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
The present invention relates to the plain boiled water stream waste removal equipment that a kind of paper machine system wet end is deviate from, especially relate to a kind of white wate tray blowdown apparatus efficiently.
Background technology
For saving water resource, the plain boiled water that paper machine system wet end is deviate from flows through back flow water pump, is back to use web part of paper machine again through fan pump, and reciprocation cycle so uses, and improves access times, reduces water resource waste.But in long-time repeatedly circulation; also can with serving bad result; such as can produce the impurity such as rotten slurry, grieshoch, resin; these impurity can pollute slurry, pollute the net blanket of paper machine wet end; the impact of quality aspect is caused, so white wate tray needs regularly online or shutdown blowdown to paper.
At present, general white wate tray blowdown is mainly realized by the sewage draining exit of bottom, and sewage draining exit is in concave design, makes heavy seeds be deposited on this, reaches the object of discharging heavy slag.But because of the liquid level of white wate tray usually high at one meter more than; and the light impurity on plain boiled water top cannot gather bottom; so cannot effectively discharge; the particularly material that easily wadding is poly-such as rotten slurry, resin, talcum powder; once a large amount of wadding is poly-; certainly will pollute paper machine net blanket, need stop cleaning, cause production loss larger.
Summary of the invention
Object of the present invention is exactly provide a kind of transformation simple to overcome defect that above-mentioned prior art exists, regulates simple, does not waste plain boiled water, can improve the white wate tray blowdown apparatus of qualification rate and production efficiency.
Object of the present invention can be achieved through the following technical solutions: a kind of white wate tray blowdown apparatus efficiently, comprise web part of paper machine, back flow water pump, heavy slag blow-off pipe, heavy sizing pump, described web part of paper machine is communicated with back flow water pump, described heavy slag blow-off pipe, heavy sizing pump is separately positioned on bottom back flow water pump, it is characterized in that, also comprise adjustable baffle plate, blowoff basin under light slag blow-off pipe and machine, described adjustable baffle plate is arranged in back flow water pump, back flow water pump is divided into blowdown district and overflow area, described heavy slag blow-off pipe, heavy sizing pump is positioned at bottom blowdown district, under described machine, blowoff basin is connected to overflow area by pipeline, and light slag blow-off pipe is set on this pipeline.
Described adjustable baffle plate is happened frequently by multiple cuboid rod iron and is formed, and carrys out controllable register height by increasing or reduce rod iron.
The length of described cuboid rod iron is identical with back flow water pump inner length, and width is 5.5cm, is highly 5.5cm.
Described cuboid rod iron is equipped with corresponding connecting hole and connecting rod up and down, and is provided with sealing gasket between adjacent cuboid rod iron.
Be provided with adjustable baffle plate installing hole in described back flow water pump, adjustable baffle plate sealing is arranged in back flow water pump.
Described light slag blow-off pipe is provided with control valve.
Compared with prior art, blowdown mode of the present invention has the following advantages:
One, the light impurity in white wate tray effectively can be allowed to enter fan pump without circulation, overflow to white wate tray outside;
Two, effectively can discharge some light impurities in overflow plain boiled water, avoid the foreign material such as rotten slurry, resin, talcum powder to remain in the stability of influential system in plain boiled water too much;
Three, the liquid level of adjustable white wate tray, makes its level stability, and then makes constant part more stable;
Four, transformation is simple, regulates simple, does not waste plain boiled water;
Five, reduce the fluctuation of production process original paper quality, improve qualification rate and production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
