Abstract
The utility model relates to a blast furnace distribution chute. The blast furnace distribution chute consists of a chute body, a baffle plate which is connected with the chute body, and a nest-type liner plate which is connected into the chute body. The discharging end inside the chute body is provided with a trapezoid groove, and the trapezoid groove is connected with the nest-type liner plate. Due to the adoption of the blast furnace distribution chute, the distribution uniformity of the chute is good, the abrasion resistance of the linear plate is improved, the structure is simple, the application period of the chute can be improved, and the easiness in implementation can be achieved.
Description
Technical field
The utility model relates to iron-smelting blast furnace, specifically belongs to a kind of blast furnace material distribution chute.
Background technology
Distributor chute is one of key part in the blast furnace bell-less formula top charging equipment, and main effect is with burden distribution each position to burner hearth.The working position of distributor chute is the top in blast furnace chamber, the furnace charge of each batch of blast furnace according to corresponding frequency (according to different smelting requirements) thus rush at each position that distributor chute is distributed to burner hearth from material flow gate through about 8m high drop continuously.
Distributor chute mainly is made up of housing, liner plate two parts.For the blast furnace of present employing and pot type or multipot type, because distributor chute adopts circular, therefore chute easily lost efficacy in actual production, it is the easy scaling loss of housing of chute, the long-pending nest formula liner plate of chute is easy to wear, causing distributor chute stream material inhomogeneous, easily produce segregation, is one of smelting process for production factor that influences in blast furnace.
People have developed a kind of square casing structural shape blast furnace material distribution chute in order to overcome the existing deficiency of circular distributor chute, find that in use square blast furnace material distribution chute exists heating surface area big and influence whole distributor chute work-ing life.
The utility model content
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of cloth evenness of chute that can make good, and the liner plate wear resistance is good, and is simple in structure, and can improve the blast furnace material distribution chute of the life cycle of chute.
Realize the technical measures of above-mentioned purpose:
A kind of blast furnace material distribution chute, by chute body, the baffle plate that is connected with the chute body, be connected in the intrinsic long-pending nest formula liner plate of chute and form, it is: at the intrinsic discharge end of chute, be provided with dovetail groove, dovetail groove is connected with long-pending nest formula liner plate.
It is characterized in that: the length of dovetail groove is no more than 1/5th of chute length overall.
Characteristics of the present utility model are: can make the cloth evenness of chute good, the liner plate wear resisting property improves, and simple in structure, the life cycle of chute can be improved, and easily implements.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional view among Fig. 1;
Among the figure: 1-chute body, 2-baffle plate, 3-long-pending nest formula liner plate, 4-dovetail groove.
Embodiment
Be described further below in conjunction with accompanying drawing:
A kind of blast furnace material distribution chute is made up of chute body 1, the baffle plate 2 that is connected with chute body 1, the long-pending nest formula liner plate 3 that is connected in the chute body 1.Its discharge end in chute body 1 adopts whole processing or embedded mode to connect dovetail groove 4, and the length of dovetail groove 4 is no more than 1/5th of chute length overall and gets final product; Dovetail groove 4 is close to mode with long-pending nest formula liner plate 3 employings or inserted mode is connected.
Claims (2)
1. blast furnace material distribution chute, by chute body, the baffle plate that is connected with the chute body, be connected in the intrinsic long-pending nest formula liner plate of chute and form, it is characterized in that: at the intrinsic discharge end of chute, be provided with dovetail groove, dovetail groove is connected with long-pending nest formula liner plate.
2. a kind of blast furnace material distribution chute as claimed in claim 1, it is characterized in that: the length of dovetail groove is no more than 1/5th of chute length overall.
