A device for treating fiber impurities in printing and dyeing wastewater

Abstract

The invention relates to the technical field of printing and dyeing, and discloses a device for treating fiber impurities in printing and dyeing wastewater, including a box body, a rotating assembly and a filter assembly, a motor is fixedly installed on the top of the box body, and a second An electromagnetic block, the output shaft of the motor is fixedly installed on the top of the rotating assembly, the inner wall of the rotating assembly is fixedly connected with the outer wall of the filter assembly, the printing and dyeing wastewater treatment fiber impurity device, through the first electromagnetic block and the second electromagnetic block Used together, when the motor is working, the output shaft of the motor drives the vertical bar to rotate, and the vertical bar drives the spring to rotate. Since the end of the spring away from the vertical bar is provided with a second electromagnetic block, and the first electromagnetic block and the second electromagnetic block are located at the same If the center line is horizontal, during the rotation of the spring, when the spring rotates to a position close to the first electromagnetic block, the spring can be stretched, thereby increasing the scope of the filter assembly to grab fiber impurities in the wastewater and improving efficiency.

Description

technical field [0001] The invention relates to the technical field of printing and dyeing, in particular to a device for treating fiber impurities in printing and dyeing wastewater. Background technique [0002] Printing and dyeing wastewater is wastewater discharged from cotton, hemp, chemical fiber and its blended products, silk-based printing and dyeing, wool dyeing and finishing, and silk factories. The type of fiber and processing technology are different, and the water volume and quality of printing and dyeing wastewater are also different. 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 most difficult industrial wastewater to treat. The wastewater contains dyes, sizing agents, additives, oil agents, acids and bases, and fiber impurities. , sand substances, inorganic salts, etc. [0003] In the printing and dyeing process, several st...

AI Technical Summary

Problems solved by technology

[0003] In the printing and dyeing process, several steps will produce wastewater, and the amount of such wastewater is very large, and it is very troublesome to deal with, because if the fiber impurities in it are treated chemically, different printing and dyeing processes will make the fiber impurities in the wastewater Or the amount of other ingredients is different, so it is impossible to achieve targeted chemical treatment methods. Moreover, if you want to meet the recycling reference standard, the cost will be very high, so most of the printing and dyeing wastewater adopts physical methods, that is, filtration. However, in the process of filtration, most of the powder or particles of porous substances such as activated carbon and clay are mixed with wastewater, or the wastewater is passed through a filter bed composed of its particles, so that the pollutants in the wastewater are adsorbed on the porous substances. On the surface, it may be removed by filtration, so the cost is relatively low, but in the end it takes a lot of time to desludge, and the process of processing the filter is very troublesome, which delays the efficiency of wastewater treatment, so we have introduced a printing and dyeing wastewater The limit impurity device has the advantages of easy removal of fibrous impurities while having a good filtering effect
