Description

Technical Field

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

[0002] Soil remediation is a technical measure to restore the normal function of contaminated soil. In the soil remediation industry, existing soil remediation technologies can be roughly divided into three methods: physical, chemical and biological. Among them, the chemical method mainly relies on the discharge of remediation fluid.

[0003] In the process of using repair fluid to repair soil, the correct amount of repair fluid is related to the entire repair process. Excessive use of repair fluid will not only fail to improve the repair efficiency, but also increase secondary pollution and repair costs. Using too little repair fluid will directly affect the repair effect. The compactness of the soil is directly reflected in the amount of repair fluid. Soil with high compactness usually has low porosity and complex pore structure, resulting in a large extrusion pressure between soil particles. Excessive extrusion pressure will cause the soil to have a large resistance to water flow, which means that the repair fluid will encounter greater resistance when passing through soil with high compactness, which will affect the penetration and distribution of the repair fluid. Therefore, a relatively larger amount of repair fluid is required. However, the amount of repair fluid is still judged based on the experience of the staff, which makes it difficult to accurately apply the amount of repair fluid, which has a great impact on the quality of soil remediation.

[0036] The lower end side wall of the soil-inserting repair mechanism 4 is also symmetrically provided with a plurality of groups of vibrating loosening mechanisms 8, which include a plurality of vibrating blocks 81, and the lower end side wall of the insertion tube 42 is provided with a plurality of embedding grooves 82 corresponding to the positions of the vibrating blocks 81, and the inner walls of the embedding grooves 82 are symmetrically fixedly connected with a plurality of fixed slide rods 83, one end of the fixed slide rods 83 is fixedly connected with a locking plate 84, and the outer sliding sleeves of the plurality of fixed slide rods 83 are connected with the same force-bearing plate 85, and the vibrating blocks 81 are fixedly connected to the side walls of the force-bearing plate 85, and the bottom of the embedding grooves 82 is fixedly connected with a plurality of alternating electromagnetic plates 86, and the side walls of the force-bearing plate 85 are fixedly connected with a plurality of force-bearing permanent magnet plates 87 corresponding to the positions of the alternating electromagnetic plates 86.

[0037] The soil insertion repair mechanism 4 is also provided with a soil compactness sensing feedback mechanism 9, which is electrically connected to the second lifting mechanism 5, the liquid supply amount self-sensing control mechanism 7 and the vibration loosening mechanism 8 respectively. The soil compactness sensing feedback mechanism 9 includes a feedback sleeve 91 fixedly connected to the upper end of the fixed support plate 44, and the feedback sleeve 91 is covered on the outside of one of the anti-slip plates 46. The two sides of the anti-slip plate 46 are respectively fixedly connected with a liquid supply conductive contact 92 and an insertion conductive contact 93. The inner wall of the feedback sleeve 91 is fixedly connected to the upper end of the fixed support plate 44.

The upper end of the feedback housing 91 is also symmetrically provided with a plurality of sleeve holes, and compensation rods 96 are movably inserted into the corresponding sleeve holes. The lower ends of the plurality of compensation rods 96 are fixedly connected with the same starting switch 97, and the upper end of the starting switch 97 and the top of the inner wall of the feedback housing 91 are fixedly connected with a plurality of compensation springs 98 sleeved outside the compensation rods 96.

[0038] A controller 10 is also fixedly installed on the upper end of the supporting frame 1. The controller 10 can adopt a PLC controller. The translation mechanism 2, the soil surface leveling and repairing mechanism 3, the soil inserting and repairing mechanism 4, the second lifting mechanism 5, the repairing liquid storage and supply mechanism 6, the liquid supply amount self-sensing and regulating mechanism 7, the vibration loosening mechanism 8 and the soil compactness sensing and feedback mechanism 9 are all electrically connected to the PLC controller 10.

[0039] The operating principle of the present invention is described as follows: the support frame 1 is used to move the entire equipment to the soil that needs to be repaired. The PLC controller 10 first pushes the mounting plate 32 downward through the first lifting mechanism 31, so that the lower end of the scraper 35 extends into the soil surface by 10 cm, and then the reciprocating screw drive assembly 21 is started. The reciprocating screw drive assembly 21 drives the reciprocating seat 22 to drive the scraper 35 to move horizontally. The reciprocating screw drive assembly 21 here is that the motor drives the reciprocating screw to rotate to achieve the adjustment of the linear displacement. It is a prior art and will not be described in detail. The scraper 35 turns the soil surface during the horizontal movement, and in this process, the delivery pump 65 is started, and the solenoid valve 64 on the dispensing pipe 63 is opened. The dispensing pipe 63 delivers the repair liquid in the storage box 61 to the surface repair nozzle 310 for spraying, and the repair liquid is sprayed on the soil surface after turning over. After moving to the front side, it moves in the reverse direction, and the rear side of the scraper 35 is used to level the soil surface. When turning the soil, large-diameter stone impurities fall on the scraper 35, which can automatically process the soil surface, remove the stone impurities on the soil surface, and level the soil surface, and spray the repair liquid synchronously to ensure the quality of the soil surface repair treatment. When a large amount of stone impurities are attached to the scraper 35 or a large volume of stone impurities is encountered, making it difficult for the scraper 35 to move forward, the elastic force of the strong pulling spring 37 under the continued movement of the reciprocating seat 22 cannot drive the scraper 35 to move forward, so that the scraper 35 overcomes the elastic force of the strong pulling spring 37 and moves backward along the guide slide bar 34, so that the upper end of the scraper 35 acts on the warning switch 38, and the warning switch 38 triggers the alarm 39 to work, reminding the staff to carry and process these stone impurities in time;

