Description

Technical Field

[0001] This utility model relates to the field of chemical product reaction vessel technology, specifically a chemical product reaction vessel that facilitates sampling. Background Technology

[0002] A chemical reaction vessel is a closed container used in chemical reaction processes. It typically consists of a vessel body, a jacketed or internal coil heating and cooling system, a stirring device, a sealing device, and inlet, outlet, and temperature and pressure measuring ports. It can complete the mixing, reaction, heat transfer, and mass transfer processes of materials under certain temperature and pressure conditions. Common materials are stainless steel, glass-lined steel, or alloy steel to adapt to the corrosiveness of different media and process requirements. It is widely used in industries such as chemical, pharmaceutical, dye, coating, and food.

[0003] Existing reactors often present challenges in assessing the chemical reaction status during the reaction process, requiring periodic sampling to ensure effective detection. However, for some high-pressure vessels and high-pressure reaction conditions, sampling within the reactor typically requires waiting until the reaction has stopped before depressurization and sampling can be conveniently performed. This operation necessitates repressurization to continue the reaction if it is not yet complete, which is quite inconvenient. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a chemical reaction vessel that facilitates sampling. It has the advantage of being able to conveniently sample under high pressure to determine the reaction process. This solves the problem that for some high-pressure containers and high-pressure reaction conditions, sampling inside the reaction vessel usually requires waiting for the reaction to stop before convenient depressurization and sampling can be performed. This operation is inconvenient because the pressure needs to be increased again to continue the reaction before it is complete.

[0006] (II) Technical Solution

[0007] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A chemical product reaction vessel for convenient sampling includes a vessel body. A sampling connecting sleeve extending to the outside and with its opening facing the outside of the vessel body is fixedly provided on the inner bottom wall of the vessel body. A sampling plug is slidably connected inside the sampling connecting sleeve to block it and form a seal. A driving component for driving the sampling plug to move is provided outside the sampling connecting sleeve. A multi-layer sampling component is connected to the bottom of one end of the sampling connecting sleeve located outside the vessel body.

[0008] The inner bottom wall of the sampling connecting sleeve is inclined and has a horizontal fold. The shape and size of the sampling plug are adapted to the inner wall of the sampling connecting sleeve. The top of the sampling connecting sleeve is provided with a sampling hole extending to the inner bottom wall at its end. The multi-layer sampling element is located at the fold of the inner bottom wall of the sampling connecting sleeve.

[0009] Based on the above technical solution, the present invention can be further improved as follows.

[0010] Furthermore, the driving component includes a driving frame fixed to the outside of the sampling connecting sleeve, and the driving frame has a driving rod whose end is rotatably connected to the sampling plug.

[0011] Furthermore, the multi-layer sampling device includes a sampling sleeve connected to a sampling connecting sleeve. Multiple cutting plates extending into the outside of the sampling sleeve and forming a partition between the internal space of the sampling sleeve are inserted therein. Multiple sampling plungers extending into the outside of the sampling sleeve and corresponding to the positions of the cutting plates are provided therein. A discharge valve is connected to the bottom of the sampling sleeve.

[0012] Furthermore, the multi-layer sampling device also includes a heat insulation unit fixed to the outside of the sampling sleeve and extending into its interior, wherein the heating end of the heat insulation unit is multiple and extends to the bottom of the corresponding cut plate.

[0013] Furthermore, the sampling sleeve has an observation window on its exterior, and the observation window is equipped with corrosion-resistant transparent glass that separates the interior and exterior spaces.

[0014] Furthermore, the top of one end of the cut-off plate inside the sampling sleeve is inclined, and the exterior of the cut-off plate is polished and has a corrosion-resistant coating.

[0015] This invention provides a chemical reaction vessel for convenient sampling. By setting up a sampling connecting sleeve, under normal conditions, the chemical product reacts inside the vessel. When sampling is required, a driving component drives the sampling plug to move. During this movement, a gap appears between the side wall of the sampling plug and the inner wall of the sampling connecting sleeve. Guided by the sampling hole, the chemical product flows through the gap into the multi-layer sampling components to complete the overall sampling operation. After sampling, the driving component can reset the sampling plug and close the gap again. At this time, the sampling hole can effectively drain the liquid, effectively preventing some liquid from accumulating at the connection point during the reaction and causing inaccurate sampling data. When multiple sampling operations at different time periods are required, the above operation can be repeated at fixed time periods. Furthermore, during the sampling process, the internal sealed space is not connected to the outside, providing the advantage of convenient sampling under high pressure to determine the reaction process.

