Description

Technical Field

[0001] The invention relates to the technical field of soil remediation equipment, and in particular to a vehicle-mounted integrated soil leaching and remediation device. Background Art

[0002] Soil leaching is a remediation method that mixes a liquid that has the ability to dissolve pollutants with the soil, thereby transferring the pollutants to the liquid phase and a small part of the soil. The implementation methods of soil leaching remediation are mainly divided into in-situ leaching and ex-situ leaching, among which ex-situ leaching can be divided into on-site remediation and off-site remediation. The mobile soil leaching vehicle is an innovative mobile soil leaching remediation equipment that can achieve rapid remediation of contaminated soil. It has the advantages of a wide range of applications, small footprint, quick and convenient installation, and fast and flexible transfer.

[0003] For the leaching treatment of clay-like contaminated soil, the clay is usually transported to the hopper through a conveying mechanism. The hopper is equipped with a leaching liquid spraying device. The clay will be mixed with the leaching liquid when entering the drum of the scrubbing mechanism. The drum of the scrubbing mechanism can disperse, stir and wash the clay by rotating, so that the clay is fully in contact with the leaching liquid in the drum. Finally, after being screened by a screening machine, it can enter the subsequent treatment process.

[0004] Since clay contaminated soil contains more water than conventional soil, it is more likely to clump after being piled up. If the clay is directly transported to the drum of the scrubbing mechanism for cleaning, the clumps of clay will not be in sufficient contact with the washing liquid and will require a long period of stirring to disperse, which increases the repair time and affects the repair effect.

[0046] like Figure 1-18 As shown, in one embodiment of the present invention, a vehicle-mounted integrated soil washing and remediation device is provided, including a frame 10, a box body 20, a material frame 30, a cutting piece 40, a first driving mechanism 50, a second driving mechanism 60, a scrubbing mechanism 70, a spraying mechanism and a screening mechanism 80.

[0047] The box 20, the scrubbing mechanism 70 and the screening mechanism 80 are all mounted on the frame 10. The box 20 is provided with a feed port and a discharge port 21, which are arranged in a staggered manner. The top and bottom of the material frame 30 are both open, and a bottom plate 31 is hinged on the material frame 30. The bottom plate 31 can open or close the bottom opening of the material frame 30. The material frame 30 has a loading position in the box 20 (see Figure 3 ), cutting position (see Fig.11 ) and discharge position (see Fig.16 ). When the material frame 30 is in the loading position or the slitting position, the bottom plate 31 is in a closed state. When the material frame 30 is in the discharging position, the bottom plate 31 is in an open state, and the material frame 30 is located above the discharging port 21.

[0048] The slitting piece 40 is arranged in the box body 20, and is used to slitting the clay in the material frame 30 when the material frame 30 is in the slitting position. The first driving mechanism 50 is used to drive the slitting piece 40 to extend into the material frame 30, or to withdraw from the material frame 30. The second driving mechanism 60 is used to drive the material frame 30 to move to the loading position, the slitting position, or the discharging position. The spraying mechanism is arranged in the box body 20, and is used to spray the elution liquid so that the clay material lump after slitting is mixed with the elution liquid and then enters the scrubbing mechanism 70.

[0049] The scrubbing mechanism 70 is connected to the discharge port 21. The scrubbing mechanism 70 is used to clean the clay, and the screening mechanism 80 is used to screen the mud after scrubbing. The scrubbing mechanism 70 and the screening mechanism 80 are both existing technologies and will not be described in detail in this embodiment.

[0050] After the conveying mechanism (not shown in the figure) conveys the sticky contaminated soil to the feed port, the clay will fall into the material frame 30 at the loading position. Subsequently, the second driving mechanism 60 will drive the material frame 30 to move from the loading position to the cutting position, and the first driving mechanism 50 will drive the cutting piece 40 to extend into the material frame 30, thereby cutting the clay in the material frame 30 into smaller lumps. Then, the first driving mechanism 50 drives the cutting piece 40 to exit the material frame 30, and the second driving mechanism 60 drives the material frame 30 to move from the cutting position to the discharge position. During this process, the bottom plate 31 gradually opens the bottom opening of the material frame 30, and the clay cut into lumps will fall into the discharge port 21, and enter the scrubbing mechanism 70 after mixing with the spray liquid.

