Description

Technical Field

[0001] This utility model relates to the field of elemental analysis technology, and in particular to a dustproof sample chamber for a gold ore atomic absorption spectrometer. Background Technology

[0002] The sample chamber structure of the gold ore atomic absorption spectrometer includes a main chamber, which serves as the core housing space. The chamber is equipped with a sealed door and sealing elements to enhance airtightness. Inside, there is a sample rack or fixing device for stably placing sample containers. The rack can be equipped with an adjustment mechanism to adjust its position. The chamber wall has openings for optical path channels to ensure the passage of light. Some sections are equipped with detachable liquid receiving components for collecting dripping liquids, as well as cleaning auxiliary structures such as flow guides or dust collection components.

[0003] However, the sample chambers of existing gold ore atomic absorption spectrometers still have the following problems: First, the dust protection during the sampling process is insufficient. Traditional sample chambers use a manual sampling port opening method. At the moment of opening, the outside air and the inside of the sample chamber form convection, and dust falls directly into the sample or adheres to the surface of the sample container. Especially in dusty environments such as gold mine beneficiation workshops, the risk of contamination is higher, directly leading to poor repeatability of test results. Second, the sealing operation relies on manual operation. Traditional sealing doors need to be closed manually, which is not only cumbersome, but may also cause the sealing components to fail due to dust or grease carried by the operator's hands. At the same time, uneven force during manual operation can easily cause wear on the sealing components, shorten their service life, and increase maintenance costs. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a dustproof sample chamber for a gold ore atomic absorption spectrometer, aiming to improve the problems of easy intrusion of external dust, poor sealing of the sampling port, cumbersome sampling process, and easy contamination of internal components of the instrument in the sample chamber of the gold ore atomic absorption spectrometer in the prior art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a dustproof sample chamber for a gold ore atomic absorption spectrometer, comprising a sample box, a sampling mechanism installed on the front side of the outer wall of the sample box, the sampling mechanism being used to reduce the intrusion of external dust into the sample box during sampling, a sealing mechanism installed on the top of the outer wall of the sample box, the sealing mechanism being used to reduce the entry of dust into the sample box during manual sealing operations, the sampling mechanism comprising a fixing box, the fixing box being installed on the front side of the outer wall of the sample box, a sampling plate being fixedly connected to the rear side of the outer wall of the fixing box, a pin being installed on the front side of the outer wall of the sampling plate, a rotating shaft being rotatably connected to the middle of the inner wall of the sampling plate, a fixing column being fixedly connected to the middle of the inner wall of the fixing box, and a rotating assembly being installed on the rear side of the outer wall of the fixing column.

[0006] Preferably, the rotating assembly includes a servo motor mounted on the top of the outer wall of the fixed column. A first gear tooth is fixedly connected to the output end of the servo motor. A second gear tooth is fixedly connected to the middle of the outer wall of the rotating shaft. The first gear tooth and the second gear tooth mesh with each other. A connecting plate is mounted on the rear side of the outer wall of the second gear tooth. A sealing valve is fixedly connected to the right side of the outer wall of the connecting plate. A sampling tube is disposed in the middle of the outer wall of the sealing valve. The sealing mechanism includes a fixed frame fixedly connected to the right side of the outer wall of the sample box. A first connecting shaft is rotatably connected to the right side of the outer wall of the fixed frame. A fixed block is fixedly connected to the middle of the outer wall of the first connecting shaft. A second connecting shaft is rotatably connected to the top of the outer wall of the fixed frame. A limit block is fixedly connected to the left side of the outer wall of the fixed frame. A driving assembly is mounted on the top of the outer wall of the limit block.

[0007] Preferably, the driving assembly includes an electric actuator, which is installed in the middle of the inner wall of the fixed block. A fixed tube is fixedly connected to the output end of the electric actuator. A connecting block is rotatably connected to the left side of the outer wall of the fixed tube. A dust cover is fixedly connected to the bottom of the outer wall of the connecting block, and a sealing ring is fixedly connected to the middle of the outer wall of the dust cover.

A thermometer is installed on the top of the outer wall of the sample box. A viewing glass is installed on the left side of the outer wall of the sample box.

