Novel coke silo chute

Technical Field

The utility model relates to a novel coke silo chute, and belongs to the technical field of metallurgical equipment.

Background

In the raw material circulation process, a coke silo is one link, because of special annular feeding, coke falls into a chute under the action of a scraping plate and centrifugation, the material can strike the inside diameter-changing position of a chute funnel under the action of centrifugation force in the traditional chute and falls on a lower conveying belt after striking for a plurality of times, firstly, the material can strike and abrade the diameter-changing position to cause chute leakage after entering the chute, and the material can be seriously prevented from being fed and forced to stop for welding repair; secondly, the existing coke is dry quenched coke, a large amount of powder is generated after multiple impacts, a large amount of smoke dust is generated when the coke passes through a chute, and the dust removal load is increased; 3. the environmental pollution can cause the dust of workers; 4. the coke size fraction will be destroyed during the blast furnace supply process, and the produced powdery or small particle materials will be sieved out, increasing coke consumption.

Disclosure of Invention

The utility model aims to provide a novel coke silo chute, by arranging a platform at the position of coke impacting the chute along a parabola I and the impacting position of refraction parabola II, the potential energy of materials is buffered, the damage of the chute caused by coke impacting the chute is avoided, smoke dust generated by impact of the materials falling to a downstream belt is reduced, the smoke dust treatment capacity is greatly reduced, the dust removing load is lightened, and the environment is effectively improved; the coke is accumulated on the two platforms to flow and discharge, so that the generation of crushed aggregates in materials is effectively relieved, the coke is effectively conveyed to a blast furnace, the loss is reduced, and the problems in the background art are effectively solved.

The technical scheme of the utility model is as follows:

a novel coke silo chute comprises a chute funnel, a first platform, a chute flow pipe and a second platform, wherein the chute funnel is connected with the chute flow pipe, the first platform and the second platform are arranged in the chute flow pipe, the first platform is arranged at the top end of the chute flow pipe, the second platform is arranged at the bottom of the chute flow pipe, the first platform is matched with the coke which is thrown out by an annular feeder and impacts the chute along a parabola, and the second platform is matched with the refracted parabola.

Further, the size of the second platform is matched with the diameter of the chute flow pipe.

Detailed Description

The following describes the technical scheme of the present utility model in further detail by referring to the accompanying drawings and examples, which are preferred examples of the present utility model. It should be understood that the described embodiments are merely some, but not all, embodiments of the present utility model; it should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

With reference to fig. 1 and 2, this embodiment provides a novel coke silo chute, including chute funnel 1, platform one 2, chute flow tube 3 and platform two 4, chute funnel 1 is connected with chute flow tube 3, and platform one 2 and platform two 4 set up in the inside of chute flow tube 3, and platform one 1 sets up on the top of chute flow tube 3, and platform two 4 set up in the bottom of chute flow tube 3, and the position of platform one 2 and coke are thrown out by annular feeder and strike the position phase-match of chute along parabolic one 5, and the position of platform two 4 and the second 6 striking position phase-match of refractive parabola.

The size of the second platform 4 is matched with the diameter of the chute flow pipe 3.

In practical application, the position of the platform I2 is determined according to the parabolic I of the annular feeder. When the coke is under the action of the annular feeder, the coke falls to the position of the platform I2 along the parabola I5, and part of the coke can be stored in the position, and when the coke impacts the position, part of potential energy is buffered; and a second platform 4 is manufactured at the next position where a second parabola 6 for refracting the coke impacts, the coke falls to the second platform 4, potential energy is relieved again by the stored coke, the flow direction of the coke falling to the next-stage belt is necessarily consistent with the belt direction, and foreign matters are prevented from falling to the next-stage belt, so that belt scratches are caused. The coke is accumulated to the first platform 2 and the second platform 4 to form the material beating function, so that the problem that the chute is damaged due to the impact of the coke on the chute is solved; secondly, stacking and flowing blanking among the cokes effectively relieves the generation of crushed aggregates in materials, and the cokes are effectively sent to a blast furnace, so that the loss is reduced; thirdly, buffering between materials and decreasing of drop potential energy reduce smoke dust generated by impact of the materials falling to a downstream belt, smoke dust treatment capacity is greatly reduced, dust removal load is lightened, and environment is effectively improved.
