Description

Technical Field

[0001] This utility model relates to the field of ecological environment construction and engineering technology, and in particular to a turbidity filtration device after the existing drainage culvert of a tailings dam is sealed. Background Technology

[0002] Currently, in the production of mining enterprises, as tailings sand is piled up and consolidated in large quantities, the load itself increases, which can easily cause damage or collapse of the existing drainage system below. In the strength test of the tailings dam drainage system, it was found that once the strength of the existing drainage culvert is reduced, far below the design requirements, or even some have cracks, and cannot meet the requirements for continued safe use of the tailings dam, the drainage culvert must be sealed and a new drainage system must be rebuilt.

[0003] Regarding the aforementioned related technologies, the inventor believes that the following defects exist:

[0004] 1. Existing drainage culverts are often sealed with concrete. Due to the characteristics of the concrete setting process and the factors of creep in the later stage, many existing drainage culverts have cracks between them and the sealing body. At the same time, since the original drainage well windows were not sealed during ore discharge, tailings sand in the reservoir was discharged out of the reservoir with the water flow through the water pipe, which easily caused the overflow of turbid water and caused pollution to the river. Utility Model Content

[0005] To address the technical problems mentioned above, this utility model provides a tailings dam drainage culvert sealing and turbidity filtration device.

[0006] This utility model is achieved by the following technical solution: a turbidity filtration device after sealing the existing drainage culvert of a tailings dam, comprising: a sealing body;

[0007] Two existing drainage culvert walls are respectively installed on the top and bottom of the sealing body;

[0008] A water guide pipe is installed between the bottom of the sealing body and the corresponding existing drainage culvert wall.

[0009] The bottom inner wall of the corresponding existing drainage culvert is roughened and leveled by mortar.

[0010] The mortar is equipped with a filtration mechanism, which includes a frame cage, a first filter bag, and a second filter bag. The first filter bag is composed of a wire mesh, a non-woven geotextile, and coarse gravel. The frame cage is lined with a layer of wire mesh, the wire mesh is lined with a layer of non-woven geotextile, and the non-woven geotextile is filled with coarse gravel.

[0011] The above technical solutions can form a filtration system that can capture larger particles, silt and other impurities, thus solving the problem of turbidity caused by the blockage of existing drainage pipes in tailings ponds and its impact on the natural environment.

[0012] As a further improvement to the above solution, the cage is composed of two half-frames, and two mounting blocks are slidably installed on the two half-frames. A storage sleeve is provided between the two mounting blocks, and the storage sleeve is located behind the first filter pack.

[0013] As a further improvement to the above solution, both ends of the storage sleeve are rotatably mounted with internally threaded sleeves, and each of the two internally threaded sleeves is threaded with a threaded rod. The ends of the two threaded rods that are close to each other extend into the storage sleeve and are slidably connected to the storage sleeve.

[0014] As a further improvement to the above scheme, the ends of the two threaded rods that are far apart from each other are rotatably connected to the outer walls of the two half-frames that are close to each other, and the two mounting blocks and the two half-frames are respectively connected and fixed by multiple fastening bolts.

[0015] The above technical solution allows for adjustment of the frame size as needed during the initial construction and installation, thereby facilitating the cutting of wire mesh and improving its adaptability.

[0016] As a further improvement to the above solution, a second filter bag is provided between the first filter bag and the receiving sleeve. The second filter bag is composed of a second layer of wire mesh, a second layer of non-woven geotextile, and quartz sand. The frame cage is lined with a second layer of wire mesh, the wire mesh is lined with a second layer of non-woven geotextile, and the non-woven geotextile is filled with quartz sand.

[0017] The above technical solution can further filter out medium-sized solid particles. The sand layer, through its small pores, can intercept medium-sized particles in the water, thus solving the problem of turbidity caused by the blockage of the existing drainage pipes of the tailings dam and its impact on the natural environment.

[0018] As a further improvement to the above solution, the filtration mechanism is located on the side of the sealing body near the outer edge of the sealing body, and the sealing body is provided with slits.

[0019] As a further improvement to the above scheme, the wire diameter of the first wire mesh is 0.457mm and the aperture is 1.13mm. Both the first wire mesh and the second wire mesh are stainless steel wire mesh.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0021] This utility model has a simple structure and can be equipped with a filtration system behind the sealing body to filter the water flowing out of the sealing body, thereby meeting environmental protection emission requirements. Attached Figure Description
