Impregnation and filtration device for fountain solution wastewater of offset press for printing

Abstract

The invention discloses an immersion and filtration device for fountain solution wastewater of an offset press for printing, the immersion and filtration device comprises a base, wherein the base is provided with an immersion tank, the interior of the immersion tank is of a cavity structure, the top of the immersion tank is of an open structure, a filter bin is arranged in the immersion tank, anda sealing cover is arranged on the top of the filter bin; a plurality of limiting plates are arranged at the position of the inner bottom of the immersion tank, a limiting cavity is arranged between the limiting plates, and the bottom of the limiting cavity is wider than the bottom of the filter bin; hydraulic cylinders are arranged on both sides of the immersion tank, piston rods are arranged atthe upper parts of the hydraulic cylinders, a lifting frame is arranged between the top ends of the piston rods, a lifting rod is arranged in the middle of the lifting frame, buckling frames are arranged at the lower ends of the lifting rods, clamping plates are arranged on both sides of the buckling frame, buckling plates are arranged at the lower parts of the clamping plates, the filter bin is arranged between the buckling frames, and the buckling plates are arranged on the bottom surface of the filter bin. According to the invention, a filtered fountain solution enters the filter bin, and the fountain solution is purified through the filter bin, thus greatly improving the efficiency of filtering and purifying the fountain solution.

Description

technical field [0001] The invention relates to a filter device, in particular to a filter device for impregnating the fountain solution wastewater of an offset printing machine for printing. Background technique [0002] Fountain solution is an indispensable chemical additive in the printing process of color printing machines. It forms a uniform water film on the blank part of the printing plate to resist the infiltration of ink on the graphic and text to the blank part and prevent dirty plates. Fountain solution is also called wetting solution, sink solution, and bucket solution. The fountain solution contains a wetting agent that changes the surface tension of the printing plate surface, its pH buffer system provides a constant and stable pH, and is suitable for all types of water, and its anti-corrosion ingredients help protect your machine. It is a highly concentrated product and needs to be diluted before use. When using dampening additives, there is another problem ...
