[0010] Preferably, the cleaning box has round holes on both sides, and the two round holes correspond one-to-one with the two pull cords; The two sliding pins are symmetrically arranged about the axis of the right shaft.

[0011] A method of using an allulose inversion reaction filtration device includes the following steps: S1. When in use, after the reaction liquid inside the reaction tank enters the filter cartridge, the reaction liquid falls from the filter tank position to the top position of the filter belt between the two synchronous belts for filtration. At this time, the start motor drives the corresponding shaft to rotate clockwise. Under the transmission of the synchronous pulley, the two synchronous belts drive the filter belt to rotate continuously and switch the filtration position. S2. During the synchronous rotation of the right shaft, the right shaft drives the incomplete gear to rotate, causing the incomplete gear to mesh with the adjacent adjusting gear in stages. At this time, the adjusting gear drives the two U-shaped hinge blocks to rotate synchronously, causing the two U-shaped hinge blocks to deflect in different directions. With the cooperation of the hinge rod, the two piston rods also move in different directions and slide inside the corresponding piston cylinder. At this time, the upper piston rod moves to the left and delivers the gas inside the corresponding piston cylinder to the exhaust pipe and spring hose position, so that the gas is discharged from the end position of the arc-shaped air blowing hood. Then the gas blows out from the back of the filter belt to the filter surface position, blowing the foreign objects at the filter surface position of the filter belt into the interior of the cleaning box for collection. Since the two piston rods move in opposite directions, the two piston cylinders deliver gas into the arc-shaped air blowing hood in a staggered manner, continuously cleaning the surface of the filter belt. S3. Simultaneously, during the movement of the piston rod, the U-shaped adjustment bracket at the end of the piston rod cooperates with the adjustment pin, causing the adjustment pin to slide inside the adjustment groove on the surface of the corresponding adjustment block. As the two piston rods move back and forth in a staggered manner, the two piston rods, through the cooperation of the U-shaped adjustment bracket and the adjustment block, swing back and forth on the surface of the right shaft with the arc-shaped air blowing cover, increasing the cleaning range of the filter belt. S4. At the same time, the rotation of the right shaft will cause the turntable to rotate synchronously. During the sliding process of the sliding pin on the turntable surface and the waist-shaped sliding plate, the waist-shaped sliding plate and the corresponding telescopic rod will move horizontally back and forth on the side wall of the turntable. Due to the misalignment of the two sliding pins, the two waist-shaped sliding plates will move back and forth inside the cleaning box through the pull rope with the squeezing plate, pushing the foreign objects collected inside the cleaning box to the corresponding pad side wall position. At this time, the foreign objects will squeeze out the internal liquid during the compression process and be discharged from the drain groove position. As the squeezing plate continues to move, it pushes the pad to move horizontally inside the groove, pushing the compressed foreign objects to the upper position of the discharge groove, so that the foreign objects can be automatically discharged from the discharge groove position for collection.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: In this invention, the filter belt, filter cylinder, and cleaning mechanism are used in combination to enable the filter belt to move with the synchronous belt and continuously change the filtration position. At the same time, the filter belt surface is continuously cleaned with the help of the cleaning mechanism during operation, ensuring that the filtration device maintains a good filtration effect at all times during equipment operation.

[0013] In this invention, through the coordinated use of components such as the cleaning mechanism, shaft, and filter belt, when the cleaning mechanism cleans the corresponding filter belt surface, the piston rod reciprocates and moves in conjunction with the U-shaped adjusting frame and adjusting block, causing the arc-shaped air blowing hood to swing back and forth on the surface of the shaft, thereby increasing the cleaning range of the filter belt surface.

[0014] In this invention, the shaft and the collection mechanism work together. When the shaft is running, it carries the squeezing plate inside the collection mechanism to move back and forth inside the cleaning box. The squeezing plate and the pad work together to automatically compress and collect the foreign matter cleared from the surface of the filter belt, improving the ease of use.

