Description

Technical Field

[0001] The present invention relates to the technical field of sampling detection, and particularly relates to a sealed material fermentation device. Background Art

[0002] A material fermentation device usually consists of a closed container made of stainless steel or fiberglass, which is used to produce a large amount of microorganisms or their metabolites. During the fermentation process, it is usually necessary to extract a certain sample from the fermentation tank to observe the fermentation progress and control the fermentation conditions to ensure the quality of the final product. In the existing fermentation devices, when sampling, usually after determining the sampling position, a sampling tube is inserted into the fermentation tank to extract the sample of the fermentation liquid in the tank. In this way, through the sampling tube, the liquid at the sampling part is extracted by negative pressure. Then, during the extraction process, not only the fermentation liquid below the sampling tube is extracted into the tube, but also the surrounding fermentation liquid will flow into the sampling tube. After that, the fermentation liquid near the tube orifice will flow to supplement near the tube orifice, resulting in the sampling tube adsorbing this supplementary liquid into the sampling tube. As a result, the obtained fermentation liquid sample is not only the sample below the orifice of the sampling tube, but also doped with the fermentation liquid from other parts around, leading to the obtained sample not being able to represent the fermentation condition at a certain depth in the fermentation liquid, and ultimately causing deviation in the judgment of the fermentation process by the staff. Summary of the Invention

[0003] In order to overcome the above-mentioned drawbacks mentioned in the background art, the present invention provides a sealed material fermentation device.

[0004] The technical solution of the present invention is as follows: A sealed material fermentation device includes a fermentation tank.

The float is located inside the fermentation tank. An electric chuck is fixedly connected to the fermentation tank, and the electric chuck is slidably connected to the transmission rod.

[0010] As a further preferred solution, it further includes an isolation mechanism. The isolation mechanism is arranged in the fermentation tank. The isolation mechanism is used to isolate the gas in the sampling pipe. The isolation mechanism includes an isolation pipe. The isolation pipe is fixedly connected to the upper side of the sampling hole of the fermentation tank. The isolation pipe is rotatably connected with symmetrically distributed gears. The fermentation tank is fixedly connected with a first support block. The first support block is fixedly connected with symmetrically distributed third electric push rods.

The symmetrically distributed second baffles are fixedly connected with second racks. The symmetrically distributed first racks and the symmetrically distributed second racks are respectively meshed with the adjacent gears.

[0011] As a further preferred solution, it further includes a cleaning mechanism. The cleaning mechanism is arranged in the fermentation tank. The cleaning mechanism is used to clean the sampling pipe. The cleaning mechanism includes a connecting block. The connecting block is fixedly connected to the fermentation tank. The connecting block is fixedly connected with a cleaning shell. A circumferentially distributed water spraying pipe is arranged in the cleaning shell. A second support block is fixedly connected to the lower side in the cleaning shell. A circumferentially distributed cleaning pipe is fixedly connected to the upper side of the second support block. The cleaning pipe is located in the cleaning shell. The second support block is fixedly connected with a circumferentially distributed cylindrical shell. The cylindrical shell is fixedly connected with the adjacent cleaning pipe. The connecting block is provided with an adsorption component for adsorbing the fermented liquid on the inner wall of the sampling pipe.

[0012] As a further preferred solution, the inner wall of the cleaning shell is provided with uniformly distributed water spraying pipes. The water spraying pipes arranged at the lower part are denser than the water spraying pipes at the upper side. And the spray nozzles of the circumferentially distributed water spraying pipes at the lowermost side incline towards the middle of the cleaning shell.

[0013] As a further preferred solution, the adsorption component includes a second sliding rod. The second sliding rod is slidably connected to the connecting block.

The cylindrical pipe is fixedly connected with a second fixing block. The second fixing block is in limiting fit with the second limiting rod.

[0014] The beneficial effects of the present invention are as follows: By moving the sampling tube and the stopper downward and fixing the stopper after reaching the sampling depth, the sampling tube moves downward alone for sampling, avoiding sampling by suction, which may cause the liquid flow during the sampling operation to suck in the fermentation broth around the sampling tube mouth, resulting in a decrease in the representativeness of the sample.

[0015] The present invention blocks the filter holes on the stopper with a rectangular block, allowing the liquid passing through during the rotation of the stopper to flow out through the filter holes on the stopper, thereby reducing the liquid flow generated during the rotation of the stopper and preventing the flow of the fermentation broth from affecting the accuracy of the sample.

