Description

Technical Field

[0001] The invention belongs to the field of phthalocyanine blue pigment preparation, in particular to an automatic control reaction kettle for preparing phthalocyanine blue pigment. Background Art

[0002] Reactors are commonly used containers for chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and low-speed mixing functions required by the process are realized. Reactors are widely used and are pressure vessels used to complete processes such as sulfidation, nitration, hydrogenation, hydrocarbonization, polymerization, and condensation.

[0003] Phthalocyanine blue is an organic substance with the chemical formula C32H16CuN8. It is a brilliant green blue rod-shaped crystal. It is flammable, insoluble in water, alcohol and hydrocarbons. It is soluble in concentrated sulfuric acid to form an olive-colored solution. After dilution, a blue suspension is precipitated in phthalonitrile in sodium amyl alcohol medium. It is heated at 125°C to form sodium phthalocyanine. After drying, it is treated with methanol at 10°C to transform into metal-free phthalocyanine. It is used for coloring automotive paints and art pigments, and is also used as some high-end colorants that do not contain metals. The entire reaction process often requires the participation of a reactor.

[0004] When preparing phthalocyanine blue pigment, it is necessary to add a variety of raw materials into a reactor, and control the temperature for stirring and temperature-controlled mixing. At the same time, it is necessary to use tetrahydrofuran and other solutions to allow the various raw materials to fuse and react with each other. The final judgment of the phthalocyanine blue pigment product not only requires strict compliance with the operating procedures and precise reaction time, but each chemical reaction will have variables due to minor reasons. Therefore, in order to determine whether the phthalocyanine blue pigment is finally qualified, it is necessary to take out some phthalocyanine blue pigment and observe whether its color meets the standard. Traditional reactors are integrally formed, and color confirmation can only be achieved by discharging the material from the bottom or observing through the upper observation mirror.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0022] Embodiment 1: Figures 1 to 4As shown, an automatic control reactor for preparing phthalocyanine blue pigment described in an embodiment of the present invention comprises a reactor body 1, a reduction motor 2 is fixedly connected to the top of the reactor body 1, a bottom output end of the reduction motor 2 passes through the top of the reactor body 1 and is fixedly connected to a stirring rod 7, two symmetrically arranged stirring frames 8 are fixedly connected to the outer side of the stirring rod 7 near the bottom end, a discharge valve 11 connected to the reactor body 1 is fixedly connected to the middle of the bottom end of the reactor body 1, a flushing groove 9 is provided on the inner side of the stirring rod 7, the top and bottom ends of the flushing groove 9 are both located on the outer side of the stirring rod 7, and the stirring rod 7 is fixedly connected to the bottom end of the stirring rod 7. The outer side is rotatably connected with a fixing ring 13, and the fixing ring 13 is at the same height as the top of the flushing tank 9. The outer side of the fixing ring 13 is provided with an extraction detection component, which is used to provide negative pressure to extract the liquid from the kettle body 1 and detect it. During operation, when preparing phthalocyanine blue pigment, it is necessary to add a variety of raw materials into the reactor, and control the temperature for stirring and temperature control mixing. At the same time, it is necessary to cooperate with tetrahydrofuran and other solutions to allow various raw materials to fuse and react with each other. The final judgment of the phthalocyanine blue pigment product not only requires strict compliance with the operating steps and accurate reaction time, but each chemical reaction will have variables due to minor reasons. Therefore, in order to determine whether the phthalocyanine blue pigment is finally qualified, it is necessary to take out part of the phthalocyanine blue pigment and observe whether its color meets the standard. The traditional reactor is integrally formed, and the color confirmation can only be confirmed by discharging from the bottom or observing from the upper observation mirror. The former has too many steps, and because the reactor body 1 is large, it is easy to control the amount of discharge. The latter has too low observation accuracy. Through the setting of the fixing ring 13, as the reduction motor 2 drives the stirring rod 7 and the stirring frame 8 to stir, the extraction detection component is provided to generate Negative pressure is transmitted to the fixed ring 13. The connecting groove 21 in the stirring rod 7 is connected with the solution inside the kettle body 1. When the fixed ring 13 generates negative pressure, part of the liquid in the kettle body 1 can be drawn into the fixed ring 13 through the connecting groove 21, and finally flows into the extraction and detection component. This setting can extract part of the solution in real time for color judgment. The amount of extraction depends on the size of the negative pressure, and there will not be too much problem. The fixed ring 13 is rotatably connected to the stirring rod 7. When the stirring rod 7 rotates, the fixed ring 13 is stationary, and the stirring rod 7 will not affect the extraction work of the fixed ring 13.