[0019] A cleaning mechanism 9 that cooperates with the filter belt 6 is movably connected between the surface of the right shaft 8 and the side wall of the filter cylinder 2, and a collection mechanism 10 that cooperates with the filter belt 6 is movably connected between the end of the right shaft 8 and the base 1.

[0020] A motor 11 is fixedly connected to the left side of the filter cartridge 2. The rotating end of the motor 11 is fixedly connected to the end of the left shaft 8. Drain pipes 12 are symmetrically fixedly connected to the lower part of the filter cartridge 2. It should be noted that a support plate is fixedly connected to the surface of the motor 11, and the side wall of the support plate is fixedly connected to the side wall of the filter cartridge 2. After the motor 11 is started, it drives the synchronous pulley 7, the synchronous belt 5, and the filter belt 6 to run clockwise. The filtered reaction liquid inside the filter cartridge 2 is discharged from the drain pipe 12.

[0021] In this embodiment, as Figures 1 to 9 As shown, the cleaning mechanism 9 includes an incomplete gear 901, which is fixedly sleeved on the middle of the right-side shaft 8. A bracket 902 is fixedly connected to the lower right side of the filter cartridge 2. An adjusting gear 903 is rotatably connected to one end of the bracket 902 near the incomplete gear 901, and the side wall of the adjusting gear 903 meshes with the side wall of the incomplete gear 901. It should be noted that a support rod is rotatably connected to the middle of the bracket 902, and the adjusting gear 903 is fixedly connected to the middle of the support rod. When the shaft 8 rotates clockwise with the incomplete gear 901, the incomplete gear 901 meshes with the side wall of the adjusting gear 903 in stages, causing the adjusting gear 903 to rotate counterclockwise once in stages.

[0022] A support ring 904 is symmetrically rotatably connected to the surface of the right-side shaft 8. An arc-shaped air-blowing hood 905, which mates with the filter belt 6, is fixedly connected between the two support rings 904. An adjusting block 906 is symmetrically fixedly connected to the surface of the arc-shaped air-blowing hood 905. An adjusting groove 907 is formed in the middle of the adjusting block 906. An adjusting pin 908 is slidably connected to the inner wall of the adjusting groove 907. A U-shaped adjusting bracket 909 is fixedly connected between the two ends of the adjusting pin 908. It should be noted that the air-blowing end of the arc-shaped air-blowing hood 905 faces the surface of the filter belt 6. Here, the arc-shaped air-blowing hood 905 uses an exhaust hood as described in existing technology to ensure that the gas can be evenly discharged from the port position of the arc-shaped air-blowing hood 905.

[0023] Piston cylinders 910 are symmetrically and fixedly connected to the right side of filter cylinder 2. Piston rods 911 are slidably connected inside piston cylinders 910. Two piston rods 911 correspond one-to-one with two U-shaped adjusting brackets 909. One end of piston rod 911 passes through piston cylinder 910 and is fixedly connected to the end of the corresponding U-shaped adjusting bracket 909. A hinge rod 912 is fixedly connected to the middle of piston rod 911. U-shaped hinge blocks 913 are symmetrically and fixedly connected to the surface of adjusting gear 903. Two hinge rods 912 correspond one-to-one with two U-shaped hinge blocks 913. One end of hinge rod 912 is movably connected to the middle of U-shaped hinge block 913. A compression spring 914 is movably connected between the surface of the lower piston rod 911 and the inner wall of the corresponding piston cylinder 910. It should be noted that when the adjusting gear 903 rotates with the two U-shaped hinge blocks 913, the U-shaped hinge blocks 913 and the hinge rod 912 cooperate to slide, so that the hinge rod 912 carries the corresponding piston rod 911 to slide inside the piston cylinder 910. During the movement of the piston rod 911, it will deflect and swing on the surface of the shaft rod 8 through the cooperation of the U-shaped adjusting frame 909, adjusting pin 908 and adjusting block 906.

