Abstract
The utility model discloses a blast furnace return ore blanking chute, which comprises a blanking chute right above a return ore conveying belt, wherein an upper plugboard is horizontally arranged on one side wall of an upper blanking point position at the upper part of the blanking chute, a lower plugboard is horizontally arranged at a blanking port at the lower end of the other side wall of the blanking chute, the lengths of the upper plugboard and the lower plugboard are smaller than the width of the blanking chute, and a movable door is hinged at the blanking port at the lower end of one side of the upper plugboard. Compared with the prior art, the utility model can solve the problems that the existing blast furnace return ore blanking chute has large return ore quantity, is easy to wear, and damages equipment due to the fact that the return ore is scattered outside.
Description
Technical Field
The utility model relates to the technical field of metallurgical mineral aggregate conveying equipment, in particular to a blast furnace return ore blanking chute of a mineral aggregate conveying device for iron making.
Background
The existing iron-smelting blast furnace return ores are conveyed by a belt generally, a discharging chute is arranged on a return ore conveying belt and comprises a belt, a discharging opening is obliquely arranged at the lower end of the discharging chute and is arranged right above the return ore conveying belt, and due to the large return ore quantity, the quality is heavy, the particles are small, when the return ores screened out of a feeder under the blast furnace trough are conveyed onto the return ore conveying belt through the discharging chute, the falling return ores are easy to wear and even wear due to long-term flushing of the discharging points of the chute, the return ores can spill outside, equipment is damaged, the cleaning workload and the labor intensity of workers are increased, the service period of the return ore discharging chute can be directly influenced, and the maintenance cost of the equipment is increased.
Disclosure of Invention
The utility model aims to solve the problems that the return ore blanking chute of the blast furnace is large in return ore quantity, easy to wear and easy to spill out of return ore and damage equipment when the conventional return ore blanking chute of the blast furnace is used for blanking.
In order to solve the problems, the technical scheme of the utility model is as follows: the blast furnace return ore blanking chute comprises a blanking chute right above a return ore conveying belt, wherein an upper inserting plate is horizontally arranged on one side wall of an upper blanking point on the upper portion of the blanking chute, a lower inserting plate is horizontally arranged at a blanking port of the lower end of the other side wall of the blanking chute, the lengths of the upper inserting plate and the lower inserting plate are smaller than the width of the blanking chute, and a movable door is hinged to the blanking port of the lower end on one side of the upper inserting plate.
Among the above technical schemes, more specific schemes may be: the length of the upper plugboard is 45% -55% of the width of the blanking chute.
Further: the length of the upper plugboard is smaller than that of the lower plugboard.
Further: the length of the upper plugboard is 50% of the width of the blanking chute.
Further: the distance between the upper inserting plate and the lower end discharging opening of the discharging chute is 800mm.
Due to the adoption of the technical scheme, compared with the prior art, the utility model has the following beneficial effects:
according to the blast furnace return ore blanking chute, an upper plugboard is arranged on one side wall of the upper blanking point of the blanking chute, a lower plugboard is arranged on the other side wall of the blanking port, the length of the upper plugboard and the lower plugboard is smaller than the width of the blanking chute, a staggered layer is formed, return ores screened from a feeder below the blast furnace chute directly fall on the upper plugboard, a dead material layer with a certain thickness is formed, new return ores fall onto the lower plugboard in a proper manner, a dead material layer is also formed, and the return ores fall onto a return ore conveying belt from the lower plugboard; the dead material layers formed on the upper and lower plugboards greatly relieve the impact force when the return ores fall, avoid abrasion to the side wall of the chute, prolong the service cycle of the chute, reduce maintenance cost, lighten labor intensity of workers, slow down the speed of the return ores and blanking, lighten the impact on the return ores belt, prolong the service life of the return ores belt and effectively solve the problem of deviation of the return ores belt; the movable door is arranged, so that the return ores and the abrasion conditions in the upper and lower plugboards can be conveniently checked.
Drawings
FIG. 1 is a front view of an embodiment of the present utility model;
the marks in the figure are as follows: an upper plugboard 1, a lower plugboard 2, a blanking chute 3, a movable door 4 and a return ore conveying belt 5.
Detailed Description
Embodiments of the utility model are described in further detail below with reference to the attached drawing figures:
the blast furnace return ore blanking chute shown in fig. 1 comprises a blanking chute 3 right above a return ore conveying belt 5, wherein an upper plugboard 1 is horizontally arranged on one side wall of an upper blanking point position on the upper part of the blanking chute 3, the distance between the upper plugboard 1 and a lower end blanking opening of the blanking chute 3 is 800mm, and the length of the upper plugboard 1 is 50% of the width of the blanking chute 3. The lower end blanking mouth of the side wall of the other side of the blanking chute 3 is horizontally provided with a lower plugboard 2, the lengths of the upper plugboard 1 and the lower plugboard 2 are smaller than the width of the blanking chute 3, and the length of the upper plugboard 1 is smaller than the length of the lower plugboard 2. The upper and lower plugboards are welded on the side wall of the blanking chute. The upper and lower plugboards form staggered layers, the lengths of the upper and lower plugboards are gradually increased, so that return ores screened from a blast furnace lower feeder directly fall on the upper plugboard 1, a dead material layer with a certain thickness is formed, the newly fallen return ores fall onto the lower plugboard 2 in a proper state, the dead material layer is also formed, and then fall onto the return ore conveying belt 5 from the lower plugboard 2; the dead material layers formed on the upper and lower plugboards greatly relieve the impact force when the return ores fall down, avoid abrasion to the side wall of the chute, prolong the service cycle of the chute, reduce maintenance cost, lighten labor intensity of workers, slow down the speed of the return ores and blanking through the buffer action of the upper and lower plugboards, lighten the impact on the return ores, prolong the service life of the return ores and effectively solve the problem of deviation of the return ores.
The blanking chute 3 is hinged with a movable door 4 at a blanking port at the lower end of one side of the upper plugboard 1, and the movable door 4 is hinged on a horizontal plate through a hinge shaft; the movable door 4 is arranged, so that the return ores and the abrasion conditions in the upper and lower plugboards can be conveniently checked.
In other embodiments, according to different working conditions, the length of the upper plugboard can be any value of 45% -55% of the width of the blanking chute.
