[0001] The invention relates to the technical field of lees processing, and in particular to a device for processing lees after fermentation of wine raw materials. Background Art

[0002] Wine lees refer to the solid residue left after the wine raw materials are fermented during the winemaking process. It is an inevitable by-product of the winemaking process and usually contains a large amount of cellulose, hemicellulose, protein, minerals, and incompletely fermented sugars.

[0003] In the prior art, when distiller's grains are recycled, they are first dehydrated. The distiller's grains are inverted in a screw press dehydrator, and the screw shaft pushes the distiller's grains forward along the inside of the screen. The pressure increases step by step as the pitch decreases, and the distiller's grains are dehydrated. Water is squeezed out of the screen, thereby achieving the effect of dehydrating the distiller's grains.

[0004] However, for some wine dregs with higher viscosity, the wine dregs will adhere to the screen, which will cause the mesh of the screen to be blocked, thereby reducing the efficiency of squeezing water from the screen, thereby affecting the efficiency of wine dregs dehydration.

[0036] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making any creative efforts shall fall within the scope of protection of the present invention.

[0037] like Figures 1-10As shown, a device for processing wine lees after fermentation of wine raw materials includes: a feed box 1, a screen 17 and a support plate 7. The side end of the feed box 1 is fixedly connected to a servo motor 2, the side end of the servo motor 2 is fixedly connected to a rotating shaft 19, the outer wall of the rotating shaft 19 is fixedly connected to a spiral blade 3 and passes through the side end of the feed box 1, the side end of the screen 17 is rotatably connected to the feed box 1, and the screen 17 is rotatably connected to a discharge assembly at the end away from the feed box 1. The screen 17 is in a frustum shape and has a plurality of sieve holes 18 opened along the axis. The support plate 7 is arranged on the top of the screen 17, and the bottom end of the support plate 7 is fixedly connected to a plurality of positioning tubes 31 equidistantly along the top edge line of the screen 17. The inner wall of the positioning tube 31 is slidably connected to an elastic plug post 34 The inner cavity of the positioning tube 31 is provided with a supply spring 30, and the upper and lower ends of the supply spring 30 are fixedly connected to the support plate 7 and the plug column 34 respectively. The plug column 34 is slidably connected to the inner wall of the sieve hole 18, and the lees are poured into the feed box 1 from the feed port of the feed box 1. At this time, the servo motor 2 drives the rotating shaft 19 to rotate, and the rotating shaft 19 drives the spiral blade 3 to rotate. The spiral blade 3 rotates along the inner wall of the feed box 1 and the inner wall of the screen 17, and the spiral blade 3 pushes the lees to move. When the lees enter the screen 17, the spacing of the spiral blade 3 begins to decrease. At the same time, the shape of the screen 17 can further squeeze the lees, and the water in the lees flows out from the sieve hole 18, and then the lees are discharged from the discharging assembly.

[0038] Since the wine lees are sticky, in order to prevent the wine lees from adhering to the inner wall of the screen 17 and blocking the screen holes 18, the screen 17 can be driven to rotate by a servo motor of the prior art. The servo motor drives the belt to move, and the belt pulls the screen 17 to rotate. The belt can be installed at the side end of the screen 17. The direction of rotation of the screen 17 is opposite to the direction of rotation of the spiral blade 3. The rotating screen 17 drives the adhered wine lees to move, and the adhered wine lees and the wine lees in the inner cavity of the screen 17 produce friction, thereby removing the adhered wine lees from the inner wall of the screen 17, avoiding the phenomenon that the wine lees adhere to the inner wall of the screen 17 and blocking the screen holes 18, thereby ensuring the efficiency of water flowing out of the screen holes 18.

[0039] When the wine dregs move in the inner cavity of the screen 17, the wine dregs are squeezed more and more. In order to prevent the wine dregs from clogging the screen holes 18, when the screen 17 moves to the bottom of the support plate 7, the plug post 34 slides vertically downward along the inner wall of the positioning tube 31, and the plug post 34 slides along the inner wall of the screen hole 18. When the plug post 34 is inserted into the screen hole 18, the plug post 34 supports the wine dregs blocked in the screen hole 18, and the plug post 34 passes the wine dregs into the inner cavity of the screen 17, thereby preventing the wine dregs from clogging the screen hole 18 and causing water to be unable to be discharged from the screen hole 18.

