Description

Technical Field

[0001] This invention relates to the field of waste gas treatment technology, specifically to a waste gas collection and treatment device for the manufacture of plush toys. Background Technology

[0002] During the manufacturing process of plush toys, the painting process generates a large amount of acidic waste gas. This waste gas contains harmful components left over from the paint spraying process, as well as impurities such as fine plush fibers and paint mist particles. If it is directly emitted, it will pollute the air, harm human health, and does not meet environmental emission standards.

[0003] For example, utility model application number 201721382670.X discloses a toy workshop exhaust gas collection and treatment device, including a support platform and an acid-base neutralization chamber. This toy workshop exhaust gas collection and treatment device employs a microbubble device, a gas guide pipe, an observation window, a phenolphthalein bottle, and an acid-base detection port, which can increase the neutralization effect and speed of acidic exhaust gas. However, existing exhaust gas treatment devices are currently unable to remove acidic substances and fine impurities. Furthermore, impurities such as lint and fibers easily clog the filter, leading to decreased treatment efficiency, frequent downtime for maintenance, and increased operation and maintenance costs.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a waste gas collection and treatment device for plush toy manufacturing. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a waste gas collection and treatment device for plush toy manufacturing, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a waste gas collection and treatment device for plush toy manufacturing, comprising a neutralizing frame and a fan. A drive assembly for providing power is provided on one side of the neutralizing frame. The drive assembly includes a drive motor, a drive roller, a connecting shaft, and a support frame. The output end of the drive motor is fitted with the drive roller, and a connecting shaft is located in the middle of one side of the drive roller. A support frame is annularly distributed on the outer surface of the connecting shaft, and an auxiliary disc is provided on one side of the support frame. A filter screen is located in the middle of the auxiliary disc. A straight belt is provided on the outer surface of the drive roller, and two sets of transmission rollers are mounted on the top of the straight belt. One set of transmission rollers has a connecting plate in the middle of one side, and a fan is located on one side of the connecting plate. The outer surface of the other set of transmission rollers has an inclined belt, and transmission roller one is installed at the bottom of the inclined belt. The end of transmission roller one is provided with a steering component for auxiliary steering, and the steering component includes bevel gear one, bevel gear two and a shaft. The outer surface of bevel gear one is meshed with bevel gear two, and a shaft is provided in the middle of one side of bevel gear two. The end of the shaft is provided with an auxiliary component for auxiliary filter vibration, and the auxiliary component includes a half tooth, a rack and a vertical plate. The outer surface of the half tooth is meshed with the rack, and a vertical plate is slidably provided on one side of the rack.

[0007] Furthermore, the auxiliary component also includes an external spring, which is provided on the outside of the rack near the neutralizing frame.

[0008] Furthermore, a spring is arranged in a ring inside the auxiliary disc, and a fixing block is installed at one end of the spring, and one side of the outer surface of the filter screen is fixedly connected to the fixing block.

[0009] Furthermore, an inner frame is provided in the middle of the auxiliary disk, and one side of the inner frame is connected to the connecting shaft.

[0010] Furthermore, a protective component for protecting the filter screen is provided on one side of the neutralization frame, and the protective component includes an outer cover, a fixing rod and an air duct. The outer cover is located outside the auxiliary plate, and the air duct is installed inside the thread of the outer cover. A fixing rod is fixedly installed on one outer surface of the outer cover, and the end of the fixing rod is fixed to the neutralization frame by bolts.

[0011] Furthermore, a flow equalization plate is provided inside the neutralization frame, and a water mist separator is installed above the flow equalization plate.

[0012] Furthermore, a filter frame is connected to the top of the neutralizing frame via a pipe, and the filter frame is equipped with an adjustment component for quick replacement.

[0013] Furthermore, the adjustment component includes an adsorption frame, an internal frame, a hydraulic rod and a side frame, and an adsorption frame is arranged inside the side frame. The external of the adsorption frame is snap-fitted with an internal frame, and the internal frame is in a "U" shape structure. And an internal frame is installed on the outside of one side of the internal frame.

[0014] Furthermore, a duct is installed at the bottom of the filter frame, and an exhaust fan is arranged at the end of the duct, and an exhaust duct is arranged at the top of the exhaust fan.

[0015] Furthermore, a liquid collecting cylinder is communicated and arranged at the bottom of the neutralization frame, an inclined pipe is communicated and installed on one side of the liquid collecting cylinder, and a threaded cover is arranged at the bottom of the liquid collecting cylinder in a threaded manner.

