Description

Technical Field

[0001] The invention relates to the technical field of reactive dye wastewater treatment, in particular to reactive dye dyeing equipment for recycling dyeing wastewater. Background Art

[0002] Reactive dyes are also called reactive dyes. They contain chemically active groups in their molecules and can react with cotton, wool and other fibers in aqueous solution to form co-bonded dyes. They have high wash fastness. In addition, a large amount of hydrolyzed dyes are produced during the reactive dye dyeing process. The wastewater after reactive dye dyeing is usually discharged directly, causing pollution to the surrounding environment and wasting resources. Therefore, the wastewater needs to be collected and treated to avoid pollution to the surrounding environment. The treated wastewater can be used again. When treating reactive dye dyeing wastewater, corresponding wastewater recycling equipment is required.

[0003] Based on the above, the existing reactive dyeing equipment for recycling dyeing wastewater has the following shortcomings:

[0004] The dyeing wastewater generated after the reactive dye dyeing is completed usually needs to go through multiple steps of filtration to remove harmful substances in the dyeing wastewater, but the fading process is not completed, so that the dyeing wastewater still presents a light color. It cannot be reused and will be directly discharged, which will waste resources and pollute the environment. In addition, the treatment efficiency is low when the dyeing is recycled, which affects reproduction. Summary of the invention

[0005] The disclosed embodiment relates to an active dye dyeing device for recycling dyeing wastewater, which connects the front end of a liquid taking pipe to the middle of the rear bottom of a dyeing bin so that the dye has better circulation fluidity.

The dyeing pipe and the dyeing branch pipe connected by the dyeing pump cooperate so that the upper and lower sides of the fabric are sprayed and colored so as to better color the fabric passing through the dyeing bin, and the shunt pipe of the liquid taking pipe pumps the dye that needs to be replaced and faded to the dyeing wastewater treatment bin through the shunt solenoid valve pump, and injects hydrogen peroxide solution into the dye through the auxiliary liquid connector to oxidize the dye. The shunt pipe on the liquid taking pipe cooperates with the shunt solenoid valve pump to pump the dye to the dyeing wastewater treatment bin.

After the fading is completed, the winding winch is driven by the driving motor to rotate, the winding winch tightens the winding rope, and the sealing plate is opened, so that the faded solution flows into the bottom filter tank, passes through the filter screen plate of the bottom filter tank inserted in the bottom filter tank, and under the action of the reflux solenoid valve pump, the faded solution returns to the dyeing bin through the reflux pipe, completing the fading process of the dyeing wastewater and re-injecting it into the dyeing bin, so as to add dye again to form a new dyeing solution, and after filtering the impurities through the filter screen plate of the bottom filter tank, the purity of the solution can be guaranteed, and after the sealing plate is closed, the bottom filter tank can be drawn out from the bottom filter tank to clean the bottom filter tank.
