Description

Technical Field

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

[0002] Reactors are widely used in petroleum, chemical, rubber, pesticide, dye, pharmaceutical and food industries. They are pressure vessels used to complete processes such as vulcanization, nitration, hydrogenation, hydrocarbonation, polymerization and condensation. Examples include reactors, reaction vessels, decomposition vessels, polymerization vessels, etc. The materials generally include carbon manganese steel, stainless steel, zirconium, nickel-based alloys (Hastelloy, Monel, Inconel) and other composite materials.

[0003] Existing reactors often involve sampling by directly opening the reactor to create an open port. However, reactors are greatly affected by environmental changes during the reaction process, which can easily disrupt their operation during sampling. Therefore, we have specially designed a reactor sampling device. Utility Model Content

[0034] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0035] Example 1:

[0036] This embodiment provides a reactor sampling device, including:

[0037] The main body 1 has an input terminal 11 at its front end and an output terminal 12 at its rear end.

[0038] Pumping component 2 is installed inside the main body 1 and is connected to the input end 11 and the output end 12;

[0039] Sample container 3 is located at the rear end of the main body 1 and is connected to the output end 12;

[0040] The main body 1 has an opening 13 on its wall, through which the pumping component 2 is exposed.

[0041] As can be seen from this embodiment, a reaction vessel sampling device includes a main body 1, a pumping component 2, and a sample container 3;

[0042] The front section of the main body 1 has an input end 11, and the rear end of the main body 1 has an output end 12. The pumping component 2 is installed inside the main body 1, and both ends of the pumping component 2 are connected to the input end 11 and the output end 12. The sample tank 3 is connected to the output end 12. Furthermore, an opening 13 is provided on one side wall of the main body 1, and the pumping component 2 is exposed through the opening 13 to form a pressing surface.

[0043] When in use, after the input end 11 is connected to the probe port on the reactor, the operator presses the exposed part of the pumping component 2 through the open port 13 and changes the air pressure in the pumping component 2 and the sample tank 3. At this time, the solution in the reaction chamber will enter the pumping component 2 through the input end 11 under pressure and flow into the sample tank 3 (the pumping component 2 needs to be pressed quickly to form a pressure difference during use). At the same time, the first one-way valve 4 can restrict the solution entering the pumping component 2 from flowing back into the reactor.

[0044] Sampling can be performed without disrupting the reaction environment inside the reactor. The sampling method is simple and reliable, and the structure is simple, practical, and easy to carry and use.

[0045] Example 2:

[0046] This embodiment provides a reactor sampling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0047] Pumping component 2 includes:

[0048] The main body 21 has connectors 211 at both ends and a cavity inside.

[0049] Exhaust pipe 22 is located on one side of body 21, and a second one-way valve 23 is connected to exhaust pipe 22.

[0050] The connectors 211 at both ends of the main body 21 are connected to the input terminal 11 and the output terminal 12, respectively.

[0051] As can be seen from this embodiment, the pumping component 2 includes a body 21 and an exhaust pipe 22;

[0052] The body 21 is made of rubber material and is elliptical in shape. Connectors 211 are formed at both ends and are connected to the input end 11 and output end 12 at the front and rear ends of the body 1, respectively. The exhaust pipe 22 is formed on one side of the body 21 and a second one-way valve 23 is connected to the exhaust pipe 22.

[0053] During use, by quickly pressing the main body 21, the gas inside the main body 21 is discharged through the second one-way valve 23, causing the pressure inside the main body 21 and the sample tank 3 to be lower than the pressure inside the reaction vessel. Then, the solution is transported to the sample tank 3 by the pump under pressure for collection.

[0054] Example 3:

[0055] This embodiment provides a reactor sampling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0056] Diaphragm 5 is disposed on the opening 13 and covers the outside of the body 21;

[0057] The diaphragm 5 has connecting edges 51 on both sides, and the connecting edges 51 are movable to the two sides of the opening 13.

[0058] As can be seen from this embodiment, by providing a diaphragm 5 on the opening 13 to protect the main body 21, the service life of the device can be improved. Furthermore, a connecting edge 51 is installed on the diaphragm 5, and the diaphragm 5 is movably connected to the main body 1 through the connecting edge 51, which facilitates maintenance and replacement.

[0059] Example 4:

[0060] This embodiment provides a reactor sampling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0061] A slot 511 is provided on the connecting edge 51, and the slot 511 is tightly fitted and fixed to the two side walls of the open opening 13.

[0062] Among them, protruding edges 14 are provided on both sides of the open opening 13, and limiting edges 141 are provided on the protruding edges 14. A limiting groove 5111 is provided in the slot 511 corresponding to the limiting edge 141.

[0063] As can be seen from this embodiment, the connecting edge 51 is integrally formed on both sides of the diaphragm 5 (the connecting edge 51 and the diaphragm 5 are integrally injection molded, and the connecting edge 51 is thicker than the diaphragm 5). A slot 511 is provided on the end face of the connecting edge 51. A protruding edge 14 is formed on the end face of the main body 1 on both sides of the opening 13. The end of the protruding edge 14 is a limiting edge 141. A limiting groove 5111 is formed inside the slot 511 corresponding to the limiting edge 141. After the protruding edge 14 and the slot 511 are engaged, the limiting edge 141 is limited and engaged in the limiting groove 5111, thereby fixing the connecting edge 51 to the main body 1. The connection method is simple, reliable and easy to use.

[0069] This embodiment provides a reactor sampling device, which, in addition to the technical solutions of the above embodiments, also has the following technical features.

[0070] The protruding structure 6 is provided on the body 21 and exposed through the opening 13.

[0071] As can be seen from this embodiment, by providing a protruding structure 6 on the main body 21, it is convenient for staff to press during use.
