  • Another object of the invention is to provide a drying tunnel for ceramic products whose ventilation structure is easily modifiable.
  • the subject of the invention is a drying tunnel module for ceramic products arranged on a means of transport traversing the tunnel from upstream to downstream, the module individually ensuring the distribution, the extraction and the temperature control, humidity and speed, air drying ceramic products, characterized in that it comprises an upstream end and a downstream end, an annular air distribution sheath in the vicinity of one of its ends, and a sheath annular extraction of air in the vicinity of the other of its ends.
  • the annular sheaths have orifices capable of ensuring the circulation of air in the module.
  • the orifices are distributed on the facing faces of the annular sheaths.
  • tubes are arranged between the annular sheaths to ensure the distribution or extraction of air in the module.
  • a tube has an open end, a closed end and a line of perforations extending from one end to the other.
  • a tube has its end open in an orifice of the distribution sheath, and its closed end in an orifice of the extraction sheath.
  • a tube has its open end in an orifice of the extraction sheath and its closed end in an orifice of the distribution sheath.
  • the module comprises a bottom and a top, articulated along a longitudinal line, the top pivoting on the line under the action of an actuator.
  • the annular sheaths consist of two parts, a part in the bottom of the module and another part in the top of the module.
  • the invention also relates to a drying tunnel for ceramic products arranged on a conveyance traveling through the tunnel from upstream to downstream, characterized in that it consists of modules of identical transverse dimensions.
  • the tunnel 1 for drying ceramic products consists of a series of modules 2 of identical transverse dimensions, juxtaposed and aligned.
  • the aligned modules 2 are all traversed by a transport means 3 which transports ceramic products 4 to be dried, from the upstream inlet to the downstream outlet of the tunnel 1.
  • the transport means 3 is designed to allow the drying air to pass through. through openings. It may consist of a perforated continuous band, a sheet of spaced belts parallel to the axis of the modules, a set of spaced crosspieces perpendicular to the axis of the modules, and connected by chains, a perforated belt or any other means. equivalent.
  • Each module 2 is equipped with individual means of ventilation and adjustment of temperature and humidity.
  • the drying of the ceramic products is ensured by exchange with an air controlled by the module, in temperature, humidity, and speed on the walls of the ceramic products.
  • All modules are of identical cross-sectional dimensions and individually configurable in terms of air quality (temperature and humidity) and ventilation speed. The modules can have different lengths.
  • Each module 2 consists of a bottom 5 and a top 6, articulated along a longitudinal line 7.
  • the module can be opened for the introduction of the transport means 3, the adaptation of the means of drying, and closed for carrying out tunnel drying.
  • the module 2 With respect to the direction of travel of the transport means 3, identified by the arrow 8, the module 2 has an upstream end 9 and a downstream end 10.
  • the module 2 comprises in the vicinity of its ends 9, 10, annular sheaths 11, 12, respectively, to ensure the flow of air in the module.
  • the annular sheath 11 which is upstream is a drying air extraction sheath.
  • Sheath annular 12 downstream is a drying air distribution duct.
  • the upstream annular sheath is a drying air distribution sheath
  • the downstream annular sheath is a drying air extraction sheath.
  • a ventilation device outside the central space of the module 2, a ventilation device, helical or centrifugal, makes it possible to create a pressure difference between the two sheaths 11 and 12, to ensure the circulation of air in the module.
  • a heating battery provides thermal energy to maintain the air temperature at the desired setpoint.
  • An outside air intake and an air extraction make it possible to renew the drying air.
  • annular sheaths 11, 12 On the annular sheaths 11, 12 are arranged orifices, respectively 13, 14, adapted to ensure the flow of air in the module.
  • the orifices 13, 14 are distributed on the facing faces of the annular sheaths 11, 12.
  • the orifices 14 distribute the drying air and the orifices 13 extract the air which circulates substantially from the downstream upstream in the module.
  • the distribution and extraction of the drying air are provided substantially perpendicularly to the transport means 3, via distribution tubes 15 and extraction tubes 16.
  • a distribution or extraction tube 16 has an open end 17, a closed end 18 and a line of perforations 19, extending from one end to the other.
  • the open end 17 is fixed in an orifice 14 of the distribution sheath 12
  • the closed end 18 is fixed in an orifice 13 of the extraction sheath 11
  • the line perforation 19 is oriented to ensure the drying of the ceramic products 4 disposed on the belt 3.
  • the open end 17 is fixed in an orifice 13 of the extraction sleeve 11
  • closed end 18 is fixed in an orifice 14 of the distribution sheath 12
  • the line of perforations 19 is oriented to ensure the suction of drying air Ceramic products 4.
  • the distribution and extraction tubes 16 are identical and interchangeable.
  • the arrangement of the air distribution and air extraction tubes is adaptable for optimum drying efficiency of the ceramic products.
  • the distribution tubes 15 are all disposed in the bottom 5 of the module and the extraction tubes 16 in the top 6 of the module.
  • the distribution tubes 15 are all arranged in the top 6 of the module and the extraction tubes 16 in the bottom 5 of the module.
  • the distribution tubes 15 are arranged on a lateral part of the module, and the extraction tubes 16 on the opposite lateral part ( figure 5 ).
  • the distribution tubes 15 and the extraction tubes 16 are arranged alternately on the entire annular distribution and extraction respectively sheath.
  • the perforations 19 of the distribution tubes 15 and the extraction tubes 16 are of dimensions and shapes adapted to the type of ventilation that it is desirable to produce in the module and on the ceramic products.
  • the orientation of the perforation lines 19 is adjusted relative to the ceramic products to obtain optimal drying.
  • the introduction of the distribution tubes 15 and the extraction tubes 16 and the orientation of the perforation lines 19 are easy because of the possible opening of the modules 2, the upper 6 pivoting on the hinge line 7 under the action of an actuator 20. Once the top 6 raised, access to the interior of the module 2 is ensured, regardless of the position of the module 2 in the tunnel 1 drying.
  • the annular sheaths 11, 12 are constituted in two parts, a part in the bottom 5 of the module and another part in the top 6 of the module 2.
  • each module is individually adjusted, and the number of modules is adapted to ensure optimal drying of ceramic products.
  • the drying tunnel consists of modules of identical transverse dimensions, individually ensuring the admission, extraction and temperature, humidity and speed control of the drying air of ceramic products.
  • An advantage of the drying tunnel described relates to the mixing of the drying air. Indeed, ventilation being provided within each module, it can be realized a change in the ventilation at each passage from one module to the next. This arrangement makes it possible to control the longitudinal transfers between the modules and generally between the entrance and exit of the tunnel.
  • Another advantage of the drying tunnel according to the invention is that its useful length is variable according to the needs, and adaptable by adding or removing one or more modules or simply by the commissioning or shutdown of modules.
  • Another advantage of the drying tunnel according to the invention is that it consists of modules whose transverse dimensions are identical but whose length may be different to ensure particular drying conditions, for example.
