Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and in particular to a glyphosate isopropylamine salt soluble agent synthesis device. Background Technology

[0002] Glyphosate isopropylamine salt is a widely used herbicide. During the synthesis of its soluble form, the reactants need to be thoroughly and uniformly mixed to ensure a smooth reaction and stable product quality.

[0003] However, existing stirring devices typically use stirring blades with a fixed angle, resulting in a fixed stirring flow field. This makes it difficult to optimize the fluid characteristics for different stages of the reaction (such as initial feeding and mixing, mid-reaction, and late-reaction homogenization). When the viscosity of the material changes, the fixed-angle stirring blades may not be able to simultaneously handle shear force and circulation flow, leading to low mixing efficiency, uneven reaction, and affecting product yield and quality. Therefore, a glyphosate isopropylamine salt soluble agent synthesis device is needed. Utility Model Content

[0004] The purpose of this invention is to provide a glyphosate isopropylamine salt soluble solvent synthesis device, which solves the problem in the prior art that the stirring blade angle cannot be adjusted to stir fluids of different concentrations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a glyphosate isopropylamine salt soluble solvent synthesis device, comprising a support, a reaction vessel, a cover plate, working components, a docking pipe, and a discharge pipe, wherein a solenoid valve is installed inside the discharge pipe.

[0006] The working components include a drive motor, a sleeve shaft, a connecting disc, a connecting rod, a rotating rod, and at least one stirring component;

[0007] The drive motor is fixed to the cover plate, and its output end is fixedly connected to the top end of the sleeve shaft;

[0008] The connecting plate is fixedly sleeved on the outer wall of the sleeve shaft, and at least one pair of connecting rods are connected to the bottom surface of the connecting plate;

[0009] The rotating rod is installed on the bottom inner wall of the sleeve shaft, and the stirring assembly is installed on the outer wall of the rotating rod;

[0010] The stirring assembly includes a second motor, a first gear, a second gear, a drive wheel, a stirring impeller, and a connecting base;

[0011] The second motor is fixed to the outer wall of the sleeve shaft and located above the cover plate;

[0012] The output end of the second motor is fixedly connected to the first gear, the first gear meshes with the second gear, and the second gear is rotatably sleeved on the outer wall of the sleeve shaft via a bearing;

[0013] The drive wheel is fixedly sleeved below the second gear, or is integrally formed with the second gear;

[0014] The connecting base is fixedly connected to the end of the connecting rod;

[0015] The stirring impeller is rotatably mounted inside the connecting base, and an extended soft sleeve is provided at the connection between the stirring impeller and the connecting base;

[0016] The connecting base includes a driven wheel and a fixed disk. The driven wheel is fixedly connected to the shaft of the stirring impeller and housed in the fixed disk. A stirring rod is fixedly connected to the side of the fixed disk away from the driving wheel.

[0017] The driving wheel meshes with the driven wheel to drive the stirring rod to rotate relative to the connecting base, thereby adjusting its tilt angle.

[0018] Preferably, the stirring rod has an internal hollow structure, with turbulence columns fixedly installed on its upper and lower surfaces, and an outlet and an inlet.

[0019] Preferably, the fixed disk has an annular groove inside that cooperates with the driven wheel.

[0020] Preferably, the second motor, the first gear, and the second gear are covered by a protective cover.

[0021] Preferably, the cover plate includes a lid, the side wall of which has a fixing hole, and the bottom surface has an annular groove that matches the port of the reactor.

[0022] Preferably, the turbulence columns are staggered on the upper and lower surfaces of the stirring rod.

[0023] Preferably, the extended sleeve is made of rubber or silicone material.

[0024] Preferably, the working component includes two stirring components, and the tilt angle of the stirring rods of the two stirring components can be adjusted independently.

[0025] Compared with the prior art, the beneficial effects of this utility model are:

[0026] 1. Achieved dynamic and precise optimization of the stirring flow field: The tilt angle of the stirring rod can be steplessly adjusted by the gear set driven by the second motor meshing with the driven wheel. This allows the device to dynamically adjust the ratio of the radial and axial forces of the stirring according to the material characteristics at different stages of the reaction, thereby achieving optimized switching from high-shear mixing to high-flow-rate circulation, significantly improving mixing efficiency and reaction uniformity.

