Two-section type waste incinerator

A two-section type waste incinerator, comprising an incinerator body, a material pusher, a primary air chamber, a lateral girder, a fixed beam, a fixed grate-piece, a movable beam and a movable grate-piece, wherein a slag removing port (27a) is provided at a tail portion of the bottom end of the incinerator body (27), a material feeding bunker (27b) and a smoke outlet (27c) are provided at a front portion and a rear portion of the top end of the incinerator body (27) respectively, a material push platform (27d) is provided under the material feeding bunker (27b), the material pusher (28) is provided above the material push platform (27d), the fixed beam (2) which is mounted on the lateral girder (1) passes through grooves provided at tail portions of the fixed grate-pieces (3) positioned in the same row to form a fixed grate-plate, the movable beam (4) which is mounted on a lever passes through grooves provided at tail portions of the movable grate-pieces (5) positioned in the same row to form a movable grate-plate, the movable grate-plate and the fixed grate-plate are overlapped front and back and arranged with an interval to be assembled into a grate, heads of the grate-pieces are all provided with primary air holes, characterized in that:

• A. The grate is divided into two sections from a high point to a low point, i.e., an upper section and a lower section, the upper section is a pusher type section (6) and the lower section is a reverse pusher type section (7), all heads of the grate-pieces on the pusher type section (6) face toward a low point of the grate, and all heads of the grate-pieces on the reverse pusher type section (7) face toward a high point of the grate;
• B. Each movable beam (4) on the same section of the grate is equipped with left and right levers disposed side by side, the left and right levers are supported by a supporting roller device respectively and are connected to the movable beam (4) to form a lever frame, and an end of the lever frame is connected to a front swing arm driving mechanism or a lateral swing arm driving mechanism or a front straight driving mechanism.
