Description

Technical Field

[0001] This invention relates to the field of fruit wine filtration technology, and more specifically to ceramic membrane filtration equipment used in fruit wine processing. Background Technology

[0002] In the production of fruit wine, after fruit fermentation, the fermented product needs to be filtered and clarified to remove fruit pulp and obtain the original fruit wine liquid. Therefore, filtration is a crucial step in fruit wine production, as it must preserve the flavor compounds while ensuring the wine's taste and quality. However, traditional filtration devices often use membranes or screens. The design of membrane filters can lead to excessive levels of plasticizers in the alcohol, thus affecting the filtration effect.

[0003] To address the aforementioned issues, Chinese Patent Publication No. CN220940003U discloses a filtration and purification device for wine preparation, comprising a tank and a filter membrane. The tank has an open top structure with a top cover. The filter membrane is detachably installed below the top cover via a connecting assembly, and the filter membrane is made of flat ceramic membrane. Compared to traditional polymer separation membrane materials, the flat ceramic membrane in this device exhibits superior chemical stability, resistance to acids, alkalis, and organic solvents, effectively preventing excessive levels of plasticizers in the alcohol and thus significantly improving the filtration effect of fruit wine.

[0004] The above-mentioned device has the following problems in actual use: During the filtration of fruit wine, fruit residue will be deposited and accumulate on the ceramic membrane, which will significantly affect the normal operation of the ceramic membrane and may even block the ceramic membrane, thereby weakening the filtration effect of the ceramic membrane and reducing filtration efficiency and quality. Summary of the Invention

[0005] This invention provides a ceramic membrane filtration device for fruit wine processing to solve the problem that existing filtration devices cannot disperse accumulated fruit pomace during ceramic membrane filtration.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a ceramic membrane filtration device for fruit wine processing, comprising a top-opening settling cylinder, a bottom-opening filter cylinder, and a filtration mechanism disposed within the filter cylinder; the filter cylinder is connected to the settling cylinder, and an inlet is provided on the filter cylinder; the filtration mechanism comprises an annular hollow block, a ceramic filter membrane, a fixing block, a rotating shaft, a bottom block, a stirring element symmetrically arranged on the bottom block, a fixing hole on the filter cylinder, a power component for driving the rotating shaft to rotate, and a drive component for driving the annular hollow block to rotate; the annular hollow block is rotatably connected to the filter cylinder; the ceramic filter membrane is fixedly connected to the annular hollow block; the fixing block is fixedly connected to the fixing hole; the rotating shaft is rotatably connected to the fixing block; the bottom block is fixedly connected to the rotating shaft and is in contact with the ceramic filter membrane; the stirring element is fixedly connected to the bottom block.

[0007] The principles and advantages of this scheme are: The fruit wine to be filtered is introduced into the filter cylinder through the inlet, and then flows through the ceramic filter membrane into the settling cylinder. Filtering through the ceramic membrane effectively removes large molecular impurities such as proteins, pectin, and plant fibers, ensuring the wine remains clear even after long-term storage. Simultaneously, filtration through the ceramic membrane preserves heat-sensitive vitamins, amino acids, polyphenols, and other nutrients and natural flavors, avoiding the loss of taste caused by high temperatures or chemical processing.

[0008] Because the ceramic filter membrane can rotate with the annular hollow block, the fruit wine can form a dynamic flow during the filtration process, reducing concentration polarization and preventing excessive accumulation of fruit residue on the ceramic filter membrane, thereby improving filtration efficiency.

[0009] During the rotation of the ceramic filter membrane, the bottom block helps to disperse the fruit pomace deposited on the ceramic filter membrane, thereby reducing the amount of fruit pomace deposited and improving the cleanliness of the ceramic filter membrane. This results in more uniform flow of fruit wine and improved filtration consistency.

[0010] Because the bottom block can rotate relative to the ceramic filter membrane, it increases the force of the bottom block and expands the range of action of the bottom block, enabling the bottom block to more efficiently disperse the fruit residue deposited on the ceramic filter membrane, thus enhancing the effect of the bottom block.

[0011] The stirring element is designed to keep the solid particles in the fruit wine suspended during the rotation of the bottom block, preventing them from settling and accumulating in static or low-flow-rate areas, thereby reducing the risk of local blockage, ensuring uniform fruit wine concentration, and guaranteeing continuous and stable filtration operation.

