[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The movement of wine generates liquid flow, which will drive the suspended flocculent precipitation to transfer. The flocculent precipitation will move to the wine outlet position at the bottom of the folded filter, and then adhere to the bottom of the folded filter. When the extrusion device squeezes the folded filter, the bottom of the folded filter is deformed due to mutual squeezing and folding, which not only fixes and retracts the flocculent adhered to the bottom of the folded filter to prevent the flocculent from transferring again, but also does not affect the normal filtering effect of the upper end of the folded filter on the wine;

[0022] 2. Even if some flocs adhere to the upper side of the folded filter, affecting the filtering effect of the folded filter, in the process of wine outlet, the folded filter as a whole will bend and deform when being squeezed, so that the flocs cannot always adhere to the upper part of the folded filter. The fallen flocs will also be transferred to the bottom of the folded filter with the flow of wine.

[0023] 3. During the process of wine discharge, the extrusion device drives the support bar to move downward, so that the impurities on the bottom wall of the wine storage tank are scraped and cleaned by the scraping component, and the impurities are pushed to the outside of the wine storage tank, thereby avoiding the discharge of impurities;

[0024] 4. Before the wine is introduced into the wine storage tank, the air inside the wine storage tank is extracted and discharged by the vacuum pump, and at the same time, the upper extrusion plate moves down to assist the vacuum pump to quickly discharge the gas inside the wine storage tank;

[0025] 5. During the process of discharging the wine, the extrusion plate will move down with the discharge of the wine. The moving block will pull the extension ring to deform during the outward movement. The extension ring and the moving block will scrape and clean the impurities on the bottom wall of the wine storage tank through the arc-shaped bottom edge, and push the impurities to the outside of the wine storage tank. After the wine is completely discharged, the impurities are moved to the edge of the wine storage tank, which is convenient for cleaning;

[0026] 6. After the wine is completely discharged, some wine and impurities will still remain on the bottom wall of the wine storage tank. In order to reduce the subsequent cleaning, the inner side of the scraper component can also scrape and clean the remaining wine and impurities, and transfer these parts of the wine and impurities inward for easy cleaning;

[0027] 7. The wine and impurities that enter the outlet cavity will be transferred to the inside of the collection ring along the inclined arc of the outlet cavity, which is convenient for cleaning the collected impurities when storing the wine. The collection ring can collect a large amount of impurities, extending the cleaning cycle and reducing the use of manpower. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0040] The terms such as "upper", "lower", "left", "right", "middle" and "one" used in the present invention are only for the convenience of description and are not used to limit the scope of the present invention. Changes or adjustments to their relative relationships should be regarded as the scope of the present invention without substantially changing the technical content.

[0041] Reference Figure 1-Figure 10 , a fruit wine anti-oxidation device, comprising: a wine storage tank 1, an extrusion device 3 installed at the upper end of the wine storage tank 1 and a wine outlet tank 2 fixed to the bottom surface of the wine storage tank 1, and a wine guide port is provided between the wine storage tank 1 and the wine outlet tank 2;

[0042] The bottom wall of the wine storage tank 1 is provided with a filter assembly 4, and the filter assembly 4 includes a top plate 41, a folded filter screen 42 and a bottom ring 43. The bottom ring 43 is threadedly connected to the bottom wall of the wine storage tank 1 and is concentrically arranged with the wine guide port. The folded filter screen 42 is a pipe column, and the bottom end is fixedly connected to the bottom ring 43. The top plate 41 is fixedly connected to the upper end of the folded filter screen 42.

[0043] The filter assembly 4 is provided with a plurality of support assemblies 5 in an annular shape on the side thereof, and the plurality of support assemblies 5 are used to support the top plate 41, and the support assemblies 5 include a limit frame 51 and a support bar 52, wherein the limit frame 51 is fixedly connected to the bottom ring 43, and the upper end side edge of the support bar 52 is fixedly connected to the side edge of the top plate 41, and the bottom end slides through the limit frame 51;

[0044] The outer edges of the plurality of support bars 52 are provided with scraping components 6 , and the scraping components 6 are used to clean and scrape impurities on the bottom wall of the wine storage tank 1 .

[0045] In the embodiment of the application of the above technical solution, during the storage of fruit wine, a filter assembly 4 that is convenient for quick installation and removal is set inside the wine storage tank 1. The filter assembly 4 is supported in position by an elastic support bar 52, and the folded filter 42 is fully supported without being fixed to the folded filter 42. When the extrusion device 3 squeezes and exports the fruit wine, it drives the folded filter 42 to fold and deform. During the storage of fruit wine, natural components such as pulp residue and pectin in the fruit wine may gradually settle to form flocculent precipitation. However, since the wine does not flow during the storage process, the product The generated flocculent precipitate will be suspended inside the wine. Only when the wine is discharged, the liquid flow generated by the movement of the wine will drive the suspended flocculent precipitate to transfer, and the flocculent precipitate will move to the wine outlet position at the bottom of the folded filter 42, thereby adhering to the bottom end of the folded filter 42. When the extrusion device 3 squeezes the folded filter 42, the bottom of the folded filter 42 is deformed due to mutual squeezing and folded, which not only fixes and retracts the flocculent adhered to the bottom of the folded filter 42 to prevent the flocculent from transferring again, but also does not affect the normal filtering effect of the upper end of the folded filter 42 on the wine.

