[0043] Reference Figures 1-5 The present application provides a kind of fermentation tank sampling device for wine-making of grains, comprising:

[0044] Sampling box body 2 is fixedly connected at the top of fermentation tank 1, and disinfection part is arranged in sampling box body 2. The inner side top of fermentation tank 1 is provided with transition shell 9, and transition sealing door part is arranged between the top and the bottom of transition shell 9. The sidewall bottom of sampling box body 2 is provided with box door 18.

[0045] Sampling assembly, including setting in sampling box body 2 sampling shell 7, sampling shell 7 and sampling box body 2 are provided with lifting mechanism, the bottom of sampling shell 7 is communicated with sampling pipe 8, the bottom end of sampling pipe 8 is extended into fermentation tank 1 through transition sealing door part, and the bottom of sampling pipe 8 is provided with sealing mechanism. When the bottom of sampling pipe 8 extends to the predetermined depth, sealing mechanism makes wine sample enter into sampling pipe 8.

[0046] The main function of the sampling box 2 is to ensure that the sampling tube 8 is not in contact with the outside during sampling; the main function of the disinfection part is to disinfect the sampling tube 8 before sampling to avoid the occurrence of bacterial contamination in the fermentation tank 1; the main function of the transition sealing door part is to ensure that the fermentation tank 1 is always in a sealed state during the process that the sampling tube 8 extends into the fermentation tank 1; the main function of the lifting mechanism is to drive the sampling shell 7 to move up and down, thereby driving the sampling tube 8 to move up and down in the fermentation tank 1, so that the bottom of the sampling tube 8 is at a predetermined position in the fermentation tank 1; the main function of the sealing mechanism is to ensure that the wine sample enters the sampling tube 8 only after the sampling tube 8 reaches the predetermined depth, so as to ensure accurate sampling. Overall, the present application sets the sampling tube with adjustable height, so that the sampling tube can accurately obtain the wine sample at any position in the fermentation tank, and the wine sample is not affected by other depth wine samples, and by setting the transition shell and the transition sealing door part, the fermentation tank can be kept in a sealed state during the sampling process, thereby reducing the influence of the sampling process on the fermentation of the wine sample.

[0047] Further optimization scheme, the sealing mechanism includes a second motor 20 vertically fixedly connected in the sampling shell 7, one end of the output shaft of the second motor 20 is coaxially fixedly connected with a second lead screw 21, the other end of the second lead screw 21 is threadedly sleeved with a sliding rod 22, the sliding rod 22 is vertically slidably connected in the sampling tube 8 through a limiting piece, the bottom end of the sliding rod 22 is fixedly connected with a sealing rubber pad 23, the inside of the bottom opening of the sampling tube 8 is fixedly connected with a blocking ring 24, and the sealing rubber pad 23 and the blocking ring 24 are correspondingly arranged.

[0048] As shown in Figure 1 , Figure 4 and Figure 5 , a threaded hole 26 is formed in the top of the sliding rod 22 downward, and the sliding rod 22 is in transmission connection with the second lead screw 21 through the threaded hole 26.

[0049] During the process that the sampling tube 8 extends into the fermentation tank 1, the sealing rubber pad 23 is attached to the blocking ring 24, so that the wine sample can be prevented from entering the sampling tube 8. When the sampling tube 8 moves to the predetermined depth, the second motor 20 rotates to drive the second lead screw 21 to rotate, and the second lead screw 21 drives the sliding rod 22 to move upward through threaded transmission, so that the sealing rubber pad 23 is separated from the blocking ring 24, and the bottom opening of the sampling tube 8 is opened, and the wine sample can automatically enter the sampling tube 8 under the gas pressure in the fermentation tank 1. After an appropriate amount of wine sample is obtained, the second motor 20 is reversely rotated to re-abut the sealing rubber pad 23 on the blocking ring 24, so as to prevent the wine sample from continuously flowing into the sampling tube 8.

[0050] Further optimization scheme, the limiting piece includes a fixed frame 25, the fixed frame 25 is slidably sleeved on the sliding rod 22, and the fixed frame 25 is fixedly connected in the sampling tube 8 through a plurality of supporting rods 27. The fixed frame 25 is used to prevent the sliding rod 22 from rotating with the second lead screw 21.

[0051] As Figure 5 shown in the embodiment, the profile of the fixed frame 25 and the sampling tube 8 is set as a rectangle, that is, the sampling tube 8 can be prevented from rotating with the second screw rod 21 by the fixed frame 25. Meanwhile, the fixed frame 25 can ensure the stable movement of the sampling tube 8, so that the sealing rubber pad 23 and the blocking ring 24 can be closely fitted.

[0052] In a further optimization scheme, the top of the sampling tube 8 is in communication with the inside of the sampling shell 7, and a negative pressure control mechanism is arranged between the sampling shell 7 and the sampling box 2.

[0053] In a further optimization scheme, the negative pressure control mechanism comprises a negative pressure connecting pipe 14 fixedly connected to the side wall of the sampling box 2, a hose 19 in communication between one end of the negative pressure connecting pipe 14 and the sampling shell 7, a negative pressure generating device in communication with the other end of the negative pressure connecting pipe 14, and a pressure gauge 15 and an electromagnetic valve 29 in communication with the negative pressure connecting pipe 14.

[0054] As Figure 3 shown, before opening the sealing rubber pad 23, the electromagnetic valve 29 can be opened and the negative pressure generating device can be controlled to operate to create a negative pressure environment in the sampling shell 7 and the sampling tube 8. When the sampling tube 8 is inserted to a predetermined depth and the wine sample is obtained, the negative pressure environment in the sampling shell 7 and the sampling tube 8 can ensure that the wine sample automatically flows into the sampling tube 8 and the sampling tube 8 is always in a negative pressure state before the sealing rubber pad 23 is closed again, which can effectively prevent the wine sample in the sampling tube 8 from flowing back into the fermentation tank 1, even if the air pressure in the fermentation tank 1 is slightly low, the sampling process will not appear backflow, thereby effectively avoiding the occurrence of pollution.