[0040] When the pin 34 is inserted into the sieve hole 18, the sieve 17 continues to rotate and the pin 34 begins to be pulled out of the sieve hole 18. Since the pin 34 is elastic, the sieve 17 will not be stuck when the pin 34 is inserted into the sieve hole 18. When the pin 34 is completely pulled out from the sieve hole 18, the bottom end of the pin 34 slides along the outer surface of the sieve 17. At the same time, the pin 34 begins to slide upward along the inner wall of the positioning tube 31. The positioning tube 31 has hardness, and the pin 34 is reset from the bent state. When the pin 34 is aligned with the next group of sieve holes 18, the pin 34 is inserted into the sieve hole 18 again, so that the wine lees blocked in the next group of sieve holes 18 can be processed, thereby achieving the effect of continuously processing the wine lees blocked in the sieve holes 18.

[0041] In some specific embodiments, the inner wall of the positioning tube 31 is symmetrically provided with a positioning groove 32 on the axial section, and positioning plates 33 that are slidably connected to the inner wall of the positioning groove 32 are fixed on both sides of the plug post 34. The bottom end of the plug post 34 is provided with a rounded corner, and the positioning plate 33 is abutted against the bottom end of the positioning tube 31. When the plug post 34 slides along the surface of the screen 17, when the plug post 34 is aligned with the screen hole 18, in order to ensure that the plug post 34 can be instantly inserted into the screen hole 18, the supply spring 30 provided in the inner cavity of the positioning tube 31 is in a compressed state, and the elastic tension provided by the supply spring 30 is transmitted to the plug post 34. When the plug post 34 is aligned with the screen hole 18, the plug post 34 can be directly inserted into the screen hole 18, thereby processing the wine lees blocked in the screen hole 18. Among them, when the positioning plate 33 and the positioning tube 31 abut, it can provide a positioning function for the plug post 34 to prevent the plug post 34 from slipping out of the positioning tube 31.

[0042] When the pin 34 slides along the surface of the screen 17, in order to avoid the bottom end of the pin 34 causing scratches on the surface of the screen 17, the rounded corners at the bottom end of the pin 34 can prevent the edge of the pin 34 from scratching the screen 17. At the same time, when the pin 34 is pulled out of the screen hole 18, the edge of the pin 34 causes scratches on the inner wall of the screen hole 18. When the bottom end of the pin 34 contacts the lees, the rounded corner shape reduces the contact area between the lees and the bottom end of the pin 34, which can prevent the lees from adhering to the bottom end of the pin 34.

[0043] In some specific embodiments, the side end of the support plate 7 is fixedly connected to the air distribution pipe 6 through the connecting plate 20, and the bottom end of the air distribution pipe 6 is fixedly connected to a plurality of nozzles 26 at equal distances along the top edge line of the feed box 1. The side end of the air distribution pipe 6 is fixedly connected to the top of the discharge assembly through the support frame 8, and the air distribution pipe 6 is fixedly connected to the air intake assembly at the end away from the support frame 8. The inner cavity of the air distribution pipe 6 is communicated with the nozzle 26 and the air intake assembly respectively, and the air intake assembly is fixedly connected to the top of the feed box 1. The rotating shaft 19 passes through the discharge assembly, and the discharge barrel 9 provides support for the air distribution pipe 6 through the support frame 8. The side end of the air distribution pipe 6 is connected to the top of the discharge assembly. The connecting plate 20 provides support for the support plate 7. When water flows out from the sieve hole 18 opened at the top of the screen 17, the plug column 34 slides along the surface of the screen 17, and the plug column 34 can scrape the water. In order to prevent water from entering the screen 17 again from the sieve hole 18, the filtered air is introduced into the air intake component through the blower of the existing technology. The wind enters the inner cavity of the air distribution pipe 6 through the air intake component, and the wind is ejected from the nozzle 26. The wind is sprayed vertically downward on the surface of the top of the screen 17. The wind can clean the water on the surface of the screen 17 and prevent water from entering the screen 17 from the sieve hole 18 again.

[0044] In order to further improve the efficiency of removing water from the lees, the wind can be heated before entering the air intake component. When the wind is sprayed on the screen 17 with heat, the heat can heat the screen 17. At the same time, the heat can enter the screen 17 from the screen hole 18, so that the heat can heat the lees and increase the temperature, thereby further improving the efficiency of removing water from the lees.

