Technical Field
[0001] This application relates to the field of sampling technology, and particularly to a sealed sampling device and a reaction kettle. Background Art
[0002] Reaction kettles are widely used in industries such as petroleum, chemical engineering, rubber, pesticides, dyes, pharmaceuticals, food, etc., and in scientific research experiments. Their main function is to complete the whole process from feeding, reacting to discharging. The design of these reaction kettles usually requires careful optimization of their structural functions and configured accessories according to reaction conditions to achieve an efficient reaction process. During operation, these devices usually need to strictly control important parameters such as temperature, pressure, mechanical control, and the concentrations of reactants and products to ensure that the reaction proceeds as required.
[0003] However, in actual operation, monitoring the reaction situation of the materials in the reaction kettle often relies on setting a sampling pipe on the reaction kettle for sampling. The current sampling method is usually carried out during the reaction process from the valve at the bottom of the reaction kettle or the feeding port at the top of the kettle. This operation method has many challenges. Chemical reactions usually occur under high-temperature and high-pressure conditions, which makes the sampling operation extremely complex and has potential safety risks. In a closed or high-pressure environment, the sampling operation is particularly difficult, and the sampling position is single, which easily leads to a reduction in sampling accuracy. In addition, the existing sealing system may cause sample contamination or gas leakage in the reaction system during the sampling process. These problems not only affect the representativeness and reliability of sampling, but may also have a negative impact on the reaction process and experimental results.
[0004] Therefore, there is an urgent need to develop a new sampling system that can efficiently and pollution-free sample in a closed environment. Summary of the Utility Model
[0005] In order to be able to efficiently and pollution-free sample in a closed environment, this application provides a sealed sampling device and a reaction kettle.
[0006] The sealed sampling device and reaction kettle provided by this application adopt the following technical solutions:
[0007] A sealed sampling device for sampling a device to be sampled. The sealed sampling device includes a bracket, a sampler and a lifting assembly arranged on the bracket. The sampler is located inside the device to be sampled, and the lifting assembly is connected to the sampler and drives the sampler to move for sampling; the device to be sampled is provided with a sampling hole, and the sample liquid in the sampler is taken out through the sampling hole. The sampler and the device to be sampled are in abutting seal through a concave-convex structure, and the concave-convex structure forms a seal around the sampling hole.
[0008] By adopting the above technical solution, during operation, the lifting assembly drives the sampler to move up and down in the device to be sampled for sampling, inhaling or collecting the sample into the sampler. After sampling, the lifting assembly drives the sampler to continue moving until the sampler abuts against the device to be sampled. At this time, the concave-convex structure ensures a seal is formed between the sampler and the device to be sampled, and the concave-convex structure also seals the periphery of the sampling hole. Then, the operator can take out the sample liquid in the sampler through the sampling hole. The seal of the sampling hole ensures that the sample is not contaminated or leaked during the extraction process. In the above process, the lifting assembly makes the movement control of the sampler more precise, improving the sampling efficiency. The concave-convex structure design ensures good sealing effect during sampling, avoiding sample leakage or contamination and improving the sampling accuracy. The seal design reduces the risk of sample leakage, protecting the operator and the environment. It can perform sampling under various environmental conditions, including harsh conditions such as high temperature and high pressure. Moreover, the automated sampler and lifting assembly make the operation more convenient, reducing the complexity of manual operation.
[0009] In a specific feasible implementation, the lifting assembly includes a first motor, the motor shaft of the first motor is connected to a first lead screw, a first slider is rotatably connected to the first lead screw, and the first slider is connected to the sampler through a magnetic attraction assembly.
[0010] By adopting the above technical solution, during operation, the first motor starts running. The rotation of the motor directly drives the first lead screw to rotate. The rotation of the first lead screw makes the first slider move along the thread direction of the first lead screw, thereby driving the sampler to move up and down to reach the required sampling position. The lifting assembly drives the first lead screw to rotate through the motor, making the first slider move linearly, and then realizing the lifting of the sampler through the connecting rod. Its design ensures precise control, stability and efficient movement, while simplifying the operation and improving the durability of the system.
