Problems solved by technology

But there are two problems. First, the dilution water with very small solid content is added in the second stage of fine-tuning process. Cross-flow is generated, which affects the adjustment effect and the fiber orientation of the paper; secondly, in the second section, the dilution water branch pipe is still installed between the branch pipes of the turbulent flow generator, and its installation is affected by the distance between the turbulent flow branch pipes, and increases the processing manufacturing difficulty

Embodiment Construction

[0021] The present invention will be further described below in conjunction with the accompanying drawings, but the present invention is not limited thereto.

[0022] like figure 1 As shown, the dilution water is added to the headbox in two stages. The headbox includes a dilution water coarse adjustment system and a dilution water fine adjustment system. The dilution water coarse adjustment system consists of a dilution water main pipe 1, a regulating valve 2, a dilution water branch pipe 3 and a dilution water The dilution water fine-tuning system is composed of a dilution water main pipe 7 , a regulating valve 6 , a dilution water branch pipe 5 and a dilution water module 4 .

[0023] The dilution water main pipe (1, 7) is a tapered pipe, which can ensure that the flow and pressure entering the dilution water branch pipe (3, 5) are completely equal. The two sets of dilution water addition systems share a dilution water module 4, the first section of coarse adjustment diluti...

Abstract

The invention discloses a paper width quantitative device of coarse tuning and micro-turning diluted water, which comprises the following parts: main pipe of diluted water, adjusting valve of diluted water, branch pipe of diluted water and diluted water mode, wherein the diluted water mode is set between paste inlet pipe of paste flowing box and distributing pipe beam; two cases of main pipe of diluted water, adjusting valve of diluted water and branch pipe of diluted water use one diluted water mode, which constitutes the coarse turning system and micro-turning system of diluted water. The invention adopts reasonable adding pattern to avoid diluted water from flowing transversely in the paste-flowing box, which improves width quantitative effect and control precision of diluted water.

Description

technical field [0001] The invention relates to a headbox of a paper machine, and more specifically relates to a device for adding dilution water to coarsely adjust and finely adjust the quantification of paper banners. Background technique [0002] Today, with the continuous development of paper testing equipment, the market has put forward higher and higher requirements for the quantitative distribution of paper banners. The dilution water injection point spacing of the dilution water headbox is about 32mm to 75mm, generally around 60mm. If white water containing fibers is used as dilution water, the spacing cannot be smaller, because too small a pipe diameter will cause dilution Blockage of water branch pipes, and slightly larger branch pipes cannot be installed between denser pipe bundles. [0003] U.S. Patent US6808601B1 proposes a device that adds dilution water into the headbox in two stages. In the first stage, the dilution water branch pipe is installed after the s...
