Abstract
The utility model discloses a multitube roller slag cooler with shaftless spiral heat exchange tubes. The multitube roller slag comprises a roller and a motor for driving the roller, wherein one end of the roller is provided with a discharge device and a rotary joint while the other end of the roller is provided with a feeding device and a returning device, a hollow rotating shaft is arranged at the center in the roller, the plurality of heat exchange tubes are rotationally distributed by taking the central axis of the hollow rotating shaft as a center of rotation, connection pipelines are arranged for connecting the hollow rotating shaft and the heat exchange tubes, the hollow rotating shaft is provided with a water inlet and a water outlet communicated with the inner cavity of the hollow rotating shaft, and a rotary support ring is arranged between the outer sides of the heat exchange tubes and the roller. The multitube roller slag cooler with shaftless spiral heat exchange tubes adopts the design of heat exchange tubes arranged in the shape of plum blossom instead of the traditional design of screw blades, thus being capable of effectively improving load carrying capacity of slag cooler, more rapid in rate of rotation and higher in heat exchange efficiency.
Description
Technical field
The utility model relates to a kind of barrel slag cooler, especially relates to a kind of multitube barrel slag cooler of shaftless spiral heat exchange tube.
Background technology
In known technical field, cold slag machine is the energy saving environmental protection product that country advocates energetically and encourages, the red slag up to more than 950 DEG C temperature that boiler is discharged is cooling by two medium circulation of water and wind, after reducing the temperature to 60 DEG C～80 DEG C, produce cement as clinker, cooling water used enters boiler again and produces steam after absorption heat temperature is brought up to 85 DEG C～95 DEG C.Air also enters boiler combustion system barrel slag cooler as a kind of common boiler auxiliaries through absorbing after heat improves temperature, be used for the lime-ash after boiler combustion to carry out cooling processing, to its waste heat and lime-ash are recycled, and along with the improving constantly of working strength, people also have higher requirement for the serviceability of barrel slag cooler.Existing cold slag machine structure is roughly to have a hollow shaft with helical blade in the housing sealing, in axle and in blade, lead to cooling water, the warm sludge that boiler is discharged drives the rotation of helical blade to promote lime-ash by hollow shaft and moves, heat transmission feedwater warm sludge being discharged in progradation, thereby reach object cooling lime-ash, and the load that helical blade can bear is little, cause the efficiency of heat exchange not high, contact area is also limited.
Utility model content
Technical problem to be solved in the utility model is: a kind of multitube barrel slag cooler of shaftless spiral heat exchange tube is provided, can improves the heat exchanger effectiveness of cold slag machine, improve cooling effect and load-bearing ability.
For solving the problems of the technologies described above, the technical solution of the utility model is:, a kind of multitube barrel slag cooler of shaftless spiral heat exchange tube, comprise the motor (2) of cylinder (1) and head roll (1), be provided with drawing mechanism (3) and swivel joint (4) in one end of described cylinder (1), be provided with feed arrangement (5) and material-returning device (6) at the other end of described cylinder (1), it is characterized in that: be provided with hollow turning cylinder (7) at described cylinder (1) Nei center, central axis taking described hollow turning cylinder (7) is distributed with several heat exchanger tubes (8) as pivot rotates, between described hollow turning cylinder (7) and heat exchanger tube (8), be provided with connecting line, on described hollow turning cylinder (7), be provided with water inlet and delivery port with the intracavity inter-connection of hollow turning cylinder (7), between the outside of described heat exchanger tube (8) and cylinder (1), be provided with rolling support ring (9), heat exchanger tube has shaftless spiral in (8).The quantity of described heat exchanger tube (8) is 6-54 root.The beneficial effects of the utility model are: changed the design of traditional helical blade type, adopted the design of the heat exchange tubular type that is plum blossom shape, can effectively improve the load-bearing ability of cold slag machine, made slewing rate faster, heat exchanger effectiveness is higher.
Heat exchanger tube two ends welding makes spiral expanded by heating be close to heat exchanger tube inwall, has increased area of dissipation, significant prolongation service life.
