    PULPER RESOLUTION DEVICE IN TURN DRUM MANUFACTURING TECHNICAL FIELD
    The present utility model relates to a plant for the production of pulp in the technical field of papermaking plants, in particular a pulper-dissolving device in rotary drum design.
    STATE OF THE ART
    In the papermaking industry, pulper-dissolving devices are used to dissolve waste paper into fibers. By means of a pigtail device coarse coiled foreign bodies are pulled out of the pulper-dissolving device, whereby the removal of the foreign body takes place regularly by means of a cutting-off device. As the mass dissolves, coarse and heavy material concentrates at the bottom of the sediment tank and is directed into the foreign matter separator via an overflow port. Under the action of its rotor, the useful mass is passed through a sieve plate to the next step. The coarse foreign bodies remain in the foreign matter separation device, are regularly passed through a drum screen with pressurized water, and emitted after removal of the water. The sedimented at the bottom of the sediment container heavy foreign body are regularly removed with Krreifreifern. The device is complicated with high energy consumption, high damage rate, difficult handling and certain losses of waste paper fibers.
    The rotary drum pulper-type dissolver is a significant plant for recovering mass from waste paper. In a conventional rotary drum type pulper-dissolving apparatus, the drum body mainly has the two constituent areas of material input and screening. The area of dissolution comprises a circular bucket made of steel, on the inner wall of which longitudinally welded vertical plates act as knife plates, with an apertured separating plate disc being provided on the outside. In operation, water spraying occurs under high external pressure, so that the separation of the useful mass from the waste material is carried out.
    Figure 1 is an illustration of a conventional rotary drum type pulper-dissolving apparatus with the sealing structure provided at the end of the material input port, wherein a statically immobile material input groove is connected to the rotary drum body of the rotary drum type pulper-dissolving apparatus. The seal member 8 attached to the material input groove is connected by screws to the seal member 8 attached to the drum body so that the two seal members form a V-shaped groove. Subsequently, by means of a sealing cable 9, the seal around the upper part. The type of sealing can be done from clock point 1 o'clock to clock point 11 o'clock, or another type of sealing can be made. The end of the sealing cable 9 is guided by a sliding led out by a weight, so that the sealing cable preserves the V-shape.
    By this kind of sealing of the material input end of a conventional pulper-dissolving apparatus in rotary drum type, the sealing member fixed to the drum body continuously has friction with the static sealing cord. As operations progress, more and more fillers, dust, plastic, cable ends, and other debris enter the sealing area between the seal members, and the seal members experience increasing friction with continuous damage to the sealant cord. In order to maintain a good sealing effect, the sealing cable and the sealing parts must be replaced frequently, and the service life of the rotary drum type pulper-dissolving apparatus is also impaired.

    The figures show preferred practical embodiments of the present utility model. A further description of the present utility model will be given with reference to the accompanying drawings: Figure 1 is an illustration of the seal construction at the material input port of a conventional pultrusion apparatus in rotary drum design. A statically immobile material input groove is connected to the rotatable drum body of the rotary drum type pulper dissolver. The seal member attached to the material input groove is connected by screws to the seal member fixed to the drum body, so that the two seal members form a V-shaped groove. Subsequently, by means of a sealing cable, the seal around the upper part. The type of sealing can be made from clock point 1 o'clock to clock point 11 o'clock, or a different type of sealing can be made. The end of the sealing cable is pulled out by a sliding roller guided by a weight, so that the sealing cable preserves the V-shape.
    By this kind of sealing of the material input end of a conventional pultrusion apparatus in rotary drum type, the sealing member fixed to the drum body continuously has friction with the static sealing cord. As operations progress, more and more fillers, dust, plastic, cable ends, and other debris enter the sealing area between the seal members, and the seal members experience increasing friction with continuous damage to the sealant cord. In order to maintain a good sealing effect, the sealing cord and the sealing members must be replaced frequently, and the life of the rotary drum type pulper-dissolving apparatus is also deteriorated.
    As shown in Figs. 2 and 3, the present utility model relates to a rotary drum type pulper-dissolving apparatus. The rotary drum type pulper-dissolving apparatus comprises a drum body with possible rotation, the drum body having the dissolution and / or screening having a material input port and a material discharge port, wherein the above-mentioned material input port is a material input port 1 and one between the drum body 2 and the material input port 1 labyrinth seal construction.
    It can be seen from Figure 2 that the head part of the material input groove 1 extends into the drum body of the rotary drum type pulper dissolver. The above-described labyrinth seal construction is located between the drum body 2 and the material input groove 1. Above the sealing structure concerned, there is provided a spray tube 3, the spray area of the above-described spray tube 3 being 210 ° in the circumferential direction. The spray tube 3 may spray on the sealing area to flush foreign matter so that it no longer remains in the sealing area. Since the material input groove is inclined and is in communication with the drum body of the rotary drum type pulper-dissolving apparatus, the cross-section of the material input groove is not circular.
    Figure 3 is an enlargement of the position W of the seal construction of the rotary drum type pulper-dissolving apparatus of the present invention. It can be seen from the figure that two sealing plates 6 are provided on the outer wall 4 of the material input groove, while a sealing plate 7 is provided on the inner wall of the drum body, the above-mentioned three sealing plates having no contact with each other and forming a labyrinth sealing structure having a sealing effect.

The inner ring of the sealing plates 6 provided on the outer wall 4 of the material input groove is fixedly connected to the outer wall 4 of the material input groove. The outer ring of the attached to the inner wall 5 of the drum body sealing plate 7 is fixedly connected to the inner wall 5 of the drum body. The seal plate 7 fixed to the inner wall 5 of the drum body is located at the middle position of the two seal plates 6 fixed to the outer wall 4 of the material input groove. The two seal plates fixed to the material input groove are provided in parallel with each other, and the two seal plates 6 fixed to the material input groove are parallel provided to the provided on the inner wall of the drum body sealing plate 7.
    It is also provided that in the first dissolution section of the drum body of the above-described pulper-dissolving device in rotary drum design, a material transport element is provided which comprises a material lifting plate and / or a blocking plate, and / or a knife plate. In operation of the rotary drum type pulper-dissolving apparatus, the above-described material transporting member serves to transport the mass away from the material input port.
    The provided in the first dissolution section of the drum body of the above-mentioned pulper-dissolving device in rotary drum design Materialhebeplatte is provided inclined in the axial direction, which has a positive effect on the easier supply of the liquid in the material inlet liquid flowing into the drum body. At the same time it prevents that too much water and liquid mass get into the sealing area.
    Through the explanations and the accompanying drawings typical constructions of practical embodiments have been shown. However, the illustrations of these preferred practical embodiments of the present utility model do not imply any limitation on the contents of the present utility model. A person skilled in the relevant technical field can undoubtedly make modifications and modifications after having read the above description.
