Abstract
The utility model relates to a kind of improvement of screw feeder, and particularly a kind of tungsten is smelted the adjustable speed double-spiral feeder using in ball milling operation.The utility model comprises spiral shell shell, and a main spiral and a secondary spiral are installed side by side in spiral shell shell, and the rotating blade rotation direction on major and minor spiral is contrary, and major and minor spiral rotating direction is also contrary; Main spiral is driven by adjustable speed adjustable frequency motor, between major and minor spiral, is furnished with pair of engaged gears.The utility model is because the major-minor spiral of two different rotation directions rotates simultaneously, make tungsten concentrate raw material no longer occur " bridging " phenomenon, in spiral shell shell, cannot form " cavity ", raw material energy steady and continuous is supplied with, there is not empty mill phenomenon in ball grinding mill, ore grinding qualification rate improves more than 10%, and production production capacity improves more than 15%, has alleviated the labour intensity of operating personal simultaneously.
Description
Technical field
The utility model relates to a kind of improvement of screw feeder, and particularly a kind of tungsten is smelted the adjustable speed double-spiral feeder using in ball milling operation.
Background technology
In tungsten smelting process, ball milling adopts simple helix feeder feed to material process always, and tungsten concentrate raw material aqueous ingredients is 8% when following, simple helix feed function bio-occlusion material.But along with the minimizing of tungsten concentrate raw material, it is complicated that the source property of tungsten concentrate raw material is tending towards, and the aqueous ingredients in tungsten concentrate raw material is mostly between 10%-12%.At this moment with simple helix feeder feed, there will be feed discontinuous, tungsten concentrate, because moisture is large, easily forms and piles up (being again " bridging " or " cavity " phenomenon) in spiral shell shell, finally cannot bio-occlusion pellet grinding machine ore grinding.Now operating personal must cause feed inhomogeneous by knocking spiral shell shell ability feed, affects ball grinding mill ore grinding qualification rate and efficiency.
Utility model content
The utility model object is to provide a kind of tungsten and smelts the adjustable speed double-spiral feeder using in ball milling operation, realizes continuity and the stability of producing.
Technical solutions of the utility model: a kind of tungsten is smelted the adjustable speed double-spiral feeder using in ball milling operation, comprise spiral shell shell, a main spiral and a secondary spiral are installed side by side in spiral shell shell, and the rotating blade rotation direction on major and minor spiral is contrary, and major and minor spiral rotating direction is also contrary.
Main spiral is driven by adjustable speed adjustable frequency motor, between major and minor spiral, is furnished with pair of engaged gears.
The utility model good effect: because the major-minor spiral of two different rotation directions rotates simultaneously, make tungsten concentrate raw material no longer occur " bridging " phenomenon, in spiral shell shell, cannot form " cavity ", raw material energy steady and continuous is supplied with, there is not empty mill phenomenon in ball grinding mill, ore grinding qualification rate improves more than 10%, and production production capacity improves more than 15%, has alleviated the labour intensity of operating personal simultaneously.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is that double helix of the present utility model is arranged schematic diagram.
In figure: 1 feeding warehouse; 2 adjustable speed adjustable frequency motor and transmission devices; 3 spiral shell shells; 4 discharging openings; 5 portholes; 6 secondary spirals; 7 main spirals; 8 gears.
The specific embodiment
As shown in drawings, the utility model is comprised of feeding warehouse, adjustable speed adjustable frequency motor and transmission device, main spiral, secondary spiral, spiral shell shell, porthole, discharging opening.Adjustable speed adjustable frequency motor, cycloidal planetary gear speed reducer, gear etc. form driving system; A main spiral and a secondary spiral are installed in spiral shell shell side by side, and the rotating blade of major and minor spiral is respectively dextrorotation and left-handed, when transmission device drives main spiral reverse hour hands rotation, secondary spiral under the drive of a pair of gear, clickwise; Enter the material of spiral shell shell under the rotating blade of major and minor spiral promotes, forward continuously and stably feeding.When delivery rate is fast or partially slow, can to adjustable speed adjustable frequency motor rotating speed, regulate by frequency converter, until suitable technique rotating speed.
