Description

Technical Field

[0001] The invention relates to the technical field of hydrothermal reactors, in particular to a temperature-controlled high-pressure reactor. Background Art

[0002] Hydrotalcite and hydrotalcite-like compounds are collectively called layered double hydroxides (LDH). They can not only effectively hinder the damage of corrosive media to the substrate through a good physical barrier effect, but also their good anion exchange performance can fix corrosive anions in the LDH layer, preventing them from further contacting the substrate and causing corrosion. Therefore, LDH film has received widespread attention in the field of magnesium alloy corrosion protection.

[0003] In the prior art, when preparing LDH membrane, a mixed solution of Mg(NO3)2·6H2O, Al(NO3)3·9H2O and aspartic acid (ASP) and a magnesium alloy are usually transferred into a hydrothermal reactor, and then hydrothermally reacted at 120°C for 9 hours to prepare a Mg-Al-ASP LDH membrane, and the effect of the hydrothermal reaction time on the corrosion resistance of the resulting film layer is studied.

[0004] In the above-mentioned process of preparing LDH membrane by hydrothermal reaction method, a hydrothermal reactor is usually used. The hydrothermal reactor is one of the important equipment for high-temperature and high-pressure reactions in the laboratory. Its main principle is to use the high pressure and high temperature of water to promote the reaction rate and ensure the selectivity and yield of the reaction. Due to the extremely harsh reaction conditions, the operator must have rich experimental experience and a high sense of safety. In actual use, the reaction materials in the reactor will generate huge pressure at high temperature, and the user is usually unable to determine the magnitude of this pressure. Forcing it to open can easily lead to a safety accident of explosion of the hydrothermal reactor. In addition, the reactor is placed inside the heating device and temperature control is required. Excessive temperature is not only unhelpful in shortening the hydrothermal reaction time of the LDH membrane, but also causes the pressure in the reactor to continue to increase. Once the threshold is exceeded, the reactor shell may break or even explode.

[0005] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a temperature-controlled high-pressure reactor is proposed. Summary of the invention

[0006] The object of the present invention is to provide a temperature-controlled high-pressure reactor to solve the problems raised in the above background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a temperature-controlled high-pressure reactor, comprising a reactor body and a pressure monitoring component, the top opening of the reactor body is provided with a threaded opening, and the pressure monitoring component is fixed to the top of the reactor body by bite, and the pressure monitoring component comprises a reactor cover, screw threads, bosses, through holes, booster rods, embedded grooves, valve needles, limit plates and springs. The inner wall of the reactor cover is provided with screw threads, and the reactor cover is fixed to the threaded opening of the top opening of the reactor body by the screw threads. The top of the reactor cover is integrally fixed with a boss, and a through hole is penetrated in the middle of the boss, and a booster rod is inserted in the through hole. The middle of the reactor cover is provided with an embedded groove, and a valve needle is slidably installed in the embedded groove. The middle of the valve needle is integrally fixed with a limit plate, and a spring is elastically connected above the limit plate.

[0008] Furthermore, a heat-conducting gasket is arranged at the bottom of the kettle body, a bushing is placed inside the kettle body, and a lining cover is interference-fitted at the top opening of the bushing.

[0009] Furthermore, a notch is provided in the middle of the liner cover, and a pressure diaphragm is fixed at the opening of the notch by screws. The pressure diaphragm bulges as the internal pressure of the bushing increases, and the bulging pressure diaphragm drives the valve needle located inside the through hole to rise.

[0010] Furthermore, the kettle body is placed inside the electric furnace, and a spiral heating wire is arranged in the interlayer of the inner wall of the electric furnace. A supporting ring is fixed to the bottom of the inner wall of the electric furnace, and the supporting ring is connected to the bottom plane of the kettle body.

