[0014] Compared with the prior art, the present invention has the following beneficial effects: 1.

In this invention, the adsorption mechanism uses selective adsorption with activated carbon, and the selective opening and closing of the activated carbon is achieved by rotation, realizing the rotation operation of the activated carbon. When a certain activated carbon is saturated, it can be replaced by switching off the activated carbon cylinder, while other activated carbons continue to work normally. This avoids the problem of needing to shut down the traditional whole-body replacement adsorption mechanism and ensures the continuity of waste gas treatment in the production line. Furthermore, the activated carbons are controlled independently in pairs, allowing for targeted replacement of saturated activated carbon, avoiding waste of unsaturated activated carbon and reducing consumable costs.

[0015] 3. The stable leak detection mechanism in this invention treats gas leaks by combining three aspects: reducing pipeline vibration, sealing for detection, and timely extraction. This not only prevents gas from leaking into the external environment and reducing the risk of personnel exposure, but also extends the connection life between the pipeline and the secondary cleaning mechanism, and can promptly detect leak points between the pipeline and the secondary cleaning mechanism.

[0019] Furthermore, in this invention, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the invention. They are merely used to distinguish components or operations described using the same technical terms and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions and features of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0020] The present invention provides the following embodiments: Example 1

[0021] This invention provides a waste gas treatment device for a wine bottle spray painting production line, such as... Figure 1 and Figure 10 As shown, it includes a support platform 1, a collection mechanism 2 on the support platform 1, a secondary cleaning mechanism 5 on the side of the support platform 1, a pipe 11 between the collection mechanism 2 and the secondary cleaning mechanism 5, an adsorption mechanism 6 inside the support platform 1, and a stable leak detection mechanism 9 above the secondary cleaning mechanism 5. The collection mechanism 2, located on the support platform 1, collects the waste gas generated during the bottle painting process using negative pressure suction and airflow guidance. It also uses water flow to initially adsorb and remove larger impurities such as paint mist particles from the waste gas. The secondary removal mechanism 5, located on the side of the support platform 1, further treats the collected waste gas, removing larger impurities such as paint mist particles. It works by colliding with the waste gas, causing larger impurities like paint mist particles to adhere to the secondary removal mechanism 5, and then condensing and removing water vapor from the waste gas through cooling. The adsorption mechanism 6, located within the support platform 1, is mainly used to adsorb volatile organic compounds (VOCs) and other harmful substances from the waste gas. It uses activated carbon as the adsorption medium. After dispersing the waste gas, the adsorption mechanism 6 selectively passes it into the activated carbon adsorption material for exhaust, achieving a rotating adsorption process using the activated carbon adsorption material.

[0022] The stable leak detection mechanism 9 includes an annular sleeve 91, which is fitted on the outside of the pipe 11. The annular sleeve 91 is bolted to the side of the support platform 1. A side drain pipe 92 is connected through and fixed to the side of the annular sleeve 91. The output end of the side drain pipe 92 is connected to the input end of the one-way sealed air pump 93. The one-way sealed air pump 93 is bolted to the side of the support platform 1. The output end of the one-way sealed air pump 93 is connected to the collection mechanism 2. A stabilizing structure 94 is provided at the top of the annular sleeve 91. A surrounding structure 10 is provided inside the annular sleeve 91.

[0023] An annular sleeve 91 is fitted onto the connection between the pipe 11 and the secondary cleaning mechanism 5. Due to heat exchange within the secondary cleaning mechanism 5 and vibrations generated by the suction from the pipe 11, there is a risk of leakage at this connection. A stabilizing structure 94 is used to adapt the annular sleeve 91 to the pipe 11 and the secondary cleaning mechanism 5, reducing the relative vibration between them. Simultaneously, a surrounding structure 10 is used to detect leaks at this connection; in the event of a leak, the leakage is discharged into the collection mechanism 2 via a unidirectional closed-loop suction pump 93 and a side drain pipe 92.