[0016] The present invention provides an exhaust gas collection and treatment device for manufacturing plush toys, and has the following beneficial effects: 1. The exhaust gas collection and treatment device for manufacturing plush toys, through a single driving motor, via a precision mechanical transmission chain such as a driving roller, a belt, a gear, a cam (half-tooth), etc., synchronously and automatically drives the filter screen to perform three physical dust cleaning actions of "rotary cleaning, reverse blowing, and high-frequency vibration". This linkage design is not a simple superposition of functions, but constitutes a collaborative composite dust cleaning system: rotation makes the filter screen fully exposed and prevents fixed-point accumulation; reverse blowing removes loose attachments; high-frequency vibration strongly peels off the plush fibers and paint mist particles firmly combined due to adhesion force. Compared with the devices in the prior art with a static layout of the filter screen or a single dust cleaning method (such as only relying on reverse blowing), the present invention can actively, continuously, and efficiently prevent the filter screen from being blocked, significantly reduces the system operation resistance, avoids the attenuation of the treatment efficiency and frequent shutdown maintenance caused by the decrease in the permeability of the filter screen, and thus greatly improves the operation stability, treatment efficiency and the service life of the filter screen of the device.

[0017] 2. The exhaust gas collection and treatment device for manufacturing plush toys integrates a variety of purification units, and the process design is compact and efficient. The exhaust gas first passes through a flow equalizing plate to achieve uniform air distribution, and then fully contacts with the alkaline atomized droplets generated by the water mist separator to complete an efficient acid-base neutralization reaction, thoroughly removing acidic components such as SO2 and NOx; the waste liquid generated by the neutralization is collected by the liquid collecting cylinder and is convenient for discharge; finally, the exhaust gas enters the adsorption frame for deep purification to adsorb residual trace harmful substances. This multi-stage purification process is tailored to the physical and chemical properties of the painting exhaust gas, ensuring that the finally discharged gas can stably meet strict environmental protection standards.

[0018] 3. This waste gas collection and treatment device for plush toy manufacturing addresses the maintenance pain point of replacing saturated adsorption materials. The invention incorporates an adjustment component driven by a hydraulic rod and fitted with a built-in frame. This component accommodates two sets of adsorption frames, and their working positions can be quickly switched via the extension and retraction of the hydraulic rod. When one set of adsorption frames becomes saturated, it can be removed from the system online for replacement, while the other set immediately begins operation, ensuring continuous and uninterrupted operation of the entire waste gas treatment process. This avoids system downtime caused by traditional replacement methods, making it particularly suitable for industrial continuous production scenarios and significantly reducing production capacity losses due to maintenance. Simultaneously, the core dust removal function is entirely achieved through mechanical linkage, and the purification process is driven by conventional equipment such as fans, pumps, and valves, eliminating the need for complex multi-motor control systems or advanced programmable components. This not only improves the mechanical reliability of the system but also significantly reduces electrical control complexity and failure rate, while also reducing the frequency of daily inspections and manual dust removal.

[0021] The embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.

