Description

Technical Field

[0001] This invention belongs to the field of soil remediation technology, and more specifically, relates to an in-situ soil remediation device. Background Technology

[0002] When pollutants enter the ecological cycle system, if they exceed the soil's self-purification capacity, soil pollution occurs. Soil can buffer the harm caused by pollutants to a certain extent due to its adsorption capacity, redox reactions, and microbial decomposition. However, its purification capacity is ultimately limited. Therefore, in-situ soil remediation equipment is often used to treat contaminated soil in situ, eliminating the need to transport the soil to other locations.

[0003] Existing in-situ soil remediation equipment typically applies solid and liquid remediation agents directly to the soil when treating contaminated soil. Then, a crushing process is used to thoroughly mix the remediation agents with the soil. However, there is more remediation agent in the surface layer of the soil and less in the deeper layers, resulting in uneven distribution of the remediation agent and poor treatment effect. Summary of the Invention

[0004] The purpose of this invention is to provide a soil in-situ remediation device, which aims to solve the technical problems of uneven distribution of remediation agents and poor soil treatment effect in existing soil in-situ remediation devices.

[0014] In one possible implementation, the bulk material mechanism includes a solid material conveying assembly and a liquid material conveying assembly; the solid material conveying assembly is provided with a solid discharge end corresponding to one of the plurality of shovel teeth, and the liquid material conveying assembly is provided with a liquid discharge end corresponding to one of the plurality of solid discharge ends, and the solid discharge ends and the corresponding liquid discharge ends are spaced apart along the first direction on the rear side of the shovel teeth.

[0015] Each of the solid discharge ends and the corresponding liquid discharge end forms a set of bulk material discharge ends.

[0016] In some embodiments, the solid material conveying assembly includes:

[0017] A solid material storage tank is installed on the vehicle body and located above the loosening shovel;

[0018] Multiple sets of material discharge bins correspond one-to-one with multiple sets of loosening shovels. The material discharge bins extend along the second direction and their upper ends are connected to the solid material storage tank.

[0019] Multiple feed pipes correspond one-to-one with multiple shovel teeth. The upper end of each feed pipe is connected to the liquid storage tank, and the lower end is placed behind the corresponding shovel tooth, forming the liquid outlet.

[0020] For example, the feed pipe includes:

[0021] A straight pipe, with its upper end connected to the corresponding material discharge bin and its lower end extending downwards to above the shovel teeth;

[0035] The extrusion block has a retracted state that abuts against the rear side of the limiting block, and the extrusion block also has an extended state that extends along the first direction and presses against the bulk material end.

[0044] To make the technical problems, solutions, and beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0045] It should be noted that when an element is referred to as being "set on" another element, it can be directly on or indirectly on that other element. It should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention.

[0046] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a number" means two or more, unless otherwise explicitly specified.

[0047] Please refer to the following: Figures 1 to 4 The soil in-situ remediation device provided by the present invention will now be described. The soil in-situ remediation equipment includes a vehicle body 1, a deep tillage mechanism 2, and a material distribution mechanism. The direction of travel of the vehicle body 1 is defined as the first direction, and the left and right directions of the vehicle body 1 are defined as the second direction. The deep tillage mechanism 2 is mounted on the vehicle body 1. The deep tillage mechanism 2 is provided with multiple sets of loosening shovels 24 at intervals along the first direction, and the depth of the lower end of the multiple sets of loosening shovels 24 into the soil gradually increases from the rear along the first direction. Each set of loosening shovels 24 is provided with multiple shovel teeth 241 at intervals along the second direction, and the multiple shovel teeth 241 corresponding to each set of loosening shovels 24 extend into the soil to the same depth. The material distribution mechanism is mounted on the vehicle body 1. The material distribution mechanism has multiple sets of material distribution ends that correspond one-to-one with the multiple shovel teeth 241. The material distribution ends extend downward through the bottom of the vehicle body 1 and are close to the lower end of the corresponding set of shovel teeth 241. When the vehicle body 1 travels along the first direction, the shovel teeth 241 dig trenches in the soil layer at the corresponding depth, and the material distribution ends are used to distribute the soil remediation agent into the corresponding trenches.

[0048] For ease of explanation, the appendix is ​​used in this application. Figure 1 The direction of the middle arrow A is the first direction, using the attached direction. Figure 4 The direction of the middle arrow B is the second direction.

[0049] It should be noted that the shovel teeth 241 are distributed in an array, and each shovel tooth 241 has a corresponding material handling end, that is, the material handling end is also distributed in an array.

