The utility model discloses simple structure, simple to operate is difficult for droing, assembles the back in the bottom of sintering pallet, enables to produce two great bleeder vents between two adjacent fire bars, has improved whole air permeability, has guaranteed the quality of sintering.
Description
Technical Field
The utility model relates to an improvement of fire bars for sintering pallet belongs to sintering equipment technical field, and specific high gas permeability fire bars for sintering pallet that says so installs the bottom of installing at the sintering pallet and uses.
Background
In the metallurgical industry, the sintering process is an essential process of various large iron and steel plants, and can combine powdered iron ore concentrate into large-particle iron-making raw materials with good air permeability. The bottom of the box of the conventional sintering trolley is provided with channel steel beams at intervals, a fire bar is placed between two adjacent channel steel beams and consists of a fire bar body, right-angle hooks and four fire bar lugs, the fire bar body is cuboid, the right-angle hooks are symmetrically and fixedly arranged at the bottoms of two ends of the fire bar body, two fire bar lugs are respectively arranged on the side walls of two sides of the fire bar body, the fire bar lugs on two sides of the fire bar body are mutually symmetrical, and after the fire bar bodies are installed, the two fire bar lugs between two adjacent fire bars are contacted with each other, so that three smaller air holes are formed between the two adjacent fire bars; during sintering, the prepared powdered iron concentrate material is accumulated on a fire bar of a sintering trolley, negative pressure is pumped from the bottom of the sintering trolley after high-temperature ignition, and fuel in the powdered iron concentrate material is combusted from top to bottom to complete the sintering process. The disadvantages of this grate bar are: because the air permeability between the material layer and the furnace bars in the sintering trolley is a main factor influencing the sintering quality, the gaps formed after the traditional furnace bars are contacted with each other are too small, the integral air permeability is seriously reduced, if the distance between the furnace bars is increased, powdery iron ore concentrate materials can fall below the furnace bars, and the materials can not finish the sintering work; in addition, because the common belt sintering is continuous operation, the sintering equipment is placed right half of the time and is suspended and poured half of the time, so that the furnace bars fall off individually, a special person is required to install and replace the furnace bars, and the operation intensity is increased.
Disclosure of Invention
An object of the utility model is to provide a simple structure, simple to operate is difficult for droing, enables to produce two great bleeder vents between two adjacent fire bars after the equipment, improves the high gas permeability fire bar for sintering pallet of whole gas permeability.
In order to achieve the above purpose, the utility model adopts the technical scheme that: this high gas permeability fire bar for sintering pallet, including fire bar body, fire bar ear and two right angle crotch, the bottom of setting at fire bar body both ends is fixed to two right angle crotch symmetries, and the free end of right angle crotch all faces outside its characterized in that: two sides of the fire bar body are arc-shaped concave surfaces, a fire bar lug is fixedly arranged in the middle of each arc-shaped concave surface, and the fire bar lugs on two sides of the fire bar body are symmetrical to each other.
The top surface of the free end part of the right-angle hook is fixedly provided with an upper boss, and a clamping groove is formed between the inner side edge of the upper boss and the vertical section of the right-angle hook.
The width of the outer end part of the furnace bar body is the same as the distance between the outer end faces of the two furnace bar lugs.
The beneficial effects of the utility model reside in that: simple structure, simple to operate is difficult for droing, assembles the back in the bottom of sintering pallet, enables to produce two great bleeder vents between two adjacent fire bars, has improved whole air permeability, has guaranteed the quality of sintering.

Detailed Description
The present invention is manufactured with reference to fig. 1, 2, and 3.
This high gas permeability fire bar for sintering pallet, including fire bar body 1, fire bar ear 3 and two right angle crotch 2, the bottom at 1 both ends of fire bar body is fixed to two right angle crotch 2 symmetries, and the free end of right angle crotch 2 all faces outside, its characterized in that: two sides of the fire bar body 1 are arc concave surfaces 6, a fire bar lug 3 is fixedly arranged in the middle of the arc concave surfaces 6, and the fire bar lugs 3 on two sides of the fire bar body 1 are symmetrical to each other.
The top surface of the free end part of the right-angle hook 2 is fixedly provided with an upper boss 4, and a clamping groove 5 is arranged between the inner side edge of the upper boss 4 and the vertical section of the right-angle hook 2.
The width of the outer end part of the furnace bar body 1 is the same as the distance between the outer end faces of the two furnace bar lugs 3, after the furnace bar is installed, the adjacent side faces of the outer end parts of the two furnace bar bodies 1 are in contact connection with each other, the outer end faces of the two opposite furnace bar lugs 3 are also in contact connection with each other, so that air holes are formed in the two sides of each furnace bar lug 3 respectively, and thus two air holes are formed between the two adjacent furnace bar bodies 1.
When the utility model is used, a plurality of channel steel beams 7 are arranged at the bottom of the sintering trolley at intervals, the channel steel beams 7 are made of channel steel, and the concave surface of the channel steel is installed downwards, so that the utility model is uniformly arranged between the two channel steel beams 7; during installation, the end parts of the two channel steel cross beams 7 are pushed into the other end, so that the clamping grooves 5 on the two sides are clamped on the side plates of the channel steel cross beams 7 on the two sides respectively, and the fixing is firm and cannot fall off. During material distribution, a layer of sintering material is paved above the fire bars of the sintering trolley, and then the powdery iron concentrate material is paved in a layered mode, large particles are located on the lower layer, small particles are located on the upper layer, and sintering quality is obviously improved.
