Abstract
Description
Technical Field
[0001] This utility model relates to the field of reclamation of soil contaminated with heavy metals, specifically an isolation layer for reclamation of soil contaminated with heavy metals. Background Technology
[0002] Reclamation of soil contaminated with heavy metals refers to the process of remediating and reusing soil contaminated with heavy metals. Isolation in reclamation of soil contaminated with heavy metals is a method to reduce the harm of heavy metals to the environment and human health by setting up an isolation layer on the contaminated soil. A common isolation layer for reclamation of soil contaminated with heavy metals includes materials such as quicklime, loess, fine sand and activated carbon. These materials are mixed in volume ratio and laid on the top of the soil contaminated with heavy metals. Existing reclamation methods for soil contaminated with heavy metals lack protection for the land, which brings certain adverse effects to people's use. Therefore, we propose an isolation layer for reclamation of soil contaminated with heavy metals. Utility Model Content

[0019] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0020] This embodiment is an isolation layer for reclamation of soil contaminated with heavy metals.
[0021] like Figure 1-4 As shown, the structure includes a pit 1, inside which is an isolation mechanism 2. The isolation mechanism 2 includes a base 3, a fixing frame 4, a threaded groove 5, an isolation cover 6, a top cover 7, insert plates 8, slots 9, a knob 10, a first single-groove pulley 11, a first belt 12, a second belt 13, a second single-groove pulley 14, a first rotating shaft 15, a second rotating shaft 16, a threaded rod 17, a groove 18, a cavity 19, and a double-groove pulley 20. The base 3 is located inside the pit 1. Four sets of insert plates 8 are located at the front and rear ends of the upper outer surface of the base 3, respectively. Two sets of fixing frames 4 are located at the middle of the upper outer surface of the base 3, respectively. The threaded groove 5 is opened on the upper outer surface of the fixing frame 4. The isolation cover 6 is located at the upper end of the base 3. Four sets of slots 9 are opened at the front and rear ends of the lower outer surface of the isolation cover 6, respectively. Two sets of grooves 18 are opened at the middle of the lower outer surface of the isolation cover 6, respectively.
[0022] The threaded rod 17 is located inside the groove 18, the cavity 19 is opened in the middle of the top cover 7, the knob 10 is located in the middle of the upper outer surface of the top cover 7, and the lower end of the knob 10 is provided with a rotating shaft. The double groove pulley 20 is located on the outer wall of the rotating shaft. The first belt 12 is located at the upper end of one side of the double groove pulley 20; the second belt 13 is located at the lower end of one side of the double groove pulley 20. The first single groove pulley 11 is located on one side of the first belt 12, and the second single groove pulley 14 is located on one side of the second belt 13. The first rotating shaft 15 is located in the middle of the first single groove pulley 11, and the second rotating shaft 16 is located in the middle of the second single groove pulley 14. The insert plate 8 and the slot 9 are inserted together, the fixing bracket 4 and the groove 18 are inserted together, and the threaded rod 17 is threadedly connected to the threaded groove 5.
