Abstract
The utility model relates to an adding-ratio controller for sintering coal powder addition, which belongs to the ironmaking sintering field. In the utility model, a funnel-shaped buffer material bin 2 is arranged under a pelletizer 1, a feeder 3 is arranged on the outlet point on the bottom of the material bin 2, the feeding quantity of the feeder 3 is controlled by a frequency variable speed-adjusting motor 4, and a belt scale 5 is arranged under the feeder 3. After the belt scale 5 inputs weighing signals to a ratio regulator 11, and the weighing signals are compared with the set value, the rotation speed of the motor 4 is regulated by the regulator 11. The device can stabilize the mixed material flow rate on sintering machines.
Description
The utility model is a device of controlling solid fuel and iron content mix material proportioning in a kind of sintering process, belongs to the iron making and sintering field.
In the sintering process, the proportioning of solid fuel and iron content compound has important effect to the stabilized sinter quality.Patent CN1025749C provide a kind of substep granulation in two steps with addition of solid-fuelled method to improve the quality of products.Since the fluctuation that its first step is made the ball discharge be difficult to guarantee outer coal blending powder with addition of ratio, because that proportioning fluctuates is bad, wayward when causing on the sintering machine sinter quality fashion.Because the adjustment of proportioning need be from the proportioning room adjustment in the production process, lag time is long simultaneously.
The purpose of this utility model provides the outer coal blending powder of a kind of sintering with addition of proportional control apparatus.This device is used for regulating ball amount under the green pellets that gets off from the batcher green-ball to the belt, and forms control loop with coal dust with addition of device, by a certain percentage with addition of coal dust.
The purpose of this utility model is achieved in that
The sinter mixture facility for granulating and outside more than one green-ball buffering feed bin is set between the coal blending powder mixer, buffering feed bin outlet at bottom is installed a batcher, with the green-ball blanking amount of a frequency control motor adjusting batcher.The size of blanking amount is carried out weighing by the meausring apparatus under the batcher, and will relatively control its blanking amount with setting value in the weighing signal input ratio controller.
Below in conjunction with accompanying drawing the utility model is described in detail:
Fig. 1 is a work schematic diagram of the present utility model.
The utility model is laid a leakage below pelletizer 1 and green-ball transhipment belt 13 Bucket shape green-ball buffer bin 2, this feed bin 2 can be truncated cone or taper type, but circular cone Platform shape effect is best. A batcher 3, feed are installed by the outlet at bottom place of buffer bin 2 Machine 3 preferably adopts disk feeder. Batcher 3 is connected with a frequency control motor 4, Motor 4 is regulated the green-ball discharge quantity of batcher 3 by frequency control. Below batcher 3 Lay a belt conveyer scale or uclear scale 5, come weighing by the green-ball that gets off in the batcher with it Value. Belt conveyer scale 5 is connected with ratio controller 11 respectively with frequency control motor 4, The weighing signal of belt conveyer scale 5 is input in the ratio controller 11, through comparing with setting value After, ratio controller 11 output signals are regulated its rotating speed to frequency control motor 4, thereby The green-ball discharge quantity of control batcher 3. On the face of the storehouse of buffer bin 2, can stud with one deck 6～8mm is thick prevents the macromolecular material 12 that bonds.
The course of work of the present utility model is:
After the first step was made ball, the green-ball of being discharged by pelletizer 1 entered the slow discharging bin 2 of green-ball Buffer bin 2 is by batcher 3 discharges, and regulates batchers by frequency control motor 4 and turn to Speed, control green-ball discharge quantity. What of discharge quantity are by belt conveyer scale or uclear scale 5 weighings. The weighing signal enters ratio controller 11 and compares again by regulating the frequency conversion accent with setting value Speed motor 4 is controlled the discharge quantity of feed bin 2. Coal dust is distributed in from the batcher 7 under the Pulverized Coal Bin 6 Weighing coal dust weight on the coal dust weigh belt scale 9, this weighing signal also enter ratio and regulate Device 11 and the frequency control motor 8 of the relatively rear output signal of setting value to batcher 7 are regulated Thereby what of its rotating speed control coal dust discharge quantity, stablize coal dust with addition of amount. Green-ball Be discharged on the belt 10 with coal dust by belt conveyer scale 5 and 9 and be passed in the mixer.
The utility model can be stablized the proportioning of green-ball and coal dust, and can mix on the stable sintering machine Close materials flow amount, sinter quality and production operation.
Embodiment:
A 24m
2Sintering machine, adding two total measurement (volume)s is 35m
3 Buffering feed bin 2, disk feeder 3 feed abilities be 0～100 ton, the time, green-ball belt conveyer scale 5 ranges are 150t/h, Pulverized Coal Bin 6 volume 12m
