A reaction kettle for producing glyphosate isopropylamine salt aqueous solution

Abstract

This invention belongs to the field of reaction vessel technology and discloses a reaction vessel for the production of glyphosate isopropylamine salt solution. The reaction vessel includes a vessel body, a vessel cover mounted on the top of the vessel body, a drive mechanism mounted on the top of the vessel cover, and a transmission rod connected to the bottom of the drive mechanism. The transmission rod passes through the vessel cover and is inserted into the interior of the vessel body. Several stirring components are movably mounted on the outside of the transmission rod. Each stirring component includes a stirring rod mounted on the outside of the transmission rod, and several stirring blades are fitted around the stirring rod. Due to the adjustable components, the angle of the stirring blades can be adjusted in cooperation with the stirring rod and connecting components. Therefore, when the transmission rod drives the stirring components to rotate through the slider and connecting sleeve, the stirring blades can apply a certain thrust to the mixture, giving it a component force towards the axis of the transmission rod. This effectively counteracts the centrifugal force of the mixture, thereby ensuring thorough mixing of different materials.

Description

Technical Field

[0001] This invention belongs to the field of reaction vessel technology, specifically a reaction vessel for the production of glyphosate isopropylamine salt solution. Background Technology

[0002] Glyphosate is a systemic, chronic, broad-spectrum, non-selective herbicide that is effective in controlling annual and biennial monocotyledonous grasses and is very effective against perennial deep-rooted weeds. It mainly inhibits enolpyruvylshikimate phosphate synthase in plants, thereby inhibiting the conversion of shikimate to phenylalanine, tyrosine, and tryptophan, which interferes with protein synthesis and leads to plant death.

[0003] Reactors are pressure vessels widely used in the chemical industry to complete processes such as sulfidation, nitration, and hydrogenation. A reactor consists of a vessel body, vessel cover, jacket, agitator, transmission device, shaft sealing device, and support structure.

[0004] The production of glyphosate isopropylamine salt solution requires the use of a reaction vessel. During production, high-speed stirring is often required in the reaction vessel to ensure that various substances are fully mixed or reacted. However, centrifugal force is generated during rotational stirring, and centrifugal force is closely related to the density of substances. This causes substances with different densities to disperse into different layers due to centrifugal force, making them unable to mix well and thus reducing the efficiency of the mixing reaction. Therefore, it is necessary to develop a new type of reaction vessel that can effectively reduce the impact of centrifugal force. Summary of the Invention

[0005] (a) Technical problems to be solved To address the problems mentioned in the background art, the present invention provides a reaction vessel for the production of glyphosate isopropylamine salt solution, which has the advantages of good mixing effect and easy adjustment.

[0006] In this process, the angle of the stirring blade is adjusted by the cooperation of the stirring rod and the connecting assembly. When the transmission rod drives the stirring assembly to rotate through the slider and the connecting sleeve, the stirring blade can apply a certain thrust to the mixture, so that it has a component force on the side of the transmission rod axis, which can counteract centrifugal force and make the material fully mixed.

[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: a reaction vessel for producing glyphosate isopropylamine salt solution, comprising a vessel body, a vessel cover installed on the top of the vessel body, a driving mechanism installed on the top of the vessel cover, a transmission rod connected to the bottom of the driving mechanism, the transmission rod passing through the vessel cover and inside the vessel body, and several stirring components movably installed on the outside of the transmission rod; The stirring assembly includes a stirring rod installed on the outside of the transmission rod, a plurality of stirring blades are fitted on the outside of the stirring rod, a connecting component is provided inside the stirring blades, and an adjusting component is provided inside the stirring rod. The stirring blades are installed on the stirring rod through the connecting component, and the connecting component is connected to the adjusting component.

[0008] Preferably, the connecting assembly includes a positioning and limiting hole at the top of the stirring rod, and a positioning hole at the bottom of the stirring rod located below the positioning and limiting hole. A limiting gear and a positioning rod are respectively inserted into the positioning and limiting hole and the positioning hole.

