Description

Technical Field

[0001] This utility model relates to the field of chemical technology, and in particular to a novel carbon disulfide unloading detection instrument. Background Technology

[0002] In the chemical industry, carbon disulfide is an important industrial raw material with strict operational requirements in both production and transportation. Due to its flammable, explosive, and toxic properties, it is often stored and transported using a water seal to prevent volatilization. However, the lack of effective detection devices in current technology leads to water from the water seal easily entering the unloading pump or storage tank along with the carbon disulfide during tanker loading or unloading, resulting in inaccurate carbon disulfide measurement. Therefore, there is an urgent need to develop a device that can quickly and efficiently detect the moisture content of carbon disulfide without affecting normal loading and unloading operations. Based on this, a novel carbon disulfide unloading detector is proposed. Utility Model Content

[0003] The purpose of this invention is to provide a novel carbon disulfide unloading detection instrument to solve the problems mentioned in the background art.

[0004] In order to solve the above technical problems, the present invention provides the following technical solution: a novel carbon disulfide unloading detector, including an expansion tube, wherein the input end of the expansion tube is connected to a temperature regulating component, the output end of the expansion tube is connected to an electric valve, a sleeve is connected to the expansion tube, and a detection component is installed on the sleeve (11).

[0005] Furthermore, the sleeve has stepped grooves for installing detection components.

[0006] Furthermore, the temperature regulating component includes an outer tube, baffles, infusion tubes, baffles (34) and connecting tubes, and the outer tube is connected to the input end of the expansion tube. Two baffles are connected inside the outer tube, and multiple infusion tubes are provided on the two baffles inside the outer tube, and the two ends of the infusion tubes are respectively connected to and fixed on the two baffles.

[0007] Furthermore, the outer sleeve is electrically connected to two connecting pipes.

[0008] Furthermore, multiple baffles are evenly distributed inside the outer tube, and the infusion tube is fixed through and fixed to the baffles.

[0009] Furthermore, the enlarged tube has a smaller diameter at both ends and a gradually increasing diameter towards the middle section.

[0010] The utility model provides a novel carbon disulfide unloading detector, the advantages of which are: the utility model slows down the flow rate of the material by expanding the tube and lowers the temperature of the carbon disulfide by the temperature regulating component, preventing some of the carbon disulfide from volatilizing into a gaseous state at high temperature, thereby making the carbon disulfide entering the expanding tube liquid, thus improving the accuracy of carbon disulfide moisture content detection.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0018] Please see the appendix Figure 1 -Appendix Figure 4One embodiment of this utility model is a novel carbon disulfide unloading detector, which includes an expansion tube 1, a temperature regulating component 3 connected to the input end of the expansion tube 1, an electric valve 4 connected to the output end of the expansion tube 1, a sleeve 11 connected to the expansion tube 1, and a detection component 2 installed on the sleeve 11.

[0019] By slowing down the flow rate of the material through the expansion tube and lowering the temperature of carbon disulfide through the temperature regulation component, some carbon disulfide is prevented from volatilizing into a gaseous state at high temperatures. This ensures that the carbon disulfide entering the expansion tube is in a liquid state, thereby improving the accuracy of carbon disulfide moisture content detection.

