Description

[Technical field]

[0001] The present invention relates to a wet sieving apparatus, and more particularly to an integrated sieving apparatus for sorting the grain size of soil samples, which greatly facilitates grain size sorting and collection by wet sieving. [Background technology]

[0002] As soil particles become smaller, their chemical reactivity increases, and when they are present with water, they become more mobile due to mudflows. For this reason, soil particles must be separated by size.

[0003] For example, when cleaning up contaminated soil, the distribution of contamination varies depending on the particle size, so the most appropriate cleaning method is chosen depending on the particle size. Also, when creating a geochemical map, it is necessary to collect and analyze particles of specific sizes from river sediment.

[0004] A particle size sorting device is used to separate soil by particle size. Conventional particle size sorting devices are mainly large-capacity complex equipment that is only available in the form of powered operation, and no device suitable for sorting small amounts of samples and that is easy to move and carry has been developed.

[0005] Therefore, when some samples need to be separated without external power, they can be repeatedly shaken using a sieve of an appropriate size. However, this method requires high-intensity labor, is difficult to work for long periods of time, and is an open system, so there is a problem that particles of undesired sizes may be mixed in as impurities.

[0006] For this reason, as mentioned above, when preparing geochemical maps or when investigating samples while moving between different regions, a small-scale, highly portable grain size sorting device is required.

[0007] Conventional wet-sieving uses a standard sieve used to separate the grain size of soil samples. The sieve diameter used is 7.5 cm, and the mesh size of the sieve is classified according to size, so a sieve with a mesh size that matches the size of the desired sediment particles is selected and used alone.

[0008] In particular, when wet-sieving, a brush or a pen must be used to loosen the solidified sediments sufficiently, and distilled water must be continuously supplied to the sediments. At this time, the coarse particles remaining on the sieve are finally collected, and the fine particles that pass through the sieve are allowed to flow through.

[0009] Also, when sifting highly cohesive clayey sediments, the clumped sediments must be loosened using a brush or writing brush, and distilled water must be continually supplied to the sediments.

[0010] The problem with this is that while holding a sieve in one hand and a brush in the other to loosen the sediments, it is not possible to continuously supply distilled water from a distilled water bottle, so it is necessary to place the sieve or brush at the bottom for a while and then pour distilled water over it, which can result in contamination or loss of samples.

[0011] In addition, when recovering not only the coarse sediments remaining on the sieve but also the fine sediments that passed through the sieve, a beaker must be supported under the sieve, but because the beaker and sieve are not fixed, there is a problem in that a large amount of sediments may be lost during the sieving process.

[0014] Another object of the present invention is to provide an integrated sieve device for separating the particle size of soil samples, which provides an adjustable sieve angle and a detachable structure, so that after sieving is completed, the sieve can be tilted sufficiently to collect all of the separated sediments on the sieve without losing any of them, and can be detached and washed once collection is complete, thereby providing an integrated sieve device for separating the particle size of soil samples, which provides efficient sieving operations and is very easy to prepare and wash.

[0049] In the following, preferred embodiments of the present invention will be described in detail with reference to the drawings.

[0050] FIG. 1 is an exploded perspective view of an integrated sieving device for sorting the particle size of a soil sample according to the present invention, FIG. 2 is an assembled perspective view of an integrated sieving device for sorting the particle size of a soil sample according to an embodiment of the present invention, FIG. 3 is a diagram showing a layered particle size sorting unit applied to an integrated sieving device for sorting the particle size of a soil sample according to an embodiment of the present invention, FIG. 4 is a diagram showing various sieve meshes of a layered particle size sorting unit applied to an integrated sieving device for sorting the particle size of a soil sample according to an embodiment of the present invention, and FIG. 5 is a side view of an integrated sieving device for sorting the particle size of a soil sample according to an embodiment of the present invention.

[0051] As shown in Figures 1 and 2, an integrated sieve device for sorting the grain size of a soil sample according to an embodiment of the present invention may be configured to include a grain size sorting section 200, a body housing 100, a sample receiving section 300, and a water supply section 400.

[0052] The grain size sorting section 200 may be a device that sorts soil samples by grain size, and may be a device that includes at least one sieve and sorts the input soil sample by grain size and drops it.

