现有流浆箱分为敞开式流浆箱(适于车速250m/min以下)、气垫式流浆箱(250~450m/min)、水力式流浆箱(500m/min)、稀释水式流浆箱(500m/min以上),但是以上这几种流浆箱都不是专门生产卫生纸用的。它们对车速和定量的变化较为敏感,而且不能生产11~17g/m2以下的原纸。CN102002879A提供了一种水力流浆箱,包括布浆、匀浆、喷浆装置,其特点是:匀浆装置由匀浆孔板、分散剂管、混合室、缩扩区、喷嘴组成,布浆装置和混合室之间设有匀浆孔板,混合室内有多个可
The existing headbox is divided into an open headbox (suitable for a vehicle speed below 250m / min), an air-cushion headbox (250 ~ 450m / min), a hydraulic headbox (500m / min), a dilution water flow Pulp boxes (500m / min or more), but these types of headbox are not specialized in the production of toilet paper. They are sensitive to changes in vehicle speed and ration, and can not produce base paper of 11 to 17 g / m2 or less. CN102002879A, a hydraulic headbox is provided, which comprises a cloth distributing, a homogenizing and a spraying device. The utility model is characterized in that the homogenizing device is composed of a homogenizing perforated plate, a dispersant tube, a mixing chamber, a shortening expanding area and a nozzle, There is a homogenization orifice plate between the device and the mixing chamber. There are several mixing chambers
