Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] Embodiment 1 See also Figures 1 to 9 The present invention provides a technical solution: a real-time detection device for vinegar fermentation, comprising: a fermentation tank 11, a stirring motor 12 is arranged on the upper side of the fermentation tank 11, and a stirring member 13 is arranged at the output end of the stirring motor 12, The invention also includes: a sampling assembly 2, which is arranged in the fermentation tank 11 and is used to sample the vinegar in the fermentation tank 11; The adjustment component 3 is arranged on the outside of the fermentation tank 11 and is used for detecting and adjusting the vinegar after sampling.

[0019] A feed pipe and a discharge pipe are respectively arranged on the upper and lower sides of the fermentation tank 11. The feed pipe is used for feeding vinegar raw materials, and the discharge pipe is used for discharging vinegar after fermentation. The stirring motor 12 drives the stirring member 13 to rotate, so that the vinegar in the fermentation tank 11 can be stirred and mixed evenly during the fermentation process to improve the fermentation effect. Through the sampling component 2, the vinegar in the upper layer, the middle layer and the lower layer of the fermentation tank 11 can be sampled at set intervals to sample and detect the vinegar in the fermentation tank 11, and the sampling position of the vinegar can be automatically adjusted as the liquid level of the vinegar in the fermentation tank 11 changes, so as to increase the accuracy of sampling, thereby improving the representativeness of the detection result, so as to facilitate the sampling and detection of vinegar at different depths. Through the adjustment component 3, the interval time of subsequent vinegar sampling can be adjusted according to the detection after the vinegar sampling, so as to ensure that the fermentation of the vinegar meets the requirements.

[0020] Embodiment 2 The sampling assembly 2 includes a first sampling piece 21 fixed at the bottom end of the inner side of the fermentation tank 11, and two second sampling pieces 22 are slidably arranged in the fermentation tank 11. The two second sampling pieces 22 are above the first sampling piece 21 and are arranged up and down. The upper and lower second sampling pieces 22 respectively sample the upper and middle vinegar, and the first sampling piece 21 samples the lower vinegar. The inner wall of the fermentation tank 11 is provided with a limiting groove 23 adapted to the second sampling piece 22. The two second sampling pieces 22 slide up and down along the limiting groove 23. The limiting groove 23 is set to a trapezoidal shape, which can guide and limit the up and down movement of the second sampling piece 22.

[0021] The upper sides of the first sampling member 21 and the second sampling member 22 are both fixedly connected with a sampling tube 24, on which a first electromagnetic valve is installed, and is arranged on the inner side of the first sampling member 21 or the second sampling member 22 to prevent vinegar from corroding the first electromagnetic valve. The lower sides of the first sampling member 21 and the second sampling member 22 are both fixedly connected with a liquid outlet pipe 25, on which a second electromagnetic valve is installed, and the outer side of the second electromagnetic valve is sleeved with a first sampling member 21 or the second sampling member 22 and the liquid outlet pipe 25. 5 is fixed with a protective shell (not shown in the figure) to protect the second solenoid valve. The liquid outlet pipe 25 is set as a hose to adapt to the up and down movement of the two second sampling members 22. The bottom of the first sampling member 21 and the second sampling member 22 is provided with a slope toward the liquid outlet pipe 25. One end of the liquid outlet pipe 25 is fixed with an input end of a delivery pump 27, and the output end of the delivery pump 27 is fixed with a connecting pipe 28. A mounting seat 26 is fixed on one side of the fermentation tank 11, and the delivery pump 27 is fixed on the upper side of the mounting seat 26. After the set time is reached, the controller will control the first solenoid valve on the sampling tube 24 to open, so that the vinegar in the upper layer and the middle layer in the fermentation tank 11 enter the upper and lower second sampling parts 22 through the sampling tube 24 respectively, and the lower layer vinegar enters the first sampling part 21 through the sampling tube 24, so as to sample the vinegar in the upper layer, the middle layer and the lower layer respectively. Then, the first solenoid valve on the sampling tube 24 is controlled to close, and the second solenoid valve on the liquid outlet pipe 25 is controlled to open, and the delivery pump 27 is operated to extract the vinegar collected in the first sampling part 21 and the two second sampling parts 22 through the liquid outlet pipe 25 respectively, and output them through the connecting pipe 28, so that the vinegar in the upper layer, the middle layer and the lower layer can be detected respectively.

