Description

Technical Field

[0001] The present invention relates to the technical field of mixed reactions, in particular to a chelating reaction device and a reaction method for preparing glycine. Background Art

[0002] The glycine chelation reaction is a process in which the amino (-NH2) and carboxyl (-COOH) groups of glycine (aminoacetic acid) form cyclic chelates with metal ions (such as calcium, iron, and zinc). It is widely used in food additives, medicine, agriculture, and other fields. In the glycine chelation reaction, a reaction device is usually required to mix the materials. However, existing reaction devices have the following problems when used:

[0003] The chelation reaction of glycine typically requires a step-by-step process. Different stirring speeds are required in the early and late stages of the reaction, effectively preventing internal imbalance and improving reaction efficiency. However, existing reaction apparatuses are not convenient for adjusting the stirring effect and shear force based on the rotational speed. Initially, the stirring speed is slow, while later, it is accelerated. Without this adjustment, the faster the speed, the greater the shear force, which can easily cause the chelate structure to break or the solution to stratify. Furthermore, during the chelation reaction, to prevent metal ion precipitation caused by pH fluctuations in the solution, a buffer solution is typically added in real time to adjust the internal pH. However, existing reaction apparatuses are not convenient for quickly and evenly distributing the buffer solution, resulting in an internal pH imbalance and affecting reaction efficiency.

[0004] In response to the above problems, it is urgent to carry out innovative design based on the original one. Summary of the Invention

[0009] The resistance adjustment component is arranged in the stirring shaft and is used to adjust the initial length of the elastic telescopic rod.

[0010] Preferably, the stirring plates are distributed at equal angles on the outside of the stirring shaft, and the initial positions of the lateral cross sections of the stirring plates are inclined.

[0011] Preferably, a guide groove with a spiral structure is provided on the outer side of the inner shaft, a guide head is slidably provided in the guide groove, and the guide head is fixed on the inner wall of the mounting sleeve.

[0012] Preferably, the shear holes are distributed at equal intervals on the stirring plate and the inner plate, and the positions of the shear holes on the stirring plate and the inner plate are staggered in the initial state.

[0013] Preferably, the guide plates are evenly distributed with small holes, the guide plates are distributed at equal angles on the outside of the stirring shaft, and the guide plates are tilted downward from the outside to the inside.

[0014] Preferably, the height adjustment assembly includes a rack, which is embedded in the stirring shaft and slides vertically. A push head is provided at the bottom of the rack, and the push head is fixed to the telescopic part of the outer end of the elastic telescopic rod. A tooth roller is engaged on the inner side of the rack, and the tooth roller drives the mounting rod to rotate and install in the stirring shaft through a torsion spring. A sealing plate is fixed in the middle of the mounting rod, and the sealing plate is fitted and slidably installed in the cavity on the side of the stirring shaft.

[0015] Preferably, the outer side of the top of the push head is set as a slope structure, and when the push head moves outward, it pushes the rack to move upward. The sealing plate is designed as an arc structure, and the moving trajectory of the sealing plate corresponds to the gear roller.

[0016] Preferably, the resistance adjustment assembly includes a screw, the screw seal is set at the bottom of the mixing tank and the stirring shaft, the threaded sleeve on the screw is provided with an adjustment rod, the adjustment rod is slidingly set in the cavity at the bottom of the stirring shaft, an adjustment strip is fixed on the outside of the adjustment rod, the top of the adjustment strip is located in the adjustment groove, and the adjustment groove is opened at the bottom of the mounting plate.

[0017] Preferably, the top of the adjustment slot is designed to be an inclined structure, and the adjustment slot is resisted by the upward movement of the adjustment bar to drive the mounting plate to move inward.

