Description

Technical Field

[0001] This utility model relates to the field of mineral powder sampling technology, and in particular to a multi-purpose sample preparation tool. Background Technology

[0002] In many fields such as mineral processing, geological exploration, materials analysis, and laboratory sample preparation, ore samples are crushed and ground to obtain a large amount of fine mineral powder. The accurate preparation, separation, and transfer of these mineral powders are crucial for subsequent key analytical steps such as chemical analysis, X-ray diffraction, and particle size analysis.

[0003] However, current traditional methods for preparing and collecting mineral powder samples typically use simple tools such as spoons, shovels, or homemade paper funnels, which have many obvious shortcomings:

[0004] Significant sample loss: Due to the fine size of the mineral powder particles, they are easily scattered and blown away during shoveling, pouring, and transfer, which can lead to sample loss. This is especially true for rare or valuable samples, and will seriously affect the accuracy of the analysis results.

[0005] Inconvenient to operate: Traditional tools often have limited functions. For example, a spoon is easy to scoop but has difficulty in accurately guiding the flow, while a paper funnel is good for guiding the flow but not easy to scoop. Therefore, in actual operation, tools need to be changed frequently, which greatly reduces work efficiency.

[0006] Risk of cross-contamination: Simple tools are difficult to clean and are hard to clean thoroughly, which can easily leave residues from the previous batch of samples, leading to cross-contamination between different batches of samples.

[0007] Inefficiency: The cumbersome sample preparation and collection process increases the workload of experimental staff, leading to a decrease in overall experimental efficiency.

[0008] Based on the above problems, there is an urgent need for a mineral powder sample preparation tool that can solve the above drawbacks, integrate multiple functions, be easy to operate, efficient, and reduce sample loss. Utility Model Content

[0026] 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.

[0027] The purpose of this invention is to provide a multi-purpose sample preparation tool to solve the problems existing in the prior art. It has a simple structure, is easy to use and operate, effectively improves work efficiency, and effectively reduces sample loss and cross-contamination.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] This utility model provides a multi-purpose sample preparation tool, such as... Figures 1-2 As shown, the tool body has a recessed area for supporting powder. The design of the recessed area provides a stable support space for the powder, which can effectively gather and contain the powder, prevent the powder from scattering, provide a good foundation for subsequent sample preparation operations, and improve the sample collection efficiency and stability.

[0030] The concave area features an upward-curving arc-shaped guide surface at its front end, flanked by outward-expanding guide surfaces on both sides. These surfaces are smoothly connected, forming a flared structure. The upward-curving arc-shaped guide surface facilitates the upward and forward flow of powder, allowing it to enter the target container more smoothly and reducing powder residue during transfer. The outward-expanding guide surfaces expand the collection area when scooping powder, making it easier to gather surrounding powder. The smoothly connected flared structure ensures smooth powder flow, preventing jamming or splashing, and effectively improving powder transfer efficiency and accuracy.

[0031] In a preferred embodiment, the tool body includes a base plate 1 and two side plates 2. The two side plates 2 are fixedly connected to both sides of the base plate 1 and extend upwards, forming a recessed area with the base plate 1. An arc-shaped flow guide surface is located at the front end of the base plate 1, and the front end of the side plates 2 serves as a guide surface. This structural design clearly defines the components of the recessed area, making the tool's structure clearer and more stable. The upward extension of the side plates 2 effectively prevents powder from scattering to both sides, further improving the powder-holding capacity. Simultaneously, by placing the arc-shaped flow guide surface and the guide surface at the front ends of the base plate 1 and side plates 2 respectively, a reasonable layout of each functional area is achieved, facilitating better utilization of each part in actual operation.

[0032] In a preferred embodiment, the ratio of the extension height of the side plate 2 to the width of the base plate 1 is not less than 0.5. This ratio ensures that the side plate 2 has sufficient height to prevent powder spillage. When the height of the side plate 2 and the width of the base plate 1 meet this condition, it can effectively prevent powder from spilling from the side due to excessive accumulation or external force when the tool is holding powder, thereby better protecting the sample, reducing sample loss, and improving the accuracy of sample preparation.

[0033] In a preferred embodiment, the base plate 1 and the side plate 2 are integrally formed. This integral structure strengthens the connection between the base plate 1 and the side plate 2, reducing the risk of powder leakage due to loosening or gaps in the connection. Furthermore, the integral forming manufacturing process is relatively simple, which helps improve production efficiency, reduce production costs, and also enhances the overall durability of the tool.

[0034] In a preferred embodiment, the tool body is formed by metal stamping or injection molding. Metal stamping can quickly manufacture tool bodies with specific shapes and precision using molds, resulting in high production efficiency and suitability for mass production. Furthermore, stamped metal tools possess high strength and durability. Injection molding, on the other hand, can produce tool bodies with complex shapes and rich details, better meeting diverse design requirements. It also allows for the selection of various plastic materials to provide different performance characteristics, such as insulation and corrosion resistance.

[0035] In a preferred embodiment, the tool body is made of stainless steel, polypropylene, or polytetrafluoroethylene (PTFE). Stainless steel tool bodies offer excellent corrosion resistance, high strength, and easy cleaning, enabling them to withstand harsh working environments, withstand long-term use without damage, and are easy to keep clean and hygienic, preventing sample contamination. Polypropylene is lightweight, low-cost, and chemically stable, making it suitable for applications with specific weight and cost requirements, while also meeting general corrosion resistance needs. PTFE offers excellent chemical corrosion resistance, low friction, and self-lubricating properties, making it ideal for specialized sample preparation tasks requiring extremely high chemical stability and minimal powder residue.

[0036] In a preferred embodiment, the tool also includes a grip 3 connected to the rear end of the tool body. The grip 3 is designed to facilitate handheld operation of the tool. During operation, the user can better control the movement and force of the tool through the grip 3, improving the accuracy and convenience of operation and avoiding problems such as powder spillage or tool damage caused by inconvenient operation.

[0037] In a preferred embodiment, the grip 3 is a ring-shaped or rod-shaped structure. A ring-shaped grip 3 allows the user's fingers to naturally wrap around it, providing a comfortable grip experience, especially suitable for extended use. Simultaneously, the ring-shaped structure helps the user better control the tool's direction and angle, enhancing operational stability. A rod-shaped grip 3 is relatively simple and direct. In certain operational scenarios, such as when quick and flexible tool use is required, the rod-shaped structure provides a concise grip method, facilitating quick grasping and operation of the tool.

The above description of the embodiments is only for the purpose of helping to understand the method and core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. In summary, the content of this specification should not be construed as a limitation of this utility model.
