Description

Technical Field

[0001] This utility model belongs to the field of metal detection technology, and in particular relates to a rapid dissolution device for metal powder used in metal analysis. Background Technology

[0002] Metal analysis involves qualitative and quantitative compositional analysis of metals and their alloys using various methods to ensure their quality, composition, purity, and performance. This is crucial for the production, processing, use, and quality control of metals. Chemical analysis (wet analysis), as one of the main methods of metal analysis, separates precious metals from samples through chemical reactions. This method is applicable to various precious metals. In practice, powdered samples and dissolving solutions are placed separately into experimental containers for dissolution. However, in actual operation, the dissolution effect is poor when dissolving powders with larger particle sizes, and the dissolution rate is affected by the ambient temperature. Furthermore, the dissolving solution is hazardous, and the spillage of experimental containers can easily create safety hazards.

[0003] To address these issues, we provide a rapid dissolution apparatus for metal powders used in metal analysis. Utility Model Content

[0004] The purpose of this invention is to provide a rapid dissolution device for metal powders used in metal analysis. It uses an elastic element to compress a grinding plate, and the rotation of the grinding plate further grinds the metal powder to improve the dissolution effect. It also uses a heating wire to increase the dissolution temperature and a moving rod to expand the support area. This invention solves the problems of poor dissolution effect when dissolving powders with large particle sizes in the prior art, the influence of ambient temperature on the dissolution speed during the dissolution process, and the safety hazards caused by the tipping of experimental containers.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a metal powder rapid dissolution device for metal analysis, including a shell, a cup body fixed inside the shell, a grinding plate inside the cup body, a frosted layer on the lower wall of the grinding plate, a connecting rod fixed at the middle position of the upper wall of the grinding plate, a connecting sleeve with clearance fit on the outside of the connecting rod, and an elastic element on the outside of the connecting sleeve.

[0007] A heating wire is provided between the bottom of the outer shell and the cup body. A bottom shell is fixed to the lower wall of the outer shell. A mounting sleeve is fixed to the lower wall of the bottom shell in a circumferential array. A moving rod is provided in the internal clearance fit of the mounting sleeve.

[0008] The present invention is further configured such that a cup lid is threadedly connected to the upper part of the outer shell corresponding to the external thread of the cup body, the outer peripheral wall of the cup lid is provided with anti-slip ridges, and a sealing gasket is provided along the edge of the inner upper wall of the cup lid.

[0009] The present invention is further configured such that a rotating rod is rotatably connected to the middle position of the cup lid via a bearing, a horizontal plate is fixed to the upper end of the rotating rod, and a rocker arm is fixed to the outer end of the upper wall of the horizontal plate.

[0010] The present invention is further configured such that a circular plate is fixed at the lower end of the rotating rod, and the connecting sleeve is fixedly connected to the circular plate, and the upper and lower ends of the elastic member abut against the corresponding circular plate and the grinding plate, respectively.

[0011] The present invention is further configured such that a rectangular groove is provided on the peripheral wall of one side of the connecting sleeve, and a protrusion is fixed on the connecting rod corresponding to the inside of the rectangular groove.

[0012] The present invention is further configured such that a transparent viewing window is axially fixed to the peripheral wall of the outer shell corresponding to the location of the cup body, and a handle is fixed to the outer wall of the outer shell.

[0013] The present invention is further configured such that an insulation layer is fixed to the inner wall of the outer shell, a button is fixed to the peripheral wall of the bottom shell, and a battery is fixed to the lower wall inside the bottom shell.

[0014] The present invention is further configured such that a movable groove is provided on the side wall of the mounting sleeve, a boss is fixed on the movable rod corresponding to the inside of the movable groove, and a leveling pad is fixed on the outer end of the lower wall of the movable rod.

[0015] This utility model has the following beneficial effects:

[0016] This invention incorporates an elastic element and a grinding plate. The elastic element applies a force to the grinding plate towards the bottom of the cup. When the grinding plate rotates, the powder sample between the grinding plate and the bottom wall of the cup is further ground by the abrasive action of the lower wall of the grinding plate, thereby further reducing the particle size of the sample and improving the dissolution effect. This solves the problem of poor dissolution effect when dissolving powders with larger particle sizes in the prior art.

[0017] This invention, by incorporating a heating wire, a mounting sleeve, and a movable rod, generates heat through the heating wire, which acts on the sample and dissolving solution inside the container, raising their temperature and increasing their dissolving activity. This ensures optimal dissolving activity even at low ambient temperatures. Furthermore, by extending the movable rod beyond the mounting sleeve, the support area of ​​the metal powder rapid dissolving device for metal analysis and the placement platform is increased, reducing the likelihood of tipping and minimizing safety hazards. This invention solves the problems of dissolving speed being affected by ambient temperature and the safety risks associated with tipping over experimental containers.

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 skilled in the art without creative effort are within the protection scope of the present utility model. Example 1

[0028] Please see Figure 1-4 This utility model is a metal powder rapid dissolution device for metal analysis, including a shell 3, which can be made of a heat-insulating material with certain functions. A cup body 10 is fixed inside the shell 3. The cup body 10 is made of transparent material. A grinding plate 701 is provided inside the cup body 10. A frosted layer is provided on the lower wall of the grinding plate 701. When the grinding plate 701 rotates, it is used to further grind the powder sample under the action of the frosted layer. A connecting rod 7 is fixed at the middle position of the upper wall of the grinding plate 701. A connecting sleeve 6 is provided with a gap fit on the outside of the connecting rod 7. An elastic element 601 is provided on the outside of the connecting sleeve 6 to apply force to the grinding plate 701 so as to grind the sample with the cooperation of the cup body 10.

