An assembled tailings water siphon return device

Abstract

The invention discloses an assembled tailing water siphon water return device. The assembled tailing water siphon water return device comprises a drainage well protection device and a siphon device fixed on the drainage well protection device, wherein the drainage well protection device comprises a central ring (5) and a steel framework (4), wherein the steel framework (4) is connected with the central ring (5) through a suspension cable; a float bowl (3) and a Hall anchor (10) are arranged at the bottom of the steel framework (4); the float bowl (3) is connected with the bottom of the steel framework (4); the Hall anchor (10) is connected with the float bowl (3). On one hand, tailing water return is performed by using a siphon principle. On the other hand, the influence of the siphon water return device on the flood prevention structure of a drainage well can be lowered to the maximum extent, and upper-layer clear water can be taken conveniently. The assembled tailing water siphon water return device has the advantages of convenience, energy saving and economical efficiency in construction use, and reliable and stable performance.

Description

technical field [0001] The invention relates to a tailings water return device, in particular to an assembled tailings water siphon return device. Background technique [0002] Tailings pool refers to the place where dams are built to intercept valley mouths or enclosures, and are used to stockpile metal or non-metal mines for ore sorting and then discharge tailings or other industrial waste. According to the tailings stockpiling method, it can be divided into dry stockpiling and wet stockpiling. In the past, wet stockpiling was the most used method. [0003] Tailings are one of the products of sorting operations in beneficiation. The part with the lowest content of useful target components is called tailings. Tailings are different from waste rocks. Waste rocks refer to the surrounding rocks and minerals that have been mined without ore. The general name of Jiashi. Tailings are the products after crushing and sorting. The particle size is generally finer. The tailings fro...

Problems solved by technology

[0007] Among them, the self-flow backwater method does not need to consume electric energy. The tailings water enters through the flood discharge system inlet and flows into the sewage treatment tank through the flood discharge system. There is no storage space for rainwater. After rainwater is mixed with tailings water, the flow rate is relatively large, which exceeds the treatment scale of the sewage treatment tank, and zero discharge of tailings water cannot be realized.

[0008] In the way of pumping back water, buoy pumps need to be installed in the tailings pond. By reducing the water level in the reservoir area below the dead water level, a certain storage space can be reserved for rainwater. When the water interception measures around the reservoir area are in place, It is easy to achieve zero discharge of tailings water, but pumping back water requires a lot of electricity, which is uneconomical

[0009] CN201794149U discloses a tailings water siphon return device, the tailings water siphon return device does not consider the impact of the siphon device on the flood control and structure of the tailings pond flood discharge system, especially in the operation process, adding a water inlet cover plate It is necessary to move the siphon many times, and the operation has certain difficulties, so that its application is limited to a certain extent.
