Description

[Detailed Description of the Invention] The present invention relates to a device for discharging ash that enters the pipe from the vertical pipe ventilation hole of the incinerator stirring section to the outside of the pipe.

While the incinerator is in operation, air is blown out of the pipes from the vent holes in the vertical pipes installed in the stirring section, so a small amount of ash gets into the pipes, but if there is no escape route, it will gradually accumulate. loading, especially at the start of operation,
If the air jet is not opened or stopped, such as when the engine is stopped, the air vents become clogged and the flow of air is obstructed, resulting in increased heat loss.

This idea was devised for the purpose of quickly discharging the ash that has entered the pipes to the outside without trapping them inside the pipes by providing a slit-shaped ash outlet at the bottom of each vertical pipe on the opposite side in the direction of travel.

To explain the configuration of the present invention with reference to the drawings, Fig. 1 is a front schematic diagram of an incinerator to which the proposed device is applied, and Fig. 2
The figures are a sectional view taken along the line A-A in Fig. 1, Fig. 3 is a front view in the direction of movement of the vertical pipe equipped with the proposed ash removal device, Fig. 4 is a sectional view taken along the line B-B in Fig. 3, and Fig. 5. FIG. 2 is a diagram showing the state of the vertical pipe and its surrounding area during operation in the furnace.

In the drawing, reference numeral 1 denotes an upright cylindrical furnace body, in which an upright rotating tube 2 is arranged at the center, several branch tubes 3 are connected radially to the top of the tube, and a rotary tube 3 is connected to the bottom of each branch tube. Furthermore, several vertical pipes 4 are connected, a series of ventilation holes 5 are made on the pipe side of each vertical pipe 4, and the bottom part 6 is closed, and a side surface (rear side) on the opposite side in the direction of movement of the vertical pipes is formed just above the lower end of the pipe. A slit-shaped ash outlet 7 is provided in the ash outlet.

Although the tube bottom 6 may be flat, it is particularly advantageous to form a downward slope 8 toward the ash outlet 7 in the direction of travel of the tube, as shown in the figure, for better ash discharge.

In the figure, 11 indicates a hearth, and 12 indicates a partially incinerated material to be treated.

Next, I will explain the action and effects.

When the material to be treated is fed into the furnace and ignited, the rotary tube 2 is rotated and air is blown into the tube, each vertical tube 4 advances in a circular orbit above the hearth and moves forward while stirring the material to be treated. At the same time, combustion air is ejected from each vent hole 5 onto the hearth.

As the combustion progresses in the furnace and the material to be treated turns into ashes, some of the ash rises into the furnace and enters the tubes 4 through the ventilation holes 5. Since the air is discharged into the air, there is no possibility that the air hole 5 will be clogged or that air will be deposited inside the pipe and obstruct air circulation.