[0016] The present invention adjusts the distance that the disc extends below the liquid surface by moving the limit block downward, thereby adjusting the sampling height.

[0017] The present invention drives the first baffle to move by the telescopic end of the third electric push rod to isolate the sampling tube before and after sampling, avoiding the sampling tube from bringing a large amount of external air into the fermentation tank, resulting in a large amount of gas in the fermentation tank coming into contact and mixing with the outside air, and destroying the gas balance in the fermentation tank.

Detailed implementation manners

[0032] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0033] Embodiment 1: A sealed material fermentation device, as Figures 1 - 5As shown in the figure, it includes a fermentation tank 101. An inlet 102 and a sampling hole are arranged on the upper side of the fermentation tank 101. The inlet 102 is used to add the liquid to be fermented into the fermentation tank 101, and the sampling hole is used for the staff to put the sampling device into the fermentation tank 101 when sampling. An outlet 103 is arranged at the lower part of the fermentation tank 101, and the outlet 103 is used to discharge the liquid that has completed fermentation in the fermentation tank 101. A support frame 104 is fixedly connected to the upper side of the fermentation tank 101. A motor 105 with an output shaft fixedly connected to the support frame 104 and rotationally connected to the fermentation tank 101 is provided. The output shaft of the motor 105 is fixedly connected with stirring blades 106 symmetrically distributed in the fermentation tank 101, which are used to stir the fermentation liquid evenly after the fermentation liquid is put into the fermentation tank 101 to facilitate subsequent complete fermentation. A first electric push rod 107 is fixedly connected to the side of the support frame 104 away from the fermentation tank 101. The telescopic end of the first electric push rod 107 is fixedly connected with a first fixing block 108 slidably connected to the support frame 104. The first fixing block 108 is fixedly connected with a second electric push rod 109, and the telescopic end of the second electric push rod makes a downward direction. The telescopic end of the second electric push rod 109 is fixedly connected with a cylindrical tube 110. A first sliding rod 111 is slidably connected to the lower part inside the cylindrical tube 110. A disc 1111 is fixedly connected to the lower end of the first sliding rod 111. A sampling tube 112 is rotationally and slidably connected to the lower side of the first sliding rod 111. The sampling tube 112 is used to store the sampled fermentation liquid. The sampling tube 112 is slidably matched with the disc 1111, and the inner diameter of the sampling tube 112 is equal to the outer diameter of the disc 1111. When the disc 1111 moves upward, the fermentation liquid outside the sampling tube 112 can be adsorbed into the sampling tube 112 through negative pressure. The first sliding rod 111 is rotationally connected with a slider having a sliding connection with the disc 1111. A spring is connected between the slider and the disc 1111, and the spring is used to reset the position of the disc 1111. The slider is rotationally connected with symmetrically distributed stoppers 114. Symmetrically distributed and inclined chutes are opened on the lower side of the side wall of the sampling tube 112, and the inclination directions of the symmetrically distributed chutes are opposite. The symmetrically distributed stoppers 114 slide in the adjacent chutes on the sampling tube 112 respectively. The stoppers 114 are used to block the lower side surface of the sampling tube 112 after sampling to prevent the sampled liquid from leaking out. The stopper 114 is provided with a plugging mechanism for reducing the flow of the sampled liquid.

[0034] As Figures 6 - 8As shown in the figure, the plugging mechanism includes a rectangular block 201, which is slidably connected to the adjacent stop block 114. A compression spring 202 distributed axially is connected between the rectangular block 201 and the adjacent stop block 114. The compression spring 202 is used to reset the adjacent rectangular block 201. A cylindrical rod 203 is fixedly connected to the rectangular block 201. The cylindrical rod 203 and the sampling tube 112 are in extrusion fit, so that when the stop block 114 rotates, the cylindrical rod 203 contacts the sampling tube 112. The inner wall of the lower part of the sampling tube 112 extrudes the cylindrical rod 203 to move into the adjacent stop block 114. The support frame 104 is provided with a limiting mechanism for closing the sampling tube 112 after sampling.

