An equipment for the continuous, pneumatic introduction of finely divided materials, in particular coal dust, into several consumption sites, in particular into the tuyeres of blast-furnaces is characterized by combining systems partly known in such manner, that a plurality of double-story vessels is preceded by a distribution system comprising a supply bin with metering conveyor scale and distribution bin. A pressure-resistant bucket-wheel distributor is mounted underneath every pressure-vessel, the buckets of said distributor is multiply subdivided transversely to the axis, and a pressure-pan provided with conveyor-gas hook-up and subdivided into mini-chambers corresponding to the bucket-wheel distributor is mounted underneath each bucket-wheel distributor, the conveyor lines to the consumption sites being connected to the pressure-pan.

Equipment for the continuous pneumatic introduction of coal dust

A valve system for protection of the valve surface from abrasion and wear normally caused by the flow vertically therethrough of wear-causing materials, such as pulverized cement, sand, ashes, ground and stone dust, hydrated lime, zincoxide, zinc mixtures, aluminum oxide, perlite, sewage and other granulated or comminuted fluid materials in a dry or liquid state, often piped under considerable pressure differences, has an elongated vertical housing with a funnel on top, an annular seat with an orifice wider than that of the funnel beneath it, a bulbous valve for closing the seal from the side opposite of the funnel and protruding into the seat when closed, means of support of the valve pivotally attached to the valve and control means of the means of support, to swing the valve laterally in and out of sealing position with the seat. The valve, the means of support of the valve and the means to control the means of support are mounted within the housing so that in the valve-open position they are away from the flow path of the material and thus protected from the abrasive effects thereof. Means are provided to safeguard an airtight seal, even when coarse particles remain attached to the seal or other operating parts of the system and to increase the pressure of the valve against the seat.
