Abstract
The utility model relates to a blade type heat-transfer rolling drum for cooling loose materials. The utility model is provided with a double-layer sleeve drum, wherein, the centre of the sleeve drum is provided with a core tube which is fixed with the inner wall of the sleeve drum and is communicated with the sleeve drum through a guide tube; longitudinal heat conduction blades are welded on the inner wall of the sleeve drum; longitudinal heat-transfer blades are welded on the outer wall of the core tube. The utility model has the advantages of homogeneous heat transfer, low energy consumption, light mechanical corrosion, and long service life.
Description
The utility model relates to a kind of heat transfer cylinder of cooling bulk material heat-transfer equipment, especially cylinder type cold slag machine.
Be used for the warm sludge cooling of fluid bed and fluidized bed boiler at present, adopt the cold slag machine of helix drum formula more, promptly in cylinder, inject cold water, drop into warm sludge, promote warm sludge by helical blade and carry forward and cool off.Its shortcoming is that material can not evenly stir, and cooling effect is poor, and demand motive force is big, and energy consumption height, part rapid wear need often to change, and influence ordinary production.
The purpose of this utility model is cylinder type cold slag machine is improved, and proposes a kind of new-type cylinder design scheme, so that the material cooling evenly, alleviates mechanical wear and cuts down the consumption of energy.
Structure of the present utility model is: have double layer sleeve barrel, the core pipe is equipped with in sleeve central authorities, and the core pipe is fixed with sleeve lining and communicated with sleeve by conduit, and sleeve lining is welded with vertical conduction vanes, and core tube wall is welded with vertical heat transferring vane.
Vertical conduction vanes and sleeve on the sleeve lining radially have an angle, can make partial material slowly can rest on vertical conduction vanes for a long time in the rotation with sleeve, thereby increased the area that material contacts vertical conduction vanes and barrel, also this part material is poured on the blade of core pipe the blade on the increase core pipe and the contact area of tube wall and material simultaneously.
Cooling water enters from the water inlet pipe of sleeve, discharges from the outlet pipe of core pipe, and the outlet pipe of the water inlet pipe of sleeve and core pipe is in same end, is convenient at the other end feed arrangement is set.
Sleeve lining is welded with the hoop blade of layout interlaced with each other, and there is an inclination angle in the cross section of hoop blade and sleeve, make material with the slow rotation central axis of sleeve to conveying, and can change the axial transporting velocity of material by the size that changes this inclination angle.
The utility model is compared with the cylinder of existing cylinder type cold slag machine has advantage: 1, the use of blade and core pipe, and make heating surface area big, conduct heat evenly the cooling effectiveness height.2, the rotating band animal material by cylinder advances, and demand motive force reduces, and has reduced energy consumption.3, mechanical wear alleviates, and has improved equipment life.
Description of drawings:
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the A-A cutaway view of Fig. 1.
Below in conjunction with embodiment and accompanying drawing thereof the utility model is described in further detail.
As depicted in figs. 1 and 2, the cylinder outside is a pair of lamina sleeve 2, and its right-hand member is a charging aperture, and left end is a discharging opening.The central authorities of sleeve 2 are core pipes 1, and the one end communicates by three uniform conduits 6 with sleeve 2 inwalls and welds fixingly, and 7 welding of the water inlet pipe of the other end and sleeve 2 are fixing, and water inlet pipe 7 communicates with sleeve 2 by three uniform conduits 8 and welds fixing.Cooling water enters from the water inlet pipe 7 of sleeve 2, discharges from the outlet pipe 9 of core pipe 1, and the water inlet pipe 7 of sleeve 2 is in same end with the outlet pipe 9 of core pipe 1, is convenient at the other end feed arrangement is set.Core pipe 1 outer wall is welded with vertical heat transferring vane 5, sleeve 2 inwalls are welded with vertical conduction vanes 4, and radially be an angle 10 with sleeve 2, partial material slowly can rested on vertical conduction vanes 4 in the rotation for a long time with sleeve 2, thereby increase the area that material contacts vertical conduction vanes 4 and barrel, also this part material is poured on the heat transferring vane 5 of core pipe 1 heat transferring vane 5 on the increase core pipe 1 and the contact area of tube wall and material simultaneously.Sleeve 2 inwalls also are welded with the hoop blade of arranging along the trajectory of helix on circle 3, and the hoop blade 3 of each pitch and the hoop blade interlaced arrangement of last pitch, there is an inclination angle 11 in the cross section that is hoop blade 3 and sleeve 2, make material with sleeve 2 slow rotation central axis to conveying, and can change the axial transporting velocity of material by the size that changes this inclination angle 11.
