[0002] Infrared spectroscopy is a widely used analytical technique in chemistry, materials science, biomedicine, and other fields, primarily for qualitative and quantitative analysis of substances. During infrared spectroscopy, gaseous components such as moisture and carbon dioxide in the sample can interfere with the spectral measurements, leading to inaccurate results. To eliminate these interferences, the sample chamber is typically purged before measurement to remove interfering gases.

Detailed Implementation

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 scope of protection of this utility model.
[0029] Please see Figure 1 , Figure 2 and Figure 5 The present invention provides a technical solution: an infrared spectral purging device, comprising a base 110, a detection box 120 fixedly installed at the top of the base 110, a hinged sliding door at the top of the detection box 120, a mixing box 130 fixedly installed on one side of the detection box 120, a mixing component installed inside the mixing box 130, a plurality of air inlet pipes 131 installed on one side of the mixing box 130, one end of the air inlet pipe 131 passing through one side of the mixing box 130 and being inclined, a first solenoid valve installed on the air inlet pipe 131, an air intake unit fixedly installed on the other side of the mixing box 130, an infrared spectrometer body 121 fixedly installed on the outside of the detection box 120, an infrared detection probe fixedly installed at the output end of the infrared spectrometer body 121 and fixedly passing through the detection box 120, and a gas supply unit 150 fixedly installed on one side of the top of the base 110, the gas supply unit 150 being connected to the air inlet pipe 131 through a connecting pipe.
[0030] In some specific implementation schemes, an observation window 122 is provided on one side of the detection chamber 120, and an exhaust pipe is fixedly installed on the other side of the detection chamber 120. A sealing cap is threaded onto the outside of the exhaust pipe, and the exhaust pipe and the inlet unit are symmetrically arranged inside the detection chamber 120. This allows operators to easily observe the sample status and purging process inside the chamber at any time without frequently opening the sliding door, preventing the entry of external interfering gases and ensuring a stable detection environment. The exhaust pipe fixedly installed on the other side of the detection chamber 120, with a sealing cap threaded onto the outside of the exhaust pipe, can promptly expel interfering gases and waste gases from inside the chamber during purging. After purging, tightening the sealing cap prevents external gases from flowing back into the detection chamber 120, maintaining the purity of the gas environment inside the chamber and ensuring the accuracy of the detection results.
[0031] Please see Figure 3 The gas supply unit 150 includes a placement box 151, a gas storage tank 152, and a flow controller. The placement box 151 is fixedly installed on the top of the base 110. Multiple gas storage tanks 152 are placed inside the placement box 151. The output end of the gas storage tank 152 is connected to the inlet pipe 131 through a connecting pipe. The flow controller is installed at the output end of the gas storage tank 152. The two ends of the connecting pipe are respectively sleeved to the output end of the gas storage tank 152 and the inlet pipe 131.
[0032] In some specific implementations, multiple partitions are fixedly installed inside the placement box 151, dividing the interior of the placement box 151 into multiple chambers, each containing a gas storage tank 152. This design allows for the categorized storage of different types of gas storage tanks 152, preventing collisions and avoiding safety accidents. It also facilitates rapid identification and retrieval of specific gases, improving work efficiency, and helps maintain the independence and stability of the gas storage environment, preventing mutual interference between different gases.
[0033] Please see Figure 4 and Figure 6 The mixing assembly includes a flow divider 161 and a cylindrical mixing chamber 130. A rotating shaft 160 is rotatably mounted on one side of the inner wall of the mixing chamber 130, and a flow divider 161 is fixedly mounted on one end of the rotating shaft 160. The flow divider 161 is frustoconical. The air intake unit includes an air outlet cylinder 164 and an air outlet hole 165. An air outlet cylinder 164 is fixedly mounted on one side of the mixing chamber 130 and is internally connected. One end of the air outlet cylinder 164 is fixedly inserted through one side of the detection chamber 120 and extends to the inside. Multiple air outlet holes 165 are provided on the outer side of the air outlet cylinder 164.
