Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessel technology, and in particular to a reaction vessel that facilitates sampling. Background Technology
[0002] To promptly ascertain the reaction status of materials within the reactor, sampling is sometimes necessary. However, sampling is inconvenient during stirring, requiring the stirring equipment to be paused, which may affect the reaction efficiency. Existing reactors, for ease of sampling, have a sampling pipe with a valve on one side of the bottom; simply opening the valve allows for sampling. However, for materials with high viscosity and poor flowability, this can easily leave significant residue in the sampling pipe, affecting subsequent sampling results. Furthermore, the sampling speed is slow and inconvenient. Utility Model Content
[0003] To address the aforementioned issues, this invention provides a convenient sampling reactor, which facilitates the sampling of materials with high viscosity and poor flowability, reduces residue, and is less likely to affect sampling results.
[0004] The technical solution of this utility model is as follows:
[0005] A convenient sampling reactor includes a reactor body and a sampling structure. The reactor body has a feed inlet at the top and a discharge outlet at the bottom, and a support foot at the bottom edge of the reactor body. The sampling structure includes a sampling tube and a sampling piston. A sampling port is opened on the side wall of the reactor body. The sampling tube is connected to the sampling port and the sampling piston at both ends, respectively. A valve is provided on the sampling tube. The sampling piston is detachably connected to the sampling tube.
[0006] In a further technical solution, the sampling piston includes a piston cylinder, a piston rod, and a piston head. One end of the piston cylinder is open and communicates with the sampling tube, and the other end is provided with an end cap. The middle of the end cap is provided with a through hole for matching the piston rod. The piston head is located inside the piston cylinder, and the piston rod passes through the through hole to connect to the piston head.
[0007] In a further technical solution, a discharge pipe is provided at the bottom of one end of the piston cylinder connected to the sampling tube, and a valve is provided on the discharge pipe.
[0008] In a further technical solution, a pull ring is provided at the end of the piston rod.
[0009] In a further technical solution, the sampling tube is threadedly connected to the piston cylinder.
[0010] In a further technical solution, the sampling tube comprises multiple tubes, which are respectively located at different heights on the side wall of the vessel.
[0011] In a further technical solution, the top of the vessel is provided with a vent pipe, and the top of the vent pipe is provided with a pipe cap.
[0012] The beneficial effects of this utility model are:
[0013] 1. A sampling piston is connected to a sampling tube to sample the material inside the vessel. During sampling, the valve on the sampling tube can be opened, and the material can be sucked out of the vessel by pulling the sampling piston. Due to the suction effect, the material with high viscosity and poor flowability can quickly flow into the sampling piston. When sampling again, the material remaining in the sampling tube can be extracted first, and the sampling tube valve can be closed. Then, the sampling piston can be disassembled relative to the sampling tube to discharge the residual material in the sampling piston. The above sampling operation can be repeated to obtain a sample, avoiding excessive residual material in the sampling pipe from affecting the sampling results.
[0014] 2. The sampling tube and sampling piston can be easily cleaned separately after being disassembled;
[0015] 3. With the discharge pipe installed, when using the sampling piston, there is no need to disassemble the sampling pipe multiple times. The sampled material can be discharged from the discharge pipe, making the operation more convenient.
[0016] 4. Multiple sampling tubes are installed at different positions on the vessel body to facilitate multi-point sampling and make the sampling results more accurate. Attached Figure Description

[0021] The embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0022] Example:
[0023] like Figures 1-2As shown, a convenient sampling reactor includes a reactor body 10 and a sampling structure. The reactor body 10 has an inlet 11 at the top and an outlet 12 at the bottom. The bottom edge of the reactor body 10 has support feet 13. The sampling structure includes a sampling tube 20 and a sampling piston 30. The sampling piston 30 includes a piston cylinder 31, a piston rod 32, and a piston head. One end of the piston cylinder 31 is open and communicates with the sampling tube 20. The other end has an end cap. The middle of the end cap has a through hole for matching the piston rod 32. The piston head is located inside the piston cylinder 31. The piston rod 32 passes through the through hole and connects to the piston head. A sampling port is opened on the side wall of the reactor body 10. For easy disassembly and cleaning, a connecting ring 14 can be installed at the sampling port. The two ends of the sampling tube 20 are threaded to the connecting ring 14 and the piston cylinder 31, respectively. Sealing rings can be installed at the threaded connections. A valve is installed on the sampling tube 20. A vent pipe 15 is provided at the top of the reactor body 10. A pipe cap 16 is provided at the top of the vent pipe 15.
[0024] The working principle of the above technical solution is as follows:
[0025] During sampling, connect the piston cylinder 31 to the sampling tube 20, open the valve on the sampling tube 20, and open the cap 16 of the vent pipe 15 to allow air to enter the vessel body 10 when the piston rod 32 is pulled, making it easier to pull the piston rod 32. When pulling the piston rod 32, first suck the material that was previously left in the sampling tube 20 into the piston cylinder 31, close the valve on the sampling tube 20, remove the piston cylinder 31 and discharge the remaining material, reset the piston rod 32, reconnect the sampling tube 20 and the piston cylinder 31, and repeat the above operation. At this time, the material is sucked from the vessel body 10 into the piston cylinder 31, and the valve on the sampling tube 20 and the vent pipe 15 are closed, completing one sampling.
[0026] In another embodiment, such as Figure 2 As shown, the bottom of one end of the piston cylinder 31 connected to the sampling tube 20 is provided with a discharge pipe 33, and a valve is provided on the discharge pipe 33.
[0027] When the material inside the piston cylinder 31 needs to be discharged, there is no need to disassemble the piston cylinder 31. The valve of the discharge pipe 33 can be opened directly, and the material inside the piston cylinder 31 can be discharged by the piston head. The operation is more convenient.
[0028] In another embodiment, such as Figure 2 As shown, the piston rod 32 has a pull ring 34 at its end.
[0029] The pull ring 34 makes it easy to push and pull the piston rod 32.
[0030] In another embodiment, such as Figure 1 As shown, there are multiple sampling tubes 20, which are respectively located at different heights on the side wall of the vessel body 10.
[0031] Multiple sampling points can be performed, resulting in more accurate sampling results. When sampling, simply remove the sampling piston 30 from one location and reinstall it at the sampling tube 20 where sampling is required.
[0032] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
