[0031] Embodiment 1

[0032] Referring to Figure 1 - Figure 2 , the present utility model discloses an exhaust device for a fermentation workshop, including a workshop 1, and further including an exhaust device 2 fixed on the top of the workshop 1. The exhaust device 2 includes an exhaust duct 3 and an exhaust fan 4 connected to the exhaust duct 3. One end of the exhaust duct 3 is located outside the workshop 1, and the other end of the exhaust duct 3 is communicated with an adsorption hood 5 that swings above the interior of the workshop 1. Under the action of the exhaust fan 4, the odor-containing air in the workshop 1 will enter the exhaust duct 3 through the adsorption hood 5, and then be discharged from the end of the exhaust duct 3 located outside the workshop 1, making the air in the workshop 1 cleaner, and it is also less likely for workers in the workshop to smell odors such as fishy smell. The adsorption hood 5 is located above the inner cavity of the workshop 1, does not occupy the space below the workshop, and is not easily damaged.

[0033] Referring to Figure 3 - Figure 5, in this embodiment, a support plate 6 is horizontally fixed on the inner cavity side wall of the workshop 1. The exhaust duct 3 is connected to the support plate 6 through a plurality of pipe clamps 7, and the exhaust fan 4 is installed on the outer side wall of the workshop 1. The support plate 6 can be fixed on the cavity of the workshop 1 through expansion bolts, and is used to support the exhaust duct 3 and the structures above. The exhaust duct 3 is fixed on the support plate 6 through the pipe clamps 7 to ensure the stability of the connection. The exhaust fan 4 is installed outside the workshop 1 to reduce the noise of the exhaust fan 4 in the workshop 1.

[0034] In this embodiment, an extension duct 8 is integrally provided on the exhaust duct 3. The top of the extension duct 8 is connected to an adsorption duct 10 through a sealed bearing 9. Among them, the exhaust duct 3, the extension duct 8, and the adsorption duct 10 are all made of metal pipes. The outer ring of the sealed bearing 9 is fixed on the extension duct 8, and the inner ring is fixed to one end of the adsorption duct 10, so that the adsorption duct 10 can rotate on the extension duct 8. The corresponding length of the adsorption duct 10 can be selected according to the length in the workshop 1. A plurality of adsorption hoods 5 are evenly distributed below the adsorption duct 10, and multiple areas in the workshop 1 can be deodorized through the plurality of adsorption hoods 5. In order to increase the range of the adsorption hood 5 to adsorb the odor, an adjustment structure 11 is installed on the support plate 6, and the adsorption duct 10 is controlled to swing above the inside of the workshop 1 through the adjustment structure 11.

[0035] In this embodiment, the adsorption duct 10 includes a vertical section 1001 and a horizontal section 1002. A plurality of adsorption hoods 5 are connected and arranged below the horizontal section 1002. The bottom end of the vertical section 1001 of the adsorption duct 10 is connected to the extension duct 8 through a sealed bearing 9.

[0036] Specifically, in this embodiment, the adjustment structure 11 includes a driven bevel gear 1101 fixedly sleeved outside the vertical section 1001 of the adsorption pipeline 10. Both sides of the driven bevel gear 1101 are engaged with a driving bevel gear 1102, and one side of the driving bevel gear 1102 is coaxially connected with a driving gear 1103. It also includes a driving shaft 1104. The outer ends of both sides of the driving shaft 1104 are respectively fixedly sleeved with a first incomplete gear 1105 and a second incomplete gear 1106. The first incomplete gear 1105 is engaged and connected with one of the driving gears 1103, and the second incomplete gear 1106 is engaged and connected with the other driving gear 1103. When the driving shaft 1104 rotates clockwise, when the first incomplete gear 1105 is engaged with the driving gear 1103 on one side, the second incomplete gear 1106 is not engaged with the driving gear 1103 on the other side. At this time, the first incomplete gear 1105 drives the coaxial driving bevel gear 1102 to rotate counterclockwise through the driving gear 1103 on one side, and the driving bevel gear 1102 will drive the adsorption pipeline 10 to rotate clockwise through the driven bevel gear 1101. On the contrary, when the second incomplete gear 1106 is engaged with the driving gear 1103 on the other side, the first incomplete gear 1105 is not engaged with the driving gear 1103 on one side. At this time, the second incomplete gear 1106 drives the coaxial driving bevel gear 1102 to rotate counterclockwise through the driving gear 1103 on one side, and the driving bevel gear 1102 will drive the adsorption pipeline 10 to rotate counterclockwise through the driven bevel gear 1101. In this way, through the adjustment structure 11, the adsorption pipeline 10 can be driven to swing reciprocally above the inner cavity of the workshop 1 during the rotation of the driving shaft 1104, so as to realize the adsorption of odor in a larger area by the adsorption hood 5 below.

