Description

Technical Field

[0001] This invention belongs to the field of textile technology, specifically relating to an energy-saving and emission-reducing device for recycling and reusing purified water after liquid dyeing. Background Technology

[0002] Traditional liquid dyeing machines primarily use nozzles to spray dye liquor, transporting fabrics to the dyeing tank for immersion. After passing through a sorting mechanism at the end of the dyeing tank, the fabrics are arranged neatly and moved forward sequentially to the front of the tank. Then, a cloth-carrying wheel lifts the fabrics, changing their direction of travel, and they re-enter the nozzles in a reciprocating cycle. During operation, the equipment relies on the dye liquor for propulsion, resulting in significant water consumption during the dyeing process. Summary of the Invention

[0003] The main objective of this invention is to propose an energy-saving and emission-reducing device for recycling and reusing purified water after liquid flow dyeing. By sampling and analyzing the water quality of the rinsing water after liquid flow dyeing, and based on the analysis results of COD, SS, pH, temperature, etc. of the dyeing wastewater at each stage of liquid flow dyeing, the detergent water that meets the requirements for recycling and reuse can be recycled and reused. Compared with traditional liquid flow dyeing equipment, it can effectively save 30-40% of water, significantly reduce the cost of water, steam, and wastewater treatment in dyeing plants, and achieve the goal of protecting water resources and the environment due to the significant reduction in absolute sewage discharge.

[0004] To achieve the above objectives, this invention proposes an energy-saving and emission-reducing device for recycling and reusing purified water after liquid dyeing, comprising a heater, a pump body, a partition plate, a mixing tank, a guide pipe, a storage tank, and a reuse piping. The mixing tank is connected to the pump body via a pipe, the pump body is connected to the input end of the heater, the output end of the heater is connected to the guide pipe, and both ends of the guide pipe are connected to both ends of the mixing tank. The partition plate is disposed inside the heater, dividing the heater into two parts. The storage tank is disposed on one side of the mixing tank, and one end of the storage tank is connected to the reuse piping. The other end of the reuse piping is connected to the input end of the pump body.

[0005] Preferably, the energy-saving and emission-reduction device for recycling and reusing purified water after liquid dyeing further includes a return pipe, the two ends of which are respectively connected to a guide pipe and a heater.

[0008] Preferably, the energy-saving and emission-reduction device for recycling and reusing purified water after liquid dyeing also includes a line, which is slidably connected to the roller.

[0009] Preferably, the energy-saving and emission-reduction device for recycling and reusing purified water after liquid dyeing further includes a maintenance manhole and an overflow pipe. The maintenance manhole is located on the liquid storage tank, and one end of the overflow pipe is connected to the maintenance manhole.

[0010] Preferably, the energy-saving and emission-reduction device for recycling and reusing purified water after liquid dyeing further includes a level gauge and a thermometer, which are installed on the storage tank.

[0011] Preferably, the energy-saving and emission-reduction device for recycling and reusing purified water after liquid dyeing further includes a flow meter and an automatic valve, which are installed on the recycling pipeline.

[0012] Preferably, by providing an inspection port, operators can easily perform regular cleaning and rinsing to ensure the quality of the recycled water. By providing an overflow port, the safety of the water storage tank during the recycling process can be ensured, and safe use can be guaranteed when over-recycling occurs. By providing a level gauge, operators can easily observe the water level in the storage tank during use. By providing a thermometer, the temperature of the recycled water can be recorded and observed to prevent abnormal recycled water temperatures. By providing a flow meter, the volume of fresh water and recycled water can be recorded to facilitate the confirmation and recording of the recycling rate.

By providing the controller, the operation of the water recycling storage tank can be controlled in conjunction with the dyeing process of the liquid flow dyeing.

[0013] This invention adds a water storage tank.

The storage tank 5 is connected to one end of the reuse piping 51, and the other end of the reuse piping 51 is connected to the input end of the pump body 2.

[0025] This invention adds a water storage tank.

It also includes a level gauge 6 and a thermometer 8, which are installed on the liquid storage tank 5. Furthermore, it includes a flow meter 9 and an automatic valve 13, which are installed on the reuse piping 51.

[0028] By setting up inspection holes, operators can easily perform regular cleaning and rinsing to ensure the quality of the recycled water. By setting up liquid flow outlets, the safety of the water storage tank during the recycling process can be ensured, and safe use can be guaranteed when over-recycling occurs. By setting up level gauges, operators can easily observe the water level in the storage tank during use. By setting up thermometers, the temperature of the recycled water can be recorded and observed to prevent abnormal recycled water temperatures. By setting up flow meters, the volume of fresh water and recycled water can be recorded to facilitate the confirmation and recording of the recycling rate. By setting up automatic valves, the flow direction of dyeing water during the recycling / reuse process can be controlled to facilitate recycling and reuse. The controller is connected to the level gauge 6, thermometer 8 and flow meter 9 respectively. By setting up the controller, it can control the operation of the water recycling storage tank in conjunction with the dyeing process of liquid flow dyeing.
