The invention discloses a rotary cooler, two supporting vertical plate turning radius direction perpendicular to the rotary cooler is arranged between the grate plate and lower plate trolley, two supporting upright plate front end are arranged at the bottom of the accumulated material space, and between the two supporting board is fixedly arranged in connecting parts the radial distance; the inner support plate and the vertical trolley inside sealing plate between the radial distance from the lateral supporting vertical plate and lateral sealing plate between the trolley, vertical distance between the connecting part and the lower plate of the trolley, each supporting upright board product between the material containing space and the root of the car front supporting beam static sealing device of the week to the distance, and the height of the accumulated material containing space, is greater than a predetermined distance. The trolley lower plate of the invention can realize the smooth unloading of the local range of the car static sealing device, thereby effectively avoiding the defects of the static sealing of the trolley and the lower plate of the trolley due to the blocking of the front end of the vertical plate. On the basis of the invention, the invention also provides a ring refrigerator with the trolley.

本专利技术涉及钢铁冶炼领域,具体涉及一种环冷机台车及具有该台车的环冷机。
技术介绍
环冷机在钢铁企业中,用于冷却烧结的高温物料。环冷机整体呈圆环形,沿周向分为冷却区和非冷却区。运转过程中,待冷却的矿料自非冷却区的装料工位注入各环冷机台车,进入冷却区内后通过压力风对矿料进行冷却,而后各环冷机台车进入非冷却区的卸料工位,完成冷却和卸料。 现有环冷机台车为双层结构,上层为用于承载物料的篦板层,下层为结构平板层。公开号为CN101614479的专利文献具体公开了一种环冷机台车,其篦板11与台车下层平板12之间设有垂直于环冷机台车运转半径方向的第一支撑立板13、第二支撑立板14、第三支撑立板15、及第四支撑立板16。上述四个支撑立板均匀分担篦板11向下传递的压力。在台车体前置端的中部位置设有与台车前置支承梁联接的球铰装置,后置端沿径向设有两个沿导轨滚动的支承轮。在冷却作业区,两个支承轮支承在水平轨道上;在卸料作业区,台车进行卸料时,台车以球铰为中心向下转动,前置端与台车支承梁联接的球铰装置工位不变,台车支承轮沿卸料曲轨逐渐下降。随着台车体向后置端逐渐倾斜,台车上层篦板上的 ...
