Problems solved by technology

[0003] The above segregation has the following disadvantages: on the one hand, during the parabolic movement of the material, it will cause particle size segregation in the material tank, resulting in uneven particle size of the material in the material tank. When the segregated material flows into the blast furnace, it will also cause the blast furnace The particle size segregation of the material in the furnace seriously affects the production efficiency of the blast furnace; secondly, during the parabolic movement of the material, it directly impacts the inclined inner wall of the tank, which accelerates the wear of the wear-resistant lining and affects the service life of the equipment

Embodiment 1

[0025] Such as Figure 2-4 As shown, the present invention provides a charging anti-segregation system, including at least two tanks 1 and an upper swing chute 2, the upper swing chute 2 is arranged above the tank 1, and also includes a separate tank 1 The anti-segregation device in the inner upper area or the anti-segregation device in the upper area and the lower area in the material tank 1 respectively, the anti-segregation device includes a concentration funnel 3 for charging and is used to fix the concentration funnel 3 in the material tank Positioning connection assembly 4 within 1.

[0026] Specifically, there are two material tanks in this embodiment, arranged in a tank type, and an upper swing chute 2 is arranged on it, and the upper swing chute 2 is used to put materials 6 into any material tank 2 according to production requirements. The upper area and the lower area in the tank 2 are each provided with an anti-segregation device to prevent material segregation dur...

Embodiment 2

[0032] Such as Figure 5 As shown, the difference between this embodiment and Embodiment 1 is that the inner wall of the concentration funnel 3 is provided with a detachable wear-resistant liner 9, when the wear-resistant liner 9 is damaged, it can be quickly replaced, and at the same time, It can also make the material 6 not be stored in the concentration funnel 3, which is beneficial to reduce the load of the concentration funnel. In addition, a layer of wear-resistant material 8 is coated on the surface of the wear-resistant lining 9 in direct contact with the material 6 by overlay welding, which can further protect the wear-resistant lining 9 to enhance the wear-resistant lining 9. abrasion resistance.

[0033] In the present invention, by rationally setting the anti-segregation device, the material can be discharged vertically during the charging process of the material tank, which effectively prevents the occurrence of material segregation, improves the uniformity of ma...

Abstract

The invention discloses a loading segregation-prevention system, and belongs to the technical field of metallurgical smelting equipment. The system comprises at least two material tanks and an upper swing chute. The upper swing chute is arranged above the material tanks, and the system further comprises a segregation-prevention device independently arranged on the upper area inside the material tank or segregation-prevention devices which are arranged on the upper area and the lower area inside the material tank; each segregation-prevention device comprises a concentration hopper for loading materials and a positioning connecting assembly for fixing the concentration hopper into the material tank; and according to the loading segregation-prevention system, the materials are vertically discharged in the loading process, material segregation can be effectively prevented, distribution uniformity of the materials in the material tanks is improved, the direct impact of the materials on the inclined walls of the material tanks is reduced, the service life of wear-resisting lining plates inside the material tanks is prolonged, and the system can be widely used for a blast-furnace bell-less top loading system or other vertical shaft type loading systems.

Description

technical field [0001] The invention belongs to the technical field of metallurgical smelting equipment, and relates to a shaft type furnace top technology, in particular to a charging anti-segregation system for a bellless furnace top charging system of a blast furnace. Background technique [0002] The blast furnace bellless top charging system is adopted by most of the blast furnaces in the world, but in the existing tank-merging or multi-tank bellless charging system, since the material tank deviates from the center of the blast furnace, when the material flows out from the feeding belt and When flowing into the tank through the upper swing chute, the trajectory of the material in the tank is a parabolic impact on the inclined inner wall of the tank, causing the material to segregate, such as figure 1 shown. [0003] The above segregation has the following disadvantages: on the one hand, during the parabolic movement of the material, it will cause particle size segregat...