[0040] After the soil surface is treated and leveled, the support rod frame is moved forward so that the insertion tube 42 moves to the treated soil surface. The PLC controller 10 controls the power supply device to supply power to the power electromagnetic plate 54. The power electromagnetic plate 54 is energized to generate magnetism and cooperate with the power permanent magnet plate 53 to drive the lifting plate 52 to drive the lifting rod 41 to move downward. The lifting rod 41 drives the insertion tube 42 to move downward relatively through the action of the feedback spring 47, so that the lower end of the insertion tube 42 is inserted into the soil at 0.8m. The PLC controller 10 then starts the delivery pump 65 and simultaneously opens the solenoid valve 64 on the infusion tube 62, so that the infusion tube 62 is connected, and cooperates with the infusion tube 62 to deliver the repair liquid to the infusion channel 411 and the annular buffer cavity 48 in the insertion tube 42, and the repair liquid seeps out through multiple seepage tubes 49, which can quickly act on the inside of the soil with the repair liquid.

[0041] When the insertion tube 42 moves downward and is inserted into the soil, the distance that the insertion tube 42 moves upward relative to the lifting rod 41 to overcome the elastic force of the feedback spring 47 is different due to the different soil compactness. Specifically, the higher the soil compactness, the greater the distance that the insertion tube 42 moves upward relative to the lifting rod 41, which is reflected in the greater distance that the limit vertical rod 45 drives the anti-slip plate 46 to move upward. When the anti-slip plate 46 moves upward relatively, it drives the liquid supply conductive contact piece 92 and the insertion conductive contact piece 93 to move upward synchronously, wherein the liquid supply conductive contact piece 92 and the liquid supply conductive contact piece 93 are The rod 94 is connected in series to the power supply circuit of the reduction motor 73. When the repair liquid is delivered to the insertion tube 42, the reduction motor 73 is started. The reduction motor 73 drives the arc-shaped pressing block 75 to move in the regulating circular shell 71 through the rotating shaft 72 and the connecting rod 74. During the process of the arc-shaped pressing block 75 being separated from the power-off switch 76, the delivery pump 65 is actuated to deliver the repair liquid. When the arc-shaped pressing block 75 acts on the power-off switch 76, the power-off switch 76 feeds back a signal to the PLC controller 10, and the PLC controller 10 controls the delivery pump 65. The delivery pump 65 stops working, and the reduction motor 73 stops working synchronously. When the soil density is higher, the upward movement distance of the anti-slip plate 46 is greater, and the moving distance of the liquid supply conductive contact 92 on the liquid supply resistor rod 94 is greater, and the resistance value of the liquid supply resistor rod 94 connected to the power supply circuit of the reduction motor 73 is greater, and the power supply low voltage of the reduction motor 73 is smaller. Since the reduction motor 73 is a DC motor, the smaller the power supply voltage means the slower the rotation speed of the reduction motor 73, and the longer the arc pressing block 75 is separated from the power off switch 76, the longer the working time of the delivery pump 65, and the more the delivery pump 65 delivers the repair liquid of the insertion tube 42. On the contrary, the smaller the soil density is, the smaller the upward movement distance of the anti-slip plate 46 is, and the less the delivery pump 65 delivers the repair liquid of the insertion tube 42. The amount of repair liquid can be automatically adjusted based on the density of the soil to ensure that the amount of repair liquid is always at an appropriate level, ensure the repair quality, and avoid the problem of secondary pollution caused by excessive repair liquid and increased repair cost.

[0042] The upward movement of the anti-slip plate 46 synchronously drives the insertion conductive contact 93 to move upward relative to the insertion resistor rod 95. The insertion conductive contact 93 and the insertion resistor rod 95 are electrically connected to the power supply circuit of the power electromagnetic plate 54. The greater the soil density, the greater the upward movement distance of the insertion conductive contact 93, which makes the access resistance of the insertion resistor rod 95 smaller, and the power supply current of the power electromagnetic plate 54 larger, which increases the downward movement distance of the lifting rod 41. It can automatically compensate for the problem that the insertion tube 42 moves upward relative to the lifting rod 41 due to the problem of excessive soil density, which leads to the problem of insufficient insertion depth of the insertion tube 42, thereby ensuring the effect quality of the repair liquid;

[0043] When the soil density reaches 1.5 g / cubic centimeter, it indicates that the current soil quality makes it difficult for the repair liquid to penetrate, which has a great impact on the repair quality of the repair liquid. At this time, the anti-slip plate 46 moves up a large distance along with the limit vertical rod 45, so that the anti-slip plate 46 can act on the start switch 97. After the start switch 97 is pressed, a feedback signal is given to the PLC controller 10. The PLC controller 10 drives the external power supply equipment to transmit alternating power to the alternating electromagnetic plate 86, so that the alternating electromagnetic plate 86 produces cyclic positive and negative magnetism. In conjunction with the force-bearing permanent magnet plate 87, what is displayed is that the vibration block is driven to move back and forth quickly along the fixed slide bar 83, and then the coating at the treatment point of the repair liquid is quickly vibrated and loosened. It can automatically sense the soil density and perform vibration and loosening operations when the soil density is reached, so as to ensure the penetration performance of the repair liquid and improve the repair quality.