[0034] In some specific implementations, the inclined surface of the diversion disk 161 is provided with multiple guide grooves 162 and multiple guide plates 163. The guide grooves 162 and guide plates 163 are arranged in an alternating ring. The diversion disk 161 is located at the center of the mixing chamber 130 and a gap is provided between it and its inner wall. The alternating arrangement of the guide grooves 162 and guide plates 163 guides the gas to form a complex flow path on the surface of the diversion disk 161, increasing the friction and collision between the gases, facilitating the rotation of the diversion disk 161, and further promoting gas mixing. The gap between the diversion disk 161 and the inner wall of the mixing chamber 130 allows the gas to circulate within the mixing chamber 130, making the mixing more thorough, improving the uniformity of the mixed gas, and thus enhancing the purging effect.
[0035] In some specific implementations, a display screen 170 is fixedly installed on one side of the detection chamber 120, and a gas detection sensor is installed inside the mixing chamber 130. The gas detection sensor is electrically connected to the display screen 170 and is used to monitor the composition and concentration of the purge gas in real time. By observing the data on the display screen 170, operators can promptly understand the real-time status of the purge gas. If abnormalities in gas composition or concentration are detected, adjustment measures can be taken quickly, such as adjusting the flow rate of the gas supply unit 150, to ensure that the purge gas meets the detection requirements, thereby ensuring the reliability of the infrared spectral analysis results.
[0036] Working Principle: Gas Preparation and Supply: Different types of purging gases are loaded into gas storage tanks 152 and placed in the respective chambers of the placement box 151. According to the testing requirements, the flow rate of gas output from each gas storage tank 152 is set via a flow controller. After the equipment is started, the gas in the gas storage tank 152 flows into the inlet pipe 131 through the connecting pipe. The first solenoid valve on the inlet pipe 131 controls the gas flow.
[0037] Gas mixing: The inclined air inlet pipe 131 allows gas to enter the mixing chamber 130 at a certain angle. The gas blowing drives the frustum-shaped distribution plate 161 to rotate. The guide grooves 162 and guide plates 163 arranged in an alternating ring on the inclined surface of the distribution plate 161 guide the gas flow, causing different gases to collide and diffuse with each other. Under the action of the guide grooves 162 and guide plates 163, the gas is fully mixed in the mixing chamber 130 to form a uniform gas mixture.
[0038] Gas purging in the detection chamber: The mixed gas enters the inlet unit and is evenly released into the detection chamber 120 through the outlet port 165 on the outlet pipe 164. The infrared detection probe inside the detection chamber 120 operates under the drive of the infrared spectrometer body 121 to detect the gas environment inside the chamber. During the purging process, the original interfering gas in the detection chamber 120 and the exhaust gas generated after purging are discharged through the outlet pipe.
[0039] Observation, venting, and sealing: Operators can observe the sample condition and purging process inside the chamber through the observation window 122 on one side of the detection chamber 120, without frequently opening the sliding door, thus preventing the entry of external interfering gases. During the purging process, the exhaust pipe is used to expel the gas inside the chamber; after purging, tighten the sealing cap on the outside of the exhaust pipe to prevent external gases from flowing back into the detection chamber 120 and maintain a stable gas environment inside the chamber.
[0040] Real-time monitoring and adjustment: The gas detection sensor inside the mixing chamber 130 monitors the composition and concentration of the purge gas in real time and transmits the data to the display screen 170 on one side of the detection chamber 120. Operators can observe the data on the display screen 170. If abnormalities are detected in the composition or concentration of the purge gas, the parameters of the flow controller in the gas supply unit 150 can be adjusted promptly to change the gas output flow rate of the gas storage tank 152, ensuring that the purge gas meets the detection requirements and guaranteeing the accuracy of the infrared spectroscopy analysis results.
