Abstract

The invention discloses a pulp-water separation device for papermaking wastewater, which belongs to the technical field of papermaking wastewater and comprises a liquid holding tank, a flocculation tank and a separation device. The liquid passage pipe in the flocculation tank. The flocculation tank is provided with a liquid passage pipe that overlaps with the separation device. The separation device includes a sedimentation tank, a separation component and a collection component. The separation component is installed on the top of the sedimentation tank and the separation component One end of one end extends to the top of the collection assembly, and the liquid storage tank is provided with a defoamer assembly and a partition assembly, the partition assembly is installed in the liquid storage tank, and the defoamer assembly is slidably matched with the top of the liquid storage tank. The present invention separates the water filter layer from the sedimentation tank through two stretching parts, and drives the pull wheel to rotate through the pulling motor so that the pulling rope pulls the sliding plate to move on the positioning plate, and the sliding plate drives the water filter layer to move into the collection box and passes through several A blowing nozzle blows the pulp fibers on the water filter layer into the collection box.

Description

technical field [0001] The invention relates to the technical field of papermaking wastewater, in particular to a pulp-water separation device for papermaking wastewater. Background technique [0002] At present, the water consumption of the papermaking industry is relatively large, generally 60-120 tons of water per ton of paper, and the wastewater concentration is high. There are many fine fibers in the papermaking wastewater, and the liquid volume accounts for about 5% of the treated water, and most of them are in the semi-suspended state. If the papermaking wastewater directly enters the regulating tank of the conventional treatment system and then settles, the sediment will decompose and stink, resulting in difficult wastewater treatment, complicated treatment process and high cost. [0003] Citing Patent No. CN102094345 A The invention relates to a slurry-water separation and recovery device before papermaking wastewater treatment. The recovery device of the inventio...
