Description

TECHNICAL FIELD

[0001] The present application relates to the field of rutin extraction, and particularly relates to a cyclic extraction system for energy-saving rutin preparation. BACKGROUND

[0002] Rutin is a natural flavonoid glycoside, which belongs to flavonol glycosides widely existing in plants, and has effects of anti-inflammatory, anti-oxidation, anti-allergy and anti-virus. Rutin exists in perilla leaf, tobacco leaf, orange peel, tomato and the like, and is particularly rich in sophora flower and buckwheat flower. Rutin used in medicine is extracted from sophora flower in China.

[0003] The extraction methods of sophora flower rutin include decoction method, percolation method, immersion extraction method, reflux extraction method, supercritical fluid extraction method, ultrasonic extraction method and microwave-assisted extraction method. The decoction method and the reflux extraction method need to be heated to extract, and a certain amount of hydrolysate is generated. The supercritical fluid extraction method, the ultrasonic extraction method and the microwave-assisted extraction method are not suitable for large-scale production. The percolation method is a dynamic leaching method compared with the immersion extraction method, has high solvent utilization rate, and can completely leach effective components. At present, most domestic rutin production enterprises use the percolation method to extract rutin.

[0004] The sophora flower rutin is extracted by using the percolation method. The sophora flower is crushed, scalded, loaded into a percolation tank, soaked and percolated. In the percolation process, the percolation speed may be slow or even unable to discharge liquid due to too fine crushing particle size of the medicinal material or compaction of the medicinal material, so that the column needs to be reloaded and the extraction time is prolonged.

[0005] The present application provides a cyclic extraction system for energy-saving rutin preparation. The sophora flower is continuously extruded in the extraction process, so that the solution is repeatedly absorbed and then extruded, thereby effectively extracting the effective components. After the extraction is completed, the extraction liquid and waste residue can be conveniently separated, thereby affecting the extraction efficiency. Therefore, the present application provides a cyclic extraction system for energy-saving rutin preparation. SUMMARY

[0013] Through the above technical scheme, the meshing relationship between the transmission bevel gear and the driving bevel gear and the driven bevel gear can be controlled to realize the purpose of rotating the rotating shaft while driving the pressurizing mechanism to work.

[0014] As a further improvement of the above-mentioned scheme, the rotating shaft is externally sleeved with a mounting sleeve axially movable, the compression roller is rotationally connected to the outer periphery of the mounting sleeve, and an adjusting assembly is mounted on the rotating shaft for adjusting the height of the mounting sleeve.

[0015] Through the above technical scheme, the height of the compression roller can be adjusted by adjusting the height of the mounting sleeve, so as to adjust the height of the compression roller according to the amount of material in the extraction tank.

[0031] 1. By the cooperation between the rotating shaft, the compression roller and the stirring assembly, the raw material can be continuously extruded and stirred when the effective components in the raw material are soaked and extracted, so that the raw material can fully absorb the extraction solvent, and then under the extrusion of the compression roller, the effective components are extruded out, which not only helps to speed up the extraction speed of the effective components in the raw material, but also effectively improves the extraction degree of the effective components in the raw material

[0032] 2.

[0033] 3. By the cooperation between the lifting structure and the overturning mechanism, after the blocking block is withdrawn into the receiving bin, the fixed plate contacts the connecting block, and then starts to drive the sealing plate to rotate while the sealing plate gradually descends, so as to avoid the residue staying on the sealing plate, and at the same time, the moving plate descends and drives the moving plate to move outward of the discharge port, so as to facilitate the receiving hopper to discharge the residue in the extraction tank and push the receiving hopper out of the receiving bin, thereby facilitating the staff to collect the extraction liquid.

