Description

Technical Field

[0001] The utility model belongs to the technical field of soil remediation, and specifically relates to a contaminated soil remediation device. Background Art

[0002] With the continuous acceleration of the industrialization process, the unreasonable exploitation of mineral resources, the discharge of machine smelting, the long-term sewage irrigation and sludge application to the soil, the atmospheric deposition caused by human activities, the application of fertilizers and pesticides have caused serious soil pollution. At the same time, it will enter the human body through the food chain and cause harm to human health. Therefore, soil restoration and regeneration is particularly important. The existing restoration is divided into physical restoration, chemical restoration, and biological restoration. Among them, chemical restoration is to spray chemical agents with restoration and regeneration on the soil. After the soil absorbs it, it gradually restores its normal function. However, direct spraying causes the surface soil to absorb it, but the internal soil cannot absorb it, causing its unevenness.

[0003] When repairing the soil, a soil repair device is needed. For example, Chinese utility model patent CN212682034U discloses a contaminated soil repair device. First, a repair liquid (a solution known to those skilled in the art) is added to the first liquid storage cylinder and the second liquid storage cylinder. Then, the punching cylinder is started. Driven by the punching cylinder, the connecting plate is pressed down and the ejector pin is pressed down together and extended into the soil. Then, by controlling the one-way valve, the repair liquid in the first liquid storage cylinder and the second liquid storage cylinder flows into the connecting plate from the first guide column and the second guide column respectively, and then the drainage groove line of the grid structure in the connecting plate passes through the through hole to connect it. The drainage groove connected to the ejector pin allows the repair liquid to slowly penetrate into the soil. A sprinkler head can be installed on half of the connecting plate and an ejector pin can be installed on the other half, so that it can spray on the upper surface of the soil and penetrate into the lower layer of the soil, thereby improving work efficiency. The ejector pin is driven into the soil by a stamping cylinder, and then the repair liquid is input into the soil through the drainage groove on the ejector pin. The structure is simple and the work efficiency is high. At the same time, different places can be repaired through the crawler structure, which is easy to operate and can greatly improve its work efficiency. In addition, the ejector pin can be replaced to spray on the surface of the soil, thereby reducing the need to replace equipment and achieving the purpose of reducing costs.

[0004] Although the above-mentioned prior art can reduce costs, when the repair liquid is sprayed on the soil, the soil is easy to enter the interior of the ejector pin from the drainage groove, and the drainage groove is easy to be blocked after a long period of repair work, which requires manual cleaning, which is extremely inconvenient.

Some simplifications or omissions may be made in this section and the specification abstract and utility model name of this application to avoid blurring the purpose of this section, specification abstract and utility model name, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0006] To solve the above problems, the utility model adopts the following technical solutions.

[0007] A contaminated soil remediation device comprises a mounting bracket, a liquid storage tank which can move up and down is mounted above the mounting bracket, a plurality of insertion rods are mounted at the bottom of the liquid storage tank, a plurality of connecting holes are arranged at the bottom of the liquid storage tank, a pressurizing mechanism is mounted on the liquid storage tank, each insertion rod is hollow inside and has an opening at the upper end, the opening of the insertion rod is opposite to the connecting hole, a plurality of drainage grooves are arranged on the outer wall of the insertion rod, a sealing plate is arranged at each drainage groove, the sealing plate moves outward when the remediation liquid is sprayed, and automatically resets when the remediation liquid is not sprayed.

[0008] Preferably, the interior of the insertion rod is connected with a connecting hollow tube, the upper end of the connecting hollow tube is provided with a liquid inlet opposite to the connecting hole, the outer wall of the connecting hollow tube is provided with multiple liquid outlet holes, and the connecting hollow tube reduces the volume inside the insertion rod and increases the pressure of the repair liquid sprayed out.

[0009] Preferably, the outer wall connecting the upper and lower sides of the hollow tube is provided with a plurality of sliding holes, and the outer walls at both ends of the hollow tube are provided with a plurality of sliding holes, each sliding hole is slidably connected to a sliding rod, and a reset spring is connected between each sliding rod and the inside of the sliding hole, and the ends of every two vertically opposite sliding rods are fixedly connected to a sealing plate, and each sealing plate blocks each drainage groove. The compressor pressurizes the repair fluid so that the repair fluid enters the interior of the hollow tube through the liquid inlet, and then sprays out from the liquid outlet hole connected to the outer wall of the hollow tube. As the pressure increases, each sealing plate moves outward and stretches the reset spring. After the spraying is completed, the resilience of each reset spring causes the sealing plate to reset and continue to seal the drainage groove.

[0010] Preferably, the pressurizing mechanism includes a compressor, which is installed at the upper end of the liquid storage tank. The air outlet of the compressor is connected to the interior of the liquid storage tank. A liquid filling port is provided on one side of the upper end of the liquid storage tank. When the compressor works, it pressurizes the external air and blows it into the interior of the liquid storage tank.

[0011] Preferably, sliding rails are fixedly connected to both sides of the upper end of the mounting bracket, and a connecting top plate is fixedly connected to the upper ends of the sliding rails on both sides, and sliding blocks are fixedly connected to the outer walls of both sides of the liquid storage tank for sliding connection, and the upper end of the connecting top plate is detachably connected to an electric telescopic rod, and the telescopic end of the electric telescopic rod passes through the connecting top plate and is detachably connected to the upper end of the liquid storage tank, and the liquid filling port and the compressor pass through the connecting top plate. The electric telescopic rod is extended so that the liquid storage tank moves downward inside the sliding rails on both sides through the sliding blocks on both sides, thereby allowing each insertion rod to be inserted into the soil.

[0012] Preferably, an insertion tip is fixedly connected to the bottom of the insertion rod, and the insertion tip makes it easier for the insertion rod to be inserted into the soil.