[0027] 2. Ensures absolute reliability and stability of the working process: A second motor with a power-off self-locking function is used, which can firmly lock the stirring rod after angle adjustment. This self-locking torque is effectively transmitted through the transmission chain, ensuring that the stirring rod can resist strong fluid reaction forces and maintain the set angle during high-speed revolution and stirring. This fundamentally solves the technical problem of angle drift in adjustable stirring blades during operation, guaranteeing process reproducibility and product consistency.

[0028] 3. Enhanced temperature control during the reaction process: By incorporating flow channels within the hollow stirring rod and installing turbulence-inducing columns, the stirring and heat exchange functions are efficiently integrated. This not only increases the heat transfer area, but the turbulence-inducing columns also disrupt the fluid boundary layer, significantly enhancing heat transfer efficiency. This enables rapid and precise balancing of the heat in the reaction system, which is crucial for maintaining the optimal reaction temperature for glyphosate isopropylamine salt synthesis and preventing localized overheating or incomplete reaction.

[0029] 4. The structure is reasonable and eliminates internal contradictions: The angle adjustment transmission system is set on a fixed connecting base and connected to the main drive system through a connecting rod. The structure is clear and reasonable, which solves the contradictions in the transmission logic and improves the reliability and maintainability of the device. Attached Figure Description

[0036] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0037] This utility model relates to a soluble synthesis apparatus for glyphosate isopropylamine salt, such as... Figure 1-5 As shown, it mainly consists of a support frame 1, a reactor 2, a cover plate 3, working components 4, a docking pipe 5, and a discharge pipe 6. The reactor 2 is fixedly supported by the support frame 1. The cover plate 3 is tightly bolted to the top opening of the reactor 2. The discharge pipe 6 is located at the bottom of the reactor 2, and a solenoid valve 7 is installed inside it to control the discharge of the synthesized product. The docking pipe 5 can be used to add raw materials or connect other auxiliary equipment.

[0038] Furthermore, the core of this utility model lies in the working component 4. For example... Figure 3 As shown, the working component 4 includes a drive motor 41, a sleeve shaft 42, a connecting plate 43, a connecting rod 44, and two symmetrically arranged stirring components 46;

[0039] The drive motor 41 is fixedly installed at the center of the cover plate 3, and its output shaft is fixedly connected downward to the top of the sleeve shaft 42 via a coupling. The sleeve shaft 42 is a hollow shaft, and a disc-shaped connecting plate 43 is fixedly fitted on its lower outer wall. A pair of connecting rods 44 are symmetrically connected to the bottom sides of the connecting plate 43 by bolts.

[0040] The connecting base 466 of the stirring assembly 46 is fixedly connected to the end of the connecting rod 44 via a flange. Thus, the stirring assembly 46 is suspended below the connecting plate 43 via the connecting rod 44, and its overall position is fixed, without rotation, but it can revolve together with the sleeve shaft 42 and the connecting plate 43.

[0041] Among them, such as Figure 4 As shown, each stirring assembly 46 includes a second motor 461, a first gear 462, a second gear 463, a drive wheel 464, a stirring impeller 465, and a connecting base 466;

[0042] The second motor 461 is directly fixed to the top of the connecting base 466 via a mounting bracket. The first gear 462 is fixedly connected to the output shaft of the second motor 461. The second gear 463 is rotatably mounted inside the connecting base 466 via bearings and is always meshed with the first gear 462. The driving wheel 464 is coaxially fixed with the second gear 463 and can rotate synchronously with the second gear 463.

[0043] In particular, as a key preferred embodiment of this invention, the second motor 461 is a motor with a power-off self-locking function (such as a servo motor or stepper motor with an electromagnetic brake). This ensures that when the motor is powered off, its output shaft can be firmly locked and cannot be rotated by external force.

