Description

Technical Field

[0001] The present invention relates to the technical field related to soil remediation, and in particular to a device for remediating soil contaminated by mine geology. Background Art

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in the soil, so that their concentration is reduced to an acceptable level, or to transform toxic and harmful pollutants into harmless substances, thereby achieving the purpose of soil remediation. Physical methods include heat treatment, engineering measures, electric remediation, filling and soil covering, etc. Chemical methods are to repair contaminated soil by regulating the mobility of heavy metals in the soil through chemical reactions, using chemical reagents to regulate or reduce the concentration, solubility, and freedom of heavy metals, increase the content of soil organic matter, and then change the electrolysis of the soil. Biological methods use plants grown naturally or cultivated by genetic engineering to reduce the content of heavy metals in the soil, simultaneously improve soil nutrient conditions and restore its functions, and promote microenvironment optimization.

[0003] Publication No. CN115647018A discloses a mine geological contaminated soil remediation device, which belongs to the field of soil remediation technology, including a vehicle body and a storage box, a storage box is arranged on the left side wall of the top of the vehicle body, a mounting frame is installed on the right side wall of the top of the vehicle body, a mounting plate is slidably installed on the inner cavity of the mounting frame, an electric push rod is installed on the top wall of the mounting frame, the electric push rod extends to the inner cavity of the mounting frame and is connected to the top wall of the mounting plate, holes are evenly opened on the mounting plate, injection pipes are inserted in the holes, and the inner cavity of the injection pipe is connected with the inner cavity of the storage box through a conduit; a protective sleeve is sleeved on the bottom of the outer wall of the injection pipe, and liquid outlets are evenly opened on the bottom of the outer wall of the injection pipe, and the liquid outlets are located in the inner cavity of the protective sleeve, the injection pipe will not directly contact with the soil, so as to avoid soil entering into the liquid outlet of the injection pipe and clogging of the liquid outlet of the injection pipe, so as to ensure that the repair liquid is normally injected into the soil and the quality of soil remediation is ensured.

[0004] The existing mine geological contaminated soil remediation device injects soil remediation liquid into the soil through an injection pipe. However, the injection holes opened during the injection process are easily blocked by the soil, thus affecting the injection speed. When using this method, the state of the soil itself needs to be considered. For areas with high soil density, the soil remediation liquid is easy to accumulate near the holes after injection and is not easy to spread, thus affecting the soil remediation effect and easily causing waste. Summary of the invention

[0008] When in use, the clods in the soil are crushed by the crushing roller, the surface soil is turned over by the soil turning device to expose the deep soil, and at the same time, the larger hard objects in the soil are pushed aside. The No. 1 and No. 2 nozzles on the repair liquid spraying device spray the internal soil repair liquid into the soil, and then the turned surface soil is covered again by the soil covering device.

[0009] Furthermore, a plurality of connection blocks are fixedly connected to the inner side surface of the soil covering device.

[0010] Furthermore, the front end of the front end stopper is a circular structure, which is more evenly stressed and less prone to damage.

[0011] When in use, the repair vehicle body continues to move forward, the crushing roller crushes the soil blocks on the surface of the soil, and the crushed soil blocks are accumulated on the soil-turning device, pressing the front end block toward the side limit plate. The spring damper contracts after being under pressure, and the movable connecting plate connected to the side rotation of the front end block expands to both sides during the movement of the front end block, driving the side movable plate connected to the side rotation to push the accumulated soil and hard objects to the outside of the front end block, and push the crushed surface soil to both sides, which is convenient for spraying soil repair liquid on the deep soil, and at the same time, it can also push out the hard objects in the soil to avoid drug waste.

[0012] Furthermore, a connecting hole is provided at the center of the nozzle, and the connecting hole and the motor are connected by threads.

The partition plate fixedly connected to the inner wall of the connecting partition can break up the liquid droplets during rotation, so that they become mist and are sprayed out from the No. 2 nozzle. At the same time, the liquid droplets dripping into the No. 2 connecting groove will also be sprayed out from the No. 1 nozzle on the side due to the centrifugal effect. When the soil is repaired, the soil remediation liquid is more easily absorbed by the soil, thereby accelerating the repair rate and improving the repair effect.

[0018] Beneficial effects:

[0019] 1. When the mine geological contaminated soil remediation device is in use, the remediation vehicle body is continuously pushed forward, the crushing roller crushes the soil blocks on the surface of the soil, and the soil remediation liquid inside the liquid storage device enters the liquid outlet box and flows out from the liquid outlet hole opened on the liquid outlet box. The flowing liquid droplets fall into the connecting plate and the No. 2 connecting groove. The liquid droplets dripping onto the connecting plate will drip from the No. 2 nozzle. The partition plate can break up the liquid droplets when rotating, so that it becomes mist and is sprayed out from the No. 2 nozzle. At the same time, the liquid droplets dripping onto the No. 2 connecting groove will also be sprayed out from the No. 1 nozzle on the side due to the centrifugal effect. When the soil is remediated, the soil remediation liquid is more easily absorbed by the soil, thereby accelerating the remediation rate and improving the remediation effect.

[0020] 2. When the mine geological contaminated soil remediation device is in use, the remediation vehicle body is continuously pushed forward, the crushing roller crushes the soil blocks on the surface of the soil, and the crushed soil blocks are accumulated on the soil turning device, pressing the front end block toward the side limit plate, and the spring damper contracts after being subjected to pressure.
