The utility model content
The purpose of this utility model provides that a kind of heat transfer area is big, the cold slag machine in the many storehouses of the better membrane type double shell of cooling effect.
This novel purpose is achieved in that the cold slag machine in the many storehouses of a kind of membrane type double shell, mainly by rotary barrel, supporting arrangement, power set, feed arrangement and drawing mechanism are formed, rotary barrel is made up of the inner core and the urceolus that are provided with along same axis, inner core and urceolus constitute along circumferentially welding in turn through band steel by cooling water pipe, and the two ends of all cooling water pipes of inner core are communicated with inner core discharge end circulating line and inner core feed end circulating line respectively, the two ends of all cooling water pipes of urceolus are communicated with urceolus discharge end circulating line and urceolus feed end circulating line respectively, in, urceolus discharge end circulating line is communicated with water inlet manifold, in, urceolus feed end circulating line is communicated with the return pipe that is provided with along the rotary barrel axis; Radially arrange, be divided into 4~7 cooling storehouses between the cooling water pipe of band steel welding is with inside and outside tube, the two ends of cooling water pipe are communicated with water inlet manifold and return pipe respectively; Be welded with the lifting blade that is provided with by spiral form on the inwall in cooling storehouse.
The beneficial effects of the utility model are:
Cold slag machine horizontal positioned drags rotary drum rotating by power set, and swing roller is supported by supporting arrangement, and anti-play device prevents cylindrical shell front and back play.Swing roller is twin-roll, many chamber structures, arranges lifting blade by certain angle of inclination in 4~7 cooling storehouses, forms multi-head spiral.When hot materials flow enters swing roller inside from cold slag machine feed end, material is distributed each cooling storehouse by cutting plate, lifting blade promotes operation to discharge end from four to seven cooling storehouses respectively with material, in the material moving process, feed water in the swing roller pipeline as cooling medium, carry out countercurrent flow with material, material heat is reclaimed by cooling medium.Lifting blade is continuously constantly thrown material hot material forward and is scattered in roller rotating process; form the material curtain at the materials flow section; upgrade the materials flow heat-transfer area fast; improve the heat transfer rate of material intergranular and material intragranular portion; strengthen the solid material coefficient of heat transfer; so cooling solid particle or powder material fast import the heat of material into cooling water.The heat exchange area of the cold slag machine of this structure is big, is 3~4 times of plate-type slag-cooler, cooling heat transferring is effective, tapping temperature is low; It is big to bear pressure.
This is novel to be applicable to the cooling of hot solid granule and powder and recovery, utilization and the environmental protection of waste heat thereof, is particularly suitable for the slag cooling of the above big volume flow fluidized bed boiler of 30MKW.Can be widely used in metallurgy, electric power, chemical industry, the energy, building material industry mechanical equipment technical field.