[0035] As Figure 9 shown in the figure, the limiting mechanism includes a circular ring 301, which is fixedly connected to the cylindrical tube 110. The cylindrical tube 110 is rotationally connected to a limiting ring 302 in a limited way. A torsion spring 303 is connected between the limiting ring 302 and the circular ring 301. The torsion spring 303 is used to reset the limiting ring 302. A convex block is arranged at the upper end of the first sliding rod 111. An opening is arranged on one side of the limiting ring 302 close to the support frame 104. The size of the opening is the same as the width of the convex block at the upper end of the first sliding rod 111. And in the initial state, the opening is slightly misaligned with the convex block at the upper end of the first sliding rod 111. The cross-sectional side of the opening of the limiting ring 302 is set as an inclined surface facing downward. The inclined surface is in limiting cooperation with the convex block at the upper end of the first sliding rod 111. The opening of the limiting ring 302 can limit the downward movement of the convex block at the upper end of the first sliding rod 111. The limiting ring 302 is provided with a reset assembly for opening the sampling tube 112.

[0036] As Figure 9 shown in the figure, the reset assembly includes a first limiting rod 304, which is fixedly connected to the front side of the limiting ring 302. The first limiting rod 304 is used to rotate the limiting ring 302 to release the limitation of the convex block at the upper end of the first sliding rod 111. A reset block 305 is fixedly connected to the right end of the support frame 104. The reset block 305 is in limiting cooperation with the first limiting rod 304. When the first limiting rod 304 moves downward, the reset block 305 can squeeze the first limiting rod 304 to drive the limiting ring 302 to rotate.

[0037] When using the fermentation tank 101 for material fermentation, the staff adds the liquid material to be fermented into the fermentation tank 101 through the feed inlet 102, and starts the motor 105. The output shaft of the motor 105 drives the stirring blade 106 to rotate and stir the liquid material in the fermentation tank 101, so that the liquid material in the fermentation tank 101 is mixed evenly. After the liquid material is mixed evenly, the feed inlet 102 and the sampling hole are sealed and fermentation starts.

[0038] During the fermentation process, when it is necessary to observe the fermentation situation of the liquid in the fermenter 101, the staff opens the sampling hole and activates the first electric push rod 107. The telescopic end of the first electric push rod 107 pushes the first fixed block 108 to the upper side of the sampling hole of the fermenter 101. Then, the first electric push rod 107 is closed and the second electric push rod 109 is opened. The telescopic end of the second electric push rod 109 pushes the cylindrical tube 110 downward. The first sliding rod 111 moves downward under gravity following the cylindrical tube 110. The cylindrical tube 110 drives the sampling tube 112 downward. The sampling tube 112 drives the slider 113 downward. The slider 113 drives the stopper 114 downward. The first sliding rod 111 pushes the disc 1111 downward.

[0039] During the downward movement of the disc 1111, when the disc 1111 moves downward to the position where sampling is required, the staff fixes the convex block at the upper end of the first sliding rod 111. At this time, the disc 1111 is fixed and no longer moves downward. During this process, the telescopic end of the second electric push rod 109 continues to push the cylindrical tube 110 downward. The cylindrical tube 110 pushes the sampling tube 112 downward. The sampling tube 112 pushes the slider 113 downward. The slider 113 moves downward and compresses the spring between it and the disc 1111. The slider 113 pushes the stopper 114 downward. At this time, the stopper 114 and the sampling tube 112 move downward synchronously.

[0040] After the disc 1111 is fixed and no longer moves downward, the sampling tube 112 moves downward. At this time, the convex block on the side wall of the disc 1111 slides in the groove on the inner wall of the sampling tube 112. When the convex block on the side wall of the disc 1111 moves to the turning point of the groove on the inner wall of the sampling tube 112, the cylindrical tube 110 continues to push the sampling tube 112 downward. The groove on the inner wall of the sampling tube 112 is squeezed by the convex block on the side wall of the disc 1111 and rotates. The sampling tube 112 rotates and the chute on the lower side of its side wall squeezes the adjacent stopper 114. The stopper 114 is squeezed and rotates around its connection with the slider 113.

[0041] During the rotation of the above-mentioned stopper 114, the stopper 114 drives the adjacent rectangular block 201 and compression spring 202 to rotate. The rectangular block 201 drives the adjacent cylindrical rod 203 to rotate. Until the cylindrical rod 203 rotates and contacts and squeezes the sampling tube 112, the sampling tube 112 squeezes the rectangular block 201 and moves it into the stopper 114 and compresses the adjacent compression spring 202. The rectangular block 201 moves to block the filter hole opened on the adjacent stopper 114.

