Abstract

The side grate of the present invention causes wear together due to the operation of the movable shaft of the incinerator. However, even if the bed grate moves due to the operation of the actual movable shaft, the entire portion of the side grate is not worn out. That is, depending on the motion of the bed grate, wear occurs only in the second half of the side grate, and the front part 11 of the side grate, which is a part mounted on the fixed shaft, hardly wears. Therefore, the present invention is characterized in that the side grate 10 is divided into a front half 11 without wear and a back half 12 with a large wear.

Description

[0001] Side grate for incinerator and installation structure [

The present invention relates to a grate for an incinerator, and more particularly, to a grate for protecting the bottom and sidewalls of an incinerator, in which the construction and replacement work are facilitated by a divided grate, and only the worn portion of the grate is replaced Thereby reducing the maintenance cost of the grate.

Recently, household waste and industrial wastes are being discharged in large quantities due to an increase in consumer life. However, there is no economical and efficient way to deal with it. Particularly, as the recognition that the landfill which is generally used in the past is the main cause of soil pollution, the method of incinerating various kinds of waste by using incinerator is widely used.

Garbage incinerator is a furnace that separates and burns combustible garbage. In the past, a pyrotechnic furnace of refractory bricks was used. Recently, there is a tendency that a mechanized garbage incinerator is developed and automated .

Generally, an incinerator is composed of a charging port into which incineration water is injected, a combustion chamber in which a grate is provided, and a hopper which discharges the burnt residue. Here, the grate is a consumable structural component installed on the bottom of the combustion chamber in which the incineration water is burned. In order to increase the combustion efficiency of the incineration water continuously injected, the incineration water is transported stepwise from the inlet port to the lower part so that the oxygen supply is smoothly inverted . For this purpose, it consists of a grate mounted on a fixed shaft and a grate mounted on a movable shaft, so that the movement of the movable shaft as well as the movement of the grate allows smooth movement of the incineration water.

However, since the grate of Patent Document 1 shown in Fig. 1 is formed as a " b " shape, since the side plate and the bed plate are integrally formed, the weight is heavy and workers are hard to handle, There is a problem that the maintenance cost unreasonably increases.

The grate of Patent Document 2 shown in FIG. 2 is also provided with the side plate and the bed plate independently, and the side plate is plate-shaped and disposed between the side wall of the incinerator and the bed plate to protect the side wall of the incinerator. The side plate must be replaced after a certain use due to abrasion. Since the side plate and the bed plate are separately installed, the side plate or the bed plate can be individually replaced.

Nevertheless, the grate of Patent Document 2 still has the problem of replacing the side plate with the cylinder even though only a part of the side plate is worn.

Patent Document 1: JP-A-10-1054561 Patent Document 2: JP-A-10-1579973

Accordingly, it is an object of the present invention to minimize the assembly and replacement costs of the grate provided on the bottom and sidewalls of the incinerator, and to facilitate handling.

Specifically, the grate of the present invention is installed for the purpose of protecting the bottom and sidewalls of the incinerator, and it should be easy to handle due to transportation, assembling, disassembling and replacement work, and moreover, do.

The front and rear portions of the side grate are separated from each other by a supporting groove portion and a support portion. The side grating is divided into a front portion and a rear portion, And is coupled with the projection.

Preferably, the protruding support is provided on a side surface of the bed grate so as to be supported by an adjacent bed grate mounted on the fixing shaft so as to prevent sagging of a front portion and a rear portion of the side grate.

More preferably, the side grate is provided with support protrusions on the upper end portion of the rear half without wear and is provided with support grooves at the lower end of the worn front end portion, corresponding to the support protrusions or support grooves of the adjacent side grate And are combined with each other.

According to the present invention, in the side grating, it is possible to reduce the cost by dividing the portion having a high degree of abrasion and the portion having little abrasion according to the degree of abrasion wear and maintenance and repairing only the portion with a high wear, The labor intensity of the operator in the transportation and installation work can be remarkably reduced.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description, well-known functions or constructions are not described in detail to avoid unnecessarily obscuring the subject matter of the present invention.

1 and 2, the bed grate 21 and the side grate 10 are adjacent to each other to protect the bottom and side walls of the incinerator. The bed grate 21 is fixed The side gratings 10 are provided at both side ends of the fixed shaft, that is, adjacent to the side walls.

Particularly, they are laminated in a stepwise manner, and are alternately mounted on the fixed shaft 2 and the movable shaft 3. [ At this time, the side grate 10 is mounted on the fixed shaft 2 with a shaft fitting groove (not shown) for inserting the fixed shaft 2 into one end of the lower side, and the other end of the lower grate is fixed by the adjacent side grate Can be supported.

As shown in Fig. 3, the side grate 10 is worn together by the operation of the movable shaft 3 of the incinerator. However, even if the bed grate 20 moves due to the operation of the actual movable shaft 3, the entire portion of the side grate 10 is not worn. In other words, depending on the movement of the bed grate 20, wear occurs only in the rear half 12 of the side grate 10, and the front half 11 of the side grate, which is a portion mounted on the fixed shaft 2, I will not. Therefore, the present invention is characterized in that the side grate 10 is divided into a front half 11 without wear and a back half 12 with a large wear.

By dividing the front part 11 and the rear part 12 of the side gratings in this manner, it is possible to improve the point that the part without wear is replaced, and only the rear part 12 with a large wear can be selectively replaced, The strength of the work is weakened, and the fatigue of the worker can be remarkably improved.

It is preferable that the front and rear halves 11 and 12 of the side grate 10 are integrally joined to each other so as to be mounted on the stationary shaft 2. In order to engage the front half portion and the rear half portion, 121) is required. It is preferable that the engagement grooves 111 and the engagement protrusions 121 are provided at the portions where the first half 11 and the second half 12 of the side grate 10 are in contact with each other.
