Description

Technical Field

[0001] The invention relates to the technical field of mining engineering, in particular to a soil remediation device for mining engineering. Background Art

[0002] Mining engineering and soil remediation are closely related. Mining engineering often involves mining, transportation and processing of ores, which may cause damage to the soil and the environment. Soil remediation is committed to restoring contaminated or damaged soil to reduce environmental impacts and ensure that the land can be used again or maintain ecological balance.

[0003] Currently, in the process of soil remediation, spraying remediation liquid on the contaminated soil is a common remediation method. However, this remediation method has obvious defects. The remediation liquid has better remediation ability for the soil sprayed on the surface, while the remediation liquid tends to penetrate and lose quickly on the surface of the soil and may not be able to effectively penetrate into the deep soil, resulting in extremely limited remediation ability. Summary of the invention

[0005] To achieve the above objectives, the present invention provides a soil remediation device for mining engineering, comprising a device frame, a feed barrel is fixedly mounted on the device frame, an input end of the feed barrel is fixedly connected to a crushing box, a crushing mechanism is provided on the crushing box, the inner surface of the feed barrel is rotatably connected to a rotating shaft, an outer surface of the rotating shaft is provided with a feed spiral sheet, a driving mechanism for driving the rotating shaft to rotate is provided on the device frame, a plurality of groups of liquid adding pipes are provided on the feed barrel, an output end of the feed barrel is fixedly connected to a feed discharge pipe, a mixing drum is provided on the device frame, the interior of the mixing drum is rotatably connected to a mixing shaft through a linkage mechanism, a stirring and turning mechanism is provided on the outer surface of the mixing shaft, and a manual discharging mechanism is provided at the bottom end of the mixing drum.

[0006] Preferably, the crushing mechanism includes a motor fixedly mounted on the outer surface of the crushing box, and the output end of the motor is fixedly connected to a crushing roller. Large pieces of soil can be crushed by the crushing mechanism to prevent them from being difficult to transport normally in the feed tube, and also to allow the repair liquid to penetrate into the soil more thoroughly.

[0007] Preferably, the driving mechanism includes a motor fixedly mounted on a device frame, and the output end of the motor is fixedly connected to a driving wheel. The driving mechanism can drive the rotating shaft, thereby cooperating with the feeding spiral to feed the crushed soil. During the feeding process, repair liquid can be added to the feeding barrel through a liquid adding pipe relatively evenly distributed on the surface of the feeding barrel.

[0008] Preferably, the outer surface of the driving wheel is slidably connected to a conveyor belt, the inner end of the conveyor belt away from the driving wheel is slidably connected to a transmission wheel, and the axis of the transmission wheel is fixedly connected to one end of the rotating shaft.

[0009] Preferably, the linkage mechanism includes an upper gear fixedly connected to the top of the stirring shaft, and a side gear is fixedly connected to the end of the rotating shaft away from the transmission wheel. The outer surface of the side gear is meshed with the outer surface of the upper gear. Through the linkage mechanism, the soil in the mixing drum can be stirred by cooperating with the stirring and turning mechanism during the process of conveying the soil.

[0010] Preferably, the stirring and turning mechanism includes a fixed frame fixedly mounted on the outer surface of the stirring shaft, a plurality of stirring plates are arranged at the bottom of the fixed frame, filter holes are opened on the outer surface of the stirring plates, and a scraper is arranged on the outer surface of the stirring plates. The stirring and turning mechanism can stir the soil in the mixing drum more thoroughly so that the repair liquid can be fully integrated into the soil.

[0011] Preferably, the outer surface of the stirring shaft is provided with a material guiding spiral sheet, and the interior of the stirring barrel is fixedly connected with a material guiding pipe rack.

[0012] Preferably, the manual discharging mechanism includes a discharging valve fixedly connected to the bottom of the mixing drum, the inner surface of the discharging valve is rotatably connected to a damping shaft, the damping shaft has a damping characteristic, and can remain relatively stable after rotating to a corresponding position, and an appropriate amount of soil that has been fully dissolved with the repair liquid can be discharged at an appropriate time through the manual discharging mechanism.

