Description

Technical Field

[0001] This utility model relates to the technical field of treating contaminated soil, and in particular to a high-efficiency rinsing device for treating contaminated soil. Background Technology

[0002] In the field of environmental pollution control, soil pollution is becoming increasingly prominent, posing a major challenge to the ecological environment and public health. Polluted soil contains various harmful substances such as heavy metals and organic matter. These pollutants not only damage soil structure and reduce soil fertility, but may also enter the human body through the food chain, posing a serious threat to biodiversity and human health. Therefore, the effective treatment and remediation of polluted soil is an urgent need for environmental protection and sustainable development.

[0003] Chinese utility model patent CN218963606U discloses a rinsing device for treating heavy metal contaminated soil, including a rinsing tank. The inner walls of the rinsing tank are evenly and alternately equipped with inclined plates, which slope downwards towards the center of the rinsing tank. A filter screen is connected between the lower part of the inclined plates and the inner wall of the adjacent rinsing tank. A nozzle is installed in the rinsing tank between the connected inclined plates and the filter screen. Although this device can rinse the rolling soil, and the rinsing can reach more comprehensively as the soil moves, resulting in better rinsing and avoiding residue, during use, the rolling speed of soil particles on the inclined plates may be uneven, and some soil particles may accumulate at the bottom of the inclined plates or near the filter screen due to gravity. This results in the soil in these areas not being fully rinsed, affecting the overall rinsing efficiency and effect.

[0004] Therefore, in order to address the shortcomings of the above-mentioned problems, a high-efficiency rinsing device for contaminated soil treatment is proposed. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a high-efficiency rinsing device for treating contaminated soil.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a high-efficiency rinsing device for treating contaminated soil, comprising: a rinsing tank, a rinsing mechanism disposed within the rinsing tank, and a plurality of rinsing nozzles disposed on the inner circumference of the rinsing tank;

[0007] The rinsing mechanism includes: a rinsing frame, a rotating cylinder disposed on the inner wall of the bottom of the rinsing frame, a plurality of drainage grooves disposed on the inner circumference of the rotating cylinder, a plurality of scrapers disposed on the outer circumference of the rinsing frame, a plurality of drainage holes disposed on the inner circumference of the rinsing frame, a baffle disposed between the inner circumference of the rinsing frame and the outer circumference of the rotating cylinder, and a driving assembly disposed at the bottom of the rinsing frame.

[0008] The outer circumferential wall of the rinsing frame is fixedly connected to the inner circumferential wall of the rinsing tank. Several rinsing nozzles are fixedly installed on the inner circumferential wall of the rinsing tank, and the rinsing nozzles are distributed on the outside of the rinsing frame. Several connecting rods are fixedly connected to the outer circumferential wall of the rinsing frame, and the other end of the connecting rods is fixedly connected to the inner circumferential wall of the rinsing tank.

[0009] In a preferred embodiment of this utility model, a plurality of the aforementioned perforations are formed through the inner circumference of the rinsing frame, and the bottom of the rotating cylinder is rotatably connected to the bottom inner wall of the rinsing frame.

[0010] In a preferred embodiment of the present invention, a plurality of scrapers are fixedly connected to the outer circumferential wall of the rinsing frame, and the outer sides of the plurality of scrapers are tightly fitted to the inner circumferential wall of the rinsing frame.

[0011] In a preferred embodiment of this utility model, a plurality of the aforementioned grooves are formed through the inner circumference of the rotating cylinder, and the outer circumference of the baffle is fixedly connected to the outer circumference of the rinsing frame.

[0012] In a preferred embodiment of this utility model, the inner circumferential wall of the baffle is rotatably connected to the outer circumferential wall of the rotating cylinder.

[0013] In a preferred embodiment of the present invention, the drive assembly includes: a protective housing and a servo motor disposed within the protective housing.

[0014] In a preferred embodiment of this utility model, the protective shell is fixedly connected to the bottom of the rinsing frame, and the bottom of the servo motor is fixedly connected to the bottom inner wall of the protective shell.

