PL127199U1 - Mechanical stoker for combustion of solid fuel - Google Patents

Abstract

The subject of the utility model is a mechanical grate for burning solid fuel, especially peas and fine coal. The mechanical grate for solid fuel combustion includes a furnace plate (1), a rotating ring (2), an elbow (3) in which a screw (4) and a driver (5) are placed. The outer surface of the furnace plate (1) has the shape of a cylinder (6), and the inner surface has the shape of a truncated cone (7), and the upper surface (8) ends with an outwardly turned flange (9). The upper surface (8) of the furnace plate together with the flange (9) is inclined outward with respect to the plane of the upper opening (10) of the furnace by an angle ()) in the range of 0.5 ° to 30 °. The furnace plate (1) with a collar (9) is seated on the upper edge of the air chamber (11). A rotating ring (2) is placed inside the firebox (1). In its lower part, the rotating ring (2) has a ring of catch elements (12). Ring of catch elements (12) cooperates with driver (5). The rotating ring (2) is mounted on the upper part of the elbow (3). A worm (4) with an extended shaft (13) is placed in the elbow (3). The bend (3) has an overhang (14) in the place of the bend on its outer surface, creating a flat plane. The riser (14) has an opening through which the extended shaft (13) of the worm (4) passes, at the end of which the driver (5) is mounted.