[0050] It is important to understand that when the vehicle body 1 moves forward in the first direction, it drives multiple shovel teeth 241 to move forward, and each shovel tooth 241 draws a trench in the soil. The trench is initially quite deep. After the shovel teeth 241 have passed, some of the soil on both sides of the trench will fall back into the trench, forming a shallower trench. Therefore, when the soil remediation agent falls straight down into the trench, the soil on both sides of the trench falls down from the edge of the trench at an angle into the trench. The two actions occur simultaneously, causing the soil remediation agent and the fallen soil to overlap, thus making the soil remediation agent in each soil layer evenly distributed.

[0051] In addition, it should be noted that the vehicle body 1 used in this application has a traveling mechanism that can drive the entire device to move, and the vehicle body 1 is also provided with a receiving cavity for accommodating the solid material storage tank 31 and the liquid material storage tank 41. The specific structure of the vehicle body 1 belongs to the prior art and will not be described in detail here.

[0052] The soil in-situ remediation device provided by this invention, compared with the prior art, uses a loosening shovel 24 to loosen the soil and leave a trench of a certain depth in the soil layer, so that the distributing end of the distributing mechanism can distribute the soil remediation agent into the corresponding trench. At the same time, by making the lower end of the loosening shovel 24 extend into the soil to a depth that gradually increases backward in the first direction, the distributing end placed behind the loosening shovel 24 can distribute the soil remediation agent into the corresponding soil layer, so that the soil remediation agent is evenly distributed in soil layers at different depths, thereby improving the overall effect of soil remediation.

[0053] For ease of explanation, the foremost loosening shovel 24 is defined as the first-level loosening shovel 24, and the soil layer it cuts is called the first-level soil layer. The next first-level loosening shovel 24 and the corresponding soil layer are successively designated as the second-level loosening shovel 24 and the second-level soil layer. Since the second-level loosening shovel 24 extends deeper into the soil than the first-level loosening shovel 24, the second-level soil layer and the pesticide sprayed on the second-level soil layer will move simultaneously to both sides of the trench under the influence of the second-level loosening shovel 24, forming a layer of soil and a layer of pesticide stacked on both sides of the trench. The subsequent multiple loosening shovels 24 and soil layers form a similar stacked structure.

[0054] It should be understood that the agent referred to in this application is a soil remediation agent.

[0055] Optionally, an inclination angle is set between the subsequent shovel 24 and the preceding shovel 24 to prevent the subsequent shovel 24 from affecting the position and dosage of the agent applied after the preceding shovel 24; preferably, the inclination angle is in the range of 5° to 10°.

[0056] Please see Figure 1In some possible embodiments, the deep tillage mechanism 2 includes two sets of first drive assemblies, four sets of linkage assemblies 22, and a support shovel frame 23; the two sets of first drive assemblies are spaced apart on the vehicle body 1 along a first direction; each set of first drive assemblies is provided with a power output shaft 21 extending along a second direction; each power output shaft 21 has a set of linkage assemblies 22 at both ends; the linkage assemblies 22 rotate with the corresponding power output shaft 21; the four corner points of the support shovel frame 23 are respectively rotatably connected to the four sets of linkage assemblies 22; multiple sets of loosening shovels 24 are spaced apart on the support shovel frame 23 along the first direction; wherein, the two power output shafts 21 drive the corresponding side of the support shovel frame 23 to rotate around the end of the power output shaft 21 through the corresponding linkage assemblies 22, and cause the rear side of the support shovel frame 23 to tilt downward, so that the depth of the multiple sets of loosening shovels 24 into the soil gradually increases backward along the first direction.

[0057] Two sets of first drive components are used to drive the corresponding power output shafts 21 to rotate, thereby causing the connecting rod assembly 22 to rotate with the power output shafts 21. When the two power output shafts 21 rotate, they drive the support frame 23 to move back and forth, and cause the support frame to tilt to the rear, thereby changing the depth of the shovel teeth 241 into the soil.

[0058] Optionally, the first drive assembly is a drive motor and a gear transmission assembly. The drive motor drives the power output shaft 21 to rotate through the gear transmission assembly. Specifically, the power end of the drive motor is provided with a first gear, and the power transmission shaft 21 is provided with a second gear. The first gear and the second gear mesh and transmit power.

[0059] It should be noted that one end of the connecting rod assembly 22 is fixed to the power output shaft 21. Specifically, the connecting rod assembly 22 can be keyed to the power output shaft 21; and the lower end of the connecting rod assembly 22 is rotatably connected to the support frame 23. Specifically, the connecting rod assembly 22 includes a rotating disk and a connecting rod, one end of which is fixed to the rotating disk, and the other end is rotatably connected to the support frame 23.