[0020] 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.

[0021] Please see Figure 1-3 This utility model provides a chemical product reaction vessel for convenient sampling, including a vessel body 1. A sampling connecting sleeve 2 is fixedly provided on the inner bottom wall of the vessel body 1, extending to the outside and with its opening facing the outside of the vessel body 1. A sampling plug 3 is slidably connected inside the sampling connecting sleeve 2 to block it and form a seal. A driving component 4 is provided on the outside of the sampling connecting sleeve 2 to drive the sampling plug 3 to move. A multi-layer sampling component 5 is connected to the bottom of one end of the sampling connecting sleeve 2 located outside the vessel body 1.

[0022] The inner bottom wall of the sampling connecting sleeve 2 is inclined and has a horizontal fold. The shape and size of the sampling plug 3 are adapted to the inner wall of the sampling connecting sleeve 2. The top of the sampling connecting sleeve 2 is provided with a sampling hole 21 extending to the inner bottom wall at its end. The multi-layer sampling element 5 is provided at the fold of the inner bottom wall of the sampling connecting sleeve 2.

[0023] In this embodiment, the driving component 4 includes a driving frame 41 fixed to the outside of the sampling connecting sleeve 2, and a driving rod 42 with its end rotatably connected to the sampling plug 3 is threaded inside the driving frame 41.

[0024] When the drive unit 4 with the above configuration is working, it is only necessary to rotate the drive rod 42 to drive the sampling plug 3 to start moving horizontally under the action of the thread, thereby realizing the drive of the sampling plug 3.

[0025] In this embodiment, the multi-layer sampling member 5 includes a sampling sleeve 51 connected to the sampling connecting sleeve 2. Multiple cutting plates 52 extending into the outside of the sampling sleeve 51 and forming a partition between the internal space of the sampling sleeve 51 are inserted therein. Multiple sampling plungers 53 extending into the outside of the sampling sleeve 51 and corresponding to the positions of the cutting plates 52 are provided therein. A discharge valve 54 is connected to the bottom of the sampling sleeve 51.

[0026] The multi-layer sampling unit 5 with the above configuration can divide the internal space into multiple storage spaces through multiple cut-off plates 52, so that the sampled chemicals can be temporarily stored inside, and chemicals for multiple reaction time periods can be sampled and stored separately. When it is necessary to take out the sampled chemicals, they can be extracted directly by inserting a syringe or other components into the sampling plunger 53.

[0027] During use, all the cutting plates 52 can be moved first so that their ends do not contact the inner wall of the sampling sleeve 51, so that the sampling liquid can reach the bottom space. Then, the cutting plates 52 can be moved in sequence according to the sampling status to divide the space, thereby realizing the sampling of multiple groups of chemical products.

[0028] In this embodiment, the multi-layer sampling member 5 also includes a heat preservation unit 55 fixed to the outside of the sampling sleeve 51 and extending into its interior. The heating ends of the heat preservation unit 55 are multiple and extend to the bottom of the corresponding cut plate 52.

[0029] The insulation unit 55 is designed to maintain the original reaction temperature after the chemical product leaves the reactor body 1, preventing large errors in the sampling data caused by temperature changes.

[0030] In this embodiment, the sampling sleeve 51 has an observation window on the outside, and the observation window is equipped with corrosion-resistant transparent glass that separates the inner and outer spaces.

[0031] The observation window, combined with corrosion-resistant transparent glass, can effectively control the amount of chemical products entering the sampling unit 51, preventing overflow into another sampling space after a single sampling area is filled, thereby preventing mutual interference between different sampling spaces.

[0032] Furthermore, the top of one end of the cutting plate 52 located inside the sampling sleeve 51 is inclined, and the exterior of the cutting plate 52 is polished and has a corrosion-resistant coating.

[0033] The inclined top of the cut-off plate 52 with the above-described configuration can effectively drain the liquid during liquid discharge, thereby preventing residue.
