[0055] As part of the creative concept of the present application, before describing the embodiments of the present application, it is necessary to analyze the causes of the health hazards and the impact on the normal operation of the equipment caused by the presence of dust during the use of the spectrometer in the relevant technology, and obtain the technical solution of the embodiments of the present application through reasonable analysis.

[0056] In the related technology, direct reading spectrometer is an experimental detection device used to detect the type and content of elements. During the experiment, the high temperature generated by the arc or spark causes the elements in the sample to be directly vaporized from the solid state and excited, thereby emitting spectra with characteristic wavelengths of each element. These characteristic spectra are separated by gratings to form spectra arranged by wavelength. The characteristic spectral lines in the spectrum pass through the exit slit and enter their respective photomultiplier tubes. In this process, the optical signal is converted into an electrical signal to realize the detection of the sample.

[0057] Inert gas, such as argon, is used during the experiment to ensure the stability of the experimental environment and avoid environmental factors that may affect the experimental results. At the same time, the experiment will produce metal dust mixed with various elements such as carbon powder.

[0058] Since the dust generated is small in size, it is easy to escape in the air, and the experimental environment needs to be filled with inert gas to avoid the influence of impurities in the environment, making the dust drift phenomenon more obvious. Dust escapes with the gas, which will pollute the surrounding environment. On the one hand, the dust is inhaled by the surrounding staff, which will endanger the health of the staff; on the other hand, the dust drifts and falls to different areas, which will also affect the normal operation of the equipment. For example, if it falls on the circuit board, it may cause damage to the equipment. If it falls on other pipes and other locations, it also needs to be cleaned regularly, otherwise the dust from the previous experiment will affect the results of the next experiment and cause errors.

[0059] To this end, the present application provides a spectrometer dust collection device to solve the technical problems existing in the prior art of endangering the health of workers and affecting the normal operation of equipment.

[0060] The technical solutions of the embodiments of the present application are described in detail below in conjunction with the accompanying drawings. The technical features involved in the different implementation modes of the present application described below can be combined with each other as long as there is no conflict between them.

[0061] A spectrometer dust collection device is provided in an embodiment of the present application. For the convenience of description, the "spectrometer dust collection device" is referred to as the "collection device" in the embodiment of the present application below.

[0062] refer to Figure 1 The collecting device includes a collecting tube 1 and a connecting channel 2. The collecting tube 1 is used to store an adsorption liquid for adsorbing dust. In the embodiment of the present application, an ethanol solution is used as the adsorption liquid for explanation; one end of the connecting channel 2 is connected to the exhaust tail end of the spectrometer, and the other end is passed into the interior of the collecting tube 1, and the end located in the collecting tube 1 is located below the liquid level; in addition, an exhaust hole 13 is also opened on the collecting tube 1, and the exhaust hole 13 is located above the liquid level.

[0063] Dust is generated during the operation of the spectrometer. Driven by the argon gas flow, the dust is discharged into the connecting channel 2 through the outlet end of the spectrometer and enters the adsorption liquid along the connecting channel 2. The gas is insoluble in the adsorption liquid and escapes from the adsorption liquid and is discharged from the exhaust hole 13 to the outside of the collection tube 1, while the dust is adsorbed by the adsorption liquid and remains in the collection tube 1. In this way, the dust generated during the operation of the spectrometer is collected to avoid dust dispersion, which may endanger the health of the staff or affect the normal use of the spectrometer and the accuracy of the experimental test results.

[0064] Moreover, after completing the connection of the corresponding pipelines, the dust can be automatically collected. The staff does not need to perform manual operation during the process. They only need to clean the collection tube 1 or replace the collection tube 1 after the dust collection amount of the collection tube 1 reaches saturation, which improves the convenience of use.

[0065] refer to Figure 1 The collecting device further comprises a box body 3, the collecting cylinder 1 and the connecting channel 2 are both located in the box body 3, and the end of the connecting channel 2 away from the collecting cylinder 1 penetrates the box body 3 to the outside of the box body 3; of course, in other embodiments, the collecting cylinder 1 and the connecting channel 2 may be integrated without the box body 3, but the collecting cylinder 1 and the connecting channel 2 may be used in combination. In the embodiment of the present application, the method of setting the box body 3 is taken as an example for explanation.

