Description

Technical Field

[0001] The utility model relates to a separation device, in particular to a separation device for acid-controllable degradation of polysaccharides. Background Art

[0002] Polysaccharides are high-molecular carbohydrates composed of sugar chains linked by glycosidic bonds, consisting of at least ten monosaccharides. Polysaccharides composed of the same monosaccharides are called homopolysaccharides, such as starch, cellulose and glycogen; polysaccharides composed of different monosaccharides are called heteropolysaccharides, such as gum arabic, which is composed of pentose and galactose. Polysaccharides are not a pure chemical substance, but a mixture of substances with different degrees of polymerization. Polysaccharides are generally insoluble in water, have no sweet taste, cannot form crystals, and have no reducing properties or mutarotation. Polysaccharides can be extracted by water extraction and acid-base extraction.

[0003] The separation efficiency of polysaccharides can be improved by acid-base extraction. Controlling the amount of acid and base added can not only improve the separation efficiency, but also improve the separation purity. The current acid-controlled degradation of polysaccharides requires the raw materials to be switched between multiple equipment for processing. The switching causes the raw materials to come into contact with the air, which reduces the separation efficiency of the polysaccharides during the switching process. In addition, when the polysaccharides are centrifuged, the operating steps of the centrifugal separation device are relatively cumbersome, and the amount of polysaccharides separated at one time is small.

[0038] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0039] See also Figures 1 to 11 In an embodiment of the present invention, a separation device for acid-controlled degradation of polysaccharides includes a reaction structure and a stirring structure connected to the reaction structure, wherein the reaction structure and the stirring structure are connected via a filtering structure, and the stirring structure is connected to the separation structure;

[0040] The separation structure includes a diversion mechanism, a rotating drum 24 disposed below the diversion mechanism, a centrifugal drum 27 disposed on the rotating drum 24, and a lifting mechanism rotatably connected to the rotating drum 24;

[0041] The lifting mechanism is used to drive the rotating drum 24 to move closer to or away from the diverter mechanism in the vertical direction, and is used to assemble and disassemble the centrifugal drum 27 on the rotating drum 24 after the rotating drum 24 moves away from the diverter mechanism.

[0042] In this embodiment, the polysaccharide raw material is added to the interior of the reaction structure, and the acid solvent is added to the interior of the reaction structure to mix the polysaccharide raw material and the acid solvent. The mixed polysaccharide raw material enters the interior of the filtration structure, and the plant impurities in the raw material are filtered out by the filtration structure to improve the separation purity of the polysaccharide. The filtered raw material enters the interior of the stirring structure, and by adding an alcohol solvent into the stirring structure, the raw material can be separated by solubility differences. The raw material mixed with the alcohol solvent enters the separation structure to achieve centrifugal separation. The diversion mechanism can enable the raw material to be added to the separation structure. The raw materials flow into the interior of multiple centrifugal cylinders 27 respectively, and the rotating cylinder 24 rotates, so that the multiple centrifugal cylinders 27 circumferentially arranged on the rotating cylinder 24 rotate centrifugally, and the raw materials mixed with alcohol solvents are centrifugally separated, so that the raw materials are precipitated to meet the separation needs. The lifting mechanism can make the rotating cylinder 24 vertically close to or away from the diversion mechanism, so that a gap is generated between the rotating cylinder 24 and the diversion mechanism, which facilitates the removal of the centrifugal cylinder 27 from the rotating cylinder 24, improves the centrifugal separation effect, and reduces the exposure of the raw materials to the air when switching between the various devices, resulting in the separation purity being affected.

[0043] As a further solution of the present invention, the separation structure further includes a top cover 8, three columns 15 fixed in an array along the circumference of the top cover 8, and a bottom plate 17 fixed to the bottom of the three columns 15;

[0044] A first rotation groove 14 is formed on the inner wall of the top cover 8 , a vertical slide groove 16 is formed vertically on each of the upright posts 15 , and a fixing seat 18 is fixedly provided at the top center of the chassis 17 .

