A printing and dyeing enterprise wastewater fishing mechanism

Abstract

The invention discloses a mechanism for fishing fur from waste water of printing and dyeing enterprises. The mechanism comprises a waste water discharge pond and a water wheel, wherein a separator is arranged in the middle of the waste water discharge pond and divides the waste water discharge pond into a quick passing area and a slow passing area, the quick passing area is communicated with a water inlet, the slow passing area is communicated with a water outlet, a through opening is formed between the separator and the waste water discharge pond, a filter net is movably arranged at the through opening, a chemical feed pipe is arranged at the quick passing area and is provided with 2-5 layers of support plates, ferrous sulfate and solid hydrochloric acid are arranged on each layer of support plate, the support plates are arranged at equal distance, a filter plate is arranged above the quick passing area, the water wheel is vertically arranged in the slow passing area and comprises a motor, a water wheel body and a wiper blade, and the wiper blade is arranged above the filter plate. The mechanism has a simple structure, as the longitudinal filter net interception and the transverse water returning arrangement are combined, the interception efficiency is high, cotton yarns, fibers and impurities in waste water can be fished in an all-dimensional manner, the labor intensity of workers and waste water treatment cost are lowered, resources are saved, and the environment is protected.

Description

technical field [0001] The invention belongs to the technical field of printing and dyeing equipment, and in particular relates to a waste water fishing mechanism for printing and dyeing enterprises. Background technique [0002] The production of printing and dyeing enterprises needs to consume a lot of water resources. According to the current normal industry production level in our country, the annual water consumption reaches tens of millions of tons. The wastewater discharged generally contains a large amount of cotton yarn, fibers and impurities. If it is not treated, It will cause serious pollution to the ecological environment. In order to prevent the deposition and blockage of the subsequent treatment unit, a hair removal machine is installed at the wastewater inlet to intercept fibers and impurities. However, the cost of purchasing the existing hair removal machine is high and the failure rate is high. The self-made hair removal device is not clean, and it needs to...

[0002] The production of printing and dyeing enterprises needs to consume a lot of water resources. According to the current normal industry production level in our country, the annual water consumption reaches tens of millions of tons. The wastewater discharged generally contains a large amount of cotton yarn, fibers and impurities. If it is not treated, It will cause serious pollution to the ecological environment. In order to prevent the deposition and blockage of the subsequent treatment unit, a hair removal machine is installed at the wastewater inlet to intercept fibers and impurities. However, the cost of purchasing the existing hair removal machine is high and the failure rate is high. The self-made hair removal device is not clean, and it needs to continue to filter in the subsequent process, which increases the difficulty of wastewater treatment