[0009] Preferably, the upper end of the limiting gear passes through the positioning limiting hole and extends to the top of the stirring rod and is fixedly connected to the inner wall of the stirring plate. The lower end of the positioning rod passes through the positioning hole and the stirring plate. A positioning spring is provided on the outside of the positioning rod. The upper and lower ends of the positioning spring are respectively connected to the positioning rod and the inner wall of the stirring plate.

[0010] Preferably, the positioning rod is movably sleeved inside the stirring plate, and the distance between the stirring rod and the bottom of the inner cavity of the stirring plate is greater than the sum of the length of the upper end of the positioning rod inserted into the positioning hole and the length of the positioning spring after compression.

[0011] Preferably, the adjustment component includes a sliding limiting hole formed inside the stirring rod and on the side of the positioning limiting hole, the inner wall of the sliding limiting hole is smooth, and the interface of the sliding limiting hole is a non-circular structure.

[0012] Preferably, a toothed plate is slidably sleeved inside the sliding limiting hole, and a movable block is threaded inside the toothed plate. A connecting rod is fixedly connected to the side of the movable block away from the transmission rod, and the other end of the connecting rod away from the transmission rod passes through the sliding limiting hole and extends to the outside of the stirring rod and is fixedly connected to a knob.

[0013] Preferably, the toothed plate has a toothed groove on the side near the positioning and limiting hole, and the toothed groove meshes with the limiting gear.

[0014] Preferably, the driving mechanism includes a fixed frame that is fixedly installed on the top of the vessel lid, a drive motor is installed on the top of the inner cavity of the fixed frame, a transmission shaft is fixedly connected to the lower end of the output shaft of the drive motor, and the lower end of the transmission shaft is fixedly connected to a transmission rod.

[0015] Preferably, the transmission shaft has an adjustment port on its side, and an adjustment plate is rotatably sleeved inside the transmission shaft. The side of the adjustment plate has evenly distributed actuating plates.

[0016] Preferably, a lead screw is fixedly connected to the bottom of the adjusting plate and passes through the inside of the transmission rod. Several movable sleeves are movably sleeved inside the transmission rod, and the movable sleeves are threaded onto the outside of the lead screw. Several connecting sleeves are movably sleeved on the outside of the transmission rod, and the connecting sleeves correspond one-to-one with the movable sleeves. The end of the stirring rod near the transmission rod is fixedly connected to the connecting sleeve. A sliding groove is opened on the side of the transmission rod, and a slider is slidably engaged inside the sliding groove. The two sides of the slider are fixedly connected to the movable sleeve and the connecting sleeve, respectively.

[0017] (III) Beneficial Effects Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Due to the setting of the adjustment component, the angle of the stirring blade can be adjusted with the cooperation of the stirring rod and the connecting component. Thus, when the transmission rod drives the stirring component to rotate through the slider and the connecting sleeve, the stirring blade can apply a certain thrust to the mixture, so that it has a component force on the side of the transmission rod axis, which can effectively counteract the centrifugal force of the mixture, thereby making different materials fully mixed.

[0018] 2. Due to the design of the connecting component, the present invention allows workers to easily install the required number of stirring blades onto the stirring rod, while also controlling the density of the stirring blades as needed. Under the elastic force of the positioning spring, the connecting component can be continuously and stably connected to the stirring rod, ensuring the stability of the stirring blade installation. It also facilitates worker control and allows for easy disassembly of the stirring blades.

[0019] 3. Due to the screw setting, under the restriction of the sliding groove and slider on the movable sleeve and connecting sleeve, the screw can be rotated independently of the transmission rod by adjusting the adjusting plate through the adjusting port. In turn, the rotation of the screw can drive several stirring components to move up and down through the slider and connecting sleeve, thereby changing the range of the stirring components to suit the stirring of mixtures of different capacities.

[0020] 4. Because the thread density ratios of different movable sleeves and lead screws are different, and the thread density ratio gradually decreases linearly from top to bottom, the upper stirring component can move up and down at a speed greater than that of the lower stirring component. This allows the movement of several stirring components to gradually increase from bottom to top, thereby adapting to the height of mixtures of different capacities and improving the mixing effect.

