Novel printing roller technology

Abstract

The invention provides a novel printing roller technology. A novel printing roller comprises a first sedimentation tank, a partition dam, a second sedimentation tank, a first electric pump, pipelines,a filter tank, a third sedimentation tank, a second electric pump, a distiller, a cooling tank, a decomposition tank, and a clean water tank. The first sedimentation tank and the second sedimentationtank are taken as a whole body and the partition dam is arranged in the middle of the first sedimentation tank and the second sedimentation tank. The first electric pump is arranged on the right sideof the second sedimentation tank, the water inlet of the first electric pump is connected to the second sedimentation tank through a pipeline, and the water outlet of the first electric pump is connected to the filter tank in the right side of the first electric pump through a pipeline. The third sedimentation tank is arranged under the filter tank. The second electric pump is arranged on the right side of the third sedimentation tank, the water inlet of the second electric pump is connected to the third sedimentation tank through a pipeline, and the water outlet of the second electric pump is connected to the distiller in the right side of the second electric pump through a pipeline. By arranging the partition dam and filter tank, the problems of low processing efficiency and great influence on processing equipment of an environmentally friendly zero discharge processing system for processing sewage in a printing workshop are solved.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment, and in particular relates to a novel printing roller technology. Background technique [0002] The printing unit of the gravure printing machine includes a standard type and a top pressure cylinder type printing unit, the former consists of a printing plate cylinder and an impression cylinder. Among them, the printing plate cylinder is cylindrical, and the surface is plated with copper as the plate material, and then through engraving or photo-etching, concave graphics and texts are formed on the surface of the cylinder. The printing plate cylinder of the gravure printing machine is directly immersed in the ink tank, and the ink under high-speed operation quickly fills the printing plate cylinder, and then the ink on the blank part of the printing plate surface is scraped off by the scraper, leaving the graphic groove Part of the ink is transferred to paper or other substrates by rollin...
