Description

Technical Field

[0001] The utility model relates to the technical field of soil remediation, in particular to a construction waste soil remediation device. Background Art

[0002] Construction waste refers to waste generated during the construction, renovation, expansion, demolition, renovation, and decoration of buildings. This waste includes materials such as used bricks, stones, concrete blocks, scrap metal, wood, plastic, and paper. Construction waste not only consumes significant land resources and impacts the aesthetics of the environment, but can also pose a threat to the environment and human health. When construction waste is mixed with soil, the resulting mixture may contain harmful chemicals, heavy metals, or other contaminants that can negatively impact soil structure, fertility, and biological activity. Therefore, soil remediation equipment is necessary to properly treat and remediate this soil. Soil remediation equipment is a device and technical system used to remediate contaminated soil. Its primary function is to remove or reduce soil contaminants through physical, chemical, or biological methods, restoring the soil to its original healthy state. Soil remediation equipment can effectively remove or degrade harmful substances, preventing harm to the environment and human health. It can also transform some soil into a reusable resource. For example, remediated soil can be used for landscaping, road filling, and other applications, reducing the extraction and consumption of natural resources.

[0003] When using a soil remediation device to repair construction waste soil, it is usually necessary to crush the construction waste soil and subject the crushed construction waste soil to a chemical reaction to achieve remediation. Since the construction waste soil may contain some large waste and debris, such as concrete blocks or plastics, as well as some small impurities, such as small gravel blocks and brick blocks, etc., during the remediation process, the construction waste soil cannot be well screened and the waste, debris and impurities contained therein cannot be intercepted and processed, so that these waste, debris and impurities will react with the construction waste soil, thereby reducing the remediation ability and affecting the remediation quality. Therefore, in order to solve the above problems, a construction waste soil remediation device is proposed. Summary of the Invention

The first motor 13 is operated to cause the first rotating rod 12 to drive the crushing knife 14 to rotate, so that the soil can be crushed by the crushing knife 14, making the soil more finely divided and avoiding soil caking. The repair agent in the storage box 15 is extracted by the water pump 16 and sprayed on the soil through the nozzle 17, so that the pollutants in the soil can undergo a chemical reaction and then be converted into harmless substances, thereby achieving soil repair.

[0024] A screening mechanism is provided on the inner side of the repair box 1, and the screening mechanism includes a screening bin 2, which is opened on the inner side of the repair box 1, and a first spiral conveying rod 21 is movably connected to the inner side of the screening bin 2, and the first spiral conveying rod 21 and the repair box 1 are movably connected. A second motor 22 is fixedly installed on the surface of the repair box 1, and the output ends of the first spiral conveying rod 21 and the second motor 22 are fixedly connected. A filter screen 23 is fixedly connected to the bottom end of the screening bin 2, and a first debris row port 24 is opened on the inner side of the repair box 1, and a filter plate 25 is movably connected to the inner side of the repair box 1. Through the setting of the first spiral conveying rod 21, soil can be transported. During the transportation process, the soil can fall through the filter screen 23, and the waste and debris in the soil will be intercepted by the filter screen 23 and discharged through the first debris row port 24, which can prevent waste and debris from entering the repair box 1 and being crushed and reacted, thereby ensuring the quality of the soil and the repair effect.

[0025] Furthermore, the screening mechanism includes a second rotating rod 26, which is movably connected to the inner side of the repair box 1, and a cam 27 is fixedly connected to the surface of the second rotating rod 26. A third motor 28 is fixedly installed on the surface of the repair box 1, and a fixed plate 29 is fixedly connected to the inner wall of the repair box 1. The lower surface of the fixed plate 29 is fixedly connected to a spring 210.

[0027] Furthermore, one end of the spring 210 is fixedly connected to the filter plate 25, and the other end of the spring 210 is fixedly connected to the fixed plate 29. Through the setting of the spring 210, when the cam 27 cancels the squeezing of the filter plate 25, the filter plate 25 can be reset.

[0028] Furthermore, a mixing mechanism is provided on the inner side of the repair box 1, and the mixing mechanism includes a connecting block 3, which is fixedly connected to the inner wall of the repair box 1, and a third rotating rod 31 is movably connected to the inner side of the connecting block 3, and a fourth motor 32 is fixedly installed on the inner side of the connecting block 3. A stirring rod 33 is fixedly connected to the surface of the third rotating rod 31, and a second spiral conveying rod 34 is fixedly connected to the bottom end of the third rotating rod 31. The third rotating rod 31 is driven to rotate by the operation of the fourth motor 32, so that the stirring rod 33 can be rotated to mix the soil and the repair agent, so that the repair agent is more uniform in the soil, which can ensure the repair effect.

[0030] Working principle: When in use, the second motor 22 is electrically connected to an external power source, and the staff starts the second motor 22 by pressing the switch. The operation of the second motor 22 drives the first screw conveying rod 21 to rotate. The first screw conveying rod 21 can convey the soil entering the screening bin 2. The soil will be screened when passing through the filter 23, and the sundries and waste in the soil will be intercepted by the filter 23 and discharged through the first impurity discharge port 24. The soil falls through the filter 23, and the filter plate 25 can perform secondary screening on the fallen soil, so as to intercept small impurities in the soil and discharge them through the second impurity discharge port 211. The impurities discharged through the second impurity discharge port 211 may contain some soil that has not been completely crushed.

The third motor 28 is electrically connected to the external power supply. The staff starts the third motor 28 by pressing the switch. The operation of the third motor 28 drives the second rotating rod 26 to rotate. The cam 27 rotates accordingly under the action of the second rotating rod 26. When the cam 27 rotates, it squeezes the filter plate 25, which will enable the filter plate 25 to move upward. At this time, the spring 210 is in a contracted state. When the cam 27 cancels the squeezing of the filter plate 25 during the rotation process, the filter plate 25 is reset under the action of the spring 210. Then, through the cooperation of the cam 27 and the spring 210, the filter plate 25 can reciprocate and vibrate, thereby improving the screening efficiency and preventing the filter plate 25 from being blocked.

[0031] The fourth motor 32 is electrically connected to an external power supply. The staff starts the fourth motor 32 by pressing the switch. The operation of the fourth motor 32 drives the third rotating rod 31 to rotate. The stirring rod 33 and the second spiral conveying rod 34 will rotate accordingly under the action of the third rotating rod 31. The rotation of the stirring rod 33 can mix the soil and the repair liquid, so that the repair liquid can be more uniform, thereby achieving better repair. The second spiral conveying rod 34 can transport the soil to facilitate stable discharge of the soil.
