Description

Technical Field

[0001] This utility model belongs to the field of solid electrolyte analysis and detection technology, and specifically relates to a solid electrolyte sample digestion device. Background Technology

[0002] In the analysis and detection of solid electrolytes, sample digestion is one of the key steps. Currently, the commonly used digestion method is to dissolve the sample using perchloric acid-hydrochloric acid.

[0003] However, this method has many problems. On the one hand, the operation process is complicated and requires precise control of the amount of reagents and reaction conditions. On the other hand, the sample is prone to splashing during the high-temperature heating and melting process, which can not only lead to large deviations in experimental results, but also cause injury to the experimental personnel. In addition, perchloric acid is a strong oxidant with great danger. Strict adherence to safety operating procedures is required during its use, which increases the risk and cost of the experiment.

[0004] Therefore, it is necessary to provide a solid electrolyte sample digestion device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a solid electrolyte sample digestion device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A solid electrolyte sample digestion device, comprising:

[0008] The workbench has support plates fixedly installed on both sides of its bottom. An oven is fixedly installed on one side of the top of the workbench. An opening is provided on one side of the oven. Slide grooves are provided on the top and bottom of the inner wall of the oven. An adjusting screw is rotatably installed inside the slide groove. A drive mechanism is provided on the other side of the oven. An adjusting block is sleeved on the outer wall of the adjusting screw and is slidably installed on the slide groove. Connecting plates are fixedly installed on opposite sides of the two adjusting blocks.

[0009] Symmetrically distributed guide rods are fixedly installed on one side of the connecting plate, and one end of the guide rod passes through the oven and extends to the outside of the oven.

[0012] Preferably, the driving mechanism includes a fixed box, which is fixedly installed on the other side of the oven. A worm gear is rotatably installed inside the fixed box. One end of each of the two adjusting screws passes through the oven and extends into the interior of the fixed box. A worm wheel is fixedly installed on the outer wall of one end of each of the two adjusting screws, and the worm wheel meshes with the worm gear.

[0015] Preferably, the adjusting block has a threaded hole that matches the adjusting screw, and the adjusting block is threadedly connected to the adjusting screw through the threaded hole.

[0016] The beneficial effects of this utility model are as follows:

[0017] This invention utilizes a workbench, oven, fixed chamber, first servo motor, sealing plate, movable plate, second servo motor, placement slot, electric telescopic rod, tray, digestion vessel, feed end, guide rod, opening, connecting plate, adjusting block, slide groove, adjusting screw, worm gear, and worm wheel in a coordinated manner. The device only requires adding the sample and hydrochloric acid to the digestion vessel and then placing it in the oven for heating, avoiding complex operating procedures and effectively reducing the labor intensity of experimental personnel.

A digestion tank 14 is fixedly installed on the drive end of the second servo motor 9. A feed end 15 is provided on the top of the digestion tank 14, and a sealing cover is provided on the feed end 15.

[0032] A placement slot 10 is provided on the other side of the top of the workbench 1. A horizontal plate 3 is fixedly installed between the two support plates 2. An electric telescopic rod 11 corresponding to the position of the placement slot 10 is fixedly installed on the top of the horizontal plate 3. A tray 12 adapted to the placement slot 10 is fixedly installed at the drive end of the electric telescopic rod 11, which facilitates the placement of external volumetric flasks and also has the effect of adjusting the height of the volumetric flasks, so that the volumetric flasks can accurately collect solutions, improving the convenience of the entire operation process.

[0033] In one embodiment, the drive mechanism includes a fixed box 5, which is fixedly installed on the other side of the oven 4. A worm gear 22 is rotatably installed inside the fixed box 5. One end of each of the two adjusting screws 21 passes through the oven 4 and extends into the interior of the fixed box 5. A worm wheel 23 is fixedly installed on the outer wall of one end of each of the two adjusting screws 21, and the worm wheel 23 meshes with the worm gear 22. A first servo motor 6 is fixedly installed on the top of the fixed box 5, and the drive end of the first servo motor 6 passes through the fixed box 5 and extends into the interior of the fixed box 5, and is fixedly connected to the top end of the worm gear 22, thereby realizing the automatic removal and insertion of the digestion tank 14 on the oven 4.

