Description

Technical Field

[0001] The invention belongs to the technical field of waste purification and recycling, and in particular relates to a waste purification and recycling device applied to green printing and packaging. Background Art

[0002] Green printing and packaging focuses on the use of environmentally friendly materials, processes and technologies in the printing and packaging process to reduce damage to the ecological environment and excessive consumption of resources. However, the green printing and packaging process will inevitably produce various types of waste, among which gaseous waste is a more difficult type. These gaseous wastes mainly come from the volatilization of inks in the printing process, the use of organic solvents, and waste gas generated during the drying process. If these gaseous wastes are not effectively treated and directly discharged into the atmosphere, they will cause serious harm. Water, as a common solvent, can dissolve some harmful substances in gaseous wastes. The method of spraying gaseous waste into water for purification and recovery has the advantages of relatively simple equipment, low cost, and easy operation.

[0003] For example, in the flue gas purification device of the waste recycling granulator disclosed in the patent with publication number CN211411468U in the prior art, after the flue gas comes out of the water, it enters the processing barrel, and the activated carbon particles can filter the flue gas and absorb harmful substances and fine particles in the flue gas.

[0004] The problems with the existing technology are: the lack of a real-time monitoring mechanism, the inability to dynamically detect the concentration of harmful gases during the transportation process, and the inability of the device to make targeted adjustments based on the difference in gas concentration. When the concentration of harmful gases is high, the gas flow path in the water tank is single and the contact with the purification medium is insufficient, resulting in a significant reduction in the purification effect. When the gas concentration is low, the purification time cannot be shortened accordingly, resulting in low efficiency. Summary of the Invention

[0005] In response to the problems existing in the prior art, the present invention provides a waste purification and recycling device applied to green printing and packaging, which has the advantages of good purification effect, high efficiency and more precise control. It solves the problem that the existing device cannot be adjusted in a targeted manner according to the difference in gas concentration, resulting in poor purification effect and low efficiency.

[0006] The present invention is implemented as follows: a waste purification and recycling device for green printing and packaging, including a waste box, a fan connected to one side of the waste box, an air duct fixedly connected to the output end of the fan, one end of the air duct connected to a water tank, an activated carbon filter device provided at the end of the water tank away from the air duct, a gas concentration detector provided on the air duct, and several adjustment mechanisms equidistantly provided in the water tank.

[0007] As a preferred embodiment of the present invention, a top cover is fixedly installed on the top of the water tank, a sealing cover is fixedly connected to the lower surface of the top cover, and the sealing cover is sealed to the inner wall of the upper end of the water tank.

[0008] As a preferred embodiment of the present invention, a water inlet pipe is provided through the top cover and the sealing cover, a water outlet pipe is provided at one end of the water tank away from the air duct, and valves are provided on both the water inlet pipe and the water outlet pipe.

[0009] As a preferred embodiment of the present invention, a plurality of sealing sleeves are fixedly installed between the top cover and the sealing cover.

[0010] As a preferred embodiment of the present invention, the adjustment mechanism includes a rotating shaft, the rotating shaft is rotatably installed in the water tank, and a baffle is fixedly installed on the rotating shaft.

[0011] As a preferred embodiment of the present invention, a ventilation gap is provided between one end of the baffle and the side wall of the water tank, a sealing strip is fixedly connected to the other end of the baffle, baffles are fixedly connected to both inner side walls of the water tank, and the sealing strips abut against the corresponding baffles.

[0012] As a preferred embodiment of the present invention, a worm gear is fixedly connected to the upper end of the rotating shaft, a mounting seat is provided on one side of the worm gear, and the mounting seat is fixedly installed on the upper surface of the top cover.

[0013] As a preferred embodiment of the present invention, a worm is rotatably mounted on the mounting seat, the worm is meshedly connected to the worm wheel, and one end of the worm is fixedly connected to a driving member.

[0014] As a preferred embodiment of the present invention, the driving member is configured as a motor.

