Abstract
The utility model discloses a double-layer cold water roller, and belongs to the technical field of paper manufacturing. The double-layer cold water roller comprises an outer roller body and a liner arranged inside the outer roller body; the liner is connected with an end axle through a flange and is provided with a spiral piece, and the flange is provided with a water outlet hole; a flow channel is arranged inside the end axle; one end of the flow channel is connected with a water inlet of the liner, and the other end of the flow channel is connected with a cooling water inlet. Cooling water of the cooling water roller flows between the liner and the outer roller body, the spiral piece is arranged on the liner, and therefore heat exchanging time of the cooling water in the cooling water roller is prolonged, the amount of used cooling water is reduced, and cooling effect is more even.
Description
Technical field
The utility model relates to the paper making equipment field, is specifically related to for the dancing roll before the coating of high speed wide cut paper machine.
Background technology
Common coating machine adopts common paper injection to advance coating machine, and the page coating adhesion after coating is bad, easily fluffing.Now adopt cold water roller, the quality of improving coated paper is improved a lot, but in existing cold water roller use procedure, cooling water consumption is large, power consumption is many, and cost is higher.Cold water roller to the paper cooling procedure in, easily occur inhomogeneous cooling with, cause paper smoothness to reduce.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
The utility model content
The purpose of this utility model is to provide and a kind ofly can reduces cooling water and consumption of electric energy, reduces costs, and makes the cooling uniform cold water roller of paper.
For reaching above-mentioned purpose, the technical scheme that the utility model adopts is: invent a kind of double-deck cold water roller, comprise outer roll body and inner bag, inner bag is arranged on outer roll body inside.Inner bag is provided with flight, and is connected by flange with the end axle, and flange is provided with apopore; End axle inside is provided with runner; One end of runner is connected with the inner bag water inlet, and the other end is connected with cooling water inlet.
Preferably, apopore with go out bucket and be connected.
Preferably, going out bucket is fixed on bearing block.
Preferably, cooling water inlet is connected with the unidirectional water inflow head.
In sum, the utility model advantage: cooling water flows between inner bag and outer roll body, and on inner bag, is provided with flight, and cooling water is extended at the heat exchanger time of cold water roller, has reduced the consumption of cooling water, makes simultaneously cooling effect more even.
The accompanying drawing explanation
Fig. 1 is the utility model Facad structure schematic diagram;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is the schematic diagram of inner bag.
Wherein, 1, outer roll body; 2, inner bag; 3, flight; 4, go out bucket; 5, flange; 6, bearing block; 7, fore side bearing block; 8, unidirectional water inflow head.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described in detail.
The utility model provides a kind of double-deck cold water roller, and as shown in Figure 1 to Figure 3, this chill roll comprises outer roll body 1 and inner bag 2, inner bag 2 is arranged on outer roll body 1 inside, and between outer roll body 1, space is arranged, make the cooling water can be from space, passing through, thereby externally roll body 1 carries out cooling.Inner bag 2 is connected by flange 5 with the end axle, and inner bag 2 is provided with flight 3, and flange 5 is provided with apopore; End axle inside is provided with runner; One end of runner is connected with inner bag 2 water inlets, and the other end is connected with cooling water inlet.Cooling water, from upstream end axle inside, cooling water inlet, enters two runners between flight 3 from the water inlet of inner bag 2.Flight 3 has increased the flow process of cooling water in inner bag 2 peripheries, and increased the contact time of its external roll body 1, has reduced the consumption of cooling water and electric energy, cost.
Further, apopore with go out bucket 4 and be connected.
Further, going out bucket 4 is fixed on bearing block 6.
Further, cooling water inlet is connected with unidirectional water inflow head 8, and unidirectional water inflow head 8 is fixed on fore side bearing block 7.
Although by reference to the accompanying drawings the specific embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
