Material distribution device and method for small-sized blast furnace bell-less equipment

Abstract

The invention relates to a material distribution device and method for small-sized blast furnace bell-less equipment, and belongs to the technical field of blast furnace top equipment of the metallurgical industry. According to the technical scheme, a material distribution channel is formed in a gap between an outer side shell of a bell-less body (14) and the bell-less body (15); and the outer side shell of the bell-less body (14) is fixed into a blast furnace end shell through a plurality of pull rods (10), the lower ends of the pull rods (10) are rotatably connected to the outer side shell of the bell-less body (14) through ball universal connection devices (13), and the upper ends of the pull rods (10) penetrate out of the blast furnace end shell (2) and are in driving connection with pull rod driving devices (11). The material distribution device and method have the beneficial effects that the structure is simple, the maintenance is convenient, the service life is long, material distribution of a small-sized blast furnace is convenient, blast furnace operation requirements are met, and blast furnace operation indexes are improved.

Description

technical field [0001] The invention relates to a material distributing device and method for small-sized blast furnace bellless equipment, and belongs to the technical field of blast furnace top equipment in the metallurgical industry. Background technique [0002] At present, in the field of blast furnace top equipment feeding technology in the metallurgical industry, bellless feeding equipment is widely used in large blast furnaces due to its superior material distribution performance and sealing performance, while small blast furnaces, such as blast furnaces below 200m3, due to the bellless The superior distributing performance of the rotary distributor does not play a great role in small blast furnaces. At the same time, because the bellless rotary distributor is more expensive, the furnace top equipment still adopts the traditional large and small bell top equipment; the traditional large and small bell Blast furnaces have many shortcomings, such as poor sealing perfor...

[0002] At present, in the field of blast furnace top equipment feeding technology in the metallurgical industry, bellless feeding equipment is widely used in large blast furnaces due to its superior material distribution performance and sealing performance, while small blast furnaces, such as blast furnaces below 200m3, due to the bellless The superior distributing performance of the rotary distributor does not play a great role in small blast furnaces. At the same time, because the bellless rotary distributor is more expensive, the furnace top equipment still adopts the traditional large and small bell top equipment; the traditional large and small bell Blast furnaces have many shortcomings, such as poor sealing performance of furnace top equipment, short service life of large and small material bells, poor production indicators of blast furnaces, more gas and dust leaked from the furnace top area, serious environmental pollution, and hazards to personal safety, etc. etc.; in order to ensure that the blast furnace below 200m3 adopts bellless equipment, it is necessary to develop a material distribution device suitable for small blast furnace bellless equipment. A must for furnace top equipment