[0046] Even if some flocs adhere to the upper side of the folded filter 42, affecting the filtering effect of the folded filter 42, during the process of wine outlet, the folded filter 42 as a whole will bend and deform when being squeezed, making it impossible for the flocs to adhere to the upper part of the folded filter all the time. The fallen flocs will also be transferred to the bottom of the folded filter 42 with the flow of the wine.

[0047] During the cleaning process, the flocs adhering to the folded filter 42 can be quickly cleaned by backwashing, or the flocs can be cleaned by replacing the folded filter 42 to avoid impurities remaining inside the wine storage tank 1.

[0048] Wine will also produce peel residues and granular solid sediments. If these sediments move as the wine is discharged, it is easy to cause blockage of the side of the folded filter 42. During the process of wine discharge, the extrusion device 3 drives the support bar 52 to move downward, so that the scraping component 6 can scrape and clean the solid impurities on the bottom wall of the wine storage tank 1, and push the impurities to the outside of the wine storage tank 1, thereby preventing the impurities from being discharged along with the wine.

[0049] The present invention can filter floccules and solid impurities generated during the storage of fruit wine, thereby ensuring the purity of the derived wine and improving the purity and taste of the wine.

[0050] The preferred technical solution in this embodiment is:

[0051] Reference Figure 5The extrusion device includes a driving motor 31, a telescopic rod 32 and an extrusion plate 33. The driving motor 31 is fixedly installed on the top of the wine storage tank 1, the telescopic rod 32 is fixedly connected to the output end of the driving motor 31, the extrusion plate 33 is fixedly connected to the bottom end of the telescopic rod 32, and is sealingly slidably arranged inside the wine storage tank 1, and a material guiding channel is opened in the middle of the extrusion plate 33.

[0052] During the transfer of fruit wine, sometimes only part of the wine needs to be transferred and not all of the wine needs to be rotated. However, during the transfer of the wine, it will come into contact with the outside air, causing the outside air to be absorbed into the wine, thereby causing oxidation of the wine and affecting the quality of the wine. Therefore, the wine that needs to be discharged needs to be separated from the wine in the wine storage tank 1 to reduce the entry of air.

[0053] After the fruit wine to be stored is introduced into the wine storage tank 1, when part of the fruit wine needs to be introduced into the wine outlet tank 2, the telescopic rod 32 is driven to extend and retract by the driving motor 31, thereby driving the extrusion plate 33 to move downward, and at the same time, the valve between the wine storage tank 1 and the wine outlet tank 2 is opened, and the extrusion plate 33 squeezes the wine into the vacuum wine outlet tank 2, and the extrusion is controlled according to the amount of wine discharged, and then the valve is closed to isolate the wine storage tank 1 from the wine outlet tank 2 again, so as to prevent air from entering the wine inside the wine storage tank 1 during the process of wine discharge, thereby preventing the oxidation of the wine.

[0054] Reference Figure 5 The upper end of the wine storage tank 1 is provided with an exhaust device 7, and the exhaust device 7 includes an exhaust fan 71 and an air guide pipe 72. The exhaust fan 71 is fixedly installed on the upper surface of the wine storage tank 1, one end of the air guide pipe 72 is installed at the output end of the exhaust fan 71, and the other end is connected to the material guide channel.

[0055] In order to ensure that there is no oxygen inside the wine storage tank 1, the air inside the wine storage tank 1 needs to be extracted before the wine is introduced to form a vacuum environment inside the wine storage tank 1, thereby avoiding the oxidation of the introduced wine. Before the wine is introduced into the wine storage tank 1, the air inside the wine storage tank 1 is extracted and discharged by the vacuum pump 71, and at the same time, the upper extrusion plate 33 moves downward to assist the vacuum pump 71 to quickly discharge the gas inside the wine storage tank 1.

[0056] Reference Figure 5 A wine guide tank 10 is provided on the upper surface of the wine storage tank 1, and a wine guide pipe is fixedly connected to the bottom end of the wine guide tank 10, and the other end of the wine guide pipe away from the wine guide tank 10 is connected to the material guide channel.

[0057] After the air inside the wine storage tank 1 is completely discharged, it is connected with the external wine and water through the wine guide tank 10, so that the external wine and water are introduced into the wine storage tank 1 for storage of fruit wine.

[0058] Reference Figure 6-8 The scraping assembly 6 includes a plurality of moving blocks 61 and an extension ring 62. The plurality of moving blocks 61 are respectively fixedly connected to the bottom end of the support bar 52, and a mounting opening is provided in the middle of each moving block 61. The extension ring 62 is fixedly connected between the plurality of moving blocks 61 to fix the plurality of moving blocks 61 into a whole.

