Abstract

The utility model provides a metallurgical converter loading attachment's lower hopper, belongs to hopper equipment technical field under the converter for improve the wearability of hopper down. Its technical scheme is: the utility model discloses welded the multilayer antifriction plate on the inner wall of hopper under, the antifriction plate is placed perpendicularly, is accepted by the top of antifriction plate when the material falls, has avoided the material to the direct striking and the friction of hopper inner wall down, and after the material filled up the clearance between the adjacent antifriction plate, the material of whereabouts was just fallen on the material in the space to along the material surface slip, the wearing and tearing that the material led to the fact have been reduced with the looks mutual friction of unloading headwall. The utility model discloses simple structure, convenient to use are reliable, can reduce the degree of wear of hopper inner wall down effectively to improve equipment life has reduced the number of times of maintaining with the equipment of change, greatly reduced maintenance work's intensity of labour, still practiced thrift material cost, have certain economic benefits.

Description

A kind of hopper of metallurgical converter feeding device
Technical field
This utility model relates to the hopper of a kind of metallurgical converter alloy material feeding device, belongs to converter charging equipment technical field.
Background technology
In smelting molten steel, being sufficiently fed the important step that various ore is steel-making efficiency and the steel quality improving converter, in the ore of ground blanking bin is transported to the process of high hopper of converter 48m, feeding device plays an important role.In actual production, the hopper of feeding device is often damaged, it is necessary to stop production maintenance, has not only upset rhythm of production, have impact on the quality of steel billet, also add production and maintenance cost.The reason that hopper damages is mainly the infringement to hopper of overload operation and material.First, the fast development produced result in the overload operation of hopper, the design charging capacity of hopper is 180t/h, needs along with production development, the charging capacity of the hopper of present converter feeding device is greatly improved, needing to increase to 240t/h 260t/h, the material of increase increases the tear strength to hopper inwall;Secondly, alloy material hardness is very big, and material profile has much sharp-pointed corner angle, and impact force and damage to hopper inwall are very big.In view of this, improving currently used hopper, the damage of minimizing hopper and frequency of maintenance are very urgent tasks.
Utility model content
Technical problem to be solved in the utility model is to provide the hopper of a kind of metallurgical converter feeding device, this hopper is in use it can be avoided that the material impact to bucket wall, reduce the material abrasion to bucket wall, increase the service life of hopper, reduce maintenance and production cost.
The technical scheme solving above-mentioned technical problem is:
A kind of hopper of metallurgical converter feeding device, it is made up of bucket wall and hopper bottom, bucket wall and hopper bottom have angle of inclination, its improvements are, hopper inwall four sides increases continuous wearing plate, wearing plate is vertically placed, the plate face of wearing plate and hopper inwall have angle of inclination, the lower end of wearing plate and hopper inwall are welded to connect, wearing plate is multilamellar, multi-layer wear-resistant plate successively arranges to lower end level from the upper end of hopper inwall, and the top of lower floor's wearing plate of adjacent two layers wearing plate and the bottom of upper strata wearing plate flush.
The hopper of above-mentioned metallurgical converter feeding device, the length of described every layer of wearing plate is identical, and the length of each layer wearing plate is gradually increased to hopper bottom by hopper top.
The beneficial effects of the utility model are:
This utility model has welded multi-layer wear-resistant plate on the inwall of hopper, wearing plate is vertically placed, accepted by the top of wearing plate when material falls, avoid material directly clashing into and friction hopper inwall, when behind the gap that material fills up between neighbouring wear-resistant plate, the material fallen just is fallen on the material in space, and slides along material surface.The shock of this utility model material and wearing plate and friction instead of the friction between original material and blanking headwall, it is to avoid material directly contacts with blanking headwall, reduce material and the phase mutual friction of blanking headwall and the abrasion that causes.
This utility model simple in construction, easy to use and reliable, it is possible to be effectively reduced the degree of wear of hopper inwall, thus improving service life of equipment, decrease and safeguard and the number of times of more exchange device, greatly reduce the labor intensity of maintenance work, also a saving material cost, have certain economic benefit.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, labelling is as follows: material 1, hopper 2, hopper inwall 3, wearing plate 4.
Detailed description of the invention
This utility model is made up of hopper 2 and wearing plate 4.
Showing in figure, hopper 2 is conventional discharging hopper structure, and hopper 2 is made up of bucket wall and hopper bottom, and bucket wall and hopper bottom have angle of inclination.
Showing in figure, the improvement of hopper 2 is to add wearing plate 4 on hopper inwall 3.Wearing plate 4 is vertically placed, and the lower end of wearing plate 4 and hopper inwall 3 are welded to connect.Owing to the hopper inwall 3 of hopper 2 has angle of inclination with vertical direction, therefore the plate face of wearing plate 4 and hopper inwall 3 have angle of inclination.
Showing in figure, wearing plate 4 is multilamellar, and multi-layer wear-resistant plate 4 successively arranges to lower end level from the upper end of hopper inwall 3, and the top of lower floor's wearing plate 4 of adjacent two layers wearing plate 4 and the bottom of upper strata wearing plate 4 flush.
Showing in figure, the length of every layer of wearing plate 4 is identical, and the length of each layer wearing plate 4 is gradually increased to hopper 2 bottom by hopper 2 top.
The wearing plate 4 of an embodiment of the present utility model, it vertically highly increases to 4cm from 1cm from hopper 2 top to bottom gradually.
Use procedure of the present utility model is as follows:
Material 1 falls from above, and bulk materials 1 first encounters wearing plate 4, the top of wearing plate 4 accept, it is to avoid bulk materials 1 directly clashing into and the friction of friction hopper inwall 3.Piece material 1 likely falls directly in the space between neighbouring wear-resistant plate 4, but owing to the gap between neighbouring wear-resistant plate 4 is little, the volume falling into material 1 therein is little, and impulsive force is very limited.Major part material 1 all first carries out colliding and rubbing with wearing plate 4 when falling into hopper 2, is substantially reduced material 1 to the shock of hopper inwall 3 and abrasion.When more material 1 falls subsequently, necessarily first pass through the friction of wearing plate 4, then collide with the interstitial material 1 of wearing plate 4, after space is filled, when material falls, material 1 collision rift directly and in space, slide into the bottom of hopper 2.
