Description

Technical Field

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

[0002] As a reaction vessel for materials, the reactor has the function of constant temperature heating to ensure that various solutes and solvents inside the reactor are at a suitable reaction temperature. Currently, reactors are equipped with a jacket, and the heating medium in the jacket is used to heat the various solutes and solvents in the reactor in a water bath. During use, after various solutes and solvents are added to the reactor, the internal stirring mechanism drives the different solutions to contact the inner wall of the reactor to achieve heating of the various solutes and solvents. However, since the temperature of the heating medium in the jacket is set to the suitable reaction temperature of the solution, it takes a long time to heat the solution to the same temperature as the heating medium in the jacket, resulting in low processing efficiency of the reactor. Utility Model Content

[0003] This invention provides a chemical safety reactor that effectively improves the efficiency of heating materials, thereby increasing the processing efficiency of the reactor.

[0004] This utility model provides the following technical solution: a chemical safety reactor, including a reactor body, a reactor top cover and a stirrer. A water bath heating jacket is fixedly connected to the outer wall of the reactor body. Four solute feed pipes are installed inside the water bath heating jacket. A control valve is installed on each solute feed pipe. Four evenly distributed solute preheating branch pipes are fixedly connected to the top of each solute feed pipe. Four solvent overheating heating rods are provided inside the reactor body. A solvent interception sleeve with a lower opening is fixedly connected to the outer wall of each solvent overheating heating rod. A solvent feed pipe is fixedly connected to the side wall of the solvent interception sleeve with a lower opening.

[0005] One end of the solute feed pipe extends into the reactor body, and the top ends of the four solute preheating branch pipes in the same group are fixedly connected to solute addition pipes.

[0006] The solute addition tube is fixedly connected to a solute supply pipe on one side, and one end of the solute supply pipe passes through the side wall of the water bath heating jacket.

[0007] The solvent intercepting sleeve with the lower opening is fixedly connected to a solvent guiding sleeve at its bottom end, and the diameter of the bottom end of the solvent guiding sleeve is smaller than the diameter of the solvent intercepting sleeve with the lower opening.

[0008] The top ends of the four solvent feed pipes are fixedly connected to a connecting pipe, which is fixedly connected to the inner wall of the reactor top cover.

[0009] The connecting pipe is fixedly connected to the side wall of the solvent supply pipe, which passes through the side wall of the reactor top cover.

[0010] The reactor body is equipped with a temperature detector, and a distance is maintained between the temperature detector and the inner wall of the reactor body and the solvent overheating heating rod.

[0011] The beneficial effects of this invention are as follows: By utilizing the medium inside the water bath heating jacket to preheat the solute before it is injected into the reactor body through the solute feed pipe and solute preheating branch pipe, and in conjunction with the solvent overheating heating rod, the solvent is rapidly heated to a temperature exceeding the appropriate reaction temperature before mixing with the solute. This effectively improves the efficiency of the reactor in heating materials, thereby increasing the reactor's processing efficiency. Furthermore, it avoids the formation of byproducts due to the solvent overheating heating rod exceeding the appropriate reaction temperature, which would otherwise affect the reaction results of the solute. The combination of the lower-opening solvent interception jacket, solvent feed pipe, and solvent guide jacket allows for full utilization of the heat from the solvent overheating heating rod when the solvent level in the reactor body is low.

[0018] Please see Figures 1-4The present invention provides the following technical solution: a chemical safety reactor, comprising a reactor body 1, a reactor top cover 11 and a stirrer 12, a water bath heating jacket 2 fixedly connected to the outer wall of the reactor body 1, four solute feed pipes 3 installed inside the water bath heating jacket 2, a control valve 31 installed on the solute feed pipes 3, four evenly distributed solute preheating branch pipes 32 fixedly connected to the top of the solute feed pipes 3, four solvent overheating heating rods 4 provided inside the reactor body 1, a lower opening solvent interception sleeve 41 fixedly connected to the outer wall of the solvent overheating heating rods 4, and a solvent feed pipe 42 fixedly connected to the side wall of the lower opening solvent interception sleeve 41.

