Description

Technical Field

[0001] The invention relates to the technical field of wine making, in particular to a wine storage tank and a stratified sampling device thereof. Background Art

[0002] In the process of wine brewing and storage, wine storage tanks play an extremely critical role. They are important containers to ensure that the wine can be stably stored and gradually aged after brewing. With the large-scale development of the winemaking industry and the continuous improvement of the requirements for refined control of wine quality, large wine storage tanks are being used more and more widely. These large wine storage tanks can often hold considerable amounts of wine, and the storage period of the wine in them is relatively long, usually lasting for months or even years.

[0003] During the long-term storage process, due to the combined influence of the physical properties of the wine itself and the environmental factors in the tank, the wine is not in a uniform state in the tank, but forms obvious differences in different layers. In terms of physical properties, the density of the wine will change with the changes in alcohol content, sugar content and other dissolved substance concentrations. This leads to the distribution of wines with different alcohol content and ingredients in the tank under the action of gravity. From the perspective of chemical properties, during the fermentation and aging process, the generation and conversion rates of various flavor compounds such as esters, aldehydes, alcohols, etc. are not uniformly synchronized in the entire tank. The wine near the tank wall or bottom may form flavor substances different from the upper layer of wine due to factors such as contact with the tank material, slight changes in local temperature and pressure, etc. At the same time, the distribution of microbial communities also shows a stratified phenomenon in the wine storage tank. Some microorganisms that prefer specific environmental conditions (such as temperature, oxygen content, alcohol content range, etc.) will gather and grow at different locations in the tank. They have different degrees of influence on the chemical reaction process of the wine, such as fermentation and esterification, which leads to changes in the flavor and quality characteristics of the wine at different levels.

[0004] Therefore, in order to comprehensively and accurately grasp the quality status of the wine at different depths in the tank, there is an urgent need for a wine storage tank and a stratified sampling device that can store base wine and sample base wine at different heights.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0036] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0037] The specific embodiments are as follows:

[0038] like Figures 1 to 6 As shown; the present invention discloses a layered sampling device, comprising an outer shell 1, the outer shell 1 comprises a left end 11, a cylinder 12 and a right end 13 which are detachably connected from left to right, a through hole 14 is opened in the left end 11 along the axial direction, a special-shaped hole 15 is opened in the right end 13, a sampling port 16 and a sewage outlet 17 are opened at the bottom of the cylinder 12, a first solenoid valve is installed at the sampling port 16, and a second solenoid valve is installed at the sewage outlet 17;

[0039] The push assembly 2 includes a push rod 21, a stopper 22 and a piston 23. One end of the push rod 21 passes through the through hole 14, the cylinder 12 and the special-shaped hole 15 from left to right in sequence, and the push rod 21 is slidably connected to the left end 11. The stopper 22 is fixed to the portion of the push rod 21 extending from the left end 11. The piston 23 is fixedly connected to one end of the push rod 21. The push rod 21 is axially provided with a hollow cavity. An air inlet 24 and an air outlet 25 communicating with the hollow cavity are provided on the push rod 21. The air inlet 24 is located on the portion of the push rod 21 extending into the cylinder 12, and the air outlet 25 is located on the left side of the stopper 22.

[0040] A first conical surface 26 and a convex ring 27 are provided on the inner wall of the right end portion 13. One end of the push rod 21 passes through the convex ring 27 and is slidably connected with the convex ring 27. A plurality of liquid inlet holes 271 are provided on the convex ring 27. A second conical surface 28 capable of matching with the first conical surface 26 is provided on the outer wall of the piston 23. When the first conical surface 26 contacts the second conical surface 28, the air inlet hole 24 is closed by the hole wall of the left end portion 11. When the first conical surface 26 separates from the second conical surface 28, the air inlet hole 24 is connected with the inside of the cylinder 12.

