Description

Technical Field

[0001] This utility model relates to the field of detection technology, specifically a sampling and transfer module. Background Technology

[0002] In the field of air quality monitoring, whether it's ambient air quality monitoring (such as PM2.5, PM10, and volatile organic compound detection), indoor air safety monitoring, or industrial workshop exhaust emission monitoring, the accurate capture and analysis of target pollutants in the air are essential. Among these, the sampling cutter is the core device for achieving graded air sample collection. Its internal filter membrane (such as quartz, PTFE, or glass fiber membranes) is a crucial carrier for trapping particulate matter and adsorbing gaseous pollutants. Driven by an air pump, airflow passes through the filter membrane, causing suspended particulate matter, aerosols, or pre-treated gaseous pollutants to accumulate on or inside the membrane surface. Subsequently, the pollutant-laden filter membrane needs to be transferred to specialized detection equipment (such as particulate matter analyzers, gas chromatography-mass spectrometry, or infrared spectrometers). By adjusting the membrane's position within the detection equipment (such as aligning it with the detection light source, inlet, or analysis channel), quantitative analysis, component identification, or morphological characterization of the pollutants on the membrane can be achieved, ultimately obtaining key data such as the concentration and type of the target pollutants in the air.

[0003] Currently, the sampling and transfer operations of filter membranes in air quality testing mainly rely on two methods: one is manual operation, where the testing personnel wear clean gloves, use specialized tweezers, manually open the sealed door of the sampling cutter, remove the sampled filter membrane, and then manually adjust the position of the filter membrane and complete the installation according to the sampling requirements of the testing equipment. This method has certain drawbacks: on the one hand, manual operation can easily damage the filter membrane due to improper gripping force of the tweezers, or cause wrinkles in the filter membrane due to hand tremors, directly disrupting the enrichment morphology of pollutants on the filter membrane and affecting the accuracy of the test results; on the other hand, air quality testing requires extremely high filter membrane cleanliness, and fibers from gloves and dust in the environment can easily adhere to the filter membrane surface during manual operation, causing cross-contamination of pollutants, and the interference of contamination may lead to distorted test data. Utility Model Content

[0004] To address one of the shortcomings of existing technologies, this utility model provides a sampling transfer module that solves the problem of automatic transfer of the filter membrane of the sampling cutter.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a sampling and transfer module, comprising: A transfer mechanism includes a transfer component and a transfer frame, wherein the transfer component can support the filter membrane of the sampling cutter; the transfer frame and the transfer component are connected. The rotating mechanism, linked to the transfer frame, can drive the transfer frame to rotate horizontally; The lifting mechanism, which is linked to the transfer frame, can drive the transfer frame to rise or fall. An antistatic mechanism is provided on one side of the transfer mechanism to remove static electricity from the sampling cutter filter membrane on the transfer component.

[0006] Preferably, the transfer member includes: The support structure supports the sample cutter filter membrane and is a horizontal structure. The limiting structure includes a plurality of limiting blocks disposed around the periphery of the supporting structure, the limiting blocks extending upward toward the supporting structure; and the limiting blocks are distributed in a circular array around the periphery of the supporting structure. A connecting structure is provided on one side of the supporting structure, and the connecting structure is detachably connected to the transfer frame.

[0009] Preferably, it also includes: The transfer support frame includes a horizontally arranged top plate and a bottom plate, with at least one vertical plate between the top plate and the bottom plate; The frame rod of the transfer frame passes through the top plate of the transfer support frame and is movably connected to the top plate; the connecting piece is located above the top plate; The rotating mechanism and the lifting mechanism are respectively located between the top plate and the bottom plate.

[0010] Preferably, the rotating mechanism includes: The rotating motor is fixedly connected to the top plate or bottom plate; A rotation linkage assembly is disposed between the rotation motor and the frame rod, and the motor shaft of the rotation motor drives the frame rod to rotate through the rotation linkage assembly.

[0011] Preferably, the rotation linkage component includes: The rotating base is rotatably connected to the top plate; the frame rod passes through the rotating base and is vertically slidably connected to the rotating base. The rotation drive component is fixedly connected to the motor shaft of the rotation motor; A rotation linkage is disposed between the rotating base and the rotation drive component, and the rotation drive component is linked with the rotating base through the rotation linkage.

[0012] Preferably, the lifting mechanism includes: The lifting motor is fixedly connected to the top plate or the bottom plate; A lifting linkage assembly is installed between the lifting motor and the frame pole.

The antistatic module contains an ion generator that can release antistatic ions upwards. When the transfer component rotates above the static elimination mechanism, the ion release port of the static elimination module is located directly below the hollowed-out area in the middle of the transfer component.

