Description

The cold slag machine in the many storehouses of membrane type double shell

Technical field

The utility model relates to the cold slag machine of drum-type, particularly adopts the cold slag machine of rotating cylinder of twin-roll, branch chamber structure.

Background technology

The cooling of solid granule and powder and the recovery of waste heat thereof are industry imperative equipment such as metallurgy, electric power, chemical industry, the energy, building materials.In the prior art, the cooling of solid particle and powder and the recycling of waste heat are limited, its main cause is that existing cold slag machine drum body is rolled by steel plate and forms, the cold slag machine of large-tonnage rigidity and bear the hydraulic pressure ability and diminish when barrel diameter is big, increase that barrel thickness is unfavorable for conducting heat and heat exchange area brief biography heat ability is low, heat transfer coefficient is little.The heat exchange difficulty, the waste heat recovery loss of unit material is many, has limited the cooling of solid particle and powder and the utilization of waste heat recovery.

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.

The specific embodiment

Fig. 1 illustrates, and the cold slag machine in the many storehouses of membrane type double shell is made up of feed arrangement 1, swing roller 2, drawing mechanism 7, supporting arrangement 3, power set 4, anti-play device 5, water system distributor 6.Rotary barrel 2 is made up of the inner core 2b and the urceolus 2a 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 6c and inner core feed end circulating line 6d respectively, the two ends of all cooling water pipes of urceolus are communicated with urceolus discharge end circulating line 6a and urceolus feed end circulating line 6b respectively, in, urceolus discharge end circulating line 6c, 6a is communicated with water inlet manifold, in, urceolus feed end circulating line 6d, 6b is communicated with the return pipe 6e that is provided with along rotary barrel 2 axis; Radially arrange, be divided into 4～7 cooling storehouse 2d 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 6e respectively; Be welded with the lifting blade 2e (referring to Fig. 6 Fig. 7) that is provided with by spiral form on the inwall in cooling storehouse.Exactly, the cooling storehouse inwall be by cooling water pipe and with it the welding band steel constitute, lifting blade is welded on the cooling water pipe.Better mode is: lifting blade 2e presses the setting of multi-head spiral form.
