Description

Technical Field

[0001] This utility model relates to the field of experimental equipment technology, and in particular to a manual crushing and stirring device for rapidly dissolving clumped chemicals. Background Technology

[0002] In laboratories, pharmaceutical factories, hospital preparation departments, and the research and quality control processes of SAP (superabsorbent polymer) resins, large quantities of physiological saline and other salt solutions are frequently prepared. These solutions typically use analytical grade sodium chloride as a raw material; however, due to its hygroscopic nature and tendency to clump, especially in high-humidity environments, bottled sodium chloride often forms hard lumps, posing numerous challenges for large-scale solution preparation. Currently, the difficulties are even more pronounced when dissolving large quantities of agglomerated sodium chloride in large dispensing tanks: 1. The clumps are large in volume and hard, making them difficult to break with ordinary glass rods or stirring paddles, resulting in laborious and inefficient operation and easy damage to the equipment; 2. When operators extend their arms into the container, it is not only inconvenient to exert force, but also easy to introduce external contaminants. At the same time, the limited length of the extension affects the purity of the final solution, which does not meet the cleanliness requirements of SAP laboratories. 3. The bottom of large mixing tanks is prone to forming dead zones for stirring, and the clumps and precipitates are difficult to dissolve completely, resulting in low dissolution efficiency and affecting the consistency and preparation efficiency of SAP-related experimental solutions.

[0003] Therefore, there is an urgent need for a special tool designed for large-diameter liquid preparation containers that can simultaneously break up clumps and achieve efficient mixing, in order to meet the SAP field's practical needs for clean, rapid, and uniform preparation of large batches of salt solutions.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0022] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0023] This invention provides a manual crushing and stirring device for rapidly dissolving clumped chemicals. It includes an operating handle 1, a rod 2, a crushing and stirring head 3, and a support 4. The rod 2 passes through the support 4 and is rotatable relative to the support 4. The lower end of the rod 2 is connected to the crushing and stirring head 3, and the upper end is connected to the operating handle 1. The support 4 spans across the port of a container, and the crushing and stirring head 3 is located inside the container. Under external force, the crushing and stirring head 3 can perform downward and rotational movements. In use, the manual crushing and stirring device for rapidly dissolving clumped chemicals involves placing the support 4 across the port of a container and placing the crushing and stirring head 3 inside. The operator then holds the operating handle 1 and performs pressing, pulling, and rotating operations, allowing the crushing and stirring head 3 to easily crush the clumped chemicals in the container and mix them with the solution. This device is simple in structure, easy to operate, and low in cost, and can integrate efficient crushing and rapid dissolution of solid materials.

[0024] As an optional implementation, the crushing and stirring head 3 is provided with multiple through ports 31, which can be used to quickly and uniformly crush agglomerated chemicals when they are pressed down. At the same time, when rotating, the through ports 31 can also promote the flow of water, so that the powder and solution can be quickly and gently mixed to prevent precipitation.

[0025] As an optional implementation, the crushing and stirring head 3 is detachably connected to the rod body 2, and the crushing and stirring head 3 and the rod body 2 can be threaded together for easy replacement. The corresponding crushing and stirring head 3 can be replaced according to different types of containers.

[0026] As an optional implementation, the external structure of the crushing and stirring head 3 is adapted to the internal cross-sectional shape of the container in order to avoid the formation of dead zones in the stirring, so that the agglomerated chemicals can be completely crushed and mixed with the solution.

[0027] As an optional implementation, the support member 4 has a through hole in the middle, through which the rod 2 passes. The rod 2 can rotate and move up and down relative to the through hole. Alternatively, the support member 4 has a strip-shaped hole in the middle, through which the rod 2 passes. The rod 2 can rotate, move up and down, and move laterally relative to the through hole. If the length of the crushing and stirring head 3 is smaller than the length of the cross-sectional shape of the container's interior, a strip-shaped hole can be used, allowing the crushing and stirring head 3 to move laterally and thus contact all parts of the container's interior, avoiding dead zones.

[0028] As an optional implementation, the support member 4 includes a support rod 41 and two limiting strips 42. The limiting strips 42 are located below the support rod 41 and are fixedly connected to the support rod 41. Alternatively, the limiting strips 42 and the support rod 41 can be locked together by a locking device, allowing the limiting strips 42 to slide relative to the support rod 41. Loosening the locking device allows the limiting strips 42 to slide relative to the support rod 41; tightening the locking device prevents the limiting strips 42 from sliding relative to the support rod 41. This allows adjustment of the distance between the two limiting strips 42, accommodating containers of various sizes. In use, the support rod 41 spans the container's port, and the limiting strips 42 are located inside the container with their outer walls fitting against the container's inner wall. The two limiting strips 42 are located on either side of the container's port, thus restricting the support member 4 from moving radially along the container.

[0029] As an optional implementation, the outer wall of the limiting strip 42 is provided with an arc-shaped structure in order to better fit with the inner wall of the container and increase the contact area between the two.

[0030] As an optional implementation, both the rod body 2 and the crushing and stirring head 3 are made of chemically inert materials. The chemically inert materials can be made of polytetrafluoroethylene (PTFE), which is corrosion-resistant, rust-proof, and prevents pollution.

[0031] As an optional implementation, the rod 2 has a hollow structure, which saves costs and reduces weight. The outer wall of the operating handle 1 can be provided with anti-slip texture.

[0032] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
