Description

Technical Field

[0001] The utility model relates to a fast dissolving instrument, in particular to a fast dissolving instrument for chemical analysis. Background Art

[0002] In the field of chemical analysis, high standards are often placed on the dissolution and mixing of substances. Previous dissolution equipment had many shortcomings. For example, the dissolution container was often fixed in a single direction, which made it easy for the container to move or tip over during the mixing process, affecting the accuracy and safety of the experiment.

[0003] Moreover, the traditional stirring device has a poor fixing effect on the container, making it difficult to ensure the stability of the container during high-speed stirring, which can easily cause solution leakage or uneven stirring.

[0004] In addition, in terms of operation and control, the previous equipment was not convenient and flexible enough to achieve precise control of the stirring process, thus failing to efficiently achieve the purpose of rapid sample preparation, which seriously affected the efficiency and quality of chemical analysis.

[0005] Based on these problems, the present technical solution came into being, aiming to solve the above shortcomings and provide a more stable, convenient and efficient rapid dissolution instrument for chemical analysis. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the defects of the above-mentioned technologies and provide a rapid dissolution instrument for chemical analysis.

[0007] In order to solve the above technical problems, the technical solution provided by the present invention is a rapid dissolution instrument for chemical analysis: comprising a bottom support frame; a placement tray is fixedly provided in the middle of the upper side of the bottom support frame;

[0008] The placing tray is symmetrically provided with vertical limit blocks, the number of the vertical limit blocks is two and they are symmetrically arranged, an internal threaded sleeve is fixedly provided on the placing tray, the internal threaded sleeve and the two vertical limit blocks form an equilateral triangle, the internal threaded sleeve is provided with a handle bolt, and the handle bolt and the internal threaded sleeve are threadedly engaged; a dissolving cup containing a substance to be dissolved is placed on the placing tray, and the dissolving cup containing the substance to be dissolved is supported by the two vertical limit blocks and the end of the handle bolt stud portion, so that the dissolving cup containing the substance to be dissolved is fixed;

[0009] A supporting column is fixedly provided on the outer side of the bottom supporting frame, a rope is provided at the end of the supporting column, and an electric stirrer mechanism is provided at the end of the rope.

[0010] As an improvement, the projection of the placement tray in the top view is circular.

[0011] As an improvement, the electric agitator mechanism includes an electric agitator body, the lower part of the electric agitator body is provided with an annular plate body with an L-shaped cross-section, the interior of the annular plate body is provided with a rubber friction ring body with an L-shaped cross-section, the upper side of the annular plate body is fixedly connected to the lower part of the electric agitator body, the outer edge of the lower part of the annular plate body is provided with an elastic metal sheet, the rear part of the elastic metal sheet protrudes outward, and the inner side of the lowest part of the elastic metal sheet is provided with a friction block, the pressing ring body and the outer side of the annular plate body are matched by a threaded connection, the lower side of the pressing ring body is provided with a slope, and the slope of the lower side of the pressing ring body body presses against the protruding part of the rear part of the elastic metal sheet.

[0012] As an improvement, a pressing ring member is provided on the outside of the L-shaped rubber friction ring.

During operation, the friction block, located on the inner side of the lower portion of the flexible metal sheet, firmly presses against the upper portion of the dissolution cup. This ensures the stability of the dissolution cup even under high-speed stirring, generating significant centrifugal forces. This prevents experimental errors and safety hazards that could arise from container sway. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Structure Description:

[0036] At the very bottom of the instrument is the bottom support frame 1, which provides overall support. A circular, top-view placement tray 2 is fixed to the center of the upper side of the bottom support frame 1. Two vertical stoppers 3 are symmetrically positioned on this tray 2, providing initial positioning of the dissolution cup from both sides. Furthermore, an internally threaded sleeve 4 is fixed to the tray 2, onto which a handle bolt 5 is mounted. The sleeve 4 and the two vertical stoppers 3 form an equilateral triangle to more securely hold the dissolution cup.

[0037] A support column 6 is fixedly provided on the outer side of the bottom support frame 1 , and the end of the support column 6 is connected to the electric stirrer mechanism through a rope 7 .

[0038] The core of the electric stirrer mechanism is the electric stirrer body 8, the lower part of which is provided with an annular plate body 9 with an L-shaped cross-section. Inside the annular plate body 9 is provided a rubber friction ring body 10 with the same L-shaped cross-section, which is used to enhance the contact sealing and friction with the opening of the dissolution cup. An elastic metal sheet 11 is provided on the lower outer edge of the annular plate body 9. The rear part of the elastic metal sheet 11 protrudes outward, and a friction block 12 is provided on the inner side of the lowermost part. A pressing ring body part 13 is provided on the outside of the L-shaped rubber friction ring body 10. The pressing ring body part 13 is connected to the outer side of the annular plate body 9 by a thread. The lower side of the pressing ring body part 13 is provided with a slope part 14 for squeezing the elastic metal sheet 11. The outer side of the pressing ring body part 13 is provided with evenly distributed friction lines 15 to facilitate operation and rotation.

