Automatic cement slurry preparation device and control method thereof

Abstract

The invention discloses an automatic cement slurry preparation device and a control method thereof and belongs to the field of water conservancy and hydropower equipment. According to the automatic cement slurry preparation device, a diluting water measuring device and a cement dense slurry measuring device are each provided with a series of different heights of overflow pipes, and therefore the automatic cement slurry preparation device is suitable for preparing different concentrations of cement slurry. The control method provided by the invention comprises the steps of starting cement slurry preparation when detecting that the liquid level of the cement slurry in a stirring device is lower than a preset value; measuring a preset added amount of diluting water through the diluting watermeasuring device and charging the measured diluting water into the cement stirring device according to the set cement ratio; measuring the preset added amount of cement dense slurry through the cementdense slurry measuring device, charging the measured cement dense slurry into the cement stirring device, stirring the cement slurry for preset time to complete preparation, and discharging the cement slurry through a discharge valve of the stirring device; and conducting a next round of automatic material preparation when the liquid level in the stirring device is lower than the preset value. Through the automatic cement slurry preparation device and the control method thereof, automatic and continuous operation of cement preparation can be realized, and the slurry preparation speed and efficiency are improved on a construction site.

Description

technical field [0001] The invention belongs to the field of water conservancy and hydropower equipment, in particular to an automatic cement slurry mixing device and a control method thereof. Background technique [0002] In the construction of water conservancy and hydropower projects, it is necessary to design and prepare cement slurry with different water-cement ratios according to different operating conditions. Usually fixed water and ash are used to prepare cement thick slurry, and then according to different operation requirements, cement thick slurry is used to prepare the corresponding proportion of water to prepare the cement slurry required for construction. [0003] In order to ensure the continuity of the slurry mixing operation, the current engineering usually adopts the control method of flow meter and valve, calculates the passing flow through flow detection, controls the ratio of cement thick slurry and water, and prepares cement mixing slurry. In the actu...
