Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, and more specifically, to a waste gas treatment device for a gift box gluing production line. Background Technology

[0002] The automated glue coating production line for gift box production includes steps such as glue coating, drying, and conveying. During the drying process, waste gas is generated, which can be harmful to the environment and workers. Currently, automated glue coating production lines are equipped with waste gas treatment equipment that uses built-in high-efficiency activated carbon to treat the waste gas, further increasing the efficiency of waste gas treatment for environmental protection projects. In addition, the waste gas treatment equipment used in the glue coating production line for gift box production also has the following issues.

[0003] Currently, the purification process for waste gas uses high-efficiency activated carbon to adsorb and filter harmful substances in the waste gas. However, once the high-efficiency activated carbon becomes saturated, its adsorption efficiency drops significantly. This necessitates that staff stop the equipment and go through complex procedures to ensure that no waste gas remains in the equipment before replacing the current high-efficiency activated carbon. To ensure the safety of staff during replacement, the frequent replacement of high-efficiency activated carbon in existing waste gas treatment equipment poses a risk of inhaling waste gas, increasing the operational risks. Furthermore, stopping the equipment to replace the high-efficiency activated carbon wastes a lot of time and affects the continuity of the waste gas treatment process. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention provides a waste gas treatment device for a gift box gluing production line.

[0005] The technical solution is as follows:

[0006] A waste gas treatment device for a gift box production glue coating line includes a main body of the device. The main body of the device includes an air inlet pipe connected to the glue coating operation room of the gift box production glue coating line and an air outlet pipe connected to the exhaust pipe. A diverter and a connector are respectively provided at one end of the air inlet pipe and the air outlet pipe, and a replacement mechanism is provided between the diverter and the connector.

[0007] The replacement mechanism has a second mating disc and a first mating disc that are rotatably engaged with the diverter and the connector, respectively. Between the first and second mating discs, there are multiple high-efficiency activated carbon filter components that are evenly distributed along the circumferential axis of the first mating disc. The high-efficiency activated carbon filter components are used to filter exhaust gas. Both the diverter and the connector have air inlets that are connected to any two high-efficiency activated carbon filter components. Two replacement ports are formed at the connection between the connector and the first mating disc. The two replacement ports are offset from the air inlets. Both replacement ports are detachably equipped with sealing caps.

[0008] Furthermore, a groove is formed at the end of the air inlet corresponding to the second mating plate, and a sealing ring is provided in the groove.

[0009] Furthermore, a base frame is connected between the air inlet pipe and the air outlet pipe, and a drive mechanism 140 is provided on the base frame. The drive mechanism 140 is used to drive the replacement mechanism to rotate. The single set stroke of the drive mechanism 140 is the same as the stroke between one high-efficiency activated carbon filter component and the adjacent high-efficiency activated carbon filter component.

[0010] Furthermore, the main body of the equipment is equipped with a control component, which includes a controller and a differential pressure sensor located in the outlet pipe. The differential pressure sensor is used to obtain the resistance value of the gas after passing through the high-efficiency activated carbon filter component and send it to the controller. The controller is used to control the drive mechanism 140 to work when the resistance value is less than the set threshold.

[0011] Furthermore, the flow divider has an inner cavity, and an air inlet connected to the air inlet pipe is formed in the inner cavity of the flow divider along the axis of the first mating disc. The air inlet area is smaller than the air outlet area of ​​the air supply port. A flow divider assembly is provided in the inner cavity of the flow divider. The flow divider assembly has a guide air component located at the air inlet. The guide air component is gradually tapered inward. Multiple air outlets are provided at equal intervals on the outer wall of the guide air component. Each air outlet is provided with a guide plate that is inclined towards the high-efficiency activated carbon filter assembly corresponding to the air supply port. The guide plate is used to guide the airflow towards the direction of the guide plate.

[0012] Furthermore, a baffle plate is provided between the air guide and the inner cavity. The baffle plate is arranged parallel to the air guide plate and is used to guide the airflow towards the direction of the air guide plate.

[0013] Furthermore, the high-efficiency activated carbon filter assembly has a through cavity inside, and a bracket is fixedly connected to the through cavity near the end of the diverter. A turbine is rotatably provided at the bracket, and an extension shaft extending towards the connector is fixedly connected to the turbine shaft. A packing cylinder is detachably provided between the through cavity and the extension shaft, and a fastener is detachably provided at the end of the extension shaft. The fastener is used to limit the axial movement of the packing cylinder.