[0024] An intake head 915 is fixedly connected to one side of the piston cylinder 910, and an exhaust pipe 916 is fixedly connected to the other side of the piston cylinder 910. A spring hose 917 is fixedly connected to one end of the exhaust pipe 916, and one end of the spring hose 917 is fixedly connected to the surface of the arc-shaped air blowing cover 905. It should be noted that, due to the spring hose 917, the normal gas delivery inside the piston cylinder 910 will not be affected when the arc-shaped air blowing cover 905 deflects and swings.

[0025] In this embodiment, as Figures 1 to 9 As shown, a mounting ring is fixedly connected to the middle of the piston rod 911, and a hinge rod 912 is fixedly connected to the surface of the mounting ring.

[0026] Both sides of the U-shaped hinge block 913 are provided with waist-shaped grooves, and the hinge rod 912 is slidably connected between the two waist-shaped grooves.

[0027] In this embodiment, as Figures 1 to 9 As shown, a support bearing is fixedly connected to the inner ring of the support ring 904, and the inner ring of the support bearing is fixedly connected to the surface of the right-side shaft 8. It should be noted that the cooperation between the support bearing and the support ring 904 ensures the stability of the arc-shaped air blowing cover 905 as it deflects and swings on the surface of the shaft 8.

[0028] In this embodiment, as Figures 1 to 9As shown, a main check valve is fixedly connected to the end of the spring hose 917, and a slave check valve is fixedly connected to the end of the suction head 915. The slave check valve is set in the opposite direction to the main check valve. It should be noted that the one-way bearing is set to prevent gas inside the upper spring hose 917 from entering the lower spring hose 917 through the arc-shaped air blowing cover 905; and the slave check valve is set in the opposite direction to the main check valve to ensure that the piston rod 911 inside the piston cylinder 910 can stably perform suction and exhaust during the movement.

[0029] In this embodiment, as Figures 1 to 9 As shown, the collection mechanism 10 includes two turntables 1001, which are fixedly connected to the two ends of the right-side shaft 8. A sliding pin 1002 is fixedly connected to the side wall of each turntable 1001. A waist-shaped sliding plate 1003 is slidably connected to the surface of the sliding pin 1002. A telescopic rod 1004 is fixedly connected to one side of the waist-shaped sliding plate 1003. One end of the telescopic rod 1004 is fixedly connected to the side wall of the filter cylinder 2, and a pull rope 1005 is fixedly connected to the other side of the waist-shaped sliding plate 1003. It should be noted that the movable end of the telescopic rod 1004 cannot rotate; it can only move horizontally with the waist-shaped sliding plate 1003 to prevent the waist-shaped sliding plate 1003 from rotating and disengaging from the sliding pin 1002, thus affecting the performance.

[0030] A cleaning box 1006 is fixedly connected to the right side of the base 1. A groove 1007 that matches the filter belt 6 is opened on the left side of the cleaning box 1006. A guide plate 1008 is symmetrically fixedly connected to the middle of the inner wall of the groove 1007. A pad 1009 is slidably connected between the bottom of the guide plate 1008 and the inner bottom surface of the groove 1007. A compression spring 1010 is fixedly connected between the side wall of the pad 1009 and the inner wall of the groove 1007. A compression plate 1011 is provided between the two pads 1009. The top of the compression plate 1011 overlaps with the bottom of the guide plate 1008, and the side wall of the compression plate 1011 overlaps with the inner wall of the groove 1007. It should be noted that: foreign objects blown off the surface of the filter belt 6 are guided and transported to the middle position of the groove 1007 by the guide plate 1008. At this time, the extrusion plate 1011 moves back and forth inside the groove 1007 and cooperates with the two pads 1009 to compress the foreign objects.

