Adjustable recycled slurry baffle plate

Abstract

The invention discloses an adjustable recycled slurry baffle plate, which belongs to the technical field of headboxes, and comprises a cover plate and a lip connecting piece, the side wall of the lip connecting piece is provided with an overturning shaft, the overturning shaft is clamped with a movable bracket, a front-back adjusting assembly is arranged between the movable bracket and the cover plate, and the bottom of one end of the cover plate is provided with a return pipe. The bottom of the other end of the cover plate is bolted with a triangular plate, the triangular plate is provided with a macromolecule plate and connected with a left-right adjusting assembly, the bottom of one side of the cover plate is provided with an outer spraying pipe, the top of the other side of the cover plate is provided with an inner spraying pipe, and the outer spraying pipe and the inner spraying pipe are both provided with a plurality of nozzles. The front-back position and the left-right position of the macromolecule plate can be adjusted through the left-right adjusting assembly and the front-back adjusting assembly, water sealing is conducted through the inner side spraying pipe and the outer side spraying pipe, when an inlet of the return pipe moves to the range of a nozzle of the headbox, slurry on the two sides can be directly recycled through the return pipe, and the movable support is driven to rotate through the overturning shaft, therefore, the device is overturned upwards, and the screen plate is convenient to replace.

Description

technical field [0001] The invention relates to the technical field of headboxes, in particular to an adjustable recycled slurry baffle. Background technique [0002] The headbox is a key part of a modern paper machine. Its structure and performance play a decisive role in the formation of the paper sheet and the quality of the paper. At present, the baffle plate used in the headbox can only block the edge pulp and pass through the polymer Water is injected into the board in the form of a water seal to keep the slurry from spreading out, which makes the evenness of the two sides of the paper poor, and there are more waste papers that need to be trimmed. At present, the pulp board can only move back and forth and block The distance between the bottom of the pulp plate and the screen surface is only a few millimeters, which makes it complicated and difficult for the machine to change the screen. Contents of the invention [0003] In view of the above-mentioned technical def...
