Description

Technical Field

[0001] This invention belongs to the technical field of reaction devices, specifically a continuous condensation reaction device for glyphosate processing. Background Technology

[0002] In the processing and production of glyphosate, the condensation reaction unit is one of the core pieces of equipment. Its core function is to promote the condensation reaction between raw material molecules by controlling reaction conditions such as temperature, pH, and material ratio, thereby removing small molecules such as water and methanol to generate larger molecular intermediates or target products.

[0003] The production process of glyphosate is mainly based on the iminodiacetic acid (IDA) method. Its core condensation reaction is divided into two steps: iminodiacetic acid (IDA) and formaldehyde (HCHO) undergo a condensation reaction under certain conditions to generate hydroxymethylation intermediates (such as N-(hydroxymethyl)iminodiacetic acid or similar derivatives).

[0004] The second condensation step: the above hydroxymethylated intermediate is further condensed with glycine (NH2CH2COOH) or its salt to finally generate glyphosate (N-(phosphonomethyl)glycine);

[0005] However, existing continuous condensation reaction devices have certain shortcomings in use. The continuous reactor is a tubular structure. By controlling the flow rate, such as the volumetric flow rate and reactor volume of the tubular reactor, the residence time can be accurately calculated to enable continuous production of the target product. Its tube structure is fixed with flanges. After long-term use, solids will form on the surface of the heating rod inside the tube, thereby reducing the gap between the tube and the heating rod, making the liquid flow obstructed and affecting its continuous output effect.

[0006] In summary, the existing continuous condensation reaction apparatus cannot be cleaned internally, leading to blockages in the internal pipe walls after prolonged use. This reduces the liquid flow rate and affects the output efficiency of the continuous condensation reaction apparatus. Utility Model Content

[0007] This utility model provides a continuous condensation reaction apparatus for glyphosate processing, which can solve the technical problem in the prior art where the internal structure of the continuous condensation reaction apparatus cannot be cleaned, causing blockage of the internal pipe walls after prolonged use, reducing the liquid flow rate, and affecting the output efficiency of the continuous condensation reaction apparatus:

[0008] A continuous condensation reaction apparatus for glyphosate processing includes an outer shell, a main feed pipe, and several sets of auxiliary feed pipes. The main feed pipe is fixedly installed on the front outer surface of the outer shell, and the several sets of auxiliary feed pipes are fixedly installed on the upper outer surface of the outer shell. The main feed pipe and the several sets of auxiliary feed pipes are connected through several sets of conveying pipes. The several sets of conveying pipes are connected and fixed by a mixer. Several sets of outer sleeves are provided at the lower end of the conveying pipes. The several sets of outer sleeves are connected through each other in an S-shape. Heating rods are movably installed inside each of the several sets of outer sleeves. One end of each set of heating rods is connected and fixed by a connecting plate.

[0009] As a further technical solution of this utility model, a sealing plug is fixedly installed on the outer surface of one end of the heating rod, and a sealing sleeve for use with the sealing plug is fixedly installed on the inner side of one end of several sets of outer tubes. The outer tube and the heating rod adopt a pull-out structure design. When crystals are generated on the surface of the heating rod, several sets of heating rods can be pulled out at the same time using the connecting plate, which facilitates the cleaning operation of the surface of the heating rod. The setting of the sealing plug and the sealing sleeve ensures the airtightness between the outer tube and the heating rod.

[0010] As a further technical solution of this utility model, a docking sleeve is fixedly installed on the outer side surface of the connecting plate, and a fixing rod for use with the docking sleeve is fixedly installed on the outer surface of one end of the outer shell. By using the fixing rod to dock with the docking sleeve, it can be inserted between the outer tube and the heating rod to fix the connecting plate.

[0011] As a further technical solution of this utility model, several sets of outer tubes are connected in series through the tube body, and the outer tubes and the conveying tubes are connected in a through connection. The condensation of hydroxymethyl intermediate and glycine is carried out by mixing raw materials such as hydroxymethylation intermediate, glycine, phosphonic acid and liquid alkali using a mixer. The outer tube with S-shaped structure can effectively extend the reaction time of the raw materials. With the setting of heating rod, when the raw materials are conveyed in the outer tube, their temperature is controlled at 60-80℃, which accelerates the nucleophilic reaction.

[0012] As a further technical solution of this utility model, a conical head is fixedly installed on the outer surface of one end of the sealing plug, and a conical collar for use with the conical head is fixedly installed on the inner side of the sealing sleeve. When the sealing plug and the sealing sleeve are connected, the conical head and the conical collar are connected to each other, thereby improving the sealing performance after the outer sleeve and the heating rod are connected.

[0013] As a further technical solution of this utility model, the inner side of the conical collar is provided with an arc-shaped groove, and the outer surface of the conical head is provided with a sealing ring that matches the arc-shaped groove. The arc-shaped groove and the sealing ring are connected to each other, which can increase the sealing effect between the conical collar and the conical head.

