SU1532630A1 - Drying table of corrugating unit - Google Patents

Abstract

The invention relates to devices for drying linen-like material and can be used in the pulp and paper industry as a part of lines for the production of corrugated paperboard. The purpose of the invention is to improve the quality of the web due to the possibility of controlling the heat flux in width. The drying table of the corrugating unit includes heating plates 1 with working surfaces 2, installed with a gap 3 relative to each other in series in the direction of the web. Between the rows of heating plates 1 of the drying table in the gaps 4, plates 5 are installed, equipped with heaters and oriented in the direction of web movement. The working surfaces of the plates 5 are located at the level of the working surfaces 2 of the heating plates 1. The heaters are mounted under the plates 5 and can be equipped with reflective screens hinged under them. The heating plates 1 are autonomously heated using a coolant supply system 9 and removal of the spent heat carrier system 10. 1 hp f-ly, 2 ill.

Description

5 are located at the level of the working surfaces 2 of the heating plates 1. The heaters are mounted under the plates 5 and can be equipped with reflective screens hinged under them. The heating plates 1 are autonomously heated using the system 9 for supplying the heat transfer medium and the drainage system 10 for the spent heat transfer medium. 1 hp f-ly, 2 ill.

The invention relates to a device, 1M for drying linen-like material and can be used in the pulp and paper industry and its composition is a line for the production of corrugated cardboard.

The purpose of the invention is to improve the quality of the web by allowing the heat flow to be regulated along its width.

Pa figs. 1 shows a drying table for a corrugating unit; in fig. 2 is a section A-A in FIG. one.

The drying cabinet of the corrugating unit includes heating plates 1 with working surfaces 2, installed with a gap 3 one relative to the other in series in the direction of the web. Between the rows of heating plates 1 of the drying table, in the gaps 4, plates 5 are installed, equipped with heaters 6 and oriented in the direction of web movement. The working surfaces 7 of the plates 5 are located at the level of the working surfaces 2 of the heating plates 1. Heaters 6 are mounted under the plates 5 and can be equipped with hinges with reflective screens 8 fixed under them. The heating plates I are autonomously heated using a system 9, 10 heat carrier supply and exhaust heat carrier.

The heating plates 1 are installed with the necessary differential due to their autonomous heating due to the gaps 3 that prevent their heat exchange.

The temperature of the plates 5 is established by the transition between the temperatures of adjacent rows of heating plates 1 by controlling the heating of the heaters 6. This creates a smooth temperature difference across the width of the drying table, which is necessary for high-quality drying of corrugated cardboard.

Claims (2)