[0066] refer to Figure 1 and Figure 2 The collecting cylinder 1 comprises a cylinder 11 with an opening at one end and a cover plate 12 for closing the opening of the cylinder 11, and the cover plate 12 is sealed and connected to the cylinder 11. The connecting channel 2 penetrates the cover plate 12 to achieve communication between the inside and outside of the collecting cylinder 1. In addition, the exhaust hole 13 is also opened on the cover plate 12.

[0067] refer to Figure 2 and Figure 3 The connection channel 2 includes a connection pipe 21, a transfer pipe 22 and an introduction pipe 23 which are interconnected, wherein the connection pipe 21 is connected to the gas outlet tail end of the spectrometer. Exemplarily, one end of the connection channel 2 connected to the gas outlet tail end of the spectrometer is set as a flared structure, and is sealed and connected to the gas outlet tail end of the spectrometer to reduce the phenomenon that argon mixed with dust is discharged from the gap between the connection pipe 21 and the gas outlet tail end of the spectrometer, so that the generated dust is collected more thoroughly and the effect is better.

[0068] The introduction tube 23 is located in the collection tube 1, fixedly connected to the cover plate 12, and communicated with the outside of the collection tube 1; one end of the introduction tube 23 away from the cover plate 12 is passed below the liquid level of the adsorption liquid. One end of the transfer tube 22 is fixedly connected to the connecting tube 21, and the other end is detachably fixedly connected to the cover plate 12, and the position where the transfer tube 22 is connected to the cover plate 12 corresponds to the position where the introduction tube 23 is connected to the cover plate 12, so as to realize the communication between the introduction tube 23 and the transfer tube 22.

[0069] For example, the number of collecting barrels 1 can be adjusted according to actual needs, for example, the number of collecting barrels 1 used and working at the same time can be set to one, two, three, four, etc. Correspondingly, the number of transfer tubes 22 and the number of introduction tubes 23 are the same as the number of collecting barrels 1, and correspond one to one with the collecting barrels 1. In the embodiment of the present application, two collecting barrels 1 are in working state at the same time as an example for explanation, that is, two transfer tubes 22 and two introduction tubes 23 are also provided.

[0070] Compared with the method of using a single collection tube 1, the convenience of collecting dust can be further improved, and a larger amount of dust can be continuously collected. When the adsorption amount of the two collection tubes 1 reaches saturation, the two collection tubes 1 are cleaned or replaced. Compared with a single collection tube 1, the number of times the collection tube 1 needs to be inspected and disassembled is reduced. Although the two collection tubes 1 are operated each time, it is more convenient than operating a single collection tube 1 at a higher frequency.

[0071] refer to Figure 2 The transfer tube 22 includes a first transfer section 221 and a second transfer section 222 which are sealed and connected. The first transfer section 221 is fixedly connected to the connecting tube 21, and the second transfer section 222 is detachably fixedly connected to the cover plate 12. The second transfer section 222 is movably connected to the first transfer section 221 in a direction approaching or moving away from the collecting tube 1. The collecting tube 1 and the transfer tube 22 can be separated or connected more conveniently.

[0072] For example, the collection tube 1 is placed on a plane, and the adapter tube 22 is connected to the cover plate 12. When the two need to be separated, the second adapter section 222 is moved away from the collection tube 1 to separate it from the cover plate 12, and then the collection tube 1 can be moved horizontally and taken out. When the two are connected, the collection tube 1 is first translated to the corresponding position, and then the second adapter section 222 is moved to connect it to the cover plate 12, so that the overall connection of the connection channel 2 can be achieved. By setting the second adapter section 222 to move relative to the first adapter section 221, the convenience of the use process is greatly improved.