[0024] In the above technical solution, the collection mechanism 2 accurately captures the waste gas generated by the production line through negative pressure suction and airflow guidance (preventing the waste gas from spreading to the workshop). At the same time, it uses water flow to directly adsorb paint mist particles, initially removing larger paint mist particles and reducing the risk of blockage in subsequent processes. The secondary removal mechanism 5 further intercepts residual tiny paint mist particles through a combination of collision adhesion and cooling condensation. After the particles collide with the internal components of the mechanism, they lose kinetic energy and adhere. Simultaneously, the cooling process causes water vapor in the waste gas to condense, which can carry away some fine particles and cause them to settle, preventing paint mist from clogging the subsequent activated carbon adsorption material and reducing adsorption efficiency.

[0025] The adsorption mechanism 6 employs selective adsorption with activated carbon, and its rotation allows for selective opening and closing of the activated carbon, enabling continuous operation. When a particular activated carbon becomes saturated, its corresponding cylinder 73 can be switched off for replacement, while other activated carbons continue to operate normally. This avoids the downtime issue required by traditional whole-system replacement adsorption mechanisms 6, ensuring the continuity of waste gas treatment in the production line. Furthermore, the activated carbons are controlled independently in pairs, allowing for targeted replacement of saturated activated carbons, preventing waste of unsaturated activated carbon and reducing consumable costs.

[0026] The stable leak detection mechanism 9 treats gas leaks by combining three methods: reducing the vibration of the pipeline 11, sealing for detection, and timely extraction. This not only prevents gas from leaking into the external environment, but also extends the connection life between the pipeline 11 and the secondary cleaning mechanism 5, and can also detect leaks between the pipeline 11 and the secondary cleaning mechanism 5 in a timely manner.

[0027] Example 2

[0028] Based on Example 1, such as Figure 2 , Figure 3 , Figure 4 As shown, the collection mechanism 2 includes a collection back plate 21, which is bolted to the support platform 1. A blocking plate 22 is fixedly connected to the top of the collection back plate 21. An opening groove 23 is provided between the blocking plate 22 and the collection back plate 21. A spray pipe 24 is provided above the opening groove 23. The spray pipe 24 is bolted to the side wall of the collection back plate 21. An exhaust port 25 is provided at the top of the collection back plate 21. A circulation structure 3 is provided at the bottom of the collection back plate 21.

[0029] Paint mist-containing exhaust gas generated during the bottle painting process enters the opening slot 23 between the collection back plate 21 and the interception plate 22 under the guidance of airflow. At this time, the spray pipe 24 (fixed to the side wall of the collection back plate 21) supplies water through the water pump 35, continuously spraying water onto the collection back plate 21 to form a water curtain. When the exhaust gas passes through the water curtain, the liquid paint mist particles collide with the water curtain and are adsorbed and intercepted by the water (the paint mist condenses into paint sludge after contact with the water and sinks with the water flow) and is discharged from the exhaust port 25 at the top of the collection back plate 21.

[0030] The circulation structure 3 includes a circulation water tank 31, which is located at the bottom of the collection back plate 21. The bottom of the collection back plate 21 is provided with a pull-out groove 32. The circulation water tank 31 is slidably connected in the pull-out groove 32. A shielding folding plate 33 is fixedly connected to the collection back plate 21. A sliding sleeve 34 is fixedly connected to the top of the shielding folding plate 33. A water pump 35 is slidably connected in the sliding sleeve 34. The output end of the water pump 35 is connected to the shower pipe 24 through a telescopic hose 36. The input end of the water pump 35 is connected to the circulation water tank 31 and the water supply pipe. A lifting structure 4 is provided on the side of the shielding folding plate 33.

