Description

Technical Field

[0001] The invention relates to the technical field of land management, and in particular to a mixing device for land management construction. Background Art

[0002] Land management refers to the process of applying engineering and biological measures to improve undesirable land characteristics, increase land utilization and productivity, and facilitate intensive management. The integrity of the land determines the comprehensiveness of land management measures.

[0003] Due to human activities, heavy metals such as cadmium, lead, zinc and chromium are continuously released into the environment and accumulated in the soil, resulting in a large amount of heavy metals in saline-alkali land. When humic acid is used to treat heavy metals in saline-alkali soil, the carboxyl, hydroxyl, carbonyl and amino groups in the humic acid can react with the heavy metals to form complexes and chelates, thereby reducing the content of water-soluble and exchangeable heavy metals in the soil. However, since the soil contains both heavy metals and alkalis, and the carboxyl, hydroxyl and amino groups are acidic, the acidic substances in the carboxyl, hydroxyl and amino groups will directly react with the alkali in the soil to neutralize the acid, causing the alkali in the soil and the carboxyl, hydroxyl and amino groups in the humic acid to disappear, resulting in the inability of humic acid to effectively treat the heavy metals in the soil, resulting in poor treatment effect on heavy metal soil.

[0050] It is worth noting that: an annular mounting member 14 is provided in the upper screening hollow tank 1, and a concave storage tray 1401 (the concave storage tray 1401 can store humic acid powder) is fixedly connected to the inner bottom end of the annular mounting member 14, and a conveying pipe 15 penetrating the annular mounting member 14 and the concave storage tray 1401 is provided in the annular mounting member 14, and micro electric push rods 1402 arranged opposite to each other are installed at the inner bottom end of the annular mounting member 14, and a connecting plate 1403 is fixedly connected between the two micro electric push rods 1402;

[0051] A circular groove which is plugged into the discharge pipe 11 is provided at the bottom end of the delivery pipe 15, and a threaded groove which extends from the top to the bottom and is connected to the inverted Y-shaped groove in the discharge pipe 11 is provided inside the delivery pipe 15 (the threaded groove allows the humic acid powder to slowly enter the discharge pipe 11, thereby ensuring that there is enough time to drain the water in the soil mixing barrel 9), and a plurality of columns are fixedly connected to the top end of the delivery pipe 15, and a connecting plate 1501 which is fixedly connected to the bottom end of the connecting plate 1403 is fixedly connected to the top end of the plurality of columns (the connecting plate 1501 and the delivery pipe 15 are driven downward by the micro-electric push rod 1402 and the connecting plate 1403, so that the humic acid powder in the concave storage plate 1401 enters the discharge pipe 11 through the threaded groove in the delivery pipe 15, and enters the soil mixing barrel 9).

[0052] A further benefit of adopting the above method is that the above device first reduces the alkalinity in the agglomerated soil and then treats the heavy metals in the soil, thereby avoiding the acid-base neutralization reaction between the acidic substances in the humic acid and the alkali in the soil, making the characteristics of the acid and the alkali disappear, thereby avoiding the inability of humic acid to treat the heavy metals in the soil and enhancing the treatment effect on the heavy metal soil.

[0053] The motor 7 is of prior art, and it can drive the output shaft to rotate, so no further details will be given here.

[0054] When the present invention is in use: when it is necessary to treat the soil containing heavy metals in the saline-alkali land, the staff first pours the mixed liquid of water and urea phosphate into the soil mixing barrel 9 so that it is located above the material collection ring 12, and pours humic acid into the lower mixing hollow tank 4, and then the staff installs the upper screening hollow tank 1 on the top of the lower mixing hollow tank 4, and plugs the conveying pipe 15 with the feeding pipe 11, installs the annular mounting part 14 in the middle of the upper screening hollow tank 1, and then pours humic acid powder into the lower concave storage tray 1401.

[0055] Then the staff starts the DC electric push rod 102, the electric telescopic rod 106 and the motor 7, so that the DC electric push rod 102 drives the moving ring 2 and the soil screening funnel 3 to vibrate up and down. Then the staff pours the soil into the soil screening funnel 3, so that the soil screening funnel 3 drives the soil to vibrate up and down, so that the uncaked soil (the uncaked soil indicates that it contains very little salt and alkali) moves down along the spiral groove in the soil screening funnel 3 during the continuous vibration process. The screen falls into the upper screening hollow tank 1 and then into the lower mixing hollow tank 4, while the agglomerated soil enters the soil chopping hollow tube 103 through the bottom end of the soil screening funnel 3. At this time, the electric telescopic rod 106 pushes the T-shaped plate 108 to move, thereby driving a plurality of soil chopping blades 107 arranged staggered with each other to move, and the agglomerated soil falling into the soil chopping hollow tube 103 is chopped. The chopped soil falls into the soil mixing barrel 9 through the soil screening ring 1031 and contacts with the liquid in the soil mixing barrel 9.

