Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bulk material silo storage in coking enterprises, in particular to a silo for storing coking coal. Background Art
[0002] The Coal Coking Chemical Branch Company is affiliated to Inner Mongolia Baotou Steel Union Co., Ltd. and is a raw material production unit in the ironmaking front-end system, mainly responsible for providing qualified metallurgical coke for the blast furnace production in the downstream process. The main fuel for coke production is coking coal, and the main process is as follows: The raw coking coal is loaded into its respective coal storage silos according to varieties. After being fed by a disc feeder at a certain ratio, it is mixed on a large conveyor belt, conveyed by the conveyor belt to a crusher to meet a certain fineness requirement, and then sent to a coal tower by the conveyor belt as the raw material for coke oven production. After entering the coke oven, coking is carried out according to the specified coking time. After the coke is matured, it is discharged and quenched, and the finished coke is transported to the blast furnace of the iron plant for use.
[0003] Coking coal is the raw material for coke production. It belongs to bulk materials and has a relatively high moisture content. Based on environmental protection requirements, in order to avoid dust, bulk materials are not allowed to be stored outdoors. Therefore, in the industry, closed silos or closed storage yards are mostly used to store coal.
[0004] Coking coal belongs to bulk materials. Due to its washing process, its moisture content is relatively high, about 10%, and can reach more than 14% at high times. At the same time, some coal types have finer particle sizes and are prone to wall hanging and bridging.
[0005] In the prior art, the cross beams between the discharging openings in the silo are of steel-concrete structure. When coking coal is loaded from the top of the silo, part of the coal accumulates and hangs on the cross beams. As a result, in each silo with a storage capacity of 10,000 tons, there is often a situation where the discharging stops when there is still about 2,000 tons left. This situation is more serious for coal types with high moisture content and fine coal particles.
[0006] Because part of the coking coal accumulates on the cross beams during discharging. After the discharging opening in the silo stops discharging, when new coal is loaded, following the impact of the new coal during discharging, the original coal on the cross beams falls into the discharging opening. At this time, the new coal and the original coal on the cross beams have been mixed in quality, thereby affecting the quality of coke. And part of the newly loaded coal still accumulates on the cross beams, forming a cycle. Summary of the Utility Model
[0007] The purpose of the utility model is to provide a silo for storing coking coal to solve the problems existing in the above prior art, with a simple structure, convenient use, and effectively avoiding the occurrence of material accumulation and coal mixing phenomena.
[0008] To achieve the above purpose, the utility model provides the following scheme:
[0009] The utility model provides a silo for storing coking coal, comprising: a silo body and a sliding member. The silo body has a hollow cylindrical structure, and the silo body includes a plurality of discharging openings and a plurality of support beams. Each discharging opening is arranged at the bottom of the silo body, and the support beams are arranged between the discharging openings; the sliding member is arranged on the top of the support beam so that the coking coal in the silo body can slide to the discharging opening.
[0010] Preferably, the bottom surface of the sliding member is equal to the top surface of the support beam so that the sliding member can cover the top surface of the support beam, and the cross section of the sliding member gradually decreases from bottom to top.
[0011] Preferably, the sliding member includes two triangular plates, a bottom plate, a first side plate and a second side plate. The two triangular plates are arranged in parallel, and two ends of the bottom plate are respectively fixedly connected to the bottom edges of the two triangular plates. Two ends of the first side plate are respectively fixedly connected to the first side edges of the two triangular plates. Two ends of the second side plate are respectively fixedly connected to the second side edges of the two triangular plates.
