Description

Technical Field

[0001] This utility model relates to the field of chromatography technology, and in particular to a clinical gas chromatograph. Background Technology

[0002] Gas chromatograph is an instrument that uses chromatographic separation and detection techniques to perform qualitative and quantitative analysis on complex mixtures of multiple components. It can typically be used to analyze thermally stable organic compounds in soil with boiling points not exceeding 500°C, such as volatile organic compounds, organochlorines, organophosphorus compounds, polycyclic aromatic hydrocarbons, phthalates, etc.

[0003] The patent document publication number is CN219777583U, "A Clinical Gas Chromatograph," specifically relating to the field of gas chromatography equipment technology. It includes a chromatograph body for clinical use, with an outlet pipe fixedly connected to its rear end. A delivery pipe is fixedly connected to one side of the rear end of the outlet pipe. The delivery pipe has an L-shaped cross-section. A water tank is located at the front of the end of the delivery pipe furthest from the outlet pipe. A cooling pipe with a spiral cross-section is located inside the water tank. The end of the delivery pipe furthest from the outlet pipe penetrates the water tank and is fixedly connected to the rear end of the cooling pipe. An exhaust pipe is fixedly connected to the top of the front end of the cooling pipe. This utility model utilizes the outlet pipe... The design allows residual high-temperature gas from the gas chromatograph after operation to be transported to the outside via delivery pipes, cooling pipes, and exhaust pipes. To prevent direct discharge of the high-temperature gas and potential harm to the environment and personnel, it is cooled by water inside a water tank. The spiral-shaped cooling pipes allow the hot gas components to come into contact with the water, achieving better cooling. Currently, existing clinical gas chromatographs pose a significant safety hazard to personnel when the high-temperature gas they produce is discharged into the environment. Furthermore, the purity of the gas produced by the gas chromatograph is relatively poor, easily affecting the air quality of the surrounding working environment.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Please see Figure 1-8 This utility model provides a clinical gas chromatograph, including a gas chromatograph body 1, a support frame 2 fixed to one side wall of the gas chromatograph body 1, a cooling box 3 fixed to the top side wall of the support frame 2, an installation box 4 fixed to one side wall of the cooling box 3, a connecting pipe 5 fixed between the cooling box 3 and the installation box 4, a connecting pipe 6 fixed between the installation box 4 and the gas chromatograph body 1, and a cooling component 7 provided on one side of the cooling box 3.

[0029] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8As shown, it is worth noting that the cooling component 7 includes two symmetrically distributed brackets 71 fixed to the inner sidewall of the cooling chamber 3. A cotton core board 72 is fixed to both brackets 71. An air outlet pipe 73 connected to the interior is fixed to the top sidewall of the cooling chamber 3. The cotton core board 72 is located directly below the air outlet pipe 73. Two symmetrically distributed mounting frames 74 are fixed to the bottom sidewall of the support frame 2. A pump body 75 is fixed to the inner sidewall of both mounting frames 74. A water pipe a76 is fixed to the input end of the pump body 75, with one end of the water pipe a76 connected to the interior of the cooling chamber 3. A connected water pipe b77 is fixed to the output end of the pump body 75, connected to the interior of the cooling chamber 3. The water pipe b77 is located directly above the cotton core board 72. An atomizing generator 78 is fixed to the outer sidewall of the cooling chamber 3. Atomizing tube 79 is fixed to the inner side wall of the cooling chamber 3. One end of the atomizing tube 79 is fixed to the output end of the atomizing generator 78. Multiple atomizing nozzles 710 are fixed to the outer surface of the atomizing tube 79 at equal intervals. A flexible hose 711 is fixed between the input end of the atomizing generator 78 and the cooling chamber 3. Through the setting of the cooling component 7, the high-temperature gas generated by the gas chromatograph body 1 can be efficiently cooled, so that the high-temperature gas can fully contact the water mist in the cooling chamber 3, thereby achieving a better cooling purpose. The high-temperature hot gas remaining after the gas chromatograph body 1 is finished working is effectively transported to the outside through the cooling chamber 3. Moreover, it can effectively avoid the direct discharge of high-temperature hot gas, which may cause harm to the external environment and personnel, thereby reducing the safety hazards caused by high-temperature gas splashing.