[0008] This utility model has the following beneficial effects: 1. In this utility model, the servo motor inside the fixed box is started, and the first gear tooth drives the second gear tooth to rotate. The second gear tooth and the connecting plate are fixed in the middle of the rotating shaft. Therefore, when the second gear tooth rotates, it drives the connecting plate to rotate, which in turn drives the sealing valve to rotate inside the sampling plate. When it rotates to fit with the sampling tube, the sampling is completed and sealed. The rear pin can lock the current position. The automatic rotating gate can reduce the intrusion of external dust during sampling, enhance the sealing of the sampling port, reduce operational interference, simplify the sampling process, reduce detection deviation, and ensure the cleanliness of the sample chamber.

There is a sealing ring on the outer side of the dust cover on the left side of the connecting block. The limiting block on the left side of the fixed frame restricts the rotation range of the dust cover. The automatic flipping of the cover can reduce the dust brought in by manual operation, enhance the sealing stability, reduce operation error, improve the dustproof effect, simplify the process, and ensure a clean testing environment.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0013] Reference Figure 1 , Figure 3 and Figure 4This utility model provides an embodiment of a dustproof sample chamber for a gold ore atomic absorption spectrometer, comprising a sample box 1. A sampling mechanism 2 is installed on the front side of the outer wall of the sample box 1 to reduce the intrusion of external dust into the sample box 1 during sampling. A sealing mechanism 3 is installed on the top of the outer wall of the sample box 1 to reduce the entry of dust into the sample box 1 during manual sealing operations. The sampling mechanism 2 includes a fixing box 201, which is installed on the front side of the outer wall of the sample box 1. A sampling plate 202 is fixedly connected to the rear side of the outer wall of the fixing box 201. A pin 203 is installed on the front side of the outer wall of the sampling plate 202. A rotating shaft 204 is rotatably connected to the middle of the inner wall of the sampling plate 202. A fixing column 205 is fixedly connected to the middle of the inner wall of the fixing box 201. A rotating assembly 206 is installed on the rear side of the outer wall of the column 205. The rotating assembly 206 includes a servo motor 2061. The servo motor 2061 is an SGMMV servo motor 2061. Precise positioning and speed control are achieved through a closed-loop control system and encoder feedback. The servo motor 2061 is installed on the top of the outer wall of the fixed column 205. A gear tooth 2062 is fixedly connected to the output end of the servo motor 2061. A gear tooth 2063 is fixedly connected to the middle of the outer wall of the rotating shaft 204. Gear tooth 2062 and gear tooth 2063 are meshed. A connecting plate 2064 is installed on the rear side of the outer wall of gear tooth 2063. A sealing valve 2065 is fixedly connected to the right side of the outer wall of the connecting plate 2064. A sampling tube 2066 is provided in the middle of the outer wall of the sealing valve 2065.

[0014] The servo motor 2061, installed in the fixed box 201, is activated. The output power is transmitted through the meshing of gear 2062 and gear 2063, causing gear 2063 to rotate. Gear 2063 and connecting disc 2064 are fixedly connected to the middle of the rotating shaft 204, forming a synchronous rotation structure. When gear 2063 rotates, it drives the connecting disc 2064 to rotate coaxially, driving the sealing valve 2065 to rotate within the sealing cavity of the sampling plate 202. When the sealing valve 2065 rotates to fully engage with the interface of the sampling tube 2066... It can automatically complete the sealing operation after sampling. At this time, pushing the pin 203 backward into the positioning hole can lock the current position of the sealing valve 2065, ensuring a stable sealing state. The automatic rotating gate-type sealing structure can reduce the intrusion of external dust and other impurities during sampling, significantly enhance the sealing performance of the sampling port, reduce the interference of environmental factors on the sampling operation, simplify the manual sealing operation process, effectively ensure the cleanliness of the sample chamber, reduce detection deviations caused by contamination, and prevent impurities from entering the instrument and causing component wear, thus extending the service life of the equipment.