[0018] Preferably, the method comprises the following steps:

[0019] S1: According to the concentration of the reaction solution, the initial position of the mounting plate is adjusted through the resistance adjustment component to adjust the initial resistance of the elastic telescopic rod;

[0020] S2: Add the reaction materials into the mixing tank, and use the motor to drive the stirring shaft to rotate. During the reaction process, the speed of the stirring shaft is gradually increased. The centrifugal force is used to drive the stirring plate to move outward by a corresponding distance and rotate by a corresponding angle to reduce the shear force.

[0021] S3: During the reaction, a buffer solution is added to the mixing tank to adjust the pH value. The solution drips onto the rotating guide plate for guidance and uniform distribution. The angle adjustment component adjusts the inclination angle of the guide plate according to the rotation speed to prevent the solution from spilling around in large quantities. During the entire reaction process, the internal temperature is adjusted in real time by the built-in temperature control mechanism.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] According to the present invention, as the speed of the stirring shaft increases, the centrifugal force increases accordingly. At this time, under the action of the centrifugal force, the mounting sleeve and the stirring plate move outward, and the mounting sleeve and the stirring plate rotate synchronously through the guide groove and the guide head. On the one hand, when the stirring plate moves outward, under the condition of large centrifugal force, the stirring space is increased to avoid the accumulation of materials outside. On the other hand, the rotation of the stirring plate gradually changes from an inclined direction to a horizontal direction, reducing resistance and reducing the shear force on the materials. Furthermore, the overlapping space of the shear holes on the stirring plate and the inner plate is increased, so that when the solution enters the shear hole, the mixing effect is improved while the shear force can be reduced again, thereby ensuring the stable reaction of the material at different stirring speeds.

[0024] The present invention provides an inwardly inclined guide plate above the stirring plate, so that when the buffer solution is added, it falls onto the guide plate. The rotating guide plate cooperates with the small holes thereon to evenly distribute the solution below. At the same time, the inclined guide plate can resist centrifugal force and prevent most of the solution from being thrown to the peripheral area. Furthermore, as the rotation speed and centrifugal force increase, the mounting sleeve drives the outer end of the elastic telescopic rod to extend and retract, and the inclination angle of the guide plate is adjusted by the angle adjustment component, effectively preventing the solution from being easily thrown to the peripheral area when the centrifugal force increases. By adjusting the angle of the guide plate according to the change of centrifugal force, the uniform distribution efficiency of the buffer solution can be effectively improved.

[0025] The present invention can also enable the mounting sleeve and the stirring plate to move to different degrees in response to centrifugal force according to the reaction requirements of different materials. That is, by rotating the screw, the adjustment rod is driven to move upward, and the adjustment bar and the adjustment groove are used to push the mounting plate to move, and the initial elastic resistance of the elastic telescopic rod is adjusted. Under the same centrifugal force change law, the moving distance of the stirring plate can be adjusted, thereby improving the applicability of the reaction device. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] See also Figures 1-6 The present invention provides a technical solution: a chelating reaction device for preparing glycine, comprising a mixing tank 1, in which a stirring shaft 2 is installed through a motor; further comprising a mounting plate 3, which is embedded and slidably installed in the stirring shaft 2, and a mounting sleeve 5 is connected to the outer side of the mounting plate 3 through an elastic telescopic rod 4, a protrusion is provided in the middle of the mounting sleeve 5 and is limitedly provided on the outer side of the stirring shaft 2, a stirring plate 6 is fixed to the outer end of the mounting sleeve 5, an inner shaft 7 fixed to the side cavity of the stirring shaft 2 is provided in the mounting sleeve 5, an inner plate 9 is rotatably installed on the outer end of the inner shaft 7 through a connecting rod 8, the inner plate 9 is slidably arranged in the inner cavity of the stirring plate 6, and shear holes 91 are opened on both the inner plate 9 and the stirring plate 6;

