Description

Technical Field

[0001] This utility model belongs to the technical field of organic polluted soil remediation equipment structure, and more specifically, it relates to an organic polluted soil remediation equipment. Background Technology

[0002] Microwave remediation is commonly used in soil remediation. However, due to the limited energy radiation range of microwaves, soil cannot directly absorb microwave energy beyond a certain boundary. Therefore, in large-scale soil remediation, some distant soil layers rely on heat conduction from nearby high-temperature soil layers for heating, significantly reducing the heating efficiency of distant or deep soils. This adsorption method not only results in low removal efficiency of organic pollutants from the soil but also increases energy consumption in the remediation process, prolongs remediation time, and greatly increases remediation costs. Utility Model Content

[0003] The purpose of this invention is to provide an organic polluted soil remediation device that improves the overall wave absorption performance of the soil by using a wave-absorbing agent, allowing the soil to be fully remediated during the movement process, thereby significantly improving the removal efficiency of organic pollutants.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: An organic polluted soil remediation device is provided, comprising a casing, a soil silo, a microwave absorber silo, a mixer, and a conveyor belt. A remediation box is connected to the casing at its top. The remediation box contains several magnetrons for heating the soil. The mixer is located above the casing and outside the remediation box. The soil silo and microwave absorber silo are both located above the mixer and are used to supply soil or microwave absorber to the mixer. A horizontally extending conveyor belt is provided inside the casing. The conveyor belt is used to receive soil from the mixer and move the soil to the bottom of the remediation box for soil remediation or to move the soil away from the remediation box.

[0007] In some embodiments, a leveling brush is connected to the lower baffle adjacent to the mixer, with a gap between the lower edge of the leveling brush and the conveyor belt, and the leveling brush is used to level the soil onto the conveyor belt.

[0008] In one possible implementation, the agitator has a feed inlet at the top, a stirring shaft is rotatably connected inside the agitator, and stirring blades are provided on the outer periphery of the stirring shaft.

[0009] In some embodiments, the top of the stirrer is provided with a downwardly extending rotary drive member connected to the stirring shaft.

The controller is used to send start and stop information to the discharge valve.

[0014] Compared with the prior art, the organic polluted soil remediation equipment provided in this application embodiment delivers soil from a soil hopper to a mixer and microwave absorber from a microwave absorber hopper to the mixer. The mixer effectively mixes the soil and microwave absorber, ensuring that the microwave absorber is evenly distributed in the soil to improve its adsorption performance.

In the description of this utility model, "a number" means two or more, unless otherwise explicitly specified.

[0023] Please refer to the following: Figures 1 to 3The organic polluted soil remediation equipment provided by this utility model will now be described. The organic polluted soil remediation equipment includes a casing 4, a soil silo 1, a microwave absorber silo 2, a mixer 3, and a conveyor belt 41. A remediation box 5 is provided above the casing 4 and communicates with it. The remediation box 5 contains several magnetrons 51 for heating the soil. The mixer 3 is located above the casing 4 and outside the remediation box 5. The soil silo 1 and the microwave absorber silo 2 are both located above the mixer 3 and are used to supply soil or microwave absorber to the mixer 3. The casing 4 contains a horizontally extending conveyor belt 41, which is used to receive the soil in the mixer 3 and move the soil to the bottom of the remediation box 5 for soil remediation or to move the soil away from the remediation box 5.

[0024] Compared with the prior art, the organic polluted soil remediation equipment provided in this embodiment has the following advantages: the soil hopper 1 supplies soil to the mixer 3, and the microwave absorber hopper 2 supplies microwave absorber to the mixer 3. The mixer 3 effectively mixes the soil and microwave absorber, so that the microwave absorber is evenly distributed in the soil to improve the soil's adsorption performance. After the soil and microwave absorber are mixed, they fall onto the conveyor belt 41 below and are transported by the conveyor belt 41 to the bottom of the remediation box 5. The magnetron 51 emits microwaves to heat and remediate the soil, ensuring the quality of soil remediation, improving the removal efficiency of organic matter in the soil, and meeting the soil remediation requirements.

[0025] In this embodiment, the magnetron 51 can be a high-frequency magnetron 51 or a low-frequency magnetron 51, or a combination of both. It can heat and repair the soil using microwaves of different frequencies, making it convenient to select different types of magnetrons 51 according to the soil type, which helps to improve the soil repair efficiency and ensure the soil repair quality.

[0026] The side wall of the casing 4 near the outlet end of the conveyor belt 41 is provided with a discharge port 42. The discharge port 42 is used to connect with the subsequent conveying components so that the repaired soil can be smoothly transported to the required position.