[0011] Furthermore, a temperature monitoring component is provided at the bottom end of the electric furnace, and the temperature monitoring component includes a substrate, a card block and a butterfly-shaped metal sheet. A card block is fixed on the left side of the bottom of the substrate, and a butterfly-shaped metal sheet is engaged inside the card block. The butterfly-shaped metal sheet is formed by stacking two metals with different thermal expansion coefficients, and when the execution temperature is reached, the butterfly-shaped metal sheet bends and deforms toward the side with a lower thermal expansion coefficient.

[0012] Furthermore, the temperature monitoring component also includes a bearing seat and a rotating plate. The bearing seats are fixed on both sides of the top of the base plate, and a rotating plate rotates inside the bearing seat.

[0013] Furthermore, the temperature monitoring component also includes a second spring and a trigger rod, the shorter resistance arm on one side of the rotating plate is elastically connected to the second spring, and the longer power arm on the other side of the rotating plate is fixedly connected to the trigger rod.

[0014] Furthermore, a temperature control component is arranged on the outside of the side of the electric furnace, and the temperature control component includes a controller and a wire node. A wire node is arranged at the rear end of the controller, and the wire node cooperates with a resistance arm on one side of the rotating plate to control on and off.

[0015] Furthermore, the temperature control component also includes a display panel, a power interface and a regulating knob. A display panel is arranged on the top of the front end of the controller, and a power interface is arranged on one side of the front end of the controller. The power interface is connected to the AC power and supplies power to the heating wire through a wire node. A regulating knob is arranged on the other side of the front end of the controller, and the regulating knob controls the heating power of the heating wire through a sliding rheostat.

[0016] Furthermore, the temperature control component also includes a signal line and a temperature sensor. The top of the controller is externally connected to a signal line, and the end of the signal line is electrically connected to a temperature sensor, and the temperature sensor is attached to the inner wall of the bottom end of the electric furnace.

[0017] The present invention provides a temperature-controlled high-pressure reactor, which has the following beneficial effects:

[0018] 1. During the use of the present invention, on the one hand, a pressure diaphragm is fixed to the middle recess of the liner cover by screws, and the pressure diaphragm bulges as the internal pressure of the liner increases. The further bulging pressure diaphragm drives the valve needle to rise inside the through hole, so that the head of the valve needle protrudes from the through hole in the middle of the boss, preventing the user from inserting the booster rod into the through hole in an attempt to open the kettle cover when the pressure is too high. The above-mentioned fool-proof design can prevent the operator from forcibly opening the kettle cover due to lack of experience, resulting in an explosion. When the pressure in the liner returns to normal, the valve needle resets under the action of the reset force of spring 1. At this time, the operator can normally insert the booster rod into the through hole to open the kettle cover and take out the final product, giving the hydrothermal reactor of the present application an excellent explosion-proof function.

[0019] 2. During the use of the present invention, on the other hand, when the temperature inside the kettle exceeds the design threshold and reaches the execution temperature of the butterfly-shaped metal sheet, the butterfly-shaped metal sheet in the bottom block of the substrate is deformed by heat. The butterfly-shaped metal sheet of the present application is formed by stacking two metals with different thermal expansion coefficients. When the execution temperature is reached, the butterfly-shaped metal sheet bends and deforms toward the side with a lower thermal expansion coefficient. The trigger rod on one side of the rotating plate power arm in the bearing seat is lifted by the butterfly-shaped metal sheet, overcoming the elastic force of spring 2 to cause the rotating plate to deflect, thereby causing the resistance arm side to trigger the wire node at the rear end of the controller, disconnecting the path of the heating wire to stop heating, preventing the temperature from rising and causing the pressure in the kettle to increase, thereby inducing an explosion accident, and giving the hydrothermal reactor of the present application a temperature control function.

