Description

Technical Field

[0001] The invention relates to the technical field of reactors, and in particular to a reactor for producing glyphosate isopropylamine salt water agent. Background Art

[0002] Glyphosate and isopropylamine undergo a chemical reaction in a reactor to generate glyphosate isopropylamine salt. The reaction conditions such as temperature, pressure, stirring speed, etc. can be precisely controlled in the reactor, so the reactor plays an important role to ensure the smooth progress of the reaction and the quality of the product. The heating or cooling device of the reactor can adjust the temperature in the reactor according to the needs of the reaction. In the early stage of the reaction, heating may be required to start the reaction. During the reaction, the temperature needs to be controlled to avoid side reactions. After the reaction is over, cooling may be required to terminate the reaction or facilitate subsequent processing. If the pH value changes too much during the chemical reaction, the temperature may be too high and may exceed 80 degrees Celsius. The optimal reaction temperature of glyphosate and isopropylamine is 70 to 80 degrees Celsius, so the cooling system plays an important role. At present, most cooling equipment uses cooling water and cooling kerosene. When the temperature rises too high due to the optimal reaction temperature required by glyphosate and isopropylamine or the unstable pH value, the cooling water may produce water bubbles, forming a bubble heat-insulating layer to prevent the heat inside the engine from dissipating, and also causing water rust and scale, aggravating the aging of the cooling system and reducing the heat dissipation performance. The cooling equipment adopts cooling kerosene for cooling, wherein the cooling kerosene achieves the heat dissipation effect by absorbing heat. The existing cooling equipment is installed on the outer wall of the reactor. When the heat dissipation time needs to be shortened, the cooling kerosene needs to have a flow rate. Therefore, it is necessary to provide the cooling equipment with a flow rate for the cooling kerosene. The maintenance cost and operation process are relatively complicated.

[0019] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described in combination with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Example: Refer to Figures 1 to 3The present invention provides a technical solution: a reaction kettle for producing glyphosate isopropylamine salt water agent, comprising: a stirring tank 1, a support frame is provided at the top of the stirring tank 1, a stirring and cooling mechanism is provided on the inner wall of the stirring tank 1, a liquid storage tank 14 is provided on the outer wall of the support frame, a motor 11 is fixedly installed on the top of the support frame, a driving rod 10 is fixedly installed on the output shaft of the motor 11, an optical axis 101 is fixedly installed on the inner fixed part of the driving rod 10, and the outer wall of the optical axis 101 penetrates and is rotatably connected to the top of the stirring tank 1; It is characterized in that the stirring and cooling mechanism also includes a liquid inlet pipe 15 and a liquid outlet pipe 18 which penetrate through and are fixedly connected to the bottom end of the driving rod 102, and the bottom ends of the liquid inlet pipe 15 and the liquid outlet pipe 18 are respectively rotatably connected to the stirring member 1 2 and the stirring member 2 3. When cooling is performed, the cooling kerosene in the liquid storage tank 14 flows from the liquid inlet pipe 15 to the stirring member 1 2 and the stirring member 2 3, and finally flows back to the liquid storage tank 14 from the liquid outlet pipe 18. In addition, during the rotating stirring process of the stirring member 1 2 and the stirring member 2 3, the reactants can be contacted and cooled.

[0022] like Figure 1 and Figure 2 As shown, a mounting seat 12 is fixedly installed on the outer wall of the motor 11 near the top, a mounting rod 13 is fixedly installed on one side of the mounting seat 12, and the other side of the mounting rod 13 is fixedly installed on the top of a liquid storage tank 14. The outer wall of the liquid storage tank 14 near the top is connected to one end of a liquid outlet pipe 18, and the outer wall of the liquid storage tank 14 near the bottom is connected to one end of a liquid inlet pipe 15.