[0014] Furthermore, the packing cylinder is provided with multiple rollers on the outer wall of one end near the connector, and an annular groove is formed on the inner wall of the through cavity corresponding to the connector to cooperate with the rollers. Multiple notches are formed on the inner wall of the annular groove corresponding to the multiple rollers on the side corresponding to the connector.

[0015] Furthermore, the stuffing cylinder has a filling cavity inside for installing filter material. One end of the filling cavity is fixedly provided with a filter screen, and the other end is detachably provided with a filter disc. The filter screen and the filter disc are provided with a sleeve that mates with the extension shaft at their axis.

[0016] Furthermore, a groove is formed on the outer wall of the extension shaft, and a insertion cavity is formed inside the sleeve, with a positioning block that mates with the groove forming inside the insertion cavity.

[0017] As described above, the beneficial effects of the waste gas treatment equipment for a gift box gluing production line of the present invention are as follows:

[0018] With its rotatable replacement mechanism, the saturated high-efficiency activated carbon filter components can be replaced during equipment operation, further reducing maintenance time. Replacement is done without stopping the machine, ensuring the continuity of the waste gas treatment process and improving the efficiency of continuous waste gas treatment in the coating production line. This also ensures zero waste gas leakage during the entire replacement process, avoiding the need for repeated machine shutdowns for activated carbon replacement, thus protecting the health and safety of operators and preventing environmental pollution. Furthermore, it reduces the frequency of activated carbon replacement and avoids the problem of internal waste gas leakage and environmental pollution that would occur when replacing activated carbon without disassembling the equipment.

[0019] By setting the drive mechanism 140 and control components, it can automatically determine whether to switch to a new high-efficiency activated carbon filter component, avoiding human error or delayed replacement. Compared with the traditional timed replacement or manual inspection method, this solution is based on the actual filtration effect for control, which is more accurate and efficient. At the same time, it improves the accuracy of replacement between the old and new high-efficiency activated carbon filter components, avoiding the situation where the gas inlet deviates from the corresponding high-efficiency activated carbon filter component, causing the high-efficiency activated carbon filter component to filter locally and affect the filtration effect.

[0020] By using a diversion component, the airflow is guided to both sides after entering the air guide, preventing the airflow from directly contacting the high-efficiency activated carbon filter. This effectively reduces turbulence and pressure loss in the exhaust gas flow, allowing the airflow to enter the filtration area more smoothly and improving the filtration effect. In addition, because the air guide is designed to taper inward, the airflow is compressed after entering the air guide. While dispersing the airflow, it retains the airflow velocity to drive the turbine, eliminating the need for additional power and saving space and energy.

[0021] By setting up a turbine and a packing cylinder, the turbine can drive the extension shaft to rotate when it rotates, thereby driving the packing cylinder on the extension shaft to rotate. This can keep the filter material in a dynamic dispersion state, greatly increasing the effective contact area with the exhaust gas. At the same time, the centrifugal force generated by the rotation can prevent particulate matter from accumulating on the surface of the packing, avoiding airway blockage and maintaining stable adsorption efficiency. Furthermore, the rotation allows the packing cylinder to dynamically contact the exhaust gas, avoiding local oversaturation. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0033] The embodiments provided by the present invention will be described in detail below:

[0034] like Figures 1 to 5As shown, a waste gas treatment device for a gift box production glue coating line includes a main body 100. The main body 100 includes an air inlet pipe 110 connected to the glue coating operation room of the gift box production glue coating line and an air outlet pipe 120 connected to the exhaust pipe. A diverter 210 and a connector 220 are respectively provided at opposite ends of the air inlet pipe 110 and the air outlet pipe 120. A replacement mechanism is provided between the diverter 210 and the connector 220, and the replacement mechanism is rotatably engaged with the diverter 210 and the connector 220.

[0035] The replacement mechanism has a second mating disc 320 and a first mating disc 310 that are rotatably engaged with the diverter 210 and the connector 220, respectively. Dynamic seals are provided between the diverter 210 and the second mating disc 320, as well as between the connector 220 and the first mating disc 310, to increase their sealing performance. Multiple high-efficiency activated carbon filter components 330 are evenly spaced along the circumferential direction of the first mating disc 310 between the first mating disc 310 and the second mating disc 320. These high-efficiency activated carbon filter components 330 are used to filter exhaust gas. Both the diverter 210 and the connector 220 have conveying mechanisms. The air inlet 340 at the diverter 210 is connected to the air inlet pipe 110, and the air inlet 340 at the connector 220 is connected to the air outlet pipe 120. The air inlet 340 is connected to two high-efficiency activated carbon filter components 330. The connector 220 and the first mating plate 310 form two replacement ports 360. The two replacement ports 360 are offset from the air inlet 340. Both replacement ports 360 are detachably equipped with sealing caps. The outer wall of the sealing cap is equipped with a sealing element. The sealing cap is snapped into the replacement port 360 by the sealing element.