[0041] A telescopic motor 3 is fixed on the top of the left end portion 11, and the telescopic motor 3 is fixedly connected to the end of the push rod 21 away from the piston 23 through a connecting piece 34;

[0042] The air blowing assembly 4 is communicated with the interior of the cylinder 12;

[0043] A cleaning assembly 5, the cleaning assembly 5 is communicated with the interior of the cylinder 12;

[0044] The controller 6 is electrically connected to the first solenoid valve, the second solenoid valve, the telescopic motor 3, the blowing component 4 and the cleaning component 5.

[0045] The left end 11, the cylinder 12, and the right end 13 of the outer shell 1 of the present invention are detachably connected, so that each part is easy to disassemble and assemble. Whether it is daily inspection, component repair and replacement, or deep cleaning of the interior, it can be easily carried out, ensuring the hygiene and efficiency of the sampling process;

[0046] Secondly, the push rod 21 of the present invention slides axially in the through hole 14, and the push rod 21 is controlled to slide by the telescopic motor 3, so that the second conical surface 28 on the piston 23 can accurately contact or separate with the first conical surface 26 of the inner wall of the right end portion 13. When in contact, the cylinder 12 can be closed to prevent the wine from accidentally flowing out or foreign impurities from entering; when separated, the wine can enter the cylinder 12 through the liquid inlet hole 271 on the convex ring 27, open the first solenoid valve, and then make the liquid flow to the sampling port 16 to achieve sampling;

[0047] The present invention provides a limiter 22, which is provided at the portion of the push rod 21 extending out of the left end portion 11, and can limit the sliding range of the push rod 21, so as to prevent the push rod 21 from excessively sliding and disengaging from the through hole 14, etc., thereby ensuring the stability of the entire push assembly 2 during operation; at the same time, a spring 29 is provided between the boss and the piston 23 so that the second conical surface 28 tends to separate from the first conical surface 26, which helps to maintain a certain initial state under normal conditions, and provides appropriate elastic force assistance during operation, further ensuring the smoothness of the sliding action and the safety of the overall use of the device;

[0048] The present invention provides an air inlet 24 and an air outlet 25 on the push rod 21, and when the first cone 26 contacts the second cone 28, the air inlet 24 is closed by the left end 11, and when the first cone 26 and the second cone 28 are separated, the air inlet 24 is connected with the inside of the cylinder 12. This ingenious design realizes the reasonable control of the air path at different sampling stages; when no sampling is taken, the inside of the cylinder 12 is ensured to be in a closed space to prevent external gas from entering at will to affect the state of the wine or cause leakage; and when sampling, the wine can flow through the air path. When the wine enters the cylinder 12, the air originally in the cylinder 12 is discharged to the outside through the air inlet 24 and the air outlet 25, which is beneficial to the stability of the air pressure inside the cylinder 12, the flow of the wine, and the optimization of the sampling process.

[0049] In this embodiment, the left end portion 11 is connected to the cylinder 12 by threads, and the cylinder 12 is connected to the right end portion 13 by threads. A rubber ring is provided at the connection between the left end portion 11 and the cylinder 12 and at the connection between the right end portion 13 and the cylinder 12.

[0050] The threaded connection method of the present invention allows the various parts to be easily separated or reconnected when they need to be disassembled or assembled; specifically, when the equipment is initially installed, regularly maintained, or a component fails and needs to be replaced, the staff can easily separate or reconnect the left end portion 11, the cylinder 12, and the right end portion 13, which greatly improves the convenience of operation and reduces the time and labor cost consumed in the equipment maintenance and assembly process;

[0051] The present invention arranges a rubber ring to seal the threaded connections of the left end portion 11, the cylinder 12 and the right end portion 13. Since the rubber ring has good elasticity and plasticity, when the left end portion 11 and the cylinder 12, as well as the right end portion 13 and the cylinder 12 are assembled and tightened through threaded connections, the rubber ring will be squeezed and deformed, thereby tightly filling the gap in the connection, thereby forming a reliable sealing defense line, which greatly prevents wine from seeping out of these connection portions, ensuring that the interior of the wine storage tank is always in a good sealing state, playing a key role in the long-term storage of wine and maintaining the stability of the quality of wine, and avoiding waste caused by leakage of wine and possible health and safety problems.

