    Apparatus for continuously processing wood comprises a pressurized grinding chamber, a grinding stone which is mounted for rotation in the grinding chamber, a device for feeding wood into the grinding chamber to form a primary groundwood stock therein, and a device for discharging the primary groundwood stock from the chamber without allowing gas to escape from the chamber to atmosphere. The discharging device comprises a stick crusher for crushing sticks present in the primary groundwood stock thereby to produce a secondary groundwood stock and an outlet for continuously discharging the secondary groundwood stock while preserving a hydraulic seal of groundwood stock thereby to maintain the groundwood stock in the apparatus under superatmospheric pressure.

    The invention relates to the pulp and paper industry, in particular to methods of unloading felted wood.
    The purpose of the invention is to increase efficiency.
    The drawing shows the grinder used to carry out the method.
    The defibrure comprises a frame 1, a plenum pressure chamber 2 with a device for closing the loading door and a discharge opening 3, at least one device A for forcibly feeding wood 5, mounted on a shaft 6 and a rotating grinder 7 located in the pressure chamber 2, device 8 unloading, capacity 9 for de-fibrated wood, associated with the discharge opening 3 of the chamber 2 of the increased pressure valve 10 The device for closing the loading door is made in the form of a gateway chambers 1I with two successively located top 12 and bottom-f 13 flaps holding P) waters 14, the gateway chamber 11 communicating with the atmospheric tube 15 through pressure regulator I6 and with pressure chamber 2 through tube J 7 . Chamber 2 is an increased pressure tube 19 for supplying compressed air. The tank 9 for defibrated wood is equipped with a ground mass detector 20 operating on pressure differential that is connected to the valve 10, and the bar crusher is located between the discharge device 8 and the tank 9 for defibrated wood in which the gap 21 is formed as a pulp from the defibrated wood. 22. The valve 10 is connected to the cyclone 23 and the heat exchanger 24,
    The method is carried out as follows.
    In the pressure chamber 2 filled with gas, the wood 5 is defibrated by means of a rotating shredder 7, a suspension of the defibrated wood into a mass and its unloading into a 9 dl tank of defibrated wood. Wood unloading in the form of mas0

    The syringes are pressurized through a shutter 21 formed by a mass of defibrillated wood, the shutter level being controlled by unloading the weight and controlled by the valve 10 and the differential pressure detector 20 so that the surface of the shutter 21 is always in the tank 9 at a level higher than the outlet. This layer prevents the pressure drop in chamber 2, the pressure in which, just like in tank 9, remains at a level of 0.8-3.0 bar. Before feeding the mass of defibrated wood into the tank 9, the defibrilled wood 22 is crushed in a bar crusher 22, in which the sticks, chips, and pieces of wood go through a grinding process and are ground into smaller pieces to prevent clogging of the valve 10, the temperature of the mass discharged from the tank 9 , lOO-lAO C, after which the mass is fed to the cyclone 23, in which the temperature drops below, and from the lower part of the cyclone 23 goes to further processing, and the heat in the form of released steam goes to the heat exchanger 24,

    Claims (2)
    [1]
    Invention Formula
    J, A method of unloading defibrated wood, including defibrating the pressurized chamber in a gas-filled chamber by means of a rotating shredder placed in the chamber, suspending the defibrated wood into a mass, and unloading the mass into the defibrated wood, which, in order to increase efficiency, unload the wood in the form of a mass, it is carried out under pressure through a gate formed by a mass of defibrated wood in a tank for defibrated wood, where The shutter is controlled by discharging the mass.
    [2]
    2. The method according to claim 1, 1 and 2, and the fact that before feeding the mass of defibrating wood into the tank for defibrating wood, it is crushed.
