Description

Technical Field

[0001] This invention relates to the field of separation technology, specifically to a composite filtration and separation device for enzyme-based fruit and vegetable juices. Background Technology

[0002] In recent years, with increasing attention to healthy eating, enzyme-based fruit and vegetable juices have become popular beverages due to their rich nutrition and easy absorption. To meet consumer demand for high-quality enzyme-based fruit and vegetable juices, the production process requires filtration and separation devices to remove impurities and separate solids, ensuring product clarity and taste. Currently, filtration and separation devices on the market mainly include mechanical filtration, centrifugal separation, and membrane filtration, which can achieve preliminary separation and filtration of enzyme-based fruit and vegetable juices to a certain extent. However, existing filtration and separation devices generally have a significant drawback: during use, the filter element is easily clogged by fruit and vegetable residues, fibers, and other impurities, leading to a gradual decrease in filtration efficiency. To maintain normal operation, the device needs to be shut down periodically for cleaning or replacement of the filter element, which not only increases maintenance costs but also reduces production efficiency, failing to meet the needs of continuous, large-scale production.

[0003] For example, traditional mechanical filtration devices typically use filter screens or filter cloths for solid-liquid separation. While simple in structure, these screens are prone to clogging when processing fruit and vegetable juices with high solids content, requiring frequent disassembly and cleaning. Similarly, while membrane filtration technology offers high filtration precision, pectin, proteins, and other substances accumulate on the membrane surface over long-term operation, forming a fouling layer that reduces flux. This necessitates chemical cleaning or high-pressure backwashing to restore performance. These operations are not only time-consuming and labor-intensive but can also damage the filter cartridge, shortening its lifespan. Furthermore, current technologies lack a composite filtration and separation device that can effectively reduce filter cartridge clogging and achieve continuous operation, which to some extent limits the optimization and industrial application of enzyme-based fruit and vegetable juice production processes. Summary of the Invention

[0004] The purpose of this invention is to provide an enzyme fruit and vegetable juice composite filtration and separation device, which solves the technical problems of existing filtration and separation devices that require regular cleaning of the filter element and cannot operate continuously, thereby improving filtration efficiency, reducing maintenance frequency, and realizing continuous production, thus meeting the needs of the modern food processing industry for efficient and stable filtration equipment.

[0005] The present invention solves the above-mentioned technical problems through the following technical solutions, the present invention comprising:

[0006] An elongated shell has a first chamber inside, and a second chamber and a third chamber are sequentially provided on both sides of the first chamber;

[0007] A reciprocating filtration mechanism is disposed inside an elongated housing and is used to filter and separate enzyme fruit and vegetable juices. The reciprocating filtration mechanism includes two winding components disposed in two third chambers respectively. One of the winding components is provided with a first filter belt roll. The filter belt of the first filter belt roll passes through the two second chambers and the first chamber and is wound onto the other winding component to form a second filter belt roll.

[0008] A raw material discharge mechanism is provided in the first chamber, which is used to discharge enzyme fruit and vegetable juice onto the filter belt in the first chamber to achieve the filtration of enzyme fruit and vegetable juice.

[0009] Two cleaning mechanisms are respectively disposed in two second chambers, which are used to remove impurities from the filter belt.

[0010] Preferably, the filter belt has a U-shaped cross-section, with two vertical sections forming vertical filter screens and a horizontal section forming a horizontal filter screen. The two vertical filter screens are connected to the horizontal filter screen via a lower circular flexible strip, and the two vertical filter screens have an upper circular flexible strip on the side away from the lower circular flexible strip.

[0011] Preferably, the raw material discharge mechanism includes a rotating tube rotatably mounted on the inner wall of the first chamber, an inlet pipe rotatably connected to the rotating tube on the elongated shell, and the inlet pipe is connected to an external enzyme fruit and vegetable juice storage device. A flat tube is fixedly connected to the rotating tube, and the end of the flat tube away from the disc has openings on the upper and lower sides. Support rods fixed to the inner wall of the first chamber are provided on both sides of the rotating tube. The rotating tube is connected to the upper round soft strip through a flipping assembly to achieve the orientation flipping of the flat tube.

[0012] Preferably, the flipping assembly includes a first groove formed along the length of the upper circular strip and a disk fixed to the outer circumferential surface of the rotating tube. The first groove is provided with a plurality of evenly distributed first protrusions, and the outer circumferential surface of the disk is uniformly fixed with a plurality of second protrusions, and the second protrusions are engaged with the first protrusions. When the filter belt initially moves, the angle of the flat tube is flipped by the cooperation of the second protrusions and the first protrusions, so that the opening faces the side of the first filter belt roll. When the filter belt moves again, the filter belt vibrates by the cooperation of the second protrusions and the first protrusions.

