Description

Technical Field

[0001] The utility model relates to the field of sintering equipment, in particular to a frame for a multi-stage sintering trolley. Background Art

[0002] A sintering trolley is a trolley for sintering ore used in the smelting of special steel plants. Its main function is to form a running rotary chain between the head and tail wheels of the sintering machine. It receives sintering mixture on the upper horizontal section, and after preheating, ignition, sintering, cooling, and material turning, it returns to the head wheel on the return journey to form a transmission cycle to achieve the purpose of sintering materials.

[0003] After retrieval, a split sintering trolley connecting plate with the application number CN202021571147.3 includes a supporting trolley body for supporting sintered parts and two side car bodies respectively arranged on both sides of the supporting trolley body. The two side car bodies are detachably connected to the supporting trolley body, and installation structures for installing grate bars are arranged on both the upper and lower sides of the supporting trolley body. By setting the supporting trolley body and the two side car bodies as a detachable split structure, the utility model can, after a certain amount of collapse occurs in the supporting trolley body, turn the supporting trolley body over and install components such as grate bars on the other side to support the sintered parts, that is, turn the collapse and downward bending of the trolley into upward arching. During subsequent use, the upward arching gradually flattens until it bends downward to a certain extent again, and then the supporting trolley body is turned over again. In this way, the entire supporting trolley body can be used in multiple cycles, without worrying about excessive collapse leading to the scrapping of the whole vehicle, which can greatly extend the service life and reduce production costs.

[0004] However, during the actual use of the sintering trolley, due to the need to achieve high-temperature firing, the flame is sprayed onto the trolley, and the high temperature will soften the steel of the trolley. After long-term operation, not only is the bearing platform of the sintering trolley prone to collapse, but the whole trolley, side plates, and frame will all show cracking or deformation. Since the trolley is an integral structure, if a part is damaged, the whole vehicle must be replaced, resulting in a relatively high replacement cost of the trolley and thus an increase in production costs. Therefore, a frame for a multi-stage sintering trolley is proposed. Summary of the Utility Model
