Description
Technical field
This utility model relates to paper production equipment technical field, is specifically related to a kind of for the production of resistance to water hanging raw stock
Drying cylinder when being dried.
Background technology
Drying cylinder, for paper machine, need to have good pressure-bearing and heat transfer effect.When the rotary speed of drying cylinder is the highest
Or time static, the condensed water in cylinder under gravity, always falls in drying cylinder bottom, can be by the drainage arrangement fixed by condensed water
Discharge, but when drying cylinder rotating speed reaches certain value, due to the effect of centrifugal force, condensed water forms a water ring in drying cylinder, this
The steam of Shi Jiare, by condensation, transfers heat on water ring, then by water ring, heat is delivered to drying cylinder cylinder
Wall, is eventually transferred into the l Water Paper pulp layer of drying cylinder outer wall.How to improve the heat transfer efficiency of drying cylinder, the most more effectively process in drying cylinder
Condensed water become those skilled in the art's technical problem to be solved.
Utility model content
Therefore, for the problems referred to above, this utility model provides that a kind of heat transfer efficiency is high, be easy to condensed water discharge for resistance to
Aqueous hanging raw stock produces drying cylinder when being dried.
For reaching above-mentioned purpose, this utility model is achieved through the following technical solutions:
A kind of drying cylinder when resistance to water hanging raw stock produces dry, including cylinder body, the both sides free end of described cylinder body
On be respectively equipped with end cap, the central hole of two end cap is connected to cylinder shaft, the free end coaxial sleeve of two end cap be provided with insulation pressure
Lid, the inner surface of described cylinder body is welded and fixed a spiral helicine rib, described rib uniformly offers a plurality of for cold
The through hole that solidifying current are logical, the periphery of described end cap the inner is provided with a water leg, and described water leg connects a drainage arrangement.
Preferably, described drainage arrangement includes that suction head, siphon, described suction head are arranged in described water leg, institute
Stating siphon one end and stretch out described end cap, the other end is connected with described suction head.
Preferably, being provided with heat insulation layer between described end cap and insulation gland, described heat insulation layer includes layer successively
Folded asbestos layer and heat insulation aluminium layers of foil.
Preferably, described through hole is angularly disposed.
By using preceding solution, the beneficial effects of the utility model are: by arranging helical structure in drying cylinder
Rib, and on rib, offer through hole, make drying cylinder form spiral water ring when running, and by through hole increase internal rib it
Between the circulation of condensed water, and then make water ring integral thinned, steam carries out heat transfer by relatively thin water ring and rib, more favorably
In the transmission of heat, improve heat transference efficiency, simultaneously because of the spiral type rib arranged, condensed water is concentrated on the end cap of one end
Water leg in, it is only necessary to drainage arrangement is set in water leg, can more concentrate, advantageously condensed water be discharged outside drying cylinder.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment.
Detailed description of the invention
Embodiment of the present utility model is described in detail, whereby to this utility model such as below with reference to specific embodiment
What application technology means solves technical problem, and the process that realizes reaching technique effect can fully understand and implement according to this.
Reference Fig. 1, a kind of drying cylinder when resistance to water hanging raw stock produces dry, including cylinder body 1, described cylinder body 1
Being respectively equipped with end cap 2 on the free end of both sides, the central hole of two end cap 2 is connected to cylinder shaft 3, and the free end of two end cap 2 is same
Axle sleeve is provided with insulation gland 4, is provided with heat insulation layer 5 between end cap 2 and insulation gland 4, and described heat insulation layer 5 includes successively
The asbestos layer 51 of stacking and heat insulation aluminium layers of foil 52, can effectively prevent that heat losses in cylinder body, the thermal efficiency are high, be greatly saved energy
Source；It is welded and fixed a spiral helicine rib 11 on the inner surface of described cylinder body 1, described rib 11 uniformly offers a plurality of use
In the through hole 12 of condensed water circulation, in the present embodiment, when offering through hole 12, by angularly disposed for described through hole 12, more conducively rib
Condensed water circulation between 11, improves flowing velocity, and then improves heat transfer efficiency；The periphery of described end cap 2 the inner is provided with
One water leg 21, described water leg 21 connects a drainage arrangement, and described drainage arrangement includes suction head 61, siphon 62, described
Suction head 61 is arranged in described water leg 21, and described end cap 2, the other end and described suction head are stretched out in described siphon 62 one end
61 connect, and suction head 61 set in the present embodiment is funnel-form, can preferably inhale and draw condensed water, promote draining.
This utility model is by arranging the rib of helical structure in drying cylinder, and offers through hole on rib, makes drying cylinder exist
Form spiral water ring during running, and increased the circulation of condensed water between internal rib by through hole, and then make water ring integral thinned,
Steam carries out heat transfer by relatively thin water ring and rib, is more beneficial for the transmission of heat, improves heat transference efficiency, simultaneously because of
The spiral type rib arranged, is concentrated to condensed water in the water leg on the end cap of one end, it is only necessary to arrange draining in water leg
Device, can more concentrate, advantageously be discharged outside drying cylinder by condensed water.
Although specifically show and describe this utility model in conjunction with preferred embodiment, but those skilled in the art should
This is understood, in the spirit and scope of the present utility model limited without departing from appended claims, in form and details
On this utility model can be made a variety of changes, be protection domain of the present utility model.
