Description

Technical Field

[0001] The utility model relates to the technical field of grates, and more particularly to a flanging grate with an anti-jamming structure. Background Art

[0002] A grate, also known as a fire grate or combustion grate, is a key component in boilers, furnaces, and some cooking appliances. Its primary function is to support the fuel during combustion and promote uniform mixing of air and fuel, thereby improving combustion efficiency. The design and performance of the grate significantly impact combustion performance, energy efficiency, and emissions control.

[0003] After searching, the existing application number is: CN202410806828.X, which discloses a grate piece for reciprocating grate and a reciprocating grate. The grate piece is provided with a sliding groove and / or a longitudinal boss on the up-slope section and / or the down-slope section. Through the setting of the sliding groove and / or the longitudinal boss, the reciprocating grate can provide the coal seam with multi-wave longitudinal and transverse bidirectional staggered layer disturbance and staggered layer ignition function. At the same time, when the down-slope section of the grate moving piece is pushed forward, it can be aligned with the fixed piece on the front row. The coal seams carried between the inclined sections are subjected to positive counter-extrusion. When retreating, the upward inclined section of the moving grate can also perform reverse counter-extrusion on the coal seams carried between the downward inclined sections of the rear fixed sections. Therefore, it has strong coke and slag breaking functions, which is conducive to crushing the ash shell on the surface of the coal core and promoting oxygen penetration. It helps to accelerate the downward ignition speed of the flame in the coal seam, increase the effective combustion time of the bottom coal seam in the furnace, accelerate the burnout speed of the fire carbon and coal core, reduce the carbon content of the slag, and improve the thermal efficiency of the coal seam operation.

DETAILED DESCRIPTION

[0023] 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 the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Wherein: when the fuel is transported to the feeding area 2, the fuel is transported into the first conveying area 3 through the feeding area 2. At this time, the fuel is slowly transported into the incineration area 4 in a step-by-step manner in the first conveying area 3. At this time, the fuel is separated in the incineration area 4, and the first conveying area 3 is continuously transported to the incineration area 4 for new fuel, and the fuel in the incineration area 4 is pushed to continuously move to the second conveying area 5. At this time, when the fuel moved to the second conveying area 5 completely passes through the incineration area 4, and its fuel is completed in the incineration area 4 to release its energy, and then the waste fuel pushed out from the incineration area 4 falls inside the second conveying area 5. At this time, the nature of the waste fuel itself changes, and then when the waste fuel is pushed, the waste fuel is prone to breakage. At this time, the blocking assembly 7 provided between the first conveying area 3 and the second conveying area 5 is pushed out by the blocking assembly 7 for small fuel and the waste fuel broken into powder, thereby reducing its impurities from entering the interior of its incineration frame 1.
