Description

Technical Field

[0001] This application relates to the technology of strain inoculation, and particularly to a protection device for strain inoculation in a fermenter. Background Art

[0002] In the process of microbial fermentation, after the strains are successfully cultivated in a conical flask, they need to be transferred to a fermenter for scale-up cultivation. Among them, during the strain inoculation process of the fermenter, in order to prevent miscellaneous bacteria from entering the fermenter, operations are usually carried out under the protection of a flame.

[0003] Currently, a commonly used flame protection method is as follows: First, the staff places alcohol cotton around the inoculation port of the fermenter, then ignites the alcohol cotton, and the alcohol cotton burns for protection. Then, the sealing cover threadedly connected to the inoculation port is opened, and the strains in the conical flask are poured into the fermenter through the inoculation port from the middle of the flame. After that, the inoculation port is sealed with the sealing cover, and finally, a wet cloth is directly covered on the alcohol cotton to extinguish the flame. However, when extinguishing the flame in the above method, usually two wet cloths are required to completely extinguish the flame, which not only makes the operation complex, but also the staff is easily exposed to the flame and scalds their hands. Summary of the Utility Model

[0029] To make the objectives, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts also belong to the scope of protection of the present application.

[0030] As Figures 1 - 5 shown:

[0031] A fermentation tank strain inoculation protection device provided by an embodiment of the present application includes an annular box 1, and alcohol is contained inside the annular box 1.

[0032] An annular combustion structure 2 that extends into the annular box 1 and can absorb alcohol is installed at the upper end of the annular box 1. When the annular combustion structure 2 absorbs alcohol, the alcohol wets the annular combustion structure 2, so the alcohol can be ignited and burned at the position of the annular combustion structure 2.

[0033] An annular sealing cover 3 is detachably and sealingly connected to the upper end of the annular box 1, and the annular combustion structure 2 is located inside the sealing cover 3.

[0034] Both the annular box 1 and the sealing cover 3 are fixed with handles (4, 5). Specifically, handles are fixed on the outer ring walls of the annular box 1 and the sealing cover 3.

[0035] In this embodiment, the annular box 1 includes an annular groove 101 with an open upper end. A cover plate 102 is hermetically fixed to the upper end of the annular groove 101. The cover plate 102 is made of a high-temperature resistant transparent material, facilitating the observation of the alcohol storage amount in the annular box 1.

[0036] When inoculating the fermentation tank 15, first remove the sealing cover 3, then place the annular box 1 on the upper end of the fermentation tank 15. After the annular box 1 is sleeved on the inoculation port 16 of the fermentation tank 15, ignite the annular combustion structure 2 with an ignition tool (such as a match, lighter, etc.). The annular combustion structure 2 burns alcohol for flame protection. Then open the sealing cover 17 threadedly connected to the inoculation port 16, and pour the bacteria in the Erlenmeyer flask into the fermentation tank 15 through the inoculation port 16 from the middle of the flame. Then close the inoculation port 16 with the sealing cover 17. Finally, hold the handle 5 connected to the sealing cover 3 and cover the sealing cover 3 on the upper end of the annular box 1. At this time, the lower end of the sealing cover 3 fits with the upper end of the annular box 1, and the annular combustion structure 2 is located inside the sealing cover 3. Since the inside of the sealing cover 3 is a closed structure after the sealing cover 3 is covered on the upper end of the annular box 1, the annular combustion structure 2 is isolated from oxygen. Therefore, the flame of the alcohol combustion can be extinguished after the sealing cover 3 is covered on the upper end of the annular box 1. Finally, hold the handle 4 connected to the annular box 1 and transfer the annular box 1 to the position of the inoculation port 16 of the next fermentation tank 15 to continue the inoculation work.

[0037] When not in use, fixedly connect the sealing cover 3 to the annular box 1. At this time, the sealing cover 3 seals the annular combustion structure 2, which can not only prevent alcohol volatilization but also protect the annular combustion structure 2.

[0038] The fermentation tank bacteria inoculation protection device provided in this embodiment is provided with an annular box 1 filled with alcohol inside. An annular combustion structure 2 extending into the annular box 1 and capable of absorbing alcohol is provided at the upper end of the annular box 1. The upper end of the annular box 1 is detachably and hermetically connected with an annular sealing cover 3, and the annular combustion structure 2 is located inside the sealing cover 3. Both the annular box 1 and the sealing cover 3 are fixed with handles, so that when inoculating the fermentation tank 15, only need to hold the handle connected to the sealing cover 3 and cover the sealing cover 3 on the upper end of the annular box 1 to extinguish the flame. It is not only convenient to operate, but also when the staff holds the handle to cover the sealing cover 3, the hand is at a certain distance from the flame, thus avoiding the problem of the hand contacting the flame and being scalded.

[0039] In some embodiments of the present application, the annular combustion structure 2 is composed of two symmetrically distributed cotton ropes 201.

