Definitions
- Heating rollers are used in a very large number of branches of industry whenever it is a question of bringing to a given temperature or drying a product in the form of a film, a sheet or a 'a plate. This is particularly the case in the leather, stationery, plastics, rubber, etc. industries.
- the simplest heating method consists, as shown in FIG. 1, of placing inside a cylinder (2) a certain number of electrical resistors (3) rotating with the cylinder and supplied by the rotor (4). .
- This type of cylinder has significant drawbacks, however, since the impossibility of performing a very fine distribution of the electrical resistances results in significant temperature differences along a generator and along a circumference.
- the fluids used are, depending on the applications and the temperature ranges, water, heat pipe oils, steam or specialized fluids.
- the calorie production system (5) is external to the consumer cylinder (6), whether it is a centralized system (for a cylinder bank) or an individual system for each cylinder. Calories are supplied by electrical resistors (7), oil, gas and coal burners - (steam) in the generator outside the cylinder. A temperature sensor (8) measures the temperature of the fluid and regulates it.
- the heat transfer fluid After the heat transfer fluid has been brought to the desired temperature of the receiver, either directly or indirectly by mixing, it is conveyed by a system of pumps (9) and is introduced into the cylinder by a rotary joint (10) ensuring the sealing.
- the fluid circulates either inside the cylinder (technique known as the hollow body), or in an annular space created at the periphery of the cylinder between the outer ferrule and a second inner ferrule, or in even more efficient systems inside spirals or rectilinear channels (12) judiciously distributed and crossed.
- the objective is to ensure a circulation at high speed of the heat transfer fluid, so that the calories consumed by the treated product are replaced as quickly as possible without preferential heating on one side or another.
- a fluid accelerator element In the case of fluids, the existence of a fluid accelerator element (pump) is essential. In the case of steam, the pressure difference is sufficient to ensure the circulation of the fluid at high speed, the supply of calories taking place by conduction and partially by condensation.
- the so-called rotating heat pipe technique in which, as shown in FIG. 3, the cylinder (13) comprises, in the immediate vicinity of the product to be treated, an annular space (14) placed under a high vacuum and partially filled with a heat transfer liquid (15) located, due to the high depression of the chamber (14) in which it remains, in a state of constant vaporization over the entire temperature range of use of the cylinder.
- this heat transfer fluid is to ensure, in the same way as the fluid in the cylinders described above, a circulation of steam at very high speed (immediate compensation for temperature differences) and supply of calories by condensation.
- the supply of calories is generally made from inside the cylinder by the heating mode of the "short-circuit transformer" (16) consisting of creating, from a fixed winding at the Inside the cylinder, a magnetic field which by short-circuit looping in the metallic mass of the cylinder (in rotation) releases by Joule effect the calories necessary for the system.
- This type of cylinder is extremely efficient on the. in terms of temperature regulation, thanks to the heat transfer fluid and in terms of calorie creation by transformer effect.
- it has the drawback of being relatively expensive in terms of implementation, due to the high cost of the electrical windings required, which generally limits its application to cylinders of very small dimensions.
- thermocouple This is an important difference compared to the previous type of cylinder where the fluid is warmed up outside the rotating cylinder, it is simple to measure the temperature of the fluid before it enters the system, the thermocouple then being static and the regulation system therefore having an acceptable cost.
- the present invention aims to remedy these drawbacks.
- the fixed body is regulated to a temperature close to the temperature of use of the cylinder by various devices, which can be either a circulation of hot fluid, or electrical resistances, or other means capable of bringing or removing from the body the calories necessary to allow it to reach the desired thermal balance.
- the supply of calories is done in an extremely simple way, since the hot body is fixed inside the cylinder, avoiding components, such as rotary joints for a fluid system, or rotary contacts for an electrical supply, which would be necessary if the body was mobile.
- the annular volume delimited between the two walls of the shell, is permanently depressed. and is partially filled with a fluid, which is, due to its thermodynamic characteristics and the degree of vacuum, in permanent equilibrium between a vapor phase and a liquid phase, over the entire range of temperatures of use of the cylinder .
- This highly efficient heat transfer system located in the rotating part of the cylinder ensures temperature balance over the entire surface of the cylinder due to the very high speed circulation of steam in the closed and vacuum enclosure. constituted by the annular volume delimited by the two walls of the shell.
- the fixed body has, in cross section, a shape of a circular sector, of axis corresponding to the axis of the cylinder, and of radius slightly less than the radius of the inner wall of the ferrule.
- the heat transmission system between the fixed body and the shell can be done by radiation or convection.
- the means for transmitting calories between the fixed body and the inner wall of the shell consist of a blade of liquid, chosen for its stability at the temperature of use.
- the rotary part of the cylinder constitutes a closed volume inside which the heating fixed body is located.
- the fixed body extends over a sector, for example a quarter of a circle situated below the axis of the cylinder, and the level of the contact liquid is also situated below the axis of the cylinder.
- the seal provided by the rotating part of the cylinder may be sketchy, since the level of liquid does not exceed the level of the axis. It is therefore a type of sealing that has no common measure with that required by rotary seals which are required to be absolutely sealed, even under relatively high operating pressures.
- the contact liquid having only a simple function of transmission of calories by thermal conductivity between the fixed body and the rotating shell, it is not necessary, contrary to the conditions required in conventional cylinders, ensure a speed of movement im carrying the liquid to carry out the transfer of calories, and simultaneously the balancing of the temperatures, this being ensured by the heat transfer fluid inside the shell.
- This cylinder is also equipped with a temperature regulation device comprising a measurement probe, located in the fixed body near the connection liquid between the fixed heating body and the inner wall of the shell.
- FIG. 4 represents a perspective view of this heating cylinder, one end of which is partially cut away.
- This cylinder comprises a cylindrical shell comprising two concentric walls, respectively, exterior (20) and interior (22), delimiting an annular volume (23), this shell being integral in rotation with the shaft (24) of the cylinder.
- the annular volume (23) is permanently depressed, and is partially filled with a fluid (25) which, due to its thermodynamic characteristics and the degree of vacuum, is in permanent equilibrium between a vapor phase and a liquid phase, over the entire operating temperature range of the cylinder.
- a fixed body Inside the ferrule, is disposed a fixed body (26) having, in cross section, a shape of a circular sector, corresponding to a quarter of a circle, of axis corresponding to the axis of the cylinder and of slightly smaller radius. to the radius of the inner wall of the ferrule.
- This fixed body (26) is equipped with heating means constituted by resistors (27) in the embodiment shown in the drawing. Between the fixed body (26) and the rotating part, and more precisely the inner wall (22) thereof, the heat transfer is ensured by a blade of a liquid (28) the level of which is located below the axis of the cylinder, and which is chosen to have good stability at the operating temperature of the cylinder.
- This cylinder finally has a temperature regulation device, the probe (29) of which is disposed in the fixed body (26) near the liquid ensuring thermal contact between the fixed body (26) and the inner wall (22) of the shell. .
- the invention brings a great improvement to the existing technique by providing a heating cylinder of simple design, because the hot body is fixed and requires only simple means of implementation both on the plan of the creation of the calories that of the regulation of the temperature, that the heat transfer fluid, located in the rotating part of the cylinder, ensures an excellent temperature balance on all the surface of the cylinder, and finally that the transfer of calories between the body fixed and the rotating part, is obtained by a liquid which does not require strict sealing conditions.
