It is made of a material that can prevent wear due to friction with the moving grate as much as possible, and a support frame made of heat-resistant steel that supports the lower part of the castable block and roast block is a reinforcing frame coupled to the front of the channel bracket. Since it is bolted to the front of the channel bracket using a bolt, the castable block and the lost block can be double supported, which not only increases the coupling force but also facilitates replacement of the support frame or lost block, It relates to a drop-off structure for an incinerator that allows the spacing of the roast body coupled to the front of the castable block to be maintained by spacing maintainers formed at equal intervals on the inside of the reinforcing frame.

In general, an incinerator is a device that incinerates and disposes of waste generated from living or industrial sites.

Figure 1 shows an incineration chamber 10.

Inside the incineration chamber 10, a moving table 10 and a fixed table 40 are installed in the longitudinal direction to form multiple stages.

A plurality of movable grates 30 are installed on the movable table 10, and a fixed grate 50 is installed on the fixed table 40 to be located below the movable grates 30.

Therefore, the waste flowing into the incineration chamber 10 is gradually moved to the lower part of the incineration chamber 10 by the moving grate 30 that moves forward and backward along the upper surface of the fixed grate 50. It is then incinerated.

According to the incineration process of the waste incinerated inside the incinerator 10, it is roughly divided into a drying area (D), a combustion area (C), and a post-combustion area (AC), and the drying area (D) and the combustion area (C) ), and between the combustion area (C) and the post-combustion area (AC), a drop stage (SP) is formed to shake off the waste.

As described above, a drop edge (SP) is formed at the rear end of the drying area (D) and the rear end of the combustion area (C), respectively, and movement from the drying area (D) to the combustion area (C) is performed by the drop end (SP). In the process, the waste is first mixed and mixed, and in the process of moving from the combustion area (C) to the post-combustion area (AC), it is mixed secondarily to ensure complete combustion.

Figure 2 shows a drop structure for a conventional incinerator.

A channel bracket 200 with an installation groove 201 is formed on the fixture 40 provided at the drop end (SP), and a castable block 210 made of refractory material is coupled to the installation groove 201. By installing, a drop break (SP) is formed.

Therefore, the castable block 210 provided at the drop stage (SP) supports the lower part of the fixed grate 50.

And a scraper 220 is installed to rotate up and down at the lower front end of the castable block 200.

The front end of the scraper 220 is axially installed at the bottom of the castable block 210 in close contact with the upper surface of the movable grate 30 provided at the drop end SP by its own weight.

Therefore, as the castable block 210 made of refractory material is installed at the drop end (SP) using the channel bracket 200, the high temperature heat generated when the waste is burned is blown into the mechanical installation inside the incineration chamber 10. It is possible to prevent it from entering the place (inner space of the grate), and the scraper 220 provided at the front lower part of the castable block 210 allows the combustion area (C) and post-combustion area to be removed through the drop stage (SP). This can prevent waste that has fallen into the (AC) from flowing into the inside of the incinerator.

However, the problem with the conventional fall stage structure for incinerators is that the castable block 210 made of a refractory material is fixedly coupled to the channel bracket 200 provided at the stage block (SP), and the castable block 210 ), by installing a scraper 220 in close contact with the upper surface of the mobile grate 30 at the lower part of the front end,

In the process of moving the moving grate 30 forward and backward, friction with the scraper 220 causes deterioration, damage, and corrosion, which causes problems such as uneven operating temperature and partial overheating of the incinerator.

Therefore, in order to replace the worn scraper 220 or the movable grate 30, the castable block 210 must be broken and then replaced using a separate tool, so the scraper 220 and the movable grate 30 ), a problem arose in which it was not easy to replace.

In addition, cracks occurred in the castable block 210, making it difficult to replace.
