Segment-type pretreatment tube for dye used for printing and dyeing

Abstract

The invention discloses a segment-type pretreatment tube for dye used for printing and dyeing. The pretreatment tube comprises a water inlet pipe, a fiber intercepting pipe 1 is installed on one sideof the water inlet pipe, and the fiber intercepting pipe 1 comprises an upper pipe shell and a lower pipe shell. When wastewater is introduced into the segment-type pretreatment tube for the dye usedfor the printing and the dyeing provided by the invention, intercepting plates in the fiber intercepting pipe 1 are floated, arc-shaped ends of the intercepting plates block filament-like fibers, intercepting nets located on two sides of the fiber intercepting pipe 1 intercept filament-like fibers, so that the interception effect is greatly improved; when the wastewater is no longer introduced, the intercepting plates are turned over by a rotating shaft to be in an upright state due to downward gravity, so that falling of the filament-like fibers is avoided, and the filament-like fibers are conveniently taken out; and when the wastewater passes through a fiber intercepting pipe 2, a velvety fibrous material is intercepted by hook blocks, and when water pressure drops, the velvety fibrous material is hooked by curved tip hooks on cross hooks, so that separation is avoided

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 existing in the above-mentioned prior art, and provides a segmente...