[0015] Compared with existing technologies, this sampling transfer module has the following advantages: It can achieve mechanized support and transfer of the filter membrane of the sampling cutter through the coordinated action of the transfer mechanism, the rotation mechanism and the lifting mechanism. This avoids the filter membrane damage caused by improper clamping force of tweezers and the filter membrane wrinkling caused by hand tremors during manual operation. It effectively protects the enrichment morphology of pollutants on the filter membrane and provides a guarantee for the accuracy of subsequent test results.

[0016] This solution uses a mechanical structure to replace the manual direct contact with the filter membrane, reducing the possibility of external contaminants such as glove fiber shedding and environmental dust adhering to the filter membrane surface, significantly reducing the risk of cross-contamination, avoiding data distortion caused by contamination interference, and improving the reliability of the test data.

[0017] Meanwhile, by incorporating an antistatic mechanism, this solution can effectively remove static electricity accumulated on the filter membrane during the transfer process, ensuring that the filter membrane carrying the sample is in optimal condition when transferred to the detection equipment, which is beneficial for the smooth progress of subsequent detection operations.

[0020] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and 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 protection scope of this utility model.

[0021] Please see Figures 1-4 This application provides the following technical solutions: A sampling transfer module includes a transfer mechanism 1, a rotation mechanism 2, a lifting mechanism 3, and an antistatic mechanism 4. The transfer mechanism 1 includes a transfer component 11 and a transfer frame 12. The transfer component 11 supports the sample cutter filter membrane; the transfer frame 12 is connected to the transfer component 11. The rotation mechanism 2 is linked to the transfer frame 12, driving the transfer frame 12 to rotate horizontally. The lifting mechanism 3 is linked to the transfer frame 12, driving the transfer frame 12 to rise or fall. The antistatic mechanism 4 is located on one side of the transfer mechanism 1 and can remove static electricity from the sample cutter filter membrane on the transfer component 11.

[0022] In addition, as a supporting structure for the module, a transfer support frame 5 is also provided. The transfer support frame 5 is approximately an "I" shaped frame, including a horizontally arranged top plate 51 and bottom plate 52, with two parallel vertical plates 53 arranged between the top plate 51 and the bottom plate 52.

[0023] The sampling and transfer module in this solution is used in air quality testing equipment for sample transfer. The transfer component 11 supports the sample cutter filter membrane and transfers it between other testing structures. By incorporating an antistatic mechanism 4, the sample to be tested on the sample cutter filter membrane can be destaticated, ensuring smooth processing of the sample after transfer.

[0024] Based on the above implementation scheme, the transfer component 11 includes a support structure and a limiting structure, which are used in combination. The support structure is a horizontally arranged structure with an overall "C"-shaped frame structure. The interior of the support structure is a hollow area. The support structure must have an outer diameter larger than the outer diameter of the sampling cutter filter membrane and an inner diameter smaller than the outer diameter of the sampling cutter filter membrane. This ensures that the sampling cutter filter membrane will not fall off. The limiting structure consists of "L"-shaped limiting blocks arranged around the periphery of the support structure, extending upwards towards the support structure. Three limiting blocks are evenly distributed in a circular array around the periphery of the support structure. A connecting structure is provided on one side of the support structure, and the connecting structure is detachably connected to the transfer frame 12.

[0025] This structure supports the filter membrane of the sampling cutter and ensures that the filter membrane does not easily fall off.

[0026] Based on the above implementation scheme, the transfer frame 12 includes a frame rod 121 and a connector 122. The frame rod 121 is a vertically arranged rod, and the frame rod 121 is linked with the rotating mechanism 2 and the lifting mechanism 3 respectively. One end of the connector 122 is detachably connected to the upper part of the frame rod 121, and the other end is detachably connected to the transfer component 11 through a connecting structure.

[0027] The frame rod of the transfer frame 12 passes through the top plate 51 of the transfer support frame 5 and is movably connected to the top plate 51; the connecting piece is located above the top plate 51; the rotating mechanism 2 and the lifting mechanism 3 are respectively arranged between the top plate 51 and the bottom plate 52.

[0028] The transfer rack 12 in this solution has an extremely simple structure, making it suitable for use in small spaces and reducing the size of the testing equipment.

[0029] Based on the above implementation scheme, the rotating mechanism 2 includes a rotating motor 21 and a rotating linkage assembly 22. The rotating motor 21 is fixedly mounted on the base plate 52. The rotating linkage assembly 22 serves as a linkage structure between the rotating motor 21 and the support rod 121. The motor shaft of the rotating motor 21 drives the support rod 121 to rotate through the rotating linkage assembly 22.

