Description
Technical field
It the utility model is related to a kind of storing, feeding-distribution device, and in particular to integral type calcium carbonate storing, feeding-distribution device.
Background technology
Carpet is made up of carpet surface, base portion, secondary base fabric and high-strength polymer, and what so-called high-strength polymer referred to is exactly
" glue ", industrial this " glue " refer to the mixture mainly with calcium carbonate and adhesive, master of the calcium carbonate in adhesive
It is gel filled, increase colloid viscosity to act on, different product, its proportionings of different manufacturers difference.It is big in factory at present
It is more to be used for downstream workshop using manually carrying packed calcium carbonate, can not realize that batch dispenses, such case be mainly by
Caused by following reason.
First, compared to industrial other powders easily fluidized such as talcum powder, cement, the mobility of technical calcium carbonate
It is relatively poor, accumulation is easily formed, particularly industrial carbon calcium also has certain water absorption rate, and the change of ambient humidity easily causes
The moisture absorption water suction of material makes its mobility more weaken, be stored in calcium carbonate in storage tank bottom accumulation can not smooth blanking,
Storage tank is caused to use paralysis.The reason for causing solid accumulation not get off smoothly mainly due to different physico-chemical properties powder its
It is for evaluating powder flowing performance that mobility, which has very big difference, general angle of repose, the rate of outflow, internal friction coefficient etc.,
Index.When powder particle is sliding on the free inclined-plane of powder heap volume layer, suffered gravity and inter-particle friction power reaches balance
When, powder particle remains static.Physico-chemical property of the flow of powder performance mainly with powder in itself is relevant, such as particle is in itself
