Description

The burner of biomass fuel combustion stove

Technical field

The utility model relates to the boiler of firing biomass fuel, specifically is the burner in the stove.

Background technology

Biomass fuel specifically has the straw granular fuel, is that national policy is helped the environmental protection project of promoting in recent years.Crop straw, dead leaf in will discarding autumn afield loses dry plant refuse such as branch, rice husk, corn ear to be pulverized, and through the mechanical presses moulding, becomes granular fuel.This fuel does not produce harmful burnt gas, not air pollution, and ashes also contain materials such as phosphorus, potassium, can make the fertilizer auxiliary material.Yet existing market is sold effective often first-class, meticulous, impure few to the demanded fuel price of biomass fuel combustion stove, and the ash amount that low-cost fuel produces is big, because of containing also easily coking such as sand, maize pulp saccharic more, burn insufficient, calorific value is low, this has just influenced promoting the use of of this fuel.Stove and accessory also has deficiency: burner only is equivalent to the container of fuel in most of stoves, and the chassis is porose, only for ventilating from bottom to top, lime-ash is taken away with the wind, and the slag that coking becomes then will manually be removed, and draw slag once per half an hour, need the artificial burning that monitors, so use the cost of this fuel also to rise.

Summary of the invention

The purpose of this utility model provides a kind of burner of biomass fuel combustion stove, and disintegrating slag, scarfing cinder automatically is not fastidious to fuel mass, obvious energy conservation.

The burner of biomass fuel combustion stove, comprise casing, Lu Quan, stone or metal plate for standing a stove on as a precaution against fire, establish electric igniter at combustion furnace circle inwall, it is characterized in that stator stove circle inwall has shift fork, shift fork and inwall be inclined at acute angles and with rotor stone or metal plate for standing a stove on as a precaution against fire direction of rotation, the chucking lug of stator stove circle is fixed on the upper surface of burner outer case, and stator stove circle embedded in the casing by upper surface, in stator Lu Quan lower end one embedded slideway is arranged, the rotor stone or metal plate for standing a stove on as a precaution against fire is inlaid into slideway by stator Lu Quan lower end, and rotor stone or metal plate for standing a stove on as a precaution against fire edge and stator Lu Quan lower end inwall slideway formation are slidingly matched; At rotor stone or metal plate for standing a stove on as a precaution against fire center one rectangle open-work is arranged, the cuboid prism of vertical shaft upper end is inserted in the rotor stone or metal plate for standing a stove on as a precaution against fire central bore, there is bevel gear the vertical shaft lower end, with two gears engaged on the power transmission shaft, one of two bevel gears cooperate with the transmission axle key on the power transmission shaft, and become travelling gear by the location of the screw on screw rod and the power transmission shaft, and symmetrically arranged another gear is a floating gear, by the axle sleeve location, power transmission shaft is by driven by motor.

The design maintains static burner stator stove circle wall, in the stator stove circle fixedly shift fork is arranged, and height distance is arranged with rotor stone or metal plate for standing a stove on as a precaution against fire upper surface, when the rotor stone or metal plate for standing a stove on as a precaution against fire to shift fork incline direction backwards rotation the time, coking after shift fork will burn naturally is along the cleaning door deslagging on stator stove circle and the casing.The design saves manpower, and the biomass fuel quality there is not requirement, even biomass fuel is impure more, also can not stop up burner hearth because of coking.Contrast test: the biomass fuel with constant power calorific value, use equal quality is provided, the biomass boiler of the coal-fired boiler reform 180 kilograms of fuel that per hour burn, and the boiler that adopts the design's the burner 100 kilograms of fuel that per hour burn, save 80 kilograms of fuel/hour.

The specific embodiment

The burner of biomass fuel combustion stove, comprise casing, the stove circle, stone or metal plate for standing a stove on as a precaution against fire, establish electric igniter at burning stone or metal plate for standing a stove on as a precaution against fire inwall, this structure of accompanying drawings, it is characterized in that stator stove circle 5 inwalls have shift fork 10, see Fig. 1, Fig. 5, shift fork 10 is inclined at acute angles with stator stove circle 5 inwalls, and with rotor stone or metal plate for standing a stove on as a precaution against fire 4 direction of rotation, the chucking lug 9 of stator stove circle 5 is fixed on the upper surface of burner outer case 17, and stator stove circle 5 embedded in the outer case 17 by upper surface, at stator stove circle 5 lower end inwalls one embedded slideway is arranged, rotor stone or metal plate for standing a stove on as a precaution against fire 4 is inlaid into slideway by stator stove circle 5 lower ends, and rotor stone or metal plate for standing a stove on as a precaution against fire 4 edges and stator stove circle 5 lower end inwall slideways formations are slidingly matched; At rotor stone or metal plate for standing a stove on as a precaution against fire 4 centers one rectangle open-work is arranged, the cuboid prism of vertical shaft 7 upper ends is inserted in the rotor stone or metal plate for standing a stove on as a precaution against fire central bore, there is bevel gear vertical shaft 7 lower ends, with two gears, 8 engagements on the power transmission shaft 1, one of two bevel gears cooperate with power transmission shaft 1 key on the power transmission shaft, and become travelling gear by the location of the screw on screw rod and the power transmission shaft 1, and symmetrically arranged another gear is a floating gear, by the axle sleeve location, power transmission shaft 1 is by driven by motor.
