Description

Technical Field

[0001] The invention relates to the technical field of sampling, in particular to an anti-volatilization liquor sampling device. Background Art

[0002] Baijiu is a general term for Chinese liquors excluding fruit wine and rice wine. Chinese baijiu has a complex aroma with esters as the main body. It uses koji and yeast as saccharification and fermentation agents, and uses starch (sugar) raw materials to brew various types of liquor through cooking, saccharification, fermentation, distillation, aging and blending.

[0003] Sampling is required during the production process of liquor, which can more effectively carry out random inspections at various stages of the production process, more effectively ensure the quality pass rate of the liquor production process, and better guarantee the production safety of the liquor.

[0004] The existing method of sampling liquor generally adopts manual extraction through a sampling tube, that is, the pressure in the sampling tube is controlled to decrease, and the atmospheric pressure is stronger than the pressure inside the tube, so the liquor is pressed into the sampling tube by the atmospheric pressure (similar to the principle of a rubber-tipped dropper or syringe). However, this method makes it difficult to control the sampling amount of liquor and cannot perform quantitative sampling of liquor. Too much sample will cause waste of liquor, and too little sample will require secondary sampling, which increases the workload. Summary of the Invention

[0005] The purpose of the present invention is to provide a white wine sampling device that prevents volatilization, aiming to solve the problem that the white wine sampling method in the prior art cannot perform quantitative sampling of white wine.

[0006] To achieve the above-mentioned objectives, the present invention adopts the following technical solutions: the anti-volatile liquor sampling device comprises a rotating shaft; a shell body rotatably mounted on the rotating shaft; an extraction assembly, the extraction assembly comprising a pressing element arranged on the rotating shaft and a sampling element arranged on the shell body; the sampling element comprises a sampling box, the sampling box has a chamber for accommodating liquor, a liquid inlet hole connected to the chamber is arranged at the bottom of the sampling box, an exhaust hole is also arranged at the top of the sampling box, a piston rod is also arranged on the sampling box, the lower end of the piston rod is connected to the plug plate, and the upper end of the piston rod is connected to the movable part; the pressing element can rotate with the rotation of the rotating shaft, and the pressing element can move between a position of pressing the movable part and a position of disengaging from the movable part. When the pressing element rotates to disengage from the movable part, the plug plate rises, allowing the liquor to enter the chamber of the sampling box. When the pressing element rotates to reset, downward pressure is applied to the movable part, causing the plug plate to descend, so that the liquor is discharged from the liquid inlet hole.

[0007] In order to enable the present invention to have a sampling function, a further technical solution of the present invention is that the clamping element includes a pressure plate and a guide wheel arranged on the rotating shaft, the pressure plate is provided with a first inclined surface, and the guide wheel can guide the movable part to the first inclined surface when the movable part moves, and an elastic part is provided between the movable part and the sampling box.

[0008] In order to enable the present invention to reduce the friction between the guide wheel and the movable part, a further technical solution of the present invention is that the guide wheel is rotatably connected to the rotating shaft through a bearing.

[0009] In order to improve the guiding effect of the movable member moving toward the pressure plate, a further technical solution of the present invention is that a second inclined surface corresponding to the first inclined surface is provided on the movable member.

[0010] In order to enable the present invention to have the effect of saving costs, a further technical solution of the present invention is that the elastic member is a spring.

[0011] In order to make the present invention have the function of sampling, a further technical solution of the present invention is that the pressing element includes a pressing plate, a pressure strip is hinged on the pressing plate, and the pressure strip is hinged to the movable part at one end away from the pressing plate.

[0013] In order to facilitate opening of the sampling port, a further technical solution of the present invention is that a first threaded section is provided on the sleeve, and a second threaded section threadedly connected to the first threaded section is provided on the outer cylinder.

[0014] In order to facilitate opening of the sampling port, a further technical solution of the present invention is that the sleeve is slidably fitted on the inner side of the outer cylinder.

[0015] In order to make the present invention have the function of facilitating the control of the rotation of the housing, a further technical solution of the present invention is that a hand wheel for facilitating rotation is provided on the housing.

