Abstract

A mine ecological restoration soil improvement device and its use method belong to the field of soil restoration devices, and can solve the problem that, due to the reasons of extremely poor soil matrix pollution in mines, low organic matter content, low clay content and poor texture, the current mine soil pollution restoration technology sprays or injects an improvement agent into the surface soil layer for restoration, but the improvement agent diffused by the penetration effect cannot fully combine with the soil particles, and the partial activation of heavy metal elements can cause harm. The steps are: S1: the motor is powered on to drive the paddle to rotate; S2: the soil is poured into the feed port, and the paddle separates the soil; S3: the water pump is powered on to spray the soil restoration agent on the soil; S4: the motor is powered on to drive the sieve plate to rotate, and the hardened soil is crushed.

Description

Technical Field

[0001] This invention belongs to the field of soil remediation devices, and in particular to a soil improvement device for mine ecological restoration and its usage method. Background Technology

[0002] Mineral resources are important natural resources and a crucial material foundation for social production and development. Modern society relies heavily on mineral resources for both production and daily life. However, the development of mineral resources can cause environmental problems in mines, severely impacting the normal lives of people living around mining areas and social stability, making mine environmental restoration and remediation extremely challenging. Due to the extremely poor soil matrix, low organic matter content, low clay content, and poor texture of contaminated mine soils, current remediation technologies often involve spraying or injecting soil conditioners onto the surface. However, these conditioners, which diffuse through infiltration, cannot fully bind with soil particles, potentially leading to the partial activation of heavy metals and causing harm.

[0029] A method for using a soil amendment device for mine ecological restoration, the method comprising the following steps:

[0030] S1: Power on motor 1-3 to drive dial 2-6 to rotate;

[0031] S2: Pour the soil into the feed inlet 2-2, and use the baffle plate 2-6 to separate the soil;

[0032] S3: Power on water pump 3-4-4 to spray the soil remediation agent onto the soil;

[0033] S4: Power on motor 2 3-7 to drive screen plate 3-9 to rotate and break up the compacted soil.

[0034] The working principle of this invention is:

[0035] This device is connected to an external power source. During use, motor 1-3 is powered on, driving the rotating roller 2-5 via belt 1-4. Soil is poured into the feed inlet 2-2 and enters the screening box 2-1. The rotation of roller 2-5 drives the deflector plate 2-6, causing the soil to rotate within the screening box 2-1. Centrifugal force separates the gangue from the soil. The soil is then driven through the screening mesh 2-3 and falls through the discharge outlet 2-4 via the deflector plate 2-6. After soil separation, the deflector plate 2-6 continues to move the gangue and pushes it into the crushing pipe 2-7. The crushed stone moves downwards along the crushing pipe 2-7, continuously impacting the protrusions 2-8, causing the soil adhering to the gangue to fall off and fall through the crushing pipe holes 2-9 into the collection chamber. Inside the collection hood 2-10, the gangue slides down the crushed stone pipe 2-7 into the crushed stone recovery chamber 1-1 for collection. The soil from the discharge port 2-4 and the collection hood 2-10 falls onto the umbrella-shaped hood 3-4-1. The motor 3-4-10 is energized to rotate the umbrella-shaped hood 3-4-1. The soil, subjected to centrifugal force, is thrown onto the inner wall of the collection hood 3-1 and slides down its side. Soil remediation agent is pre-filled into the liquid tank 3-4-2. The water pump 3-4-4 is energized to extract the soil remediation agent from the liquid tank 3-4-2 and send it into the cavity 3-4-5. The soil remediation agent is sprayed out through the conical hole 3-4-6. When the soil slides to the lower end of the collection hood 3-1... When the soil remediation agent is sprayed onto the soil, it ensures full contact with the soil. The motor (3-4-10) rotates, driving the spray box (3-4-3) to rotate. The rotation of the spray box (3-4-3) in turn drives the scraper (3-4-7) to rotate. The scraper (3-4-7) prevents soil adhering with the soil remediation agent from sticking to the lower inner wall of the collection hood (3-1). Rotating the screw (3-4-8) moves the sealing plug (3-4-9) up or down in the cavity (3-4-5), changing the number of conical holes (3-4-6) and thus adjusting the spray volume of the soil remediation agent. Moving the sealing plug (3-4-9) upwards reduces the number of conical holes (3-4-6) and decreases the spray volume; moving the sealing plug (3-4-9) upwards increases the number of conical holes (3-4-6) and increases the spray volume. The -4-6 setting increases the spray distance of the soil remediation agent, ensuring it reaches the slid soil and conserves the agent. The flow rate of pump 3-4-4 is greater than that of the conical orifice 3-4-6. After the soil is sprayed with the remediation agent, it falls onto the inclined plate 3-6 in the collection box 3-5. As the soil accumulates, it tends to compact when the remediation agent dries. Powering motor 3-7 causes the screen plate 3-9 to rotate via shaft 3-8, breaking up the compacted soil. The inclined plate 3-6 facilitates soil removal, which can be done through the collection box outlet 3-10. The feed pump allows for faster and more convenient soil removal.

[0036] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of the equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0037] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
