Description

Technical Field

[0001] This utility model relates to the field of tobacco detection technology, and in particular to a water-based colloid gas chromatography-mass spectrometry instrument for tobacco. Background Technology

[0002] Water-based adhesives are crucial auxiliary materials in cigarette production, and their quality directly impacts the quality and safety of cigarettes. These adhesives may contain various harmful components such as vinyl acetate, benzene compounds, and halogenated hydrocarbons. Excessive levels of these components can pose potential health risks to smokers. Therefore, the national tobacco industry maintains extremely strict quality control over water-based adhesives, requiring accurate testing of the content of various components.

[0003] However, while mass spectrometry can perform effective qualitative analysis, it is ineffective for analyzing complex organic compounds. Chromatography is an effective separation and analysis method for organic compounds, especially suitable for quantitative analysis, but qualitative analysis is more difficult. Some methods use gas chromatography-mass spectrometry (GC-MS), but the inconvenience of quickly connecting and assembling the GC and mass spectrometer reduces the efficiency of the instruments. Therefore, we propose a water-based colloid gas chromatography-mass spectrometry system to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a gas chromatography-mass spectrometry (GC-MS) instrument for water-based colloids in tobacco products. This instrument combines the separation capabilities of gas chromatography with the high sensitivity and strong qualitative ability of mass spectrometry, effectively detecting the components in water-based colloids in tobacco products. Furthermore, it facilitates rapid connection and assembly of the gas chromatograph and mass spectrometer, improving the efficiency of the instrument.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a gas chromatography-mass spectrometry instrument for detecting water-based adhesives in tobacco, comprising a base, wherein a gas chromatograph, a mass spectrometer, and a data processing controller are detachably and fixedly connected to the top of the base for detecting water-based adhesives in tobacco; a pump body is fixedly connected to one side of the mass spectrometer on the base; both the pump body and the side of the gas chromatograph adjacent to each other are fixedly connected to a connection port; a flexible tube is connected between the two connection ports; a quick-connect sealing mechanism is provided between the flexible tube and the connection port; and an alarm is fixedly connected to the top of the data processing controller.

[0006] A further feature of this invention is that the data processing controller is equipped with a data processing system, and both the gas chromatograph and the mass spectrometer are electrically connected to the data processing system. The data processing system includes a data acquisition module, a data analysis module, and a result output module.

[0007] By adopting the above technical solution, the components in the water-based colloid sample of tobacco are separated and analyzed by gas chromatography, and the separated components are analyzed by mass spectrometry. The data acquisition module of the data processing system collects the data generated by the gas chromatography unit and the mass spectrometry unit in real time. The data analysis module can analyze and process the data, and the result output module displays the final detection results on the display screen of the data processing controller.

[0008] A further feature of this invention is that: a vacuum sensor and a vacuum pump are fixedly connected to the top of both the gas chromatograph and the mass spectrometer; the top of both the gas chromatograph and the mass spectrometer are respectively connected to the corresponding vacuum pump; a temperature sensor is fixedly connected to the top of both the gas chromatograph and the mass spectrometer; heaters are fixedly connected to the front and rear sides of both the gas chromatograph and the mass spectrometer; a flow meter is installed on the left-side connection port; and both the flow meter and the pump body are electrically connected to the data processing controller.

[0009] By adopting the above technical solutions, vacuum degree, temperature and flow rate can be measured separately through vacuum sensors, temperature sensors and flow meters. In case of abnormality, the data processing controller will activate the alarm and provide fault diagnosis information to help users quickly locate and solve problems, reducing instrument downtime. The vacuum degree in the gas chromatograph and mass spectrometer can be adjusted through the vacuum pump and vacuum sensor, the temperature of the gas chromatograph and mass spectrometer can be controlled through the heater and temperature sensor, and the flow rate of water-based colloid samples can be controlled through the pump body and flow meter, thereby improving the detection accuracy.

[0010] A further feature of this invention is that two ear plates are fixedly connected to the front and rear sides of both the gas chromatograph and the mass spectrometer, and screws are fixedly connected to the top of the ear plates, which are then fixedly connected to the top of the base by the screws.

[0011] By adopting the above technical solution, the gas chromatograph and mass spectrometer are fixed to the top of the base through the setting of ear plates and screws.

[0012] The present invention is further configured as follows: the quick-connect sealing mechanism includes a retaining ring fixedly sleeved on the outside of the connection port and a connector fixedly sleeved on the outside of the hose. An annular groove is formed on the inner wall of the connector, and a sealing ring is sleeved in the annular groove. An annular airbag is fixedly connected to the outside of the sealing ring, and four inclined blocks are fixedly connected to the outside of the annular airbag. Four extrusion plates are fixedly connected to one side of the retaining ring, and the four extrusion plates movably abut against the inclined surfaces of the corresponding inclined blocks. The sealing ring movably abuts against the outside of the connection between the connection port and the hose. The quick-connect sealing mechanism also includes four cavities formed in the connector and four through holes formed on one side of the retaining ring. Two limiting ports are formed on the upper and lower inner walls of the through holes. A rotating rod is rotatably connected to one inner wall of the cavity. A disc is fixedly sleeved on the outside of the rotating rod. The same torsion spring is fixedly connected between the disc and the cavity. Limiting blocks are fixedly connected to the front and rear sides of the rotating rod, and both limiting blocks movably abut against one side of the retaining ring.

