Abstract
The invention discloses a condenser of a rotary kiln, which is characterized in that: the condenser (1) is a stepped waterwheel type structure; a water wheel type zinc containing bucket (5) is arranged at a place of the condenser (1), which is close to an external cylinder of the rotary kiln (4); the zinc containing bucket (5) is provided with steps (6) which are applied to falling, splashing, forward and backward movements of zinc solution; a delivery and pre-heating rotary cylinder (2) is arranged in the middle of the condenser (1); and a metallic solution automatic overflow device (3) is arranged below the condenser (1). The condenser of the rotary kiln disclosed by the invention meets the demands of efficiency, energy saving, environment protection, material consumption saving, and the like, and is suitable for smelting processes which smelt metals in a format of the rotary kiln and condense and recycle in a format of metal vapor.
Description
Technical field
The present invention relates to a kind of metal melting equipment, particularly a kind of rotary kiln condensing surface belongs to technical field of non-ferrous metallurgy.
Background technology
The condensing surface of existing pyrometallurgical smelting zinc, most driven by motor graphite rotators that adopt, high-speed motion, the zinc rain condensation of kicking up, its advantage is that condensation effect is better; It is big that shortcoming is that graphite rotator is raised in the zinc attrition at a high speed, needs often to change, and both influenced output during replacing, increases the oxidation of zinc again; Simultaneously thermal discharge is big during zinc vapor condensation, can not get recycling.
Summary of the invention
Technical problem to be solved by this invention be to provide a kind of condensation effect better and the zinc vapor condensation heat radiation can be by the rotary kiln condensing surface of better recycling, thereby overcome the deficiency of above-mentioned prior art.
For solving the problems of the technologies described above, the present invention adopts following technical scheme: a kind of rotary kiln condensing surface.This condensing surface is a scalariform water wheel type structure, leans on rotary kiln outer cylinder body place to be provided with water wheel type at condensing surface and contains the zinc bucket, on Sheng Xindou, is provided with to be used for the ladder that zinc liquid falls to splashing and seesaw; Be provided with defeated material and preheating rotating cylinder in the centre of condensing surface, below condensing surface, be provided with molten metal and overflow device automatically.
Above-mentioned rotary kiln condensing surface, described condensing surface and rotary kiln are connected in one.
Aforesaid rotary kiln condensing surface, described condensing surface are to adopt silicon nitride or carbofrax material to be made.
Beneficial effect of the present invention: compared with prior art, the present invention has following characteristics: (1) condensing surface has adopted waterwheel to add stepped unique texture design, and defeated material and preheating rotating cylinder are set in the middle of condensing surface; It is more abundant that liquid metal is seesawed up and down, and the impact of splashing down is little, and the drop that splashes down is more even; Increased material structure intensity; Also make the condenser temperature distributing equilibrium, make the zinc fume just can fast cooling, obtain high-efficiency condensation in the ingress; Improved condensation effect greatly; And in the process of chills steam, can simultaneously its heat be passed to material, thus reaching the best thermal utilization effect of limit condensation side preheating, the zinc vapor condensation heat radiation has obtained recycling preferably.(2) lean on rotary kiln outer cylinder body place that water wheel type is set at condensing surface and contain the zinc bucket, raise the zinc device with low speed and replaced the high speed of prior art to raise the zinc device, raise the wearing and tearing of zinc device and lack, but life-time service.(3) Sheng Xindou is provided with and is used for the ladder that zinc liquid falls and to splash and to seesaw, and liquid zinc splashes up and down in condensing surface and seesaws, and can make the condenser temperature distributing equilibrium, makes the zinc fume just can fast cooling in the ingress, obtains condensation effect efficiently.(4) replace traditional graphite material to make condensing surface with silicon nitride or carbofrax material, wear resistance is good, the life-span is long.(5) condensing surface and rotary kiln are connected in one, and resistance to air loss is good, and it is few that zinc fume reoxidizes probability, and direct yield is high.
Requirements such as the present invention meets efficiently, energy-saving and environmental protection, economical with materials consumption are fit to rotary kiln form metal smelting and with the smelting technology of metal vapors condensing and recycling.

Embodiment
Embodiment 1.As shown in Figure 1, condensing surface 1 is installed in the rotary kiln 4 and with rotary kiln 4 and is connected in one.As shown in Figure 2; This condensing surface 1 adopts scalariform water wheel type structure; Lean on rotary kiln 4 outer cylinder body places to be provided with water wheel type at condensing surface 1 and contain zinc bucket 5, be used for the ladder 6 that zinc liquid falls to splashing and seesaw containing to be provided with on the zinc bucket 5, condensing surface 1 adopts silicon nitride or carbofrax material to make.Be provided with the defeated material and the preheating rotating cylinder 2 that are used to carry smelting material and material are carried out preheating in the centre of condensing surface 1.Below condensing surface 1, be provided with molten metal and overflow device 3 (as shown in Figure 3) automatically, this molten metal overflows device 3 automatically can will be contained the rich zinc liquid that zinc bucket 5 can not load automatically and extruded outside the rotary kiln 4 through the automatic hydraulic mode by zinc outlet in the rotary course of rotary kiln 4.
Embodiment of the present invention is not limited to the foregoing description, and the various variations of under the prerequisite that does not break away from aim of the present invention, making all belong within protection scope of the present invention.
