Problems solved by technology
[0003] At present, most of the homogenizing roll headboxes used in the papermaking industry cannot adjust the paper horizontal weight. When the concentration and speed of the stock flow entering the stock inlet pipe are constant, when the horizontal weight of a certain part of the paper deviates from the standard weight, it cannot be adjusted. Partial stock adjustment to improve paper banner weight, so that the forming quality of paper cannot be guaranteed, and the existing headbox can no longer meet the needs of production technology

The invention relates to a headbox for a dilution water pipe device. The headbox comprises a rack, a headbox body, a liquid regulating assembly, homogenizing rollers, a decelerating assembly, a dilution water device and a multi-pipe pulp distributing device, wherein the headbox body is arranged on the rack; the multi-pipe pulp distributing device comprises a plurality of pulp distributing branch pipes; the pulp distributing branch pipes are arranged on the lower side surface of the headbox body; the dilution water device comprises a dilution water pipe, a water inlet main pipe and a regulating valve; the water inlet main pipe is laterally arranged outside the headbox body and above the multi-pipe pulp distributing device; one end of the dilution water pipe is communicated with the upper end of the water inlet main pipe; the other end of the dilution water pipe is communicated into the headbox body. The headbox provided by the invention is easy to operate and simple in structure; by adding dilution water to each branch pipe of the multi-pipe pulp distributing device, and adjusting the flow rate of the dilution water entering the branch pipe, the density of pulp entering each part of the headbox body is adjusted, and the purpose of uniformly controlling the profile basis weight of paper is achieved.
Description
technical field [0001] The invention relates to the technical field of papermaking machinery, in particular to a headbox of a dilution water pipe device and a system using the same. Background technique [0002] As a pulp distributing device of the paper machine, the headbox provides evenly dispersed pulp flow to the cage of the paper machine. It is one of the most important equipments that cause the quality of the paper fiber structure. It determines the quantitative and uniform distribution of the paper banner and directly affects the quality of the paper. forming quality. [0003] At present, most of the homogenizing roll headboxes used in the papermaking industry cannot adjust the paper horizontal weight. When the concentration and speed of the stock flow entering the stock inlet pipe are constant, when the horizontal weight of a certain part of the paper deviates from the standard weight, it cannot be adjusted. Local stock adjustment improves the basis weight of the pa...
