Good charging system can improve furnace processor level, improve smooth operation of furnace, and reduce fuel consumption.Without bell
Furnace roof is the development trend of modern blast furnace cloth system, and bell-less BF tep cloth is flexible and changeable, and chute can not only rotate, but also can be with
It swings；Both adjustable point cloth, theoretically swivel chute furnace charge can be wired to any position in stove, have it is circumferential uniformly, footpath
To it is adjustable the advantages of.Therefore can theoretically be reached by determining that chute angle and cloth doses formulate rational burden distribution system
Optimal cloth effect.But furnace charge particle experienced the object of the complexity such as extruding, friction, collision during by chute
Reason movement increases the difficulty of accurate cloth.
The content of the invention
The purpose of this utility model is to provide a kind of blast furnace material distribution chute, mainly solves existing blast furnace material distribution chute and exists
Furnace charge easily disperses in chute end during cloth, the drop point site of furnace charge is difficult to control the technology low with furnace charge cloth precision and asks
Topic；The utility model chute makes furnace charge tend to concentrate in chute motion process, and the drop point site for making furnace charge is more accurate, blast furnace
Accurately charging provides equipment guarantee to furnace roof.
The technical solution adopted in the utility model is a kind of blast furnace material distribution chute, including bottom plate, side plate, side plate and bottom
Plate is fixedly connected, and chute cross section is groove shapes, it is characterized in that：At least one is uniformly arranged on bottom plate along chute axis direction
Block wearing plate, wearing plate are rectangular steel plates, and wearing plate width is 100-150mm, the angle of wearing plate and backplate surface is 40 °-
50 °, the bottom end face of wearing plate is fixedly connected with bottom plate, and the both sides of the face of wearing plate are fixedly connected respectively with side plate；In chute
Portion is provided with material baffle above wearing plate, and the distance of end face of the material baffle front end face away from chute feed inlet side is chute
The 30%-40% of length, material baffle rear end face and the end face of chute discharge port side are same plane, and material baffle is that forepart is
" V " font steel plate, the angle of V-shaped is 90 ° -100 °, and material baffle both sides of the face are fixedly connected respectively with side plate, material baffle
15-25 ° of the angle of plane and backplate surface, vertical range of the material baffle away from bottom plate is more than at material outlet at material inlet
Vertical range of the material baffle away from bottom plate, chute are bilateral symmetry along longitudinal section where chute axis.
Wearing plate, bottom plate and side plate surround space for storing material, reduce abrasion of the material to bottom plate.
Further, the endface of chute discharge port side, material baffle is vertical away from for 200-400mm away from bottom plate, and effect is good；
The material direction of advance along chute, low setting after height before material baffle is presented, material baffle and end spaces before bottom plate are big, and end is empty
Between it is small, material baffle and base plate plane angle are 15 ° -25 °, not only can guarantee material direct motion in chute, but also can realize material
The effect collected in end；V-shaped is presented in front end, and the angle of V-shaped is 90-100 °, convenient for from the material that feed bin falls from V words
Shape space is by the way that smoothly into chute, main purpose is that material is prevented to pop up or skid off from chute side wall；V-shaped material
Baffle is symmetrical, and no matter chute rotates clockwise or can realize the effect that material collects when rotating counterclockwise；
The utility model has following good effect compared with prior art：The utility model apparatus structure is simple, is manufactured into
This is low, and baffle can prevent that material bounces splashing in chute and side wall skids off, and movement of the material in chute is prevented to go too far
It dissipates, material is made to tend to concentrate when leaving chute end, accurately charging provides equipment guarantee for blast furnace roof.
