Description
Technical field
The utility model relates to a kind of Flying Dutchman.
Background technology
Existing Flying Dutchman comprises cylinder body and is connected to the end cap at cylinder body two ends, and end cap is provided with axle installing hole, and axle installing hole is built with the axle be connected with end cap, and axle is integral type structure.Mainly there is following shortcoming in the Flying Dutchman of said structure.One, because axle is integral type structure, bulky and weight is large, not only makes difficulty, but also there is the shortcoming of assembling difficulty; Two, during drying cylinder work, be connected with the high temperature and high pressure steam entered by axle in it, end cap will overcome the pressure of steam on the one hand, will overcome the axial elongated top pressure caused it because axle is heated on the other hand, therefore the bearing capacity of end cap is little, easily causes danger.Three, in drying cylinder work, drying cylinder inside can produce a large amount of condensed waters, and when running up, due to the effect of centrifugal force, condensed water forms ring-type cascade, and heat has to pass through this cascade and conducts heat, and therefore heat transfer efficiency is low.Four, in order to improve the intensity of end cap, existing ending cover thickness is comparatively large, waste material, and cause drying cylinder body weight large, required driving force is large; In addition, the heat in cylinder body can be scattered and disappeared in a large number by end cap, causes thermal loss large, wastes energy.
Utility model content
One of the technical problems to be solved in the utility model is for one of above-mentioned shortcoming, provides a kind of Flying Dutchman being convenient to assemble.
For solving the problems of the technologies described above, the utility model provides a kind of Flying Dutchman of following structure, comprise cylinder body and the end cap being connected to cylinder body two ends, described end cap is provided with axle installing hole, described axle installing hole is connected and the axle of hollow built with described end cap, the condensate drain of being discharged by axle inner chamber by condensed water is provided with in cylinder body, its design feature is two body structures that described axle is made up of fore side half axle and transmission side half axle, described fore side half axle comprises fore side half axle body and is connected to the fore side spindle nose of fore side half axle body outer end, fore side half axle body outer end is provided with the fore side end flange for being connected with end cap, the inner is provided with end flanges in fore side, described transmission side half axle comprises transmission side half axle body and is connected to the transmission side spindle nose of transmission side half axle body outer end, and transmission side half axle body outer end is provided with transmission side end flange for being connected with end cap, the inner is provided with end flanges in transmission side, in described transmission side, end flanges is all less than axle installing hole diameter with the diameter of end flanges in fore side and together with the two is bolted.
The Flying Dutchman of said structure, its axle is two body structures be made up of fore side half axle and transmission side half axle, and in end flanges and fore side, the diameter of end flanges is all less than axle installing hole diameter in transmission side, can install from the two ends of cylinder body during installation, insert in cylinder body by fore side half axle from one end of cylinder body, transmission side half axle is inserted in cylinder body from the other end of cylinder body, after fore side half axle and transmission side half axle and cylinder cap connect, then by bolt, end flanges in transmission side and end flanges in fore side are carried out being connected; Thus the utility model is compared with the integral type axle of prior art, and its assembling is easier.
Two of the technical problems to be solved in the utility model is for above-mentioned shortcoming two, provides the Flying Dutchman that a kind of end cap bearing capacity is large.
For solving the problems of the technologies described above, the basis of technique scheme has been done following improvement, the chamber segment length sum that namely described fore side half axle and transmission side half axle are positioned at inner chamber of cylinder block is less than the axial length of inner chamber of cylinder block.
The chamber segment length sum being positioned at inner chamber of cylinder block due to fore side half axle and transmission side half axle is less than the axial length of inner chamber of cylinder block.After fore side half axle has been connected with cylinder cap with transmission side half axle, gap can be produced between the two the inner, the bolt of end flanges in two can be fastenedly connected further, make gap shrinks, pretension is applied to two end cap, make two end cap occur inwardly elastic deformation to occur, like this, during drying cylinder work, the pressure that steam produces end cap and because axle is heated the elongated pressure on top surface that it is caused of axis just can offset above-mentioned pretension, thus make end cap can bear higher pressure.
Pad is provided with between end flanges in end flanges and fore side in described transmission side.Due to the existence of pad, the bolted connecting end flanges in two to a certain extent time, pad will tightly be clamped by the inner of fore side half axle and transmission side half axle, even if fastening bolt further, also can not produce and pulling is further produced to end cap, can prevent the pretension of end cap applying excessive like this.
Three of the technical problems to be solved in the utility model is for above-mentioned shortcoming three, provides the Flying Dutchman that a kind of heat transfer efficiency is high.
For solving the problems of the technologies described above, the improvement opportunity scheme made is as follows: namely described inboard wall of cylinder block is provided with many annular grooves arranged along its axially spaced-apart, such condensed water will be collected in annular groove, cascade can not be formed, ring muscle between high-temperature steam with adjacent annular groove directly contacts, and can improve heat transfer efficiency.
In order to fast the condensed water in annular groove be discharged, described condensate drain comprises multiple interval and to be periphery the collecting box in cylinder body, described collecting box is connected with multiple siphon pipe stretched in described annular groove, described collecting box is by discharge pipe line and axle inner space.
In order to improve the intensity of axle, described fore side half axle body and fore side spindle nose and transmission side half axle body and transmission side spindle nose are the integrative-structure by casting.
In order to improve the bearing capacity of cylinder body, described cylinder body is steel cylinder body, and described end cap is steel end cap, cylinder body and end cap is soldered is integrated.
Four of the technical problems to be solved in the utility model is for above-mentioned shortcoming four, provides the Flying Dutchman that the few intensity of a kind of end cap consumptive material is high and heat loss is little.
For solving the problems of the technologies described above made improvement opportunity scheme be: the outer face of described end cap is provided with the convex tendon of many evaginations; Fill insulant material layer in the depressed area formed between described convex tendon.Convex tendon the intensity that greatly can improve end cap is set, thus avoid end cap integral thickness thickening, be beneficial to saving material, and adiabator layer the loss that can prevent heat is set, be beneficial to economize energy.
As a kind of implementation of convex tendon, described convex tendon at least comprises the radial convex tendon that an annular convex rib arranged along described end cap outward flange and many radial directions along end cap extend.
In sum, the utility model has the advantage of: easily, end cap bearing capacity is large, consumptive material is few, intensity is high in axle assembling, and the pressure-bearing of cylinder body is large and heat transference efficiency is high, and thermal loss is little.
