An electrode sheet drying apparatus includes a plurality of hot air blowers each having a nozzle. The nozzle has a first hot air guide having a first guide surface, a second hot air guide having a second guide surface. The nozzle is configured to blow band hot air toward an obliquely upstream side. An angle formed between the first guide surface and an undried active material layer is set to an angle at which the band hot air travels toward an upstream side along the undried active material layer over a distance longer than or equal to 15 times as large as a gap from a first upstream-side edge to the undried active material layer even without a spread prevention part.

The present invention provides a conveyor belt tracking system for a dryer having a web of a mesh material having a protrusion extending along the length proximal one lateral edge and above a flat surface and a first generally cylindrical roller having a three-tiered slot for receiving the protrusion and two flanking shallow tracks for receiving base flanges.

An electrode sheet drying equipment, an electrode sheet manufacturing system including the same, and an electrode sheet drying method including an air-floating roller disposed downstream of a drying oven, and the air-floating roller is configured to spray hot air through multiple air spraying holes formed on the outer circumferential surface. Accordingly, the electrode sheet discharged from the drying oven in a partially undried state can be additionally dried, thereby preventing contamination of a transfer roller and/or equipment of the subsequent process.

An apparatus for drying an electrode plate includes a drying furnace configure to dry an electrode plate having a slurry coated thereon, an over-heated steam supplier configured to supply the drying furnace with over-heated steam as a drying heat source, a circulation fan configured to inhale at least some of the over-heated steam discharged from the drying furnace and to introduce the inhaled over-heated steam back into the drying furnace, an exhaust fan configured to inhale at least some of the gas exhausted from the drying furnace, and a heat exchanger configured to exchange heat of the exhaust gas supplied from the exhaust fan.

A machine for treating a fabric (T) with air, comprises a tunnel (10) for pneumatically transporting the fabric and means for injecting the air into the tunnel above and/or below the fabric and comprising at least one diverting valve (16;18) located substantially half way along the tunnel and having two channels (16a,16b;18a,18b) which are oriented to direct the air flow entering the tunnel in one direction or the other. The valve comprises an adjustable baffle (17;19) adapted to shut off access to the channels (16a,16b;18a,18b) either wholly or partly. In the treatment method of the invention, the air flow (F;F) entering the tunnel is divided into two unequal components (F.sub.1, F.sub.2; F.sub.1, F.sub.2) directed towards opposite ends of the tunnel.

The present invention provides a conveyor belt tracking system for a dryer having a web of a mesh material having a protrusion extending along the length proximal one lateral edge and above a flat surface and a first generally cylindrical roller having a three-tiered slot for receiving the protrusion and two flanking shallow tracks for receiving base flanges.

A drying oven for crosslinking a continuous mat of mineral or plant fibers includes a plurality of heating boxes through which the mat of fibers successively passes. At least one of the boxes includes, between an external insulating jacket of the drying oven and a central compartment of the box, an in-built hot-gas heating and recirculation device that includes at least one radial turbine mounted horizontally, the axis of rotation of which is arranged vertically, the turbine drawing hot gas along the axis through a gas outlet orifice of the central compartment after it has passed through the mat, and discharging it radially toward a recirculation device that recirculates the hot gas leaving the radial turbine to a gas inlet orifice of the compartment, and at least one heating device for heating the gas circulating in the box.

The present invention relates to an electrode sheet drying apparatus capable of preventing thermal wrinkles in a non-coated portion, and more particularly to an electrode sheet drying apparatus for drying an electrode sheet including a pair of coated portions each having an electrode active material applied to one surface of metal foil and a non-coated portion located between the pair of coated portions, the apparatus including a chamber configured to dry the electrode sheet therein, a heater provided at an upper part of the chamber, the heater being configured to adjust the temperature in the chamber to a temperature necessary to dry the electrode sheet, and at least one guide roll configured to guide movement of the electrode sheet in the chamber and to maintain tension of the electrode sheet, wherein a part of the electrode sheet is moved in a state of being spaced apart from the guide roll.

The present invention provides a textile dryer having a housing defining a chamber having an infeed and an outfeed. A separation wall extends through the chamber to create a first zone having a first ambient condition and a second zone having a second ambient condition. A first conveyor extends through the first zone and a second conveyor extends through the second zone. A controller is provided to allow an operator to independently select the speed and direction of the first conveyor and the second conveyor, and to independently select the physical conditions of the first ambient condition and the second ambient condition, and to maintain these settings during the operation of the dryer.

The present invention provides a conveyor belt tracking system for a dryer having a web of a mesh material having a protrusion extending along the length proximal one lateral edge and above a flat surface and a first generally cylindrical roller having a three-tiered slot for receiving the protrusion and two flanking shallow tracks for receiving base flanges.
