Description

Technical Field

[0001] This utility model relates to the field of microbial fermentation sampling technology, and in particular to a microbial fermentation device with a closed sampling function. Background Technology

[0002] Microbial fermentation is a core technology that utilizes the metabolic activities of microorganisms to produce target products (such as enzymes, antibiotics, amino acids, biofuels, etc.). It is widely used in the fields of medicine, food, chemical industry and bioenergy. With the advancement of biotechnology, the sampling process is a key step in monitoring the fermentation status, reducing the time that the collected samples are in contact with air.

[0003] Quickly attach the sample collection bottle to the connecting pipe on one side of the fermenter. After securing the sample bottle, turn on the switch connected to the fermenter. The fermentation material will flow into the sample bottle through the pipe. Finally, send the extracted sample for testing.

[0004] Existing microbial fermentation devices require multiple rotations of the switch to sample the fermenting microorganisms, which is a cumbersome process that results in longer sampling times and extended exposure of the microorganisms to air, ultimately leading to inaccurate sample test results. Therefore, a microbial fermentation device with a closed sampling function is proposed. Utility Model Content

[0006] To address the problems existing in the prior art, this utility model provides a microbial fermentation device with a closed sampling function.

[0010] As a preferred embodiment of the microbial fermentation device with closed sampling function described in this utility model, the locking mechanism includes a hollow ring, with multiple locking blocks arranged circumferentially inside the hollow ring, a second spring installed on one side of each locking block, a collection bottle disposed inside the hollow ring, and a push ring movably installed inside the hollow ring.

[0016] (III) Beneficial Effects

[0017] This invention provides a microbial fermentation device with a closed sampling function. It has the following beneficial effects:

[0018] 1. Through the action of the sampling mechanism, the channel of the first housing can be opened without multiple rotations of the shaft. Manually pulling the lever outward causes the limiting ring and the semi-circular retaining tooth to move outward simultaneously. The semi-circular retaining tooth disengages from the outer gear ring. At this time, manually rotating the shaft causes the hemisphere to change from vertical to horizontal, opening the channel of the first housing. After the shaft stops rotating, the tension applied to the lever is released. Under the action of the first spring, the limiting ring is pushed in the opposite direction, thereby pushing the semi-circular retaining tooth into the outer gear ring, restricting the rotation of the outer gear ring. This has the function of quickly opening the channel of the first housing, increasing the speed at which the sample is discharged from the container, reducing the contact time between the sample and air, and improving the accuracy of sample detection.

[0019] 2. Through the action of the snap-fit ​​mechanism, the collection bottle can be quickly installed at the bottom of the hollow ring. Push the bottle opening upwards from the bottom of the hollow ring until all the protrusions at the bottle opening are locked by the snap-fit ​​blocks, completing the installation of the collection bottle. After sampling is completed, push the push ring upwards. The push ring moves the snap-fit ​​blocks into the corresponding grooves in the hollow ring, allowing multiple snap-fit ​​blocks to release their restriction on the collection bottle. The collected bottle can then be removed. This facilitates sampling, reduces the contact between the sample and air, and improves the accuracy of the test results. Attached Figure Description

[0028] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0029] Example 1

[0030] Reference Figure 1 , Figure 2 and Figure 3 This is the first embodiment of the present invention. This embodiment provides a microbial fermentation device with a closed sampling function, including a tank 1, a sampling mechanism 2 on one side of the tank 1, and a locking mechanism 3 on one side of the sampling mechanism 2.

[0031] The layout mechanism 2 includes a first housing 201 disposed on one side of the tank body 1. A rotating shaft 204 is movably installed inside the first housing 201. A hemisphere 205 is fixedly connected to the outer surface of the inner cavity of the rotating shaft 204. An external gear ring 211 is fixedly installed on the top outer surface of the rotating shaft 204. A semi-circular retaining tooth 210 is provided on one side of the external gear ring 211.

[0032] Specifically, by pulling the semi-circular retaining tooth 210 outward from inside the outer gear ring 211 to release it from its restriction, and manually rotating the rotating shaft 204, the rotating shaft 204 drives the outer gear ring 211 and the hemisphere 205 to rotate simultaneously. By rotating the vertical hemisphere 205 to the horizontal position, the channel of the first housing 201 can be quickly opened, thereby improving the efficiency of sample collection.

[0033] Specifically, the rotating shaft 204 is rotatably connected inside the first housing 201, the outer gear ring 211 is adapted to the semi-circular retaining tooth 210, and the hemisphere 205 is rotatably connected in the inner cavity of the first housing 201. Under the action of the hemisphere 205, when the hemisphere 205 rotates around the rotating shaft 204 in the inner cavity of the first housing 201, it can control the opening and closing of the channel of the first housing 201.

[0034] Specifically, the top of the first housing 201 is symmetrically provided with side plates 206, and a pull rod 207 is slidably connected inside the side plates 206. A limit ring 209 is fixedly installed on the outer surface of the pull rod 207. A first spring 208 is provided on one side of the limit ring 209. A semi-circular locking tooth 210 is fixedly installed on one side of the pull rod 207. When the pull rod 207 is pulled outward, it can drive the limit ring 209 and the semi-circular locking tooth 210 to move outward at the same time, so that the semi-circular locking tooth 210 is released from the restriction of the outer gear ring 211. When the pulling force on the pull rod 207 is released, under the action of the first spring 208, the limit ring 209 is pushed in the opposite direction, so that the semi-circular locking tooth 210 is locked on the outer gear ring 211, thus restricting the rotation of the rotating shaft 204.

