Dye sludge dewatering device

Abstract

The invention discloses a dye sludge dewatering device which comprises a sludge tank and a dewatering tank, wherein a plurality of dewatering pipes are arranged in the dewatering tank; each dewatering pipe is provided with an inner pipe and an outer pipe; the inner pipe is arranged inside the outer pipe; the walls of the inner pipe and the outer pipe are provided with through holes; the inner pipe is connected with a first motor for controlling the inner pipe to rotate around the own central axis; the outer pipe is connected with a second motor for controlling the outer pipe to rotate around the own central axis; one end of the inner pipe is communicated with the sludge tank through a guide pipe, and the other end of the inner pipe is sealed; and the rotation directions of the inner pipe and the outer pipe are opposite. The dye sludge dewatering device has the advantages of saving water resources and shortening dye sludge drying time.

Description

technical field [0001] The invention relates to a dyed sludge dewatering device. Background technique [0002] Textile materials are treated with a dye bath to chemically or physically combine dyes with fibers, or to generate insoluble colored substances on fibers. Dyes should have certain properties such as resistance to washing, sunlight, and friction on textiles. This property is called color fastness. When the dye is dyed, the characteristic of the transfer of the dye from the dye solution to the fiber is called directness, and in dyeing thermodynamics, it is called dyeing affinity, or affinity for short. Under certain conditions, the affinity of dyes to fibers is determined by the properties of dyes and fibers. Various types of fibers have their own applicable dyes, which can be selected according to requirements. The categories of dyes commonly used for cellulose fibers are: direct dyes, sulfur dyes, vat dyes, temporarily soluble vat dyes, insoluble azo dyes and re...

AI Technical Summary

Problems solved by technology

The categories of dyes commonly used for cellulose fibers are: direct dyes, sulfur dyes, vat dyes, temporarily soluble vat dyes, insoluble azo dyes and reactive dyes. During the dyeing process, sludge will appear, and the sludge contains a lot of water. Currently , Generally, the sludge is dried directly without separating the water in the sludge, which wastes water resources; secondly, it increases the time for drying the sludge
