Description

Technical Field

[0001] The invention relates to the field of waste gas treatment, and more specifically to a packaging box printing waste gas treatment device. Background Art

[0002] Packaging box printing waste gas refers to the gas containing volatile organic compounds generated in the packaging box printing process. Its main sources include the volatilization of organic solvents such as ink, diluent, and cleaning agent. Printing waste gas is a toxic and harmful gas containing a variety of harmful substances. Its emission will have a serious impact on the environment and human health. Therefore, the printing industry needs to adopt printing waste gas treatment equipment to reduce the emission of printing waste gas; In the prior art, activated carbon adsorption is usually used to adsorb and clean organic compounds in printing waste gas. For example, Chinese patent No. CN219186381U discloses an activated carbon adsorption box for printing waste gas treatment. By quickly collecting activated carbon bricks into a collection bag, the staff does not need to take out the activated carbon bricks from the pull-out box one by one and then bag them, which can effectively improve the efficiency of activated carbon replacement and reduce the workload. Activated carbon has a developed pore structure and a large specific surface area, which enables it to effectively adsorb gas molecules. When waste gas containing volatile organic compounds passes through the activated carbon layer, these organic substances are adsorbed in the micropores of the activated carbon, thereby achieving the purpose of purifying the waste gas. However, in the prior art, when printing waste gas is purified by activated carbon, when the gaps on the surface of the activated carbon are blocked by foreign matter in the waste gas, the adsorption performance of the activated carbon will be significantly reduced, thereby affecting the purification efficiency of the printing waste gas. The adsorption performance of activated carbon requires observation and judgment by the operator. In the actual operation process, there will not only be certain judgment errors, but also the problem of replacement of activated carbon that has not reached the saturated state, which will increase the loss of activated carbon in the waste gas treatment process and increase the operator's workload to a certain extent.

[0020] The activated carbon plate 35 has a fan-shaped structure, the number of the mounting grooves 52 is several groups and distributed in a ring array, the outer surface of the connecting shaft 21 is rotatably connected with an isolation sleeve 30, and the outer surface of the isolation sleeve 30 is fixedly connected to the mounting seat 26, the number of the storage grooves 33 and the elastic plates 34 is several groups and distributed symmetrically, and the elastic plates 34 are arc-shaped.

[0021] An air inlet pipe 19 is fixedly connected to the outer surface of the lower end of the treatment cylinder 11. The upper end of the treatment cylinder 11 is conical. An exhaust pipe 14 is fixedly connected to the outer surface of the upper end of the treatment cylinder 11. The outer surface of the lower end of the treatment cylinder 11 is fixedly connected to support legs 12. The number of the support legs 12 is three groups and distributed in a ring array.

[0022] By adopting the above technical solution, when the waste gas from printing of packaging boxes is treated by the treatment tube 11, the waste gas to be treated is firstly pressurized and injected into the treatment tube 11 through the air inlet pipe 19, and the treatment tube 11 fixes and supports the mounting seat 26. The waste gas from printing flows upward in the treatment tube 11 under the action of pressure, and at the same time, the motor 18 is started and operated, and the coupling shaft 21 is driven to rotate synchronously by the output shaft of the motor 18. The isolation sleeve 30 is separated between the mounting seat 26 and the coupling shaft 21, and the coupling shaft 21 drives the sealing sleeve 31 to rotate synchronously through the fixing block 32. The sealing sleeve 31 is in the cavity inside the mounting seat 26 through the bracket 29. The bracket 29 rotates in the cavity 53, the mounting groove 52 provided on the surface of the bracket 29 is used to place the activated carbon plate 35, and the storage groove 33 provided inside the mounting groove 52 is used to fix and support the elastic plate 34. The activated carbon plate 35 stays in the mounting groove 52 under the elastic force of the elastic plate 34, and the activated carbon plate 22 is supported by the elastic plate 34, so that the bracket 29 can drive the activated carbon plate 35 to rotate synchronously, and the sealing sleeve 31 can be rotated and sealed in the cavity 53. After the printing waste gas enters the cavity 53, the printing waste gas will pass through the activated carbon plate 35, and the activated carbon plate 35 will be used to support the printing waste gas in the cavity 53. The volatile organic compounds are adsorbed and removed. During the exhaust gas treatment process, the bracket 29 drives a plurality of groups of activated carbon plates 35 distributed in a ring array to continuously rotate inside the cavity 53 through the elastic plate 34. As the volatile organic compounds adsorbed on the surface of the activated carbon plate 35 gradually increase, the adsorption capacity of the activated carbon plate 35 gradually decreases while its weight continues to increase. When the gravity of the activated carbon plate 35 is greater than the friction between the elastic plate 34 and the activated carbon plate 35, the activated carbon plate 35 will slide downward along the inside of the mounting groove 52. At this time, the lower end of the activated carbon plate 35 will rotate and contact with the lower end of the inner surface of the cavity 53. When the activated carbon plate When the activated carbon plates 35 move to the discharge port 49, they will fall from the discharge port 49 under the action of gravity, so that the group of activated carbon plates 35 can be disassembled in time. By setting a material replacement component, the adsorption capacity of the activated carbon plates 35 is monitored by utilizing the gravity change of the activated carbon plates 35, so that the saturated activated carbon plates 35 can be removed, so that the activated carbon plates 35 can maintain good adsorption performance, which helps to improve the treatment quality of printing waste gas. At the same time, by setting several groups of activated carbon plates 35 and replacing the activated carbon plates 35 individually, the adsorption performance of the activated carbon plates 35 can be fully utilized.