[0036] The exhaust pipe is equipped with a suction fan, which is used to draw in the waste gas generated in the glue coating operation room of the gift box production glue coating line, and then discharge it after being treated by this equipment. This is existing technology and will not be described in detail here.

[0037] Among them, the high-efficiency activated carbon filter component 330 has heat dissipation fins on its outer wall, which can dissipate heat from the exhaust gas and heat generated by the rotation of the turbine 520, ensuring the normal operation of the turbine 520 for a long time.

[0038] It should be noted that the number of high-efficiency activated carbon filter components 330 is an even positive number, so that when the air inlet 340 rotates to replace the high-efficiency activated carbon filter components 330, all high-efficiency activated carbon filter components 330 can be replaced accordingly without any omissions.

[0039] Specifically, the air inlet pipe 110 of this equipment is connected to the glue coating operation chamber of the gift box production glue coating line. The suction fan works to draw in the waste gas generated in the glue coating operation chamber of the gift box production glue coating line, which is then discharged after being treated by this equipment.

[0040] When the high-efficiency activated carbon filter element 330 becomes saturated after prolonged use and needs to be replaced, the second mating disc 320 at the replacement mechanism is manually rotated to move the high-efficiency activated carbon filter element 330 on the second mating disc 320 to the position of the adjacent high-efficiency activated carbon filter element 330, that is, to the replacement port 360 that is misaligned with the diverter 210. After the above is completed, the operator can replace the saturated high-efficiency activated carbon filter element 330 during equipment operation by removing the sealing cover. Alternatively, multiple high-efficiency activated carbon filter elements 330 can be replaced at the same time after they have all been used up and become saturated, thereby reducing maintenance time. At the same time, there is no need to stop the machine for replacement, ensuring the continuity of the waste gas treatment process and improving the efficiency of continuous waste gas treatment in the coating production line.

[0041] In addition, the replacement port 360 is normally closed, that is, the sealing cover is always inside the replacement port 360. When the high-efficiency activated carbon filter component 330 is replaced, the sealing cover is opened for replacement. After replacement, the sealing cover is installed in the replacement port 360 to ensure that the replacement port 360 is in a closed state and to ensure that the high-efficiency activated carbon filter component 330 is always in a dry and sealed state.

[0042] refer to Figure 3 A groove is formed at the corresponding end of the air inlet 340 and the second mating plate 320, which is set along the outer shape of the air inlet 340. A sealing ring 350 is installed in the groove, and the outer ring of the sealing ring 350 protrudes out of the groove.

[0043] Among them, a sealing element is installed between the diverter 210 and the second mating plate 320, the connector 220 and the first mating plate 310.

[0044] It should be noted that the gas inlet 340 always corresponds to two high-efficiency activated carbon filter components 330. The sealing ring 350 ensures that no exhaust gas leaks during the replacement of the high-efficiency activated carbon filter components 330, and also ensures that no exhaust gas leaks during the treatment process when the high-efficiency activated carbon filter components 330 are covered and sealed by the sealing ring 350. This achieves zero exhaust gas leakage during the entire replacement process of the high-efficiency activated carbon filter components 330, protects the health and safety of operators, and avoids environmental pollution.

[0045] A base frame 130 is connected between the air inlet pipe 110 and the air outlet pipe 120. A drive mechanism 140 is mounted on the base frame 130. The drive mechanism 140 is used to drive the replacement mechanism to rotate. The single set stroke of the drive mechanism 140 is the same as the stroke between one high-efficiency activated carbon filter component 330 and the adjacent high-efficiency activated carbon filter component 330.

[0046] It should be noted that the drive mechanism 140 can be electrically driven to rotate the replacement mechanism, eliminating the need for manual rotation. Compared to manual rotation, by setting the single-stroke travel of the drive mechanism 140 to be the same as the travel between one high-efficiency activated carbon filter component 330 and the adjacent high-efficiency activated carbon filter component 330, the accuracy of replacing the old and new high-efficiency activated carbon filter components 330 is improved. This avoids the situation where the air inlet 340 deviates from the corresponding high-efficiency activated carbon filter component 330, causing the high-efficiency activated carbon filter component 330 to filter only partially, thus affecting the filtration effect.