[0035] Specifically, the limiting ring 209 and the first spring 208 are located on opposite sides of the two side plates 206. The first spring 208 is located outside the pull rod 207. The guide pipe 203 and the receiving pipe 202 are fixedly connected to both sides of the first housing 201, and the guide pipe 203 is connected to the tank body 1.

[0036] Furthermore, manually pull the lever 207 outward. The lever 207 drives the limiting ring 209 and the semi-circular locking tooth 210 to move outward simultaneously. The semi-circular locking tooth 210 disengages from the outer gear ring 211. At this time, manually rotate the rotating shaft 204. The rotating shaft 204 drives the hemisphere 205 to change from vertical to horizontal, opening the channel of the first housing 201. After the rotating shaft 204 stops rotating, remove the pulling force applied to the lever 207. Under the action of the first spring 208, push the limiting ring 209 in the opposite direction, thereby pushing the semi-circular locking tooth 210 into the outer gear ring 211, thus restricting the rotation of the outer gear ring 211.

[0037] Example 2

[0038] Reference Figure 4 , Figure 5 and Figure 6 This is the second embodiment of the present invention. This embodiment is based on the previous embodiment. The locking mechanism 3 includes a hollow ring 303. Multiple locking blocks 307 are arranged circumferentially inside the hollow ring 303. A second spring 306 is installed on one side of the locking block 307. A collection bottle 305 is provided in the inner cavity of the hollow ring 303. A push ring 304 is movably installed in the inner cavity of the hollow ring 303.

[0039] Specifically, push the neck of the collection bottle 305 upwards from the bottom of the hollow ring 303, and lock the neck of the collection bottle 305 onto the locking block 307. This makes it easier to install the collection bottle 305 in the inner cavity of the hollow ring 303, reducing the contact time between the sample and air.

[0040] Specifically, the inner surface of the hollow ring 303 is circumferentially provided with grooves that are adapted to the locking blocks 307. The locking blocks 307 are slidably connected inside the grooves and are movably locked at the mouth of the collection bottle 305. Under the action of multiple second springs 306, the corresponding locking blocks 307 are pushed towards the center of the hollow ring 303 at the same time. Under the action of multiple locking blocks 307, the collection bottle 305 is stabilized in the hollow ring 303.

[0041] Specifically, multiple T-shaped sliders are circumferentially distributed on the outer surface of the push ring 304. The T-shaped sliders are slidably connected inside the second housing 301. The second housing 301 is adapted to multiple locking blocks 307. A discharge pipe 302 is fixedly installed on the top of the hollow ring 303. The second housing 301 is fixedly connected to the top of the discharge pipe 302. The second housing 301 is fixedly installed on one side of the receiving pipe 202.

[0042] Next, push the bottle opening of the collection bottle 305 upwards from the bottom of the hollow ring 303 until all the protrusions at the bottle opening of the collection bottle 305 are locked by the locking blocks 307, thus completing the installation of the collection bottle 305. After sampling is completed, push the push ring 304 upwards. The push ring 304 moves the locking blocks 307 into the corresponding grooves in the hollow ring 303, so that the multiple locking blocks 307 are released from the restriction of the collection bottle 305. The collection bottle 305 after sampling can then be removed and sent for testing.

[0043] Working principle: The tank 1 is connected to an external power supply and controller via a wiring harness. The tank 1 has an existing structure and is the same as those disclosed in the prior art. When sampling is required, the mouth of the collection bottle 305 is pushed upward from the bottom of the hollow ring 303. Once the protrusions at the mouth of the collection bottle 305 are all locked by the locking blocks 307, the collection bottle 305 is fixed. The pull rod 207 is manually pulled outward. The pull rod 207 drives the limiting ring 209 and the semi-circular locking teeth 210 to move outward simultaneously. The semi-circular locking teeth 210 disengage from the outer toothed ring 211. At this time, the rotating shaft 204 is manually rotated. The rotating shaft 204 drives the hemisphere 205 to change from vertical to horizontal, opening the channel of the first shell 201. The sample flows from the tank 1 sequentially into the guide tube 203, the first shell 201, the receiving tube 202, the second shell 301, and the discharge tube 302, and finally flows into the collection bottle 305. In step 5, after the rotating shaft 204 stops rotating, the tension applied to the pull rod 207 is released. Under the action of the first spring 208, the limiting ring 209 is pushed in the opposite direction, thereby pushing the semi-circular locking tooth 210 into the outer gear ring 211 and restricting the rotation of the outer gear ring 211. After the collection bottle 305 has been collected, the pull rod 207 is pulled outward again, and the principle is the same as above, so that the semi-circular locking tooth 210 is disengaged from the outer gear ring 211. The rotating shaft 204 is rotated in the opposite direction, and the channel of the outer gear ring 211 is closed through the hemisphere 205. Then, the push ring 304 is manually pushed upward. The push ring 304 moves the locking blocks 307 into the corresponding groove cavity of the hollow ring 303, so that the multiple locking blocks 307 are released from the restriction of the collection bottle 305. The collection bottle 305 after sampling can be taken out downward from the cavity of the hollow ring 303.
