Description

Circulation can be regulated net cage in the cylinder effluent

Technical field

The utility model relates to pulp technology for making paper, specifically, is that circulation can be regulated net cage in a kind of cylinder effluent.

Background technology

What the one-tenth paper step in the present domestic paper industry generally adopted is a kind of cylinder former, but its principle is to allow the filtration cylinder of a rotation carry out rotation on one side, make the surface of upstream paper pulp stream on one side through this cylinder, by gravity filtration, make fiber in the paper pulp etc. be deposited in the cylinder surface and be carried out to paper, l Water Paper layer after the shaping is along with the rotation of cylinder can further be gone out by the volume drawstring, and the moisture in the paper pulp then filters through cylinder and takes away.Paper pulp in general traditional cylinder equipment is direct current or the whitewashing formula dehydration work up and down of doing in net cage, because when starching becomes paper, pulp liquor has same flow direction property on the cylinder surface, add that cylinder itself has rotation, therefore also can on same angle value, distribute at the paper fibre of retaining on the cylinder surface, promptly show as and have single direction, show on the sheet paper products behind the paper, it is vertical, the tensile strength of horizontal ratio and tearability, the gap value performance is very big, promptly tensile strength is very big longitudinally, and laterally often very without drawing, is unsuitable in some specialties type that the quality index requirement is arranged.Present stage will be produced stressed in length and breadth uniform paper, is subjected to the restriction of legacy equipment structure, and difficulty is still very big.

The utility model content

The purpose of this utility model is in order to overcome above-mentioned deficiency of the prior art, provides in a kind of cylinder effluent that improves lateral stressed paper circulation can regulate net cage, but and a kind of automation be combined into the cylinder mould machine of paper.

To achieve these goals, the technical scheme taked of the utility model is:

Circulation can be regulated net cage in a kind of cylinder effluent, but the cylinder that comprises a rotation, head box is located at the upstream of cylinder, its base plate is provided with the parallel heavy skin of strip shape, the first half of heavy skin and cylinder intersects, play sealing and guide functions, described head box has been divided into the plural at least cavity that distributes before and after being by dividing plate, makes the paper pulp in the cavity in twos do reciprocal internal-circulation type motion.

As further improvement of the utility model, described dividing plate is movable, can before and after do to regulate to change the volumetric ratio in described continuous front and back two cavitys.

As further improvement of the utility model, the porch in the dehydration chamber that contacts with cylinder is provided with the flashboard of adjustable throttle amount.

As further improvement of the utility model, the rear of described flashboard is provided with adjustable slurry stream pump, to improve slurry flow rate.

As further improvement of the utility model, described heavy micromicro is parallel to cylinder and does axial asymmetric height adjusting, with the intersecting lens of change with the cylinder external peripheral surface, and then the drinking water volume of change cylinder horizontal quantification.

As further improvement of the utility model, highly have at least the end can up-down adjustment about described base plate, promptly be parallel to cylinder and can make axioversion, with the flow through speed of its surperficial pulp liquor of change.

As further improvement of the utility model, described head box has been divided into former and later two cavitys by dividing plate; The two ends of described head box also have been provided with the buffer unit that relaxes guiding backflow effect.

As further improvement of the utility model, described buffer unit is an arc deflector, and its inner chamber communicates with two chambeies, described front and back.

The utility model also provides a kind of cylinder mould machine, and the interior circulation of above-mentioned cylinder effluent that includes more than at least one can be regulated net cage, and circulation can be regulated the below that net cage is arranged in parallel within the paper feed woollen blanket that is driven by transfer roller in the above-mentioned cylinder effluent; The top of cylinder is provided with the platen couch roll and compresses described woollen blanket.

As further improvement of the utility model, the quantity that the interior circulation of described cylinder effluent can be regulated net cage is 2.

The operation principle of the utility model net cage is the effluent internal-circulation type, the direct current up and down of net cage and the dehydrated structure of whitewashing break traditions, the paper pulp of doing to circulate in head box is the flow direction that is lateral flow type with the cylinder face, cooperate the rotation of cylinder, make fiber in the paper pulp present the surface that certain angle of inclination resides in cylinder and be carried out to paper; The dividing plate of activity in the head box cooperates flashboard, the flow-rate ratio of pulp liquor in two chambeies before and after can regulating, and then the flow velocity of adjusting sizing liquor; The turbulent flow phenomenon of pulp liquor in the starching porch avoided in the backflow that the buffer unit that communicates with two chambeies can be spared the cloth pulp liquor, to cause the skewness that flows to of fiber; The base plate tiltable of head box changes the flow velocity of sizing liquor, the heavy skin of engages adjustable height again, regulate the contact size of stream slurries on the cylinder face by heavy skin position, and which kind of guiding of the even cloth of flow liquid, and then change the distribution value of paper on horizontal quantification; Be equipped with adjustable slurry stream pump, improve the flow velocity of paper pulp when starching on the one hand, change the lateral stressed value of paper, improve the flow liquid circulation rate on the other hand, promote production efficiency.

The cylinder mould machine that utilizes the utility model to be assembled into, flowing in the different above-mentioned cylinder effluents circulation by two groups can regulate net cage and form, the paper feed woollen blanket that drives by transfer roller drives into paper, carry out the step of the antipodal above-mentioned one-tenth paper of twice direction, can form a kind of sheet paper products of staggered fiber grain.This product vertical, horizontal pulling force can be brought up to 5: 3～5: 4 after testing; Even can be near 5: 5; Simultaneously producing identically quantitatively and under the situation of the door width of cloth, the speed of a motor vehicle (output) has also improved 20%～30% than original.