[0031] After spraying, the wastewater carrying paint residue falls into the circulating water tank 31 at the bottom of the collection back plate 21 (the circulating water tank 31 is slidably connected in the pull-out groove 32, and can be pulled out when cleaning is required). The paint residue floats on the surface of the water in the circulating water tank 31. The water pump 35 draws circulating water from the circulating water tank 31 through the input end, and supplements it with new water through the water supply pipe. Then, the water is transported to the spray pipe 24 through the telescopic hose 36, forming a closed loop of spraying-collection-circulation, reducing water consumption.

[0032] When the circulating water tank 31 is pulled out, the lifting structure 4 drives the water pump 35 to move up and down. The lifting structure 4 includes a lifting rod 41, which passes through and is slidably connected to the baffle plate 33. A compression elastic element 42 is provided between the lifting rod 41 and the baffle plate 33. The top end of the lifting rod 41 is connected to the water pump 35. A rotating rod 43 is provided on one side of the circulating water tank 31. The middle part of the rotating rod 43 is rotatably connected to the baffle plate 33. A sliding groove 44 is provided on the rotating rod 43. The bottom end of the lifting rod 41 is slidably connected in the sliding groove 44.

[0033] When the water level in the circulating water tank 31 changes (e.g., paint residue buildup causing a drop in water level) or when the circulating water tank 31 needs to be pulled out for cleaning, the circulating water tank 31 is pulled out of the pull-out groove 32 until the side of the circulating water tank 31 is no longer in contact with one end of the rotating rod 43. The lifting rod 41 slides upward under the action of the compression elastic element 42, and drives the water pump 35 to slide along the sliding sleeve 34 to disengage it from the circulating water tank 31; during the upward movement of the lifting rod 41, its bottom end slides along the sliding groove 44, pulling the other end of the rotating rod 43 to rotate around the connection point with the baffle plate 33, and the circulating water tank 31 can then be pulled out.

[0034] When the circulating water tank 31 is inserted into the pull-out groove 32, the side of the circulating water tank 31 contacts one end of the rotating rod 43, pushing the rotating rod 43 to rotate around the connection point with the shielding folding plate 33. The other end of the rotating rod 43 pulls the lifting rod 41 down and makes it slide along the sliding groove 44, driving the water pump 35 to slide along the sliding sleeve 34 until it is inserted into the circulating water tank 31.

[0035] In the above technical solution, the collecting backplate 21 and the blocking plate 22 work together with the spray pipe 24 to capture paint mist particles, preventing paint mist from entering the subsequent adsorption mechanism 6 and clogging the adsorption material (such as activated carbon), thus extending the service life of the core purification components. The closed-loop system composed of the circulating water tank 31 and the water pump 35 can reuse the spray water (only requiring the replenishment of a small amount of evaporated or lost water), reducing wastewater discharge. The circulating water tank 31 adopts a pull-out design, which can be quickly removed to clean paint residue. The lifting structure 4 can be linked with the circulating water tank 31 to avoid interference between the circulating water tank 31 and the water pump 35 during the pulling process.

[0036] Example 3

[0037] Based on Example 2, such as Figure 5 As shown, the secondary cleaning mechanism 5 includes a temporary gas storage tank 51, which is bolted to the support platform 1. The input end of the temporary gas storage tank 51 is connected to the exhaust port 25 through the pipe 11. The side of the temporary gas storage tank 51 is provided with an exhaust port 52. The bottom of the temporary gas storage tank 51 is threadedly connected to a bottom sleeve 53. A supporting hollow rod 54 is fixedly connected to the center of the bottom sleeve 53. Several flow-blocking baffles 55 are fixedly connected to the supporting hollow rod 54. The flow-blocking baffles 55 are arranged alternately on the left and right sides. A semiconductor cooling chip 56 is fixedly connected to the bottom of each flow-blocking baffle 55. A drainage pipe 57 is provided on the bottom sleeve 53.

