Abstract

1. DEVICE DRYA DRYING OF FLOORING MATERIAL containing a drying element and means for creating a gas intermediate layer between the heated surface of the element and the turn facing it; {n> the processed material, characterized in that, in order to reduce the energy intensity of the process while simplifying the design of the device, means for ensuring the creation of a gas intermediate layer is installed in front of the drying element in the course of the processed material and contains a lubricant carrier placed with the possibility of contacting facing the dryer element. 2. Device According to 1, about 1 T. It is due to the fact that the lubricant carrier is a paraffin block with a length equal to the width of the drying element.

Description

The invention relates to equipment for drying linen-like material and can be used in the pulp and paper industry in the manufacture of coated and solid glued cardboard.

A device for drying linen-like material is known, comprising a drying table and means for transporting iio-Toina L.

The disadvantage of this system is the high energy intensity of the drying process, due to the need to overcome considerable resistance to the movement of the material web on the surface of the drying table, which consumes up to 30% of the power consumed for the production of corrugated cardboard as a whole on a corrugated board.

A device for sueshi poured / nano-shaped material is known, which contains a drying element and means for creating a gas intermediate layer between the heated surface of the element and the surface of the material 2 facing it.

The gas intermediate layer in the device is created by blowing air between the heated surface of the drying element - the table and the canvas of material being moved along it, for which special devices are introduced into the design of the drying table. Thus, additional power is expended on the creation of the gas layer, without compensating for the reduction in resistance to the movement of the web of material along the drying table. In addition, the presence of special devices for creating a gas layer complicates the design of the drying table.

The purpose of the invention is to reduce the energy intensity of the process while simplifying the design of the device.

The goal is achieved by the fact that in a device for drying linen-like material containing a drying element and means for creating a gas-intermediate layer between the heated surface of the element and the surface of the material being turned to it, means for providing a gas intermediate layer are installed in front of the drying element during the movement of the material being processed and contains a lubricant carrier placed with the possibility of contacting with

the side of the processed material facing the drying element.

The lubricant carrier is a bar

paraffin length equal to the width of the drying element.

FIG. 1 shows a drying device; FIG. 2 — node I in FIG. one .

The device includes successively installed roll 1 with a web roll for the cover layer, a heater 2, an adhesive applicator 3 for applying glue to the tops

corrugated double-layer fabric coming from the accumulation bridge (not shown) 5 and the drying element - table 4. Between roll 1 and heater 2, mounted on a stand is installed

5 a holder 6 of a bar 7 of a lubricant, for example paraffin interacting with the underside of the web, for a cover layer facing the drying table 4. The holder

6 is provided with a clamping element 8 and an adjusting device 9 interacting with the bar 7 of the lubricant.

A double-layer corrugated cardboard sheet from an accumulative bridge is fed to the gluing machine 3, where glue is applied to the tops of the corrugations of the canvas, followed by the fabric to the drying table. At the same time, a canvas that is connected to the canvas, unwound from roll 1 and preheated in heater 2 to cover layer on which from the bottom side is fed to the substantive table

Before serving, a layer of lubricant is applied to the preheater 2. Upon contact of the fabric with the surface of the drying table 4, having a temperature of 140 ° C, there is an intense

evaporation (up to boiling) of a lubricant (paraffin used as a lubricant has a T, W1. up to 70 C). Upon evaporation of the lubricant,

gas intermediate layer between the surface of the drying table A and the bottom side of the treated fabric.

The position of the lubricant bar 7 in the holder 6 during installation and abrasion during operation is controlled by the fixture 9, after which the bar 7 is fixed in the holder 6 by the clamping element 8. Creating an intermediate gas layer reduces the resistance of the processed material to the movement of the material to be dried on the surface of the drying table; on the surface of the drying table, the sticking of the cloth with the formation of so-called cigars on the surface of the drying table 1 92 is eliminated. practically no additional energy is expended in the new intermediate layer. The consumption of paraffin used as a lubricant in the process of work is insignificant: a bar with a cross section of 50–50 mm is enough to operate for 2 months. at three-shift work.
