Description

Sidewall for incinerator and its installation structure {SIDE-WALL FIRE GRATE FOR INCINERATIOR AND INSTALLATION STRUCTURE STRUCTURE THEREOF}

The present invention relates to a grate for an incinerator, and in particular, to a sidewall grate installed facing the sidewall of the incinerator and its installation structure.

In general, waste such as household or industrial waste is incinerated using a stocker type incinerator. 1 shows the installation structure of a grate row in a conventional stocker type incinerator.

1, a plurality of heat-resistant/wear-resistant metal grate (10, 20) is supported by a round bar-shaped support bar (30M, 30S) to form one row, and such a grate row is a fixed end (F). And the moving end (M) are separated and alternately arranged in a stepped manner. In this case, in order to prevent the fire bricks on the inner wall of the incinerator from being damaged due to abrasion or adhesion of combustion by-products such as clinker, the sidewall grate 20 having a structure capable of covering a part of the inner wall of the incinerator (hereinafter , Abbreviated as'sidewall') is mounted on the outermost side of the fixed end (F).

When the trash movement direction is the front and the side to which the trash is put in the rear, the side wall 20 is mounted on the rear upper end of the front side wall 20 with the front lower end of the rear side wall 20 installed. do. At the fixed end, the front end of the sidewall 20 is disposed in front of the front end of the adjacent grate 10. The position where the fixed end support bar 30S is coupled is the rear lower end of the sidewall 20, which is placed on an extension line in the direct downward direction from the position where the front lower end of the rear sidewall 20 is mounted. 20) This prevents the support rod (30S) from rotating and prevents the accumulated load. In this case, since the stroke distance (b) of the moving end corresponding to the length of the grate 10 is smaller than the distance (Ds) between the fixed end round bars, in order to have the installation structure mounted between the side walls 20 as described above, the side wall The total length of (20) should be the same as the distance (a) between the fixed end round bars. Accordingly, both sides are supported between the inner wall of the incinerator and the fixed end grate 10 as long as (b) toward the rear of the side wall 20 while the side wall 20 is installed, but toward the front of the side wall 20 (Ds-b ) The part'A' corresponding to the length is exposed as it is in a bare state without support from the fixed-end grate or the moving-end grate in the process of operation to the side in the direction toward the inside of the incinerator.

In this case, since the portion'A' corresponding to the length of the sidewall (Ds-b) is exposed to the side of the incinerator as it is, the incinerator interior direction or vice versa due to repeated thermal stress when the incinerator is operated. It may be accompanied by a deformation that is twisted or curled toward the inner wall of the movable end grate 10, and this deformation interferes with the front and rear stroke of the moving end grate 10 or causes a problem that the deformed sidewall 20 or the moving end grate 10 collide with each other and fall out. can do. Alternatively, the extra length'A' as much as the front side (Ds-b) of the sidewall 20 does not actually contribute significantly to the protection of the inner wall of the incinerator, which prevents clinker adhesion compared to the increase in casting production cost because clinker adhesion is insignificant. Also, in general, the entire incineration stage is composed of a drying stage, a combustion stage, and a post-burning stage, and the boundary of each incineration stage is composed of a so-called drop-off stage (K) using fire bricks. In this case, the falling stage (K The length of) is also increased as much as the extra length (ab) in front of the sidewall 20, which increases the total construction cost of the incinerator. In addition, the refractory brick falling end (K), which is a fixed end, and the sidewall 20 installed in the same row must be substantially aligned in front of each other, and the corresponding incineration end according to the length of each of the drying end, combustion end and post combustion end Since the length of the fall cut end (K) of the incineration end is also different, there is an inconvenience of having to separately manufacture the sidewall by different specifications for each drop cut end of each incineration end.

In addition, since the conventional side wall 20 is a method in which the front lower end of the rear side wall 20 is simply mounted on the rear upper end of the front side wall 20, the mounting state can be easily separated when the side wall 20 is twisted. There is a problem that can be, and in order to reduce material cost, the weight 22 is processed toward the side facing the inner wall of the incinerator, but rather this may cause confusion in the installation work.

The present invention is to provide a sidewall grate for an incinerator and an installation structure thereof that is prevented from being deformed or dropped in the installation state, reduces manufacturing and installation costs, and is easy to install.

In the process of developing the sidewall grate for the incinerator and its installation structure related to the problem, the present inventors form an intermediate leg for coupling a fixed end support bar at an intermediate position under the sidewall, and rearward from the intermediate leg By providing an extension part in the entire length direction of the sidewall, by providing an installation structure that can be supported on one side by an inner wall of the incinerator and the other by a grate on the other side, deformation or dropping of the sidewall is prevented while manufacturing and installation costs are reduced. I thought it could be. In addition, the present inventors, etc., optionally, the fixed end support rod as a square rod, and correspondingly, the groove portion of the support rod coupling portion provided in the middle portion of the side wall has a cross-sectional shape of the square rod, so that the side wall is supported by the cumulative load when forming the intermediate portion. It is possible to reduce the possibility of rotating with the rotating shaft, and by providing a convex portion at the rear upper end of the sidewall so as to be coupled to it in an installed state while having a recess in each part in front of the sidewall, it is possible to firmly mediate the mounting between the front and rear sidewalls. In addition, it was conceived that confusion during installation could be prevented by allowing both sides of the sidewall grate to be installed on either side of the left and right side walls of the incinerator. The present invention was made by further embodiing the mechanical design based on such an idea, and the subject matter of the present invention based on the above-described problem and the idea is the same as described in the claims.