[0023] like Figure 4 and Figure 5As shown, a discharge trough 15 is provided on the outer surface of the processing cylinder 11, and a sealing groove 51 is embedded on the inner side of the processing cylinder 11. The sealing groove 51 is connected with the inside of the discharge trough 15. A sealing plate 16 is slidably connected to the inner side of the sealing groove 51. The sealing plate 16 is in an arc shape. A stopper 17 is fixedly connected to the outer surface of the sealing plate 16. A breathable groove 27 is provided on the outer surface of the upper end of the mounting seat 26. The lower end of the breathable groove 27 is connected with the inside of the cavity 53.

[0024] By adopting the above technical scheme, when the activated carbon plate 35 reaches a saturated state and is discharged from the inside of the mounting seat 26, it is necessary to replenish and replace the group of activated carbon plates 35. At this time, the operator slides the sealing plate 16 upward from the inside of the sealing groove 51 through the block 17, opens the discharge groove 15 through the sealing plate 16, and then extends the activated carbon plate 35 into the inside of the treatment tube 11 through the discharge groove 15, and then places the activated carbon plate 35 in the mounting groove 52 on the surface of the bracket 29 through the air permeable groove 27, thereby completing the rapid disassembly and replacement of the activated carbon plate 35, and then the sealing plate 16 slides downward along the sealing groove 51 under the action of the block 17 and its own gravity, and the discharge groove 15 is blocked and sealed by the sealing plate 16, thereby reducing the probability of gas leakage from the inside of the treatment tube 11 from the discharge groove 15. After the printing waste gas is filtered and processed by the activated carbon plate 35 inside the cavity 53, it continues to flow and diffuse upward from the air permeable groove 27 on the upper surface of the mounting seat 26.

[0025] like Figure 4 and Figure 6 As shown, a discharge assembly is provided at the lower side of the mounting seat 26, and the discharge assembly includes a partition 48 fixedly connected to the lower end of the inner surface of the processing cylinder 11, and a second air vent 28 is provided on the outer surface of the lower end of the mounting seat 26, and the first air vent 27 is located directly above the second air vent 28. The outer surface of the upper end of the partition 48 is fixedly connected to the lower end of the mounting seat 26, and a discharge port 49 is provided on the outer surface of the lower end of the mounting seat 26 between the two groups of partitions 48.

[0026] A spring 42 is fixedly connected to the lower end of the inner surface of the processing cylinder 11, a buffer plate 44 is fixedly connected to the outer surface of the upper end of the spring 42, a contact plate 46 is fixedly connected to the outer surface of the lower end of the buffer plate 44, a contact plate 47 is fixedly connected to the lower end of the inner surface of the processing cylinder 11, and the contact plate 46 is located directly above the contact plate 47. A material extraction trough 13 is opened on the outer surface of the processing cylinder 11.

