Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0025] see Figure 1 to Figure 4 . An embodiment of the present application provides a pulp leveling device for a cylinder paper machine, which may include: a first turbulence mechanism 13, on which a first tip 11 extending downward is provided; the first tip 11 is used to extend into the top of the homogenizing tank 19; to change the flow direction of the slurry 21 in the top of the homogenizing tank 19, so that the fibers of the slurry 21 in the top of the homog...

Abstract

The invention provides a slurry leveling device of a round screen paper machine. The slurry leveling device of the round screen paper machine can include a first turbulent flow mechanism and a secondturbulent flow mechanism, a first tip extending downwards is arranged on the first turbulent flow mechanism; the first tip is used for extending into the upper part of a slurry leveling groove to change the flow direction of slurry on the upper part of the slurry leveling groove, so fibers of the slurry in the upper part of the slurry leveling groove can be evenly distributed in a transverse direction; a second tip extending upwards is arranged on the second turbulent flow mechanism; the second tip is located on the side lower part of the first tip; the second tip is used for being placed in the lower part of the slurry leveling groove to change the flow direction of the slurry on the lower part of the slurry leveling groove, so the fibers of the slurry in the lower part of the slurry leveling groove can be distributed evenly in a transverse direction; and the first turbulent flow mechanism is a first turbulent flow roller extending horizontally, and the transverse section of the firstturbulent flow roller is in a water-drop shape, and the lower part of the first turbulent flow roller forms the first tip. The invention provides the slurry leveling device of the round screen papermachine which can be installed in narrow space and can dissipate energy and level the slurry.

Description

technical field [0001] The invention relates to the technical field of papermaking, in particular to a pulp leveling device for a cylinder paper machine. Background technique [0002] A cylinder paper machine is used to shape the stock to produce paper. With the increase of the speed of the rotary paper machine, the sizing speed of the rotary paper machine is getting higher and higher. Excessively high sizing speed makes the kinetic energy of the slurry large, and produces a large number of vortices and backflows in the network groove, disturbing the normal slurry flow shape, resulting in uneven distribution of the slurry in the transverse direction of the paper web, which in turn leads to reduced paper forming quality and watermark clarity. and poor consistency. [0003] In the prior art, a homogenizing roller is usually used to level the slurry. However, the space at the front of the network tank of the rotary paper machine is narrow, specifically, the size of the space...
