Description

TECHNICAL FIELD

[0001] The application relates to the technical field of soil remediation, in particular to a mine geological contaminated soil remediation device. BACKGROUND

[0002] Soil remediation refers to the use of physical, chemical and biological methods to transfer, absorb, degrade and transform pollutants in soil, so that the concentration of the pollutants is reduced to an acceptable level, or the toxic and harmful pollutants are converted into harmless substances, so that the purpose of soil remediation is achieved. Physical methods include heat treatment, engineering measures, electric remediation, filling and soil covering, etc. Chemical methods are used to adjust the mobility of heavy metals in soil through chemical reactions to remediate contaminated soil. Chemical reagents are used to adjust or reduce the concentration, solubility and free state of heavy metals, increase the content of soil organic matter, and change the soil electrolytic property. Biological methods use naturally growing or genetically engineered plants to reduce the content of heavy metals in soil, simultaneously improve the soil nutrient conditions and restore the function of the soil, and optimize the microenvironment.

[0003] The device for remediation of mine geological contaminated soil disclosed in the publication CN115647018A belongs to the technical field of soil remediation and comprises a vehicle body and a storage tank. A storage tank is arranged on the left side wall at the top of the vehicle body. An installation frame is arranged on the right side wall at the top of the vehicle body. An installation plate is slidably arranged in the inner cavity of the installation frame. An electric push rod is arranged on the top wall of the installation frame. The electric push rod extends into the inner cavity of the installation frame and is connected to the top wall of the installation plate. Holes are uniformly arranged on the installation plate. A liquid injection pipe is inserted into the holes. The inner cavity of the liquid injection pipe is connected to the inner cavity of the storage tank through a conduit. A protective sleeve is arranged on the bottom of the outer wall of the liquid injection pipe. Liquid outlets are uniformly arranged on the bottom of the outer wall of the liquid injection pipe. The liquid outlets are arranged in the inner cavity of the protective sleeve. The liquid injection pipe is not in direct contact with the soil, so that the soil is prevented from entering the liquid outlets of the liquid injection pipe and the liquid outlets of the liquid injection pipe are prevented from being blocked, thereby ensuring that the remediation liquid is normally injected into the soil and the quality of soil remediation is ensured.

[0004] The existing device for remediation of mine geological contaminated soil injects soil remediation liquid into the soil through a liquid injection pipe. However, the liquid injection hole arranged on the liquid injection pipe is easily blocked by soil during the injection process, thereby affecting the injection speed. In this way, the state of the soil needs to be considered. In places where the soil density is relatively high, the soil remediation liquid is easily accumulated near the hole after injection, is not easy to spread, thereby affecting the soil remediation effect and easily causing waste. SUMMARY

[0005] In order to overcome the above-mentioned defects of the prior art, the application provides a device for remediation of mine geological contaminated soil to solve the problems in the background art.

[0006] This invention provides the following technical solution: a soil remediation device for mine geological pollution, comprising a remediation vehicle body, two secondary hydraulic devices fixedly connected to the bottom of the remediation vehicle body, one secondary hydraulic device fixedly connected to the center of the bottom of the remediation vehicle body, with a remediation liquid spraying device fixedly connected to its bottom, and the other secondary hydraulic device located at the rear of the remediation vehicle body, with a soil covering device fixedly connected to its bottom, the remediation liquid spraying device comprising a device shell, a liquid outlet tank fixedly connected inside the device shell, a liquid storage device fixedly connected to the top of the device shell, the liquid storage device being fixedly connected to the secondary hydraulic device, a plurality of liquid outlet holes being opened at the bottom of the liquid outlet tank, a motor being rotatably connected to the center of the liquid outlet tank, a nozzle being fixedly connected to the bottom of the motor, the nozzle having a first nozzle and a second nozzle, a primary hydraulic device being fixedly connected to the side of the remediation vehicle body, a crushing roller being rotatably connected to the bottom of the primary hydraulic device, and a soil turning device being fixedly connected to the bottom of the front side of the remediation vehicle body;

[0007] The soil turning device includes a front stop block, a spring damper fixedly connected to the bottom of the front stop block, a side limiting plate fixedly connected to the bottom of the spring damper, a movable connecting plate rotatably connected to the side of the front stop block, a side movable plate rotatably connected to the side of the movable connecting plate, a movable groove provided on the side limiting plate, the side movable plate and the movable groove being connected in cooperation, and the side movable plate and the side limiting plate being movably connected.