[0037] In addition, shaft seats 1107 are fixed on both sides of the top of the support plate 6. A first support shaft 1108 and a driving shaft 1104 are rotatably inserted into the shaft seats 1107. The driving bevel gear 1102 and the driving gear 1103 are sleeved outside the first support shaft 1108. The shaft seats 1107 are used to support the first support shaft 1108 and the driving shaft 1104 to ensure the stability of the meshing between gears. It also includes a reduction motor 1109 fixed on the support plate 6. The output end of the reduction motor 1109 is fixedly connected with the first end of the driving shaft 1104. Through the reduction motor 1109, the swing frequency of the adsorption pipeline 10 can be driven through the driving shaft 1104.

[0038] Working principle:

[0039] The staff installs the equipment above Workshop 1 through the lift. When it is necessary to remove the peculiar smell in Workshop 1, the exhaust fan 4 and the reduction motor 1109 are started. The reduction motor 1109 drives the first incomplete gear 1105 and the second incomplete gear 1106 to alternately engage with the driving bevel gears 1102 on both sides through the driving shaft 1104, so as to drive the adsorption pipeline 10 to swing reciprocally over the airspace in Workshop 1 through the driven bevel gear 1101. The peculiar smell in a larger area can be adsorbed through the multiple adsorption covers 5 at the bottom of the adsorption pipeline 10. Under the action of the exhaust fan 4, the peculiar smell air in Workshop 1 will enter the exhaust pipeline 3 through the adsorption cover 5, and then be discharged from one end of the exhaust pipeline 3 located outside Workshop 1, making the air in Workshop 1 cleaner, and it is also less likely for workers to smell peculiar smells such as fishy smell in the workshop.

[0040] Embodiment 2

[0041] Referring to Figure 5 - Figure 6 , based on the same concept as in the above Embodiment 1, the exhaust device for a fermentation workshop further includes that the adsorption cover 5 includes a cover body 501. A plurality of communication ports 1003 are evenly arranged at the bottom of the adsorption pipeline 10, and the top of the cover body 501 is connected to the communication port 1003. An adsorption layer 502 is embedded in the cover body 501; the adsorption layer 502 includes a zeolite molecular sieve layer and a nano black tourmaline layer. In other embodiments, the adsorption layer 502 can also use only one of the zeolite molecular sieve layer and the nano black tourmaline layer or other adsorption layers that can adsorb peculiar smells. The zeolite molecular sieve layer and the nano black tourmaline layer adopted in this embodiment both have good effects of adsorbing peculiar smells and can well remove peculiar smells such as fishy smell in the workshop.

[0042] Embodiment 3

[0043] Referring to Figure 2 , Figure 3 and Figure 6 , based on the same concept as in the above Embodiment 1, the exhaust device for a fermentation workshop further includes that one end of the exhaust pipeline 3 located outside Workshop 1 and the inner cavity bottom of the cover body 501 are both connected with a filter screen 503. The filter screen 503 can play a protective role to prevent large impurities such as plastic bags from entering the cover body 501 and causing blockage, and improve the exhaust effect; at the same time, it can also effectively prevent snakes and rats from entering the cover body 501 and causing blockage.

[0044] The above are all the preferred embodiments of the present invention. The protection scope of the present invention is not limited accordingly.
