Embodiment Construction
[0014] The sealing head 1 shown in the figure is used to convey a heat-carrying medium, especially a hot oil, to a rotating pressure system 2, such as a drying cylinder, heating roller, etc., which is only used in the figure Its connected devices are indicated. To this end, the sealing head 1 comprises: a tubular rotor 3 connected to the pressure system 2, and a stationary sealing head housing 5 arranged on the rotor 3 via two roller bearings 4, the sealing head housing 5 has a guide for a Connecting pipes 6 for the connecting pipes of the heat transfer medium, which are not shown in detail in the figures. Inside the sealing head housing 5 , the rotor 3 directly communicates with the connection pipe 6 via the orifice 7 on the open pipe end, so that the heat transfer medium can reach the pressure system through the connection pipe 6 and the rotor 3 . A rotary ring seal 8 is arranged axially between the connecting tube 6 and the rolling bearing 4 , which seals the rotor 3 again...

Sealed head of a drying drum, a heating roller or the like, is used to transfor a heat transfer medium, in particular hot oil, to a rotary pressure system, including: a tubular rotor connected with the pressure system and a moveless sealing head housing mounted on the rotor by a rolling bearing. The housing has at least a conncting tube for guiding the heat transfer medium to connect with the pipeline, wherein, the rotor is communicated with the connecting tube in the opening former in the sealing head housing, and provided with a rotary ring sealing piece along axial direction between the connecting tube and the rolling bearing for airproofing the wall of the sealing head housing by a rotor needle. The rotary ring sealing piece is suurounded by a cooling frange mounted on the sealing head housing, the cooling frange extending to the rotary ring sealing piece from both sides along axial direction. An insulated element is provided for airproofing the space between the rotor and the sealing head housing and the residuel narrow ring gap at one side where the rotary ring sealing piece is towards the connecting tube.
Description
technical field [0001] The present invention relates to a sealing head for conveying a heat-carrying medium, especially a heat-carrying oil, to a rotating pressure system, such as a drying cylinder, heating roller, etc., which comprises: a sealing head connected to the pressure system Tubular rotor and a stationary sealing head housing mounted on the rotor by means of grease or oil-lubricated roller bearings, the housing has at least one connecting pipe for a connecting line leading a heat transfer medium, wherein the sealing head housing Inside, the rotor is in open communication with the connecting pipe, and a rotary ring seal is arranged axially between the connecting pipe and the rolling bearing, sealing the rotor against the wall of the sealing head housing. Background technique [0002] Such sealing heads are disclosed, for example, in EP 0448730 and have proven to be particularly effective in practice. However, it should be noted that this solution requires high outl...