[0053] As shown in Figures 1 and 2, the grain size sorting unit 200 may be formed of a sieve including a ring-shaped frame 210 and an elliptical mesh 230 attached to the inner bottom of the ring-shaped frame 210 for sieving the soil sample.

[0054] Also, as shown in Figures 2 and 3, the grain size sorting unit 200 may be configured as a single sieve consisting of one of these sieves, or may be configured as a device in which multiple sieves are stacked to filter and sort soil samples of various grain sizes.

[0055] The sieve is preferably sized to have a diameter not exceeding approximately 8 cm, and may be configured to be inserted and attached in the open direction of the body housing 100 so that the sample receiving section 300 (collector) is located below the particle size sorting section 200.

[0056] As shown in FIG. 4, the particle size separation unit 200 formed by stacking a number of sieves has different mesh hole sizes for each sieve mesh 230, but it is preferable that the mesh hole size becomes smaller from the top to the bottom.

[0057] This is to allow the various sizes of samples contained in the soil sample to be filtered out sequentially according to the mesh hole size, and by stacking multiple sieve screens 230 with pre-set mesh hole sizes, the soil sample can be effectively sorted by grain size.

[0058] As shown in FIG. 5, the particle size separator 200 is preferably an elliptical disk that is long in both length directions when connected to the body housing 100, because it is rotated based on a structure that connects or joins to both inner sides of the body housing 100 described below, and forms a separation space between the rear of the particle size separator 200 and the inner side of the body housing 100 so that the sieve screen 230 is tilted.

[0059] As shown in Figs. 1 and 2, the body housing 100 may be a housing device that is cylindrical, has one side open, and has the particle size separator 200 detachably coupled to the inner side in the opening direction.

[0060] As shown in Figures 1 and 2, the body housing 100 may have convex portions 115 formed on both of its inner surfaces, and groove portions 215 formed on both of its outer surfaces of the particle size sorting unit 200 may be combined to form a structure that allows the particle size sorting unit 200 to rotate at a preset angle.

[0061] In addition, the pivotal connection structures of both inner surfaces of the body housing 100 and the particle size separator 200 may be formed as a detachable hinge structure.

[0062] In this way, the grain size sorting unit 200 is structured so that it can be inserted into the open surface of the body housing 100 and attached / detached, thereby providing an apparatus that can easily attach and detach sieves having mesh holes of various sizes to sort soil samples by grain size according to the application and purpose.

[0063] In addition, the structure in which both grooves 215 of the size separator 200 are inserted into both protrusions 115 of the body housing 100 to enable rotation can tilt the size separator 200 at a constant angle.

[0064] In this manner, the grain size sorting unit 200 is connected to the body housing 100 so that it is tilted toward the user so that the user can easily and gently brush the soil sample placed on the sieve for sieving.

[0065] As shown in FIG. 5, when the particle size sorting unit 200 rotates at the upper end of the convex portion 115 along the inner peripheral surface of the body housing 100, it is preferable to form a linear locking groove 135 for locking and fastening at the lower corner.

[0066] More specifically, the particle size sorting unit 200 has a structure in which a ring-shaped or elliptical cylindrical frame having a certain thickness and a sieve screen 230 (mesh) is formed on the inner surface, and the body frame has a structure in which a portion of the front surface is open to the cylindrical housing. The particle size sorting unit 200 exposed to the open structure can rotate freely, but since the particle size sorting unit 200 is adjacent to the inner surface of the rear of the body housing 100, its rotation may be restricted. Therefore, in order to form a separation distance that allows it to rotate at a certain angle, it is preferable that the shape of the particle size sorting unit is an ellipse that is long in the direction of the rotation axis.

[0067] 5, a structure that is fixed in an inclined position is preferable so that a user can conveniently use a brush to brush the soil sample placed on the sieve screen 230. When the grain size separator 200 rotates, the lower corner of the rear stage comes into contact with a part of the rear inner surface of the body housing 100, and by forming a groove on this contact line, a structure can be formed in which the lower corner of the rear stage of the grain size separator 200 is hooked or clamped into the locking groove 135 to be fixed and seated.

[0068] Here, the locking and fixing force with which the lower end corner of the particle size sorting unit 200 engages with the locking groove 135 may be such that it can be easily released when the user applies a certain amount of force, and at the same time, the locking and fixing force may be sufficient to ensure stable sieving using a brush.

