The present invention relates to a grate frame structure of the incineration apparatus, and more particularly, a grate frame installed inside the drying chamber in order to sufficiently dry the waste containing a lot of water and to put it into the combustion chamber so that combustion can be smoothly performed. It's about structure.

In general, a pyrolysis incinerator is an apparatus configured to be used for industrial or household use by incineration of waste to obtain thermal energy and operating a boiler using the heat as illustrated in FIG. A drying chamber (100) for drying (T) is formed, and a combustion chamber (300) in which waste (T) is incinerated is provided at the lower portion of the drying chamber (100), and a melting furnace (400) causing sparks in the combustion chamber (300). Is formed, the combustion chamber 300 is a secondary combustion chamber 500 is formed by the combustion of the gas is moved to the second side is moved to the boiler 600, such as to heat the water using the burned heat as described above. Consists of.

As a representative example of such an incinerator, Patent Registration No. 303882 "Combination combustion cocurrent pyrolysis incinerator" has been proposed.

On the other hand, such an incinerator is obtained by burning the waste to obtain energy, since the waste usually contains a large amount of water, it was an essential process to dry the waste so that the incineration can be performed smoothly.

To this end, it is equipped with a drying chamber in which waste is inputted and dried, and the waste is sufficiently dried in the drying chamber and then configured to be combusted by being introduced into the combustion chamber.

The drying chamber is generally composed of a grate frame formed by inclined pipes arranged at a predetermined interval at a predetermined interval so that the wastes are placed and dried by hot air. It is configured to dry the waste while passing through, and to dry the waste sufficiently while the hot air flows in and moves along the pipe forming the grate frame.

As such, the waste dried on the grate frame is naturally rolled into the combustion chamber side as the grate frame is inclined toward the combustion chamber, and combustion is performed.

Therefore, in order to burn smoothly, it is necessary that the waste is properly dried on the grate frame, but the conventional grate frame structure as described above simply forms a plane with a predetermined interval so that the waste can be settled. If only the waste is settled in the grate frame, there is a problem that the efficiency of drying is reduced because hot air is not easily introduced into the waste gap.

This causes a problem that the operation rate of the entire incinerator is also lowered, the necessity of a grate frame has emerged to dry the waste more smoothly.

The present invention has been made to solve the above problems, more specifically, having a grate frame composed of two stages so that the waste is placed at a predetermined interval on the grate frame of the top and bottom to be smoothly dried. The purpose is to obtain the grate frame structure of the incinerator.

In order to achieve the above object in the present invention, in the present invention, a plurality of pipes 240 are arranged at regular intervals to constitute a grate frame 200 installed in the drying chamber 100 of the incineration apparatus.

A pair of lower headers 220a and 220b and a pair of upper headers 250a and 250b are provided with a height difference, but the lower header 220b and the upper header 250b included in the drying chamber 200 are connected to a connection pipe ( 230 is connected between the lower headers 220a and 220b, and a plurality of lower pipes 240b are disposed while maintaining a predetermined interval to form a lower frame, while the pair of upper headers 250a are formed. A plurality of upper pipes (240a) between the (250b) formed by a number of groups arranged by a predetermined number to form a plurality of upper frame, each of the upper frame between the grate frame of the incinerator characterized in that it is configured to be spaced at a predetermined interval Suggest a structure.

In addition to the above-described basic configuration, each of the upper frame is characterized in that the two to six upper pipes 240a are arranged in a group.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

1 is a perspective view of a grate frame according to the present invention, FIG. 2 is a schematic cross-sectional view of an incineration apparatus to which the grate frame according to the present invention is applied, FIG. 3 is a partially enlarged cross-sectional view showing a part of the drying chamber in FIG. 4 is a longitudinal cross-sectional view of the grate frame according to the present invention installed in the drying chamber.

As shown, the grate frame 200 according to the present invention is composed of two stages spaced apart at a predetermined interval from the lower frame located on the bottom and the upper frame located on the lower frame.

The lower frame is arranged with a plurality of lower pipes 240a between the pair of lower headers 220a and 220b at regular intervals. If the space between the lower pipes 240b is too wide, waste T is not seated. If it is too narrow and is too narrow, hot air does not pass well, so adjust according to the size of waste (T). The lower pipe 240b has one end connected to the fixed pipe 260 extending from the lower header 220b received inside the drying chamber 100 without any fixing means and the other end is connected to the outside of the drying chamber 100. It is bolted and fixed to the fixed pipe 260 extending from the lower header 220a is located.

As described above, the one end of the pipe 240 is configured to simply fit into the fixed pipe 260 extending from the lower header 220b and the upper header 250b disposed inside the drying chamber 100. The expansion is to increase the length to absorb it to prevent distortion and to facilitate the coupling and separation.

According to the above, the lower frame is formed in a plate-like shape by a plurality of lower pipes 240b, and is configured to be seated on the lower frame when the waste T is introduced into the drying chamber 100.

On the other hand, the upper frame positioned on the lower frame is composed of a plurality of upper pipes (240a) is disposed between the pair of upper headers (250a, 250b) are coupled and fixed, the coupling method is the structure and same. However, the upper frame is composed of two to six upper pipes 240a in a group consisting of a plurality of arranged on the top of the lower frame, each of the upper pipes 240a consisting of 2 to 6 in a group The upper frame and the upper frame is formed to be spaced apart at regular intervals. That is, when viewed in a plane is a certain space is formed between the upper frame and the upper frame.

Here, the space between each upper frame is preferably configured to be spaced apart by the width of one upper frame, which can be variously adjusted in consideration of the size of the waste, and flows into the drying chamber 100 through this space. Waste (T) will be able to fall into the lower frame.

In addition, both ends of the lower header 220b and the upper header 250b positioned inside the drying chamber 100 are connected through a connecting pipe 230, and through the connecting pipe 230 to the outside of the upper frame. From the inlet 270 to be forced through the air flow from the upper frame to the lower frame is configured to be discharged through the outlet 280 formed in the lower frame to prevent the grate frame is overheated.

When explaining the operation of the grate frame according to the present invention configured as described above with reference to FIG.

As shown, the upper frame and the lower frame is spaced at regular intervals, and in particular, the upper frame is spaced at an appropriate interval for each upper frame. When the waste T is introduced into the drying chamber 100, some waste T is The upper frame is caught and some waste (T) is accumulated in the lower frame through the space between the upper frame and the upper frame.

When wastes (T) are accumulated in the upper frame and the lower frame as described above, a square (死角) is formed in the lower frame which is blocked by the upper frame so that the waste T does not accumulate. The waste (T) is dried while moving freely. This widens the area where hot air comes into contact with the waste (T), thereby improving the drying efficiency.

The waste (T) dried in such a grate frame is introduced into the combustion chamber 300 and ignited, and then burned and decomposed at high temperatures, and the ashes are hot-melted by a flame generated from the melting furnace while the ash is loaded in the melting furnace 400. After combustion, the generated gas is moved to the secondary combustion chamber 500 along the connection pipe 310 to be secondarily burned, and then, a part of the gas is covered by the boiler 600, and a part of the gas passes through the air preheating chamber 700 again. 100) and the waste (T) is dried to continuously dry the waste (T), to burn the dried waste (T), it is possible to repeat the operation to dry the waste (T) again using the combustion gas. To lose.

As the grate frame is composed of two stages as described above, the area where the hot air touches the waste becomes wider, so that the drying of the waste is much more efficient. Accordingly, the efficiency of the incineration apparatus may also be increased.
