Description
Technical field
The present invention relates to a kind of drying cylinder end cover, more particularly, to a kind of insulation end cover of drying cylinder.
Background technology
The equipment that paper industry is used for dry paper is typically drying cylinder.Steam or other heating agents are passed through in drying cylinder, passes through cylinder
Wall conducts heat, with the paper of high temperature drying drying cylinder cylinder outer wall.But the end cap face of drying cylinder is not working face, passes through radiant heat transfer and sky
Gas convection current wastes substantial amounts of heat.Through researching and analysing, when the end cap of drying cylinder does not take Insulation, the heat of waste accounts for
The 8%~11% of total heat supply, therefore heat insulation measure is taken to the end cap of drying cylinder, for reducing energy consumption, increase economic efficiency
There is great meaning.Drying cylinder end cover without heat insulation measure simultaneously, because there is very high temperature, easily causes human body to scald
Wound, the also personal safety to operator bring threat.Therefore drying cylinder end cover is taken heat insulation measure turn into drying cylinder or
The necessary technology of similar product.
Chinese patent CN2149417 discloses one kind《Thermal insulation end cover for paper-making dryer》, the utility model is in the close of drying cylinder
Complex material heat preservation layer is provided between end-blocking lid and backplate, is connected end cover, complex material heat preservation layer and backplate with bolt
Connect fixed composition insulation end cover of drying cylinder.But the technology pre- subdrilling many must be fixedly connected with bolt hole, drop on drying cylinder end cover
The low intensity of drying cylinder end cover.For having come into operation, but the drying cylinder of heat insulation measure is not taken, can not take necessary
Subsequent technology measure.
The convenience for also having technology to take into account insulation end cover making in addition, prefabricated component is fabricated to using insulation end cover,
Then splicing installation is carried out on end cap.But the technology is in order to ensure the close fitting of insulation material and drying cylinder end cover, equally
The auger shell keyhole on drying cylinder end cover is employed, insulation material is fixed by the turnbuckle being screwed on drying cylinder end cover.Because tense
Bolt hole so must have heavy duty machine tools to process, and must be wasted time and energy, extremely not in drying cylinder bulk heat treatmet post-processing
Just.And turnbuckle hole number is numerous, it is necessary to and the complete face of prefabricated mounting hole of prefabricated component, this just brings larger when mounted
Inconvenience, so as to greatly reduce prefabricated effectiveness.