[0023] When the temperature of the reactants in the stirring tank 1 exceeds eighty degrees Celsius, the cooling kerosene in the liquid storage tank 14 will flow from the liquid inlet pipe 15 into the stirring members 1 2 and 2 3, and at the same time, the driving rod 2 102 and the optical axis 101 are driven by the motor 11 to keep rotating and stirring, that is, the stirring members 1 2 and 2 3 achieve the effect of timely cooling by having more contact with the reactants during the rotation process, and at the same time, the cooling kerosene is allowed to have a flow rate through the stirring and cooling mechanism. After the cooling kerosene in the stirring members 2 3 enters the liquid storage tank 14, it finally flows from the liquid inlet pipe 15 into the stirring members 1 2 and 2 3 and circulates repeatedly until the temperature is lower than eighty degrees Celsius. Compared with cooling through the peripheral surface of the stirring tank 1, the present invention can directly cool the reactants in time, while when cooling through the peripheral surface of the stirring tank 1, the temperature of the stirring tank 1 needs to be cooled down before the reactants can be cooled, which will increase the cooling time.

[0024] like Figure 2 , Figure 5 , Fig. 9 and Fig.10As shown, a circular plate 55 and a circular ring 54 are fixedly installed on the inner wall of the liquid inlet pipe 15 away from the driving rod 10, a piston 15 and a piston 2 51 are sealed and slidably provided on the inner wall of the liquid inlet pipe 15, a connecting rod 50 is fixedly installed on the opposite side of the piston 15 and the piston 2 51, the piston 15 and the piston 2 51 are respectively located on the left and right sides of the circular ring 54, hydrogen is filled between the piston 2 51 and the circular plate 55, a liquid inlet groove 2 53 is opened on the inner wall of the liquid inlet pipe 15, the liquid inlet groove 2 53 is composed of a left vertical groove, a right vertical groove and a transverse groove, the left vertical groove and the right vertical groove are respectively connected to the two sides of the transverse groove, the right vertical groove is located between the circular plate 55 and the driving rod 10, and the left vertical groove is located between the circular plate 55 and the driving rod 10. 4 and the piston 2 51, a liquid inlet groove 1 52 is opened at the center of the piston 5, and a connecting rod 50 is connected to the opposite side of the liquid inlet groove 1 52 and the piston 2 51, the connecting rod 50 is an L-shaped groove, and the liquid inlet groove 1 52 and the piston 2 51 both have open ends, and the open end of the piston 2 51 can be connected to the left vertical groove, the inner walls of the driving rod 10 and the driving rod 2 102 are both provided with an annular groove 103, and the inner wall of the annular groove 103 is sealed and rotated with a fixed ring 16, the outer walls of the liquid inlet pipe 15 and the liquid outlet pipe 18 are both penetrated and fixedly connected to one side of the fixed ring 16, the outer wall of the fixed ring 16 is fixedly installed with a support rod 17, and the other side of the support rod 17 is fixedly installed on the top of the stirring tank 1.

[0025] Before filling hydrogen between the circular plate 55 and the second piston 51, ensure that the ambient temperature is around zero degrees Celsius, and then fill it with hydrogen. Calculated by hydrogen pressure, volume, amount of substance, ideal gas constant and thermodynamic temperature equation, the volume of hydrogen increases by about 30%, that is, when the temperature exceeds the limit of 80 degrees Celsius, the volume of hydrogen increases, and the second piston 51 and the first piston 5 move away from the circular plate 55 until the second piston 51 contacts one side of the ring 54 or the open end of the second piston 51 is connected to the liquid inlet tank 2 53, and the cooling kerosene flows from the open end of the first piston 5 into the stirring member 1 2 and the second stirring member 2 3. When the temperature drops to 70 to 80 degrees Celsius, the hydrogen will reduce in volume, and the first piston 5 and the second piston 51 move toward the circular plate 55. The open end of the second piston 51 is no longer connected to the liquid inlet tank 2 53, thereby avoiding heat dissipation in the stirring tank 1 during heating.

