Description

A feeding device for cement density measurement

Technical Field

The utility model relates to an experiment auxiliary articles for use technical field especially relates to a feeding device for cement density measurement.

Background

The cement density measuring method generally comprises the steps of filling a certain weight of cement sample into a Li's bottle filled with a liquid medium under a constant temperature condition, obtaining the volume of cement through volume scales on the neck of the Li's bottle (the volume of the liquid medium discharged by the cement is the volume of the cement), and then calculating to obtain the cement density. In order to prevent the measured cement from generating hydration reaction, anhydrous kerosene is usually adopted as the liquid medium.

In the actual experiment process, an operator usually uses a small spoon to fill a cement sample into a Li's bottle a little by a little, so that the feeding efficiency is extremely low; if the cement amount added each time is too much or the cement adding speed is too fast, the liquid medium is easy to splash to the bottleneck and adhere to the cement, and the cement is easy to block the narrow neck part of the Li's bottle so as to interrupt the feeding, so that the experiment fails, the Li's bottle needs to be cleaned again when the experiment fails, and the experiment is carried out again after the drying, which is very inconvenient.

To this end, we propose a charging device for cement density determination.
