Abstract
Description
Technical Field
[0001] This utility model belongs to the field of furniture board drying technology, and in particular relates to a waste gas treatment device for furniture board drying. Background Technology
[0002] In the furniture manufacturing industry, drying the boards is a crucial process. During drying, the moisture in the boards evaporates, forming a large amount of water vapor. At the same time, some organic matter inside the boards also volatilizes at high temperatures, producing waste gas containing harmful substances such as volatile organic compounds, formaldehyde, and dust. If this waste gas is directly discharged into the atmosphere without effective treatment, it will not only pollute the environment but may also endanger the health of operators. Therefore, it must be purified through waste gas treatment equipment.
[0003] Currently, the treatment of exhaust gas from furniture board drying mainly adopts spray purification, which involves contacting the exhaust gas with a treatment liquid to achieve dust adsorption, cooling, and dissolution of some harmful components. However, most existing treatment devices have unreasonable spray structure designs, often using fixed spray heads with fixed spray angles and limited coverage. This causes the exhaust gas to easily form eddies or dead zones within the treatment chamber, resulting in insufficient contact with the treatment liquid. Some exhaust gas is discharged directly without effective treatment, leading to low dust removal rates and poor cooling effects. If the treatment liquid is unevenly distributed, the treatment liquid sprayed from the fixed spray heads tends to be in a localized agglomeration state, failing to disperse evenly within the treatment chamber. This not only wastes the treatment liquid but also results in insufficient contact between some high-concentration exhaust gas and the treatment liquid, thus affecting the overall purification efficiency.
[0004] To address these issues, we provide a waste gas treatment device for drying furniture boards. Utility Model Content
[0005] The purpose of this utility model is to provide a waste gas treatment device for drying furniture boards. Through the action of the diversion plate, the diversion plate in this device can rotate and fully spray water mist. When the diversion plate rotates with the feed pipe, several nozzles at its bottom rotate accordingly, so that the treatment liquid forms a multi-angle and large-area spray coverage, which can more evenly and fully contact the waste gas in the treatment shell, avoid the situation that the waste gas is not covered by the treatment liquid, enhance the cooling and dust removal effect of the waste gas, and solve the problem that most existing treatment devices have unreasonable spray structure design, mostly use fixed spray heads, fixed spray angle and limited coverage, which makes it easy for the waste gas to form eddies or dead corners in the treatment shell.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model is a waste gas treatment device for drying furniture boards, including a treatment shell, and a first bearing is fixed on the top of the treatment shell;
[0007] The inner ring of the first bearing is fixed with a feed pipe, and a support plate is fixed to the outside of the feed pipe;
[0008] A support is fixed to the bottom of the support plate;

[0016] The present invention is further configured such that the second connecting pipe and the feed pipe are rotatably connected;
[0017] A second bearing is fixed to the top of the processing shell, and a connecting rod is fixed to the inner ring of the second bearing.
[0018] The connecting rod is fixedly connected to the rotating rod.
[0019] The present invention is further configured such that: a support frame is fixed on the top of the processing shell, and the second connecting pipe passes through the support frame.
[0020] The present invention is further configured such that: the support includes a support rod, and the support rod is fixedly connected to the support plate.
[0021] The present invention is further configured such that: a protective shell is fixed to the end of the support rod away from the support plate, and a protective ball is rolled inside the protective shell;
[0022] The protective ball is rolled to the top of the processing shell.
[0023] The present invention is further configured such that: an air inlet pipe is fixed on one side of the processing shell, and a protective shell is fixed on the outside of the air inlet pipe;
[0024] The protective shell has a hollow spherical structure;

[0029] This utility model has the following beneficial effects:
[0030] 1. This utility model utilizes the function of a diverter plate. The diverter plate in this device can rotate and fully spray water mist, which is beneficial. When the diverter plate rotates with the feed pipe, several nozzles at its bottom rotate accordingly, causing the treatment liquid to form a multi-angle, large-area spray coverage. This allows for more uniform and sufficient contact with the waste gas inside the treatment chamber, avoiding situations where some waste gas is not covered by the treatment liquid. This enhances the cooling and dust removal effects on the waste gas. The rotating diverter plate drives the nozzles to form a dynamic spray, and the treatment liquid mixes with the waste gas in a more dispersed state, which can more efficiently adsorb dust and other impurities in the waste gas. The uniform spray achieved through rotation can avoid waste caused by local accumulation of treatment liquid, making the distribution of treatment liquid in the treatment chamber more reasonable. This reduces the consumption of treatment liquid while ensuring the purification effect.