[0022] A float 215 is fixedly arranged on the upper side of the upper second sampling member 22. The float 215 can drive the upper second sampling member 22 to move up and down as the liquid level of the vinegar in the fermentation tank 11 changes, so that the upper second sampling member 22 can always sample the upper vinegar. A first gear condition 29 is fixedly arranged on one side of the upper second sampling member 22, and a second gear condition 210 is fixedly arranged on one side of the lower second sampling member 22. A first gear 211 is meshedly connected to one side of the first gear condition 29, and a second gear 212 is meshedly connected to one side of the second gear condition 210. The diameter of the first gear 211 is twice that of the second gear 212. A support rod 213 fixed to the inner wall of the fermentation tank 11 is rotatably arranged in the middle of the first gear 211 and the second gear 212. A sleeve 214 sleeved on the outside of the support rod 213 is fixedly arranged between the first gear 211 and the second gear 212. When the vinegar liquid level in the fermentation tank 11 is different or changes, for example, when the vinegar liquid level is high, the float 215 drives the upper second sampling member 22 to move upward through the buoyancy of the float 215, so that the first gear 29 drives the first gear 211 to rotate, and the sleeve 214 allows the second gear 212 to rotate the same number of circles or amplitude as the first gear 211, so that the second gear 212 drives the second gear 210 to move upward by half the upward distance of the first gear 29, so that After the upper second sampling member 22 moves up with the float 215, the lower second sampling member 22 moves up half the distance, so that the upper and lower second sampling members 22 can always sample the upper and middle layers of vinegar respectively. Conversely, when the vinegar liquid level is low, the lower second sampling member 22 can be moved down half the distance of the upper second sampling member 22. Thus, through the sampling assembly 2, it is convenient to sample and detect vinegar at different depths, and the sampling position can be automatically adjusted according to the different vinegar liquid levels.

When the electromagnetic block 32 is energized, it can repel the magnetic block 35. A connecting rod 36 that movably penetrates the mounting tube 31 is fixed on the other side of the slider 33. A first spring 37 that is sleeved on the outside of the connecting rod 36 is fixed between the slider 33 and the inner wall of the mounting tube 31.

[0024] Two connecting members 38 are fixedly provided on the outer side of the connecting rod 36, and a rotating plate 39 is movably provided between each two connecting members 38. Through grooves 310 are provided on both sides of the rotating plate 39, and the connecting members 38 are movably provided along the through grooves 310. An L-shaped rod 311 is rotatably provided in the middle of the rotating plate 39, and a sliding rod 312 fixed to the mounting seat 26 is slidably provided on one side of the L-shaped rod 311. The movement of the connecting member 38 driven by the connecting rod 36 can make the rotating plate 39 move or rotate; a first mounting frame 316 and a second mounting frame 317 are respectively fixedly provided on the upper side of the mounting seat 26, a first motor 318 is fixedly provided on the upper side of the first mounting frame 316, and a second motor 319 is fixedly provided on the upper side of the second mounting frame 317, a rotating disk 320 is fixedly provided on the output shaft of the first motor 318, and a pressing plate 325 is fixedly provided on the output shaft of the second motor 319, and the pressing plate 325 cooperates with the moving block 326.

[0025] A mounting block 321 fixed to the mounting seat 26 is provided on the lower side of the turntable 320, and the mounting block 321 does not hinder the rotation of the turntable 320. A gear switch 322 and a second switch 323 are respectively installed on both sides of the mounting block 321, and the second switch 323 is electrically connected to the first motor 318. A connecting block 324 is fixed on one side of the turntable 320 located on the mounting block 321, so that during the rotation of the turntable 320, the connecting block 324 will not touch the pressing plate 325. Mounting plates 314 are symmetrically fixed on both sides of the L-shaped rod 311, and the first switch 315 electrically connected to the first motor 318 is installed on the upper side of the mounting plate 314. A pressing block 313 is fixed on the side of the rotating plate 39 away from the sliding rod 312, and a circular arc chamfer is provided on the inner lower end of the pressing block 313 to facilitate the pressing of the pressing block 313 on the first switch 315.