[0012] Furthermore, the fixed block is a fixed tube, the rotating shaft is an auxiliary tube, and the auxiliary tube is connected to the fixed tube; it also includes an auxiliary component; the auxiliary component includes a cavity opened in the bottom block and a number of bottom holes opened at equal intervals along the length of the cavity; the auxiliary tube is connected to the cavity.

[0013] After the fruit wine is filtered, all the fruit wine in the settling tank is drained. After the fruit wine is drained, the liquid guide tube is connected to the fixed tube, so that the cleaning solution can be discharged through the auxiliary tube and the bottom hole. After being discharged through the bottom hole, the cleaning solution can be injected directly into the pores of the ceramic filter membrane in a directional flow, thereby effectively dispersing and peeling off colloidal deposits such as fruit pomace, polysaccharides, and proteins embedded in the membrane pores.

[0014] Furthermore, by primarily using water spray cleaning and secondarily using a bottom block, the contact pressure between the bottom block and the membrane surface is significantly reduced, preventing micro-cracks from forming on the ceramic filter membrane due to hard friction, thus extending the service life of the ceramic filter membrane.

[0015] Multiple bottom holes are equidistantly arranged along the length of the chamber and, in conjunction with the circumferential movement of the ceramic filter membrane, form a continuously covering "water curtain" cleaning zone. This eliminates the cleaning blind spots caused by traditional single-point cleaning, ensuring consistent regeneration of all areas of the ceramic filter membrane, thereby improving the stability of filtration quality.

[0016] Furthermore, it also includes an auxiliary part disposed within the chamber; the auxiliary part includes an auxiliary block, a plurality of fillers equidistantly disposed along the length direction of the auxiliary block, and a drive unit for driving the auxiliary block to perform intermittent reciprocating motion along the length direction of the chamber; the auxiliary block is slidably connected to the chamber; the fillers are located between two adjacent bottom holes, the fillers are fixedly connected to the auxiliary block, and the fillers can seal the bottom holes.

[0017] During the movement of the auxiliary block, the packing material moves synchronously. During the movement of the packing material, it can periodically open and close the bottom orifice, causing the originally continuous cleaning fluid to form a high-frequency pulse jet. This pulse effect can generate instantaneous impact force, which can effectively break up colloidal deposits such as fruit pomace, polysaccharides, and proteins embedded in the membrane pores, thus significantly improving the unblocking efficiency within the membrane pores.

[0018] Furthermore, the filler includes several unclogging brushes; one end of the unclogging brush, away from the auxiliary block, extends into the bottom hole and abuts against the ceramic filter membrane.

[0019] The purpose of the cleaning brush is to extend into the membrane pores through its elasticity. With the coordinated movement of the ceramic filter membrane's circumferential motion and the rotation of the bottom block, the cleaning brush can perform high-frequency micro-scraping treatment on the pore walls, directly loosening the adhesion of colloidal deposits such as fruit pomace, polysaccharides, and proteins. This achieves the cleaning of the membrane pores and further enhances the filtration effect of the ceramic filter membrane.

[0020] At the same time, the unclogging brush can reciprocate within two adjacent bottom holes, thereby clearing the colloidal deposits such as fruit residue, polysaccharides, and proteins that clog the bottom holes. This allows the cleaning fluid to flow efficiently through the bottom holes, further enhancing their effectiveness.

[0021] Furthermore, it also includes a flow regulating section; the flow regulating section includes a connecting block, an inner tube with an opening at the bottom, a flow regulating pipe with an opening at the bottom, a through hole on the auxiliary tube, and a flow regulating hole on the chamber; the two ends of the connecting block are fixedly connected to the auxiliary block and the flow regulating pipe respectively; the inner tube is fixedly connected to the through hole; the flow regulating pipe is slidably connected to the inner tube; both the inner tube and the flow regulating pipe are connected to the flow regulating hole.

[0022] The inner tube and the flow regulating tube are designed to increase the flow rate of the cleaning fluid into the chamber through the auxiliary tube, thereby enabling the cleaning fluid to be discharged stably and efficiently through the bottom hole, thus enhancing the discharge effect of the cleaning fluid.

