Description
Technical Field
[0001] The utility model relates to the technical field of headboxes of paper machines, in particular to a water dilution device for a headbox of a paper machine. Background Technique
[0002] The headbox is a key part of a modern paper machine. It is located at the front end of the paper machine, and its main function is to send the pulp to the forming wire with a uniform distribution, stable pressure and speed, providing necessary conditions for the good formation of the paper.
[0003] During the use of the headbox of the paper machine, it is necessary to dilute the fibers inside the headbox of the paper machine. Dilution water is often added to the inside of the headbox of the paper machine for dilution. After the water flow enters the headbox, it is mixed with the fibers through the fluidity of the water flow itself. This process takes a long time, resulting in a decrease in the fiber dilution speed. If the mixing time of the water flow and the fibers is too short, the water flow will not dilute the fibers sufficiently, affecting the fiber dilution effect and the subsequent processing quality of the paper. Content of the Utility Model