[0060] Please see Figure 1 In some possible embodiments, the bulk material mechanism includes a solid material conveying assembly 3 and a liquid material conveying assembly 4; the solid material conveying assembly 3 is provided with a solid discharge end corresponding to a plurality of shovel teeth 241, and the liquid material conveying assembly 4 is provided with a liquid discharge end corresponding to a plurality of solid discharge ends, the solid discharge ends and the corresponding liquid discharge ends are spaced apart along a first direction on the rear side of the shovel teeth 241; wherein, each solid discharge end and the corresponding liquid discharge end form a set of bulk material ends.

[0061] To improve the effectiveness of soil remediation, this application employs a method of using both solid remediation agents and liquid remediation agents simultaneously, and the specific components and application methods of the solid and liquid remediation agents are all existing technologies.

[0062] Please see Figure 1 In some embodiments, the solid material conveying assembly 3 includes a solid material storage tank 31, multiple sets of material drop bins 32, and multiple conveying pipes 33; the solid material storage tank 31 is mounted on the vehicle body 1 and located above the loosening shovel 24; the multiple sets of material drop bins 32 correspond one-to-one with the multiple sets of loosening shovels 24, the material drop bins 32 extend along the second direction, and their upper ends are connected to the solid material storage tank 31; the multiple conveying pipes 33 correspond one-to-one with multiple shovel teeth 241, the upper ends of the conveying pipes 33 are connected to the lower ends of the material drop bins 32 above the corresponding shovel teeth 241, and the lower ends form solid material discharge ends.

[0063] Specifically, the solid material repair agent enters the corresponding conveying pipe 33 through the solid material storage tank 31 and the discharge bin 32, so that the solid material repair agent can be specifically delivered to the solid discharge end through the conveying pipe 33.

[0064] Optionally, the front and rear side walls of the material discharge bin 32 are inclined downwards in the vertical direction toward the center of the material discharge bin 32, so that the cross-sectional dimensions of the material discharge bin 32 gradually decrease from top to bottom, which facilitates material discharge.

[0065] Please see Figure 1 and Figure 3 For example, the conveying pipe 33 includes a straight pipe 331 and a first flexible pipe 332; the upper end of the straight pipe 331 is connected to the corresponding discharge bin 32, and the lower end extends downward to above the shovel teeth 241; the first flexible pipe 332 is placed behind the corresponding shovel teeth 241; the upper end of the first flexible pipe 332 is connected to the straight pipe 331, and the lower end forms a solid discharge end.

[0066] By setting a straight pipe 331, the solid material repair agent can fall under the action of gravity. By setting a first flexible hose 332, the solid material repair agent can fall along the contour line of the back side of the shovel tooth 241 into the back side of the corresponding shovel tooth 241, so that the solid material repair agent is accurately delivered and targeted application is achieved.

[0067] Please see Figure 1 In some embodiments, the liquid conveying assembly 4 includes a liquid storage tank 41 and multiple liquid delivery pipes 42; the liquid storage tank 41 is mounted on the vehicle body 1 and positioned behind the solid storage tank 31; the multiple liquid delivery pipes 42 correspond one-to-one with multiple shovel teeth 241, the upper end of each liquid delivery pipe 42 is connected to the liquid storage tank 41, the lower end is positioned behind the corresponding shovel teeth 241, and the lower end forms the liquid discharge end mentioned above.

[0068] The liquid repair agent is directly delivered from the liquid storage tank 41 to the liquid outlet end through the delivery pipe 42, so that the liquid repair agent falls on the rear side of the shovel teeth 241, thereby improving the accuracy of liquid repair agent application.

[0069] Please see Figure 3In some possible embodiments, each shovel tooth 241 has a limiting block 242 extending downward to near the lower end of the shovel tooth 241 on its rear side, and each limiting block 242 has a limiting channel 2421 with its axis parallel to the rear side of the corresponding shovel tooth 241; wherein, a pipeline for conveying material connected to the bulk material end passes through the limiting channel 2421, and the bulk material end extends out of the limiting channel 2421.

[0070] Specifically, the limiting block 242 is provided with two limiting channels 2421 at intervals along the first direction. The lower sections of the first hose 332 and the infusion tube 42 are respectively inserted into the two limiting channels 2421, and the lower sections of the first hose 332 and the infusion tube 42 extend out of the limiting channel 2421 to form the above-mentioned solid discharge end and liquid discharge end.

[0071] By setting the limiting block 242, the first hose 332 and the infusion tube 42 can be limited to guide the flow path of the solid repair agent and the liquid repair agent, so that the solid repair agent and the liquid repair agent fall on the rear side of the corresponding shovel tooth 241.

[0072] Please see Figure 1 or Figure 2 In some embodiments, each set of loosening shovels 24 is provided with a set of extrusion components 5, which are used to extrude the loose material end to squeeze out the soil particles gathered at the loose material end.

