Description
Technical field
The present invention relates to the drying equipment of a kind of the drying material breadth that is used for, especially paper web face, paper/paper sheet breadth or tissue paper breadth.This drying equipment comprises can steam-heated cylinder, and this cylinder has an inner space with shell face and one and is used to improve the equipment that transmit to the heat on the shell face in space internally.That this equipment comprises is axial arranged, have and disturb lath with at least one of the contacted contact-making surface of shell face and be used for disturbing lath to be pressed onto at least one extrusion element on the shell face at least one.
Background technology
The known cylinder that has this equipment.Therefore, in patent documentation EP1362951, put down in writing this equipment.Disturbing lath is that the pipe of rectangle constitutes by cross section, and is pressed onto on the inner wall of rotary drum through retaining ring.For with the fixing lath that disturbs of retaining ring, in disturbing lath, there is the perforation that is used to hold pin, said pin is threaded with retaining ring again or is connected by adapting device.
In other known solution, disturb lath directly to be connected with drum sleeve.Therefore, patent documentation DE2903784 is open, disturbs lath to be threaded with drum sleeve or is fixed on the drum sleeve by the servicing unit of tightening hoop and magnetic.
The shortcoming of embodiment of the prior art is that it is very expensive to make the jockey that disturbs lath and drum sleeve, needs very long manufacturing and installation time in addition.
Summary of the invention
Technical problem to be solved by this invention is, improves known drying equipment, makes it implement cheap, reliable and practical.
This technical problem solves through the characteristic of claim 1.At this to the present invention importantly, the contact-making surface of shell face and/or interference lath has the device that is used to improve the shell face and disturbs coefficient of friction between the lath.
Thus, each lath cage module of disturbing lath also therefore to be made up of a plurality of interference laths and a plurality of retaining ring that has tension element in addition is fixed in the drum space reliably.Can in cylinder, vertically one after the other arrange a plurality of lath cage modules in front and back along cylinder.Another advantage by solution of the present invention is to avoid being used for fixing in the drum sleeve to disturb lath also therefore to weaken the perforation or the screwed hole of drum sleeve.In addition, can more cheap, simply and easily fix and install the interference lath.Though cylinder long in addition possibly reach the maintenance intervals in 1 year during have strong variations in temperature, can prevent to disturb the lath landing equally by solution of the present invention.
As a kind of feasible organization plan of the present invention, the surface texture of shell face and/or the contact-making surface of interference lath are designed for the device that improves coefficient of friction.Such advantage is though disturb lath to compress through retaining ring moderately, to guarantee quite reliable and lasting fixing.
The shell face preferably only has surface texture in having the contact area that disturbs lath.
In a kind of utility structure scheme, surface texture has rill.
Rill can be along roll circumference direction and/or extending axially along relative cylinder axis.
In another kind of design variant, rill can along depart from drum shaft to direction extend.
Same feasible is to disturb the contact-making surface of lath to have some zones that have different surface structure and/or orientation various structure.Through using different surface structure 7 and various structure orientation, can realize disturbing lath 2 to overcome secure fixation from the power of all directions.
In a kind of feasible form of implementation, disturb the contact-making surface of lath to have some zones that only partly have surface texture.
In a kind of suitable organization plan of the present invention, disturb the surface of the whole sensing shell face of lath to form contact-making surface.
In another kind of organization plan, the only part on the surface of the sensing shell face of interference lath forms contact-making surface.
In a kind of design of practicality, rill is designed to sharp-pointed profile of tooth.
Aptly, scabble in the scope of width between 0.01mm and 5mm at the tip of sharp-pointed profile of tooth, in the mm of 0.2mm to 0.5 scope, especially is 0.3mm preferably.
In a kind of preferred design variant, the average tooth depth or the average rill degree of depth or the average structure degree of depth be greater than 0.03mm, especially greater than 0.05mm, is preferably greater than or equals 0.1mm.Realize enough fixing thus.Mean value is equivalent to the arithmetic mean of instantaneous value of each degree of depth.
The material of cylinder belongs to class of metal materials aptly, for example grey cast-iron, cast steel or steel.The interference lath equally can be by metal material, and for example steel and high-quality steel are formed.
Feasible in addition is, surface texture is through removing the technology of smear metal, for example milling, grinding or through corrosion or etch or coating generation.
By the expansion design regulation of another kind of practicality, device is by forming material shell face and contact-making surface, that increase friction to forming.
In a kind of feasible practicality embodiment, can use following material right: metal/metal, metal/plastic, wherein, the heat resistance of used plastics especially more than or equal to 220 ° of C, is preferably greater than 250 ° of C greater than 200 ° of C.Can use the composite of carbon fiber reinforcement or contain thioplast as plastics.
In a kind of suitable organization plan, shell face and/or contact-making surface have coating.In a kind of feasible embodiment, coating material can be from adhesive field.
In addition, can stipulate that the material that constitutes shell face and contact-making surface has different hardness and/or different moduli of elasticity.
In the form of implementation of another kind of practicality; The interference lath is made up of channel section and two legs form contact-making surface; Wherein, retaining ring that extrusion element is along the circumferential direction extended by at least one, that have tension element is formed, wherein; The such acting in conjunction of this retaining ring and tension element, make to produce at least one retaining ring radially, affact the tension force that disturbs on the lath.
Disturb lath to be designed to, as known from prior art, channel section, quadrangle section or polygon section or open section or be designed to solid section.
Another aspect of the present invention relates to a kind of method that is used for fixing the equipment that the heat of raising in can the inner space with shell face of steam-heated cylinder transmits; Wherein, this equipment comprise axial arranged, have and disturb lath with at least one of the contacted contact-making surface of shell face and be used for disturbing lath to be pressed onto at least one extrusion element on the shell face.The characteristics of this method are, before fixing step, on shell face and/or contact-making surface, take to increase the measure of friction, like especially structuring or coating.