[0019] In this implementation scheme: During the material addition stage inside the reactor body 1, the heating mechanism on the inner wall of the water bath heating jacket 2 heats the medium inside the water bath heating jacket 2 to a suitable constant temperature. During this process, the constant temperature medium preheats the solute in the solute feed pipe 3 and the solute preheating branch pipe 32. The control valve 31 is in a closed state to prevent the solute from directly entering the reactor body 1. Solvent feed pipe 42 simultaneously injects solvent into the downward-opening solvent interception sleeve 41. The solvent overheating heating rod 4 heats the solvent to a temperature exceeding that of the solute inside the water bath heating jacket 2. The high temperature exceeding the suitable reaction temperature is used to rapidly heat the solvent inside the reactor body 1. This, combined with the simultaneous heating of the solvent inside the reactor body 1 by the constant temperature water bath medium inside the water bath heating jacket 2, significantly improves the heating efficiency of the solvent until the solvent inside the reactor body 1 is heated to a temperature close to that of the constant temperature water bath medium inside the water bath heating jacket 2. During this process, the solvent is discharged from the solvent feed pipe 42 into the downward-opening solvent interception sleeve 41, and guided by the downward-opening solvent interception sleeve 41 and the solvent feed pipe 42, flows along the solvent overheating heating rod 4... The solvent flows downwards, absorbing the temperature of the solvent superheating heating rod 4 located at a higher position. This allows for full utilization of the heat from the high-level solvent superheating heating rod 4 when the solvent level in the reactor body 1 is low. Subsequently, the solvent superheating heating rod 4 stops heating the solvent in the reactor body 1. Then, the control valve 31 opens under the action of the controller, and the preheated solute in the solute feed pipe 3 and solute preheating branch pipe 32 is injected into the reactor body 1 to mix with the solvent in the reactor body 1 and react at a suitable temperature. The device can effectively improve the efficiency of heating materials in the reactor, thereby improving the reaction efficiency of the materials in the reactor. Different solutes are added to different solute feed pipes 3, and the solute supply pipe 34 is connected to different solute supply devices so that the preheated solute can be pushed into the reactor body 1 when the control valve 31 is opened. The stirrer 12 keeps rotating during operation to mix the materials in the reactor body 1, improving the heating and reaction efficiency of the materials in the reactor body 1.

[0020] One end of the solute feed pipe 3 extends into the reactor body 1, and the top ends of the four solute preheating branch pipes 32 in the same group are fixedly connected to the solute addition pipe 33; by setting the solute addition pipe 33, multiple solute preheating branch pipes 32 can be connected to inject solute into multiple solute preheating branch pipes 32.

[0021] A solute supply pipe 34 is fixedly connected to one side of the solute addition pipe 33, and one end of the solute supply pipe 34 passes through the side wall of the water bath heating jacket 2; the solute supply pipe 34 can be connected to an external solute supply device.

[0022] A solvent guide sleeve 43 is fixedly connected to the bottom end of the lower opening solvent interception sleeve 41. The diameter of the bottom end of the solvent guide sleeve 43 is smaller than the diameter of the lower opening solvent interception sleeve 41. By setting the solvent guide sleeve 43, the solvent can be gathered towards the solvent overheating heating rod 4 so that the solvent can flow downward along the solvent overheating heating rod 4.

[0023] Four solvent feed pipes 42 are fixedly connected to a connecting pipe 44 at their top ends. The connecting pipe 44 is fixedly connected to the inner wall of the reactor top cover 11. Multiple solvent feed pipes 42 can be connected by the connecting pipe 44.

[0024] A solvent supply pipe 45 is fixedly connected to the side wall of the connecting pipe 44. The solvent supply pipe 45 passes through the side wall of the reactor top cover 11. The solvent supply pipe 45 extends out of the reactor top cover 11, which can facilitate connection with an external solvent supply device.

[0025] A temperature detector 5 is installed inside the reactor body 1. There is a distance between the temperature detector 5 and the inner wall of the reactor body 1 and the solvent overheating heating rod 4. By setting the temperature detector 5, the temperature of the material inside the reactor body 1 can be detected. The temperature detector 5 is connected to the controller of the reactor body 1 and transmits signals to the controller of the reactor body 1 to control the heating of each part and the opening and closing of the pipeline.

[0026] The working principle and usage process of this utility model are as follows: During the material addition stage, the heating mechanism on the inner wall of the water bath heating jacket 2 heats the medium inside the water bath heating jacket 2 to a suitable constant temperature. During this process, the constant temperature medium preheats the solute in the solute feed pipe 3 and the solute preheating branch pipe 32. The control valve 31 is in a closed state to prevent the solute from directly entering the reactor body 1. The solvent feed pipe 42 simultaneously opens downwards and injects solvent into the solvent interception sleeve 41. The solvent overheating heating rod 4 heats the solvent to a temperature exceeding that of the solute inside the water bath heating jacket 2. The high temperature exceeding the suitable reaction temperature is used to rapidly heat the solvent inside the reactor body 1. Combined with the constant temperature water bath medium inside the water bath heating jacket 2, the solvent inside the reactor body 1 is heated simultaneously, greatly improving the heating efficiency of the solvent until the solvent inside the reactor body 1 is heated to a temperature close to... The temperature of the constant temperature water bath medium inside the water bath heating jacket 2 is controlled. During this process, the solvent is discharged from the solvent feed pipe 42 into the lower opening solvent interception sleeve 41, and flows downward along the solvent superheating heating rod 4 under the guidance of the lower opening solvent interception sleeve 41 and the solvent feed pipe 42. The solvent flowing on the surface of the solvent superheating heating rod 4 absorbs the temperature of the solvent superheating heating rod 4 located at a high position. When the solvent level in the reactor body 1 is low, the heat of the solvent superheating heating rod 4 located at a high position can be fully utilized. Subsequently, the solvent superheating heating rod 4 stops heating the solvent in the reactor body 1. Then, the control valve 31 is opened under the action of the controller. The solute that has been preheated in the solute feed pipe 3 and the solute preheating branch pipe 32 is injected into the reactor body 1 and mixed with the solvent in the reactor body 1, and the reaction is carried out at a suitable temperature.
