Description

Technical Field

[0001] This invention relates to the field of mine soil remediation technology, and in particular to a spraying device for mine soil remediation for ecological and environmental protection. Background Technology

[0002] With the continuous increase in the intensity of mineral resource development, soil pollution and ecological damage caused by mining activities are becoming increasingly prominent. A large amount of tailings and waste generated during mining, as well as harmful substances such as heavy metals and chemical agents leaked during mining and beneficiation, will enter the soil environment through infiltration and diffusion. Against this background, mine soil remediation has become one of the key tasks of ecological and environmental protection. There are many types of soil remediation technologies, including chemical remediation, bioremediation, and composite remediation. All of these technologies require the application of remediation agents, such as chelating agents, amendments, microbial agents, and nutrient solutions, to contaminated soil to achieve soil purification and functional restoration.

[0003] However, when remediating mine soil, even if remediation solution is sprayed on its surface, the soil may become compacted, preventing the solution from fully integrating into the soil. This reduces the effectiveness of the mixture in remediating the soil and results in slow ecological restoration of the mine soil. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology mentioned above, and to propose a spraying device for mine soil remediation for ecological environmental protection.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A spraying device for mine soil remediation in ecological environmental protection includes a base, a connecting frame fixedly connected to the top of the base, a first motor fixedly connected to the top of the connecting frame, a one-way threaded rod fixedly connected to the output end of the first motor, a movable plate threadedly connected to the one-way threaded rod, the movable plate slidably connected to the connecting frame, connecting plates symmetrically fixedly connected to the side of the movable plate, a second motor fixedly connected to the side of the connecting plate, a two-way threaded rod fixedly connected to the output end of the second motor, the two-way threaded rod rotatably connected to the connecting plate, and a breaking bar threadedly connected to the two-way threaded rod. The breaking bar is slidably connected to the moving plate. The bidirectional threaded rod is driven by a first bevel gear, which meshes with a second bevel gear. The second bevel gear is fixedly connected to a reciprocating mechanism for squeezing the liquid into the soil. A cross brace is fixedly connected to the side of the moving plate. A frame is fixedly connected to the end of the cross brace away from the moving plate. Multiple sets of extrusion tubes are fixedly connected to the frame. A sliding strip is slidably connected to the extrusion tube. An inlet is opened on the side of the extrusion tube and fixedly connected to a distribution plate. The distribution plate is connected to a distribution tank. The distribution tank is connected to a remedial liquid carrier tank.

[0006] The above technical solution further includes: A mounting plate is fixedly connected to the lower part of the connecting frame. A second bevel gear is rotatably connected to the mounting plate. A side plate is fixedly connected to the side of the mounting plate. The side plate is rotatably connected to the first bevel gear. The reciprocating mechanism includes a disc fixedly connected to the second bevel gear. A protrusion that slides inside an elliptical ring is eccentrically fixedly connected to the disc. A stabilizing block is fixedly connected to the lower part of the elliptical ring. The stabilizing block is fixedly connected to the mounting plate. The stabilizing block is slidably connected to the lower connecting rod. A sliding strip is fixedly connected to the end of the lower connecting rod away from the elliptical ring.

[0007] The bidirectional threaded rod is connected to a belt, and a first bevel gear is fixedly connected to the end of the belt away from the bidirectional threaded rod.

[0008] A cut is provided on the top of the base for the contact between the crushing bar and the extrusion tube and the soil.

[0009] A fixing mechanism for fixing the repair fluid carrier box is provided above the base. The fixing mechanism includes a support set above the base, a fixing frame fixedly connected to the side of the support, a pull rod slidably connected to the fixing frame, a sliding plate fixedly connected to the surface of the pull rod, the sliding plate being slidably connected to the fixing frame, an extension rod for inserting into a hole on the side of the repair fluid carrier box at one end of the pull rod, a spring fixedly connected to one end of the sliding plate, and a fixing frame fixedly connected to the end of the spring away from the sliding plate. Two sets of fixing mechanisms are symmetrically arranged on both sides of the repair fluid carrier box.

[0010] The repair fluid carrier tank is securely fixed and easy to install and remove, improving equipment operation and maintenance efficiency. A symmetrical fixing mechanism consisting of supports, fixing frames, tie rods, sliding plates, and springs utilizes the elastic potential energy of the springs to drive the extension rod of the tie rod into the hole of the repair fluid carrier tank, achieving rapid and stable fixing of the carrier tank. Disassembly only requires pulling the tie rod to release the fixation, eliminating the need for complex tools. This significantly reduces the difficulty and time required for carrier tank replacement and maintenance, ensuring continuous equipment operation.

[0011] A mounting base is fixedly connected above the base, and the mounting base is used to raise the height of the repair fluid carrier tank.

[0012] The frame is fixedly connected to the liquid separator.

