Description

Technical Field

[0001] The utility model relates to the field of experimental equipment, in particular to an experimental device which utilizes an electric field to control a reaction rate. Background Art

[0002] Experimental devices for controlling reaction rates by electric fields usually involve regulating the rate of chemical reactions by electric fields, which has important applications in chemical kinetics, materials science, electrochemical synthesis and other fields. Usually, the experimental device includes a reaction chamber, electrodes, power supplies, electric field regulation systems, monitoring systems, safety devices, etc. The working principle is: a sealed container is used as a reaction chamber to contain reactants and conduct chemical reactions, and then electrodes are installed in the reaction chamber (these electrodes can be metal or non-metal, and appropriate materials are selected as needed), and the power supply is connected to the power supply of the electrodes to generate and control the electric field, and then the electric field regulation system is used to adjust the voltage and current output by the power supply to control the intensity of the electric field, and finally a monitoring system such as sensors and data recording equipment is used to monitor the reaction rate and other related parameters.

[0003] Since the interior of the reaction container is sealed, if the temperature inside the reaction container is too high during the experiment, the internal pressure of the reaction container will be too high. If the pressurized gas is not discharged in time, it is easy to cause damage or explosion of the reaction container. The prior art uses a pressure relief valve to discharge the gas, and the released gas cannot be collected and stored. If the reaction material used in the experiment is a toxic chemical or can produce harmful by-products, the released gas will pose a risk to human health and the environment.

[0004] Therefore, it is necessary to invent an experimental device that uses electric field to control reaction rate. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an experimental device using electric field to control reaction rate, comprising a reaction container and an electrode, wherein the electrode is installed inside the reaction container, one end of the electrode is connected to a power line, a pressure relief pipe is installed on one side of the upper end of the reaction container, a sealing cover is installed on the outside of the pressure relief pipe, a gas storage component is arranged on one side of the reaction container, and guide components are symmetrically installed on both sides of the outer end of the gas storage component;

[0007] The gas storage assembly comprises a gas storage tank and a top cover arranged at the upper end of the gas storage tank, and a bellows is connected between the gas storage tank and the top cover.

[0008] Based on the above characteristics: if the pressure gas inside the reaction container is too large, the larger gas pressure can be released through the pressure relief pipe, and then the gas will flow into the sealing cover, and finally introduced into the gas storage assembly for storage, so as to avoid the reaction container from exploding or the leaked pressure gas from emitting into the surrounding air. The gas storage tank, top cover and bellows are an integrated structure. When more pressure gas is introduced into the gas storage assembly, the gas can lift the top cover upward. At this time, the top cover will stretch the bellows to expand the internal space of the gas storage assembly, so as to facilitate the storage of more gas. In the process of the top cover being lifted up, it will be positioned and guided by the guide assembly, so as to facilitate the top cover to pull the bellows to move vertically.

[0009] Preferably, a feed pipe is installed on one side of the upper end of the reaction container, a sealing cover is connected to the upper end of the feed pipe, and an agitator is arranged in the middle of the reaction container.

[0010] Based on the above features: open the sealing cover and feed the reactants into the reaction vessel through the feed tube. After the reactants are fed in, the sealing cover can be used to seal the feed tube, and the set agitator can stir the fed reactants to ensure that the reactants are evenly distributed in the reaction vessel, thereby improving the reaction efficiency.

[0011] Preferably, a positioning seat is provided at the upper end of the pressure relief pipe, a movable plug is fixedly installed at the lower end of the positioning seat, a ring-shaped array of through holes is opened on the surface of the movable plug, and a buffer spring is installed on the top of the positioning seat.

[0012] Based on the above characteristics: when the air pressure inside the reaction container is too high, the air pressure will push the movable plug upward through the pressure relief pipe. At this time, the movable plug will move up through the positioning seat to squeeze the buffer spring and deform. When the movable plug moves upward and leaks out of the through hole, the gas inside the reaction container will flow out through the pressure relief pipe and the through hole.

[0013] Preferably, a sealing ring is installed on the lower end surface of the positioning seat, and the sealing ring is located outside the movable plug.

[0014] Based on the above features: after the positioning seat moves downward, the sealing ring can perform sealing protection between the positioning seat and the pressure relief pipe to prevent gas leakage inside the reaction container when the reaction container does not need to release pressure.

[0015] Preferably, a gas pipe is fixedly installed on one side of the gas storage tank, one end of the gas pipe away from the gas storage tank is connected to the sealing cover, and a one-way valve is installed on the gas pipe.

[0016] Based on the above features: when the gas flows into the sealing cover through the through hole, the gas will be input into the gas storage tank through the gas pipe for storage, and the one-way valve is set to prevent the gas flowing into the gas pipe from flowing back.

