Dyeing equipment and method allowing dye liquor to flow inwards and outwards at the same time

Abstract

The invention relates to dyeing equipment and method allowing dye liquor to flow inwards and outwards at the same time. In the dyeing equipment, an end socket is welded to the lower end of a cylinder body to form an airtight container, and the air container is supported and fixed through a supporting frame; a cheese creel is placed in the cylinder body and comprises a disc body and yarn rods, the disc body is hollow inside, and a plurality of yarn rods are evenly installed on the disc body; the yarn rods are hollow inside, an opening in the lower end of each yarn rod is communicated with an inner cavity of the disc body, and a plurality of small holes are formed in the wall of each yarn rod. The dyeing equipment is characterized in that the inner cavity of the disc body is divided into at least three mutually independent creel chambers through partition boards, a water access port is formed in the bottom of each creel chamber, the water access port of at least one creel chamber is connected with a water drainage port of a water pump through a periodical water flow reversing mechanism, and the water access ports of other creel chambers are connected with a water return port of the water pump through periodical water flow reversing mechanisms. According to the dyeing equipment, dye liquor conversion frequency is improved, effective circulation time is prolonged, and cost is saved.

Description

technical field

[0001] The invention relates to cheese dyeing technology, in particular to a dyeing device and a dyeing method in which dye liquor flows in and out simultaneously. Background technique

[0002] As a traditional mechanical equipment, cheese dyeing equipment has an irreplaceable position in the dyeing industry. However, the existing cheese dyeing equipment generally suffers from high pollution and high energy consumption, and the consumption of water, steam and electricity remains high. It is listed as a key environmental protection monitoring industry by the state, which brings heavy economic and psychological pressure to enterprises.

[0003] At present, cheese dyeing equipment on the market generally adopts the dyeing method that the dye liquor flows out or inward at the same time, and the dye passes through the yarn driven by the dye liquor water flow, so as to achieve the purpose of making the dye attach to the yarn to achieve yarn dyeing . However, due ...
