Abstract

The utility model discloses an energy-saving heating device of a paper web, comprising a drying cylinder, a paper winding drum and a heating plate, wherein the paper web processed by the drying cylinder is wound on the paper winding drum; the heating plate is arranged below the paper web; the surface of the heating plate is arranged along the moving direction of the paper web and adhered to the lower surface of the paper web; the heating plate is internally provided with a heating passage; the condensate water in the drying cylinder serves as the heat source of the heating passage in the heating plate; and one end of the heating passage is communicated with the condensate water in the drying cylinder through a water pipe while the other end thereof is discharged outwards through the water pipe. By utilizing the condensate water of 80-90 degrees in the drying cylinder as the heat source for reheating the heating plate, the energy-saving heating device of the paper web can save energy, improve the surface performance of the paper and reduce the bound water content of the paper.

Description

The paper web energy-saving heating apparatus

Technical field

The utility model discloses a kind of paper web energy-saving heating apparatus, divide by International Patent Classification (IPC) (IPC) and to belong to the auxiliary heating of paper machine dryer parts manufacturing technology field, especially relate to the heating, drying device that a kind of paper web is got rid of the paper bound water after through the drying cylinder operation once more.

Background technology

Key steps such as modern papermaking program can be divided into slurrying, modulates, manufactures paper with pulp, processing, oven dry are one of the important operations in the step of manufacturing paper with pulp, and generally are to allow l Water Paper make the paper drying through the drum surface of drying cylinder, by reel machine paper web are rolled into paper roll then.But behind the existing drying cylinder baking operation, the bound water content of paper is still higher, influences its surface property, and the moisture content that contains through paper behind the drying cylinder comes together in the cylinder body, forms the condensed water that water temperature reaches the 80-90 degree, directly drains and has wasted heat beyond doubt.

The inventor utilizes the condensed water in the drying cylinder to create a novel paper web heating arrangements for thermal source, with further minimizing paper bound water content, so just the utility model proposes.

The utility model content

At the deficiency of existing paper web drying technology, the utility model provides a kind of paper web energy-saving heating apparatus of rational in infrastructure, environmental protection.

For achieving the above object, the utility model is achieved through the following technical solutions:

A kind of paper web energy-saving heating apparatus comprises drying cylinder, chart drum and heating plate, and the paper web that drying cylinder is handled is wound on the chart drum, and heating plate is arranged at the below of paper web, and the heating plate face is along the setting of paper web traffic direction and be close to the lower surface of paper web.

Further, be provided with in the described heating plate and add hot flow path, condensed water adds hot flow path one end and is communicated with condensed water in the drying cylinder by water pipe as the thermal source of heating plate internal heated runner in the drying cylinder, and other holds and discharges by water pipe to add hot flow path.

The condensed water that the utility model utilizes drying cylinder 80-90 degree is as the thermal source of heating plate once more, arranges to boiler dailyly after heating plate uses again, has following useful effect:

1, the utility model makes the paper web of drying cylinder processing more dried;

2, because thermal source adopts the condensed water of drying cylinder, has energy-conservation effect;

3, the utility model can improve the paper surface property and reduce paper bound water content;

4, accelerate the slaking of AKD glue, for next process improves yield rate.

6, water pipe.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing:

Embodiment: see also Fig. 1, a kind of paper web energy-saving heating apparatus comprises drying cylinder 1, chart drum 3 and heating plate 4, and the paper web 5 that drying cylinder 1 is handled is wound on the chart drum 3, heating plate 4 is arranged at the below of paper web 5, and the heating plate face is along the setting of paper web traffic direction and be close to the lower surface of paper web.

See also Fig. 2, be provided with in the described heating plate 4 and add hot flow path, condensed water 2 adds hot flow path one end and is communicated with condensed water in the drying cylinder by water pipe 6 as the thermal source of heating plate internal heated runner in the drying cylinder 1, and other holds and discharges by water pipe to add hot flow path.

The condensed water that the utility model utilizes drying cylinder 80-90 degree is as the thermal source of heating plate once more, arranges to boiler dailyly after heating plate uses again, has more dried, the energy-conservation effect of paper web that drying cylinder is handled; The utility model can improve the paper surface property and reduce paper bound water content; Accelerate the slaking of AKD glue, for next process improves yield rate.

The above record only for utilizing the embodiment of this origination techniques content, anyly is familiar with modification, the variation that this skill person uses this creation to do, and all belongs to the claim of this creation opinion, and is not limited to those disclosed embodiments.

Claims
