Description

Technical Field

[0001] This utility model relates to the field of biological inoculation technology, and in particular to an inoculation tool for a 50L bacitracin zinc fermenter. Background Technology

[0002] In the production of bacitracin zinc, laboratory fermentation begins with the cultivation of microorganisms in test tubes. Once the microorganisms are successfully cultivated, they need to be transferred to a 50L fermenter for scale-up cultivation until the conditions for industrial production are met. All of these inoculation steps must be carried out under flame protection to ensure aseptic operation and prevent contamination of the fermentation environment by other microorganisms.

[0003] The existing patent application, with publication number CN 205295336 U and publication date June 8, 2016, is titled "A Flame Inoculation Device for a Fermentation Tank." This patent includes a ring-shaped alcohol lamp and a sealing cap. The inoculation device also includes a flame inoculation port, which is fixedly connected to the fermentation tank inlet. The ring-shaped alcohol lamp is fitted over the flame inoculation port, with a gap between the inner ring wall of the ring-shaped alcohol lamp and the outer wall of the flame inoculation port. The sealing cap covers the upper part of the flame inoculation port and provides a sealed connection. Compared with existing technologies, this invention has advantages such as simple structure, convenient operation, good sealing effect, and low risk of bacterial contamination.

[0004] In the aforementioned prior art, the ring-shaped alcohol lamp has a fixed height. If the wind is strong, it will affect the stability of the flame, thereby affecting the aseptic state during the inoculation process and may even lead to safety hazards. At the same time, the cleaning and disinfection process of the inoculation tools is cumbersome, especially in small structures, where it is difficult to quickly and thoroughly remove alcohol swabs and other residues. Utility Model Content

[0005] The purpose of this invention is to provide an inoculation tool for a 50L bacitracin zinc fermenter to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an inoculation tool for a 50L bacitracin zinc fermenter, comprising an inoculation ring, an adjusting base rotatably mounted on the bottom of the inoculation ring, an alcohol swab trough with a top opening formed between the adjusting base and the inoculation ring, a windproof component vertically slidingly mounted inside the alcohol swab trough, symmetrically mounted abutting rods on the top of the adjusting base, the abutting rods engaging with the windproof component, and an arc-shaped track fixedly connected to the inner wall of the inoculation ring for the abutting rods to move along, with an outlet at one end of the arc-shaped track.

[0007] Preferably, a bracket is installed on one side of the inoculation loop, and a handle is fixedly connected to the end of the bracket.

[0008] Preferably, the inoculation loop includes an outer ring and an inner ring located at the center of the outer ring, and a plurality of connecting rods are fixedly connected between the outer ring and the inner ring.

[0009] Preferably, the arc-shaped track is fixed to the inner wall of the outer ring, and the top of the abutment rod is attached to the arc-shaped track.

[0010] Preferably, the windproof component includes an annular windproof cover, the outer wall of which is fixedly connected to a sliding rod, and the inner wall of the inoculation ring is vertically provided with a limiting groove that matches the sliding rod.

[0011] Preferably, guide rods are fixedly connected to both sides of the outer wall of the annular windproof cover, and the top surface of the abutting rod abuts against the bottom of the guide rod.

[0012] Preferably, the outer wall of the adjusting base is provided with a ring of anti-slip protrusions, which protrude from the outside of the inoculation ring.

[0013] Preferably, a barrier ring is installed inside the alcohol swab tank, the outer wall of the barrier ring is fitted with the inner wall of the annular windproof cover, and the bottom of the barrier ring is provided with a slot that matches each connecting rod.

[0014] This invention provides an inoculation tool for a 50L bacitracin zinc fermenter. It has the following beneficial effects:

[0015] This bacitracin zinc 50L fermenter inoculation tool effectively reduces the risk of contamination during inoculation by burning alcohol cotton in an alcohol cotton tank, ensuring a sterile environment for fermentation. The design of the adjustable base and arc-shaped track makes the inoculation operation more flexible. The adjustable base can be turned to quickly raise the windproof component, enhancing the stability of the flame. At the same time, after the flame is extinguished after inoculation, the adjustable base can be turned in the opposite direction to move the abutment rod out of the arc-shaped track, allowing the entire adjustable base to be removed directly, reducing the difficulty of cleaning and maintenance, and making it easy to remove the alcohol cotton.