[0073] refer to Figure 2, the adapter tube 22 also includes a telescopic section 223, and the first adapter section 221 and the second adapter section 222 are connected through the telescopic section 223; illustratively, the telescopic section 223 is a bellows, which connects the first adapter section 221 and the second adapter section 222, and realizes the movable connection between the first adapter section 221 and the second adapter section 222. When adjusting the second adapter section 222, the second connecting section is directly moved to drive the telescopic section 223 (bellows) to stretch or contract, which is more convenient to use. Of course, in other embodiments, the telescopic section 223 can also be set to other different types, for example: the telescopic section 223 is a tubular structure in which multiple sections are mutually sleeved and can slide against each other.

[0074] In order to further improve the convenience of using the collection device, in some embodiments, reference Figure 4 The collecting device further includes a driving member 4, which is connected between the first transfer section 221 and the second transfer section 222, and is used to drive the second transfer section 222 to move relative to the first transfer section 221. In this way, in the specific operation process, it is not necessary for personnel to manually adjust the second transfer section 222, which is convenient to use and more efficient.

[0075] Exemplarily, the driving member 4 is an electric push rod, and the two ends of the electric push rod are respectively fixedly connected to the first transfer section 221 and the second transfer section 222, and the position of the second transfer section 222 is adjusted by the action of the electric push rod. In other embodiments, the driving member 4 can also adopt a linear telescopic structure such as a cylinder or a hydraulic cylinder, or a structure of winding a traction rope, or a structure of a screw and a slider, as long as it can adjust the position of the second transfer section 222.

[0076] If the collection tube 1 needs to be replaced during the experimental test, the efficiency of replacing the collection tube 1 will affect the efficiency of the experiment. In order to further improve the convenience of replacing the collection tube 1 and improve the replacement efficiency, refer to Figure 1 The collection device further includes a dispatching mechanism 5, which is used to drive the collection barrel 1 to reciprocate between the working position and the pick-and-place position. The working position and the pick-and-place position are two spaces in the box body 3. When the collection barrel 1 is in the working position, the connecting channel 2 is in a connected state as a whole, and the dust collection process is carried out; when the collection barrel 1 is in the pick-and-place position, the transfer tube 22 and the cover plate 12 are in a separated state, that is, the connecting channel 2 is disconnected as a whole, and the collection barrel 1 is operated, such as cleaning or replacing.

[0077] For ease of understanding, refer to Figure 1 , the two collecting barrels 1 on the left side of the figure are in the working position, and the two collecting barrels 1 on the right side are in the picking and placing position.

[0078] Exemplarily, the dispatching mechanism 5 is provided with a first placement area and a second placement area for placing the collecting tube 1. When the first placement area is located at the working position, the second placement area is located at the placement position; when the first placement area is located at the placement position, the second placement area is located at the working position.

[0079] In the initial state, the first placement area and the second placement area are both placed with collection tubes 1. The first placement area is moved to the working position through the operation of the dispatching mechanism 5, and the corresponding collection tube 1 is connected to the transfer tube 22 for dust collection. At this time, the second placement area is located in the pick-up and placement position, and the corresponding collection tube 1 is in a standby state.

[0080] After the amount of dust collected by the collecting tube 1 in the first placement area reaches saturation, the adapter tube 22 is first separated from the cover plate 12, and the dispatching mechanism 5 moves the first placement area to the pick-and-place position. At the same time, the second placement area is moved to the working position, and then the adapter tube 22 is connected to the corresponding cover plate 12, and the collecting tube 1 in the second placement area starts to collect dust; when the collecting tube 1 in the first placement area moves to the pick-and-place position, the staff can remove it and perform subsequent operations. The normal dust collection process will not be affected during the process, which greatly improves the convenience of use and replacement efficiency and reduces delays to the experimental process of normal production.

[0081] Exemplarily, the dispatching mechanism 5 includes a turntable 51 and a power member 52. The turntable 51 is rotatably connected to the housing 3 and is used to carry the collecting barrel 1. The power member 52 is fixedly connected to the housing 3, and the output end of the power member 52 is connected to the turntable 51 to drive the turntable 51 to rotate. The first placement area and the second placement area are located on the turntable 51, and the two are symmetrically distributed about the rotation axis of the turntable 51.

[0082] Exemplarily, the power component 52 is a drive motor, or a combination of a drive motor and a transmission.