[0045] In this embodiment, the chassis 17 is used for fixed installation of the fixed seat 18. The chassis 17 is connected to the bottom of the three columns 15, so that the three columns 15 are connected and fixed. The top of the column 15 is fixed to the top cover 8. The column 15 is used to support the top cover 8 off the ground, meeting the overall connection effect.

[0046] As a further solution of the present invention, the diverter mechanism includes a collecting tray 19, a diverter cone 21 fixed at the center of the collecting tray 19, and a prismatic column 23 fixed at the center below the diverter cone 21;

[0047] The outer wall of the collecting tray 19 is integrally formed with a first rotating ring 20, which is rotatably connected to the first rotating groove 14. A plurality of discharge ports 22 are arranged in a circumferential array at a portion between the collecting tray 19 and the diverter cone 21.

[0048] In this embodiment, the collecting tray 19 is used to collect raw materials. The diverter cone 21 at the center of the collecting tray 19 can divert the falling raw materials so that the raw materials are diverted to multiple discharge ports 22. The first rotating ring 20 provided on the outer wall of the collecting tray 19 is rotatably connected to the first rotating groove 14, so that the diversion mechanism can rotate inside the top cover 8 to meet the needs of centrifugal separation.

[0049] As a further solution of the present invention, a plurality of embedding grooves 25 are provided on the rotating drum 24 corresponding to the discharge port 22, and a snap-fit ​​groove 26 is provided on the rotating drum 24 at the top of the embedding groove 25, and the centrifugal drum 27 is installed in the embedding groove 25;

[0050] The top of the centrifugal cylinder 27 is integrally formed with a boss 28. The diameter of the boss 28 is larger than the diameter of the centrifugal cylinder 27. The boss 28 is engaged with the engaging groove 26. The diameter of the centrifugal cylinder 27 is larger than the diameter of the discharge port 22. The boss 28 is arranged corresponding to the discharge port 22.

[0051] A plug-in slot for vertically slidingly plugging into the prismatic output shaft of the motor 30 is provided at the bottom center of the rotating cylinder 24. The motor 30 is installed in the fixed seat 18. A slot hole for vertically slidingly plugging into the prismatic column 23 is provided at the top center of the rotating cylinder 24. A second rotating ring 29 is fixedly connected to the outer wall of the rotating cylinder 24.

[0052] In this embodiment, the motor 30 drives the rotating drum 24 to rotate, and multiple centrifugal drums 27 circumferentially distributed on the rotating drum 24 are diverted by the diversion mechanism. Each centrifugal drum 27 is filled with polysaccharide raw materials. The rotating drum 24 rotates, so that the polysaccharide raw materials inside the centrifugal drum 27 are centrifuged to accelerate the sedimentation and stratification. A sealing ring is provided on the top of the boss 28, and the diameter of the centrifugal drum 27 is larger than the diameter of the discharge port 22, to ensure that the raw materials diverted from the discharge port 22 by the diversion mechanism can fall into the centrifugal drum 27 for collection. When it is necessary to disassemble the centrifugal drum 27 from the rotating drum 24, the centrifugal drum 27 is lifted up, and the boss 28 is disengaged from the engaging groove 26, so that the centrifugal drum 27 can be easily removed from the embedding groove 25, so as to meet the needs of pouring out the raw materials after centrifugal separation.

[0053] As a further solution of the present invention, the lifting mechanism includes a lifting ring 31 and three cylinders 34 arranged in a circular array at the bottom of the lifting ring 31. The bottom of the lifting ring 31 is fixedly connected to the piston rod of the cylinder 34, and the bottom of the cylinder 34 is fixedly connected to the chassis 17.