[0015] In a preferred embodiment of this utility model, one end of the output shaft of the servo motor passes through the rinsing frame and is fixedly connected to the bottom of the rotating drum.

[0016] In a preferred embodiment of this utility model, a discharge hole is provided on the bottom inner wall of the rinsing tank.

[0017] In a preferred embodiment of this utility model, a plurality of support rods are fixedly connected to the bottom of the rinsing tank, and anti-slip pads are adhered to the bottom of each of the support rods.

[0018] This utility model solves the defects existing in the background technology, and has the following beneficial effects:

[0019] (1) This utility model provides a high-efficiency rinsing device for treating contaminated soil. By pouring contaminated soil and water into a rotating drum, the soil and water are initially mixed and filtered by the trough inside the rotating drum, and then flow into the rinsing frame and the rotating drum. Subsequently, the servo motor drives the rotating drum to rotate, which not only promotes the uniform dispersion of soil particles, but also the scraper fixed to the outer wall of the rotating drum continuously and effectively scrapes the soil, allowing it to flow out through several holes. This not only improves the rinsing efficiency, but also ensures that the soil particles can be more fully exposed in the rinsing liquid, thereby achieving deeper removal of pollutants.

[0020] (2) This utility model provides a high-efficiency rinsing device for treating contaminated soil. During the rotation of the rotating drum, soil particles enter the rinsing frame through the trough under the action of gravity and scrapers, and are evenly distributed through the holes. This design reduces the problems of soil accumulation and water waste that may exist in traditional rinsing methods. At the same time, the rinsing nozzles precisely spray the soil discharged through the holes, achieving targeted rinsing of contaminated soil, further saving water resources and improving the treatment effect.

[0021] (3) This utility model provides a high-efficiency leaching device for treating contaminated soil. Through the coordinated work of the scraper and the leaching nozzle, it achieves comprehensive and in-depth treatment of contaminated soil. The continuous scraping action of the scraper effectively avoids the agglomeration of soil particles during the leaching process, allowing the soil and the leaching liquid to come into fuller contact, thereby improving the removal rate of pollutants. At the same time, the entire leaching process is highly automated, reducing manual intervention and lowering the difficulty and labor intensity of operation. Attached Figure Description

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. These drawings are simplified schematic diagrams, which are only used to illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0029] like Figure 1 As shown, a high-efficiency rinsing device for treating contaminated soil includes: a rinsing tank 1, a rinsing mechanism 4 disposed inside the rinsing tank 1, and a plurality of rinsing nozzles 6 disposed on the inner circumference of the rinsing tank 1.

[0030] like Figures 2-3 As shown, the rinsing mechanism 4 includes: a rinsing frame 401, a rotating cylinder 404 disposed on the inner wall of the bottom of the rinsing frame 401, a plurality of drainage grooves 8 disposed on the inner circumference of the rotating cylinder 404, a plurality of scrapers 405 disposed on the outer circumference of the rinsing frame 401, a plurality of drainage holes 402 disposed on the inner circumference of the rinsing frame 401, a baffle 406 disposed between the inner circumference of the rinsing frame 401 and the outer circumference of the rotating cylinder 404, and a driving assembly disposed at the bottom of the rinsing frame 401.

[0031] The outer circumferential wall of the rinsing frame 401 is fixedly connected to the inner circumferential wall of the rinsing box 1. Several rinsing nozzles 6 are fixedly installed on the inner circumferential wall of the rinsing box 1, and the several rinsing nozzles 6 are distributed on the outside of the rinsing frame 401. Several connecting rods 7 are fixedly connected to the outer circumferential wall of the rinsing frame 401, and the other end of the several connecting rods 7 is fixedly connected to the inner circumferential wall of the rinsing box 1.

