Description

Technical Field

[0001] The utility model relates to the technical field of spraying and screening devices, in particular to a heavy metal soil spraying and screening device. Background Art

[0002] The heavy metal soil spray screening device is a device used to treat heavy metal contaminated soil. It is an important device for soil remediation. It mixes a specific elution liquid with the soil to effectively transfer the pollutants in the soil to the liquid phase. The eluted soil is then separated from the liquid, and the eluted liquid is subsequently treated to remove the pollutants in it and meet the discharge standard or reuse standard.

[0003] When the soil spraying and screening device is working, different soil feed speeds will have different effects on the elution and screening effects. When the feed speed is too fast, the contact time between the soil and the eluent is reduced, and many pollutants cannot be effectively removed, resulting in a decrease in the elution effect. When the feed speed is too slow, although the contact time between the soil and the eluent can be increased, it will lead to a decrease in the treatment efficiency of the elution device and increase the treatment cost. However, the soil spraying and screening devices currently on the market are often unable to adjust the soil feed speed, and are unable to adjust the appropriate feed speed according to the actual conditions of the soil. Therefore, there is an urgent need for a spraying and screening device that can adjust the soil feed speed. Utility Model Content

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5 A heavy metal soil spraying and screening device comprises a soil spraying and screening device body 1, an adjusting channel 2 is fixedly and vertically arranged upward on one side of the soil spraying and screening device body 1, and an upper hopper 3 is fixedly arranged on the top of the adjusting channel 2. An adjusting member 5 is fixedly arranged inside the adjusting channel 2, and an adjusting cavity 52 is opened inwardly on both sides of the adjusting member 5. A movable member 8 is movably arranged in the adjusting cavity 52, and an extension plate 9 is fixedly and vertically arranged downward on the bottom of the outer side of the movable member 8. The adjusting channel 2 is arranged at the feeding end of the soil spraying and screening device body 1.

[0021] A partition plate 51 is fixedly disposed in the middle of the adjusting member 5 , and the partition plate 51 separates the adjusting chambers 52 on both sides.

[0022] The two ends of both sides of the partition 51 are fixedly extended outwards with guide posts 7, the other ends of the guide posts 7 are fixedly connected to the inner wall of the adjustment channel 2, and the movable parts 8 are located on the guide posts 7 and move. Through the provision of the guide posts 7, the movable part 8 can be guided during its movement, thereby ensuring the smooth movement of the movable part 8.

[0023] The top of the adjusting member 5 is fixedly provided with an inclined top plate 6, which is inclined from the middle to both sides. By providing the inclined top plate 6, when the adjusting channel 2 is loaded with materials, the soil can slide off the inclined top plate 6. If the inclined top plate 6 is not provided, a large amount of soil will accumulate on the adjusting member 5, which can prevent soil accumulation.

[0024] Among them, scrapers 61 are fixedly arranged on both sides of the adjusting member 5 above the adjusting cavity 52, and the scrapers 61 are in contact with the movable member 8. Through the arrangement of the scrapers 61, when the movable member 8 is retracted into the adjusting cavity 52, the soil on the top of the movable member 8 can be scraped off, thereby preventing the soil from entering the adjusting cavity 52.

[0025] Among them, a plurality of support columns 4 are fixedly arranged in the adjustment channel 2, and the support columns 4 are all fixedly arranged below the adjustment member 5. A hydraulic rod assembly 41 is fixedly arranged on one side of the support column 4 facing the extension plate 9, and the top extension end of the hydraulic rod assembly 41 is connected to the extension plate 9. Through the arrangement of the hydraulic rod assembly 41, the extension plates 9 on both sides can be pushed, so that the position of the movable member 8 can be adjusted. Moreover, the hydraulic rod assembly 41 is arranged below the adjustment member 5, so that the influence of the soil on the hydraulic rod assembly 41 can be reduced. And it is worth noting that the specific structure and working mode of the hydraulic rod assembly 9 are both existing technologies currently disclosed on the market, which are common knowledge known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0026] In this embodiment, when the user needs to rinse the soil, the soil can be poured into the upper hopper 3, and then the soil passes through the adjustment channel 2 and enters the interior of the soil spraying and screening device body 1 for rinsing and screening. And by setting the adjustment member 5 in the adjustment channel 2, the speed at which the soil enters the soil spraying and screening device body 1 can be controlled and adjusted. And it is worth noting that the specific structure and working mode of the soil spraying and screening device body 1 are both existing technologies currently disclosed on the market, which are common knowledge known to those skilled in the art, and do not belong to the main technical problems to be solved in this technical solution, so they are not elaborated in this utility model.

[0027] Furthermore, when the user needs to adjust the feeding speed of the soil, the top extension end of the hydraulic rod assembly 41 can be extended, and the extension plates 9 on both sides can drive the movable part 8 to move outward, and the material feeding space in the adjustment channel 2 is reduced, thereby reducing the feeding speed. When the user needs to increase the material feeding speed, it is only necessary to control the top extension end of the hydraulic rod assembly 41 on both sides to be retracted, and the extension plates 9 on both sides can drive the movable part 8 to move into the adjustment cavity 52, thereby increasing the material feeding space in the adjustment channel 2, thereby increasing the feeding speed.

[0028] In the utility model, the elution and screening of heavy metal soil can be achieved through the soil spraying and screening device body 1. By setting the adjustment channel 2 and the adjustment member 5, the speed at which the soil enters the soil spraying and screening device body 1 can be adjusted, so that the user can adjust the appropriate feeding speed according to different soils to ensure the elution and screening effect of the soil spraying and screening device body 1.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