[0013] The mounting base raises the height of the repair fluid carrier tank, which can make full use of the principle of communicating vessels to form a natural pressure difference. Combined with the fixed connection between the distribution tank and the frame, it ensures the stability of the distribution tank position, so that the repair fluid can flow smoothly and evenly to each extrusion tube, avoiding problems such as interruption of fluid supply and uneven distribution caused by insufficient height of the carrier tank or shaking of the distribution structure.

[0014] A pressure valve is provided at the bottom of the extrusion tube, and the pressure valve is used to push the liquid out of the extrusion tube by the sliding bar.

[0015] The pressure valve at the bottom of the extrusion tube can strictly control the timing of the remediation fluid outflow. It opens the fluid outlet only when the sliding bar pushes to form sufficient pressure, effectively preventing premature leakage of the remediation fluid in the unextruded state and ensuring that all the remediation fluid is delivered into the deep soil under pressure, further improving the utilization rate of the remediation fluid.

[0016] The base is equipped with multiple sets of casters for movement.

[0017] The multiple sets of rollers at the bottom of the base allow the equipment to move flexibly, making it easy for staff to adjust the working position according to the repair needs. It is especially suitable for complex and irregular terrains such as mine slopes and gullies, solving the problems of poor mobility and difficulty in full coverage of traditional equipment, and improving the efficiency and coverage of mine soil remediation.

[0018] The present invention has the following beneficial effects: 1. This invention achieves precise and efficient delivery of the remediation fluid, reducing remediation costs. The equipment forms a sealed cavity through the cooperation of a sliding strip and an extrusion tube, actively extruding the remediation fluid into the deep soil. A pressure valve design prevents premature leakage of the remediation fluid. Simultaneously, leveraging the height advantage of the remediation fluid carrying tank and the diversion effect of the distribution tank and distribution plate, it ensures that the remediation fluid enters each extrusion tube evenly. This improves the contact efficiency between the remediation fluid and deep contaminants, reduces waste, and lowers the overall cost of mine soil remediation.

[0019] 2. In this invention, the integration of the remediation fluid with the soil is effectively improved, solving the problem of low remediation efficiency of compacted soil. The second motor drives the bidirectional threaded rod to rotate, causing the breaking strip to slide back and forth as it penetrates the soil. This directly breaks up the compacted layer on the soil surface, breaking down the obstruction of the compacted soil to the penetration of the remediation fluid. This allows the remediation fluid delivered by the subsequent extrusion pipe to more smoothly integrate into the deeper soil layers, avoiding the remediation fluid remaining on the surface and failing to play its role. This significantly improves the soil remediation effect and accelerates the process of ecological environment restoration in mine soil. Attached Figure Description

[0025] In one embodiment, the bidirectional threaded rod 15 is driven by a belt 19, and a first bevel gear 22 is fixedly connected to one end of the belt 19 away from the bidirectional threaded rod 15.

[0026] In one embodiment, for the base 1 described above, a cutout 6 is provided on the top of the base 1, and the cutout 6 is used for the contact between the crushing bar 17 and the extrusion tube 33 and the soil.

[0027] In one embodiment, for the base 1, a fixing mechanism for fixing the repair fluid carrier 13 is provided on the top of the base 1. The fixing mechanism includes a support 7 provided on the top of the base 1, a fixing frame 8 fixedly connected to the side of the support 7, a pull rod 9 slidably connected to the fixing frame 8, a sliding plate 10 fixedly connected to the surface of the pull rod 9, the sliding plate 10 slidably connected to the fixing frame 8, an extension rod for inserting into the side hole of the repair fluid carrier 13 is provided at one end of the pull rod 9, a spring 11 is fixedly connected to one end of the sliding plate 10, and the fixing frame 8 is fixedly connected to the end of the spring 11 away from the sliding plate 10. Two sets of fixing mechanisms are symmetrically arranged on both sides of the repair fluid carrier 13.

[0028] In this embodiment, the repair fluid carrier box is securely fixed and easy to assemble and disassemble, improving equipment operation and maintenance efficiency. A symmetrical fixing mechanism consisting of a support 7, a fixing frame 8, a pull rod 9, a sliding plate 10, and a spring 11 is used. The elastic potential energy of the spring 11 drives the extension rod of the pull rod 9 to insert into the hole of the repair fluid carrier box 13, achieving rapid and stable fixing of the carrier box. Disassembly only requires pulling the pull rod 9 to release the fixation, eliminating the need for complex tools and significantly reducing the difficulty and time required for carrier box replacement and maintenance, ensuring continuous equipment operation.

[0029] In one embodiment, for the base 1, a mounting base 12 is fixedly connected above the base 1, and the mounting base 12 is used to raise the height of the repair fluid carrier tank 13.

[0030] In one embodiment, the frame 29 is fixedly connected to the liquid distribution tank 32.

[0031] In this embodiment, the mounting base 12 raises the height of the repair fluid carrier tank 13, which can make full use of the principle of communicating vessels to form a natural pressure difference. Combined with the fixed connection between the dispensing tank 32 and the frame 29, it ensures that the position of the dispensing tank 32 is stable, so that the repair fluid can flow smoothly and evenly to each extrusion tube 33, avoiding problems such as interruption of fluid supply and uneven distribution caused by insufficient height of the carrier tank or shaking of the dispensing structure.