[0040] The cotton rope 201 includes an arc segment 202, and vertical segments 203 integrally formed therewith are provided at both ends of the arc segment 202. The arc segment 202 is horizontally fixed to the upper end of the annular box 1, and the vertical segments 203 penetrate through the upper end of the annular box 1 and extend into the interior of the annular box 1.

[0041] Furthermore, a plurality of U-shaped members 6 evenly distributed along the arc segment 202 are sleeved on the arc segment 202. The U-shaped members 6 are fixed to the upper end of the annular box 1, and the arc segment 202 is clamped between the U-shaped members 6 and the upper end of the annular box 1.

[0042] In this embodiment, the vertical segment 203 extends into the alcohol in the annular box 1 to absorb the alcohol in the annular box 1, and the arc segment 202 absorbs the alcohol on the vertical segment 203, thereby realizing the alcohol infiltration of the annular combustion structure 2.

[0043] In some embodiments of the present application, an annular sleeve 7 that tightly presses the vertical segment 203 is sleeved on the vertical segment 203. The annular sleeve 7 penetrates through the upper end of the annular box 1 and is hermetically connected to the upper end of the annular box 1, so as to prevent alcohol from leaking out at the position where the vertical segment 203 penetrates through the upper end of the annular box 1 after the annular box 1 tilts.

[0044] In some embodiments of the present application, in order to facilitate the addition of alcohol into the annular box 1, a liquid adding port 8 for adding alcohol is provided on the outer ring wall of the annular box 1. The liquid adding port 8 is threadedly connected with a plug 9 for plugging the liquid adding port 8.

[0045] When adding alcohol, the liquid adding port 8 is distributed upward for adding alcohol.

[0046] In some embodiments of the present application, annular plates 10 are hermetically fixed to both the upper end of the inner ring wall and the upper end of the outer ring wall of the annular box 1. There is a gap between the annular plates 10 and the upper end of the annular box 1, and two symmetrically distributed notches 11 are formed on the annular plates 10.

[0047] On the outer wall of the sealing cover 3, limiting blocks 12 equal in number to and corresponding one by one to the notches 11 are fixed, and each limiting block 12 can rotate from the corresponding notch 11 into the gap and tightly press the annular plate 10 and the annular box 1, that is, the limiting block 12 can rotate to the side of the notch 11 to tightly press the lower end of the annular plate 10 and the upper end of the annular box 1.

[0048] Among them, after the limiting block 12 rotates into the gap, the lower end of the sealing cover 3 tightly presses the upper end of the annular box 1.

[0049] In this embodiment, in order to facilitate placing the limiting block 12 at the position of the notch 11, the size of the notch 11 is larger than the size of the limiting block 12.

[0050] During use, align the limit block 12 with the notch 11, then lower the sealing cover 3 and cover it on the upper end of the annular box 1 to perform the fire extinguishing operation. After the fire extinguishing is completed, hold the handle 4 connected to the annular box 1 with one hand, hold the handle 5 connected to the sealing cover 3 with the other hand, and rotate the sealing cover 3. The limit block 12 rotates synchronously with the sealing cover 3. When the limit block 12 rotates to the side of the notch 11, stop rotating. At this time, the limit block 12 tightly presses the lower end and the upper end of the annular plate 10, and the lower end of the sealing cover 3 fits with the upper end of the annular box 1, thereby fixing the sealing cover 3 on the annular box 1. When removing the sealing cover 3, only need to rotate the limit block 12 to the position of the notch 11, and then lift the sealing cover 3 upward to remove it.

[0051] In order to improve the sealing effect between the lower end of the sealing cover 3 and the upper end of the annular box 1, in some embodiments of the present application, a sealing gasket (not shown in the figure) adapted to it is fixed at the lower end of the sealing cover 3, and the sealing gasket is made of high-temperature resistant rubber material.

[0052] In some embodiments of the present application, four internally threaded sleeves 13 distributed in a ring are fixed at the lower end of the annular box 1.

[0053] Two adjacent internally threaded sleeves 13 are engaged with a screw 14 adapted to it.

[0054] In this embodiment, when the top of the fermentation tank 15 is a flat structure, remove the screw 14, and the four internally threaded sleeves 13 horizontally support the annular box 1 on the top of the tank; when the top of the fermentation tank 15 is a curved surface structure, install the screw 14 on the internally threaded sleeve 13. When placing the annular box 1, let the two internally threaded sleeves 13 without the screw 14 be close to the center of the fermentation tank 15, and let the two screws 14 be close to the edge of the fermentation tank 15. Then rotate the screw 14 to adjust the position of the screw 14, so that the annular box 1 is horizontally placed on the top of the tank with a curved surface structure, so that the flame can be evenly distributed in the height direction. It can not only avoid the problem that miscellaneous bacteria are easily brought into the fermentation tank 15 due to uneven height of the flame, but also can stably support the annular box 1. During the inoculation process, the staff does not need to hold the handle 4 connected to the annular box 1 by hand.

[0055] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that; it is still possible to modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