[0038] The exhaust gas (containing a small amount of fine paint mist, VOCs, and water vapor that were not captured by the water curtain) after preliminary treatment by the collection mechanism 2 enters the temporary gas storage tank 51 through the exhaust port 25 via the pipe 11. The exhaust gas diffuses within the temporary gas storage tank 51, reducing its flow velocity and providing sufficient reaction time for subsequent treatment. Several staggered baffles 55 are installed on the supporting hollow rod 54 (fixed to the center of the base sleeve 53) inside the temporary gas storage tank 51, forming a tortuous channel. As the exhaust gas passes through the channel, it must circulate multiple times. Larger residual paint mist particles collide with the surface of the baffles 55 due to inertia and are intercepted and captured. Furthermore, the airflow velocity is disturbed by the change in the channel cross-section, increasing the contact probability between fine particles and the baffles 55, thus improving the interception efficiency.

[0039] Water vapor and some high-boiling-point VOCs (such as high-boiling-point esters and alcohols) in the exhaust gas condense into liquid upon cooling, adhering to the surface of the baffle 55 and gradually converging into droplets, which then slide down the baffle 55 to the bottom sleeve 53. The condensed mixed liquid (containing dissolved VOCs and trace amounts of paint mist) is discharged through the drain pipe 57 on the bottom sleeve 53 (which can be connected to a wastewater treatment system). After secondary treatment, most of the water vapor, residual paint mist, and high-boiling-point VOCs in the exhaust gas are removed, and the gas is finally discharged from the exhaust port 52 on the side of the temporary gas storage tank 51, entering the subsequent adsorption mechanism 6 for deep purification. When it is necessary to clean the secondary cleaning mechanism 5, the bottom sleeve 53 can be removed from the bottom of the temporary gas storage tank 51 for easy cleaning.

[0040] In the above technical solution, the multi-stage interception of the flow-blocking baffle 55 can further remove residual paint mist (especially fine particles not captured by the collection mechanism 2). The condensation effect of the semiconductor cooling chip 56 can separate water vapor and high-boiling-point VOCs in the exhaust gas, significantly reducing the processing pressure of the subsequent adsorption mechanism 6 and improving the overall purification efficiency. The bottom sleeve 53 is threadedly connected to the temporary gas storage tank 51, which can be quickly disassembled and cleaned of the paint residue deposited on the surface of the flow-blocking baffle 55. The temporary gas storage tank 51 can balance the flow fluctuation of the exhaust gas discharged from the collection mechanism 2, ensuring a stable flow of exhaust gas entering the subsequent adsorption mechanism 6 and avoiding fluctuations in purification efficiency caused by impact load.

[0041] Example 4

[0042] Based on Example 3, such as Figure 6 , Figure 7 , Figure 8 , Figure 9As shown, the adsorption mechanism 6 includes an adsorption cylinder 61, which is bolted to the support platform 1. A centrifugal fan 62 is provided on one side of the adsorption cylinder 61 and is bolted to the support platform 1. The input end of the centrifugal fan 62 is connected to the exhaust port 52, and the output end of the centrifugal fan 62 is connected to the adsorption cylinder 61. A rotating wheel 63 is rotatably connected inside the adsorption cylinder 61. The rotating wheel 63 is provided with several airflow holes 64. A drive motor 65 is connected to the rotating wheel 63, and the output end of the drive motor 65 is connected to the rotating wheel 63. The drive motor 65 is bolted to the adsorption cylinder 61. A distribution structure 7 is provided on one side of the rotating wheel 63.

[0043] After being treated by the secondary purification mechanism 5, the exhaust gas is drawn into the exhaust port 52 by the negative pressure generated by the centrifugal fan 62. The output end of the centrifugal fan 62 pressurizes the exhaust gas and sends it into the adsorption cylinder 61, providing power and a directional flow path for exhaust gas purification. The rotor 63 inside the adsorption cylinder 61 rotates at a constant speed under the drive of the drive motor 65. Several airflow holes 64 on the rotor 63 rotate with the rotor 63, dispersing the concentrated airflow into multiple uniform airflows and guiding them to the distribution structure 7.

