[0002] Heavy metal pollution is hidden, long-term, irreversible, difficult to control and has a long period of time. Heavy metal pollution not only leads to reduced crop yields, but also accumulates in the soil for a long time, causing serious damage to the soil ecosystem and groundwater, and even enters the food chain through plants, seriously threatening human health.

[0003] Magnetic sludge charcoal has magnetic absorption properties and strong adsorption effect on heavy metals. It can reduce the migration, transformation and ecological effects of heavy metals in the environment through fixation.

Magnetic sludge charcoal combines adsorption and catalytic properties and has a wide range of applications in the field of soil treatment.

[0004] In the existing technology of treating soil metals with magnetic sludge charcoal, the discharge port of the mixing barrel is small because the metal particles are large or the soil particles are not completely crushed, retaining large soil particles, which causes the discharge port to be blocked, making the cleaning work cumbersome and reducing the soil treatment efficiency.

[0024] The specific implementation of the present invention is described in detail below in conjunction with the accompanying drawings. It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0025] As mentioned above, the utility model provides a soil remediation device using magnetic biogas residue charcoal as a soil remediation agent, which is used to separate metal particles in the soil to achieve the effect of remediating the soil.

[0026] like Figure 1 As shown, the soil remediation device using magnetic biogas slag charcoal as a soil remediation agent includes a crushing bin 20 and an adsorption bin 30. The crushing bin 20 is provided with a crushing component, a screening component and a spray component in order from top to bottom, and the top and bottom of the crushing bin 20 are respectively provided with a No. 1 feed port 24 and a No. 1 discharge port 25, and the adsorption bin 30 is arranged below the crushing bin 20. A magnetic suction component is arranged in the adsorption bin 30, and the magnetic suction component is mainly used for adsorbing magnetic biogas slag charcoal for recycling. The top and bottom of the adsorption bin 30 are respectively provided with a No. 2 feed port 34 and a No. 2 discharge port 35, wherein the No. 1 discharge port 25 is connected to the No. 2 feed port 34, and the No. 1 discharge port 25 is arranged above the No. 2 feed port 34.

[0027] In the present invention, the magnetic biogas residue charcoal is biogas residue charcoal combined with Fe3+, and has adsorption and magnetic attraction properties. The magnetic biogas residue charcoal and the soil to be repaired are respectively put into the first inlet 11 and the second inlet 12, and then flow into the mixing funnel 10 at the same time, which is conducive to the full mixing of the magnetic biogas residue charcoal and the soil to be repaired. The bottom outlet of the mixing funnel 10 is preferably arranged above the crushing component to ensure that the soil can be fully crushed and fully mixed and contacted with the magnetic biogas residue charcoal. The mixed magnetic biogas residue charcoal and the soil to be repaired pass through the crushing component to reach the screening component. The large metal particles that are not broken are retained on the screening component, and the magnetic sludge charcoal, small metal particles and broken soil fall from the screening component to the No. 1 discharge port 25, and then fall into the adsorption bin 30 from the No. 1 discharge port 25 through the No. 2 feed port 34. The spray component will flush all the soil contaminated with the side wall of the crushing bin 20 to the No. 1 discharge port 25 and enter the adsorption bin 30. In the adsorption bin 30, the metal particles and the magnetic sludge charcoal with adsorbed metal particles are adsorbed on the magnetic suction component, and the soil water passes through the magnetic suction component and leaves the adsorption bin 30 from the No. 2 discharge port 35.

[0028] It should be noted that the crushing assembly is configured as a plurality of sets of rotating knife groups 21 installed at intervals, and two adjacent rotating knife groups 21 are staggered and cross-installed so as to be able to crush the soil as fully as possible and mix the soil and magnetic sludge charcoal so that the magnetic sludge charcoal and the soil are in full contact.

[0029] In the utility model, the screening component is configured as a detachable screen 22, and the screening component is preferably arranged below the crushing component. Magnetic sludge charcoal, small metal particles and soil are filtered out by the screen 22, and large metal particles are retained on the screen 22, thereby preventing large metal particles from clogging the inlet and outlet of the device.

[0030] Combination Figure 3 As shown, in one embodiment of the utility model, a positioning structure 27 is installed on the inner wall of the crushing bin 20 for installing and positioning the screen 22. Since the screen 22 is mainly used to retain large metal particles, as the soil remediation treatment proceeds, more large metal particles will accumulate on the screen 22. Therefore, the screen 22 is configured to be detachable in the crushing bin 20. The screen 22 can be installed and removed by putting it on or removing it from the positioning structure 27, which is convenient for cleaning.

[0031] In the present invention, the aperture of the screen 22 is 0.15 mm to 1.00 mm, in order to block large metal particles while allowing magnetic biogas slag charcoal and soil to pass through the screen 22 .

[0032] In one embodiment of the utility model, the spray assembly is configured as a plurality of spray head groups 23 connected to an external water source. The spray assembly is preferably disposed below the screen 22. The spray head group 23 will flush the magnetic sludge charcoal, small metal particles and soil passing through the screen 22 to avoid sticking to the side wall of the crushing bin 20. At the same time, force is applied to the magnetic sludge charcoal, small metal particles and soil near the No. 1 discharge port 25, which is conducive to their outflow from the No. 1 discharge port 25 and reduces blockage.

[0033] In the utility model, the magnetic suction component is configured as a detachably mounted stirring mesh 33. The stirring mesh 33 has a magnet component and also has an adsorption effect on small metal particles, which supplements the adsorption effect of the magnetic sludge charcoal on small metal particles. The magnetic sludge charcoal, small metal particles and soil water enter the adsorption bin 30 from the No. 2 feed port 35. The magnetic sludge charcoal adsorbs the metal particles in the soil and is adsorbed on the stirring mesh 33 at the same time. The soil water filters through the stirring mesh 33 and leaves the adsorption bin 30 from the No. 2 discharge port 34. As the repair treatment proceeds, the magnetic sludge charcoal that adsorbs the metal particles gathers on the stirring mesh 33. The stirring mesh 33 is then removed from the adsorption bin 30, cleaned and put back into the adsorption bin 30 for work.

[0034] In the utility model, the top of the adsorption bin 30 is connected to a medicine barrel 31 for adding other repairing liquids to carry out subsequent repair of the soil, which is convenient and faster to make the soil water and the repairing liquid contact evenly under the action of the stirring mesh 33.

[0035] Combination Figure 2 As shown, in one embodiment of the utility model, the crushing bin 20 and the adsorption bin 30 are respectively provided with a detachable No. 1 side cover 26 and No. 2 side cover 37, which is mainly convenient for cleaning and repairing the internal component structure of the crushing bin 20 and the adsorption bin 30. When using the device, the No. 1 side cover 26 and the No. 2 side cover 37 are installed on the crushing bin 20 and the adsorption bin 30, and removed for cleaning.

[0036] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto. Within the technical concept of the present invention, the technical solution of the present invention can be subjected to a variety of simple modifications. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations. However, these simple modifications and combinations should also be regarded as the contents disclosed by the present invention and belong to the protection scope of the present invention.