[0045] In some specific embodiments, the air intake assembly includes: an air intake pipe 4 and a connector 5, the air intake pipe 4 is fixedly connected to the side end of the air distribution pipe 6, the connector 5 is fixedly connected to the side end of the air intake pipe 4, and the connector 5 is connected to the inner cavity of the air intake pipe 4. When the wind starts to enter the air intake assembly, the wind enters the air intake pipe 4 through the connector 5, and then the wind flows out of the air intake pipe 4 into the inner cavity of the air distribution pipe 6. The outer surface of the connector 5 is provided with a threaded line, and the wind can be transported through the conduit, and the conduit can be threadedly connected and installed on the connector 5.

[0046] In some specific embodiments, the discharging assembly includes: a discharging barrel 9 and a discharging pipe 16. A discharging port 22 is provided at the bottom of the discharging barrel 9. The bottom end of the discharging barrel 9 is fixedly connected to the discharging pipe 16. A blocking plate 23 is slidably connected to the inner wall of the discharging barrel 9. The top of the discharging barrel 9 is fixedly connected to the support frame 8. The discharging pipe 16 is connected to the discharging port 22. The rotating shaft 19 passes through the discharging barrel 9. When the wine lees is pushed into the discharging barrel 9 by the spiral blade 3, the wine lees is pushed by the subsequent wine lees and moves along the inner wall of the discharging barrel 9. In order to improve the squeezing effect on the wine lees, the wine lees are first squeezed with the blocking plate 23, and then push the blocking plate 23 to move. When the wine lees move to the discharging port 22, the wine lees starts to fall from the discharging port 22, and then enters the discharging pipe 16 for discharge. The discharging pipe 16 provides support and fixation for the discharging barrel 9.

[0047] In some specific embodiments, the blocking plate 23 is slidably connected to the outer wall of the rotating shaft 19, and a limiting tube 25 slidably connected to the outer wall of the rotating shaft 19 is fixed to the end of the blocking plate 23 away from the discharge barrel 9. The blocking plate 23 is fixedly connected to the driving assembly through the driving spring 15. When the blocking plate 23 slides along the inner wall of the discharge barrel 9, the blocking plate 23 slides along the outer wall of the rotating shaft 19. At the same time, the blocking plate 23 slides along the outer wall of the rotating shaft 19 with the limiting tube 25. The position of the blocking plate 23 in the discharge barrel 9 can be controlled by the driving assembly. The support provided by the rotating shaft 19 for the limiting tube 25 is transmitted to the blocking plate 23, thereby ensuring the stability of the blocking plate 23 on the rotating shaft 19, avoiding the phenomenon that the rotating shaft 19 is squeezed by the lees and overturning, and ensuring the balance of the blocking effect provided by the blocking plate 23 for the lees.

[0048] The baffle plate 23 is first located at the side end of the spiral blade 3. When the wine lees move to the side end of the spiral blade 3, in the prior art, the wine lees will initially fall directly from between the baffle plate 23 and the discharge barrel 9, which causes the wine lees that are first dehydrated to obtain insufficient extrusion pressure at the beginning. When the wine lees accumulate between the baffle plate 23 and the discharge barrel 9, the wine lees can be fully blocked by the baffle plate 23, thereby ensuring that the extrusion pressure obtained by the wine lees is more sufficient. Therefore, the baffle plate 23 first blocks the discharge port 22, and at the same time, provides sufficient blocking for the wine lees that are being dehydrated. When the baffle plate 23 slides along the inner wall of the discharge barrel 9, the baffle plate 23 releases the blocking effect on the discharge port 22, so that the wine lees are discharged from the discharge port 22.

[0049] In some specific embodiments, the driving assembly includes: a slider 11, a driver 12, a driving seat 13 and a driving tube 14. The side end of the driving seat 13 is fixedly connected to the driving spring 15. The two sides of the driving seat 13 are slidingly connected to the guide rails 10 through the slider 11. The two ends of the driver 12 are respectively fixedly connected to the guide rails 10. The driving tube 14 is slidingly connected to the outer wall of the rotating shaft 19, and the side end is fixedly connected to the driving seat 13. The driving spring 15 is respectively mounted on the driving tube 14 and the limiting tube 25. When the blocking plate 23 needs to move to the side end of the spiral leaf 3, the driver 12 provides driving action for the slider 11. The side end of the slider 11 slides along the sliding groove opened in the guide rail 10. The slider 11 moves with the driving seat 13, and the driving seat 13 moves with the driving tube 14 and the driving spring 15. The driving spring 15 pushes the blocking plate 23 to move, thereby moving the blocking plate 23 to the side end of the spiral leaf 3.

