[0030] The structure of the present application will be described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0033] In the present application, the waste box 1 is used to store gaseous waste generated by green printing packaging, the waste is sprayed out of the waste box 1 by the fan 4, is transported into the water tank 5 through the air pipe 41, and the harmful components in the waste are dissolved in water to realize preliminary purification of the waste, and the waste is further purified through the activated carbon filter device 2, wherein the activated carbon filter device 2 adopts the activated carbon filter structure disclosed in the patent with the publication number CN211411468U in the prior art to realize multi-stage purification of the waste, and the purified gas is recycled.

[0034] The gas concentration detector 6 can detect the harmful gas concentration passing through the air pipe 41 in real time, so as to correspondingly adjust the flow path and speed of the waste in the water tank 5 through the adjusting mechanism 3.

[0035] The top cover 53 is fixedly installed at the top end of the water tank 5, the sealing cover 54 is fixedly connected to the lower surface of the top cover 53, and the sealing cover 54 is sealingly connected with the upper end inner wall of the water tank 5.

[0036] The top cover 53 plays a role of closing the water tank 5, and the sealing cover 54 further enhances the sealing of the water tank 5, avoids gas from escaping from the top of the water tank 5 to the surrounding environment, guarantees the safety of the working environment, and also guarantees that the purification process is carried out in a relatively closed environment.

[0037] The water inlet pipe 51 is provided through the top cover 53 and the sealing cover 54, and the water outlet pipe 52 is provided at the end of the water tank 5 away from the air pipe 41. The water inlet pipe 51 and the water outlet pipe 52 are both provided with valves.

[0038] By opening the valve on the water inlet pipe 51, water can be injected into the water tank 5, and by opening the valve on the water outlet pipe 52, water in the water tank 5 can be discharged, which is convenient for replacing new water for purification.

[0039] A plurality of 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, which can improve the sealing between the corresponding components and the top cover 53 and the sealing cover 54, effectively avoiding gas leakage.

[0040] The adjusting mechanism 3 includes a rotating shaft 31 rotatably installed in the water tank 5, a baffle 32 fixedly installed on the rotating shaft 31, a sealing strip 33 fixedly connected to one end of the baffle 32, a plurality of blocking strips 56 fixedly connected to the inner side walls of the water tank 5, the sealing strip 33 abutting against the corresponding blocking strip 56, a worm gear 34 fixedly connected to the upper end of the rotating shaft 31, an installation seat 37 provided on one side of the worm gear 34 and fixedly installed on the upper surface of the top cover 53, a worm shaft 35 rotatably installed on the installation seat 37 and meshingly connected with the worm gear 34, and a driving member 36 fixedly connected to one end of the worm shaft 35.

[0041] 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 arranged at the middle part of the baffle 32, the baffle 32 can be arranged perpendicular to the length direction of the water tank 5, which is suitable for the case that the concentration of harmful gas in the waste material is relatively high, or can be arranged in parallel, which is suitable for the case that the concentration of harmful gas in the waste material is relatively low, when arranged perpendicularly, one end of the baffle 32 abuts against the blocking strip 56 through the sealing strip 33, and the other end has a ventilation gap, a plurality of blocking strips 56 are arranged in reverse order, in this state, the path of the waste material is S-shaped, which can prolong the contact time of the waste material with water in the limited space of the water tank 5, so that the waste material is fully contacted with water, and the purification effect is improved, when arranged in parallel, the contact time of the waste material with water is relatively short, which can improve the purification efficiency, and the baffle 32 can also be arranged staggered according to the concentration range, to realize precise control of the purification treatment.

[0042] The setting direction of the baffle 32 is controlled by the driving member 36 (which can be a handle or a motor), specifically, by rotating the driving member 36 to drive the worm 35 and the worm wheel 34 to rotate, so as to drive the rotating shaft 31 to rotate the baffle 32 until the sealing strip 33 is tightly abutted against the baffle 56. In a specific setting, an indicating arrow can be arranged on the upper end of the rotating shaft 31, which points to the direction of the sealing strip 33, so as to enable the staff to master the movement of the sealing strip 33 in the water tank 5.

