Description

Technical Field

[0001] This utility model relates to the field of soil experimental technology, specifically to a detachable adaptive soil column leaching simulation experimental device. Background Technology

[0002] Leaching refers to the migration of soluble or suspended compounds in soil materials from the upper to the lower layers of the soil under the influence of water transport. This process is common in soil. During leaching, soil materials may undergo dissolution, chemical extraction, chelation, and mechanical leaching. Leaching leads to the loss of materials from the upper soil layer and the formation of leached layers. Soil materials leached from the upper layers of the soil profile to the lower layers often accumulate in the lower layers, forming various deposit layers. Leaching can also cause some soil materials to be completely lost from the soil profile through groundwater and other pathways.

[0003] Most existing leaching simulation experimental devices have integrated leaching columns, which can damage the physical structure of the soil when the soil column is separated at the end of the experiment. This affects the staff's ability to perform stratified sampling and experimental analysis. At the same time, the leaching inlet of existing leaching simulation experimental devices often has concentrated water flow, which can cause the surface soil of the soil column to be eroded, have uneven density, and even form local water accumulation or channel flow, directly affecting the authenticity of the solute migration path. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a detachable, adaptable soil column leaching simulation experimental device, which has the advantages of facilitating subsequent observation and analysis and providing accurate experimental results, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a detachable adaptive soil column leaching simulation experimental device, including a base, a sliding rod snapped onto the upper end face of the base, three fixing mechanisms sliding on the surface of the sliding rod, a drip irrigation mechanism snapped onto one side of the uppermost of the three fixing mechanisms, a leaching column mechanism snapped onto the other two fixing mechanisms, a dispersing mechanism snapped onto the upper end face of the leaching column mechanism, two elastic rings sleeved on the surface of the leaching column mechanism, soil filling the interior of the leaching column mechanism, an outlet pipe snapped onto the lower end face of the leaching column mechanism, a valve fixedly installed on the surface of the outlet pipe, a water receiving tank snapped onto the upper end face of the base, and multiple graduations opened on the front end face of the water receiving tank.

[0006] As a preferred embodiment of the present invention, the fixing mechanism includes a sliding block, an elastic block is fixedly installed on one side of the sliding block, and a fixing bolt is fixedly installed on the other end of the sliding block.

[0007] As a preferred embodiment of this utility model, the drip irrigation mechanism includes a water storage bottle, a water outlet pipe is fixedly installed on the lower end face of the water storage bottle, and a second valve is fixedly installed on the surface of the water outlet pipe.

[0008] As a preferred technical solution of this utility model, the dispersing mechanism includes a limiting plate, and a liquid storage tank is fixedly installed on the lower end face of the limiting plate. The bottom surface of the liquid storage tank is provided with multiple through holes.

[0009] As a preferred technical solution of this utility model, the leaching column mechanism includes a first leaching column body, with locking blocks fixedly installed on both sides of the first leaching column body, and a second leaching column body being locked to one side of the first leaching column body.

[0010] As a preferred technical solution of this utility model, the second leaching column body has snap-fit ​​grooves on both sides, and elastic sealing blocks are fixedly installed on the inner walls of the two snap-fit ​​grooves.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This detachable adaptive soil column leaching simulation experimental device divides the traditional integrated leaching column into two parts. The two parts are interlocked and fixed by snap-fit ​​blocks and snap-fit ​​grooves to form a complete leaching column. At the same time, elastic rings and elastic sealing blocks are used for sealing and fixing. After the leaching experiment is completed, the leaching column can be separated simply by removing the elastic rings. The experimental soil can be completely removed without damaging the physical structure of the soil column, making it convenient for the experimenters to observe the experimental results.

[0013] 2. This detachable adaptive soil column leaching simulation experimental device, by attaching a dispersion mechanism to the upper end of the leaching column mechanism, allows the leaching solution to enter the storage tank through the drip irrigation mechanism. Under the action of the through holes, the leaching solution will be evenly dispersed and dripped into the interior of the leaching column mechanism, thereby avoiding the concentrated dripping of the leaching solution into the interior of the leaching column mechanism, which would cause the surface soil of the soil column to be washed away and affect the accuracy of the experiment.

[0022] Please see Figures 1-6 A detachable adaptive soil column leaching simulation experimental device includes a base 10, a sliding rod 1 is snapped onto the upper end of the base 10, three fixing mechanisms 2 slide on the surface of the sliding rod 1, a drip irrigation mechanism 3 is snapped onto one side of the uppermost of the three fixing mechanisms 2, a leaching column mechanism 5 is snapped onto the other two fixing mechanisms 2, a dispersing mechanism 4 is snapped onto the upper end of the leaching column mechanism 5, two elastic rings 6 are sleeved on the surface of the leaching column mechanism 5, soil 12 is filled inside the leaching column mechanism 5, an outlet pipe 7 is snapped onto the lower end of the leaching column mechanism 5, a valve 8 is fixedly installed on the surface of the outlet pipe 7, a water tank 9 is snapped onto the upper end of the base 10, and multiple scales 11 are opened on the front end of the water tank 9;