[0026] like Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, the stirring member 2 is composed of an upper lateral end for liquid inlet, a lower lateral end for liquid inlet and a vertical end for liquid inlet. The upper lateral end for liquid inlet and the lower lateral end for liquid inlet are respectively connected to the upper and lower ends of the vertical end for liquid inlet. The inner wall of the vertical end for liquid inlet is provided with an annular groove 22 and a plurality of liquid-passing grooves 43 arranged in a circumferential array. An acceleration ring 4 is provided on the inner wall of the annular groove 22 for sealing and rotating. The inner ring of the acceleration ring 4 is a concave ring. A plurality of acceleration sheets 41 are arranged in a circumferential array on the inner ring of the acceleration ring 4. A plurality of acceleration plates 40 are arranged in a circumferential array on the outer wall of the acceleration ring 4. The height of the concave ring is equal to the height of the liquid-passing groove 43. A one-way valve 20 is passed through and fixedly connected to one end of the lower lateral end for liquid inlet. The outer wall of the lower lateral end for liquid inlet is connected with a hydraulic pipe 2. 1. The hydraulic pipe 21 is an L-shaped pipe. The hydraulic pipe 21 consists of a hydraulic transverse end and a hydraulic vertical end. Two limiting rings 23 are fixedly installed on the inner wall of the hydraulic vertical end. A hydraulic plug 1 22 is sealed and slidably provided on the inner wall of the hydraulic vertical end. The hydraulic plug 1 22 is located between the two limiting rings 23. A hydraulic plug 24 is sealed and slidably provided on the inner wall of the hydraulic transverse end. A spring 1 25 is fixedly installed on one side of the hydraulic plug 24. The other end of the spring 1 25 is fixedly installed on the inner wall of the hydraulic transverse end. A pull rod 1 26 is fixedly installed on one side of the hydraulic plug 24. One end of the pull rod 1 26 is slidably inserted into one end of the hydraulic transverse end. A hemispherical body 27 is fixedly installed on the end of the pull rod 1 26 away from the hydraulic transverse end. A pull rod 28 is fixedly installed on the inner wall of the mixing tank 1, and a driving sphere 29 is fixedly installed on the end of the pull rod 28 away from the inner wall of the mixing tank 1. The driving sphere 29 can contact the hemisphere 27, and the pull rod 28, the driving sphere 29, the pull rod 1 26 and the hemisphere 27 are in the same plane.

[0027] During the rotation of the stirring member 2, the outer wall of the acceleration ring 4 rotates in the reactant through multiple acceleration plates 40, and the multiple acceleration plates 40 are in the reactant. During the rotation of the acceleration ring 4, the multiple acceleration plates 41 of the inner ring drive the cooling kerosene to rotate, thereby increasing the rotation speed of the cooling kerosene, allowing the cooling kerosene close to the inner wall of the stirring member 2 and the cooling kerosene far from the inner wall of the stirring member 2 to increase the heat transfer speed, thereby overcoming the slow heat transfer speed of the cooling kerosene. During the rotation of the stirring member 2, the one-way valve 20 is used to prevent the cooling kerosene from flowing back, and the one-way valve 20 adopts the existing The one-way control valve and the hydraulic pipe 21 will also rotate with the stirring member 2. Every time it rotates one circle, the hemisphere 27 will contact the driving ball 29, that is, the pull rod 26 will move toward the direction of the hydraulic pipe 21, and the hydraulic plug 24 will squeeze the hydraulic plug 22 up and down between the two limit rings 23 through air pressure. When the hydraulic plug 22 moves downward, the one-way valve 20 opens its inner wall to allow the cooling kerosene to enter the hydraulic pipe 21, and then when the hydraulic plug 22 moves upward, the one-way valve 20 will close its inner wall, and the cooling kerosene will move toward the inner wall of the stirring member 23, as shown in the attached figure. Figure 3The flow direction of the cooling kerosene is shown, which makes it possible to draw away the cooling kerosene through the structure of the inner wall of the stirring member 2 3 when cooling is not needed later, so as to avoid affecting the subsequent heating process.