[0011] In a specific feasible implementation, the magnetic attraction assembly includes a sliding tube and a connecting rod connected to the first slider. The sliding tube is fixed inside the device to be sampled. The sampler passes through the sliding tube and slides on the sliding tube. The connecting rod is inserted into the sliding tube and moves inside the sliding tube. The sampler is magnetically connected to the connecting rod through a magnet.
[0012] By adopting the above technical solution, using the magnet to magnetically connect the sampler and the connecting rod can achieve the effect of driving the sampler to move up and down along the sliding tube by the connecting rod, and can ensure that the sampler will not loosen or fall off during the movement process, improving the stability of the system, realizing a stable and efficient sampling process, and at the same time improving the durability and operation consistency of the system.
[0013] In a specific feasible implementation, a valve is further included. The sampler is provided with a sampling flow channel, and the sampling flow channel is communicated with the sampling hole. The valve is arranged on the sampler and communicated with the sampling flow channel to control the size of the liquid flow rate entering the sampling flow channel and the sampling volume.
[0014] By adopting the above technical solution, the combination of the valve and the sampling flow channel allows for more meticulous management of the sampling process, improves the accuracy and stability of flow control. Through the adjustment function of the valve, it can adapt to the requirements of different sampling volumes, improve the flexibility and convenience of sampling, and also optimize the resource utilization efficiency.
[0015] In a specific feasible implementation, the concave-convex structure includes a first arc surface arranged on the sampler and a second arc surface arranged on the device to be sampled. The sampling hole extends to the second arc surface, the sampling flow channel extends to the first arc surface, and the first arc surface and the second arc surface are arranged in a fitting manner.
[0016] By adopting the above technical solution, the fitting of the first arc surface and the second arc surface forms an effective sealing contact surface, ensuring the sealing performance around the sampling hole and the sampling flow channel, reducing the possibility of liquid leakage, and ensuring the integrity of the sealing inside the device to be sampled when the sample liquid is taken out from the flow channel of the sampler through the sampling hole.
[0017] In a specific feasible implementation, a cleaning component and a driving component are further included. The driving component is used to drive the cleaning component to insert into the sampling hole to wash the sampling hole.
[0018] By adopting the above technical solution, during the cleaning operation, the driving component is started to control the cleaning component to insert into the sampling hole. The cleaning component unfolds its cleaning function in the sampling hole to comprehensively wash the inside of the sampling hole, removing residues and impurities. After the washing is completed, the driving component withdraws the cleaning component to its original position to ensure that the sampling hole is in a clean state and prepares for subsequent sampling. Through the combined design of the cleaning component and the driving component, the overall performance and stability of the sampling system are improved. The automatic control operation of the driving component makes the cleaning process more efficient and convenient, reduces manual intervention, and improves the convenience of system operation.
[0019] In a specific feasible implementation, the driving component includes a second motor arranged on the bracket. The motor shaft of the second motor is connected with a second lead screw. The second lead screw is rotationally connected with a second slider, and the cleaning component is connected with the second slider.
[0020] By adopting the above technical solution, during the cleaning operation, the second motor starts, driving the second lead screw to rotate. The rotation is converted into the linear motion of the second slider, thereby driving the cleaning assembly to move and insert into the sampling hole. The cleaning assembly unfolds its cleaning function within the sampling hole. Through the linkage of the second motor, the second lead screw, and the second slider, the insertion and retraction positions of the cleaning assembly can be accurately controlled, realizing an efficient and automated cleaning process, ensuring the cleanliness of the sampling hole and the long-term stability of the equipment.
