Description

Technical Field

[0001] The invention relates to the field of wastewater treatment, in particular to a printing and dyeing wastewater treatment and recycling device. Background Art

[0002] Printing and dyeing wastewater is generated during the printing and dyeing of cotton, linen, chemical fibers and their blended products, silk, wool dyeing and finishing, and silk factories. Specifically, each printing and dyeing process of 1 ton of textiles consumes about 100 to 200 tons of water, of which 80% to 90% is discharged as wastewater. Printing and dyeing wastewater has the characteristics of large water volume, high content of organic pollutants, high alkalinity, and large changes in water quality. The wastewater contains dyes, slurries, auxiliaries, oils, acids and alkalis, fiber impurities, sand substances, inorganic salts and other components. If discharged directly, it will cause environmental pollution and waste water resources. Therefore, it is very necessary to treat and recycle printing and dyeing wastewater.

[0003] At present, the treatment and reuse methods of printing and dyeing wastewater mainly include physical methods, chemical methods and biological methods. Among them, the most widely used physical method is the adsorption method. This method is to mix powder or particles of porous materials such as activated carbon and clay with wastewater, or let the wastewater pass through a filter bed composed of its granular materials, so that the pollutants in the wastewater are adsorbed on the surface of the porous material or filtered out. Due to its simple structure, it is widely used. However, in actual application, it is found that when the printing and dyeing wastewater is directly passed through a filter bed composed of its granular materials, there is a phenomenon that when the wastewater flow rate is too fast, part of the printing and dyeing wastewater is not completely in contact with the granular materials, resulting in the printing and dyeing wastewater being difficult to be effectively purified. For this reason, the present application proposes a printing and dyeing wastewater treatment and reuse device. Summary of the invention

[0004] Based on this, the purpose of the present invention is to provide a printing and dyeing wastewater treatment and reuse device to solve the technical problem that the existing printing and dyeing wastewater treatment method directly passes through a filter bed composed of its granular matter and has a poor purification treatment effect.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a printing and dyeing wastewater treatment and reuse device, comprising a treatment box, a stirring motor is installed on the top of the treatment box, a stirring paddle is connected to the driving shaft end of the stirring motor, a net cylinder is movably inserted into the top of the treatment box, the stirring paddle and the net cylinder are both extended into the treatment box, and there are multiple net cylinders, the multiple net cylinders are evenly distributed around the stirring paddle, and each of the net cylinders is filled with a porous substance with adsorption properties.

[0006] The present invention is further configured such that a purification bin and a sedimentation bin are provided in the processing box, the purification bin and the sedimentation bin are separated by a partition, an overflow groove is provided near the top of the partition, and the stirring paddle and the mesh cylinder are distributed in the purification bin.

[0007] The present invention is further configured such that a partition net is installed in the overflow trough, and a drainage pipe communicating with the purification chamber is provided at the bottom of the end wall of the treatment box.

[0009] The present invention is further configured such that a fixing ring is fixedly connected to the top of the net tube, a convex plate is arranged on the peripheral side of the top of the fixing ring, the convex plate abuts against the upper surface of the ring plate, a plurality of lifting rings are arranged on the upper surface of the convex plate, a top cover is also arranged on the top of the fixing ring, and a handle is arranged on the top cover.

[0010] The present invention is further configured such that a waste liquid delivery frame is movably embedded in the top of the sedimentation bin, and a filter screen is installed at the bottom of the waste liquid delivery frame.

[0011] The present invention is further configured such that two ends of the waste liquid delivery frame are provided with supporting plates abutting against the top of the side wall of the treatment box, and the filter is arranged obliquely.

[0012] In summary, the present invention mainly has the following beneficial effects:

[0013] The present invention arranges a purification bin and a sedimentation bin. The printing and dyeing wastewater is put into a waste liquid putting frame on the top of the purification bin. The filter screen can filter out fiber impurities and sand substances in the printing and dyeing wastewater. The printing and dyeing wastewater is filtered by the filter screen and falls into the sedimentation bin for sedimentation. When the liquid level of the printing and dyeing wastewater in the sedimentation bin is higher than the overflow chute, the upper clarified liquid of the printing and dyeing wastewater in the sedimentation bin is discharged into the purification bin. The porous substances with adsorption performance filled in a plurality of mesh cylinders distributed in the purification bin can be used to adsorb and filter out pollutants in the printing and dyeing wastewater, thereby achieving the purpose of multi-stage purification treatment of the printing and dyeing wastewater, so that the printing and dyeing wastewater can be recycled and reused, and the waste of water resources and environmental pollution are reduced.

[0014] By starting the stirring motor to drive the stirring paddle to rotate, the printing and dyeing wastewater in the purification chamber can be stirred. Combined with the evenly distributed structure of multiple mesh cylinders surrounding the stirring paddle, the printing and dyeing wastewater can be evenly contacted with the porous and adsorbent substances in the multiple mesh cylinders, thereby improving the purification treatment effect of the printing and dyeing wastewater.

By starting the stirring motor 2 to drive the stirring paddle 3 to rotate, the printing and dyeing wastewater can be stirred, and the structure of multiple net tubes 4 evenly distributed around the stirring paddle 3 allows the printing and dyeing wastewater to be evenly contacted with the porous substance with adsorption performance in the multiple net tubes 4, thereby improving the purification treatment effect of the printing and dyeing wastewater.

The stirring paddle 3 and the mesh tube 4 are both distributed in the purification chamber 6, and the sedimentation chamber 7 can be used for sedimentation of printing and dyeing wastewater. When the liquid level of the printing and dyeing wastewater in the sedimentation chamber 7 is higher than the overflow channel 9, the upper clarified liquid of the printing and dyeing wastewater in the sedimentation chamber 7 is discharged into the purification chamber 6, and is adsorbed and purified by the mesh tube 4, so as to achieve the purpose of multi-stage purification of the printing and dyeing wastewater. A partition 10 is installed in the overflow channel 9 for blocking impurities, and a drain pipe 11 is provided at the bottom of the end wall of the treatment box 1, which is connected to the purification chamber 6, and is used to discharge the purified printing and dyeing wastewater.

[0023] In this embodiment, a ring plate 5 is centrally arranged at the top of the purification chamber 6, and a plurality of support plates 13 are arranged around the ring plate 5. The support plates 13 are fixedly connected to the processing box 1 and the partition 8. The net cylinder 4 is vertically and movably plugged into the ring plate 5. A fixing ring 15 is fixed in the middle of the net cylinder 4.
