The rotating shaft 5 is vertically rotatably installed inside the main chamber. Six dissolving cylinders 6 are connected in a ring array around the circumference of the rotating shaft 5. The rotating shaft 5 is connected to a motor 7. Multiple nozzles 11 are arranged at the top of the main chamber. A return port is arranged at the bottom of the main chamber. The return port is connected to a return pipe 17 through a return pump 16. The nozzles 11 are connected to a distribution ring pipe 12. The distribution ring pipe 12 is connected to an inlet pipe 13. The inlet pipe 13 is connected to a storage container for the dissolving liquid 23. An inlet pump is arranged on the inlet pipe 13. The return pipe 17 is connected to the distribution ring pipe 12. An ultrasonic generator 18 and an electric heating plate 19 are arranged inside the main chamber. A seepage hole 20 is arranged at the top of the dissolving cylinder 6. A movable chamber door 4 is hinged to the side wall of the main chamber.

[0023] In this embodiment, a connecting sleeve 8 is fixedly connected to the rotating shaft 5. Multiple crossbars are connected in a ring array around the periphery of the connecting sleeve 8. A collar 9 is fixedly connected to each crossbar and fitted onto the side wall of the dissolving cylinder 6. A stopper plate is detachably fastened to the top of the dissolving cylinder 6. Multiple seepage holes 20 are equidistantly provided on the stopper plate. A cylinder cap 10 is threadedly connected to the bottom of the dissolving cylinder 6. A separating mesh plate 21 for separating the soil sample 22 and the dissolving liquid 23 is fixedly installed inside the dissolving cylinder 6. The mesh diameter of the separating mesh plate 21 is smaller than the particle size of the soil sample 22. The dissolving liquid 23 is slowly seeped into the soil sample 22 by top spraying, allowing for simultaneous addition and centrifugal mixing.

[0024] In this embodiment, the main compartment includes an outer compartment 1 and an inner compartment 2. A thermal insulation layer 3 is provided between the outer compartment 1 and the inner compartment 2. The return liquid pipe 17, the liquid distribution ring pipe 12, and the return liquid pump 16 are arranged inside the thermal insulation layer 3. An inlet valve 14 is provided on the inlet pipe 13. A return liquid port is opened on the inner bottom surface of the inner compartment 2. The return liquid port is connected to the inlet end of the return liquid pump 16. A screen is provided on the return liquid port.

[0025] In this embodiment, the rotating shaft 5 is rotatably installed in the main chamber via the bearing 15. The top of the rotating shaft 5 extends out of the main chamber and is connected to the output shaft of the motor 7. A transparent window is provided on the movable chamber door 4. The dissolving cylinder 6 is made of transparent material and is provided with scale lines. The amount of dissolving liquid 23 in the dissolving cylinder 6 is controlled by the scale lines to meet the preset ratio of soil sample 22 to dissolving liquid 23.

[0026] In this embodiment, a vent pipe is installed at the bottom of the main chamber, and a vent valve is installed on the vent pipe. The vent pipe is connected to a waste liquid collection container. When the amount of dissolved liquid injected reaches the standard, the return pump is turned off and the dissolved liquid in the main chamber is emptied through the vent valve.

[0027] In this embodiment, a boss ring is provided on the side wall of the dissolving cylinder 6 to engage with the collar 9.

[0028] In use, the required amount of soil sample 22 is evenly distributed into multiple dissolving cylinders 6. After filling with soil sample 22, the cylinder cap 10 is tightened and flipped to lock onto the collar 9. The liquid level after adding dissolving solution 23 is determined according to the amount of soil sample 22 in the dissolving cylinder 6. The dissolving solution 23 is evenly sprayed into the inner chamber 2 through the nozzle 11. The dissolving solution 23 flows into the soil sample 22 through the seepage hole 20. Then, the motor 7 is turned on to rotate slowly, causing the multiple dissolving cylinders 6 to rotate and generate centrifugal force to achieve a preliminary stirring effect. At the same time, the ultrasonic generator 18 and the electric heating plate 19 are turned on. The dissolving solution 23 collected at the bottom of the inner chamber 2 flows back into the distribution ring pipe 12 through the return pump 16 to complete continuous circulation. When the liquid level in the dissolving cylinder 6 reaches the preset liquid level, the return pump 16 and the inlet valve 14 are turned off. The power of the motor 7 is increased to increase the speed and centrifugal force to improve the stirring effect. The degree of dissolution is judged by observing the uniformity of solution color, solution transparency, or the state of solution particle precipitation through the transparent window. After the standard is met, the dissolving cylinder 6 is removed and the dissolving solution 23 is tested by the instrument.

[0029] After a single use, clean water is injected into the inlet pipe 13 and the return pump 16 is turned on to clean the pipe and the inner chamber 2 to avoid cross-contamination.
