Description

Technical Field

[0001] This utility model relates to the field of turpentine processing technology, specifically a turpentine processing exhaust gas purification device. Background Technology

[0002] Turpentine is a liquid extracted from the resin of coniferous plants through distillation or other methods. Its main component is terpenes. Turpentine is miscible with chloroform, ether, or acetic acid in any proportion, but it is insoluble in water. Turpentine is a high-flash-point flammable liquid, highly volatile, and produces a large amount of dense smoke when burned. Currently, due to its volatility, turpentine processing generates toxic, odorous, and harmful exhaust gases. Therefore, exhaust gas purification devices are typically installed at the exhaust or ventilation ports of turpentine processing equipment.

[0003] For example, the patent with authorization announcement number CN220696351U describes an exhaust gas treatment mechanism for turpentine processing equipment. Through the coordinated arrangement of a dry purification pipe, filter screen, activated carbon purification layer, humidification treatment box, partition, liquid supply pipe, spray head, and pipeline, the length of the dry purification pipe is extended to the maximum extent while ensuring that the volume of the treatment device remains unchanged. The dry purification pipe is multi-bent and multiple filter screens and activated carbon purification layers are added to improve the dry purification effect of the exhaust gas.

[0004] However, the above-mentioned device still has shortcomings. After the device has purified the exhaust gas for a long time, the filter element inside the device needs to be cleaned and replaced regularly. During the treatment process, the exhaust gas is usually directly cut off. However, in actual use, there will be untreated exhaust gas between the air inlet pipe and the filter element, which will cause untreated exhaust gas to leak during the filter element replacement process.

[0005] Based on this, a turpentine processing exhaust gas purification device is now provided, which can eliminate the drawbacks of existing devices. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0026] In one embodiment, such as Figures 1-5As shown, a turpentine processing exhaust gas purification device includes a device housing 1, an air inlet pipe 2, and an exhaust pipe 3. One end of the air inlet pipe 2 is connected to an activated carbon purification mechanism 4, and an air valve 10 is provided between the air inlet pipe 2 and the activated carbon purification mechanism 4. A fixing component 11 is movably provided at the top of the activated carbon purification mechanism 4. An extraction mechanism 9 is provided on one side of the activated carbon purification mechanism 4. The activated carbon purification mechanism 4 is connected to the extraction mechanism 9 through an extraction pipe 7. A sealing mechanism 8 is provided at the connection position between the extraction mechanism 9 and the extraction pipe 7.

[0027] In this embodiment, by means of the cooperation between the extraction mechanism 9 and the sealing mechanism 8, when the filter element needs to be replaced after long-term use, the gas valve 10 is first operated to close the connection channel, then the extraction mechanism 9 is controlled to extract the untreated exhaust gas, and then the fixing component 11 is disassembled to open the activated carbon purification mechanism 4 to replace the internal filter element and prevent the leakage of untreated harmful exhaust gas.

[0028] In one embodiment, such as Figure 2 As shown, the activated carbon purification mechanism 4 includes a filter pipe 401, a mounting base 403 is fixedly installed inside the filter pipe 401, an activated carbon filter element 404 is movably installed on the mounting base 403, and a collection channel 402 is connected to one end of the filter pipe 401 near the air inlet pipe 2. The extraction pipe 7 is connected to the collection channel 402. When the device is closed and the gas stops flowing, the untreated harmful exhaust gas will accumulate in the collection channel 402.

[0029] In one embodiment, such as Figure 2 and Figure 4 As shown, the extraction mechanism 9 includes a temporary storage box 901. A pull rod 902 is slidably connected to the middle of the temporary storage box 901. Several fixing holes 904 are longitudinally opened on the pull rod 902. A sealing element 903 is fixedly connected to the bottom end of the pull rod 902. A handle 906 is connected to the top end of the pull rod 902 to the outside of the temporary storage box 901. A fixing rod 905 is provided in the temporary storage box 901 near the pull rod 902. The fixing rod 905 matches the fixing holes 904. Removing the fixing rod 905 releases the lock of the pull rod 902. At this time, pulling the handle 906 can drive the sealing element 903 to rise. Then, the fixing rod 905 is inserted back to keep the pull rod 902 locked.

