Description
Technical Field
The utility model relates to a sintering machine cloth technical field especially relates to a sintering machine cloth system with variable roller segregation distributing device.
Background
The vast majority of sinter production adopts an air draft sintering process, and the effect of distributing materials on a machine head trolley directly influences the yield and quality of sinter. The requirement of the material distribution is that the mixture is uniformly distributed along the width direction of the trolley, and reasonable segregation is generated in the height direction of the material layer. At present, the segregation distributing devices of sintering machines at home and abroad can be roughly divided into four categories: magnetic rollers, air flow segregation, baffle plates, and multi-rollers. The reflecting plate type distributor and the multi-roller distributor are two distributing devices commonly adopted in domestic sintering plants, and the reflecting plate distributor has the advantages of good vertical segregation effect of distribution material, large range of material discharge granularity, no limitation of raw material conditions, capability of bearing the pressure of a feed column, uniform and reliable feeding, capability of realizing the beneficial segregation of mixed material granularity and fuel and simple equipment. The disadvantage is poor horizontal uniformity and the tendency to produce non-uniform layer structures, i.e. alternating layers. The multi-roller distributing device has the advantages of large distributing amount, wider distributing surface, capability of avoiding material collapse and capability of enabling the mixture to be uniformly distributed along the width direction of the trolley, namely good horizontal uniformity. The segregation generated by the mixture is superior to that generated by the material facing plate due to the multi-roller material distribution, but because the gear is adopted to transmit power, the parts are more, the energy consumption is more, the roller has serious damage to small balls, the roller body is too thin and too long and is easy to deform and wear, the equipment structure is relatively complex, the upper part of the variable roller is close to the igniter and is easy to dry lubricating oil, the utilization rate of the first roller at the upper part is low, the impact of the feeding at the upper part on the roller is large, and the problems of the granularity of the mixture and the reasonable distribution of carbon along the height direction of the mixture.
Chinese utility model patent application No. CN201420506587.9 discloses a "distributing device for mixture of sintering machine", which is a distributing device for mixture of sintering machine that performs both grain segregation and component segregation on the mixture. The distributing device comprises a multi-roller segregation distributing device and a magnetic rolling segregation distributing device, wherein the magnetic rolling segregation distributing device comprises a roller, a magnet arranged in the roller and a transmission device driving the roller to rotate around a central axis, and the magnet and the inner surface of the roller are arranged in a clearance mode. The device utilizes the multi-roller segregation distributing device to carry out particle size segregation on the mixture and simultaneously utilizes the magnetic rolling segregation distributing device to carry out segregation on the components of the mixture, thereby enhancing the air permeability of a mixture material layer on a sintering trolley and simultaneously segregating the magnetically sensitive material to an upper layer of the mixture on the sintering trolley. However, the upper part of the device is not used for guiding materials by a material receiving plate, the first roller of the multi-roller distributing device is useless, and the distributing device has little effect on component segregation.