[0042] During the rotation of the above-mentioned stopper 114, the cylindrical tube 110 drives the ring 301 to move downward. The ring 301 drives the limit ring 302 to move downward through the torsion spring 303. The limit ring 302 drives the first limit rod 304 to move downward. When the limit ring 302 contacts the first slide rod 111, the first slide rod 111 squeezes the limit ring 302 to make it rotate. The limit ring 302 drives the torsion spring 303 to rotate and store energy. Until the limit ring 302 moves downward past the convex block at the upper end of the first slide rod 111, the first slide rod 111 releases the extrusion of the limit ring 302. The torsion spring 303 resets and drives the limit ring 302 to rotate and reset. At this time, the staff can release the convex block at the upper end of the first slide rod 111. The limit ring 302 limits the first slide rod 111 so that it does not move downward, and the disk 1111 at the lower end of the first slide rod 111 also no longer moves downward.

[0043] When the limit ring 302 limits the first slide rod 111, the symmetrically distributed stoppers 114 rotate to the same horizontal plane. At this time, the cylindrical rod 203 is completely squeezed into the adjacent stopper 114. The rectangular block 201 completely blocks the filter holes opened on the adjacent stoppers 114. At this time, the symmetrically distributed stoppers 114 jointly seal the lower side of the sampling tube 112, isolating the fermentation liquid between the disk 1111 and the stopper 114 from the fermentation liquid in the fermentation tank 101. When sampling, the sampling tube 112 and the stopper 114 move downward, and the filter holes on the stopper 114 are blocked by the rectangular block 201, so that the liquid passing through during the rotation of the stopper 114 can flow out through the filter holes on the stopper 114, thereby reducing the liquid flow generated during the rotation of the stopper 114 and preventing the flow of the fermentation liquid from affecting the accuracy of the sample.

[0044] After the fermentation liquid is isolated, the staff starts the second electric push rod 109 to retract the telescopic end. The telescopic end of the second electric push rod 109 drives the cylindrical tube 110 to move upward. The cylindrical tube 110 drives the ring 301 to move upward. The ring 301 drives the limit ring 302 to move upward through the torsion spring 303. The limit ring 302 drives the first slide rod 111 to move upward. The first slide rod 111 drives the disk 1111 to move upward. The disk 1111 pushes the slider 113 to move upward through the spring between it and the slider 113. The slider 113 drives the sampling tube 112 and the stopper 114 to move upward, moving the sampling tube 112 out of the fermentation tank 101, and completing the sampling of the fermentation liquid in the fermentation tank 101.

[0045] After the above sampling is completed, the staff activates the first electric push rod 107 to move the first limiting rod 304 above the reset block 305, and then activates the second electric push rod 109. The second electric push rod 109 pushes the cylindrical tube 110 downward. The cylindrical tube 110 drives the ring 301 downward. The ring 301 drives the limiting ring 302 downward through the torsion spring 303. The limiting ring 302 drives the first limiting rod 304 downward. After the reset block 305 contacts the first limiting rod 304, it squeezes and rotates the first limiting rod 304. The first limiting rod 304 drives the limiting ring 302 to rotate. The rotation of the limiting ring 302 releases the limitation on the first sliding rod 111. At this time, under the action of gravity, the first sliding rod 111 moves downward. The first sliding rod 111 pushes the disc 1111 downward. The downward movement of the disc 1111 resets the spring between it and the slider 113, and the slider 113 is pushed upward by the spring between it and the disc 1111. Therefore, the slider 113 does not move downward, and the stopper 114 is limited by the slider 113, so the stopper 114 does not move downward either. The slider 113 drives the sampling tube 112 not to move downward. Therefore, during the downward movement of the disc 1111, the groove on the side wall of the sampling tube 112 is squeezed and rotated by the convex block on the side wall of the disc 1111. The rotation of the sampling tube 112 squeezes the stopper 114 to rotate and reset through the chute opened at the lower part of its side wall. During the rotation of the stopper 114, the sampling tube 112 releases the extrusion on the cylindrical rod 203, and the compression spring 202 resets and pushes the adjacent rectangular block 201 to reset. The rectangular block 201 pushes the adjacent cylindrical rod 203 to reset.