[0044] The distribution structure 7 includes a distribution disk 71, which is fixedly connected inside the adsorption cylinder 61. Several connecting cylinders 72 are connected through and fixedly connected to the distribution disk 71. The connecting cylinders 72 are arranged in a ring. Activated carbon cylinders 73 are threadedly connected to each of the connecting cylinders 72. Ring clamps 74 are fixedly connected inside each of the connecting cylinders 72. A switch rod 75 is slidably connected inside the ring clamp 74. A sealing plate 76 is fixedly connected to the end of the switch rod 75. A compression elastic element 77 is provided between the switch rod 75 and the ring clamp 74. A switch structure 8 is provided at the center of the distribution disk 71.

[0045] After the exhaust gas reaches the distribution structure 7, it enters the activated carbon cylinder 73 through the connecting cylinder 72 on the distribution plate 71. The VOCs (such as benzene compounds, esters, etc.) in the exhaust gas are adsorbed and trapped by the microporous structure of the activated carbon. The purified gas is discharged through the other end of the activated carbon cylinder 73. The ring clamp 74, switch rod 75, sealing plate 76 and compression elastic element 2 77 in the connecting cylinder 72 form a one-way sealing structure: under normal conditions, the compression elastic element 2 77 pushes the sealing plate 76 to fit against the port of the connecting cylinder 72, blocking the airflow; when the switch structure 8 is activated, the sealing plate 76 is opened, and the exhaust gas can enter the activated carbon cylinder 73.

[0046] The alternating operation of the activated carbon cylinder 73 is achieved through a switch structure 8. The switch structure 8 includes a switch shaft 81, which is rotatably connected to the distribution plate 71. A rotating motor 82 is bolted to the center of the distribution plate 71. The output end of the rotating motor 82 is connected to the switch shaft 81. A balance bar 83 is fixedly connected to one end of the switch shaft 81. Arc-shaped clamps 84 are fixedly connected to both ends of the balance bar 83. The arc-shaped clamps 84 are sleeved on the connecting cylinder 72. A semi-circular block 85 is fixedly connected to the arc-shaped clamps 84. The semi-circular block 85 is slidably connected to the sealing plate 76.

[0047] When the switch structure 8 is working, the rotating motor 82 drives the switch shaft 81 to rotate, which in turn drives the balance bar 83 and the arc-shaped clamps 84 at both ends to rotate synchronously (the arc-shaped clamps 84 are sleeved on the outside of the connecting cylinder 72). The semi-circular block 85 on the arc-shaped clamp 84 rotates with the arc-shaped clamp 84. When the semi-circular block 85 contacts the sealing plate 76, due to the arc-shaped structure of the semi-circular block 85, the sealing plate 76 slides relative to the semi-circular block 85. During the sliding process, the position of the sealing plate 76 is displaced according to the contour of the semi-circular block 85, causing the sealing plate 76 to disengage from the port of the connecting cylinder 72. This causes the sealing plate 76 to pull the switch rod 75 to slide along the ring clamp 74 and compress the elastic element 77, corresponding to the activated carbon cylinder 73 being in the working state. The rotating motor 82 stops working, causing the balance bar 83 to come to rest. When the activated carbon cylinder 73 is about to fail, the rotating motor 82 works again, causing the sealing plate 76 to slide relative to the outline of the semi-circular block 85 until it disengages. During this process, the sealing plate 76 gradually resets under the action of the compression elastic element 77, and the sealing plate 76 contacts the connecting cylinder 72 again, and the corresponding activated carbon cylinder 73 stops working (it can be replaced or regenerated).

