Description

Technical Field

[0001] The present invention relates to the technical field of detection sampling, and particularly to a sampling device for the production detection of Hovenia dulcis wine. Background Art

[0002] As one of the fruit wine categories, the monitoring of the fermentation process of Hovenia dulcis wine relies on a strict sampling and detection procedure. In the production of fruit wine fermentation, to ensure the effective analysis of the fermentation states of each layer in the fermentation tank, static sampling technology is usually adopted. This technology requires the fermentation tank to suspend stirring and close the gas passage, and then samples are collected from the top or side of the tank body through a sampling device. This method is particularly suitable for scenarios where complex samples are obtained. For example, when stratified sampling is implemented for fruit wine, during the static fermentation process, the component differences between different liquid layers are significant, and usually, manual sampling is required to ensure the representativeness of the samples.

[0003] However, under the existing technical system, when an operator uses a handheld fishing tool to sample the fruit wine in the fermentation tank, there are two problems. One is that the relatively large volume of the fishing tool causes significant disturbance during the process of immersing it into the fruit wine. This physical intervention will destroy the original stratified state of the fruit wine in the tank, thereby affecting the stability of the fermentation process and the accuracy of sample analysis. The second is that the operation flexibility of the fishing tool is limited, and it is difficult to reach the samples near the fermentation tank wall, resulting in insufficient sampling coverage, which may affect the accurate assessment of the overall state of the fermentation process. For this reason, we propose a sampling device for the production detection of Hovenia dulcis wine. Summary of the Invention

Specific implementation manner

[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Embodiment 1: Please refer to Figures 1-8 , the present invention provides a technical solution: A sampling device for the production and detection of Hovenia dulcis wine, including a mounting plate 1, and further including: An elastic suction pipe 2, arranged on one side of the mounting plate 1, used to extend into the fermentation tank to suck the fruit wine. Specifically, by only extending the elastic suction pipe 2 into the fermentation tank, the disturbance to the fruit wine can be significantly reduced, and the sampling accuracy can be improved; A longitudinal pushing member 3, arranged on the mounting plate 1 and connected to the elastic suction pipe 2, used to drive the elastic suction pipe 2 to move longitudinally relative to the fermentation tank to switch the suction layer; A plurality of collection bottles 4, arranged on the mounting plate 1, and a switching component 5 is arranged on the mounting plate 1, used to drive the plurality of collection bottles 4 to sequentially switch and dock with the elastic suction pipe 2 when the elastic suction pipe 2 moves longitudinally. There are three collection bottles 4, used to store the upper, middle, and lower layer fruit wine samples in the fermentation tank respectively; An extraction component 6, arranged on the mounting plate 1 and connected to the collection bottle 4, used to suck the fruit wine into the corresponding collection bottle 4; A transverse pushing member 7, arranged on one side of the mounting plate 1 and connected to the elastic suction pipe 2, used to drive the elastic suction pipe 2 to move horizontally within the same layer of the fermentation tank to switch the suction point; Specifically, this device has a convenient layer sampling switching function. By adjusting the longitudinal position of the elastic straw 2 with the longitudinal pusher 3, the target sampling layer can be quickly and flexibly selected. At the same time, by operating the switching component 5, the docking conversion between the collection bottle 4 and the elastic straw 2 can be accurately achieved, so as to efficiently complete the step-by-step collection of fruit wine samples at different layers. At the same time, when the elastic straw 2 sucks the sample, the transverse pusher 7 can be used to drive the elastic straw 2 to achieve a transverse displacement within the same layer space of the fermentation tank, so as to flexibly change the specific position of the suction point. This design effectively expands the sampling coverage range, making the obtained samples more comprehensive. At the same time, during the process of adjusting the sampling position of the elastic straw 2, due to the characteristic that the water-facing area of the straw itself is small, the disturbance degree of the fruit wine liquid in the fermentation tank is low, thereby improving the sampling accuracy.