[0030] Further as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 and Figure 8 As shown, it is worth noting that a gas filter assembly 8 is provided on one side of the mounting box 4. The gas filter assembly 8 includes multiple equally spaced through slots 81 on one side wall of the mounting box 4. Filter plates 82 are slidably connected inside the multiple through slots 81. A connecting plate 83 is fixed to one side wall of the multiple filter plates 82. A handle 84 is fixed to the top side wall of the connecting plate 83. A sealing ring 85 is tightly fitted to the outer side wall of the filter plate 82. The sealing ring 85 is in contact with one side of the mounting box 4. Through the setting of the gas filter assembly 8, the high-temperature gas generated by the gas chromatograph body 1 can be filtered and purified, thereby greatly improving the purity of the gas, effectively improving the air quality around the gas chromatograph body 1, improving the safety of the gas chromatograph body 1, having good practicality, and being simple to disassemble and assemble with low operation difficulty.

[0031] This solution has the following working process: When the technician uses this device, the high-temperature gas generated by the gas chromatograph 1 is discharged through the pipe 6. The gas is filtered and purified by multiple filter plates 82. After filtration, the gas enters the cooling chamber 3 through the connecting pipe 5. First, ensure that the water source in the cooling chamber 3 is at the scale groove 10. The water source in the cooling chamber 3 is drawn from the cooling chamber 3 by the atomizer 78 and the hose 711. The atomizer 78 and the atomizing nozzle 710 generate water mist to cool the high-temperature gas, achieving the purpose of cooling the high-temperature gas. Driven by the pump body 75, the water source is drawn and pressurized by the water pipe a76. The pressurized water source is then transported to the cotton core plate 72 by the water pipe b77, thereby ensuring that the cotton core plate 72 is in a relatively humid state, completing the cooling and filtration of the high-temperature gas.

[0032] As can be seen from the above working process, the cooling component 7 can efficiently cool the high-temperature gas generated by the gas chromatograph 1, allowing the high-temperature gas to fully contact the water mist in the cooling chamber 3, thereby achieving better cooling. This effectively transports the residual high-temperature gas from the gas chromatograph 1 after operation to the outside via the cooling chamber 3, and effectively prevents the direct discharge of high-temperature gas from harming the external environment and personnel, thus reducing safety hazards caused by high-temperature gas splashing. Furthermore, the filter component 8 can filter and purify the high-temperature gas generated by the gas chromatograph 1, significantly improving the purity of the gas and effectively improving the air quality around the gas chromatograph 1. This enhances the safety of the gas chromatograph 1 and has good practicality. Moreover, the disassembly and assembly are simple and the operation is easy.

[0033] Further as Figure 4 , Figure 6 and Figure 8 As shown, it is worth noting that the inner side wall of the bottom of the installation box 4 is provided with multiple symmetrically distributed limiting grooves 9. The limiting grooves 9 are located directly below the through groove 81. One side of the filter plate 82 is engaged with the inside of the limiting groove 9. The limiting grooves 9 can be used to position the filter plate 82 and prevent the filter plate 82 from being misaligned or shifted during installation and use.

[0034] Further as Figure 1 , Figure 2 , Figure 7 and Figure 8 As shown, it is worth noting that multiple atomizing nozzles 710 are located directly below the cotton core plate 72, and a scale groove 10 is provided on the inner side wall of the cooling box 3. A water inlet pipe 11 connected to the interior is fixed on the outer side wall of the cooling box 3.

[0035] Further as Figure 1 , Figure 7 and Figure 8 As shown, it is worth noting that the outer surface of the air outlet pipe 73 is provided with a threaded groove 13, and an airflow diffuser 12 is threadedly connected to the threaded groove 13. The setting of the airflow diffuser 12 and the threaded groove 13 makes it convenient for staff to disassemble, replace and maintain the airflow diffuser 12, which is more flexible and convenient.

[0036] Further as Figure 1 and Figure 7 As shown, it is worth noting that the central axis of the exhaust pipe 73 is collinear with the central axis of the airflow diffuser 12, and the vertical cross-section of the airflow diffuser 12 is trapezoidal. The airflow diffuser 12 diffuses the gas generated when the gas chromatograph body 1 is operating, thereby preventing the gas flow rate from being too high due to direct gas injection, which could cause injury to the staff.

[0037] In summary: the limiting groove 9 can position the filter plate 82, preventing misalignment or displacement during installation and use. The airflow diffuser 12 and threaded groove 13 facilitate easy disassembly, replacement, and maintenance by operators, offering high flexibility and convenience. Furthermore, the airflow diffuser 12 diffuses the gas generated during the operation of the gas chromatograph body 1, preventing excessive gas flow velocity caused by direct gas injection from harming operators.

[0038] The gas chromatograph body 1, the nebulizer 78, and the pump body 75 can all be purchased commercially. The gas chromatograph body 1, the nebulizer 78, and the pump body 75 are equipped with power supplies. This is a mature technology in the field and has been fully disclosed, so it will not be repeated in the specification.