[0039] A control panel 16 is provided on the electric stirrer body 8 for controlling the stirring operation. A stirring rod 17 is provided on the lower side of the electric stirrer body 8, and a stirring blade 18 is installed on the stirring rod 17 for stirring and dissolving the material in the dissolving cup.

[0040] Description of usage:

[0041] Step 1: Preparation

[0042] First put the substance to be dissolved into the dissolution cup.

[0043] Step 2: Fix the dissolution cup

[0044] Place the dissolution cup containing the substance on the placement tray 2 in the middle of the upper side of the bottom support frame 1. Next, rotate the handle bolt 5 on the internally threaded sleeve 4 so that the end of the stud rests against the dissolution cup. Together with the two vertical stoppers 3 symmetrically arranged on the placement tray 2, force is applied from different directions to firmly fix the dissolution cup, ensuring that the dissolution cup does not move or fall during the stirring process.

[0045] Step 3: Install the electric stirrer mechanism

[0046] The staff member picks up the electric stirrer mechanism and accurately places its L-shaped annular plate 9 over the opening of the dissolution cup. Carefully confirm that the L-shaped rubber friction ring 10 inside the annular plate 9 fits snugly against the opening of the dissolution cup. At this point, the stirring rod 17 and its attached stirring blades 18 should be completely inside the dissolution cup.

[0047] Step 4: Further fix the dissolution cup

[0048] The staff member rotates the pressing ring 13, causing the slope 14 on its lower side to contact the outward-protruding portion of the rear portion of the elastic metal sheet 11. The pressing ring 13 is then continuously rotated, causing the slope 14 to move downward, continuously pressing the rear portion of the elastic metal sheet 11. This operation causes the elastic metal sheet 11 to deform, bending its lower portion inward. This allows the friction block 12 located on the inner side of the lowest portion of the elastic metal sheet 11 to tightly press against the upper portion of the dissolving cup, further securing the cup and ensuring its stability during stirring.

[0049] Step 5: Start stirring

[0050] The user controls the operation of the device through the control panel 16 on the electric stirrer body 8. After starting, the stirring rod 17 and the stirring blade 18 start to run at high speed, stirring and mixing the materials in the dissolving cup quickly and stably, ultimately achieving the purpose of rapid sample preparation.

[0051] In terms of fixing the dissolution cup, this technical solution adopts a unique and efficient design. By rotating the handle bolt 5 on the internal threaded sleeve 4, the end of the stud portion can accurately support the dissolution cup. At the same time, the two vertical limit blocks 3 symmetrically arranged on the placement plate 2 also play a key role. These three fixed points apply force from different directions to form a stable clamping structure, which firmly fixes the dissolution cup in all directions. This multi-directional fixing method greatly improves stability. During the stirring process, no matter what kind of external impact or vibration it is subjected to, the dissolution cup will not move or tip over, providing a solid guarantee for the smooth progress of the experiment.

[0052] To further enhance the securement of the dissolution cup, this solution also cleverly incorporates the design of an elastic metal sheet 11 and friction block 12. During operation, the friction block 12, located on the inner side of the lowermost portion of the elastic metal sheet 11, tightly compresses the upper portion of the dissolution cup. This design not only increases the number of points of support for securement but also utilizes the elasticity of the elastic metal sheet and the friction of the friction block to effectively disperse the pressure during securement, further enhancing securement reliability. Even under high-speed stirring, which generates significant centrifugal forces, the stability of the dissolution cup is maintained during stirring, avoiding experimental errors or safety hazards that could be caused by container sway.

[0053] Finally, in terms of operation control, this technical solution fully considers the convenience and accuracy requirements of users. The user can easily control the operation of the equipment through the control panel 16 on the electric stirrer body 8. After startup, the stirring rod 17 and the stirring blade 18 will quickly start to run at high speed. This high-speed operation can quickly and stably stir and mix the materials in the dissolution cup, greatly improving the stirring efficiency and mixing effect, and ultimately smoothly achieving the purpose of rapid sample preparation. The entire operation process is simple and intuitive, easy to master, and at the same time can achieve precise control of the stirring process, meeting the high standards for dissolution and sample preparation in chemical analysis.

[0054] The above description of the present invention and its embodiments is non-limiting. The drawings show only one embodiment of the present invention, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by the above, and does not deviate from the purpose of the present invention, without inventive design, a structure and embodiment similar to the technical solution should fall within the scope of protection of the present invention.
