Description

Technical Field

[0001] This utility model relates to the field of soil remediation technology, specifically to a mixing device for soil remediation. Background Technology

[0002] The most common remediation methods for heavy metal contaminated soil are in-situ remediation and ex-situ remediation, with ex-situ remediation being a more effective and thorough technique. Ex-situ soil remediation involves excavating or extracting contaminated soil from its original location and transporting it to another site for treatment. This process often requires excavating the contaminated soil and then thoroughly mixing it using specialized equipment to achieve soil sieving, pollutant separation, and mixing with chemical treatment agents.

[0003] Publication No. CN218485807U discloses a mixing device for soil remediation, including a base plate. Four first support columns are fixedly connected to the upper surface of the base plate. A mixing tank is fixedly connected to the upper surface of the base plate. A through hole is opened at the bottom of the mixing tank. A bearing is fixedly connected to the inner surface of the through hole. A rotating shaft is fixedly connected to the inner surface of the bearing. Several mixing rods are fixedly connected to the outer surface of the rotating shaft. A cover plate is fixedly connected to the upper surface of the mixing tank. The advantages of this invention are: by incorporating a suction hood, connecting pipe, fan, and gas treatment box, the gas generated during mixing can be discharged into the gas treatment box through the suction hood and connecting pipe under the action of the fan, purifying harmful gases before being discharged to the outside, effectively preventing the harmful gases generated during mixing from harming the surrounding environment and human health. However, the existing technology still has disadvantages:

[0004] Existing soil remediation mixing devices involve directly adding the soil to be remediated into the mixing tank for mixing with the chemicals. While this mixes the soil and chemicals, the soil often exhibits clumping characteristics during actual operation. Soil clumping refers to the clump-like structure formed by soil particles in their natural state due to physicochemical factors such as the adsorption of moisture and clay minerals. Clumped soil particles can create obstacles inside the mixing tank, making it difficult for the chemicals to contact the soil evenly. This uneven contact results in some loose soil receiving sufficient treatment, while clumped soil does not, thus affecting the uniformity and effectiveness of the soil remediation effect.

[0005] The technical problem to be solved by this utility model is to overcome the above-mentioned defects and provide a mixing device for soil remediation.

[0006] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a mixing device for soil remediation, comprising: a mixing tank;

[0012] The feed hole is located at the middle of the upper end of the crushing box;

[0013] The hopper is fixedly connected inside the feed hole.

[0014] As an improvement, the stirring assembly includes:

[0015] A stirring shaft is rotatably connected to both sides inside the mixing tank via bearings;

[0016] A stirring plate, wherein several stirring plates are fixedly connected to the outside of the stirring shaft, and the several stirring plates are distributed in a spiral pattern;

[0017] Drive box two, which are fixedly connected to the rear end of the stirring shaft, and two drive boxes two are respectively fixedly connected to the two sides of the middle of the rear end of the mixing tank;

[0018] The discharge port is located at the lower front part of the inner side of the mixing tank;

[0023] As an improvement, a cover plate is rotatably connected to the front of the upper end of the mixing tank.

[0024] The advantages of this invention compared to existing technologies are as follows: This invention improves the uniformity of mixing by installing a crushing component. In use, the soil to be mixed is first added to the mixing tank through the hopper. Driven by a drive box, the fixed shaft rotates, driving the support rod and causing the crushing plates to move in a circular motion inside the crushing tank. The cooperation between the crushing plates and the sieve plate effectively crushes clumps of soil, which then falls into the mixing tank through the sieve. Subsequently, driven by a drive box, the mixing shaft rotates, and the spirally distributed mixing plates thoroughly mix and transport the soil. When the reagent is added to the mixing tank, it mixes with the soil, ensuring uniform mixing. Finally, the uniformly mixed soil is discharged through the discharge port. This effectively improves the uniformity and effectiveness of soil remediation, ensuring efficient remediation work. Attached Figure Description
