Definitions
- the present invention relates to improvements in rolls for paper making machines and the like, and more particularly to an improved arrangement for maintaining the temperature of a roll within a permissible limit.
- a roll is one covered with a composition material wherein the composition becomes hot with use, and unless cooled, will deteriorate or become too soft for continued use.
- one of the rolls in a roll couple is frequently covered with a composition material such as material known to the trade as Beltex.
- the opposing roll will be a polished metal roll which will be heated to a maximum temperature of 250F.
- Relatively high nip pressures are employed in these arrangements on the order of a maximum of I700 pli, and it is essential that the composition cover of the one roll not be permitted to reach 250, or it will soften and deteriorate.
- a further object of the invention is to provide an improved roll structure which is cooled by a circulating coolant wherein the quantity of coolant circulated is substantially reduced while still obtaining effective cooling.
- a further object of the invention is to provide an improved cooled roll structure utilizing a liquid coolant which does not drain to become overheated when it is stopped and wherein the coolant circulating construction is improvedover structures heretofore available.
- FIG. I is a somewhat schematic vertical sectional view taken through a roll assembly constructed in accordance with the principles of the present invention.
- FIG. 2 is a fragmentary enlarged view showing details of the roll construction.
- FIG. 3 is a sectional view taken substantially along line IIIIII of FIG. 1.
- a roll mechanism including a first roll 10, forming a pressure nip with a second roll 11.
- the construction provides a super-calender wherein a paper web is passed through the nip to be calendered. While advantages are obtained in this particular environment of the invention, it will be understood that certain features of the invention may be utilized in other arrangements, but for this description, the structure will be described as used in a paper machine.
- the roll 1 l is heated to a temperature of on the order of 250F. This temperature is too hot for the resilient composition covering 13 of the roll 10.
- the roll 10 has a roll shell 12 of metal which provides a rigid base on which the covering material 13 is supported. For cooling the covering material 13, heat is transmitted through the metal base 12 to be removed by a coolant in a manner which will be described.
- disks l4 and 15 are pressed into the ends of the roll shell, and these disks carry journals l6 and 17 to be supported in bearings for rotatably carrying the roll 10.
- an inner shell 18 Coaxially mounted within the outer shell 12 is an inner shell 18.
- This inner shell defines a thin annular chamber 20 between its outer surface and the inner surface of the outer shell 12. Coolant is delivered and maintained in an axial flow through the thin annular chamber 20 by being admitted through a pluralityof openings 19 through the inner shell. These openings 19 are constructed so that a greater flow is received into the end 200 of the annular chamber than the end 20b.
- the end 20b is adjacent coolant exhaust passages 23 through which the coolant is removed from the chamber 20. In other words, a greater amount of coolant is admitted to the annular chamber 20 at the end 20a which is remote from the coolant exhaust passages 23 than in the end 20b which is adjacent the coolant ex haust passages 23.
- the openings are arranged uniformly annularly around the inner shell and uniformly spaced in an axial direction.
- the diameter or size of the. openings becomes progressively larger at a greater distance from the exhaust passages 23.
- the diameter of the openings D is greater than the diameter of the openings D.
- the exhaust passages 23 are conveniently drilled to extend radially inwardly from the annular chamber 20 and communicate with an annular passage 24 leading out through the journal 16.
- a line 24a is connected to the annular passage and contains a pressure control valve 25. This is set at a low pressure sufficient only to prevent the drainage of coolant liquid from the annular chamber 20 when the roll stops. In other words, the valve 25 prevents drainage due to gravity.
- Coolant is delivered to the inner chamber 21 within the inner shell through a line 26 connecting to a hollow coaxial passage 22 through the journal 16. Coolant is delivered through the line 26 by pump 27.
- pump 27 the flow of coolant into and out of the roll is conveniently arranged through coaxially located passages.
- the temperature of the coolant may be measured such as by a device located at 28 in the line 24a.
- This coolant detection device may be connected to control the operation of the pump 27 so that coolant is delivered at a rate to maintain a uniform predetermined temperature for the roll cover 13.
- FIG. 2 shows in somewhat greater detail the relative location of certain of the elements.
- the disk 14 is formed with a bevelled face 14a on its inner edge so that it coaxially seats the inner shell 18.
- the end of the inner shell 18a seats so as to prevent leakage of coolant.
- the disk head 14 has an annular surface 14b to provide a flow space for coolant flowing through the exhaust passage 23.
- the holes 19 in the inner shell are countersunk, as in 19a, from their outer surface to prevent clogging of the openings.
- the openings are so arranged, as above stated, by size so that a greater amount of fluid is passed across the inner surface of the outer shell for the longest distance between the large openings and the exhaust port, while a lesser amount flows from the inner chamber through smaller holes nearer to the exhaust port. This lesser amount of fluid remains in the heat transfer chamber for a shorter period of time. This results in a relatively even temperature level in the fluid across the entire roll face.
- the annular coolant chamber must be maintained relatively thin and preferably on the order between one-eighth to. one-fourth inch thick. As an example of a size relationship which is well suited, is a chamber which is three-sixteenth inch radial dimension.
- the holes leading into the space are arranged sequentially larger away from the exhaust opening 23. For example, if five holes are used along the length of the roll shell, the holes may be on the order of 3/32, Vs, /32, 3/16 and 541 inch in diameter.
- the size of the inlet and exhaust passages are not critical, except they must be sufficiently large to carry maximum coolant flow, and an inlet pipe on the order of 1 inch is well suited for the above dimensioned openings.
- the exhaust ports may be on the order of inch diameter with a plurality of ports provided uniformly circumferentially spaced with 8 exhaust ports being used.
- a temperature controlled roll mechanism for a paper machine or the like comprising in combination:
- a first roll having a roll shell with an inner rigid metal annular base and a covering of a composition having an upper temperature limit;
- a second opposing heated roll forming a roll couple with the first roll and being heated to heat the outer layer of said first roll;
- an inner shell positioned coaxially within the outer shell and defining a thin annular chamber therebetween and forming a hollow fluid receiving inner chamber within the inner shell;
- a temperature controlled roll mechanism for a paper machine or the like constructed in accordance with claim 1:
- openings are constructed so that a greater volume of flow passes from the inner chamber to the annular chamber at the end remote from said exhaust passage than at the end adjacent said exhaust passage.
- a temperature controlled roll mechanism for a paper machine or the like constructed in accordance with claim 1:
- openings are larger at the end of said inner shell remote from the exhaust passage than at the end adjacent said exhaust passage.
- a temperature controlled roll mechanism for a paper machine or the like constructed in accordance I with claim 1:
