A fixed plate vertical to the axis of the furnace body is fixedly arranged in the furnace chamber, the fixed grate is fixed between the fixed plate and the furnace body, a rotating shaft which is parallel to the fixed plate and has the same height with the bottom surface of the furnace body is further sleeved on the furnace body, one side of the rotary grate is fixedly connected to the rotating shaft, and a supporting plate for supporting the rotary grate is further arranged on the furnace body corresponding to one side of the rotary grate opposite to the side;
The fixed plate is adjacent to the rotating shaft and is positioned in the middle of the lower part of the hearth.
Furthermore, the height between the supporting plate and the bottom surface of the furnace body is not more than the height between the rotating shaft and the bottom surface of the furnace body.
Furthermore, the fixed grate is obliquely arranged.
Furthermore, a coal inlet is arranged on the furnace body corresponding to the rotary fire grate, and a charcoal inlet is arranged on the furnace body corresponding to the fixed fire grate.
Furthermore, the chimney is positioned at the top of the furnace body right above the fixed grate.
Furthermore, one end of the rotating shaft extends out of the furnace body, and the end part is connected with a driving unit for driving the rotating shaft to rotate.
When the high-efficiency coal-fired furnace provided by the invention is used, as the coke has good combustion performance and can be fully combusted in a short time, the coke is added on the fixed grate firstly, and after the coke is fully combusted, the fire coal is added on the rotary grate, and in the combustion process of the fire coal, part of the fire coal on the rotary grate can be poured on the fully combusted coke by rotating the rotary grate, so that the combustion of the fire coal is accelerated, and through the action, the gap between the fire coals can be increased, and the purposes of improving the full combustion rate of the fire coal and reducing the emission of black smoke and polluting the environment are achieved integrally.

FIG. 1 is a perspective view of a high efficiency coal fired furnace with a rotary grate in a non-rotated state;
FIG. 2 is a perspective view of the rotary grate of the high efficiency coal-fired furnace of the present invention from a side view;
Fig. 3 is a schematic view of a grate structure.
Description of reference numerals:
In the figure: 1. the furnace comprises a furnace body, a combustion chamber 2, a furnace ash chamber 3, a fixed grate 4, a rotary grate 5, a coal inlet 6, a charcoal inlet 7, a fixed plate 8, a rotating shaft 9, a support plate 10 and a chimney 11.
Detailed Description
It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.
The present invention will be described in detail below with reference to the embodiments with reference to the attached drawings.
the high-efficiency coal-fired furnace provided by the invention, as shown in figures 1 and 3, comprises a furnace body 1, wherein a fire grate is arranged in the furnace body 1, the fire grate divides a hearth into a combustion chamber 2 and a furnace ash chamber 3, the combustion chamber 2 is positioned above the fire grate, the furnace ash chamber 3 is positioned below the fire grate, and the fire grate comprises a fixed fire grate 4 and a rotary fire grate 5;
A fixed plate 8 vertical to the axis of the furnace body 1 is fixedly arranged in the hearth, the fixed grate 4 is fixed between the fixed plate 8 and the furnace body 1, a rotating shaft 9 which is parallel to the fixed plate 8 and has the same height with the bottom surface of the furnace body 1 is further sleeved on the furnace body 1, one side of the rotating grate 5 is fixedly connected to the rotating shaft 9, and a supporting plate 10 for supporting the rotating grate 5 is further arranged on the furnace body 1 corresponding to one side of the rotating grate 5 corresponding to the side;
The fixed plate 8 is adjacent to the rotating shaft 9 and is positioned in the middle of the lower part of the hearth.
When in use, because the coke has good combustion performance and can be fully combusted in a short time, the coke is firstly added on the fixed grate 4, after the coke is fully combusted, the fire coal is added on the rotary grate 5, and in the combustion process of the fire coal, as shown in figure 2, part of the fire coal on the rotary grate 5 can be poured on the fully combusted coke by rotating the rotary grate 5, so that the combustion of the fire coal is accelerated, and through the action, the gap between the fire coal can be increased, thereby achieving the purposes of improving the full combustion rate of the fire coal and reducing the black smoke emission and polluting the environment on the whole.
In the high-efficiency coal-fired furnace, the height of the supporting plate 10 from the bottom surface of the furnace body 1 is not more than the height of the rotating shaft 9 from the bottom surface of the furnace body 1.
In the high-efficiency coal-fired furnace, the fixed fire grate 4 is obliquely arranged.
in the high-efficiency coal-fired furnace, a furnace body 1 corresponding to a rotary grate 5 is provided with a coal inlet 6, and a furnace body 1 corresponding to a fixed grate 4 is provided with a carbon inlet 7.
In the high-efficiency coal-fired furnace, the chimney 11 is positioned at the top of the furnace body 1 right above the fixed grate 4, because the combustion performance of the coal-fired is inferior to that of coke, black smoke generated before the coal-fired combustion is not fully combusted needs to be discharged through the chimney 11 right above the fixed grate 4, and in the discharging process, combustible parts in the black smoke are fully combusted in a high-temperature area generated by the full combustion of the coke, so that the full combustion rate of the coal-fired is further improved.
In the high-efficiency coal-fired furnace, one end of the rotating shaft 9 extends out of the furnace body 1, the end part is connected with a driving unit for driving the rotating shaft 9 to rotate, and the driving unit can be a crank or a connecting rod structure.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
