Description

Blast furnace sintered ore sampling device that goes into stove

Technical Field

The utility model relates to a steel production sintering especially relates to a blast furnace sintered ore sampling device that goes into stove.

Background

In the iron and steel pre-system of the integrated iron and steel enterprise, the sinter, which is one of the main raw materials of the blast furnace, is generally conveyed by a belt and then is thrown into a raw material ore tank of the blast furnace after being produced by a sintering plant. The vibrating screen is arranged under the ore tank, the sintering ore uniformly flows to the screen surface through the feeder below the ore tank, the small-sized ore (the size below 5mm generally controlled in the process is the small-sized ore) which is not in line with the use requirement of the blast furnace is screened out after passing through the screen surface, and the oversize material enters the weighing tank (the tail end of the vibrating screen and the upper part of the weighing tank are both arranged in the dust removal box) as the sintering ore which is in line with the size requirement of the blast furnace.

When the weight of the sintered ore in the weighing tank reaches a set value, the feeder below the ore tank stops vibrating, the sintered ore stops discharging, and then the vibrating screen stops vibrating. When the blast furnace feeding system program sends out the instruction of sintering ore feeding, the gate at the lower part of the weighing tank is opened, and the material is distributed on the belt. On a large blast furnace, the belt is used for feeding, so that the sinter is directly transported to the top of the furnace to complete the feeding process. The small blast furnace is loaded by the multipurpose skip car, so that the sintered ore placed on the belt from the weighing tank finally enters the skip car and is pulled to the top of the furnace by the skip car to complete the loading process.

For a blast furnace, the grain size composition of the sintering ore entering the furnace is an important index for evaluating the quality of the sintering ore, and the grain size composition of the sintering ore entering the furnace needs to be measured by performing screening experiments on the sintering ore entering the furnace regularly in production. And in the whole screening experiment process, the most important is whether the sampling is representative or not. For belt feeding of a large blast furnace, a part of material is generally cut from a belt as a screening sample after the belt is stopped in production. Although the operation is representative, the belt needs to be stopped, namely the feeding needs to be stopped. Therefore, the continuous production rhythm of the blast furnace is artificially disturbed, and the influence on the operation of the blast furnace is large. Meanwhile, when the belt conveyor is started after the material is taken out, the belt is fully paved with the sintered ore, the machine is required to be re-turned and started, and the re-turned and started machine can cause serious equipment accidents such as motor burning and the like, so that the serious equipment accidents are not paid. For the small blast furnace of skip material loading, can't take a sample in the skip, can stretch into the dust removal incasement with the spade and gather the sample that once sieved after the end material stream department of shale shaker samples many times and carry out the experiment. However, the sampling mode cannot completely cut off the material flow, so that the taken-out sinter is not representative, and finally the finally made grade index has no great guiding significance for blast furnace production.
