Description

Technical Field

[0001] The utility model relates to the technical field of gas analysis, and more specifically to a micro condenser for a gas analyzer. Background Art

[0002] A gas analyzer is an instrument used to detect and analyze gas composition. It is widely used in environmental monitoring, industrial process control, medical diagnosis and other fields.

[0003] In order to ensure the accuracy and reliability of the analysis results, the gas analyzer needs to have the characteristics of high sensitivity and high selectivity. In the gas analysis process, the moisture in the sample gas often becomes an interference factor. The presence of water vapor may cause errors and affect the accurate measurement of the gas composition. Therefore, in order to eliminate the interference of moisture, a condenser is usually added. For example, in the prior art, the patent with the authorization announcement number CN212301474U discloses a constant pressure and constant current gas analyzer protection device. However, the water collected in the water collecting tank is discharged to the drain pipe through the water collecting tank. When it is subsequently processed, the water in the water collecting tank can only be discharged and processed by opening the device door, which makes the processing method too cumbersome and inconvenient to use. Therefore, in response to this problem, the utility model proposes a micro condenser for a gas analyzer. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a micro condenser for a gas analyzer which can overcome the above problems or at least partially solve the above problems.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] Preferably, the impeller guide member includes a guide tube vertically connected to the air guide pipe, a driving unit is installed at the bottom of the guide tube, a connecting shaft rotatably connected to the top wall of the guide tube is fixed to the output end of the driving unit, and a plurality of circumferentially distributed impeller blades are fixed to the connecting shaft.

[0008] Preferably, a plurality of circumferentially distributed connecting strips are fixed to the top of the guide tube, and the tops of the connecting strips are fixed to the inner top wall of the instrument housing.

[0009] Preferably, the drainage component includes a water receiving box connected to the inner bottom wall of the instrument housing, the top opening of the water receiving box corresponds to below the bottom end of the water diversion pipe, one side of the water receiving box is connected to a drainage pipe extending to one side of the instrument housing, the inner wall of the water receiving box is slidably connected to a corresponding pressure plate, and a plurality of elastic elements are provided between the bottom of the pressure plate and the inner bottom wall of the water receiving box.

[0010] Preferably, the drain pipe has an inclined structure of fifteen degrees.

[0011] Preferably, the elastic element comprises a spring, and the spring is fixed between the pressure plate and the inner bottom wall of the water receiving box.

[0012] Preferably, a telescopic rod is sleeved inside the spring and is fixed between the pressure plate and the inner bottom wall of the water receiving box.

[0013] Preferably, support feet are fixed to the bottom of the instrument housing near the four corners, and the corresponding diameters of the support feet gradually increase from the top to the bottom.

[0014] After adopting the above technical scheme, the utility model has the following beneficial effects compared with the prior art: the gas analyzer uses a micro condenser, through the coordinated cooperation of structures such as a water receiving box, a drain pipe, a pressure plate, a spring and a telescopic rod. When the pressure of the water collected on the inner pressure plate in the water receiving box is greater than the spring force, the pressure plate will press down along the inner wall of the water receiving box, so that the channel corresponding to the drain pipe located on the inner wall of the water receiving box is located above the water receiving box, thereby automatically discharging the water in the water receiving box located on the pressure plate, which is more convenient than the traditional method of opening the device door.

[0025] In the utility model, when the water level pressure at the top of the pressure plate 43 in the water receiving box 41 is greater than the elastic force of the spring 441, the pressure plate 43 will slide along the inner wall of the water receiving box 41 until the top of the pressure plate 43 is lower than the drain pipe 42 connected to the inner wall channel of the water receiving box 41, and the water on the pressure plate 43 will be discharged to the outside of the instrument housing 1 through the drain pipe 42. Such an automated drainage method is more convenient than the traditional method of handling the discharge by opening the device door. In addition, in the present technical solution, there are other related micro-condensers for gas analyzers that are not mentioned in detail, all of which belong to the prior art.
