Description

A concrete flocculant test extraction device

technical field

The invention belongs to the technical field of concrete detection, and in particular relates to a concrete flocculant test extraction device.

Background technique

The Chinese patent CN201910556852.1 proposes a detection method of flocculant in sand and its detection device. In this method, since the flocculant is a hydrophilic substance, in the process of washing sand with wastewater, some flocculant must remain in the wastewater , and these flocculants will remain in the sand, and the addition of flocculants will affect the viscosity of water. Therefore, firstly prepare aqueous solutions of different concentrations of flocculants, and then measure the viscosity of the flocculant aqueous solution through the detection device, and then imitate the sand washing plant In the sand washing process, water and flocculant are mixed first to form a flocculant aqueous solution, and then added to the sand. The newly added flocculant is equivalent to the residual flocculant in the wastewater. The viscosity data is obtained by detecting the supernatant, and then The residual amount of flocculant in sand is calculated by fitting formula.

However, in the test of flocculant residue in sand, it is impossible to accurately weigh the required amount of sand, water, and flocculant, so that the weight ratio can meet the preparation requirements. The purpose of sand, resulting in less flocculant content in the supernatant after standing, affecting the accuracy of the test results, if the amount of water is too much, it will cause waste of water resources.