[0016] The beneficial effect of the present invention is that by arranging the coordination of the rotating shaft, the shell and the extraction component, when sampling the white wine, the device is first inserted into the white wine, and then the shell is rotated. The rotation of the shell drives the sampling box to rotate, and the rotation of the sampling box drives the movable part to move, so that the movable part is separated from the clamping element. At the same time, the plug plate rises, and the white wine is drawn into the sampling box along the liquid inlet hole for quantitative sampling, which effectively realizes the quantitative sampling of the white wine, thereby avoiding waste caused by excessive sample collection or secondary sampling work caused by insufficient sample collection.

DETAILED DESCRIPTION

[0029] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0030] like Figure 1-6FIG. 1 is an embodiment of the present invention, a white wine sampling device for preventing volatilization, comprising:

[0031] A rotating shaft 1 is used to support the anti-volatile liquor sampling device;

[0032] The housing 2 is rotatably mounted on the shaft 1. A hand wheel is provided on the housing 2 to facilitate rotation of the housing 2 on the shaft 1.

[0033] At least one set of sampling mechanisms, each set of sampling mechanisms includes a blocking component 3 provided on the rotating shaft 1 and two extraction components 4, the extraction components 4 include a pressing element 401 provided on the rotating shaft 1 and a sampling element provided on the housing 2, wherein the housing 2 is provided with a notch for the blocking component 3 and the pressing element 401 to pass through and move;

[0034] The sampling element includes a sampling box 402, which has a chamber for accommodating liquor. The chamber for accommodating liquor in the sampling box 402 can only accommodate the required sample amount, and the sampling amount can be limited. The sampling box 402 is provided with a liquid inlet 403 for allowing liquor to enter the sampling box 402 and an exhaust hole 404 for exhausting gas in the sampling box 402. The liquid inlet 403 and the exhaust hole 404 are both connected to the chamber. The sampling box 402 is also provided with a piston rod, the lower end of the piston rod is connected to a plug plate 405, and the upper end of the piston rod is connected to a movable part 406. The plug plate 405 is located between the liquid inlet 403 and the exhaust hole 404. The plug plate 405 moves up and down to draw liquor from the liquid inlet 403 into the sampling box 402 or push the liquor out of the sampling box 402, and at the same time, the original gas in the sampling box 402 will be discharged through the exhaust hole 404.

[0035] The pressing element 401 is capable of rotating with the rotation of the rotating shaft 1. The pressing element 401 is capable of moving between a position of pressing the movable part 406 and a position of disengaging from the movable part 406. When the pressing element 401 rotates to disengage from the movable part 406, the plug plate 405 rises, allowing the liquor to enter the chamber of the sampling box 402. When the pressing element 401 rotates to return to its original position, downward pressure is applied to the movable part 406, causing the plug plate 405 to descend, thereby discharging the liquor from the liquid inlet 403.

[0036] The clamping element 401 includes a pressure plate 4011 and a guide wheel 4012 arranged on the rotating shaft 1. The pressure plate 4011 is provided with a first inclined surface 4013. When the movable part 406 moves, the guide wheel 4012 can guide the movable part 406 to the first inclined surface 4013. An elastic part 407 is provided between the movable part 406 and the sampling box 402. The elastic part 407 can be a spring. The price of the spring is relatively low, which can save costs. The guide wheel 4012 can be rotatably connected to the rotating shaft 1 through a bearing. The movable part 406 is provided with a second inclined surface 4061 corresponding to the first inclined surface 4013.

[0037] When in use, the device is first inserted into the liquor, and then the housing 2 is rotated. The rotation of the housing 2 drives the sampling box 402 to rotate, and the rotation of the sampling box 402 drives the movable member 406 to move, so that the movable member 406 is separated from the pressure plate 4001. At this time, the elastic force of the elastic member 407 can drive the movable member 406 to move and reset. The movement of the movable member 406 drives the plug plate 405 to move through the piston rod. The plug plate 405 moves to draw the liquor along the liquid inlet hole 403 into the chamber of the sampling box 402, completing the sampling; Rotating the shell 2 in the opposite direction can drive the movable part 406 to move. The movable part 406 first passes through the contact guide wheel 4012 to guide the second inclined surface 4061 of the movable part 406 to the first inclined surface 4013, and then guided by the second inclined surface 4061 and the first inclined surface 4013, so that the pressure plate 4011 presses the movable part 406 to move. The movement of the movable part 406 drives the plug plate 405 to move through the piston rod to squeeze out the white wine in the sampling box 402, thereby completing the discharge of the sample.