[0030] In one embodiment, such as Figure 2 and Figure 5As shown, the sealing mechanism 8 includes a first sealing block 801, which is disposed inside the temporary storage box 901. A pair of first sliding rods 802 are fixedly connected to the bottom side of the first sealing block 801. The first sliding rods 802 extend through the temporary storage box 901 to the outside and are slidably connected to the temporary storage box 901. A limiting ring 804 is connected between the two first sliding rods 802. The limiting ring 804 is sleeved with the extraction tube 7. A first spring 803 is wound around the surface of the first sliding rod 802. The two ends of the first spring 803 are respectively connected to... The limiting ring 804 and the temporary storage box 901 are connected. The first sealing block 801 has a through hole 805 in the middle. The first sealing block 801 is provided with a second sealing component. When the sealing element 903 is raised, a negative pressure is generated between the sealing element 903 and the first sealing block 801. The pressure pushes the first sealing block 801 to rise, so that the gas enters the temporary storage box 901 from the extraction pipe 7. At the same time, the first sliding rod 802 is raised, which drives the limiting ring 804 to squeeze the first spring 803. When there is no pressure, the first sealing block 801 is reset under the reset action of the first spring 803.

[0031] In one embodiment, such as Figure 2 and Figure 5 As shown, the second sealing assembly includes a second sealing block 806, which is disposed at the bottom of the through hole 805. A pair of second sliding rods 807 are connected to the top side of the second sealing block 806. The two second sliding rods 807 pass through the first sealing block 801 and are slidably connected to the first sealing block 801. A limiting plate 809 is connected between the two second sliding rods 807. A second spring 808 is wound around the surface of the second sliding rod 807. The two ends of the second spring 808 are respectively connected to the limiting plate 809 and the first sealing block 801. When the sealing member 903 descends, it will squeeze the first sealing block 801. Gas passes through the through hole 805 and squeezes the second sealing block 806. At this time, the second sealing block 806 is pressured and moves downward, so that gas passes through. At this time, the second sliding rods 807 slide along and drive the limiting plate 809 to squeeze the second spring 808. When there is no pressure, the second sealing block 806 resets under the action of the second spring 808 and re-blocks the through hole 805.

[0032] In one embodiment, such as Figure 5 As shown, the surface of the sealing element 903 is provided with a sealing material, the bottom of the first sealing block 801 is provided with a sealing gasket, and the top of the second sealing block 806 is provided with a sealing gasket to increase the sealing degree and prevent gas leakage.

[0033] In one embodiment, such as Figure 1 and Figure 3As shown, the top side of the activated carbon purification mechanism 4 is connected to a conveying pipe 6, and the other end of the conveying pipe 6 is connected to a wet treatment mechanism 5, which adopts a combination of dry purification and wet purification to improve filtration efficiency.

[0034] In one embodiment, such as Figure 3 As shown, the wet treatment mechanism 5 includes a wet treatment tank 501. The top of the wet treatment tank 501 is connected to an infusion pipe 504. One end of the infusion pipe 504 passes through the wet treatment tank 501 and is connected to a connecting pipe 502. Several spray heads 503 are provided on the lower surface of the connecting pipe 502. A drain pipe 505 is provided at the bottom of the wet treatment tank 501. The infusion pipe 504 is connected to a glacial acetic acid solution, and the solution is injected into the connecting pipe 502 and sprayed out by the spray heads 503, thereby humidifying and filtering the exhaust gas and improving the filtration effect. Glacial acetic acid is used as the absorbent because it has the effect of efficiently absorbing and dissolving α-pinene and β-pinene in turpentine oil.

[0035] The above embodiment discloses a turpentine processing exhaust gas purification device. When the filter element needs to be replaced after long-term use, firstly, operate the air valve 10 to close the connection channel. Untreated harmful exhaust gas will accumulate in the collection channel 402. Remove the fixing rod 905 to release the lock of the pull rod 902. At this time, pulling the handle 906 can lift the sealing element 903. When the sealing element 903 lifts, a negative pressure is generated between the sealing element 903 and the first sealing block 801. This pressure pushes the first sealing block 801 to lift, allowing gas to enter the temporary storage box 901 from the extraction pipe 7. Simultaneously, the first sliding rod 802 lifts, causing the limiting ring 804 to compress the first spring 803. When there is no pressure, the first sealing block... 801 is reset under the reset action of the first spring 803 and resealed. At this time, the fixing rod 905 is inserted back to keep the pull rod 902 locked. After the filter element is replaced, the control pull rod 902 drives the sealing element 903 to descend. When the sealing element 903 descends, it will squeeze the first sealing block 801. The gas squeezes the second sealing block 806 through the through hole 805. At this time, the second sealing block 806 is pressured and moves downward, so that the gas can pass through. At this time, the second sliding rod 807 slides along and drives the limiting plate 809 to squeeze the second spring 808. When there is no pressure, the second sealing block 806 is reset under the action of the second spring 808 and re-blocks the through hole 805 to prevent the leakage of untreated harmful exhaust gas.

[0036] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
