Description

Technical Field

[0001] This utility model relates to the field of gold alum raw material dissolution technology, specifically to a gold alum testing raw material dissolution device. Background Technology

[0002] In the process of dissolving raw materials for alum analysis, conical dissolving flasks are often used as reaction vessels. Their geometric structure, which is narrow at the top and wide at the bottom, can effectively reduce liquid splashing, facilitate shaking and mixing, and control the uniformity of heating. They are also suitable for subsequent operations such as titration and volume determination. Existing alum dissolving equipment is usually equipped with a magnetic stirrer to accelerate dissolution. However, the fixation of conical flasks often relies on traditional clamps or manual support. When dealing with conical flasks of different taper and specifications, frequent adjustments are required. There is room for improvement in terms of ease of operation and fixation stability.

[0003] In practice, the traditional fixing method results in uneven contact pressure distribution at the conical bottleneck, which may damage the glass container or cause it to be unstable. In particular, it is prone to shaking during high-speed stirring, which affects the dissolution efficiency and experimental safety. Utility Model Content

[0004] The purpose of this invention is to provide a raw material dissolution device for alum analysis, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a raw material dissolving device for alum analysis, comprising a magnetic stirrer, wherein a dissolving bottle limiting component is provided on one side of the magnetic stirrer;

[0006] The limiting component includes a guide rod fixedly connected to one side of the magnetic stirrer. A threaded rod is fixedly connected to the upper end of the guide rod. A threaded sleeve is threaded on the outer wall of the threaded rod. A compression ring is rotatably connected to the lower end of the threaded sleeve. A resistance spring is fixedly connected to the lower end of the compression ring. A slider is fixedly connected to the lower end of the resistance spring. A bracket is fixedly connected to one side of the slider. A limiting ring is fixedly connected to one side of the bracket.

[0007] Preferably, a reinforcing rib is fixedly connected between the compression ring and the bracket, and the reinforcing rib is 1 / 3 of the thickness of the bracket.

[0008] Preferably, the inner side of the limiting ring is designed with an inclined structure.

[0009] Preferably, a plurality of arrayed strip blocks are fixedly connected to the inner side of the limiting ring, and the inclination angle of the strip blocks is consistent with that of the inner side of the limiting ring.

[0010] Preferably, the lower end of the limiting ring is fixedly connected to an array of limiting frames, and the limiting frames are tilted at the same angle as the inner side of the limiting ring.

[0011] Compared with the prior art, the advantages of this utility model are: the rotating threaded sleeve can elastically clamp conical bottles of different heights and diameters; the design of the resistance spring ensures uniform contact pressure and avoids damage to the bottle body by rigid compression; in addition, the inclined structure on the inner side of the limiting ring is adapted to the taper of the conical bottle, and the strip block reduces the friction contact area, improves the fixing stability, and reduces the contact area between the limiting ring and the conical bottle, which facilitates subsequent disassembly. The structure is simple and easy to use. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 The present invention provides the following technical solution:

[0019] Example 1: A raw material dissolving device for alum analysis, including a magnetic stirrer 1, a dissolving bottle limiting component is provided on one side of the magnetic stirrer 1; the limiting component includes a guide rod 2 fixedly connected to one side of the magnetic stirrer 1, a threaded rod 3 fixedly connected to the upper end of the guide rod 2, a threaded sleeve 4 threadedly fitted on the outer wall of the threaded rod 3, a compression ring 5 rotatably connected to the lower end of the threaded sleeve 4, a resistance spring 6 fixedly connected to the lower end of the compression ring 5, a slider 7 fixedly connected to the lower end of the resistance spring 6, a bracket 8 fixedly connected to one side of the slider 7, and a limiting ring 9 fixedly connected to one side of the bracket 8;

[0020] In use, place the dissolving bottle containing alum raw material and solvent on the upper end of the magnetic stirrer 1, so that the bottle body is in the center position of the quasi-limiting ring 9. Rotate the threaded sleeve 4. Since the threaded sleeve 4 is threadedly engaged with the threaded rod 3, the threaded sleeve 4 moves downward along the threaded rod 3, driving the compression ring 5 to move downward. The moving compression ring 5 drives the resistance spring 6 to move downward. The resistance spring 6 then drives the slider 7 to move. The slider 7 then slides downward along the guide rod 2 and moves towards the dissolving bottle through the bracket 8 and the limiting ring 9. When the limiting ring 9 contacts the body of the dissolving bottle, continue to rotate the threaded sleeve 4. The resistance spring 6 is further compressed and generates elastic force, so that the limiting ring 9 fits tightly against the body of the dissolving bottle, achieving clamping and fixing of the dissolving bottle. At this time, put the stir bar into the bottle and turn on the magnetic stirrer 1. The stir bar rotates and drives the solution to stir, so that the alum raw material dissolves faster.

[0021] Example 2: This example differs from Example 1 in that: a reinforcing rib 10 is fixedly connected between the extrusion ring 5 and the support 8, the reinforcing rib 10 being 1 / 3 the thickness of the support 8; the inner side of the limiting ring 9 has an inclined structure design; several arrayed strip blocks 11 are fixedly connected to the inner side of the limiting ring 9, the inclination angle of the strip blocks 11 being consistent with that of the inner side of the limiting ring 9; and an arrayed limiting frame 12 is fixedly connected to the lower end of the limiting ring 9, the inclination angle of the limiting frame 12 being consistent with that of the inner side of the limiting ring 9.

[0022] When in use, the conical dissolving bottle is placed on top of the magnetic stirrer 1 with the bottle body aligned with the center of the limiting ring 9. Since the inner side of the limiting ring 9 has an inclined structure, it can be adapted to the taper of the conical bottle body. The reinforcing rib 10 between the extrusion ring 5 and the support 8 enhances the connection strength between the extrusion ring 5 and the support 8, preventing the support 8 from deforming under force and ensuring the stability of the limiting component. The strip block 11 on the inner side of the limiting ring 9 has the same inclination angle as the inner side of the limiting ring 9, reducing the contact area and friction between the limiting ring 9 and the conical bottle body, preventing the dissolving bottle from being lifted and tipping over due to friction when the limiting ring 9 rises. The limiting frame 12 at the lower end of the limiting ring 9 has the same inclination angle as the inner side of the limiting ring 9. When clamping the conical bottle, the limiting frame 12 contacts the lower part of the conical bottle body, providing additional support and further improving the stability of the dissolving bottle. Especially when the magnetic stirrer 1 is stirring at high speed, it can effectively suppress the shaking of the dissolving bottle.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
