Abstract

The utility model discloses a multifunctional flame bridge for big-flame two-purpose air-return stoves, and is composed of a main flame bridge and an auxiliary flame bridge. Main flame bridge teeth (8) are equispaced in the frame of the main flame bridge (4). Auxiliary flame bridge teeth (9) are symmetrically arranged at both sides of a rotation shaft (3) for forming the auxiliary flame bridge (5). The auxiliary flame bridge (5) is arranged in the main flame bridge (4), and the auxiliary flame bridge teeth (9) are respectively inserted between two main flame bridge teeth (8) in the main flame bridge (4). The utility model has a compact structure, and can simultaneously satisfy the burning use of honey-comb coals, block coals and coalball. If poking fire is needed, when the honey-comb coals are burnt, the rotation shaft (3) is just needed rotating, and auxiliary flame bridge (5) can make the burnt honey-comb coal broken into pieces. The broken slag can drop in an ash box through a seam of the main flame bridge. If the block coals and the coalball are burnt, the flame bridge is equal to a common stationary flame bridge. The rotation shaft (3) on the auxiliary flame bridge (5) can not only rotate, but also move coal ash along the shaft line, and is suitable for various air-return stoves.

Description

The prosperous two-used air return stove multifunctional fire grating of duration and degree of heating

Technical field: the utility model relates to the air return stove grate, the prosperous two-used air return stove multifunctional fire grating of particularly a kind of duration and degree of heating.

Background technology: two-used air return stove grate of the prior art is that circular arc and straight-bar intersect and be installed in the rotating shaft, when burning honeycomb briquette, straight-bar horizontal positioned on the grate, honeycomb briquette places on the straight-bar, when first honeycomb briquette has burnt need disclose fire the time, clockwise rotate rotating shaft, rotating shaft drives the grate upset, grate ploughs under first honeycomb briquette in the ash bin, and the circular arc in this process on the grate withstands second honeycomb briquette, rotates counterclockwise rotating shaft then, straight-bar on the grate is horizontal, second honeycomb briquette drops on the straight-bar of grate, like this, just finished one and disclosed fiery coal process.When needs burn lump coal or coal briquette, clockwise rotate rotating shaft 90 degree, the circular arc on the grate is forwarded below the combustion chamber to this grate following points deficiency:

1. the upper end of first honeycomb briquette can not be higher than the combustion chamber lower end, otherwise, when upset, the upper end of honeycomb briquette will be blocked by combustion chamber, and therefore, first honeycomb briquette burns outside burner hearth fully, burning is not so good as in being jealous of thorax abundant certainly, spread heat, and the utilization rate of heat energy is low.

2. because the circular arc on first honeycomb briquette and the grate occupies very big bulk, so that the base of air return stove must be done is very high.

3. when burning lump coal or coal briquette, if the grate arc swing is excessive, unburned coal just might drop in the ash bin.

Summary of the invention: the purpose of this utility model is: provide a kind of duration and degree of heating prosperous two-used air return stove multifunctional fire grating, this grate is made of main grate and secondary grate, not only honeycomb briquette can be burnt but also lump coal and coal briquette can be burnt, it only needs rotating shaft, the honeycomb briquette that secondary grate just can will burn is smashed, and the lump coal that burns and coal briquette are bled in the ash bin.

Formation of the present utility model: form by main grate and secondary grate, uniform main furnace grate tooth 8 in main grate 4 frames, be symmetrical arranged secondary furnace grate tooth 9 on the both sides of rotating shaft 3 and form secondary grate 5, secondary grate 5 places in the main grate 4, and secondary furnace grate tooth 9 inserts respectively between two main furnace grate tooths 8 in the main grate 4.

Secondary furnace grate tooth 9 on the secondary grate 5 can be one, also can be a plurality of.

Compared with the prior art, the utility model is made up of main grate and secondary grate, this grate compact conformation, can satisfy burning honeycomb briquette, lump coal or coal briquette simultaneously uses, when burning honeycomb briquette such as need disclose fire, only need rotating shaft, secondary grate can be smashed the honeycomb briquette that has burnt, and this disintegrating slag can be dropped in the ash bin by main grate seam.As burn lump coal or coal briquette, and this grate is the same with common fixed grate, and the rotating shaft on the secondary grate was both rotatable, also can move down coal ash along axis.

Description of drawings: Fig. 1 is the utility model structural representation.Fig. 2 is the A-A cutaway view of Fig. 1.

1. stove buckets among the figure, 2. combustion chamber, 3. rotating shaft, 4. main grate, 5. secondary grate, 6. ash bin, 7. honeycomb briquette, 8. main furnace grate tooth, 9. secondary furnace grate tooth.

The specific embodiment: as shown in Figure 1 and Figure 2, combustion chamber 2 is installed in stove bucket 1, grate 4 and secondary grate 5 are installed below combustion chamber 2, on grate, place honeycomb briquette 7, uniform main furnace grate tooth 8 in main grate 4 frames, be symmetrical arranged secondary furnace grate tooth 9 on the both sides of rotating shaft 3 and form secondary grate 5, secondary grate 5 places in the main grate 4, secondary furnace grate tooth 9 inserts respectively between two main furnace grate tooths 8 in the main grate 4, secondary furnace grate tooth 9 on the secondary grate 5 can be one, also can be a plurality of, rotating shaft 3 drives secondary furnace grate tooth 9 and can rotate, and also can move along axis.Ash bin 6 is arranged below grate.

Claims

1. prosperous two-used air return stove multifunctional fire grating of duration and degree of heating, form by main grate and secondary grate, it is characterized in that: uniform main furnace grate tooth (8) in main grate (4) frame, be symmetrical arranged secondary furnace grate tooth (9) on the both sides of rotating shaft (3) and form secondary grate (5), secondary grate (5) places in the main grate (4), and secondary furnace grate tooth (9) inserts respectively between interior two main furnace grate tooths (8) of main grate (4).

2. the prosperous two-used air return stove multifunctional fire grating of duration and degree of heating according to claim 1 is characterized in that: the secondary furnace grate tooth (9) on the secondary grate (5) can be one, also can be a plurality of.