[0047] A control component is installed at the main body 100 of the equipment. The control component includes a controller and a differential pressure sensor located in the outlet pipe 120. The differential pressure sensor is used to obtain the resistance value of the gas after passing through the high-efficiency activated carbon filter component 330 and send it to the controller. The controller is used to control the drive mechanism 140 to work when the resistance value is less than the set threshold.

[0048] It should be noted that the above is the existing structure, in which the drive mechanism 140 can drive the replacement mechanism to rotate, and the control component is used to monitor the resistance value of the high-efficiency activated carbon filter component 330. When the resistance value is less than the set threshold, the drive mechanism 140 is controlled to work, and when the resistance value is greater than or equal to the set threshold, no action is taken.

[0049] Specifically, after prolonged use of the high-efficiency activated carbon filter component 330, its airflow decreases (when the high-efficiency activated carbon filter component 330 is saturated with adsorption, the resistance value will significantly decrease). Due to the reduced airflow, the pressure sensor detects that the airflow resistance value is less than the set threshold and sends an electrical signal to the controller. Upon receiving the signal, the controller sends a start signal to the drive mechanism 140, controlling the drive mechanism 140 to rotate the high-efficiency activated carbon filter component 330 on the second mating disc 320 at the drive replacement mechanism to the position of the adjacent high-efficiency activated carbon filter component 330, that is, at the replacement port 360 that is misaligned with the diverter 210. This allows for automatic determination of whether to switch to a new high-efficiency activated carbon filter component 330, avoiding human error or delayed replacement. Compared with traditional timed replacement or manual inspection methods, this solution controls based on the actual filtration effect, making it more precise and efficient, avoiding waste caused by premature replacement, improving the utilization rate of consumables such as activated carbon, and saving manpower.

[0050] If the resistance value is greater than or equal to the set threshold, no action is taken.

[0051] In addition, the control component may also have an alarm module. When the differential pressure fluctuation is abnormal, the alarm module sends a signal to the controller, and the controller sends a prompt message to the terminal to remind maintenance personnel to check the equipment status and prevent the fault from escalating. This is existing technology and will not be elaborated on here.

[0052] like Figures 2-4As shown, the flow divider 210 has an inner cavity, and an air inlet 410 is formed in the inner cavity, which is arranged along the axis of the first mating plate 310 and communicates with the air inlet pipe 110. The air inlet area of ​​the air inlet 410 is smaller than the air outlet area of ​​the air supply port 340. A flow divider assembly 230 is fixedly connected in the inner cavity of the flow divider 210. The flow divider assembly 230 has a guide 430 at the air inlet 410. The guide 430 is generally tapered inward. Multiple air outlets 440 are fixedly connected at equal intervals on the outer wall of the guide 430. Each air outlet 440 is provided with a guide plate 450 that is inclined towards the high-efficiency activated carbon filter assembly 330 corresponding to the air supply port 340. The guide plate 450 is used to guide the airflow towards the direction of the guide plate 450.

[0053] It should be noted that after the airflow enters the air guide 430, it is guided to both sides and dispersed, avoiding direct contact between the airflow and the high-efficiency activated carbon filter component 330. This can effectively reduce the turbulence and pressure loss of the exhaust gas flow, allowing the airflow to enter the filtration area more smoothly and improving the filtration effect. In turn, it can buffer the exhaust gas in the diversion component 210, avoiding the problem of exhaust gas passing through too quickly and not being properly filtered due to direct connection between the activated carbon and the air inlet.

[0054] A baffle plate 420 is fixedly connected between the air guide 430 and the inner cavity. The baffle plate 420 is arranged parallel to the air guide plate 450 and is used to guide the airflow to the direction of the air guide plate 450.

[0055] Understandably, the guiding design of the baffle plate 420 allows the airflow dispersed by the air guide component 430 to flow more effectively to the high-efficiency activated carbon filter component 330.

[0056] Specifically, after the airflow enters the air inlet 410, it is dispersed to both sides by the air outlet 440, and then guided to the corresponding high-efficiency activated carbon filter component 330 by the air guide plate 450. This disperses the airflow and slows down the airflow speed, allowing the exhaust gas to fully contact the high-efficiency activated carbon filter component 330 and improve the filtration effect.

