Summary of the invention
The purpose of this utility model is for the above-mentioned problems in the prior art, and a kind of slag-bonding protective device that can prevent the biomass boiler of slagging scorification is provided.
The purpose of this utility model can realize by following technical proposal: a kind of slag-bonding protective device of biomass boiler, it is located at the side that combustion chamber has charging aperture, it is characterized in that, this slag-bonding protective device comprises that one is positioned at charging aperture below and horizontally disposed push rod, the inner of described push rod is longitudinally stretched in combustion chamber and this inner pushing block that is strip that is fixed with horizontally set, bottom surface setting and pushing block that described pushing block is close to combustion chamber have the vertical top of the slag that pushes away, and the outer end of described push rod is fixed with the actuator that drives push rod axially reciprocating.
Biomass fuel enters burning Indoor Combustion from charging aperture, the polybag containing in biomass fuel, after tire debris burning, form the residue of jelly, in the slag-bonding protective device of this biomass boiler, actuator drives push rod shaft to burning indoor moving, pushing block has the vertical top of the slag promotion residue that pushes away and moves to middle part, combustion chamber, avoid residue to be attached to and be positioned on the bottom surface, combustion chamber of charging aperture below, prevent slagging scorification, in said process, pushing block also promotes biomass fuel to middle part, combustion chamber, improved efficiency of combustion, actuator drives push rod shaft to moving away from middle part, combustion chamber direction afterwards, pushing block is reset to that to push away slag next time ready.
The combustion chamber of existing biomass boiler all has slag notch, and slag notch is positioned at the place, bottom of the sidewall of combustion chamber on charging aperture opposite, and pushing block reciprocating in the slag-bonding protective device of this biomass boiler, can be pushed into residue slag notch place, convenient processing.
In the slag-bonding protective device of above-mentioned a kind of biomass boiler, described push rod be positioned at charging aperture under, described pushing block is positioned at the inner top of push rod and the centre position, bottom surface of pushing block is connected mutually with push rod, and the length of described pushing block is greater than the bore of charging aperture.Be arranged so that like this pushing block pushes away slag complete.
In the slag-bonding protective device of above-mentioned a kind of biomass boiler, the rectangular triangle in the cross section of described pushing block, the bottom surface of described pushing block is horizontal plane.When push rod drives pushing block axially when moving away from middle part, combustion chamber direction, the inclined-plane climbing that biomass fuel can have along pushing block, biomass fuel can fall within pushing away before the top of the slag of pushing block, avoid like this biomass fuel to remain between pushing block and sidewall of combustion chamber, pushing block can be released biomass fuel again when move at middle part, combustion chamber, makes biomass fuel utilization rate high.
In the slag-bonding protective device of above-mentioned a kind of biomass boiler, on described combustion chamber, be fixed with fairlead, described push rod is through fairlead setting.Fairlead plays guide effect, makes the good stability of push rod axially reciprocating.
In the slag-bonding protective device of above-mentioned a kind of biomass boiler, described actuator is cylinder or pushing motor.
Compared with prior art, the slag-bonding protective device of this biomass boiler can prevent slagging scorification, and pushing block can also promote biomass fuel to middle part, combustion chamber, make biomass fuel combustion abundant, has improved efficiency of combustion.
