Description

Technical Field

[0001] This utility model relates to the field of pressure synthesis reactor technology, specifically a pressure synthesis reactor. Background Technology

[0002] The main production process of glyphosate technical grade by the glycine method involves using methanol as a solvent, triethylamine as a catalyst, and raw materials such as paraformaldehyde (or polymer liquid), glycine, and dimethyl phosphite in a reaction vessel. Following specific process ratios and controlled time and temperature, the reaction proceeds through paraformaldehyde depolymerization (the polymer liquid is the solution after the depolymerization reaction), glycine addition, and dimethyl phosphite condensation to generate a synthetic liquid. This liquid then undergoes a series of processes including acid hydrolysis, alcohol removal, and crystallization to finally obtain glyphosate technical grade. The synthesis vessel, as the first step in the entire glyphosate production process, plays a crucial role in the overall production process and the final yield of the glyphosate product.

[0003] In the existing process of pressurized synthesis of glycine, solid raw materials need to be added. Unreacted solids tend to accumulate at the bottom of the pressurized synthesis vessel, clogging the bottom valve. Furthermore, when the stirring rod is stirring, the solid material will also gather at the center of the bottom of the pressurized synthesis vessel with the rotation of the water flow, making it difficult to evenly distribute the solid raw materials throughout the pressurized synthesis vessel. At the same time, the solid raw materials tend to adhere to the inner wall of the feeding pipe when being added, making them difficult to clean. Utility Model Content

[0004] The purpose of this invention is to provide a pressurized synthesis reactor to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A pressure synthesis reactor includes a pressure synthesis reactor with a stirring assembly movably disposed inside. The stirring assembly includes a hollow rod that rotatably penetrates the pressure synthesis reactor. A reciprocating screw is fixedly installed on the lower surface of the hollow rod. A sliding sleeve is screwed onto the outer surface of the reciprocating screw. Multiple material bowls are fixedly installed at equal angles on the outer surface of the sliding sleeve. A feeding assembly is fixedly installed on the upper surface of the pressure synthesis reactor. The feeding assembly includes a hopper fixedly installed on the upper surface of the pressure synthesis reactor by a bracket. A spiral feeding rod is rotatably connected inside the hopper. A first annular tube is fixedly installed on the upper surface inside the hopper.

[0007] Furthermore, a heat exchange tube is fixedly installed inside the pressurized synthesis reactor, and a discharge pipe is fixedly embedded in the lower surface of the pressurized synthesis reactor.

[0008] Furthermore, the hollow rod has multiple through holes equidistantly opened on its outer surface, and multiple stirring blades are fixedly installed equidistantly on its outer surface. A No. 1 motor is fixedly installed on the upper surface of the pressurized synthesis reactor via a bracket. Gears are fixedly installed on both the output end of the No. 1 motor and the outer surface of the hollow rod, and the two gears are movably meshed and connected.

[0009] Furthermore, a slide is fixedly installed on the lower inner surface of the pressurized synthesis reactor outside the reciprocating screw. The slide passes through multiple material bowls and is slidably connected to the material bowls.

[0010] Furthermore, the upper end of the hollow rod passes through the hopper and is rotatably connected to the hopper. A second motor is fixedly installed on the upper surface of the hopper, and the output end of the second motor is fixedly connected to the screw feed rod.

[0011] Furthermore, a feed pipe is fixedly embedded in the upper surface of the hopper, an air inlet pipe is fixedly embedded in the upper surface of the hopper, an air pipe is provided inside the hollow rod, and the upper end of the air pipe is fixedly connected to the air inlet pipe.