[0021] The longitudinal pusher 3 includes an L-shaped plate 31 arranged on one side of the mounting plate 1. The elastic straw 2 is connected to the L-shaped plate 31, and a moving plate 32 is fixedly connected to the top end of the L-shaped plate 31. An electric push rod 33 is fixedly connected to the mounting plate 1. One end of the electric push rod 33 slides through the mounting plate 1, and the extending end of the electric push rod 33 is fixedly connected to the moving plate 32. Starting the electric push rod 33 moves the moving plate 32, the L-shaped plate 31, and the elastic straw 2 longitudinally to switch the target sampling layer; A plurality of screw rods penetrate through the mounting plate 1 in a threaded manner. One end of the screw rod is wrapped with rubber, and the other end is fixedly connected with a knob. Therefore, when the device is specifically used, the staff can first rotate the screw rod to a suitable position according to the shape of the fermentation tank, and then open the fermentation tank and slowly insert the straw into the fermentation tank. At the same time, the device body is supported by the screw rod against the outer shell of the fermentation tank.

[0022] The corner of the L-shaped plate 31 is designed in an arc shape. The transverse pusher 7 includes a malleable wire 34 arranged on one side of the elastic straw 2, and a flexible tube 35 that wraps the malleable wire 34 is fixedly connected to one side of the elastic straw 2. The flexible tube 35 is designed with the same material as the elastic straw 2 and is fixedly connected to the malleable wire 34; And a chute 36 with a C-shaped cross-section is opened on one side of the L-shaped plate 31, and the flexible tube 35 is located in the chute 36 and is slidably connected to its inner wall. An electric push rod 37 is fixedly connected to the moving plate 32, and the extending end of the electric push rod 37 is fixedly connected to one end of the malleable wire 34, which is used to push the malleable wire 34 and the elastic straw 2 to slide and extend along the chute 36; Specifically, when the elastic straw 2 moves to the target sampling layer, the negative pressure pump 46 is turned on to suck the fruit wine. At the same time, by starting the electric push rod 37, the malleable wire 34 is pushed to slide along the chute 36 on the L-shaped plate 31, thereby driving the elastic straw 2 to move horizontally and extend within the same sampling layer of the fermentation tank, improving the sampling range.

[0023] The switching component 5 includes a circular ring 38 fixedly connected to one end of the mounting plate 1. A circular plate 39 is rotatably connected within the circular ring 38. A plurality of collection bottles 4 are evenly distributed on the circular plate 39 at equal intervals. One end of the elastic suction pipe 2 is located within the circular ring 38 and fixedly connected to its inner wall. And a connecting pipe 41 is conductively connected to the collection bottle 4. One end of the connecting pipe 41 passes through the circular plate 39 for docking with the elastic suction pipe 2. A driving member 42 connected to the circular plate 39 is provided on the mounting plate 1 for driving the circular plate 39 to rotate.

[0024] The driving member 42 includes an external gear ring 43 fixedly connected to the circular plate 39. A driving motor 44 is fixedly connected to the mounting plate 1. A gear disk 45 meshing with the external gear ring 43 is fixedly connected to the output shaft of the driving motor 44. Starting the driving motor 44 drives the gear disk 45 to rotate, thereby driving the external gear ring 43 and the circular plate 39 to rotate, so as to switch the connection between the connecting pipe 41 on the collection bottle 4 and the elastic suction pipe 2.

[0025] The extraction component 6 includes a negative pressure pump 46 fixedly connected to the mounting plate 1. An L-shaped pipe 47 is conductively connected to the negative pressure pump 46. The L-shaped pipe 47 is conductively connected to a plurality of collection bottles 4. By starting the negative pressure pump 46, fruit wine is extracted into the collection bottles 4.