[0054] The inner wall of the lifting ring 31 is provided with a second rotating groove 32 , which is rotatably connected to the second rotating ring 29 . The outer wall of the lifting ring 31 is integrally provided with a slider 33 , which is slidably connected in the vertical sliding groove 16 .

[0055] In this embodiment, the lifting ring 31 can be raised and lowered by telescopic adjustment of the piston rod of the cylinder 34. Since the slider 33 fixed on the outer wall of the lifting ring 31 is slidably connected in the vertical slide groove 16, the lifting ring 31 can only be adjusted by vertical sliding. By lifting and lowering the lifting ring 31, the distance between the rotating cylinder 24 and the diversion mechanism can be controlled, so that the boss 28 is in conflict with or away from the bottom of the collecting plate 19, which satisfies the assembly and disassembly of the centrifugal cylinder 27 on the rotating cylinder 24. The lifting ring 31 is rotatably arranged with the rotating cylinder 24, so that when the lifting ring 31 is raised and lowered and the movement stroke is adjusted, it will not affect the rotation of the rotating cylinder 24, thereby ensuring the use effect.

[0056] As a further solution of the present invention, the reaction structure includes a reactor 1, a first filling port 9 and a first stirring member 10 respectively arranged on both sides of the top of the reactor 1;

[0057] The bottom of the reactor 1 is connected to the liquid inlet of the first pump 2 through a connecting pipe. A controller 3 is provided on one side of the first pump 2.

[0058] In this embodiment, through the first filling port 9 and the first stirring member 10 provided on the reactor 1, the first filling port 9 can be used for filling the polysaccharide raw material and the acid solvent, the first stirring member 10 can stir and mix the raw materials filled into the reactor 1, thereby improving the mixing reaction effect of the raw materials, and the first pump 2 can pump the raw materials inside the reactor 1 into the next device, thereby reducing the transfer of the raw materials between the devices during the exposure process and improving the separation purity of the polysaccharide. The controller 3 is electrically connected to the various components of the device through a conductive line for controlling the operating state of the device.

[0059] As a further solution of the present invention, the filtering structure includes a filter tank 4 and a filter cartridge 11 detachably mounted on the filter tank 4;

[0060] The top of the filter tank 4 is connected to the liquid outlet of the first pump 2 through a connecting pipe, and the bottom of the filter tank 4 is connected to the liquid inlet of the second pump 5 through a connecting pipe.

[0061] In this embodiment, the filter tank 4 is used to filter plant impurities in the raw materials to improve the separation purity. The detachable filter cartridge 11 provided on the filter tank 4 can be disassembled and cleaned after the filtering effect of the filter cartridge 11 is reduced to ensure the filtering effect. By connecting the first pump 2 to the filter tank 4, the raw materials inside the reactor 1 can be pumped into the filter tank 4 for filtration, and the second pump 5 is used to pump the raw materials inside the filter tank 4 out for use.

[0062] As a further solution of the present invention, the stirring structure includes a stirring tank 6 and a second filling port 12 and a second stirring member 13 respectively arranged on both sides of the top of the stirring tank 6;

[0063] The top of the stirring tank 6 is connected to the liquid outlet of the second pump 5 through a connecting pipe, the bottom of the stirring tank 6 is connected to the liquid inlet of the third pump 7 through a connecting pipe, and the liquid outlet of the third pump 7 is connected to the top center of the top cover 8 through a connecting pipe.

The second stirring member 13 provided on the stirring tank 6 can stir and mix the raw materials inside the stirring tank 6 so that the raw materials and the alcohol solvent are fully mixed. By connecting the stirring tank 6 to the third pump 7, the third pump 7 can pump the raw materials inside the stirring tank 6 into the separation structure for centrifugal separation, so that the separation process of the polysaccharide is coherent and efficient, thereby improving the separation efficiency.

[0065] The above embodiments are exemplary rather than restrictive, so any technical solution of the present invention that can be implemented in other specific forms without departing from the spirit or basic features of the present invention is included in the present invention.
