Description

Technical Field

[0001] The utility model relates to the technical field of microbial fermentation, in particular to a biological fermentation device of a biological surfactant rhamnolipid. Background Art

[0002] Biosurfactants are a type of biodegradable surfactant that not only possesses the common properties of surfactants such as solubilization, emulsification, wetting, foaming, dispersion, and surface tension reduction.

[0003] For example, a bio-fermentation device for a biosurfactant rhamnolipid, disclosed in publication number CN211645258U, includes a fermentation tank, a control panel disposed on the outer surface of the fermentation tank, an input end of the control panel being electrically connected to an output end of an external power supply, and an annular electric heating plate disposed on the inner surface of the fermentation tank, an input end of the electric heating plate being electrically connected to an output end of a temperature control switch. The bio-fermentation device for the biosurfactant rhamnolipid improves the stirring effect through a stirring mechanism and a circulation device, transports the fermentation liquid deposited at the bottom of the fermentation tank to the upper portion of the fermentation tank, thereby ensuring normal fermentation and production. Meanwhile, a bubble recovery mechanism can recover the fermentation liquid that overflows in the form of foam into the fermentation tank for continued fermentation, thereby avoiding the loss of bacteria and nutrients in the culture medium, improving conversion efficiency and substrate utilization, and increasing surfactant production. Furthermore, contamination can be prevented, thereby improving product quality.

[0004] The above patent proposes that the fermentation liquid overflowing in the form of foam can be recovered into the fermentation tank through a bubble recovery mechanism to continue fermentation. However, in actual use, the foam is not processed, resulting in an excessively thick foam layer, which reduces the contact area between the gas and the culture medium, thereby reducing the solubility of oxygen, affecting the respiration and metabolic processes of the microorganisms, and further affecting the fermentation rate.

[0005] Therefore, we proposed a biological fermentation device of biosurfactant rhamnolipid to solve the above problems. Utility Model Content

A groove 53 is formed in the middle of one end of the external connecting rod 51 . The external connecting rod 51 is fixedly connected to the fermentation tank 41 .

[0025] The driving component 1 includes a limiting ring frame 11 and an inner limiting groove 12 opened at the middle end of the inner wall of the limiting ring frame 11. A connecting rod 44 is installed at one end of the fermentation tank 41, and a large gear 45 is installed on the outer surface of the connecting rod 44, and the large gear 45 is arranged inside the inner limiting groove 12. The cylinder 46 passes through the connecting rod 44 and one end of the fermentation tank 41. A sealing ring 47 is installed on the outer surface where the cylinder 46 connects with the connecting rod 44 and the fermentation tank 41. A small gear 15 is installed inside the inner limiting groove 12, and the small gear 15 is engaged with the large gear 45. A rotating shaft 14 is installed inside the small gear 15, and a driving motor 13 is installed at one end of the rotating shaft 14. The provided sealing ring 47 seals between the cylinder 46 and the fermentation tank 41.

[0026] The support member A3 includes a movably mounted connecting ring 32, a short support leg 31 is installed at the bottom end of the connecting ring 32, a bracket 2 is installed at the bottom end of the limiting ring frame 11, and the bottom end of the bracket 2 is flush with the bottom end of the short support leg 31. The support member A3 is set to support one end of the fermentation tank 41.

[0027] The support member B7 includes a fixing ring 72 sleeved inside the annular groove 52 and a long support leg 71 installed at the bottom end of the fixing ring 72. The support member B7 supports one end of the fermentation tank 41, and the fixing ring 72 rotates inside the annular groove 52.

[0028] In this embodiment: after the raw materials are placed inside the lower narrow arc groove 42, the driving motor 13 is operated, and the rotating shaft 14 drives the small gear 15 to rotate, and the large gear 45 engaged with the small gear 15 drives the connecting rod 44, the fermentation tank 41 and the external rod 51 to rotate. The fermentation tank 41 and the external rod 51 rotate inside the connecting ring 32 and the fixed ring 72 respectively. The rotating fermentation tank 41 drives the raw materials to be stirred inside the lower narrow arc groove 42 and the upper wide arc groove 43. When the fermentation tank 41 has completed rotation, the generated foam is inside the lower narrow arc groove 42 and the upper wide arc groove 43, and the cylinder 46 extends to push the moving block 48 to move inside the lower narrow arc groove 42 and the upper wide arc groove 43. The foam is pushed into the interior of the semicircular groove 49 by the moving block 48 to prevent the presence of foam from affecting the reaction efficiency between the raw materials.

[0029] Example 2: This example is an improvement based on Example 1. For details, please refer to Figure 2-Figure 4 The defoaming component 6 includes a defoaming motor 61 and a connecting shaft 62 mounted on the output end of the defoaming motor 61. A rotating plate 63 is mounted on the outer surface of the connecting shaft 62, and needles 64 are mounted on both sides of the rotating plate 63. The defoaming motor 61 is disposed within the receiving groove 53. The foam is pushed into the semicircular groove 49 by the moving block 48. The rotating plate 63 rotates back and forth, driving the needles 64 to puncture the foam.

[0030] The moving block 48 includes a semicircular narrow frame 481 and a semicircular wide frame 482 installed on the top of the semicircular narrow frame 481. A built-in bar 484 is installed inside the semicircular narrow frame 481. A filter screen 483 is installed between the top of the built-in bar 484 and the semicircular wide frame 482. A vertical bar 485 is installed between the bottom end of the built-in bar 484 and the semicircular narrow frame 481. The outer surfaces of the semicircular narrow frame 481 and the semicircular wide frame 482 fit the inner walls of the lower narrow arc groove 42 and the upper wide arc groove 43.

[0031] In this embodiment: when the moving block 48 moves inside the lower narrow arc groove 42 and the upper wide arc groove 43, the filter screen 483 will push the foam to move, and the raw liquid will flow to one side of the sealing ring 47 through the filter screen 483. The provided semicircular narrow frame 481 and the vertical bar 485 continue to mix the raw liquid inside the lower narrow arc groove 42. After the foam enters the interior of the semicircular groove 49, the defoaming motor 61 starts to operate, and the connecting shaft 62 drives the rotating plate 63 to rotate inside the semicircular groove 49. The needles 64 provided on both sides of the rotating plate 63 puncture the foam. The raw liquid after the foam is broken flows through the filter screen 483 into the raw liquid inside the lower narrow arc groove 42 to avoid foam remaining in the raw liquid. After the foam inside the semicircular groove 49 is eliminated, the cylinder 46 contracts, and after the moving block 48 has moved to one side of the sealing ring 47, the above operation can be repeated to collect and eliminate the foam.

[0032] Working principle: the fermentation tank 41 and the external rod 51 rotate inside the connecting ring 32 and the fixed ring 72 respectively, and the raw materials are stirred inside the lower narrow arc groove 42 and the upper wide arc groove 43. When the fermentation tank 41 has finished rotating, the cylinder 46 extends to push the moving block 48 to move inside the lower narrow arc groove 42 and the upper wide arc groove 43, and the filter screen 483 pushes the foam to move. The raw liquid flows to one side of the sealing ring 47 through the filter screen 483, and the defoaming motor 61 starts to operate. The connecting shaft 62 drives the rotating plate 63 to rotate inside the semicircular groove 49. The needles 64 arranged on both sides of the rotating plate 63 puncture the foam. The raw liquid after the foam is broken flows through the filter screen 483 into the raw liquid inside the lower narrow arc groove 42, so as to avoid the presence of foam affecting the reaction efficiency between the raw materials.