[0022] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0023] Reference Figure 1-4 An inoculation tool for a 50L bacitracin zinc fermenter includes an inoculation ring 1, an adjusting base 2 rotatably mounted on the bottom of the inoculation ring 1, an alcohol swab trough 3 with a top opening formed between the adjusting base 2 and the inoculation ring 1 for placing alcohol-soaked cotton balls, a windproof component 4 vertically sliding within the alcohol swab trough 3, and symmetrically mounted abutting rods 5 on the top of the adjusting base 2, which abut against the windproof component 4. An arc-shaped track 6 for the abutting rods 5 to move is fixedly connected to the inner wall of the inoculation ring 1, and one end of the arc-shaped track 6 has an outlet 61. This novel 50L fermenter inoculation tool is adjusted by rotating the adjusting base. 2. By sliding the abutment rod 5 on the arc-shaped track 6, the windproof component 4 is pushed to adjust the height of the windproof component 4 in the alcohol swab tank 3, thereby controlling the exposure degree of the alcohol swab. This ensures the disinfection effect during the inoculation process and effectively prevents external air from interfering with alcohol evaporation. When it is necessary to replace the alcohol swab, simply rotate the adjusting base 2 to a specific position so that the abutment rod 5 disengages from the outlet 61 of the arc-shaped track 6. The entire adjusting base 2 can then quickly separate from the inoculation ring 1, making the bottom of the alcohol swab tank 3 open, which is convenient for operators to remove the swab for cleaning and maintenance.

[0024] In this invention, a bracket 7 is installed on one side of the inoculation ring 1, and a handle 8 is fixedly connected to the end of the bracket 7. During the inoculation process, the operator can stably control the entire inoculation tool by holding the handle 8. The design of the bracket 7 and the handle 8 not only provides a stable grip point but also makes the operation more convenient and comfortable. The entire inoculation process not only ensures the requirements of aseptic operation but also improves work efficiency and the operator's user experience.

[0025] In this invention, the inoculation ring 1 includes an outer ring 11 and an inner ring 12 located at the center of the outer ring 11. Several connecting rods 13 are fixedly connected between the outer ring 11 and the inner ring 12. The connecting rods 13 are evenly distributed between the outer ring 11 and the inner ring 12, which not only play a supporting and reinforcing role, but also make the overall structure of the inoculation ring 1 more stable and able to withstand greater operating force. This ensures that the inoculation ring 1 can be evenly stressed when inserted into the fermentation tank, avoiding damage caused by excessive local stress. At the same time, it can also prevent the alcohol cotton from falling off during the burning process with the cooperation of the outer ring 11 and the inner ring 12.

[0026] In this invention, the arc-shaped track 6 is fixed to the inner wall of the outer ring 11, and the top of the abutment rod 5 is hung on the arc-shaped track 6. The rotation of the adjusting base 2 will cause the abutment rod 5 to slide on the arc-shaped track 6. Since the top of the abutment rod 5 is hung on the arc-shaped track 6, its sliding process is stable and controllable. By adjusting the position of the abutment rod 5, it can push the windproof component 4, thereby adjusting the height of the windproof component 4 in the alcohol cotton tank 3, thereby controlling the exposure degree of the alcohol cotton ball and avoiding excessive wind force from affecting the combustion effect of the alcohol cotton.

[0027] In this invention, the windproof component 4 includes an annular windproof cover 41. A sliding rod 42 is fixedly connected to the outer wall of the annular windproof cover 41. A limiting groove 14 matching the sliding rod 42 is vertically opened on the inner wall of the inoculation ring 1. By adjusting the rotation of the base 2, the abutment rod 5 can slide on the arc track 6. When the abutment rod 5 abuts against the annular windproof cover 41, since the annular windproof cover 41 can only move in the vertical direction, it will not deflect to the left or right, thereby realizing the adjustment of the height of the annular windproof cover 41 in the alcohol cotton tank 3, thus quickly protecting the flame when the alcohol cotton is burning.

[0028] In this utility model, guide rods 43 are fixedly connected to both sides of the outer wall of the annular windproof cover 41. The top surface of the abutting rod 5 abuts against the bottom of the guide rod 43. After the abutting rod 5 abuts against the guide rod 43, turning the adjusting base 2 in one direction will force the annular windproof cover 41 to rise. When the adjusting base 2 is turned in the other direction, the annular windproof cover 41 will fall. After the adjusting base 2 is further rotated, the abutting rod 5 will move out from the outlet 61 of the arc-shaped guide rail, thereby facilitating the quick separation of the adjusting base 2 and making it easier to clean the alcohol swab tank 3.

[0029] In this utility model, the outer wall of the adjusting base 2 is provided with a ring of anti-slip protrusions 21. The anti-slip protrusions 21 protrude from the outer side of the inoculation ring 1. The anti-slip protrusions 21 increase the friction and prevent the adjusting base 2 from being misaligned when it is turned.

[0030] In this utility model, an isolation ring 9 is installed inside the alcohol cotton tank 3. The outer wall of the isolation ring 9 is fitted with the inner wall of the annular windproof cover 41, and the bottom of the isolation ring 9 is provided with a slot 91 that matches each connecting rod 13. The isolation ring 9 can still block the alcohol cotton after the entire windproof component 4 is raised, so that the alcohol cotton and the abutment rod 5 are separated, avoiding the problem of the adjustment base 2 not rotating smoothly.

[0031] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
