Abstract
The utility model provides a full-automatic metering and weighing feeder which relates to a feeder, has simple structure, can continuously and automatically meter total weight of feeding materials of a dry lime slaker, eliminates the influence of negative pressure in a system on a weighing device, and ensures accurate feed. The full-automatic metering and weighing feeder is provided with a bin, a plugboard valve, a feed screw machine, expansion joints, a fully-closed constant feeder, a rotary feeder and a slaker; the plugboard valve is arranged between the discharge hole of the bin and the feed inlet of the feed screw machine; the feed screw machine and the fully-closed constant feeder are connected by the expansion joint, the rotary feeder is arranged at the outlet of the fully-closed constant feeder, the full-closed constant feeder and the rotary feeder are connected by the expansion joint; and the calcium oxide output opening of the rotary feeder is connected with the feed inlet of the slaker. The full-automatic metering and weighing feeder can influence the constant feeder, thus being capable of ensuring accurate, stable and reliable feeding and guaranteeing the reliable operation of the system of the slaker.
Description
Technical field
The utility model relates to a kind of feed arrangement, especially relates to a kind of fully automatic culculating that is mainly used in dry type limeslaker feed arrangement of weighing.
Background technology
At present, the multiple feed arrangement that is used for the dry type limeslaker is arranged on the market, this feed arrangement requires charging stable, can Weighing, but existing most of feed arrangement all is provided with intermediate bunker, if intermediate bunker is bigger, then intermediate bunker material and the corresponding increase of supporting construction material weight, cost performance is relatively poor; If intermediate bunker is less, then can influence the stability and the accuracy of metering, and present computation weigh feed arrangement is automatic metering unloading gross weight continuously mostly, and the Weighing precision is not high mostly, simultaneously because digester inside exists the negative pressure digester negative pressure of about 3000pa also can to change with the variation of electric field boiler negative pressure, so big negative pressure can exert an influence to the charging weighing device, causes the digester fluctuation of service.The operations staff takes to carve and pays close attention to digester ruuning situation, and frequently carries out the adjustment of charging flooding parameter, and automaticity is not high, and the quality of the calcium hydroxide that digestion is come out can't guarantee, even whole digestive system can't normally move.
Summary of the invention
The purpose of this utility model is its digester fluctuation of service of feed arrangement at existing dry type limeslaker, the operations staff takes to carve and pays close attention to digester ruuning situation, and frequently carry out the adjustment of charging flooding parameter, automaticity is not high, the quality of the calcium hydroxide that digestion is come out can't guarantee, even whole digestive system such as can't normally move at problem, provide a kind of simple in structure, can solve the continuous automatic gauge gross weight of charging of dry type limeslaker, negative pressure is to the influence of weighing device in the elimination system, the fully automatic culculating that the guarantees accurate charging feed arrangement of weighing.
The utility model is provided with feed bin, push-pull valve, feeding serew machine, expansion joint, totally-enclosed constant feeder, rotary feeder and digester; Described push-pull valve is located between the charging aperture of the discharging opening of feed bin and feeding serew machine; Rotary feeder is installed in the outlet of totally-enclosed constant feeder, and the calcium oxide delivery outlet of rotary feeder connects the charging aperture of digester.
Can connect by expansion joint between described feeding serew machine and the totally-enclosed constant feeder; Can connect by expansion joint between described totally-enclosed constant feeder and the rotary feeder.
The utility model is according to the feed rate of setting, and by the charging rate of automatic adjusting totally-enclosed constant feeder and feeding serew machine, continuously carries quick lime with assurance, and the quick lime total amount of the automatic cummulative metering conveying of energy.
In addition, rotary feeder is installed in the outlet of totally-enclosed constant feeder, because rotary feeder itself has the effect of lock gas, negative pressure can't be exerted an influence to the totally-enclosed constant feeder, therefore can guarantee accurately, reliablely and stablely charging, ensure the reliability service of digester systems.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
In Fig. 1, respectively be labeled as: 1. feed bin, 2. push-pull valve, 3. feeding serew machine, 4. expansion joint, 5. totally-enclosed constant feeder, 6. rotary feeder, 7. digester.
The specific embodiment
Following examples will the utility model is described in further detail in conjunction with the accompanying drawings.
Referring to Fig. 1, the utility model embodiment is provided with feed bin 1, push-pull valve 2, feeding serew machine 3, expansion joint 4, totally-enclosed constant feeder 5, rotary feeder 6 and digester 7; Described push-pull valve 2 is located between the charging aperture of the discharging opening of feed bin 1 and feeding serew machine 3; Connected by expansion joint 4 between feeding serew machine 3 and the totally-enclosed constant feeder 5, rotary feeder 6 is installed in the outlet of totally-enclosed constant feeder 5, connects with expansion joint 4 between totally-enclosed constant feeder 5 and the rotary feeder 6; The calcium oxide delivery outlet of rotary feeder 6 connects the charging aperture of digester 7.
During manufacturing, earlier feed bin 1, push-pull valve 2, feeding serew machine 3, expansion joint 4, totally-enclosed constant feeder 5, rotary feeder 6, digester 7 are linked up.Link up with expansion joint 4 between feeding serew machine 3 and totally-enclosed constant feeder 5 and totally-enclosed constant feeder 5 and the rotary feeder 6, eliminate the accuracy that system's vibration influence is weighed.
When digester systems started, rotary feeder 6 was opened automatically, and calcium oxide passes through feed bin 1 through push-pull valve 2, feeding serew machine 3, expansion joint 4, totally-enclosed constant feeder 5, rotary feeder 6.Totally-enclosed constant feeder 5 begins to measure the inlet of calcium oxide, feeding serew machine 3 quits work when the inlet of calcium oxide arrives default value, calcium oxide stops charging, feeding serew machine 3 is started working when required calcium hydroxide is lower than default value, calcium oxide begins charging, and so the continuity of calcium oxide charging is guaranteed in circulation.Rotary feeder 6 begins calcium oxide is transported in the digester 7 according to the default rotating speed, and the rotating speed of regulating feeding serew machine 3, totally-enclosed constant feeder 5 and rotary feeder 6 when deviation appears in actual fed amount that calculates when totally-enclosed constant feeder 5 and default value automatically guarantees accurate charging.Because rotary feeder 6 itself has the effect of lock gas, and negative pressure can't be exerted an influence to totally-enclosed constant feeder 5, guarantee accurately, reliablely and stablely charging, ensure the reliability service of digester systems.