[0052] In this embodiment, felt rings are provided at the connection between the through hole 14 and the push rod 21 and at the connection between the protruding ring 27 and the push rod 21 .

[0053] The present invention arranges a felt ring at the connection between the push rod 21 and the through hole 14, and between the convex ring 27 and the push rod 21. Since the felt ring is fine and soft, it fills in the gap at the connection and can effectively prevent the wine from seeping out of the gap, further improving the sealing effect here; in the actual sampling process, when the push rod 21 performs an axial sliding operation, the felt ring can adaptively deform with the movement of the push rod 21, always maintaining the sealing effect on the gap, ensuring that the wine inside the wine storage tank will not leak due to poor sealing at the connection, maintaining a relatively closed and stable environment inside the wine storage tank and the layered sampling device, which is conducive to The wine is properly stored and the sampling work is accurately carried out. The push rod 21 frequently slides in the through hole 14 and the convex ring 27. If there is direct contact and friction between the two, it is easy to cause wear of the contact surface, affecting the sliding smoothness of the push rod 21 and the service life of the device; the presence of the felt ring is equivalent to a lubricant, and its soft material can reduce the friction between the push rod 21 and the wall of the through hole 14, making the sliding of the push rod 21 smoother and easier, reducing the mechanical loss caused by friction between components, extending the service life of the push rod 21 and the related structures of the through hole 14, and reducing the frequency of equipment maintenance.

[0054] In this embodiment, the piston 23 is a cork stopper, a protrusion 231 is provided at the left end of the piston 23, magnets 232 are embedded on both sides of the protrusion 231, a rubber ring 2 is provided at the connection between the right end 13 and the piston 23, and a magnet 2 131 attracted to the magnet 1 232 is embedded in the right end 13.

[0055] The piston 23 of the present invention is made of cork. Since cork itself is soft, elastic and fine, it can fit well on the inner wall of the corresponding cavity, effectively fill the gap and form the first sealing line of defense. The use of a rubber ring further enhances the sealing effect, greatly preventing the wine from seeping out from around the piston, ensuring the effective isolation of the internal space of the sampling device from the outside world, and playing a key role in maintaining the sealing of the space where the wine is located and preventing the wine from leaking during the sampling process; secondly, the present invention sets magnet 1 232 and magnet 2 131 through the attraction between the magnets. The suction force of the magnets can ensure that the piston will not move arbitrarily due to slight shaking, vibration, power failure and other factors, and can make the piston in a relatively stable position in the device.

[0056] In this embodiment, the telescopic motor 3 includes a motor 31, a gear 32 and a fixed rod 33. The motor 31 is fixed at the top of the left end portion 11, and the output end of the motor 31 is fixedly connected to the gear 32. A rack meshing with the gear 32 is provided on the fixed rod 33. A fixed block 35 is fixed at the top of the left end portion 11. The top of the fixed block 35 contacts the bottom end of the fixed rod 33. One end of the fixed rod 33 is fixedly connected to one end of the connecting member 34. The end of the push rod 21 away from the piston 23 is fixedly connected to the other end of the connecting member 34. The controller 6 is electrically connected to the motor 31.

[0057] In some other embodiments, a groove is formed at the top of the fixing block 35, and the fixing rod 33 slides in the groove.

[0058] The present invention can realize precise displacement control of the fixed rod 33 through the meshing transmission mode of the motor 31, the gear 32 and the rack on the fixed rod 33. The cooperation between the gear 32 and the rack has high transmission accuracy. The motor 31 rotates a certain angle to drive the gear 32 to rotate accordingly, thereby accurately driving the fixed rod 33 to move a specific distance along the set direction, so that the push rod 21 connected to the fixed rod 33 can accurately reach the expected position, and a fixed block 35 is provided to support the fixed rod 33 to ensure that the fixed rod 33 can always move left and right along the axial direction. In the stratified sampling device, the contact or separation state of the piston 23 and the right end 13 can be accurately controlled to achieve precise sampling of the wine, thereby effectively improving the accuracy and repeatability of the sampling.

