Abstract
Description
Technical Field
[0001] This utility model relates to the field of reaction vessels, and in particular to a reaction vessel sampling device. Background Technology
[0002] A reaction vessel is a container widely used in chemical, petroleum, food, pharmaceutical, pesticide, and scientific research fields. It is primarily used to achieve the various temperature and pressure conditions required for reaction experiments, enabling various chemical reaction processes. To ensure product quality and obtain real-time data during the reaction process within the reaction vessel, sampling and testing are necessary at each stage of the reaction.
[0003] Currently, the sampling process in a reactor involves discharging the liquid from the reactor through a valve located at the bottom. However, the liquid release is subject to pressure within the reactor, which causes spraying and splashing. This not only wastes the sample but also risks splashing onto the operators. High-temperature or corrosive liquids can easily cause injury to the operators.
[0004] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content
[0005] To address the aforementioned shortcomings, the purpose of this invention is to provide a reactor sampling device that can switch the level gauge between different states, enabling both level measurement and sampling; and during the sampling process, pressure is released, reducing splashing.
[0006] To achieve the above objectives, this utility model provides a reactor sampling device, including a reactor body and a level gauge disposed on its outer wall; the level gauge includes a liquid receiving tube parallel to the axis of the reactor body, which is connected to the reactor body through a connecting pipe to form a connected structure; a blocking valve is installed on the connecting pipe; a pressure regulating valve is disposed above the liquid receiving tube and a discharge valve is disposed below the liquid receiving tube.
[0007] According to the reaction vessel sampling device of this utility model, liquid scales are distributed along the axial direction on the wall of the liquid containing tube.
[0008] According to the sampling device for the reactor of this utility model, the pressure regulating valve is a three-way valve, which is connected to the liquid container pipe, the external environment and the pressure supply device respectively.
[0009] According to the sampling device for the reaction vessel of this utility model, a plurality of sampling ports are distributed along the axial direction on the wall of the liquid containing tube; the plurality of sampling ports are evenly distributed at equal intervals on the wall of the liquid containing tube.
[0010] According to the sampling device for the reactor of this utility model, the connection end of each sampling port is inclined downward and is equipped with a blocking valve; the connection end of the sampling port has a downward tilt angle S with the horizontal plane.
[0011] According to the sampling device for the reaction vessel of this utility model, the blocking valve is a one-way valve.
[0012] This invention provides a sampling device for a reaction vessel, including a reaction vessel body and a level gauge disposed on its outer wall. Under normal conditions (non-sampling state), the level gauge displays the liquid level of the reaction liquid within the reaction vessel body. Liquid graduations are distributed along the axial direction on the wall of the liquid receiving tube. These graduations can be directly disposed on the wall of the liquid receiving tube, or fixed to the outer wall of the level gauge using an adhesive or magnetic scale. The level gauge includes a liquid receiving tube parallel to the axis of the reaction vessel body. Typically, the liquid receiving tube is made of a high-pressure resistant transparent or semi-transparent material (such as glass). The liquid receiving tube is connected to the reaction vessel body via a connecting pipe, forming a connected structure. The liquid level in the liquid receiving tube is equal to the liquid level within the reaction vessel body. This invention allows the level gauge to be switched between different states, enabling both liquid level measurement and sampling. Furthermore, during sampling, pressure is released, reducing splashing. Attached Figure Description

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model.
[0019] See Figure 1 and Figure 2This invention provides a reactor sampling device, which includes a reactor body 1 and a level gauge 2 disposed on its outer wall. Under normal conditions (non-sampling state), the level gauge 2 is used to display the liquid level of the reaction liquid inside the reactor body 1. Liquid graduations are distributed along the axial direction on the wall of the liquid receiving tube 21. These graduations can be directly disposed on the wall of the liquid receiving tube 21, or fixed to the outer wall of the level gauge 2 using an adhesive or magnetic scale.
[0020] The level gauge 2 includes a liquid containing tube 21 parallel to the axis of the reactor body 1. Normally, the liquid containing tube 21 is made of a high-pressure resistant transparent or semi-transparent material (such as glass). The liquid containing tube 21 is connected to the reactor body 1 through a connecting pipe to form a connecting structure. The liquid level in the liquid containing tube 21 is equal to the liquid level in the reactor body 1.
