Technical Field

[0001] This utility model relates to the field of dissolving equipment technology, specifically a dissolving device for soil testing. Background Technology

[0002] Soil testing dissolution equipment is mainly used in the pretreatment of soil samples. It releases target analytes (such as heavy metals, organic pollutants, and nutrients) from the solid matrix and converts them into liquid solutions through dissolution, extraction, and other methods, so that they can be quantitatively or qualitatively analyzed by instruments such as spectrometers and chromatographs.

[0003] Utility model patent CN222561389U discloses a soil testing dissolution device, including a dissolution tank. The dissolution tank has a feed inlet at the top center. Inside the dissolution tank are a filter plate and a stirring assembly, with the filter plate located above the stirring assembly. Two receiving slots are located on either side of the top of the dissolution tank, each containing a disassembly assembly that cooperates with the filter plate. A water inlet pipe and a discharge pipe are located on one side of the dissolution tank, with the water inlet pipe located at the lower end of the filter plate. This utility model has the following advantages: by using the disassembly assembly, when the filter plate is clogged with small impurities, the disassembly assembly can be activated to disassemble the filter plate, facilitating the cleaning of impurities inside the filter plate and improving subsequent filtration.

A pull rod 13 is fixedly connected to the top of the filter plate 11. A cleaning mechanism 8 is provided on the rotating shaft 6. A connecting mechanism 9 is provided on the upper pull rod 13.

[0024] Please see Figure 1 , Figure 2 , Figure 4 The cleaning mechanism 8 includes a connecting sleeve 81. The left and right ends of the rotating shaft 6 are fixedly connected to the connecting sleeve 81. The connecting sleeve 82 is slidably sleeved inside the connecting sleeve 81. The outside of the connecting rod 82 is fixedly connected to the scraper 83. The scraper 83 is rotatably connected to the tank body 1. The connecting sleeve 81 is threadedly connected to the bolt 84. The bolt 84 is slidably connected to the connecting rod 82. The connecting sleeve 81 is slidably sleeved to the slider 85. The slider 85 is slidably connected to the connecting sleeve 81. The connecting sleeve 81 is equipped with a first spring 86. By designing the cleaning mechanism 8, it is convenient to clean the inner wall of the tank body 1.

[0025] Please see Figure 1 , Figure 2 , Figure 5 The connecting mechanism 9 includes a fixed seat 91 on the outer side of the pull rod 13, which is fixedly connected to the tank body 1. An insert block 92 is slidably fitted inside the fixed seat 91 and is slidably connected to the pull rod 13. A slot 93 is provided inside the pull rod 13, and the insert block 92 is slidably connected inside the slot 93. The slot 93 is designed so that the insert block 92 can slide inside the pull rod 13. A push rod 94 is fixedly connected to the top of the insert block 92 and is slidably connected to the fixed seat 91.

[0026] The specific implementation process of this utility model is as follows: When in use, soil is added into the interior of tank 1. Under the action of filter plate 11, the soil can be filtered and screened to remove impurities such as stones from the soil. During the filtration and screening process, motor 4 works simultaneously. The output end of motor 4 can drive the rotating shaft 6 to rotate. The rotating shaft 6 will drive the pusher 12 to rotate along the filter plate 11, which can push the material, accelerate the screening of the material, and also push the impurities to move, so as to avoid the impurities accumulating in one place and affecting the subsequent screening of the material.

[0027] After the soil is filtered and screened, a dissolving solution is added to the tank 1. Then, the motor 4 continues to work, and the rotation of the stirring rod 10 driven by the rotating shaft 6 can stir and dissolve the soil. During the stirring and dissolving process, the rotating shaft 6 can drive the connecting sleeve 81, the connecting rod 82 and the scraper 83 to rotate. As the scraper 83 rotates, it can scrape off the soil adhering to the inner wall of the tank 1, avoiding the problem of soil adhesion that is not easy to clean later. In addition, the first spring 86 inside the connecting sleeve 81 is in a compressed state, which will give the slider 85 an outward push, so that the scraper 83 can be pressed tightly against the inner wall of the tank 1, which can improve the scraping and cleaning effect.

[0028] When the filter plate 11 needs to be removed, push the push rod 94 directly. The push rod 94 drives the insert block 92 to move. The insert block 92 pushes the slide rod 95 to slide along the fixed rod 96 and squeeze the second spring 97. At the same time, the slide rod 95 will drive the magnetic block 98 to move. When the magnetic block 98 is attracted to the magnet 99, the insert block 92 will slide out from the slot 93. Then, pull up the pull rod 13 to remove the filter plate 11. At the same time, the filter plate 11 drives the rotating shaft 6 to move. The rotating shaft 6 will separate from the block 5, so that the stirring assembly can also be removed from the tank 1. This makes it easier to clean and maintain the filter plate 11 and the stirring assembly, and makes it more convenient to use.
