Description

Technical Field

[0001] The utility model relates to the technical field of soil restoration, in particular to a soil ecological restoration device with high efficiency and ventilation. Background Art

[0002] Soil ecological restoration refers to the process of repairing and restoring soil using a combination of physical, chemical, and biological engineering measures and technologies. This process rapidly degrades and transforms pollutants trapped in the soil, restoring the soil's natural functions. Through soil ecological restoration, soil quality and health can be restored and improved, thereby protecting the ecological environment and promoting sustainable development.

[0003] Soil ecological restoration can be divided into two phases: first, soil conservation, which involves controlling soil loss within acceptable limits through engineering or biological measures; and second, soil improvement, which involves increasing soil organic matter and nutrient content to improve soil properties and fertility. However, existing soil ecological restoration devices suffer from poor ventilation during soil improvement, preventing pollutants from being efficiently discharged as gases, which in turn affects the efficiency and effectiveness of soil ecological restoration.

[0004] Therefore, there is an urgent need to redesign a new, efficient and ventilated soil ecological restoration device to solve the above problems. Utility Model Content

[0032] References to "embodiments" herein mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present invention. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0033] See also Figures 1 to 8 The utility model provides a highly efficient and ventilated soil ecological restoration device comprising a restoration chamber 1 and an air injection mechanism 2.

[0034] The repair chamber 1 is connected to a feeding port 101 and a discharging port 102. Soil is added to the repair chamber 1 through the feeding port 101 and then discharged through the discharging port 102. The feeding port 101 and the discharging port 102 are separated from each other, and the feeding port 101 is close to the motor 104, which prolongs the repair time of the soil in the repair chamber 1 and ensures the repair effect of the soil.

[0035] In addition, a sealing cover with a handle is installed on the feeding port 101. When soil remediation is being performed, the sealing cover is placed on the feeding port 101, making the interior of the remediation chamber 1 a relatively closed space. Gas in the remediation chamber 1 is not easily discharged through the feeding port 101, but is discharged through the return pipe 205, allowing the gas to be filtered and reused. A control valve is installed on the discharge port 102 to control the opening and closing of the discharge port 102.

[0036] Specifically, a mounting plate 103 is fixedly connected to the side wall of the repair chamber 1, and a motor 104 is mounted on the mounting plate 103. A rotating shaft 105 is connected to the motor 104. One end of the rotating shaft 105 located inside the repair chamber 1 is connected to an auger blade 106 and a plurality of air injection pipes 109. When the motor 104 is running, the motor 104 can drive the rotating shaft 105 and the auger blade 106 to rotate. The rotation of the auger blade 106 can stir the soil in the repair chamber 1, thereby improving the ventilation effect of the soil and thus improving the soil remediation effect.

[0037] Preferably, the auger blades 106 and the air jet pipe 109 are staggered with each other, and the air jet pipe 109 is installed on the rotating shaft 105 at an angle, that is, Figure 5 The state shown makes it difficult for the soil in the remediation chamber 1 to enter the air injection pipe 109, thereby reducing the probability of the air injection pipe 109 being blocked by the soil and ensuring the normal ventilation effect of the air injection pipe 109. At the same time, the gas discharged from the air injection pipe 109 can fully contact the soil, thereby improving the removal effect of soil pollutants.

[0038] Optionally, the inclination angle of the air jet pipe 109 ranges from 15 to 30 degrees. Preferably, the inclination angle of the air jet pipe 109 is 20 degrees. By installing the air jet pipe 109 at an angle, soil is not easily able to enter the air jet pipe 109, thereby ensuring the normal ventilation effect of the air jet pipe 109.

[0039] In addition, a retaining net is installed in the air injection pipe 109 to further reduce the probability of soil entering the air injection pipe 109.

[0040] See also Figures 1 to 8 A cavity 107 is provided in the rotating shaft 105, and a plurality of air inlet holes 108 are provided on the side wall of the rotating shaft 105 outside the repair chamber 1. The cavity 107 and the air inlet holes 108 are connected with the injection pipe 109. The gas enters the cavity 107 through the air inlet holes 108 and is then discharged outward through the plurality of injection pipes 109, so that the gas can fully contact with the soil, which not only improves the ventilation effect of the soil, but also allows the pollutants in the soil to be quickly discharged in the form of gas, thereby improving the efficiency and effect of soil ecological restoration.

[0041] See also Figures 1 to 8 The gas injection mechanism 2 is installed on the mounting plate 103. The gas injection mechanism 2 is used to inject gas into the soil in the repair chamber 1 to improve the ventilation effect of the soil, thereby realizing soil repair.

[0042] The gas injection mechanism 2 includes an air pump 201 , and the air pump 201 is connected to an air delivery pipe 202 . The air pump 201 extracts external gas and delivers it through the air delivery pipe 202 .

[0043] Preferably, the gas pipe 202 is made of a heat-conducting material, and a heating wire is installed on the outside of the gas pipe 202. When the heating wire is running, the heating wire can instantly heat the gas transported in the gas pipe 202, thereby increasing the temperature of the gas entering the remediation chamber 1, causing pollutants in the soil to be heated and evaporated into gas, thereby improving the efficiency and effect of soil ecological remediation.

[0044] In addition, a protective cover 204 is provided on the outside of the heating wire to protect the heating wire so that the heating wire is not likely to burn the staff.

[0045] See also Figures 1 to 8 A hollow sleeve 203 is connected to the gas pipe 202, and the hollow sleeve 203 is rotatably connected to the rotating shaft 105. A fixing rod is connected between the hollow sleeve 203 and the mounting plate 103, so that the hollow sleeve 203 is not easy to rotate with the rotating shaft 105 to facilitate gas injection.

[0046] Preferably, the hollow sleeve 203 is disposed outside the rotating shaft 105 and wraps around the air inlet 108 .

[0047] The repair chamber 1 is connected to a return air pipe 205, one end of which is connected to the interior of the repair chamber 1, and the other end of which is connected to the air inlet of the air pump 201. One end of the return air pipe 205 located inside the repair chamber 1 is connected to a gas collecting hood 206. The gas in the repair chamber 1 can be re-absorbed by the air pump 201 through the return air pipe 205, so that the heat in the gas can be reused, and the direct discharge of pollutants in the gas can also be reduced.

[0048] Preferably, a heat-insulating material is provided on the outside of the return air pipe 205 so that heat is not easily lost when the gas flows in the return air pipe 205 .

[0049] In addition, a filter box 207 is installed on the return air pipe 205, and a grid frame 208 and a pair of filter screens 210 are installed in the filter box 207.

[0050] Specifically, a filter bag 209 is mounted on the grid 208. The filter bag 209 is used to filter dirt from the gas, preventing it from affecting the air pump 201. An activated carbon layer 211 is provided between a pair of filters 210. The activated carbon layer 211 can absorb pollutants from the gas, preventing them from re-entering the remediation chamber 1, thereby ensuring the soil remediation effect.

[0051] Preferably, the filter bag 209 and the activated carbon layer 211 are both commercially available products and can be purchased and used directly.

[0052] In addition, a cover door is hingedly connected to the side wall of the filter box 207 to facilitate cleaning or replacement of the filter bag 209 and replenishment of the activated carbon layer 211.

[0053] During use, the motor 104 is operated to rotate the shaft 105 and the auger blades 106. The soil to be repaired is placed into the repair chamber 1 through the feeding port 101, and the discharge port 102 is closed. The soil is turned over by the rotating auger blades 106, thereby increasing the looseness of the soil and allowing the soil to be breathed.

[0054] The air pump 201 and heating wire operate. The air pump 201 draws in ambient air and delivers it through the air pipe 202. When the heating wire operates, it instantly heats the air flowing within the air pipe 202, raising its temperature. The heated air enters the hollow sleeve 203, then enters the cavity 107 through the plurality of air inlet holes 108, and is discharged into the soil through the plurality of air jets 109. The heated air evaporates pollutants in the soil, effectively removing them and significantly improving soil ventilation.

[0055] Because the return air pipe 205 is connected to the air inlet of the air pump 201, a negative pressure state is formed in the return air pipe 205. The air in the repair chamber 1 is sucked into the return air pipe 205 and enters the filter box 207. The filter bag 209 removes dirt from the air, and the activated carbon layer 211 removes pollutants from the air. The air is then sucked back into the repair chamber 1 by the air pump 201. This cycle repeats, allowing the heat in the air to be reused.

[0056] When the soil remediation is completed, the heating wire and the air pump 201 are stopped, and the control valve on the discharge port 102 is opened to discharge the soil.

[0057] The above description is only an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