[0027] By adopting the above technical solution, the partition 48 is located between the mounting seat 26 and the lower end of the inner surface of the treatment cylinder 11, and a closed space is formed inside the treatment cylinder 11 through the two groups of partitions 48 cooperating with the mounting seat 26. The upper end of the partition 48 is in rotational contact with the outer surface of the lower end of the bracket 29, so that the partition 48 and the bracket 29 can be sealed. The printing waste gas enters the cavity 53 through the air permeable groove 28, and when the activated carbon plate 35 in a saturated state falls from the discharge port 49, the activated carbon plate 35 will fall on the outer surface of the buffer plate 44, and the treatment cylinder 11 supports the buffer plate 44 through the spring 1 42. The buffer plate 44 will compress the spring 1 42 under the gravity of the activated carbon plate 35, and the buffer plate 44 In the process of moving downward, the contact plate 1 46 will be driven to move downward synchronously, so that the contact plate 1 46 is in contact with the contact plate 2 47. The contact plate 1 46 and the contact plate 2 47 send an electrical signal to the exhaust gas treatment equipment control system at the moment of contact. The control system sends an early warning to remind the operator to promptly remove the saturated activated carbon plate 35 through the material taking trough 13, and replace the activated carbon plate 35 in time to ensure the operating stability of the printing exhaust gas treatment equipment. By setting a material taking component to remind the user to replace the saturated activated carbon plate 35 in time, the operating convenience and flexibility of the printing exhaust gas treatment equipment can be improved to a certain extent, and the treatment effect of the printing exhaust gas can also be guaranteed.

[0028] like Figure 4 , Figure 6 and Figure 8 As shown, an adjustment component is provided at the lower end of the inner surface of the treatment cylinder 11, and the adjustment component includes a fixed cover 36 fixedly connected to the lower end of the inner surface of the treatment cylinder 11, and the fixed cover 36 is located directly above the air inlet pipe 19. The outer surface of the fixed cover 36 is provided with slots 37, and the number of the slots 37 is several groups and distributed in a ring array. The inner surface of the fixed cover 36 is fixedly connected to a filter screen 43.

[0029] The outer surface of the upper end of the filter screen 43 is fixedly connected to a movable rod 38, and the outer surface of the movable rod 38 is slidably connected to a sliding sleeve 39. The outer surface of the lower end of the sliding sleeve 39 is fixedly connected to a top sleeve 40, and the top sleeve 40 is in a circular ring shape. The outer surface of the sliding sleeve 39 is fixedly connected to an extrusion plate 41, and the outer surface of the upper end of the extrusion plate 41 is fixedly connected to a spring 2 45, and the upper end of the spring 2 45 is fixedly connected to the upper end of the inner surface of the fixed cover 36.

[0030] By adopting the above technical solution, the amount of waste gas generated during the printing process of the packaging box will fluctuate to a certain extent. In order to improve the quality of waste gas treatment, it is necessary to maintain the treatment flow rate of the waste gas within an appropriate range. For this purpose, an adjusting component is provided. When the printing waste gas is injected into the treatment cylinder 11 through the air inlet pipe 19, the printing waste gas will pass through the filter 43 and enter the fixed cover 36. The large particles of impurities in the printing waste gas will be initially filtered and treated by the filter 43, thereby reducing the probability of large particles of impurities in the waste gas clogging the activated carbon plate 35. After the printing waste gas enters the upper side of the filter 43, it will diffuse from the notch 37 on the surface of the fixed cover 36 to the inside of the treatment cylinder 11. The spring 45 pulls and supports the extrusion plate 41. At the same time, the extrusion plate 41 can separate and seal the notch 37 on the surface of the fixed cover 36. The printing waste gas will blow the extrusion plate 41 so that the extrusion plate 41 drives the sliding sleeve 39 to slide along the surface of the movable rod 38. The movable rod 38 guides the extrusion plate 41 through the sliding sleeve 39 The support is directed to the direction, so that the extrusion plate 41 can slide smoothly up and down. When the amount of printing waste gas generated increases, the extrusion plate 41 will slide upward under the blowing of the gas, and the spring 2 45 will apply a certain buffering force to the extrusion plate 41. Under the blocking effect of the spring 2 45, the upward sliding distance of the extrusion plate 41 can be reduced. The movement of the extrusion plate 41 can buffer and adjust the air outlet at the slot 37, thereby reducing the air volume fluctuation inside the treatment cylinder 11, and maintaining the air intake of the printing waste gas within an appropriate range, thereby further improving the treatment quality of the printing waste gas. When the exhaust gas intake is too small, the extrusion plate 41 and the sliding sleeve 39 will slide downward under the action of gravity, and the sliding sleeve 39 will drive the top sleeve 40 to move downward synchronously. The top sleeve 40 will collide with the upper surface of the filter screen 43 during the falling process, and the filter screen 43 is knocked by the top sleeve 40, so that the large particles of impurities attached to the surface of the filter screen 43 can be cleaned, thereby ensuring the filtering effect of the filter screen 43.

