CIRCULAR COOLER AND TROLLEY BEARING BEAM THEREOF

摘要

Disclosed is a trolley bearing beam, comprising a front lateral plate (31), a rear lateral plate (32), a front vertical plate (33) and a rear vertical plate (34), wherein the front lateral plate (31) and the rear lateral plate (32) are respectively arranged tilted towards the two sides, and an upper edge of the front lateral plate (31) and an upper edge of the rear lateral plate (32) are fixedly connected, a front lateral ventilation grate plate (311) being provided on the front lateral plate (31); the front vertical plate (33) and the rear vertical plate (34) are located below the front lateral plate (31) and the rear lateral plate (32), and are respectively fixedly connected to the front lateral plate (31) and the rear lateral plate (32) to form a whole structure; a sealed space (35) with no through flow to a cooling air passage is formed between the front vertical plate (33) and the rear vertical plate (34); and a lower edge of the front lateral plate (31) and a lower edge of the rear lateral plate (32) respectively extend out of the front vertical plate (33) and the rear vertical plate (34), the upper edges of both being located in front of the vertical median plane of the sealed space (35). By means of optimised improvements to the structure, the trolley bearing beam has the advantages of a simple structure and a relatively light dead-weight, and a better space for piling ore material can be acquired, ensuring that the production efficiency of the circular cooler is effectively increased. On this basis, a circular cooler using this trolley bearing beam is further provided.