[0027] Specifically, commonly used microwave absorbing agents include the following types: resistive microwave absorbing agents, represented by carbon black and graphite, which absorb microwaves through their high resistivity; magnetic loss microwave absorbing agents, represented by ferrite, which absorb microwaves by utilizing the energy loss during the magnetization and demagnetization processes of magnetic materials; nano-absorbing agents, which enhance microwave absorption efficiency through their unique nanostructure; and polymer microwave absorbing agents, which convert microwave energy into heat or other forms of energy through the interactions between polymer molecules, thus achieving microwave absorption. Mixing microwave absorbing agents into soil can improve its microwave absorption performance, achieving more efficient microwave absorption and contributing to improved soil remediation efficiency.

[0028] In one possible implementation, the aforementioned feature repair box 5 can be adopted as follows: Figures 1 to 3 The structure shown is provided. Please refer to it as well. Figures 1 to 3 The magnetron 51 is mounted on the inside of the repair box 5 via the support frame 52. The magnetron 51 is arranged in several rows along the width direction of the conveyor belt 41, with adjacent rows of magnetron 51 staggered.

[0029] In this embodiment, the bottom of the repair box 5 has a lower opening communicating with the casing 4. When the soil carried by the conveyor belt 41 passes under the repair box 5, the magnetron 51 can act on the soil to achieve soil heating and repair. The support frame 52 is installed inside the upper part of the repair box 5 to reliably support the magnetron 51 and ensure the reliability of the magnetron 51 installation. Achieving soil heating and repair helps to improve repair efficiency.

[0030] Specifically, there are multiple rows of magnetrons 51 inside the repair box 5, with adjacent magnetrons 51 arranged alternately to make the arrangement of magnetrons 51 relatively uniform, thereby improving the uniformity of microwave heating of the soil below by the magnetrons 51.

[0031] In some embodiments, the feature repair box 5 described above can be adopted as follows: Figures 1 to 3 The structure shown is provided. Please refer to it as well. Figures 1 to 3 The lower edge of the remediation box 5 is connected to a downwardly extending lower baffle 6. The lower baffle 6 is set perpendicular to the direction of the conveyor belt 41. There are two lower baffles 6, which are located on both sides of the remediation box 5. The lower baffles 6 can block the area below the remediation box 5, so that the soil can be effectively remediated in the area between the two lower baffles 6.

[0032] Furthermore, the two lower baffles 6 are respectively set to opposite sides via extension plates 62, which facilitates expanding the space in which the soil can be acted upon by microwaves, so that the soil can be fully repaired and the repair quality can be improved.

[0033] In some embodiments, the feature repair box 5 described above can be adopted as follows: Figures 1 to 3 The structure shown is provided. Please refer to it as well. Figures 1 to 3 A leveling brush 61 is connected to the lower baffle 6 adjacent to the mixer 3. There is a gap between the lower edge of the leveling brush 61 and the conveyor belt 41. The leveling brush 61 is used to level the soil onto the conveyor belt 41.

[0034] In this embodiment, by setting a leveling brush 61 at the lower edge of the lower baffle 6 connected to the mixer 3, the soil on the conveyor belt 41 that is about to enter the area below the repair box 5 can be effectively leveled, avoiding local accumulation of soil on the surface of the conveyor belt 41, so that the soil can be spread evenly on the conveyor belt 41, improving the uniformity of soil repair on the conveyor belt 41 by the upper magnetron 51, which facilitates improved repair efficiency and ensures repair quality.

[0035] In one possible implementation, the aforementioned stirrer 3 can be employed as follows: Figures 1 to 2 The structure shown is provided. Please refer to it as well. Figures 1 to 2 The top of the agitator 3 is provided with a feed inlet 31, and a stirring shaft 32 is rotatably connected inside the agitator 3. Stirring blades 33 are provided on the outer periphery of the stirring shaft 32.

[0036] In this embodiment, the top of the agitator 3 is provided with a feed inlet 31, which can receive the soil in the soil silo 1 and the microwave absorber in the microwave absorber silo 2. The soil and microwave absorber are stirred and mixed by the stirring blades 33 on the outer periphery of the stirring shaft 32, so that the microwave absorber can be evenly distributed in the soil. The oxidation catalytic function of the microwave absorber is used to further degrade the organic matter in the soil, providing favorable support for the removal of pollutants.

[0037] In some embodiments, the aforementioned stirrer 3 can be employed as follows: Figures 1 to 2 The structure shown is provided. Please refer to it as well. Figures 1 to 2 The top of the stirrer 3 is provided with a downward extending rotary drive 34 connected to the stirring shaft 32. The rotary drive 34 is used to drive the stirring shaft 32 to rotate. The stirring blades 33 are arranged in several groups along the axial direction of the stirring shaft 32. Each group of stirring blades 33 includes several stirring blades 33 arranged circumferentially along the stirring shaft 32.