[0015] As a preferred embodiment of the present invention, except for the baffle close to the air duct, the other baffles are provided with a filter plate on the side away from the sealing strip; when the baffles are side by side in a line, the sealing strip can fit on the adjacent filter plates, and the baffle close to the air duct fits on the inner wall of the water tank; the water inlet of the water inlet pipe, the drain outlet of the water outlet pipe, the air inlet of the air duct and the exhaust outlet of the activated carbon filter device are all located on the same side of the water tank.

[0016] As a preferred embodiment of the present invention, an air cavity is provided inside the sealing strip; airbag strips are provided on the upper side and the lower side of the baffle, and the airbag strips are in communication with the air cavity.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is equipped with a gas concentration detector to detect the concentration of harmful gases passing through the air duct in real time, so as to adjust the state of the baffle in the water tank accordingly, thereby adjusting the flow path and speed of the waste in the water tank.

[0018] 2. When the concentration of harmful gases in the waste is high, the present invention makes the baffle perpendicular to the side wall of the water tank, and one end of the baffle is against the baffle through a sealing strip to achieve sealing, and a ventilation gap is left between the other end and the side wall, so that the waste moves in an S-shaped route in the water tank, so that the waste is in full contact with water, thereby improving the purification effect. When the concentration is low, the baffle is parallel to the side wall of the water tank to improve the purification efficiency. When the concentration is medium, the baffle positions are staggered to achieve precise control of the purification process.

[0019] 3. This device uses a motor as a driving component to drive the shaft to rotate continuously, which can stir the water and increase the contact area between the exhaust gas and water, such as turning large bubbles into small bubbles, thereby improving the purification effect. Even when the tank is not filled with water, the shaking of the water can make the upper exhaust gas dissolve into the water again. At the same time, except for the baffles close to the air duct, the other baffles are equipped with filter plates on the side away from the sealing strip. When the baffles are side by side, the sealing strip can fit the adjacent filter plates, and the baffles close to the air duct fit the inner wall of the water tank. The water inlet of the water inlet pipe, the drain outlet of the water outlet pipe, the air inlet of the air duct and the exhaust outlet of the activated carbon filter device are all located on the same side of the water tank. When gas passes through the filter plate, large bubbles can be divided into small bubbles, further improving the purification efficiency. In addition, through the cooperation of the baffle, sealing strip and filter plate, the water tank can be divided into two chambers, blocking the filter plate to achieve sealing. Only half of the water tank can be used, and the other half is free of water, achieving the purpose of water saving. It is suitable for situations where frequent water changes are required. The worm gear and worm can form a self-locking function to prevent the baffle from rotating under the pressure of water and destroying the sealing.

[0020] 4. The sealing strip has an internal air cavity, and airbag strips are installed on both the upper and lower sides of the baffle to connect with the air cavity. This configuration has two advantages. On the one hand, when the sealing strip is pressed against the filter plate, the gas in the air cavity can squeeze the sealing strip, making it fit the filter plate more fully, significantly improving the sealing effect. On the other hand, the gas in the air cavity enters the airbag strip, which can effectively seal the upper and lower sides of the baffle, further ensuring the sealing and performance of the device.

[0023] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0024] The structure of the present invention is described in detail below with reference to the accompanying drawings.

[0025] Example 1 See Figures 1 to 5 An embodiment of the present invention provides a waste purification and recycling device for green printing and packaging, including a waste box 1, a fan 4 connected to one side of the waste box 1, an output end of the fan 4 fixedly connected to an air duct 41, one end of the air duct 41 is connected to a water tank 5, an activated carbon filter device 2 is provided at the end of the water tank 5 away from the air duct 41, a gas concentration detector 6 is provided on the air duct 41, and a plurality of adjustment mechanisms 3 are equidistantly provided in the water tank 5.

[0026] In this application, the waste box 1 is used to store gaseous waste generated by green printing packaging. The waste spray is extracted from the waste box 1 by the fan 4 and transported to the water tank 5 through the air duct 41, so that the harmful components in the waste are dissolved in the water, thereby achieving preliminary purification of the waste, and then further purified by the activated carbon filter device 2. Among them, the activated carbon filter device 2 adopts the activated carbon filter structure disclosed in the patent with publication number CN211411468U in the prior art to achieve multi-stage purification of the waste, and then the purified gas is recycled.