[0020] 3. During the use of the present invention, first, the reaction materials and the solvent of the reaction kettle are poured into the bushing and covered with the liner, then the bushing is placed in the kettle body, and the inner wall screw thread of the kettle cover is tightened and fixed with the threaded mouth on the top of the kettle body. During this process, the booster rod can be inserted into the through hole in the middle of the boss to assist in applying force to ensure fastening, and finally the kettle body is placed in an electric furnace. The power interface on one side of the controller is connected to the mains and supplies power to the heating wire through the wire node. The kettle body is evenly heated by the spiral heating wire arranged in the interlayer of the inner wall of the electric furnace, and the solvent in the kettle body is heated and evaporated, so that the internal air pressure increases, and the preparation process of the LDH membrane is completed under a certain temperature and pressure environment. During use, the control knob on the other side of the controller controls the heating power of the heating wire through a sliding rheostat to achieve regulation of the reaction temperature.

The middle of the valve needle 807 is fixed with a limit plate 808 in an integral manner, and the upper part of the limit plate 808 is elastically connected with a spring 1 809;

[0032] The specific operation is as follows. On the one hand, the notch 6 in the middle of the lining cover 5 is fixed with a pressure diaphragm 7 by screws. The pressure diaphragm 7 bulges as the internal pressure of the lining 4 increases. The further bulging pressure diaphragm 7 drives the valve needle 807 to be located inside the through hole 804 and lift up, so that the head of the valve needle 807 protrudes from the through hole 804 in the middle of the boss 803, preventing the user from inserting the booster rod 805 into the through hole 804 in an attempt to open the kettle cover 801 when the pressure is too high.

[0033] See also Figure 6 to Figure 7 The kettle body 1 is placed inside the electric furnace 9, and a spiral electric heating wire 10 is arranged in the inner wall interlayer of the electric furnace 9, a support ring 11 is fixed to the bottom of the inner wall of the electric furnace 9, and the support ring 11 is connected to the bottom plane of the kettle body 1, and a temperature monitoring component 12 is arranged at the bottom end of the electric furnace 9. The temperature monitoring component 12 includes a base plate 1201, a block 1202 and a butterfly-shaped metal sheet 1203. A block 1202 is fixed to the left side of the bottom of the base plate 1201, and a butterfly-shaped metal sheet 1203 is clamped inside the block 1202. The butterfly-shaped metal sheet 1203 is laminated by two metals with different thermal expansion coefficients.

The bearing seats 1204 are fixed on both sides of the top of the base plate 1201, and the rotating plate 1205 rotates inside the bearing seat 1204. The temperature monitoring assembly 12 also includes a spring 1206 and a trigger rod 1207. The shorter resistance arm on one side of the rotating plate 1205 is elastically connected to the spring 1206, and the longer power arm on the other side of the rotating plate 1205 is fixedly connected to the trigger rod 1207.

[0034] The specific operation is as follows. On the other hand, when the temperature in the kettle body 1 exceeds the design threshold and reaches the execution temperature of the butterfly-shaped metal sheet 1203, the butterfly-shaped metal sheet 1203 in the bottom block 1202 of the substrate 1201 is deformed by heat. The butterfly-shaped metal sheet 1203 of the present application is formed by stacking two metals with different thermal expansion coefficients. When the execution temperature is reached, the butterfly-shaped metal sheet 1203 bends and deforms toward the side with a lower thermal expansion coefficient. The trigger rod 1207 on the power arm side of the rotating plate 1205 in the bearing seat 1204 is lifted by the butterfly-shaped metal sheet 1203, overcoming the elastic force of the second spring 1206 to deflect the rotating plate 1205, thereby causing the wire node 1302 at the rear end of the controller 1301 to be triggered on one side of the resistance arm, disconnecting the passage of the heating wire 10 to stop heating, preventing the temperature from rising and causing the pressure in the kettle body 1 to increase, thereby inducing an explosion accident, and giving the hydrothermal reactor of the present application a temperature control function;

[0035] See also Figure 8 A temperature control component 13 is arranged on the outside of the side of the electric furnace 9, and the temperature control component 13 includes a controller 1301 and a wire node 1302. The wire node 1302 is arranged at the rear end of the controller 1301, and the wire node 1302 cooperates with the resistance arm on one side of the rotating plate 1205 to control the on-off. The temperature control component 13 also includes a display panel 1303, a power interface 1304 and a regulating knob 1305. The display panel 1303 is arranged on the top of the front end of the controller 1301, and the power interface 1304 is arranged on one side of the front end of the controller 1301, and The power interface 1304 is externally connected to the mains and supplies power to the heating wire 10 through the wire node 1302. A regulating knob 1305 is provided on the other side of the front end of the controller 1301, and the regulating knob 1305 controls the heating power of the heating wire 10 through a sliding rheostat. The temperature control component 13 also includes a signal line 1306 and a temperature sensor 1307.