[0028] like Figures 3 to 7 As shown, the stirring member 2 3 is composed of an upper lateral end for liquid discharge, a lower lateral end for liquid discharge and a vertical end for liquid discharge, the upper lateral end for liquid discharge and the lower lateral end for liquid discharge are respectively connected to the upper and lower ends of the vertical end for liquid discharge, a liquid discharge ring 30 is provided on the inner wall of the lower lateral end for liquid discharge, a spring 2 31 is fixedly installed on one side of the liquid discharge ring 30, a liquid discharge plug 32 is fixedly installed on the other end of the spring 2 31, an L-shaped liquid discharge groove 33 is provided on the inner wall of the liquid discharge plug 32, a liquid discharge groove 34 is provided on the inner wall of the lower lateral end for liquid discharge and the L-shaped liquid discharge groove 33 and the liquid discharge groove 34 are connected to each other when they are in the same plane, and the inner wall seal of the stirring member 2 3 is rotated There is a storage shell 36, and a connecting pipe 35 is connected between the upper lateral end of the liquid outlet and the lower lateral end of the liquid outlet. The outer wall of the connecting pipe 35 close to the upper lateral end of the liquid outlet is fixedly installed with the storage shell 36, and the inner wall of the connecting pipe 35 is rotatably connected with a circular baffle 37, the top of the circular baffle 37 is inclined, and the circular baffle 37 can be embedded in the inner wall of the storage shell 36, and the inner wall of the connecting pipe 35 is rotatably connected with a rotating rod 38, and a fan blade 39 is fixedly installed at one end of the rotating rod 38 close to the connecting pipe 35, and a liquid-removing blade 301 is fixedly installed at one end of the rotating rod 38 away from the inner wall of the connecting pipe 35.

[0029] When the hydraulic plug 1 22 moves downward, the liquid outlet plug 32 moves toward the liquid outlet ring 30 through the pumping of air pressure, and at the same time squeezes the spring 2 31, so that the L-shaped liquid outlet groove 33 and the liquid outlet groove 34 cannot be connected. When the hydraulic plug 1 22 moves upward, the liquid outlet plug 32 moves away from the liquid outlet ring 30, and the spring 2 31 can provide the liquid outlet plug 32 with acceleration, so that the L-shaped liquid outlet groove 33 and the liquid outlet groove 34 are connected, that is, the cooling kerosene is discharged from the liquid outlet ring 30. , the L-shaped liquid outlet groove 33 and the liquid outlet groove 34 flow into the inner wall of the stirring member 2 3. When the cooling kerosene in the stirring member 2 3 and the stirring member 1 2 needs to be pumped into the liquid storage tank 14, the liquid outlet plug 32 and the L-shaped liquid outlet groove 33 have limited space to avoid that when there is no cooling kerosene in the stirring member 1 2, there is only gas in the L-shaped liquid outlet groove 33 and the liquid outlet groove 34. When the liquid outlet plug 32 moves toward the liquid outlet ring 30, the cooling kerosene may flow back into the hydraulic pipe 21; When the liquid or air pressure drives the receiving shell 36 to move to the connecting pipe 35 and the lower horizontal end of the liquid outlet, in order to prevent the liquid outlet plug 32 from moving forward and backward and using air pressure to push the cooling kerosene to generate gas that will enter the cooling kerosene and form bubbles, thereby causing the cooling kerosene to flow at a reduced speed or unable to flow, the receiving shell 36 is pushed by air pressure, and then the receiving shell 36 pushes the cooling kerosene to move into the liquid outlet pipe 18, and finally flows into the liquid storage tank 14; During the process of the storage shell 36 pushing the cooling kerosene, it may happen that when the storage shell 36 is on the inner wall of the lower lateral end of the liquid outlet, the right lower lateral end of the liquid outlet is being pushed by the storage shell 36, but there will be a little cooling kerosene on the left side of the storage shell 36. Figure 3 As shown, when the storage shell 36 reaches above the circular baffle 37, the circular baffle 37 will flip downward due to air pressure and the self-gravity of the storage shell 36, allowing the storage shell 36 to enter the inner wall of the connecting pipe 35. At the same time, during the rotation of the stirring member 23, the liquid-displacing blades 301 rotate in the reactants, and a self-rotation phenomenon will occur, that is, the rotating rod 38 rotates to drive the fan blades 39 to rotate and generate wind force, which blows up a small amount of cooling kerosene originally remaining in the storage shell 36, preventing a small amount of cooling kerosene from entering the inner wall of the connecting pipe 35, and finally that small amount of cooling kerosene also enters the liquid outlet pipe 18. When the cooling kerosene enters the inner wall of the stirring member 23, it can enter the inner wall of the connecting pipe 35 from the bottom end. However, because the circular baffle 37 cannot automatically flip upward, the cooling kerosene cannot enter the inner wall of the upper horizontal end of the liquid outlet from the inner wall of the connecting pipe 35.

