The utility model provides a buffering type blast furnace raw fuel transfer station, includes material loading operation belt, transfer station hopper, buffer and unloading operation belt, and material loading operation belt sets up in transfer station hopper side top, sets up buffer at the junction of blast furnace raw fuel whereabouts orbit and transfer station hopper inboard, and transfer station hopper feed opening department sets up unloading operation belt. The utility model discloses the buffer that sets up simple structure, the installation of being convenient for is maintained, and has avoided the friction of each other of blast furnace raw fuel whereabouts process and hopper inner wall, has both reduced the powder rate of commentaries on classics of blast furnace raw fuel and has reduced the wearing and tearing and the routine maintenance of transfer station hopper again. The buffer device and the blast furnace raw fuel therein can play a role of buffering the reduction of the blast furnace raw fuel together, thereby effectively avoiding the powder conversion rate of the blast furnace raw fuel in the operation process and further reducing the production cost of iron.
Description
Technical Field
The utility model relates to a buffer type blast furnace raw fuel transfer station, which belongs to the technical field of blast furnace iron-making equipment.
Background
Today, the steel market has serious homogeneity, excess capacity and increasingly intensified competition, and only enterprises with quality improvement and consumption reduction for further reducing the cost have a foot. As the iron front system of the main body of 'cost reduction and efficiency improvement' of an enterprise, the iron front system is required to be produced around a blast furnace tightly, is grabbed from the source, improves the quality of raw fuel and the screening effect, and simultaneously reduces the generation of powder caused by secondary crushing of the raw fuel entering the blast furnace in the transfer process due to collision, reduces the powder entering the blast furnace in a multi-step mode, organically combines 'high-quality and efficient iron making' with 'economic iron making', and ensures that the furnace condition is smooth and various economic indexes are further improved.
Therefore, how to reduce the transfer rate of the raw fuel in the transfer process plays an important role in ensuring the smooth operation of the furnace condition and reducing the iron cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a buffer type blast furnace raw fuel transfer station, solve above-mentioned problem.
In order to realize the purpose, the utility model discloses a technical scheme is:
the utility model provides a buffering type blast furnace raw fuel transfer station, includes material loading operation belt, transfer station hopper, buffer and unloading operation belt, material loading operation belt sets up in transfer station hopper side top, sets up buffer at the junction of blast furnace raw fuel whereabouts orbit and transfer station hopper inboard, buffer sets up to length and is greater than blast furnace raw fuel flow width, height 500mm, width 500 and gives other reasons 1000 mm's open-top cuboid or top length be greater than blast furnace raw fuel flow width and bottom length and be less than top length, height 500mm, width 500 and gives other reasons 1000 mm's open-top cone, and transfer station hopper feed opening department sets up unloading operation belt.
The utility model discloses technical scheme's further improvement lies in: the buffer device is made of a common steel plate.
The utility model discloses technical scheme's further improvement lies in: according to the actual situation, one or more buffering devices are arranged by combining the height and the space of the transfer station hopper.
Since the technical scheme is used, the utility model discloses the technological effect who gains has:
the utility model discloses set up buffer with blast furnace raw fuel whereabouts orbit intersection in transfer station hopper inboard, the device simple structure, the installation of being convenient for is maintained, and has avoided the friction of each other of blast furnace raw fuel whereabouts process and hopper inner wall, has both reduced the powder rate of commentaries on classics of blast furnace raw fuel and has reduced the wearing and tearing and the routine maintenance of transfer station hopper again.
The utility model provides a buffer and blast furnace raw fuel wherein can play the cushioning effect that descends blast furnace raw fuel jointly, reduce the commentaries on classics powder rate of operation process blast furnace raw fuel effectively, the reasonable constitution of blast furnace raw fuel granularity produces positive influence to the gas permeability on blast furnace upper portion, produces favourable influence to the infiltration of blast furnace lower part iron slag and the rational distribution of stove steel initial coal gas even, has further reduced the manufacturing cost of iron.
Drawings
Fig. 1 is a schematic perspective view of the present invention;
wherein, 1, material loading operation belt, 2, transfer station hopper, 3, buffer, 4, unloading operation belt.
Detailed Description
The present invention will be described in further detail with reference to the following drawings and specific embodiments:
the utility model discloses a buffering type blast furnace raw fuel transfer station, for reducing a device that blast furnace raw fuel goes into the stove and causes the secondary crushing to produce the powder because of the collision in the transportation, the following is concrete example:
the utility model provides a buffer type blast furnace raw fuel transfer station, includes material loading operation belt 1, transfer station hopper 2, buffer 3 and unloading operation belt 4, and the raw fuel of blast furnace is the parabola orbit whereabouts along one side of material loading operation belt 1 under the drive of material loading operation belt 1. As shown in fig. 1, a transfer station hopper 2 is arranged below the side of the discharging side of a feeding operation belt 1, a buffer device 3 is arranged at the intersection of the falling track of the raw fuel of the blast furnace and the inner side of the transfer station hopper 2, a discharging operation belt 4 is arranged under the transfer station hopper 2, and the feeding operation belt 1, the transfer station hopper 2 and the discharging operation belt 4 are all the prior art.
The utility model discloses in the material that buffer 3 adopted be ordinary steel sheet, set up to top length 1200mm, bottom length and be less than top length, height 500mm, width 500 mm's open-top's cone. The top length of buffer 3 is greater than blast furnace raw fuel flow width, ensures that the blast furnace raw fuel of whereabouts all falls into buffer 3 on, buffer 3 and wherein raw fuel play the cushioning effect to the blast furnace raw fuel of whereabouts, avoids the pulverization of blast furnace raw fuel, has reduced the wearing and tearing and the routine maintenance of transfer station hopper simultaneously again.
The utility model discloses the example combines the height and the space of transfer station hopper, sets up 1 buffer 3 and can satisfy the function of avoiding former fuel whereabouts process and the friction of hopper inner wall, change powder.
The utility model discloses use the back, avoided the blast furnace raw fuel directly to fall to the violent collision of transfer bin bottom or take place strong collision with the wall of the bin hopper, reduced the whereabouts height and the collision strength of the raw fuel of blast furnace to reduce the raw fuel of blast furnace and at the transfer powder rate of transportation.
