A sediment thickener

Abstract

The invention relates to a water conservancy mechanical facility, and particularly discloses a sediment thickener. The sediment thickener comprises a platform, wherein a mortar cylinder is arranged on the platform; a cone frustum which is concentric with the mortar cylinder is arranged in the mortar cylinder; a water inlet pipeline and an overflow pipeline are arranged on the upper part of the mortar cylinder; the water inlet pipeline is arranged along the tangent line of the cone frustum; the overflow pipeline is positioned at the upper end of the cone frustum; two discharge pipelines which are arranged along the flow direction of water current are arranged at the cylinder bottom of the mortar cylinder; feeding tanks are arranged below the discharge pipelines. After the arrangement of the cone frustum, the water current moves circularly around the cone frustum after entering from the water inlet pipeline, sediments are deposited under the actions of the impact of subsequent water current and the gravity of the mortar and flow into the feeding tanks from the discharge pipelines, and residual water overflows from the overflow pipeline and flows back into the Yellow River in order that the concentration of the mortar entering the feeding tanks is increased, so that the concentration of mortar entering a sediment transport system is ensured, and the sediment transport efficiency is increased.

Description

(1) Technical field [0001] The invention relates to a water conservancy mechanical facility, in particular to a sediment thickener. (2) Background technology [0002] The area along the Yellow River in Shandong Province includes Heze City, Jining City, Tai'an City, Dezhou City, Jinan City and Zibo City. The underground coal resources in the region are abundant. In recent years, with the gradual increase of the proportion of the coal resource mining industry in the local national economy, while the coal resource mining industry has promoted the development of the local social economy, it has also brought many negative impacts, causing serious geological and ecological damage, some Rivers stopped flowing, roads, bridges and culverts broke and sank, and hydropower facilities were damaged. In the subsidence area of ​​coal mining, where water accumulates all the year round, the area of ​​cultivated land is reduced, grain production is reduced or completely eliminated, and agric...

Problems solved by technology

However, when using pipeline sand transportation technology for filling, because the pipeline distance is relatively long, if the sediment content in the slurry is too low, the transport medium is mainly water instead of sediment. Therefore, under the condition of the same power consumption, the sand transportation Low efficiency will inevitably increase the cost of sand transportation

Therefore, before the pipeline transports the sediment slurry, it is necessary to thicken the sediment content of the Yellow River water, that is, by increasing or increasing the sediment content in the transported slurry, the purpose of reducing the cost of sediment transportation is achieved, but There is currently no mechanical facility for this
