A segmented dye pretreatment tube for printing and dyeing

Abstract

The invention discloses a segmented dye pretreatment pipe for printing and dyeing, which includes a water inlet pipe, a fiber retention pipe 1 is installed on one side of the water inlet pipe, and the fiber retention pipe 1 includes an upper pipe shell and a lower pipe shell , when the segmented dye pretreatment pipe for printing and dyeing is passed into waste water, the retaining plate in the fiber retaining pipe 1 will float, and the arc-shaped end of the retaining plate will block the filamentous fibers, and the retaining nets on both sides will It will also intercept filamentary fibers, greatly improving the interception effect, and when no more waste water is passed through, the interception plate will turn over through the rotating shaft, and due to gravity, it will be in an upright state downwards, avoiding the shaking of filamentous fibers, greatly improving It is convenient to take out the filamentary fiber. When the waste water passes through the fiber retaining pipe 2, the velvet-like fiber material will be intercepted by the hook block, and when the water pressure drops, the velvet-like fiber material will be blocked by the curved point on the cross hook. Hook to hook and avoid disengagement.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing wastewater treatment, in particular to a segmented dye pretreatment pipe for printing and dyeing. Background technique [0002] During the printing and dyeing process, dyes will produce wastewater, and the general pretreatment is to remove the suspended solids and pumice residues in the wastewater to meet the discharge or reuse standards, and then carry out advanced treatment, but the current dyes used in printing and dyeing are segmented There are still some deficiencies in the use of the traditional pretreatment tube. At present, the segmented dye pretreatment tubes used for printing and dyeing cannot perform segmental treatment on filamentous and velvet fiber materials, which will affect the subsequent advanced treatment. Contents of the invention [0003] The present invention mainly solves the technical problems in the above-mentioned prior art, and provides a segmented dye pre...