[0048] In the above technical solution, the uniform gas distribution design of the activated carbon cylinder 73 and the rotor 63 ensures full contact between the waste gas and the activated carbon, avoiding the problem of unadsorbed and escaped due to excessive local airflow, and ensuring that the VOCs concentration in the treated waste gas meets the emission standards. The switch structure 8 can independently control the start and stop of any activated carbon cylinder 73. When a certain activated carbon cylinder 73 is saturated, it can be switched off for replacement, allowing other activated carbon cylinders 73 to continue working normally. This avoids the need to shut down traditional whole-system replacement adsorption devices, ensuring the continuity of waste gas treatment in the production line. The activated carbon cylinder 73 and the connecting cylinder 72 are connected by threads, allowing for quick disassembly and replacement. Furthermore, the activated carbon cylinders 73 are controlled independently in pairs, allowing for targeted replacement of saturated activated carbon, avoiding waste of unsaturated activated carbon and reducing consumable costs.

[0049] Example 5

[0050] Based on Example 3, such as Figure 10 , Figure 11As shown, the stabilizing structure 94 includes several elastic telescopic damping rods 941, which are arranged in a ring on the annular sleeve 91. Each working end of the elastic telescopic damping rod 941 is fixedly connected to an arc plate 942, which abuts against the pipe 11. An expansion joint 943 is slidably connected to the bottom of the annular sleeve 91. A compression elastic element 944 is provided between the expansion joint 943 and the annular sleeve 91. A flexible cover 945 is provided at the bottom of the expansion joint 943, which abuts against the temporary gas storage tank 51.

[0051] When the pipe 11 vibrates, the elastic telescopic damping rod 941 at the top of the annular sleeve 91 pushes the arc plate 942 to abut tightly against the outer wall of the pipe 11, offsetting the energy of the vibration of the pipe 11 and keeping the center of the pipe 11 relatively stable within a certain range. Under the elastic force of the compression elastic element 944, the bottom expansion joint 943 drives the flexible sealing ring 945 to fit against the temporary air storage tank 51, ensuring the sealing between the bottom of the annular sleeve 91 and the temporary air storage tank 51.

[0052] The surrounding structure 10 includes a surrounding toothed ring 101, which is rotatably connected to an annular sleeve 91. A drive nest 102 is provided on one side of the annular sleeve 91, and a surrounding motor 103 is provided inside the drive nest 102. The surrounding motor 103 is bolted to the annular sleeve 91, and a drive gear 104 is fixedly connected to the output end of the surrounding motor 103. The drive gear 104 meshes with the surrounding toothed ring 101, and a detection probe 105 is fixedly connected to the surrounding toothed ring 101.

[0053] The output of the circumferential motor 103 inside the drive nest 102 drives the drive gear 104 to rotate. Because the drive gear 104 meshes with the circumferential gear ring 101, the circumferential gear ring 101 rotates with the gear and makes a circular motion on the annular sleeve 91. The detection probe 105 fixed on the circumferential gear ring 101 moves with the circumferential gear ring 101 and performs 360° detection of gas concentration at different angles and positions without dead angles, and captures the leak point in real time (if the leak point is located in a specific direction, the probe will detect the concentration peak when it passes through the area), so as to achieve accurate positioning of the leak location and concentration.

[0054] In the above technical solution, the toothed ring 101 drives the detection probe 105 to move in a circular motion, and through the semi-closed structure of the annular sleeve 91 (the leaked gas is concentrated in the cavity and the concentration is not easily diluted), the detection rate of trace leaks is greatly improved.

[0055] The top elastic telescopic damping rod 941 can automatically adjust the telescopic amount according to the slight deviation of the outer diameter of the pipe 11, so that the arc plate 942 is always in close contact with the pipe 11, and can also dissipate the vibration energy of the pipe 11; the bottom expansion joint 943 and the compression elastic element 944 work together to adapt to the connection parts of different heights such as the temporary gas storage tank 51 and the pipe 11 support, with high compatibility.

[0056] Obviously, those skilled in the art can make various modifications and variations to this invention without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this invention and their equivalents, this invention also intends to include these modifications and variations.
