Turnover fire grate segment for incineration

Abstract

The utility model provides a turning fire grate segment for incineration, which relates to the technical field of garbage disposal and comprises a turning fire grate segment, a main body of the turning fire grate segment is of a composite sheet structure and is composed of a flat plate on the side face and a protruding outer edge structure, and a clamping die structure for assembly is arranged on the inner side of the turning fire grate segment. A hinge hole for positioning and mounting is formed in the turning fire grate sheet; combustion-supporting air holes are formed in the inner corners of the outer edges of the turning fire grate segments in a manner of penetrating through the turning fire grate segments; by improving the shape of the outer angle of the outer edge of the turning grate segment, the situation that iron blocks, nuts and harder stones in garbage are clamped between the hood and the fixed grate segment in the turning and falling movement process of the turning grate, and consequently the turning grate segment cannot return in place can be avoided, and therefore the whole operation of the incineration grate is more stable, and the failure rate is reduced.

Description

Technical Field

[0001] This utility model belongs to the field of waste treatment technology, and more specifically, it relates to a turning grate for incineration. Background Technology

[0002] The operation of the incinerator grate mainly involves the uniform, continuous, and controllable combustion of the input waste, ensuring that the combustible components in the waste are fully burned, while reducing the emission of unburned materials.

[0003] The grate, driven by mechanical transmission, continuously propels the waste from the inlet to the outlet. During this process, the waste is affected by the temperature, oxygen concentration, and other conditions in different areas of the grate, resulting in varying combustion conditions. To better achieve the stages of drying, pyrolysis, combustion, and burnout, our company has designed grate plates with sliding grate plates, tilting grate plates, and fixed grate plates.

[0004] Based on the above, the original design of the rotating grate had an outer edge protruding from the arc at the front end of the grate, with the air vent below the outer edge. During the rotation of the grate, iron blocks, nuts, and hard stones in the waste would get stuck between the air vent and the fixed grate, causing the rotating grate to not retract properly. Since the sliding grate and the rotating grate were interlocked in their operation, the rotating grate could not retract properly, and the sliding grate could not move forward, affecting the overall operation of the incinerator. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tilting grate for incineration, which solves the problem mentioned in the background art that during the tilting grate's tilting and falling movement, iron blocks, nuts, and hard stones in the waste will get stuck between the air cap and the fixed grate plate, causing the tilting grate plate to not retract properly. Since the sliding grate and the tilting grate's action program are interlocked, the tilting grate cannot retract properly and the sliding grate cannot move forward.

[0006] The purpose and effect of this utility model for a rotating grate for incineration are achieved by the following specific technical means:

[0007] A rotating grate for incineration includes a rotating grate plate. The main body of the rotating grate plate has a composite sheet structure, consisting of a flat side plate and a protruding outer edge structure. An assembly clamping structure is provided on the inner side of the rotating grate plate. A hinge hole for positioning and installation is provided in the rotating grate plate. A combustion air hole is provided through the inner corner of the outer edge of the rotating grate plate.

[0008] Furthermore, the outer corners of the rotating grate are rounded.

[0009] Compared with the prior art, the present invention has the following beneficial effects:

[0010] By improving the shape of the outer corner of the flipping grate, it is possible to avoid iron blocks, nuts, and hard stones in the waste getting stuck between the air cap and the fixed grate during the flipping grate's rising and falling motion, which would prevent the flipping grate from retracting properly. This makes the overall operation of the incinerator grate more stable and reduces the failure rate. Attached Figure Description

[0017] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0018] Example 1:

[0019] As attached Figure 1 To be continued Figure 2 As shown:

[0020] This utility model provides a tilting grate for incineration, including a tilting grate 1. The main body of the tilting grate 1 is a composite sheet structure, consisting of a flat side plate and a protruding outer edge structure. An assembly clamping structure is provided on the inner side of the tilting grate 1. A hinge hole 101 for positioning and installation is provided in the tilting grate 1. A combustion air hole 102 is provided through the inner corner of the outer edge of the tilting grate 1. The shape of the combustion air hole 102 can be adjusted as needed, but the position remains unchanged.

[0021] Among them, the outer corners of the outer edge of the turning grate plate 1 are rounded.

[0022] The specific usage and function of this embodiment are as follows:

[0023] In this invention, by improving the shape of the outer corner of the outer edge of the flipping grate plate 1, it is possible to avoid the situation where iron blocks, nuts, and hard stones in the garbage get stuck between the air cap and the fixed grate plate during the flipping grate's rising and falling motion, causing the flipping grate plate 1 to fail to retract into place. This makes the overall operation of the incinerator grate more stable and reduces the failure rate.