[0013] Preferably, a material blocking plate is fixedly sleeved on the outer surface of the damping shaft, and a rotary handle is provided at one end of the damping shaft.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The soil remediation device for mining projects can significantly increase the specific surface area of ​​the soil by crushing the contaminated soil into smaller particles. The repair liquid is continuously injected into the feeding tube through the liquid filling tube, so that the repair liquid can keep in contact with the soil for a long time, and the repair liquid can penetrate into the soil faster, so that the crushed soil and the repair liquid are mixed more evenly in the feeding tube. Compared with the traditional method of spraying the repair liquid only on the surface, it can avoid the problem of shallow penetration of the repair liquid and ensure that the repair liquid can reach deeper soil.

[0015] 2. The soil remediation device for mining projects stirs the soil through the stirring and turning mechanism. The design of the stirring shaft and the stirring plate in the mixing drum enables the soil to be evenly mixed during the mixing process, avoiding the problem of uneven mixing. The design of the material guide spiral blade and the material guide pipe rack ensures the uniform distribution of the soil in the mixing drum, preventing stratification during the mixing process, thereby improving the uniformity of mixing.

[0016] 3. The soil remediation device for mining projects has filter holes on the stirring plate that can accelerate the passage of soil and reduce the difficulty of mixing. The scraper at the edge can remove the soil attached to the inner wall of the mixing drum, keeping the inside of the mixing drum clean and avoiding affecting subsequent processing. The subsequent adjustment of the inclination angle of the blocking plate can control the discharge rate according to different environmental conditions and soil types. This flexible design can avoid uneven mixing and loss of repair liquid due to too fast discharge. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] See also Figure 1-6 A soil remediation device for mining engineering comprises a device frame 1, on which a feed barrel 2 is fixedly mounted, an input end of the feed barrel 2 is fixedly connected to a crushing box 3, a crushing mechanism is arranged on the crushing box 3, an inner surface of the feed barrel 2 is rotatably connected to a rotating shaft 6, an outer surface of the rotating shaft 6 is provided with a feed spiral sheet 7, a driving mechanism for driving the rotating shaft 6 to rotate is arranged on the device frame 1, a plurality of groups of liquid adding pipes 12 are arranged on the feed barrel 2, an output end of the feed barrel 2 is fixedly connected to a feed discharge pipe 13, a stirring drum 14 is arranged on the device frame 1, the interior of the stirring drum 14 is rotatably connected to a stirring shaft 15 through a linkage mechanism, a stirring and turning mechanism is arranged on the outer surface of the stirring shaft 15, and a manual discharging mechanism is arranged at the bottom end of the stirring drum 14.

[0021] Through the above technical scheme, during the use of the soil remediation device, the contaminated soil can be first excavated, and then the soil can be put into the crushing box 3. The larger volume of soil can be crushed by the crushing mechanism, and the crushed soil can be transported in the feeding barrel 2 under the action of the driving mechanism. At the same time, the repair liquid is added to each liquid adding pipe 12, and the repair liquid is immersed in the soil. Then, the soil is input into the mixing drum 14 through the feeding pipe 13. Finally, the linkage mechanism cooperates with the stirring and turning mechanism to fully stir the soil in the mixing drum 14, so that the repair liquid is fully integrated into the soil, so as to effectively and relatively thoroughly repair the soil.

[0022] Specifically, the crushing mechanism includes a motor 4 fixedly mounted on the outer surface of the crushing box 3 , and a crushing roller 5 is fixedly connected to the output end of the motor 4 .

[0023] Through the above technical solution, two groups of motors 4 and crushing rollers 5 are provided. The two groups of crushing rollers 5 can crush the soil during the offset rotation process, and crush the larger volume of soil into smaller volume of soil.

[0024] Specifically, the driving mechanism includes a motor 8 fixedly mounted on the device frame 1 , and an output end of the motor 8 is fixedly connected to a driving wheel 9 .

[0025] Through the above technical solution, when the motor 8 drives the driving wheel 9 to rotate, under the transmission action of the conveyor belt 10, it will drive the driving wheel 11 to rotate synchronously, and finally the rotating shaft 6 is linked to rotate, and the edge of the feeding spiral piece 7 is completely in contact with the inner wall of the feeding barrel 2. Therefore, the rotating shaft 6 drives the feeding spiral piece 7 to stably transport the crushed soil during the rotation process (that is, transport the soil dropped from the crushing box 3 to the discharge pipe 13).