[0031] 2. This utility model utilizes the processing box, which employs multi-layer filter plates to perform deep treatment on the initially treated waste gas, effectively removing residual odors and moisture. This solves the problem of waste gas still having odors and high humidity after single spray treatment, resulting in cleaner exhaust gas. Furthermore, the filter plates are fixed to the mounting plate on the top of the processing box with bolts, making disassembly and installation simple. Cleaning or replacement can be completed without complicated tools, reducing the difficulty and cost of equipment maintenance and making it suitable for long-term, high-frequency use scenarios.

Specific Implementation Example 1
[0045] Please see Figure 1-6This utility model is a waste gas treatment device for drying furniture boards, including a treatment shell 1. A first bearing 2 is fixed to the top of the treatment shell 1. A feed pipe 3 is fixed to the inner ring of the first bearing 2, and a support plate 4 is fixed to the outer side of the feed pipe 3. A support 5 is fixed to the bottom of the support plate 4. A diversion plate 6 is fixed to the bottom of the feed pipe 3, and several nozzles 7 are fixed to the bottom of the diversion plate 6. A first limiting plate 8 is fixed to the top of the feed pipe 3, and several first transmission blocks 9 are fixed to the outer side of the feed pipe 3. A motor 10 is fixed to the top of the treatment shell 1. A rotating rod 11 is fixed to the output shaft of the motor 10, and several second transmission blocks 12 are fixed to the outer side of the rotating rod 11. A transmission belt 13 is sleeved between the first transmission blocks 9 and the second transmission blocks 12. A water storage tank 14 is fixed to one side of the treatment shell 1. A water pump 15 is connected to the water storage tank 14 through a first connecting pipe. A second connecting pipe 16 is fixed to the output end of the water pump 15. A second limiting plate 17 is fixed to one end of the second connecting pipe 16. A drain pipe is fixed to the bottom of the treatment shell 1.
[0046] Specifically, the second connecting pipe 16 is rotatably connected to the feed pipe 3; a second bearing 18 is fixed to the top of the processing shell 1, and a connecting rod 19 is fixed to the inner ring of the second bearing 18; the connecting rod 19 is fixedly connected to the rotating rod 11.
[0047] Furthermore, a support frame 20 is fixed to the top of the processing shell 1, and a second connecting pipe 16 passes through the support frame 20; the support 5 includes a support rod 21, which is fixedly connected to the support plate 4; a protective shell 22 is fixed to the end of the support rod 21 away from the support plate 4, and a protective ball 23 is rolled inside the protective shell 22; the protective ball 23 is rolledly connected to the top of the processing shell 1.
[0048] The operation process of this embodiment is as follows: When using this device, the exhaust gas pipe generated by the drying of furniture boards is connected to the air inlet pipe 24 on one side of the treatment shell 1. The hollow spherical protective shell 25 outside the air inlet pipe 24 can prevent the waste liquid in the treatment shell 1 from flowing back through the air inlet pipe 24. Then, the water pump 15 is turned on, and the treatment liquid in the water storage tank 14 enters the water pump 15 through the first connecting pipe, and is then transported to the feed pipe 3 through the second connecting pipe 16. The second connecting pipe 16 passes through the support frame 20, and the support frame 20 plays a fixing role. At the same time, the second connecting pipe 16 is rotatably connected to the feed pipe 3 to ensure that the treatment liquid is transported when the feed pipe 3 rotates. Stable conveying is achieved when motor 10 is turned on. The output shaft of motor 10 drives rotating rod 11 to rotate. Rotating rod 11 is fixed to the inner ring of second bearing 18 via connecting rod 19 to ensure stable rotation. The second transmission block 12 on the outside of rotating rod 11 drives the first transmission block 9 on the outside of feed pipe 3 to rotate via transmission belt 13, causing feed pipe 3 to rotate within the inner ring of first bearing 2. The diverter plate 6 at the bottom of feed pipe 3 rotates synchronously with it. Several nozzles 7 at the bottom of diverter plate 6 evenly spray the treatment liquid into the interior of treatment shell 1. The support plate 4 on the outside of feed pipe 3 contacts the top of treatment shell 1 via support 5. The protective ball 23 rolls to reduce friction. The feed pipe 3 rotates stably; the exhaust gas enters the