a driving arm 25 is movably mounted on the surface of the first fixing plate 24, a driven arm 26 is movably mounted on one end of the driving arm 25 away from the first fixing plate 24, a second fixing plate 27 is movably mounted on one end of the driven arm 26 away from the driving arm 25, a positioning plate 211 is movably mounted on the top of the second fixing plate 27, the positioning plate 211 is fixedly mounted on the inner cavity surface of the carbon box 2, and a scraper 28 is fixedly mounted on one end of the driven arm 26 close to the driving arm 25;

[0037] An air outlet 29 is provided at the edge of the bottom of the carbon box 2, and an air outlet pipe 210 is fixedly installed in the air outlet 29;

[0038] The electric push rod 23 is movably installed between the carbon box 2, and the battery installation port of the electric push rod 23 is located below the carbon box 2. A filter screen is provided in the air outlet 29, and the pore size of the filter screen is smaller than the particle size of the activated carbon;

[0039] The servo motor 22 is provided with a vibration component, and the vibration component is used to improve the exhaust gas treatment efficiency.

[0040] Specifically, when in use, firstly, the other filtering devices in the system of the air outlet pipe 210 are connected, and then the exhaust gas is introduced into the dust bag 14 in the inner cavity of the dust removal box 1 through the air guide pipe 11. The dust bag 14 can filter the large-size particles in the exhaust gas, and the filtered exhaust gas is introduced into the inner cavity of the adsorption box 12. The activated carbon in the inner cavity of the carbon box 2 adsorbs the harmful substances in the exhaust gas, and the adsorbed and filtered exhaust gas flows into other filtering devices through the air outlet pipe 210;

[0041] Among them, the dust removal bag 14 can be set as an open design, such as the attached Figure 5, and the exhaust gas is directly introduced into it. It should be noted that this design can make the filter holes of the dust bag 14 larger to facilitate the passage of gas. The bottom needs to be sealed to facilitate the collection of particles. In addition, it can also be designed as a bag curtain to directly capture the particles in the exhaust gas. The specific operation can be selected according to the actual situation;

[0042] During the adsorption process, the servo motor 22 is started intermittently, so that the servo motor 22 drives the electric push rod 23 to rotate, and the electric push rod 23 can drive the first fixed plate 24 to rotate, so that the first fixed plate 24 drives the driving arm 25, the driven arm 26 and the scraper 28 to rotate, so that the activated carbon in the inner cavity of the carbon box 2 is turned over, so that different surfaces of the activated carbon can contact the exhaust gas. In addition, the activated carbon that is not easy to contact the exhaust gas can be turned to a position that contacts the exhaust gas first, so that the activated carbon can be fully adsorbed, the adsorption effect is improved, and the replacement frequency is reduced;

[0043] Furthermore, in the subsequent maintenance process, since the activated carbon absorbs harmful substances, when replacing the activated carbon, the outlet pipe 210 connected to other filtering equipment ends can be removed and connected to the desorption box, and then the filter plate in the outlet 29 is removed, and the servo motor 22 is started to drive the scraper 28 to rotate, and the scraper 28 is used to guide the activated carbon in the inner cavity of the carbon box 2 through the outlet 29 and the outlet pipe 210 into the desorption box, so that manual contact operations can be reduced, the automation of the equipment can be improved, and the safety of the user can be guaranteed;

[0044] Furthermore, after the activated carbon in the inner cavity of the carbon box 2 is discharged, the electric push rod 23 can be started to drive the first fixed plate 24 to rise, so that the first fixed plate 24 drives the driving arm 25, and the driving arm 25 can drive the driven arm 26 to drive until the scraper 28 contacts the inner cavity wall of the carbon box 2, and then the servo motor 22 is started to drive the scraper 28 to rotate, so that the scraper 28 cleans the impurities attached to the inner cavity wall of the carbon box 2, so as to avoid contamination of the newly introduced activated carbon and affect the adsorption effect of the activated carbon;

[0045] It should be noted that when it is difficult for the scraper 28 to introduce all the active carbon into the air outlet 29, the remaining activated carbon can be introduced into the air outlet 29 with the assistance of tools, and physical contact is not allowed.

