Abstract
The utility model relates to a feeding device of a screw conveyer, which eliminates the defects of disc feeder and ensures the continuous uniform feeding by changing the delivery and feeding method of the zinc-oxide calcine. The feeding device comprises a silo and is characterized in that a star-shaped feeder is connected below the silo, and a screw conveyer is arranged below the star-shaped feeder. The star-shaped feeder is used for replacing the disc feeder and the screw conveyer is used for replacing the chute for delivery so as to form a new equipment flow; and the silo, the star-shaped feeder, the screw conveyer and the ball mill have the advantages of effectively solving the problems that the zinc-oxide calcine is blocked and stuck in the feeder and the chute is blocked.
Description
Technical field
The utility model relates to a kind of blanking by the change zinc-oxide calcine and carries feed-type, eradicates the disadvantage of disk feed, guarantees the helical feed charging gear of continuous even feeding.
Background technology
In the zinc hydrometallurgy industry, the intrinsic equipment flowsheet of zinc oxide operation feeding system is: feed bin → plate feed → chute → ball grinding mill, zinc-oxide calcine is delivered to plate feed from feed bin, give by disk again and expect chute, in chute, lean on washing away of supernatant liquid, enter ball grinding mill with liquid; But in the process of this feed, have following problem: 1, the easy oxidized zinc calcine of plate feed stops up stuck; 2, zinc-oxide calcine very easily crystallizes into piece in chute, stops up chute; 3, there is inspection door the plate feed top, in the blanking process, follows a large amount of dust, and workshop condition is abominable; 4, the disk feed does not have automatic gauge, and the blanking amount can not accurately be controlled.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of zinc-oxide calcine that can effectively solve to stop up stuck phenomenon and the helical feed charging gear that stops up the chute phenomenon in feeder.
The purpose of this utility model is achieved in that and comprises and it is characterized in that feed bin: connecting below feed bin has star-like feeder, is provided with conveyor screw below star-like feeder.Replace plate feed with star-like feeder, replace chute to carry, form new equipment flowsheet: feed bin, star-like feeder, conveyor screw, ball grinding mill with helical feed.
Effective effect of the present utility model is:
1, star-like feeder replaces plate feed, has solved zinc-oxide calcine and stop up stuck phenomenon in feeder;
2, replace chute to carry with helical feed, solved zinc-oxide calcine and in chute, crystallized into piece, stop up the phenomenon of chute
3, the transformation of delivery system is strengthened whole charging gear leak tightness, and dust can not fill the air everywhere, has improved workshop condition greatly.
4, helical feed has autonomous cruise speed system, and the blanking amount is able to accurate metering.
Description of drawings
Fig. 1 is a constructional drawing of the present utility model.
The specific embodiment
The structure of the utility model before transformation is: feed bin, plate feed and transporting chute.At first, zinc-oxide calcine is delivered to plate feed from feed bin, and calcining is in the plane motion of disk, be transported to discharging opening, the calcining that will be coiled by a scraping blade scrapes, and is transported in the chute, by the washing away of supernatant liquid, calcining enters next procedure with supernatant liquid again---ball grinding mill.But in the feed process, if the calcining that feed bin receives just is easy to be combined into piece in feed bin not through fully dry, during blanking, a large amount of block calcinings fall into plate feed together, and weight all is pressed on the disk, and the disk load-bearing exceeds load and is stuck.Simultaneously, become block calcining to kill disk after, continue to fall to transporting chute by the feeder discharging opening, moment is stifled full with chute, and after getting lodged in calcining and supernatant liquid mixing in the chute, crystallizes into hard material piece immediately, stops up chute, is difficult to clear up.And in the blanking process, the disk unloader does not have self-measuring device, and by manual shift, the blanking amount can't accurately be measured; The leak tightness of charging gear is bad again, causes dust to fill the air, and workshop condition is abominable.
As shown in Figure 1, after the utility model was transformed, 1 was feed bin, and 2 is star-like feeder, and 3 is conveyor screw.At first, zinc-oxide calcine is delivered to star-like feeder from feed bin, a plurality of scraping blades in the star-like feeder are by directed uniform rotation, calcining is slowly scraped, enter conveyor screw, by helical feed, under the situation of automatic guidance operational throughput, zinc-oxide calcine quantitatively enters next operation---ball grinding mill.If when situation same before transforming occurring (calcining in the feed bin is formed bulk and fallen), can not be stuck moment in the star-like feeder, by the continuous running of a plurality of scraping blades, the calcining that drops in the feeder can evenly scrape with scraping blade, falls into spiral.And this moment, supernatant liquid washed away during the helical feed calcining replaced, and in one section course of conveying before entering ball grinding mill, had avoided the mixing of solid-liquid, and the phenomenon that does not also just have crystallization has occurred.And in the blanking process, screw feeder has automatic gauging device.Do not need manual shift blanking amount, just can realize dosing.
