Cylinder apparatus is connected and is moved reciprocatingly under the promotion of cylinder apparatus, and the lower section of the push plate is equipped with burning inlet air plenum, described
The ash discharging gear for recycling fuel ash is additionally provided with below rack.
Further, the push plate is " rake " shape, and the water cooling plant is located in the concave surface of the push plate.
Further, the water cooling plant is water pipe and the band steel being connect with water pipe, and the band steel is equipped with several ventilations
Hole, the water pipe water inlet are connect with outer tank, and the water pipe water outlet is connect with boiler.It is cold when push plate works normally
Water extends fire grate service life into cooling push plate in outlet pipe, is played the role of；Water after heating enters boiler, and heat is whole
It utilizes, improves the thermal efficiency of boiler.
Further, the burning inlet air plenum is equipped with the regulating device that can adjust air intake, to control entrance
The air quantity of ventilation hole achievees the purpose that fuel completely burned.
Further, the fuel-feed bucket is equipped with high-low-position level-sensing device, can be realized according to the height of material position automatic
Charging reduces manual labor.
Further, the top of the push plate is equipped with burner hearth, and fuel combustion is more advantageous to during burning.
Above-mentioned technical proposal is used, the utility model has advantageous effect below：
1, the utility model fire grate horizontal reciprocating moves, and allows particle ceaselessly to roll on grate surface and burns, Zhi Daochong
Divide after-flame, efficiency of combustion is improved to 95% or more；
2, the utility model uses water-cooled structure, does not use traditional alloy fire grate segment, from investment cost cost, greatly
It is less than traditional fire grate, the more market competitiveness greatly.