[0073] It should be understood that, since the solid discharge end and the liquid discharge end are close to the soil, some soil will enter the corresponding bulk material end and form clumps, which will affect the bulk material. By setting the above-mentioned extrusion component 5, the clumps formed are crushed so as to clear the protruding ends of the first hose 332 and the liquid delivery pipe 42 and ensure smooth material discharge.

[0074] Please see Figure 3 and Figure 4 For example, the extrusion assembly 5 includes a telescopic drive member 51, a connector 52, a base plate 53, multiple extrusion blocks 54, and multiple elastic members 55; the telescopic drive member 51 is mounted on the deep tillage mechanism 2; the upper end of the connector 52 is connected to the power output end of the telescopic drive member 51, and the lower end extends downward to the bottom end of the limiting block 242; the base plate 53 is located at the lower end of the connector 52; the side of the base plate 53 near the shovel teeth 241 is provided with a through hole 531 suitable for the material to pass through; the multiple extrusion blocks 54... 4 is placed on the base plate 53 and corresponds one-to-one with the shovel teeth 241; the extrusion block 54 extends along the first direction and is disposed on the rear side of the through hole 531; a plurality of elastic elements 55 correspond one-to-one with a plurality of extrusion blocks 54, one end of the elastic element 55 is connected to the rear side of the corresponding extrusion block 54, and the other end is fixed on the connector 52; wherein, the extrusion block 54 has a contracted state that abuts against the rear side of the limiting block 242, and the extrusion block 54 also has an extended state that extends along the first direction and presses against the bulk material end.

[0075] Specifically, when the first hose 332 and the infusion tube 42 are working normally, the front side of the squeezing block 54 abuts against the rear side of the limiting block 242, and the elastic element 55 is in a compressed state. When the ends of the first hose 332 and the infusion tube 42 become clumped and blocked, the telescopic drive 51 pushes the connector 52 to move downward, and the lower end of the connector 52 drives the base plate 53 to move downward. The squeezing block 54 and the elastic element 55 on the base plate 53 move accordingly. Then, after the squeezing block 54 no longer abuts against the limiting block 242, the squeezing block 54 extends forward under the push of the elastic element 55 and squeezes the bulk material end, crushing the blockage at the bulk material end so that the material can continue to be applied.

[0076] Preferably, after the device has been in operation for a period of time, the extrusion block 54 is extended forward and pressed against the bulk material end to clean the bulk material end. This cleaning operation can be performed periodically to avoid blockage.

[0077] The telescopic drive component 51 is used to drive the base plate 53 to move in a horizontal or vertical direction via the connector 52.

[0078] Optionally, the telescopic drive 51 includes a horizontally arranged first telescopic member and a vertically arranged second telescopic member. The first telescopic member is used to drive the connecting member 52 and the base plate 53 to move horizontally so that after extrusion, the extrusion block 54 moves away from the bulk material end and abuts against the limiting block 242 again. The second telescopic member is used to drive the connecting member 52 and the base plate 53 to move vertically up and down. Specifically, the first and second telescopic members can be telescopic cylinders.

[0079] It should be understood that the distance by which the first telescopic member drives the extrusion block 54 to move horizontally can be set according to actual needs, so that the extrusion block 54 abuts against the limiting block 242 again; preferably, the first telescopic member drives the extrusion block 54 to move backward away from the bulk material end along the first direction, and after the second telescopic member drives the extrusion block to move upward to the specified height, the first telescopic member drives the extrusion block 54 to move closer to the bulk material end, so that the extrusion block 54 abuts against the limiting block 242 again.

[0080] Please see Figure 1 and Figure 2 In some possible embodiments, the deep tillage mechanism 2 is also provided with a mixing mechanism 6. The mixing mechanism 6 is provided with multiple sets of mixing blades 63 at intervals along the vertical direction. The depth of the multiple sets of mixing blades 63 into the soil corresponds one-to-one with the depth of the multiple sets of loosening shovels 24 into the soil. The mixing blades 63 are used to mix the soil and soil remediation agent of the corresponding layer.

[0081] Specifically, the mixing mechanism 6 also includes a second drive assembly 61 and a mixing shaft 62, and the mixing shaft 62 is provided with multiple sets of mixing blades 63 spaced apart along its axial direction. The second drive assembly 61 drives the multiple sets of mixing blades 63 to rotate through the mixing shaft 62, so that the soil and soil remediation agent in the corresponding layer are fully mixed, improving the uniformity of the distribution of the soil remediation agent, thereby improving the effect of soil remediation.

[0082] Optionally, the second drive assembly 61 may be a drive motor used to drive the stirring shaft 62 to rotate.

[0083] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