[0021] In a specific feasible embodiment, the cleaning assembly includes a cleaning head. The cleaning head inserts into the sampling hole, and the cleaning head is connected to the second slider through a spring structure. The spring structure is used to prevent the cleaning head from damaging the device to be sampled during the insertion process.
[0022] By adopting the above technical solution, during the cleaning operation, the cleaning head enters the sampling hole through the linear motion of the second slider. During the insertion process of the cleaning head, the spring structure plays a buffering role, preventing the cleaning head from causing physical damage to the inner wall of the sampling hole and the device to be sampled, effectively protecting the sampling device and the cleaning head, and reducing the risk of mechanical damage. And the buffering effect of the spring makes the cleaning process smoother, improving the reliability of the cleaning operation.
[0023] In a specific feasible embodiment, the cleaning assembly further includes a valve body and a third motor. The motor shaft of the third motor is connected to the valve body, and the third motor is used to drive the valve body to move to control the opening and closing of the cleaning liquid in the cleaning head.
[0024] By adopting the above technical solution, during operation, the third motor is connected to the valve body through the motor shaft and is responsible for driving the movement of the valve body. The rotation of the motor opens or closes the valve body, thereby controlling the flow of the cleaning liquid. The valve body can control the flow of the cleaning liquid, determine whether the cleaning liquid can flow into the cleaning head, and switch between the open and closed states, thereby adjusting the supply of the cleaning liquid.
[0025] A reactor includes the sealed sampling device as described above. The bracket and the lifting assembly are arranged outside the reactor, and the sampler is arranged inside the reactor.
[0026] In a specific feasible embodiment, the reactor includes a kettle body and a cover plate. The cover plate is connected to the kettle body and seals the opening of the kettle body. The bracket and the lifting assembly are arranged on the cover plate, and the cover plate and the kettle body are sealed through a sealing ring.
[0027] By adopting the above technical solution, the cover plate and the kettle body are sealed through a sealing ring. The sealing ring can effectively prevent the leakage of reactants and gases, ensuring that the reactor maintains a good sealing state during operation, thereby improving the safety and accuracy of the reaction process.

[0036] The following will further elaborate on the present application in conjunction with the attached Figures 1-4 drawings for a more detailed description.
[0037] Referring to Figure 1 and Figure 2 In this embodiment of the present application, a sealed sampling device is disclosed for sampling a device to be sampled. In this embodiment, the device to be sampled is a reaction kettle. The reaction kettle 1 includes a kettle body 12 and a cover plate 11. The cover plate 11 is connected to the kettle body 12 and seals the opening of the kettle body 12. A sealing ring 9 is provided between the cover plate 11 and the kettle body 12 for sealing. The sealing ring 9 can effectively prevent the leakage of reactants and gases, ensuring that the reaction kettle 1 maintains a good sealing state during operation, thereby improving the safety and accuracy of the reaction process.
[0038] The sealed sampling device 2 includes a bracket 3, a sampler 4 provided on the bracket 3, and a lifting assembly 5. The bracket 3 is provided on the outer wall of the cover plate 11 of the reaction kettle 1 and the bracket 3 is vertically arranged. In this embodiment, the bracket 3 includes but is not limited to being fixed to the cover plate 11 by bolts. The lifting assembly 5 is provided on the bracket 3. The sampler 4 is located inside the kettle body 12 of the reaction kettle 1. The lifting assembly 5 is connected to the sampler 4 and drives the sampler 4 to move up and down vertically for sampling. The device to be sampled is provided with a sampling hole 13. The sampler 4 and the device to be sampled are in abutting seal through a concave-convex structure 6. In this embodiment, the sampling hole 13 is provided on the cover plate 11 of the reaction kettle 1. The sampler 4 and the cover plate 11 of the reaction kettle 1 are in abutting seal through a concave-convex structure 6. When the sampler 4 abuts against the cover plate 11, the sampling hole 13 is communicated with the sampler 4. The concave-convex structure 6 forms a seal around the sampling hole 13, and the sample liquid in the sampler 4 is taken out through the sampling hole 13.