[0029] Specifically, a cup lid 1 is connected to the upper part of the outer shell 3 corresponding to the external thread of the cup body 10. The outer peripheral wall of the cup lid 1 is provided with anti-slip ridges 102 to increase the friction when rotating the cup lid 1. A sealing gasket 101 is provided at the edge of the inner upper wall of the cup lid 1 for sealing between the cup lid 1 and the cup body 10 to prevent the solution from splashing out during operation. The sealing gasket 101 can be fixed to the cup lid 1 by adhesive. At the same time, a vent hole is also provided on the cup lid 1.

[0030] A rotating rod 2 is rotatably connected to the middle position of the cup lid 1 via a bearing. A horizontal plate 201 is fixed to the upper end of the rotating rod 2. A rocker arm 201a is fixed to the outer end of the upper wall of the horizontal plate 201. By operating the rocker arm 201a to rotate, the horizontal plate 201 rotates, which in turn drives the rotating rod 2 to rotate.

[0031] The lower end of the rotating rod 2 is fixed with a circular plate 202, and the connecting sleeve 6 is fixedly connected to the circular plate 202. The upper and lower ends of the elastic element 601 abut against the corresponding circular plate 202 and grinding plate 701 respectively. When the rotating rod 2 rotates, it drives the circular plate 202 to rotate, thereby realizing the rotation of the connecting sleeve 6.

[0032] A rectangular groove 602 is provided on the peripheral wall of one side of the connecting sleeve 6. A protrusion 702 is fixed on the corresponding connecting rod 7 inside the rectangular groove 602. Through the cooperation of the rectangular groove 602 and the protrusion 702, the connecting sleeve 6 and the connecting rod 7 can move relative to each other. Under the action of the elastic element 601, the grinding plate 701 applies a suitable force to the sample and prevents the connecting sleeve 6 and the connecting rod 7 from separating.

[0033] A transparent window 303 is axially fixed on the peripheral wall of the outer shell 3 at the location of the cup body 10, so as to facilitate viewing the inside of the cup body 10. A handle 301 is fixed on the outer wall of the outer shell 3, and the sample grinding operation can be performed by holding the handle 301.

[0034] The operation process of this embodiment is as follows: the outer peripheral wall of the cup lid 1 is operated to rotate the cup lid 1, so that the cup lid 1 is disengaged from the cup body 10 by the threaded connection and the cup lid 1 is removed. At this time, the grinding plate 701 moves synchronously to the outside of the cup body 10, and an appropriate amount of sample is placed into the cup body 10. Then the cup lid 1 is operated to connect with the cup body 10 by the thread. Then the rocker arm 201a rotates the horizontal plate 201, which drives the rotating rod 2, the circular plate 202, the connecting sleeve 6, the connecting rod 7 and the grinding plate 701 to rotate. In this state, the grinding plate 701 further grinds the sample. Example 2

[0035] Please see Figure 1 , 2 3 and 5 are the second embodiment of this utility model. This embodiment is based on the previous embodiment, but differs from the first embodiment in that: a heating wire 9 is provided between the bottom of the outer shell 3 and the cup body 10. The heating wire 9 is electrically connected to the button 401 through a conductive wire, and the button 401 is electrically connected to the battery 402 through a conductive wire. The operation of the heating wire 9 can raise the cup body 10 to a suitable temperature to promote the dissolution reaction. The heating wire 9 is existing technology, and its model is not limited here. A bottom shell 4 is fixed to the lower wall of the outer shell 3. A mounting sleeve 8 is fixed to the lower wall of the bottom shell 4 in a circumferential array. The cross-section of the mounting sleeve 8 is set in a U-shape. A moving rod 5 is provided in the internal gap of the mounting sleeve 8. The moving rod 5 is moved outward to make the leveling pad 501 contact the placement platform, which can increase the support area and improve the stability during use.

[0036] Specifically, an insulation layer 302 is fixed to the inner wall of the outer shell 3 to reduce heat loss, a button 401 is fixed to the peripheral wall of the bottom shell 4 to control the operation of the heating wire 9, and a battery 402 is fixed to the lower wall inside the bottom shell 4 to power the heating wire 9.

[0037] The side wall of the mounting sleeve 8 is provided with a movable groove 801. Inside the movable groove 801, a boss 502 is fixed on the corresponding movable rod 5. The cooperation between the movable groove 801 and the boss 502 allows the movable rod 5 to move relative to the mounting sleeve 8 for unfolding and storage. When unfolded, the support area is increased. A leveling pad 501 is fixed to the outer end of the lower wall of the movable rod 5. The leveling pad 501 is made of anti-slip material. At the same time, the lower wall of the leveling pad 501 is lower than the lower wall of the mounting sleeve 8 so that the leveling pad 501 can contact the placement platform.

[0038] The remaining structure is the same as in Example 1;

[0039] The operation process of this embodiment is as follows: When in use, pull the moving rod 5 outward and place the metal powder rapid dissolution device for metal analysis on the placement platform. At this time, operate the cup lid 1 to perform the sample grinding operation. After the grinding operation, pour the dissolving liquid into the cup body 10 and turn on the power of the heating wire 9 by operating the button 401 to perform the sample rapid dissolution operation.