[0026] Specifically, the outer surface of the driving wheel 9 is slidably connected to the conveyor belt 10, and the inner end of the conveyor belt 10 away from the driving wheel 9 is slidably connected to the transmission wheel 11, and the axis of the transmission wheel 11 is fixedly connected to one end of the rotating shaft 6.

[0027] Through the above technical solution, in the transmission system composed of the driving wheel 9, the conveyor belt 10 and the transmission wheel 11, the transmission angle is greater than 120 degrees. The design here is to allow the driving wheel 9 to pull the transmission wheel 11 to rotate synchronously with it through the conveyor belt 10 during the rotation.

[0028] Specifically, the linkage mechanism includes an upper gear 16 fixedly connected to the top of the stirring shaft 15 , and one end of the rotating shaft 6 away from the transmission wheel 11 is fixedly connected to a side gear 17 , and the outer surface of the side gear 17 is meshedly connected with the outer surface of the upper gear 16 .

[0029] Through the above technical solution, the rotating shaft 6 will drive the side gear 17 to rotate during the rotation process, and then the upper gear 16 meshing therewith will be linked to rotate, and finally the stirring shaft 15 will rotate. The stirring shaft 15 will trigger the stirring and turning mechanism during the rotation process.

[0030] Specifically, the stirring and turning mechanism includes a fixing frame 18 fixedly sleeved on the outer surface of the stirring shaft 15, a plurality of stirring plates 19 are arranged at the bottom of the fixing frame 18, filter holes 20 are opened on the outer surface of the stirring plates 19, and scrapers 21 are arranged on the outer surface of the stirring plates 19.

[0031] Through the above technical solution, the stirring plates 19 are evenly distributed at the bottom of the fixing frame 18, the filter holes 20 are designed to reduce the resistance when stirring the soil, allowing the soil to be stirred more easily, and the edge of the scraper 21 is in contact with the inner wall of the mixing drum 14.

[0032] Specifically, a material guiding spiral sheet 22 is disposed on the outer surface of the stirring shaft 15 , and a material guiding pipe frame 23 is fixedly connected to the interior of the stirring drum 14 .

[0033] Through the above technical solution, the edge of the material guide spiral blade 22 is in contact with the inner wall of the material guide tube frame 23. This design is to guide the soil relatively lower in the mixing drum 14 to the upper part, thereby increasing the mixing degree between the soil and the repair liquid.

[0034] Specifically, the manual discharge mechanism includes a discharge valve 24 fixedly connected to the bottom of the mixing drum 14 , and a damping shaft 25 is rotatably connected to the inner surface of the discharge valve 24 .

[0035] Through the above technical solution, the stirred soil can fall into the discharge valve 24, and the damping shaft 25 can be driven to rotate synchronously during the rotation of the handle 27. After the damping shaft 25 rotates to the corresponding angle, if no force is applied, it can remain relatively stable, thereby changing the inclination angle of the blocking plate 26.

[0036] Specifically, a material blocking plate 26 is fixedly sleeved on the outer surface of the damping shaft 25 , and a rotary handle 27 is provided at one end of the damping shaft 25 .

[0037] Through the above technical solution, when the angle of the blocking plate 26 in the discharge valve 24 changes synchronously with the damping shaft 25, the distance between it and the inner wall of the discharge valve 24 will also change accordingly. When the inclination angle is larger, the distance is larger, and the soil discharge rate is also greater.

