Description

Technical Field

[0001] This invention relates to the field of soil remediation technology, specifically to an in-situ ecological remediation device for contaminated soil. Background Technology

[0002] Environmental pollution has always been a hot topic of global concern and a major challenge facing all of humanity. Soil is the primary accumulation site for various pollutants in the environment. Strengthening soil pollution prevention and control and improving soil environmental quality are important parts of building an ecological security system and are also a requirement for the development of environmental science and technology. Soil ecological restoration devices are needed in soil remediation, such as those described in patent publication number CN 113477701. Patent B describes an urban soil ecological restoration device in which the cross-sectional edges of the first, second, and third guide rings are all right-angled triangles, with the right-angled sides fitting against the inner wall of the restoration tank. The diameter of the first guide ring is smaller than the diameter of the umbrella-shaped plate, which facilitates soil entry into the restoration tank and prevents soil residue from remaining on the edges of the first, second, and third guide rings. Simultaneously, the smaller diameter of the first guide ring ensures that the soil is completely covered by the umbrella-shaped plate when passing through the third guide ring. A spray assembly is included, so that when the soil passes through the screen of the feeding assembly, the shaking of the screen causes the soil to fall evenly onto the umbrella-shaped plate. The inclined nozzles ensure that the outer side of the umbrella-shaped plate is evenly coated with the restoration solution, allowing for uniform contact of the restoration solution with the soil upon contact with the umbrella-shaped plate, thereby improving restoration efficiency.

[0003] However, when this device remediates soil, it first transports the soil to be remediated to the remediation base, dries and crushes the soil, and then adds a remediation solution to the crushed soil. The remediation solution then repairs the soil. This soil transportation process makes the remediation process more complicated, consumes more resources, and makes soil remediation untimely.

[0004] Based on this, an in-situ ecological remediation device for contaminated soil is now provided, which can eliminate the drawbacks of existing devices. Summary of the Invention

[0034] In one embodiment, such as Figure 1 and Figure 4As shown, the material handling mechanism 200 includes a lifting cylinder 201 with threads on its surface. The side of the lifting cylinder 201 is fixedly connected to the inner wall of the mounting plate 100 via a limiting block 214. The lifting cylinder 201 is threadedly fitted with a threaded sleeve 202. A soil-turning assembly 600 is fixedly connected to the side of the lifting cylinder 201. The threaded sleeve 202 is rotatably mounted on the inner wall of the mounting plate 100. A rotating shaft 203 is rotatably mounted on the top surface of the mounting plate 100.

A damping component 900 is fixedly installed at the connection with the slide bar 209. In use, the first motor 207 is started, and the first transmission belt 205 drives the rotating shaft 203 to rotate, so that the gear 204 drives the threaded sleeve 202 to rotate. Thus, under the action of the thread on the surface of the lifting cylinder 201, the lifting cylinder 201 and the soil turning component 600 are lowered together to contact the ground. Under the action of the damping component 600, the lifting cylinder 201 is locked, and the first motor 207 continues to drive the spiral blade 213 to rotate and transport the soil sample upward.

[0035] In one embodiment, such as Figure 7 As shown, the crushing mechanism 300 includes a support plate 301. A second support frame 302 for supporting a second motor 303 is fixedly provided at the top of the support plate 301. A crushing shaft 304 is fixedly connected to the output end of the second motor 303. Crushing blades 305 for crushing are fixedly provided on the side of the crushing shaft 304. The bottom surface of the drying and crushing box 105 is provided with a discharge port 306 for discharging the dried and crushed soil sample. The sampled soil sample enters the drying and crushing box 105 through the discharge pipe 208 and the inlet 106. The second motor 303 is started, which causes the crushing shaft 304 to drive the crushing blades 305 to rotate and crush the soil sample. The crushed soil sample falls onto the conveyor belt 103 through the discharge port 306 and is conveyed backward for repair.

[0036] In one embodiment, such as Figure 6 and Figure 8 As shown, the repair mechanism 400 includes a liquid tank 401, which is fixedly mounted on the drying and pulverizing chamber 105. A liquid outlet pipe 402 is fixedly connected to the side of the liquid tank 401. A spray head 403 for spraying repair liquid is fixedly mounted on the bottom surface of the liquid outlet pipe 402. An adjusting component 700 for adjusting the liquid output is fixedly mounted inside the spray head 403. A mounting box 404 is fixedly mounted on the side of the drying and pulverizing chamber 105. A first connecting rod 405 is connected to the mounting box 404 via a reciprocating component 800. A digging block 406 for removing soil is fixedly mounted on the bottom surface of the first connecting rod 405. The reciprocating assembly 800 is connected to the crushing shaft 304 via the second transmission belt 407, and the adjusting assembly 700 is connected to the reciprocating assembly 800 via the third transmission belt 408. The soil sample, after being dried and crushed in the drying and crushing box 105, falls onto the conveyor belt 103, which transports the soil sample backward. Under the action of the second motor 303, the reciprocating assembly 800 is driven by the second transmission belt 407, causing the reciprocating assembly 800 to move back and forth, spreading the soil sample evenly. The adjusting assembly 700 is driven by the third transmission belt 408 to rotate and control the amount of repair liquid sprayed, so that the soil sample and repair liquid are evenly mixed.