[0015] Reference Figure 1 , Figure 2 and Figure 5The sealing mechanism 3 includes a fixed frame 301, which is fixedly connected to the right side of the outer wall of the sample box 1. A connecting shaft 302 is rotatably connected to the right side of the outer wall of the fixed frame 301. A fixing block 303 is fixedly connected to the middle of the outer wall of the connecting shaft 302. A connecting shaft 304 is rotatably connected to the top of the outer wall of the fixed frame 301. A limiting block 305 is fixedly connected to the left side of the outer wall of the fixed frame 301. A driving assembly 306 is installed on the top of the outer wall of the limiting block 305. The driving assembly 306 includes an electric push rod 3061. 3061 adopts the electric actuator 3061 of LAP22. The electric actuator 3061 is driven by a motor and a lead screw to convert the rotary motion into linear motion to realize the actuator action. The electric actuator 3061 is installed in the middle of the inner wall of the fixed block 303. The output end of the electric actuator 3061 is fixedly connected to the fixed tube 3062. The left side of the outer wall of the fixed tube 3062 is rotatably connected to the connecting block 3063. The bottom of the outer wall of the connecting block 3063 is fixedly connected to the dust cover 3064. The middle of the outer wall of the dust cover 3064 is fixedly connected to the sealing ring 3065.

[0016] The electric push rod 3061, installed on the right side of the fixed frame 301, outputs driving force to linearly move the gear teeth 2062, which in turn drive the meshing gear teeth 2063 to rotate on the fixed frame 301 via the connecting shaft 304. The electric push rod 3061 is mounted on the connecting shaft 302 via the outer fixed block 303, allowing the electric push rod 3061 to rotate flexibly around the connecting shaft 302 on the right side of the fixed frame 301, adapting to angle changes during transmission. The dust cover 3064, fixed on the left side of the connecting block 3063, has a sealing ring 3065 on its outer side to enhance the sealing performance when closed. The limiting block 305, fixed on the left side of the fixed frame 301, precisely limits the rotation range of the dust cover 3064, preventing excessive rotation from causing structural damage. The automatic flip-top structure reduces the risk of dust intrusion caused by manual operation, enhances the stability of the sealing state, reduces errors caused by improper manual operation, significantly improves the dustproof effect, simplifies the operation process, and provides reliable support for ensuring the cleanliness of the testing environment.

[0017] Reference Figure 1 , Figure 2 and Figure 3 A fixing plate 4 is fixedly connected to the bottom of the outer wall of sample box 1. Screws 5 are threadedly connected to the four corners of the outer wall of fixing plate 4. A thermometer 6 is installed on the top of the outer wall of sample box 1. A viewing glass 7 is installed on the left side of the outer wall of sample box 1. Sample box 1 is externally connected to the inside of the spectrometer via the fixing plate 4 and multiple screws 5 installed at its bottom, which facilitates disassembly and installation when replacement is needed. The thermometer 6 installed on the top of sample box 1 is used to detect the temperature information inside sample box 1, while the viewing glass 7 installed on the left side of sample box 1 is used to observe the sample inside sample box 1 and related operating procedures.

[0018] Working principle: The servo motor 2061 installed in the fixed box 201 is started, which drives the gear 2063 to rotate via gear 2062. Gear 2063 and connecting plate 2064 are fixed in the middle of the rotating shaft 204. Therefore, when gear 2063 rotates, it drives the connecting plate 2064 to rotate, which in turn drives the sealing valve 2065 to rotate within the sampling plate 202. When it rotates to match the sampling tube 2066, the sealing operation after sampling is completed. Moving the pin 203 backward can lock the current position. The automatic rotating gate can reduce the intrusion of external dust during sampling, enhance the sealing of the sampling port, reduce operational interference, simplify the sampling process, ensure the cleanliness of the sample chamber, reduce detection deviation, and extend the service life of the internal components of the instrument.

[0019] The electric push rod 3061, installed on the right side of the fixed frame 301, is activated. The movement of gear tooth 2062 drives gear tooth 2063 to rotate on the fixed frame 301 via connecting shaft 304. The electric push rod 3061 rotates on the right side of the fixed frame 301 via the connecting shaft 302 mounted on the outer fixed block 303. A sealing ring 3065 is provided on the outer side of the dust cover 3064 fixed on the left side of the connecting block 3063. The limiting block 305 fixed on the left side of the fixed frame 301 is used to limit the rotation range of the dust cover 3064. The automatic flipping of the cover can reduce dust intrusion caused by manual operation, enhance sealing stability, reduce operation error, improve dust prevention effect, simplify operation process, and ensure a clean testing environment.
