Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0019] like Figure 1-11 As shown, the present application provides an exhaust gas absorption and treatment device for flavor and fragrance production, comprising: An exhaust gas treatment box 1, wherein both ends of the exhaust gas treatment box 1 are connected to an air inlet 2 and an air outlet 3, and a first fixing plate 8 is provided inside the air inlet 2 and the air outlet 3. A second motor 9 is installed on one side of each first fixing plate 8, and the output end of the second motor 9 passes through the first fixing plate 8 and is connected to a plurality of fan blades 10 distributed in a circumference; In this embodiment, two groups of multiple fan blades 10 rotate in opposite directions through the corresponding second motor 9, so that the exhaust gas enters through the air inlet 2, is processed inside the exhaust gas treatment box 1, and is discharged through the air outlet 3.

[0020] Specifically, such as Figure 2 As shown, the exhaust treatment box 1 is provided with at least one set of filter plates 7 for filtering the exhaust gas, and an adsorbent filter layer 6 is provided on one side of the filter plate 7, and the adsorbent filter layer 6 is provided on the side close to the gas outlet 3; In this embodiment, the tail gas is filtered through the filter plate 7 to filter out the materials contained in the tail gas, and then passes through the adsorption treatment of the adsorbent filter layer 6 to adsorb the harmful substances in the tail gas.

[0021] Specifically, such as Figure 2 As shown, at least one set of mounting brackets 11 is installed at the inner top of the exhaust gas treatment box 1 near the air inlet 2. The cross section of the mounting bracket 11 is a hat-shaped structure, and a filter plate 7 is inserted into the interior of the mounting bracket 11. A first return spring 13 is provided between the top of the filter plate 7 and the inner top of the mounting bracket 11. The bottom of the filter plate 7 is in elastic contact with the inner bottom end of the exhaust gas treatment box 1 through the first return spring 13. In this embodiment: the elastically arranged filter plate 7 is in elastic contact with the inner bottom end of the exhaust gas treatment box 1, dividing the exhaust gas treatment box 1 into a material filtration chamber and an exhaust gas treatment chamber. Under the obstruction of the filter plate 7, unfiltered material cannot pass into the other chamber, thereby ensuring the exhaust gas treatment effect.

[0022] Specifically, such as Figure 2 and Figure 4 As shown, an exhaust gas absorption treatment device for flavor and fragrance production includes a scraping assembly for scraping off materials adhering to a filter plate 7.

When the mounting rod 17 moves up and down, the elastically arranged cleaning rod 20 can scrape the surface of the filter plate 7 to remove the adhered material. The return groove 23 is opened in a U-shaped structure. When the mounting rod 17 moves downward, it slides down along the return groove 23 on the side close to the filter plate 7 to scrape off the adhered material. When the mounting rod 17 moves upward, it moves up along the return groove 23 on the side away from the filter plate 7. At this time, the elastically arranged cleaning rod 20 does not contact the surface of the filter plate 7, ensuring that the material will not accumulate on the upper surface of the cleaning rod 20.

[0023] Specifically, such as Figure 4-Figure 5 as well as Figure 8-Figure 9 As shown, a rotating shaft 45 is rotatably provided on the side wall of the exhaust gas treatment box 1 at a position corresponding to the other side wall of the filter plate 7. One end of the rotating shaft 45 passes through the side wall of the exhaust gas treatment box 1 and is connected to a driving device. The rotating shaft 45 is rotatably provided inside the exhaust gas treatment box 1 by the driving device. At least one set of connecting plates 46 is mounted on the rotating shaft 45. A fourth receiving groove 41 is defined at one end of the connecting plate 46 away from the rotating shaft 45. A strike plate 42 is inserted into the fourth receiving groove 41. A seventh return spring 47 is disposed between the top end of the fourth receiving groove 41 and the end of the strike plate 42. In this embodiment, when the rotating shaft 45 rotates, it will drive the elastically arranged impact plate 42 to continuously impact the side wall of the filter plate 7, so as to shake off the materials adhering to the side wall of the filter plate 7.

[0024] Specifically, such as Figure 10 As shown, a fifth receiving groove 43 is provided on the side wall of the exhaust gas treatment box 1 at a position corresponding to the connecting plate 46.

