Dye recycling circulation filtering device for textile dyeing machine

Abstract

The invention discloses a dye recycling circulation filtering device for a textile dyeing machine. The dye recycling circulation filtering device comprises a water pump, an oxidation pond, a filter pipe, a collection box and a permeate core column, wherein the water pump is connected with the oxidation pond on the right side through a pipeline; a water level measuring apparatus is fixed in the oxidation pond; a first electromagnetic valve is mounted at the bottom of the inner wall of the oxidation pond; the downside of the first electromagnetic valve is connected with the filter pipe below through a water pipe; a second electromagnetic valve is mounted on the inner wall of the bottom of the filter pipe; the second electromagnetic valve is connected with the collection box below through a water pipe; the two ends of the filter pipe are sealed by sealing covers. According to the dye recycling circulation filtering device disclosed by the invention, automatic operation is controlled by PLC; in the case of high water level in the oxidation pond, a yielding water self-priming pump runs, the water pump draws water outward, and the water level in the oxidation pond goes down; in the caseof low water level in the oxidation pond, the PLC controls the water pump to pump water into the oxidation pond; therefore, automatic operation is realized.

Description

technical field [0001] The invention relates to the technical field of textile equipment, in particular to a dye recovery circulation filter device for a textile dyeing machine. Background technique [0002] The production wastewater in the dye production industry has become one of the main pollution sources of water bodies, and because most dyes are toxic and refractory organic substances, their chemical stability is strong, and they have the "three effects" of carcinogenicity, teratogenicity, and mutagenicity. Therefore, in wastewater Even if the concentration of residual organic matter is very low, it will cause irreversible damage to the ecological environment of the water body. On the other hand, in order to facilitate the coloring of nylon and polyester with high alignment, less fiber voids, and strong hydrophobicity, nylon with better hydrophobic properties Disperse dyes are widely used in modern industry. The molecules of disperse dyes contain polar groups (such as h...