[0031] One end of the pull rope 1005 passes through the pad 1009 on the same side and is fixedly connected to the side wall of the extrusion plate 1011. The bottom of the cleaning box 1006 has symmetrically arranged discharge grooves 1012, with each of the two discharge grooves 1012 corresponding to one of the two pads 1009. The bottom of the cleaning box 1006 also has a drainage groove 1013, with the two drainage grooves 1013 positioned between the two discharge grooves 1012. It should be noted that a filter plate is fixedly connected to the top of the drainage groove 1013. As the extrusion plate 1011 moves towards the corresponding pad 1009, the reaction liquid compressed from the foreign matter is discharged from the drainage groove 1013. As the extrusion plate 1011 continues to move and extrudes the pad 1009, when the pad 1009, carrying the compressed foreign matter, moves to the discharge groove 1012, the compressed foreign matter falls into the discharge groove 1012 and is discharged when the extrusion plate 1011 moves in the opposite direction.

[0032] In this embodiment, as Figures 1 to 9 As shown, the cleaning box 1006 has round holes on both sides, with each of the two round holes corresponding to one of the two pull ropes 1005. It should be noted that the pad 1009 also has a round hole in the middle that mates with the pull rope 1005; guide rollers are symmetrically rotatably connected to the outer wall of the cleaning box 1006, with each of the two guide rollers corresponding to one of the two pull ropes 1005. The guide rollers guide the pull ropes 1005, reducing the frictional resistance during the movement of the pull ropes 1005.

[0033] The two sliding pins 1002 are symmetrically arranged about the axis of the right shaft 8. It should be noted that by staggering the two sliding pins 1002, when the two turntables 1001 rotate synchronously, the two waist-shaped sliding plates 1003 can move synchronously in opposite directions. At this time, during the process of the two waist-shaped sliding plates 1003 cooperating with the two pull ropes 1005, the pull ropes 1005 pull the extrusion plate 1011 to move back and forth inside the groove 1007.

[0034] In this embodiment, as Figures 1 to 9 As shown, a method of using an allulose inversion reaction filtration device includes the following steps: S1. When in use, after the reaction liquid inside the reaction tank 3 enters the filter cylinder 2, the reaction liquid falls from the position of the filter tank 4 to the top position of the filter belt 6 between the two synchronous belts 5 for filtration. At this time, the motor 11 starts and rotates clockwise with the corresponding shaft 8. Under the transmission of the synchronous wheel 7, the two synchronous belts 5 drive the filter belt 6 to rotate continuously and switch the filtration position. S2. During the synchronous rotation of the right shaft 8, the right shaft 8 drives the incomplete gear 901 to rotate, causing the incomplete gear 901 to mesh with the adjacent adjusting gear 903 in stages. At this time, the adjusting gear 903 drives the two U-shaped hinge blocks 913 to rotate synchronously, causing the two U-shaped hinge blocks 913 to deflect in different directions. With the cooperation of the hinge rod 912, the two piston rods 911 also move in different directions and slide inside the corresponding piston cylinder 910. At this time, the upper piston rod 911 moves to the left. The gas inside the corresponding piston cylinder 910 is delivered to the exhaust pipe 916 and the spring hose 917, so that the gas is discharged from the end of the arc-shaped air blower 905. Then, the gas is blown from the back of the filter belt 6 to the filter surface, blowing the foreign objects on the filter surface of the filter belt 6 into the cleaning box 1006 for collection. Since the two piston rods 911 move in opposite directions, the two piston cylinders 910 are delivered into the arc-shaped air blower 905 in a staggered manner to continuously clean the surface of the filter belt 6. S3. Simultaneously, during the movement of piston rod 911, the U-shaped adjusting bracket 909 at the end of piston rod 911 cooperates with adjusting pin 908, causing adjusting pin 908 to slide inside adjusting groove 907 on the surface of corresponding adjusting block 906. Since the two piston rods 911 move back and forth in a staggered manner, the two piston rods 911, through the cooperation of U-shaped adjusting bracket 909 and adjusting block 906, swing back and forth on the surface of right shaft 8 with arc-shaped air blowing cover 905, increasing the cleaning range of filter belt 6. S4. Simultaneously, the rotation of the right-side shaft 8 causes the turntable 1001 to rotate synchronously. During the sliding process of the sliding pin 1002 and the waist-shaped slide plate 1003 on the surface of the turntable 1001, the waist-shaped slide plate 1003 and the corresponding telescopic rod 1004 move horizontally back and forth on the side wall of the turntable 1001. Due to the misalignment of the two sliding pins 1002, the two waist-shaped slide plates 1003 move back and forth inside the cleaning box 1006 through the pull rope 1005 with the squeezing plate 1011, pushing the foreign objects collected inside the cleaning box 1006 to the side wall of the corresponding pad 1009. At this time, the foreign objects are squeezed out of the liquid inside and discharged from the drain trough 1013 during the compression process. As the squeezing plate 1011 continues to move, it pushes the pad 1009 to move horizontally inside the groove 1007, pushing the compressed foreign objects to the upper position of the discharge trough 1012, so that the foreign objects can be automatically discharged from the discharge trough 1012 for collection.

