Printing and dyeing machine capable of filtering printing and dyeing sewage

Abstract

The invention discloses a printing and dyeing machine capable of filtering printing and dyeing sewage, and relates to the technical field of printing and dyeing. The printing and dyeing machine comprises a printing and dyeing table; the printing and dyeing table is of a rectangular structure and the interior is hollow; the internal hollow structure of the printing and dyeing table penetrates through the right wall surface of the printing and dyeing table; a main body is arranged at the right side of the printing and dyeing table; and the main body is of a rectangular structure and the interiorof the main body is hollow. According to the printing and dyeing machine capable of filtering the printing and dyeing sewage provided by the invention, a drainage pipe is arranged, and the drainage pipe is a pipe of a wave-shaped structure; the interior of the drainage pipe is a pipe that fluctuates up and down from left to right; activated carbon plates are arranged inside the drainage pipe; theactivated carbon plates can filter and adsorb oily impurities in the printing and dyeing sewage, when the sewage in accelerated movement from a pressure tank to the interior of the drainage pipe doesnot move upwards from the an internal slope of the drainage pipe, fiber impurities and sand impurities in the sewage are blocked by the activated carbon plates; and when sewage liquid passes throughthe activated carbon plates, the oily impurities are filtered once by each activated carbon plate, so that the effect of multiple filtering of large particle impurities is achieved.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a printing and dyeing machine capable of filtering printing and dyeing sewage. Background technique [0002] Printing and dyeing, also known as dyeing and finishing, is a processing method and a general term for pretreatment, dyeing, printing, finishing, washing, etc. As early as the Neolithic Age six or seven thousand years ago, our ancestors were able to use Hematite powder dyes linen red. The primitive tribes living in the Nomuhong area of ​​the Qaidam Basin in Qinghai can dye wool into yellow, red, brown, blue and other colors, and weave woolen cloth with colored stripes. During the Zhou Dynasty, the dyeing technology continued to improve, and there were full-time officials in the palace handicraft workshops to "dye the grass" to manage the dyeing production, and the dyed colors continued to increase. By the Han Dynasty, the dyeing technology had reached a very hi...

Problems solved by technology

[0003] With the development of social technology, traditional printing and dyeing has gradually realized mechanical automation production, which has greatly improved the work efficiency of printing and dyeing, but the problem that comes with it is that modern After the printing and dyeing machine dyes the textile fabric, the printing and dyeing machine discharges a large amount of sewage. The printing and dyeing wastewater contains dyes, pastes, auxiliaries, oil agents, acids and bases, fiber impurities, sand substances, inorganic salts, etc., and these impurities contain sewage Direct discharge into the river water will cause great harm to the environment. Therefore, a printing and dyeing machine that can filter printing and dyeing sewage is invented.