[0012] Furthermore, a second annular pipe is fixedly installed on the upper surface inside the silo. The first and second annular pipes are fixedly connected by a pipe. Multiple nozzles are fixedly installed at equal intervals on the outer surfaces of the first and second annular pipes. One end of the first annular pipe is fixedly inserted through the upper surface of the silo.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The operation of motor No. 1 causes the hollow rod and reciprocating screw to rotate, which in turn causes multiple feed bowls to move up and down synchronously with the sliding sleeve. When moving upward, the feed bowls scoop up the solution, causing the remaining solution to gather below the feed bowls in the pressure synthesis reactor. This pushes the solid raw materials at the bottom of the pressure synthesis reactor to move. When the feed bowls move downward, they push the solution downward, which in turn pushes the solid raw materials to move. Thus, the rotation of the hollow rod drives the feed bowls to move up and down, causing the solution to flow at the bottom of the pressure synthesis reactor. This pushes the solid raw materials gathered at the center of the bottom of the pressure synthesis reactor to move outward, preventing the solid raw materials from depositing at the bottom of the pressure synthesis reactor and clogging the bottom valve. At the same time, it facilitates the even distribution of the solid raw materials throughout the pressure synthesis reactor, accelerating the reaction rate.

[0015] 2. Solid raw materials are fed in through the feed pipe. Motor No. 2 runs, driving the screw feeder to rotate, which helps the solid raw materials to enter the hollow rod. This provides a moving force to the solid raw materials, making it easier for them to be discharged from the through hole. This allows the solid raw materials to be evenly transported into the solution inside the pressurized synthesis reactor, thus accelerating the reaction rate.

[0016] 3. Liquid raw materials are conveyed into the No. 1 and No. 2 annular pipes and discharged from multiple nozzles. The sprayed liquid raw materials wash the inner wall of the hopper and the spiral feeding rod, and wash away the solid raw materials adhering to their surfaces. This makes it easier to clean the inner wall of the solid raw material feeding pipe through the liquid raw materials, reducing the difficulty of cleaning. At the same time, the liquid raw materials react with the solid raw materials during feeding, preventing the solid raw materials from clogging the hollow rod and speeding up the feeding speed.

[0022] 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.

[0023] Please see Figures 1-4In this embodiment of the present invention, a pressurized synthesis reactor includes a pressurized synthesis reactor 1. A heat exchange tube 101 is fixedly installed inside the pressurized synthesis reactor 1. A discharge pipe 102 is fixedly embedded in the lower surface of the pressurized synthesis reactor 1. A stirring assembly 2 is movably installed inside the pressurized synthesis reactor 1. The stirring assembly 2 includes a hollow rod 201 that rotatably penetrates the pressurized synthesis reactor 1. A reciprocating screw 204 is fixedly installed on the lower surface of the hollow rod 201. A sliding sleeve 205 is screwed onto the outer surface of the reciprocating screw 204. Multiple material bowls 206 are fixedly installed at equal angles on the outer surface of the sliding sleeve 205. A feeding assembly 3 is fixedly installed on the upper surface of the pressurized synthesis reactor 1. The feeding assembly 3 includes a hopper 301 fixedly installed on the upper surface of the pressurized synthesis reactor 1 by a bracket. A spiral feeding rod 305 is rotatably connected inside the hopper 301. A first annular pipe 302 is fixedly installed on the upper surface inside the hopper 301.

[0024] Specifically, the solution inside the pressurized synthesis vessel 1 is stirred by the stirring component 2, and the solution at the bottom of the pressurized synthesis vessel 1 is agitated to make it flow and prevent solids from accumulating there. Then, the solid and liquid raw materials are fed at the same time by the feeding component 3, and the liquid raw materials are flushed over the solid raw materials to prevent solid raw materials from remaining inside the hopper 301.

[0025] Example 1

[0026] like Figure 2 and Figure 4 As shown, in this embodiment, a plurality of through holes 202 are equidistantly opened on the outer surface of the hollow rod 201, and a plurality of stirring blades 203 are fixedly installed equidistantly on the outer surface of the hollow rod 201. A No. 1 motor 208 is fixedly installed on the upper surface of the pressurized synthesis vessel 1 through a bracket. Gears 209 are fixedly installed on both the output end of the No. 1 motor 208 and the outer surface of the hollow rod 201, and the two gears 209 are movably meshed and connected. A slide 207 is fixedly installed on the lower surface inside the pressurized synthesis vessel 1 outside the reciprocating screw 204. The slide 207 passes through a plurality of material bowls 206 and is slidably connected to the material bowls 206.

