Description

Technical Field

[0001] This utility model relates to the field of soil pollution treatment technology, and in particular to a remediation device for treating organically polluted soil. Background Technology

[0002] Soil is an integral part of the ecological environment system and a crucial and fundamental comprehensive natural resource for human survival and development. However, with the rapid development of my country's industrialization, unreasonable mining and smelting emissions, long-term irrigation with wastewater and application of sludge, atmospheric deposition caused by human activities, and the use of chemical fertilizers and pesticides have led to severe soil pollution in my country, posing a serious threat to the safety of the human living environment. How to protect my country's land, remediate soil pollution, establish a virtuous cycle ecosystem, and achieve a harmonious balance between economic, environmental, and social benefits has become an urgent and important issue that needs to be addressed.

[0003] During the soil remediation process, it needs to be stirred and mixed with chemicals. Stirring in the mixing device is difficult and often not mixed thoroughly, which has a significant impact on the quality of soil remediation. As a result, the stirring effect is not ideal, affecting the quality of the finished product. Moreover, when the mixed mud and water are discharged, a lot of mud and water will remain on the inner wall of the mixing tank and the mixing device, resulting in resource waste. Utility Model Content

This device includes a mixing drum, a cover, and a mixing device. The mixing frame of the mixing device rotates to break up the soil, and the cutting blades rotate to cut and disperse the soil clumps, ensuring thorough mixing of the soil and the chemical solution and improving the molding quality. Furthermore, by incorporating a lifting drive device and a scraping component, the lifting drive device lowers the scraping component during discharge. During this descent, the inner wall of the mixing drum and the outer wall of the mixing frame are scraped, resulting in clean discharge and reducing resource waste caused by residual mud and water.

The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0024] Reference Figure 1-4 This utility model provides a remediation device for treating organically contaminated soil, comprising: a mixing drum 1, a discharge pipe 101 connected to the bottom end of the mixing drum 1, a valve installed inside the discharge pipe 101, a feed pipe 3 connected to the side wall of the mixing drum 1, a cap 2 provided at the top end of the mixing drum 1, a through hole 201 provided at the top end of the cap 2, a mixing device 4 provided inside the mixing drum 1, a scraping component 7 slidably engaged with the through hole 201 provided around the side wall of the mixing device 4, a bracket 6 fixedly connected to the bottom end of the mixing drum 1, and a lifting drive device 5 provided on the bracket 6 for driving the scraping component 7 to rise and fall.

[0025] The stirring device 4 includes a motor 401 whose bottom end is fixedly connected to the top end of the cover 2. The output end of the motor 401 passes through the bottom end of the cover 2 and is fixedly connected to a rotating rod 402. A stirring frame 403 is fixedly connected to the side wall of the rotating rod 402. Several cutting blades 404 are vertically fixed inside the stirring frame 403.

[0026] The lifting drive device 5 includes a second motor 501. The upper part of the second motor 501 is fixedly connected to the upper bottom end of the bracket 6. The output end of the second motor 501 passes through the top end of the bracket 6 and is fixedly connected to a screw 502. A baffle 503 is fixedly connected to the top end of the screw 502.

[0027] The scraping assembly 7 includes a lifting connecting frame 701. The height of the lifting connecting frame 701 is not less than the height of the mixing drum 1. The outer wall of one side of the inner side of the lifting connecting frame 701 is slidably connected to the inner side of the through hole 201. A fixing ring 702 is fixedly connected to the bottom end of the inner side of the lifting connecting frame 701. The outer side wall of the fixing ring 702 is in contact with the inner side wall of the mixing drum 1. The outer side wall of the screw 502 is threadedly connected to the bottom end of the outer side of the lifting connecting frame 701. A rotating groove 7021 is opened on the inner side wall of the fixing ring 702. A scraper 703 is rotatably connected to the inner side wall of the rotating groove 7021. A through hole 7031 is opened through the middle of the scraper 703. The inner side wall of the through hole 7031 is in contact with the outer side wall of the mixing frame 403. With the mixing drum 1, cover 2, and mixing device 4 in place, soil and pesticide solution are fed into the mixing drum 1 through the feed pipe 3 during use. The motor 401 drives the rotating rod 402 to rotate, which in turn drives the mixing frame 403 to rotate, breaking up the soil. The cutting blade 404 rotates to cut and disperse hard soil clods, ensuring thorough mixing of the soil and pesticide solution and improving the molding quality.

The moving scraper 703 rotates within the rotating groove 7021. During discharge, the second motor 501 drives the screw 502 to rotate, which, in conjunction with the limiting action of the first through hole 201, causes the lifting connecting frame 701 to descend. During the descent, the fixing ring 702 scrapes the inner wall of the mixing drum 1, and the scraper 703 scrapes the outer wall of the mixing frame 403. As the finished product is pressed, it is discharged from the discharge pipe 101 until the fixing ring 702 contacts the bottom of the drum, thus completing the discharge. The discharge is clean, reducing resource waste caused by mud and water residue.

[0028] Working principle: During use, soil and liquid medicine are fed into the mixing drum 1 through the feed pipe 3. The motor 401 is started to drive the rotating rod 402 to rotate, which in turn drives the mixing frame 403 to rotate, breaking up the soil. The cutting blade 404 rotates to cut and disperse hard soil clods, ensuring that the soil and liquid medicine are fully mixed. While the mixing frame 403 rotates, the scraper 703 rotates in the rotating groove 7021 through the limiting hole 7031. When discharging, the valve is opened, and the motor 501 is started to drive the screw 502 to rotate. With the limiting hole 201, the lifting connecting frame 701 is lowered. During the descent, the fixing ring 702 scrapes the inner wall of the mixing drum 1, and the scraper 703 scrapes the outer wall of the mixing frame 403. As the finished product is pressed, it is discharged from the discharge pipe 101 until the fixing ring 702 contacts the bottom of the drum. The discharge is clean, reducing the waste of resources caused by mud and water residue.
