Description

Technical Field

[0001] This utility model relates to the field of mixing device technology, and in particular to a stirring and mixing device for NMN ethanol-free crystallization solution. Background Technology

[0002] NMN is a naturally occurring bioactive nucleotide with the chemical formula C11H15N2O8P. It is a key intermediate in the synthesis of coenzyme I (NAD+) and is widely found in the human body, vegetables, fruits, and meats, such as avocados and edamame. NMN can be prepared through chemical synthesis and biological methods. It is widely used in pharmaceuticals, medicine, cosmetic raw materials, and food additives, and has anti-aging and metabolism-improving effects. The NMN molecule contains a pyrimidine ring and a phosphate ester bond. When the angle (A) between the stirring blade and the horizontal plane is too large, a large shear force will be generated during stirring, which will destroy the NMN molecules in the solution. For example, a 90° blade is like a vertical wall. When the fluid hits it, it will generate violent turbulence. This instantaneous impact force far exceeds the molecular bond energy. High shear force leads to molecular chain breakage (degradation rate > 0.5% affects purity). The more crystals in the NMN non-ethanol crystallization solution, the stronger the shear resistance.

[0003] In the prior art, there is a solution crystallization stirred tank (publication number: CN213824473U). This device uses double stirring to make the stirring gap smaller, so that the material is stirred more thoroughly, has better uniformity, and is less likely to cause material sedimentation and wall adhesion.

[0004] However, this patent has some drawbacks in use, such as: the tilt angle of the propulsion blades in the device is fixed. When there are fewer crystals in the NMN ethanol-free crystallization solution, its shear resistance is weaker. Consequently, the fixed-angle stirring blades will destroy some NMN molecules and reduce the purity of the solution. In view of this, we propose an NMN ethanol-free crystallization solution stirring and mixing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stirring and mixing device for NMN ethanol-free crystallization solutions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A stirring and mixing device for NMN ethanol-free crystallization solution, comprising:

[0008] A base, on the surface of which a mixing cylinder is mounted, the mixing cylinder being used to hold an NMN ethanol-free crystallization solution;

[0009] The first shaft is driven to rotate inside the mixing cylinder. The surface of the first shaft is provided with a plurality of stirring blades with an inclination angle A relative to the horizontal plane. The inclination angle A is adjustable and the adjustment range is 20° to 50°.

[0010] The first transmission mechanism is used to drive the first shaft to rotate, thereby causing the stirring blades to rotate circumferentially in the mixing cylinder to stir the solution. The first transmission mechanism is equipped with a torque sensor.

[0011] The second transmission mechanism adjusts the tilt angle A of the stirring blade in real time according to the change of the detection value of the torque sensor. The smaller the torque value, the smaller the tilt angle A, and vice versa.

[0012] Preferably, the mixing cylinder has a first through hole at the top, the first shaft is rotatably installed in the first through hole, the first through hole is surrounded by a first protrusion with an annular structure, a layer plate is fixedly installed in the first protrusion, and a dust cover is detachably attached around the first protrusion.

[0015] Preferably, the first transmission mechanism includes:

[0016] The first gear is rotatably mounted on the top of the mixing cylinder;

[0017] The second gear is fixedly installed on the top of the first shaft, and the second gear meshes with the first gear.

[0018] Preferably, the second transmission mechanism includes:

[0019] Two active bevel gears are symmetrically arranged, one of which is rotatably mounted in the first groove and the other is rotatably mounted on the surface of the first block.

[0020] Driven bevel gears, wherein multiple driven bevel gears are provided and all are rotatably mounted in the first groove, and the driven bevel gears are used to drive the third shaft to rotate;

[0021] The second shaft is used to drive the rotation of the drive bevel gear.

[0022] Preferably, the top end of the first shaft has a channel communicating with the first groove, the diameter of the channel is larger than the diameter of the second shaft, and one end of the second shaft passes through the channel and is fixedly connected to the rotation center of the active bevel gear.

[0023] Preferably, the multiple driven bevel gears are fixedly connected to the rotation centers of multiple third shafts, and the multiple driven bevel gears simultaneously mesh with two driving bevel gears.

[0024] Preferably, a first motor and a second motor are fixedly installed on the top of the shelf, the first motor is used to drive the first gear to rotate, and the second motor is used to drive the second shaft to rotate.

[0025] Preferably, the output end of the first motor is connected to the rotation center of the first gear, the torque sensor is connected in series between the first motor and the first gear to monitor the change of torque at the output end of the first motor in real time, and the output end of the second motor is connected to the rotation center of one end of the second shaft.

[0026] Compared with the prior art, in the process of stirring the NMN ethanol-free crystallization solution, when the crystals are not completely dissolved, the NMN molecules in the solution are not widely dispersed and have strong shear resistance. Therefore, the solution can be stirred with a stirring blade at a larger tilt angle A (adjusted by the second transmission mechanism) to accelerate the dissolution rate of the crystals. When the crystals are completely dissolved, the second transmission mechanism adjusts the tilt angle A of the stirring blade to a smaller value, thereby avoiding damage to the NMN molecules in the solution during the stirring process and improving the purity of the mixed solution.