[0032] A plurality of perforations 402 are formed through the inner circumference of the rinsing frame 401. The bottom of the rotating cylinder 404 is rotatably connected to the bottom inner wall of the rinsing frame 401. A plurality of scrapers 405 are fixedly connected to the outer circumference of the rinsing frame 401. The outer sides of the scrapers 405 are tightly fitted to the inner circumference of the rinsing frame 401. A plurality of perforations 8 are formed through the inner circumference of the rotating cylinder 404. The outer circumference of the baffle 406 is fixedly connected to the outer circumference of the rinsing frame 401. The inner circumference of the baffle 406 is rotatably connected to the outer circumference of the rotating cylinder 404.

[0033] It should be noted that the rinsing mechanism 4 installed in the rinsing tank 1, especially the combination of the rotating cylinder 404 and the trough 8 in the rinsing frame 401, achieves thorough mixing of contaminated soil and water, and gradually introduces the soil into the rinsing frame 401 during rotation. This process not only promotes the uniform dispersion of soil particles but also significantly increases the contact area with the rinsing liquid, thereby greatly improving the rinsing efficiency. The rinsing nozzle 6 can perform targeted rinsing on the soil discharged through the drain hole 402, effectively removing contaminants from the soil and significantly improving the cleaning effect.

[0034] Driven by the rotation of the rotating cylinder 404, the scraper 405 continuously and effectively scrapes away the soil, effectively preventing soil clumping, ensuring uniform dispersion of soil particles, and further enhancing the rinsing effect.

[0035] In addition, the arrangement of the drain hole 402, the drain groove 8 and the scraper 405 enables the entire rinsing system to operate in an orderly and efficient manner, effectively reducing water waste and significantly improving resource utilization efficiency.

[0036] like Figures 1-4 As shown, the drive assembly includes: a protective shell 5, a servo motor 403 disposed inside the protective shell 5, the protective shell 5 being fixedly connected to the bottom of the washing frame 401, the bottom of the servo motor 403 being fixedly connected to the bottom inner wall of the protective shell 5, one end of the output shaft of the servo motor 403 passing through the washing frame 401 and being fixedly connected to the bottom of the rotating cylinder 404, a discharge hole 2 being provided on the bottom inner wall of the washing tank 1, and several support rods 3 being fixedly connected to the bottom of the washing tank 1, with anti-slip pads adhered to the bottom of each of the support rods 3.

[0037] It should be noted that the combination of the protective housing 5 and the servo motor 403—with the servo motor 403 installed inside the protective housing 5 and directly driving the rotating drum 404 through its output shaft—not only improves rinsing efficiency but also ensures stable power transmission. The protective housing 5 provides necessary protection for the servo motor 403, preventing external interference, reducing noise and vibration, and extending the lifespan of the servo motor 403. Simultaneously, the automated operation driven by the servo motor 403 significantly reduces manual labor intensity.

[0038] In addition, the discharge hole 2 at the bottom of the washing tank 1 is designed to facilitate the discharge of the treated soil, while the support rod 3 and its anti-slip pads ensure the stability of the entire device.

[0039] In use, an appropriate amount of contaminated soil is poured into the rotating drum 404 inside the washing tank 1, and an appropriate amount of clean water or washing liquid is added to ensure that the soil is fully soaked. The servo motor 403 is started to work, and its output shaft drives the rotating drum 404 to rotate inside the washing frame 401. As the rotating drum 404 rotates, the contaminated soil and water are fully mixed in the drum and gradually enter the washing frame 401 through the trough 8. During this process, the soil particles are evenly dispersed, increasing the contact area with the washing liquid. The scraper 405, driven by the rotating drum 404, continuously scrapes the soil to prevent soil clumping and ensure the even dispersion of soil particles.

[0040] Soil particles enter the outer area of ​​the rinsing frame 401 through the perforation 402. At this time, the rinsing nozzle 6 starts to work and sprays precisely onto the soil. The rinsing liquid comes into full contact with the soil and effectively removes pollutants from the soil. After thorough rinsing, the treated soil and waste liquid are discharged through the discharge hole 2 at the bottom of the rinsing tank 1. A collection container can be set up to receive the discharged soil for subsequent treatment or utilization.

[0041] Based on the preferred embodiments of this utility model described above, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