[0014] As a further technical solution of this utility model, the mixer includes a docking sleeve, and the inner surfaces of both ends of the docking sleeve are threaded. The mixer can play a turbulent mixing role on the raw materials, so that the raw materials are fully mixed.

[0015] As a further technical solution of this utility model, a first disc is fixedly installed on the outer surface of one end of the docking sleeve, and a second disc is fixedly installed on the outer surface of the other end of the docking sleeve.

[0016] As a further technical solution of this utility model, several sets of strip-shaped slots are provided through the outer surfaces of the first and second disks. The strip-shaped slots of the first and second disks are staggered in a cross shape. A mixing chamber is provided inside the connecting sleeve between the first and second disks. Compared with the traditional mesh structure, the strip-shaped slots are larger, which makes the liquid flow faster through the strip-shaped slots. The two sets of cross-shaped staggered strip-shaped slots play a dual mixing role for passing through the first and second disks. Because there is a certain distance between the first and second disks, this part of the connecting sleeve space is a mixing chamber, so that after the liquid passes through the first disk, it travels a certain distance before passing through the second disk, reducing the resistance during liquid mixing.

[0017] As a further technical solution of this utility model, a discharge pipe is installed on one side of the outer shell, and a lifting push rod is installed at the front end of the outer shell. The discharge pipe can be used to discharge the liquid after the condensation reaction, and the lifting push rod can separate the two-section outer shell.

[0018] The beneficial effects of this utility model are as follows: By using a sealing plug and a connecting plate, this utility model provides a pull-out auxiliary structure to the internal tube of the continuous condensation reaction device for glyphosate processing, making the internal cleaning of the coil more convenient and ensuring stable output. The pull-out structure design between the outer tube and the heating rod allows several sets of heating rods to be pulled out simultaneously when crystals form on the surface of the heating rod, facilitating cleaning of the heating rod surface. The sealing plug and sealing sleeve ensure the airtightness between the outer tube and the heating rod. The connecting plate is fixed by inserting a fixed rod into the connecting sleeve between the outer tube and the heating rod. Pulling out the fixed rod and pulling the connecting plate outwards allows several sets of heating rods to be pulled out simultaneously, enabling cleaning of the coil-like outer tube. When the sealing plug and sealing sleeve are connected, the conical head and conical collar connect with each other, improving the sealing performance of the outer tube and heating rod after connection.

[0019] By incorporating a mixer into the continuous condensation reaction apparatus for glyphosate processing, an auxiliary mixing structure is provided. This enhances the mixing effect while ensuring the raw material conveying speed. The user adds ingredients into the conveying pipe through the auxiliary pipe. Compared to the traditional mesh structure, the strip grooves are larger, allowing the liquid to flow through them at a faster speed. The two sets of cross-shaped staggered strip grooves provide a dual mixing effect for the liquid passing through the first and second discs, further improving the mixing effect. Because there is a certain distance between the first and second discs, this space between the mating sleeves forms a mixing chamber. This allows the liquid to travel a certain distance after passing through the first disc before passing through the second disc, reducing resistance during liquid mixing and ensuring the mixing effect.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0027] like Figures 1-4As shown, the continuous condensation reaction device for glyphosate processing includes an outer shell 1, a main feed pipe 2, and several sets of auxiliary feed pipes 4. The main feed pipe 2 is fixedly installed on the front outer surface of the outer shell 1, and the several sets of auxiliary feed pipes 4 are fixedly installed on the upper outer surface of the outer shell 1. The main feed pipe 2 and the several sets of auxiliary feed pipes 4 are connected through several sets of conveying pipes 13. The several sets of conveying pipes 13 are connected and fixed through a mixer 14. Several sets of outer sleeves 7 are provided at the lower end of the conveying pipes 13. The several sets of outer sleeves 7 are connected through each other in an S-shape. Heating rods 8 are movably installed inside each of the several sets of outer sleeves 7. One end of each set of heating rods 8 is connected and fixed through a connecting plate 11.

[0028] A sealing plug 10 is fixedly installed on the outer surface of one end of the heating rod 8. A sealing sleeve 9 for use with the sealing plug 10 is fixedly installed on the inner side of one end of several sets of outer tubes 7. The outer tube 7 and the heating rod 8 adopt a pull-out structure design. When crystals are generated on the surface of the heating rod 8, several sets of heating rods 8 can be pulled out at the same time using the connecting plate 11, which facilitates the cleaning operation of the surface of the heating rod 8. The setting of the sealing plug 10 and the sealing sleeve 9 ensures the airtightness between the outer tube 7 and the heating rod 8.

[0029] A docking sleeve 12 is fixedly installed on the outer side surface of the connecting plate 11, and a fixing rod 6 for use with the docking sleeve 12 is fixedly installed on the outer surface of one end of the outer shell 1. The fixing rod 6 is used to dock the docking sleeve 12, and can be inserted between the outer tube 7 and the heating rod 8 to fix the connecting plate 11.

