A detachably assembled soil column for leaching experiments

Abstract

This utility model discloses a detachable and assembleable soil leaching experimental soil column, including a collection tank. Multiple soil column bottles are movably mounted on the top of the collection tank. A leaching tank is movably mounted on the top of the uppermost soil column bottle. Each soil column bottle has a top plate fixedly mounted on its top and a bottom plate fixedly mounted on its bottom. Each top surface of each soil column bottle has a mounting groove, and a filter tray is movably mounted inside each mounting groove. This utility model utilizes the cooperation of fixed vertical and horizontal plates. When assembling the soil column bottles, the fixed vertical and horizontal plates are first inserted into the insertion arc groove. Then, rotating the upper soil column bottle causes the fixed vertical plate to rotate and engage with the limiting arc groove. At this point, the fixed horizontal plate is locked below the bottom plate, preventing the soil column bottles from being directly pulled upwards for disassembly, thus improving the stability of the soil column bottles.

Description

Technical Field

[0001] This utility model relates to the field of soil leaching experiment technology, specifically a detachable and assembleable soil column for soil leaching experiments. Background Technology

[0002] Leaching refers to the process by which soluble or suspended compounds (clay particles, organic matter, soluble salts, carbonates, and iron and aluminum oxides, etc.) in soil materials migrate from the upper to the lower parts of the soil or undergo lateral migration under the action of seepage water. This process is ubiquitous in soil and includes leaching, chelation leaching, and mechanical leaching. During leaching, soil materials may undergo dissolution, chemical extraction, chelation, and mechanical leaching. To intuitively understand soil leaching, soil experimental setups are often used for simulation experiments.

[0003] Existing soil leaching experimental columns often have limited capacity to hold a certain number of soil species, making it difficult to meet the required number of soil species for experiments. Therefore, we propose a detachable and assembleable soil leaching experimental column to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a detachable and assembleable soil column for soil leaching experiments, in order to solve the problems mentioned in the background art, such as the limited number of soil types that the soil column itself can hold, making it difficult to meet the required number of soil types for experiments.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a detachable and assembleable soil leaching experimental soil column, including a collection tank, a plurality of soil column bottles are movably installed on the top of the collection tank, a leaching tank is movably installed on the top of the uppermost soil column bottle, a top plate is fixedly installed on the top of each soil column bottle, a bottom plate is fixedly installed on the bottom of each soil column bottle, and an installation groove is provided on the top surface of each soil column bottle, and a filter tray is movably installed inside the installation groove.

[0006] Preferably, a top plate is fixedly installed at the top of the liquid collection tank, and a bottom plate is fixedly installed at the bottom of the liquid dissolving tank.

[0007] Preferably, four fixed vertical plates are fixedly installed at the bottom end of the base plate, and a fixed horizontal plate is fixedly installed at the bottom end of each fixed vertical plate.

[0008] Preferably, the surface of the top plate is provided with four insertion arc grooves, the inner surface of each insertion arc groove is provided with a limiting arc groove, the fixed vertical plate and the fixed horizontal plate are movably inserted into the interior of the insertion arc groove, and the fixed vertical plate is movably inserted into the interior of the limiting arc groove.

[0009] Preferably, the inner wall surface of the limiting arc groove is provided with a spring groove, the inside of the spring groove is slidably installed with a limiting block, a compression spring is movably installed between the limiting block and the inside of the spring groove, and the limiting block is in contact with the surface of the fixed vertical plate.

[0010] Preferably, a direction indicator plate is fixedly installed on the outer surface of the top plate.

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

[0012] 1. This utility model, through the combination of soil column bottles and filtrate tray, allows multiple soil column bottles to be vertically spliced ​​together according to the required number of soil types for the experiment, thereby increasing the number of soil types that can be placed, and placing the soil between the soil column bottles and the filtrate tray, thus facilitating the experiment.

[0013] 2. This utility model, through the cooperation of the fixed vertical plate and the fixed horizontal plate, allows the device to first insert the fixed vertical plate and the fixed horizontal plate into the insertion arc groove when assembling the soil column bottle. At this time, the upper soil column bottle is rotated, causing the fixed vertical plate to rotate and lock into the limiting arc groove. At this time, the fixed horizontal plate will be locked in the lower position of the bottom plate, so that the soil column bottles cannot be directly pulled upwards for disassembly, thus improving the stability between the soil column bottles.

[0014] 3. This utility model, through the cooperation of the limiting block and the compression spring, allows the device to be used so that when the fixed vertical plate needs to be inserted into the limiting arc groove, the limiting block can be pushed into the spring groove from below the limiting arc groove, so that the limiting block retracts into the spring groove. Then, the fixed vertical plate is inserted into the limiting arc groove. At this time, the limiting block will be ejected by the elastic potential energy of the compression spring and jam into the insertion arc groove. In this way, the limiting block blocks the fixed vertical plate, preventing the soil column bottles from automatically falling off due to accidental contact or other reasons, thus improving the stability between the soil column bottles.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 5 One embodiment of this utility model is a detachable and assembleable soil leaching experimental soil column, including a collection tank 1, multiple soil column bottles 2 are movably installed on the top of the collection tank 1, a leaching tank 3 is movably installed on the top of the uppermost soil column bottle 2, a top plate 5 is fixedly installed on the top of each soil column bottle 2, a bottom plate 4 is fixedly installed on the bottom of each soil column bottle 2, and an installation groove 7 is provided on the top surface of each soil column bottle 2, and a filter plate 6 is movably installed inside the installation groove 7.

