Abstract
The invention discloses a rotary kiln which comprises a barrel. The barrel is provided with a heating device, a feeding opening and a discharging opening are formed in the side wall of the barrel, and a thermal insulation mechanism is arranged on the inner wall of the barrel. The thermal insulation mechanism comprises a flame retardant coating and an insulating layer. The insulating layer is arranged between the flame retardant coating and the inner wall of the barrel. The flame retardant coating comprises a plurality of refractory bricks and is tightly attached to the insulating layer, positioning grooves are formed in the two sides of each refractory brick respectively, and positioning pillars can be inserted into the gaps between the matched refractory bricks. An isolation plate used for relieving the impact force of materials to the inner wall of the barrel is arranged in an inner cavity of the barrel, and the isolation plate is provided with a plurality of through holes. According to the technical scheme, thermal efficiency is higher, and heat is not likely to be lost; meanwhile, due to the arrangement of the isolation plate, the impact force of the materials in the rotary kiln to the inner wall of the barrel can be lowered, the impact force can act on the isolation plate, the service life of the refractory bricks is longer, and the maintenance cost is lowered.
Description
[technical field]
The present invention 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 its structure is simple, insulation and the heat-resisting effect of the thermal-insulation heat-resistant layer of its inside are poor, cause the thermal efficiency low, and meanwhile, the easy damage equipment of the material in revolution, therefore maintenance cost is high, thus adds operation cost.
[summary of the invention]
The problem to be solved in the present invention is to provide a kind of rotary kiln, can be more energy-conservation, and its internal structure is firmer, easy to maintenance, and materiel machining efficiency is high.
In order to solve the problems of the technologies described above, the present invention 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, all locating dowel is fitted with between refractory brick after described cooperation, described cylinder lumen is provided with for alleviating the division board of material to described cylinder inboard wall impulsive force, described division board offers some through holes.
Improve, described division board is two pieces of refractory slabs, and described refractory slab two ends are separately fixed on cylinder inboard wall, and described refractory slab crosses one another and crossover location is overlapping with the central shaft of described cylindrical shell.
Improve, described refractory slab intersecting angle is 90 degree.
Improve, the material of described heat-insulation layer is asbestos shingle.
Improve, the material of described locating dowel is pottery.
Beneficial effect of the present invention:
In the present invention, refractory brick is reinforced by detent, and and add heat-insulation layer between cylindrical shell, make the location of refractory brick more firm, be not easy the problem that generation refractory brick drops in rotary kiln turning course, meanwhile, when maintaining, directly the locating dowel in detent is taken out, can change refractory brick.Meanwhile, arrange division board in cylindrical shell, after adopting 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, the material during reduction can be made to turn round is to the impulsive force of 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, reduces maintenance cost.
These features of the present invention and advantage will detailed description of the invention below, exposure detailed in accompanying drawing.
[accompanying drawing explanation]
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
Fig. 1 is the structural representation of a kind of rotary kiln of the present invention;
Fig. 2 is the partial enlarged drawing at A place in Fig. 1.
[detailed description of the invention]
The invention 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, all locating dowel is fitted with between refractory brick after described cooperation, described cylinder lumen is provided with for alleviating the division board of material to described cylinder inboard wall impulsive force, described division board offers some through holes.Refractory brick is reinforced by detent, and and add heat-insulation layer between cylindrical shell, meanwhile, in cylindrical shell, division board is set, after adopting technique scheme, makes this device thermal efficiency higher, be not easy to make heat loss.Meanwhile, the setting of division board, the material during reduction can be made to turn round, to the impulsive force of cylinder inboard wall, makes impact force action in division board, makes the life-span of refractory brick longer, reduces maintenance cost.