[0035] The stirring plates 6 are distributed at equal angles on the outside of the stirring shaft 2, and the initial position of the lateral cross-section of the stirring plates 6 is inclined; a spiral guide groove 71 is opened on the outside of the inner shaft 7, and a guide head 72 is slidingly arranged in the guide groove 71, and the guide head 72 is fixed to the inner wall of the mounting sleeve 5; the shear holes 91 are distributed at equal intervals on the stirring plates 6 and the inner plate 9, and the positions of the shear holes 91 on the stirring plates 6 and the inner plate 9 are staggered in the initial state;

[0036] The reaction materials are introduced into the mixing tank 1, and the stirring shaft 2 is driven to rotate by the motor. The internal reaction temperature is controlled in real time by the built-in temperature control mechanism. When the stirring shaft 2 rotates, the speed is gradually adjusted according to the reaction time. Under the action of centrifugal force, the partial elastic resistance of the elastic telescopic rod 4 is overcome, so that the mounting sleeve 5 moves outward, driving the stirring plate 6 to move outward. In this process, the mounting sleeve 5 rotates on the inner shaft 7 through the conduction of the guide groove 71 and the guide head 72, thereby causing the stirring plate 6 to move laterally and rotate synchronously, and driving the connecting rod 8 and the inner plate 9 to rotate on the inner shaft 7.

[0037] As an embodiment of the present invention, a guide plate 11 is connected to the outer cavity of the stirring shaft 2 through a mounting rod 10, and the guide plate 11 is located above the stirring plate 6; small holes are evenly distributed on the guide plate 11, and the guide plate 11 is distributed at equal angles on the outer side of the stirring shaft 2, and the guide plate 11 is arranged downwardly from the outside to the inside;

[0038] As stirring proceeds, the internal pH is adjusted by adding buffer solution, and the reaction solution is introduced onto the guide plate 11. As the guide plate 11 rotates, the small holes thereon are used to evenly distribute the solution. At the same time, with its inclined structure, under the action of centrifugal force, the solution can gradually spread from the inside to the outside, and most of it will not be thrown to the peripheral area.

[0039] As an embodiment of the present invention, the angle adjustment assembly is arranged between the elastic telescopic rod 4 and the mounting rod 10, for adjusting the angle of the guide plate 11; the angle adjustment assembly includes a rack 121, the rack 121 is embedded in the stirring shaft 2 and slides vertically, and a push head 122 is provided at the bottom of the rack 121, and the push head 122 is fixed to the outer end telescopic part of the elastic telescopic rod 4, and a tooth roller 123 is engaged on the inner side of the rack 121, and the tooth roller 123 drives the mounting rod 10 to rotate in the stirring shaft 2 through a torsion spring, and a sealing plate 124 is fixed in the middle of the mounting rod 10, and the sealing plate 124 is fitted and slidably installed in the side cavity of the stirring shaft 2; the outer side of the top of the pushing head 122 is set to an inclined structure, and when the pushing head 122 moves outward, the rack 121 is pushed upward, and the sealing plate 124 is designed as an arc structure, and the moving trajectory of the sealing plate 124 corresponds to the tooth roller 123;

[0040] As the centrifugal force increases, the telescopic portion of the elastic telescopic rod 4 moves outward, and the inclined surface of the push head 122 contacts the rack 121, driving the rack 121 to move upward, and then the rotation of the gear roller 123 drives the mounting rod 10 and the guide plate 11 to rotate, adjusting their inclination angle.

[0041] As an embodiment of the present invention, a resistance adjustment assembly is provided in the stirring shaft 2 for adjusting the initial length of the elastic telescopic rod 4;

[0042] The resistance adjustment assembly includes a screw 131, which is sealed and penetrated at the bottom of the mixing tank 1 and the stirring shaft 2. An adjustment rod 132 is threadedly sleeved on the screw 131. The adjustment rod 132 is slidingly arranged in the cavity at the bottom of the stirring shaft 2. An adjustment bar 133 is fixed to the outside of the adjustment rod 132. The top of the adjustment bar 133 is located in the adjustment groove 134. The adjustment groove 134 is provided at the bottom of the mounting plate 3. The top of the adjustment groove 134 is designed as a sloped structure. The adjustment groove 134 is driven inward by the upward movement of the adjustment bar 133.