[0027] The gas concentration detector 6 can detect the concentration of harmful gases passing through the air duct 41 in real time, so as to adjust the flow path and speed of the waste in the water tank 5 accordingly through the regulating mechanism 3 .

[0028] A top cover 53 is fixedly installed on the top of the water tank 5 , and a sealing cover 54 is fixedly connected to the lower surface of the top cover 53 . The sealing cover 54 is sealed to the inner wall of the upper end of the water tank 5 .

[0029] The top cover 53 serves to seal the water tank 5, and the sealing cover 54 further enhances the sealing of the water tank 5, preventing gas from escaping from the top of the water tank 5 into the surrounding environment, thereby ensuring the safety of the working environment and ensuring that the purification process is carried out in a relatively closed environment.

[0030] A water inlet pipe 51 is provided through the top cover 53 and the sealing cover 54 . A water outlet pipe 52 is provided at one end of the water tank 5 away from the air duct 41 . Valves are provided on both the water inlet pipe 51 and the water outlet pipe 52 .

[0031] By opening the valve on the water inlet pipe 51, water can be added to the water tank 5, and by opening the valve on the water outlet pipe 52, the water in the water tank 5 can be discharged, so as to facilitate replacement of new purified water.

[0032] Several sealing sleeves 55 are fixedly installed between the top cover 53 and the sealing cover 54. The rotating shaft 31, the water inlet pipe 51, and the bottom of the activated carbon filter device 2 are all installed in the corresponding sealing sleeves 55. The sealing sleeves 55 can improve the sealing between the corresponding components and the top cover 53 and the sealing cover 54, effectively preventing gas leakage.

[0033] The adjusting mechanism 3 includes a rotating shaft 31, which is rotatably installed in the water tank 5. A baffle 32 is fixedly installed on the rotating shaft 31, and a ventilation gap is provided between one end of the baffle 32 and the side wall of the water tank 5. The other end of the baffle 32 is fixedly connected to a sealing strip 33. Baffles 56 are fixedly connected to both inner side walls of the water tank 5, and the sealing strips 33 abut against the corresponding baffles 56. A worm gear 34 is fixedly connected to the upper end of the rotating shaft 31, and a mounting seat 37 is provided on one side of the worm gear 34. The mounting seat 37 is fixedly installed on the upper surface of the top cover 53. A worm 35 is rotatably installed on the mounting seat 37, and the worm 35 is meshed with the worm gear 34. One end of the worm 35 is fixedly connected to a driving member 36.

[0034] The upper and lower ends of the baffle 32 are rotatably connected to the sealing cover 54 and the bottom inner wall of the water tank 5 respectively. The rotating shaft 31 is set in the middle of the baffle 32. The baffle 32 can be set perpendicular to the length direction of the water tank 5, which is suitable for situations where the concentration of harmful gases in the waste is high. It can also be set in parallel, which is suitable for situations where the concentration of harmful gases in the waste is low. When set vertically, one end of the baffle 32 is in contact with the baffle 56 through the sealing strip 33, and a ventilation gap is left at the other end. Several baffles 56 are set in reverse order. In this state, the path of the waste is S-shaped, which can extend the contact time between the waste and water within the limited space of the water tank 5, so that the waste is fully in contact with water, thereby improving the purification effect. When set in parallel, the contact time between the waste and water is relatively short, which can improve the purification treatment efficiency. The baffles 32 can also be staggered according to the concentration range to achieve precise control of the purification treatment.

[0035] The setting direction of the baffle 32 is controlled by the driving member 36 (which can be set as a handle or a motor). Specifically, the driving member 36 is rotated to drive the worm 35 and the worm wheel 34 to rotate, so that the rotating shaft 31 drives the baffle 32 to rotate until the sealing strip 33 is tightly abutted against the baffle 56. During the specific setting, an indicator arrow can be set at the upper end of the rotating shaft 31, and the arrow points in the direction of the sealing strip 33, so that the staff can understand the movement of the sealing strip 33 inside the water tank 5.

