Abstract
The utility model discloses a rotary kiln. The rotary kiln comprises a barrel. A heating device is arranged on the barrel. A feeding port and a discharge port are formed in the side wall of the barrel. A thermal insulation mechanism is arranged on the inner wall of the barrel and comprises a fire-proof layer and a thermal insulation layer. The thermal insulation layer is arranged between the fire-proof layer and the inner wall of the barrel. The fire-proof layer comprises a plurality of firebricks closely attached to the thermal insulation layer. Locating grooves are formed in the two sides of each firebrick respectively. Locating columns are inserted between the firebricks after the firebricks are matched. A partition plate used for buffering impact force applied by materials on the inner wall of the barrel is arranged in an inner cavity of the barrel and is provided with a plurality of through holes. By adopting the technical scheme, the rotary kiln has higher thermal efficiency, and heat will not be easily dissipated; meanwhile, by the arrangement of the partition plate, the impact force applied by the materials in the rotary kiln on the inner wall of the barrel can be reduced and can act on the partition plate, the service life of the firebricks is longer, and maintenance cost is reduced.
Description
[technical field]
The utility model relates to a kind of metallurgical equipment, particularly a kind of rotary kiln for titanium-iron powder, titanium white production.
[background technology]
Existing rotary kiln, because it is simple in structure, insulation and the heat-resisting effect of the thermal-insulation heat-resistant layer that it is inner are poor, cause the thermal efficiency low, meanwhile, the easy damage equipment of material in revolution, so maintenance cost is high, thus increased operation cost.
[utility model content]
Problem to be solved in the utility model is to provide a kind of rotary kiln, can be more energy-conservation, and its internal structure is firmer, and easy to maintenance, materiel machining efficiency is high.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of rotary kiln, comprise cylindrical shell, described cylindrical shell is provided with heater, described cylinder lateral wall is provided with feeding mouth and discharging opening, described cylinder inboard wall is provided with heat-shield mechanism, described heat-shield mechanism comprises flame retardant coating and heat-insulation layer, described heat-insulation layer is located between described flame retardant coating and described cylinder inboard wall, described flame retardant coating comprises some refractory brick and is close on described heat-insulation layer, described refractory brick both sides are respectively equipped with detent, between refractory brick after described cooperation, be all fitted with locating dowel, described cylinder lumen is provided with for alleviating the division board of material to described cylinder inboard wall impulsive force, on described division board, offer some through holes.
Improved, described division board is two refractory slabs, and described refractory slab two ends are separately fixed on cylinder inboard wall, described refractory slab cross one another and the central shaft of crossover location and described cylindrical shell overlapping.
Improved, described refractory slab intersecting angle is 90 degree.
Improved, the material of described heat-insulation layer is asbestos shingle.
Improved, the material of described locating dowel is pottery.
The beneficial effects of the utility model:
In the utility model, refractory brick is reinforced by detent, and and between cylindrical shell, add heat-insulation layer, make the location of refractory brick more firm, be not easy to produce the problem that refractory brick drops in rotary kiln turning course, meanwhile, in maintaining, directly the locating dowel in detent is taken out, can change refractory brick.Meanwhile, division board is set in cylindrical shell, adopts after technique scheme, make this device thermal efficiency higher, the life-span is longer, is not easy to make heat loss.Meanwhile, the setting of division board, can make to reduce material in the revolution impulsive force to cylinder inboard wall, make impact force action in division board, material through reduction of speed is turned round between each division board by through hole again, makes the longer service life of rotary kiln, has reduced maintenance cost.
These features of the present utility model and advantage will be below the specific embodiment, accompanying drawing in detailed exposure.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further:
Fig. 1 is the structural representation of a kind of rotary kiln of the utility model;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
[specific embodiment]
The utility model provides a kind of rotary kiln, comprise cylindrical shell, described cylindrical shell is provided with heater, described cylinder lateral wall is provided with feeding mouth and discharging opening, described cylinder inboard wall is provided with heat-shield mechanism, described heat-shield mechanism comprises flame retardant coating and heat-insulation layer, described heat-insulation layer is located between described flame retardant coating and described cylinder inboard wall, described flame retardant coating comprises some refractory brick and is close on described heat-insulation layer, described refractory brick both sides are respectively equipped with detent, between refractory brick after described cooperation, be all fitted with locating dowel, described cylinder lumen is provided with for alleviating the division board of material to described cylinder inboard wall impulsive force, on described division board, offer some through holes.Refractory brick is reinforced by detent, and and cylindrical shell between add heat-insulation layer, meanwhile, division board is set in cylindrical shell, adopt after technique scheme, make this device thermal efficiency higher, be not easy to make heat loss.Meanwhile, the setting of division board, can make to reduce material in the revolution impulsive force to cylinder inboard wall, makes impact force action in division board, makes the life-span of refractory brick longer, reduces maintenance cost.
