Description

Technical Field

[0001] The utility model relates to a material discharging device, in particular to a device which can adjust the opening and closing angle of a material discharging hinge door and prevent oversized materials from falling onto a material distributing roller while adjusting the material discharging amount, and belongs to the technical field of sintering machine material discharging equipment. Background Art

[0002] In the field of sintered ore production, trolley-type sintering machines are mainly used, which have the advantages of high thermal efficiency, large operating area, and easy maintenance. However, due to the influence of material humidity and particle size, it is difficult to achieve stable control of the thickness of the material layer on the sintering machine trolley. Inadequate adjustment not only affects the quality of the sintered ore, but also easily causes material blockage, affecting production. The thickness of the material layer is currently mostly adjusted by a hinged door in conjunction with a circular roller. The control flexibility of the hinged door directly affects the thickness of the material layer on the sintering machine trolley. At present, in order to reduce costs, enterprises use a wide range of raw materials and fuels, and pellets have also become one of the ingredients. Pellets are defective products screened out during pellet smelting. The mechanical strength of the ceramic wear-resistant plate of the circular roller is not strong. If large pellets fall directly onto the circular roller, they will damage the ceramic wear-resistant plate of the circular roller. Therefore, an adjustable unloading device is needed. Under the premise of meeting the material distribution requirements under the existing opening and closing door structure, it is possible to prevent large pieces of pellets from falling directly onto the circular roller, reduce the wear of the circular roller, and increase the service life of the ceramic wear-resistant plate.