[0038] like Figure 10 As shown, as another embodiment of the pressing element 401, the difference from the above embodiment lies in the structure of the pressing element 401. In this embodiment, the pressing element 401 includes a pressing plate 4011, and a pressure strip 4014 is hinged on the pressing plate 4011. The pressure strip 4014 is hinged to the movable part 406 at one end away from the pressing plate 4011.

[0039] When in use, first insert the device into the white wine, and then rotate the shell 2. The rotation of the shell 2 drives the sampling box 402 to rotate, and the rotation of the sampling box 402 drives the movable part 406 to move. The movable part 406 moves and rotates at the hinge of the pressure strip 4014. The pressure strip 4014 rotates at the hinge of the pressure plate 4011, thereby driving the movable part 406 to move through the pressure strip 4014. The movable part 406 moves and drives the plug plate 405 to move through the piston rod. The plug plate 405 moves to draw the white wine along the liquid inlet hole 403 into the chamber of the sampling box 402, completing the sampling; and rotating the shell 2 in the opposite direction can also drive the movable part 406 to move in the opposite direction. The movable part 406 pushes the movable part 406 to move through the transmission of the pressure strip 4014. The movable part 406 moves and drives the plug plate 405 to move through the piston rod to squeeze out the white wine in the sampling box 402, completing the discharge of the sample.

[0040] The setting of the blocking component 3 enables the rotating shell 2 to rotate and drive the two sampling boxes 402 on each sampling mechanism to rotate when sampling a state of liquor. The rotation of the two sampling boxes 402 respectively drives the two movable parts 406 to move, so that the two movable parts 406 are respectively separated from the two pressing elements 401. At this time, the rotation of the shell 2 is stopped, and one of the sampling boxes 402 slides and fits with the blocking component 3 to block the liquid inlet 403 thereon. The chamber of this sampling box 402 is in negative pressure, and no liquor enters this sampling box 402, while the other sampling box 402 can take the liquor along the liquid inlet. The hole 403 is drawn into the sampling box 402 for sampling; when sampling the white wine in another state, first operate the white wine to be in the other state. When the white wine is in the other state, continue to control the rotation of the shell 2 to make the liquid inlet hole 403 in contact with the blocking component 3 separate from the blocking component 3. Similarly, after this sampling box 403 is separated from the blocking component 3, the white wine is drawn into the sampling box 402 along the liquid inlet hole 403 for sampling, thereby realizing one sampling operation to sample the white wine in two states respectively, without the need for repeated sampling operations twice, simplifying the operation steps, improving the convenience of operation, and thus improving work efficiency.

[0041] like Figure 7-9 As shown, in order to extract liquor in different depth ranges, it also includes an outer cylinder 5, which is rotatably connected to the rotating shaft 1 through a sealed bearing, a sampling port 501 is provided on the outer cylinder 5, and a sleeve 6 for opening and closing the sampling port 501 is provided on the outer cylinder 5. The sampling port 501 can be extended to the depth of the liquor to be extracted, and then the sleeve 6 is controlled to open the sampling port 501 to a corresponding size. The liquor at this depth will flow along the sampling port 501 into the outer cylinder 5, so that all sampling mechanisms on the rotating shaft 1 and the shell 2 can extract liquor samples at this depth. A first threaded section is provided on the sleeve 6, and a second threaded section threadedly connected to the first threaded section is provided on the outer cylinder 5. The sleeve 6 can be moved up and down along the outer cylinder 5 by rotating it.

[0042] like Figure 11 As shown, as another embodiment of the connection between the sleeve 6 and the outer cylinder 5, the difference from the above embodiment lies in the structure of the connection between the sleeve 6 and the outer cylinder 5. In this embodiment, the sleeve 6 slides and fits on the inner side of the outer cylinder 5, and the sleeve 6 can be directly slid inside the outer cylinder 5 to open the sampling port 501.
