Technical Field

The invention relates to the field of metallurgy, in particular to the field of roasting of iron ore concentrate pellets.

Background

In recent years, the steel industry in China continues to increase at a high speed, and the demand for iron ore is increasing. With the progress of blast furnace ironmaking technology, the 'concentrate' work is highly valued. Although the domestic production is in a growing development situation at present, the proportion of the output of the pellet ore which is one of the main components of the blast furnace charging material structure is very low compared with the raw materials required by the pig iron output, and more importantly, the performance of the finished pellet ore directly influences the blast furnace smelting and the whole steel production.

At present, the main method for producing the pellet ore in China adopts a belt type roasting machine, and the requirement on the stability of raw materials is high in the production process. This is because the whole process of roasting (drying, preheating, roasting, cooling) is carried out in the same equipment, and it is impossible to change the residence time of pellets in each stage by adjusting the machine speed. Such frequent switching, if any, is impractical in an actual production process unless the upper hood segment and windbox configuration are changed. Therefore, the construction of the belt type roasting machine is generally suitable for large-scale mining companies and iron and steel plants with long-term and stable raw material supply, has certain limitation, and is a technical problem brought by the use of the belt type roasting machine in the iron and steel smelting industry.

Further, the baking track is planar.

Further, independently drive the platform truck and include both sides platform truck lug, the upset discharge carriage is including upset discharge carriage recess, upset discharge carriage driving track and upset discharge carriage pivot.

Furthermore, the overturning discharging platform and the roasting furnace divide the roasting track into four stroke areas, namely a roasting area, an outlet waiting area, a discharging area and an inlet waiting area.

When the trolleys are positioned in the roasting area, the roasting process is executed, the running speed of each trolley is adjusted according to the quality difference and the quantity difference of green pellets in each trolley, and the aim that the action time of different trolleys in different process areas can be adjusted according to requirements is fulfilled; when the trolleys exit the roasting area, each trolley has different running speeds, the trolleys enter an exit waiting area, the speed of the trolleys is adjusted again in the area to keep the speed of each trolley consistent, and enough distance is reserved between every two trolleys; when the trolley drives into the discharging area, the trolley slides into a travelling track of the overturning discharging platform, trolley lugs on the side wall of the trolley are clamped into grooves of the overturning discharging platform on the two sides of the discharging platform to limit, and the overturning discharging platform is driven by an overturning motor to overturn downwards to complete the discharging of the trolley; and the trolley is reset to be aligned with the roasting track by reversing, the trolley runs out of the overturning unloading platform, the unloaded empty trolley recovers the running speed in the entrance waiting area, keeps the distance between the trolleys and loads materials, and then the unloaded empty trolley is matched with the speed of the trolleys and runs into the roasting area.

Compared with the prior art, the invention has the beneficial effects that: the automatic driving trolley is adopted, the trolleys with different running speeds can be conveyed in the drying, preheating, roasting and cooling stages, so that the running time of different procedures can be adjusted by each trolley according to the difference of the quality and the quantity of the pellets, the requirement for keeping the quality of raw materials stable for a long time is reduced, the roasting effect and efficiency are improved, and the stability of the quality of finished pellets is ensured.

The invention adopts the plane type roasting track, thereby facilitating the maintenance and replacement of the track and the trolley.

The overturning unloading platform is adopted to correspond to the self-driven trolley, the trolley is rotationally unloaded by driving the trolley body to rotate through the overturning motor and the overturning unloading platform rotating shaft, the overturning unloading platform travelling rail and the overturning unloading platform groove respectively correspond to the guide trolley to travel and correspond to the clamping trolley lug to limit, and the overturning unloading platform is convenient to unload and saves time and labor.