[0059] In this embodiment, the blowing assembly 4 includes an air compressor 41, a blowing pipe 42 and a nozzle 43. The nozzle 43 is installed on the inner wall of the cylinder 12. One end of the blowing pipe 42 is connected to the air compressor 41, and the other end is connected to the nozzle 43. The controller 6 is electrically connected to the air compressor 41.

[0060] After the sampling operation is completed, some wine and some impurities such as sediment and tiny particles in the wine often remain inside the cylinder 12. The air compressor 41 introduces gas into the cylinder 12 through the blowing pipe 42 and the nozzle 43. The flow and impact force of the gas can be used to blow the remaining wine and impurities away from the wall of the cylinder 12 and discharge them into the liquid collection bottle, thereby effectively cleaning the inside of the cylinder 12, avoiding the accumulation of impurities that affect the accuracy of the next sampling and the quality of the wine, and ensuring the cleanliness of the internal environment of the cylinder 12 each time sampling is taken.

[0061] In this embodiment, the cleaning component 5 includes a water pump 51, a water pipe 52 and a nozzle 53. The nozzle 53 is installed on the inner wall of the cylinder 12. One end of the water pipe 52 is connected to one end of the water pump 51, and the other end of the water pipe 52 is connected to the nozzle 53. The other end of the water pump 51 is connected to an external water source, and the controller 6 is electrically connected to the water pump 51.

[0062] The nozzle 53 of the present invention is installed on the inner wall of the cylinder 12, so that the cleaning water can be sprayed from various positions in the cylinder 12, thereby achieving all-round and no-dead-angle coverage of the interior of the cylinder 12; through the multi-angle and uniform spraying of the nozzle 53, it can be ensured that the entire interior of the cylinder 12 is fully cleaned, and wine stains, impurities, microorganisms and other substances that may affect the quality of the wine and the accuracy of sampling are effectively removed, creating a good and clean environment for subsequent wine storage and sampling work.

[0063] In this embodiment, the limiting member 22 is a limiting pin or a limiting ring.

[0064] In the stratified sampling device for wine storage tanks of the present invention, the push rod 21 needs to slide axially in the through hole 14 to realize the corresponding sampling function. The limit pin or the limit ring serves as the limit member 22, which can clearly define the sliding range of the push rod 21, thereby preventing the push rod 21 from disengaging from the through hole 14 due to exceeding a reasonable range during the sliding process, preventing the push rod 21 from colliding with or being damaged by other parts of the device, and ensuring that the push rod 21 always moves within a predetermined and safe range, thereby ensuring that the entire pushing assembly 2 and the entire sampling device can operate stably and reliably.

[0065] A wine storage tank includes a plurality of stratified sampling devices and a tank body 7, wherein a plurality of legs 78 are fixed to the bottom end of the tank body 7, a feed port 71 is arranged at the top end of the tank body 7, a discharge port 72 is arranged at the bottom end, a sealing cover 73 is arranged on the feed port 71, a solenoid valve 74 is arranged on the discharge port 72, a plurality of circular holes 77 are opened on the side wall of the tank body 7, and a stratified sampling device is arranged at each of the circular holes 77, a right end portion 13 is fixedly connected to the side wall of the tank body 7 located around the circular hole 77, a sampling box 8 is installed on the side wall of the tank body 7, a plurality of sampling slots 81 are arranged in the sampling box 8, the sampling slots 81 correspond to the sampling ports 16 one by one, and each sampling slot 81 is connected to the sampling port 16 through a sampling tube 18, and a sewage outlet 17 is connected to an external sewage tank through a sewage pipe 19;

[0066] The controller 6 is installed on the outer wall of the wine storage tank, and the controller 6 is electrically connected to the solenoid valve 74 .

[0067] In this embodiment, the plurality of sampling slots 81 in the sampling box 8 are numbered from left to right, corresponding to the sampling devices arranged in sequence from high to low, and the wine samples taken from the corresponding heights flow into the corresponding sampling slots 81 in sequence.