[0021] A shut-off valve 3 is installed on the connecting pipe to isolate the internal space of the liquid receiving tube 21. After this operation, the pressure release of the internal space of the liquid receiving tube 21 will not affect the internal pressure of the reactor body 1. Multiple connecting channels are provided (in this embodiment, two connecting channels are provided to ensure that the pressure inside the liquid receiving tube 21 is equal to that inside the reactor body 1). A pressure regulating valve 4 is provided above the liquid receiving tube 21, and a discharge valve 5 is provided below it. The pressure regulating valve 4 is used to adjust the pressure inside the liquid receiving tube 21 (increase pressure or release pressure). The valve port of the discharge valve 5 can be used to discharge the liquid in the liquid receiving tube 21 and can also be used as a sampling port.
[0022] Before sampling, when the level gauge 2 is in the level measurement operation, the blocking valve 3 is opened, the pressure in the liquid receiving tube 21 is the same as that in the reaction vessel body 1, and the liquid flows into the level gauge 2.
[0023] When sampling is in progress, close the blocking valve 3 (to achieve pressure blocking), open the pressure regulating valve 4 above the level gauge 2 (at this time, the pressure inside the level gauge 2 is equal to atmospheric pressure), and at the same time open the discharge valve 5, so that the liquid inside the level gauge 2 flows out naturally.
[0024] To reset, close the discharge valve 5 and adjust the flow path of the pressure regulating valve 4.
[0025] Preferably, during the above reset process, there will be a decrease in pressure inside the reactor body 1 (this is because the pressure inside the level gauge 2 is equal to atmospheric pressure during reset). The pressure regulating valve 4 is a three-way valve, which is connected to the liquid container pipe 21, the external environment and the pressure supply device respectively.
[0026] During reset, close the discharge valve 5, adjust the passage of the pressure regulating valve 4, and use the pressure supply device to pressurize the pressure inside the level gauge 2 to be equal to the pressure inside the reactor body 1. Then, open the shut-off valve 3. This operation can ensure the stability of the pressure inside the reactor body 1.
[0027] See Figure 3 and Figure 4 In another embodiment, based on the above embodiment, a plurality of sampling ports 6 are distributed along the axial direction on the wall of the liquid containing tube 21; the plurality of sampling ports 6 are evenly distributed at equal intervals on the wall of the liquid containing tube 21. By connecting the sampling bottle to the sampling ports 6 at different positions, samples can be taken from different positions. The connection end of each sampling port 6 is inclined downward and is equipped with a shut-off valve 7; the connection end of the sampling port 6 has a downward tilt angle S with the horizontal plane. By setting the tilt angle, it can be ensured that the sampling state of the sampling bottle is also in the tilted state when connected, ensuring that the appropriate volume of sample is obtained (avoiding insufficient sample volume), and the shut-off valve 7 is a one-way valve, which facilitates rapid sampling of the sampling bottle. It is only necessary to insert the bottle through a specific opening into the shut-off valve 7, push open the sealing ball inside the shut-off valve 7, and the liquid flows out naturally.
[0028] In summary, this invention provides a sampling device for a reaction vessel, including a reaction vessel body and a level gauge disposed on its outer wall. Under normal conditions (non-sampling state), the level gauge displays the liquid level of the reaction liquid within the reaction vessel body. The liquid receiving tube has liquid graduations distributed along its axial direction on its wall. These graduations can be directly disposed on the wall of the liquid receiving tube, or fixed to the outer wall of the level gauge using an adhesive or magnetic scale. The level gauge includes a liquid receiving tube parallel to the axis of the reaction vessel body. Typically, the liquid receiving tube is made of a high-pressure resistant transparent or semi-transparent material (such as glass). The liquid receiving tube is connected to the reaction vessel body via a connecting pipe, forming a connected structure. The liquid level in the liquid receiving tube is equal to the liquid level within the reaction vessel body. This invention allows the level gauge to be switched between different states, enabling both liquid level measurement and sampling. Furthermore, during sampling, pressure is released, reducing splashing.
[0029] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