[0038] Working principle: In the process of soil repair, the soil remediation device needs to dig out the contaminated soil first, and then put the contaminated soil into the crushing box 3, turn on the motor 4 to drive the corresponding crushing roller 5 to rotate, and the two sets of crushing rollers 5 can crush the soil during the offset rotation process, and crush the larger volume of soil into smaller volume of soil, so that the soil can be normally transported in the feeding tube 2 later, and at the same time, it is also to allow the repair liquid to be integrated into the soil faster and more thoroughly. By digging out the contaminated soil and crushing it, the specific surface area of ​​the soil can be effectively increased. This treatment method can make the distribution of the repair liquid in the soil more uniform and promote its penetration into deeper soil. Compared with the traditional method of spraying the repair liquid only on the surface, It not only solves the problem of shallow penetration of the repair liquid, but also ensures more comprehensive degradation of pollutants. The crushed soil will fall into the feed barrel 2. At this time, the motor 8 can be turned on to drive the drive wheel 9 to rotate. Under the transmission action of the conveyor belt 10, the transmission wheel 11 is pulled and rotates accordingly. During this period, the rotating shaft 6 will rotate synchronously with the rotation of the transmission wheel 11, thereby cooperating with the rotation of the feed spiral piece 7 to transport the soil. In the process of transporting the soil in the feed barrel 2, the repair liquid is injected into the feed barrel 2 through each liquid adding pipe 12. The repair liquid will continuously contact and dissolve into the soil at different positions. The method of continuously injecting the repair liquid through the liquid adding pipe 12 can keep the soil in the feed barrel 2 in contact with the repair liquid for a long time. This design ensures that the repair liquid is transported in the conveying loop. The nodes continuously react with the soil, thereby improving the remediation efficiency and ensuring that the pollutants are fully dissolved by the remediation liquid. After the soil containing the remediation liquid is transported to the discharge pipe 13 in the feed barrel 2, it can be put into the mixing drum 14 along the discharge pipe 13. At the same time, during the rotation of the rotating shaft 6, the side gear 17 at the end of the rotating shaft 6 will be driven to rotate synchronously, and the upper gear 16 meshing with it will be linked to rotate, thereby linking the stirring shaft 15 to rotate. During the rotation of the stirring shaft 15, the fixed frame 18 will drive each stirring plate 19 to stir and mix the soil in the mixing drum 14, so that the soil and the remediation liquid are dissolved more thoroughly. At the same time, when the stirring shaft 15 rotates, it will drive the guide spiral piece 22 to rotate, and cooperate with the guide pipe frame 23 to The soil at a relatively low position in the mixing drum 14 is transported to a relatively high position, and the soil is transported upward to avoid stratification during the mixing process, which proves that the system has significant advantages in enhancing the uniformity of mixing, thereby ensuring that the repair liquid can fully penetrate into each part of the soil, further improving the mixing degree of the mixing, and the repair liquid completely penetrates into the inner layer of the soil during the mixing process. The filter holes 20 on the stirring plate 19 can accelerate the passage of the soil during mixing to reduce the difficulty of mixing and improve the mixing efficiency. The scraper 21 at the edge of the stirring plate 19 can scrape the soil attached to the inner wall of the mixing drum 14 to reduce the soil residue in the mixing drum 14, ensure that the inside of the mixing drum 14 maintains a relatively clean environment, and avoid affecting the treatment of subsequent batches of soil.After the mixing is completed, the handle 27 can be rotated to drive the damping shaft 25 to rotate to adjust the inclination angle of the material blocking plate 26. According to the discharge requirements, the material blocking plate 26 is rotated to different angles to control the discharge rate, which means that under different environmental conditions and soil types, the device can respond flexibly, avoiding uneven soil mixing and loss of repair liquid caused by too fast discharge, and finally returning the discharged soil to its original position to achieve the effect of thorough and effective soil repair. In summary, the design of the soil remediation device integrates multiple advanced functions and technologies, providing an efficient, uniform and comprehensive soil remediation solution. Its main advantages include: 1. Significantly improve the remediation efficiency: The crushing and mixing process significantly increases the contact area between the soil and the repair liquid, and promotes the thorough removal of pollutants. 2. Uniform distribution and mixing: Through the stable conveying and liquid addition and stirring mechanism, the uniform distribution of the repair liquid in the soil is guaranteed, and the quality of mixing is improved. 3. Flexibility and control: The flexible adjustment capability of the discharge control system enables the equipment to adapt to different processing requirements and environmental conditions. Therefore, through a series of improvements, the soil remediation device for mining engineering has significantly improved the efficiency and effect of soil remediation. By strengthening the penetration of the remediation fluid, improving the mixing uniformity, reducing the difficulty of operation and environmentally friendly design, it has brought a more efficient and sustainable development plan to the soil remediation industry.
