[0025] The following describes a gas collecting device for a fermenter provided by some embodiments of the present utility model with reference to the accompanying drawings.

[0026] Embodiment 1:

[0027] Combined with Figures 1-4 As shown, a gas collecting device for a fermenter provided by the present utility model includes a gas collecting mechanism 100, a gas delivery mechanism 200 and a dehumidifying mechanism 300. The gas collecting mechanism 100 includes a collecting bottle 110, a hose 120 connected and communicated with the collecting bottle 110, a vacuum generator 130 connected and communicated with the hose 120, and an air intake pipe 140 connected and communicated with the vacuum generator 130;

[0028] The gas delivery mechanism 200 includes a sealing box 210 sleeved on the outer end of the air intake pipe 140, a hopper cover 220 connected to the inner wall of the sealing box 210 and internally communicated with the air intake pipe 140, a gas collecting pipe 230 installed inside the hopper cover 220, and a rubber rod 240 inserted into the hopper cover 220;

[0029] The dehumidifying mechanism 300 includes a cylinder 310 connected between the sealing box 210 and the rubber rod 240, a plurality of rubber sheets 320 sleeved on the outer side of the rubber rod 240, an EPE 330 installed on one side of the rubber sheet 320, and a gauze 340 embedded at the bottom of the hopper cover 220. The outer wall of the rubber sheet 320 is attached to the inner wall of the air intake pipe 140.

[0030] Furthermore, one end of the rubber rod 240 extends into the air intake pipe 140 movably, and the other end of the rubber rod 240 extends into the sealing box 210 movably. With this structural design, it can prevent the gas in the fermenter from leaking between the hopper cover 220 and the rubber rod 240.

[0031] Further, the rubber sheet 320 is arranged in a C shape, and the notches of the rubber sheet 320 face upward and downward respectively. With this layout design, the flow path of the gas in the fermentation tank can be planned, the gas flow path can be increased, and the moisture in the gas can be completely absorbed by the EPE 330.

[0032] Further, the thickness of the EPE 330 is greater than that of the rubber sheet 320. With this size design, the ability of the EPE 330 to absorb moisture is guaranteed.

[0033] Embodiment 2:

[0034] Combined with Figures 1-4 As shown, on the basis of Embodiment 1, a plurality of threaded holes are provided on the sealing box 210, and the plurality of threaded holes are arranged in a matrix. The threaded holes are provided to facilitate the connection between the sealing box 210 and the external fermentation tank.

[0035] Embodiment 3:

[0036] Combined with Figures 2-4 As shown, in the above embodiment, a sleeve is installed at the bottom of the sealing box 210, and the bottom end of the gas collecting pipe 230 penetrates through the top end of the sleeve. The sleeve is provided to facilitate the gas in the external fermentation tank to enter the inside of the gas collecting pipe 230.

[0037] The working principle and usage process of the present utility model: When the device is put into actual use, the sleeve is communicated with the inside of the external fermentation tank, and then the vacuum generator 130 is started. The vacuum generator 130 indirectly makes the inside of the gas collecting pipe 230 in negative pressure, and then extracts the gas in the fermentation tank. The gas flows through the gas collecting pipe 230, the hopper cover 220, the connecting pipe 140, the vacuum generator 130, and the hose 120, and then enters the collecting bottle 110. In this process, the gas passes through a plurality of EPEs 330, and then the moisture is absorbed by the EPEs 330, so that the collecting bottle 110 receives dry gas. Here, the movable end of the cylinder 310 contracts regularly, and then the rubber rod 240 drives the rubber sheet 320 and the EPE 330 to move. When the rubber sheet 320 passes through the hopper cover 220, it will be bent by the hopper cover 220, and then the EPE 330 is clamped between the rubber rod 240 and the rubber sheet 320, so that the moisture in the EPE 330 is squeezed out. The squeezed water falls into the sealing box 210 from the position of the gauze 340. Then, the movable end of the cylinder 310 is controlled to extend, so that the rubber sheet 320 and the EPE 330 return to the initial position to ensure the moisture collection effect.

[0038] Although the embodiments of the present utility model have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present utility model. The scope of the present utility model is defined by the claims and their equivalents.