[0046] [[ID=३]]During the rotation and reset process of the above-mentioned stopper 114, the rotation of the stopper 114 releases the blockage of the lower side of the sampling tube 112. At this time, the sampled sample is released from the sampling tube 112, and the staff picks up and observes the sample at the lower end of the sampling tube 112.

[0047] Example 2: On the basis of Example 1, as Figure 10 and Figure 11As shown in the figure, it further includes a detection mechanism. The detection mechanism is arranged on the fermentation tank 101 and is used to detect the liquid level height of the fermentation broth. The detection mechanism includes a transmission rod 401. The transmission rod 401 is slidably connected to the fermentation tank 101. A lead screw 402 is fixedly connected to the transmission rod 401. A limiting block 403 is slidably connected to the support frame 104. The limiting block 403 is in extrusion fit with the first slide rod 111. The limiting block 403 can limit the downward movement of the first slide rod 111 by blocking the movement of the upper convex block on the first slide rod 111. The limiting block 403 is threadedly connected to the lead screw 402. A knob 404 is fixedly connected to the lead screw 402 for manual adjustment of the height of the limiting block 403 by the staff. A float 405 is fixedly connected to the lower end of the transmission rod 401. The float 405 is located inside the fermentation tank 101 and is used to detect the liquid level height of the fermentation broth in the fermentation tank 101. The distance between the limiting block 403 and the float 405 is the distance between the upper convex block of the first slide rod 111 and the disc 1111, that is, when the upper convex block of the first slide rod 111 and the uppermost end of the limiting block 403 are at the same height, the disc 1111 just touches the liquid level of the fermentation broth. An electric chuck 406 is fixedly connected to the fermentation tank 101. The electric chuck 406 is used to fix the position of the transmission rod 401 during sampling, so that the float 405 no longer floats up and down. The electric chuck 406 is slidably connected to the transmission rod 401.

[0048] Before sampling, the float 405 moves up and down with the fermentation liquid level. The float 405 drives the transmission rod 401 to move up and down. The transmission rod 401 drives the lead screw 402 to move up and down. The lead screw 402 drives the limiting block 403 to slide inside the support frame 104. When sampling is required, the staff starts the electric chuck 406. The electric chuck 406 clamps and fixes the transmission rod 401 to fix the transmission rod 401. When sampling, the first slide rod 111 moves downward. When the upper convex block of the first slide rod 111 moves downward and contacts the limiting block 403, the lower side of the disc 1111 touches the liquid level of the fermentation broth. At this time, the limiting block 403 limits the first slide rod 111 to play a role in fixing the first slide rod 111.

[0049] Before sampling, the staff rotates the knob 404. The knob 404 drives the lead screw 402 to rotate. The lead screw 402 rotates to drive the limiting block 403 to move downward. At this time, when the first slide rod 111 moves downward and contacts the limiting block 403, the distance between the limiting block 403 and the top of the lead screw 402 is equal to the distance that the disc 1111 extends into the liquid surface. The position of the limiting block 403 can be adjusted by rotating the knob 404 to adjust the height of the sampling position of the sampling tube 112 from the liquid level during sampling.

[0050] Example 3: On the basis of Example 1, as Figure 12As shown in the figure, it further includes an isolation mechanism. The isolation mechanism is arranged in the fermentation tank 101 and is used to separate the gas in the sampling pipe 112 from the outside air, so as to ensure that the gas environment in the fermentation tank 101 will not be damaged during the sampling process. The isolation mechanism includes an isolation pipe 501. The isolation pipe 501 is fixedly connected to the upper side of the sampling hole of the fermentation tank 101. The isolation pipe 501 is rotatably connected with symmetrically distributed gears 502. The fermentation tank 101 is fixedly connected with a first support block 503. The first support block 503 is fixedly connected with symmetrically distributed third electric push rods 504. The telescopic ends of the third electric push rods 504 are fixedly connected with first baffles 505. The symmetrically distributed first baffles 505 are all slidably connected to the isolation pipe 501. The first baffles 505 are meshed with the adjacent gears 502. The first baffles 505 are fixedly connected with first racks 506. Symmetrically distributed second baffles 507 are slidably connected in the isolation pipe 501. The symmetrically distributed second baffles 507 are fixedly connected with second racks 508. The symmetrically distributed first racks 506 and the symmetrically distributed second racks 508 are respectively meshed with the adjacent gears 502. The first baffle 505 and the adjacent second baffle 507 cooperate together to block the opening on the isolation pipe 501, so that the inside of the isolation pipe 501 is relatively closed. Semi-circular openings are arranged on the opposite sides of the upper first baffle 505 and the upper second baffle 507. The radius of the opening is equal to the outer diameter of the cylindrical pipe 110, which is used to close the fermentation tank 101 while not affecting the cylindrical pipe 110 entering the fermentation tank 101 for sampling.