[0032] In one embodiment, for the extrusion tube 33, a pressure valve is provided at the bottom of the extrusion tube 33, and the pressure valve is used for the sliding bar 28 to push the extrusion tube 33 to extrude liquid.

[0033] In this embodiment, the pressure valve at the bottom of the extrusion tube 33 can strictly control the timing of the remediation fluid outflow. The fluid is only released when the sliding bar 28 pushes to form sufficient pressure, which effectively avoids premature leakage of the remediation fluid in the unextruded state and ensures that all the remediation fluid is delivered into the deep soil under pressure, further improving the utilization rate of the remediation fluid.

[0034] In one embodiment, the base 1 described above has multiple sets of rollers at its bottom for movement.

[0035] In this embodiment, the design of multiple sets of rollers at the bottom of the base 1 allows the equipment to move flexibly, making it easy for staff to adjust the working position according to the repair needs. It is especially suitable for complex and irregular terrains such as mine slopes and gullies, solving the problems of poor mobility and difficulty in full coverage of traditional equipment, and improving the work efficiency and coverage of mine soil remediation.

[0036] The working principle of the spraying device for mine soil remediation in this invention is as follows: First, the operator moves the device to the mine area where the soil needs to be remediated. Then, the remediation liquid carrier tank 13 is mixed with the liquid to be sprayed. Then, the control panel on the side of the connecting frame 2 is controlled to rotate the output end of the first motor 3. The rotation of the output end of the first motor 3 will drive the one-way threaded rod 4 to rotate. The rotation of the one-way threaded rod 4 will cause the moving plate 5 to slide along the side of the connecting frame 2. Then, the moving plate 5 will drive the breaking strip 17 to penetrate the soil to a certain depth, and the moving plate 5 will drive the extrusion tube 33 to penetrate the soil to a certain depth through the cross support frame 18.

[0037] After adjusting the parameters, the staff controlled the movement of base 1 via remote control. During the soil repair process, the output of the second motor 16 was rotated, which in turn drove the bidirectional threaded rod 15 to rotate. The rotation of the bidirectional threaded rod 15 caused the breaking strip 17 to slide back and forth on its surface. As the breaking strip 17 penetrated deeper into the soil, it slid left and right to break up the hardened soil surface. At the same time, the rotation of the bidirectional threaded rod 15 drove the first bevel gear 22 to rotate via belt 19. The first bevel gear 22 then meshed with the second bevel gear 23. The rotation of the second bevel gear 23 then drove the disc 201 to rotate. The disc 201 then caused the protrusion 24 to perform eccentric circular motion inside the elliptical ring 25, thus realizing the up-and-down reciprocating motion of the elliptical ring 25. The elliptical ring 25 then drove the sliding rod 26 at its bottom to slide. The sliding bar 28 moves up and down reciprocatingly. When the bottom end of the sliding bar 28 rises to the upper opening of the extrusion tube 33, the mixed liquid inside the repair fluid carrier tank 13 first enters the interior of the distribution tank 32. Then, the liquid in the distribution tank 32 flows evenly along the distribution plate 31 into the interior of the extrusion tube 33. When the sliding bar 28 extrudes downward, it slides down through the opening of the distribution plate 31 and forms a sealed cavity with the extrusion tube 33. At this time, the mixed liquid inside the extrusion tube 33 is forced into the soil. A pressure valve is provided at the bottom of the extrusion tube 33. Before the sliding bar 28 extrudes, the mixed liquid will not flow out from the bottom of the extrusion tube 33. Then, the mixed liquid is squeezed into the soil from the bottom of the extrusion tube 33, thereby sending the mixed liquid into the deep soil, improving the contact efficiency with pollutants, and flowing into the soil that is more suitable for loose and porous soil. For compacted soil, uneven penetration and surface retention problems are likely to occur.

[0038] In addition, a mounting base 12 is provided above the base 1 to increase the height of the repair fluid carrier tank 13 so that the mixture can smoothly enter the interior of the extrusion tube 33 using the principle of communicating vessels. Furthermore, fixing mechanisms for fixing the repair fluid carrier tank 13 are provided on both sides of the repair fluid carrier tank 13. When the service life of the repair fluid carrier tank 13 reaches its limit, the pull rod 9 is pulled, and then the pull rod 9 drives the sliding plate 10 to overcome the elastic force of the spring 11. Then the extension rod on one side of the pull rod 9 disengages from the repair fluid carrier tank 13. When it is necessary to install the repair fluid carrier tank 13, the pull rod 9 is pulled, and then the repair fluid carrier tank 13 is placed between the two fixing mechanisms. Then the pulling force on the pull rod 9 is released, and then the spring 11 releases its elastic potential energy. Then the sliding plate 10 drives the extension rod on the side of the pull rod 9 to insert into the hole on the side of the repair fluid carrier tank 13, thereby achieving fixation.

[0039] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
