Abstract

The utility model relates to the technical field of papermaking equipment, in particular to a novel forming roller. The novel forming roller comprises a cylindrical hollow roller face, and a plurality of radically-penetrated air outlet holes are evenly formed in the roller face. An air blowing device is arranged inside the roller face, high pressure gas is blown out from the air outlet holes. The novel forming roller improves the dehydrated effect and reduces the energy consumption of the follow-up drying processes.

Description

A kind of novel forming roller

Technical field

The utility model relates to the paper making equipment technical field, and a kind of novel forming roller specifically is provided.

Background technology

In the prior art paper machine, in molding procedure: paper pulp sprays by head box and enters in the angle of format roll and breast roll, is subjected to the squeezing action of format roll and woollen blanket.Water in the paper pulp is extruded out.Format roll runs up under the drive of woollen blanket.Water breaks away from paper pulp under action of centrifugal force.Paper is able to basic forming.

The prior art format roll is simple cylindrical roll.It is insufficient to dewater under action of centrifugal force.In follow-up operation, also need to expend a large amount of energy consumptions paper is carried out the drying processing.

The utility model content

At problems of the prior art, the purpose of this utility model is to provide a kind of dehydration sufficient novel forming roller, reduces in the subsequent handling the dry energy consumption of handling of paper.

To achieve these goals, the technical scheme of the utility model format roll is as follows:

A kind of novel forming roller of the utility model comprises the hollow roll surface of column type being laid with the exhaust vent that several radially connect on the roll surface; Roll surface inside is provided with blowing device, and gases at high pressure are blown out from exhaust vent.The two ends of described roll surface are provided with spindle nose, are used for installing bearing and connect outside power set.

Preferably, described blowing device comprises static mandrel, and roll surface can be around 360 ° of rotations of mandrel; Mandrel is provided with at least two sealing plates that contact with the roll surface inwall, and mandrel, sealing plate, roll surface form the fan-shaped blowing chamber of sealing.

Preferably, set up sealing plate in the described blowing chamber, blowing chamber is separated between several fan sections, the gases at high pressure of different pressures value are set between different fan sections.

Preferably, the fan-shaped angular range of described blowing chamber is 30 °～150 °.

A kind of novel forming roller of the utility model arranges blowing device in roll surface, blow gas acts on the woollen blanket from exhaust vent, makes the effect that format roll can accelerate to dewater in running up.The experiment proved that, use a kind of novel forming roller of the utility model can improve water separation capability 1%～2%, reduce the energy consumption 8%～12% in the follow-up drying process.

Description of drawings

Fig. 1 is for being used for the axial cutaway view of explanation the utility model format roll;

Fig. 2 is the structural representation of the A-A cutaway view of Fig. 1;

Fig. 3 is installed in the schematic diagram that uses on the paper machine for the utility model format roll.

The specific embodiment

Below in conjunction with accompanying drawing the utility model preferred embodiment is further specified:

As shown in Figure 1 and Figure 2, a kind of novel forming roller of the utility model comprises the hollow roll surface of column type being laid with several exhaust vents that radially connects 02 on the roll surface; Roll surface inside is provided with blowing device, and gases at high pressure are blown out from exhaust vent.The two ends of described roll surface are provided with spindle nose 05, are used for installing bearing and connect outside power set.

Described blowing device comprises static mandrel 04, and roll surface can be around 360 ° of rotations of mandrel; Mandrel is provided with at least two sealing plates 03 that contact with the roll surface inwall, and mandrel, sealing plate, roll surface form the fan-shaped blowing chamber 01 of sealing.

The fan-shaped angular range of described blowing chamber is 120 °.

As shown in Figure 3, a kind of novel forming roller of the utility model is installed on the paper machine, is used for the paper moulding.Paper pulp comes out by nozzle ejection from head box 1, enters in the angle of format roll 2 and breast roll 3.In the running up of format roll 2 and breast roll 3, paper pulp is clipped in forming web 4 and the woollen blanket 5 and evenly distributes.Under the centrifugal action that runs up of format roll 2, and under the blast effect of blowing chamber 01, the most of moisture in the paper breaks away from away and enters in the white water box 7.Angle a is the fan-shaped angle of blowing chamber 01 among the figure.A kind of novel forming roller of the utility model has improved the effect of dehydration, has reduced the energy consumption of follow-up drying process.