[0017] Preferably, convex plates are fixedly mounted on both sides of the top cover, an exhaust pipe is mounted on the upper end of the top cover, and a sealing valve is mounted on the exhaust pipe.

[0018] Based on the above characteristics: if the collected gas is non-toxic and will not pollute the environment, the sealing valve can be opened to allow the gas to be discharged through the exhaust pipe.

[0019] Preferably, the guide assembly includes a base plate and a fixing rod fixedly installed on the upper end of the base plate, the upper end of the fixing rod is movably connected to a guide rod, and the upper end of the guide rod is fixedly connected to the convex plate.

[0020] Based on the above characteristics: when the amount of gas is too much and the top cover is lifted, the top cover will pull the guide rod upward through the convex plate. At this time, the fixed rod can guide and limit the guide rod, so that the guide rod and the top cover can maintain vertical movement.

[0021] The beneficial effects of the utility model are:

[0022] 1. It is convenient to automatically exhaust the gas when the pressure inside the reaction container is too large. When the pressure inside the reaction container is too large, the pressure gas will push up the movable plug through the pressure relief pipe. At this time, the movable plug will move up through the positioning seat to squeeze the buffer spring to deform. When the movable plug moves upward and leaks out of the through hole, the gas inside the reaction container will flow into the sealing cover through the pressure relief pipe and the through hole. Then the gas will be input into the gas storage tank through the gas pipe for storage, so as to prevent the reaction container from exploding or the leaked pressure gas from dissipating into the surrounding air.

[0023] 2. The gas tank, top cover and bellows are an integrated structure. When more pressurized gas is introduced into the gas storage assembly, the gas can push up the top cover. At this time, the top cover will stretch the bellows to expand the internal space of the gas storage assembly to facilitate the storage of more gas. In the process of the top cover being lifted up, the top cover will pull the guide rod upward through the convex plate. At this time, the fixed rod can guide the guide rod to limit the position, so that the guide rod and the top cover can maintain vertical movement. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0030] Refer to the attached Figure 1-4 The utility model provides an experimental device for controlling reaction rate by electric field, comprising a reaction vessel 1 and an electrode 2, wherein the electrode 2 is installed inside the reaction vessel 1, one end of the electrode 2 is connected to a power line 3, a pressure relief pipe 4 is installed on one side of the upper end of the reaction vessel 1, a sealing cover 5 is installed outside the pressure relief pipe 4, a gas storage component 6 is arranged on one side of the reaction vessel 1, and guide components 7 are symmetrically installed on both sides of the outer end of the gas storage component 6;

[0031] The gas storage assembly 6 includes a gas storage tank 61 and a top cover 62 disposed on the upper end of the gas storage tank 61 , and a bellows 63 is connected between the gas storage tank 61 and the top cover 62 .

[0032] One end of the power cord 3 is connected to the electrode 2, and the other end of the power cord 3 will be connected to the power supply and the electric field regulation system. Then the reactants are put into the reaction vessel 1 in advance. During the experiment, since the reaction vessel 1 is in a sealed state, if the pressure gas inside the reaction vessel 1 is too large during this process, the large air pressure can be relieved through the pressure relief pipe 4, and then the gas will flow into the sealing cover 5, and finally introduced into the gas storage component 6 for storage to prevent the reaction vessel 1 from exploding or the leaked pressure gas from emitting into the surrounding air. The gas storage tank 61, the top cover 62 and the bellows 63 are an integrated structure. When more pressure gas is introduced into the gas storage component 6, the gas can push up the top cover 62. At this time, the top cover 62 will stretch the bellows 63 to expand the internal space of the gas storage component 6 to facilitate the storage of more gas. In the process of the top cover 62 being lifted up, it will be positioned and guided by the guide component 7 to facilitate the top cover 62 to pull the bellows 63 to move vertically.

[0033] Preferably, a feed pipe 11 is installed on one side of the upper end of the reaction container 1 , a sealing cover 12 is connected to the upper end of the feed pipe 11 , and an agitator 13 is arranged in the middle of the reaction container 1 .

[0034] Open the sealing cover 12 and feed the reactants into the reaction vessel 1 through the feeding tube 11. After the reactants are fed, the feeding tube 11 can be sealed by the sealing cover 12, and the agitator 13 can stir the fed reactants to ensure that the reactants are evenly distributed in the reaction vessel 1 and improve the reaction efficiency.

[0035] Preferably, a positioning seat 41 is provided at the upper end of the pressure relief pipe 4 , a movable plug 42 is fixedly installed at the lower end of the positioning seat 41 , a through hole 43 in an annular array is opened on the surface of the movable plug 42 , and a buffer spring 44 is installed on the top of the positioning seat 41 .