[0036] Example 2 See Figures 1-6 The drive element 36 is configured as a motor (not shown). Under normal circumstances, the purifier needs to be fully filled with water before use; otherwise, the exhaust gas quickly rises above the water surface, reducing purification effectiveness. Driven by the motor, the rotating shaft 31 continuously rotates, agitating the water and increasing the contact area between the exhaust gas and the water, for example, reducing large bubbles to smaller ones. Furthermore, when the purifier is not fully filled with water, the shaking of the water can also dissolve the exhaust gas from the upper layer back into the water.

[0037] Furthermore, except for the baffle 32 close to the air duct 41, the other baffles 32 are provided with a filter plate 7 on the side away from the sealing strip 33; when the baffles 32 are arranged side by side in a line, the sealing strip 33 can fit on the adjacent filter plates 7, and the baffle 32 close to the air duct 41 fits on the inner wall of the water tank 5; the water inlet of the water inlet pipe 51, the drain outlet of the water outlet pipe 52, the air inlet of the air duct 41 and the exhaust outlet of the activated carbon filter device 2 are all located on the same side of the water tank 5.

[0038] When gas passes through filter plates 7, large bubbles are split into smaller ones, improving purification efficiency. Baffles 32 are arranged side by side in a line, and sealing strips 33 are attached to adjacent filter plates 7, dividing the water tank 5 into two chambers. Sealing strips 33 block the filter plates 7 to achieve a seal, allowing only half of the water tank 5 to be used, leaving the other half empty, thus conserving water. This approach is ideal for frequent water changes. Furthermore, the worm gear 34 and worm 35 work together to create a self-locking mechanism, preventing the baffles 32 from rotating under water pressure and losing their seal.

[0039] Furthermore, the sealing strip 33 has an internal air cavity. Airbag strips 8 are located on both the upper and lower sides of the baffle 32, communicating with the air cavity. This arrangement allows the sealing strip 33 to be pressed against the filter plate 7, with the gas in the air cavity squeezing the sealing strip 33, ensuring a full fit and enhancing the sealing effect. Furthermore, the gas in the air cavity enters the airbag strips 8, effectively sealing the upper and lower sides of the baffle 32.

[0040] The specific implementation is as follows: The device is installed as follows: Install the motor (drive element 36) in a suitable position, ensuring it can drive the rotating shaft 31 to rotate and that the motor's control circuitry is properly connected, enabling opening and closing operations. Install the rotating shaft 31 in the water tank 5 and ensure it rotates freely. Install the baffle 32, filter plate 7, sealing strip 33, worm gear 34, and worm 35 components within the water tank 5 according to the design requirements. Except for the baffle 32 near the air duct 41, install the filter plate 7 on the side of the other baffles 32 away from the sealing strip 33. Install the water inlet of the water inlet pipe 51, the drain outlet of the water outlet pipe 52, the air inlet of the air duct 41, and the exhaust outlet of the activated carbon filter device 2 on the same side of the water tank 5, ensuring that all pipes are securely connected and leak-free. Provide an air cavity within the sealing strip 33, and install airbag strips 8 on the upper and lower sides of the baffle 32, connecting to the air cavity.

[0041] The usage is as follows: During normal use, water is first filled into the water tank 5 through the water inlet pipe 51. The motor is then turned on, driving the rotating shaft 31 to rotate and begin agitating the water. Exhaust gas enters the water tank 5 through the air inlet of the air duct 41, where it comes into contact with the water for initial purification. As the gas passes through the filter plate 7, it is divided into small bubbles, further enhancing the purification effect. To conserve water and use only half of the water tank 5, the baffles 32 are adjusted to a straight-line, side-by-side position, so that the sealing strips 33 conform to the adjacent filter plates 7 and the inner wall of the water tank, dividing the water tank into two chambers. At this point, water is added to one of the chambers through the water inlet pipe 51 to the appropriate level to purify the exhaust gas. During this process, the worm gear 34 and worm 35 automatically engage to form a self-locking mechanism, preventing the baffle 32 from rotating due to water pressure. At the same time, the gas in the air cavity of the sealing strip 33 will squeeze the sealing strip according to actual conditions, making it fit the filter plate 7 better, and part of the gas enters the airbag strip 8 to achieve sealing on both sides of the baffle 32.

