Abstract
The utility model discloses a large coal-leakage prevention reciprocating grate which comprises a plurality of fire grate segments (1) which are arranged side by side and coal pushing boards. The adjacent edges of adjacent fire grate segments (1) are overlapped, and the adjacent edges of adjacent coal pushing boards (2) are overlapped. In the reciprocating process, the reciprocating grate can effectively reduce gaps, reduce leaked coal and prevent coal waste. The wave-shaped edge design ensures that the air lines among the fire grate segments are elongated, the air distribution of the grate is broad, the combustion of coal is complete and the combustion efficiency is greatly improved.
Description
Technical field:
The utility model relates to a kind of coal-burning boiler reciprocal grate, especially a kind of large-scale coal reciprocal grate that do not leak of saving fire coal, improving efficiency of combustion.
Background technology:
Coal-burning boiler has traveling-grate stoker and two kinds of versions of reciprocal grate with fire grate, and coal-burning boiler is employed mostly in the past all is traveling-grate stoker, but traveling-grate stoker exists the demanding problem of coal quantity, promptly can not use colm.At present, along with the day of coal resources is becoming tight and coal price constantly surging, colm also begins to be used in a large number, and reciprocal grate that therefore can burning inferior coal just is subjected to the favor in market, and maximizes gradually.Existing reciprocal grate is made up of coal bunker, support, built-in beam, walking beam, fire grate segment, coal-pushing plate etc., fire grate segment wherein, coal-pushing plate have a plurality of and are arranged side by side, each adjacent fire grate segment, the coal-pushing plate that each is adjacent are vertical bar and access node structure, do not overlap mutually, fire grate segment, coal-pushing plate can produce bigger gap in reciprocating motion, to such an extent as to produce serious leakage coal phenomenon, cause coal-fired waste; In addition, existing reciprocal grate only has several wind lines in the fire bars front portion, and air intake surface is narrow, has influenced combustion efficiency, has reduced efficiency of combustion.
Summary of the invention:
The utility model is at the technical problem that the existing in prior technology fire coal is wasted, efficiency of combustion is low, and a kind of large-scale coal reciprocal grate that do not leak of saving fire coal, improving efficiency of combustion is provided.
Technical solution of the present utility model is: a kind of large-scale coal reciprocal grate that do not leak, a plurality of fire grate segments 1 and the coal-pushing plate 2 that are arranged side by side are arranged, and it is characterized in that: the adjacent side of adjacent fire grate segment 1 overlaps mutually, the adjacent side of adjacent coal-pushing plate 2 overlaps mutually.
The adjacent side undulate of described fire grate segment 1.
Be provided with seam 3 between the adjacent side of described coal-pushing plate 2.
The adjacent side overlap joint mouth of described fire grate segment 1 is a curves.
The adjacent side of the adjacent fire grate segment of the utility model, the adjacent side of adjacent coal-pushing plate are mutual bridging arrangement, in the reciprocating motion process, can dwindle the gap effectively, reduce to leak coal, prevent coal-fired waste; And corrugated adjacent side design can make the wind line between fire grate prolong, and makes the fire grate wind distributing face wide, and fired coal combustion is abundant, has greatly improved efficiency of combustion.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the structural representation of the utility model embodiment fire grate segment.
Fig. 3 is the A-A view of Fig. 2.
Fig. 4 is the structural representation of the utility model embodiment coal-pushing plate.
The specific embodiment:
Below in conjunction with the description of drawings specific embodiment of the present utility model.Basic structure of the present utility model is same as the prior art, promptly as shown in Figure 1, form by coal bunker 4, support 5, built-in beam 6, walking beam 7 and a plurality of fire grate segment that is arranged side by side 1, a plurality of coal-pushing plates that are arranged side by side 2 etc., with prior art different is wherein fire grate segment 1, coal-pushing plate 2 structures.
Fire grate segment 1 of the present utility model, coal-pushing plate 2 structures are shown in Fig. 3,4, and the adjacent side of adjacent fire grate segment 1 overlaps mutually, the adjacent side of adjacent coal-pushing plate 2 overlaps mutually.Fire grate segment 1 is preferably as shown in Figure 2: i.e. adjacent side undulate.In order to improve the overlap joint effect better, be provided with seam 3 between the adjacent side of described coal-pushing plate 2, the adjacent side overlap joint mouth of described fire grate segment 1 is the curves shape.Can effectively prevent the leak-stopping coal, save fire coal, improve efficiency of combustion.
Claims (4)
1. one kind large-scale does not leak the coal reciprocal grate, and a plurality of fire grate segments (1) and the coal-pushing plate (2) that are arranged side by side are arranged, and it is characterized in that: the adjacent side of adjacent fire grate segment (1) overlaps mutually, the adjacent side of adjacent coal-pushing plate (2) overlaps mutually.
2. the large-scale coal reciprocal grate that do not leak according to claim 1 is characterized in that: the adjacent side undulate of described fire grate segment (1).
3. according to claim 1 or the 2 described large-scale coal reciprocal grates that do not leak, it is characterized in that: be provided with seam (3) between the adjacent side of described coal-pushing plate (2).
4. the large-scale coal reciprocal grate that do not leak according to claim 3 is characterized in that: the adjacent side overlap joint mouth of described fire grate segment (1) is curves.