[0039] During operation, the lifting assembly 5 drives the sampler 4 to move up and down in the reaction kettle 1 for sampling, sucking or collecting the sample into the sampler 4. After sampling, the lifting assembly 5 drives the sampler 4 to continue to move until the sampler 4 abuts against the cover plate 11 of the reaction kettle 1. At this time, the concave-convex structure 6 ensures the formation of a seal between the sampler 4 and the cover plate 11 of the reaction kettle 1, and the concave-convex structure 6 will form a seal around the sampling hole 13. The operator can then take out the sample liquid in the sampler 4 through the sampling hole 13. The seal of the sampling hole 13 ensures that the sample is not contaminated or leaked during the extraction process.
[0040] During this process, the lifting assembly 5 makes the movement control of the sampler 4 more precise, improving the sampling efficiency. The design of the concave-convex structure 6 ensures good sealing effect during sampling, avoiding sample leakage or contamination, improving the sampling accuracy. The sealing design reduces the risk of sample leakage, protects the operator and the environment, and can perform sampling under various environmental conditions, including harsh conditions such as high temperature and high pressure. Moreover, the automated sampler 4 and the lifting assembly 5 make the operation more convenient, reducing the complexity of manual operation.
[0041] Referring to Figure 2 and Figure 3, the lifting assembly 5 includes a first motor 51. In this embodiment, the first motor 51 is provided at the top of the bracket 3. The motor shaft of the first motor 51 is connected to a first lead screw 52. The first lead screw 52 is arranged along the height direction of the bracket 3. A first slider 53 is rotatably connected to the first lead screw 52. The first slider 53 is connected to the sampler 4 through a magnetic attraction assembly 10;
[0042] The magnetic attraction assembly 10 includes a sliding tube 55 and a connecting rod 54 connected to the first slider 53. In this embodiment, the sliding tube 55 is a glass tube and the connecting rod 54 is a metal rod. The sliding tube 55 is fixed in the reaction kettle 1. The sampler 4 passes through the sliding tube 55 and slides on the sliding tube 55. The connecting rod 54 is inserted into the sliding tube 55 and moves inside the sliding tube 55. The sampler 4 is magnetically connected to the connecting rod 54 through a magnet; by magnetically connecting the sampler 4 and the connecting rod 54 through a magnet, when the connecting rod 54 moves up and down, the sampler 4 can be driven to move up and down along the sliding tube 55 due to the magnetic attraction effect, so as to achieve the effect of driving the sampler 4 to move up and down for sampling, and it can ensure that the sampler 4 will not loosen or fall off during the movement process, improve the stability of the system, realize a stable and efficient sampling process, and at the same time improve the durability and operation consistency of the system;
[0043] During operation, the first motor 51 starts to run. The rotation of the first motor 51 directly drives the first lead screw 52 to rotate. The rotation of the first lead screw 52 makes the first slider 53 move along the thread direction of the first lead screw 52, thereby driving the connecting rod 54 to move up and down inside the sliding tube 55. When the connecting rod 54 moves up and down, the sampler 4 can be driven to move up and down along the sliding tube 55 due to the magnetic attraction effect, reaching the required sampling position; the lifting assembly 5 drives the first lead screw 52 to rotate through the motor, making the first slider 53 linearly move, and then realizing the lifting of the sampler 4 through the connecting rod 54; its design ensures precise control, stability and efficient movement, while simplifying the operation and improving the durability of the system.
