    In the dryer section of a paper making machine, the paper web is pressed against the drying cylinders by means of an air-permeable endless support band. An air blast apparatus extends transversely of the paper making machine and creates an air flow which is directed generally across and through the support band and onto the paper web. The air blast apparatus has at least one blow orifice in the form of a ring slot with two longitudinal slots extending generally longitudinally of the air blast box or housing of the air blast apparatus, and at least generally transversely of the paper web and the support band. The blowing directions of the two longitudinal slots may be at different angles with respect to the running direction of the support band.

    专利说明:

    The invention relates to a duct for blowing air into the drying section of a paper machine and is intended for use in the pulp and paper industry. The purpose of the invention is to reduce energy consumption while simplifying the design of the box. Fig. 1 shows a drying part of the machine with a duct, a schematic section, in Fig. 2, view A in Fig. 1; FIG. 3 shows a quadrangular opening, partial section J in FIG. 4, the internal space of the housing, partial section. The air blower box in the drying section of the papermaking machine comprises a housing 1 extending transversely to the direction of movement of the endless air permeable supporting the paper web of the tape 2 through the inner space 3 of the loop formed by the tape covering one row of drying cylinders 4 and deflecting means 5 and having in the wall of its annular slotted opening 6 in the form of a quadrilateral a part of which is formed by two longitudinal slotted openings along the longitudinal direction of the housing 7, Assumption during the travel of the web, and the openings 8 disposed along the length of the housing for applying air flow to the paper web through the support tape. The openings 8, located along the body length, are made in the shape of an annular slotted opening 6, the annular slot opening being located in a row with openings along the length of the body and in each of the openings axis 9 of the longitudinal slotted opening of the supporting tape 2 with the direction of its movement, the angle is 70-110, and the axis 10 of the second longitudinal slotted hole located behind the first one along the movement of the paper web makes an angle of 100-140 ° with the direction of its movement. The inner space 3 of the hinges (the so-called pocket) is limited by the drying cylinder 11, the paper web and the supporting tape 2. The box is located closer to the drying cylinder 4, from which the tape 2 runs off. In this area, the housing 1 box has holes, ; providing 302 airflow to the web so that hot air flows through the support belt into the pocket in this area. FIG. 3 shows the direction of injection or the axis 9 of the longitudinal slotted hole 7 ,. located first in the course of the movement of the supporting tape 2, makes an angle o with the direction of its movement. (mostly my pr). However, this angle may be from. 70 to 110 °. . The direction of injection or the axis 10 of the longitudinal slotted hole 7, located behind the first one in the direction of movement of the paper web, constitutes with the direction of its movement an obtuse angle b, which is generally 100-140 °. FIG. 4, the inner space of the housing is divided by means of transverse walls 12 into separate chambers so that each opening has its own camera. Each chamber may have a separate air duct. In Fig. 2, only one supply duct 13 is shown. The making of the apertures 7 according to the invention has the advantage that the duct can also be located at a relatively large distance from the nearest drying cylinder 4. Due to this, when a marriage occurs, there is no danger that the tape 2 will come into contact with the duct. The transverse slotted holes .14 of the openings 6 and 8 are so inclined that the injection through them occurs inside the floor bounded by these openings (figure 4). In order, if possible, all the air leaving the box passes through the tape 2 into the pocket 3, a sealing strip 15 is provided at the lower end of the box, in contact with the deflecting means 5 (roller). The openings 6 and 8 are made annular slit and can take the form of a parallelogram, trapezium and other various forms. The device works as follows. The paper web to be dried is alternately guided through the cylinders 4 and cylinder 11, while it is pressed together with the supporting tape 2 against the cylinders 4. Between every two cylinders 4 the tape 2 passes through the deflecting means 5. In the running away zone of the supporting tape 2, from cylinder 4, hot air flows through the tape into the pocket 3 of the annular slotted openings 6 and 8. On the basis of a certain pumping effect of the supporting tape in the pocket, an air flow is indicated, indicated on arrows 1 and. The air comes out of the pocket on the back of the box through the tape up. By making the air blowing box according to the invention, the humidity adjustment is repeated. The box is not structurally complex in design and provides less energy while efficiently blowing pockets. Formulas for the invention 1. A box for blowing air into the drying part of a papermaking machine, comprising a body extending across the direction of movement of an endless, air-permeable, supporting the paper web of the tape through the inner space of the loop formed by the ribbon enclosing one p d of drying cylinders and deflecting means, and having in the wall of its annular slotted opening in the form of a quadrangle, part of which is formed by two longitudinal slotted along the longitudinal direction of the body and openings located along the motion of the web and openings located along the length of the body, providing air flow to the paper web through the supporting tape, characterized in that, in order to reduce energy consumption during construction growth, openings located along the length of the body is made in the form of an annular slotted opening, with an annular slotted opening located in a row with openings along the length of the body and in each of the openings the axis of the longitudinal slotted opening located first in the direction of movement With the tape, the angle 70 70 110 with the direction of its movement, and the axis of the second longitudinal slotted hole located behind the first one along the movement of the paper web, makes an angle of 100-140 with the direction of its movement. and with the fact that the annular opening has the shape of a parallelogram. 3. Box POP.1, characterized in that the annular slotted opening has the shape of a trapezoid. 4. Box POP.1, characterized in that the housing has a sealing strip in contact with the deflecting means.