[0023] like Figure 3 to Figure 4As shown, the extraction detection component includes a transmission tube 14, which passes through the outside of the kettle body 1 and is fixedly connected to the kettle body 1. The fixed ring 13 is opened at one end facing the stirring rod 7, and the transmission tube 14 is connected to the fixed ring 13. The end of the transmission tube 14 away from the fixed ring 13 is connected to the negative pressure module. The transmission tube 14 is located on the outside of the kettle body 1 and is made of transparent glass. When working, the negative pressure module provides negative pressure to the transmission tube 14 to extract part of the liquid in the kettle body 1. When the liquid moves to the glass material part of the transmission tube 14, the negative pressure transmission is closed, and the extracted solution can be viewed from the outside. Through this arrangement, the color of the product in the reaction can be effectively and accurately observed to ensure the final quality of the product. Moreover, the solution will fall back into the kettle body 1 under the action of gravity by simply removing the negative pressure, which is convenient for recycling.

[0024] like Figure 3 to Figure 4 As shown, a split observation tube 15 is connected between the transmission tube 14 and the negative pressure module. The split observation tube 15 is composed of a plurality of glass tubes, which are arranged in parallel and equidistantly. A merging tube is fixedly connected to one end of the plurality of glass tubes, and the merging tube is connected to the transmission tube 14. An optical detection module is arranged on the outside of the plurality of glass tubes. The optical detection module is used to detect the color of the outside of the glass tubes. During operation, when the extracted solution moves outward with the transmission tube 14 and encounters the split observation tube 15, it will be equally divided into multiple tubes of liquid by the equally divided glass tubes. This arrangement can observe the color of the product more clearly, and if the solution is unevenly mixed, the colors in the plurality of glass tubes will be different. Therefore, this structure also has the effect of detecting whether the product is evenly mixed. The observation method of the split observation tube 15 can be detected by the human eye or by an optical detection module.

[0025] like Figure 3 to Figure 4 As shown, one end of the multiple glass tubes away from the transmission tube 14 is connected to a transfer box 6, and the transfer box 6 is connected to a negative pressure module. A solenoid valve is provided in the middle of the inner side of the transfer box 6, and a flushing tube is connected to the top of the transfer box 6. The flushing tube is located between the glass tubes and the solenoid valve. When working, the negative pressure is transferred to the splitting observation tube 15 through the setting of the transfer box 6. After the multiple glass tubes are filled, the glass tubes and the negative pressure module are closed by the solenoid valve to allow the inhaled solution to stay in the glass tubes. After the negative pressure is relieved, a cleaning solution is flushed into the glass tubes through the flushing tube. The solution does not react with the product and will be removed in the distillation step later.