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 7 As shown, the present invention provides a reaction vessel for the production of glyphosate isopropylamine salt solution, including a vessel body 1, a vessel cover 2 installed on the top of the vessel body 1, a drive mechanism installed on the top of the vessel cover 2, a transmission rod 3 connected to the bottom of the drive mechanism, the transmission rod 3 passing through the vessel cover 2 and inserted into the interior of the vessel body 1, and several stirring components 4 movably installed on the outside of the transmission rod 3. The mixing assembly 4 includes a mixing rod 41 installed on the outside of the transmission rod 3. Several mixing blades 42 are fitted on the outside of the mixing rod 41. A connecting assembly 43 is provided inside the mixing blades 42. An adjusting assembly 44 is provided inside the mixing rod 41. The mixing blades 42 are installed on the mixing rod 41 through the connecting assembly 43. The connecting assembly 43 is connected to the adjusting assembly 44. With the cooperation of the mixing rod 41 and the connecting assembly 43, the angle of the mixing blades 42 is adjusted. Thus, when the transmission rod 3 drives the mixing assembly 4 to rotate through the slider 13 and the connecting sleeve 12, the mixing blades 42 can apply a certain thrust to the mixture, so that it has a component force on the side of the transmission rod 3 axis, which can effectively counteract the centrifugal force of the mixture.

[0025] like Figure 6 and Figure 7 As shown, the connecting component 43 includes a positioning and limiting hole 431 opened at the top of the stirring rod 41, and a positioning hole 432 opened at the bottom of the stirring rod 41 below the positioning and limiting hole 431. A limiting gear 433 and a positioning rod 434 are respectively inserted into the positioning and limiting hole 431 and the positioning hole 432. Due to the setting of the connecting component 43, it is convenient for the operator to install the required number of stirring blades 42 onto the stirring rod 41, and at the same time, the density of the stirring blades 42 can be controlled as required.

[0026] like Figure 6 As shown, the upper end of the limiting gear 433 passes through the positioning limiting hole 431 and extends to the top of the stirring rod 41 and is fixedly connected to the inner wall of the stirring plate 42. The lower end of the positioning rod 434 passes through the positioning hole 432 and the stirring plate 42. A positioning spring 435 is provided on the outside of the positioning rod 434. The upper and lower ends of the positioning spring 435 are respectively connected to the positioning rod 434 and the inner wall of the stirring plate 42. Under the elastic force of the positioning spring 435, the connecting component 43 can be continuously and stably connected to the stirring rod 41 to ensure the installation stability of the stirring plate 42. At the same time, it is also convenient for the staff to control and disassemble the stirring plate 42.

[0027] like Figure 6 As shown, the positioning rod 434 is movably sleeved inside the stirring plate 42. The distance between the stirring rod 41 and the bottom of the inner cavity of the stirring plate 42 is greater than the sum of the length of the upper end of the positioning rod 434 inserted into the positioning hole 432 and the length of the positioning spring 435 after compression.

[0028] like Figure 7 As shown, the adjustment component 44 includes a sliding limiting hole 441 opened inside the stirring rod 41 and on the side of the positioning limiting hole 431. The inner wall of the sliding limiting hole 441 is smooth, and the interface of the sliding limiting hole 441 is a non-circular structure.

[0029] like Figure 7 As shown, a toothed plate 442 is slidably sleeved inside the sliding limiting hole 441, and a movable block 443 is threadedly sleeved inside the toothed plate 442. A connecting rod 444 is fixedly connected to the side of the movable block 443 away from the transmission rod 3. The other end of the connecting rod 444 away from the transmission rod 3 passes through the sliding limiting hole 441 and extends to the outside of the stirring rod 41, and is fixedly connected to a knob 445. Due to the setting of the movable block 443, under the restriction of the toothed plate 442 by the sliding limiting hole 441, when the movable block 443 is rotated by the knob 445 and the connecting rod 444, the toothed plate 442 can move along the inside of the sliding limiting hole 441, and thus drive several limiting gears 433 to rotate through its side tooth grooves.