[0050] The side end of the rotating shaft 19 is inserted into the driving tube 14, and the sliding groove opened in the guide rail 10 is connected with the side end of the slider 11, so that the guide rail 10 provides support for the slider 11, the slider 11 provides support for both ends of the driving seat 13, the driving seat 13 provides support for the driving tube 14, and the driving tube 14 provides support for the side end of the rotating shaft 19, thereby ensuring the overall stability of the rotating shaft 19, and then ensuring the stability of the rotating shaft 19 driving the spiral blade 3 to rotate.

[0051] When the wine lees push the blocking plate 23 to move, the driving spring 15 begins to compress. The elastic tension provided by the driving spring 15 can provide resistance for the blocking plate 23, so that the blocking plate 23 can provide resistance to the wine lees. When the blocking plate 23 stops sliding in the discharge barrel 9, the wine lees can be continuously discharged from the discharge port 22. At the same time, the blocking plate 23 can always provide a blocking effect for the wine lees.

[0052] In some specific embodiments, the blocking plate 23 is fixedly connected to a plurality of sensors 24 at one end away from the discharge barrel 9. When the blocking plate 23 provides a blocking effect for the lees, the sensor 24 can detect the force between the lees and the blocking plate 23, thereby detecting the squeezing effect of the blocking plate 23 on the lees. In order to avoid the phenomenon that the blocking plate 23 exerts a large force on the lees, which causes damage to the lees, and at the same time, the outflow of sugar in the lees causes the viscosity of the lees to increase, the position of the blocking plate 23 in the discharge barrel 9 can be adjusted according to the data detected by the sensor 24. When the squeezing force provided by the blocking plate 23 increases, the driving seat 13 moves with the driving spring 15, and the driving spring 15 reduces the elastic supporting force on the blocking plate 23. The blocking plate 23 is squeezed by the lees and continues to slide along the inner wall of the discharge barrel 9. The blocking plate 23 reduces the area blocked by the discharge port 22, and more lees can be discharged from the discharge port 22. At this time, the blocking plate 23 stops moving, providing appropriate blocking for the lees, ensuring that the lees are subjected to appropriate squeezing force, and thus reaching a new balance.

[0053] In some specific embodiments, a rotating groove 29 is opened at the side end of the feed box 1, and a rotating plate 27 in the shape of a circular ring is fixedly connected to the side end of the screen 17. The rotating plate 27 is clamped and connected to the inner wall of the rotating groove 29, and the rotating plate 27 is rotatably connected to the inner wall of the rotating groove 29. A number of groups of balls 28 are provided inside the rotating groove 29, and the upper and lower ends of the balls 28 are respectively rollingly connected to the rotating groove 29 and the rotating plate 27. When the screen 17 rotates, the screen 17 rotates along the inner wall of the rotating groove 29 with the rotating plate 27. The clamping connection between the rotating plate 27 and the inner wall of the rotating groove 29 provides a limiting support for the side end of the screen 17 to prevent the screen 17 from shaking.

[0054] When the rotating plate 27 rotates along the inner wall of the rotating groove 29 , the rotating plate 27 slides along the ball bearings 28 . At this time, the ball bearings 28 roll in the rotating groove 29 , and the ball bearings 28 reduce the friction force of the rotating plate 27 sliding on the inner wall of the rotating groove 29 .

[0055] In some specific embodiments, a plurality of guide grooves 21 are provided on the outer wall of the screen 17 at equal intervals along the length direction. The cross-section of the guide grooves 21 is arc-shaped and is connected to the screen holes 18. When the plug post 34 slides along the surface of the screen 17, in order to ensure that the plug post 34 can be aligned with the next group of screen holes 18, when the plug post 34 is pulled out from the screen hole 18, the bottom end of the plug post 34 slides along the inner wall of the guide groove 21. The guide groove 21 provides a limiting guide for the sliding of the plug post 34, thereby ensuring that the plug post 34 can be aligned with the next group of screen holes 18.

[0056] The above describes several embodiments of the present invention in detail, but the embodiments of the present invention are not limited to these and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