[0013] By employing the above technical solution, the limiting block and rotating rod are moved to align the limiting block with the limiting port. Then, the connector is pressed, causing the rotating rod to insert into the through hole and the limiting block to insert into the limiting port until the retaining ring abuts against the connector. At this point, the limiting block slides out of the limiting port. Under the torque of the torsion spring, the rotating rod and the limiting block return to their original positions. Under the limitation of the limiting block, both ends of the hose can be connected to the corresponding connectors to facilitate rapid connection between the gas chromatograph and the mass spectrometer. Simultaneously, when the connector approaches the retaining ring, the extrusion plate will insert into the annular groove and gradually extrude the inclined blocks. This causes the four inclined blocks to move inward and extrude the annular airbag. The annular airbag will gradually expand inward and firmly press the sealing ring against the connection between the connector and the hose, resulting in a better seal and preventing leakage of the water-based adhesive sample.

[0014] A further feature of this invention is that a bearing is fixedly connected to one side of the inner wall of the cavity, the rotating rod is fixedly sleeved inside the bearing, and the torsion spring is sleeved on the outside of the rotating rod.

[0015] By adopting the above technical solution, the rotating rod can be supported, making its rotation more stable, and the torsion spring can be guided, making its torsion more smooth.

[0016] The beneficial effects of this utility model are:

[0017] 1. This utility model involves moving the limiting block and rotating rod to align the limiting block with the limiting port, then pressing the connector to insert the rotating rod into the through hole and the limiting block into the limiting port until the retaining ring abuts against the connector. At this point, the limiting block slides out of the limiting port. Under the torque of the torsion spring, the rotating rod and the limiting block return to their original positions. Under the limitation of the limiting block, both ends of the hose can be connected to the corresponding connectors for quick connection between the gas chromatograph and the mass spectrometer. Simultaneously, when the connector approaches the retaining ring, the extrusion plate will insert into the annular groove and gradually extrude the inclined blocks. This causes the four inclined blocks to move inward and extrude the annular airbag. The annular airbag will gradually expand inward and firmly press the sealing ring against the connection between the connector and the hose, resulting in a better seal and preventing leakage of water-based adhesive samples.

[0018] 2. This utility model uses a gas chromatograph to separate and analyze the components in a water-based colloid sample, and a mass spectrometer to perform mass spectrometry analysis on the separated components. The data acquisition module in the data processing system collects data generated by the gas chromatograph unit and the mass spectrometer unit in real time. The data analysis module can analyze and process the data, and the result output module displays the final detection results on the display screen of the data processing controller.

[0019] 3. This utility model uses a vacuum sensor, a temperature sensor, and a flow meter to measure vacuum, temperature, and flow rate respectively. In case of any abnormality, the data processing controller will activate the alarm and provide fault diagnosis information to help users quickly locate and solve problems, reducing instrument downtime. The vacuum pump and vacuum sensor can be used to adjust the vacuum level in the gas chromatograph and mass spectrometer. The heater and temperature sensor can be used to control the temperature of the gas chromatograph and mass spectrometer. The pump and flow meter can be used to control the flow rate of water-based colloid samples, thereby improving detection accuracy. Attached Figure Description

[0031] Specifically, a flow meter 15 is installed on the connection port 10 on the left side, and both the flow meter 15 and the pump body 14 are electrically connected to the data processing controller 12.

[0032] Specifically, the gas chromatograph 2 and the mass spectrometer 3 are both fixedly connected to two ear plates 8 on their front and rear sides. The top of the ear plates 8 is fixedly connected to a screw 7, and the ear plates 8 are fixedly connected to the top of the base 1 by the screw 7.

[0033] Specifically, the quick-connect sealing mechanism 9 includes a retaining ring 901 fixedly sleeved on the outside of the connection port 10 and a connector 902 fixedly sleeved on the outside of the hose 11. An annular groove 903 is provided on the inner wall of the connector 902. A sealing ring 907 is sleeved in the annular groove 903. An annular airbag 906 is fixedly connected to the outside of the sealing ring 907. Four inclined blocks 905 are fixedly connected to the outside of the annular airbag 906. Four compression plates 904 are fixedly connected to one side of the retaining ring 901. The four compression plates 904 are movably abutting against the inclined surface of the corresponding inclined block 905.

[0034] Specifically, the sealing ring 907 is in contact with the outside of the connection between the connector 10 and the hose 11.

[0035] Specifically, the quick-connect sealing mechanism 9 also includes four cavities 910 opened in the connector 902 and four through holes 912 opened on one side of the retaining ring 901. Two limiting ports 915 are opened on the upper and lower inner walls of the through holes 912. A rotating rod 913 is rotatably connected to one inner wall of the cavity 910.