[0023] By combining the soil column bottle 2 and the filtrate tray 6, multiple soil column bottles 2 can be vertically spliced ​​together according to the number of soil types required for the experiment, thereby increasing the number of soil types that can be placed. The soil is then placed between the soil column bottle 2 and the filtrate tray 6, which facilitates the experiment.

[0024] A top plate 5 is fixedly installed at the top of the liquid collection tank 1, and a bottom plate 4 is fixedly installed at the bottom of the liquid dissolving tank 3.

[0025] Four fixed vertical plates 10 are fixedly installed at the bottom of the base plate 4, and a fixed horizontal plate 11 is fixedly installed at the bottom of each fixed vertical plate 10.

[0026] The surface of the top plate 5 is provided with four insertion arc grooves 8, and the inner surface of each insertion arc groove 8 is provided with a limiting arc groove 9. The fixed vertical plate 10 and the fixed horizontal plate 11 are both movably inserted into the interior of the insertion arc groove 8, and the fixed vertical plate 10 is also movably inserted into the interior of the limiting arc groove 9.

[0027] By using the fixed vertical plate 10 and the fixed horizontal plate 11 together, when assembling the soil column bottle 2, the fixed vertical plate 10 and the fixed horizontal plate 11 can be inserted into the insertion arc groove 8 first. At this time, the upper soil column bottle 2 is rotated, so that the fixed vertical plate 10 is rotated and locked into the limiting arc groove 9. At this time, the fixed horizontal plate 11 will be locked in the lower position of the bottom plate 4, so that the soil column bottles 2 cannot be directly pulled upwards for disassembly, thus improving the stability between the soil column bottles 2.

[0028] The inner wall surface of the limiting arc groove 9 is provided with spring grooves 12. Limiting blocks 13 are slidably installed inside the spring grooves 12. Compression springs 14 are movably installed between the limiting blocks 13 and the inside of the spring grooves 12. The limiting blocks 13 are all in contact with the surface of the fixed vertical plate 10.

[0029] With the cooperation of the limiting block 13 and the compression spring 14, when the device is in use, if it is necessary to insert the fixed vertical plate 10 into the limiting arc groove 9, the limiting block 13 can be pushed into the spring groove 12 from below the limiting arc groove 9, so that the limiting block 13 retracts into the spring groove 12. Then, the fixed vertical plate 10 is inserted into the limiting arc groove 9. At this time, the limiting block 13 will be ejected by the elastic potential energy of the compression spring 14 and jammed into the insertion arc groove 8. Thus, the limiting block 13 blocks the fixed vertical plate 10, so that the soil column bottles 2 will not fall off automatically due to accidental contact or other reasons, thereby improving the stability of the soil column bottles 2.

[0030] Direction indicator plates 15 are fixedly installed on the outer surface of the top plate 5.

[0031] When using this detachable and assembleable soil leaching experimental soil column, multiple soil column bottles 2 are first vertically spliced ​​together according to the required soil type and quantity for the experiment. Each time the column is spliced, the filtrate tray 6 is removed from the mounting slot 7, and soil is added to the inside of the soil column bottle 2. Then, the filtrate tray 6 is placed back into the mounting slot 7, and the next soil column bottle 2 is installed.

[0032] When assembling the soil column bottle 2, the fixed vertical plate 10 and the fixed horizontal plate 11 can be inserted into the insertion arc groove 8 first. Then, rotate the upper soil column bottle 2 so that the fixed vertical plate 10 rotates and locks into the limiting arc groove 9. At this time, the fixed horizontal plate 11 will be locked in the lower position of the bottom plate 4, so that the soil column bottles 2 cannot be directly pulled upwards for disassembly, thus improving the stability between the soil column bottles 2.

[0033] When it is necessary to insert the fixed vertical plate 10 into the limiting arc groove 9, the limiting block 13 can be pushed into the spring groove 12 from below the limiting arc groove 9, so that the limiting block 13 retracts into the spring groove 12. Then, the fixed vertical plate 10 is inserted into the limiting arc groove 9. At this time, the limiting block 13 will be ejected by the elastic potential energy of the compression spring 14 and jam into the insertion arc groove 8. Thus, the limiting block 13 blocks the fixed vertical plate 10, preventing the soil column bottles 2 from automatically falling off due to accidental contact or other reasons, thereby improving the stability between the soil column bottles 2.

[0034] When it is necessary to separate the soil column bottle 2 and clean it, the limiting block 13 can be pushed into the spring groove 12 from below the limiting arc groove 9, so that the limiting block 13 retracts into the spring groove 12. At this time, the soil column bottle 2 can be rotated to move the fixed vertical plate 10 from the limiting arc groove 9 to the position of the insertion arc groove 8. At this time, the soil column bottle 2 can be pulled upward directly to complete the disassembly of the soil column bottle 2, thus facilitating the cleaning operation of the soil column bottle 2.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