[0043] Embodiment 2

[0044] Referring to Figures 1-6 The driving member 36 is arranged as a motor (not shown in the figure). Normally, the water tank 5 needs to be filled with water before use, otherwise the exhaust gas will quickly rise above the water surface, reducing the purification effect. By means of motor driving, the rotating shaft 31 is continuously rotated to agitate the water, increase the contact area between the exhaust gas and the water, for example, to change the large bubbles into small bubbles. Moreover, in the case of not being filled with water, the exhaust gas in the upper layer of the water tank 5 can also be re-dissolved into the water through the shaking of the water.

[0045] Further, in addition to the baffle 32 close to the air pipe 41, the other baffles 32 are provided with filter plates 7 away from the side of the sealing strip 33. When the baffles 32 are in a straight line and side by side, the sealing strip 33 can be attached to the adjacent filter plate 7, and the baffle 32 close to the air pipe 41 is attached to the inner wall of the water tank 5. The water inlet of the water inlet pipe 51, the water outlet of the water outlet pipe 52, the air inlet of the air pipe 41 and the exhaust port of the activated carbon filter device 2 are all located on the same side of the water tank 5.

[0046] When the gas passes through the filter plate 7, it can divide the large bubbles into small bubbles, improving the purification efficiency. When the baffles 32 are in a straight line and side by side, and the sealing strip 33 is attached to the adjacent filter plate 7, the water tank 5 can be divided into two chambers. The sealing strip 33 blocks the filter plate 7 to achieve sealing, so that only half of the water tank 5 can be used, and the other half is without water, achieving water saving. This situation is suitable for the case where water needs to be frequently replaced. Moreover, in this case, through the cooperation of the worm wheel 34 and the worm 35, self-locking can be formed to prevent the baffle 32 from rotating under the pressure of the water and losing the sealing property.

[0047] Further, the sealing strip 33 is internally provided with an air cavity; the upper side and the lower side of the baffle 32 are provided with air bag strips 8, and the air bag strips 8 are in communication with the air cavity. Through this arrangement, on the one hand, when the sealing strip 33 is attached and extruded on the filter plate 7, the gas in the air cavity can extrude the sealing strip 33, so that it is fully attached to the filter plate 7, improving the sealing effect. On the other hand, the gas in the air cavity enters the air bag strip 8, which can achieve the sealing of the upper and lower sides of the baffle 32.

[0048] The specific implementation is as follows:

[0049] The device is installed as follows:

[0050] The motor (driving member 36) is installed in a proper position to ensure that it can drive the rotating shaft 31 to rotate, and the control circuit of the motor is connected normally to enable the opening and closing operations. The rotating shaft 31 is installed in the water tank 5 and is ensured to rotate flexibly. The baffle 32, filter plate 7, sealing strip 33, worm wheel 34 and worm 35 and other components are installed in the water tank 5 according to the design requirements. Among them, the filter plate 7 is installed on the side of the baffle 32 away from the sealing strip 33, except for the baffle 32 close to the air pipe 41. The water inlet of the water inlet pipe 51, the water outlet of the water outlet pipe 52, the air inlet of the air pipe 41 and the air outlet of the activated carbon filter device 2 are installed on the same side of the water tank 5, and the pipelines are ensured to be firmly connected without water leakage and air leakage. The air cavity is arranged in the sealing strip 33, and the air bag strip 8 is installed on the upper side and the lower side of the baffle 32 and communicates with the air cavity.

[0051] The use operation is as follows:

[0052] In normal use, the water tank 5 is first filled with water through the water inlet pipe 51. Then the motor is started, the motor drives the rotating shaft 31 to rotate, and the water is stirred. The exhaust gas enters the water tank 5 through the air inlet of the air pipe 41 and is contacted with the water to be preliminarily purified. When the gas passes through the filter plate 7, it is divided into small bubbles to further improve the purification effect. When water saving is needed, only half of the water tank 5 is used, the baffle 32 is adjusted to a parallel state, the sealing strip 33 is attached to the adjacent filter plate 7 and the inner wall of the water tank to divide the water tank into two chambers. At this time, water is injected into one of the chambers through the water inlet pipe 51 to the appropriate water level for exhaust gas purification. In this process, the worm wheel 34 and the worm 35 will automatically cooperate to form a self-locking to prevent the baffle 32 from rotating due to water pressure. At the same time, the gas in the air cavity in the sealing strip 33 will extrude the sealing strip according to the actual situation to better attach to the filter plate 7, and part of the gas enters the air bag strip 8 to realize the sealing of the upper and lower sides of the baffle 32.

