Description

Technical Field

[0001] This utility model relates to the field of gas sampling technology, specifically a gas sampling device. Background Technology

[0002] A gas sampling device is a device specifically designed to collect gas samples from a specific environment. Its core function is to provide accurate and representative gas samples for subsequent analysis and testing.

[0003] Gas sampling devices typically consist of key components such as a sampling probe, a vacuum pump, a gas path control system, and a sample container. Their working principle is based on negative pressure suction technology. The vacuum pump generates negative pressure, drawing the target gas into the device through the sampling probe. After pretreatment such as filtration and drying, the gas is stored in the sample container.

[0004] However, in actual use, most existing gas sampling devices only use simple filters or single adsorption materials for filtration. Simple filters cannot effectively filter out fine particles and harmful gas components, and single adsorption materials have limited adsorption capacity for different types of impurities, resulting in low purity of the sampled gas and affecting the accuracy of subsequent analysis and detection results. In view of this, we propose a gas sampling device. Utility Model Content

[0005] The purpose of this invention is to provide a gas sampling device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0016] Preferably, the mounting bracket is provided in multiple sets, the cleaning wipe is disposed above the filter cartridge, and the cleaning wipe is attached to the outer surface of the filter cartridge.

[0017] Compared with the prior art, the present invention provides a gas sampling device with the following advantages:

[0018] 1. In order to provide accurate and reliable samples for subsequent analysis and testing, this gas sampling device is equipped with a filter assembly. This assembly works in conjunction with a motor to drive a power gear through a connecting rod. The power gear meshes with the internal gear ring on the filter cylinder, causing the filter cylinder to rotate slowly. Multiple sets of filter plates inside the filter cylinder can initially filter larger particulate impurities in the gas. Multiple sets of adsorption plates are installed on the round rods between the filter plates.

[0019] 2. To improve the ease of use of this gas sampling device, an auxiliary component is included. This component works in conjunction with multiple mounting brackets on a circular mounting plate to fix the support frame. The support frame is equipped with a cleaning wiper via a mounting rod. The cleaning wiper is positioned above the filter cartridge and adheres to its outer surface. Since the filter cartridge is made of transparent glass, the cleaning wiper continuously wipes the outer surface of the filter cartridge during gas filtration as the filter cartridge rotates, removing adhering dust, stains, and other impurities. This operation ensures the cleanliness of the outer surface of the filter cartridge, allowing the operator to clearly observe the working status of the filter plates, adsorption plates, and other components inside the filter cartridge, as well as the gas filtration process.

[0028] Please see Figure 1 - Figure 5 This utility model provides a technical solution:

[0029] A gas sampling device includes a sampling device body 1, and a bracket 2 is fixedly installed at the bottom of the sampling device body 1.

[0030] In one embodiment of this utility model, a filter assembly 3 is provided on the sampling device body 1. The filter assembly 3 includes an annular mounting plate 31. The annular mounting plate 31 is fixedly mounted on the sampling device body 1. One end of a filter cylinder 32 is rotatably mounted on the sampling device body 1. A motor 33 is fixedly mounted on the annular mounting plate 31. One end of a connecting rod 34 is fixedly mounted on the output end of the motor 33. A power gear 35 is fixedly mounted on the other end of the connecting rod 34. An internal gear ring 36 is fixedly mounted on the filter cylinder 32. A filter plate 37 is fixedly mounted on the inner side of the filter cylinder 32. One end of a round rod 38 is rotatably mounted on the filter plate 37. An adsorption plate 3 is fixedly mounted on the round rod 38. 9. A thin rod 310 is fixedly installed at the other end of the round rod 38. A conical adsorption block 311 is fixedly installed on the thin rod 310. A sampling tube 312 is fixedly installed at the other end of the filter cylinder 32. Multiple sets of filter plates 37 and adsorption plates 39 are provided. The round rod 38 and multiple sets of adsorption plates 39 are arranged between multiple sets of filter plates 37. The filter plates 37, round rod 38, adsorption plates 39, thin rod 310 and conical adsorption block 311 are arranged inside the filter cylinder 32. The power gear 35 meshes with the internal gear ring 36. The number of teeth of the internal gear ring 36 is more than the number of teeth of the power gear 35. The filter cylinder 32 is connected to the air inlet of the sampling device body 1. The filter cylinder 32 is made of transparent glass.

