Description

Technical Field

[0001] This application relates to the field of chemical reactor sampling technology, and in particular to a chemical reactor sampling and testing device. Background Technology

[0002] In chemical production, the reactor is the core equipment for material mixing, reaction, and synthesis. The composition, concentration gradient, and physical properties of the materials inside directly determine the progress of the reaction and the quality compliance of the final product. It is the core basis for production personnel to adjust process parameters and avoid production risks. Sampling and testing is the only way to directly obtain the above key parameters. Its accuracy, timeliness, and safety are directly related to the efficiency and stability of chemical production.

[0003] Traditional sampling methods often use sampling tubes, which can only obtain material from a single depth in the reactor and cannot reflect the stratification of the material inside the reactor. This results in the detection data being seriously inconsistent with the actual reaction state. To address this issue, we propose a chemical reactor sampling and detection device. Utility Model Content

[0004] The purpose of this application is to provide a sampling and testing device for chemical reaction vessels to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A sampling and testing device for a chemical reaction vessel includes a sampling cylinder. The inner wall of the sampling cylinder is fixedly connected to partitions arranged at equal intervals. A threaded rod is rotatably connected to the inner bottom wall of the sampling cylinder. The top end of the threaded rod passes through a set of partitions and extends to the top of the sampling cylinder, with the threaded rod rotatably connected to the partitions. The outer surface of the sampling cylinder has liquid inlet grooves arranged at equal intervals. The inner wall of each liquid inlet groove is hinged with a sealing plate. The outer surface of the threaded rod is threaded with movable blocks arranged at equal intervals. The outer surface of each movable block is hinged with a push-pull plate, and the other end of each push-pull plate is hinged to the inner side of the sealing plate.

[0007] In a further embodiment, a counterweight ring is fixedly connected to the bottom end of the sampling cylinder.

[0008] In a further embodiment, a throttle is fixedly connected to the top end of the threaded rod, and an anti-slip sleeve is fitted over the outside of the throttle.

[0009] In a further embodiment, a positioning plate is fixedly connected to the outer surface of each of the moving blocks, a guide frame is slidably connected to the outer surface of each positioning plate, and one side of each guide frame is connected to the inner wall of the sampling cylinder.

[0010] In a further embodiment, the outer surface of the sampling tube is connected to drain pipes arranged at equal intervals, and each drain pipe is provided with a sealing cap inside.

[0011] In a further embodiment, a sealing pad is fixedly connected to the outer surface of each of the sealing plates, and each sealing pad is in contact with the outer surface of the sampling tube.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This application utilizes a sampling cylinder, liquid inlet tank, sealing plate, threaded rod, moving block, and push-pull plate in combination. The rotation of the threaded rod causes the moving block to move, which in turn causes the push-pull plate to deflect. The push-pull plate then opens the sealing plate, allowing the material to enter different positions inside the sampling cylinder. The sealing plate can then be closed. This method can reflect the stratification of the material inside the reactor and ensure that the test data matches the actual reaction state. Attached Figure Description

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 In this utility model, a sampling and testing device for a chemical reaction vessel includes a sampling cylinder 1. The inner wall of the sampling cylinder 1 is fixedly connected with partitions 12 arranged at equal intervals. The partitions 12 can divide the interior of the sampling cylinder 1 into multiple storage spaces. A counterweight ring 8 is fixedly connected to the bottom of the sampling cylinder 1. The counterweight ring 8 can increase the weight of the sampling cylinder 1, thereby ensuring that it enters the interior of the reaction vessel.

[0021] A threaded rod 3 is rotatably connected to the inner bottom wall of the sampling cylinder 1. The top end of the threaded rod 3 passes through a set of partitions 12 and extends to the top of the sampling cylinder 1. The threaded rod 3 is rotatably connected to the partitions 12. The outer surface of the sampling cylinder 1 has liquid inlet grooves 14 arranged at equal intervals. The inner wall of each liquid inlet groove 14 is hinged with a sealing plate 4. The outer surface of the threaded rod 3 is threaded with movable blocks 11 arranged at equal intervals. The outer surface of each movable block 11 is hinged with a push-pull plate 9. The other end of each push-pull plate 9 is hinged to the inner side of the sealing plate 4. By rotating the threaded rod 3 with the handle 2, the movable block 11 will move on the threaded rod 3. When the movable block 11 moves, it will push the push-pull plate 9. The other end of the push-pull plate 9 will push the sealing plate 4. Plate 4 and sealing plate 4 will be offset out of the liquid inlet trough 14, and liquids of different depths will enter different positions inside the sampling cylinder 1. Then, the threaded rod 3 is rotated in the opposite direction, and the push-pull plate 9 will pull the sealing plate 4 to gradually close the liquid inlet trough 14. Then the sampling cylinder 1 can be lifted out of the reaction vessel. This can reflect the stratification of materials in the vessel and ensure that the test data matches the actual reaction state. The outer surface of each moving block 11 is fixedly connected to a positioning plate 10, and the outer surface of each positioning plate 10 is slidably connected to a guide frame 13. One side of each guide frame 13 is connected to the inner wall of the sampling cylinder 1. By using the cooperation of the positioning plate 10 and the guide frame 13, the moving block 11 can be stabilized, thereby ensuring that it smoothly drives the push-pull plate 9 to move.

[0022] Each sealing plate 4 has a sealing pad 5 fixedly connected to its outer surface. Each sealing pad 5 is in contact with the outer surface of the sampling cylinder 1. The sealing pad 6 can seal the gap between the sealing plate 4 and the liquid inlet tank 14 to prevent leakage.

[0023] The top of the threaded rod 3 is fixedly connected to a handle 2, and the handle 2 is covered with an anti-slip sleeve. The handle 2 makes it convenient for workers to rotate the threaded rod 3, making the operation more convenient.

[0024] The outer surface of the sampling cylinder 1 is connected to drain pipes 6 arranged at equal intervals. Each drain pipe 6 is equipped with a sealing cap 7. The sampled material can be discharged through the drain pipe 6, while the sealing cap 7 seals the drain pipe 6 to prevent it from automatically discharging.

[0025] The working principle of this application is as follows: When in use, the sampling tube 1 is inserted into the reactor until it reaches a suitable depth. Then, the screw rod 3 is rotated by the handle 2, and the moving block 11 moves on the screw rod 3. When the moving block 11 moves, it pushes the push-pull plate 9. The other end of the push-pull plate 9 pushes the sealing plate 4, and the sealing plate 4 is offset out of the liquid inlet trough 14. Liquids at different depths will enter different positions inside the sampling tube 1. Then, the screw rod 3 is rotated in the opposite direction, and the push-pull plate 9 pulls the sealing plate 4 to gradually close the liquid inlet trough 14. Then, the sampling tube 1 can be removed from the reactor. This can reflect the stratification of materials inside the reactor and ensure that the detection data is consistent with the actual reaction state.

[0026] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
