Fig. 1 is structural representation of the present utility model.

Detailed description of the invention

Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clearly Chu, be fully described by, it is clear that described embodiment be only a part of embodiment of the present invention rather than Whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art are not making creation The every other embodiment obtained under property work premise, broadly falls into the scope of protection of the invention.

As it is shown in figure 1, this utility model includes burner hearth 1, feed arrangement, separator 2, superheater 3 and slagging Automatic dredging device, the upper and lower side of separator 1 upper and lower side with burner hearth 1 respectively connects, the upper end of superheater 3 with The upper end connection of separator 2, feed arrangement includes hopper 4, is arranged on the setting gauge of hopper 4 outfan, material toggling The outfan of device is connected with the charging aperture of burner hearth 1 by tremie pipe 16, setting gauge include circular tube shaped housing 5, The rotating shaft 6 being arranged in housing 5 and the switch-plate 7 being evenly distributed on radially in rotating shaft 6, rotating shaft 7 can be revolved Being inserted on the end cap at housing 5 two ends with turning, rotating shaft 7 is in transmission connection with driving motor 8, close on tremie pipe 16 The side of feed arrangement connects discharge pipe 17, and discharge pipe 17 connects cyclone dust extractor 18, cyclone dust extractor 18 are connected with air-introduced machine 19, and the top of tremie pipe 16 adds a discharge pipe, discharge pipe and air-introduced machine, draws Blower fan carries out convulsion to discharge pipe, and discharge pipe is contained within after the gas of micronic dust carries out dedusting dry by cyclone dust extractor Clean other are discharged by air-introduced machine so that pressure is removal from pipeline, reduce the malleation on material inlet top, The stable operation of the properly functioning and unit of guarantee equipment, is mainly possible to prevent during feed to beat malleation in boiler Ejection flame combustion equipment and cause feed bin firing accident.

The bottom of burner hearth 1 is provided with partition wall 27, and burner hearth 1 lower space is divided into dreg discharging area 9 and fluidization regions by partition wall 27 10, charging aperture is arranged on dreg discharging area 9, is provided with the inclination step cloth aerofoil being obliquely installed bottom dreg discharging area 9 11, tilt phase step type air distribution plate 11 extreme lower position and slag-drip opening 13 is set, tilt and arrange on phase step type air distribution plate 11 Wind cap 20, the air outlet of wind cap 20, towards slag-drip opening 13, is provided with air distribution plate bottom fluidization regions 10 14 and blast cap 15.The object being provided with the inclination step cloth aerofoil being obliquely installed, particle diameter and density bigger exists In dreg discharging area, under gravity and wind cap purging effect, move to slag-drip opening direction from the garbage inlet of burner hearth Dynamic, leave burner hearth through slag-drip opening, solve that fluidized bed refuse incinerator deslagging is smooth, need frequent blowing out to arrange Slag problem.Burner hearth is separated into dreg discharging area and fluidization regions by partition wall, suitably increases and enters dreg discharging area from wind cap Air quantity, i.e. increase the fluidising air velocity of dreg discharging area, advantageously ensure that deslagging is unobstructed, under the effect of partition wall, Particle diameter and the bigger material of density are blocked in dreg discharging area, thus, even if the fluidising air velocity of fluidization regions is relatively low It is also ensured that normally fluidize.

Slagging automatic dredging device includes high temperature resistant dredging bar 20, kinematic link 23, work connecting rod 22 and transmission Device 25, high temperature resistant dredging bar 20 is located at the lower section of slag-drip opening 13, wherein, high temperature resistant dredging bar 20 and work Connecting rod 22 is connected by universal joint 21, and high temperature resistant dredging bar 20 end is pyramidal structure, and kinematic link 23 is placed in On support 24, kinematic link 23 is connected through the hinge by two pole, and support 24 is connected with mentioned hinge, its In one pole with work connecting rod 22 be connected through the hinge, another pole pass through actuating device 25 control, separately One pole is connected with hand lever 26.When in burner hearth, operating condition foreign matters from being blocked slag-drip opening occurs extremely, open Dynamic actuating device, makes high temperature resistant dredging bar stretch into burner hearth to the blocking in slag-drip opening under the effect of kinematic link Thing is purged, afterwards root actuating device return, makes Mobile Communication on guiding valve cross the effect of connecting rod high temperature resistant dredging Bar exits burner hearth, and the most reciprocal action of this process constantly removes blocking foreign body, until slag screen is the most smooth Till Tong.Additionally can be switched to manual mode work when actuating device fault, manually bar controls to pass Dynamic connecting rod moves up and down, and does not affect the mass effect to slagging dredging work.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All within spirit of the present utility model and principle, any modification, equivalent substitution and improvement etc. made, all Within protection domain of the present utility model should be included in.
