Description
Technical field
The utility model relates to a kind of filtration and metering device of mixing plant powder.
Background technology
Powder is stored in filler bin, by screw machine, powder is transported in powder metering bucket, under scale hooperThe sensor of portion is converted to the signal of telecommunication by weight and delivers to Weighting and Controlling instrument and carry out Weighting and Controlling, due to effect of inertiaAfter screw machine power-off, continue rotation, the size of the anglec of rotation is subject to viscosity, the screw machine of the fluctuation of voltage, powderThe impact of lubricating status, abrasion condition, due to the viscosity of the fluctuation of voltage, powder, screw machine lubricating status,Abrasion condition enchancement factor is more, makes screw machine inertia output powder uncontrollable, thereby causes realityBorder drop value changes greatly, and Weighting and Controlling instrument is frequently revised and set drop value, and result is polydisc concrete match ratioDo not exceed standard than each weight of material total amount, but the each weight of material of single-deck concrete mix exceeds standard, serious impactArrive concrete quality. In addition, powder often there will be bolt, iron ball, stone in the time entering conveying wormSon waits foreign material, and these foreign material gently cause vexed machine to stop in conveying worm, heavy damage conveying wormBlade or motor damage. For this situation, for the powder that ensures filler bin does not contain foreign material, enter at filler binA powder filter is installed at a material mouthful place, and its structure is exactly that a middle part diameter is large, upper and lower position straightThe pipeline that footpath is little, is provided with a double-edged fine-toothed comb in the middle of pipeline, that is to say, powder filter is exactly a centreSlightly thin up and down, be provided with the pipeline of double-edged fine-toothed comb in centre. This filter in use, if double-edged fine-toothed comb mesh mistakeGreatly, do not have the effect of filtration, if mesh is overstocked, again often can be because foreign material paste under the effect of air pressureOn double-edged fine-toothed comb, cause mesh to stop up, cleaning gets up not only to bother but also lose time, and has not only extended the activity duration,Also exist the potential safety hazard that causes the too high booster of air pressure because of the obstruction of double-edged fine-toothed comb mesh.
