Definitions
- the present invention relates to a device for cooling a long moving product.
- Devices of the type under consideration essentially comprise an elongated tube traversed by a cooling liquid (usually water) and through which also passes a product which takes a long time to cool.
- a cooling liquid usually water
- the tube is equipped, at one end, with a coolant supply head and at the other with a separator whose role is to dissociate, at the exit of the tube, the product in movement from its liquid envelope.
- the object of the present invention is precisely to provide a device, avoiding the drawbacks of known devices which can be used for high flow rates of cooling fluid.
- the subject of the invention is a device for cooling a long moving product comprising an elongated tube traversed by a cooling liquid and in which the product to be cooled also passes, fitted internally with means for centering the product constituted by tubular elements coaxial with the tube and having a central passage whose diameter is less than the internal diameter of the tube, said passage being preceded, in the direction of travel of the product, by an introduction cone, device characterized in that the means for centering have peripheral longitudinal channels, distributed around the central passage.
- the long product to cool, referenced 7, passes right through the device in a longitudinal direction.
- the length of the tube 1 has been deliberately reduced compared to its internal diameter.
- the cooling tubes of the type considered are several meters long, generally of the order of 4 to 6 meters, while their internal diameter, which of course depends on the range of formats of the products to be cooled, however exceeds rarely about 10 cm.
- the tube 1 is generally not made in one piece, but in several elementary sections 11, for example of about 2 meters in length each, connected one after the other. by screw crowns, referenced 12.
- the tube 1 has locally centering means 13.
- These centering means are constituted by a tubular element coaxial with the tube!, which can advantageously be interposed between two consecutive sections 11 and which defines a central passage 14 of diameter smaller than the inside diameter of the tube 1.
- the guide of the product in movement 7 through the centralizer 13 is ensured by an insertion cone 15 produced by appropriate machining of the internal profile of the centralizer.
- periphery channels risks 16 have been provided longitudinally in the thickness of the centering device 13.
- the invention thus succeeds in reconciling the two opposing imperatives that are, on the one hand the centering of the product in movement which ensures the homogeneity of its cooling and, on the other side, the passage of water whose more or less "easy” character conditions the efficiency of this cooling.
- the sum of the sections of the central passage 14 and the peripheral channels 16 is substantially equal to the interior section of the tube 1.
- 0 ⁇ t 63 mm
- 0 ⁇ c 45 mm
- the diameter of the peripheral channels 16, noted 0 ⁇ p is 14 mm.
- the aforementioned variant is produced using a centralizer 13, the peripheral channels 16 of which are, as shown in FIG. 3, ten in number.
- peripheral channels are not parallel to the axis 10 of the tube, but slightly inclined with a downward slope in the direction of circulation some water.
- the set of peripheral channels 16 thus gives the cooling water a circulation converging on the product, which makes it possible to reconstitute in good conditions downstream of the centralizer the liquid layer which envelops the product to be cooled.
- the channels 16 are produced so that their outlet ends 18 have an angular offset around the axis 10 relative to the corresponding inlet ends 19. It is understood that this embodiment gives circulation of water, at the outlet of the channels, an overall gyratory movement around the product to be cooled.
- the centralizer 13 fulfills an additional function.
- "deviator” which acts on the liquid envelope surrounding the product, by transforming the rectilinear circulation of this envelope, upstream of the centralizer, into a circulation of helical type, downstream of the centralizer.
- One advantage of this variant is to allow, while maintaining a given relative speed of water with respect to the product, to increase the residence time of the water in the tube, or, at a given residence time, to reduce the length of the tube.
- Another advantage lies in the fact that, by centrifugation effect, the separation of water and product at the outlet of the tube is appreciably facilitated.
- This variant embodiment also accommodates a radial offset from the outlet ends 18 towards the axis 10, which makes it possible, as previously, to cause the water to converge on the product at the outlet of the channels.
- the channels 16 can be rectilinear or, preferably, curved, which allows a greater angular offset of the outlet ends 18 without however causing sudden changes in the direction of water circulation.
- the variant illustrated in FIG. 2 is preferably suitable for water-product circulation in "co-current".
- FIG. 4 shows another embodiment which can be described as “universal” since it accommodates both a circulation of the "co-current” type and "counter-current” type.
- the central passage 14 of the centering device is extended on one side as on the other by an introduction cone 15 (respectively 15 ′) which guides the product, whatever the direction of movement of the latter.
- the peripheral channels 16 are shaped like an open V, which makes it possible to converge the cooling water on the product at the outlet of the centralizer, regardless of the direction of water circulation.
- the introduction cone 15, which precedes the central passage 14, is preferably dimensioned so that its large base has a diameter at least equal (advantageously greater) to the internal diameter 0t of the tube 1.
