Description
Technical field
The utility model relates to a kind of paper machine forming net cleaning swivel head more particularly to a kind of forming net high-pressure rotaries
Head sealing mechanism.
Background technique
Paper-making industry is that China Today consumption Environmental costs are big and actual demand amount also big one of industry, although internet skill
Art is advanced by leaps and bounds, but being continuously advanced with the rapid development of China's economic and global economy, and China and the world are to the total of paper product
Demand also slightly increases, the demand to paper product there is no changing, it is meant that the demand to paper making pulps, and prepare paper grade (stock)
The forest growth rate of slurry is far below the demand depletion rate of paper making pulps, under the premise of paper products total output is constant, how
Paper making pulps consumption is reduced, and the paper of high-quality can be produced, has been one of global problem pendulum in face of the mankind.
Based on above-mentioned, people, which are studying always, finds high filler paper production technology and its production equipment, is solved early with it
Open above-mentioned problem.Paper machine is the joint equipment of paper making, and there are mainly three types of types for conventional paper machine: long mesh paper making machine, cylinder
Paper machine, foudrinier.Wherein long mesh paper making machine is a kind of widely used paper machine type, and can manufacture paper with pulp most of paper product
Kind, it is the mainstream model of paper machine.
