A primary treatment device for sewage in a printing and dyeing factory

Abstract

The invention relates to the field of industrial waste water treatment, specifically a device for preliminary treatment of sewage in printing and dyeing factories. A motor is fixedly installed on the upper end of the main body of the device, a nylon sleeve is fixedly installed on the lower end of the motor, and a single-rotation reciprocating lead screw is fixedly connected to the lower end of the nylon sleeve. The lower end of the single-rotation reciprocating lead screw is fixedly connected with a rotating rod, the rotating rod is fixedly connected with a rotating piece, and a through hole is opened on the rotating piece, and the lower end of the rotating piece is fixedly connected with a slanted piece, which is installed through the connection between the lower end of the motor and the connecting plate. The friction between the nylon sleeve and the rubber block on the connecting plate generates static electricity, so that the collected polyester fiber in the polyester fiber box will be attracted by the static electricity and will not be taken out again, and because the nylon sleeve is set in a wave-shaped upper, lower, and lower The static electricity generated by friction is more efficient, and at the same time, it will generate wind force, which cooperates with the equidistant serrated grooves on the rubber block, so that the heat generated by friction can be removed faster, and the service life of the equipment is improved.

Description

technical field [0001] The invention relates to the field of industrial wastewater treatment, in particular to a preliminary treatment device for sewage in printing and dyeing factories. Background technique [0002] Printing and dyeing wastewater is mainly the wastewater discharged from processing cotton, hemp, chemical fibers and their blended products, silk-based printing and dyeing, wool dyeing and finishing, and silk factories. The types of fibers and processing techniques 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. [0003] However, most of the existing printing and dyeing wastewater treatment is filter-type treatment. This treatment method makes the treatment of water-absorbing cotton wool and non-absorbent polyester fibers in printing and dyeing ...

AI Technical Summary

Problems solved by technology

[0003] However, the existing printing and dyeing wastewater treatment is mostly filter-type treatment. This treatment method makes the treatment of water-absorbing cotton wool and non-absorbent polyester fiber in the printing and dyeing wastewater more troublesome and easy to cause blockage, which makes the filter device frequently replaced, resulting in waste water treatment. The efficiency is reduced, and the filtered cotton wool is squeezed together with polyester fibers and other harmful substances and cannot be recycled and reused
