Papermaking pulp separating and recovering device with primary mixing function

Abstract

The invention relates to a papermaking pulp separating and recovering device with a primary mixing function. The papermaking pulp separating and recovering device comprises a first supporting frame and a first drainage pipeline. A first filtering box is embedded in the upper end of the first supporting frame. A motor is connected with the middle of the lower end of the first filtering box. A sewage discharge table is arranged at the upper end of the first filtering box. A rotating shaft is placed at the lower end in the first filtering box. The papermaking pulp separating and recovering devicehas the advantages that sewage is discharged into the first filtering box through the sewage discharge table instead of being discharged into the first filtering box through a water pipe in the past,sewage can flow at the upper end of the sewage discharge table for a certain period of time, the sewage flowing face is uneven so that sewage can be blocked to a certain degree, the time of sewage staying at the upper end is prolonged, sewage can make sufficient contact with air, aeration is better conducted on sewage, and a preparation is made in advance for later-period sewage precipitation andmicroorganism method treatment.

Description

technical field [0001] The invention relates to the technical field of pulp separation and recovery devices for papermaking, in particular to a pulp separation and recovery device for papermaking with a preliminary mixing function. Background technique [0002] With the increase of paper production and consumption, the water consumption and wastewater discharge of the paper industry have also increased. In the world, the water pollution control of the paper industry has become a focus of attention of the paper industry and the whole society, and it is also the key to the survival and development of the paper industry. The key point is that the paper industry is one of the industries with large investment, high energy consumption, and serious environmental pollution. Its pollution is characterized by large wastewater discharge, high chemical oxygen demand, and a lot of fiber suspended matter in wastewater, so it needs to be treated in the sewage , and recycle the pulp inside....

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a paper pulp separation and recovery device with a preliminary mixing function, to solve the problem that the existing paper pulp separation and recovery device proposed in the above-mentioned background technology does not discharge the waste water into the filter box. The initial filtration will cause larger debris and sawdust in the wastewater to enter the filter box, and when chemicals are put into the filter box, the wastewater will naturally settle, so that there are still debris and debris in the pulp. Deposited resin affects the secondary utilization rate of recycled pulp