Multiple sets of spaced-apart second return springs 16 are provided between the fixing rod 15 and the upper end of the mounting rod 17. The mounting rod 17 elastically slides inside the return groove 23 via the multiple sets of second return springs 16. A second receiving groove 24 is formed at the inner bottom end of the circular groove 23 near the side wall of the filter plate 7. A supporting rod 26 is inserted into the inner portion of the second receiving groove 24, and a fourth return spring 25 is provided between the end of the supporting rod 26 and the inner side wall of the second receiving groove 24. A clearance groove 21 is formed on the side wall of the exhaust treatment box 1 at a position above the meandering groove 23. The clearance groove 21 is connected to the meandering groove 23. A second airbag 22 is disposed inside the clearance groove 21. A third exhaust duct 48 is formed between the second airbag 22 and the sixth airbag 49. The second airbag 22 is connected to the sixth airbag 49 through the third exhaust duct 48. In this embodiment, the driving device connected to the rotating shaft 45 is started, driving the elastically arranged impact plate 42 to continuously beat the side wall of the filter plate 7, shaking off the adhered material. At the same time, the squeezing block 44 is squeezed, and the sixth airbag 49 on one side of the squeezing block 44 is compressed. The gas inside the sixth airbag 49 is discharged to the second airbag 22 through the third exhaust pipe 48. The second airbag 22 expands and pushes the mounting rod 17 downward along the meandering groove 23 through the second limit block 50. At this time, the elastically arranged cleaning rod 20 can scrape off the material adhered to the surface of the filter plate 7. When the second limit block 50 moves down along the side of the return groove 23 close to the filter plate 7 to the position of the elastically provided supporting rod 26, the second limit block 50 is supported to the side of the return groove 23 away from the filter plate 7 by the elastically provided supporting rod 26. At this time, the connecting plate 46 and the extrusion block 44 are staggered, the sixth airbag 49 is no longer compressed, and the second airbag 22 no longer supports the second limit block 50. At this time, under the action of the second return spring 16, the mounting rod 17 moves up along the return groove 23 and moves to below the second airbag 22.

[0025] Specifically, such as Figure 7 As shown, the bottom of the exhaust gas treatment box 1 is connected to a material discharge port 4 at a position corresponding to the bottom of the filter plate 7.

The output end of the first motor 5 passes through the bottom of the exhaust treatment box 1 and is connected to the third receiving groove 34. A pull rope 36 is provided between the output end of the first motor 5 and the side wall of the baffle 33. In this embodiment, the connection between the exhaust treatment box 1 and the material discharge port 4 is sealed by an elastically arranged baffle 33 to prevent exhaust gas from being discharged. When the material needs to be discharged, the first motor 5 is started, and the first motor 5 drives the baffle 33 to move through the pull rope 36.

[0026] Specifically, such as Figure 6 As shown, a limiting groove 37 is provided at the inner bottom end of the third receiving groove 34, and a first limiting block 38 is slidably provided inside the limiting groove 37, and the first limiting block 38 is connected to the lower end of the baffle 33; A fourth airbag 39 is provided between the side wall of the first limiting block 38 and the side wall of the limiting groove 37 away from the first motor 5 ; A first airbag 12 is provided between the inner top of the mounting frame 11 and the top of the filter plate 7 , and a first exhaust duct 14 is provided between the first airbag 12 and the fourth airbag 39 ; In this embodiment: after the filtration is completed, the first motor 5 is started, and the first motor 5 drives the baffle 33 to move through the pull rope 36. At this time, the fourth airbag 39 is no longer compressed, and the elastically arranged filter plate 7 rises under the action of the first return spring 13.

At the same time, the squeezing block 44 is squeezed, and the sixth air bag 49 on one side of the squeezing block 44 is compressed. The internal gas of the sixth air bag 49 is discharged to the second air bag 22 through the third exhaust pipe 48. The second air bag 22 expands and pushes the mounting rod 17 down along the return groove 23 through the second limit block 50. At this time, the elastically arranged cleaning rod 20 can scrape off the material adhered to the surface of the filter plate 7, and the scraped material falls On one side of the push plate 28, when the scraped material needs to be cleaned, the first motor 5 is started, and the first motor 5 drives the baffle 33 to move through the pull rope 36. At this time, the fourth airbag 39 is no longer compressed, and the elastically arranged filter plate 7 rises under the action of the first return spring 13. At the same time, the fifth airbag 40 is compressed, and the internal gas of the fifth airbag 40 is discharged to the third airbag 31 through the second exhaust pipe 32. The third airbag 31 expands and pushes the push plate 28 to move, pushing the material scraped from the filter plate 7 to the top of the material discharge port 4 and discharged through the material discharge port 4.
