[0024] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0025] Example

[0026] like Figure 1-5 As shown, a theanine chelate preparation system includes a conical mixing drum body 2, a driving motor 1 is installed on the top of the conical mixing drum body 2, and a pH adjustment device and a nitrogen purge device are also installed on the conical mixing drum body 2. The output shaft of the driving motor 1 is connected to a hollow stirring shaft 7 through a transmission assembly. A fixed rod 10 is fixed in the hollow stirring shaft 7, and the fixed rod 10 is rotatably connected to the hollow stirring shaft 7 through a bearing. The motor 1 can drive the hollow stirring shaft 7 to rotate. The hollow stirring shaft 7 and the fixed rod 10 are coaxially arranged. The hollow stirring shaft 7 is rotatably connected to the fixed rod 10 through a bearing. The motor 1 drives the hollow stirring shaft 7 to rotate through a transmission gear or a belt.

[0027] A hollow stirring paddle 5 is fixed on the hollow stirring shaft 7, and a slide groove 501 is provided on the hollow stirring paddle 5 along the length direction. A sliding block 6 is slidably connected to the hollow stirring paddle 5. A reciprocating screw is rotatably connected to the hollow stirring paddle 5 through a bearing. One end of the reciprocating screw is inserted into the hollow stirring shaft 7 and is fixedly connected to the first bevel gear 12. A second bevel gear 11 is fixed on the fixed rod 10. The first bevel gear 12 is meshed with the second bevel gear 11. A first elastic sealing sleeve 9 is provided on the outer sleeve of the hollow stirring paddle 5. By fixing one end of the hollow stirring paddle 5 to the hollow stirring shaft 7, the hollow stirring paddle 5 can be driven to rotate by the hollow stirring shaft 7. Since the hollow stirring paddle 5 is provided with a slide groove 501 along the length direction, there is also a slide in the sliding space. A sliding block 6 is connected, and the sliding block 6 includes an external supporting portion and an internal sliding portion 601. The supporting portion and the sliding portion 601 are fixedly connected by a connecting section, and the connecting section is adapted to the slide groove 501. The sliding portion 601 is provided with a through hole 602, and the reciprocating screw passes through the through hole 602. A reciprocating guide groove is provided on the reciprocating screw. The sliding portion 601 is fixed with an extension section 603 extending into the reciprocating guide groove. When the motor 1 drives the hollow stirring paddle 5 to rotate, it will simultaneously drive the reciprocating screw to rotate around the fixed rod 10, so that the sliding block 6 can slide back and forth along the hollow stirring paddle 5. During the reciprocating sliding process of the sliding block 6, it plays a supporting role on the first elastic sealing sleeve 9 that fits tightly on the hollow stirring paddle 5.

[0028] A bearing seat is installed at the bottom of the conical mixing drum body 2, and the hollow mixing shaft 7 is rotatably connected to the conical mixing drum body 2 through the bearing seat. A lever 4 is fixed to the lower end of the hollow mixing shaft 7 and is in contact with the wall of the conical mixing drum. The hollow mixing shaft 7 will simultaneously drive the lever 4 to rotate during the rotation process. At the same time, there is an angle between the lever 4 and the hollow stirring paddle 5. The lever 4 is located in front of the hollow stirring paddle 5, so that the hollow stirring paddle 5 will drive the water flow to form a flushing effect in the direction of the lever 4 during the rotation process.

[0029] A fixing ring 3 is installed on the upper part of the conical mixing drum body 2, and a sealing bearing 8 is installed on the lower part of the hollow mixing shaft 7. A second elastic sealing sleeve is provided between the fixing ring 3 and the sealing bearing 8. The fixing ring 3 and the sealing bearing 8 prevent the second elastic sealing sleeve from rotating as the lever 4 rotates.

[0030] The first elastic sealing sleeve 9 and the second elastic sealing sleeve are evenly distributed with circular grooves 13 on the inner side and a smooth surface on the outer side. Under the action of hydraulic pressure, the side of the first elastic sealing sleeve 9 and the second elastic sealing sleeve that contacts the wall of the conical mixing drum and the hollow stirring paddle 5 will be squeezed, so that the gas in the circular groove 13 will be discharged to the upper part where there is no hydraulic pressure. After the air pressure in the circular groove 13 is discharged, the first elastic sealing sleeve 9 and the second elastic sealing sleeve are further attracted to the surface, making it difficult for the first elastic sealing sleeve 9 and the second elastic sealing sleeve to be misaligned.

[0031] The shape of the outer side of the lever 4 is adapted to the wall of the conical mixing drum, and the shape of the inner side is parabolic. An air channel is provided in the rod body of the lever 4, and one end of the air channel is connected to the top of the lever 4. The top of the lever 4 is close to the fixing ring 3. A plurality of strip holes connected to the air channel are evenly provided on the inner side of the lever 4. A protrusion adapted to the circular groove 13 is provided on the surface of the lever 4. By providing the air channel and the strip holes, it is easier for the lever 4 to expand the second elastic sealing sleeve. The protrusion can form an arc-shaped protrusion after the second elastic sealing sleeve is supported, further expanding the surface of the supported second elastic sealing sleeve, and forming a smooth protrusion to enhance the scouring effect of the water flow. The attachment point is destroyed by a sharp change, and the scouring effect is enhanced, so that the ferrous salt can be further washed down.

