Technical field
The utility model relates to the discontinuous quantifying feed of a kind of spiral system, belongs to solid material feeding technique field, quantifying feed when being used for solid material batching and packing.
Background technology
Discontinuous quantitatively is the important production links of a large amount of powder grain materials, like finished product or half-blanks such as powdered metal parts, pottery, building materials, chemical, and quantitative ingredient that fertilizer and pesticide and agricultural byproducts carry out and quantitative package etc.The discontinuous quantitative tradition of powder has positive displacement and weighing formula; Novel have hybrid and compound type; Their common ground are all by feeding in raw material, measure and three parts that feed intake being formed; On the one hand reinforced to measuring container or weighing scale through the system controlled by computer charger, carry out Measuring and testing according to volume or requirements for quality on the other hand, reach and stop reinforced after the requirement and feed intake.Coordinate between three parts to require height, time-consuming, work efficiency is lower; Equipments overall structure is complicated, and the fine silt material is prone to the moisture absorption bonding, adsorbs and splashes, and quantitatively receives environment and structure influence big, and ejecta pollution causes that occupational diseases such as pneumoconiosis, chemicals poisoning are serious.Research realizes that the discontinuous quantifying feed of powder is thoroughly to solve one of discontinuous quantitative difficult problem effective ways, also is one of quantitatively main developing direction of powder.
At present the reinforced form of powder has spiral, oscillatory type, belt-type, flow by gravity formula and pressure type etc. angrily.Wherein, screw feeding is passed material forward along hopper through the helicallobe rotation, has advantages such as simple in structure, that leak tightness is strong, flow control is convenient, is widely used in powder and the fritter shape mass transport or the continuous charging of anti-extruding.Multiple reinforced form comparative analysis is found: screw feeding more is prone to realize quantifying feed control, and can reduces cross pollution between human body and powder, powder and the powder.This is even more important to food, medicine and the safety in production of poisonous and harmful material.
Although conveyor screw was invented by Archimedes before bimillennium greatly as water lift, as the also existing one-hundred-year history of conveying, lifting and the handler of bulk solid material in the industrial or agricultural..Add (give) material machine but just have the researchist to develop quantitative spiral abroad, and wash on the purified salt manufacturing line at powder and to be applied according to the conveyor screw principle up to the nineties in last century.Quantitative spiral is added the research of (giving) material machine; External representativeness has: Y.