[0036] The specific operation is as follows: the power interface 1304 on one side of the controller 1301 is connected to the AC power and supplies power to the heating wire 10 through the wire node 1302. The spiral heating wire 10 arranged in the inner wall interlayer of the electric furnace 9 makes the kettle body 1 evenly heated, and the solvent in the kettle body 1 evaporates due to the heat, so that the internal air pressure increases, and the preparation process of the LDH membrane is completed under a certain temperature and pressure environment. During use, the control knob 1305 on the other side of the controller 1301 controls the heating power of the heating wire 10 through a sliding rheostat to achieve regulation of the reaction temperature.

[0037] In summary, when using the temperature-controlled high-pressure reactor, first pour the reaction materials and the reactor solvent into the bushing 4 and cover it with the liner 5, then put the bushing 4 into the reactor body 1, and tighten the inner wall screw thread 802 of the reactor cover 801 with the threaded opening 2 on the top of the reactor body 1. During this process, the booster rod 805 can be inserted into the middle through hole 804 of the boss 803 to assist in applying force to ensure tightening, and finally put the reactor body 1 into the electric furnace 9, and the power interface 1304 on one side of the controller 1301 is connected to the mains and supplies power to the heating wire 10 through the wire node 1302.

During use, the control knob 1305 on the other side of the controller 1301 controls the heating power of the heating wire 10 through a sliding rheostat to achieve the regulation of the reaction temperature. On the one hand, the pressure diaphragm 7 is fixed to the recess 6 in the middle of the lining cover 5 by screws. The pressure diaphragm 7 bulges as the internal pressure of the lining 4 increases. The further bulging pressure diaphragm 7 drives the valve needle 807 to rise inside the through hole 804, so that the head of the valve needle 807 protrudes from the through hole 804 in the middle of the boss 803, preventing the user from pushing the booster rod 807 out of the through hole 804 in the middle of the boss 803 when the pressure is too high. 5 is inserted into the through hole 804 in an attempt to open the kettle cover 801. The above foolproof design can prevent the operator from forcibly opening the kettle cover 801 due to lack of experience, which may cause an explosion. When the pressure in the bushing 4 returns to normal, the valve needle 807 is reset under the reset force of the spring 1 809. At this time, the operator can normally insert the booster rod 805 into the through hole 804 to open the kettle cover 801 and take out the final product, giving the hydrothermal reactor of the present application an excellent explosion-proof function. On the other hand, when the temperature in the kettle body 1 exceeds the design threshold and reaches the execution temperature of the butterfly-shaped metal sheet 1203, the butterfly-shaped metal sheet 1203 in the clamping block 1202 at the bottom of the substrate 1201 is deformed by heat. The butterfly-shaped metal sheet 1203 of the present application is formed by stacking two metals with different thermal expansion coefficients. When the execution temperature is reached, the butterfly-shaped metal sheet 1203 bends and deforms toward the side with a lower thermal expansion coefficient. The trigger rod 1207 on the power arm side of the rotating plate 1205 in the bearing seat 1204 is lifted by the butterfly-shaped metal sheet 1203, overcoming the elastic force of the second spring 1206 to deflect the rotating plate 1205, thereby causing the wire node 1302 at the rear end of the controller 1301 to be triggered on one side of the resistance arm, disconnecting the passage of the heating wire 10 to stop heating, preventing the temperature from rising and causing the pressure in the kettle body 1 to increase, thereby inducing an explosion accident, giving the hydrothermal reactor of the present application a temperature control function.
