Problems solved by technology

There are various defects in the structure of the traditional reciprocating grate. First, the working conditions of the reciprocating grate are poor, and there is relative movement between the grates. Due to the influence of the high-temperature fuel layer, the grate pieces are prone to jamming and deformation. The mutual wear between the fixed grate and the movable grate makes the service life of the grate short and needs to be replaced frequently, which increases the maintenance cost and time of the boiler and reduces the running time of the boiler. In order to prolong the service life, the user has to replace the boiler The grate is made very thick to prolong the wear time and reduce the shutdown time of the boiler; second, the installation accuracy of the grate is low, and the gap between the grate is uneven, resulting in coal leakage and blockage of the ventilation hole, resulting in poor ventilation and resulting in fuel The combustion is uneven, and in some places the combustion is not sufficient, and the combustion efficiency decreases

Abstract

The invention discloses an anti-wear reciprocating fire grate supporting structure. The movable grate piece and the fixed grate piece are clamped on the movable shelf and the fixed shelf respectively, and the movable shelf and the fixed shelf are connected with a positioning plate set corresponding to the fire grate piece, and the two positioning plate sets of the positioning plate set The distance between them is slightly greater than the thickness of the grate ribs; the ribs of the grate can be inserted between the two positioning plates, which can prevent the movable or fixed grate from moving left and right, so as to keep the gap between the grate even and not As for the phenomenon of poor ventilation caused by coal leakage and blockage of ventilation holes, the combustion of fuel is more uniform and sufficient, thereby improving combustion efficiency. The movable grate and the fixed grate are respectively supported by separate support rods to prevent wear and friction between the movable grate and the fixed grate, improve the service life of the reciprocating grate, reduce the number of shutdowns of the boiler, and reduce the boiler The maintenance cost is reduced, and the efficiency of the boiler is improved.

Description

technical field [0001] The invention relates to a boiler fire grate, in particular to a boiler reciprocating fire grate device. Background technique [0002] The grate is a component that stacks solid fuel in a boiler or an industrial furnace and makes it burn effectively. The fixed grate piece and the movable grate piece are stacked at intervals to form a stepped grate surface, and the fuel moves on the grate surface. Its function is to gradually transport the fuel blocks falling from the silo to the slag discharge port, and make them fully burn during the transport process. There are various defects in the structure of the traditional reciprocating grate. First, the working conditions of the reciprocating grate are poor, and there is relative movement between the grates. Due to the influence of the high-temperature fuel layer, the grate pieces are prone to jamming and deformation. The mutual wear between the fixed grate and the movable grate makes the service life of the ...