[0055] The main function of the pressure gauge 15 is to enable the operator to understand the air pressure state in the sampling tube 8 during the sampling process, and to ensure that the wine sample in the fermentation tank 1 always flows into the sampling tube 8 by avoiding the positive pressure of the pressure gauge 15.

[0056] In a further optimization scheme, the transition sealing door piece comprises a first opening 12 formed in the bottom of the transition shell 9, the bottom of the transition shell 9 is fixedly connected with a hinged seat 11, the hinged seat 11 is hingedly connected with a sealing plate 10, the sealing plate 10 is matched with the first opening 12, a coil spring is arranged between the sealing plate 10 and the hinged seat 11, the coil spring is used to make the sealing plate 10 buckled in the first opening 12, and an automatic sealing piece is arranged between the fermentation tank 1 and the sampling box 2.

[0057] As Figure 3 shown, the main function of the coil spring is to always buckle with the first opening 12 when the sealing plate 10 is not pushed by the sampling tube 8, thereby maintaining the air tightness of the fermentation tank 1. Meanwhile, due to the existence of the fermentation gas in the fermentation tank 1, the air pressure in the fermentation tank 1 can further push the sealing plate 10 to be closely buckled in the first opening 12.

[0058] To further optimize the solution, the automatic seal includes a second opening 28 opened on the top of the fermentation tank 1, the sampling box 2 is connected to the transition shell 9 through the second opening 28, and a sealing ring 13 is fixedly connected to the inner side of the second opening 28, and the sealing ring 13 is adapted to the outer wall of the sampling tube 8.

[0059] like Figures 1-3 As shown, when sampling is required, the sampling tube 8 first descends and engages with the sealing ring 13. Then, as the sampling tube 8 continues to descend, it pushes the sealing plate 10 open, and the bottom of the sampling tube 8 extends into the fermenter 1. During this process, the sealing ring 13 and the sampling tube 8 are in contact, which ensures that the fermenter 1 remains sealed. When sampling is completed, the sampling tube 8 ascends. When the bottom of the sampling tube 8 is lifted up and positioned in the transition housing 9, the sealing plate 10 is re-engaged in the first opening 12 under the action of the coil spring, sealing the fermenter 1. At this time, the sampling tube 8 continues to rise and separate from the sealing ring 13 without affecting the sealing of the fermenter 1.

[0060] To further optimize the solution, the lifting mechanism includes a slide rail 6 fixedly connected to the side wall of the sampling box 2, a slider 17 is vertically slidably connected inside the slide rail 6, the sampling shell 7 is fixedly connected to the slider 17, a first screw rod 16 is vertically rotatably connected inside the slide rail 6, the slider 17 is threadedly mounted on the first screw rod 16, and a first motor 5 is fixedly connected to the top of the slide rail 6, and the first motor 5 is transmission-connected to the first screw rod 16.

[0061] like Figure 3 As shown, when the sampling tube 8 needs to be lowered, the first motor 5 rotates, driving the first screw 16 to rotate. The slider 17 drives the sampling housing 7 downward along the slide rail 6 under the action of the threaded transmission, thereby driving the sampling tube 8 to descend. When the sampling tube 8 needs to be raised, the first motor 5 is controlled to rotate in the opposite direction.

[0062] According to a further optimized solution, the disinfection unit includes a plurality of disinfection lamps 4 , which are vertically fixedly connected to the sampling box 2 .

[0063] like Figure 1 As shown, the main function of the several disinfection lamps 4 is to disinfect the interior of the sampling box 2 and the surface of the sampling tube 8 to avoid bacterial contamination during the sampling process.

[0064] According to a further optimized solution, a partition 3 is fixedly connected to the inner wall of the sampling box 2, and the first motor 5 and the disinfection lamp 4 are respectively located at the upper and lower parts of the partition 3.

[0065] like Figure 1 As shown, the main function of the partition 3 is to isolate the first motor 5 from the sampling tube 8 to avoid contamination of the sampling tube 8 to the greatest extent.

[0066] Further optimization scheme, still be provided with control unit, control unit's main function is control first motor 5, second motor 20 and solenoid valve 29's operation.

[0067] The working process of the embodiment is as follows: before sampling, a negative pressure environment is created in the sampling shell 7 and the sampling tube 8 by the negative pressure generating device. Then the solenoid valve 29 is closed, the first motor 5 is controlled to drive the sampling shell 7 to descend, the sampling tube 8 passes through the sealing ring 13 and the sealing plate 10 in turn and enters the fermentation tank 1, and finally stops at a predetermined depth in the fermentation tank 1. Then the second motor 20 is controlled to lift the sliding rod 22 by a certain distance, so that the sealing rubber pad 23 is separated from the sealing ring 24, and the wine sample at the predetermined depth enters the sampling tube 8 under the action of the air pressure in the fermentation tank 1 and the negative pressure in the sampling tube 8. By observing the pressure gauge 15, the second motor 20 is reversed before the pressure gauge 15 returns to positive pressure, so that the sealing rubber pad 23 re-presses the sealing ring 24, and the sampling tube 8 is sealed.

[0068] Finally, the first motor 5 lifts the sampling tube 8 to the sampling box 2, opens the box door 18, places the container at the bottom of the sampling box 2, and opens the solenoid valve 29 and the sealing rubber pad 23 to make the wine sample in the sampling tube 8 flow into the container, realizing the acquisition of the wine sample.