[0043] According to the shear force requirements of the reaction solution, the screw 131 is rotated to drive the adjustment rod 132 to slide vertically at the bottom of the stirring shaft 2, thereby driving the adjustment bar 133 to move in the adjustment groove 134, driving the mounting plate 3 to move horizontally, and adjusting the initial elastic resistance of the elastic telescopic rod 4.

[0044] The method comprises the following steps:

[0045] S1: According to the concentration of the reaction solution, the initial position of the mounting plate 3 is adjusted by the resistance adjustment component to adjust the initial resistance of the elastic telescopic rod 4;

[0046] S2: Add the reaction materials into the mixing tank 1, and drive the stirring shaft 2 to rotate by the motor. During the reaction, the speed of the stirring shaft 2 is gradually increased. The centrifugal force is used to drive the stirring plate 6 to move outward by a corresponding distance and rotate by a corresponding angle to reduce the shear force.

[0047] S3: During the reaction, a buffer solution is added to the mixing tank 1 to adjust the pH value. The solution drips onto the rotating guide plate 11 for guidance and uniform distribution. The angle adjustment component is used to adjust the inclination angle of the guide plate 11 according to the rotation speed to prevent a large amount of solution from spilling around. During the entire reaction process, the internal temperature is adjusted in real time by the built-in temperature control mechanism.

[0048] Working principle: First, according to the shear force requirements of the reaction solution, rotate the screw 131 to drive the adjustment rod 132 to slide vertically at the bottom of the stirring shaft 2, and then drive the adjustment bar 133 to move in the adjustment groove 134, drive the mounting plate 3 to move horizontally, adjust the initial elastic resistance of the elastic telescopic rod 4, and then introduce the reaction material into the mixing tank 1, drive the stirring shaft 2 to rotate by the motor, and use the built-in temperature control mechanism to control the internal reaction temperature in real time. When the stirring shaft 2 rotates, it gradually adjusts the speed according to the reaction time. Under the action of centrifugal force, it overcomes part of the elastic resistance of the elastic telescopic rod 4, so that the mounting sleeve 5 moves outward. The stirring plate 6 is movable, driving the stirring plate 6 to move outward. In this process, the guide groove 71 and the guide head 72 are conducted, so that the mounting sleeve 5 rotates on the inner shaft 7, and then the stirring plate 6 is moved laterally and rotated synchronously, and the connecting rod 8 and the inner plate 9 are driven to rotate on the inner shaft 7. On the one hand, the lateral position of the stirring plate 6 is adjusted, and on the other hand, the inclination angle of the stirring plate 6 is adjusted, so that when the speed is higher, the stirring plate 6 is closer to the inner wall of the mixing tank 1, and the angle of the stirring plate 6 is more horizontal. Furthermore, the overlap degree of the shear holes 91 on the stirring plate 6 and the inner plate 9 is higher, that is, the faster the speed, the lower the shear force, which effectively ensures the reaction effect;

[0049] As the stirring proceeds, the internal pH is adjusted by adding a buffer solution, and the reaction solution is introduced onto the guide plate 11. As the guide plate 11 rotates, the small holes thereon cooperate to evenly distribute the solution. At the same time, with its inclined structure, under the action of centrifugal force, the solution can gradually spread from the inside to the outside, and most of it will not be thrown to the peripheral area. As the centrifugal force increases, the telescopic part of the elastic telescopic rod 4 moves outward, and the inclined surface of the push head 122 contacts the rack 121, driving the rack 121 to move upward, and then the rotation of the toothed roller 123 drives the mounting rod 10 and the guide plate 11 to rotate, adjust its inclination angle, and seal the opening with the sealing plate 124 to prevent material from entering.
