[0030] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0032] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] Based on the description in the background technology, it can be known that the problems existing in the ash cleaning of the existing element analyzer include the inconvenience of disassembling the machine when replacing and taking the crucible, and all processes are manual, which is inefficient and wastes manpower. In addition, the existing element analyzer is also manual when moving the crucible from the feed tray 2 to the combustion mechanism 3, and there is also the above-mentioned low efficiency problem. Therefore, this embodiment adds an automatic crucible cleaning device to the existing element analyzer. The automatic crucible cleaning device is a part of the element analyzer, and the combustion mechanism 3 of the element analyzer can be used as a part of the automatic cleaning device. The automatic cleaning device clamps the crucible through mechanical automation, and drives the crucible to move in the material trough 21, the combustion position 23, the combustion mechanism 3, and the unloading position 24, so as to realize the automatic collection and cleaning of the crucible, so as to facilitate the subsequent replacement of the crucible.

[0034] Specifically, combined with Figure 1 and 2 As shown, the automatic crucible cleaning device of this embodiment includes a mounting mechanism 1, a feed tray 2, a combustion mechanism 3, a discharge mechanism 4 and a crucible moving mechanism 5, wherein the mounting mechanism 1 of this embodiment serves as the mounting base of the entire device, which can be connected and coordinated with other structures of the element analyzer.

[0035] The feed tray 2 of this embodiment is installed on the mounting mechanism 1. The feed tray 2 is provided with a plurality of material slots 21 for placing crucibles. Figure 5 As shown, preferably, in order to increase the number of crucibles that can be placed, the material troughs 21 of this embodiment are distributed in multiple rows along the radial direction of the feed tray 2, and each row of material troughs 21 is evenly spaced along the circumference of the feed tray 2. A combustion position 23 and a material discharge position 24 are provided on the feed tray 2. The material discharge position 24 is adjacent to or connected to the material discharge mechanism 4, and the combustion position 23 is adjacent to or connected to the combustion mechanism 3. In order to facilitate direct entry into the material discharge position 24 after the crucible is burned, the combustion position 23 and the material discharge position 24 are designed to be adjacent to each other in this embodiment.

[0036] The combustion mechanism 3 of this embodiment is located below the combustion position 23. The combustion mechanism 3 is provided with a combustion chamber 31. The combustion chamber 31 is used to accommodate the crucible from the combustion position 23, and the material in the crucible can be burned in the combustion chamber 31. Specifically, the combustion mechanism 3 of this embodiment can be the combustion tube shown in the figure, and the combustion chamber 31 is formed by the inner wall of the combustion tube.

[0037] The unloading mechanism 4 of this embodiment is located below the unloading position 24 and is used to receive the crucibles from the unloading position 24. The crucibles from the unloading position 24 are all crucibles after the material combustion is completed. The unloading mechanism 4 collects the crucibles in a unified manner for subsequent ash cleaning.

[0038] The crucible moving mechanism 5 of this embodiment is installed on the mounting mechanism 1, which serves as the core structure of the entire crucible automatic cleaning device. The crucible moving mechanism 5 is used to move the crucible on the material trough 21 to the combustion chamber 31 via the combustion position 23 to realize automatic loading of the crucible, and the crucible moving mechanism 5 of this embodiment is also used to move the crucible in the combustion chamber 31 to the unloading position 24 to complete the automatic cleaning of the crucible with ash.

[0039] Based on the above structural description, it can be known that the automatic crucible cleaning device provided in this embodiment can realize the picking up and moving of the crucible through the crucible moving mechanism 5, thereby realizing the automation of sampling; after the sample is made, the crucible that collects the ash is moved to the unloading mechanism 4 through the crucible moving mechanism 5 to facilitate the placement of a new crucible. There is no need to disassemble the machine to clean the ash in the crucible, which not only liberates manpower but also improves the ash cleaning efficiency.

[0040] Combined with Figure 3 , Figure 4 and Figure 5As shown, in order to reduce the size of the device and improve the compactness of the structure and to reasonably utilize the space, the present embodiment optimizes the installation position of the crucible moving mechanism 5. First, an opening 25 is provided in the middle of the feed tray 2. The size of the opening 25 is required to accommodate the lower structure of the crucible moving mechanism 5. The mounting mechanism 1 is located below the feed tray 2, and the crucible moving mechanism 5 is mounted on the mounting mechanism 1 via the opening 25. This mounting method enables the crucible moving mechanism 5 to be located in the middle of the feed tray 2, so that the crucible moving mechanism 5 can drive the crucible to move at various positions of the feed tray 2. Compared with placing the crucible moving mechanism 5 outside the feed tray 2, this design method can reduce the size of the entire device and shorten the moving stroke required for the crucible moving mechanism 5.

[0041] Combined with Figure 2 , Figure 3 and Figure 4 As shown, the crucible moving mechanism 5 of this embodiment includes a driving assembly 51 and a crucible clamp 52; wherein, the driving assembly 51 of this embodiment can be installed on the mounting mechanism 1 through the opening 25 of the above-mentioned feed tray 2, and the driving assembly 51 is connected to the crucible clamp 52. The driving assembly 51 can be used to drive the crucible clamp 52 to rise and fall, and to drive the crucible clamp 52 to move circumferentially and radially along the feed tray 2.