[0030] The rotation linkage assembly 22 can adopt various structural forms, and this solution provides one of them. The rotation linkage assembly 22 of this solution includes a rotating seat 221, a rotation drive component, and a rotation linkage component. The rotating seat 221 is rotatably connected to the top plate 51. The rotating seat 221 is a cylindrical block with a through hole at its central axis and a guide groove on the inner wall of the through hole. A support rod 121 passes through the rotating seat 221, and a guide block is provided on the outer wall of the support rod 121 corresponding to the guide groove. Through the cooperation of the guide groove and the guide block, the support rod 121 is vertically slidably connected to the rotating seat 221 and can rotate synchronously with the rotation of the rotating seat 221. The rotation drive component is fixedly connected to the motor shaft of the rotating motor 21. The rotation drive component is a pulley, and a corresponding pulley structure is also provided at the lower part of the rotating seat 221. The rotation linkage component is a belt disposed between the rotating seat 221 and the rotation drive component. When it is necessary to rotate the transfer frame 12, the rotating motor 21 drives the rotating drive component to rotate, thereby driving the rotating seat 221 to rotate, so that the transfer frame 12 can achieve the corresponding angle of rotation.

[0031] Based on the above implementation scheme, the lifting mechanism 3 includes a lifting motor 31 and a lifting linkage assembly 32. The lifting motor 31 and the base plate 52 are fixedly connected by a small bracket, which is fixedly mounted on the base plate 52, and the lifting motor 31 is fixedly mounted on the upper side of the small bracket. The lifting linkage assembly 32 is disposed between the lifting motor 31 and the support rod 121, and the motor shaft of the lifting motor 31 drives the support rod 121 to rise or fall vertically through the lifting linkage assembly 32.

[0032] Similar to the rotating mechanism 2, the lifting linkage component 32 can also be implemented in various different forms. This solution provides one of them.

[0033] The lifting linkage assembly 32 includes a lifting seat 321, a lifting rod 322, and a guide rod 323. The lifting seat 321 is fixedly connected to the lower part of the support rod 121, and is located between the top plate 51 and the bottom plate 52. The lifting rod 322 is rotatably mounted between the top plate 51 and the bottom plate 52; the lifting rod 322 is a lead screw, and the lifting seat 321 and the lifting rod 322 are threadedly connected. The lifting rod 322 is linked to the lifting motor 31. Two guide rods 323 are arranged in parallel, both positioned between the top plate 51 and the bottom plate 52, and the lifting seat 321 and the guide rods 323 are slidably connected. A synchronous pulley and synchronous belt combination is provided between the lifting motor 31 and the lifting rod 322 to achieve linkage between the motor shaft of the lifting motor 31 and the lifting rod 322.

[0034] Through this structure, the lifting motor 31 drives the lifting rod 322 to rotate in different directions, thereby causing the lifting seat 321 to rise or fall, thus realizing the synchronous lifting and lowering of the frame rod 121.

[0035] Based on the above implementation scheme, the static eliminator 4 of this scheme includes a static eliminator module, which is located on one side of the top plate 51. The static eliminator module contains an ion generator for static elimination. When the transfer member 11 rotates above the static eliminator 4, the ion release port of the static eliminator module is located directly below the hollowed-out area in the middle of the transfer member 11. The ion generator can release positive and negative ions upwards to eliminate static electricity, thus achieving the static elimination operation on the sample.

[0036] Based on the above implementation scheme, a cover fastening mechanism 6 is provided on the upper side of the top plate 51 and at the edge of the top plate 51. The cover fastening mechanism 6 includes a cover bracket 61 on which the cover to be fastened can be placed.

[0037] A lifting frame is installed on the upper side of the top plate 51. The lifting frame includes a frame plate and a frame rod. The frame rod is a vertically arranged threaded rod, and the frame plate is spliced ​​into a plate-type support structure, which can be rotatably connected to the frame rod. A bracket seat is threadedly connected to the frame rod, and the cover bracket 61 is fixedly installed on the bracket seat. The bracket seat can be raised and lowered above the top plate 51. A cover-closing motor is installed corresponding to the frame rod. The cover-closing motor drives the frame rod through a combination of synchronous pulley and synchronous belt, thereby driving the cover bracket 61 to rise and fall. When the transfer member 11 rotates to the lower position, the cover bracket 61 descends and can cover the transfer member 11.

[0038] This structure takes into account that when testing the sampled samples, there may be certain testing steps that require covering the filter membrane of the sampling cutter.