[0038] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0039] like Figure 3 As shown, this embodiment provides a stirring and mixing device for NMN ethanol-free crystallization solution, including: a base 200, a first shaft 300, a first transmission mechanism, and a second transmission mechanism. A mixing cylinder 100 is mounted on the surface of the base 200. The mixing cylinder 100 is used to hold the NMN ethanol-free crystallization solution. The first shaft 300 can be driven to rotate inside the mixing cylinder 100. The surface of the first shaft 300 is provided with multiple stirring blades 310 with an inclination angle A relative to the horizontal plane. The inclination angle A is adjustable, and the adjustment range is 20° to 50°. The first transmission mechanism is used to drive the first shaft 300 to rotate, thereby driving the stirring blades 310 to rotate circumferentially inside the mixing cylinder 100 to stir the solution. A torque sensor 700 is provided in the first transmission mechanism. The second transmission mechanism adjusts the inclination angle A of the stirring blades 310 in real time according to the change of the detection value of the torque sensor 700. The smaller the torque value, the smaller the inclination angle A, and vice versa.

[0040] With the above settings, when stirring an NMN solution without ethanol crystallization, if the crystals are not completely dissolved, the stirring blade 310 experiences greater resistance than when the crystals are dissolved. This is detected by the torque sensor 700 in the first transmission mechanism. When the crystals are not dissolved, the NMN molecules in the solution are not widely dispersed and have strong shear resistance. Therefore, the stirring blade 310 with a larger tilt angle A can be used to stir the solution (adjusted by the second transmission mechanism) to accelerate the dissolution rate of the crystals. When the torque value decreases, the NMN molecules in the solution are more dispersed and are easily destroyed by the high-shear stirring blade 310. At this time, the second transmission mechanism reduces the tilt angle A of the stirring blade 310 to avoid destroying the NMN molecules in the solution during stirring, thereby improving the purity of the mixed solution.

[0041] In specific implementation methods, such as Figure 2 As shown, the mixing cylinder 100 has a first through hole 101 at its top. The first shaft 300 is rotatably installed in the first through hole 101. The first through hole 101 is surrounded by a first protrusion 102 in an annular structure. A shelf 110 is fixedly installed inside the first protrusion 102. A dust cover 120 is detachably attached to the first protrusion 102. (See Figure 100) Figure 3 ),like Figure 5 As shown, the first shaft body 300 has a first groove 301 at its bottom end, and a first block 320 is detachably and fixedly installed in the first groove 301. The stirring blade 310 is provided with a third shaft body 311 and a stirring blade 312 (see...). Figure 4 The third shaft 311 is inserted into the first groove 301 at one end and is rotatably connected to the first shaft 300. The third shaft 311 is welded to the stirring plate 312 to form a whole. Each edge of the stirring plate 312 is chamfered to further reduce the damage to NMN molecules in the solution during the stirring process.

[0042] More specifically, such as Figure 6 As shown, the first transmission mechanism includes a first gear 800 and a second gear 900. The first gear 800 is rotatably mounted on the top of the mixing cylinder 100, and the second gear 900 is fixedly mounted on the top of the first shaft 300. The second gear 900 meshes with the first gear 800.

[0043] like Figure 4 and Figure 5 As shown, the second transmission mechanism includes:

[0044] The system includes a driving bevel gear 330, a driven bevel gear 340, and a second shaft 600. Two driving bevel gears 330 are symmetrically arranged. One of the two driving bevel gears 330 is rotatably mounted in the first groove 301, and the other is rotatably mounted on the surface of the first block 320. Multiple driven bevel gears 340 are provided and are all rotatably mounted in the first groove 301. The driven bevel gears 340 are used to drive the third shaft 311 to rotate, and the second shaft 600 is used to drive the driving bevel gears 330 to rotate.

[0045] like Figure 4 As shown, the top end of the first shaft 300 has a channel communicating with the first groove 301. The diameter of the channel is larger than the diameter of the second shaft 600. One end of the second shaft 600 passes through the channel and is fixedly connected to the rotation center of the driving bevel gear 330. Multiple driven bevel gears 340 are fixedly connected to the rotation centers of multiple third shafts 311 respectively. Multiple driven bevel gears 340 mesh with two driving bevel gears 330 at the same time.

[0046] Considering the gap between the helical gears and the need for a stable angle for stirring, the active bevel gear 330 located on the surface of the first block 320 is mainly used to provide support and stability for the driven bevel gear 340, so that it is in a stable state after the stirring blade 310 adjusts its angle, avoiding shaking due to the gap between the helical gears and improving the stability of the shear force output.

[0047] like Figure 3 As shown, a first motor 400 and a second motor 500 are fixedly installed on the top of the shelf 110. The first motor 400 is used to drive the first gear 800 to rotate, and the second motor 500 is used to drive the second shaft 600 to rotate.

[0048] More specifically, such as Figure 6 As shown, the output end of the first motor 400 is connected to the rotation center of the first gear 800. The torque sensor 700 is connected in series between the first motor 400 and the first gear 800 to monitor the change in torque at the output end of the first motor 400 in real time. The output end of the second motor 500 is connected to the rotation center of one end of the second shaft 600. A control terminal with a PLC control system is provided to receive the signal from the torque sensor 700 and convert it into a relevant electrical signal to control the rotation angle of the second motor 500.

[0049] Both the first motor 400 and the second motor 500 are servo motors with self-locking function.

[0050] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