[0027] In this embodiment, motor 208 operates, and through gear 209, the hollow rod 201 rotates, causing the stirring blades 203 to rotate, thus rotating the solution inside the pressurized synthesis vessel 1. Simultaneously, the reciprocating screw 204 rotates, and under the limiting action of the slide 207, multiple hoppers 206 move up and down synchronously with the sliding sleeve 205. When moving upward, the hoppers 206 scoop up the solution, causing the remaining solution to gather below the hoppers 206 in the pressurized synthesis vessel 1, pushing the bottom of the pressurized synthesis vessel 1. As the solid raw material moves downward, the bowl 206 pushes the solution downward, which in turn pushes the solid raw material to move. This causes the hollow rod 201 to rotate, moving the bowl 206 up and down. This allows the solution to flow at the bottom of the pressurized synthesis vessel 1, pushing the solid raw material that has accumulated at the center of the bottom of the pressurized synthesis vessel 1 to move outward. This prevents the solid raw material from depositing at the bottom of the pressurized synthesis vessel 1 and clogging the bottom valve. At the same time, it facilitates the uniform dispersion of the solid raw material throughout the pressurized synthesis vessel 1, thus accelerating the reaction rate.

[0028] like Figure 3-4 As shown, in this embodiment, the upper end of the hollow rod 201 passes through the hopper 301 and is rotatably connected to the hopper 301. A second motor 306 is fixedly installed on the upper surface of the hopper 301, and the output end of the second motor 306 is fixedly connected to the screw feed rod 305. A feed pipe 307 is fixedly embedded in the upper surface of the hopper 301, and an air inlet pipe 308 is fixedly embedded in the upper surface of the hopper 301. An air pipe 309 is provided inside the hollow rod 201, and the upper end of the air pipe 309 is fixedly connected to the air inlet pipe 308.

[0029] In practice, solid raw materials are fed into the reactor through the feed pipe 307, and nitrogen is pumped into the gas pipe 309 through the gas inlet pipe 308, allowing the nitrogen to enter the hollow rod 201. Then, the nitrogen is evenly discharged into the solution inside the pressurized synthesis reactor 1 through multiple through holes 202. The second motor 306 operates, driving the spiral feed rod 305 to rotate, assisting the solid raw materials to be fed into the hollow rod 201, giving the solid raw materials a moving force to facilitate their discharge from the through holes 202, so that the solid raw materials are evenly transported into the solution inside the pressurized synthesis reactor 1, thereby accelerating the reaction rate.

[0030] Example 2

[0031] Based on Example 1, in order to overcome the problem that solid raw materials tend to adhere to the inner wall of silo 301 in Example 1.

[0032] like Figure 3 As shown, in this embodiment, a second annular pipe 303 is fixedly installed on the upper surface inside the hopper 301. The first annular pipe 302 and the second annular pipe 303 are fixedly connected by a pipe. Multiple nozzles 304 are fixedly installed at equal intervals on the outer surfaces of the first annular pipe 302 and the second annular pipe 303. One end of the first annular pipe 302 is fixedly inserted through the upper surface of the hopper 301.

[0033] In practice, the liquid raw material is transported into the first annular pipe 302 and the second annular pipe 303, and discharged from multiple nozzles 304. The sprayed liquid raw material washes the inner wall of the hopper 301 and the spiral feeding rod 305, washing away the solid raw material adhering to their surfaces. This makes it easier to clean the inner wall of the solid raw material feeding pipe through the liquid raw material, reducing the difficulty of cleaning. At the same time, the liquid raw material reacts with the solid raw material during feeding, preventing the solid raw material from clogging the hollow rod 201 and speeding up the feeding speed.
