Abstract
The invention discloses a normal-pressure multichannel papermaking drying cylinder which comprises a cylinder body. The drying cylinder is characterized in that a plurality of heat conducting channels which are uniformly distributed are laterally or longitudinally arranged in the cylindrical cylinder wall of the cylinder body; one end of each heat conducting channel is communicated with a steam input pipe, and the other end is communicated with a condensed water output pipe; and the steam input pipe and the condensed water output pipe are respectively communicated with a steam inlet and a condensed water outlet of a rotary joint. When steam enters the heat conducting channels of the cylinder body of the drying cylinder with the structure, the cylindrical cylinder wall of the cylinder body emits heat, heat is transferred to wet paper to be dried on the surface of the cylinder wall, and the wet paper is heated and water evaporates, so that the purpose of drying is achieved. As the drying cylinder body adopts an open structure, and pressure only exists in the heat conducting channels, the drying cylinder body does not belong to a pressure container. The drying cylinder belongs to a normal-pressure drying cylinder, has a simple structure, is high in temperature and heat transfer efficiency, low in weight, smooth in steam flowing and condensed water discharging, and low in manufacture cost.
Description
Technical field
The present invention relates to a kind of drying equipment, especially the paper drying cylinder in the papermaking facility.
Background technology
In at present general papermaking facility, drying section is the main power consumption part of paper machine, and drying cylinder is the major part of Dryer Section of Paper Machine.Existing drying cylinder is mainly constructed and is comprised cylinder body, power transmission shaft, steam and condensed water turnover swivel joint, condensed water discharge siphon pipe and attemperator etc.The main task of drying cylinder is with the l Water Paper page oven dry through cylinder surfaces.The drying cylinder of this structure is in the process with the oven dry of l Water Paper page, ubiquity impeded drainage problem, build up in drying cylinder if in drying cylinder, the condensed water eliminating is bad, when gathering, the higher condensed water of rotating speed forms the condensation water ring when more, because condensation water ring thermal conductivity factor is low, to greatly increase the thermal resistance of drying cylinder, cause the drying efficiency of drying cylinder to descend; When the drying cylinder internal water accumulation, also can greatly increase the power that transmission consumes; When condensed water is discharged not freely off and on, can cause drying section electric load strenuous exercise, the mass dryness fraction of page is unstable, affects the normal operation of paper machine; The transmission balance of drying cylinder is destroyed, thereby caused paper machine running mid frame to produce vibration.Siphon pipe is mainly used to get rid of the drying cylinder condensed water at present, but when the rotating speed requirement was high, the drying cylinder condensed water was got rid of or be undesirable.In addition, existing drying cylinder belongs to airtight pressure vessel, and casing wall and end cap need enough wall thickness to bear steam pressure.Steam pressure is higher, and the casing wall wall thickness is larger, and resistance to heat is also larger, thereby the production capacity raising of drying cylinder is restricted, and the material such as drying cylinder weight and consumption steel increases simultaneously.In order to overcome the shortcoming of traditional drying cylinder, also someone proposes multichannel drying cylinder theory and studies at present, and the major programme of proposition has: 1, at drying cylinder inwall casting groove, and cover cover plate on groove; 2, at drying cylinder outer wall casting groove, and cover cover plate on groove; 3, at the drying cylinder inwall, metal corrugated plate is installed.These schemes still can't realize using because of reasons such as difficulty of processing, stressed, sealings so far.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, heat transfer efficiency is high, condensate water discharging is unimpeded, temperature is high and cost is low normal pressure multichannel paper-making drying cylinder.
For reaching above-mentioned purpose, technical scheme of the present invention is:
A kind of normal pressure multichannel paper-making drying cylinder, it comprises cylinder body, it is characterized in that:
In the tubular casing wall of the garden of described cylinder body, laterally or vertically be provided with uniform some passages of heat;
One end of described each passage of heat is connected with steam input pipe, and the other end is communicated with condensate output transistor;
Described steam input pipe, condensate output transistor are communicated with steam inlet and the condensation-water drain of swivel joint respectively.
Described each passage of heat is divided into some groups, and the two ends of every group are communicated with respectively with steam inlet and condensation-water drain respectively.
The drying cylinder of said structure, casing wall is connected with the wheel hub at two ends, and the two ends spoke is separately fixed on the power transmission shaft of both sides, is fixedly connected with swivel joint in an end axle wherein.Vapours is redistributed in the passage of heat of cylinder body from the steam inlet of swivel joint to steam input pipe.Steam enters the passage of heat of cylinder body, makes the garden tubular casing wall heating of cylinder body, and heat passes on the casing wall surface and needs the dry wet paper, the wet paper moisture content that evaporates by heat, thus reach dry purpose.When steam was to the wet paper drying, steam was condensed into water, and the Steam Actuation that is constantly entered in passage of heat, shifted condensed water onto condensation-water drain, discharged from the condensation-water drain of swivel joint at last.Because the drying cylinder structure is opened wide, because passage of heat is less, can bear higher pressure, and only pressure be arranged in passage of heat, so drying cylinder does not belong to pressure vessel.Therefore, drying cylinder of the present invention is a kind of non-pressure vessel, and is simple in structure, and heat transfer efficiency is high, and temperature is high, and is lightweight, the paper drying equipment of the unimpeded and low cost of manufacture of vapor flow and condensate water discharging.