[0013] Preferably, a vibration assembly is provided between the inner wall of the first chamber and the lower circular flexible strip. The vibration assembly includes a connecting block fixed to the inner wall of the first chamber and a second groove opened along the length direction of the lower circular flexible strip. A plurality of third protrusions are evenly distributed in the second groove, and a fourth protrusion extending between two third protrusions is fixed to the connecting block.

[0014] Preferably, the cleaning mechanism includes an air mold disposed inside the second chamber, the air mold being connected to an external air pump device to remove impurities from the filter belt by high-pressure airflow discharged through the air mold, the second chamber being provided with an impurity screen located below the filter belt, and the side wall of the second chamber being provided with an exhaust vent.

[0015] Preferably, the air mold includes a horizontal air pipe fixed to the inner wall of the second chamber, an air outlet pipe is connected and fixed to the horizontal air pipe, the shape of the air outlet pipe is in contact with the inner wall of the filter belt, an air outlet slit is opened on the outer side of the air outlet pipe, and the horizontal air pipe is connected to an external air pump device.

[0016] Preferably, the filter belt in the first chamber is horizontally arranged, and the filter belts in the two second chambers are inclined upwards to prevent the enzyme fruit and vegetable juice from flowing into the second chambers.

[0017] Preferably, the elongated shell is divided into a first chamber, two second chambers, and two third chambers by four partitions. The partitions are provided with transverse slits, and both ends of the transverse slits are connected to lower circular through holes. Vertical slits are connected to both lower circular through holes, and upper circular through holes are connected to the upper sides of both vertical slits. The transverse filter, lower circular soft strip, vertical filter, and upper circular soft strip pass through the transverse slits, lower circular through holes, vertical slits, and upper circular through holes, respectively.

[0018] Preferably, the winding assembly includes a motor fixed to the outer wall of the elongated housing and a rotating roller detachably disposed on the inner wall of the third chamber, and the output end of the motor is connected to the rotating roller.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. This invention utilizes a reciprocating filtration mechanism, which alternately winds the filter belt with a first filter belt roll and a second filter belt roll, and works in conjunction with a cleaning mechanism to remove impurities from the filter belt in real time. This eliminates the need to stop the machine for cleaning or replacing the filter element, effectively solving the problem of traditional filtration devices requiring regular cleaning due to filter element blockage and being unable to operate continuously. This significantly improves production efficiency and meets the needs of continuous and large-scale production of enzyme fruit and vegetable juices.

[0021] 2. The device adopts a U-shaped filter belt structure, combined with the synergistic effect of the vibration component and the flipping component. The vibration of the filter belt promotes the rapid penetration of enzyme fruit and vegetable juice, reduces the accumulation of impurities on the filter screen, thereby improving filtration efficiency and product quality.

[0022] 3. Two cleaning mechanisms automatically remove impurities from the filter belt through high-pressure airflow or negative pressure system, eliminating the need for frequent manual disassembly and cleaning of the filter element, reducing maintenance costs and operational complexity, and extending the service life of the filter belt.

[0023] 4. The flat tube of the raw material discharge mechanism is rotated at an angle through a flipping component to ensure that the enzyme fruit and vegetable juice is always discharged towards the side of the unused filter belt, which prolongs the residence time of the juice on the filter belt and enhances the filtration effect. At the same time, the U-shaped filter belt and the vertical filter screens on both sides effectively prevent the juice from overflowing and improve the stability and reliability of filtration.

[0039] The above-mentioned and other technical features and advantages of the present invention will be described in more detail below with reference to the accompanying drawings.

[0040] This embodiment provides a technical solution: an enzyme-based fruit and vegetable juice composite filtration and separation device, such as... Figures 1 to 9 As shown, the device includes an elongated housing 1 and a reciprocating filtration mechanism, a raw material discharge mechanism 4, and two cleaning mechanisms 3, all centrally located inside the elongated housing 1. The elongated housing 1 has a first chamber 11, with a second chamber 12 and a third chamber 13 sequentially arranged on both sides of the first chamber 11. The elongated housing 1 is divided into the first chamber 11, two second chambers 12, and two third chambers 13 by four partitions. The elongated housing 1 is equipped with a door for easy maintenance of the equipment inside.

