Description

Technical Field

[0001] This utility model relates to the field of ore sorting technology, specifically a novel ore sorting basin. Background Technology

[0002] Gravity separation is a traditional method of separating minerals based on differences in mineral density, with the gold pan being a representative tool. Traditional gold pans are mostly made of metal or wood, which has drawbacks such as susceptibility to corrosion and deformation, heavy weight, and inconvenience in carrying. Although some improved designs using plastic materials have been developed, there is still room for improvement in separation efficiency. Existing gold pans largely rely on the user's experience in shaking them. Their inner bottoms are usually smooth or have simple textures. During the horizontal shaking enrichment stage, heavy mineral particles tend to diffuse at the bottom of the pan due to inertia, making it difficult to efficiently concentrate them in the central area, potentially leading to the loss of valuable minerals such as fine-grained gold. Furthermore, the one-piece structure makes it inconvenient to clean particles stuck in the bottom holes or to replace specific parts. Utility Model Content

[0003] To address the aforementioned problems, this application provides a novel ore sorting basin, employing the following technical solution:

[0004] A novel ore sorting basin includes a basin body and a base, both of which have trapezoidal cross-sections. The basin body is positioned above the base. The bottom of the basin body has evenly distributed through holes, and the top of the side wall of the basin body has a top edge. The outer diameter of the basin bottom is larger than the inner diameter of the central area of ​​the base, and the outer diameter of the top edge of the basin body is smaller than the inner diameter of the top of the base. One side of the base is configured as a stepped sedimentation enrichment zone, which consists of multiple steps that gradually decrease from the basin wall to the center of the basin.

[0005] Furthermore, the inner bottom surface of the base is also provided with a vortex generation zone, which is composed of concentric arc-shaped protrusions or textures and is arranged adjacent to the stepped sedimentation enrichment zone.

[0006] Furthermore, the base includes the eddy current generation zone, the stepped sedimentation enrichment zone, and at least one smooth transition zone. The upper surface of the stepped sedimentation enrichment zone of the base is divided into different functional zones by radially extending dividing lines.

[0007] Furthermore, the bottom center of the base is set as a gathering area, and the gathering area is set as a flat bottom surface.

[0008] Furthermore, the basin can be detachably nested on the base, and the two are fixedly connected by a snap-fit ​​structure. The snap-fit ​​structure includes a buckle on the outside of the basin and a slot on the inner edge of the base, or vice versa, so that the basin can be securely snapped into the base.

[0009] Furthermore, the basin and the base are designed as an integral structure.

[0010] Furthermore, both the basin and the base are integrally injection molded from engineering plastics.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] High sorting efficiency: The stepped sedimentation enrichment zone can actively guide heavy minerals to the center for enrichment, and the eddy current generation zone optimizes the eddy effect. The two work together to significantly reduce the loss of useful minerals, making it especially suitable for beginners.

[0013] Scientific functional zoning: The scientific zoning of the inner bottom materializes the sorting process into the tool structure, making the operation more standardized and reducing the reliance on operator experience.

[0014] Flexible and portable design: The modular snap-fit ​​design ensures stability while facilitating carrying, storage, and component cleaning. The integrated structure offers better overall integrity.

[0015] Durable and economical: Made of engineering plastics, it is low-cost and long-lasting, making it particularly suitable for field exploration and teaching. Attached Figure Description

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments of this utility model.

[0025] Please refer to the details. Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, a novel ore sorting basin includes a basin body 1 and a base 2. Both the basin body 1 and the base 2 have trapezoidal cross-sections. Both the basin body 1 and the base 2 are integrally injection molded from engineering plastics (such as reinforced polypropylene). Integral injection molding has the advantages of being drop-resistant, wear-resistant, corrosion-resistant, and lightweight. The basin body 1 is positioned above the base 2. The bottom 13 of the basin body 1 has evenly distributed bottom through holes 14. The top of the side wall 12 of the basin body 1 has a top edge 11. The outer diameter of the bottom 13 is larger than the inner diameter of the middle area of ​​the base 2, and the outer diameter of the top edge 11 is smaller than the inner diameter of the top of the base 2. A stepped sedimentation enrichment zone 26 is set on one side of the base 2. The stepped sedimentation enrichment zone 26 is composed of multiple steps that gradually decrease from the basin wall to the center of the basin. This structure can effectively intercept and guide heavy mineral particles like a series of miniature "dams" when the object is shaken horizontally, causing them to gradually accumulate in the center of the basin, thus greatly improving the recovery rate of heavy minerals.

