Abstract
The present invention discloses a grate for an incinerator. More particularly, the present invention relates to a grate for an incinerator, which transports various kinds of incineration products such as industrial and environmental wastes to be incinerated into the incinerator efficiently.
According to the embodiment of the present invention, it is possible to provide a grate that does not detach from the ring rod even when an external force is applied to the grate, by extending a part of the rear end coupled with the ring rope longer than the thickness of the ring rope.
Description
BACKGROUND OF THE
In general, the incinerator is classified into a stoker combustion system, a rotary furnace combustion system, and a fluidized combustion system, and such a combustion system is selected depending on the type and the throughput of incineration materials to be treated. In particular, the stocker combustion method is mainly used for large - scale incineration of urban incinerators.

The present invention has been conceived to solve the above-mentioned problems, and it is an object of the present invention to provide a grate for use in an incinerator or the like, in which each grate is not separated from a support rod without providing any supplementary means, There is a problem in providing a durable grate that does not easily break even with an external force.
In order to solve the above-mentioned problems, a grate according to an embodiment of the present invention is a grate having a plurality of steps arranged in a staggered fashion, the grate having an upper end where an incineration water is located; A front end portion extending from one side of the upper end portion; Side ends formed in the vertical direction on both sides of the upper end to form an inner space and the ribs being recessed to a predetermined depth; And a rear end portion which is formed to face the front end portion with respect to the inner space and which is coupled to surround the support rod with a lower portion thereof being opened, wherein the rear end portion includes a protrusion extending at least the thickness of the support rod .
The rear end portion may be a reverse U shape and at least one protrusion may be hemispherically arranged in an inner direction of the outermost end.
The upper end may be provided with a first lug having a stepped section with a lower surface.
The front end may have a second lug on its surface.
The first and second lugs may be integrally formed with the lower surface and the front end, respectively.
The opposite end portions may be formed at a point where they meet with the upper end portion, and at least one linear groove may be formed on both side surfaces, each of which is longitudinally parallel to the ribs.
The grate according to the embodiment of the present invention has an effect that a part of the rear end portion coupled with the rope is elongated longer than the thickness of the rope so that the grate can not be detached from the rope even if an external force is applied to the grate.
Further, the grate according to the embodiment of the present invention has the effect of minimizing breakage due to external force and prolonging the life span by further providing reinforcement portions in the inner space and the front end portion.
FIG. 1 illustrates a conventional stoker combustion type grate.

3 is a perspective view of a grate viewed from a bottom direction according to an embodiment of the present invention.
4A to 4E are a side view, a bottom view, a rear view, a front view, and a sectional view of a grate according to an embodiment of the present invention.
Prior to the description, when an element is referred to as being "comprising" or "including" an element throughout the specification, it is to be understood that the element may be further comprised of other elements . Furthermore, terms such as " part, "" unit," or "unit, ", etc. in the specification may refer to components having independent functions by at least one or two or more combinations.
In addition, the thickness of the lines and the size of the constituent elements shown in the drawings may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are defined in consideration of the functions of the present invention, which may vary depending on the intention or custom of the user, the operator. Therefore, definitions of these terms should be made based on the contents throughout this specification.
Hereinafter, a grate for an incinerator according to a preferred embodiment of the present invention will be described with reference to the drawings. In the following description, the names of the constituent elements of one unit grate are based on the position of the incineration object and its moving direction.
