Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, specifically a chemical reaction vessel. Background Technology

[0002] A reaction vessel is a container used for carrying out chemical reactions. Its main functions include providing a chemical reaction site, controlling reaction conditions, improving reaction efficiency, and ensuring product quality. It is commonly used in the chemical industry, pharmaceutical field, and new material research and development. Different types of reaction vessels are suitable for different reaction needs, and the appropriate reaction vessel can be selected according to the specific process requirements.

[0003] According to the utility model patent application CN219291363U, a chemical reactor is disclosed. While this reactor uses a barrier mesh to ensure the catalyst rotates with the stirring plate, facilitating full contact between the catalyst and liquid raw materials, and the barrier mesh also fixes the catalyst within the stirring plate, allowing the heat medium to move downwards along the rotating rod and heat exchange plate via a rotary joint, thus achieving heating of the central area of ​​the reactor, and the heat exchange plate being located within the catalyst to ensure the temperature of the catalyst in contact with the liquid raw materials, thereby effectively improving catalytic efficiency while ensuring overall heating, the presence of this heating structure and the fact that reactions typically involve pressure increases, coupled with the lack of high-temperature and high-pressure alarms and pretreatment safety structures, poses a risk of explosion due to excessively high temperatures and pressures. Therefore, we provide a chemical reactor to address these issues. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a chemical reaction vessel.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a chemical reaction vessel, including a reaction vessel body, a sealing door movably hinged to the right side of the reaction vessel body, and a safety mechanism provided on the outside of the reaction vessel body;

[0006] The safety mechanism includes a high-pressure solenoid valve and a support frame. A warning flashing light and an alarm speaker are fixedly connected to the upper surface of the support frame. A connecting pipe is fixedly connected to the input end of the high-pressure solenoid valve and the outer surface of the reactor body. An exhaust pipe is fixedly connected to the output end of the high-pressure solenoid valve. An explosion-proof digital display pressure gauge is fixedly connected to the outer surface of the connecting pipe. A button controller is fixedly connected to the outer surface of the reactor body. A temperature sensor is fixedly connected to the inner wall of the reactor body.

[0007] Furthermore, the bottom end of the support frame is fixedly connected to the upper surface of the reactor body. The high-pressure solenoid valve, warning flashing light, alarm speaker, explosion-proof digital display pressure gauge and temperature sensor are all electrically connected to the button controller through wires. Two support plates are fixedly connected to the outer surface of the reactor body, and a mounting base plate is fixedly connected to the bottom surface of each support plate.

[0008] Furthermore, a conductive block is fixedly connected to the outer surface of the reactor body, and an electrostatic conductive chain is fixedly connected to the bottom surface of the conductive block.

[0009] Furthermore, a handle support is fixedly connected to the front of the sealed door, and a handle is rotatably connected to the inner wall of the handle support.

[0010] Furthermore, two fixing rods are fixedly connected to the outer surface of the reactor body, and two limiting rods are fixedly connected to the left side of the sealing door.

[0011] Furthermore, two limiting plates are provided on the left side of the sealing door. The inner wall of each limiting plate is rotatably connected to the outer surface of the fixing rod, and the interior of each limiting plate is engaged with the outer surface of the limiting rod.

[0012] Furthermore, both the outer surface of the input end of the high-pressure solenoid valve and the outer surface of the output end of the high-pressure solenoid valve are fixedly connected with sealing rings. The inner wall of one of the sealing rings is fixedly connected to the outer surface of the connecting pipe, and the inner wall of the other sealing ring is fixedly connected to the outer surface of the exhaust pipe.

[0013] Compared with existing technologies, this chemical reaction vessel has the following advantages:

[0014] This invention utilizes the coordinated components of a reaction vessel body, a sealed door, a button controller, a high-pressure solenoid valve, a support frame, a temperature sensor, a connecting pipe, an explosion-proof digital pressure gauge, an exhaust pipe, a warning flashing light, and an alarm speaker. The reaction vessel body can hold the chemical materials required for the chemical reaction and provide the appropriate reaction environment and regulation. The button controller monitors the temperature inside the reaction vessel as measured by the temperature sensor and the gas pressure inside the reaction vessel body and connecting pipe as measured by the explosion-proof digital pressure gauge. Operating the button controller allows setting the desired temperature and pressure ranges within the reaction vessel body. When the temperature or pressure inside the reaction vessel exceeds the monitoring range set by the button controller, the button controller will activate the warning flashing light and the alarm speaker to sound an alarm. Simultaneously, the button controller controls the high-pressure solenoid valve to connect the connecting pipe and the exhaust pipe, allowing the high-temperature or high-pressure gas inside the reaction vessel to be discharged through the connecting pipe and the exhaust pipe, thereby reducing the temperature or pressure inside the reaction vessel and preventing explosions due to excessively high temperature or pressure. This avoids the risk of explosion due to excessively high temperature and pressure caused by the lack of a high-temperature and high-pressure alarm and pretreatment safety structure.

[0020] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are only for explaining this utility model and are not intended to limit the scope of this utility model.

[0021] This embodiment provides a chemical reaction vessel. This device is used in chemical reaction scenarios in chemical production. It can monitor and warn of the temperature and pressure of the chemical reaction inside the reaction vessel body 1 and the sealing door 2. When the temperature and pressure inside the reaction vessel body 1 are high, it can depressurize and exhaust gas to cool down the reaction vessel body 1, thereby preventing the reaction vessel body 1 from exploding and increasing the safety of the reaction vessel body 1.

