The present invention relates to a drive device and auxiliary equipment in a stocker type incinerator for incineration of waste.

The stocker type incinerator is basically composed of 3-4 grates (dry stage, combustion stage and afterburner stage).

Each grate consists of a fixed end, drive end, shaft, drive arm, lever, fixed bar, drive bar, roller, grate and hydraulic cylinder, and the unique operation of each component effectively removes the waste incinerated in the incinerator. And burns and moves.

The most commonly used technology in Korea by incineration of waste is the use of stocker type incinerators. The grate composition and driving principle are that the grate is arranged in a stepped manner. Stokers that are transported little by little along the stairs are widely used.

However, in the case of a grate constructed in a stepped manner and driven by the forward and backward movement of the drive grate, a gap may occur between the drive grate and the fixed grate, and this gap may cause iron drift and metal to be caught, in which case the grate frame and the support are damaged. Foreign matter discharged into the gaps can cause fires and cause great dropouts.

In addition, in the case of a stalker type incinerator composed of stepped grate, the fixed grate of the drive grate is installed alternately in a row, and the drive grate increases the great wear of each grate by moving forward and backward between two fixed grate. And the grate of the fixed grate is a structure that is hung on each support bar, the frame and steel frame may be damaged by receiving a lot of load when the waste is accumulated by the crank on each grate.

In the case of a grate composed of one frame and one drive stage and a fixed stage separately from the cascade grate, the drive grate and the fixed grate are precisely divided so that only the respective roles are performed. It is much shorter, and if waste is not caught between the actuating grate and the stationary grate, it must be removed by human force with the incinerator stopped.

The present invention is to solve the problems caused by the forward and backward movement of the drive device in the conventional stepped stocker incineration device as described above and the problem of the drive device that is composed of a fixed grate frame and a drive grate frame to move forward, backward The grate drive system was configured as below to improve the operation and maintenance of the incinerator.

First, in constructing a stocker incinerator, the grate is installed as a driving grate and an auxiliary drive grate to drive the whole grate, and half of all grates operate as fixed grate and driving grate for a certain period of time. Improve operation of incinerator continuous operation by replacing and operating.

Second, it is possible to prevent the element of the incineration during operation of the incineration plant, by the movement of the drive grate, to prevent the element of the incineration of iron or metal which is caught in the gap of the grate frame when driving the drive device. Simultaneous operation of the auxiliary drive grate allows for effective removal of debris.

Stoker type incinerator drive device according to the present invention is composed of a drive grating and an auxiliary drive grating, the drive grating is a drive cylinder (1) for providing a linear driving force, one end is connected to the drive cylinder (1) and the other end is the main shaft A driving arm 15 connected to the driving shaft 15 to transmit the linear driving force of the driving cylinder 1 to the main shaft 3 as a rotational force, and one end to the main shaft 3 and the other end of the driving grating frame ( 7) a linear reciprocating guide while supporting the rail (10), a rail (10) fixed to a predetermined portion of the drive grate frame (7) forward, and the rail (10) rotatably connected to the lever (13). It consists of a roller 12 installed so that the auxiliary drive grating is a driving cylinder (2) for providing a linear driving force, one end is connected to the drive cylinder (2) and the other end is connected to the main shaft (5) drive cylinder (2) the linear drive force to the rotational force A driving arm 16 which is transmitted to the main shaft 5, a primary lever 14 fixed to the main shaft 5 and the other end rotatably connected to the driving grate frame 8, and 1 The lower lever is rotatably fixed to a predetermined portion of the drive grate frame 8 in front of the vehicle lever 14 and the upper end is composed of a secondary lever 17 rotatably fixed to the frame 8.

Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

Side view of a separate drive grate of the stocker type incinerator drive device according to the present invention, Figure 4 is a side view of the auxiliary drive grate separate from the stocker type incinerator drive device according to the present invention, Figure 5 is a front view of the stocker type incinerator drive device according to the present invention to be.

Referring to the drawings in the scoker type incinerator according to the present invention, the configuration of the driving grating is a drive connected to the driving grating main shaft 3 during the linear movement of the driving grating drive cylinder 1 based on the main shaft 3 of the driving grating. The main shaft 3 is rotated by the arc motion of the arm 15, and the drive grate frame 7 is arced by connecting the main shaft 3 and the drive grate frame 7 with the lever 13. The roller 12 is installed on the drive grate auxiliary shaft 3 which is not connected to the drive cylinder 1, and the drive grate frame 7 is connected to the rail 10, so that the drive grate main shaft 3 The rail 10 connected to the drive grate auxiliary shaft 5 during the arc motion is configured to perform a linear motion on the upper roller 12.

* The configuration of the auxiliary drive grate is assisted by the arc motion of the drive arm 16 connected with the auxiliary drive grate main shaft 4 during the linear movement of the auxiliary drive grate drive cylinder 2 with respect to the auxiliary drive grate main shaft 4. The main shaft 4 of the drive grate rotates, and the auxiliary drive grate frame 8 is arced by connecting the main shaft 4 and the auxiliary drive grate frame 8 with the auxiliary drive grate primary lever 14. Secondary lever grating is connected to the secondary drive grate frame in front of the secondary drive grate frame, and the secondary lever is installed on the upper side of the auxiliary drive grate support beam (6) to move the arc of the auxiliary drive grate main shaft (4). At the same time, configure so that you can do arc movements.

In the incinerator apparatus according to the present invention configured as described above, as the driving cylinders 1 and 2 are driven, the driving grate frame 7 and the auxiliary driving grate frame 8 perform arc motions of different trajectories. In particular, since the driving grate frame 7 is linearly driven along the roller 12 on one side and the other side of the supporting grate frame 7 is different from the auxiliary drive grating frame 8 composed of the arc motion. The waste transport is made.

Of course, only one side of the driving grate frames 7 and 8 may be driven while the other is fixed, and vice versa.