[0051] The scrubbing mechanism 70 can disperse, stir and wash the soil, so that the eluent is fully in contact with the eluent in the drum of the scrubbing mechanism 70 , and finally, after being screened by the screening mechanism 80 , the soil can enter the subsequent processing steps.

[0052] The present embodiment discloses a vehicle-mounted integrated soil leaching and remediation device, which designs a cutting piece 40 in a box body 20. The cutting piece 40 can cut the sticky contaminated soil in the material frame 30 into smaller lumps. In this way, the cut sticky contaminated soil can come into more sufficient contact with the leaching liquid after entering the drum of the scrubbing mechanism 70 along with the leaching liquid, thereby shortening the scrubbing time of the sticky contaminated soil and improving the remediation efficiency of the sticky contaminated soil.

[0053] In one embodiment, the slitting piece 40 includes a frame 41 and a plurality of cutting wires 42. The frame 41 is connected to a first driving mechanism 50. The first driving mechanism 50 uses two hydraulic cylinders. The plurality of cutting wires 42 are arranged in an interlaced manner in the frame 41. The frame 41 and the material frame 30 are both rectangular structures. The inner size of the frame 41 is larger than the outer size of the material frame 30. The side plate of the material frame 30 is provided with a plurality of notches 32. The notches 32 penetrate the top of the side plate of the material frame 30. Each notch 32 corresponds to a cutting wire 42. The frame 41 is provided with four arms. The ears on each arm are matched with the box body 20 in a vertical sliding manner.

[0054] The cutting wires 42 can be made of metal, and a plurality of cutting wires 42 are arranged in a staggered manner to form a plurality of rectangular holes. When the material frame 30 is located at the cutting position, the first driving mechanism 50 drives the frame 41 to descend. Since a notch 32 is provided on the side plate of the material frame 30, the cutting wires 42 can be embedded in the notch 32. Therefore, the cutting wires 42 will extend into the material frame 30, and the cutting wires 42 will cut the clay in the material frame 30 into lumps during the descending process.

[0055] During this process, the frame 41 is arranged outside the material frame 30 and will not interfere with the material frame 30. After the cutting is completed, the second driving mechanism 60 can move the material frame 30 to the discharge position. The structure design of the cutting piece 40 is simple, and it can easily cut the clay in the material frame 30 into lumps, ensuring the cutting effect of the clay in the material frame 30.

[0056] Furthermore, a first baffle 22 is provided in the box body 20, and the first baffle 22 is located above the cutting wire 42. The inner perimeter of the frame 41 is larger than the outer perimeter of the first baffle 22. When the frame 41 moves upward, the bottom surface of the first baffle 22 can abut against the cutting wire 42. A spray channel 43 is provided in the frame of the frame 41, and a plurality of first spray holes 44 connected to the spray channel 43 are provided on the inner side wall 25 of the frame 41. The spray mechanism includes a liquid inlet pipe 91, and the liquid inlet pipe 91 is connected to the spray channel 43.

[0057] After the slitting piece 40 slits the clay in the material frame 30, if there is clay accumulated on the cutting wire 42, the bottom surface of the first baffle 22 will abut against the cutting wire 42 when the first driving mechanism 50 drives the frame 41 to rise, thereby squeezing the accumulated clay, so that the clay can fall from the holes between the cutting wires 42. At the same time, by designing a plurality of first spray holes 44 on the frame 41, after the external liquid supply mechanism (not shown in the figure) inputs the eluent into the spray channel 43 through the liquid inlet pipe 91, the eluent can be sprayed out from the first spray holes 44, so that the cutting wire 42 and the first baffle 22 can be cleaned, the adhesion of clay on the cutting wire 42 and the first baffle 22 can be reduced, and the normal operation of the cutting wire 42 and the first baffle 22 can be ensured.