[0022] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 A chemical reaction vessel includes a reaction vessel body 1. A sealing door 2 is movably hinged to the right side of the reaction vessel body 1. A safety mechanism 3 is provided on the outside of the reaction vessel body 1. The safety mechanism 3 includes a high-pressure solenoid valve 302 and a support frame 303. A warning flashing light 308 and an alarm speaker 309 are fixedly connected to the upper surface of the support frame 303. The bottom end of the support frame 303 is fixedly connected to the upper surface of the reaction vessel body 1. Two support plates 4 are fixedly connected to the outer surface of the reaction vessel body 1. A mounting base plate 5 is fixedly connected to the bottom surface of each support plate 4. By providing support plates 4, the reaction vessel body 1 can be raised and stably supported. By providing mounting base plates 5, the mounting base plates 5 can be fixedly connected to the mounting docking structure with external bolts or pins, thereby increasing the stability of the entire reaction vessel during installation and placement.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The input end of the high-pressure solenoid valve 302 and the outer surface of the reactor body 1 are fixedly connected by a connecting pipe 305. A conductive block 6 is fixedly connected to the outer surface of the reactor body 1, and an electrostatic conductor 7 is fixedly connected to the bottom surface of the conductive block 6. By setting the conductive block 6, the static electricity on the reactor body 1 can be guided to the electrostatic conductor 7, and then the electrostatic conductor 7 will guide the static electricity on the reactor body 1 to the ground, thereby preventing excessive static electricity accumulation on the reactor body 1 from generating sparks and avoiding the sparks from igniting the reactor body 1.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The output end of the high-pressure solenoid valve 302 is fixedly connected to the exhaust pipe 307. The front of the sealing door 2 is fixedly connected to the handle support 8. The inner wall of the handle support 8 is rotatably connected to the handle 9. By setting the handle 9, it can rotate around the inner wall of the handle support 8, thereby increasing the flexibility of the handle 9 and making it convenient to push and pull the sealing door 2.

[0025] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4An explosion-proof digital pressure gauge 306 is fixedly connected to the outer surface of the connecting pipe 305. Two fixing rods 10 are fixedly connected to the outer surface of the reactor body 1. Two limiting rods 11 are fixedly connected to the left side of the sealing door 2. By setting the fixing rods 10, a rotation base surface can be provided for other limiting structures. By setting the limiting rods 11, the above-mentioned limiting structures can be limited.

[0026] Reference Figure 1 and Figure 4 A button controller 301 is fixedly connected to the outer surface of the reactor body 1. Two limiting plates 12 are provided on the left side of the sealing door 2. The inner wall of each limiting plate 12 is rotatably connected to the outer surface of the fixed rod 10. The interior of each limiting plate 12 is engaged with the outer surface of the limiting rod 11. By setting the limiting plates 12, the sealing door 2 can rotate around the outer surface of the fixed rod 10 and engage with the outer surface of the limiting rod 11, thereby increasing the relative closing stability of the sealing door 2 and the reactor body 1.

[0027] Reference Figure 1 , Figure 2 and Figure 3 A temperature sensor 304 is fixedly connected to the inner wall of the reactor body 1. The high-pressure solenoid valve 302, the warning flashing light 308, the alarm speaker 309, the explosion-proof digital display pressure gauge 306, and the temperature sensor 304 are all electrically connected to the button controller 301 through wires. The outer surface of the input end and the outer surface of the output end of the high-pressure solenoid valve 302 are both fixedly connected to sealing rings 13. The inner wall of one sealing ring 13 is fixedly connected to the outer surface of the connecting pipe 305, and the inner wall of the other sealing ring 13 is fixedly connected to the outer surface of the exhaust pipe 307. By setting the sealing rings 13, the connection between the high-pressure solenoid valve 302 and the connecting pipe 305, as well as the connection between the high-pressure solenoid valve 302 and the exhaust pipe 307, can be strengthened respectively, thereby increasing the sealing between each of the above two.

[0028] Working principle: In use, rotate the limit plate 12 around the fixed rod 10 and move it away from the limit rod 11. Then, hold the handle 9 and pull the sealing door 2 away from the reactor body 1. Next, put the material to be reacted into the reactor body 1 and wait for it to be stirred by the built-in stirring structure or heated by the heating structure inside the reactor body 1. After closing the sealing door 2 and the reactor body 1, rotate the limit plate 12 around the fixed rod 10 and lock it with the limit rod 11. Then, operate the button controller 301 to set the temperature range to be monitored by the temperature sensor 304 and the pressure range to be monitored by the explosion-proof digital display pressure gauge 306. When the temperature sensor 304 detects that the temperature inside the reactor body 1 exceeds the temperature range set by the button controller 301, or when the explosion-proof digital display pressure gauge 306 detects that the air pressure inside the reactor body 1 and the connecting pipe 305 exceeds the pressure range set by the button controller 301, the button controller 301 controls the warning flashing light 308 to start flashing and the alarm speaker 309 to sound. An alarm sound is emitted, and simultaneously, the button controller 301 automatically energizes the high-pressure solenoid valve 302 to connect the connecting pipe 305 and the exhaust pipe 307. High-temperature or high-pressure gas inside the reactor body 1 is discharged through the exhaust pipe 307 after passing through the connecting pipe 305 and the high-pressure solenoid valve 302. Then, due to the leakage of high-temperature or high-pressure gas, the temperature inside the reactor body 1 drops to the normal range set by the button controller 301, or the gas pressure inside the reactor body 1 drops to the normal range set by the button controller 301. The button controller 301 then controls the high-pressure solenoid valve 302 to disconnect the connecting pipe 305 and the exhaust pipe 307 again. This achieves alarm and corresponding pretreatment for high temperature and high pressure inside the reactor body 1, and minimizes the risk of explosion due to high temperature or high pressure. The design of the entire chemical reactor effectively solves the problem of the risk of explosion due to excessively high temperature and high pressure caused by the lack of a safety structure for high-temperature and high-pressure alarm and pretreatment.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
