[0001] The invention relates to the technical field of wastewater treatment devices for curtain fabric production and dyeing, and in particular to a wastewater treatment device and a treatment method for curtain fabric production and dyeing. Background Art

[0002] With the development of textile printing and dyeing industry, the impact of curtain printing and dyeing wastewater on the environment is increasing, and the research and development results of the treatment of printing and dyeing industrial wastewater are constantly being transformed and applied. Textile printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. It is one of the difficult industrial wastewaters to treat. The wastewater contains dyes, slurries, additives, oils, acids and alkalis, fiber impurities, sand substances, inorganic salts, etc.

[0003] At present, the treatment steps for dyeing wastewater in the existing technology are filtration and bleaching. The wastewater is mostly composed of dyes and slurries. When the dyes and slurries are filtered, due to their own characteristics, they are easily adhered or attached to the surface of the filter. Long-term filtration will cause accumulation of the filter, thereby affecting the filtration effect.

[0004] Therefore, we provide a device and method for treating dyeing wastewater in curtain fabric production to solve the problem in the prior art that dyes and slurries are easily adhered or attached to the surface of the filter screen. Summary of the invention

A water outlet is provided in the middle of the bottom of the bleaching device, and the bleached water is discharged from the water outlet.

[0008] Preferably, a first filter is provided in the middle of the shaking plate, and the first filter is provided directly below the water inlet. The sewage entering from the water inlet can fall into the middle of the first filter, so that the first filter filters the sewage and leaves the residue and slurry in the sewage on the top of the first filter.

[0010] Preferably, two groups of supporting boxes are arranged on both sides of the filtering device. The supporting boxes are arranged at the bottom of the residue outlet, and a collecting box is placed in the supporting boxes. The residue and slurry produced on the shaking plate can flow from the residue outlet along the inclined surface of the shaking plate into the supporting boxes placed in the collecting box.

[0015] A treatment method for a curtain fabric production dyeing wastewater treatment device, comprising the following steps:

[0016] Step 1: Filtration. Sewage is poured into the filter device from the water inlet. At this time, the sewage begins to impact the first filter screen in the middle of the shaking plate. The connecting plate connected to the bottom of the shaking plate begins to squeeze the spring, so that the connecting plate drives the connecting plate to expand and contract in the telescopic groove, and the shaking plate begins to swing up and down to form a shake. The first filter screen begins to filter the sewage and leaves the residue and slurry in the sewage on the top of the first filter screen. The shaking of the first filter screen prevents the residue and slurry from sticking to the surface of the first filter screen. After that, the residue and slurry flow from the residue outlet along the inclination angle of the shaking plate into the collection box placed in the carrier box set at the bottom of the residue outlet of the filter device;

[0017] Step 2: Cleaning. By moving the push-pull rod, the push-pull rod starts to squeeze the limit block, so that the spring at the bottom of the limit block drives the limit block to shrink into the shrinkage groove, cancels the limit on the push-pull rod, and allows the push-pull rod to slide in the extension groove. When the push-pull rod is moved in the extension groove, the push-pull rod starts to drive the sliding plate to slide on the surface of the shaking plate, so that the brush at the bottom of the sliding plate starts to clean the surface of the first filter screen, and cleans the remaining stubborn residue and slurry, and sweeps the residue and slurry from the residue outlet along the inclined surface of the shaking plate into the collection box. The holding blocks on both sides of the bottom of the sliding plate are held in the sliding grooves opened on both sides of the guide rails set on both sides of the shaking plate.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The present invention proposes a device and method for treating wastewater from curtain fabric production and dyeing. Wastewater is poured into the filter device from a water inlet. At this time, the wastewater begins to impact the first filter screen in the middle of the shaking plate. The connecting plate connected to the bottom end of the shaking plate begins to squeeze the spring, so that the connecting plate drives the connecting plate to expand and contract in the expansion groove, so that the shaking plate begins to swing up and down to form a shake. The first filter screen begins to filter the wastewater, and the residue and slurry in the wastewater are left on the top of the first filter screen. The shaking of the first filter screen prevents the residue and slurry from sticking to the first filter screen. The residue and slurry flow along the tilt angle of the shaking plate from the residue outlet into the collecting box placed in the supporting box arranged at the bottom of the residue outlet of the filter device. At this time, the second filter screen at the bottom of the collecting box begins to filter the residue and slurry again to prevent the residue and slurry from being rich in too much water. The water at the drain flows to the middle of the supporting box through the tilted bottom surface, and then flows back to the filter device through the reflux pipe arranged in the middle of the supporting box. The filtered sewage finally falls into the bleaching device arranged at the bottom of the filter device, and is discharged from the water outlet after bleaching in the bleaching device.
