Gate device

Abstract

The invention relates to a gate device ( 50 ) for use in conveying devices ( 10 ) for the automatic charging of small-sized solid fuels ( 3 ), especially wood pellets, characterized by a chamber ( 52 ) which is movable by means of a slide element ( 53 ), comprising a filling opening ( 51 ) and an outlet opening ( 56 ), with the slide element ( 53 ) releasing the filling opening ( 51 ) for filling the chamber ( 52 ) with solid fuel ( 3 ) in the filling position while the outlet opening ( 56 ) is closed, and the slide element ( 53 ) closing the filling opening ( 51 ) in a second position by moving the chamber ( 52 ) while simultaneously the chamber ( 52 ) can automatically be discharged via the outlet opening ( 56 ) which is released in the second position.

1 . A gate device ( 50 ) for use in conveying devices ( 10 ) for the automatic supply of small-sized solid fuels ( 3 ), especially wood pellets, characterized by a chamber ( 52 ) which is movable by means of a slide element ( 53 ) between a filling position and a discharging position, comprising a filling opening ( 51 ) and an outlet opening ( 56 ), with the slide element ( 53 ) releasing the filling opening ( 51 ) for filling the chamber ( 52 ) with solid fuel ( 3 ) in the filling position while the outlet opening ( 56 ) is closed, and the slide element ( 53 ) closing the filling opening ( 51 ) in the discharging position while simultaneously the chamber ( 52 ) can automatically be discharged via the outlet opening ( 56 ) which is released in the discharging position. 
   
   
       2 . A gate device ( 50 ) according to  claim 1 , characterized in that a fuel separator ( 40 ) is arranged on the filling opening ( 51 ) of the chamber ( 52 ), which separator conveys the solid fuel ( 3 ) into the chamber ( 52 ) of the gate device ( 50 ). 
   
   
       3 . A gate device ( 50 ) according to  claim 1 , characterized in that a fuel storage container ( 20 ) of a furnace ( 8 ) is arranged on the outlet opening ( 56 ) of the chamber ( 52 ). 
   
   
       4 . A gate device ( 50 ) according to  claim 3 , characterized in that the longitudinal axis (A) of the gate device ( 50 ) intersects the longitudinal axis (B) of the fuel storage container ( 20 ) under an angle (α) of 35 to 60°. 
   
   
       5 . A gate device ( 50 ) according to  claim 1 , characterized in that the movement of the slide element ( 53 ) occurs through a crank drive ( 60 ). 
   
   
       6 . A gate device ( 50 ) according to  claim 5 , characterized in that the slide element ( 53 ) is connected via a connecting rod ( 61 ) with the crank drive ( 60 ). 
   
   
       7 . A conveying device ( 10 ) for the automatic charging of small-sized solid fuels ( 3 ), especially wood pellets, comprising a gate device ( 50 ) according to  claim 1 , characterized in that the gate device ( 50 ) is arranged between a fuel separator ( 40 ) and a fuel storage container ( 20 ), with the charging of fuel to the chamber ( 52 ) of the gate device ( 50 ) occurring pneumatically. 
   
   
       8 . A conveying device ( 10 ) for the automatic charging of small-sized solid fuels ( 3 ), especially wood pellets, comprising a gate device ( 50 ) according to  claim 1 , characterized in that the gate device ( 50 ) is arranged between a fuel separator ( 40 ) and the combustion chamber of a furnace ( 8 ). 
   
   
       9 . A method for the automatic charging of small-sized solid fuels ( 3 ), especially wood pellets, characterized in that a slide element ( 53 ) of a gate device ( 50 ) according to  claim 1  releases in a first position a filling opening ( 51 ) arranged on a side of the chamber ( 52 ) facing the fuel separator ( 40 ), the solid fuel ( 3 ) is supplied via the fuel separator ( 40 ) to the chamber ( 52 ), thereafter the slide element ( 53 ) is moved to a second position, with the filling opening ( 51 ) being closed and an outlet opening ( 56 ) opposite of the filling opening ( 51 ) being released, so that a discharging of the chamber ( 52 ) of the gate device ( 50 ) occurs.
