Definitions

  • the invention relates to a sealing head for supplying a heat transfer medium, esp. A heat transfer oil, to a rotating pressure system, such as a drying drum, heat roller or the like.
  • a sealing head for supplying a heat transfer medium, esp. A heat transfer oil
  • a rotating pressure system such as a drying drum, heat roller or the like.
  • Such a sealing head is known, for example, from EP 0 448 730 and has proven extremely successful in practice (see also document DE-C-196 18 661). It should be noted, however, that this solution requires increased expense because of the circulation of a master medium.
  • the invention has for its object to improve by constructive development of a sealing head of the type mentioned so that in a simplified structure nevertheless operation at maximum temperature of the heat transfer medium is made possible without increased wear occurs especially in the sealing area.
  • the mechanical seal is surrounded by a sealing head housing arranged on the cooling flange, which extends axially on both sides of the mechanical seal, and that on the connecting piece facing side of the mechanical seal a space between the rotor and the sealing head housing up on a remaining narrow annular gap sealing insulating is provided.
  • the advantage achieved by the invention consists essentially in the fact that despite reduced expenses, such as the implementation of simple cooling measures and the attachment of a simple insulating safe operation at maximum temperature of the heat transfer medium is possible without standstill problems occur at the seal.
  • the insulating element is expediently designed as a sealing head housing fixed sleeve part, wherein the connecting piece facing side is formed as a radially projecting inner flange, whose lateral surface forms the boundary of the annular gap as a boundary to the engine. In this way, a clear thermal insulation is first achieved to the connection piece out.
  • the insulating member is supported axially against the cooling flange, since thus a seamless insulation is achieved to the cooling flange.
  • the insulating element consists of a material of low thermal conductivity.
  • the cooling flange has an annular cooling chamber for a flowing cooling medium.
  • the cooling chamber is provided with a respective diametrically arranged inlet and outlet. This ensures a complete separation of this cooling circuit, so that the cooling can be done either with lubricating oil or only with cooling water.
  • a closed chamber forming sealing element is arranged, wherein in the chamber a filling nozzle for a preferably liquid medium opens.
  • This chamber can be filled with a suitable liquid without pressure via the filling nozzle, whereby a chemical reaction between the oxygen in the air and over the mechanical seal leaking oil leakage is prevented.
  • the sealing head 1 shown in the drawing is used for supplying a heat transfer medium, in particular a heat transfer oil, to a rotating printing system 2, for example a drying drum, heat roller or the like, which is indicated in the drawing only with its connecting device.
  • the sealing head 1 consists of a connected to the pressure system 2 tubular rotor 3 and a two roller bearings 4 arranged on the rotor 3 stationary sealing head housing 5, which has a connection piece 6 for a heat transfer medium leading, not shown in the drawing connection line.
  • the rotor 3 is at the open end of the tube via openings 7 in direct communication with the Connecting piece 6, so that the heat transfer medium can pass through the connecting piece 6 and the rotor 3 in the printing system.
  • a mechanical seal 8 is arranged, which seals the rotor 3 against the wall of the sealing head housing 5.
  • This mechanical seal 8 is preferably made of a sealing ring 10 secured to the rotor 3 via a bellows 9 and a sealing ring 11 fixedly arranged on the sealing head housing 5.
  • the mechanical seal 8 is enclosed by a cooling flange 12 arranged on the sealing head housing 5, which extends axially on both sides to the mechanical seal 8.
  • the insulating member 14 is designed in detail as fixed to the sealing head housing 5 sleeve part, wherein the connecting piece 6 facing side is formed as a radially projecting inner flange.
  • the inner circumferential surface of this inner flange forms the boundary of the annular gap 13 towards the rotor 3.
  • the axial height of this inner flange affects the width of the annular gap 13, whereby the circulation of heat transfer medium between the outer region of the mechanical seal 8 and the area flowed through at the connecting piece 6 and the openings 7 largely prevented and thus the temperature of the Heat transfer medium in the sealing area is significantly reduced.
  • the insulating member 14 is supported axially against the cooling flange 12, so that, since the insulating member 14 is suitably made of a material of low thermal conductivity, a continuous heat-insulating effect is achieved up to the cooling flange 12.
  • the cooling flange 12 has, as can be seen in particular from Figure 2, an annular cooling chamber 15, which is flowed through by a cooling medium.
  • the cooling chamber 15 is provided with a respective diametrically arranged inlet and outlet 16,17.
  • a cooling medium a variety of suitable liquids can be used, since this cooling circuit is self-contained, so no contact can occur, for example, with the heat transfer medium.
  • lubricating oil or even simple cooling water will be used for this purpose.
  • a closed chamber 18 forming sealing element 19 is disposed between the sealing head housing 5 and the rotor 3.
  • This thus formed chamber 18 can be filled via a filling nozzle 20 with a preferably liquid medium, thereby preventing that a chemical reaction of reaching over the mechanical seal 8 in this chamber 18 oil leakage can occur with atmospheric oxygen.
  • the rotor 3 is in the over the mechanical seal 8 and the sealing member 19 and the bearing 4 extending, provided with the reference numeral 21 area formed double-walled, which in addition the heat transfer from the rotor 3 ago to the mechanical seal 8 is reduced.