[0041] A reciprocating filtration mechanism is located inside the elongated housing 1. It is used to filter and separate enzyme fruit and vegetable juices. The reciprocating filtration mechanism includes two winding assemblies respectively located in two third chambers 13. The winding assembly includes a motor 21 fixed to the outer wall of the elongated housing 1 and a rotating roller 22 detachably located on the inner wall of the third chamber 13. The output end of the motor 21 is connected to the rotating roller 22, so that the rotating roller 22 can be driven to rotate by running the motor 21. How the output end of the motor 21 is connected to the rotating roller 22 and how it achieves its effect are existing technologies for those skilled in the art and will not be described in detail here. A first filter belt roll 23 is provided on the rotating roller 22 of one of the winding assemblies. The filter belt of the first filter belt roll 23 passes through the two second chambers 12 and the first chamber 11 and is wound onto the other winding assembly to form a second filter belt roll 24. At the same time, the filter belt on one winding assembly is unwound, and the filter belt on the other winding assembly is gradually wound around, so that the filter belt can be pulled back and forth.

[0042] The filter belt has a U-shaped cross-section. The two vertical sections of the U-shaped structure are vertical filter screens 232, and the horizontal section is a horizontal filter screen 231. The two vertical filter screens 232 and the horizontal filter screen 231 are connected by a lower circular flexible strip 233. The side of the two vertical filter screens 232 away from the lower circular flexible strip 233 has an upper circular flexible strip 234. The mesh size of the horizontal filter screen 231 and the vertical filter screen 232 can be set as needed. The vertical filter screens 232 on both sides can prevent the enzyme fruit and vegetable juice from flowing out, thus playing a protective role.

[0043] Furthermore, a horizontal slit 153 is provided on the partition plate. Both ends of the horizontal slit 153 are connected to a lower circular through hole 151. Vertical slits 152 are provided above each of the two lower circular through holes 151. Upper circular through holes 154 are provided above each of the two vertical slits 152. The horizontal filter 231, the lower circular flexible strip 233, the vertical filter 232, and the upper circular flexible strip 234 pass through the horizontal slit 153, the lower circular through hole 151, the vertical slit 152, and the upper circular through hole 154, respectively, and are located on both sides of the partition plate. The horizontal slit 153, lower through hole 151, vertical slit 152, and upper through hole 154 are positioned higher than those on the two inner partitions. This arrangement allows the filter belt in the first chamber 11 to be horizontally positioned, while the filter belts in the two second chambers 12 are inclined upwards. This results in the unfolded filter belt having a structure that is lower in the middle and higher on both sides, preventing the enzyme fruit and vegetable juice from flowing into the second chambers 12. Multiple rotating rollers 14 are rotatably installed in the first chamber 11 to support the filter belt in the first chamber 11 and increase its load-bearing capacity.

[0044] The raw material discharge mechanism 4 is installed in the first chamber 11. It is used to discharge enzyme fruit and vegetable juice onto the filter belt in the first chamber 11. The enzyme fruit and vegetable juice passes through the horizontal filter screen 231 or the vertical filter screen 232 on the filter belt. Impurities will remain on the inside of the horizontal filter screen 231 and the vertical filter screen 232 to achieve the filtration of enzyme fruit and vegetable juice.

[0045] The raw material discharge mechanism 4 includes a rotating tube 41 rotatably mounted on the inner wall of the first chamber 11. An inlet pipe rotatably connected to the rotating tube 41 is mounted on the elongated housing 1 and is connected to an external enzyme fruit and vegetable juice storage device for continuously supplying enzyme fruit and vegetable juice into the rotating tube 41. An outlet pipe is installed at the bottom of the first chamber 11 and is connected to an external storage device to store the filtered enzyme fruit and vegetable juice. A flat tube 44 is connected and fixed to the rotating tube 41, with one end of the flat tube 44 away from the disc 42. It has openings on the upper and lower sides, and baffles 45 are fixed on both sides of the openings to block the discharge of enzyme fruit and vegetable juice. Support rods 46 fixed to the inner wall of the first chamber 11 are provided on both sides of the rotating tube 41. The rotating tube 41 and the upper round soft strip 234 are connected by a flipping assembly to realize the direction flipping of the flat tube 44. When the flat tube 44 is flipped to one side, the flat tube 44 will be placed on the corresponding support rod 46 to ensure that the flat tube 44 can no longer rotate and remains in a horizontal state.

