Existing various cold slag machine can't be burnt the coke in the end slag, waste heat can not be transported boiler, or poor effect, can't overcome the wearing and tearing of metal heated of cold slag machine heat exchange, makes service life of equipment short, shuts down maintenance frequently.In addition, equipment volume is big, heavy in addition, cost is high, defectives such as operation power consumption height.

The applicant has patent " the cold mucking machine in oscillatory type geomantic omen " (Chinese patent ZL 200520097879.2), the warm sludge that the sulfuration bed is discharged enters vibrated bed by sliding dreg tube, twin shaft inertia vibration generator, the vibrated bed vibration of eccentric block are arranged in the driven by motor, and the vibrated bed end has slag notch.Vibrated bed is supported by the vibration gripper shoe, and the vibration gripper shoe is held by mounting etc., and vibration gripper shoe, mounting lower end are fixed on the base, and the base top is an air compartment, and air compartment links to each other with the boiler primary air fan.During work, vibrated bed vibration, lime-ash advances in vibrated bed, and the cold air of the lime-ash that advances through between the water-cooled of vibrated bed, water-cooling wall, vibrated bed, heat exchange carries out heat exchange, and the cooling back is discharged by the slag notch of vibrated bed end.

Summary of the invention

The purpose of this utility model is at above-mentioned present situation, aims to provide a kind of have defeated slag, cold slag, recovery waste heat function, does not block stifled, not easy to wear, in light weight, easy to maintenance, power saving, oscillatory type that cost the is low cold slag machine of economizing on coal.

The implementation of the utility model purpose is, the oscillatory type cold slag machine of economizing on coal, the vibrator that eccentric block is arranged in motor drives by V belt, vibrated bed has the vibration gripper shoe to support, the vibration gripper shoe is held by screw rod, screw rod is fixed on the mounting, mounting and vibration gripper shoe lower end are fixed on the base, the vibrated bed tail end has deslagging device, base, the heat exchanger base plate and between wallboard constitute an airtight air compartment, airtight air compartment have air inlet and communicate with heat exchanger do not leak the slag member, the heat exchanger tail end has the cold wind import, front end has hot-blast outlet, there is the warm sludge inlet pipe vibrated bed top, and the outlet of warm sludge inlet pipe has the slag input adjustment doors.

During the utility model work, the vibrator of eccentric block in driving by V belt, motor is arranged, the vibrated bed vibration.The boiler warm sludge is fallen on the vibrated bed through the slag input adjustment doors from the warm sludge inlet pipe, advances in vibrated bed, carries out heat exchange with two strands of cold wind in advancing, and the hot blast after the heat exchange is sent into boiler from hot-blast outlet, as the part of boiler secondary air.Warm sludge is fallen conveyer belt automatically from the deslagging device of vibrated bed tail end and is transported after heat exchange.

The utility model can smooth delivery of power and effective cooling warm sludge, and can burn the coke in the warm sludge, and hot blast is sent into boiler from hot-blast outlet, and as boiler secondary air one one can make saving coals from boiler.The utility model cooling effectiveness height, wearing and tearing be little, do not block stifled, in light weight, easy to maintenance, power saving, cost is low, effectively protected environment, saved the energy.