Hereinafter, the present invention will be described in detail through examples. Prior to this, terms or words used in the present specification and claims should not be construed as being limited to their usual or dictionary meanings, and the designer appropriately explains the concept of terms in order to explain his own design in the best way. Based on the principle that it can be defined, it should be interpreted as a meaning and concept consistent with the technical idea of the present invention. Therefore, the configuration of the embodiments described in the present specification is only one of the most preferred embodiments of the present invention, and does not represent all the technical ideas of the present invention, and various equivalents that can replace them at the time of filing of the present invention It is to be understood that there may be variations and variations. On the other hand, in the drawings, the same or similar reference numbers are given to the same or equivalent material, and in the entire specification, when a certain part "includes" a certain component, this is another component unless otherwise stated. It does not mean that other components may be further included.

Hereinafter, for convenience of explanation, with respect to the shape or installation orientation of the sidewall 50 grate and its respective parts, the lower part of the stairs is forward and the upper part is rear based on the direction in which waste (not shown) moves along the grate column stairs. Let's explain it. In addition, for the convenience of description and description, the'side wall 50 grate' is abbreviated as'side wall 50', and simply'grate 40' is installed adjacent to the'side wall 50 grate'. It may be a grate 40 forming a fixed end (F) or a grate 40 forming a moving end (M) between the fixed ends (F).

FIG. 2 is a perspective view of a sidewall 50 according to an embodiment of the present invention, FIG. 3 is a side view of the installation structure of the sidewall 50 row of FIG. 2, and FIG. 4 is the installation structure of the sidewall 50 row of FIG. It shows a side view of the operation according to each.

2, the side wall 50 is made of a plate-shaped body 52, and an intermediate leg 54 for coupling the fixed end (F) support bar 60 is provided at an intermediate position below the body 52 do. The body 52 is divided into a front portion and a rear portion based on the intermediate leg portion 54, and a portion extending rearward from the intermediate leg portion 54 is recognized as a rear extension portion 58. 3, this sidewall 50 is applied to a stocker-type incinerator in which a plurality of grate 40 rows are divided into a fixed end (F) and a moving end (M) and alternately arranged in a stepwise manner, and the fixed It is installed facing the inner wall of the incinerator from the outermost side of the stage (F).

3 and 4, in the installed state of the sidewall 50 row according to the present invention, the distance Ds between the fixed end (F) support rods 60; 60S corresponds to the total length of the sidewall 50 The total length of the sidewall 50 is a value obtained by adding the length (Ds-b') of the rear extension portion 58 to the distance b'from the front side of the sidewall 50 to the intermediate leg portion 54. In this case, the distance b'from the front side of the sidewall 50 to the intermediate leg portion 54 is equal to the total length of the adjacent grate 40. In this case, unlike the conventional fixed end of FIG. 1, the front end of the sidewall 50 in the fixed end F of the present invention coincides with the front end of the adjacent grate 40. In addition, the stroke distance of the grate 40 at the moving end (M) is slightly shorter than the distance (Ds) between the fixed end (F) and the support rods 60, but generally coincides with this. Accordingly, one side of the sidewall 50 and the body 52 from the front to the intermediate leg portion 54 is supported by the inner wall of the incinerator and the other side by the fixed end (F) grate 40. On the other hand, in a portion of the side wall 50 and the body 52 corresponding to the rear extension 58, one side is supported by sliding contact with the moving end (M) grate 40 by the inner wall of the incinerator.

In this installation structure, since both side walls 524 in the entire length of the side wall 50 and the body 52 can be supported by the inner wall of the incinerator and the grate 40, some of the side walls 50 as in FIG. Since both sides are not supported in'A', the problem of damage and dropout due to thermal deformation during operation can be effectively prevented. In addition, as the front length of the conventional sidewall 50 increases unnecessarily regardless of clinker prevention, the manufacturing cost of the sidewall 50 increases, and the falling end of the corresponding incineration end according to the length of each of the drying end, combustion end, and post combustion end (K) Since the length is also different, it is possible to avoid the hassle of having to separately manufacture by varying the specification for the length of the sidewall 50 for each falling end (K) of each incineration end.