[0022] like Figures 1-9As shown, the present invention provides a technical solution: a waste gas collection and treatment device for plush toy manufacturing, comprising a neutralization frame 1, a filter frame 2, an air guide duct 3, an exhaust fan 4, an exhaust pipe 5, a protective component 6, an outer cover 601, a fixing rod 602, an air duct 603, a support plate 7, a liquid collection cylinder 8, a threaded cap 9, an inclined pipe 10, a water mist separator 11, a flow equalization plate 12, an auxiliary plate 13, an inner frame 14, a first transmission roller 15, an inclined belt 16, a drive component 17, a drive motor 1701, a drive roller 1702, a connecting shaft 1703, a support frame 1704, a filter screen 18, a straight belt 19, a second transmission roller 20, a connecting plate 21, a fan 22, an adjustment component 23, an adsorption frame 2301, an inner frame 2302, a hydraulic rod 2303, a side frame 2304, and a fixed... The system includes a fixed block 24, a spring 25, a steering assembly 26, a bevel gear 1 2601, a bevel gear 2602, a shaft 2603, an auxiliary assembly 27, a half-tooth 2701, a rack 2702, a vertical plate 2703, and an external spring 2704. A drive assembly 17 for providing power is provided on one side of the central frame 1. The drive assembly 17 includes a drive motor 1701, a drive roller 1702, a connecting shaft 1703, and a support frame 1704. The output end of the drive motor 1701 is equipped with the drive roller 1702, and a connecting shaft 1703 is located in the middle of one side of the drive roller 1702. The outer surface of the connecting shaft 1703 is annularly distributed with the support frame 1704, and an auxiliary disk 13 is located on one side of the support frame 1704. A filter screen 18 is located in the middle of the auxiliary disk 13. A straight belt 19 is provided on the outer surface of the moving roller 1702, and two sets of transmission rollers 20 are installed on the top of the straight belt 19. A connecting plate 21 is provided in the middle of one side of one set of transmission rollers 20, and the fan 22 is located on one side of the connecting plate 21. An inclined belt 16 is provided on the outer surface of the other set of transmission rollers 20, and a transmission roller 15 is installed at the bottom of the inclined belt 16. A steering assembly 26 for auxiliary steering is provided at the end of the transmission roller 15. The steering assembly 26 includes a bevel tooth 2601, a bevel tooth 2602, and a shaft 2603. The bevel tooth 2602 is meshed on the outer surface of the bevel tooth 2601, and the shaft 2603 is provided in the middle of one side of the bevel tooth 2602. An auxiliary device for assisting the vibration of the filter screen 18 is installed at the end of the shaft 2603. Component 27, and auxiliary component 27 includes a half-tooth 2701, a rack 2702, and a vertical plate 2703. Auxiliary component 27 also includes an external spring 2704. An external spring 2704 is provided on the side of the rack 2702 near the neutral frame 1. The rack 2702 is meshed with the outer surface of the half-tooth 2701, and the vertical plate 2703 is slidably provided on one side of the rack 2702. After the drive motor 1701 is started, its output end drives the active roller 1702 to rotate. The active roller 1702 drives the annularly distributed support frame 1704 to rotate synchronously through the connecting shaft 1703 in the middle, thereby driving the auxiliary disk 13 connected to the support frame 1704 to rotate. The filter screen 18 in the middle of the auxiliary disk 13 rotates accordingly, preparing for subsequent exhaust gas filtration and anti-clogging. At the same time...The active roller 1702 drives two sets of transmission rollers 20 to rotate synchronously via a straight belt 19 on its outer surface, achieving power distribution. One set of transmission rollers 20 drives a fan 22 to rotate via a connecting disc 21 on one side. The fan 22 generates airflow, which is directly blown onto the filter screen 18. By blowing air in reverse, it cleans the impurities attached to the surface of the filter screen 18, helping to ensure the filter screen 18 is transparent. At the same time, the other set of transmission rollers 20 drives a transmission roller 15 at the bottom to rotate via an inclined belt 16 on its outer surface. The steering component 26 at the end of the transmission roller 15 realizes the conversion of power direction, and the transmission roller 15 drives... The first bevel gear 2601 rotates, engaging with the second bevel gear 2602, converting the horizontal rotation into the vertical rotation of the shaft 2603. The shaft 2603 then drives the auxiliary component 27 at its end. Within the auxiliary component 27, the shaft 2603 drives the half-tooth 2701 to rotate. The half-tooth 2701 intermittently meshes with the rack 2702. Since the rack 2702 slides on the vertical plate 2703, and an external spring 2704 is located on the side of the rack 2702 near the neutral frame 1, the rotation of the half-tooth 2701 pushes the rack 2702 to slide back and forth, thereby causing the filter screen 18 to vibrate through transmission. Simultaneously, the annular spring 25 inside the auxiliary disk 13 engages with the fixing block 24, and one side of the outer surface of the filter screen 18 is fixedly connected to the fixing block 24, further enhancing the vibration effect of the filter screen 18, promptly shaking off impurities attached to the filter screen 18, preventing clogging, and ensuring smooth flow of exhaust gas. Furthermore, the inner frame 14 in the middle of the auxiliary disc 13 is connected to the connecting shaft 1703, further improving the stability of the rotation of the auxiliary disc 13 and the filter screen 18.

[0023] like Figure 1 , Figure 2 and Figure 4 As shown, a spring 25 is annularly arranged inside the auxiliary disk 13, and a fixing block 24 is installed at one end of the spring 25. One side of the outer surface of the filter screen 18 is fixedly connected to the fixing block 24. An inner frame 14 is provided in the middle of the auxiliary disk 13, and one side of the inner frame 14 is connected to the connecting shaft 1703. A protective component 6 for protecting the filter screen 18 is provided on one side of the neutralization frame 1. The protective component 6 includes an outer cover 601, a fixing rod 602, and an air duct 603. The outer cover 601 is provided on the auxiliary disk 13. The outer casing 601 has an internal threaded air duct 603 installed on its exterior. A fixing rod 602 is fixedly installed on one side of the outer surface of the outer casing 601, and the end of the fixing rod 602 is fixed to the neutralization frame 1 by bolts. A flow equalization plate 12 is provided inside the neutralization frame 1, and a water mist separator 11 is installed above the flow equalization plate 12. During the manufacturing of plush toys, local painting is performed, which generates exhaust gas. This exhaust gas is acidic. The water mist separator 11 is connected to a pre-mixed neutral solution through a pipeline pump.