[0083] When taking or placing the collecting cylinder 1, keep it as far away from the working position as possible to prevent the operation process of the collecting cylinder 1 from being affected by the connecting channel 2 or the collecting cylinder 1 in the working position.

[0084] refer to Figure 5 and Figure 6 The turntable 51 is provided with a placement groove 511 adapted to the collection barrel 1. When the collection barrel 1 is placed on the turntable 51, it is located in the placement groove 511. On the one hand, the stability of the collection barrel 1 relative to the turntable 51 is improved to avoid the problem of the collection barrel 1 shaking or even tilting during the rotation of the turntable 51. On the other hand, it is more convenient to ensure the certainty of the position of the collection barrel 1 relative to the turntable 51. When placing the collection barrel 1, there is no need to determine the placement position by measurement or other means. After driving the collection barrel 1 to rotate to the working position, the transfer tube 22 and the cover plate 12 are aligned and connected more accurately, and the problem of deflection is not easy to occur.

[0085] Exemplarily, the turntable 51 is configured as a split structure, the turntable 51 includes two splits, the first placement area and the second placement area are located on the two splits respectively. Each split includes a fixed block 512 and two movable blocks 513, the fixed blocks 512 of the two splits are fixedly connected so that the two splits form a whole, of course, the two fixed blocks 512 can also be configured as an integral structure.

[0086] The movable block 513 is hinged to the fixed block 512, and a locking structure for locking the two movable blocks 513 is arranged between the two movable blocks 513; the placement groove 511 is divided into two parts of the same size, which are respectively located on the two movable blocks 513. When the two movable blocks 513 are spliced ​​and locked by the locking structure, a placement groove 511 corresponding to the collection tube 1 is formed.

[0087] In this way, the process of taking out the collecting tube 1 from the placement groove 511 is more convenient. There is no need to lift the collecting tube 1 upwards. It is only necessary to gradually move the collecting tube 1 horizontally to take it out while opening the two movable blocks 513, thereby improving the convenience of use.

[0088] Compared with the case where the placement groove 511 is a whole, the placement groove 511 is divided into two parts of the same size, and the two movable blocks 513 cooperate to form the placement groove 511 that limits the position of the collection tube 1. In this way, the size of the placement groove 511 can be set so that the two movable blocks 513 cooperate to clamp the placement groove 511 in the locked state, thereby further improving the stability of the placement groove 511 relative to the turntable 51.

[0089] In this case, a buffer structure, such as a rubber pad, can be fixed on the side wall of the placement groove 511, which plays a certain buffering role in the process of clamping the collecting tube 1. While ensuring the clamping of the collecting tube 1, it avoids the problem of excessive clamping force applied to the collecting tube 1 causing deformation or damage to the collecting tube 1.

[0090] The locking structure may adopt common lock buckles, latches and other mechanisms, and only needs to be able to lock and fix the two movable blocks 513 .

[0091] In addition, refer to Figure 1 The collecting device also includes an adsorption magnet 6, which is located at least on the lower side of the collecting barrel 1 at the working position; specifically, the adsorption magnet 6 is fixedly connected to the box body 3 and is located in the working area. When the turntable 51 drives the collecting barrel 1 to the working position, the adsorption magnet 6 adsorbs the dust in the collecting barrel 1, so that the dust is deposited at the bottom of the collecting barrel 1 more quickly.

[0092] It is more convenient to clean the dust in the collection tube 1 later. In addition, the time that the dust stays in the adsorption liquid in the upper part is shortened, and the dust in the adsorption liquid is deposited at the bottom at a faster speed, so that the ability to adsorb dust in the argon gas can be restored more quickly, making the dust collection effect better.

[0093] In other embodiments, an adsorption magnet 6 may also be provided at the pick-up and placement position, or the adsorption magnet 6 may be directly fixedly connected to the bottom of the turntable 51, both of which can achieve the purpose of faster deposition of dust in the collection barrel 1, thereby improving the dust collection efficiency and the efficiency of subsequent cleaning of the dust in the collection barrel 1.

[0094] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be included in the scope of the claims and specification of the present application.