[0056] The motor 7 drives the gear 701 to rotate, and the gear 701 drives the gear ring 801 to rotate, thereby driving the turntable 8 to rotate, and the turntable 8 drives the plurality of soil stirring columns 802 and the plurality of electric heating rods 803 to rotate, and the soil stirring columns 802 are used to stir and mix the uncaked soil and humic acid in the lower mixing hollow tank 4, and at the same time, the electric heating rods 803 stir and mix the liquid (the liquid is a mixture of water and urea phosphate, and urea phosphate has full water solubility and low pH value, and these characteristics enable it to effectively improve the saline-alkali environment of the soil. By lowering the pH value of the soil, urea phosphate can activate beneficial elements in the soil, such as calcium, magnesium, iron, etc., which will release carbon dioxide and calcium, magnesium, iron, etc. when encountering the more acidic urea phosphate, thereby lowering the soil pH, improving the saline-alkali environment of the soil, activating soil activity, promoting crop growth, and effectively adjusting the pH value of the alkaline medium) and the chopped soil;

[0057] After a period of stirring and mixing, the liquid above the feeding ring 12 in the soil mixing barrel 9 and the agglomerated soil are fully mixed, so that the liquid can remove the alkali in the agglomerated soil, and at the same time, the humic acid in the lower mixing hollow tank 4 is fully mixed with the non-agglomerated soil to treat the heavy metals in the soil (humic acid contains active functional groups such as carboxyl, phenolic hydroxyl, methoxy, carbonyl, etc., with positive and negative charges, hydrogen bonds and free radicals, and can adsorb, passivate, oxidize and reduce, and chelate heavy metal ions in the soil to reduce the activity of heavy metals in the soil);

[0058] Then the staff turns off the motor 7 and starts the micro electric push rod 1402. The micro electric push rod 1402 drives the connecting plate 1403 to move downward, and drives the connecting disk 1501 and the conveying pipe 15 to move downward. When the conveying pipe 15 moves downward, it drives the feeding pipe 11 to move downward, thereby driving the sealing disk 1201 and the reset disk 13 to move downward, so that the water above the feeding ring 12 enters the upper part of the reset disk 13 through the hole in the middle of the feeding ring 12, and flows into the soil mixing barrel 9 and the space below the feeding ring 12 through the screen ring 1202, and then through the notch in the middle of the feeding ring 601 and the screen in the drainage groove set on the turntable 8, the water is discharged from the lower mixing hollow tank 4;

[0059] At the same time, the conveying pipe 15 moves downward, so that the humic acid powder in the concave storage disk 1401 enters the thread groove in the conveying pipe 15 through the space between the conveying pipe 15 and the connecting disk 1501, and slowly enters the inverted Y-shaped groove in the discharge pipe 11 through the thread groove, and finally enters above the material collection ring 12, and then the micro electric push rod 1402 is reset, so that the reset spring 1301 is reset and drives the reset disk 13, the discharge pipe 11 and the sealing disk 1201 to reset, and the hole in the middle of the material collection ring 12 is blocked;

[0060] Then the staff starts the motor 7 and the electric heating rod 803, so that the motor 7 drives the electric heating rod 803 to dry the soil above the feeding ring 12, and stirs the humic acid powder and the soil while drying, so that the humic acid powder and the soil above the feeding ring 12 that has lost its alkalinity are fully mixed, so as to achieve the treatment function of heavy metals in the soil;

[0061] After completing the heavy metal treatment of the soil, the staff holds the trapezoidal block 1101 and the feed pipe 11 and moves them upward, driving the feeding ring 12 to move upward while driving the feeding ring 601 and the feeding pipe 6 to move upward, thereby taking out the soil in the lower mixing hollow tank 4. The above-mentioned device first removes the alkali in the soil and then treats the heavy metals in the soil, thereby avoiding the acid-base neutralization reaction between the acidic substances in the humic acid and the alkali in the soil, making the characteristics of the acid and the alkali disappear, thereby avoiding the inability of humic acid to treat the heavy metals in the soil, and enhancing the treatment effect on the heavy metal soil.

[0062] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
