For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0055] The embodiments of the present application will be described in detail below.

[0056] Embodiment 1

[0057] Referring to Figures 1-3The embodiment provides a fermentation tank facilitating sampling, which comprises a tank body 1, an ammonia water pipe 2, a stirring mechanism, a feeding pipe 4, a measuring cup 5, a gas pipe 6, a flexible buffering mechanism 7, a sampling pipeline 81, a steam pipeline 82 and a condensed water recovery pipe 83.

[0058] The lower side wall of the tank body 1 is provided with a feeding interface 11 and a sampling interface 12. One end of the feeding interface 11 extends into the tank body 1 and is flared.

[0059] The outlet of the ammonia water pipe 2 is close to the inner bottom of the tank body 1.

[0060] The stirring mechanism comprises a stirring shaft 31 located in the tank body 1 and a plurality of stirring blades 32 arranged at intervals along the length direction of the stirring shaft 31. The feeding interface 11 is located below the stirring blades 32.

[0061] The feeding pipe 4 is connected with the inlet of the measuring cup 5, and the feeding pipe 4 is provided with a first electric control valve 41.

[0062] The outlet of the measuring cup 5 is connected with the feeding interface 11 through a pipeline 51, and the pipeline 51 is provided with a second electric control valve 52.

[0063] The gas pipe 6 is connected with the inlet of the measuring cup 5, and pressure gas is introduced into the measuring cup 5 through the gas pipe 6 to control the feeding pressure.

[0064] The flexible buffering mechanism 7 is connected with the flared end of the feeding interface 11 and is located on the discharging path of the feeding interface 11.

[0065] The sampling pipeline 81 is connected with the sampling interface 12.

[0066] The steam pipeline 82 is connected with the pipeline 51 and the sampling pipeline 81.

[0067] The condensed water recovery pipe 83 is connected with the sampling pipeline 81.

[0068] Through the arrangement of the measuring cup 5, the liquid to be introduced into the tank body 1 can be quantified, and then the orderly opening and closing of the first electric control valve 41 and the second electric control valve 52 and the scheme of introducing the gas with the specified pressure into the gas pipe 6 are adopted to realize the control of the feeding speed and the feeding amount.

[0069] Since one end of the feeding interface 11 extends into the tank body 1 and is flared, the diameter of the outlet of the feeding interface 11 changes greatly, so that the flow rate of the liquid can be effectively slowed down and the impact of the liquid on the inner wall of the tank body 1 is weakened, thereby reducing the generation of bubbles.

[0070] Through the arrangement of the flexible buffering mechanism 7, the partial impact force of the liquid can be absorbed, and the impact of the liquid on the inner wall of the tank body 1 is further weakened, thereby reducing the generation of bubbles.

[0071] The outlet of ammonia water pipe 2 is close to the bottom of the inner side of tank 1, so that the outlet of ammonia water pipe 2 can be located below the liquid surface inside tank 1. In this way, there will be no situation where ammonia water is pumped away before it enters the liquid, thus avoiding waste of ammonia water.

[0072] By arranging multiple stirring blades 32 at intervals along the length of the stirring shaft 31, the overall stirring effect on the liquid inside the tank 1 is enhanced. By positioning the feed inlet 11 below the stirring blades 32, the liquid entering the tank 1 through the feed inlet 11 can be rapidly stirred by the stirring blades 32 and mixed evenly with other liquids in the tank as it flows upward.

[0073] By adding a steam pipe 82, which is connected to the conduit 51 and the sampling pipe 81, the high-temperature steam can sterilize the sampling pipe 81 before sampling and sterilize the measuring cup 5 and its supporting pipelines before feeding, so as to prevent the sample and liquid from being contaminated.

[0074] The steam used in the sampling pipe 81 can be recycled after condensation and enter the condensate recovery pipe 83.

[0075] Example 2

[0076] See Figures 1-3 In this embodiment, the flexible buffer mechanism 7 includes a support plate 71 and a flexible protrusion 72.

[0077] The support plate 71 is connected to the feed interface 11 via a connecting assembly.

[0078] A flexible protrusion 72 is located on the side of the support plate 71 facing the feed inlet 11, and the side of the flexible protrusion 72 facing the feed inlet 11 is spherical. The flexible protrusion 72 is like an airbag, and an air nozzle 73 is connected to the flexible protrusion 72. A pressure relief valve 731 is provided on the air nozzle 73.

[0079] The flexible protrusion 72 deforms when impacted by the liquid, consuming some of the liquid's kinetic energy, thereby reducing the impact of the liquid on the inner wall of the tank 1 during feeding and reducing the generation of bubbles.

[0080] By making the flexible protrusion 72 spherical on the side facing the feed inlet 11, it can not only provide a good buffering effect, but also guide and disperse the liquid.

[0081] Considering the high temperature inside the fermenter, the expansion of the gas inside the flexible protrusion 72 due to heat may reduce the elasticity of the flexible protrusion 72. Therefore, a pressure relief valve 731 is provided on the gas nozzle 73 to automatically release pressure when the gas pressure inside the flexible protrusion 72 reaches a threshold, so as to prevent the flexible protrusion 72 from being stretched too much and causing a decrease in the buffering effect.

[0082] The connecting assembly comprises a connecting sleeve 74 and a supporting rod 75.

[0083] The connecting sleeve 74 is screwed on the outer wall of the feed interface 11, and the connecting sleeve 74 is provided with an extension 76, and the extension 76 is provided with a limiting notch 77.

[0084] One end of the supporting rod 75 is hingedly connected to the connecting sleeve 74, and the other end of the supporting rod 75 is connected to the upper part of the supporting plate 71 after passing through the limiting notch 77.

[0085] Through the arrangement of the connecting sleeve 74 and the supporting rod 75, the supporting plate 71 is conveniently connected to the feed interface 11.

[0086] Further, the supporting rod 75 is hingedly connected to the supporting plate 71; when the gas pressure passing through the trachea 6 to the metering cup 5 is high, the supporting plate 71 can be pushed, so that the transverse distance between the flexible protrusion 72 and the feed interface 11 is increased, so that the liquid can avoid being subjected to excessive rebound force from the flexible protrusion 72.

[0087] Finally, it should be noted that: the above is only the preferred embodiment of the present application, and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations, and the embodiments of the present application and the features in the embodiments can be arbitrarily combined with each other without conflict. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