[0069] That is, as shown in FIG. 5, a linear engaging groove 135 may be formed along the inner peripheral surface of the body housing 100 at the upper end of the convex portion 115, where the lower corner of the particle size separator 200 is engaged when the particle size separator 200 rotates.

[0070] Here, the distance between the rear surface of the particle size sorting unit 200 and the inner surface of the body housing 100 can determine the angle at which the particle size sorting unit 200 can rotate, and can also determine the position of the above-mentioned linear engagement groove 135.

[0071] As shown in Figures 1 and 2, the sample receiving section 300 may be a device attached to the bottom of the particle size sorting section 200 to collect the soil and water that is sorted by the sieve and discharged below the particle size sorting section 200.

[0072] These sample receiving parts 300 are in the form of a beaker and made of a transparent or semi-transparent material, so that the water and soil sample dropped into the particle size sorting part 200 can be easily confirmed. Also, since they can be easily inserted and attached to the open side of the body housing 100, it has the advantage that the soil sample sieving and collection functions can be performed simultaneously.

[0073] As shown in Figures 1 and 2, the water supply unit 400 is a device that stores and supplies water to be input to the particle size sorting unit 200 for sieving and sorting the soil sample, and may be a device that is attached to an input port formed at the upper end of the body housing 100 and supplies water to the inside of the particle size sorting unit 200.

[0074] In addition, the water supply unit 400 is preferably configured to include a water adjustment unit 410 that is attached to the inlet and adjusts the strength, supply amount, and dispersion of the water being supplied, and a water bottle unit 420 that stores water and has an inlet attached to the upper end of the water adjustment unit 410.

[0075] That is, the water adjusting part 410 may be attached to an inlet formed at the center of the upper end of the body housing 100, and a water bottle-shaped water bottle part 420 may be attached to the small tubular water adjusting part 410.

[0076] Here, the water adjusting unit 410 may have a shower head structure (not shown) in which two or more disk-shaped injection pipes having a plurality of through-holes of different sizes are connected and the size of the water through-holes can be adjusted by rotating any one of the injection pipes.

[0077] The structure of the injection pipes having different sizes of through holes stacked vertically and arranged differently has an advantage that when any of the injection pipes is rotated, the two injection pipes cross each other and the through holes formed in common of each of the through holes have different sizes, and the water supply unit 400 can be opened and closed. Also, the water injection pressure can be adjusted by adjusting the size of the water through holes through which the water passes.

[0078] The integrated sieving device for sorting the grain size of a soil sample according to the embodiment of the present invention has the following advantages and effects.

[0079] 1) Ease of operation: Users can easily access the sieve directly and visually monitor and manage the sieving process. The sieve and the beaker-type collector can be separated, the cleaning process is simple, and parts can be replaced or exchanged according to the requirements of the sieving process.

[0080] 2) Improved sieving efficiency: The rotatable sieve design can promote more dynamic sieving, allowing the soil sample to move across the sieve surface, increasing the chances of fine particles passing through.

[0081] The angled sieve structure also allows the user to brush easily, which helps to remove soil particles and improve the sieving process, especially when dealing with sticky or clayey soils.

[0082] 3) Optimized for wet sieving: It has an integrated structure and is equipped with a wet sieving device, which further simplifies the overall process and has the advantage of eliminating the need to assemble or configure various components.

[0083] 4) Controlled water supply: The integrated sieving device for sieving soil samples according to the embodiments of the present invention can regulate the amount and pressure of water supplied to the soil sample, which can improve the efficiency of wet sieving. Also, wet sieving is particularly useful for samples that tend to aggregate or particles that are difficult to sieve under dry conditions.

[0084] 5) Minimization of sample loss: The use of a beaker-type collector or sample receiver 300 allows for efficient directional collection of the sieved sample, reducing the possibility of sample loss or spillage.

[0085] 6) Sorting by grain size and versatile: Not only can users change the sieve to a different mesh size according to their requirements, but the sieves with different mesh sizes are stacked on top of each other, making it easy to sort soil samples by grain size. Therefore, it can be used for a variety of purposes according to various soil types and specific grain size requirements.

[0086] Thus, the integrated sieving apparatus for sorting soil sample particle size according to an embodiment of the present invention provides a balance between functionality, efficiency and user convenience, simplifying the sieving process and ensuring more consistent results, making it a very useful apparatus for soil analysis and similar applications.
