Description
Technical field
The utility model provides a kind of dilution water head box, relates to the papermaking equipment field, relates in particular to a kind of paper and manufactures paper with pulp and regulate slurry concentration by adding dilution water in the process, improves the head box of paper cross direction ration distribution consistency degree.
Background technology
Head box is as a mortar distributor of paper machine, provides finely dispersed slurry stream to the cylinder mould of paper machine, is one of most important equipment that causes paper fibre institutional framework quality, and decision paper cross direction ration evenly distributes, and directly influences the forming quality of paper.
At present, the doctor-roll head box that paper industry adopted can not be regulated the paper cross direction ration mostly, under the situation of slurry stream concentration that enters pulp-inlet pipe and constant airspeed, when paper somewhere horizontal quantification has departed from standard quantitative, can not carry out local slurry regulates, improve the paper cross direction ration, thereby can't guarantee the forming quality of paper.And the paper machine of domestic introduction now adopts the dilution water head box mostly, can effectively improve the paper cross direction ration, but because of its price is very expensive, the general user is difficult to accept.
The utility model content
In view of this, the purpose of this utility model is to provide a kind of dilution water head box, and is simple in structure, and the investment cost is few, and homogenate is effective, can improve the head box of paper cross direction profiles simultaneously again effectively.
The technical scheme that the utility model adopted is: a kind of dilution water head box, comprise pulp-inlet pipe, homogenate case, grout outlet, fixed support part and be arranged on pulp-inlet pipe and the homogenate case between the dilution water device, wherein
Described dilution water device comprises water inlet manifold, control valve and dilution water pipe, water inlet manifold is the water pipe of cone, its caliber is successively decreased by water inlet terminad successively, water inlet manifold is arranged at the top of head box casing, and a plurality of dilution water pipes are connected to the stock inlet of pulp-inlet pipe by water inlet manifold by control valve.Dilution water is entered in the stock inlet of pulp-inlet pipe through the dilution water pipe by the inflow of control valve adjusting water inlet manifold, is mixed in the homogenate case through the homogenate pipe.
Be provided with homogenate pipe and doctor-roll in the described homogenate case, the homogenate pipe is connected with stock inlet, the bore of homogenate pipe is less than stock inlet, its link is set to the conical surface, make dilution water and slurry fully be mixed into the homogenate case via the conical surface and homogenate Guan Houneng, homogenate tank inlet to doctor-roll is the gradual-enlargement type structure, and doctor-roll to grout outlet is tapering type structure.
Described grout outlet is arranged at the cylinder mould top of paper machine, comprises labial lamina up and down, and the aulaeum level is close to setting and cylinder mould top, and the opening adjuster on top lip of slice and the bearing joins, and can control the opening amount of upperlip plate by the opening adjuster.
Further, described pulp-inlet pipe is the pulp-inlet pipe of cone, and terminad successively decreases its caliber by entering the mouth successively.
Further, described doctor-roll which is provided with several roller holes, and doctor-roll rotates the eyelet that slurry flows to out the roller hole, is shunk and spreads, and slurry is dispersed.
The disclosed dilution water head box of the utility model is to utilize the water supply pipe structure of cone that differential pressures such as dilution plain boiled water carries out are supplied water, when the horizontal quantification in paper somewhere has departed from standard quantitative, manual adjustments dilution water valve opening, the slurry that enters the head box tube bank is diluted, and adopt doctor-roll evenly to mix abundant homogenate, reach the purpose of improving the page Local Quantitative, thereby improve view picture page cross direction ration; Simultaneously, make the even and fluid stable of fiber dispersion in the slurry stream, it is poly-not produce wadding, and the quantitative difference of banner after paper is shaped is little.
