Description
Technical field
The present invention relates to a kind of filtration and metering device of mixing plant powder.
Background technology
Powder is stored in filler bin, by screw machine by powder carry in powder metering bucket, weight is converted to the signal of telecommunication and delivers to Weighting and Controlling instrument and carry out Weighting and Controlling by the sensor of scale hooper bottom, owing to continuing after the power-off of effect of inertia screw machine to rotate, the size of the anglec of rotation is subject to the fluctuation of voltage, the viscosity of powder, screw machine lubricating status, the impact of abrasion condition, due to the fluctuation of voltage, the viscosity of powder, screw machine lubricating status, abrasion condition enchancement factor is more, make screw machine inertia output powder uncontrollable, thus cause actual drop value to change greatly, setting drop value frequently revised by Weighting and Controlling instrument, result is that each weight of material total amount of polydisc concrete mix does not exceed standard, but each weight of material of single-deck concrete mix exceeds standard, serious has had influence on concrete quality.In addition, powder often there will be the foreign material such as bolt, iron ball, stone when entering conveying worm, and these foreign material gently then cause vexed machine to stop in conveying worm, heavy then damage conveying worm blade or motor damage.For this situation, for ensureing that the powder of filler bin is not containing foreign material, at filler bin charging aperture place, a powder filter is installed, its structure is exactly that a middle part diameter is large, the pipeline that upper and lower position diameter is little, is provided with a double-edged fine-toothed comb in the middle of pipeline, that is, powder filter is exactly that a centre is thick thin up and down, is provided with the pipeline of double-edged fine-toothed comb in centre.This filter in use; if double-edged fine-toothed comb mesh is excessive; do not have the effect of filtration; if mesh is overstocked; again often can because foreign material be attached under the influence of air pressure on double-edged fine-toothed comb and cause clogging; cleaning gets up not only to bother but also lose time, and not only extends the activity duration, also there is the potential safety hazard of booster because double-edged fine-toothed comb clogging causes air pressure too high.
Summary of the invention
The present invention, in order to overcome the deficiencies in the prior art, provides a kind of filtration and metering device of mixing plant powder.
For achieving the above object, the technical solution used in the present invention is: it comprises filler bin, filter, screw machine and Weighing system, the top of filler bin is provided with charging aperture, and charging aperture place is provided with filter, screw machine outlet connects Weighing system, Weighing system comprises Weighting and Controlling instrument and scale hooper, scale hooper bottom is provided with LOAD CELLS, the Pneumatic butterfly valve with screw machine outlet diameter adaptation is provided with in screw machine exit, Pneumatic butterfly valve gas circuit is provided with two five-way electromagnetic valves, the control signal wire of two five-way electromagnetic valves connects screw machine contactor, described filter is made up of center filter pipeline and spiral hollow body, spiral hollow body top is provided with a feeding mouth, bottom is provided with a slag-drip opening and a slag-drip opening gland, the body body of spiral hollow body is provided with opening, its opening surface is centered around on the tube wall of center filter pipeline, spiral hollow body and center filter pipeline are integrated, the center filter pipe wall combined with spiral hollow body body body opening surface is provided with several filter bores, the lower end of center filter pipeline is provided with an inspection socket and an inspection socket gland, its upper end is the discharging opening connected with the charging aperture of filler bin.
Further, the bottom of described Pneumatic butterfly valve connects lower connector, and described lower connector is connected with snake-like hose, and snake-like hose connects Weighing system.
The present invention has following beneficial effect: after the present invention adopts Novel measuring device, actual drop value is only exported to the impact of elevation and the change of powder proportion between scale hooper powder surface by screw machine, and screw machine is exported to elevation between scale hooper powder surface is fixing, the change of powder proportion is very little, thus actual drop value change is very little, ensure actual drop value and set the error of drop value in drop extent of amendment, effectively eliminating the impact of screw machine on actual drop value.The present invention is applicable to HZS type concrete mixing plant powder metering; Foreign material can effectively be separated with powder by filter, and significantly improve operating efficiency, and because foreign material are effectively separated with powder, the filter area of design is large, solves blockage problem, effectively avoids work risk.