[0036] When the air pressure inside the reaction vessel 1 is too high, the air pressure will push up the movable plug 42 through the pressure relief pipe 4. At this time, the movable plug 42 will move up through the positioning seat 41 to squeeze the buffer spring 44 and deform. When the movable plug 42 moves upward and leaks out of the through hole 43, the gas inside the reaction vessel 1 will flow out through the pressure relief pipe 4 and the through hole 43. When the air pressure inside the reaction vessel 1 is not enough to push up the movable plug 42, the buffer spring 44 will rebound the movable plug 42 so that the movable plug 42 is inserted into the pressure relief pipe 4. At this time, the through hole 43 will be located on the inner side of the pressure relief pipe 4, and the positioning seat 41 will seal the upper end of the pressure relief pipe 4.

[0037] Preferably, a sealing ring 411 is installed on the lower end surface of the positioning seat 41 , and the sealing ring 411 is located outside the movable plug 42 .

[0038] After the positioning seat 41 moves downward, the sealing ring 411 can perform sealing protection between the positioning seat 41 and the pressure relief pipe 4 to prevent gas leakage inside the reaction container 1 when the reaction container 1 does not need to be pressure-relieved.

[0039] Preferably, an air supply pipe 611 is fixedly installed on one side of the air storage tank 61 , one end of the air supply pipe 611 away from the air storage tank 61 is connected to the sealing cover 5 , and a one-way valve 612 is installed on the air supply pipe 611 .

[0040] When the gas flows into the sealing cover 5 through the through hole 43, the gas will be input into the gas storage tank 61 through the gas pipe 611 for storage, and the setting of the one-way valve 612 prevents the gas flowing into the gas pipe 611 from flowing back.

[0041] Preferably, convex plates 621 are fixedly mounted on both sides of the top cover 62 , an exhaust pipe 622 is mounted on the upper end of the top cover 62 , and a sealing valve 623 is mounted on the exhaust pipe 622 .

[0042] If the collected gas is non-toxic and will not pollute the environment, the sealing valve 623 can be opened to allow the gas to be discharged through the exhaust pipe 622.

[0043] Preferably, the guide assembly 7 includes a base plate 71 and a fixing rod 72 fixedly installed on the upper end of the base plate 71 , the upper end of the fixing rod 72 is movably connected to a guide rod 73 , and the upper end of the guide rod 73 is fixedly connected to the convex plate 621 .

[0044] When the amount of gas is too much and the top cover 62 is lifted, the top cover 62 will pull the guide rod 73 upward through the convex plate 621. At this time, the fixed rod 72 can guide and limit the guide rod 73, so that the guide rod 73 and the top cover 62 can keep moving vertically.

[0045] The use process of the utility model is as follows: during operation, one end of the power cord 3 is connected to the electrode 2, and the other end of the power cord 3 is connected to the power supply and the electric field regulation system. Then the reactants are put into the reaction container 1 in advance. At this time, the staff can apply an electric field between the electrodes 2 through the power supply (this electric field can be DC or AC, depending on the purpose of the experiment). Then the existence of the electric field causes the ions or polar molecules in the reactants to migrate, which can increase the collision frequency between the reactants. By changing the intensity and polarity of the electric field, the interaction between the reactants can be adjusted, thereby controlling the rate of the chemical reaction. Finally, the rate obtained from the experiment can be recorded (existing known technology). During the experiment, since the inside of the reaction container 1 is in a sealed state, if the pressure gas inside the reaction container 1 is too high during this process, When the pressure is high, the air pressure will push up the movable plug 42 through the pressure relief pipe 4. At this time, the movable plug 42 will move up through the positioning seat 41 to squeeze the buffer spring 44 and deform. When the movable plug 42 moves upward and leaks out of the through hole 43, the gas inside the reaction vessel 1 will flow into the sealing cover 5 through the pressure relief pipe 4 and the through hole 43. Then the gas will be input into the gas storage tank 61 through the gas supply pipe 611 for storage. The setting of the one-way valve 612 prevents the gas flowing into the gas supply pipe 611 from flowing back. When more pressurized gas is introduced into the gas storage assembly 6, the gas can push up the top cover 62. At this time, the top cover 62 will stretch the bellows 63 to expand the internal space of the gas storage assembly 6 to store more gas. If the collected gas is non-toxic and will not pollute the environment, the sealing valve 623 can be opened to allow the gas to be discharged through the exhaust pipe 622.

Therefore, any simple modification or equivalent replacement based on the technical solution of the utility model shall fall within the scope of protection claimed by the utility model.