[0032] The outer side of the sliding block 6 is also provided with a protrusion, and when the sliding block 6 expands the first elastic sealing sleeve 9, the first elastic sealing sleeve 9 can also form a protruding smooth surface.

[0033] The working principle of this application is:

[0034] When the chelating reaction is carried out, the hollow stirring shaft 7 is driven to rotate by the motor 1. At this time, the internal fixed rod 10 is in a fixed state. Since one end of the hollow stirring paddle 5 is fixedly connected to the hollow stirring shaft 7, the hollow stirring shaft 7 will drive the hollow stirring paddle 5 to rotate at the same time when it rotates. A sliding space is provided inside the hollow stirring paddle 5. A reciprocating screw is installed in the sliding space along the length direction. The reciprocating screw is rotatably connected to the hollow stirring paddle 5 through a bearing, so the reciprocating screw can rotate freely. A sliding block 6 is also connected to the slide in the sliding space. The sliding block 6 includes an external support portion and an internal sliding portion 601. The support portion and the sliding portion 601 are fixedly connected by a connecting section. A slide groove 501 is provided on the hollow stirring paddle 5 along the length direction. The connecting section is located in the slide groove 501, and the connecting section is adapted to the slide groove 501. The sliding portion 601 has a through hole 6 02, the reciprocating screw passes through the through hole 602, and a reciprocating guide groove is provided on the reciprocating screw. The sliding part 601 is fixed with an extension section 603 extending into the reciprocating guide groove. When the motor 1 drives the hollow stirring paddle 5 to rotate, it will simultaneously drive the reciprocating screw to rotate around the fixed rod 10. Since the first bevel gear 12 is fixed to the end of the reciprocating screw, and the second bevel gear 11 is fixed to the fixed rod 10, the first bevel gear 12 is engaged with the second bevel gear 11. Therefore, when the reciprocating screw rotates around the fixed rod 10, the reciprocating screw is rotated by the gear action. The rotation of the reciprocating screw drives the sliding block 6 to slide back and forth along the reciprocating guide groove. Since the first elastic sealing sleeve 9 is tightly attached to the hollow stirring paddle 5, the support portion will prop up the first elastic sealing sleeve 9 that is attached to the surface of the hollow stirring paddle 5 during the movement, so that the propped up part is expanded;

[0035] Since the first elastic sealing sleeve 9 and the second elastic sealing sleeve are evenly distributed with circular grooves 13 on one side of the tapered mixing drum body 2 and the hollow stirring paddle 5, when the first elastic sealing sleeve 9 and the second elastic sealing sleeve are pressed against the smooth surface under the action of hydraulic pressure, the circular grooves 13 will be flattened, so that the outer surfaces of the first elastic sealing sleeve 9 and the second elastic sealing sleeve are concave. When the first elastic sealing sleeve 9 and the second elastic sealing sleeve are propped up, the outer surfaces of the first elastic sealing sleeve 9 and the second elastic sealing sleeve will be smoothed and further expanded, and the adsorption effect of the ferrous salt will be destroyed by the rapid deformation of the surface. Under the action of water flow, the ferrous salt is desorbed;

[0036] During the reaction process, since the first elastic sealing sleeve 9 and the second elastic sealing sleeve are fitted to the conical mixing drum body 2 and the hollow stirring paddle 5 and are evenly provided with circular grooves 13, when the first elastic sealing sleeve 9 and the second elastic sealing sleeve are pressed against the smooth surface under the action of hydraulic pressure, the circular grooves 13 will be flattened, so that the outer surfaces of the first elastic sealing sleeve 9 and the second elastic sealing sleeve have a concave shape, thereby increasing the surface area and surface roughness, providing more adsorption sites and adsorption surfaces, thereby increasing the adsorption of ferrous salts, causing ferrous salts to be more effectively adsorbed on the surface, and the concentration of ferrous salts in the solution can be reduced by the adsorption of ferrous salts, so that the equilibrium position moves toward the side of the chelated product, thereby increasing the reaction speed;

[0037] Subsequently, the first elastic sealing sleeve 9 and the second elastic sealing sleeve are expanded and smoothed by the action of the sliding block 6 and the lever 4. The first elastic sealing sleeve 9 and the second elastic sealing sleeve are expanded from the wrinkled state to a smooth convex state. During the flow of water, the convex surface is affected by the scouring of the water flow, and the rapid deformation changes the attachment point, so that the ferrous salt is re-sent into the solution under the dual influence of the scouring of the water flow and the change of the attachment point. The concentration of the ferrous salt in the internal solution is in dynamic change, which can change the equilibrium position, improve the reaction efficiency, and avoid the adhesion of ferrous salts leading to incomplete reaction. As this dynamic process proceeds, all the ferrous salts will eventually be reacted to avoid the adhesion of ferrous salts.

[0038] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