[0068] In this embodiment, a mounting frame is fixed on the side wall of the tank body 7, and the sampling box 8 is installed on the mounting frame. The sampling box is used to conveniently collect base wine samples of different heights at one time, and the mounting frame is located at a low position, which is convenient for taking.

[0069] The stratified sampling device of the present invention cooperates with the tank body 7 to form a complete wine storage and quality monitoring system. The tank body 7 is responsible for providing a stable storage space for the wine, and the stratified sampling device can sample and test the wine at different height levels as needed during the storage of the wine, and realize the normal entry and exit of the wine through the feed port 71 and the discharge port 72, thereby jointly ensuring the stable quality of the wine during the storage process, and also facilitating the understanding of the quality changes of the wine at any time, providing strong support for the production and management of the wine.

[0070] In this embodiment, the tank body 7 includes a double-layer wall body, the inner wall body 75 is nested in the outer wall body 76, the inner wall body 75 is a clay layer made of Nixing clay, and the outer wall body 76 is a metal layer made of stainless steel material.

[0071] The present invention adopts a double-layer wall setting, in which Nixing clay has a unique microporous structure and good air permeability. The inner wall 75 is a clay layer, which can enable the wine to have a moderate gas exchange with the outside world during storage. This slow and stable gas exchange is conducive to the oxidation reaction of the wine, creating more favorable conditions for the aging of the wine, and can promote the better fusion and transformation of the flavor substances in the wine, making the taste of the wine mellower and the aroma richer, thereby improving the quality of the wine. The outer stainless steel metal layer has high strength and hardness, and can provide good physical protection for the tank body 7. It can effectively resist possible physical damage such as collisions and impacts from the outside world, prevent the tank body 7 from breaking or deforming due to accidental impacts, and ensure the safety of wine storage. Especially in some cases where the transportation, handling or storage environment is relatively complex, this powerful physical protection capability is particularly important.

[0072] The working principle of a wine storage tank and a stratified sampling device thereof of the present invention is as follows: when sampling is required, the motor 31 is started to open the first solenoid valve, and the output end of the motor 31 drives the gear 32 to rotate counterclockwise, thereby driving the fixing rod 33 to move axially to the right, and the push rod 21 fixed by the connecting piece 34 moves to the right along with the fixing rod 33, and the second cone surface 28 of the piston 23 is separated from the first cone surface 26 of the right end portion 13. At this time, the interior of the cylinder 12 is connected with the outside through the liquid inlet hole 271 on the convex ring 27. At the same time, the air inlet hole 24 of the push rod 21 is not closed, and the air outlet hole 25 is ventilated normally, so that the liquid enters the cylinder 12, and the gas in the cylinder 12 is discharged. The liquid enters the cylinder 12 and flows to the sampling port 16 at the same time, and flows to the corresponding sampling slot 18 through the sampling tube 18. After the sampling is completed, when the motor 31 drives the push rod 21 to slide to the left, the second cone surface 28 of the piston 23 gradually approaches and finally contacts the right end The first conical surface 26 of the left end 13 is in contact with the air inlet 24, and the air inlet 24 is closed by the hole wall of the left end 11, so that the inside of the cylinder 12 is isolated from the outside world; after the sampling is completed, the motor 31 and the first solenoid valve are turned off, and the second solenoid valve is opened. The water pump 51 conveys clean water from the external water source to the nozzle 53 installed on the inner wall of the cylinder 12 through the water pipe 52. The nozzle 53 sprays the cleaning water evenly at various positions inside the cylinder 12, and uses the impact force of water to comprehensively and deeply clean the inside of the cylinder 12 to remove wine stains, dirt and other impurities. The air compressor 41 works to generate compressed air. The compressed air enters the inside of the cylinder 12 through the blowing pipe 42 and the nozzle 43. When cleaning the residual wine and impurities inside the cylinder 12, the airflow blows these substances away from the wall of the cylinder 12, and the sewage flows to the sewage outlet 17 and flows to the sewage tank through the sewage pipe 19. After the cleaning is completed, the second solenoid valve is closed to keep the inside of the cylinder 12 clean.