[0023] Because the flow regulating pipe can reciprocate along the length of the inner pipe, the orifice of the cleaning fluid flowing into the inlet chamber expands alternately from left to right, which enables the cleaning fluid to flow into the left and right sides of the inlet chamber in a directional manner, thereby improving the uniformity of the cleaning fluid flowing into the inlet chamber and ensuring the quality of the cleaning fluid discharged from the left and right sides of the chamber.

[0024] Furthermore, it also includes a linkage assembly; the linkage part includes a linkage box with a top opening, linkage parts symmetrically arranged inside the linkage box, and linkage holes opened on the fixed pipe; the linkage box is fixedly connected to the fixed pipe, and the linkage box communicates with the linkage holes; the linkage part includes a linkage shaft, blades, side holes opened on the linkage box, and a motion unit for driving the linkage shaft to rotate; the linkage shaft is rotatably connected to the linkage box; the blades are fixedly connected to the linkage shaft, and the blades face the side holes.

[0025] During the circumferential movement of the ceramic filter membrane, the cleaning solution is discharged through the side holes, thus forming a high-level flushing of the ceramic filter membrane. This, combined with the low-level directional cleaning of the membrane pores through the bottom holes, ensures that the entire ceramic filter membrane is thoroughly cleaned during rotation, thereby avoiding insufficient cleaning in certain areas or dead zones.

[0026] During the discharge of the cleaning fluid through the side holes, the blades drive the flow rate of the cleaning fluid, thereby increasing the cleaning force and enabling the cleaning fluid to efficiently and completely flush the ceramic filter membrane from a high position, thus enhancing the effect of the side holes.

[0027] Furthermore, the linkage also includes a linkage unit; the linkage unit includes a bottom shaft, a torsion spring, a linkage tube, and several spray holes equidistantly opened on the linkage tube along the axial direction of the linkage tube; the bottom shaft is rotatably connected to the linkage box, and the two ends of the torsion spring are respectively connected to the bottom shaft and the linkage box; the linkage tube is fixedly connected to the bottom shaft, and the linkage tube can swing in the side hole; the stirring component includes a first stirring block and a second stirring block; the length of the first stirring block is greater than the length of the second stirring block, and the linkage tube is located on the movement trajectory of the first stirring block.

[0028] During the discharge of cleaning fluid through the side holes, the intermittent oscillation of the linkage pipe causes the cleaning fluid spray trajectory to sweep in a fan shape, thereby expanding the coverage area of ​​the linkage pipe and ensuring that all areas of the ceramic filter plate are evenly rinsed, avoiding local pollution accumulation, which further improves the discharge efficiency and quality of cleaning fluid through the side holes.

[0029] Furthermore, the power assembly includes a power shaft, a first bevel gear, a second bevel gear, and a power unit for driving the power shaft to rotate; the power shaft is rotatably connected to a fixed pipe; the first bevel gear is fixedly connected to the power shaft, the second bevel gear is fixedly connected to an auxiliary pipe, and the first bevel gear meshes with the second bevel gear.

[0030] During the rotation of the power shaft, the power shaft drives the auxiliary pipe to rotate through the meshing of the first bevel gear and the second bevel gear.

[0031] Furthermore, the drive unit includes a side block, a first wedge, and drive components located at both ends of the auxiliary block; the side block is fixedly connected to the fixed tube; the first wedge is fixedly connected to the side block; the drive component includes a second wedge and a side hole opened in the chamber; the second wedge is fixedly connected to the auxiliary block, and the second wedge can slide in and out of the side hole; the first wedge is located on the movement trajectory of the second wedge.

[0032] During the rotation of the bottom block, the two second wedges alternately abut against the first wedge, thereby enabling the two wedges to drive the auxiliary block to perform intermittent reciprocating motion along the length of the chamber.

[0033] Furthermore, a third bevel gear is fixedly connected to the auxiliary tube; the motion unit is a fourth bevel gear; the fourth bevel gear is fixedly connected to the linkage shaft, and the third bevel gear meshes with the fourth bevel gear.