[0047] The top surface of the moving plate 27 is provided with a plurality of tooth grooves along the length direction, the turnover mechanism comprises a winding shaft rotatably connected to the inner wall of the receiving bin 1, a connecting rod 26 hingedly connected to the top of the moving plate 27, a linkage gear 31 sleeved on the outside of the winding shaft, a fixed cylinder 50 fixed to the inner wall of one side of the receiving bin 1, and a movable column 51 movably sleeved in the fixed cylinder 50, one end of the movable column 51 extends below the fixed cylinder 50 and is fixed with a connecting block 44, the connecting block 44 is located directly below the fixed block 43, the top of the movable column 51 extends above the fixed cylinder 50 and is fixed with a connecting rope 49, two guide wheels 48 are rotatably connected to the outer wall of the receiving bin 1, the other end of the connecting rope 49 is guided through the two guide wheels 48 and is fixed to the outer periphery of the winding shaft, the linkage gear 31 is located on the top of the moving plate 27 and is engaged with the tooth grooves on the top of the moving plate 27, the other end of the connecting rod 26 is hingedly connected to the bottom surface of the sealing plate 25, the bottom surface of the moving plate 27 and the bottom of the storage bin 55 are connected by an elastic member, the elastic member comprises a straight plate fixed to the bottom surface of the moving plate 27, a movable rod 28 fixed to the outer wall of one side of the straight plate close to the discharge port, and a limiting plate 29 movably sleeved on the outside of the movable rod 28, the limiting plate 29 is fixed to the bottom of the storage bin 55, a spring is sleeved on the outside of the movable rod 28, the spring is located between the straight plate and the limiting plate 29, one end of the spring is fixed to the straight plate, and the other end of the spring is fixed to the limiting plate 29, when the fixed block 43 contacts with the connecting block 44, the sealing plate 25 continues to descend with the continuous elongation of the telescopic member two 47, and at the same time the movable column 51 also descends synchronously, and at the same time the movable column 51 descends, the linkage gear 31 is driven to rotate counterclockwise by the connecting rope, so that the moving plate 27 moves outward of the discharge port at a higher speed, and the sealing plate 25 starts to rotate under the influence of the accelerated movement of the moving plate 27, so as to appear in an inclined state.

[0048] The stirring assembly comprises a mounting plate 16 fixed to the outer wall of the rotating shaft 14, a plurality of stirring rods 17 fixed to the bottom surface of the mounting plate 16, and a scraper 12 fixed to the bottom of the plurality of stirring rods 17, the bottom surface of the scraper 12 abuts against the bottom surface of the extraction tank 2, and the length of the scraper 12 is greater than the length of the discharge groove, so as to avoid the scraper 12 from falling into the discharge groove. The stirring rods 17 play a role in stirring the raw materials during extraction, and the scraper 12 can scrape the waste slag in the extraction tank to the slag discharge groove 23 when the waste slag is discharged.

[0049] The bottom of one side of the extraction tank 2 is provided with a discharge port, a filter screen is installed in the discharge port, a discharge pipe 35 is installed outside the discharge port, one end of the discharge pipe 35 extends into the storage bin 55, an electromagnetic valve is installed on the discharge pipe 35, a receiving hopper located directly below the discharge pipe 35 is placed on the top of the pull-out plate 32, and a control switch of the electromagnetic valve is installed on the electric control box 4.

[0050] The implementation principle in the embodiment is that when extracting, the sophora fruit is put into the extraction tank 2 after being crushed, scalded and washed, and then borax-lime water is added into the extraction tank 2, so as to extract the effective components in the raw materials in the extraction tank 2. When extracting, the telescopic part one 10 is first started to contract until the transmission bevel gear 40 is engaged with the driving bevel gear 38 and the driven bevel gear 6, and then the telescopic part one 10 is stopped to contract, and then the motor 7 is started to rotate. After the motor 10 rotates, the rotating shaft 14 rotates, the compression roller 20 starts to continuously roll over the raw materials in the extraction tank 2 with the rotation of the rotating shaft 14, and the stirring assembly continuously stirs the rolled raw materials again, so that the raw materials can fully absorb the extraction solution again. At the same time, the rotation of the rotating shaft 14 drives the driven bevel gear 6 to rotate, and the driven bevel gear 6 rotates and then drives the piston plate 11 to move repeatedly in the air cylinder 5 through the piston rod 42, so that the air outside can be continuously sucked into the air cylinder 5 first, and then is squeezed into the extraction tank 2 from the air cylinder 5, so as to increase the pressure in the extraction tank 2. The pressure in the extraction tank 2 can be monitored in real time through the pressure gauge. When the pressure in the extraction tank 2 reaches the set value, the telescopic part one 10 is started to lengthen, so that the transmission bevel gear 40 is separated from the driving bevel gear 38. In this way, the rotation of the rotating shaft 14 will not drive the driven bevel gear 6 to rotate, and the pressure increasing mechanism will not increase the pressure in the extraction tank 2 again.

