Abstract
Official abstract text for this publication.
A continuous concentrate feeding equipment of the present invention includes a plurality of concentrate supply mechanisms ( 50 ) each including a pressure-adjusting tank that temporarily accumulates granular concentrate; a lift tank that receives the concentrate from the pressure-adjusting tank ( 50 ) and discharges the concentrate to a smelting furnace; and a pressure control system that controls pressures of the pressure-adjusting tank ( 50 ) and the lift tank ( 51 ) such that the concentrate is continuously supplied from the lift tank to the smelting furnace throughout a time when the concentrate is received in the pressure-adjusting tank ( 50 ) and a time when the concentrate is discharged into the lift tank ( 51 ). The plurality of concentrate supply mechanisms ( 100 ) to ( 103 ) are connected in parallel to a conveyor for carrying in concentrate from an upstream side of the conveyor to a downstream side thereof. Supply control means is provided to control supply of the concentrate such that the concentrate reception of the concentrate supply mechanism is performed in order from the upstream side to the downstream side and the concentrate reception of the concentrate supply mechanism at an upstream end is started before the end of the concentrate reception of the concentrate supply mechanism at an downstream end.
First claim
Opening claim text (preview).
1 . A continuous concentrate feeding equipment, comprising: a plurality of concentrate supply mechanisms each including a pressure-adjusting tank that temporarily accumulates granular concentrate; a lift tank that receives the concentrate from the pressure-adjusting tank and discharges the concentrate to a smelting furnace; and a pressure control system that controls pressures of the pressure-adjusting tank and the lift tank such that the concentrate is continuously supplied from the lift tank to the smelting furnace throughout a time when the concentrate is received in the pressure-adjusting tank and a time when the concentrate is discharged into the lift tank, wherein the plurality of concentrate supply mechanisms are connected in parallel to a conveyor for carrying in concentrate from an upstream side of the conveyor to a downstream side thereof, and supply control means is provided to control supply of the concentrate such that the concentrate reception of the concentrate supply mechanism is performed in order from the upstream side to the downstream side and the concentrate reception of the concentrate supply mechanism at an upstream end is started before the end of the concentrate reception of the concentrate supply mechanism at a downstream end. 2 . The continuous concentrate feeding equipment according to claim 1 , wherein a time when the concentrate reception of the concentrate supply mechanism at the upstream end is started before the end of the concentrate reception of the concentrate supply mechanism at the downstream end in the supply control means is a time that precedes a time until the concentrate supply mechanism at the downstream end has completed receiving a total amount of the concentrate under the conveyor transport between the concentrate supply mechanisms at the upstream end and the concentrate supply mechanisms at the downstream end. 3 . The continuous concentrate feeding equipment according to claim 1 , wherein a service tank is provided between the pressure-adjusting tank and the conveyor.
