Concentration device for colloidal solution

Abstract

The invention relates to a concentration device for a colloidal solution. The device is characterized by comprising a total liquid inlet pipe, a total liquid outlet pipe and four filtering cylinders.A cabin wall is arranged in each filtering cylinder, each filtering cylinder is divided into a filtering cabin and a water-permeable cabin through the corresponding cabin wall, and each filtering cabin is provided with a liquid inlet pipe and a liquid outlet pipe; the liquid inlet pipes are connected with the total liquid inlet pipe, an electric colloid discharging valve is connected to each liquid outlet pipe, and multiple ultrafiltration core pipes are arranged in the filtering cabins; the two ends of each ultrafiltration core pipe penetrate through the cabin walls and enter the water-permeable cabins, and an electrical conductivity detector is arranged in each filtering cabin; each water-permeable cabin is provided with a purification liquid outlet. The concentration device for the colloidal solution has the advantages that the automation degree is high, by adopting multiple filtering cylinders, continuous filtering can be continuously conducted in turn, the obtained colloidal silica is large in particle and high in concentration, and the device has high social benefits and wide market prospects.

Description

technical field [0001] The invention relates to a colloid solution production device, in particular to a colloid solution concentration device. Background technique [0002] Colloidal solution refers to a solution formed by dispersing solid particle drugs or polymer compounds of a certain size in a solvent. Its particles are generally between 1 and 100 nanometers, most of the dispersion medium is water, and a few are non-aqueous solvents. Solid particles are dispersed in the solvent as multi-molecular aggregates (colloidal particles) to form a heterogeneous heterogeneous dispersion system (lyophobic glue). Polymer compounds are dispersed in the solvent in the form of single molecules to form a single-phase uniform dispersion system (lyophilic) glue). This type of solution has its unique properties, which are different from low molecular dispersions - true solutions (dispersed phase particles less than 1 nanometer), and coarse dispersions - suspensions (dispersed phase part...