[0051] After the extraction is completed, the electromagnetic valve is opened again, and the extraction liquid in the extraction pipe 2 can enter the storage bin 55 inside through the discharge pipe 35, and finally falls into the receiving hopper. The raw material waste is intercepted in the extraction tank 2 by the filter screen. When the extraction liquid is discharged, the transmission bevel gear 40 can be engaged with the driven bevel gear 38 again, so that the extraction liquid can be discharged while the pressure in the extraction tank 2 is continuously increased, so as to speed up the discharge speed of the extraction liquid. In order to ensure that the effective components in the raw materials are extracted completely, the raw materials can be extracted twice or three times.

[0052] When the extraction liquid in the extraction tank 2 is emptied, the transmission bevel gear 40 is disengaged from the driving bevel gear 38, and then the second telescopic member 47 is extended, thereby driving the fixed block 43 to descend, and then the sealing plate 25 is lowered, so that the blocking block 23 can gradually exit to the outside of the slag discharge groove 54. During the descent of the sealing plate 25, the abutment column 46 is limited and the connecting rod 26 is limited, so that the sealing plate 25 always maintains a state of being parallel to the bottom surface of the slag discharge groove 54 before the blocking block 23 completely enters the receiving bin 1. After the sealing plate 25 is lowered, the connecting rod 26 is compressed to move the moving plate 27 outward of the discharge port, thereby gradually pushing the receiving hopper to the outside of the receiving bin 1. After the blocking block 23 completely enters the receiving bin 1 and the fixed block 23 touches the connecting block 44, the movable column 51 starts to descend synchronously with the sealing plate 25 as the second telescopic member 47 continues to extend. After the movable column 21 is lowered, the connecting rope 49 is pulled, so that the connecting rope 49 wound outside the reel is unwound, and the reel starts to rotate counterclockwise under the action of the stretching 49, thereby accelerating the moving speed of the moving plate 27 moving outward of the discharge port, so that the balance of the sealing plate 25 driving the moving plate 27 to move is broken, and the sealing plate 25 starts to rotate downward. Thus, the sealing plate 25 gradually tilts until the receiving hopper completely moves to the outside of the receiving bin 1, and then the extension of the second telescopic member 47 is stopped. Then the motor 7 rotates, and the scraper 12 rotates with the rotating shaft 14, thereby gradually scraping the waste slag in the extraction tank 2 into the slag discharge groove 54. Then the waste slag falls into the receiving bin 1 and is discharged from the slag discharge hole at the bottom of the receiving bin 1. During the movement of the moving plate 27 to the outside of the discharge port, the spring 2 is continuously compressed. When the second telescopic member 47 starts to contract, the spring 2 starts to recover and extend, thereby driving the moving plate 27 to move to the inside of the receiving bin 1, and also driving the sealing plate 25 to flip upward until one end of the abutment column 46 abuts against the outer wall of the fixed plate 30. At this time, the sealing plate 25 returns to a state of being parallel to the bottom surface of the slag discharge groove 54. Finally, as the second telescopic member 47 continues to contract, the sealing plate 25 continues to move upward until the blocking block 23 is reinserted into the slag discharge groove 54, and the moving plate 27 also returns to the original position with the upward movement of the sealing plate 25, thereby reinserting the receiving hopper into the receiving bin 55.