[0046] Furthermore, the flipping assembly includes a first groove 43 formed along the length of the upper circular flexible strip 234 and a disc 42 fixed to the outer circumferential surface of the rotating tube 41. The first groove 43 has a plurality of evenly distributed first protrusions 431, and the outer circumferential surface of the disc 42 has a plurality of evenly fixed second protrusions 421, which mesh with the first protrusions 431. When the filter belt initially moves, the engagement of the second protrusions 421 and the first protrusions 431 pulls the rotating tube 41 to rotate, thereby achieving an angular flip of the flat tube 44, so that the opening faces the side of the first filter belt roll 23, which is the unused side. On the side where the filter belt is transmitted, until the flat tube 44 is placed on the corresponding support rod 46, as the filter belt continues to move, since the upper round soft strip 234 is made of elastic material, it has a certain elasticity. The disc 42 cannot be flipped. That is, with the cooperation of the second protrusion 421 and the first protrusion 431, the upper round soft strip 234 will be squeezed downward. Then, when the second protrusion 421 and the first protrusion 431 are misaligned, the upper round soft strip 234 will bounce upward due to its own elasticity. With the cooperation of multiple first protrusions 431, the filter belt can continuously generate vibration, thereby promoting the filtration efficiency of enzyme fruit and vegetable juice.

[0047] To further enhance the filtration efficiency of the enzyme fruit and vegetable juice, a vibration component 5 is provided between the inner wall of the first chamber 11 and the lower round flexible strip 233. The vibration component 5 includes a connecting block 51 fixed to the inner wall of the first chamber 11 and a second groove 53 opened along the length direction of the lower round flexible strip 233. A plurality of third protrusions 531 are evenly distributed in the second groove 53. A fourth protrusion 52 extending between the two third protrusions 531 is fixed to the connecting block 51. The vibration component 5 and the second protrusion 421 and the first protrusion 431 generate vibrations on the same principle, which is used to drive the two lower round flexible strips 233 to vibrate, and further drive the transverse filter screen 231 to vibrate.

[0048] Two cleaning mechanisms 3 are respectively installed in two second chambers 12, which are used to remove impurities from the filter belt. The cleaning mechanism 3 includes an air mold installed inside the second chamber 12. The air mold is connected to an external air pump. When the air pump is running, the high-pressure airflow generated is discharged through the air mold to impact and break up the impurities on the filter belt. Finally, under the action of the high-pressure airflow, the impurities are discharged through the horizontal filter screen 231 and the vertical filter screen 232 to achieve the removal of impurities. The second chamber 12 is provided with an impurity screen 34 located on the lower side of the filter belt. The impurities will fall onto the impurity screen 34. The impurity screen 34 is pull-out and can be pulled out to clean the impurities on the impurity screen 34. The side wall of the second chamber 12 is provided with an exhaust vent for the high-pressure airflow to be discharged. A dustproof screen 35 is installed in the exhaust vent to prevent external dust from entering the elongated shell 1.

[0049] The air mold includes a horizontal air pipe 31 fixed to the inner wall of the second chamber 12. An air outlet pipe 32 is connected and fixed to the horizontal air pipe 31. The shape of the air outlet pipe 32 fits the inner wall of the filter belt, which is a U-shaped structure. An air outlet slit 33 is opened on the outside of the air outlet pipe 32. The horizontal air pipe 31 is connected to an external air pump device. The high-pressure airflow is discharged through the air outlet slit 33, which can remove impurities on the filter belt.

[0050] In other embodiments, the air mold can also be connected to a negative pressure system. The negative pressure generated will cause impurities to be sucked in through the air outlet 33 and eventually removed. This principle is the same as that of a vacuum cleaner.

[0051] In this embodiment, the two winding components are first operated. The second filter belt roll 24 winds up the filter belt, while the filter belt on the first filter belt roll 23 gradually loosens, allowing the filter belt in the first chamber 11 to move. At this time, with the cooperation of the flipping component, the flat tube 44 flips to one side of the first filter belt roll 23, with the opening of the flat tube 44 close to the first filter belt roll 23. This setting allows the enzyme fruit and vegetable juice to stay on the filter belt in the first chamber 11 for a longer period of time, ensuring the filtration effect of the enzyme fruit and vegetable juice. Then, the operation continues, and the enzyme fruit and vegetable juice is filtered through the moving filter belt. At the same time, the filter belt is cleaned by the cleaning mechanism 3. After cleaning, the filter belt will be wound back to the second filter belt roll 24. When the filter belt on the first filter belt roll 23 is almost used up, the two winding components can be reversed, so that the filter belt on the second filter belt roll 24 loosens and the first filter belt roll 23 winds up the filter belt. This process is repeated.

[0052] The above description is merely a preferred embodiment of the present invention and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, all of which will fall within the protection scope of the present invention.