[0044] Refer to Figure 2 and Figure 3 , the sealed sampling device 2 further includes a valve 42. In this embodiment, the valve 42 includes but is not limited to a six-way valve. The sampler 4 is provided with a sampling flow channel 41. The valve 42 is arranged on the sampler 4 and communicated with the sampling flow channel 41. The valve 42 is used to control the size of the liquid flow rate entering the sampling flow channel 41 and the sampling volume. In this embodiment, the sampling flow channel 41 is set to 6, which corresponds to the valve flow channels of the six-way valve one by one. In this embodiment, the 6 sampling flow channels 41 converge to form a sampling groove on the side away from the valve body 72. When the sampler 4 abuts against the cover plate 11 of the reaction kettle 1, the sampling groove is communicated with the sampling hole 13;
[0045] The sampling system introducing valve 42 precisely adjusts the sampling volume by controlling the liquid flow rate. The combination of valve 42 and sampling flow channel 41 allows for more meticulous management of the sampling process, improving the accuracy and stability of flow control. Through the adjustment function of valve 42, it can adapt to the requirements of different sampling volumes, enhancing the flexibility and convenience of sampling, and also optimizing the resource utilization efficiency.
[0046] Refer to Figure 2 and Figure 3 , the concave-convex structure 6 includes a first arc surface 61 provided on the sampler 4 and a second arc surface 62 provided on the cover plate 11 of the reaction kettle 1. In this embodiment, the first arc surface 61 includes but is not limited to a convex arc surface, and the second arc surface 62 includes but is not limited to a concave arc surface. The sampling hole 13 extends to the second arc surface 62, and the sampling flow channel 41 extends to the first arc surface 61. When the sampler 4 abuts against the cover plate 11, the first arc surface 61 and the second arc surface 62 are arranged in a fitting manner, and a seal is formed around the sampling hole 13 and the sampling flow channel 41;
[0047] By utilizing the fitting of the first arc surface 61 and the second arc surface 62, an effective sealing contact surface is formed to ensure the sealing property around the sampling hole 13 and the sampling flow channel 41, reducing the possibility of liquid leakage, and ensuring the integrity of the sealing inside the device to be sampled when the sample liquid is taken out from the flow channel of the sampler 4 through the sampling hole 13; and the sampling hole 13 extends from the device to be sampled to the second arc surface 62, and the sampling flow channel 41 extends from the first arc surface 61, ensuring that the sampling hole 13 can accurately dock with the sampling flow channel 41, so as to smoothly achieve the purpose of taking out the sample liquid in the sampler 4 through the sampling hole 13.
[0048] Refer to Figure 3 and Figure 4 , the sealed sampling device 2 further includes a cleaning component 7 and a driving component 8. The driving component 8 is used to drive the cleaning component 7 to insert into the sampling hole 13 to flush the sampling hole 13;
[0049] The driving component 8 includes a second motor 81 provided on the bracket 3. The motor shaft of the second motor 81 is connected with a second lead screw 82. The second lead screw 82 is arranged along the height direction of the bracket 3. The axis of the second lead screw 82 is parallel to the axis of the first lead screw 52. The second lead screw 82 is rotationally connected with a second slider 83. The cleaning component 7 is connected with the second slider 83; through the linkage of the second motor 81, the second lead screw 82 and the second slider 83, the insertion and retraction positions of the cleaning component 7 can be precisely controlled to achieve an efficient and automated cleaning process, ensuring the cleanliness of the sampling hole 13 and the long-term stability of the equipment;
[0050] The cleaning assembly 7 includes a cleaning head 71. The cleaning head 71 is inserted into the sampling hole 13. The cleaning head 71 is connected to the second slider 83 through a spring structure 84. In this embodiment, the spring structure 84 includes but is not limited to a pneumatic spring structure. In this embodiment, the spring structure 84 makes the downward pressure of the cleaning head 71 less than or equal to a set value, thereby preventing the cleaning head 71 from damaging the reactor 1 during the insertion process. And the spring structure 84 can also make the cleaning head 71 in close contact with the sampling hole 13 to form a relative seal, preventing the cleaning liquid in the cleaning head 71 from splashing. During the insertion of the cleaning head 71, the spring structure 84 plays a buffering role, preventing the cleaning head 71 from causing physical damage to the inner wall of the sampling hole 13 and the device to be sampled, effectively protecting the sampling device and the cleaning head 71, reducing the risk of mechanical damage. And the buffering effect of the spring makes the cleaning process more stable, improving the reliability of the cleaning operation.