[0026] like Figures 2 to 6As shown, a plurality of flushing grooves 9 are provided on the outer side of the stirring rod 7, and the flushing grooves 9 are connected to the connecting grooves 21, and a one-way valve is fixedly connected to the middle of the flushing grooves 9. The end of the transmission tube 14 away from the fixing ring 13 is estimated to have a conversion cylinder 17, and the end of the conversion cylinder 17 away from the transmission tube 14 is connected to the withdrawal tank 5 and the extraction tank 16, and the splitting observation tube 15 is also connected to the conversion cylinder 17. A switching component is provided on the inner side of the conversion cylinder 17, and the switching component is used to switch the connecting path. When working, after all the products are discharged, a large amount of solution will be attached to the inner wall of the kettle body 1 and the outer side of the stirring frame 8, and the solution will be directly Negative pressure is drawn inside the kettle body 1, and the bottom of the suction tank 5 is connected to cleaning water, which passes through the transmission pipe 14, the fixing ring 13 and the connecting groove 21, and is finally sprayed out from the multiple flushing grooves 9, thereby effectively cleaning the inner wall of the kettle body 1 and the product residue on the outside of the stirring frame 8. Compared with the traditional kettle washing, it is more thorough and clean. The setting of the one-way valve prevents the sucked negative pressure from acting on the connecting groove 21. The setting of the extraction tank 16 can extract more products from the stirred kettle body 1, and measure the color strength and compatibility thereof, so as to further ensure the quality evaluation of the product manufacturing process, and the switching component is used to switch the connection between the three.

[0027] like Figure 5 As shown, the switching assembly includes a fixed disk 18, and the surface of the fixed disk 18 is provided with three circular holes that penetrate the fixed disk 18, and the three circular holes are arranged in a ring shape. A driving motor 20 is arranged on the outer side of the conversion cylinder 17, and the output end of the driving motor 20 passes through the conversion cylinder 17 and the fixed disk 18, and is fixedly connected with a rotating disk 19. The diameter of the rotating disk 19 is the same as that of the fixed disk 18, and the surface of the rotating disk 19 is provided with a flow hole with the same diameter as the circular hole. The rotating disk 19 and the fixed disk 18 are movably fitted. When working, the rotating disk 19 is driven by the driving motor 20 to rotate. As the rotating disk 19 rotates, the flow hole and the circular hole are connected, so that the transmission pipe 14 can be connected to the structure that needs to be connected. Through this arrangement, compared with setting three control valves, the operation is simpler, and there is a single connectivity, and only one of them can be connected, which reduces mutual influence.

[0028] like Figures 1 to 4 As shown, a plurality of transfer valves 3 are fixedly connected to the outer side of the kettle body 1, a plurality of support frames 4 for supporting the kettle body 1 are fixedly connected to the outer side of the kettle body 1, the transfer box 6 is fixedly connected to the drive motor 20, the bottom of the recycle tank 5 is fixedly connected to the extension pipe, the bottom of the extraction tank 16 is connected to the negative pressure module, and the top of the outer side of the extraction tank 16 is fixedly connected to the extension pipe. During operation, when mixing is carried out inside the kettle body 1, it is necessary to continuously extract the treated solution from other reactors and finally transfer the finished product away. Through the setting of multiple feed valves 10 and discharge valves 11, multiple feed valves 10 are used to feed materials into the kettle body 1, and the discharge valve 11 is used to finally transfer the materials away, without the need to continuously replace the connecting pipe.

[0029] like Figures 2 to 7 As shown, a plurality of feed valves 10 are fixedly connected to the top of the outer side of the kettle body 1, and the plurality of feed valves 10 are arranged in a ring shape. An operating tube 12 is fixedly connected to the input end of one of the feed valves 10, and a plurality of magnet blocks 23 are arranged on the outer side of the operating tube 12. When working, during the reaction process, it is sometimes necessary to transport a 500 ml solution barrel from the outside, and draw the solution in the barrel into the kettle body 1, and extract the liquid through a dedicated operating tube 12. At the same time, the arrangement of the magnet block 23, since the outer surface of the kettle body 1 is made of metal material, the operating tube 12 is fixed to the surface of the reactor through adsorption by the magnet block 23.

