Description

Uninterrupted grouting secondary mixing drum and inter-pump slurry suction manifold arrangement system

Technical Field

The utility model belongs to the auxiliary facilities of grouting filling engineering such as colliery abscission layer, collecting space area relates to a secondary churn and pump inter-suction thick liquid manifold's arrangement system.

Background

In the grouting process of grouting filling (settlement reduction, waste removal and the like) projects such as coal mine separation layers, goafs and the like, continuous grouting is not needed under non-special conditions, the grouting continuity is ensured, and the grouting continuity is a decisive factor directly influencing the grouting project quality. When the slurry flows in a pipeline, because of low flow velocity, factors such as wall-hanging property of the slurry, flow velocity change at a corner of a manifold, residue carried by the slurry and the like, the inner diameter of the slurry supply manifold is gradually reduced after scaling on the inner wall of the manifold, and finally the slurry is not blocked; stirring is seriously influenced after scaling in the secondary stirring tank, so residue and internal scale in the secondary stirring tank and a grouting pump slurry supply manifold need to be cleaned at variable time. Grouting is interrupted during cleaning, and water is forced to be injected instead in order to avoid the blockage of the drill hole and a pipe manifold between the drill hole and a grouting pump. Grouting is interrupted, the grouting filling effect is influenced if the grouting is interrupted, and engineering failure is caused if the grouting is interrupted.

The existing secondary mixing drum, a grouting pump slurry supply manifold arrangement system, a manifold and all connections between the manifold and each node of the manifold are connected by flanges and screws. The disadvantages of this arrangement are:

1) When slurry hanging scaling and waste residues in a slurry supply manifold are cleaned, in order to avoid blockage of a drill hole and the manifold between the drill hole and a grouting pump, a water supply pipeline provides water source, grouting can be replaced only by adopting a water injection mode, grouting is interrupted, and grouting can be recovered until the slurry supply manifold is cleaned; grouting interruption seriously affects the grouting filling effect, and simultaneously, the difficulty of discharging useless injected water at a grouting position is invisibly increased.

2) The manifold has the function of communicating the stirring pool with the slurry inlet tank, and is repeatedly designed, so that the manifold has no function in practice.

3) All connections between the valve and the manifold and between the manifold and each node of the manifold are connected by adopting flange screws, and when slurry and waste residues are removed, the installation and the disassembly are time-consuming and labor-consuming.

4) When the stirring tank is cleaned, slurry is supplied from one stirring tank, and the slurry supply amount is severely limited by the inner diameter of the slurry supply manifold.
