[0019] like Figure 1-3 As shown, the present application provides a collection device for fermentation tail gas emissions, including a collection tank assembly 1 and an anti-backflow assembly 2, the collection tank assembly 1 includes a collection tank body 101, the anti-backflow assembly 2 includes a backflow shell 201 fixedly connected to the collection tank body 101, one side of the backflow shell 201 is fixedly connected to a ventilation pipe 202, the interior of the backflow shell 201 is fixedly connected to a limiting plate 207, one side of the limiting plate 207 is movably connected to four positioning rods 205, one side of the four positioning rods 205 is fixedly connected to a sealing disk 204, and the outer walls of the four positioning rods 205 are provided with reset elastic members 206.

[0020] One side of the limiting plate 207 is movably connected with the filter plate assembly 203, the top of the backflow shell 201 is provided with a withdrawal groove, the filter plate assembly 203 includes a water absorption plate 2031, the top of the water absorption plate 2031 is fixedly connected with a plug plate 2032, the top of the plug plate 2032 is fixedly connected with a top plate 2033, both sides of the top plate 2033 are provided with positioning blocks 2034 fixedly installed with the backflow shell 201, the tops of the two positioning blocks 2034 are fixedly connected with rotating shafts 2035, the outer walls of the two rotating shafts 2035 are rotatably connected with rotating plates 2036, and the middle parts of the two rotating plates 2036 are provided with tension spring rods 2037.

[0021] A wind tunnel is opened in the middle of the limiting plate 207, and the ratio of the diameter of the wind tunnel to the diameter of the sealing disk 204 is 1:2.

[0022] The ventilation pipe 202 is connected to the fermentation tank. The top of the collection tank body 101 is fixedly connected with a connector 102 . The connector 102 is connected to an external processing device. A switch is provided on the connector 102 .

[0023] The size of the extraction slot matches the size of the plug board 2032 .

[0024] Working principle:

[0025] Before using the device, first check the various components of the device to ensure that the various components of the device cooperate properly and ensure that the device can work normally.

[0026] When the device is in use, the exhaust gas generated inside the fermentation tank enters the backflow housing 201 through the ventilation pipe 202. When the exhaust gas enters and passes through the water absorption plate 2031, the water absorption plate 2031 filters the moisture inside the exhaust gas, and the exhaust gas continues to move, pushing open the sealing disk 204. The movement of the sealing disk 204 drives the four positioning rods 205 to move. The movement of the sealing disk 204 stretches the reset elastic member 206. The sealing disk 204 moves so that it is no longer on the sealing limiting plate 207. The exhaust gas enters the collection tank body 101 through the anti-backflow component 2 for collection. When the air pressure in the collection tank body 101 is equal to the air pressure inside the fermentation tank, the four reset elastic members 206 drive the sealing disk 204 to reset to achieve sealing.

[0027] When the water vapor adsorbed on the surface of the water absorption plate 2031 becomes too much and needs to be replaced, the user pulls up the two tension spring rods 2037 and rotates the tension spring rods 2037. The tension spring rods 2037 electrically rotate the rotating plate 2036 on the rotating shaft 2035 so that it is no longer on the positioning top plate 2033. The top plate 2033 is pulled out so that the top plate 2033 drives the plug plate 2032 and the water absorption plate 2031 to move, and the user replaces the water absorption plate 2031.

[0028] By providing the anti-backflow component 2, the anti-backflow component 2 can be sealed in time after the air pressure in the collecting tank body 101 is equal to that in the fermentation tank, so as to prevent the waste gas inside the collecting tank body 101 from flowing back into the fermentation tank and affecting the normal operation of the fermentation tank. At the same time, by providing the filter plate component 203, the moisture in the waste gas can be absorbed to prevent the water vapor from accumulating at the bottom of the collecting tank body 101.
