Abstract
The utility model discloses a boiler grate and belongs to the technical field of boilers. The boiler grate comprises grate bars; every grate bar comprises an upper plate and lateral plates, wherein the lower end of the upper plate is surrounded by the lateral plates; through holes are vertically formed in every upper plate, wherein the diameter of the upper end of the through holes is smaller than that of the lower end of the through holes; the opening ratio of the upper plates is 3.1%. According to the boiler grate, the grate bars are provided with the through holes, the diameter of the upper end of the through holes is smaller than that of the lower end of the through holes, and accordingly air supply and sand leakage can be performed simultaneously in the bagasse burning process, silt can be discharged timely, the through holes of the grate are not blocked, the normal work of a boiler is ensured, and accordingly bagasse of natural resources is reasonably utilized to serve as fuel of the boiler and the economic efficiency and the reliability of the boiler can be improved.
Description
Technical field
The utility model relates to boiler technology field, especially a kind of boiler grate using bagasse as fuel wood.
Background technology
Boiler is a kind of energy conversion; Have the fuel of heat energy to boiler input, through boiler conversion, outside output has steam, high-temperature water or the organic heat carrier of certain heat energy and produces and living needs for people.Its fuel is mainly coal, and the flue gas dust concentration of not only discharging as fuel with coal is high, and flue gas blackness is large, and environment is caused to severe contamination, and along with the minimizing day by day of coal resource, causes production cost more and more higher; There is wide cane planting ground in China, squeeze the bagasse after sugar, can be used as the fuel of boiler, but because bagasse itself carries the silt while getting back from ground, when burning, can make boiler grate hole plug, fire grate hole plug gas does not circulate and will cause the increase of boiler internal pressure, finally cause the blast of boiler, so how to transform boiler pot row, rationally utilize the bagasse of natural resources as the fuel of boiler, can improve again economy and the reliability of boiler, be people's new problems anxious to be resolved.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of boiler grate, and this boiler grate can solve the fire grate hole plug of boiler grate, causes the bursting of boilers, causes the problem of personal injury and device damage.
In order to address the above problem, the technical scheme that the utility model adopts is: this boiler grate, include fire grate segment, described fire grate segment has upper plate and mutually encloses in the side plate of upper plate lower end, on described upper plate, evenly vertically offer up-small and down-big through hole, the percent opening of described upper plate is 3.1%.
In the technical scheme of above-mentioned boiler grate, technical scheme can also be more specifically: described through hole is round tube hole, and the upper-end inner diameter of described through hole is 14mm, and described through hole bottom diameter is 16mm.
Further: described upper plate center offers the through hole that installs fixture, the length of described upper plate is 310mm, and width is 298mm, and thickness is 20mm.
Further: described upper plate is square or rectangular.
Owing to having adopted technique scheme, the utility model compared with prior art has following beneficial effect:
1, the utility model had both rationally utilized the bagasse of natural resources as the fuel of boiler, can improve again economy and the reliability of boiler.
2, the through hole on the utility model fire grate segment, in the process of bagasse burning, air feed and leakage sand are taken into account, and in time silt are leaked and are removed, and do not stop up fire grate through hole, have ensured the normal work of boiler.

Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is Figure 1A-A place cutaway view.
Fig. 3 is Fig. 2 B-B place cutaway view.
Fig. 4 is I place enlarged drawing in Fig. 2.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail:
Embodiment mono-
A kind of boiler grate, includes fire grate segment, and the fire grate segment shown in Fig. 1, Fig. 2, Fig. 3 has upper plate 1 and mutually encloses the side plate 2 in upper plate lower end, and upper plate 1 is rectangle, and the length of upper plate 1 is 310mm, and width is 298mm, and thickness is 20mm; On upper plate 1, vertically offer up-small and down-big through hole 1-1, the percent opening of upper plate is 3.1%; Through hole 1-1 is round tube hole and is uniformly distributed on upper plate, and the upper-end inner diameter of through hole 1-1 is 14mm, and through hole 1-1 bottom diameter is 16mm; Upper plate 1 center also offers and installs the through hole 1-2 that fixture is the screw thread of bolt.
Embodiment bis-
Upper plate 1 is square; The length of side is 310 mm, and all the other are all identical with embodiment mono-.
On the utility model fire grate segment, offer up-small and down-big through hole, in the process of bagasse burning, air feed and leakage sand are taken into account, and in time silt are leaked and are removed, and do not stop up fire grate through hole, have ensured the normal work of boiler.Both rationally utilize the bagasse of natural resources as the fuel of boiler, and can improve again economy and the reliability of boiler.