[0020] In this embodiment, the detection component 2 can be implemented using an existing structure. For example, it may include a controller 21 connected to an infrared moisture meter 22. A level gauge 23 is mounted on one side of the infrared moisture meter 22, and a capacitance sensor 26 is mounted on the other side. A conductivity meter 24 is mounted on one side of the level gauge 23, and a density meter 25 is mounted on the other side. A pressure sensor 27 is mounted on one side of the capacitance sensor 26, and a temperature sensor 28 is mounted on the other side. An expansion tube 1 provides a stable detection environment, a temperature regulating component 3 maintains a constant material temperature, and an electric valve 4 controls the opening and closing of the material conveying pipeline. The detection component 2 uses the infrared moisture meter 22 to detect moisture in the material. The moisture content is determined by measuring the conductivity of the material using a conductivity meter 24, the density of the material using a densitometer 25, and the capacitance of the material using a capacitance sensor 26. A level gauge 23 is used to detect the liquid level of the material, a pressure sensor 27 is used to detect the pressure in the expansion tube 1, and a temperature sensor 28 is used to detect the temperature of the material. A controller 21 is used to analyze and process the data, control the electric valve 4, and also for human-machine interaction. The controller 21 establishes electrical connections with the infrared moisture meter 22, level gauge 23, conductivity meter 24, densitometer 25, capacitance sensor 26, pressure sensor 27, temperature sensor 28, and electric valve 4. The specific implementation structure of the detection component 2 is not within the scope of protection of this utility model. It is understood that the detection component 2 can also consist of only a densitometer comprising a detector, a meter head, and a transmitter. The detector extends into the expansion tube, and the other end is connected to the meter head via the transmitter.

[0021] In one embodiment, a stepped groove 12 is provided inside the sleeve 11, and the controller 21 is threadedly connected to the stepped groove 12. The stepped groove 12 is used to install the controller 21. A sealing ring 13 is sleeved inside the stepped groove 12, and the sealing ring 13 is disposed at the bottom end of the controller 21. The sealing ring 13 is used to improve the sealing between the controller 21 and the stepped groove 12.

[0022] In one embodiment, the temperature regulating component 3 includes an outer sleeve 31, baffles 32, infusion tubes 33, baffles 34, and connecting tubes 35. The outer sleeve 31 is connected to the input end of the expansion tube 1. Two baffles 32 are connected inside the outer sleeve 31. Multiple infusion tubes 33 are provided inside the outer sleeve 31, and both ends of the infusion tubes 33 are connected to the two baffles 32 respectively. The baffles 32 are used to isolate the cooling medium and the material, the infusion tubes 33 are used to transport the material, and the outer sleeve 31 is used to provide a heat exchange site. Two connecting tubes 35 are connected to the outer sleeve 31. The connecting tubes 35 are used to input and output the cooling medium. Multiple baffles 34 are evenly distributed inside the outer sleeve 31, and the infusion tubes 33 are fixed through the baffles 34. The baffles 34 are used to extend the heat exchange time of the cooling medium and allow the cooling medium to fully fill the outer sleeve 31.

[0023] Working Principle: When using this invention, the material is input into the expansion tube 1 via the temperature regulating component 3, and then output via the electric valve 4. During this process, the detection component 2 uses an infrared moisture meter 22 to detect the moisture content of the material, a conductivity meter 24 to detect the conductivity of the material, a densitometer 25 to detect the density of the material, and a capacitance sensor 26 to detect the capacitance of the material. Because water and carbon disulfide have different absorption characteristics of infrared light, different conductivity, different density, and different capacitance, the controller 21 can analyze the moisture content of the material by combining the above data. When the moisture content reaches the threshold, the electric valve 4 is immediately controlled to shut off to prevent water from being transported to the unloading pump or storage tank along with the carbon disulfide. The sleeve 11 is used to install the controller 2 via the stepped groove 12. 1. The sealing ring 13 is used to improve the sealing between the controller 21 and the stepped groove 12. The level gauge 23 is used to detect the liquid level of the material. The pressure sensor 27 is used to detect the pressure in the expansion pipe 1. The temperature sensor 28 is used to detect the temperature of the material to ensure the safety of material transportation. The temperature regulating component 3 is used to keep the temperature of the material constant, thereby improving the accuracy of the detection results. The temperature regulating component 3 inputs the cooling medium into the outer tube 31 through one of the connecting pipes 35. After the cooling medium exchanges heat with the delivery pipe 33, it is output from the other connecting pipe 35. The delivery pipe 33 is used to transport the material. The baffle 32 is used to isolate the cooling medium and the material. The baffle 34 is used to extend the heat exchange time of the cooling medium and to allow the cooling medium to fully fill the outer tube 31.