[0038] In this embodiment, the mixing is driven by a rotary drive 34. The rotary drive 34 can be a motor or a hydraulic motor, or it can be driven by other power components to rotate the mixing shaft 32. In turn, the circumferential rotation of the mixing blades 33 disturbs the soil and the absorbent, thereby achieving the effect of mixing the soil and the absorbent.

[0039] Specifically, multiple sets of stirring blades 33 are spaced apart along the axial direction of the stirring shaft 32, which can mix soil and microwave absorber at different heights. In addition, each set of stirring blades also includes multiple circumferentially spaced stirring blades 33, which can effectively mix soil and microwave absorber at different positions in the circumferential direction at the same height, ensuring the uniform distribution of microwave absorber in the soil.

[0040] In some embodiments, the aforementioned characteristic soil silo 1 and wave-absorbing agent silo 2 can be adopted as follows: Figures 1 to 2 The structure shown is provided. Please refer to it as well. Figures 1 to 2 The soil silo 1 and the microwave absorber silo 2 are each equipped with a feeding track 7 at their lower openings, which is connected to the feed inlet 31. The feeding track 7 gradually narrows from top to bottom. The feeding track 7 extends from the lower opening of the soil silo 1 or the microwave absorber silo 2 into the feed inlet 31, which can smoothly guide the soil and microwave absorber into the mixer 3, avoid material jamming or spillage, and ensure that the mixer 3 effectively mixes the soil and microwave absorber.

[0041] Please refer to one possible implementation as well. Figure 1 The top of the repair box 5 is connected to an exhaust gas treatment box 8, which is used to receive and treat the exhaust gas discharged from the repair box 5. For the exhaust gas generated during the repair process, the exhaust gas treatment box 8 can be used to treat the gas before it is discharged, avoiding environmental pollution caused by the direct discharge of harmful exhaust gas.

[0042] The exhaust gas treatment box 8 can use UV photo-oxidation equipment, which is used to remove odorous gases and volatile organic compounds (VOCs). It can effectively decompose polluting gases into harmless substances such as carbon dioxide and water vapor, and has a better removal effect.

[0043] In one possible implementation, the organic contaminated soil remediation equipment also includes a controller and a temperature sensor 53 and a control panel 9, which are electrically connected to the controller. The control panel 9 is located on the side of the remediation chamber 5 and has a display screen 91 and operation buttons 92. The temperature sensor 53 is located inside the remediation chamber 5 and is used to detect the temperature information inside the remediation chamber 5 and send the temperature information to the controller.

[0044] The repair chamber 5 is also equipped with a temperature sensor 53 electrically connected to the controller. The temperature sensor 53 is used to detect the temperature information inside the repair chamber 5 and send the temperature information to the controller. The temperature sensor 53 can detect the temperature inside the repair chamber 5 in real time, which facilitates the transmission of temperature information to the controller. The controller can display the corresponding temperature information on the display screen 91, making it convenient for the operator to obtain relevant parameters.

[0045] In some embodiments, please refer to the following: Figures 1 to 3 The soil silo 1 and the wave absorber silo 2 are respectively equipped with a meter and a discharge valve 11. The meter is electrically connected to the controller and is used to feed back metering parameters to the controller. The controller is used to send start and stop information to the discharge valve 11.

[0046] In this embodiment, by pre-setting parameters for the soil and the microwave absorber within the controller, a metering device accurately measures the falling soil or microwave absorber and transmits their respective weight parameters to the controller. The controller receives these weight parameters and determines whether the feeding amount meets the requirements based on the pre-set parameters. If the requirements are met, the controller sends a stop message to the discharge valve 11, thereby timely closing the soil hopper 1 or the microwave absorber hopper 2. Specifically, an impact-type solid flow meter can be used to meet the weighing requirements of the soil and the microwave absorber above.

[0047] Based on this, the bottom of the agitator 3 is equipped with a discharge valve 35 electrically connected to the controller. The controller can control the opening and closing of the discharge valve 35 of the agitator 3 to achieve automatic control of the equipment. During use, the above equipment can be operated manually or automatically to meet different usage requirements.

[0048] The aforementioned organic polluted soil remediation equipment utilizes a soil hopper 1 to supply soil to a mixer 3, and simultaneously utilizes a microwave absorber hopper 2 to supply microwave absorber to the mixer 3. The mixer 3 effectively mixes the soil and microwave absorber, ensuring that the microwave absorber is evenly distributed in the soil to improve its adsorption properties. After the soil and microwave absorber are thoroughly mixed, they fall onto a conveyor belt 41 below and are transported by the conveyor belt 41 to the bottom of the remediation tank 5. Microwaves are emitted by a magnetron 51 to heat and remediate the soil, ensuring the quality of soil remediation, improving the removal efficiency of organic matter in the soil, and meeting the soil remediation requirements.

[0049] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