[0051] The cleaning assembly 7 further includes a valve body 72 and a third motor 73 provided on the cleaning head 71. The motor shaft of the third motor 73 is connected to the valve body 72. The third motor 73 is used to drive the valve body 72 to move to control the opening and closing of the cleaning liquid in the cleaning head 71. The valve body 72 can control the flow of the cleaning liquid, determine whether the cleaning liquid can flow into the cleaning head 71, and switch between the open and closed states, thereby regulating the supply of the cleaning liquid.
[0052] During the cleaning operation, the second motor 81 is started to drive the second lead screw 82 to rotate. The rotation is converted into a linear motion of the second slider 83, thereby driving the spring structure 84 and the cleaning head 71 to move downward, so that the cleaning head 71 is inserted into the sampling hole 13. At this time, the third motor 73 is started. The third motor 73 is connected to the valve body 72 through the motor shaft and is responsible for driving the movement of the valve body 72. The rotation of the motor opens the valve body 72 to control the flow of the cleaning liquid, so that the cleaning head 71 unfolds its cleaning function in the sampling hole 13 to comprehensively wash the inside of the sampling hole 13 to remove residues and impurities.
[0053] After the flushing is completed, the second motor 81 is started to drive the second lead screw 82 to rotate, driving the second slider 83 to move linearly upward, thereby driving the entire cleaning assembly 7 to withdraw to its original position, ensuring that the sampling hole 13 is in a clean state and preparing for subsequent sampling.
[0054] The implementation principle of the embodiment of this application is as follows: During the sampling operation, the first motor 51 starts to run. The rotation of the first motor 51 directly drives the rotation of the first lead screw 52. The rotation of the first lead screw 52 causes the first slider 53 to move downward along the thread direction of the first lead screw 52, thereby driving the connecting rod 54 to move up and down within the sliding tube 55. When the connecting rod 54 moves up and down, due to the magnetic attraction effect, it can drive the sampler 4 to move up and down along the sliding tube 55 to reach the required sampling position; during sampling, according to the actual sampling volume requirement, by controlling the opening of each valve flow path of the control valve 42, the liquid flow rate into each sampling flow path 41 within the sampler 4 is controlled. When the sampling volume reaches the requirement, the control valve 42 is closed;
[0055] After the sampling is completed, the first motor 51 is started to drive the first lead screw 52 to rotate in the reverse direction, causing the first slider 53 to move upward along the thread direction of the first lead screw 52, thereby driving the sampler 4 to move upward so that the sampler 4 abuts against the cover plate 11 of the reaction kettle 1. At this time, the sampling hole 13 on the cover plate 11 of the reaction kettle 1 is communicated with the sampling flow path 41 of the sampler 4, and at the same time, the first arc surface 61 of the sampler 4 fits with the second arc surface 62 of the cover plate 11 to form an effective sealing contact surface, ensuring the sealing performance around the sampling hole 13 and the sampling flow path 41. Then, a tool can be used to take out the sample liquid in the sampler 4 through the sampling hole 13 to complete the sampling operation;
[0056] By designing the lifting component 5 in this application, the movement control of the sampler 4 is more accurate, stable and efficient, improving the sampling efficiency; through the concave-convex structure 6 design of the first arc surface 61 and the second arc surface 62, it is ensured that the sealing effect is good during the sampling process, avoiding sample leakage or contamination, improving the sampling accuracy. The sealing design reduces the risk of sample leakage, protects the operators and the environment, and can perform sampling under various environmental conditions, including harsh conditions such as high temperature and high pressure. Moreover, the automated sampler 4 and the lifting component 5 make the operation more convenient and reduce the complexity of manual operation.
