Description

Technical Field

[0001] This utility model relates to the technical field of thermal digestion, and more specifically, to a crucible thermal digestion support device. Background Technology

[0002] Hot plate digestion is the most common wet digestion method, using strong acids such as hydrochloric acid, nitric acid, hydrofluoric acid, perchloric acid, and sulfuric acid to dissolve the sample at high temperatures, forming a clear solution suitable for instrument analysis. Compared to high-pressure sealed vessel digestion and microwave digestion, hot plate digestion has advantages such as simple operation, high efficiency, and low cost. Among various feasible digestion methods, most laboratories choose hot plate digestion as the preferred method.

[0003] The common procedure for thermal digestion involves placing the sample to be digested in a crucible (such as one made of polytetrafluoroethylene), then placing the crucible on a hot plate for heating and digestion. After a certain time, the crucible is removed for further processing. However, when dealing with a large number of samples, placing and removing each crucible individually is time-consuming. Furthermore, sample numbers may be misplaced during the process, and sufficient spacing must be maintained between crucibles to prevent uneven heating. Manual placement is also time-consuming and labor-intensive. Therefore, a device that allows for efficient sample placement and removal should be designed. Utility Model Content

[0004] The purpose of this invention is to provide a crucible thermal digestion support device that can efficiently place samples on a hot plate for thermal digestion while ensuring that crucibles do not come into contact with each other.

[0005] This utility model is achieved through the following technical solution: The crucible thermal digestion support device of this utility model includes a square base plate, a surrounding plate fixedly disposed on the edge of the base plate, a plurality of slots opened on the upper side of the surrounding plate, and a separating device disposed above the surrounding plate; the separating device includes a first separating rod and a second separating rod arranged horizontally and parallel to each other, and an adjusting device for adjusting the distance between the first separating rod and the second separating rod; the first separating rod and the second separating rod are both engaged in the slots.

[0006] Furthermore, slots are provided on all four sides of the upper side of the enclosure.

[0007] Furthermore, the slot is V-shaped.

[0008] Furthermore, both the first separating rod and the second separating rod have a spindle-shaped cross-section in the vertical direction.

[0009] Furthermore, the adjusting device includes a fixed block connected to the end of the first separating rod, a sliding rod connected to the fixed block, a slider connected to the end of the second separating rod, and a sliding hole formed in the slider; the length direction of the sliding rod is perpendicular to the length direction of the first separating rod; the sliding rod is slidably disposed in the sliding hole.

[0010] Furthermore, the adjusting device also includes a fastening bolt threadedly connected to the slider, the fastening bolt abutting against the slider rod.

[0011] Furthermore, a label plate is provided on the long outer wall of the enclosure, and the upper side of the label plate is hinged to the enclosure.

[0012] Furthermore, handles are fixedly provided on both outer side walls of the enclosure. Since the base plate may come into contact with strong acid, a polytetrafluoroethylene coating can be applied to the surfaces of the base plate, enclosure, and handles.

[0013] Furthermore, the base plate has multiple drainage holes.

[0014] The technical solution of this utility model has at least the following advantages and beneficial effects: In use, the crucible thermal digestion support device of this utility model first places all the crucibles on the base plate, arranging them roughly in a matrix. Then, the first and second separating rods are simultaneously engaged on both sides of the crucibles (each time, one row or column of crucibles is engaged between the first and second separating rods), and both the first and second separating rods are simultaneously engaged in the slots. This creates identical gaps between the crucibles. By sequentially creating identical gaps between all the crucibles on the base plate, adjacent crucibles will not contact each other, resulting in more consistent thermal digestion effects for each crucible and better overall thermal digestion. Furthermore, using a separating device to separate the crucibles is more efficient and effective than manual placement. Attached Figure Description