[0024] like Figure 1, Figure 2 and Figure 6 As shown, a liquid collecting cylinder 8 is connected and arranged at the bottom of the neutralization box 1. One side of the liquid collecting cylinder 8 is connected and installed with an inclined pipe 10. And a threaded cover 9 is arranged at the bottom of the liquid collecting cylinder 8 in a threaded manner. After a period of time, by rotating the threaded cover 9, the acid-base neutralization liquid in the liquid collecting cylinder 8 is discharged. The acidic waste gas entering the neutralization box 1 first passes through the flow equalizing plate 12 inside. The flow equalizing plate 12 evenly disperses the waste gas, enabling the waste gas to fully contact the purification medium. The water mist separator 11 in the neutralization box 1 is connected to a pre-prepared neutral solution through a pipeline pump. The water mist separator 11 atomizes the neutral solution and sprays it into the evenly flowing acidic waste gas. The acidic waste gas and the neutral atomized solution undergo an acid-base neutralization reaction, effectively removing the acidic substances in the waste gas and completing the neutralization and purification of the waste gas. The waste liquid generated by the neutralization reaction will settle to the bottom of the neutralization box 1 and is collected through the connected liquid collecting cylinder 8. The inclined pipe 10 on one side of the liquid collecting cylinder 8 can assist in guiding the waste liquid and prevent the waste liquid from accumulating. After being used for a period of time, by rotating the threaded cover 9 at the bottom of the liquid collecting cylinder 8, the acid-base neutralization waste liquid in the liquid collecting cylinder 8 can be discharged, facilitating subsequent treatment and device maintenance. The top of the neutralization box 1 is connected to a filter box 2 through a pipeline. And an adjustment component 23 for quick replacement is arranged inside the filter box 2. A duct 3 is installed at the bottom of the filter box 2. And an exhaust fan 4 is arranged at the end of the duct 3. An exhaust duct 5 is arranged at the top of the exhaust fan 4. The adjustment component 23 includes an adsorption frame 2301, an internal frame 2302, a hydraulic rod 2303, and a side frame 2304. And the adsorption frame 2301 is arranged inside the side frame 2304. The external of the adsorption frame 2301 is snap-fitted with the internal frame 2302. And the internal frame 2302 is in a "C" - shaped structure. And an internal frame 2302 is installed outside one side of the internal frame 2302. The waste gas after neutralization and purification enters the filter box 2 through the pipeline at the top of the neutralization box 1. The adjustment component 23 inside the filter box 2 is responsible for further filtering and adsorbing the waste gas, removing the fine impurities and harmful components remaining in the waste gas. In the adjustment component 23, the side frame 2304 provides installation support for the adsorption frame 2301. Adsorption materials such as activated carbon can be placed inside the adsorption frame 2301 to deeply purify the waste gas. The "C" - shaped internal frame 2302 snap-fitted outside the adsorption frame 2301, in cooperation with the telescopic action of the hydraulic rod 2303, can realize the position replacement of the two adsorption frames 2301 with respect to the filter box 2, facilitating the replacement of the adsorption materials and also avoiding the interruption of waste gas treatment and ensuring the stability of the filtering and adsorption effect.

