A high-efficiency white water tray sewage device

Abstract

The invention relates to an efficient drain unit for a white water tray. The efficient drain unit comprises a paper machine mesh portion, a white water tank, a heavy residue discharge pipe and a heavy slurry pump. The paper machine mesh portion is communicated with the white water tank. The heavy residue discharge pipe and the heavy slurry pump are both arranged at the bottom of the white water tank. The efficient drain unit further comprises an adjustable baffle, a light residue discharge pipe and a drain pool under a paper machine; the adjustable baffle is disposed in the white water tank and divides the same into a discharge area and an overflow area; the heavy residue discharge pipe and the heavy slurry pump are disposed at the bottom of the discharge area; the drain pool is connected to the overflow area through a pipeline; the pipeline is provided with the light residue discharge pipe. Compared with the prior art, the efficient drain unit has the advantages that modification is simple, adjusting is simple, no white water is wasted, qualification rate can be increased and productivity can be improved.

Description

technical field [0001] The invention relates to a white water flow sewage discharge device for the wire part of a paper machine system, in particular to a high-efficiency white water pan sewage discharge device. Background technique [0002] In order to save water resources, the white water from the wire part of the paper machine system flows through the white water tank, and is reused to the wire part of the paper machine through the flushing pump. Such reciprocating use can increase the number of times of use and reduce the waste of water resources. However, in the long-term multiple cycles, it will also bring some bad results, such as impurities such as sludge, ash layer, resin, etc., which will contaminate the pulp, pollute the net blanket in the wet part of the paper machine, and cause serious damage to the papermaking industry. Production has an impact on quality, so the white water tray needs to be discharged online or shut down regularly. [0003] At present, the se...

AI Technical Summary

Problems solved by technology

However, because the liquid level of the white water pan is usually more than one meter high, and the light impurities in the upper part of the white water cannot accumulate to the bottom, they cannot be effectively discharged, especially for substances that are easy to flocculate, such as sludge, resin, and talcum powder. Once a large amount of flocculation Polymerization will inevitably cause pollution to the paper machine net blanket, and it needs to be shut down for cleaning, resulting in a large loss of production