[0030] like Figure 7As shown, the toothed plate 442 has a toothed groove on the side near the positioning and limiting hole 431, and the toothed groove meshes with the limiting gear 433. Due to the setting of the toothed groove, the toothed plate 442 can drive several limiting gears 433 to rotate at the same time, and can achieve the effect of controlling the synchronous adjustment of the angle of several stirring plates 42.

[0031] like Figure 3 As shown, the driving mechanism includes a fixed frame 5 fixedly installed on the top of the vessel lid 2. A drive motor 6 is installed on the top of the inner cavity of the fixed frame 5. A transmission shaft 7 is fixedly connected to the lower end of the output shaft of the drive motor 6. The lower end of the transmission shaft 7 is fixedly connected to the transmission rod 3.

[0032] like Figure 3 As shown, an adjustment port 14 is provided on the side of the transmission shaft 7, and an adjustment plate 8 is rotatably sleeved inside the transmission shaft 7. The side of the adjustment plate 8 has evenly distributed actuating plates. The adjustment port 14 allows the operator to easily operate the adjustment plate 8. By turning the adjustment plate 8, the lead screw 9 can rotate independently of the transmission rod 3, thereby controlling the movement of the movable sleeve 11 and other structures.

[0033] like Figure 4 As shown, a lead screw 9 is fixedly connected to the bottom of the adjusting plate 8 and passes through the inside of the transmission rod 3. Several movable sleeves 11 are movably sleeved inside the transmission rod 3 and threaded onto the outside of the lead screw 9. Several connecting sleeves 12 are movably sleeved on the outside of the transmission rod 3, and the connecting sleeves 12 correspond one-to-one with the movable sleeves 11. The end of the stirring rod 41 near the transmission rod 3 is fixedly connected to the connecting sleeve 12. A sliding groove 10 is opened on the side of the transmission rod 3. A slider 13 is slidably engaged inside the sliding groove 10. The two sides of the slider 13 are fixedly connected to the movable sleeves 11 and the connecting sleeves 12, respectively. Under the restriction of the sliding groove 10 and the slider 13 on the movable sleeves 11 and the connecting sleeves 12, the rotation of the lead screw 9 can cause the movable sleeves 11 to drive several stirring components 4 to move up and down through the sliders 13 and the connecting sleeves 12, thereby changing the range of the stirring components 4 to suit the stirring of mixtures of different capacities.

[0034] Working principle and usage process of this invention: Open the observation window on the side of the vessel body 1 and adjust the stirring assembly 4. Adjust the number, installation density and installation angle of the stirring blades 42 according to the stirring process requirements. That is, install the required number of stirring blades 42 onto the stirring rod 41 through the connecting assembly 43 and control the installation density. Then adjust the angle of several stirring blades 42 on the stirring rod 41 through the adjusting assembly 44. When installing the stirring plate 42, first pull down the positioning rod 434 so that its upper end falls completely into the stirring plate 42. Then, the stirring plate 42 can be fitted onto the stirring rod 41. After inserting the limiting gear 433 into the positioning limiting hole 431, release the positioning rod 434. Under the elastic force of the positioning spring 435, the upper end of the positioning rod 434 can be inserted into the positioning hole 432. When adjusting the angle of the stirring blade 42, first turn the knob 445 to drive the movable block 443 to rotate through the connecting rod 444. The rotation of the movable block 443 can be restricted by the sliding limit hole 441 on the toothed plate 442, so that when the movable block 443 rotates, it drives the toothed plate 442 to move along the inside of the sliding limit hole 441, thereby driving the limit gear 433 to rotate, which will make the stirring blade 42 rotate. By adjusting the adjustment plate 8 through the adjustment port 14, the lead screw 9 can be rotated. Since the movable sleeve 11 and the connecting sleeve 12 are restricted by the slide groove 10 and the slider 13, the rotation of the lead screw 9 can drive the movable sleeve 11 to move up and down. In turn, the slider 13 and the connecting sleeve 12 drive the stirring assembly 4 to move up and down as a whole. Since the thread density ratio between different movable sleeves 11 and lead screw 9 is different, the upward movement rate of different connecting sleeves 12 can be different.