[0057] like Figure 2 and Figures 5-7 As shown, a through cavity is formed inside the high-efficiency activated carbon filter assembly 330. A bracket 510 is fixedly connected to the through cavity of the high-efficiency activated carbon filter assembly 330 near the end of the diverter 210. A turbine 520 is rotatably provided in the middle of the bracket 510. An extension shaft 530 extending towards the connector 220 is fixedly connected to the shaft of the turbine 520. A packing cylinder 540 is detachably provided between the through cavity of the high-efficiency activated carbon filter assembly 330 and the extension shaft 530. A fastener 550 is detachably provided at the end of the extension shaft 530 away from the shaft of the turbine 520. The fastener 550 is used to limit the axial movement of the packing cylinder 540.

[0058] It should be noted that when the turbine 520 rotates, it can drive the extension shaft 530 to rotate, thereby driving the packing cylinder 540 on the extension shaft 530 to rotate. This can keep the filter material in a dynamic dispersion state, greatly increasing the effective contact area with the exhaust gas. At the same time, the force generated by the rotation can prevent particulate matter from accumulating on the surface of the packing, avoid air passage blockage, maintain stable adsorption efficiency, and allow the packing cylinder 540 to dynamically contact the exhaust gas as it rotates, avoiding local oversaturation.

[0059] Specifically, during maintenance and replacement, simply pull the stuffing box 540 out of the extension shaft 530 and replace the stuffing box 540, which reduces the difficulty of replacement.

[0060] Multiple rollers 740 are provided on the outer wall of the packing cylinder 540 near the connector 220. An annular groove 610 is formed on the inner wall of the through cavity of the high-efficiency activated carbon filter assembly 330 corresponding to the connector 220, which cooperates with the rollers 740. Multiple notches 620 corresponding to the multiple rollers 740 are formed on the inner wall of the annular groove 610 corresponding to the connector 220, and the multiple notches 620 are interconnected with the annular groove 610.

[0061] It should be noted that the roller 740 rolls within the annular groove 610, replacing the rotational friction between the packing cylinder 540 and the through cavity of the high-efficiency activated carbon filter assembly 330 with rolling friction between the roller 740 and the annular groove 610. This reduces the power required to drive the turbine 520 and allows for positioning of the packing cylinder 540, facilitating subsequent maintenance and replacement. The turbine-driven packing cylinder structure enables dynamic adsorption and convenient replacement of the filter material, significantly improving exhaust gas purification efficiency and maintenance convenience.

[0062] In addition, since the air guide 430 is designed to taper inward, the airflow is compressed after entering the air guide 430. While dispersing the airflow, the airflow velocity is maintained to drive the turbine 520 without the need for additional power, thus saving space and energy.

[0063] The stuffing cylinder 540 has a filling cavity for installing filter material. A filter screen part 710 is fixedly provided at one end of the filling cavity, and a filter disc 720 is detachably provided at the other end. A sleeve 730 that mates with the extension shaft 530 is fixedly connected at the axis of the filter screen part 710 and the filter disc 720.

[0064] A groove is formed on the outer wall of the extension shaft 530, and a insertion cavity is formed inside the sleeve 730. A positioning block that mates with the groove is formed inside the insertion cavity.

[0065] It should be noted that the filter material can be activated carbon. Through the cooperation of the groove at the extension shaft 530 and the positioning block at the sleeve 730, when the turbine 520 rotates and drives the extension shaft 530, it can drive the packing cylinder 540 on the extension shaft 530 to rotate synchronously, thereby realizing spin-type dynamic filtration.

[0066] Specifically, when replacing the packing cylinder 540, the operator removes the sealing cap, then takes out the fastener 550. By opening the filter disc 720, the filter material in the filling chamber can be replaced. If it is activated carbon, it can be reused after cleaning, saving material costs. When installing the packing cylinder 540, the sleeve 730 is inserted into the extension shaft 530. At the same time, by aligning the roller 740 at one end of the packing cylinder 540 with the notch 620, the roller 740 is pushed into the annular groove 610. Then, the fastener 550 is reinstalled at the end of the extension shaft 530 to limit the packing cylinder 540. Finally, the sealing cap is re-snapped into the replacement port 360 to ensure that the replacement port 360 is in a closed state, ensuring that the high-efficiency activated carbon filter assembly 330 is always in a dry and sealed state. The operation is simple and can quickly replace the saturated packing cylinder 540 without stopping the machine, ensuring the continuity of the exhaust gas treatment process and improving the efficiency of continuous exhaust gas treatment in the coating production line.
