Background technology
Biomass boiler is that our times various countries generally generally acknowledge the energy-saving, environmental protection boiler using, the fuel of boiler is mainly with the stalk in crops, house refuse, mud etc., compressing forming after pulverizing, the general capacity of boiler less (50MW is following), the use of the generating of the small hydropower station in applicable city and central heating, not only environmental protection but also energy-conservation.The hot lime-ash processing of environment friendly biological matter boiler, it is one of critical process of steam power plant, because of biomass boiler small volume, the space of slagging tap below boiler is just less, by fill not Shang barrel slag cooler and other slag-tapping device, if the lime-ash water of boiler discharge washes away, waste water and polluted again environment, if artificial treatment warm sludge, had not both met safety requirements, warm sludge can damage again conveying equipment.Therefore, the hot ash handling of biomass boiler must be short again little, can carry again by cold slag.
The cylinder type cold slag machine that generation current factory is used, mainly supporting to large-scale (more than 50MW) fluidized-bed combustion boiler, cylinder type cold slag machine volume is large, process cooling lime-ash ability large, its structure is the effect that rotation outer cylinder body reaches cooling lime-ash, its weak point is that boiler bottom must have sizable space, could move its equipment.
Summary of the invention
The utility model object be to provide a kind of volume short and small, use flexiblely, equipment installation period is short, the cold slag machine of reliable stable helical feed.
The technological means that the utility model adopts is:
The cold slag machine of a kind of helical feed, comprise helix transporting device, the boiler cinder notch that falls, bracing frame, described helix transporting device comprises main shaft, spiral conveying blade, shell, driving mechanism, described main shaft is hollow shaft, described main shaft is provided with spiral conveying blade, described main shaft one end is connected with swivel joint by bearing block A, described swivel joint connects two water pipes, the described main shaft other end is connected and fixed by bearing block B and driving mechanism, described spiral conveying blade is provided with shell outward, described shell front end is provided with cooling water inlet, described outer casing back is provided with coolant outlet, described coolant outlet place is provided with electro connecting pressure gauge, safety valve, described outer casing back below is provided with the pipeline of slagging tap, described shell front end top is provided with slag dropping tube road, described slag dropping tube road and the boiler cinder notch that falls is tightly connected, described slag dropping tube road is provided with high temperature cut-off valve, the leading portion of described helix transporting device, stage casing, back segment is respectively equipped with bracing frame.
The cross section of described helix transporting device is semicircle.
Described shell is interlayer.
Circulating cooling medium in described hollow shaft, interlayer is: cooling water.
Beneficial effect: the utility model is owing to having adopted above structure, equipment volume is short and small, it is flexible to use, equipment installation period is short, reliable stable, and can connect computer controlled automatic by temperature control equipment, can in ash-slag delivery, carry out cooling lime-ash, take up room little.