According to an embodiment of the present invention, it is preferable that the coupling portion of the support rods 60 and 60M provided on the intermediate leg portion 54 is formed with a groove portion 542 that matches the cross-sectional shape of the corner rods 60M and 60S. In order to cover all the inner walls of the incinerator corresponding to the total length of the incinerator in the minimum number using the sidewalls 50 of FIG. 2, the front lower end of the rear sidewall 50 is similar to the conventional sidewall installation structure of FIG. It is a structure that is supported on the rear upper end of the front sidewall 50. In this case, the position where the support bar 60 supports each sidewall 50 is made at the middle leg portion 54 of the sidewall 50, but the rear of each sidewall 50 is other By receiving a load in the form of being pressed by the side wall 50, each side wall 50 has a tendency to rotate using the support bar 60 as a rotation axis. In this case, the rotation of the sidewall 50 and the likelihood of dropping out accordingly, the support rod 60 coupling portion provided on the intermediate leg portion 54 is formed of a groove portion 542 that matches the cross-sectional shape of the respective rods 60M, 60S. Can be prevented by

According to an embodiment of the present invention, in the structure in which the front lower end of the front sidewall 50 is supported on the rear upper end of the front sidewall 50, a convex portion 582 at the rear upper end of the sidewall 50 And, in the installed state, the concave portion 562 is provided at the front lower end of the side wall 50 so as to be coupled to the convex portion 582 of the front side wall 50. By firmly mediating the mounting between the front and rear sidewalls 50 by the combination of the concave portion 562 and the convex portion 582, the vibration transmitted during the front and rear sliding operation of the moving end (M) grate 40 or trash can be stepped. In spite of the drop impact transmitted in the process of sequentially moving along the incineration end, the dropout or departure of the mounted state between the sidewalls 50 may be suppressed or prevented.

In this case, the concave portion 562 may be provided on the front leg portion 56 provided in front of the sidewall 50. The entire sidewall 50 sufficient to cover the inner wall of the incinerator while reducing material cost by minimizing the height of the upper body 52 of the sidewall 50 excluding them by the formation of the front leg 56 and the intermediate leg 54 Height can be secured. In the installed state, the front leg portion 56 and the intermediate leg portion 54 are positioned below the incineration end formed by the fixed end grate 40, and sidewalls excluding the front leg portion 56 and the intermediate leg portion 54 ( 50) The upper body 52 is exposed above the fixed end (F) grate 40, and the rear extension 58 of the upper body 52 of the exposed sidewall 50 is per sliding as described above. One side is supported by the contacting moving end (M) grate 40. In addition, despite the drawings, positions where the concave portion 562 and the convex portion 582 are formed may be opposite to each other. For example, the concave portion 562 may be formed at the rear upper end of the sidewall 50, and the convex portion 582 may be formed at the front lower end or the front leg portion 56 of the sidewall 50.

Meanwhile, the front upper end of the sidewall 50 is processed to have a downwardly inclined portion 5222. The downwardly inclined portion 5222 minimizes the material cost in front of the sidewall 50 to the extent that it does not impede the inherent function of the sidewall 50 of preventing clinker adhesion to the inner wall of the incinerator, while the sidewall 50 Of the upper wall 522, the clinker, which may accumulate in front of the upper wall 522, can be easily separated by the front and rear motion of the grate 40 of the moving end M and can be moved forward.

In addition, the side wall 50 according to the embodiment of the present paper is manufactured in a plate shape, but both side walls 524 are formed symmetrically in a simple planar shape. That is, unlike the sidewall 50 according to the related art, the side wall facing the inner wall of the incinerator is not subjected to weight loss 22, but is processed into a simple flat shape. Accordingly, when the sidewall 50 is installed, the incinerator Since it can be constructed with the same sidewall 50 on either side of the left and right side walls, confusion can be avoided during the installation work.

As described above, according to the side wall 50 for the incinerator and its installation structure of the present invention, the intermediate leg 54 for coupling the fixed end (F) support rod 60 is formed at an intermediate position below the side wall 50, and By providing a rear extension 58 toward the rear from the intermediate leg portion 54, one side of the sidewall 50 is provided with an installation structure that can be supported by the inner wall of the incinerator and the other side by the grate 40. By doing so, deformation or dropping of the sidewall 50 in the installation state can be prevented, and manufacturing and installation costs can be reduced. In addition, the fixed end (F) support bar 60 is used as a leg bar (60M, 60S), and correspondingly, the groove portion 542 of the support bar 60 coupling portion provided in the middle leg portion 54 of the side wall 50 is inserted into the leg bar 60M, The cross-sectional shape of 60S) can reduce the possibility that the sidewall 50 rotates the support bar 60 toward the rotational axis due to the cumulative load when the intermediate leg portion 54 is formed, and the front leg portion 56 of the sidewall 50 The convex portion 582 is provided at the rear upper end of the sidewall 50 so as to be coupled to the concave portion 562 in the installed state, so that the mounting between the front and rear sidewalls 50 can be firmly mediated. In addition, confusion during installation can be prevented by making both sides of the sidewall 50 a simple plane symmetrical shape so that it can be installed on either side of the left and right side walls of the incinerator.