[0020] Example

[0021] The following description, in conjunction with specific embodiments, further illustrates the point, as shown in the appendix. Figure 1 - Appendix Figure 4 As shown, the crucible thermal digestion support device of this embodiment includes a square base plate 11, a surrounding plate 12 fixedly disposed on the edge of the base plate 11, a plurality of slots 13 opened on the upper side of the surrounding plate 12, and a separating device 20 disposed above the surrounding plate 12; the separating device 20 includes a first separating rod 21 and a second separating rod 22 arranged horizontally and parallel to each other, and an adjusting device for adjusting the distance between the first separating rod 21 and the second separating rod 22; the first separating rod 21 and the second separating rod 22 are both engaged in the slots 13. Specifically, during use, all crucibles 30 (containing the liquid sample to be thermally digested) are first placed on the base plate 11, arranged in a roughly matrix-like pattern. Then, the first separating rod 21 and the second separating rod 22 are simultaneously engaged on both sides of the crucibles 30 (each row or column of crucibles is engaged between the first separating rod 21 and the second separating rod 22), and both the first separating rod 21 and the second separating rod 22 are simultaneously engaged in the slots 13. This creates identical gaps between the crucibles 30. By sequentially creating identical gaps between all the crucibles 30 on the base plate 11, adjacent crucibles 30 will not contact each other, resulting in more consistent thermal digestion effects for each crucible 30 (and the sample inside), and ultimately, better overall thermal digestion. Furthermore, using a separation device to separate the crucibles 30 is more efficient and effective than manual placement. It should be noted that this device only serves to support the crucible 30. During thermal digestion, the bottom plate 11 and the crucible 30 on it need to be placed on the heating plate for heating.

[0022] In this embodiment, slots 13 are provided around the upper perimeter of the enclosure 12. The slots 13 are V-shaped. The cross-sections of the first separating rod 21 and the second separating rod 22 in the vertical direction are both spindle-shaped. Specifically, the V-shaped slots 13 cooperate with the spindle-shaped first separating rod 21 and the second separating rod 22, so that when the first separating rod 21 or the second separating rod 22 is inserted into the slots 13, the first separating rod 21 and the second separating rod 22 will not wobble significantly, and the first separating rod 21 and the second separating rod 22 can also be better inserted between the contacting crucibles 30.

[0023] The adjusting device in this embodiment includes a fixing block 23 connected to the end of the first separating rod 21, a sliding rod 24 connected to the fixing block 23, a slider 25 connected to the end of the second separating rod 22, and a sliding hole formed in the slider 25; the length direction of the sliding rod 24 is perpendicular to the length direction of the first separating rod 21; the sliding rod 24 is slidably disposed in the sliding hole. The adjusting device also includes a fastening bolt 26 threadedly connected to the slider 25, and the fastening bolt 26 abuts against the sliding rod 24. Specifically, for crucibles 30 of different sizes (mainly diameters), it is necessary to adjust the distance between the first separating rod 21 and the second separating rod 22. This can be achieved by sliding the slider 25 so that the slider 25 moves on the sliding rod 24, and tightening the fastening bolt 26 can fix the slider 25 and the sliding rod 24.

[0024] In this embodiment, a label plate 16 is provided on the long outer wall of the enclosure 12, and the upper side of the label plate 16 is hinged to the enclosure 12. Specifically, the corresponding crucible 30 number can be written on the label plate 16 to facilitate the classification of crucible 30. The label plate 16 is hinged to the enclosure 12, so that the label plate 16 can be directly flipped flat for easy viewing and writing.

[0025] In this embodiment, handles 14 are fixedly provided on both outer side walls of the enclosure 12. Specifically, the handles 14 are provided to facilitate manual movement by holding the handles 14.

[0026] In this embodiment, the base plate 11 has multiple drainage holes 15. Specifically, the crucible 30 can be cleaned and placed on the base plate 11 before being placed on the base plate 11. At this time, the water remaining on the crucible 30 can be drained through the drainage holes 15.

[0027] In summary, the crucible thermal digestion support device of this embodiment, during use, first places all the crucibles 30 on the base plate 11, so that the crucibles 30 are roughly arranged in a matrix. Then, the first separating rod 21 and the second separating rod 22 are simultaneously engaged on both sides of the crucibles 30 (each row or column of crucibles 30 is engaged between the first separating rod 21 and the second separating rod 22), and both the first separating rod 21 and the second separating rod 22 are simultaneously engaged in the slots 13. This can separate the crucibles 30 with the same gap. By sequentially separating all the crucibles 30 on the base plate 11 with the same gap, adjacent crucibles 30 will not come into contact, the thermal digestion effect of each crucible 30 will be more consistent, and the overall thermal digestion effect will be better. Furthermore, using a separation device to separate the crucibles 30 from each other is more efficient and effective than manual placement.

[0028] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
