    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. However, in the design for complete dissolution of the waste paper, it is required that the rotary drum of the resolution area be provided for a very long time. With an insufficient length of the resolution range, the processing time of the waste paper within the drum body is relatively short and there is no complete resolution. After being placed in the screen area, large amounts of waste paper are removed along with the debris, which is a huge waste. As a result, the entire device has extremely large dimensions and a large footprint with excessive material consumption and high rotational load, which in turn leads to high manufacturing and operating costs.
    The Chinese patent CN199621301U relates to a drum pulper-type pulper, which consists of two wheel rotators and a gear-driven long pulley. Waste paper, water, and other starting materials are continuously fed from the top of the drum and experience friction, impact, and dissolution into fibers through the cutting plates provided in the drum. Subsequently, the feed takes place in a lower sieve area, wherein the sieve carries the useful mass into the storage tank, while the foreign bodies, if they have not been crushed, are removed as large pieces of the sieve. This increases recycling benefits and reduces energy consumption. Thus, it is a novel device for the automatic and continuous production of paper pulp from waste paper on a large scale. However, in this apparatus, the residence time of the mass within the drum can hardly be ensured with too fast circulation, resulting in the deterioration of resolution effect and resolution efficiency. In addition, the screen plate is vertically attached to the inner wall, which causes no optimal effect and also causes a deterioration of resolution effect and resolution efficiency.
    The Chinese Utility Model CN203212922U relates to a rotary drum type pulper-dissolving apparatus comprising a drum body with possible rotation, the drum body comprising a material input port and a material discharge port, a plurality of blade plates being fixed to the inner wall of the drum body a plurality of groups of blade plates in the circumferential direction of the above-mentioned drum body are provided at a distance from each other, wherein the blade plates of the same group are arranged in one and the same circumferential direction. In the subject rotary drum type pulper-dissolving apparatus, the formation of an over-long pigtail can be prevented, which has a positive effect on increasing the dissolution efficiency. In addition, the productivity of the rotary drum type pulper-dissolving apparatus is increased per se. However, the arrangement of the cutter plates in the rotary drum type pulper-dissolver according to the above-mentioned utility model is not ideal and the dissolution effect remains suboptimal.
