Textile production wastewater treatment flocculation and cutting device

Abstract

The invention relates to the technical field of textile wastewater treatment equipment, in particular to a textile production wastewater treatment flocculation and cutting device which structurally comprises a pipe body, a turbulent flow device and a flocculation and cutting device. The turbulent flow device is used for reducing the flow speed of large batting and long fibers of foreign matter, and the situation that the large batting and long fibers directly pass through filter holes under the impact of water flow can be avoided, the large batting and long fibers are hinged off through cooperation of the movable filter plate and the fixed filter plate, the problems that small batting and short fibers cannot pass through filter holes of the filter plates and the filter screen needs to be replaced when the filter screen is quickly scrapped due to the fact that the filter holes of the filter screen and the filter plate are blocked by fluff and fibers can be effectively solved, and the device has practical significance and popularization value and is expected to generate good economic benefits.

Description

technical field [0001] The invention relates to the technical field of textile wastewater treatment equipment, in particular to a flocculation and cutting device for textile production wastewater treatment. Background technique [0002] Textile wastewater refers to all kinds of wastewater generated in the textile production process, including printing and dyeing wastewater, chemical fiber textile wastewater and wool washing wastewater, including suspended solids, grease, debris, surfactants, dyes, fluff and Various impurities such as long fibers, the current treatment method for this type of wastewater is multi-stage classification and step-by-step treatment. In this process, filter screens and filter plates are used to gradually filter foreign matter; fluff or long fibers are impacted by wastewater The bottom will be compressed and deformed to make it pass through the filter holes that could not pass through originally. These uninterrupted large groups of fluff and long len...

[0002] Textile wastewater refers to all kinds of wastewater generated in the textile production process, including printing and dyeing wastewater, chemical fiber textile wastewater and wool washing wastewater, including suspended solids, grease, debris, surfactants, dyes, fluff and Various impurities such as long fibers, the current treatment method for this type of wastewater is multi-stage classification and step-by-step treatment. In this process, filter screens and filter plates are used to gradually filter foreign matter; fluff or long fibers are impacted by wastewater The bottom will be compressed and deformed to make it pass through the filter holes that could not pass through originally. These uninterrupted large groups of fluff and long lengths of fibers will stretch in the next section and block and entangle in large quantities, making the next The small-diameter filter holes in the working section are quickly clogged. Not only large pieces of foreign matter cannot pass through small pieces of fluff, but short fibers also cannot pass through. This is also the reason why textile wastewater treatment equipment needs to replace filter elements frequently. Some wastewater treatment equipment will The blade driven by the driving device is installed, but the effect is not ideal due to the large gap between the blades and the foreign matter making it easy for fluff and fibers to leave the gap

[0003] The prior art technology discloses a water pollution treatment device that automatically replaces the filter screen (application number 202010502032.7), which can realize the automatic replacement of the filter screen, but it does not fundamentally solve the problem that the filter screen is easy to tangle and clogged, making the filter screen The root cause of the failure of the filtering function, the symptoms are not the root cause