[0051] Before sampling the fermentation broth in the fermentation tank 101, start the upper third electric push rod 504. The third electric push rod 504 retracts its telescopic end. The telescopic end of the third electric push rod 504 drives the upper first baffle 505 to move. The first baffle 505 drives the adjacent first rack 506 to move. The movement of the first rack 506 drives the adjacent gear 502 to rotate. The rotation of the gear 502 drives the adjacent second rack 508 to move. The second rack 508 pushes the adjacent second baffle 507 to move. The upper first baffle 505 and the adjacent second baffle 507 move in opposite directions to open the upper opening of the isolation pipe 501.

[0052] After the opening on the upper side of the isolation pipe 501 is opened, the telescopic end of the second electric push rod 109 pushes the sampling pipe 112 downward through the cylindrical pipe 110 into the isolation pipe 501. At this time, turn off the second electric push rod 109 and start the upper third electric push rod 504. The telescopic end of the third electric push rod 504 extends to drive the upper first baffle 505 and the adjacent second baffle 507 to move towards the opposite side to close the upper opening of the isolation pipe 51. At this time, the gas in the fermentation tank 101 can be introduced into the isolation pipe 501 to make the inside of the isolation pipe 501 and the fermentation tank 101 in the same environment.

[0053] After being in the same environment as the fermentation tank 101 inside the isolation tube 501, start the third electric push rod 504 on the lower side. The third electric push rod 504 retracts its telescopic end. Repeat the above process to move the first baffle 505 and the adjacent second baffle 507 on the lower side in opposite directions, opening the opening on the lower side of the isolation tube 501. At this time, continue to start the second electric push rod 109. The telescopic end of the second electric push rod 109 pushes the sampling tube 112 downward through the cylindrical tube 110 to enter the fermentation tank 101 for sampling.

[0054] After completing the above sampling, the telescopic end of the second electric push rod 109 drives the sampling tube 112 upward through the cylindrical tube 110 to enter the isolation tube 501. Subsequently, turn off the second electric push rod 109, start the third electric push rod 504 on the lower side to close the opening on the lower side of the isolation tube 501. After closing, start the third electric push rod 504 on the upper side to open the opening on the upper side of the isolation tube 501, and start the second electric push rod 109 again to take out the sampled sample. The isolation tube 501 isolates the sampling tube 112 before and after sampling, preventing the sampling tube 112 from bringing a large amount of external air into the fermentation tank 101, resulting in a large amount of gas in the fermentation tank 101 coming into contact and mixing with the outside air during the sampling process due to the continuous opening of the sampling port of the fermentation tank 101, thereby destroying the gas balance in the fermentation tank 101.

[0055] Example 4: On the basis of Example 3, as Figure 13 shown, it further includes a cleaning mechanism. The cleaning mechanism is arranged on the fermentation tank 101 and is used to clean the fermentation liquid adhering to the outer side and inner wall of the sampling tube 112. The cleaning mechanism includes a connecting block 601. The connecting block 601 is fixedly connected to the fermentation tank 101. The connecting block 601 is fixedly connected with a cleaning shell 606. The cleaning shell 606 prevents the splashing of the cleaning liquid during the cleaning process. The inner wall of the cleaning shell 606 is provided with spray pipes evenly distributed. The spray pipes are used to spray cleaning liquid and water onto the sampling tube 112. The spray pipes arranged at the lower part are denser than the spray pipes on the upper side to focus on cleaning parts with smaller parts such as the baffle 114 part on the lower side of the sampling tube 112. Moreover, the spray nozzles of the circumferentially distributed spray pipes at the lowermost side are inclined towards the middle of the cleaning shell 606, so that the sprayed cleaning liquid has a longer contact time with the sampler 112. A second support block 607 is fixedly connected to the lower side inside the cleaning shell 606. A circumferentially distributed cleaning pipe 608 is fixedly connected to the upper side of the second support block 607. The cleaning tank 608 is used to spray cleaning liquid onto the inner wall of the sampler 112 for cleaning. The cleaning pipe 608 is located inside the cleaning shell 606. The second support block 607 is fixedly connected with a circumferentially distributed cylindrical shell 609. The cylindrical shell 609 is provided with holes for sucking and extracting the residual fermentation liquid in the sampler 112 by negative pressure before cleaning, thereby reducing the difficulty of subsequent flushing. The cylindrical shell 609 is fixedly connected to the adjacent cleaning pipe 608. The connecting block 601 is provided with an adsorption component for adsorbing the fermentation liquid on the inner wall of the sampling tube 112.