[0034] During the rotation of the auxiliary tube, the meshing of the third and fourth bevel gears drives the linkage shaft to rotate. Attached Figure Description

[0056] Specific implementation process: The fruit wine to be filtered is introduced into the filter cylinder 2 through the inlet pipe 3, and then flows into the settling cylinder 1 through the ceramic filter membrane 5. After being filtered through the ceramic filter membrane 5, the fruit wine can effectively retain large molecular impurities such as proteins, pectin, and plant fibers, ensuring that the fruit wine remains clear even after long-term storage. At the same time, filtration through the ceramic filter membrane 5 can completely preserve the vitamins, amino acids, polyphenols, and other nutrients and natural flavors in the fruit wine, avoiding the loss of taste caused by high temperature or chemical treatment.

[0057] During filtration by the ceramic filter membrane 5, the motor 9 is started, and the output shaft of the motor 9 drives the drive shaft 10 to rotate. During the rotation of the drive shaft 10, the drive shaft 10 drives the annular hollow block 4 to rotate through the meshing of the gear 11 and the annular rack 12. During the rotation of the annular hollow block 4, the ceramic filter membrane 5 moves synchronously.

[0058] Since the ceramic filter membrane 5 can rotate with the annular hollow block 4, the fruit wine can form a dynamic flow during the filtration process, reducing concentration polarization and preventing excessive accumulation of fruit residue on the ceramic filter membrane 5, thereby improving filtration efficiency.

[0059] During the rotation of drive shaft 10, drive shaft 10 drives power shaft 32 to rotate through the meshing of fifth bevel gear 40 and sixth bevel gear 41. During the rotation of power shaft 32, power shaft 32 drives auxiliary tube to rotate through the meshing of first bevel gear 33 and second bevel gear 34. During the rotation of auxiliary tube, bottom block 7 rotates synchronously.

[0060] During the rotation of the ceramic filter membrane 5, the bottom block 7 can diffuse the fruit residue deposited on the ceramic filter membrane 5, thereby reducing the amount of fruit residue deposited and improving the cleanliness of the ceramic filter membrane 5, thus making the fruit wine flow more evenly and improving the consistency of filtration.

[0061] Since the bottom block 7 can rotate relative to the ceramic filter membrane 5, the force of the bottom block 7 is increased and the range of action of the bottom block 7 is expanded, enabling the bottom block 7 to more efficiently disperse the fruit residue deposited on the ceramic filter membrane 5, thus enhancing the effect of the bottom block 7.

[0062] During the rotation of the bottom block 7, the first stirring block 30 and the second stirring block 31 are set to keep the solid particles in the fruit wine in a suspended state, avoid them from settling and accumulating in static or low flow rate areas, thereby reducing the risk of local blockage, ensuring uniform fruit wine concentration, and ensuring continuous and stable operation of filtration.

[0063] After the fruit wine is filtered, all the fruit wine in the settling tank 1 is drained. After the fruit wine is drained, the liquid guide tube is connected to the fixed tube, and the pressurized cleaning solution is introduced into the liquid guide tube, so that the cleaning solution can be discharged through the auxiliary tube and the bottom hole 14. After the cleaning solution is discharged through the bottom hole 14, it can be injected directly into the membrane pores of the ceramic filter membrane 5 in a directional flow manner, thereby effectively dispersing and peeling off colloidal deposits such as fruit pomace, polysaccharides, and proteins embedded in the membrane pores.

[0064] Furthermore, by primarily using water spray cleaning and secondarily using the bottom block 7, the contact pressure between the bottom block 7 and the membrane surface is significantly reduced, preventing micro-cracks from forming on the ceramic filter membrane 5 due to hard friction, thus extending the service life of the ceramic filter membrane 5.

[0065] Multiple bottom holes 14 are equidistantly arranged along the length of the chamber and move in conjunction with the circumferential movement of the ceramic filter membrane 5 to form a continuously covering "water curtain" cleaning zone, eliminating the cleaning blind spots caused by traditional single-point cleaning, ensuring the regeneration consistency of each area of ​​the ceramic filter membrane 5, and thus improving the stability of filtration quality.

[0066] During the rotation of the two second wedges 37 with the bottom block 7, the two second wedges 37 alternately abut against the first wedge 36, thereby enabling the two wedges to drive the auxiliary block 16 to perform intermittent reciprocating motion along the length of the chamber.

