Low-bath-ratio dyeing machine

Abstract

The invention relates to a fabric dyeing machine, in particular to a low-bath-ratio dyeing machine comprising a cylinder block, a circulating pump, and a dye tank. A large nozzle, a guide tube and a lift wheel are disposed in the cylinder block. The bottom of the cylinder block is provided with a cavity right below the large nozzle. A guide wheel is disposed in the cylinder block. A shield is arranged between the guide wheel and the cavity. Covering fences are arranged on two sides of the shield. One end, facing to the cavity, of the shield is provided with arc transition. The bottom of the cavity is connected with a first dye pipe of the circulating pump. The circulating pump is provided with a second dye pipe connected with the large nozzle. The dye tank is provided with a delivery pipe matching with the cavity. A delivery pump is further disposed outside the cylinder block and provided with a third dye pipe connected to the bottom of the cavity. The shield is provided with a plurality of spray guns which penetrate the shield; the spray guns are connected with a fourth dye pipe through the deliver pump. Compared with the prior art, the low-bath-ratio dyeing machine has the advantages that less water is used, the bath ratio is lower, water resources are greatly saved, production cost is reduced, and the reduction of water consumption results in reduction of wastewater discharge.

Description

Technical field [0001] The invention belongs to a dyeing equipment, in particular to a dyeing machine. Background technique [0002] The dyeing machine has many uses. For example, it can be mainly used for dyeing, bleaching, scouring and washing of sweaters, acrylic and cotton sweaters, etc. It can also be used for bleaching and dyeing of finished products such as gloves, socks, and towels. A wide range of bleaching and dyeing equipment. The main working principle of the dyeing machine is to use the circulating pump to promote the dye liquor to circulate along the pipeline, heat up through the heat exchanger assembly, and raise the dye liquor temperature to 130℃-135℃, and then flow through the filter assembly to filter, flow to the nozzle assembly, the nozzle assembly The dye liquor is sprayed onto the fabric under pressure and pushes the fabric into the cloth guide tube. The dye liquor is driven by the pump through the cloth guide tube and the bottom groove, and then flows back...

AI Technical Summary

Problems solved by technology

In order to drive the fabric to circulate in the master vat, the fabric must be continuously impacted with the dye solution. Therefore, the bath ratio must be increased. However, the increase of the bath ratio will cause a long heating time and a long cooling time of the dye solution, which is very wasteful. Resources such as steam, water, and electricity

At the same time, too much water is consumed in the dyeing process, the energy consumption of wastewater treatment is too large, the utilization rate of dyestuff is low, the dyeing time is long, the production efficiency is low, and the production cost is high, which cannot meet the needs of energy saving, emission reduction, low-carbon environmental protection.