[0030] like Figure 7 As shown, the end of the operating tube 12 is fixedly connected with an anti-slip sleeve, and the outer side of the operating tube 12 is slidably connected with a wrapping ring 22. The outer side of the wrapping ring 22 is provided with an adsorption component, and the adsorption component is used to adsorb the wrapping ring 22 to the outside of the hole. During operation, when the operating tube 12 absorbs the solution, the mouth of the barrel and the operating tube 12 generally cannot be completely fitted together. The commonly used solutions in production, such as tetrahydrofuran, are not only highly volatile, but also have certain toxicity. Through the setting of the adsorption component, when the operating tube 12 is inserted into the solution in the barrel, the adsorption component will adsorb the wrapping ring 22 at the barrel mouth and fill the gap between the barrel mouth and the operating tube 12 to reduce the volatilization of the solution. The setting of the anti-slip sleeve can prevent the wrapping ring 22 from falling off the operating tube 12.

[0031] Embodiment 2: Figure 7 As shown, compared with Example 1, another embodiment of the present invention is: the adsorption component includes a fitting ring 24, the inner diameter of the fitting ring 24 is the same as the outer side of the operating tube 12, the fitting ring 24 is fixed to the inner ring of the wrapping ring 22, the fitting ring 24 is a solid material, and the outer surface of the fitting ring 24 is fixed with an adsorption motor, the interior of the wrapping ring 22 is hollow, and the wrapping ring 22 is an elastic material, a plurality of magnet blocks 23 are arranged in a ring shape and fixed to the outer side of the wrapping ring 22, and the magnet blocks 23 are located on the side away from the fitting ring 24. When working, the fitting ring 24 allows the wrapping ring 22 to always fit the surface of the operating tube 12, and the wrapping ring 22 is fixed to the outer side of the wrapping ring 22. The ring 22 is initially close to the anti-dropping sleeve. With the negative pressure in the kettle body 1, the operating tube 12 generates negative pressure. As the operating tube 12 is inserted into the barrel mouth and extends into the solution, the wrapping ring 22 will stay outside the hole. The wide and elastic wrapping ring 22 will fill the gap in the barrel mouth under pressure. At the same time, since the liquid in the barrel is absorbed by the negative pressure at this time, the barrel is in a negative pressure state, which will squeeze the elastic hollow wrapping ring 22 inward to ensure the sealing of the barrel mouth. At the same time, the magnet block 23 will absorb the metal barrel. When the absorption is completed, the operating tube 12 is pulled out. Under the adsorption of the magnet block 23, the operating tube 12 slides relative to the fitting ring 24, and the chemical solution on the surface of the operating tube 12 can be cleaned.

