Description
Technical field
The present invention relates to technical field of waste incineration, particularly relate to the stokehold feeding system of a kind of incinerator.
Background technology
The feeding manner of current domestic incinerator adopts bipacking-auger screw feeder, piston-type to add shaftless screw feeding machine to material to material and single roller material toggling formula to material, hydraulic efficiency piston pushing device to material, chain-plate type mostly.
Adopting bipacking-auger screw feeder, shortcoming is that two roller is easily wound around by rubbish, causes charging bite block, and process, maintenance difficulties greatly, make operation discontinuous. Adopt piston-type to material, shortcoming be piston when being subject to resistance, due to the easy step-out of distribution of system pressure, make to material uneven, cause furnace pressure fluctuation big, accordingly that the damage of furnace body is also big. Adopt chain-plate type to material, shortcoming is that inleakage is bigger, the stopping property of equipment is poor, it is difficult that the sealed structure of the sound junction being connected with furnace body arranges comparison, the economy run being had a certain impact, be secondly the poor working environment due to chain mat machine, erosion corrosion is comparatively serious, maintenance workload is bigger, and its maintenance cost accounts for larger proportion in overall maintenance cost. Adopt single roller material toggling formula feed-type, shortcoming is that this equipment can not realize stokehold and deposits material, subsidiary engine with matching must be had continuously to supplement rubbish in feeding machine, due to the unreasonable structure of itself and tremie pipe, the probability of feeding machine blocking is higher, also having flue gas to emerge during rubbish detonation malleation, the speed reduction unit of equipment and motor are had certain influence by high-temperature flue gas. A kind of hydraulic efficiency piston pushing device emerging at present adds the feeding system of shaftless screw feeding machine combination, shortcoming is material-pulling device failure rate height, and pusher process easily causes top hopper material bridging blocking, and adopt simple helix feeding machine, also material bridging is more easily formed in feeding machine, under identical feeding coal, simple helix feeding machine overall dimensions is relatively big, and cost and energy consumption are higher.

Preferably, in above-mentioned stokehold feeding system, between the outlet of described shaftless double-spiral feeder and the opening for feed of incinerator, it is provided with tremie pipe; Described tremie pipe is also provided with air-cooled chuck.
Compared with prior art, the hopper of the present invention, owing to its profile is at right angles trapezoidal, therefore is more conducive to blanking in structure.
In addition, the present invention also has following advantage:
The first, hopper arranges brokenly Biodge device, it is possible to prevent hopper feed opening material bridging from blocking. Level gage installed by hopper, in order to control the enough bed depths of hopper, ensures the favorable sealing property of whole feeding system, prevents system air leakage and boiler smoke anti-channeling.
Two, material pushing box adopts casing pattern, it does not have material wrapping phenomena, device failure rate is low, and in pusher process, material is carried out more effective attrition crushing.
Three, shaftless double-spiral feeder is adopted, eliminate the bearings of tunnel shaft and afterbody, it it is the pattern of a kind of cantilever strand dragon, achieve non-axis transmission, solve the problem that garbage feeding is wound around on axle, without axle construction and duplex charging side by side, making not easily to put up a bridge in feeding machine blocking, discharge gate also not easily blocks, because its discharge capacity is big, therefore under identical feeding coal, this device size is little, and cost is low, and can relatively lower velocity operate, steady transmission, reduces energy consumption, and shaftless double-spiral feeder can also realize continuous uniform to material;
Four, feeding machine tremie pipe is provided with air-cooled chuck, reduces feeding machine heating temperature, reduces equipment failure rate.