[0026] The collection bottle 4 includes a bottle body 48 and a bottle cap 49. The bottle body 48 and the bottle cap 49 are detachably connected, which is convenient for the staff to process the fruit wine sample subsequently. And the bottle cap 49 is fixedly connected to the circular plate 39. One end of the connecting pipe 41 is conductively connected to the bottle cap 49. And a waste bottle 51 is installed in the middle of the circular plate 39. The waste bottle 51 includes a bottle body 52 and a bottle cap 53. The bottle cap 53 is also fixedly connected to the circular plate 39. The bottle cap 49 and the bottle cap 53 are conductively connected through a conduit. And a plurality of collection pipes 54 are evenly fixedly connected to the bottle cap 53 at equal intervals. One end of the collection pipe 54 also passes through the circular plate 39. Specifically, multiple collection pipes 54 and connecting pipes 41 are evenly distributed along the circular plate 39 at equal intervals. And an air outlet pipe 55 is conductively connected to one end of the bottle cap 53. One end of the L-shaped pipe 47 is located within the air outlet pipe 55 and rotatably connected to it. Specifically, when the elastic suction pipe 2 finishes sucking the fruit wine on the upper layer, there will inevitably be some residual fruit wine of this layer inside it. If the elastic suction pipe 2 is directly moved to the lower layer for sampling, the residual fruit wine of the upper layer will surely be mixed into the new sample, thus having an adverse impact on the sampling accuracy. To avoid this situation, after the elastic suction pipe 2 is moved to the lower layer, it needs to be docked with the collection pipe 54 first, and then the negative pressure pump 46 is started. The fruit wine of the lower layer is used to wash the residual fruit wine of the upper layer in the elastic suction pipe 2 into the waste bottle 51. After the flushing operation is completed, the elastic suction pipe 2 is then docked with the collection bottle 4 of the lower layer, so as to minimize the pollution situation during the sampling process to the greatest extent.

[0027] One end of the flexible straw 2 is conductively connected to a rigid tube 56, and one end of the shapeable wire 34 is fixedly connected to a connecting plate. The connecting plate is fixedly connected to the outer wall of the rigid tube 56. One end of the limiting rod 63 slides through the connecting plate. Two limiting rings 57 are fixedly connected inside the rigid tube 56. A blocking plate 58 is slidably connected between the two limiting rings 57. One side of the limiting ring 57 in contact with the blocking plate 58 is designed with an inclined surface, and one side of the blocking plate 58 is also designed with an inclined surface. At the same time, a plurality of arc-shaped grooves are evenly opened at equal intervals on the edge of the blocking plate 58 for the circulation of fruit wine and for blocking the rigid tube 56. A spring 59 is installed between one side of the blocking plate 58 and one limiting ring 57; Specifically, when the negative pressure pump 46 is not working, the blocking plate 58 tightly presses the limiting ring 57 on one side by means of the spring 59, thereby blocking the end of the flexible straw 2, and further preventing fruit wine from entering the flexible straw 2 when switching the sampling layer. Only when the negative pressure pump 46 is turned on for suction operation, negative pressure is generated inside the flexible straw 2, thereby overcoming the elastic force of the spring 59, and thus opening the blocking plate 58 to normally suck the fruit wine sample.

[0028] One end of the blocking plate 58 is fixedly connected to a round rod 61. One end of the round rod 61 is fixedly connected to a straight plate 62. One end of the straight plate 62 is fixedly connected to a limiting rod 63. Further, when the flexible straw 2 is in the retracted state, the limiting rod 63 contacts and abuts against the end of the L-shaped plate 31, thereby completely blocking the flexible straw 2. Further, after the flexible straw 2 sucks the fruit wine sample of the upper layer, it is horizontally moved and retracted, and then the negative pressure pump 46 is started again to continuously generate negative pressure inside the flexible straw 2. At this time, the blocking plate 58 is blocked and cannot be opened, so the flexible straw 2 will be flattened. At the same time, most of the remaining fruit wine sample of the upper layer in the flexible straw 2 is also sucked into the collection bottle 4. This operation, on the one hand, ensures complete collection and avoids waste, and on the other hand, relatively reduces the amount of fruit wine required for subsequent flushing (because the amount of the remaining fruit wine of the upper layer in the straw is relatively small), also avoiding waste.

[0029] Example 2: Please refer to Figures 1-9 , the present invention provides a technical solution: Example 2 is optimized on the basis of Example 1; A straight tube 64 is fixedly connected to the mounting plate 1. One end of the straight tube 64 passes through the mounting plate 1 and is conductively connected to an external inert gas supply device. Specifically, after the fermentation tank is opened, inert gas can be filled into the fermentation tank through the straight tube 64 extending into its interior (although the straight tube 64 extends into the fermentation tank, it does not insert into the fruit wine), thereby greatly reducing the probability of external air entering the fermentation tank.
