Abstract
The utility model discloses a kind of rare-earth mineral rotary kiln special roasting system, comprise and dry rotary kiln and calcination rotary kiln, the feed end of described oven dry rotary kiln arranges vibratory screening apparatus feeding unit, the discharge end of drying rotary kiln arranges the first material-pumping tube, first material-pumping tube is arranged the first sack cleaner and the first sack cleaner blower fan, first sack cleaner discharge port connects screw feeder, screw feeder connects the feed end of calcination rotary kiln, the discharge end of calcination rotary kiln arranges the second material-pumping tube, second material-pumping tube is arranged the second sack cleaner and the second sack cleaner blower fan.This is practical by the global optimization to existing rotary kiln baking system, thus improve the working strength of operating environment and reduction operator, manually-operated link in the middle of also being reduced by Automated condtrol, is reduced the intermediate consumption of material, thus increases work efficiency.
Description
Technical field
The utility model belongs to field of metallurgy, is specifically related to a kind of rare-earth mineral rotary kiln special roasting system.
Background technology
The incoherent situation of linking is there is at present more in the continuous use of rare-earth trade multiple stage multilevel rotary kiln sinter process, in most cases there is the situation that people is transfer, because rare-earth original ore humidity is larger, during charging, most mode of artificial spade material that adopts carries out charging, after oven drying at low temperature, carrying out high-temperature roasting by manually dropping into an other rotary kiln after being collected by artificial pack again, after roasting completes, manually carrying out pack of weighing.Adopt the mode of the charging of artificial spade material and centre, end rewinding pack, workman's workload is comparatively large, and under Rare-Earth Magnetic floats ore deposit ore particle granularity simultaneously, after roasting, artificial turning in the process of material and pack easily produces airborne dust, causes mineral aggregate loss large.In the process of manual operation simultaneously, workman's safety appliance dresses irregular words, easily causes the health of human body problems such as silicosis to operator.
Also have now some to adopt standard machinery charging or spiral feeding manner to carry out charging, but due to rare-earth original ore high humidity, aforesaid way usually can cause feed path blocked and cause shutdown process.
Summary of the invention
The object of the invention is to provide a kind of rare-earth mineral rotary kiln special roasting system, and solving existing roasting system can not continuous mechanized cause labour intensity large, easily produces airborne dust, causes the problem of mineral aggregate loss.
Technical scheme of the present invention is: rare-earth mineral rotary kiln special roasting system, comprise and dry rotary kiln and calcination rotary kiln, the feed end of described oven dry rotary kiln arranges vibratory screening apparatus feeding unit, the discharge end of drying rotary kiln arranges the first material-pumping tube, first material-pumping tube is arranged the first sack cleaner and the first sack cleaner blower fan, first sack cleaner discharge port connects screw feeder, screw feeder connects the feed end of calcination rotary kiln, the discharge end of calcination rotary kiln arranges the second material-pumping tube, second material-pumping tube is arranged the second sack cleaner and the second sack cleaner blower fan.
Further, described second material-pumping tube is provided with blast inlet.
In roasting system of the present utility model, the feed end of drying rotary kiln adopts vibratory screening apparatus feeding unit, effectively can solve the feed path caused due to rare-earth original ore high humidity blocked and cause the problem of shut-down.Drying rotary kiln tentatively dry after the movement system that formed by the first material-pumping tube, the first sack cleaner and the first sack cleaner blower fan of material be given to screw feeder, material is proceeded to calcination rotary kiln and carries out roasting by screw feeder again, and roasting material is collected by the material-receiving system consisted of the second material-pumping tube, the second sack cleaner and the second sack cleaner blower fan after roasting completes.
Second material-pumping tube road leaves blast inlet, carrying out in the process that material pumps suction cold wind in the lump, material can be made to cool fast, decrease the naturally cooling time.Automatic packaging can be realized.
The present invention compared with prior art tool has the following advantages:
This is practical by the global optimization to existing rotary kiln baking system, thus improve the working strength of operating environment and reduction operator, manually-operated link in the middle of also being reduced by Automated condtrol, is reduced the intermediate consumption of material, thus increases work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, Reference numeral is: 1-vibratory screening apparatus feeding unit, 2-dries rotary kiln, 3-first material-pumping tube, 4-first sack cleaner, 5-first bag-type dust blower fan, 6-screw feeder, 7-calcination rotary kiln, 8-enters cold wind mouth, 9-second material-pumping tube, 10-second sack cleaner, 11-second bag-type dust blower fan.
Embodiment
Embodiment 1
As shown in Figure 1, rare-earth mineral rotary kiln special roasting system, comprise and dry rotary kiln 2 and calcination rotary kiln 7, the feed end of described oven dry rotary kiln 2 arranges vibratory screening apparatus feeding unit 1.The discharge end of drying rotary kiln 2 arranges on the first material-pumping tube 3, first material-pumping tube 3 and arranges the first sack cleaner 4 and the first sack cleaner blower fan 5.First sack cleaner 4 discharge port connects screw feeder 6, and screw feeder 6 connects the feed end of calcination rotary kiln 7.The discharge end of calcination rotary kiln 7 arranges on the second material-pumping tube 9, second material-pumping tube 9 and arranges the second sack cleaner 10 and the second sack cleaner blower fan 11.
Embodiment 2
This embodiment is substantially the same manner as Example 1, and difference is to be provided with blast inlet on the second material-pumping tube 9.Carrying out in the process that material pumps suction cold wind in the lump, material can be made to cool fast, decrease the naturally cooling time.Automatic packaging can be realized.
The above embodiment only have expressed the embodiment of the application, and it describes comparatively concrete and detailed, but therefore can not be interpreted as the restriction to the application's protection domain.It should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from technical scheme design, can also make some distortion and improvement, these all belong to the protection domain of the application.
