Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, and in particular to a soil environmental protection treatment and remediation device. Background Technology

[0002] In recent years, soil pollution has become increasingly severe, affecting not only industrialized areas but also farmland and residential areas to varying degrees. Major sources of soil pollution include industrial waste, heavy metal contamination, and the overuse of pesticides and fertilizers. These pollutants have severely damaged the soil's functions in climate regulation, water resource management, and food supply. Therefore, soil remediation is necessary to restore contaminated soil to its normal functional state. Because soil particles of different sizes (such as gravel, sand, silt, and clay) exhibit significantly different adsorption capacities and migration characteristics for pollutants, directly impacting the difficulty and effectiveness of remediation, soil screening is essential.

[0003] In existing technologies, when the soil to be remediated is excavated and transferred to the treatment equipment, the soil particles often stick together and clump together during the screening process, resulting in incomplete separation of soil particles of different sizes. A large amount of fine soil particles are discharged along with the coarse particles due to agglomeration, which not only affects the targeted treatment of pollutants in subsequent remediation processes, but also reduces the overall remediation efficiency. Therefore, we propose a soil environmental protection treatment and remediation device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a soil environmental treatment and remediation device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A soil environmental remediation device includes a soil feeding frame with a screening component inside. A U-shaped frame is fixedly connected to the outer wall of the soil feeding frame. A through hole is formed in the outer wall of the U-shaped frame, and a spray pipe is rotatably connected to the inner wall of the through hole. Multiple atomizing nozzles are uniformly fixed and interconnected at the bottom of the spray pipe. A stepper motor is fixedly connected to the top of the U-shaped frame, and a turntable is fixedly connected to the bottom of the output shaft of the stepper motor. An oil-free bushing is fixedly embedded in the outer wall of the turntable, and a slide rod is slidably connected to the inner wall of the oil-free bushing. A ball bearing sleeve is fixedly connected to the bottom of the slide rod, and a swing rod is slidably connected to the inner wall of the ball bearing sleeve. Both ends of the swing rod are fixedly connected to end plates, and through holes are formed in the outer walls of both end plates. The inner walls of the through holes are fixedly connected to the outer wall of the spray pipe.

[0007] Preferably, the screening assembly includes a screening cylinder, a support is fixedly connected to the outer wall of the soil feed frame, a geared motor is fixedly connected to the top of the support, one end of the output shaft of the geared motor passes through the outer wall of the soil feed frame and is fixedly connected to an annular support rod, and the outer wall of the annular support rod is fixedly connected to the inner wall of the screening cylinder, thereby screening the soil by setting the screening assembly.

[0008] Preferably, four rings are fixedly connected to the outer wall of the screening cylinder, and two support rings are sleeved on the outer wall of the screening cylinder. The support rings are located between the two rings, and the outer walls of the two support rings are fixedly connected to the inner wall of the soil feed frame. The screening cylinder is rotated by setting the rings and support rings.

[0009] Preferably, the bottom of the soil feeding frame is fixedly connected to a soil discharge pipe and a debris discharge pipe.

[0010] Preferably, the top of the U-shaped frame has a circular hole, and the inner wall of the circular hole is rotatably connected to the outer wall of the stepper motor output end.

[0011] Preferably, the bottom of the soil feeding frame is fixedly connected to four legs, one end of the spray pipe is fixedly connected to a rubber hose, one end of the rubber hose is fixedly connected to a water pump, and the water pump is connected to a water tank containing clean water or a low-concentration chemical solvent (such as a leaching agent).

[0012] Compared with the prior art, the advantages of this utility model are:

[0013] This solution utilizes a stepper motor-driven oscillating spray pipe structure to allow the atomizing nozzles to evenly spray clean water or low-concentration chemical solvents, ensuring thorough separation of particles of different sizes. This prevents fine particles from being discharged with coarse particles, guaranteeing targeted treatment in subsequent remediation processes and improving overall remediation efficiency. The reciprocating oscillation of the spray pipe expands the spraying range, ensuring uniform soil wetting. This prevents sieving blockage caused by insufficient local spraying and avoids soil mud caused by excessive local spraying, ensuring the stability of the sieving effect. At the same time, it not only effectively reduces dust and secondary air pollution but also preliminarily washes away soluble pollutants from the surface of soil particles, reducing the burden on subsequent remediation processes.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0020] Depend on Figures 1-3 As shown, a soil environmental treatment and remediation device is disclosed, including a soil feeding frame 1, four rings 3 fixedly connected to the outer wall of a screening cylinder 2, and two support rings 4 sleeved on the outer wall of the screening cylinder 2. The support rings 4 are located between the two rings 3, and the outer walls of the two support rings 4 are fixedly connected to the inner wall of the soil feeding frame 1. The support rings 4 provide a stable support point for the screening cylinder 2 and can also restrict the axial movement of the screening cylinder 2.

