Description

Technical Field

[0001] The present invention relates to the field of environmental protection, and in particular to a soil remediation device. Background Art

[0002] With the rapid development of my country's economy and the acceleration of urbanization and industrialization, soil and groundwater pollution problems are becoming increasingly prominent. During industrial production, due to improper operation or management, a large amount of pollutants enter the surrounding environment, causing serious pollution. Abandoned chemical contaminated sites often occupy valuable urban locations. Before these lands can be reused for agricultural or commercial purposes, the contaminated soil of the original industrial abandoned sites must be remediated.

[0003] Regarding patents on soil remediation devices, after searching, publication number CN207254918U discloses a soil remediation device, which includes a chemical elution kettle, the chemical elution kettle including a stirring motor, a stirring shaft and a stirring paddle. The side wall of the chemical elution kettle is provided with a first inlet and a second inlet for respectively supplying soil and soil remediation liquid into the chemical elution kettle. The chemical elution kettle is connected to a screw conveying mechanism, which includes a cylinder, an auger rotatably arranged in the cylinder, and a drive assembly for driving the auger to rotate. The cylinder is connected to the bottom of the chemical elution kettle through a pipeline, and a hot air inlet and a hot air outlet are respectively provided on the cylinder. The hot air inlet is connected to a hot air blower through a pipeline. A discharge port for discharging soil is provided on the side of the cylinder facing away from the chemical elution kettle.

[0004] Although the above-mentioned device can drive the auger to rotate continuously through the reducer after the conveying motor is started, and drive the mud to be fed forward along the cylinder; in this process, the hot air from the hot air blower enters the heat source cavity through the hot air inlet, and is discharged from the heat source cavity through the hot air outlet under the guidance of the induced draft fan; the hot air entering the heat source cavity makes the heat source cavity as a whole constitute a heat source for heating the mud, so that the moisture in the mud continues to evaporate; finally, the steam is discharged from the inner cylinder through the exhaust port, and the dry soil is discharged from the discharge port, but in actual use, when the soil is transported inside the spiral conveying mechanism and is dried by the hot air and discharged, the soil is prone to compaction inside the spiral conveying mechanism. The compacted soil will have the problem of "dry outside and wet inside": the hot air can only dry the surface of the compacted lumps, and the interior is wrapped by the hard outer layer, and the moisture is difficult to evaporate, resulting in incomplete drying.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. This application forms a distributed hot air injection system through a drying tube and multiple groups of air jets. A large number of air holes evenly release hot air, increasing the contact area with the soil and accelerating water evaporation and pollutant volatilization. The material-turning blades of the disturbance scraper mechanism prevent soil from adhering to the tube wall and further break up soil clods, improving the drying effect and extending the service life of the equipment. The design of the connecting plates A and B facilitates equipment assembly and maintenance. The filter cartridge and its accessories effectively separate dust and ensure stable system operation. The hot air recycling design reduces energy consumption. The combination of wire mesh and support bars can evenly distribute airflow and improve thermal energy utilization. The outer surface of the air jet is wrapped with wire mesh to prevent soil from blocking the air holes.

[0018] 2. This application uses a material turning piece to turn the material inside the repair cylinder. The sharpened end simultaneously breaks up lumps during transportation, eliminating the need for additional pre-treatment equipment, simplifying the process and reducing investment costs. The application also enhances heat and mass transfer efficiency, increasing the specific surface area of ​​the crushed small particles, allowing the high-temperature gas to more fully contact the material. By crushing the compacted soil, thorough drying is achieved, improving the drying rate and uniformity, and reducing the risk of local overheating. The dynamic crushing function prevents large pieces of material from clogging the pipeline or accumulating in dead corners of the equipment during transportation, ensuring continuous and stable operation of the system.

[0019] 3. This application further mixes the agent and soil through the turning action of the turning piece, and continuously exposes the partially dried material to the hot air flow, ensuring that the remediation reaction proceeds fully. Uniform drying reduces energy waste, shortens the drying time required for the crushed material, and reduces overall energy consumption. The crushing and turning functions reduce the wear of the material on the cylinder wall, which can extend the service life of the equipment by more than 30%. The improved uniformity of the material particle size helps to ensure the consistency of the physical and chemical properties of the remediated soil and meet the standards for subsequent resource utilization. This integrated design of conveying, crushing, drying and turning, through the deep coupling of mechanical and thermal effects, significantly improves the treatment efficiency and economic efficiency of the soil remediation system.

[0020] 4. This application allows large pieces of soil to be collected and then re-entered into the repair barrel for repair and drying. Small pieces and powdery soil can pass through the discharge space and be quickly collected by the collection bucket. After the filter cartridge is used, the handle can be used to make the impurity removal seat move linearly with the isolation column as the track, and the material inside the discharge space can be removed through multiple sets of pointed columns; the material stuck in the discharge space can be quickly cleaned; the discharge space formed by the isolation column can achieve particle size classification, and large pieces of material automatically flow back to the repair barrel, ensuring that all soil meets the target treatment standard and improving product quality stability;

[0021] 5. This application uses a tip-column linear cleaning mechanism driven by a handheld handle to complete the unclogging of the filter cartridge within 3-5 minutes, greatly improving operation and maintenance efficiency; the isolation column serves as both a filter medium support structure and a cleaning track, simplifying the mechanical design; the baffle and extension plate of the collection bucket ensure directional flow of materials and reduce secondary pollution; through mechanical structure innovation, it solves the common problem of screen clogging in soil remediation, achieves a balance between efficient operation of the equipment and low maintenance costs, and is particularly suitable for remediation projects with high mud content or clay soils; by adjusting the spacing between isolation columns, it can flexibly adapt to different soil particle size requirements; mechanical screening is combined with the principle of centrifugal separation, and through geometric structure innovation, the filtration efficiency, equipment life and maintainability are improved, which is particularly suitable for scenarios with strict requirements on particle classification in soil remediation projects.