[0053] The working principle of the present application is as follows:

[0054] In use, the waste generated by green printing is stored in the waste box 1, the fan 4 is started to suck the waste in the waste box 1 out, and is transported to the water tank 5 through the air pipe 41, before the waste enters the water tank 5, the gas concentration detector 6 detects the concentration, if the harmful gas concentration in the waste is high, the baffle 32 is arranged vertically to the length direction of the water tank 5, when the concentration is in the middle, the position of the baffle 32 is staggered, and when the concentration is small, the baffle 32 is arranged in parallel, so that the precision control of waste purification treatment is realized, during adjustment, the worm 35 and the worm wheel 34 are driven to rotate by rotating the driving part 36, the shaft 31 drives the baffle 32 to rotate correspondingly, adjustment is realized, and the harmful components are dissolved in water during the movement of the waste in the water tank 5, so that the waste is preliminarily purified, and then moves to the activated carbon filter device 2 at the other end of the water tank 5, is further purified, and finally the purified gas is recycled.

[0055] Further, it also includes:

[0056] Waste gas and water contact purification: the main purpose of the device is to purify waste gas, and water needs to be filled in the water tank 5 during normal use. The rotating shaft 31 is driven by the motor (driving part 36) to rotate continuously, thereby stirring the water in the water tank 5. The rotating water flow can increase the contact area of waste gas and water, for example, large air bubbles entering the water are changed into small air bubbles, so that the waste gas is more fully contacted with the water, thereby improving the purification effect. Even if the water tank is not filled with water, the upper layer of waste gas can be re-dissolved in the water during the shaking process, and the purification process continues.

[0057] Filter plate refines bubbles: in addition to the baffle 32 near the air pipe 41, the other side of the baffle 32 away from the sealing strip 33 is provided with a filter plate 7. When the waste gas passes through the filter plate 7, the filter plate 7 will divide the large bubbles into small bubbles, further increasing the contact area of waste gas and water, thereby improving the purification efficiency.

[0058] Water tank chamber separation and water saving: when the baffles 32 are arranged in a line and side by side, the sealing strip 33 can be attached to the adjacent filter plates 7, and the baffle 32 near the air pipe 41 is attached to the inner wall of the water tank 5, so that the water tank 5 is divided into two chambers. At this time, only half of the water tank 5 can be used to hold water for waste gas purification, and the other half is not filled with water, achieving the purpose of water saving, especially suitable for situations that require frequent water changes.

[0059] Self-locking ensures sealing: in the case of the water tank being divided into two chambers, self-locking is formed by the cooperation of the worm wheel 34 and the worm 35, preventing the baffle 32 from rotating under the pressure of the water, thereby ensuring the sealing of the separated chambers, avoiding the flow of water from one chamber to another, affecting the purification effect and water saving function.

[0060] The working principle of the sealing structure is that the sealing strip 33 is internally provided with an air cavity, the baffle 32 is provided with the air bag strip 8 in communication with the air cavity on the upper side and the lower side. When the sealing strip 33 is attached and extruded on the filter plate 7, the gas in the air cavity can extrude the sealing strip 33, so that the sealing strip 33 is more fully attached to the filter plate 7, and the sealing effect is improved. At the same time, the gas in the air cavity enters the air bag strip 8, the upper and lower sides of the baffle 32 are sealed, and the sealing property of the whole device is further enhanced.

[0061] In summary: the waste purification and recycling device applied to green printing packaging, by setting the adjusting mechanism 3, the flow path and speed of the waste in the water tank 5 can be flexibly adjusted according to the different harmful gas concentrations in the waste, and the purification effect and processing efficiency are improved.