[0031] like Figure 4 and Figure 7 As shown, an adsorption assembly is provided inside the treatment cylinder 11, and the adsorption assembly includes a movable seat 20 fixedly connected to the inner surface of the treatment cylinder 11, an activated carbon 1 22 is slidably connected to the inner surface of the movable seat 20, an activated carbon 2 23 is fixedly connected to the outer surface of the lower end of the activated carbon 1 22, and the connecting shaft 21 passes through the upper sides of the activated carbon 1 22 and the activated carbon 23.

[0032] A movable groove 50 is formed on the outer surface of the lower end of the activated carbon 23, and a guide plate 25 is fixedly connected to the inner surface of the movable groove 50. The guide plate 25 is spiral-shaped. A push rod 24 is fixedly connected to the outer surface of the connecting shaft 21. The push rod 24 is L-shaped, and the upper end of the push rod 24 is in movable contact with the outer surface of the lower end of the guide plate 25.

[0033] By adopting the above technical solution, the gas filtered by the activated carbon plate 35 will continue to flow upward, and the gas will be secondary adsorbed and filtered by the activated carbon 1 22 and the activated carbon 2 23, so that the treatment effect of the printing waste gas can be further improved. The treatment cylinder 11 will slide and support the activated carbon 1 22 through the movable seat 20. The activated carbon 23 on the lower side of the activated carbon 1 22 can effectively increase the contact area between the activated carbon and the gas, so as to improve the waste gas treatment efficiency to a certain extent. The activated carbon 23 fixes and supports the guide plate 25 through the movable groove 50. The connecting shaft 21 will drive the push rod 24 to rotate synchronously during the rotation process. The push rod 24 will slide and contact the lower surface of the guide plate 25 during the rotation process. The guide plate 25 is spiral. The activated carbon 23 and the activated carbon 1 22 are lifted upward by the guide plate 25, so that the activated carbon 1 22 can slide upward inside the movable seat 20. When the push rod 24 is out of contact with the guide plate 25, the activated carbon 1 22 and the activated carbon 2 23 slide downward under the action of gravity. The activated carbon 1 22 and the activated carbon 2 23 can be reciprocated up and down to shake off the foreign particles attached to their surfaces, thereby reducing the probability of activated carbon 1 22 and activated carbon 2 23 being blocked, helping to ensure the permeability of activated carbon 1 22 and activated carbon 2 23 and effectively prolonging the working time of activated carbon 1 22 and activated carbon 2 23. The gas that has been filtered again is discharged to the outside of the treatment tube 11 through the exhaust pipe 14 on the upper side of the treatment tube 11.

[0034] Instructions for use: When filtering the printing waste gas, the waste gas is injected into the fixed cover 36 through the air inlet pipe 19, and the large particles of impurities in the printing waste gas are initially filtered through the filter screen 43. The printing waste gas blows the extrusion plate 41 so that the extrusion plate 41 drives the sliding sleeve 39 to slide along the surface of the movable rod 38. The movement of the extrusion plate 41 can buffer and adjust the air volume at the notch 37, thereby reducing the fluctuation of the air volume inside the treatment cylinder 11. The printing waste gas enters the cavity 53 through the air permeable groove 28, and the volatile organic compounds in the printing waste gas are removed by the activated carbon plate 35. The activated carbon plates 35 in a saturated state will fall from the discharge port 49 under the action of gravity so that the saturated activated carbon plates 35 can be removed. The gas can be secondary adsorbed and filtered by the activated carbon 1 22 and the activated carbon 2 23. The foreign particles attached to the surface of the activated carbon 1 22 and the activated carbon 2 23 can be shaken off by the up and down reciprocating movement of the activated carbon 1 22 and the activated carbon 2 23, thereby effectively extending the working time of the activated carbon 1 22 and the activated carbon 2 23.

[0035] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
