Solid-liquid separation system for aluminum paste production and application method thereof

Abstract

The invention discloses a solid-liquid separation system for aluminum paste production and an application method thereof. The solid-liquid separation system comprises an aluminum paste dispersing machine, a material delivery pump, a filter press, an oil storage tank, a coalescing separator and oil-gas separators, and all the devices are communicated through pipelines and valves. The aluminum paste dispersing machine, the material delivery pump and the filter press are sequentially communicated, and the oil storage tank, the coalescing separator and the oil-gas separators are connected in parallel behind the filter press to form two independent branches. Filter liquor collected in the material filter-pressing process of the filter press enters the oil storage tank through the corresponding pipeline and corresponding valve, the subterranean flow technology is adopted in the filter-pressing operation, and therefore solvent oil does not volatilize in the whole filter-pressing process. In the process of blowing filter cake in the filter press dry through compressed air, the solvent oil in airflow is separated and recovered by the coalescing separator and the oil-gas separators, solid-liquid separation operation on aluminum paste and the solvent soil in the aluminum paste production process can be finished well, unorganized emission of VOCs during the solid-liquid separation operation can be avoided well, and the solid-liquid separation system has the advantages of saving energy and being environmentally friendly.

Description

technical field [0001] The invention relates to an aluminum-silver paste production system in the fine inorganic chemical industry, in particular to a solid-liquid separation system for aluminum-silver paste production and an application method thereof. Background technique [0002] Aluminum silver paste is an important metal effect pigment, which is produced with pure aluminum metal and has many characteristics of aluminum metal itself. Aluminum silver paste is a mixture of flaky aluminum particles with pigment properties and a solvent coated with a fatty acid film on the surface. Because of its superior corrosion resistance and decorative properties, it is widely used. The production method of aluminum silver paste is to mix aluminum powder with organic solvent, lubricant, etc. according to a certain ratio, and then place it in a ball mill for grinding. Afterwards, it is screened and solid-liquid separated to make a filter cake, and then kneaded and surface-treated to bec...