[0067] During the movement of the auxiliary block 16, the unblocking brush 17 moves synchronously. During the movement of the unblocking brush 17, it can periodically open and close the bottom hole 14, so that the originally continuous cleaning fluid will form a high-frequency pulse jet. This pulse effect can generate instantaneous impact force, which can effectively break up colloidal deposits such as fruit pomace, polysaccharides, and proteins embedded in the membrane pores, thus significantly improving the unblocking efficiency of the membrane pores.

[0068] The purpose of the unclogging brush 17 is to extend into the membrane pores through its elasticity. With the coordinated movement of the ceramic filter membrane 5 in the circumferential direction and the rotation of the bottom block 7, the unclogging brush 17 can perform high-frequency micro-scraping treatment on the pore walls of the membrane pores, directly loosening the adhesion of colloidal deposits such as fruit pomace, polysaccharides, and proteins, thereby achieving the cleaning treatment inside the membrane pores and further enhancing the filtration effect of the ceramic filter membrane 5.

[0069] At the same time, the unblocking brush 17 can reciprocate within the two adjacent bottom holes 14, thereby unblocking the colloidal deposits such as fruit residue, polysaccharides, and proteins that clog the bottom holes 14, thus promoting the efficient flow of the cleaning fluid through the bottom holes 14, which further enhances the effect of the bottom holes 14.

[0070] The inner tube 19 and the flow regulating tube 20 are designed to increase the flow rate of the cleaning fluid into the inlet chamber through the auxiliary tube, thereby enabling the cleaning fluid to be discharged stably and efficiently through the bottom hole 14, thus enhancing the discharge effect of the cleaning fluid.

[0071] During the movement of the auxiliary block 16, the auxiliary block 16 drives the flow regulating pipe 20 to move synchronously through the connecting block 18, thereby enabling the flow regulating pipe 20 to reciprocate along the length of the inner pipe 19. Therefore, under the action of the reciprocating motion of the flow regulating pipe 20, the aperture of the cleaning fluid flowing into the inlet chamber is alternately expanded from left to right, which promotes the directional flow of the cleaning fluid into the left and right sides of the inlet chamber, thereby improving the uniformity of the cleaning fluid flowing into the inlet chamber, that is, ensuring the quality of the cleaning fluid discharged from the left and right sides of the chamber.

[0072] During the circumferential movement of the ceramic filter membrane 5, the cleaning fluid flows into the linkage box 22 through the linkage hole 23 and is finally discharged through the side hole. This forms a high-level rinsing of the ceramic filter membrane 5, and in conjunction with the low-level directional cleaning of the membrane pores through the bottom hole 14, thereby ensuring that the entire ceramic filter membrane 5 is fully cleaned during the rotation process, thus avoiding insufficient cleaning in certain areas or dead corners.

[0073] During the rotation of the auxiliary tube, the meshing of the third bevel gear 38 drives the linkage shaft 24 to rotate. During the rotation of the linkage shaft 24, the blades 25 rotate synchronously. Therefore, during the discharge of the cleaning fluid through the side holes, the drive of the blades 25 accelerates the flow rate of the cleaning fluid and increases its cleaning force, thereby enabling the cleaning fluid to efficiently and completely rinse the ceramic filter membrane 5 from a high position, thus enhancing the effect of the side holes.

[0074] During the movement of the first stirring block 30, the linkage pipe 28, in coordination with the first stirring block 30, the bottom shaft 26, and the torsion spring 27, can intermittently reciprocate. Therefore, during the discharge of cleaning fluid through the side holes, the intermittent oscillation of the linkage pipe 28 causes the cleaning fluid spray trajectory to sweep in a fan shape, thereby expanding the coverage area of ​​the linkage pipe 28, ensuring that all areas of the ceramic filter plate are evenly rinsed, avoiding local contamination accumulation, and thus further improving the discharge efficiency and quality of the cleaning fluid through the side holes.

[0075] In summary, during fruit wine filtration, the filtration efficiency is comprehensively improved by reducing the probability of clogging of the ceramic filter membrane 5 and accelerating the fruit wine filtration process. Furthermore, after filtration, the ceramic filter plate is thoroughly cleaned by introducing cleaning fluid into the fixed tube, thus improving both the filtration efficiency and quality of the ceramic filter plate.