[0037] In one embodiment, such as Figure 6 As shown, the adjustment assembly 700 includes an adjustment shaft 701, which is rotatably mounted on the inner wall of the spray head 403. A third transmission belt 408 is fixedly mounted on the top of the adjustment shaft 701, and a rotating plate 702 is fixedly mounted on the side of the adjustment shaft 701. A discharge hole 703 is opened on the bottom surface of the spray head 403. Under the action of the second motor 303, the adjustment shaft 701 is driven to rotate through the third transmission belt 408, which in turn drives the rotating plate 702 to rotate. When the rotating plate 702 is horizontal, the liquid output is minimal, and when the rotating plate 702 is vertical, the liquid output is maximum.

[0038] In one embodiment, such as Figure 8 As shown, the reciprocating assembly 800 includes a screw 801, which is rotatably mounted on the inner wall of the mounting box 404. The screw 801 is connected to the crushing shaft 304 via a second transmission belt 407, which is fixedly sleeved on the top of the screw 801. A threaded block 802 is threaded onto the screw 801. The first connecting rod 405 is fixedly mounted on the bottom surface of the threaded block 802. Under the action of the second motor 303, the screw 801 is driven to rotate via the second transmission belt 407, causing the threaded block 802 to drive the agitator block 406 to move back and forth, thus evenly spreading the soil sample.

[0039] In one embodiment, such as Figure 9As shown, the vibration mechanism 500 includes a toggle plate 501, which is fixedly mounted on the side of the screen 108. A fixing block 502 is fixedly mounted on the side of the fixing plate 104. A toggle rod 503 is slidably mounted inside the fixing block 502. The top surface of the toggle rod 503 contacts the bottom surface of the toggle plate 501. A baffle 504 is fixedly mounted on the side of the toggle rod 503. A first spring 505 is fixedly mounted on the bottom surface of the baffle 504. The other end of the first spring 505 is connected to the fixing block 502. The top surface is fixedly connected, and the bottom surface of the actuating rod 503 is fixedly provided with a pressure wheel 506. The pressure wheel 506 contacts the protrusion 102 on the surface of the wheel 101. When the wheel 101 rotates, the protrusion 102 will generate a pushing force on the pressure wheel 506, thereby causing the baffle 504 to generate an upward pushing force. With the reset of the first spring 505, the actuating rod 503 will move up and down reciprocally. The actuating rod 503 will generate a pushing force on the actuating plate 501, thereby causing the screen 108 to vibrate.

[0040] In one embodiment, such as Figure 5 As shown, the soil turning assembly 600 includes a second connecting rod 601, which is fixedly connected to the side of the lifting cylinder 201. A blade holder 602 is fixedly provided at the top of the second connecting rod 601, and a soil turning blade 603 for turning soil is fixedly provided on the bottom surface of the blade holder 602. When the device moves forward, the soil turning blade 603 will turn the soil sample.

[0041] In one embodiment, such as Figure 10 As shown, the damping assembly 900 includes a first protrusion 901, which is fixedly disposed on the side of the spiral blade 213. The first protrusion 901 engages with a second protrusion 902, which is fixedly disposed on the damping groove 903. The inner wall of the damping groove 903 is provided with a second spring 904. When the collecting plate 215 contacts the ground, under the action of the second spring 904, the second protrusion 902 exerts a force on the first protrusion 901, thereby locking the lifting cylinder 201.

[0042] The above embodiment discloses an in-situ ecological remediation device for contaminated soil. In use, the first motor 207 is started, driving the rotating shaft 203 to rotate via the first transmission belt 205. This causes the gear 204 to drive the threaded sleeve 202 to rotate, thereby causing the lifting cylinder 201, along with the turning blade 603, to descend to contact the ground. When the collecting plate 215 contacts the ground, the second spring 904 causes the second protrusion 902 to exert force on the first protrusion 901, locking the lifting cylinder 201. The first motor 207 continues to drive the spiral blades 213 to rotate and transport the soil sample upwards. The soil sample then enters the drying and pulverizing box 105 through the discharge pipe 208 and the inlet 106. The second motor 303 is started, causing the pulverizing shaft 304 to drive the pulverizing blades 305 to rotate, pulverizing the soil sample. The pulverized soil sample is then discharged through the discharge pipe. The soil sample 306 falls onto the conveyor belt 103 and is conveyed backward. Under the action of the second motor 303, the screw 801 rotates via the second conveyor belt 407, causing the threaded block 802 to move back and forth along the actuating block 406, spreading the soil sample evenly. The adjusting shaft 701 rotates via the third transmission belt 408, which in turn rotates the rotating plate 702. When the rotating plate 702 is horizontal, the liquid output is minimal; when the rotating plate 702 is vertical, the liquid output is maximum, thus evenly mixing the soil sample and the repair liquid. When the wheel 101 rotates, the protrusion 102 pushes the pressure wheel 506, causing the baffle 504 to generate an upward pushing force. Combined with the reset of the first spring 505, the actuating rod 503 moves up and down reciprocally. The actuating rod 503 pushes the actuating plate 501, causing the screen 108 to vibrate, so that the repaired soil sample is evenly spread on the ground.

[0043] The above description is merely a specific embodiment of this disclosure, but the scope of protection of this disclosure is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this disclosure should be included within the scope of protection of this disclosure. Therefore, the scope of protection of this disclosure should be determined by the scope of the claims.