[0025] To sum up, as Figures 1-9As shown, this waste gas collection and treatment device for plush toy manufacturing operates by starting the drive motor 1701, which in turn drives the active roller 1702 to rotate at a constant speed. The active roller 1702, through the connecting shaft 1703 in the middle, drives the annularly distributed support frame 1704 to rotate synchronously, thereby driving the auxiliary disk 13 connected to the support frame 1704 to rotate. The filter screen 18 in the middle of the auxiliary disk 13 rotates synchronously, preparing for subsequent waste gas filtration and anti-clogging operations. Simultaneously, the inner frame 14 in the middle of the auxiliary disk 13 remains connected to the connecting shaft 1703, further improving the stability of the rotation of the auxiliary disk 13 and the filter screen 18. The active roller 1702, through the straight belt 19 wound around its outer surface, drives two sets of transmission rollers 20 to rotate synchronously, achieving power diversion. The fan 22 and the steering assembly 26 are driven to operate respectively. The transmission roller 15 drives the bevel gear 2601 to rotate. The bevel gear 2601 and the meshing bevel gear 2602 cooperate to convert the horizontal rotation into the vertical rotation of the shaft 2603. The shaft 2603 then drives the auxiliary assembly 27 at the end to operate. The shaft 2603 drives the half tooth 2701 to rotate. The half tooth 2701 and the rack 2702 mesh intermittently. Since the rack 2702 slides on the vertical plate 2703, and the rack 2702 is provided with an external spring 2704 on the side near the neutral frame 1, the rotation of the half tooth 2701 will push the rack 2702 to slide back and forth, thereby driving the filter screen 18 to vibrate through the transmission action. At the same time, the springs arranged in a ring inside the auxiliary disk 13 25 and the fixing block 24 cooperate to fix one side of the outer surface of the filter screen 18 to further enhance the vibration effect of the filter screen 18, shake off the impurities attached to the filter screen 18 in time, completely prevent the filter screen 18 from being blocked, and ensure smooth flow of exhaust gas. The protective component 6 on the outer side of the neutralizing frame 1 protects the filter screen 18. The outer cover 601 is installed on the outside of the auxiliary plate 13 to protect the auxiliary plate 13 and the filter screen 18. The outer cover 601 is fixed to the neutralizing frame 1 by bolts through the fixing rod 602. The air duct 603 installed in its internal thread can help guide the direction of exhaust gas flow and ensure that the exhaust gas accurately enters the filter screen 18 for preliminary filtration. The painting process in the manufacturing of plush toys will generate acidic exhaust gas. In this process, the acidic exhaust gas is introduced into the neutralizing frame 1 through the cooperation of the internal components. The process involves neutralization to remove acidic substances from the waste gas. The acidic waste gas first enters the neutralization frame 1 and passes through the internal flow equalization plate 12. The flow equalization plate 12 evenly disperses the waste gas, ensuring that the waste gas comes into full contact with the subsequent purification medium, alkaline atomized solution, thus avoiding incomplete neutralization due to excessively high local waste gas concentration. The water mist separator 11 inside the neutralization frame 1 is connected to the pre-prepared alkaline solution via a pipeline pump. After the water mist separator 11 atomizes the alkaline solution, it is evenly sprayed onto the acidic waste gas after flow equalization. The acidic waste gas and the alkaline atomized solution undergo an acid-base neutralization reaction, effectively removing acidic substances from the waste gas and completing the initial neutralization and purification of the waste gas. The waste liquid produced by the neutralization reaction will settle to the bottom of the neutralization frame 1 due to gravity and be collected centrally through the liquid collection cylinder 8 connected to the bottom of the neutralization frame 1.The inclined tube 10 connected and installed on one side of the liquid collecting cylinder 8 can assist in guiding the waste liquid, preventing the waste liquid from accumulating at the bottom of the neutralization frame 1, ensuring the continuous and stable progress of the neutralization reaction. After a period of use, by rotating the threaded cover 9 at the bottom of the liquid collecting cylinder 8, the acid-base neutralized waste liquid collected in the liquid collecting cylinder 8 can be discharged, facilitating subsequent waste liquid treatment and device maintenance, and avoiding the influence of waste liquid accumulation on the operation of the device. The neutralized and purified waste gas enters the filter frame 2 through the pipeline at the top of the neutralization frame 1. The adjustment component 23 inside the filter frame 2 is responsible for further purifying the waste gas. The side frame 2304 provides stable installation support for the adsorption frame 2301. A cover sealed with bolts is provided at the top of the side frame 2304, which is a detachable design. Adsorption materials such as activated carbon can be placed inside the adsorption frame 2301. When the waste gas passes through the adsorption frame 2301, the adsorption materials will adsorb the residual fine impurities and harmful components in the waste gas, achieving the deep purification of the waste gas. To avoid the influence of the saturation of the adsorption materials on the purification effect and prevent the interruption of waste gas treatment, the adjustment component 23 is designed with a convenient adsorption frame replacement structure. An inverted "U" - shaped built - in frame 2302 is snap - fitted and installed outside the adsorption frame 2301. A hydraulic rod 2303 is installed outside one side of the built - in frame 2302. Through the telescopic action of the hydraulic rod 2303, the rapid replacement of the positions of the two adsorption frames 2301 with respect to the filter frame 2 can be achieved, facilitating the timely replacement of the saturated adsorption materials, ensuring the stability of the filtration and adsorption effect, and at the same time not affecting the continuous progress of waste gas treatment. A duct 3 is installed at the bottom of the filter frame 2. An exhaust fan 4 is provided at the end of the duct 3. After starting the exhaust fan 4, negative pressure suction will be generated, sucking the purified waste gas in the filter frame 2 into the exhaust fan 4 through the duct 3, and then discharging the purified waste gas through the exhaust duct 5 at the top of the exhaust fan 4, completing the entire waste gas collection and treatment process.;