[0032] During work, when preparing phthalocyanine blue pigment, it is necessary to add a variety of raw materials into the reactor, and control the temperature for stirring and temperature-controlled mixing. At the same time, it is necessary to use tetrahydrofuran and other solutions to allow the various raw materials to fuse and react with each other. The final judgment of the finished phthalocyanine blue pigment not only requires strict follow-up of the operating steps and accurate reaction time, but each chemical reaction will have variables due to minor reasons. Therefore, in order to determine whether the phthalocyanine blue pigment is finally qualified, it is necessary to take out some phthalocyanine blue pigment to observe whether its color meets the standard. The traditional reactor is integrally formed, and the color can only be confirmed by discharging the material at the bottom or observing it through the observation mirror above. The former has too many steps, and because the reactor is large in size, It is easy to control the amount released poorly, and the latter observation accuracy is too low. Through the setting of the fixed ring 13, as the reduction motor 2 drives the stirring rod 7 and the stirring frame 8 to stir, the negative pressure is generated by providing a negative pressure through the extraction detection component, and the negative pressure is transmitted to the fixed ring 13. The connecting groove 21 in the stirring rod 7 is connected to the solution inside the kettle body 1. When the fixed ring 13 generates negative pressure, part of the liquid in the kettle body 1 can be drawn into the fixed ring 13 through the connecting groove 21, and finally flows into the extraction detection component. This setting can extract part of the solution in real time for color judgment. The amount of extraction depends on the size of the negative pressure, and there will not be too much problem. The fixed ring 13 rotates with the stirring rod 7. The stirring rod 7 is dynamically connected, and the fixing ring 13 is stationary when the stirring rod 7 rotates, and the stirring rod 7 will not affect the extraction work of the fixing ring 13; the negative pressure module provides negative pressure to the transmission tube 14 to extract part of the liquid in the kettle body 1. When the liquid moves to the glass material part of the transmission tube 14, the negative pressure transmission is closed, and the extracted solution can be observed from the outside. Through this setting, the color of the product in the reaction can be effectively and accurately observed to ensure the final quality of the product, and only the negative pressure needs to be released, and the solution will fall back into the kettle body 1 under the action of gravity, which is convenient for recycling; when the extracted solution moves outward with the transmission tube 14, when it encounters the split observation tube 15, it will be equally divided into multiple tubes of liquid by the equally divided glass capillaries This arrangement can more clearly observe the color of the product, and if the solution is not mixed evenly, the colors in the multiple glass tubes will be different. Therefore, this structure also has the effect of detecting whether the product is mixed evenly. The observation method of the split observation tube 15 can be detected by human eyes or by an optical detection module; through the setting of the transfer box 6, the negative pressure is transmitted to the split observation tube 15. When the multiple glass tubes are filled, the glass tubes and the negative pressure module are closed by the solenoid valve to allow the inhaled solution to stay in the glass tubes. When the negative pressure is removed, the cleaning solution is flushed into the glass tubes through the flushing tube. The solution does not react with the product and will be removed in the distillation step later;After all the products are discharged, a large amount of solution will be attached to the inner wall of the kettle body 1 and the outer side of the stirring frame 8. By directly pumping negative pressure on the inner side of the kettle body 1, the bottom of the suction tank 5 is connected to the cleaning water, and the cleaning water passes through the transmission pipe 14, the fixing ring 13 and the connecting groove 21, and finally sprayed out from the multiple flushing grooves 9, so as to effectively clean the inner wall of the kettle body 1 and the outer side of the stirring frame 8. Compared with the traditional kettle washing, it is more thorough and clean. The setting of the one-way valve makes the sucked negative pressure not act on the connecting groove 21. The setting of the extraction tank 16 can extract more products from the stirring kettle body 1, and measure the coloring strength and compatibility thereof, so as to further ensure the quality evaluation of the product manufacturing process, and the switching component is used to switch the connection between the three; the turntable 19 is driven by the driving motor 20 to rotate. As the turntable 19 rotates, the flow hole and the circular hole are connected, so that the transmission pipe 14 can be connected to the structure that needs to be connected. Through this setting, compared with setting three control valves, the operation is simpler, and there is a single connectivity, only one of them can be connected, which reduces mutual influence; the inside of the kettle body 1 is When mixing, it is necessary to continuously extract the processed solution from other reactors and transfer the finished product away at the end. Through the setting of multiple feed valves 10 and discharge valves 11, multiple feed valves 10 are used to feed the material into the reactor body 1, and the discharge valve 11 is used to finally transfer the material away, without constantly replacing the connecting pipe; during the reaction process, it is sometimes necessary to transport a 500 ml solution barrel from the outside, and draw the solution in the barrel into the reactor body 1, and extract the liquid through a dedicated operating pipe 12. At the same time, the setting of the magnetic block 23, because the surface of the reactor body 1 is made of metal The operating tube 12 is fixed on the surface of the reactor by adsorption of the magnet block 23; when the operating tube 12 absorbs the solution, the barrel mouth and the operating tube 12 generally cannot be completely fitted, and the commonly used solutions in production, such as tetrahydrofuran, are not only highly volatile, but also have certain toxicity. Through the setting of the adsorption component, when the operating tube 12 is inserted into the solution in the barrel, the adsorption component will adsorb the wrapping ring 22 at the barrel mouth and fill the gap between the barrel mouth and the operating tube 12, reducing the volatilization of the solution. The setting of the anti-slip sleeve can prevent the wrapping ring 22 from falling out of the operating tube 12. ;
