Description
Technical Field
[0001] The utility model belongs to the technical field of soil pollution control, and in particular relates to a contaminated soil restoration and control device. Background Art
[0002] Soil pollutants can be roughly divided into two categories: inorganic pollutants and organic pollutants. When the soil contains too many harmful substances, which exceed the self-purification capacity of the soil, it will cause changes in the composition, structure and function of the soil, and the activity of microorganisms will be inhibited. Harmful substances or their decomposition products will gradually accumulate in the soil through "soil → plant → human body" or "soil → water → human body" and be indirectly absorbed by the human body to the extent that it endangers human health. This is soil pollution. One way to repair soil pollution is to use a repair fluid to fully mix the repair fluid and the soil. Now, the soil is generally manually fed into the feeding auger and then into the mixing unit. This has high labor intensity and low repair efficiency.
[0003] In the prior art, a Chinese patent with a reference publication number of CN 111530907 B discloses a hand-push contaminated soil restoration and environmental protection treatment device, comprising a trolley, a mixing unit for mixing soil with a repair liquid installed on the trolley, and a feeding unit for supplying soil to the mixing unit, wherein the output port of the feeding unit is connected to the feed port of the mixing unit, and a discharge pipe is installed at the bottom of the mixing unit. The feeding unit comprises a waist-shaped mounting shell, a hydraulic rod, a conveyor belt assembly, a lifting plate, a shovel plate, an electric push rod and a soil rake. The utility model sprays the repair liquid on the soil, mixes it fully, and the soil mixed with the spray liquid is discharged from the discharge pipe and falls back to the ground, completing the repair, with a high degree of automation, high repair efficiency and good effect.
[0004] The comparative document provides a hand-pushed contaminated soil resetting and environmental protection management device, but the above patent requires a soil lifting device to transport the soil upward and then stir it for repair, which requires a lot of equipment and causes a complex structure.

[0024] It should be noted that, since the existing contaminated soil restoration and treatment devices require a soil lifting device to transport the soil upward for mixing and repair, a lot of equipment is required, resulting in a complex structure. In this embodiment, the soil shoveling component 3 can directly transport the soil to the interior of the inner mixing box 41 for soil repair during the movement of the device. There is no need to set up a separate soil lifting device, and the structure is simpler. The high-speed rotation of the first stirring paddle 45, the second stirring paddle 47 and the third stirring paddle 49 can achieve repeated breaking up of the soil while fully mixing the soil repair liquid with the soil, ensuring that the soil and the soil repair liquid are evenly stirred, thereby improving the effect of soil repair and achieving soil restoration and treatment.
[0025] Specifically, in this embodiment, the scheme mainly includes a shoveling component 3 and a stirring and mixing component 4. When in use, a groove is dug on the soil, the device is placed above the soil, and the drum 32 is located in the groove. When the soil is restored and treated, the handle 5 is held and the device is pushed by the rotation of the walking wheel 2. The first motor 31 drives the drum 32 to rotate through the output end on one side thereof, and the scraper 33 and the crushing knife 34 on the drum 32 rotate synchronously. After the crushing knife 34 contacts the soil, the soil is cut. After that, after the scraper 33 contacts the soil, the scraper 33 scrapes the cut soil upwards. Under the cover of the arc-shaped protective cover 35, the scraper 33 sweeps the soil toward the inside of the outer shell 1. Under the action of centrifugal force, the soil passes through the feed port 42 and enters the inner mixing box 41. The liquid pump 7 repairs the soil. The soil remediation liquid in the re-liquid storage box 6 is pumped into the connecting pipe 8. Under the guidance of the connecting pipe 8, the soil remediation liquid enters the nozzle 10 under the diversion of the diversion pipe 9. The nozzle 10 sprays the soil remediation liquid into the inner mixing box 41. The second motor 44 drives the first stirring paddle 45 to rotate at high speed through the output end on one side thereof. The third motor 46 drives the second stirring paddle 47 to rotate at high speed through the output end on one side thereof. The fourth motor 48 drives the third stirring paddle 49 to rotate at high speed through the output end on one side thereof. The first stirring paddle 45, the second stirring paddle 47 and the third stirring paddle 49 break up the soil while fully mixing the soil remediation liquid with the soil to ensure that the soil and the soil remediation liquid are evenly mixed. The repaired soil is discharged into the groove left after the device moves forward through the discharge port 43 to achieve soil return, thereby achieving soil restoration and treatment.
[0026] In a further preferred embodiment of the present invention, Figure 1-2 As shown, there are six scrapers 33 in total, and the six scrapers 33 are symmetrically arranged on the outer wall of the drum 32, the outer wall of the scraper 33 and the inner wall of the arc-shaped protective cover 35 are in contact with each other, and the cross-section of the crushing knife 34 is an isosceles triangle structure.
[0027] In this embodiment, the soil blocks are first cut by the crushing blade 34 to facilitate the scraping of the soil, thereby realizing the collection of the soil.
[0028] In a further preferred embodiment of the present invention, Figure 1 As shown, the repair liquid storage box 6 and the input end of the liquid pump 7 are connected through a pipeline, and the bottom end of the pipeline is located at a lower position inside the repair liquid storage box 6.
[0029] In this embodiment, soil restoration and treatment can be achieved through the soil restoration liquid inside the restoration liquid storage box 6.