treatment chamber 1 through the inlet pipe 24 and comes into full contact with the treatment liquid sprayed from the rotating nozzle 7. The dust in the exhaust gas is adsorbed by the treatment liquid, and the temperature is reduced at the same time; the treated waste liquid falls to the bottom of the treatment chamber 1, is guided by the guide plate 26 at the bottom of the inner wall, and is discharged from the drain pipe. The pre-treated exhaust gas enters the processing box 27 through the outlet pipe, and passes through several filter plates 30 in sequence. The filter plates 30 adsorb the residual odor and water vapor in the exhaust gas, and the finally purified exhaust gas is discharged from the processing box 27; the diversion plate 6 in this device can rotate and fully spray water mist, which has the beneficial effect of this device. When the diversion plate 6 rotates with the feed pipe 3... When in motion, the nozzles 7 at the bottom rotate accordingly, causing the treatment liquid to form a multi-angle, wide-range spray coverage, which can more evenly and fully contact the exhaust gas in the treatment shell 1, avoiding the situation where the exhaust gas is not covered by the treatment liquid in some areas, and enhancing the cooling and dust removal effect on the exhaust gas. The rotating diverter plate 6 drives the nozzles 7 to form a dynamic spray, and the treatment liquid mixes with the exhaust gas in a more dispersed state, which can more efficiently adsorb dust and other impurities in the exhaust gas. The uniform spray achieved by rotation can avoid the waste caused by the local accumulation of treatment liquid, making the distribution of treatment liquid in the treatment shell 1 more reasonable, and reducing the consumption of treatment liquid while ensuring the purification effect. Specific Implementation Example 2
[0050] Please see Figure 1-6 Based on the first specific embodiment, an air inlet pipe 24 is fixed on one side of the processing shell 1, and a protective shell 25 is fixed on the outside of the air inlet pipe 24; the protective shell 25 is a hollow sphere structure; a guide plate 26 is fixed on the bottom of the inner wall of the processing shell 1, and a processing box 27 is fixed on the side of the processing shell 1 away from the air inlet pipe 24 through the air outlet pipe.
[0051] Specifically, the top of the processing box 27 has several placement slots 28; the bottom of the placement slots 28 is fixed with several fixing plates 29, and a filter plate 30 is slidably connected inside the placement slots 28; the top of the filter plate 30 is fixed with an mounting plate 31, the filter plate 30 can be an activated carbon plate, and the mounting plate 31 is fixedly connected to the top of the processing box 27 by bolts.
[0052] The operation process of this embodiment is as follows: After initial cooling and dust removal by the treatment shell 1, the exhaust gas enters the processing chamber 27 through the exhaust pipe. Inside the processing chamber 27, the exhaust gas passes through several layers of filter plates 30 for further treatment. The filter plates 30 can be activated carbon plates, embedded in the placement slot 28 at the top of the processing chamber 27, and supported at the bottom by a fixing plate 29 to ensure stability and full contact with the exhaust gas. The filter plates 30 utilize their own adsorption properties to capture residual odor molecules and moisture in the exhaust gas, further purifying it. After being treated by multiple layers of filter plates 30, the odor and moisture are significantly removed, and the exhaust gas is finally discharged from the outlet of the processing chamber 27, completing the entire exhaust gas purification process. When the filter plate 30 is saturated, it can be removed from the placement slot 28 by unscrewing the bolts connecting the mounting plate 31 to the top of the processing box 27, and then cleaned or replaced before reinstallation to ensure continuous purification effect. The processing box 27 in this device uses multiple layers of filter plates 30 to perform deep treatment on the pre-treated exhaust gas, effectively removing residual odors and moisture, solving the problem that the exhaust gas still has odors and high humidity after single spray treatment, making the discharged exhaust gas cleaner. Moreover, the filter plate 30 is fixed to the mounting plate 31 on the top of the processing box 27 by bolts, and the disassembly and installation operations are simple. Cleaning or replacement can be completed without complicated tools, reducing the difficulty and cost of equipment maintenance, and making it suitable for long-term high-frequency use scenarios.
