Atomization device

Abstract

The atomization device comprises a motor ( 1 ) rotatably driving a spinning disc ( 2 ) by means of a rotating shaft ( 3 ), and cooling means for cooling said spinning disc ( 2 ), wherein said cooling means comprise a cooling circuit ( 4 ) extending around at least one portion of the rotating shaft ( 3 ) and below at least one portion of said spinning disc ( 2 ). The invention allows providing an atomization device in which the rotating shaft of the motor is perfectly aligned with the spinning disc, thereby avoiding the use of mechanical transmission elements.

1 . Atomization device comprising a motor rotatably driving a spinning disc by means of a rotating shaft, and cooling means for cooling said spinning disc, wherein said cooling means comprise a cooling circuit extending around at least one portion of the rotating shaft and below at least one portion of said spinning disc. 
     
     
         2 . Atomization device according to  claim 1 , wherein the cooling circuit comprises at least one inlet into the lower area of the spinning disc and at least one outlet for the liquid coolant. 
     
     
         3 . Atomization device according to  claim 2 , wherein the at least one inlet and the at least one outlet for the liquid coolant are located around and to the sides of the rotating shaft of the spinning disc. 
     
     
         4 . Atomization device according to  claim 1 , also comprising at least one sealing gasket arranged between a stationary base and the spinning disc. 
     
     
         5 . Atomization device according to  claim 4 , also comprising at least one sealing gasket arranged between the stationary base and the rotating shaft. 
     
     
         6 . Atomization device according to  claim 4 , wherein said at least one sealing gasket is made of graphite or another sliding seal material. 
     
     
         7 . Atomization device according to  claim 4 , wherein said at least one sealing gasket is arranged in a stationary manner. 
     
     
         8 . Atomization device according to  claim 1 , wherein said spinning disc and said rotating shaft consist of a single part or multiple parts. 
     
     
         9 . Atomization device according to  claim 1 , wherein the spinning disc is made of metal or ceramic. 
     
     
         10 . Atomization device according to  claim 1 , wherein the spinning disc comprises a refractory, anti-corrosive and/or anti-wear ceramic coating on its outer surface. 
     
     
         11 . Atomization device according to  claim 1 , wherein the spinning disc has a diameter comprised between 20 and 200 mm. 
     
     
         12 . Atomization device according to  claim 1 , wherein the spinning disc has a thickness comprised between 1 and 15 mm. 
     
     
         13 . Atomization device according to  claim 1 , comprising at least one bearing, or friction bearing, placed between the rotating shaft and the static base. 
     
     
         14 . Atomization device according to  claim 1 , wherein the cooling circuit is a closed circuit.
