Abstract
The utility model provides a bending water pipe type rotary drum slag cooling machine. The bending water pipe type rotary drum slag cooling machine comprises a machine body and is characterized in that a rotary drum, a cooling device and a rotary drum driving device are arranged in the machine body, one higher end of the rotary drum is connected with a feed pipe, one lower end of the rotary drum is connected with a discharge pipe, the rotary drum is a double-layer round drum, a bending water pipe is welded to the inner wall of the inner-layer round drum, heat exchange fins are welded on the surface of the bending water pipe, a cooling device is arranged outside the rotary drum, the cooling device is water cavity located between the inner-layer round drum and the outer-layer round drum, and one end of the water cavity is connected with the cooling device through a rotary joint. Slag in a drum body of the rotary drum automatically moves to a lower end along with the rotation of the drum body, the abrasion of the slag on the heat exchange fins is reduced, the service life of the heat exchange fins is prolonged, and the stability is good. Meanwhile, the heat exchange area is enabled to be increased, the heat exchange speed is improved, and the work efficiency of the whole cooling system is largely improved.
Description
Technical field
The utility model relates to a kind of boiler combustion waste residue treatment facility, especially a kind of curved waterpipe type barrel slag cooler for the cooling down high-temperature slag.
Background technology
At present, the waste residue after most enterprises use cylinder type cold slag machine to boiler combustion carries out just putting upside down after cooling processing, prevents from discharge sites is produced thermal pollution and causes unnecessary fire hazard.Barrel slag cooler of the prior art, be horizontal positioned, its inner core must push away the slag helical blade, along with the rotation of cylinder is pushed boiler slag to discharging opening from charging aperture by helical blade, wearing and tearing to helical blade are larger like this, cold slag machine used after one to two year needs to change helical blade, wastes time and energy; It is larger that next arranges after helical blade the space in cold slag owner cylinder, and boiler slag can not be full of in cylinder all spaces when cold slag machine operation, causes slag and cylinder cooling device heat exchange area outward little, and the heat transfer rate is slower; At last, drum drive is uniform rotation, and for cooled slag preferably, rotating speed usually can be very slow, so just causes the operating efficiency of whole cooling system lower.
The utility model content
The purpose of this utility model is to provide a kind of curved waterpipe type barrel slag cooler to solve the problems referred to above of the cold slag machine of prior art intermediate roll, and cold slag is effective, cold slag high efficiency, good stability, long service life.
The technical scheme that provides of the present utility model is: a kind of curved waterpipe type barrel slag cooler, comprise body, it is characterized in that: the drum drive that is provided with cylinder, cooling device and head roll in described body, an end and feed pipe that described cylinder is higher join, and an end and discharge nozzle that cylinder is lower join; Described cylinder is double-layered cylinder, the inner layer cylinder inwall is welded with curved water pipe, curved water pipe outer surface is welded with the heat exchange fin, cylinder is outside equipped with cooling device, described cooling device is the water cavity that is between inner layer cylinder and outer cylinder, and an end of described water cavity is connected with chilled water unit by swivel joint.
Preferably, be provided with backpitch envelope slag device between described cylinder and feed pipe.
Preferably, described curved water pipe is around the circumferencial direction arrangement in a row of inner layer cylinder.
Preferably, described curved water pipe is half arc.
The beneficial effects of the utility model are: the utility model cylinder is double-layered cylinder, the inner layer cylinder inwall is welded with curved water pipe, curved water pipe outer surface is welded with the heat exchange fin, the end that cylinder is connected with charging aperture is higher, slag in cylindrical shell can move from the trend low side along with the rotation of cylindrical shell, the wearing and tearing of slag heat exchanging fin have been reduced, the service life of having improved the heat exchange fin, good stability; Heat exchange area is increased, thereby the heat transfer rate speeds, the operating efficiency of whole cooling system improves a lot.

The specific embodiment
Below in conjunction with accompanying drawing, the utility model is described further.
The utility model is a kind of curved waterpipe type barrel slag cooler, comprise body, be provided with cylinder, cooling device and drum drive in body, an end and feed pipe that cylinder is higher join, be provided with backpitch envelope slag device between cylinder and feed pipe, prevent the high temperature sludge seepage, an end and discharge nozzle that cylinder is lower join; Cylinder is double-layered cylinder, the inner layer cylinder inwall is welded with curved water pipe, curved water pipe is half arc, circumferencial direction arrangement in a row around inner layer cylinder, curved water pipe outer surface is welded with the heat exchange fin, cylinder is outside equipped with cooling device, and described cooling device is the water cavity that is between inner layer cylinder and outer cylinder, and an end of water cavity is connected with chilled water unit by swivel joint; Drum drive comprises and rolls band, gear wheel, pinion, motor, reductor and support roller group.
In the present embodiment, the inclination angle of roller tube is 2 °-3 °, slag enters in the cylinder of cold slag machine by feed pipe, cylinder uniform rotation under the drive of drum drive, slag with the rotation of cylinder under Action of Gravity Field, slowly move to the discharge nozzle place, with the contacting of curved water pipe, heat exchange fin and cooling device in heat-shift complete cooling procedure, last cooling slag is discharged from discharge nozzle.
