Description

Technical Field

[0001] This utility model relates to the field of reaction equipment technology, and in particular to a sealed reaction device for organic matter. Background Technology

[0002] Organic reaction processes refer to the industrial production processes that utilize the principles of organic chemical reactions, design reasonable reaction pathways, select suitable catalysts, and control reaction conditions to achieve the synthesis, transformation, or degradation of organic compounds.

[0003] Reactors used for organic reactions come in various types, classified by operation mode as batch (such as reaction vessels, which are flexible and suitable for small batches) and continuous (such as tubular reactors and fixed-bed reactors, which are suitable for large-scale production). In chemical production, especially in organic reactions, reactor temperature control is crucial for reaction efficiency and product purity. Therefore, reactors are usually equipped with a shell to precisely control the internal reaction temperature by introducing a heat exchange medium. To monitor the reaction process, the reactor needs to be equipped with a sampling tube to extract the reaction medium for analysis. However, due to the presence of the shell, the sampling tube must penetrate the shell area, inevitably resulting in a certain length. After the sampling operation is completed, some reaction medium will remain in the sampling tube. This residual medium cannot participate in subsequent reactions, which not only wastes raw materials but, more importantly, may undergo secondary reactions due to temperature changes in the sampling tube, generating impurities. Utility Model Content

[0004] The purpose of this invention is to provide a sealed reaction device for organic matter, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] An organic sealed reaction device includes a support frame, a reaction vessel mounted on the front side of the support frame, an outer sheath fixedly connected to the outside of the reaction vessel, and the outer sheath fixedly connected to the front side of the support frame. Two ports on the outer side of the outer sheath are respectively connected to an external temperature control and circulation device via pipes. A motor is fixedly connected to the top of the reaction vessel, and the output end of the motor extends into the reaction vessel and is fixedly connected to a stirring blade. The motor is electrically connected to an external main controller via a cable. A discharge valve is fixedly connected to the center of the bottom of the reaction vessel. A connection is also provided between the reaction vessel and the outer sheath. The sampling mechanism includes a sampling tube, one end of which is fixedly connected between the reaction vessel and the outer sheath, and the channel inside the sampling tube communicates with the inner cavity of the reaction vessel. A venting pipe is fixedly connected to the bottom of the sampling tube, and a gas pipe is fixedly connected to the top of the sampling tube. A sampling valve is fixedly connected to one end of the sampling tube, and a venting valve is fixedly connected to the bottom of the venting pipe. Multiple fixing brackets are fixedly connected inside the sampling tube, and a fixing block is fixedly connected inside the sampling tube near one of the fixing brackets. A sealing block is movably connected inside the fixing block.

[0007] As a further preferred embodiment of this utility model, the top of the sampling tube is fixedly connected with multiple internal threaded holes, and the internal thread of the internal threaded holes is connected with a fixing screw. After the fixing screw is connected to the internal thread of the internal threaded holes at the top of the sampling tube, the fixing frame and fixing block inserted in the sampling tube can be limited and fixed, thereby facilitating the assembly and maintenance of the fixing frame and fixing block.

[0008] As a further preferred embodiment of this utility model, an arc-shaped pressure block is fixedly connected to the valve ball inside the sampling valve. The arc-shaped pressure block inside the valve ball can cooperate with the push rod to realize the opening and closing operation of the sealing block, thereby realizing the discharge of the medium in the reaction vessel through the sampling tube, the fixed block, and the sampling valve.

[0009] As a further preferred embodiment of this utility model, one end of the gas tube is connected to an external gas pump through a pipeline. After sampling is completed through the sampling tube and sampling valve, the inner cavity of the sampling tube can be closed by setting the valve ball and sealing block, and the vent valve can be opened to inject inert gas to prevent residual medium in the sampling tube. In addition, a fixing block is set at one end of the sampling tube, and the sealing block is close to the reaction vessel, thereby reducing the amount of residual medium in the sampling tube.

[0010] As a further preferred embodiment of this utility model, the top of the fixing frame is provided with a first slot, and multiple connecting rods are fixedly connected between the two fixing frames. Multiple connecting rods are also fixedly connected between one of the fixing frames and the fixing block, and one end of one of the fixing screws is inserted into the first slot. The multiple fixing frames can realize the guiding movement of the push rod in the sampling tube.

[0011] As a further preferred embodiment of this utility model, a second slot is provided on the top of the fixing block, and one end of one of the fixing screws is inserted into the second slot. An inlet hole is provided in the center of the fixing block, and a side cover is fixedly connected to one side of the fixing block. Multiple through slots are provided in the side cover.

[0012] As a further preferred embodiment of this utility model, a guide shaft is fixedly connected to the center of one side of the sealing block, and a push rod is fixedly connected to the side of the sealing block opposite to the guide shaft. One side of the push rod extends through the side cover to one side of the side cover and is fitted with a retaining spring. A compression spring is also fitted on the outside of the guide shaft. The side of the push rod away from the sealing block extends through two fixing brackets to one side of the arc-shaped pressure block. When the valve ball is opened, the sealing block is pushed by the force of the compression spring, so that the sealing block drives the other end of the push rod to be inserted into the valve ball, thereby discharging the medium in the reaction tank. When the valve ball is closed, the push rod can be squeezed to one side by the arc-shaped pressure block inside the valve ball, thereby driving the sealing block to be inserted into the liquid inlet hole to close the liquid inlet hole.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, after sampling is completed, the sealing block seals the liquid inlet hole, and inert gas is introduced through the vent valve and gas pipe to discharge the residual medium, which can avoid waste of raw materials. At the same time, it reduces the generation of impurities from secondary reactions of the residual medium, ensuring the accuracy of the next sampling analysis and facilitating precise control of the reaction. The fixing frame and fixing block are fixed inside the sampling tube with screws, which facilitates assembly and maintenance and can improve the overall reliability and practicality of the device.

