Description

Technical Field

[0001] This utility model relates to the field of soil ecological restoration technology, specifically to an organic pollutant desorption device for soil ecological restoration. Background Technology

[0002] Soil organic pollution refers to the phenomenon where toxic and harmful organic substances enter the soil, and their quantity and rate exceed the soil's purification capacity, disrupting the natural dynamic balance, causing dysfunction of the soil's natural functions, and reducing soil quality. This can seriously affect crop growth, development, yield, and quality. In order to remediate soils contaminated with organic matter and restore the soil ecology, it is necessary to use soil organic pollution desorption devices to heat and desorb organic pollutants inside the soil. This process utilizes high temperatures to thermally desorb and volatilize organic pollutants in the soil.

[0003] However, in actual operation, the desorption device for organic pollutants used in soil ecological restoration adopts a vertical structure. When the contaminated soil introduced into the device is heated and desorbed, the contaminated soil is squeezed and stacked inside the device, and the internal heating is generally slow and difficult to be uniform. The overall desorption process is time-consuming and inefficient, which is a shortcoming and not convenient for heating and desorbing organic matter from contaminated soil.

[0004] Now, a novel organic pollutant desorption device for soil ecological restoration is proposed to address the above-mentioned shortcomings. Utility Model Content

[0010] As a further technical solution of this utility model, the rear ends of the side plate and the conveyor belt respectively penetrate the interior of the rear end of the mounting groove.

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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 This utility model provides an embodiment: an organic pollutant desorption device for soil ecological restoration, including a base 1, supports 5 fixed on both sides of the top of the base 1, and a desorption rotating drum 6 movably connected between the supports 5, a connecting platform 2 fixed on the left side of the base 1, a drive motor 3 fixed on the left side of the top of the connecting platform 2, a reducer 4 fixed on the right side of the top of the connecting platform 2, a side cover 8 on the left side of the outside of the desorption rotating drum 6, an electric heating tube 9 installed on the inner side of the side cover 8, a side cover 13 on the right side of the outside of the desorption rotating drum 6, an electric heating tube 14 installed on the inner side of the side cover 13, a feed inlet 12 fixed at the top of the desorption rotating drum 6, a discharge outlet 15 fixed at the bottom of the desorption rotating drum 6, exhaust ports 26 fixed on the tops of both sides of the desorption rotating drum 6, and a control box installed at the front end of the connecting platform 2.

[0025] The two sides of the desorption drum 6 pass through the interior of the two sets of supports 5 respectively. The output shaft of the drive motor 3 is fixedly connected to the input shaft of the reducer 4. The output shaft of the reducer 4 is poweredly connected to the left side of the desorption drum 6 through a pulley structure.

[0026] Specifically, such as Figure 1 and Figure 2As shown, multiple sets of electric heating tubes 14 on both sides can heat the main body of the desorption drum 6 when energized. The contaminated soil is then introduced into the interior of the desorption drum 6 through the top feed port 12. After sealing the feed port 12 and the discharge port 15, the drive motor 3 can be controlled to start the desorption drum 6 to rotate slowly between the supports 5 using the reducer 4. The rotation of the desorption drum 6 can also cause the soil inside to turn up and down, so that the soil can be heated evenly and quickly for desorption treatment, improving the desorption treatment efficiency of the contaminated soil. After the soil desorption treatment is completed, the drive motor 3 is turned off and the bottom cover of the discharge port 15 is opened to export the remediated soil inside.

[0027] The base 1 has an internal mounting groove 16 at the top, and side plates 17 are fixed on both sides of the bottom of the mounting groove 16. A conveyor belt 18 is installed between the two sets of side plates 17, and the rear ends of the side plates 17 and the conveyor belt 18 pass through the interior of the rear end of the mounting groove 16.

[0028] Specifically, such as Figure 1 and Figure 3 As shown, when exporting the repaired soil, the conveyor belt 18 can be controlled to start rotating backward and transport the soil. After the repaired soil is exported from the discharge port 15 onto the conveyor belt 18, it can be quickly transported backward by the conveyor belt 18 for output.

[0029] A top frame 7 is fixed to the top of the support 5, and a feeding port 11 is provided through the top of ...

[0030] Specifically, such as Figure 1 and Figure 4 As shown, during the process of feeding contaminated soil, after opening the top feed port 12, the servo motor 19 can be controlled to start the drive screw 22 to rotate. While the screw 22 rotates, the feed port 11 can be driven to move down using the threaded sleeve 21. After aligning the bottom of the connecting pipe 10 with the inside of the feed port 12, the enlarged feed port 11 can then be used to quickly feed the inside of the device.

[0031] Working principle: When in use, the multiple sets of electric heating tubes 14 on both sides are energized to preheat the main body of the desorption drum 6. During the feeding of contaminated soil into the device, after opening the top feed port 12, the servo motor 19 can be controlled to start the drive screw 22 to rotate. As the screw 22 rotates, the threaded sleeve 21 can drive the feeding port 11 to move down. After aligning the bottom of the connecting pipe 10 with the inside of the feed port 12, the inside of the device can be quickly fed through the feeding port 11. The contaminated soil is then introduced into the inside of the desorption drum 6 through the top feed port 12. After closing the feed port 12 and the discharge port 15, the drive motor 3 can be controlled to start the desorption drum 6 to slowly rotate between the supports 5 using the reducer 4. As the desorption drum 6 rotates, it can also cause the soil inside to turn up and down, so that the soil can be heated evenly and quickly for desorption treatment.

[0032] After the soil desorption treatment is completed, the drive motor 3 is turned off and the bottom cover of the discharge port 15 is opened to export the repaired soil. At the same time, when exporting the repaired soil, the conveyor belt 18 can be controlled to start rotating and conveying backward. After the repaired soil is exported from the discharge port 15 to the conveyor belt 18, it can be quickly transported backward by the conveyor belt 18 for rapid output.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
