Abstract

The utility model provides a continuous paper heating device. The continuous paper heating device comprises a pre-heater. The pre-heater comprises a cylindrical heat transmission wall and the outer surface of the heat transmission wall is a heating outer surface. The two end faces of the heat transmission wall are respectively provided with a high-pressure steam inlet, a low-voltage steam inlet and a condensing air return opening. A plurality of exhaust ports are further formed in the outer surface of the heat transmission wall. The continuous paper heating device has the advantages that through the mutual effect of high-pressure steam and low-pressure steam, a steam film can be formed at the positions of the exhaust ports of the paper heating device. The steam film can provide enough humidity for paper to enable fibers of the paper to become loose and soft and easy to roll, therefore, friction between the heating device and the outer surface of the paper is greatly reduced, and the paper is prevented from being torn and folded so that damage of the paper can be avoided.

Description

A kind of continuous form heater

Technical field

This practicality relates to the paper heating device using in a kind of paper production, the continuous form heater in especially a kind of single-side machine.

Background technology

Paper heating device in existing technology single-side machine, often can make paper be dried, be difficult for curling, and the friction existing between device for simultaneous heating and paper, usually can make paper time oppositely pull in motion, causes the breakage of paper.

Summary of the invention

Problem to be solved in the utility model is to provide a kind of friction that can obviously reduce between heater and paper outer surface, avoids paper to tear folding and damaged continuous form heater.

For solving the problems of the technologies described above, the technical solution adopted in the utility model is: comprise pre-heater, described pre-heater comprises the hot conductive walls of a cylinder barrel shaped, and the outer surface of described hot conductive walls is heating outer surface;

A high steam import, a low-pressure steam air inlet and a condensation gas returning port are respectively set on two end faces of described hot conductive walls; On the outer surface of described hot conductive walls, be also provided with several exhaust outlets.

Described high steam import is connected by the one-level pipeline being distributed in described hot conductive walls that wriggles with described condensation gas returning port.

Described low-pressure steam air inlet is connected by the secondary pipeline being distributed in described hot conductive walls with described exhaust outlet.

The setting of described condensation gas returning port, lower than described high steam import, is convenient to discharge condensing agent by gravity.

Advantage and the good effect that the utlity model has are: owing to adopting technique scheme, by the interaction of high-low pressure steam, make described paper heating device can form a steam blanket at steam vent place.This steam blanket can provide enough humidity to paper, makes the fiber of paper become loosening soft, more easily curling, has greatly reduced the friction between heater and paper outer surface, avoids paper to tear folding and damaged, and the while also can be improved the process speed of single-side machine equipment.

The specific embodiment

As shown in Figure 1, the utility model comprises pre-heater, and pre-heater comprises the hot conductive walls 1 of a cylinder barrel shaped, and the outer surface of hot conductive walls 1 is heating outer surface;

A high steam import 2, low-pressure steam air inlet 3 and a condensation gas returning port 4 are respectively set on two end faces of hot conductive walls 1; On the outer surface of described hot conductive walls 1, be also provided with several exhaust outlets 5.

High steam import 2 is connected by the one-level pipeline being distributed in hot conductive walls 1 that wriggles with condensation gas returning port 4.

Low-pressure steam air inlet 3 is connected by the secondary pipeline being distributed in hot conductive walls 1 with exhaust outlet 5.

The setting of condensation gas returning port 4, lower than high steam import 2, is convenient to discharge condensing agent by gravity.

The course of work of this example: the moist steam of high pressure enters by high steam import 2, pass wriggling in being distributed in the one-level pipeline in hot conductive walls 1, steam thermal energy,, emits by condensation gas returning port 4 after high steam release heat to outer surface releasing heat energy by hot conductive walls 1.

Low-pressure steam is entered by low-pressure steam air inlet 3, in secondary pipeline in being distributed in hot conductive walls 1, flow, from exhaust outlet 5, discharge, produce a steam blanket, this steam blanket is present between the outer surface and pre-heater of paper, steam blanket fully supports paper, and reduces the friction between paper and pre-heater.

High steam is unwell to paper and directly contacts, because high steam is as passed in secondary pipeline, can from exhaust outlet 5, discharge at a high speed, causes the contact failure with paper, so select to pass into low-pressure steam simultaneously.High steam in one-level pipeline is higher than the low-pressure steam temperature in secondary pipeline, and heat is delivered to secondary pipeline through overheated conductive walls from one-level pipeline, and low-pressure steam is heated up, and is used to form steam blanket.

Above an embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to for limiting practical range of the present utility model.All equalization variations of doing according to the utility model application range and improvement etc., within all should still belonging to patent covering scope of the present utility model.
