Textile printing and dyeing wastewater treatment device

Abstract

The invention discloses a textile printing and dyeing wastewater treatment device which comprises a device body, a fixing plate is fixedly installed at the bottom of the inner side of the device body, an electrical room is arranged at the bottom of the inner side of the device body through the fixing plate in a separated mode, and a yarn removing cylinder, a settling chamber and a water filtering chamber are fixedly installed at the upper end of the fixing plate. A water conveying pipe is inserted into the side wall of the device body, the water conveying pipe is inserted into the yarn removing cylinder, and a yarn removing mechanism is arranged in the yarn removing cylinder. The yarn removing mechanism is arranged in the yarn removing cylinder, a driving mechanism in the yarn removing mechanism is used for driving a rotating shaft to rotate, the rotating shaft drives a first mesh cylinder to rotate, the first mesh cylinder drives a second mesh cylinder to rotate, and while the second mesh cylinder rotates, a yarn winding needle in the second mesh cylinder winds silk threads in waste water on the side wall of the first mesh cylinder; and silk threads in the yarn removing cylinder can be collected, and the situation that large-area blockage is formed in the later filtering process, and waste water filtering is affected is avoided.

Description

technical field [0001] The invention relates to the field of wastewater purification, more specifically, to a wastewater treatment device for textile printing and dyeing. Background technique [0002] Printing and dyeing, also known as dyeing and finishing, is a processing method of textile fabrics, and is also a general term for pretreatment, dyeing, printing, finishing, washing, etc. The development of my country's printing and dyeing industry has been highly valued by the government and the textile industry. In recent years, the state has listed the technological transformation of the printing and dyeing industry as one of the key industries supported by the textile industry, and at the same time has given corresponding policy support in terms of technological development and scientific and technological research, so that my country's printing and dyeing industry has been greatly improved in terms of quality, variety, and efficiency. Great improvement, the overall competit...

[0003] However, a lot of waste water can be produced during printing and dyeing. In the prior art, these waste water are generally discharged directly. If the waste water is discharged directly, it will not only cause serious pollution to the environment, but also waste water resources extremely. In the prior art, it is used to Water purification has always been large-scale equipment, the cost is high, and there are impurities such as silk threads in the printing and dyeing water, which is extremely easy to block the equipment