[0023] In the above structure, the leaching column mechanism 5 is sealed and fixed by fitting the elastic ring 6 onto the surface of the leaching column mechanism 5. Then, the leaching column mechanism 5 is fixed to one side of the slide rod 1 by two fixing mechanisms 2. Then, the drip irrigation mechanism 3 is fixed to the upper end of the leaching column mechanism 5 by another fixing mechanism 2. The leaching solution is dripped into the leaching column mechanism 5 through the dispersion mechanism 4 by the drip irrigation mechanism 3, so as to carry out the leaching experiment on the soil 12 filled inside the leaching column mechanism 5. The wastewater generated by the experiment is collected into the water tank 9 through the outlet pipe 7. After the experiment, the leaching column mechanism 5 is removed from the fixing mechanism 2 and the elastic ring 6 is removed. Then, the leaching column mechanism 5 is separated and the soil 12 inside is completely removed for analysis, thus completing the experimental analysis.

[0024] In a preferred embodiment, the fixing mechanism 2 includes a sliding block 201, an elastic block 202 is fixedly installed on one side of the sliding block 201, and a fixing bolt 203 is fixedly installed on the other end of the sliding block 201.

[0025] In the above structure, by sliding the sliding block 201 up and down along the slide rod 1, the drip irrigation mechanism 3 and the leaching column mechanism 5 are clamped and fixed in a suitable position on the slide rod 1. After the position is determined, the position of the sliding block 201 is fixed by the fixing bolt 203. The elastic block 202 can increase the friction between the sliding block 201 and the drip irrigation mechanism 3 and the leaching column mechanism 5, so that the two are clamped and fixed more firmly.

[0026] In a preferred embodiment, the drip irrigation mechanism 3 includes a water storage bottle 301, a water outlet pipe 302 is fixedly installed on the lower end face of the water storage bottle 301, and a second valve 303 is fixedly installed on the surface of the water outlet pipe 302.

[0027] In the above structure, the water storage bottle 301 stores the leaching solution, and the flow rate of the water outlet pipe 302 is adjusted by the second valve 303, thereby controlling the experimental process.

[0028] In a preferred embodiment, the dispersing mechanism 4 includes a limiting plate 401, a liquid storage tank 402 is fixedly installed on the lower end face of the limiting plate 401, and a plurality of through holes 403 are opened on the bottom surface of the liquid storage tank 402.

[0029] In the above structure, after the leaching solution is discharged from the water storage bottle 301, it will enter the liquid storage tank 402. Under the action of the through hole 403, it will be evenly and dispersedly dripped into the leaching column mechanism 5 to avoid the leaching solution being too concentrated and affecting the experimental results.

[0030] In a preferred embodiment, the leaching column mechanism 5 includes a first leaching column body 501, with snap-fit ​​blocks 502 fixedly installed on both sides of the first leaching column body 501, and a second leaching column body 503 snapped onto one side of the first leaching column body 501. Snap-fit ​​grooves 504 are provided on both sides of the second leaching column body 503, and elastic sealing blocks 505 are fixedly installed on the inner walls of both snap-fit ​​grooves 504.

[0031] In the above structure, the first leaching column body 501 and the second leaching column body 503 are connected to form a leaching column by interlocking the interlocking block 502 and the interlocking groove 504. The elastic sealing block 505 can not only make the interlocking more secure, but also seal the interlocking gap to prevent the leaching solution from leaking. After leaching is completed, the first leaching column body 501 and the second leaching column body 503 are separated to completely remove the experimental soil 12 for subsequent analysis by the experimental personnel.

[0032] Working principle: The snap-fit ​​block 502 and snap-fit ​​groove 504 interlock to connect the first leaching column body 501 and the second leaching column body 503 into a leaching column. The elastic sealing block 505 not only makes the snap-fit ​​more secure but also seals the snap-fit ​​gaps to prevent leaching solution leakage. At the same time, the elastic ring 6 is sleeved on the surface of the leaching column mechanism 5 to further seal and fix the leaching column mechanism 5. Then, the leaching column mechanism 5 is fixed to one side of the slide rod 1 by two fixing mechanisms 2, and then the drip irrigation mechanism 3 is fixed to the upper end of the leaching column mechanism 5 by another fixing mechanism 2. The drip irrigation mechanism 3 drips the leaching solution into the storage tank 402. Under the action of the through hole 403, the leaching solution will be evenly distributed into the leaching column mechanism 5, avoiding the leaching solution from being too concentrated and affecting the experimental results. The wastewater generated in the experiment will be collected into the water receiving tank 9 through the outlet pipe 7. After the experiment, the leaching column mechanism 5 is removed from the fixing mechanism 2 and the elastic ring 6 is disassembled. Then, by separating the first leaching column body 501 and the second leaching column body 503, the experimental soil 12 can be completely removed, which is convenient for subsequent experimental personnel to analyze the soil 12 and obtain complete experimental results.