[0056] like Figure 13 As shown, the adsorption component includes a second slide rod 602, which is slidably connected to the connecting block 601, and a first spring 603 is connected between the second slide rod 602 and the connecting block 601. The first spring 603 is released after storing force, thereby providing power for negative pressure adsorption, and the second slide rod 602 is slidably connected to a second limiting rod 604, and a second spring 605 is connected between the second limiting rod 604 and the second slide rod 602. The second spring 605 is used to reset the second limiting rod 604, and a cavity is provided in the second support block 607. The cavity in the second support block 607 is connected to the connecting block 601, and the circumferentially distributed cylindrical shells 609 are all connected to the cavity in the second support block 607. The second clamping block 610 is fixed to the upper side of the cleaning shell 606 for releasing the pressure of the first spring 603, thereby generating a negative pressure in the connecting block 601, and adsorbing the fermentation liquid remaining on the inner wall of the sampling tube 112 through the circumferentially distributed cylindrical shell 609. The second clamping block 610 is squeezed and matched with the second limiting rod 604, and the second clamping block 610 can push the second limiting rod 604 to move to the left. The lower part of the cylindrical tube 110 is fixed with a second fixing block 611, and the second fixing block 611 is limitedly matched with the second limiting rod 604, so that when the cylindrical tube 110 moves downward, the cylindrical tube 110 can push the second limiting rod 604 to move downward through the second fixing block 611.

[0057] After completing the sample observation, start the second electric push rod 109, and the second electric push rod 109 pushes the sampling tube 112 downward through the cylindrical tube 110, and the cylindrical tube 110 drives the second fixed block 611 to move downward until the second fixed block 611 contacts the second limiting rod 604, and the second fixed block 611 squeezes the second limiting rod 604 to move downward, and the second limiting rod 604 drives the second slide bar 602 to move downward, and the second slide bar 602 moves downward to compress the first spring 603, and the gas between the connecting block 601 and the lower side of the second slide bar 602 is discharged through the lower side opening and the cleaning tube 608.

[0058] During the downward movement of the sampling tube 112, when the sampling tube 112 completely enters the cleaning shell 606, the second limiting rod 604 contacts the block 610, and the block 610 squeezes the second limiting rod 604 to move in the direction close to the fermentation tank 101. The second limiting rod 604 moves and does not contact the second fixed block 611, and compresses the second spring 605. After the second limiting rod 604 does not contact the second fixed block 611, the first spring 603 resets and pushes the second sliding rod 602 to move upward. The second sliding rod 602 pushes the second limiting rod 604 to move upward. After the second limiting rod 604 passes the second fixed block 611 upward, the second spring 605 resets and pushes the second limiting rod 604 to reset.

[0059] During the process of returning the first spring 603, the upper part of the cleaning tube 608 has entered the sampling tube 112, and negative pressure is formed in the connecting block 601. Air is adsorbed inward through the small holes opened on the lower side of the connecting block 601 and the cleaning tube 608. The cleaning tube 608 adsorbs the residual fermentation liquid attached to the inner wall of the sampling tube 112, and adsorbs it into the connecting block 601 through the cavity in the second support block 607 and discharges it. Thereafter, the inner and outer walls of the sampling tube 112 are rinsed and cleaned through the circumferentially distributed water spray pipes on the inner wall of the cleaning shell 606 and the circumferentially distributed cleaning tubes 608.