[0042] Working principle of the present invention: When in use, the waste generated by green printing packaging is stored in the waste box 1, and the fan 4 is started to extract the waste in the waste box 1 and transport it to the water tank 5 through the air duct 41. Before the waste enters the water tank 5, the gas concentration detector 6 will detect the concentration. If the concentration of harmful gases in the waste is detected to be high, the baffle 32 is set perpendicular to the length direction of the water tank 5. When the concentration is in the middle, the positions of the baffles 32 are staggered. When the concentration is low, they are set in parallel, so as to achieve precise control of the waste purification process. During adjustment, the worm 35 and the worm gear 34 are driven to rotate by the rotating drive member 36, so that the rotating shaft 31 drives the baffle 32 to rotate accordingly to achieve adjustment. In the process of the waste moving inside the water tank 5, the harmful components are dissolved in the water, thereby achieving preliminary purification of the waste, and then moving to the activated carbon filter device 2 at the other end of the water tank 5, and further purified by the activated carbon filter device 2, and finally the purified gas is recycled.

[0043] Furthermore, it also includes: Exhaust gas and water contact purification: The primary purpose of this device is to purify exhaust gas. For normal use, the water tank 5 must be filled with water. A motor (drive element 36) drives the rotating shaft 31 to rotate continuously, thereby agitating the water in the water tank 5. The rotating water flow increases the contact area between the exhaust gas and the water. For example, it reduces large bubbles entering the water to smaller ones, allowing for more complete contact between the exhaust gas and the water, thereby enhancing the purification effect. Even if the water tank is not completely filled, the agitation of the water can re-dissolve the exhaust gas from the upper layer into the water, allowing the purification process to continue.

[0044] Filter plate refines bubbles: Except for the baffle 32 near the air duct 41, the other baffles 32 are equipped with filter plates 7 on the side away from the sealing strip 33. When the exhaust gas passes through the filter plate 7, the filter plate 7 will split large bubbles into small bubbles, further increasing the contact area between the exhaust gas and water, thereby improving purification efficiency.

[0045] Water tank chamber separation and water conservation: When baffles 32 are aligned, the sealing strips 33 can adhere to adjacent filter plates 7, and the baffle 32 near the air duct 41 adheres to the inner wall of the water tank 5, thus dividing the water tank 5 into two chambers. In this case, only one half of the water tank 5 can be used to hold water for exhaust gas purification, while the other half remains empty, achieving water conservation. This is particularly suitable for applications where frequent water changes are required.

[0046] Self-locking ensures sealing: When the water tank is divided into two chambers, the worm wheel 34 and the worm 35 form a self-locking mechanism to prevent the baffle 32 from rotating under the pressure of water, thereby ensuring the sealing of the separated chambers and preventing water from flowing from one chamber into the other, affecting the purification effect and water-saving function.

[0047] The sealing structure works as follows: An air cavity is defined within the sealing strip 33, and airbag strips 8 are located on both the upper and lower sides of the baffle 32, communicating with the air cavity. When the sealing strip 33 is pressed against the filter plate 7, the gas in the air cavity compresses the sealing strip 33, forcing it to adhere more fully to the filter plate 7 and improving the sealing effect. Simultaneously, the gas in the air cavity enters the airbag strips 8, sealing the upper and lower sides of the baffle 32 and further enhancing the sealing performance of the entire device.

[0048] In summary, this waste purification and recycling device applied to green printing and packaging can flexibly adjust the flow path and speed of the waste in the water tank 5 according to the different concentrations of harmful gases in the waste by setting the adjustment mechanism 3, thereby improving the purification effect and processing efficiency.