[0059] The moving block 61 is λ-shaped, and the upper end is close to the limiting frame 51 and is located on the upper side of the bottom ring 43 . The extension ring 62 has a λ-shaped cross section and is made of elastic material.

[0060] The plurality of moving blocks 61 are respectively connected to the bottom ends of the plurality of support bars 52 and then connected via the extension ring 62, thereby forming a stable connection structure, ensuring that the scraping assembly 6 will not deform beyond the recovery limit during the deformation process.

[0061] During the storage process, when the storage temperature is too low, the tartaric acid in the fruit wine may be cooled and crystallized to form black residues. When the external temperature drops and the solubility of sugar reaches saturation or supersaturation, turbidity may also occur, and then white flocs and sediments will precipitate. These impurities will accumulate on the bottom wall of the wine storage tank 1 under the action of gravity. In order to prevent impurities from being discharged along with the discharged wine, the impurities are filtered by the filtering component 4. However, after the wine is completely discharged, these impurities need to be cleaned. At this time, the scraping component 6 will clean and scrape away the impurities.

[0062] During the process of wine discharge, the extrusion plate 33 will move downward with the discharge of the wine. As the amount of wine decreases, the extrusion plate 33 will contact the top plate 41, and at the same time drive the top plate 41 to move downward, thereby causing the support bar 52 to move downward, driving multiple moving blocks 61 to move outward. The moving blocks 61 will pull the extension ring 62 to deform during the outward movement. The extension ring 62 and the moving blocks 61 scrape and clean the impurities on the bottom wall of the wine storage tank 1 through the arc-shaped bottom edge, and push the impurities to the outside of the wine storage tank 1. After the wine is completely discharged, the impurities are moved to the outermost edge of the wine storage tank 1, which is convenient for cleaning the impurities.

[0063] After the wine is completely discharged, some wine and impurities will still remain on the bottom wall of the wine storage tank 1. In order to reduce subsequent cleaning and continuously store wine, when the extrusion plate 33 moves upward, the slowly reset support bar 52 will drive the entire scraper assembly 6 to reset. At the same time, since the cross-section of the moving block 61 and the extension ring 62 is λ-shaped, the inner side of the scraper assembly 6 can also scrape and clean the remaining wine and impurities, and transfer this part of the wine and impurities inward for easy cleaning.

[0064] Reference Figure 9-10The wine storage tank 1 is provided with a discharge cavity 12 on one side thereof close to the wine outlet tank 2, the outer side of the wine storage tank 1 is provided with two slag discharge ports 11 connected to the discharge cavity 12 symmetrically, and the inner side of the wine storage tank 1 is provided with two liquid discharge ports connected to the discharge cavity 12 symmetrically;

[0065] The bottom side of the wine storage tank 1 is provided with a slot, which is connected to the slag guide port 11, and is an arc-shaped slot that matches the shape of the side of the moving block 61;

[0066] The bottom surface of the outlet cavity 12 is inclined, and one side close to the liquid outlet is higher than the other side. The bottom end of the wine storage tank 1 is threadedly connected with a collecting ring 9 for collecting impurities inside the outlet cavity 12.

[0067] A sealing assembly 8 is provided inside the outlet chamber, and the sealing assembly 8 includes two control rods 81, two first sealing plates 82 and two second sealing plates 83. The two control rods 81 are symmetrically fixedly installed on the upper end of the outlet chamber 12, and both ends are control ends. The two first sealing plates 82 are respectively fixedly connected to one end of the two control rods 81 close to the outlet chamber 12, and the two second sealing plates 83 are fixedly connected to the control rods 81.

[0068] When the wine is completely discharged and the scraper assembly 6 transfers all the impurities to the inner groove at the edge of the wine tank 1, the scraper assembly 6 will seal the groove to prevent the impurities from being transferred back to the bottom wall of the wine tank 1. At this time, the first sealing plate 82 is driven by the control rod 81 to move, exposing the slag guide port 11, so that the impurities transferred to the edge of the wine tank 1 fall from the slag guide port 11 into the outlet cavity, which makes it convenient to complete the removal of impurities on the bottom wall of the wine tank 1 without opening the wine tank 1. After cleaning, the first sealing plate 82 is resealed and closed.

[0069] During the resetting process of the scraper assembly 6, the remaining wine and impurities will be scraped to the liquid guide port. At this time, the second sealing plate 83 moves under the control of the control rod 81, allowing the wine and impurities to enter the outlet cavity 12 through the liquid guide port. After cleaning, the second sealing plate 83 is re-sealed and closed.

[0070] The wine and impurities that enter the outlet cavity will be transferred to the inside of the collecting ring 9 along the inclined arc of the outlet cavity, which is convenient for cleaning the collected impurities when storing the wine. The collecting ring 9 can collect a large amount of impurities, extend the cleaning cycle, and reduce the use of manpower.

[0071] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
