Crescent double-layer flow box

Abstract

The invention discloses a crescent double-layer flow box which comprises a box body arranged on a base. The top end of the box body is covered by a box body cover, one side of the box body is connected with a slurry inlet main pipe, the other side of the box body is provided with a lip area, the lip area continuously and gradually narrows down and is formed by converging an upper lip plate and a lower lip plate, the tail end of the lip area is opposite to a slurry feeding position formed by a forming roll and a breast roll, a first slurry distributor and a second slurry distributor are arranged in the box body, the slurry inlet main pipe comprises an upper surface slurry square taper main pipe and a lower bottom slurry square taper main pipe which are parallelly arranged, the lip area is divided into an upper lip area and a lower lip area through a flow sheet, an input end of the first slurry distributor is connected with a first truncated square taper slurry inlet connection pipe of the surface slurry square taper main pipe, an output end of the first slurry distributor is connected with the upper lip area, an input end of the second slurry distributor is connected with a second truncated square taper slurry inlet connection pipe of the bottom slurry square taper main pipe, and an output end of the second slurry distributor is connected with the lower lip area. Two types of slurry can be led into the crescent double-layer flow box, so that the ratio of the two types of slurry can be accurately controlled.

Description

technical field [0001] The invention relates to the technical field of the pulp flow delivery system of a tissue machine, in particular to a crescent-shaped double-layer headbox. Background technique [0002] Both toilet paper and paper towels represent a wider range of paper products. They are mainly used for personal consumption and public consumption. Toilet paper, napkins, facial tissues, paper towels, etc. have been integrated into people's lives and are indispensable. With the development of the times, people's requirements for the quality of toilet paper are getting higher and higher. If enterprises want to achieve better development, improving the quality of their toilet paper brands is the basis for winning the market, and at the same time effectively improving their own production efficiency and work quality is the key. important means. The main trend of tissue machine is to develop towards faster speed, higher efficiency and better quality. [0003] All kinds of...