[0030] Working principle: When the temperature of the reactants in the stirring tank 1 exceeds 80 degrees Celsius, and the driving rod 102 and the optical axis 101 are driven by the motor 11 to keep rotating and stirring, that is, when the temperature exceeds the limit of 80 degrees Celsius, the volume of hydrogen increases, and the piston 51 and the piston 15 move away from the circular plate 55 until the piston 51 contacts one side of the ring 54 or the open end of the piston 51 is connected to the liquid inlet tank 2 53, and its cooling kerosene flows from the open end of the piston 15 into the stirring member 1 2 and the stirring member 2 3. When the temperature drops to 70 to 80 degrees Celsius, the hydrogen will reduce in volume, and the piston 15 and the piston 2 51 move toward the circular plate 55, and the open end of the piston 51 is no longer connected to the liquid inlet tank 2 53, thereby avoiding heat dissipation in the stirring tank 1 during heating. The volume change of hydrogen can control the cooling kerosene to flow from the liquid inlet pipe 15 into the stirring member 1 2 and the stirring member 2 3. When the hydraulic plug 1 22 moves downward, the one-way valve 20 opens the inner wall to allow the cooling kerosene to enter the hydraulic pipe 21. Then, when the hydraulic plug 1 22 moves upward, the one-way valve 20 closes its inner wall, and the cooling kerosene moves toward the inner wall of the stirring member 2 3. Figure 3 The flow direction of the cooling kerosene is shown, which is convenient for the cooling kerosene to be drawn away through the structure of the inner wall of the stirring member 2 3 when cooling is not required later, so as to avoid affecting the subsequent heating process; When the hydraulic plug 1 22 moves downward, the liquid outlet plug 32 moves toward the liquid outlet ring 30 through the pumping of air pressure, and at the same time squeezes the spring 2 31, so that the L-shaped liquid outlet groove 33 and the liquid outlet groove 34 cannot be connected. When the hydraulic plug 1 22 moves upward, the liquid outlet plug 32 moves away from the liquid outlet ring 30, and the spring 2 31 can provide the liquid outlet plug 32 with acceleration, so that the L-shaped liquid outlet groove 33 and the liquid outlet groove 34 are connected, that is, the cooling kerosene is discharged from the liquid outlet ring 30. , the L-shaped liquid outlet groove 33 and the liquid outlet groove 34 flow into the inner wall of the stirring member 2 3. When the cooling kerosene in the stirring member 2 3 and the stirring member 1 2 needs to be pumped into the liquid storage tank 14, the liquid outlet plug 32 and the L-shaped liquid outlet groove 33 have limited space to avoid that when the stirring member 2 has no cooling kerosene, there is only gas in the L-shaped liquid outlet groove 33 and the liquid outlet groove 34. When the liquid outlet plug 32 moves toward the liquid outlet ring 30, the cooling kerosene may flow back into the hydraulic pipe 21.