[0008] During use, the crushing roller crushes the soil clods, the soil turning device turns over the surface soil to expose the deeper soil, and pushes the larger hard objects in the soil aside. The No. 1 and No. 2 nozzles on the repair liquid spraying device spray the soil repair liquid into the soil, and then the soil covering device covers the turned-over surface soil again.

[0009] Furthermore, multiple connecting blocks are fixedly connected to the inner side of the soil covering device.

[0010] Furthermore, the front end of the front stop has a circular structure, which makes the force more even and less prone to damage.

[0011] During use, the repair vehicle continuously moves forward, and the crushing rollers crush the soil clods on the surface. The crushed soil clods accumulate on the soil turning device, pressing the front stop towards the side limiting plate. The spring damper contracts under pressure, and the movable connecting plate on the side of the front stop rotates and unfolds to both sides during the movement of the front stop. This drives the movable side plate, which rotates and connects to the side, to push the accumulated soil and hard objects to the outside of the front stop, pushing the crushed surface soil to both sides. This facilitates the spraying of soil remediation liquid on the deeper soil and also pushes hard objects in the soil outward, avoiding waste of the medicine.

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

[0013] Furthermore, the nozzle has a third connecting groove at its bottom, a connecting plate is fixedly connected to the inner wall of the third connecting groove, a second nozzle is provided on the connecting plate, and a partition plate is fixedly connected to the inner wall of the third connecting groove.

[0014] Furthermore, a first connecting groove is formed on the side of the nozzle, and a first nozzle is formed on the first connecting groove.

[0015] Furthermore, a connecting partition is fixedly connected to the nozzle, the connecting partition is disposed on both sides of the third connecting slot, a guide plate is fixedly connected to the other side of the connecting partition, the bottom of the guide plate is provided with a second connecting slot, and the first nozzle is disposed on the side of the second connecting slot.

[0016] Furthermore, the upper surface of the guide plate is inclined, and the lowest end is biased towards the position of the second connecting groove.

[0017] During use, the soil remediation solution inside the storage device enters the outlet tank and flows out from the outlet hole on the outlet tank. The flowing droplets fall onto the nozzle, some of which flow into the connecting plate between the connecting baffles, while the rest slides off the guide plate into the second connecting groove. The droplets that fall onto the connecting plate will drip down from the second nozzle. During spraying, the motor drives the nozzle to rotate. The baffles fixedly connected to the inner wall of the connecting baffles can disperse the droplets into a mist and spray it out from the second nozzle. At the same time, the droplets that fall into the second connecting groove will also be sprayed out from the first nozzle on the side due to centrifugal force. During soil remediation, the soil remediation solution is more easily absorbed by the soil, thereby accelerating the remediation rate and improving the remediation effect.

[0018] Beneficial effects:

[0019] 1. In operation, the soil remediation device for mine geological pollution works as follows: the remediation vehicle continuously moves forward, and the crushing rollers crush the soil clods on the surface. The soil remediation liquid inside the storage device enters the outlet tank and flows out from the outlet hole on the outlet tank. The outflowing droplets fall into the connecting plate and the second connecting groove. The droplets falling onto the connecting plate drip down from the second nozzle. The partition plate can disperse the droplets into a mist when rotating, spraying them out from the second nozzle. At the same time, the droplets falling into the second connecting groove are also sprayed out from the first nozzle on the side due to centrifugal force. During soil remediation, the soil remediation liquid is more easily absorbed by the soil, thereby accelerating the remediation rate and improving the remediation effect.

[0020] 2. In use, the soil remediation device for mine geological pollution involves the remediation vehicle continuously moving forward. The crushing rollers crush the surface soil clods, which accumulate on the turning device. The front stop is pressed towards the side limiting plate, and the spring damper contracts under pressure. The movable connecting plate on the side of the front stop expands to both sides during the movement of the front stop, driving the movable side plate to push the accumulated soil and hard objects to the outside of the front stop. This pushes the crushed surface soil to both sides, facilitating the spraying of soil remediation liquid on deeper soil layers. It also pushes hard objects out of the soil, avoiding waste of the remediation agent. Attached Figure Description