A sampling mechanism 6 is provided, which includes a sampling tube 7. One end of the sampling tube 7 is fixedly connected between the reaction vessel 2 and the outer sheath 3, and the inner channel of the sampling tube 7 is connected to the inner cavity of the reaction vessel 2. A drain pipe 8 is fixedly connected to the bottom of the sampling tube 7, and a gas pipe 9 is fixedly connected to the top of the sampling tube 7. A sampling valve 10 is fixedly connected to one end of the sampling tube 7, and a drain valve 11 is fixedly connected to the bottom of the drain pipe 8. Multiple fixing brackets 12 are fixedly connected inside the sampling tube 7. A fixing block 13 is fixedly connected inside the sampling tube 7 near one of the fixing brackets 12, and a sealing block 14 is movably connected inside the fixing block 13.

[0023] like Figures 3-5As shown, multiple internally threaded seat 17s are fixedly connected to the top of the sampling tube 7. The internally threaded seat 17s are connected to fixing screws 18. After connecting the fixing screws 18 to the internally threaded seat 17s at the top of the sampling tube 7, the fixing bracket 12 and fixing block 13 inserted inside the sampling tube 7 can be limited and fixed, thus facilitating the assembly and maintenance of the fixing bracket 12 and fixing block 13. An arc-shaped pressure block 16 is fixedly connected to the valve ball 15 inside the sampling valve 10. The arc-shaped pressure block 16 inside the valve ball 15 can cooperate with the push rod 26 to realize the opening and closing operation of the sealing block 14, thereby enabling the medium in the reaction vessel 2 to pass through the sampling tube 7, fixing block 13, and sampling valve 10. The exhaust pipe 9 is connected to an external air pump at one end via a pipe. After sampling is completed through the sampling pipe 7 and sampling valve 10, the inner cavity of the sampling pipe 7 can be closed by setting the valve ball 15 and sealing block 14, and the exhaust valve 11 can be opened to inject inert gas to prevent residual media in the sampling pipe 7. The sampling pipe 7 is also equipped with a fixing block 13 at one end and the sealing block 14 at one end is close to the reaction vessel 2, thereby reducing the amount of residual media in the sampling pipe 7. The top of the fixing frame 12 is provided with a first slot 20, and multiple connecting rods 19 are fixedly connected between the two fixing frames 12. Multiple connecting rods are also fixedly connected between one of the fixing frames 12 and the fixing block 13. 19, and one end of one of the fixing screws 18 is inserted into the first slot 20. Multiple fixing brackets 12 can guide the push rod 26 within the sampling tube 7. The top of the fixing block 13 has a second slot 21, and one end of one of the fixing screws 18 is inserted into the second slot 21. A liquid inlet hole 23 is provided at the center of the fixing block 13. A side cover 22 is fixedly connected to one side of the fixing block 13. Multiple through slots are provided inside the side cover 22. A guide shaft 24 is fixedly connected to the center of one side of the sealing block 14. A push rod 26 is fixedly connected to the side of the sealing block 14 opposite to the guide shaft 24. One side of the push rod 26 extends through the side cover 22. A retaining ring is attached to one side of the side cover 22, and a compression spring 25 is fitted on the outside of the guide shaft 24. The push rod 26 extends from the side away from the sealing block 14 through the two fixing brackets 12 to the side of the arc-shaped pressure block 16. When the valve ball 15 is opened, the sealing block 14 is pushed by the force of the compression spring 25, so that the sealing block 14 drives the other end of the push rod 26 to be inserted into the valve ball 15, which can discharge the medium in the reaction tank 2. When the valve ball 15 is closed, the push rod 26 can be squeezed to one side by the arc-shaped pressure block 16 inside the valve ball 15, so that the push rod 26 drives the sealing block 14 to be inserted into the liquid inlet 23 to close the liquid inlet 23.

[0024] It should be noted that this utility model is an organic sealed reaction device. In use, the external temperature control circulation device is connected to the outer sheath 3 through a pipe to regulate the temperature inside the reaction tank 2. Motor 4 starts, driving the stirring blades to rotate, allowing the materials in reaction tank 2 to react fully. During sampling, sampling valve 10 is opened, valve ball 15 rotates, and the position of the through hole in valve ball 15 gradually rotates to the side of push rod 26, thereby opening sampling valve 10. At this time, compression spring 25 pushes sealing block 14 to move, opening liquid inlet hole 23 of fixed block 13. The reaction medium flows through sampling pipe 7 to sampling valve 10 to complete sampling. After sampling, sampling valve 10 is manually closed, valve ball 15 is reset, arc-shaped pressure block 16 squeezes push rod 26, and when arc-shaped pressure block 16 gradually squeezes and pushes push rod 26, it abuts against the outside of valve ball 15. Thus, push rod 26 drives sealing block 14 to close liquid inlet hole 23. Subsequently, vent valve 11 is opened, and external air pump introduces inert gas into sampling pipe 7 through air pipe 9, discharging residual medium through vent pipe 8.
