Abstract
Preceding stock tank online concentration control apparatus and streaming equipment are copied the present invention relates to one kind.Wherein, it includes copying preceding stock tank and being arranged on copying copy preceding fluid level transmitter on preceding stock tank to copy preceding stock tank online concentration control apparatus, copy preceding stock tank have for be input into slurry enter to starch path and for export slurry for online pulp path, be provided with path into stock pump entering to be starched, stock tank pump before copying is provided with the pulp path and for adjusting pulp path in slurry concentration the first slurry concentration adjusting apparatus, copying preceding fluid level transmitter can detect the slurry liquid level copied in preceding stock tank and the conveying capacity for controlling into stock pump, so that the slurry liquid level copied in preceding stock tank keeps being basically unchanged.Copying the unlikely change because copying preceding stock tank liquid level of preceding stock tank pump causes to copy the change of preceding stock tank pump duty, first slurry concentration adjusting apparatus only has one variable of concentration when the slurry concentration of pulp path is adjusted, adjust accurately and reliably, so as to reliably ensure the online concentration of slurry.
Description
Technical field
Preceding stock tank online concentration control apparatus and streaming are copied the present invention relates to pulp manufacture technical field, more particularly to one kind
Equipment.
Background technology
The manufacture paper with pulp master operation flow of flow of slurrying includes：Get the raw materials ready, pulping, screening purification, fine grinding, metering and mixing, stream
Give, upper net forming, squeezing, drying and other steps.Before upper net forming, finished product slurry first passes through plain boiled water dilution, then by starching pump
Head box is pumped to, then paper is prepared into by upper net forming, squeezing, drying and other steps.
Approach system refers exclusively to fan pump circulation loop, paper stock is measured in the loop, is diluted and necessary auxiliary agent
Mix and screened and purified before last online.Ensure online concentration stabilization be also approach system vital task it
One.
Existing copying is simply to set two position in preceding stock tank, feed is stopped when high-order, feed supplement during low level so that before copying
Liquid level is changed greatly in stock tank, cause to copy preceding stock pump (being originally to determine frequency pump) to enter to starch pressure change big, so as to cause output to dense
The mass flow change of tune greatly, the change that both flow and concentration bring need to be processed during dense tune work, it is impossible to accurate regulation.
The content of the invention
To overcome above technological deficiency, present invention solves the technical problem that being to provide one kind copies preceding stock tank online concentration control
Device and streaming equipment, can reliably ensure the online concentration of slurry.
In order to solve the above technical problems, copying preceding stock tank online concentration control apparatus the invention provides one kind, it includes copying
Preceding stock tank and it is arranged on copies and copy preceding fluid level transmitter on preceding stock tank, copying preceding stock tank has to enter to starch path for being input into slurry
With for exporting slurry for the pulp path of online, be provided with path into stock pump entering to be starched, be provided with the pulp path before copying
Stock tank pump and the first slurry concentration adjusting apparatus for adjusting slurry concentration in pulp path, copying preceding fluid level transmitter can detect
The slurry liquid level in preceding stock tank and the conveying capacity for controlling into stock pump are copied, so that the slurry liquid level copied in preceding stock tank keeps substantially not
Become.
Further, also including the first flowmeter being arranged on pulp path, first flowmeter is capable of detecting when that slurry is logical
The pulp flow on road simultaneously controls to copy the conveying capacity of preceding stock tank pump, so that the pulp flow of pulp path and preset flow basic
Cause.
Further, first flowmeter is arranged on the downstream for copying preceding stock tank pump.
Further, the first slurry concentration adjusting apparatus includes the first densimeter and the first dilution water pipe, the first densimeter
It is arranged on and copies between preceding stock tank pump and first flowmeter, the first dilution water pipe is arranged on the upstream for copying preceding stock tank pump, first flow
Meter can control to copy the conveying capacity of preceding stock tank pump, so that the pulp flow of pulp path is basically identical with preset flow.
Further, enter stock pump and copy preceding stock tank pump and be variable frequency pump.
Further, also enter slurry stream into slurry path for detecting including the second flowmeter being arranged on slurry path
Amount.
Further, second flowmeter is arranged on the downstream into stock pump.
Further, also including being arranged on slurry path and for adjusting the second slurry of the slurry concentration into slurry path
Concentration adjusting apparatus, the second slurry concentration adjusting apparatus includes the second densimeter and the second dilution water pipe, and the second densimeter is arranged on
Enter between stock pump and second flowmeter, the second dilution water pipe is arranged on the upstream for copying preceding stock tank pump.
Further, also including machine chest, for preceding stock tank offer slurry is copied, entering stock pump as machine chest into stock pump
It is connected with machine chest.
Further, also including be arranged on machine chest into slurry fluid level transmitter, into slurry fluid level transmitter can detect
The slurry input quantity in slurry liquid level and control input machine chest in machine chest, so that the slurry liquid level in machine chest keeps base
This is constant.
Present invention also offers a kind of streaming equipment, it includes above-mentioned copying preceding stock tank online concentration control apparatus.
Further, also including header box, pulp path is communicated with header box.
Thus, based on above-mentioned technical proposal, the present invention copies preceding stock tank and surfs the Net concentration control apparatus by the stock tank before copying
Preceding fluid level transmitter is copied in setting, and the first slurry concentration adjusting apparatus is set on pulp path, and copying preceding fluid level transmitter can examine
The slurry liquid level in preceding stock tank and the conveying capacity for controlling into stock pump are copied in survey, it is ensured that copies preceding stock tank enters to starch flow and pulp flow base
This is consistent, and making to copy the unlikely change because copying preceding stock tank liquid level of preceding stock tank pump causes to copy the change of preceding stock tank pump duty, thus copies
The pulp flow of preceding stock tank ensures that the first slurry concentration adjusting apparatus is adjusting the slurry of pulp path by copying preceding stock tank level stability
There was only one variable of concentration during material concentration, adjust accurately and reliably, so as to reliably ensure the online concentration of slurry.