[0031] In this embodiment, when the gas sampling device starts working, the motor 33 in the filter assembly 3 is first started. The motor 33 is fixed on the annular mounting plate 31 on the sampling device body 1. After the motor 33 starts, its output end drives the connecting rod 34 to rotate. The other end of the connecting rod 34 is fixed with a power gear 35. The rotation of the connecting rod 34 causes the power gear 35 to rotate accordingly. The power gear 35 meshes with the internal gear ring 36 on the filter cylinder 32, and the number of teeth of the internal gear ring 36 is more than the number of teeth of the power gear 35. This design realizes the deceleration function, so that the filter cylinder 32 can rotate slowly. One end of the filter cylinder 32 is rotatably mounted on the sampling device body 1 and connected to the air inlet of the sampling device body 1. External gas enters the interior of the filter cylinder 32 through the sampling tube 312 and is filtered. Multiple sets of filter plates 37 are installed inside the cylinder 32. These filter plates 37 can initially filter larger particulate impurities in the gas. Between the multiple sets of filter plates 37, a round rod 38 is rotatably mounted on the filter plates 37. Multiple sets of adsorption plates 39 are fixed on the round rod 38. A conical adsorption block 311 is installed on a thin rod 310 fixed to the other end of the round rod 38. As the filter cylinder 32 rotates slowly, the gas can fully contact the filter plates 37, adsorption plates 39 and conical adsorption blocks 311. The adsorption plates 39 and conical adsorption blocks 311 further adsorb small particles and harmful substances in the gas, thereby ensuring the filtration and adsorption effect of the gas and improving the purity of the sampled gas. The gas after sufficient filtration and adsorption enters the sampling device body 1, providing an accurate and reliable sample for subsequent analysis and detection.

[0032] In one embodiment of this utility model, an auxiliary component 4 is provided on the annular mounting plate 31. The auxiliary component 4 includes a mounting frame 41. One end of the mounting frame 41 is fixedly mounted on the annular mounting plate 31, and a support frame 42 is fixedly mounted on the other end of the mounting frame 41. A mounting rod 43 is fixedly mounted on the support frame 42, and a cleaning wipe 44 is fixedly mounted on the mounting rod 43. Multiple sets of mounting frames 41 are provided. The cleaning wipe 44 is located above the filter cartridge 32 and is attached to the outer surface of the filter cartridge 32.

[0033] In this embodiment, since the filter cartridge 32 is made of transparent glass, the cleaning wipe 44 attached to its outer surface can continuously wipe the outer surface of the filter cartridge 32 during the gas filtration process as the filter cartridge 32 rotates. This process can remove dust, stains and other impurities attached to the outer surface of the filter cartridge 32, ensuring the cleanliness of the outer surface of the filter cartridge 32. The cleanliness of the outer surface of the filter cartridge 32 allows the operator to clearly observe the working status of the internal components such as the filter plate 37 and the adsorption plate 39, as well as the gas filtration situation. Once an abnormality is found, the operator can deal with it in time, improving the convenience and reliability of the gas sampling device.

[0034] All electrical components appearing in this application are electrically connected to the controller and 220V AC mains power. The controller is a conventional and known device that can control the sampling device body 1 and the motor 33. All standard parts used in this application can be purchased from the market. The specific connection methods of each part are all conventional methods such as riveting and welding that are mature in the prior art. The machinery, parts and equipment are all conventional models in the prior art. In addition, the circuit connection adopts conventional connection methods in the prior art, and will not be described in detail here.

[0035] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
