Description

Technical Field

[0001] The invention relates to the technical field of chemical reaction equipment, and in particular to a reaction device for synthesizing high molecular weight N-halamine resin. Background Art

[0002] Synthetic polymer N-halamine resin is a material having an N-halamine structure formed by introducing halogen atoms into a polymer containing an amino group through a chemical reaction. N-halamine resin is a special polymer material. These resins have unique properties, such as chemical resistance, antimicrobial resistance and flame retardancy, and are therefore used in many industries. The chemical reaction for the synthetic polymer N-halamine resin usually needs to be carried out in a chemical reaction equipment. For example, a chemical reaction equipment disclosed in application number CN201610513558.9 carries out a chemical reaction in a chemical reaction equipment.

[0003] In the process of synthesizing polymer N-halamine resin, polymer materials usually have a higher molecular weight, resulting in stronger entanglement and interaction between molecular chains, showing higher viscosity, and temperature has a significant effect on material viscosity: as the temperature rises, the activity of the molecular chain increases, the interaction between molecules weakens, and the viscosity decreases; conversely, when the temperature decreases, the viscosity increases, but the existing reaction equipment usually performs synthesis at a constant temperature, so as the stirring and reaction proceed, the material may become too viscous or too thin. Synthetic polymer N-halamine resin that is too viscous may increase the difficulty of processing, be difficult to stir, and cause uneven mixing; while synthetic polymer N-halamine resin that is too thin may reduce the concentration of reactants, thereby affecting the reaction rate. In order to ensure the normal progress of the reaction, the viscosity of the N-halamine resin needs to be controlled by adjusting the temperature within a suitable temperature range; The synthesis of high molecular weight N-halamine resins usually needs to be carried out under neutral to weakly alkaline pH conditions, and the specific pH range is usually between 7 and 9. Alkaline conditions can accelerate the decomposition of halogen compounds and generate more active halogen intermediates, thereby increasing the reaction rate. However, under acidic conditions, side reactions may occur, such as disproportionation reactions of halogen compounds or other undesirable chemical reactions, which will lead to reduced product purity or changes in properties. Existing reaction equipment cannot automatically control the pH value during the reaction according to the pH of the synthetic high molecular weight N-halamine resin. Since acidic substances or acidic by-products may be generated during the reaction, the pH value of the reaction system may gradually decrease, resulting in pH fluctuations, which in turn affects the stability of the reaction and the quality of the product.

[0013] Compared with the known prior art, the technical solution provided by the present invention has the following beneficial effects: The viscosity of the resin is fed back by detecting the moving distance of the detection plate. When the viscosity of the resin increases, the friction between the resin and the detection plate also increases, causing the detection plate to move to the side away from the connecting spring. This movement drives the second permanent magnet and the conductive sheet to slide on the resistance plate. The current monitor in the PLC controller can detect the current change of the sliding rheostat, thereby monitoring the viscosity of the resin in real time. When the PLC controller detects that the viscosity of the resin exceeds the preset range, the controller will open the current channel between the sliding rheostat and the electromagnetic block to increase the current passing into the electromagnetic block. As the current increases, the repulsive force of the electromagnetic block on the permanent magnet block will also increase, pushing the heating rod to move downward. When the heating rod moves downward, the sealing ring draws out the air in the heating chamber through the pressure control port, driving the conductive ring to move upward, thereby increasing the resistance length of the resistance rod, thereby increasing the heating power of the heating rod, and quickly transferring heat to the resin through the heat conduction plate to reduce the viscosity of the resin.

[0014] During the reaction process, if hydrogen halide gas is generated, the gas will enter the multi-stage telescopic shell through the vent when the extrusion plate moves downward. Subsequently, the water spray head sprays water to contact the gas, and the hydrogen halide gas reacts with water to generate hydrogen ions and halogen ions and release heat. This heat change is captured by the thermistor, and its resistance changes accordingly. The PLC controller determines the generation of hydrogen halide gas based on the resistance change of the thermistor, and controls the flow solenoid valve to open, and sprays an appropriate amount of alkaline solution into the reaction system through the liquid outlet pipe to adjust the pH value. When the pH value reaches the preset range, the PLC controller will close the flow solenoid valve and stop adding the alkaline solution to achieve the effect of adaptively controlling the pH value.

[0026] Among them, a liquid storage chamber 27 is opened inside the extrusion plate 21, and an alkaline solution is perfused in the liquid storage chamber 27. The inside of the liquid storage chamber 27 is fixedly connected with a liquid outlet pipe 28, and a flow solenoid valve 29 is arranged in the liquid outlet pipe 28.

[0028] The working principle of the present invention is as follows: First, the raw materials of the reaction are put into the reaction tube 3 through the discharge port, and then the removable sealing cover is re-sealed into the discharge port, and then the motor 17 is started, and the threaded rod 18 and the heating rod 16 are driven by the motor 17 to rotate synchronously, and the stirring frame 19 is driven by the threaded rod 18 to rotate, and the heat conducting plate 157 is driven by the heating rod 16 to stir and mix the raw materials. Stirring during the reaction process can increase the collision chance between the reactant molecules, thereby increasing the reaction rate. Evenly dispersed reactants are more likely to react chemically, which speeds up the reaction process. Then, the conductive ring 1510 is energized, and then the current is transmitted to the resistor 159. When the current passes through the conductor, the electrons collide with the atoms in the conductor. These collisions cause energy loss, which is converted into heat, thereby heating the raw materials.