[0013] Preferably, two ends of the mounting bracket are rotatably connected to transmission rods, and two ends of the transmission rods on both sides pass through the mounting bracket and are detachably connected to rolling wheels.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. By setting the blocking plate, the repair liquid can be stored inside the insertion rod without leaking out when the repair liquid is not sprayed. When the repair liquid is sprayed, the compressor pressurizes the repair liquid so that it enters the inside of the connected hollow tube through the liquid inlet, and then sprays out from the liquid outlet connected to the outer wall of the hollow tube. As the pressure increases, each blocking plate moves outward and stretches the reset spring. After the spraying is completed, the rebound force of each reset spring resets the blocking plate to continue to block the drainage groove, thereby preventing soil from entering the inside of the insertion rod. In addition, by connecting the hollow tube, the space inside the insertion rod becomes smaller, so that the spraying pressure of the repair liquid is greater.

[0016] 2. The insertion tip makes it easier to insert the insertion rod into the soil. The opening above the insertion rod allows the repair liquid to enter the interior of the insertion rod and finally spray outward through the drainage groove. The multiple drainage grooves allow the soil around each insertion rod to contact the repair liquid, resulting in a better repair effect. BRIEF DESCRIPTION OF THE DRAWINGS

The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0029] like Figure 1 As shown, it is a schematic structural diagram of a contaminated soil remediation device according to a preferred embodiment of the utility model. The contaminated soil remediation device of this embodiment includes a mounting bracket 100, on which a liquid storage tank 200 that can move up and down is installed. The liquid storage tank 200 stores remediation liquid inside, and a plurality of insertion rods 300 are detachably connected to the bottom of the liquid storage tank 200. In this embodiment, the liquid storage tank 200 moves downward so that each insertion rod 300 is inserted into the soil and the remediation liquid is sprayed into the soil to remediate the soil.

[0030] like Figure 2 as well as Figure 3As shown, it is a schematic diagram of the mounting bracket and the liquid storage tank structure in this embodiment, the upper ends of the mounting bracket 100 are fixedly connected with sliding rails 103, the upper ends of the sliding rails 103 on both sides are fixedly connected with connecting top plates 104, the outer walls on both sides of the liquid storage tank 200 are fixedly connected with sliding blocks 202 slidably connected to the sliding rails 103 on both sides, the upper end of the connecting top plate 104 is detachably connected with an electric telescopic rod 105, the telescopic end of the electric telescopic rod 105 passes through the connecting top plate 104 and is detachably connected to the upper end of the liquid storage tank 200, in this embodiment, the electric telescopic rod 105 is extended so that the liquid storage tank 200 moves downward inside the sliding rails 103 on both sides through the sliding blocks 202 on both sides, thereby allowing each insertion rod 300 to be inserted into the soil.

[0031] like Figure 2 As shown, in order to enable the mounting bracket 100 to carry the liquid storage tank 200 and the insertion rod 300 for more convenient movement, in this embodiment, the two ends of the mounting bracket 100 are rotatably connected to the transmission rod 102, and the two ends of the transmission rod 102 on both sides pass through the mounting bracket 100 and are detachably connected to the rolling wheel 101. In this embodiment, through the setting of the rolling wheel 101 and the transmission rod 102, the device can be pushed more conveniently, and then the soil can be repaired more conveniently.

[0032] like Figure 3 As shown, a liquid filling port 204 is provided on one side of the upper end of the liquid storage tank 200. The liquid filling port 204 is opened to add the repair liquid into the liquid storage tank 200. The upper end of the liquid storage tank 200 is detachably connected to a compressor 201. The liquid filling port 204 and the compressor 201 pass through the connecting top plate 104. The air outlet end of the compressor 201 is connected to the interior of the liquid storage tank 200. A plurality of connecting holes 203 are provided at the bottom of the liquid storage tank 200. Each insertion rod 300 is connected to each connecting hole 203. In this embodiment, the compressor 201 works to pressurize the external air and transport it to the interior of the liquid storage tank 200, so that the pressure inside the liquid storage tank 200 increases, and then the repair liquid inside the liquid storage tank 200 can be sprayed outward through each liquid storage tank 200, so that the pressure of the repair liquid sprayed out is higher and the coverage is wider, and the speed at which the repair liquid penetrates the soil and spreads is faster.

[0033] like Figure 4 As shown, it is a schematic diagram of the insertion rod structure in this embodiment, the outer wall of the insertion rod 300 is provided with a plurality of drainage grooves 301, and the upper end of the insertion rod 300 is provided with an opening, and the bottom of the insertion rod 300 is fixedly connected with an insertion tip 302. In this embodiment, the insertion tip 302 makes it easier for the insertion rod 300 to be inserted into the soil, and the opening above the insertion rod 300 allows the repair liquid to enter the insertion rod 300 and finally spray outward through the drainage grooves 301. By setting up a plurality of drainage grooves 301, the soil around each insertion rod 300 can contact the repair liquid, so that the repair effect is better.

In this embodiment, the blocking plate 306 can store the repair liquid inside the insertion rod 300 when the repair liquid is not sprayed and will not leak out. When the repair liquid is sprayed, the compressor 201 pressurizes the repair liquid so that it enters the interior of the connected hollow tube 303 through the liquid inlet 304, and then sprays out from the liquid outlet hole connected to the outer wall of the hollow tube 303. As the pressure increases, each sealing plate 306 moves outward and stretches the return spring 308. After the spraying is completed, the rebound force of each return spring 308 causes the sealing plate 306 to reset and continue to seal the drainage groove 301, thereby preventing soil from entering the interior of the insertion rod 300. By connecting the hollow tube 303, the space inside the insertion rod 300 becomes smaller, so that the spraying pressure of the repair liquid is greater.
