Description

Technical Field

[0001] The utility model belongs to the technical field of garbage incineration equipment, in particular to a grate block and a garbage incinerator. Background Art

[0002] With the progress of urbanization, the amount of garbage disposal continues to rise, and the requirements for garbage disposal are also getting higher and higher. At present, the garbage disposal method commonly adopted by countries around the world is garbage incineration. This method can not only effectively save land resources, but also improve garbage reduction and resource utilization. Among them, mechanical grate furnace is the most widely used garbage incineration technology.

[0003] Mechanical grate furnaces are generally composed of several grate sections, usually divided into drying, combustion, and burnout sections, with each section having an inclination. Garbage needs to be dried, burned, and burned out on each grate section, and discharged into the slag well after full combustion. Because the garbage is burned directly on the surface of the mechanical grate, the temperature it withstands is extremely high. Although a layer of "ash pad" separates the grate block and the combustion layer to block some heat, the surface temperature of the grate block can still reach over 600°C to 700°C. To ensure the safe and reliable operation of the grate block, effective air cooling must be adopted. In addition, when the mechanical grate furnace is operating, the fuel in the grate block moves evenly and burns on the grate block. Air passes through the grate block and the fuel layer from bottom to top through the wind chamber under the grate block, providing sufficient oxygen for the fuel.

[0004] In order to ensure the ventilation rate of the grate block, ventilation holes or vents are usually set on the surface of the grate block cover plate. However, the ventilation holes or vents are located on the surface of the grate block cover plate, which is easy to be blocked and the ventilation effect is poor. In addition, due to the connection structure between the grate block cover plate and the grate block bracket, there is a gap between the surface of the grate block cover plate and the grate block bracket, resulting in a high slag leakage rate and a high slag thermal loss rate.

[0005] Therefore, how to effectively improve the ventilation and cooling effects of the grate blocks, reduce the slag leakage rate and the thermal burn-off rate is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0036] In view of this, the core of the present invention is to provide a grate block that can effectively improve the ventilation and cooling effects of the grate block, reduce the slag leakage rate and the thermal burn-off rate.

[0037] Another core of the utility model is to provide a garbage incinerator.

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

The support assembly 300 can lift the grate cover 100 so that a ventilation gap for ventilation is formed between the side edges of the grate cover 100 and the grate base 200.

[0040] Compared with the prior art, since the ventilation gaps disclosed in the embodiment of the utility model are arranged on the side of the grate block and are not in direct contact with the garbage, the grate block is not easily blocked, which not only effectively improves the ventilation and cooling effects, but also greatly reduces the slag leakage rate and thermal burn-off rate.

[0041] In addition, the grate block disclosed in the embodiment of the present invention has a separate structure of the grate cover 100 and the grate base 200, and the grate cover 100 is a wearing part. Therefore, after the grate cover 100 is worn, only the grate cover 100 needs to be replaced, and there is no need to replace the entire grate, which greatly reduces the operating cost.

[0042] It needs to be explained that the mechanical grate is the hearth for burning domestic waste, which transports, stirs and turns the waste inside the furnace; the grate block refers to the parts installed on the surface of the grate and are in direct contact with the waste; the slag leakage rate refers to the percentage of slag falling from the gaps in the grate blocks to the total slag volume; the thermal loss rate refers to the percentage of the mass of the incineration residue reduced by heating to the mass of the original incineration residue.

[0043] As a further embodiment, the sidewall of the grate base 200 disclosed in the embodiment of the present invention is further provided with ventilation holes. Such a configuration can further improve the ventilation and cooling effect of the grate block, thereby further reducing the slag leakage rate and thermal burn-off rate.

[0044] Of course, the grate cover 100 and the grate base 200 disclosed in the embodiment of the present invention can also be set to seamless welding, and only ventilation holes are set on the side wall of the grate base 200, which can also achieve the purpose of improving the ventilation and cooling effect of the grate block, thereby reducing the slag leakage rate and thermal burn-off rate.
