Description

Detachable side wall grate for incinerator {Detachable side wall grate for incinerator}

The present invention relates to a sidewall grate for an incinerator, and more particularly, to a detachable sidewall grate for an incinerator.

Waste such as household or industrial waste is incinerated using an incinerator. In general, when garbage or waste is incinerated in an incinerator, non-combustible residues such as clinker are adsorbed on the fire wall. Normal operation of the grate cannot be expected.

The grate row of the incinerator is formed by a plurality of heat-resistant/abrasion-resistant metal grates supported by round rods to form one row. In this case, in order to prevent the refractory bricks of the inner wall of the incinerator from being worn or damaged due to adhesion of combustion by-products such as clinker, the side wall grate having a structure that can cover a part of the inner wall of the incinerator is the uppermost part of the fixed end. mounted on the outside

The fixed end is mounted on the fixed frame of the conveying device by the round bar for the fixed end, and the moving end is attached to the movable frame of the conveying device by the round rod for the moving end. It operates in such a way as to sequentially move the waste to the exit side while reciprocating back and forth between them. During the forward and backward reciprocation of the moving end, wear damage occurs at the contact portion between the lower end of the sidewall grate of the fixed end adjacent to the front and rear and the upper surface of the outermost grate of the moving end, as shown in FIG. 1, depending on the degree of wear (Fig. Refer to the red circle in 1) The sidewall (wall part) protrudes from its original position to the inside of the incinerator or begins to collapse, interfering with the operation of the grate. Therefore, maintenance such as periodic replacement is required for the damaged sidewall grate. need.

However, since the sidewall grate is very heavy, it is not easy to handle, such as transport and installation by workers inside the incinerator, and it is not economical because the entire grate must be replaced instead of only the damaged part.

Korean Patent Registration No. 1935814 discloses a sidewall grate, and Korean Patent Registration No. 1054561 discloses a grate structure for preventing clinker adhesion. As shown in FIG. 2, both inventions have integrated sidewalls as described above. Regarding the grate 10, it is impossible to partially replace it, and as a heavy object approaching 80 kg, handling is very difficult.

On the other hand, Korean Patent Registration No. 2065568 discloses a separate type sidewall grate in which the wall part and the body part are separated, but as shown in FIG. 3, the wall part 11 and the body part 12 are coupled in an annular coupling. Therefore, when the bearing capacity of the body part 12 supporting the wall part 11 is not sufficient, and in particular, when the contact part 13 between the top surfaces of the outermost grate of the moving end is abraded and damaged, the wall part 11 moves from its original position to the inside of the incinerator. The problem of obstructing the operation of the grate by protruding or collapsing is still unresolved.

The present invention is a detachable sidewall grate, which is easy to replace and has a structure in which only the worn part can be partially replaced, and the replacement period due to abrasion damage at the contact part between the upper surfaces of the outermost grate of the moving end can be extended. want to provide

The present invention in order to solve the above problems, the wall portion is installed facing the inner surface of the incinerator fire wall; and a body portion that is separated from the wall portion and supports the wall portion when combined with the wall portion, wherein the body portion has a T-shaped horizontal cross section for coupling with the wall portion on one side thereof. And a protrusion extending in the vertical direction is formed, and the wall portion provides a separate type sidewall grate in which the protrusion is fitted and a coupling groove extending in the vertical direction is formed.

In addition, the coupling groove provides a detachable sidewall grate, characterized in that formed longer than the height of the protrusion.

In addition, a horizontal protrusion is formed at the lower end of one side of the wall unit and a horizontal coupling groove is formed at the upper end of the other side to be fitted and coupled to the horizontal protrusion of any other wall unit, so that the split type sidewall grate is stacked in a stepwise manner by connecting the wall units to each other. It provides a detachable sidewall grate, characterized in that arranged.

According to the present invention, in the separate type sidewall grate in which the wall portion and the body portion are separated, the T-shaped protrusion formed on the body portion and the coupling groove formed on the wall portion are coupled to strengthen the bearing capacity of the body portion and the wall portion, and the height of the coupling groove By forming the protrusion to be longer than the height of the moving end, it is possible to naturally position the body downward in case of abrasion damage at the contact part between the uppermost grate grates. Accordingly, the durability of the sidewall grate can be remarkably increased by maintaining the L-shaped shape of the sidewall grate to maintain the bearing capacity of the body portion to the wall portion and extending the replacement period due to wear and tear.

In addition, horizontal protrusions and horizontal coupling grooves are formed in the wall portion to be chain-connected and installed in a stepwise manner, so that the wall portion itself has a reinforced bearing capacity so that it does not easily protrude or collapse, further increasing the durability of the sidewall grate.

The body part 120 is a grate located on the outermost side of the fixed grate row, and in the present invention, a protrusion 121 for coupling with the wall part 110 is formed on one side, that is, the side adjacent to the wall part 110. has been The protrusion 121 has a T-shaped horizontal cross section, is composed of a long width portion 121a and a short width portion 121b, extends in the vertical direction, and the height H1 of the protrusion 121 is equal to the body portion 120 is smaller than the height (H2) of At this time, the upper surface of the protruding part 121 is formed so as to be continuous with the upper surface of the body part 120, so that when the body part 120 is positioned downward due to abrasion of the body part 120 in terms of durability described later, the sidewall The period during which the L-shape of the grate 100 is maintained can be maximally extended.

The wall portion 110 is formed in a plate shape as a whole and is installed facing the fire wall to prevent the fire brick from being worn or damaged due to adhesion of combustion by-products such as clinker. In the present invention, the protrusion 121 Fitted and extending in the vertical direction coupling groove 111 is formed.

The short-width portion 121b of the protrusion 121 is fitted into the coupling groove 111, and the long-width portion 121a moves in the space 112 opened downward in the inside of the wall portion 110, It serves to support and fix the hem width portion 121b so that it is slidably fastened and prevents the body portion 120 from being separated after fastening. Here, the wall portion 110 and the body portion 120 maintain a solid L-shape in a coupled state.

In the drawings, it is illustrated that two coupling grooves 111 and two protrusions 121 are formed in the wall portion 110 and the body portion 120, respectively, but the number is not limited.
