Problems solved by technology

Due to the inevitable edge effect, the air permeability of the mixture in the middle is poor, and the air permeability of the mixture on both sides is good. Therefore, during the sintering process, the sintering speed of the mixture is different in the width direction of the trolley, and the mixing near the middle of the trolley The sintering speed of the material is slow, and it is prone to the phenomenon that it cannot be burned through. The sintering speed of the mixture located near the railing of the trolley is fast, and it is prone to over-sintering, resulting in uneven sintering quality and affecting the sintering efficiency.
At the same time, the traditional sintering machine bottom material swing funnel is tensioned by the counterweight 10, and the rotary gate is bulky, so the structure is complicated, the space occupied is large, and the manufacturing cost is high. It is also one of the shortcomings of the existing sintering machine bottom material swing funnel.

Embodiment Construction

[0021] As shown in Fig. 2 to Fig. 5, a swing funnel for sintering machine bottom material includes a funnel body 1, a rotary gate 2 and an adjusting gate device 3, the rotating gate 2 is installed in the middle of the funnel body 1, and the adjusting gate device 3 is installed It is arranged in front of the funnel body 1 and adjusts the height h of the gate 4 of the gate device 3 to decrease gradually from the middle to both sides. The sintering machine base material is laid on the grate plate of the trolley to achieve unequal thickness. The thickness of the base material layer 8 decreases from the middle to both sides, which can greatly reduce the adverse effects of the edge effect, so that the sintering material layer can be spread over the entire width of the trolley. The air permeability in the direction is basically the same, effectively reducing the phenomenon of uneven sintering speed, improving sintering quality and sintering efficiency. In the present embodiment, the ...

Abstract

The invention discloses a swinging hopper which can segmented adjust the height of sluiceway, reduce edge effect, improve sinter quality and sinter efficiency, with simple structure, small volume, and low cost, for laying bottom material in sinter machine. The invention comprises a body, a rotary sluiceway, and a sluiceway adjuster, wherein the rotary sluiceway is mounted at the middle of the body, the sluiceway adjuster is mounted at the front of the body, and the height of the sluiceway is reduced from middle to two sides.

Description

technical field [0001] The invention relates to the field of metallurgical sintering equipment, in particular to a swing funnel for a bottom material of a sintering machine. Background technique [0002] In the iron ore powder sintering process, because the particle size of the mixture is small (mostly less than 6mm), and even part of it is powder, its air permeability is poor. In order to increase the air permeability of the mixture and make the mixture fully combustible, a layer of bottoming material with a larger particle size (generally about 10-20mm) is often laid between the mixture on the sintering trolley and the grate plate of the trolley. layer. In this way, the gap between the grate plates of the trolley (about 6mm) will not be blocked by the mixture. At the same time, the bottom layer improves the air permeability of the entire material layer (including the mixture and the bottom layer), ensuring The ventilation effect is good, so as to obtain better sintering ...
