A dye vat for continuous tie-dyeing with reactive dyes

Abstract

The invention provides a dye vat for continuous dyeing in reactive dye tie dyeing, and belongs to the technical field of dyeing. The dye vat solves the problem of low cleaning efficiency in the prior art. The dye vat for continuous dyeing in reactive dye tie dyeing comprises a cylindrical vat body. A circular guide rail is fixed to the end face of the open end of the vat body, a sliding block is arranged on the guide rail and can slide along the guide rail, the sliding block is provided with an extension part extending to the inner side of the vat body, a cleaning roller is connected to the extension part in a rotating mode and is vertically arranged, the circumferential surface of the cleaning roller is attached to the inner wall of the vat body, and a rotating motor driving the cleaning roller to rotate is arranged on the sliding block. The vat body is further connected with a treatment device for denitrification nitrogen removal, the treatment device for denitrification nitrogen removal comprises a denitrification nitrogen removal tank, and the interior of the denitrification nitrogen removal tank is partitioned into a reaction tank and a sedimentation tank. The dye vat has the advantages that the dye vat can be automatically cleaned, and dye liquor can be automatically treated.

Description

technical field [0001] The invention belongs to the technical field of dyeing, and relates to a dye vat for continuous dyeing of active dye tie dyeing. Background technique [0002] The dye vat is the main tool used for cloth dyeing. When dyeing, the dyeing solution is added to the dye vat, and then the cloth to be dyed is added to achieve dyeing. [0003] Tie-dyeing is a dyeing method in which the fabric is partially ligated during dyeing so that it cannot be colored. It is one of the traditional Chinese manual dyeing techniques. Reactive dyes are the main dyes in tie-dyeing. In order to improve the efficiency of tie-dyeing, continuous dyeing is generally used at present. In continuous dyeing, the concentration of dye in the dye liquor will decrease during the dyeing process, so it is necessary to add dye, but the dye will stick to the inner wall of the dye vat during the dyeing process, and the dye may be re-mixed into the dye liquor during the dye liquor flow Therefore, ...

[0003] Tie-dyeing is a dyeing method in which the fabric is partially ligated during dyeing so that it cannot be colored. It is one of the traditional Chinese manual dyeing techniques. Reactive dyes are the main dyes in tie-dyeing. In order to improve the efficiency of tie-dyeing, continuous dyeing is generally used at present. In continuous dyeing, the concentration of dye in the dye liquor will decrease during the dyeing process, so it is necessary to add dye, but the dye will stick to the inner wall of the dye vat during the dyeing process, and the dye may be re-mixed into the dye liquor during the dye liquor flow Therefore, in order to ensure the accuracy of the dye concentration in the dye solution, it is necessary to clean the dye on the inner wall of the dye vat before adding the dye. Cleaning, the cleaning efficiency is low by this method, and the labor cost is high; the sewage generated during the dyeing process needs to be treated before being discharged. The traditional sewage treatment is only a simple treatment of the primary sewage, and there is no secondary advanced sewage treatment device
