Abstract

The invention discloses a papermaking wastewater filtering device which structurally comprises a filtering water tank, four filtering discs, a water pump, mud discharging electric valves, a control box, a driving device and a filtering disc rotating shaft, wherein the four filtering discs are sequentially arranged in the filtering water tank, the water pump is arranged on the surface of the left side of the filtering water tank, and the control box is electrically and tightly connected with the interior of the filtering water tank. The three groups of mud discharging electric valves are sequentially arranged below the water filtering tank, the driving device is arranged on the inner wall of the water filtering tank and is connected with the filtering disc through a chain, and the filteringdisc is provided with a filtering disc cleaning device. The filter material is prevented from being bonded, the device can be automatically retracted to the original position after being cleaned, theuse of the filter equipment is prevented from being influenced, meanwhile, the active cleaning agent is added, the cleaning speed is high, and the cleaning effect is good.

Description

technical field [0001] The invention relates to the field of wastewater treatment, in particular to a filter device for papermaking wastewater. Background technique [0002] Papermaking wastewater refers to the wastewater generated during the pulping and papermaking process. Including pulping and cooking wastewater, washing wastewater, bleaching wastewater and paper machine white water, etc. Papermaking wastewater has complex components and is a difficult industrial wastewater to treat. Therefore, the discharge of papermaking wastewater must be filtered. Because the wastewater contains complex and diverse substances, it is easy to stick. On filter discs, cleaning is difficult. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is realized through the following technical solutions: a papermaking wastewater filter device, the structure of which includes a filter water tank, a filter disc, a water pump, an electric mud disch...