[0030] Several sets of outer tubes 7 are connected in series through the tube body. The outer tubes 7 and the feed pipe 13 are connected in a continuous manner. The condensation of hydroxymethyl intermediate and glycine is carried out by mixing raw materials such as hydroxymethylation intermediate, glycine, phosphonic acid and liquid alkali using a mixer 14. The outer tubes 7 with S-shaped structure can effectively extend the reaction time of the raw materials. With the setting of heating rod 8, when the raw materials are transported in the outer tubes 7, their temperature is controlled at 60-80℃ to accelerate the nucleophilic reaction.

[0031] A conical head 19 is fixedly installed on the outer surface of one end of the sealing plug 10, and a conical collar that works with the conical head 19 is fixedly installed on the inner side of the sealing sleeve 9. When the sealing plug 10 and the sealing sleeve 9 are connected, the conical head 19 and the conical collar are connected to each other, which improves the sealing performance of the outer sleeve 7 and the heating rod 8 after they are connected.

[0032] The inner side of the conical collar is provided with an arc-shaped groove 20, and the outer surface of the conical head 19 is provided with a sealing ring that matches the arc-shaped groove 20. The arc-shaped groove 20 and the sealing ring are connected to each other, which can increase the sealing effect between the conical collar and the conical head 19.

[0033] The mixer 14 includes a docking sleeve 16, the inner surfaces of both ends of the docking sleeve 16 are threaded. The mixer 14 can play a turbulent mixing role for the raw materials, so that the raw materials are fully mixed.

[0034] A first disc 15 is fixedly installed on the outer surface of one end of the mating sleeve 16, and a second disc 17 is fixedly installed on the outer surface of the other end of the mating sleeve 16.

[0035] The outer surfaces of the first disk 15 and the second disk 17 are both perforated with several sets of strip-shaped slots 18. The strip-shaped slots 18 of the first disk 15 and the second disk 17 are staggered in a cross shape. The interior of the connecting sleeve 16 is provided with a mixing chamber between the first disk 15 and the second disk 17. Compared with the traditional mesh structure, the slots 18 are larger, which makes the liquid flow faster through the slots 18. The two sets of cross-shaped staggered strip-shaped slots 18 play a dual mixing role in passing through the first disk 15 and the second disk 17. Because there is a certain distance between the first disk 15 and the second disk 17, this part of the space of the connecting sleeve 16 is a mixing chamber, so that after the liquid passes through the first disk 15, it travels a certain distance before passing through the second disk 17, reducing the resistance during liquid mixing.

[0036] A discharge pipe 5 is installed on one side of the outer shell 1, and a lifting push rod 3 is installed at the front end of the outer shell 1. The discharge pipe 5 can be used to discharge the liquid after the condensation reaction. The lifting push rod 3 can separate the two-section outer shell 1.

[0037] The continuous condensation reaction apparatus for glyphosate processing, during operation, features a pull-out auxiliary structure in its internal tubes via a sealing plug 10 and a connecting plate 11. This facilitates easier cleaning of the coils and ensures stable output. The outer tube 7 and heating rods 8 are connected by a pull-out structure. When crystals form on the surface of the heating rods 8, several sets of heating rods 8 can be simultaneously pulled out using the connecting plate 11 for convenient cleaning. The sealing plug 10 and the connecting plate 11 further enhance the efficiency of the continuous condensation reaction apparatus. The setting of the sleeve 9 ensures the airtightness between the outer tube 7 and the heating rod 8. The fixing rod 6 is connected to the connecting sleeve 12. After being inserted between the outer tube 7 and the heating rod 8, it can fix the connecting plate 11. By pulling out the fixing rod 6 and pulling the connecting plate 11 outward, several sets of heating rods 8 can be pulled out at the same time, so that the coil-shaped outer tube 7 can be cleaned. When the sealing plug 10 and the sealing sleeve 9 are connected, the conical head 19 and the conical collar are connected to each other, which improves the sealing performance after the outer tube 7 and the heating rod 8 are connected.

[0038] By setting up a mixer 14, the continuous condensation reaction device for glyphosate processing is equipped with an auxiliary mixing structure, which improves the mixing effect while ensuring the raw material conveying speed. The user adds ingredients into the conveying pipe 13 through the auxiliary material pipe 4. Compared with the traditional mesh structure, the slot 18 has a larger slot, which makes the liquid flow faster through the slot 18. The two sets of cross-shaped staggered slots 18 play a dual mixing role for passing through the first disc 15 and the second disc 17. Because there is a certain distance between the first disc 15 and the second disc 17, the space of the connecting sleeve 16 in this part is a mixing chamber, so that after the liquid passes through the first disc 15, it travels a certain distance before passing through the second disc 17, which reduces the resistance during liquid mixing and ensures the mixing effect of the liquid.

[0039] The above description is merely an example and illustration of the structure of this utility model.
