Abstract

The utility model relates to a wind-cooling rolling fire grate which solves the prior problem that the rollers and the supporting plate of a former rolling fire grate are subject to burning out. The base of the utility model is provided with a plurality of rollers whose one ends are provided with a ratchet wheel pawl mechanism of and an air exhausting mechanism, and the other ends are provided with an air regulating device. The rollers are driven to rotate by the ratchet wheel pawl. The utility model has the advantages of strong capability of coke breaking, no leakage of coal and long service life.

Description

Wind-cooling rolling fire grate
The utility model belongs to a kind of combustion apparatus, particularly a kind of air-cooled rolling fire grate.Fire grate is the chief component of boiler, mainly contain traveling-grate stoker, reciprocal grate and rolling fire grate in the prior art, chain fire-gate characteristics are stable, but do not possess broken burnt ability, though reciprocal grate has certain broken burnt ability, but it is more serious to leak coal, moreover when coking was serious, reciprocal grate was also powerless.Patent Office of the People's Republic of China disclosed once that a kind of application number is 89208426, the energy-efficient rolling fire grate of x, this fire grate is to adopt some cylinders to carry coal, but this fire grate fails fully to solve the cooling problem, particularly in the short time of blowing out just, because air blast and air inducing all closes, but temperature is still very high in the stove, so cylinder and following supporting plate are easy to be burnt out, finally cause influencing the normal operation of boiler.
The purpose of this utility model is to overcome weak point of the prior art, provides a kind of broken burnt ability strong, does not leak coal, the air-cooled rolling fire grate of cool off, the life-span is long.
The utility model is achieved in that it has a base, and some rollers are installed on base, and supporting plate is installed below roller; Left end at roller all is equipped with the air draft plate, at right-hand member air regulating board is installed all, with pull bar that reductor is connected on be welded with and the same number of lever of cylinder, lasso and ratchet are installed on lever.
Advantage of the present utility model is broken that burnt ability is strong, does not leak coal, long service life.
Fig. 1 is a front view of the present utility model;
Fig. 2 is an A-A cutaway view of the present utility model;
Fig. 3 is the partial enlarged drawing at the I place of the utility model Fig. 2;
Fig. 4 is the B-B cutaway view of the utility model Fig. 1.
Describe in detail below in conjunction with accompanying drawing.
The utility model is by a base of being made up of left bellows 1, right bellows 14 and dividing plate 4, on the side plate 14B of the side plate 1A of left bellows 1 and right bellows 14, be processed with the corresponding hole of a row respectively, cylinder 6 is installed in the hole, for ease of transmission, also by bearing pin roller 15 is installed around the hole of said side plate 1A and side plate 14B, said cylinder 6 is placed on the roller 15 after passing the hole.Be cast with brokenly the convex tendon of burnt usefulness at the outer surface of said cylinder 6, on barrel, be processed with the air vent 6A of ventilation usefulness, but do not process air vent on two the cylinder in two of front ends and rear end.Also be respectively installed with sealing ring 8 and the gland 10 that seals at cylinder 6 two ends, be placed with asbestos cord 7 between sealing ring 8 and gland 10, said gland 10 and sealing ring 8 usefulness bolts are separately fixed on side plate 1A and the 14B.Be processed with internal thread and by the ratchet 17 that has been threaded at the left end of said cylinder 6; After the pull bar 3 that is connected with reductor 28 extend in the left bellows 1, on pull bar 3, be welded with and the same number of lever 2 of cylinder, on lever 2, ratchet 25 is installed by bearing pin, one end of ratchet 25 is connected with a spring 26, the other end of spring 26 is fixed on the lever 2, be welded with a lasso 24 in lever 2 upper ends, on lasso 24, be processed with two hole 24A and 24B, be welded with a stile 19 in the upper end of lasso 24, on said stile 19, a ratchet 18 is installed by bearing pin, for preventing that lasso 24 from skidding off, right-hand member at each lasso also is equipped with the location-plate 16 of locating usefulness by screw, and said ratchet 25 and ratchet 18 are respectively by the hole 24A on the lasso and 24B and ratchet 17 engagements.On the side plate 1B of left bellows 1, be welded with and cylinder 6 corresponding sleeve pipes 21, an air draft wrench handle 22 all is installed in each sleeve pipe 21, end at air draft wrench handle 22 all is equipped with an air draft plate 20 by bearing pin, and said air draft plate 20 withstands on ratchet 17 inwalls that connect as one with cylinder 6; The spring 23 of the usefulness that resets also is installed on said air draft wrench handle 22.On the side plate 14A of right bellows 14, be processed with and cylinder 6 corresponding holes, in the hole, be welded with guide pipe 13, a rotating shaft 12 is installed in guide pipe 13, in rotating shaft, be set with a back-moving spring 11, one end of rotating shaft 12 is welded with an air regulating board 9, and said air regulating board 9 withstands on the right side of cylinder 6.On the side plate 14B of right bellows 14, also be processed with an air vent 27.
During use, the bellows 14 on right side are communicated with air blast, and the bellows 1 in left side are connected by fairlead and burner hearth, and pull bar 3 drives lever 2 under the effect of reductor reciprocating, at this moment the ratchet 24 that is installed on the lever 2 is promptly stirred ratchet 17 rotations, and the effect of ratchet 18 is to prevent ratchet 17 revolutions.When cold air is entered right bellows 14 by air blast after, hole 27 from side plate 14B directly enters burner hearth, can control the air quantity that enters in the cylinder 6 by regulating air regulating board 9, a part of wind be entered in the cylinder 6 and by the air vent 6A on cylinder 6 barrels enter above the fire grate, be beneficial to burning of coal.Can earlier reductor cut out during blowing out, make the cylinder stall, spur air draft wrench handle 22 then, the air draft plate 20 that withstands on the ratchet 17 is opened, at this moment cold wind arrives left bellows 1 from right bellows 14 through cylinders 6 are inner, guides to burner hearth from left bellows 1 by fairlead then.Can guarantee like this cylinder can be after blowing out cooling gradually, prevent that cylinder and supporting plate from being burnt out.