[0029] Then, as the reaction proceeds, the molecular weight increases, and the molecular chains become entangled with each other, causing the viscosity of the system to gradually increase. Excessive viscosity will make stirring too difficult. In order to ensure the stirring of the raw materials, the stirring force needs to be increased, but this will cause a large shear force on the resin. Under the action of high shear force, the polymer chain may break, causing the molecular weight distribution of the resin to become wider, and may even reduce the average molecular weight. This will affect the physical and chemical properties of the resin, such as mechanical strength, heat resistance, and chemical corrosion resistance, so the viscosity of the resin needs to be controlled in real time.

[0030] By continuously stirring the resin, the viscosity of the resin will generate a greater friction force between the resin and the detection plate 11, and then the resin drives the detection plate 11 to move to the side away from the connecting spring 112. The greater the viscosity of the resin, the greater the friction force, so the moving distance of the detection plate 11 is farther. The smaller the viscosity of the resin, the smaller the friction force, so the moving distance of the detection plate 11 is closer. After pre-detection, when the detection plate 11 is in a certain position range, it is the optimal range of resin viscosity. The detection plate 11 in this range will drive the second permanent magnet 12 to be synchronously in the position range. At the same time, the second permanent magnet 12 will drive the conductive sheet 13 to be in a certain range of the resistor plate 14. Therefore, the current monitor in the PLC controller records the range of the current passing through the sliding rheostat within the above range. When the viscosity of the resin increases, the detection plate 11 will be driven to move excessively to the side away from the connection spring 112, thereby driving the conductive sheet 13 to slide excessively on the resistance plate 14, and finally causing the current passing through the sliding rheostat to increase. When the current exceeds the pre-detected current, the current channel between the sliding rheostat and the electromagnetic block 152 will be opened through the PLC controller, thereby increasing the current passing through the electromagnetic block 152. By increasing the current passing through the electromagnetic block 152, the electromagnetic block 152 will increase the repulsive force on the permanent magnet block 154, thereby causing the heating rod 16 to move downward. When the heating plate moves downward, it will move downward through the blocking ring 156, and then the air in the heating chamber 158 will be extracted through the pressure control port 1512, and then the conductive ring 1510 will move upward, thereby increasing the resistance length of the resistor rod 159, thereby increasing the resistance and the heating temperature. Since the heating rod 16 moves downward and the heating temperature increases at the same time, the heat is quickly transferred to the resin through the heat conducting plate 157, and the resin viscosity is reduced by heating the resin. The reason is that when the resin is heated, the kinetic energy of the molecules increases, and the movement between the molecules becomes more intense. This intense movement increases the distance between the molecules and weakens the attraction between the molecules, thereby restoring the resin to the optimal viscosity.

[0031] At the same time, the extrusion plate 21 is limited by the threaded rod 18 and the multi-stage telescopic shell 22, so that the extrusion plate 21 moves up and down. The extrusion plate 21 moves downward, and then the gas vent 23 in the reaction tube 3 enters the multi-stage telescopic shell 22. At the same time, the infrared rangefinder composed of the infrared transmitter 215 and the infrared receiver 216 detects the distance of the extrusion plate 21. When it is detected that the extrusion plate 21 moves upward, the first water pump 212 is controlled by the PLC controller to pump out the clean water in the clean water tank 210, and then discharge it into the water spray head 24. The gas entering the multi-stage telescopic shell 22 is sprayed by the water spray head 24. When the thermistor 25 feels the heat change after spraying, it indicates that the resin produces hydrogen halide gas during the reaction process. The reason is that when the hydrogen halide gas contacts water, it will quickly dissolve and dissociate to generate hydrogen ions and halogen ions. In this process, strong ion-dipole interactions and hydrogen bonds are formed between hydrogen halide molecules and water molecules, resulting in the release of energy. At the same time, the generated hydrogen ions will combine with water molecules to form hydronium ions. This process also releases heat. Therefore, the entire dissolution process is exothermic. The reason for the generation of hydrogen halide gas is that the formation process of N-halamine resin usually involves the reaction of halogens (such as chlorine and bromine) with amine groups. Such reactions often generate hydrogen halide (HCl, HBr, etc.). Hydrogen halide is a strong acid, which will gradually dissolve in the reaction system, thereby increasing the acidity of the solution. When the resin is in acidic conditions, side reactions will occur, so it needs to be adaptively adjusted to alkalinity. When the resistance change of thermistor 25 is too large, it proves that the concentration of hydrogen halide gas is too high, so the heat release is too large, and the environment of the resin is acidic. Therefore, it is necessary to control the flow solenoid valve 29 to open through the PLC controller, and then the PLC controller determines the dosage of alkaline solution to be added according to the current passing through the thermistor 25, and then transmits it to the flow solenoid valve 29. When the alkaline solution in the liquid storage chamber 27 is discharged from the alkaline container through the liquid outlet pipe 28, the flow solenoid valve 29 is closed by the PLC controller.

[0032] When the extrusion plate 21 moves upward, the outside air is transmitted to the reaction tube 3 through the ventilation pipe 26, thereby preventing negative pressure in the reaction tube 3, and the second water pump 213 is started by the PLC controller to pump out the waste water in the multi-stage telescopic shell 22 through the second water pump 213 and then discharge it into the recovery box 211.