6. The method of using the allulose inversion reaction filtration device according to claim 5, comprising the following steps: S1. When in use, after the reaction liquid inside the reaction tank (3) enters the filter cylinder (2), the reaction liquid falls from the position of the filter tank (4) to the top position of the filter belt (6) between the two synchronous belts (5) for filtration. At this time, the motor (11) is started and the corresponding shaft (8) rotates clockwise. Under the transmission of the synchronous wheel (7), the two synchronous belts (5) drive the filter belt (6) to rotate continuously and switch the filtration position. S2. During the synchronous rotation of the right shaft (8), the right shaft (8) rotates with the incomplete gear (901), causing the incomplete gear (901) to mesh with the adjacent adjusting gear (903) in stages. At this time, the adjusting gear (903) rotates synchronously with the two U-shaped hinge blocks (913), causing the two U-shaped hinge blocks (913) to deflect in different directions. With the cooperation of the hinge rod (912), the two piston rods (911) also move in different directions and slide inside the corresponding piston cylinder (910). At this time, the upper piston rod (911) moves to the left. The gas inside the corresponding piston cylinder (910) is delivered to the exhaust pipe (916) and spring hose (917), so that the gas is discharged from the end of the arc-shaped air blower (905). Then the gas is blown from the back of the filter belt (6) to the filter surface, blowing the foreign objects on the filter surface of the filter belt (6) into the cleaning box (1006) for collection. Since the two piston rods (911) move in opposite directions, the two piston cylinders (910) are misaligned and deliver gas into the arc-shaped air blower (905) to continuously clean the surface of the filter belt (6). S3. Simultaneously, during the movement of the piston rod (911), the U-shaped adjustment bracket (909) at the end of the piston rod (911) cooperates with the adjustment pin (908), causing the adjustment pin (908) to slide inside the adjustment groove (907) on the surface of the corresponding adjustment block (906). Since the two piston rods (911) move back and forth in a staggered manner, the two piston rods (911) are swung back and forth on the surface of the right shaft (8) through the cooperation of the U-shaped adjustment bracket (909) and the adjustment block (906) with the arc-shaped air blowing cover (905), increasing the cleaning range of the filter belt (6). S4. At the same time, the rotation of the right-side shaft (8) will cause the turntable (1001) to rotate synchronously. During the sliding process of the sliding pin (1002) on the surface of the turntable (1001) and the waist-shaped slide plate (1003), the waist-shaped slide plate (1003) and the corresponding telescopic rod (1004) will move horizontally back and forth on the side wall of the turntable (1001). Due to the misalignment of the two sliding pins (1002), the two waist-shaped slide plates (1003) will carry the squeezing plate (1011) in the cleaning box through the pull rope (1005). The internal reciprocating movement of (1006) pushes the foreign objects collected inside the cleaning box (1006) to the side wall of the corresponding pad (1009). At this time, the foreign objects are squeezed out of the liquid inside and discharged from the drain groove (1013) during the compression process. As the squeezing plate (1011) continues to move, it pushes the pad (1009) to move horizontally inside the groove (1007), pushing the compressed foreign objects to the upper part of the discharge groove (1012), so that the foreign objects can be automatically discharged from the discharge groove (1012) for collection.