[0026] The inner bottom surface of the base 2 is also provided with a vortex generation zone 22, which is composed of concentric arc-shaped protrusions or textures and is adjacent to the stepped sedimentation enrichment zone 26. This zone can effectively promote the formation of stable vortices when circumferentially oscillating, which is conducive to the discharge of light gangue. The base 2 includes a vortex generation zone 22, a stepped sedimentation enrichment zone 26 and at least one smooth transition zone 21. The upper surface of the stepped sedimentation enrichment zone 26 of the base 2 is divided into different functional areas by radially extending dividing lines 23 and 24. The bottom center of the base 2 is set as an aggregation zone 25, and the aggregation zone 25 is set as a flat bottom surface. The aggregation zone is set as a flat bottom surface to facilitate the collection of the final concentrate.

[0027] In Embodiment 1, the basin body 1 can be detachably nested on the base 2, and the two are fixedly connected by a snap-fit ​​structure. The snap-fit ​​structure includes a buckle set on the outside of the basin body 1 and a slot set on the inner edge of the base 2, or vice versa, so that the basin body 1 can be firmly snapped into the base 2. The two are fixedly connected by a snap-fit ​​structure (such as a buckle and a slot), which realizes quick assembly and separation, facilitates transportation and cleaning. The detachable structure makes it convenient to replace the basin bottom through hole 14 structure of different sizes during use, thereby adapting to different ore screening. Moreover, it is convenient to directly separate the basin body 1 during use, thus facilitating direct observation.

[0028] In Example 2, the basin 1 and the base 2 are designed as an integrated structure, which is convenient for operation and carrying, and meets the needs of some coarse screening and separation applications.

[0029] Working principle:

[0030] 1. Loading and Immersion

[0031] Procedure: Assemble basin 1 and base 2. Place an appropriate amount of sand and ore raw material into the basin, then immerse the entire basin in water until the material is completely submerged, and then slowly lift it out. At this time, the holes at the bottom of the basin will begin to drain water, carrying away some of the fine mud.

[0032] Principle: The material is fully wetted and extremely fine particles are initially separated to prepare for subsequent sorting.

[0033] 2. Eddy current waste disposal

[0034] Operation: Hold the basin and tilt it slightly. Shake it in a circular motion to make the water and materials inside the basin rotate. At this time, the concentric circle texture of the vortex generation zone 22 will greatly promote the formation of a stable vortex flow field.

[0035] Principle: Under the action of centrifugal force, light sand and gravel with low density will be thrown to the edge of the basin and overflow with the water flow. Meanwhile, heavy minerals with high density, due to their greater inertia, will overcome the centrifugal force and gradually settle towards the center of the basin bottom.

[0036] 3. Horizontal shaking enrichment

[0037] Operation: After the eddy current has released waste to a certain extent, level the basin and shake it horizontally back and forth and side to side. This step is crucial.

[0038] Principle: At this point, the stepped sedimentation enrichment zone 26 begins to play a decisive role.

[0039] Layered interception: Under horizontal shaking, the material slides at the bottom of the basin. Heavy mineral particles are effectively blocked and captured when they collide with the vertical surface of the steps during movement.

[0040] Directional flow: Because the steps gradually decrease towards the center of the basin, the captured heavy minerals will naturally roll to the next lower step under the influence of gravity and water flow, eventually accumulating in the deepest part of the basin bottom.

[0041] Highly efficient separation: This design greatly prevents the disorderly diffusion and "rolling" of heavy minerals at the bottom of the basin, ensuring that heavy minerals such as gold can be quickly and concentratedly enriched and completely separated from light waste sand.

[0042] 4. Repetition and Concentration

[0043] Procedure: Repeat steps 2 and 3 several times. Each repetition will further eliminate more lightweight waste. Finally, only a small amount of "concentrate" composed of heavy minerals (such as gold, magnetite, etc.) will remain in the basin.

[0044] Final processing: The concentrate can be poured into a small dish for final fine selection.

[0045] The brilliance of this technical solution lies in its embodiment of the experience-based "washing hands" technique into the physical structure of the basin:

[0046] The vortex generation zone 22 optimizes the generation of "vortexes" and efficiently removes waste.

[0047] The stepped sedimentation enrichment zone 26 is the core of the technology. It actively guides, intercepts and enriches heavy minerals through a stepped structure, solving the problem of heavy minerals being easily dispersed when the traditional flat-bottomed basin is shaken horizontally. This significantly improves the recovery rate and sorting efficiency, making it especially suitable for beginners and rapid field exploration.

[0048] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