[0044] The stirring impeller 465 is rotatably mounted in the internal cavity of the connecting base 466 via a rotating shaft and bearings. At the sealing point of the rotating shaft, an extended soft sleeve made of rubber or silicone is provided. This soft sleeve can elastically deform as the angle of the stirring impeller 465 is adjusted, ensuring a dynamic seal at all times.

[0045] The connecting base 466 contains a driven wheel 4661, which is fixedly connected to the shaft of the stirring impeller 465. The lower part of the connecting base 466 is a fixed disk 4662, which has an annular groove that mates with the driven wheel 4661, allowing the driven wheel 4661 to rotate freely within a certain angle range. A stirring rod 4663 is fixedly connected to the bottom of the fixed disk 4662.

[0046] When it is necessary to adjust the stirring angle of a certain stirring component 46, the corresponding second motor 461 is activated. The second motor 461 drives the first gear 462 to rotate, and the first gear 462 drives the second gear 463, which meshes with it, to rotate, thereby driving the driving wheel 464 to rotate. The driving wheel 464 meshes with the driven wheel 4661, thereby driving the driven wheel 4661 to rotate. The driven wheel 4661 drives the stirring impeller 465 and the entire stirring rod 4663, which are fixed to it, to rotate around their own axis within the connecting base 466, thereby realizing stepless adjustment of the tilt angle of the stirring rod 4663;

[0047] After adjustment, the second motor 461 is turned off. At this point, the power-off self-locking function of the second motor 461 immediately takes effect, locking its output shaft. This locking torque is transmitted to the driven wheel 4661 through the first gear 462, the second gear 463, and the driving wheel 464, ultimately securing the angle of the stirring rod 4663 firmly at the set position. This ensures that during subsequent high-speed revolution stirring driven by the drive motor 41, the stirring rod 4663 will not change its angle due to the enormous fluid reaction force, guaranteeing the stability of the flow field and the reliability of the process.

[0048] Furthermore, such as Figure 5 As shown, the stirring rod 4663 in this embodiment is a hollow metal tube. Multiple staggered turbulence columns 46631 are welded to its upper and lower surfaces to disperse the fluid during stirring, generating more complex turbulence and improving mixing efficiency. The stirring rod 4663 has an inlet 46633 at the top and an outlet 46632 at the bottom. During the synthesis process, heat transfer oil can be pumped in through the inlet 46633 via an external circulation system, flowing through the hollow stirring rod 4663 and then out through the outlet 46632, thereby effectively exchanging heat with the mixture in the reactor 2 and precisely controlling the reaction temperature.

[0049] Furthermore, such as Figure 2 As shown, the cover plate 3 has multiple evenly spaced fixing holes 32 along its edge. During installation, bolts are passed through these fixing holes 32 and tightened into the threaded holes on the top flange of the reactor 2, thereby securely locking the cover plate 3 onto the reactor 2. An annular groove, or annular groove 33, is machined on the bottom surface of the cover plate 31. An O-ring seal is placed within this annular groove 33. When the cover plate 3 is locked, the O-ring seal is pressed against the port plane of the reactor 2, forming a reliable seal.

[0050] In practical use: The main drive motor 41 drives the sleeve shaft 42 and connecting plate 43 to rotate, and the connecting rod 44 drives all the stirring components 46 to revolve, performing basic stirring of the reagents in the reactor 2. By starting the corresponding second motor 461, the driven wheel 4661 is driven by the first gear 462, the second gear 463 and the driving wheel 464 to drive the driven wheel 4661 to drive the stirring rod 4663 to deflect within the connecting base 466, thereby changing the tilt angle to adapt to the needs of different mixing stages. After adjustment, the second motor 461 with self-locking function will lock immediately to ensure that the angle remains stable during high-speed stirring. The hollow stirring rod 4663 can be filled with heat exchange medium through the inlet 46633 and discharged through the outlet 46632, realizing the simultaneous operation of stirring and temperature control, which significantly improves the synthesis efficiency and quality.