[0046] Example 2: Please refer to Figures 2 to 5The vibration assembly includes a first rotating wheel 3, which is fixedly sleeved on the outer surface of the output shaft of the servo motor 22, and the outer surface of the first rotating wheel 3 is transmission-connected with a transmission belt 31, and the side of the transmission belt 31 away from the first rotating wheel 3 is transmission-connected with a second rotating wheel 32, and a support plate is movably installed at the bottom of the second rotating wheel 32, and the support plate is fixedly installed at the bottom of the carbon box 2, and a rotating rod 33 is fixedly installed in the middle of the second rotating wheel 32, and a first fixed block 34 is movably installed on the outer surface of the rotating rod 33, and the first fixed block 34 is fixedly installed on the outer surface of the adsorption box 12, and an eccentric wheel 35 is fixedly installed on the top of the rotating rod 33;

[0047] There is a distance between the side of the mounting frame 13 close to the eccentric wheel 35 and the inner cavity wall of the dust removal box 1. A guide column 36 is fixedly installed on the side of the mounting frame 13 close to the eccentric wheel 35. A first return spring 37 is sleeved on the outer peripheral side of the guide column 36. A mounting plate 38 is movably installed on the outer surface of the guide column 36. A vibration column 39 is fixedly installed on the surface of the mounting plate 38. A touch frame 310 is fixedly installed on the side of the mounting plate 38 away from the vibration column 39. The touch frame 310 is movably installed between the dust removal box 1, and the eccentric wheel 35 is located outside the touch frame 310.

[0048] On the basis of Example 1, when the servo motor 22 is started, it can drive the first rotating wheel 3 to rotate, and the first rotating wheel 3 can drive the transmission belt 31, so that the transmission belt 31 drives the second rotating wheel 32 to rotate, and the second rotating wheel 32 can drive the rotating rod 33 to rotate, so that the rotating rod 33 drives the eccentric wheel 35 to rotate;

[0049] The eccentric wheel 35 can be used to drive the touch frame 310, so that the touch frame 310 drives the mounting plate 38, so that the mounting plate 38 moves on the outer surface of the guide column 36, and then the vibration column 39 touches the mounting frame 13, so that the dust bag 14 vibrates. When the dust bag 14 vibrates, large-size particles on the surface of its inner cavity can be shaken off to the bottom, so as to avoid the particles from clogging the inner cavity surface of the dust bag 14, thereby improving the gas passing rate of the dust bag 14 and improving the exhaust gas treatment efficiency;

[0050] After the eccentric wheel 35 rotates 180 degrees, the eccentric wheel 35 and the touch frame 310 are gradually separated. At this time, the elastic force provided by the first reset spring 37 can reset the mounting plate 38, so that the vibration column 39 can continue to touch the mounting frame 13, thereby continuing the vibration process.

[0051] Example 3: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7A maintenance assembly is provided below the carbon box 2, and the maintenance assembly includes a base 4, which is located below the carbon box 2, and a bidirectional hydraulic cylinder 41 is fixedly installed on the upper surface of the base 4, and a driving block 42 is fixedly installed on the output shaft of the bidirectional hydraulic cylinder 41, and a guide column 43 is movably installed in the middle of the driving block 42, and the guide column 43 is fixedly installed on the inner side of the base 4;

[0055] On the basis of Example 1, after the exhaust gas is filtered, the driving block 42 can be driven to move by starting the bidirectional hydraulic cylinder 41, so that the driving block 42 drives the first connecting member 44 to move, and the first connecting member 44 can drive the push rod 45, so that the push rod 45 drives the carbon box 2 to descend, so that the carbon box 2 is separated from the adsorption box 12, which is convenient for the user to replace the activated carbon in the adsorption box 12;

[0056] At the same time, when the driving block 42 moves, it can drive the connecting frame 48 to move, so that the connecting frame 48 drives the installation frame 13 to move, so that the connection part between the installation frame 13 and the dust bag 14 is moved to the outside of the dust removal box 1, which is convenient for the user to replace the dust bag 14 and improves maintenance efficiency.

[0057] Example 4: Please refer to Figure 1 , Figure 3 and Figure 8 A cleaning assembly is provided on the air guide tube 11, and the cleaning assembly includes a third fixing plate 5.

[0060] The thin rope 510 is in active contact with the air guide tube 11, and a sealing ring is provided at the connection between the two.

[0061] The length of the second return spring 51 is greater than the spacing between adjacent cleaning rings 54 , and the thin cable 510 is fixedly connected to the middle of the center plate 55 .

When the thin rope 510 is gathered, it will drive the center plate 55 to descend, and the center plate 55 can drive the cleaning ring 54 to descend, so as to clean the particulate matter attached to the inner wall surface of the air guide tube 11, so as to avoid the particulate matter attachment layer being too thick, resulting in a reduction in the intake volume, and reducing the exhaust gas treatment efficiency;

[0063] When the cleaning ring 54 has cleaned the attached matter, the attached matter will fall into the dust bag 14 which is also in motion. After the cleaning ring 54 has cleaned, the driving block 42 will continue to drive the cleaning ring 54 to descend for a certain distance, so that the fourth fixing plate 52 continues to squeeze the second return spring 51. The extra distance of the driving block 42 will move the connection between the mounting frame 13 and the dust bag 14 to the outside of the dust removal box 1.