[0034] In one preferred embodiment, a symmetrically distributed limiting block 13 is fixedly installed on one side of the outer surface of the digestion vessel 14, and an annular slide 24 is provided on the other side of the movable plate 8, and the annular slide 24 is slidably connected to the limiting block 13.

[0035] In one embodiment, the limiting block 13 is T-shaped and is adapted to the annular slide 24 to prevent the limiting block 13 from falling out of the annular slide 24 and to ensure the stability of the digestion tank 14 when it rotates.

[0036] In one preferred embodiment, the adjusting block 19 has a threaded hole that matches the adjusting screw 21, and the adjusting block 19 is threadedly connected to the adjusting screw 21 through the threaded hole.

[0037] The working principle of this utility model is as follows: All electrical components mentioned are electrically connected to the main controller and power supply. The main controller can be a computer or other conventionally known control device, and existing publicly available power connection technologies are not elaborated here. Parts not mentioned in this device are the same as or can be implemented using existing technologies. In use, the first servo motor 6 is first started, its drive end drives the worm gear 22 to rotate. Through the meshing transmission between the worm gear 22 and the worm wheel 23, the two worm wheels 23 rotate synchronously, thereby driving the adjusting screw 21 to rotate. Through the threaded transmission between the adjusting screw 21 and the adjusting block 19, and the sliding guide action of the adjusting block 19 within the slide groove 20, the two adjusting blocks 19 move laterally synchronously. The movement of the adjusting blocks 19 drives the connecting plate 18 to move, and the connecting plate 18 further drives the guide rod 16 to slide on the oven 4. Simultaneously, the movement of guide rod 16 causes sealing plate 7 to move, which in turn causes movable plate 8 to move. Movable plate 8, via second servo motor 9, drives digestion vessel 14 to move, causing it to move outward from workbench 1. At this point, movable plate 8 is no longer sealing opening 17, and digestion vessel 14 follows movable plate 8 through opening 17 out of oven 4. After digestion vessel 14 is removed, a precise amount of electrolyte sample is weighed and loaded into digestion vessel 14 through feed end 15, along with a precise amount of hydrochloric acid. The sealing cap on feed end 15 is then tightened to ensure a good seal. Subsequently, movable plate 8, containing the sample and reagents, is moved into oven 4 by first servo motor 6 and kept at a set constant temperature for a certain period to allow for complete digestion of the sample. After digestion, digestion vessel 14 is removed from oven 4 and allowed to cool naturally to room temperature. At the same time, a volumetric flask is placed on top of tray 12, and then second servo motor 9 is started, its drive end rotating digestion vessel 14 180 degrees so that feed end 15 faces downward. The electric telescopic rod 11 is then activated, its drive end moving the tray 12 vertically, raising the volumetric flask placed on the tray 12 to the feed end 15. The sealing cap of the feed end 15 is opened, and the solution in the digestion vessel 14 is transferred to the volumetric flask, diluted to volume, and shaken well. Finally, an atomic absorption spectrometer is used to test the diluted solution to analyze its elemental content. This device only requires adding the sample and hydrochloric acid to the digestion vessel 14 and then heating it in the oven 4, avoiding complex operating procedures and effectively reducing the labor intensity of experimental personnel. It eliminates the use of perchloric acid, removing the safety hazards associated with perchloric acid and improving experimental safety. Since hydrochloric acid is a common and relatively inexpensive reagent, using hydrochloric acid instead of perchloric acid reduces experimental costs. Using the digestion vessel 14, which only requires adding hydrochloric acid to dissolve electrolyte samples, avoids result deviations caused by sample splashing, ensuring that experimental results are basically consistent with standard values ​​and improving the accuracy of analysis and detection. In addition, the entire operation process is highly mechanized, significantly improving ease of use.

[0038] When the digestion vessel 14 is adjusted by driving it with the second servo motor 9, the rotation of the digestion vessel 14 causes the limiting block 13 to slide on the annular slide rail 24. Through the coordinated operation of the annular slide rail 24 and the worm gear 23, the stability of the digestion vessel 14 during operation is significantly enhanced. This design avoids concentrating the entire weight of the digestion vessel 14 on the drive end of the second servo motor 9, instead employing a multi-point force distribution method to effectively disperse the load generated by the digestion vessel 14, thereby reducing the workload of the second servo motor 9. By reducing the load on the second servo motor 9, the stability and reliability of the entire device operation are improved, reducing the risk of equipment failure and performance degradation due to excessive load.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