[0042] In order to realize that the driving component 51 of this embodiment can drive the crucible clamp 52 to rise and fall, and move circumferentially and radially on the feed tray 2, the driving component 51 of this embodiment is designed to include a rotating driving component 511, a translation component 512 and a lifting component 513 connected in sequence; wherein, the rotating driving component 511 of this embodiment is installed on the mounting mechanism 1, and is used to drive the translation component 512 to rotate, and the rotating driving component 511 can be any component that can output torque, such as a motor.

[0043] The translation component 512 of this embodiment is connected to the lifting component 513, and is used to drive the lifting component 513 to move horizontally along the radial direction of the feed tray 2. The translation component 512 of this embodiment may include a slide seat 5121 and a slide table 5122. The slide table 5122 can reciprocate horizontally on the slide seat 5121. The horizontal reciprocating motion can be achieved by any existing linear reciprocating motion structure (such as a pneumatic rod, an electric rod, etc.).

[0044] The bottom end of the lifting component 513 of this embodiment is connected to the crucible clamp 52 and is used to drive the crucible clamp 52 to rise and fall. The crucible clamp 52 of this embodiment can be the clamping claw structure shown in the figure, or it can be any existing structure with a clamping function, which will not be described in detail in this embodiment.

[0045] Since the feed tray 2 of the present embodiment is covered with material troughs 21, and the crucible clamp 52 needs to be protected to a certain extent when the device is not working, the feed tray 2 of the present embodiment is provided with an initial position 22, and the initial position 22 is provided with a first through hole 221. When the device is shut down, the crucible clamp 52 of the present embodiment can be placed in the first through hole 221. When the crucible needs to be moved, the crucible clamp 52 moves from the initial position 22 to a position 11 mm above the crucible of the material to be burned to pick up the crucible, thereby completing subsequent combustion and unloading.

[0046] Based on the above structure, in order to facilitate the crucible to move from the combustion position 23 to the combustion chamber 31, the combustion position 23 of this embodiment is provided with a second through hole (not shown in the figure) connected to the combustion chamber 31, and the crucible clamp 52 can be inserted into the combustion mechanism 3 through the second through hole and seal the second through hole. Specifically, the crucible clamp 52 can be sealed with the second through hole through structures such as a sealing ring 521, and the top end of the combustion mechanism 3 of this embodiment is connected to the feed tray 2 through structures such as a first flange 32 and a second flange 33, thereby realizing a sealed connection between the combustion chamber 31 and the feed tray 2 to ensure the accuracy of subsequent measurements.

[0047] Similarly, in order to facilitate unloading, the unloading position 24 of the present embodiment is provided with a third through hole 241 connected to the unloading mechanism 4, and the unloading mechanism 4 is connected to the third through hole 241. Specifically, the unloading mechanism 4 of the present embodiment includes a unloading pipe 41 and a crucible collection box 42; one end of the unloading pipe 41 is connected to the third through hole, and the other end is connected to the crucible collection box 42. Of course, the structural form of the unloading mechanism 4 of the present embodiment is not limited to this, and any structure that can unload and collect crucibles can be used as the unloading mechanism 4 of the present embodiment, such as a landslide unloading structure.

[0048] Based on the structure of the driving assembly 51 described above, the present embodiment makes improvements to the mounting mechanism 1, which includes a mounting plate 11 and a mounting bracket 12; the feed tray 2 is mounted on the upper surface of the mounting plate 11, and the mounting bracket 12 is mounted on the lower surface of the mounting plate 11; the mounting bracket 12 is similar to a U-shape, and a supporting portion is formed at its bottom and is located below the opening 25, and the supporting portion has a preset distance from the opening 25, and the rotating driving component 511 of the crucible moving mechanism 5 is mounted on the supporting portion, and the rotating driving component 511 is located below the opening 25 to reduce the height of the entire crucible moving mechanism 5 and reduce the required lifting stroke.

[0049] In addition, in order to protect the lifting component 513 of the driving assembly 51 of this embodiment, this embodiment also has a protective shell 6 disposed outside the lifting component 513, and is also provided with a high-temperature heat shield 7, which is installed at the lower part of the protective shell 6 through screws and other connectors to prevent the heat generated during the combustion process from affecting the performance of the driving assembly 51. In addition, in order to protect the crucible on the feed tray 2, this embodiment has a protective plate 8 above the feed tray 2, which is arranged on the feed tray 2 in parallel and has a preset interval with the feed tray 2, and the protective plate 8 is provided with a notch, and is installed on the translation component 512 of this embodiment through the notch.

[0050] Based on the above structure, this embodiment also provides an element analyzer, including an automatic crucible cleaning device as in the above technical solution. Since the improvement of the element analyzer in this embodiment lies only in the automatic crucible cleaning device, this embodiment does not provide illustrations and principle descriptions of other structures of the element analyzer.

[0051] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention 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 with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
