    A sealing arrangement for a shutter for a feeding chamber of a continuously operating pressure grinder. The feeding chamber is provided with an inlet opening for feeding wood batches at atmospheric pressure into said feeding chamber and with an outlet opening for feeding said wood batches into the grinding chamber at overpressure. Each opening of said feeding chamber is provided with a shutter movable between an opened position and a closed position for preventing of escape of said overpressure through said feeding chamber. The feeding chamber is provided with a fixed guide supporting the shutter during its movement between opened and closed positions. Said guide comprises two parallel support surfaces between which the shutter is slidably mounted. The distance between said support surfaces is greater than the thickness of the shutter adjacent said support surfaces so that the shutter is displaceable towards and away from said support surfaces in a direction perpendicular to said support surfaces. A sealing element is provided in one of said support surfaces in such a way that, when the shutter is displaced away from said one support surface towards the other support surface, the shutter is released from contact with said sealing element. In this way the shutter is due to the pressure difference between opposite sides of the shutter pressed against said one support surface and against said sealing element but is released from contact with said support surface and said sealing element when the pressures are equilized on opposite sides of the shutter and can be moved to open and closed positions without said contact.

    This invention relates to a sealing device for shutting the loading chamber of a pressure defib ™ papa o.
    The aim of the invention is to simplify the construction and increase the hope of
    Fig. 1 shows a pressure finisher, a vertical section for phage, 2 a section where seals are located in the vertical section; Fig. 3 is the same, in a plane perpendicular to the plane of the flap.
    The pressure finisher contains a box of grinding stone 3 installed in the chamber and a grinding chamber 3 installed in the chamber of the inlet chamber 4j inlet 5 and inlet 6 windows located respectively in the upper and lower parts of the said inlet chamber containing a non-subframe (nun) guide for the flap-1SI 7 and formed by the top 8 and the nilotea 9 sealing support sightings mIa
    The upper surface has a sealing ™ element 10 located on the side of the flap for interacting with it 5 installed with an air movement interfacing mechanism; at the open and closed positions, the upper sealing surface of the bearing 8 is provided with a groove 11 in which sealing element 10 In the device, the flap 7 is installed with a gap in relation to the lower sealing support surface and is displaceable in a plane perpendicular to the plane of the flap. The device has a pressure generating means 12 installed on the side of the upper sealing surface Sj and a sealing element, which can have a tubular shape and be connected to a pressure generating means, performed in the form of a pipeline 12 with a three-line valve 13, is connected. with elements 14 of the compound in contact with a source of compressed air or liquid and, accordingly, with the atmosphere
    The upper sealing surface is provided with an additional groove 15 with an additional sealing ring 165 iqjH located therein and an additional groove.

    C1 is mounted next to the main groove 11, The device is equipped with spring-loaded steel brushes 17 5 in contact with the upper verticality of the flap and the flushing attachment 18.
    A three-way valve 13 is provided with an adjusting device 19, which is connected via pipe 20 to a sensing element 2IJ which, by means of pipelines 22, reacts to a pressure differential between the loading chamber 4 and the grinding chamber 2, where the material pushed by the pusher 23 mounted is movable under the loading chamber 4
    The device works as follows
     The wood bars that need to be crushed are dumped into the loading chamber 4 with the top flap open and the bottom flap closed, / 5 after which the top flap closes. The loading chamber supplies the pressure J corresponding to the excess pressure, for example i-3 bar, in the chamber. grinding. The flap is displaced from the lower sealing surface to the interaction with the upper sealing surface and with the sealing element placed in the latter, when a pressure period is created between the opposite side of the flap side, which causes the flap to move towards the upper bearing surface. If on both sides of the flap the same pressure is applied, then it is displaced to the lower bearing surface of the sealing surface, it goes out of the interaction with the seal: with this element and installed in the open position without interacting with the sealing element
    When the sealing element is made with a pressure medium, it can expand under pressure and extend beyond the sealing support surface or retract into the latter. After that, the bottom flap 5 is opened, as a result of which the bars, located in the loading chamber, flow into the grinding chamber. The process then repeats. The upper sealing surface, the reliability of the seal can be equipped with an additional sealing element 16; After the descent.
