Device for removing liquid from inside a rotating cylinder -Anordning för avlägsning av vätska frän en roterande cylinder

The invention relates to a device for advantageously adjusting condensate or water injected inside a rotating cylinder with a preferred purge gas / liquid ratio.

10 The disadvantage of the correspondingly operating devices in use has been that, when the amount condensed in the cylinder varies, the outlet pipes must be dimensioned according to the maximum amount of liquid to be removed. The essential features of the invention are set out in the appended claims. The device according to the invention can also be used to adjust the thickness of the liquid layer from outside the cylinder. The disadvantages of the current devices can be completely eliminated by the device and method according to the invention. This results in an economical and easy to run process.

Figure 1 shows the principle of the invention. From the inside of the cylinder 4, the liquid is led out by means of a nozzle 1 along an outlet pipe or pipes 2 which are or are assembled from two or more lines. The outlet pipe consists of a radial part 2 and a part 3 parallel to the axis 5 of the cylinder.

The axial part 3 extends inside the shaft out of the cylinder-30 blades to the steam and condensate switch. According to the invention, the necessary outlet pipe or pipes can simply be closed or opened via the rear cover 7 of the condenser switch.

Since the amount of purge gas depends substantially on the available surface area of the exhaust pipe 35, in addition to the pressure difference, the liquid / gas volume ratio can be adjusted advantageously taking into account the amount of liquid to be removed.

With the device according to the invention, it is very simple to select the thickness of the liquid layer inside the cylinder from outside the cylinder. Drainage nozzles at different distances 5 from the inner surface of the cylinder are pre-positioned or made in the dewatering nozzle 1. If it is desired to change the thickness of the liquid layer, a gap for removing a suitable liquid height can be selected via the back cover of the condenser switch. This area of the invention is of great importance, for example, in improving the heat transfer of high-speed paper machines.

10 For this purpose, a so-called spoiler bars. The operating efficiency of the heating strip depends on the thickness of the condensate layer. According to the invention, this layer thickness can be adjusted from outside the machine cylinder.