[0021] A U-shaped frame 8 is fixedly connected to the outer wall of the soil feed frame 1. A through hole is opened on the outer wall of the U-shaped frame 8. A spray pipe 9 is rotatably connected to the inner wall of the through hole. The spray pipe 9 can expand the spraying range by swinging, so that atomized water or solvent can be sprayed evenly onto the soil in the sieve. Multiple atomizing nozzles 10 are evenly fixed and interconnected at the bottom of the spray pipe 9.

[0022] A stepper motor 11 is fixedly connected to the top of the U-shaped frame 8. A round hole is opened on the top of the U-shaped frame 8. The inner wall of the round hole is rotatably connected to the outer wall of the output end of the stepper motor 11. A turntable 12 is fixedly connected to the bottom of the output shaft of the stepper motor 11. When the turntable 12 rotates with the stepper motor 11, it drives the slide rod 13 to rotate, which plays the role of transmitting power.

[0023] An oil-free bushing is fixedly embedded in the outer wall of the turntable 12. A slide rod 13 is slidably connected to the inner wall of the oil-free bushing. A ball bearing sleeve 14 is fixedly connected to the bottom of the slide rod 13. When the turntable 12 rotates, the slide rod 13 moves up and down along the oil-free bushing, while driving the ball bearing sleeve 14 to rotate and move.

[0024] A swing rod 15 is slidably connected to the inner wall of the ball sleeve 14. The swing rod 15 reciprocates under the drive of the ball sleeve 14, thereby driving the spray pipe 9 to swing. Both ends of the swing rod 15 are fixedly connected to end plates 16. The outer walls of the two end plates 16 are provided with through holes, and the inner walls of the through holes are fixedly connected to the outer walls of the spray pipe 9.

[0025] The bottom of the soil feed frame 1 is fixedly connected with a soil discharge pipe 7 and a debris discharge pipe 17. The debris discharge pipe 17 is used to discharge impurities (such as stones, plastic fragments, etc.) separated during the screening process, which facilitates the centralized collection and treatment of impurities.

[0026] The bottom of the soil feed frame 1 is fixedly connected to four legs. One end of the spray pipe 9 is fixedly connected to a rubber hose, and the other end of the rubber hose is fixedly connected to a water pump. The rubber hose has good flexibility and can be flexibly deformed with the swing of the spray pipe 9 without restricting the swing of the spray pipe 9.

[0027] The soil feed frame 1 is equipped with a screening component inside, which includes a screening cylinder 2. The screening cylinder 2 performs a screening operation on the soil by rotating. A support is fixedly connected to the outer wall of the soil feed frame 1. A geared motor 5 is fixedly connected to the top of the support. One end of the output shaft of the geared motor 5 passes through the outer wall of the soil feed frame 1 and is fixedly connected to an annular support rod 6. The outer wall of the annular support rod 6 is fixedly connected to the inner wall of the screening cylinder 2. The annular support rod 6 effectively transmits the driving force of the geared motor 5 to the screening cylinder 2, causing the screening cylinder 2 to rotate synchronously.

[0028] Working principle: During use, the soil to be repaired is excavated and transferred into the soil feed frame 1, located inside the screening cylinder 2. As the reduction motor 5 operates, it drives the annular support rod 6 to rotate, which in turn drives the screening cylinder 2 to rotate. Four circular rings 3 and two support rings 4 assist in the stable rotation of the screening cylinder 2. During this process, a water pump operates to deliver clean water or low-concentration chemical solvents (such as leaching agents) to the spray pipe 9. Multiple atomizing nozzles 10 at the bottom of the spray pipe 9 then spray atomized water downwards. The stepper motor 11 operates, driving the turntable 12 to rotate, which in turn drives the sliding rod 13 to rotate. As the ball bearing sleeve 14, which is fixedly connected to the bottom of the sliding rod 13, rotates, it moves along the swing arm... The moving rod 15 moves, and during the rotation, the sliding rod 13 moves up and down along the oil-free bushing. After the ball bearing sliding sleeve 14 rotates, it drives the swing rod 15 and the two end plates 16 to swing back and forth, thereby driving the swing rod 15 to swing back and forth, which in turn drives the spray pipe 9 to swing, so as to spray evenly onto the soil in the sieving process. Spraying can moisten the soil particles, reduce the adsorption force between the particles, loosen the clumps of soil, and facilitate the separation of particles of different sizes through the sieving cylinder 2. It can also reduce dust in the sieving process and initially remove soluble pollutants (such as some heavy metal ions and easily soluble organic matter) attached to the soil particles, which is a pretreatment for subsequent remediation (such as leaching remediation and bioremediation).

[0029] It should be noted that when actually put into use, an existing PLC controller can be added. The PLC controller is electrically connected to the geared motor 5 and the stepper motor 11 to facilitate the control of the overall operation.