[0026] Two moving blocks 326 are slidably provided on one side of the turntable 320, and the side of the moving block 326 away from the third switch 327 is set as an inclined surface, and the turntable 320 is provided with sliding grooves 330 on both sides of the moving block 326, and the sliding grooves 330 are adapted to the moving block 326. The moving block 326 slides along the sliding grooves 330, which can guide the movement of the moving block 326. A second spring 328 fixed to the turntable 320 is fixed on the inner side of the moving block 326, and a third switch 327 electrically connected to the first motor 318 is installed on one side of the moving block 326. In the process of the first motor 318 driving the turntable 320 to rotate, under the pressing action of the pressing plate 325 on the inclined surface of the moving block 326, the moving block 326 slides toward the inner side of the turntable 320, and the second spring 328 is compressed so as not to hinder the turntable 32 0, a protrusion is provided on one side of the moving block 326 located at the third switch 327, so that when the moving block 326 leaves the pressing plate 325 and the second spring 328 drives the moving block 326 to reset, the third switch 327 will not touch the pressing plate 325, thereby preventing the third switch 327 from being misoperated; a detector 329 is installed on the connecting tube 28, and the three detectors 329 are respectively electrically connected to the electromagnetic blocks 32 in the three mounting tubes 31. The detector 329 can detect the vinegar concentration based on the electrochemical sensing technology, using the current generated by the chemical reaction, or based on the photoionization detection technology, using high-energy ultraviolet rays to ionize the acetic acid molecules, and detecting the vinegar concentration by measuring the generated current, so that the three detectors 329 can respectively detect the vinegar in the upper layer, the middle layer and the lower layer after sampling; When the detector 329 detects vinegar, the generated current can make the electromagnetic block 32 produce a repulsive effect on the magnetic block 35, so that the slider 33 drives the connecting rod 36 and the connecting piece 38 to move away from the electromagnetic block 32, and the first spring 37 is compressed, thereby driving the rotation of the rotating plate 39. When the concentration of vinegar is relatively high, the repulsive effect on the magnetic block 35 can be relatively large, so that the moving distance of the slider 33 is relatively large, so that the operator can also judge the concentration of the vinegar according to the moving distance of the slider 33 to judge whether the relevant preparation of the vinegar needs to be adjusted. For the vinegar in the upper layer, middle layer and lower layer of the fermentation tank 11, when the difference in vinegar concentration between any two layers is relatively large, the rotation amplitude of one or more rotating plates 39 can be relatively large, so that the rotating plate 39 drives the pressing block 313 to rotate around the L-shaped rod 311 with a large amplitude, so that the pressing block 313 presses the first switch 315 on one side, so that the first motor 318 works and drives the turntable 320 to rotate, so that the connecting block 324 rotates to the other side of the mounting block 321, and presses the gear switch 322 and the second switch 323 on the other side of the mounting block 321. The pressing action of the second switch 323 on the other side of the mounting block 321 stops the first motor 318 from working. The pressing of the gear switch 322 on the other side of the mounting block 321 can shorten the interval time of the sampling component 2 for sampling vinegar to 1 / 3 of the set time, so as to increase the number of sampling and testing of vinegar, timely adjust the fermentation of vinegar, and make the fermentation of vinegar quickly recover to the requirements. At the same time, the connection block 324 presses the gear switch 322 on the other side of the mounting block 321, which can increase the power of the stirring motor 12 and increase the stirring time of the stirring member 13 driven by the stirring motor 12 to stir the vinegar in the fermentation tank 11, so as to stir the vinegar more fully and evenly and improve the fermentation effect of the vinegar. When 1 / 3 of the set time is reached later, the sampling component 2 will sample the vinegar and detect it through the detector 329. When the difference between the detected upper layer, middle layer and lower layer of vinegar is small, the pressing block 313 will not press the first switch 31. 5. A distance sensor may also be provided on the inner side of the side of the mounting cylinder 31 away from the electromagnetic block 32. When the distance sensor detects a change in the moving distance of the slider 33 and the first switch 315 is not pressed, the second motor 319 may drive the pressing plate 325 to rotate 180 degrees, and the first motor 318 may drive the turntable 320 to rotate in the opposite direction. When the upper moving block 326 rotates to the position of the pressing plate 325 along with the turntable 320, the pressing plate 325 may press the third switch 327 to stop the first motor 318 from working. When the set time is reached again in the subsequent period of 1 / 3, if the detection The difference between the measured vinegar is also small, and the second motor 319 can drive the pressing plate 325 to rotate 180 degrees away from the upper moving block 326, so as to release the pressing effect of the pressing plate 325 on the third switch 327 on the upper moving block 326, so that the first motor 318 can drive the turntable 320 to rotate in the opposite direction. When the lower moving block 326 rotates to the position of the pressing plate 325 with the turntable 320, the pressing effect of the pressing plate 325 on the third switch 327 stops the first motor 318. When the set time is reached again, if the detected The difference between the vinegar is still small. Similarly, the first motor 318 can drive the turntable 320 to rotate in the opposite direction again. When the connecting block 324 rotates in the opposite direction with the turntable 320 to the initial position, that is, rotates to one side of the mounting block 321, the connecting block 324 can press the gear switch 322 and the second switch 323 on one side of the mounting block 321. The pressing effect of the second switch 323 on one side stops the first motor 318 from working. The pressing effect of the gear switch 322 on one side causes the controller to control the sampling component 2 to restore the interval time of vinegar sampling to the initial set time. When the vinegar is sampled and tested every time 1 / 3 of the set time is reached, if the difference between the vinegars detected in the middle is large, the pressing block 313 will press the first switch 315 again, so that the first motor 318 drives the turntable 320 to rotate, so that the connecting block 324 rotates with the turntable 320 to the other side of the mounting block 321 again, that is, when the difference between the vinegars detected three times in a row is not large, the initial sampling set time interval can be restored to ensure that the fermentation of the vinegar meets the requirements and the effect of the vinegar fermentation is guaranteed.