[0058] After the sprayed rinse liquid cleans the cutting wire 42 and the first baffle 22, it flows to the discharge port 21 and finally enters the drum of the scrubbing mechanism 70. In this way, the rinse liquid is reused and waste is avoided.

[0059] In one embodiment, two spaced support rails 23 are provided in the box body 20, and the support rails 23 extend along the moving direction of the material frame 30, and the two support rails 23 support the bottom plate 31 and the material frame 30. When the material frame 30 moves from the slitting position to the discharge position, the second drive mechanism 60 provides support for the material frame 30, and the bottom plate 31 gradually separates from the support rails 23 and opens the bottom opening of the material frame 30, so that the clay after slitting will fall into the discharge port 21. After the discharge is completed, when the material frame 30 moves from the discharge position to the slitting position, the support rails 23 resist the bottom plate 31, so that the bottom plate 31 gradually closes the bottom opening of the material frame 30. This structural design can realize the automatic opening and closing of the bottom plate 31, without the need to design an additional drive mechanism to drive the bottom plate 31 to rotate.

[0060] In one embodiment, in order to limit the bottom plate 31 , one end of the support rail 23 close to the discharge port 21 is bent downward to form a blocking portion 231 . When the bottom plate 31 fully opens the bottom opening of the material frame 30 , the bottom plate 31 can abut against the blocking portion 231 .

[0061] In one embodiment, the spray mechanism includes two first spray pipes 92, which are arranged vertically. The first spray pipes 92 are provided with a plurality of second spray holes. When the bottom plate 31 is in a fully opened state, the second spray holes face the bottom plate 31. The first spray pipes 92 are installed on the inner wall of the box body 20. The first spray pipes 92 are connected to the liquid supply mechanism. After the bottom plate 31 is opened, the eluent sprayed from the second spray holes will wash the clay attached to the bottom plate 31. The eluent after washing will eventually enter the drum of the scrubbing mechanism 70 through the discharge port 21. Of course, the spacing between the two first spray pipes 92 will not interfere with the normal opening and closing of the bottom plate 31.

[0062] In one embodiment, an inclined surface 24 is provided in the box 20, and the inclined surface 24 is located below the support rail 23. The side of the inclined surface 24 with a lower horizontal height is close to the discharge port 21. The spray mechanism includes a second spray pipe 93, which is arranged in the transverse direction. The second spray pipe 93 is connected to the liquid supply mechanism, and the second spray pipe 93 is close to the side of the inclined surface 24 with a higher horizontal height. The second spray pipe 93 is provided with a plurality of third spray holes, and the third spray holes face the inclined surface 24. The clay falling on the inclined surface 24 will be flushed into the discharge port 21 by the eluent sprayed from the second spray pipe 93, so that the eluent is reused and waste is avoided.

[0063] In one embodiment, a side wall 25 is provided in the box body 20, and the side wall 25 is close to the discharge port 21. The spray mechanism includes a third spray pipe 94, and the third spray pipe 94 is connected to the liquid supply mechanism. The third spray pipe 94 is provided with a plurality of fourth spray holes, and the fourth spray holes face the side wall 25. The washing liquid sprayed from the fourth spray holes will wash the side wall 25, so that the clay dropped from the material frame 30 is prevented from adhering to the side wall 25, and the cleanliness of the inside of the box body 20 is ensured.

[0064] In one embodiment, the repair device further includes a hopper 26 and a third driving mechanism (not shown in the figure), the hopper 26 is arranged in the feed port, and when the material frame 30 is in the loading position, the material frame 30 is located below the hopper 26. Two second baffles 27 are hinged in the hopper 26, and the two second baffles 27 are inclined. When the two second baffles 27 are closed, they are in a "V" shape.

[0065] The third driving mechanism is used to drive the two second baffles 27 to open or close. The third driving mechanism uses two hydraulic cylinders, each of which is connected to a second baffle 27. The design of the hopper 26 can temporarily store the clay delivered by the conveying mechanism. After the material frame 30 returns to the loading position, the third driving mechanism will reopen the two second baffles 27, so that the clay in the hopper 26 will fall into the material frame 30.

However, it is understood that embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this description.
